[0002] When welding an electric vehicle frame production seat and an electric vehicle frame accessory, it is necessary to fix the electric vehicle frame production seat in advance to ensure stable welding of the electric vehicle frame production seat and the electric vehicle frame accessory.

[0003] At present, most electric vehicle frame production seats are mainly composed of an H-shaped rod frame. Before welding, this kind of electric vehicle frame production seat is mainly fixed by manual screwing and lifting by workers. Although the method of manual lifting and screwing can achieve the fixation of the electric vehicle frame production seat before welding, on the one hand, the operation process of manual screwing and fixing is relatively cumbersome, and the fixing efficiency is relatively low, which is not conducive to the efficient welding between the electric vehicle frame production seat and the electric vehicle frame accessory. On the other hand, manually lifting the electric vehicle frame production seat will also cause a large labor intensity for workers. Summary of the Utility Model

The jacking mechanism includes a top plate arranged above the support and electric telescopic rods installed between the four corners of the top plate and the upper end of the support. The clamping mechanism includes a double-shaft motor installed in the middle of the inner top end of the support, screws installed on the two power output shafts of the double-shaft motor, linkage plates installed on each screw, linkage rods installed in the middle of the side wall of each linkage plate facing away from the double-shaft motor, clamping plates installed at the top ends of the linkage rods, and sliding rods installed below the double-shaft motor and passing through the linkage plates.

[0017] By adopting the above technical solution, the slide rod can ensure the stable sliding of the linkage plate, and placing the screw, the linkage plate and the screw under the support can also avoid damage to the clamping structure by high-temperature welding slag during the welding process.

[0018] Furthermore, an operation panel is installed on one side wall of the support, and the operation panel is electrically connected to both the electric telescopic rod and the double-shaft motor.

[0019] By adopting the above technical solution, the operation panel mainly controls the orderly operation of the electric telescopic rod and the double-shaft motor by controlling the on-off of the circuit.

[0020] (III) Beneficial Effects

[0021] The present utility model has the following beneficial effects compared with the prior art:

[0022] To solve the problem that most current electric vehicle frame production seats are mainly composed of an H-shaped rod frame. Before welding, this type of electric vehicle frame production seat is mainly fixed by manual screwing and lifting by workers. Although the method of manual lifting and screwing can achieve the fixation of the electric vehicle frame production seat before welding, on the one hand, the operation process of manual screwing and fixation is relatively cumbersome, and the fixation efficiency is relatively low, which is not conducive to the efficient welding between the electric vehicle frame production seat and the electric vehicle frame accessories. On the other hand, manually lifting the electric vehicle frame production seat will also cause a large manual labor intensity.

[0028] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] As Figures 1 - 3As shown in the figure, a welding and fixing device for an electric vehicle frame production seat in this embodiment includes a support 2. In the middle of the top end of the support 2, a lifting mechanism 1 is installed. At the inner top end of the support 2, a clamping mechanism 4 is installed. The lifting mechanism 1 includes a top plate 102 arranged above the support 2 and electric telescopic rods 101 installed between the four corners of the top plate 102 and the upper end of the support 2. The clamping mechanism 4 includes a double-shaft motor 405 installed in the middle of the inner top end of the support 2, screw rods 406 installed on the two power output shafts of the double-shaft motor 405, linkage plates 403 installed on each screw rod 406, linkage rods 402 installed in the middle of the side walls of the linkage plates 403 facing away from the double-shaft motor 405, clamping plates 401 installed at the top ends of the linkage rods 402, and sliding rods 404 installed below the double-shaft motor 405 and passing through the linkage plates 403. The clamping wall of the support 2 is of an arc structure. The electric telescopic rods 101 drive 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 the same as the height of the clamping plates 401. The sliding rods 404 can ensure the stable sliding of the linkage plates 403, and placing the screw rods 406, linkage plates 403, and screw rods 406 below the support 2 can also avoid damage to the clamping structure by high-temperature welding slag during the welding process.

[0030] As Figures 1 - 3 shown in the figure, in this embodiment, the fixing 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 of an I-shaped structure, and the length of the top plate 102 is greater than the length of the clamping plate 401. Such a design can avoid obstruction to the clamping of the clamping plate 401 by the top plate 102 after the electric vehicle frame production seat is lifted. The double-shaft motor 405 is bolted to the support 2, the double-shaft motor 405 is connected to the screw rod 406 by a coupling, and the screw rod 406 is rotatably connected to the support 2. After the double-shaft motor 405 is started, the two screw rods 406 will rotate.

[0031] As Figures 1 - 3 shown in the figure, in this embodiment, the screw rod 406 passes through the linkage plate 403 and is threadedly connected to the linkage plate 403. The sliding rod 404 is welded to the support 2. After the screw rod 406 rotates, the two clamping plates 401 will approach each other under the action of screw thread transmission to realize the clamping and fixing of the electric vehicle frame production seat. The sliding rod 404 passes through the linkage plate 403 and is slidably connected to the linkage plate 403. The linkage rod 402 is welded to the linkage plate 403, and the linkage plate 403 passes through the side wall of the support 2 and is welded to the side wall of the support 2.

[0032] As Figures 1 - 3 shown in the figure, in this embodiment, an operation panel 3 is installed on one side wall of the support 2. The operation panel 3 is electrically connected to both the electric telescopic rod 101 and the double-shaft motor 405. The operation panel 3 mainly controls the orderly operation of the electric telescopic rod 101 and the double-shaft motor 405 by controlling the on-off of the circuit.

[0033] The specific implementation process of this embodiment is as follows: When in use, first place the electric vehicle frame production seat to be welded on the top plate 102, and under the action of the electric telescopic rod 101, lift the electric vehicle frame production seat to the height where the clamping plate 401 is located. Then start the double-shaft motor 405 to rotate the screw rod 406. After the two screw rods 406 rotate, the two clamping plates 401 will approach each other, thereby realizing the clamping and fixing of the electric vehicle frame production seat. Since in the above clamping and fixing method, the lifting and clamping and fixing processes of the electric vehicle frame production seat are both automatically realized, it not only saves the cumbersome operation of manually lifting when fixing the electric vehicle frame production seat, making the manual labor intensity smaller, but also avoids the cumbersome operation of manually screwing and fixing when fixing the electric vehicle frame production seat, making the fixing efficiency of the electric vehicle frame production seat higher, and facilitating the efficient welding between the electric vehicle frame production seat and the electric vehicle frame accessories.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
