Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery technology, and in particular relates to a welding mold bracket. Background Technology

[0002] Electrode welding of lead-acid batteries is a core process in the assembly and manufacturing process. Currently, the two main welding methods are manual welding and casting welding.

[0003] Manual welding offers high flexibility and adaptability, enabling the production of lead-acid batteries of various sizes and structures. Currently, manual welding remains the mainstream method for the production of larger lead-acid batteries (industrial traction batteries, energy storage batteries, marine batteries, etc.) in China.

[0004] In the normal production process of welding electrode groups for assembling larger lead-acid batteries, the welding mold box needs to be laid flat and opened first. The electrode group is then placed inside the welding mold box and closed. Then, the worker lifts the welding mold box to a vertical position and finally places it on the welding comb plate for manual welding. The above operation method is difficult to operate, the tilt angle of the welding mold box is uncontrollable, and the work efficiency is low. Utility Model Content

[0005] This utility model addresses the problems in the prior art by proposing the following technical solution: This utility model provides a welding mold box support, including: The main frame includes a bottom corner and a set of columns vertically arranged on the bottom corner. The upper end of each column is symmetrically provided with a fixed shaft extending in the horizontal direction. A C-shaped positioning frame is fixedly installed at the lower end of the column; A positioning block is fixedly installed on one of the columns. The positioning block is located on the side of the opening end of the C-shaped positioning frame, and a swing rod is rotatably installed on the top of the positioning block.

[0006] As a preferred embodiment of the above technical solution, a wrench pin is fixedly inserted into the positioning block, the wrench pin movably passes through the swing rod, the swing rod is rotatably mounted on the positioning block around the wrench pin, and both the positioning block and the swing rod are provided with insertion holes. When the swing rod rotates to the position that blocks the opening end of the C-shaped positioning frame, the two insertion holes are aligned and a positioning pin is movably inserted.

[0007] As a preferred embodiment of the above technical solution, the C-type positioning frame includes a set of side plates fixedly installed on the column, and baffles disposed between the side plates for connecting the set of side plates.

[0008] As a preferred embodiment of the above technical solution, the baffle is further provided with a stop pin, which protrudes from the opening end of the C-shaped positioning frame.

[0009] As a preferred embodiment of the above technical solution, a horizontal bar is provided between the bottom corners.

[0010] The beneficial effects of this utility model are as follows: This invention, through its main frame, C-shaped positioning frame, and movable swing arm, enables the welding mold box to switch from "tilted assembly" to "vertical welding," improving ergonomic efficiency. The movable swing arm serves both as rear support when the welding mold box is tilted during loading and as front locking during vertical welding, simplifying the structure. The C-shaped positioning frame and the swing arm work together to form a dual positioning system of "reference plane + dynamic locking," resulting in high positioning accuracy and repeatability, significantly improving welding precision, operational safety, and production efficiency.

[0012] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0013] Example like Figure 1 As shown, Figure 1 The diagram shown is a three-dimensional schematic of the bracket in the embodiment; This device includes: The main frame includes a bottom corner 10 and a set of columns 20 vertically set on the bottom corner 10. The upper end of the columns 20 is symmetrically provided with fixed shafts 21 extending in the horizontal direction. A C-shaped positioning frame is fixedly installed at the lower end of the column 20; A positioning block 41 is fixedly installed on one of the columns 20. The positioning block 41 is located on the side where the opening end of the C-shaped positioning frame is located. A swing rod 42 is rotatably installed on the top of the positioning block 41.

[0014] The bottom corner 10 serves as the basic component of the main frame, providing stable support. The upright column 20 is vertically installed on the bottom corner 10, forming the vertical support part of the main frame. A pair of upright columns 20 ensures structural symmetry and stability. The fixed shaft 21 facilitates connection with the welding mold box 1.

[0015] The C-shaped positioning frame serves two purposes: firstly, it positions the welding mold box 1, ensuring that the welding mold box 1 is in a vertical position after being placed against the C-shaped positioning frame; secondly, it reinforces the main frame.

