Description

Technical Field

[0001] This utility model mainly relates to the field of fixture technology, specifically a fixture for welding automotive parts. Background Technology

[0002] In traditional automotive parts welding processes, manual or semi-automatic welding operations mainly rely on welding rods and welding torches. This method is not only inefficient, failing to meet the demands of modern automotive manufacturing for high-efficiency production, but also prone to deviations in the welded parts due to the difficulty in ensuring perpendicularity. This often affects the overall quality and assembly accuracy of the components. Particularly in high-speed rotary welding technology, existing fixtures are prone to part displacement during welding, resulting in significant perpendicularity deviations and impacting the stability and safety of the welded parts. Therefore, a new fixture for welding automotive parts is proposed. Utility Model Content

[0003] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. It mainly provides a welding fixture for automotive parts to solve the technical problem mentioned in the background that the position of the parts held by the welding fixture is prone to shifting.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A welding fixture for automotive parts includes a rotating frustum. Several sets of first clamping mechanisms are mounted on the top of the rotating frustum, and these first clamping mechanisms are arranged in a ring. Several sets of adjusting devices are provided on the top of the rotating frustum to cooperate with the first clamping mechanisms, and these adjusting devices can drive a second clamping mechanism to move. Each first clamping mechanism includes a mounting block. Two sets of L-shaped mounting plates are slidably mounted on the top outer side of the mounting block, and a screw drive mechanism for moving the two sets of L-shaped mounting plates is installed inside the mounting block. A stop block is fixedly mounted on the inner side of each L-shaped mounting plate, and an electric telescopic rod for moving a lower pressure plate is provided on the top inner side of each L-shaped mounting plate.

[0006] Preferably, the rotating frustum includes a mounting groove, and a frustum is rotatably mounted on the top of the mounting groove, and a rotary motor for driving the frustum to rotate is disposed inside the mounting groove.

[0007] Preferably, the lead screw drive mechanism includes a bidirectional lead screw mechanism rotatably disposed inside the mounting block, and a first drive motor for driving the bidirectional lead screw mechanism to rotate is disposed on the outside of the mounting block. The bidirectional lead screw mechanism is connected to two sets of drive blocks slidably disposed inside the mounting block, and the drive blocks can drive the L-shaped mounting plate to move through the linkage block. The mounting block is provided with a moving through slot that cooperates with the linkage block.

[0008] Preferably, the abutment block and the lower pressure plate are detachably connected to an installation sleeve by bolts, and an anti-slip layer is fixedly provided on the outside of the installation sleeve.

[0009] Preferably, the adjusting device includes a mounting groove, and a positioning block is slidably connected inside the mounting groove. A screw mechanism for driving the positioning block to move is rotatably installed inside the mounting groove, and a second drive motor for driving the screw mechanism to rotate is installed on the outside of the mounting groove. One side of the positioning block is connected to a second clamping mechanism via an electric push rod.

[0010] Preferably, the second clamping mechanism has the same structure as the first clamping mechanism.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, through the cooperation of a rotating frustum and a clamping mechanism, can simultaneously clamp multiple automotive parts for welding operations, improving welding efficiency. During the clamping process, two sets of abutments can clamp and limit the parts on both sides, and the downward pressure plate can press down and position the parts again. With the combined effect of these two mechanisms, the possibility of the clamped parts moving is reduced, and the stability of the welded parts is enhanced.

On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Please refer to the appendix carefully. Figure 1-3 A welding fixture for automotive parts, wherein a rotating platform 1 is provided with a number of first clamping mechanisms 2 mounted on its top, and the first clamping mechanisms 2 are arranged in a ring. The rotating platform 1 is provided with a number of adjusting devices 3 that cooperate with the first clamping mechanisms 2, and the adjusting devices 3 can drive the second clamping mechanism 4 to move.

[0023] Specifically, the first clamping mechanism 2 includes a mounting block 201. Two sets of L-shaped mounting plates 202 are slidably disposed on the top outer side of the mounting block 201. A screw drive mechanism 5 for driving the two sets of L-shaped mounting plates 202 to move is installed inside the mounting block 201. A stop block 203 is fixedly installed on the inner side of the L-shaped mounting plate 202. An electric telescopic rod 205 for driving the lower pressure plate 204 to move is disposed on the top inner side of the L-shaped mounting plate 202.

[0024] In a further embodiment, the second clamping mechanism 4 has the same structure as the first clamping mechanism 2. The first clamping mechanism 2 clamps and limits a group of automotive parts, and the second clamping mechanism 4 clamps and limits another group of automotive parts.

[0025] In this embodiment, as Figure 1As shown, the rotating frustum 1 includes a mounting groove 101, and a frustum 102 is rotatably mounted on the top of the mounting groove 101. A rotary motor 103 is installed inside the mounting groove 101 to drive the frustum 102 to rotate. The mounting groove 101 is provided with heat dissipation holes and connection holes that cooperate with the rotary motor 103. An encoder can be installed at the output end of the rotary motor 103 to facilitate understanding the rotation angle of the frustum 102.

