In the utility model, since a concave claw is fixedly installed at the end of the connecting arm, and the left side wall of the groove of the claw is flush with the outer wall of the inner push plate, the claw and the inner push plate can cooperate to clamp one end of the I-beam. And a tension lock rod is vertically screwed through the middle part of the outer wall of the middle connecting plate through a bearing ring. The middle part of the tension lock rod passes through the connecting frame, and a pull ring is arranged at the end of the tension lock rod. By rotating the tension lock rod, the middle connecting plate can be driven to move leftward, so that the claw moves downward and cooperates with the inner push plate to bite the I-beam.

[0004] In the existing welding tooling, during the spot welding process, a clamping device is usually used. The traditional clamping device is a manually driven lead screw structure for clamping, which is very laborious, requires multi-point fixation, and the clamping is not firm. Moreover, during the spot welding process, due to the large force at the clamping end, pits and unevenness are likely to occur at the clamping part of the bottom guard plate, which further affects the processing quality of the bottom guard plate and causes economic losses. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a welding tooling for the bottom guard plate of a new energy vehicle, so as to solve the problems in the above-mentioned background technology. In the process of spot welding, clamping equipment is usually used. The traditional clamping equipment is a manually driven lead screw structure for clamping, which is very laborious, requires multi-point fixation, and the clamping is not firm. Moreover, in the process of spot welding, due to the large force at the clamping end, the clamping part of the bottom guard plate is prone to be pitted, which affects the processing quality of the bottom guard plate and causes economic losses.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions: A welding tooling for the bottom guard plate of a new energy vehicle, including a fixing device.

Special-shaped sliders are arranged at the upper and lower ends near the top and bottom of the long block. The two groups of special-shaped sliders are located at the upper and lower ends of the trapezoidal block.

[0007] Preferably, the fixing device further includes a fixed seat and an auxiliary telescopic rod. Support seats are arranged at the left and right edge positions on the upper end of the base. One end of the fixed seat is provided with a cylinder. One end of the four groups of auxiliary telescopic rods is fixed to one end of the fixed seat. One end of the cylinder is fixed to one end of the clamping plate.

[0008] Preferably, long grooves are respectively formed through the front and rear ends of the long block. The inclination angles of the upper and lower ends of the trapezoidal block are the same as the inclination angles of one ends of the two groups of special-shaped sliders. The inclination angles of one ends of the two groups of special-shaped blocks are the same as the inclination angles of the other ends of the two groups of special-shaped sliders.

[0009] Preferably, the other ends of the four groups of auxiliary telescopic rods are fixed to one end of the clamping plate. The lower end of the fixed seat is fixed to the upper end of the support seat.

[0010] Preferably, cylinders are welded at the front and rear ends of the special-shaped slider. The four cylinders are respectively movably installed inside the two long grooves.

[0011] Preferably, a triangular inclined seat is arranged on the right side of the support seat. The lower ends of the two groups of triangular inclined seats are fixed to the upper end of the base.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. In the present utility model, by providing a fixing device, starting two sets of cylinders causes them to drive the protection structure to move respectively.

[0014] 2. In the present utility model, by providing a protection structure, during the clamping process, the two protection plates are subjected to the pressure conducted by the bottom protection plate. The bottom protection plate pushes the inside of the trapezoidal seat-shaped long block. Since the inclination angles of the upper and lower ends of the trapezoidal seat are the same as those of one end of the two special-shaped sliders, when the trapezoidal seat moves to the right, it pushes the two special-shaped sliders to move. And because the inclination angles of the other ends of the special-shaped sliders are the same as those of one end of the special-shaped block, and during the movement of the special-shaped sliders, they push the special-shaped block to move to the left.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1-4 As shown: A welding tooling for the bottom guard plate of a new energy vehicle includes a fixing device 1. The fixing device 1 includes a base 11 and a protection structure 12. Two groups of protection structures 12 are located above the base 11.

[0023] The specific settings and functions of its fixing device 1 and protection structure 12 will be specifically described below.

[0024] As Figure 1 、 Figure 2 and Figure 4 As shown, the fixing device 1 further includes a fixing seat 14 and an auxiliary telescopic rod 16. Support seats 13 are arranged at the upper ends of the left and right edge positions of the base 11. One end of the fixing seat 14 is provided with a cylinder 15. One ends of four groups of auxiliary telescopic rods 16 are fixed to one end of the fixing seat 14. One end of the cylinder 15 is fixed to one end of the clamping plate 121. The other ends of the four groups of auxiliary telescopic rods 16 are fixed to one end of the clamping plate 121. The lower end of the fixing seat 14 is fixed to the upper end of the support seat 13. A triangular inclined seat 17 is arranged on the right side of the support seat 13. The lower ends of the two groups of triangular inclined seats 17 are both fixed to the upper end of the base 11.

