What are jigs?
Before painting, before the engine, chassis parts or trim (glass, door locks/handles, seats, trim, A jig is a large brace that keeps a welding project stable in the face of pressure, heat, motion, and force. A quality jig will streamline welding work by keeping parts together in a vice grip. Whether the welding is entirely manual, partially automatic, or fully robotic, a jig moves the workpiece while the tool remains stationary.
Before painting, before the engine, chassis parts or trim (glass, door locks/handles, seats, trim, electronics, etc.) are integrated into the structure. Assembling a "body in white" involves various techniques such as welding (spot, MIG/MAG), riveting, clinching, gluing, and laser soldering.
In the "Body-in-White" project, we made fixture parts for spot welding technology for various car models. Incorporate welding fixtures, vehicle body skeleton assembly fixtures, Side enclosure fixtures, underbody fixtures, Rear floor fixtures and robotic grippers, etc.
Jigs Types
1. Manual jigs
Manual jips are composed of fixed, moving, clamping, and other components and mechanisms, through the manual knob, handle, and other control mechanisms to complete the clamping action. Its working principle is based on mechanical principle and hydraulic principles.
2. Semi-automatic jips
Based on manual jips work, we will be equipped with automatic jips or pneumatic jips, which can efficiently complete the work of production, effectively improving the production efficiency, of course, the accuracy will also be improved.
3. Automatic jigs
The automatic clamp is an electromechanical device used in conjunction with manipulators, machine tools, and automation equipment, mainly for clamping objects and processing. Its working principle mainly includes the following aspects: Clamping/unclamping operation, Mobile operation, Detection, and control system.
We could design jigs according to customer needs.
Car jigs are custom-designed, and we will design the type of fixture that better meets your needs based on your production line equipment. Customized fixtures not only ensure the accuracy of body welding but also improve the efficiency of the welding process. We design fixtures with high efficiency; good quality; precision machining; good fixation of fixture devices; software automation, design automation, efficiency increased by more than 30%; design standardization, 80% of the parts are standardized in the design stage, shortening the delivery time and reducing costs.
Jigs composition
In general, a welding jigs tool consists of several units together to hold the car panel and is mounted on a base unit. The fixture has to be quite stable and rigid to withstand the welding stresses.
Base plate: after the assembly plate has been milled, it is inspected using three seated axes, the main job of the base is to maintain absolute balance, carefully designed to prevent distortions during welding.
brackets: Linking substrates and positioning blocks. The sturdy that houses the workpieces to be machined. Ensure proper component placement and stability to withstand welding stresses.
positioning block: The use of 45# steel blackening treatment, after carburisation treatment, so that the positioning block is more stable, and wear-resistant, prolonging the durability of products. These components ensure precise workpiece positioning relative to the welding tool. These elements guide the welding tool, while in fixtures, they facilitate proper tool engagement.
clamping block: Various fastening devices that secure the jig or fixture in the correct machine position. Used to securely hold the workpiece in its located position.
Application of jigs
Car jigs are widely used in various fields of industrial production, mainly used to clamp the workpiece and tool, to ensure the safety of the workpiece and processing accuracy. In machining, metal processing, workshop maintenance, automation, and other fields,jigs have important application value. For example, the use of rail clamps in machine tools can effectively ensure the accuracy and stability of the workpiece, and improve production efficiency and quality; in the manufacture of large-scale machinery and equipment such as automobiles, rail clamps are also indispensable and important components, which can improve the production efficiency and quality of production. As a common industrial equipment, Jips are widely used in various fields of industrial production because of their high clamping force, high precision, and simple operation.
Car assembly jigs are tools used to secure, position, or support vehicle components during production and maintenance. They play a crucial role in ensuring installation accuracy and improving work efficiency. Below is an introduction to the primary functions of car assembly jigs:
1. Fixation Function
Stable Positioning: Jigs can securely hold Car parts in place, preventing them from shifting or slipping during installation. This is especially important for components that require precise positioning, such as doors, windows, and dashboards.
Consistency Maintenance: Using jigs ensures that the same type of component is installed in the same way across different vehicles, maintaining product consistency and quality.
2. Support Function
Providing Support: During installation, jigs can support heavy or large components, such as body panels or engines, reducing the difficulty of operation and preventing deformation or damage due to gravity.
Reducing Workload: By supporting the components, jigs reduce the physical effort required to hold or support them, thereby increasing work efficiency.
3. Positioning Function
Precise Positioning: Jigs can accurately position Car components during installation, ensuring correct alignment with other parts. This is crucial for installing complex components or those requiring high precision, such as suspension systems and wheel axles.
High Repeatability: Through the positioning function of jigs, high precision and repeatability can be achieved in mass production, reducing human error.
4. Safety Function
Preventing Damage: Jigs can prevent components from being accidentally bumped or damaged during installation, especially when handling fragile or sensitive materials.
Protecting Operators: By securely holding and supporting components, jigs reduce the risk of components unexpectedly slipping or moving, ensuring the safety of the installation process.
5. Process Simplification Function
Simplifying Operations: Jigs can break down complex installation processes into simple operational steps, making the process more intuitive and easier, thereby reducing operation time.
Improving Efficiency: Using jigs can speed up the installation process, significantly increasing production efficiency, especially in mass production.
6. Calibration and Adjustment Function
Adjustment Function: Some jigs are designed with adjustment capabilities, allowing for fine-tuning during installation to ensure final installation accuracy.
Calibration Function: During installation, jigs can also assist in calibrating the position and angle of components, ensuring they are installed in optimal condition.
Overall, Car assembly jigs are indispensable tools in the production and maintenance process. They not only enhance installation precision and efficiency but also ensure operational safety and consistency.

Jigs advantage
1. sufficient rigidity and strength: in the production process the car jigs need to withstand a variety of forces, so the fixture must have sufficient rigidity and strength to apply to a variety of forces.
2. reliability: the workpiece in the production process, does not allow any deviation. Can not move the positioning position of the workpiece and can not make the product shape deformation, therefore, the automotive welding fixture needs to have a high degree of reliability.
3. Flexibility: In order to ensure sufficient welding space, so that the operator has a certain field of vision and operating space, automotive welding fixtures need to have a certain degree of flexibility.
4. Convenience: the product can be smoothly removed after the completion of the process, without being damaged, so the automotive welding fixture needs to be convenient, easy to operate, and maintain.
5. Superior technology: the design of automotive welding fixtures requires superior technology to ensure that it can achieve the best results in the process of use.
