Description

Technical Field

[0001] The utility model relates to the technical field of support mechanisms, in particular to a support mechanism for automobile chassis welding. Background Art

[0002] In the production of automobile chassis, the welding process is mainly used to connect chassis components such as vehicle frames and suspension systems. With the continuous progress of welding technology and equipment, various efficient and stable welding processes such as automatic welding, semi-automatic welding, and robot welding have emerged one after another and are widely used in automobile chassis welding.

[0003] When welding the automobile chassis, most of the commonly used supports for the chassis are single-structured support frames. Placing the chassis directly on the support frame for welding easily causes the chassis to displace, thereby affecting the welding accuracy and quality. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the above-mentioned equipment is used, due to the relatively single existing support mechanism, the chassis is prone to displacement during welding, affecting the welding quality, and a support mechanism for automobile chassis welding is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A support mechanism for automobile chassis welding, including a support frame, two support columns are fixedly installed at the bottom of the support frame, holes are opened on the outer surface of the support frame, two square holes one are opened at the top of the support frame, a bidirectional threaded rod is movably inserted into the inner surface of the hole, and two moving sliders are threadedly connected to the outer surface of the bidirectional threaded rod.

[0006] Preferably, connecting plates one are fixedly installed at the tops of the two moving sliders, fixing plates are fixedly installed at the tops of the two connecting plates one, and a driving motor is arranged on one side of the outer wall of the bidirectional threaded rod.

[0007] Preferably, two anti-slip pads are arranged at the top of the support frame, and a controller is arranged at the top of one of the two support columns.

[0008] Preferably, two groups of positioning holes are opened at the top of the support frame, and positioning pins are movably inserted into the inner surfaces of the two groups of positioning holes.

[0009] Preferably, two square holes two are opened at the top of the support frame, and connecting plates two are fixedly installed on the inner surfaces of the two square holes two.

[0010] Preferably, two mechanical grippers are fixedly installed at the tops of the two connecting plates two, and a pressure sensor is arranged at the top of one of the two connecting plates two.

[0011] Preferably, a displacement sensor is provided at the top of one of the two connecting plates II.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] In the present utility model, the operation of the driving motor can drive the relative movement of the two fixing plates to fix the vehicle chassis, ensuring that the chassis maintains an accurate position and posture during the welding process, reducing welding errors caused by position deviation. Through clamping and fixing, the chassis is not prone to shaking or deformation during the welding process, thereby improving the stability and consistency of welding, and preventing damage or deformation of the chassis caused by external forces during the welding process.

[0014] In the present utility model, firstly, the two anti-slip pads can effectively increase the friction between the support mechanism and the chassis, preventing the chassis from sliding or shifting during the welding process due to vibration or external forces. Secondly, the chassis can be positioned and fixed through the cooperation of the positioning holes and the positioning pins. At the same time, the vehicle chassis can be firmly clamped by the mechanical gripper to ensure the stability and accuracy of the chassis position during the welding process. Secondly, through the cooperation of the pressure sensor, the displacement sensor and the controller, the pressure sensor can accurately measure the pressure borne by the chassis support points during the welding process, ensuring uniform pressure distribution during the welding process, avoiding excessive local pressure causing chassis deformation or reduced welding quality. At the same time, combined with the data of the displacement sensor, automatic control of the welding process can be realized, reducing manual intervention and improving production efficiency and welding quality.

Detailed implementation mode

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figure 1 、 Figure 2 shown, the present invention provides a support mechanism for automobile chassis welding, including a support frame 1. Two support columns 2 are fixedly installed at the bottom of the support frame 1. A hole 3 is formed on the outer surface of the support frame 1. Two first square holes 4 are formed at the top of the support frame 1. A bidirectional threaded rod 5 is movably inserted into the inner surface of the hole 3. Two moving sliders 6 are threadedly connected to the outer surface of the bidirectional threaded rod 5. First connecting plates 7 are fixedly installed at the tops of the two moving sliders 6. Fixed plates 8 are fixedly installed at the tops of the two first connecting plates 7. A driving motor 9 is arranged on one side of the outer wall of the bidirectional threaded rod 5.

