DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1-4A battery accommodating bracket welding auxiliary device includes a support platform 4 and a lifting mechanism 1 located above the support platform 4. A support frame 2 is fixed to the lifting end of the lifting mechanism 1. Four positioning components 3 are installed around the support frame 2. The positioning component 3 includes a support rod 10 vertically arranged and fixed to the side of the support frame 2. A U-shaped clamp 7 that can slide up and down is installed on the outer side of the lower part of the support rod 10. The U-shaped clamp 7 has a clamping space 8 with open outer side, upper end and lower end. A limiting cylinder component 11 is installed on the upper part of the support rod 10. The limiting cylinder component 11 has a column cavity groove 18 that can limit the surrounding sides and top surface of the limiting column 6.

[0024] refer to Figure 1 When the lifting mechanism 1 is started, the positioning assembly 3 and the four limiting columns 6 are driven downward by the support frame 2 to move downward at the same time. When the bottom end of the limiting column 6 abuts against the top surface of the bottom plate 5, the supporting frame 2 continues to move downward. The bottom end of the limiting column 6 is blocked and will slide relative to the support rod 10. As the limiting column 6 continues to slide, the upper part of the limiting column 6 is inserted into the column cavity 18, and the limiting cylinder assembly 11 is used to limit the sides and top surface of the limiting column 6, so as to achieve the purpose of simultaneously positioning the four limiting columns 6 on the bottom plate 5 and using the U-shaped clamp to complete the early clamping, thereby avoiding the problem of the limiting column 6 standing directly on the bottom plate 5 and tipping over without clamping.

[0025] The U-shaped clamp 7 includes a back plate and two side plates. The ends of the side plates have inclined surfaces. The inclined surfaces are provided to facilitate the limiting column 6 to be clamped in the clamping space 8 from the outside.

[0026] As an embodiment, the U-shaped clamp 7 is made of a metal spring sheet. The U-shaped clamp 7 has a certain elasticity, which facilitates the limiting column 6 to be clamped in the clamping space 8 from the outside.

[0027] As an embodiment, the limiting cylinder assembly 11 includes a cylinder body 17, a top plate 14 is fixed or integrally formed on the top of the cylinder body 17, a column cavity 18 is formed between the inner wall of the cylinder body 17 and the bottom wall of the top plate 14, a vertical slide rail 9 is provided on the outside of the support rod 10, and a slider 20 is provided on the side of the U-shaped clamp 7, and the slider 20 is slidably connected to the slide rail 9.

[0028] refer to Figure 2 In the natural state, the U-shaped chuck 7 is located at the bottom of the slide rail 9, and then refer to Figure 3 , insert the limit column 6 into the clamping space 8, and then move the support rod 10 downward, refer to Figure 4After the bottom end of the limiting column 6 is supported on the base plate 5, the support rod 10 continues to move downward, and the limiting column 6 is limited in the column cavity 18 inside the cylinder 17, completing the fixation of the relative position of the limiting column 6 and the base plate.

[0029] It should be noted that although the U-shaped clamp 7 can clamp the limit column 6 to prevent it from tipping over, the limit column 6 can slide in the U-shaped clamp 7 under the action of external force. For example, when the four limit columns 6 are not placed on the same horizontal plane when clamped, after the bottom end of the limit column 6 is supported on the base plate 5, when the support rod 10 continues to move downward, the limit column 6 can slide relative to the U-shaped clamp 7 to facilitate the movement of the four limit columns 6 to the same horizontal plane. Of course, when the limit column 6 is installed in the U-shaped clamp 7, the height difference between the four limit columns 6 should not exceed the depth of the column cavity 18 as much as possible.

[0030] The inner wall of the bottom end of the cylinder 17 has chamfers 19 around it. The chamfers 19 are provided to facilitate the insertion of the limiting column 6 into the column cavity 18 from bottom to top.

[0031] As another embodiment, the limiting cylinder assembly 11 includes a cylinder body 17, a top plate 14 is fixed or integrally formed on the top of the cylinder body 17, a nut 13 is welded on the outside of the top plate 14, the nut 13 is threadedly connected to the stud 12, the stud 12 passes through the bottom end of the top plate 14 and is connected to a thrust spring 15, the bottom end of the thrust spring 15 is connected to a movable plate 16, a column cavity 18 is formed between the inner circumferential wall of the cylinder body 17 and the bottom wall of the movable plate 16, a vertical slide rail 9 is provided on the outside of the support rod 10, and a slider 20 is provided on the side of the U-shaped clamp 7, and the slider 20 is slidably connected to the slide rail 9.

[0032] The limit column 6 is elastically pressed against the thrust spring 15 and the movable plate 16 to avoid the rigid pressing that may damage the service life of the lifting mechanism 1 .

[0033] The top surface of the supporting platform 4 is provided with a positioning groove for limiting the bottom plate 5 , and the positioning groove facilitates positioning of the bottom plate 5 .

[0034] The lifting mechanism 1 is an electric cylinder or an electric hydraulic cylinder in the prior art.

[0035] The above is only a preferred specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any technical solution, conception, and design obtained by equivalent replacement or modification of the technical solution and utility model concept of the present invention by any technical personnel familiar with the technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