[0016] The positioning block 41 serves as the mounting base for the swing arm 42, which forms a movable limiting mechanism that can limit or fix the welding mold box 1 after it is installed on the main frame.

[0017] like Figure 2 , Figure 3 As shown, Figure 2 The diagram shown is a schematic of the welding mold box being placed at an angle on the support in the embodiment; Figure 3 The diagram shown illustrates the welding mold box being placed vertically on the support in the embodiment. This device is used in the assembly of electrode group welding process. In the initial state, the swing rod 42 is rotated to a position that does not affect the installation of the welding mold box 1 into the inner side of the C-shaped positioning frame. Then, the two sides of the welding mold box 1 are connected to the fixed shaft 21 of the column 20, so that the welding mold box 1 can swing back and forth around the fixed shaft 21. When the welding mold box 1 is swung to an inclined state, rotate the swing arm 42 so that the swing arm 42 abuts against the rear side of the welding mold box 1. At this time, the welding mold box 1 is in an inclined state of 45° (e.g., Figure 2 (as shown in the image) In this state, open the welding mold box 1, place the electrode group into the welding mold box 1, and then close it; After the electrode group is installed, rotate the swing arm 42 to release the obstruction to the rear side of the welding mold box 1, and swing the welding mold box 1 back to the vertical position. At this time, the C-shaped positioning frame plays a positioning role for the welding mold box 1, restricting it to a vertical state. Finally, rotate the swing arm 42 and fix it, so that the swing arm 42 abuts against the front side of the welding mold box 1, fixing the vertical state of the welding mold box 1 (e.g., Figure 3 (As shown in the image), then manually weld the comb plate.

[0018] Figure 2 The position of the letter A indicates the front side of welding mold 1, and the position of the letter B indicates the rear side of welding mold 1.

[0019] The main frame of the above structure enables the welding mold box 1 to switch from "tilted assembly" to "vertical welding", improving ergonomic efficiency; the movable swing rod 42 can be used for rear support when the welding mold box 1 is tilted for loading, and for front locking when the welding mold box 1 is vertically welded, which is a dual-purpose rod and simplifies the structure; the C-shaped positioning frame and the swing rod 42 work together to form a dual positioning system of "reference plane + dynamic locking", which has high positioning accuracy and good repeatability.

[0020] like Figure 1 As shown, Figure 1 The diagram shown is a three-dimensional schematic of the bracket in the embodiment; A wrench pin 43 is fixedly inserted on the positioning block 41. The wrench pin 43 movably passes through the swing rod 42. The swing rod 42 is rotatably mounted on the positioning block 41 around the wrench pin 43. Both the positioning block 41 and the swing rod 42 are provided with insertion holes. When the swing rod 42 rotates to the position that blocks the opening end of the C-shaped positioning frame, the two insertion holes are aligned and the positioning pin 44 is movably inserted.

[0021] The wrench pin 43 serves as the rotation axis of the rocker arm 42, enabling the rocker arm 42 to rotate relative to the positioning block 41. It also features a simple structure and is easy to disassemble and maintain. When the rocker arm 42 rotates to a specific position, the two holes align, and the positioning pin 44 is then inserted to lock the position.

[0022] The C-type positioning frame includes a set of side plates 32 fixedly installed on the column 20, and baffles 31 disposed between the side plates 32 for connecting the set of side plates 32.

[0023] Side plates 32 are fixedly installed at the lower part of the two columns 20. They are usually composed of two parallel plates and serve as the side walls of the C-shaped frame, providing lateral limit and structural support. The baffle 31 is a lateral connecting plate that connects the two side plates 32, enhancing the rigidity between the side plates 32, and also serving as the back reference surface for welding the mold box 1.

[0024] The baffle 31 is also provided with a stop pin 33, which protrudes from the opening end of the C-shaped positioning frame.

[0025] The stop pin 33 achieves precise axial positioning, so that the welding mold box 1 is in a vertical position after it is against the stop pin 33.

[0026] A horizontal bar 11 is provided between the bottom corners 10.

[0027] A crossbar 11 is used to connect and fix the two bottom corners 10, forming the bottom support of the main frame, so that the main frame remains stable when placed.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
