The above device has the problem of unstable positioning and relatively single positioning of the side panel, which may cause the side panel to fall off when the parts are installed. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a car side panel positioning clamp with excellent fixation in view of the deficiencies of the above-mentioned prior art. The car side panel positioning clamp with excellent fixation provides good fixing and positioning effects for the car side panel through the joint action of the horizontal positioning clamp, the vertical positioning clamp, the supporting positioning clamp and the connecting parts.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A car side panel positioning fixture with excellent fixability is used to provide fixation and positioning for the car side panel, including a base plate, a connecting piece, a positioning assembly and a driving assembly. A plurality of the connecting pieces are arranged on the base plate. The positioning assembly is used to fix the car side panel. The positioning assembly is arranged on the base plate through the connecting piece. The driving assembly is used to drive the positioning assembly to clamp and position the car side panel. The driving assembly is a plurality of driving cylinders, and each positioning unit of the positioning assembly is connected to the driving cylinder.

[0007] Furthermore, the positioning assembly includes a lateral positioning fixture, a vertical positioning fixture and a supporting positioning fixture. A plurality of lateral positioning fixtures are provided and are installed on the base plate through the connecting member. A plurality of vertical positioning fixtures are provided and are fixed to the base plate through the connecting member. A single supporting positioning fixture is provided and is fixed to the base plate through the connecting member.

[0008] Through the multiple settings of the horizontal positioning fixture and the vertical positioning fixture, the automobile side panel can be comprehensively and accurately positioned from different directions to ensure the position accuracy of the automobile side panel during welding or assembly, and avoid quality problems caused by position deviation. Multiple horizontal and vertical positioning fixtures can be flexibly adjusted according to the specific shape and size of the automobile side panel to meet the positioning requirements of different models and parts, thereby improving the versatility and adaptability of the fixture. The design of the supporting positioning fixture can provide strong support to prevent the automobile side panel from being deformed due to uneven force during welding or assembly, thereby ensuring the stability of the overall structure. All positioning fixtures are fixed to the base plate through connectors for easy disassembly and replacement, shortening the maintenance and adjustment time, and also facilitating standardized production and maintenance management. The comprehensive and precise positioning system greatly improves the assembly efficiency and quality of the automobile side panel, reduces the rework rate, indirectly saves production costs, and improves the overall economic benefits.

[0009] Furthermore, a cushion block is provided below the connecting piece corresponding to the bottom of the vertical positioning fixture, and the cushion block is fixed to the base plate by bolts.

[0010] The presence of the pad can increase the contact area between the vertical positioning fixture and the base plate, thereby improving the overall stability of the fixture and preventing deformation of the base plate or loosening of the fixture due to uneven force when clamping the car side panel. The height can be adjusted by replacing the pad, so that the vertical positioning fixture can be accurately positioned in height according to the actual thickness or assembly requirements of the car side panel to adapt to different car models or production needs. The pad can play a buffering role, reduce the wear of the vertical positioning fixture when it is in direct contact with the base plate, protect the fixture and the base plate from damage, and extend the service life of the equipment. The pad is generally made of anti-slip material, which can effectively prevent the fixture from sliding during the clamping process. At the same time, it can also absorb part of the vibration energy and reduce vibration and noise during work. The pad can effectively disperse the pressure of the vertical positioning fixture on the base plate and improve the overall bearing capacity and safety of the fixture.

[0011] Furthermore, the connecting part is a sheet metal bending part, including a bearing part, a supporting part and a connecting part, the bearing part and the connecting part are "L"-shaped as a whole, the supporting part is welded between the bearing part and the connecting part, and screw holes are opened in the connecting part and the bearing part to respectively connect the base plate and the positioning assembly.

[0012] The "L"-shaped structure formed by the sheet metal bending process has higher structural strength and stability than a single flat plate structure, and can better withstand various torques and pressures from the positioning process of the automobile side panel, ensuring the fixation and durability of the positioning fixture. The load-bearing part, the supporting part and the connecting part are tightly combined into one by welding, making the overall structure more compact and firm, avoiding the loosening or breakage problems that may occur in the splicing of multiple parts. The pre-opened screw holes on the connecting part and the load-bearing part can be easily and quickly connected and fixed to the base plate and the positioning assembly without the need for additional drilling, which significantly improves the assembly efficiency while also ensuring the accuracy and strength of the connection.

[0013] Furthermore, the driving cylinder is connected to the positioning assembly via bolts.

[0014] Bolt connection is a reliable fixing method, which can ensure the tight and stable connection between the driving cylinder and the positioning component, and avoid the positioning accuracy and stability affected by loose connection during operation. The bolt connection method makes the installation and disassembly between the driving cylinder and the positioning component more convenient, which is beneficial to the daily maintenance, overhaul and replacement of parts of the equipment. By adjusting the bolt preload, the tightness of the connection can be appropriately changed to adapt to different workloads and environmental conditions and optimize equipment performance. Driving cylinders or positioning components of different models and specifications can be interchanged through bolt connection as long as the interface sizes match, which improves the versatility and upgradeability of the equipment. Compared with irreversible connection methods such as welding, bolt connection will not damage the original structure when a failure occurs or parts need to be replaced, which is more in line with the principle of sustainable use of equipment.

[0015] Furthermore, a foot is provided at the bottom of the base plate, and a plurality of clearance openings are provided on the base plate, so that the driving cylinder of the transverse positioning fixture passes through the base plate through the clearance openings.

[0016] The design of the foot pads can increase the contact area between the equipment and the ground, reduce the shaking and instability of the equipment during operation, and improve the overall stability. The foot pads usually have an anti-slip design, which can not only prevent the equipment from sliding, but also protect the ground from being worn by the heavy pressure of the equipment. Through the design of the clearance port, the driving cylinder can pass under the base plate, making the cylinder layout more reasonable and compact, reducing the occupied space while facilitating the installation, maintenance and replacement of the cylinder. The clearance port design can avoid direct conflict between the cylinder and the base plate, optimize the internal structure of the equipment, and make the overall layout more scientific and reasonable. In addition to the cylinder itself, the clearance port also provides a channel for the cylinder pipeline, making the layout of accessories such as air pipes and wires more convenient and orderly, avoiding mutual interference and entanglement.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model is provided with multiple configurations of horizontal positioning fixtures and vertical positioning fixtures, which can accurately position the automobile side panels from different dimensions, ensuring that the automobile side panels can be effectively fixed in all directions during the assembly or welding process, thereby improving the assembly accuracy and quality. Multiple positioning fixtures can be flexibly adjusted according to different sizes of different models and body parts, thereby realizing rapid and accurate positioning of automobile side panels of various complex shapes, thereby enhancing the versatility and adaptability of the equipment;

[0019] 2. All positioning fixtures are fixed to the base plate through connectors, which makes the installation, disassembly and maintenance of the fixtures very convenient, and also facilitates the updating, upgrading and expansion of the equipment. The comprehensive use of multiple positioning fixtures to work together can significantly improve the positioning speed and work efficiency of the automobile side panel, reduce manual intervention, reduce the error rate, and ultimately improve the production capacity and quality of the entire production line.