[0024] The overall effect achieved by the entire Embodiment 1 is that first, the bidirectional threaded rod 5 is threadedly connected to the two moving sliders 6, and the bidirectional threaded rod 5 is also connected to the driving motor 9. By running the driving motor 9, the bidirectional threaded rod 5 can be driven to rotate, thereby driving the two moving sliders 6 to move. The two moving sliders 6 are connected to the fixed plates 8 through the first connecting plates 7. Finally, the two fixed plates 8 can be driven to move relative to each other to fix the chassis, which can effectively prevent safety accidents caused by accidental slipping of the chassis during the welding process. The stable support and clamping provide a safer working environment for welding operators and reduce the operation risk.

[0025] Embodiment 2, as Figures 1-4As shown in the figure, two anti-slip pads 10 are provided at the top of the support frame 1. A controller 11 is provided at the top of one of the two support columns 2. Two groups of positioning holes 12 are formed in the top of the support frame 1. Positioning pins 13 are movably inserted into the inner walls of the two groups of positioning holes 12. Two square holes 14 are formed in the top of the support frame 1. Connecting plates 15 are fixedly installed on the inner walls of the two square holes 14. Two mechanical grippers 16 are fixedly installed on the top of each of the two connecting plates 15. A pressure sensor 17 is provided on the top of one of the two connecting plates 15. A displacement sensor 18 is provided on the top of one of the two connecting plates 15.

[0026] The overall effect achieved by the entire Embodiment 2 is that during the normal use of the device, the stability during the welding process can be ensured through the action of the two anti-slip pads 10. Therefore, it helps to reduce the rework phenomenon caused by welding position deviation, saving time and resources. Secondly, by aligning the holes on the chassis with the positioning holes 12, and then inserting the positioning pins 13 into the positioning holes 12 to fix the chassis, a stable support can be provided for the chassis, preventing the chassis from shaking or deforming due to vibration or external forces during the welding process. Secondly, through the fixation of the mechanical grippers 16, the chassis is not prone to shaking during the welding process, thereby reducing welding errors and improving welding quality. At the same time, the real-time monitoring of pressure changes by the pressure sensor 17 helps to reduce welding defects caused by uneven pressure during the welding process. And by combining the data of the displacement sensor 18, automatic control of the welding process can be achieved, reducing manual intervention and improving production efficiency and welding quality.

[0027] Among them, the drive motor 9, the controller 11, the mechanical grippers 16, the pressure sensor 17, and the displacement sensor 18 are all prior arts. Their components and operating principles are all publicly known technologies and will not be explained in detail here.

[0028] Working principle: First, when the device is in normal use, place the vehicle chassis on the support frame 1. Secondly, a bidirectional threaded rod 5 is movably inserted into the inner wall of the hole 3. Two moving sliders 6 are threadedly connected to the outer wall of the bidirectional threaded rod 5, and the bidirectional threaded rod 5 is connected to the drive motor 9. At the same time, the two moving sliders 6 are connected to the fixed plate 8 through the first connecting plate 7. At this time, the operation of the drive motor 9 can drive the bidirectional threaded rod 5 to rotate, so that the two moving sliders 6 move relative to each other, and finally drive the two fixed plates 8 to move relative to each other to clamp and fix the chassis, which can ensure the accuracy and stability of welding. Therefore, it helps to reduce the rework phenomenon caused by welding defects and improve production efficiency. Secondly, two anti-slip pads 10 are provided on the top of the support frame 1, which can reduce the frictional wear when the chassis is in direct contact with the support mechanism, and extend the service life of the chassis and the support mechanism. Secondly, by aligning the holes on the chassis with the positioning holes 12 on the top of the support frame 1 and then inserting the positioning pins 13 into the positioning holes 12 to fix the chassis, it can quickly and accurately guide the chassis components into the predetermined position, reduce the adjustment time and labor cost, and improve the welding efficiency. Secondly, two mechanical grippers 16 are fixedly installed on the top of each of the two second connecting plates 15. The mechanical grippers 16 usually have the functions of quick clamping and releasing, which can significantly shorten the fixing and disassembling time of the chassis and improve the efficiency of the welding operation. Secondly, a pressure sensor 17 is provided on the top of one second connecting plate 15, and a displacement sensor 18 is provided on the other second connecting plate 15. Both the displacement sensor 18 and the pressure sensor 17 are connected to the controller 11. The accurate measurement of displacement by the displacement sensor 18 helps to reduce the welding defects caused by position deviation. At the same time, the pressure sensor 17 cooperates with the controller 11. By accurately controlling the pressure during the welding process, the excessive impact and wear on the chassis can be reduced, thereby extending the service life of the chassis.