[0026] The above structure enables continuous welding of multiple automotive parts, which not only improves welding efficiency but also ensures that each welded part receives uniform and stable processing during the welding process. At the same time, the application of encoders makes the rotation angle controllable and adjustable, improving the automation and accuracy of the welding operation.

[0027] In this embodiment, as Figure 2 and Figure 3 As shown, the lead screw drive mechanism 5 includes a bidirectional lead screw mechanism 501 rotatably disposed inside the mounting block 201, and a first drive motor 502 for driving the bidirectional lead screw mechanism 501 to rotate is disposed on the outside of the mounting block 201. The bidirectional lead screw mechanism 501 is connected to two sets of drive blocks 503 slidably disposed inside the mounting block 201, and the drive blocks 503 can drive the L-shaped mounting plate 202 to move through the linkage block 504. The mounting block 201 is provided with a moving through slot that cooperates with the linkage block 504.

[0028] To further explain, the interior of the mounting block 201 will be cleaned periodically by moving the through groove to prevent dust and impurities from entering the mounting block 201 and affecting the operation of the bidirectional lead screw mechanism 501.

[0029] Through the above structure, the lead screw drive mechanism 5, in cooperation with the first drive motor 502 via the bidirectional lead screw mechanism 501, achieves synchronous movement control of the L-shaped mounting plate 202 and the abutment block 203. In addition, the moving through slot opened on the mounting block 201, in cooperation with the linkage block 504, further enhances the smoothness of transmission and the compactness of the structure.

[0030] In this embodiment, as Figure 3 As shown, the abutment block 203 and the lower pressure plate 204 are detachably connected to the mounting sleeve 6 by bolts, and the outer side of the mounting sleeve 6 is fixedly provided with an anti-slip layer.

[0031] With the above structure, the anti-slip layer fixed on the outside of the mounting sleeve 6 can significantly increase the friction between the sleeve and the automotive parts, effectively preventing the parts from falling off or shifting in position, ensuring welding quality. The mounting sleeve 6 is installed by means of a detachable bolt connection, which makes it easy to replace the mounting sleeve 6 when the anti-slip layer wears out later.

[0032] In this embodiment, as Figure 1As shown, the adjustment device 3 includes a mounting groove 301, and a positioning block 302 is slidably connected inside the mounting groove 301. A screw mechanism 303 that drives the positioning block 302 to move is rotatably installed inside the mounting groove 301, and a second drive motor 304 that drives the screw mechanism 303 to rotate is installed on the outside of the mounting groove 301. One side of the positioning block 302 is connected to the second clamping mechanism 4 through an electric push rod 305.

[0033] To further explain, in order to ensure the stability of the fixture in high-temperature environments, this utility model also incorporates a cooling system. The rotary motor 103, the first drive motor 502, and the second drive motor 304 are all equipped with cooling fans and heat sinks to effectively dissipate the heat generated during operation. At the same time, the key parts of the fixture are made of high-temperature resistant materials to improve the overall high-temperature resistance. The rotary motor 103, the first drive motor 502, the second drive motor 304, the electric push rod 305, and the electric telescopic rod 205 are connected to an external central control system to facilitate the synchronous control of electrical equipment in the future.

[0034] The specific operating procedure of this utility is as follows: Place the first automotive part on top of the mounting block 201 in the first clamping mechanism 2. After placement, start the first drive motor 502 to drive the bidirectional lead screw mechanism 501 to rotate. Through the drive block 503 and the linkage block 504, the L-shaped mounting plate 202 moves closer and closer to the automotive part, so that the abutment block 203 is in close contact with the side of the first automotive part for initial clamping and positioning. Then, start the electric telescopic rod 205 to push the lower pressure plate 204 down to press down the first automotive part for secondary positioning, ensuring that the first automotive part is stable and does not move.

[0035] After the above operations are completed, repeat the clamping steps of the first clamping mechanism 2, clamp the second car part through the second clamping mechanism 4, adjust the lateral position of the second car part through the electric push rod 305, start the second drive motor 304, drive the lead screw mechanism 303 to rotate, thereby causing the positioning block 302 to move vertically, adjust the longitudinal position of the second car part, so that the two car parts are stacked vertically together.

[0036] After confirming that all parts are stably clamped, start the rotary motor 103 to drive the rotary table 102 to rotate, so that the automotive parts to be processed are moved to the welding station. Use the welding equipment to weld the parts. After welding is completed, turn off the rotary motor 103. After the rotary table 102 stops rotating, release the first clamping mechanism 2 and the second clamping mechanism 4 in sequence to remove the welded parts.

[0037] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