[0025] The overall effect achieved by the entire fixing device 1 is that by setting the fixing device 1, by starting the two cylinders 15, they respectively drive the protection structure 12 to move. When the protection structure 12 moves, it will drive the four groups of auxiliary telescopic rods 16 to move accordingly, so as to be able to clamp the bottom guard plate, thus facilitating the clamping of the bottom guard plate, reducing the labor intensity of workers, and through the four groups of auxiliary telescopic rods 16 provided, when the clamping plate 121 moves, it can play a stabilizing role on the clamping plate 121, preventing the clamping plate 121 from shaking during the movement process.

[0026] As Figure 2As shown in the figure, the protection structure 12 includes a clamping plate 121 and a protection plate 122. A trapezoidal block 123 is welded at the middle position on the right side of the protection plate 122. A long block 124 is arranged on the inner right side wall of the clamping plate 121. Special-shaped blocks 125 are arranged near the upper and lower edges on the right side of the protection plate 122. Special-shaped sliding blocks 126 are arranged near the top and bottom positions inside the long block 124. The two groups of special-shaped sliding blocks 126 are located at the upper and lower ends of the trapezoidal block 123. Long grooves 127 are formed through the front and rear ends of the long block 124. The inclination angles of the upper and lower ends of the trapezoidal block 123 are the same as the inclination angles of one end of the two groups of special-shaped sliding blocks 126. The inclination angles of one end of the two groups of special-shaped blocks 125 are the same as the inclination angles of the other end of the two groups of special-shaped sliding blocks 126. Cylinders 128 are welded at the front and rear ends of the special-shaped sliding blocks 126. The four groups of cylinders 128 are respectively movably installed inside the two long grooves 127.

[0027] The effect achieved by the entire protection structure 12 is that by setting the protection structure 12, during the clamping process, the two protection plates 122 will receive the pressure conducted by the bottom protection plate, and the bottom protection plate will push the trapezoidal seat-shaped long block 124 to move inside. Since the inclination angles of the upper and lower ends of the trapezoidal seat are the same as the inclination angles of one end of the two groups of special-shaped sliding blocks 126, when the trapezoidal seat moves to the right, it will push the two groups of special-shaped sliding blocks 126 to move. And because the inclination angle of the other end of the special-shaped sliding block 126 is the same as the inclination angle of one end of the special-shaped block 125, and during the movement of the special-shaped sliding block 126, it will push the special-shaped block 125 to move to the left. Then the two groups of special-shaped blocks 125 will push the protection plate 122 to move outward, so as to further fix the bottom protection plate and reduce the clamping force on the bottom protection plate, prevent the clamped part of the bottom protection plate from being pitted, ensure the processing quality of the bottom protection plate, and thus prevent economic losses.

[0028] Working principle of the utility model: When in use, first, move the bottom guard plate above the base 11, and then start the two groups of cylinders 15 to drive the protection structure 12 to move respectively. When the protection structure 12 moves, it will drive the four groups of auxiliary telescopic rods 16 to move accordingly, so as to clamp the bottom guard plate, which is convenient for clamping the bottom guard plate, reduces the labor intensity of workers, and through the four groups of auxiliary telescopic rods 16 provided, when the clamping plate 121 moves, it can play a stabilizing role on the clamping plate 121 to prevent the clamping plate 121 from shaking during the moving process. Finally, during the clamping process, the two protection plates 122 will receive the pressure conducted by the bottom guard plate, and the bottom guard plate will push the inside of the trapezoidal seat-shaped long block 124 to move. Since the inclination angles of the upper and lower ends of the trapezoidal seat are the same as those of one end of the two special-shaped sliders 126, when the trapezoidal seat moves to the right, it will push the two special-shaped sliders 126 to move. And because the inclination angles of the other end of the special-shaped slider 126 and one end of the special-shaped block 125 are the same, and during the movement of the special-shaped slider 126, it will push the special-shaped block 125 to move to the left. Then the two special-shaped blocks 125 will push the protection plate 122 to move outward, so as to further fix the bottom guard plate and reduce the clamping force on the bottom guard plate, prevent the clamped part of the bottom guard plate from being pitted, ensure the processing quality of the bottom guard plate, and thus prevent economic losses.
