Description

Technical Field

[0001] The invention relates to the technical field of electric vehicle production, and in particular to a welding and fixing device for a production seat of an electric vehicle frame. Background Art

[0002] When welding the electric vehicle frame production seat and the electric vehicle frame accessories, the electric vehicle frame production seat needs to be fixed in advance to ensure stable welding of the electric vehicle frame production seat and the electric vehicle frame accessories.

[0003] At present, most electric vehicle frame production seats are mainly composed of an H-shaped rod frame. The electric vehicle frame production seat of this structure is mainly fixed by workers manually twisting and lifting before welding. Although the manual lifting and twisting method can achieve the fixation of the electric vehicle frame production seat before welding, on the one hand, the manual twisting and fixing operation process is relatively cumbersome, and the fixing efficiency is relatively low, which is not convenient for efficient welding between the electric vehicle frame production seat and the electric vehicle frame accessories. On the other hand, manual lifting of the electric vehicle frame production seat will also increase the labor intensity. Summary of the invention

[0004] 1. Technical issues to be resolved The technical problem to be solved by the present invention is to provide an electric vehicle frame production seat welding and fixing device capable of automatically lifting and clamping the electric vehicle frame production seat before welding in view of the current status of the prior art.

[0005] (II) Technical solution The present invention is achieved through the following technical scheme: The present invention proposes a welding and fixing device for an electric vehicle frame production seat, comprising a support, a jacking mechanism is installed in the middle of the top end of the support, a clamping mechanism is installed in the inner top end of the support, the jacking mechanism comprises a top plate arranged above the support and an electric telescopic rod installed between the four corners of the top plate and the upper end of the support, the clamping mechanism comprises a dual-axis motor installed in the middle of the inner top end of the support, a screw rod installed on the two power output shafts of the dual-axis motor, a linkage plate installed on each of the screw rods, a linkage rod installed in the middle of the side wall of the linkage plate facing away from the dual-axis motor, a clamping plate installed at the top end of the linkage rod, and a sliding rod installed under the dual-axis motor and passing through the linkage plate, and the clamping wall of the support is an arc structure.

[0006] Furthermore, the fixing portion of the electric telescopic rod is connected to the support bolt, and the telescopic portion of the electric telescopic rod is connected to the top plate bolt.

[0007] By adopting the above technical solution, the electric telescopic rod drives the top plate to lift, and the electric vehicle frame production seat placed on the top plate can be lifted to ensure that the height of the electric vehicle frame production seat is consistent with the height of the clamping plate.

[0008] Furthermore, the top plate is an I-shaped structure, and the length of the top plate is greater than the length of the clamping plate.

[0009] By adopting the above technical solution, such a design can avoid the top plate from hindering the clamping of the clamping plate after the electric vehicle frame production seat is lifted.

[0010] Furthermore, the dual-axis motor is bolted to the support, the dual-axis motor is connected to the screw coupling, and the screw is rotationally connected to the support.

[0011] By adopting the above technical solution, the two screws will rotate after the dual-axis motor is started.

[0012] Furthermore, the screw rod passes through the linkage plate and is threadedly connected to the linkage plate, and the sliding rod is welded to the support.

[0013] By adopting the above technical solution, after the screw is rotated, the two clamping plates will be moved closer to each other under the action of thread transmission, so as to clamp and fix the production seat of the electric vehicle frame.

[0014] Furthermore, the sliding rod passes through the linkage plate and is slidably connected to the linkage plate, the linkage rod is welded to the linkage plate, and the linkage plate passes through the support side wall and is welded to the support side wall.

[0015] By adopting the above technical solution, the sliding rod can ensure the stable sliding of the linkage plate, and placing the screw, the linkage plate and the screw on the lower side of the support can also avoid damage to the clamping structure caused by high-temperature welding slag during welding.

[0016] Furthermore, an operation panel is installed on one side wall of the support, and the operation panel is electrically connected to the electric telescopic rod and the dual-axis motor.

[0017] By adopting the above technical solution, the operation panel mainly controls the orderly operation of the electric telescopic rod and the dual-axis motor by controlling the on-off of the circuit.

[0018] (III) Beneficial effects Compared with the prior art, the present invention has the following beneficial effects: In order to solve the problem that most of the current electric vehicle frame production seats are mainly composed of an H-shaped rod frame, the electric vehicle frame production seat of this structure is mainly fixed by workers manually twisting and lifting before welding. Although the manual lifting and twisting method can realize the fixation of the electric vehicle frame production seat before welding, on the one hand, the manual manual twisting and fixing operation process is relatively cumbersome, and the fixing efficiency is relatively low, which is not convenient for efficient welding between the electric vehicle frame production seat and the electric vehicle frame accessories. On the other hand, the manual lifting of the electric vehicle frame production seat will also cause the problem of high labor intensity. On the one hand, the present invention can realize the automatic lifting of the electric vehicle frame production seat when it is fixed before welding under the action of the electric telescopic rod and the top plate in the jacking mechanism, eliminating the cumbersome operation of manual lifting, so that the labor intensity is relatively low. On the other hand, it can realize the automatic clamping of the electric vehicle frame production seat under the action of the dual-axis motor, screw, linkage plate, linkage rod and clamping plate in the clamping mechanism, avoiding the cumbersome operation of manual manual twisting and fixing, and the fixing efficiency is higher, which is convenient for efficient welding between the electric vehicle frame production seat and the electric vehicle frame accessories.

The linkage rod 402 of the part, the clamping plate 401 installed on the top of the linkage rod 402, and the sliding rod 404 installed under the dual-axis motor 405 and passing through the linkage plate 403, the clamping wall of the support 2 is an arc structure, and the electric telescopic rod 101 drives the top plate 102 to lift, which can lift the electric vehicle frame production seat placed on the top plate 102 to ensure that the height of the electric vehicle frame production seat is consistent with the height of the clamping plate 401, the sliding rod 404 can ensure the stable sliding of the linkage plate 403, and the screw 406, the linkage plate 403 and the screw 406 are placed on the lower side of the support 2, which can also prevent the high-temperature welding slag from damaging the clamping structure during welding.

[0023] like Figure 1-Figure 3 As shown, in this embodiment, the fixed part of the electric telescopic rod 101 is bolted to the support 2, and the telescopic part of the electric telescopic rod 101 is bolted to the top plate 102. The top plate 102 is an I-shaped structure, and the length of the top plate 102 is greater than the length of the clamping plate 401. This design can avoid the top plate 102 from obstructing the clamping of the clamping plate 401 after the production seat of the electric vehicle frame is lifted. The dual-axis motor 405 is bolted to the support 2, and the dual-axis motor 405 is coupled to the screw 406. The screw 406 is rotatably connected to the support 2. After the dual-axis motor 405 is started, the two screws 406 will rotate.

The operation panel 3 mainly controls the orderly operation of the electric telescopic rod 101 and the dual-axis motor 405 by controlling the on-off of the circuit.
