[0038] Reference Figures 1-4 As shown, the present application provides a holder welding machine tool, which includes a frame 1, a mounting plate 2 and a shaping mold. Among them, the shaping mold includes a fixed part 32 and a movable part 31. The movable part 31 is slidably connected to the mounting plate 2 and can move relative to the mounting plate 2 in the horizontal direction. The fixed part 32 is detachably connected to the frame 1. In the vertical direction, the mounting plate 2 can be raised and lowered relative to the frame 1 and synchronously drive the movable part 31 to be raised and lowered relative to the fixed part 32 to clamp the holder to be welded between the fixed part 32 and the movable part 31. When welding the holder to be welded, first, the holder to be welded is fixed on the movable part 31, and then the mounting plate 2 and the movable part 31 are driven to move so that the movable part 31 is close to the fixed part 32. At this time, there is an installation gap between the aforementioned fixed part 32 and the movable part 31. The holder to be welded is clamped and fixed in the installation gap, thereby ensuring the stability of the posture of the welding holder during the welding process, which is conducive to ensuring welding accuracy and welding quality. As a preferred embodiment of the present application, both the side of the movable portion 31 facing the fixed portion 32 and the side of the fixed portion 32 facing the movable portion 31 have surfaces adapted to the shape of the retaining frame to be welded. This arrangement helps to protect the surface quality and structural accuracy of the retaining frame to be welded, and prevents deformation of the retaining frame structure caused by compression between the movable portion 31 and the fixed portion 32. In addition, in the above-mentioned solution, the fixed portion 32 is detachably connected to the frame 1, and the movable portion 31 is detachably connected to the mounting plate 2. This arrangement facilitates replacement of fixed portions 32 and movable portions 31 of different specifications according to the product specifications of the retaining frame to be welded, thereby enhancing the versatility of the retaining frame welding tooling in this application.

[0039] In one example, referring to Figure 1 and Figure 3As shown, the shaping die also includes a limiting assembly, which includes a limiting protrusion 313 provided on the upper portion of the movable portion 31. The limiting protrusion 313 is engaged with the pocket of the retainer to be welded. The limiting assembly also includes a limiting hole 323 provided in the fixed portion 32. The limiting hole 323 is arranged corresponding to the limiting protrusion 313. The provision of the limiting assembly can ensure the positioning and installation accuracy of the retainer to be welded on the movable portion 31 and the matching accuracy between the movable portion 31 and the fixed portion 32, thereby facilitating welding accuracy.

[0040] As a preferred embodiment of this application, refer to Figure 1 and Figure 3 As shown, the fixing portion 32 includes a first portion 321 and a second portion 322 arranged opposite to each other in the horizontal direction, a welding zone 33 is sandwiched between the first portion 321 and the second portion 322, and the width of the welding zone 33 is greater than the width of the welding heat effect zone of the holder to be welded. Figure 1 As shown, the side of the first portion 321 facing the second portion 322 and the side of the second portion 322 facing the first portion 321 are both provided with a slope extending to the welding area 33. Figure 3 As shown, a through hole 311 corresponding to the welding area 33 is opened on the upper portion of the moving portion 31 .

[0041] In the above scheme, the provision of welding area 33 facilitates welding tools such as welding guns to approach the holder to be welded for welding operations. Furthermore, by providing slopes near welding area 33 on first portion 321 and second portion 322, the operable space for the welding tool is increased, facilitating flexible adjustment of the welding tool to better ensure welding quality. The provision of through-hole 311 on movable portion 31 allows for direct separation of movable portion 31 from the heat-affected zone of the holder to be welded, thereby preventing both high temperatures generated by welding and the structural strength of movable portion 31 from being affected. As a preferred embodiment of the present application, mounting plate 2 is also provided with a through-slot 22 corresponding to the aforementioned through-hole 311.

[0042] Continue to refer to Figure 1 As shown, the mounting plate 2 is provided with a horizontal guide portion, and the moving portion 31 is connected to the horizontal guide portion. The moving portion 31 moves along the horizontal guide portion relative to the mounting plate 2. This arrangement is conducive to ensuring the stability of the moving path of the moving portion 31 and the stability of the posture of the holder to be welded provided on the moving portion 31, thereby improving the welding quality. In a preferred example, referring to Figure 1As shown, the movable portion 31 is sleeved on the upper portion of the mounting plate 2. The edge of the mounting plate 2 is provided with a guide bar 21 extending in the horizontal direction. The guide bar 21 is the horizontal guide portion. The lower portion of the movable portion 31 is provided with a slide groove 312 that cooperates with the guide bar 21. The horizontal guide portion in this example has a simple structure and is easy to set up. While ensuring the guiding effect, it also facilitates the mating connection and disassembly between the movable portion 31 and the mounting plate 2. Of course, the horizontal guide portion can also adopt other more different structures and settings, and the movable portion 31 and the mounting plate 2 can also adopt other more different connection structures and connection methods. This application does not make specific restrictions on this.

[0043] As a preferred embodiment of the present application, the frame 1 and / or the mounting plate 2 are further provided with a horizontal limiter, which cooperates with the movable portion 31 to limit the position. The provision of the horizontal limiter helps ensure that the movable portion 31 moves horizontally in place relative to the mounting plate 2, thereby ensuring welding quality. It should be noted that the present application does not specifically limit the structure and arrangement of the horizontal limiter, and it can be adaptively adjusted according to actual installation requirements.

[0044] As a preferred embodiment of this application, refer to Figure 4 As shown, the retainer welding fixture in the present application also includes a drive assembly and a control unit 6. The drive assembly includes a first drive member 41 connected to the mounting plate 2 and a second drive member 42 connected to the moving part 31. The control unit 6 is connected to the first drive member 41 and the second drive member 42 respectively. In one example, the first drive member 41 and the second drive member 42 preferably further include a displacement monitoring member. The displacement monitoring member includes a horizontal monitoring member 51 for monitoring the horizontal movement distance of the moving part 31 and a vertical monitoring member 52 for monitoring the vertical movement distance of the mounting plate 2, and a limit monitoring member 53 provided on the horizontal limit part for monitoring the position matching between the moving part 31 and the horizontal limit part; the control unit 6 is connected to the horizontal monitoring member 51, the vertical monitoring member 52 and the limit monitoring member 53 respectively, and the first drive member 41, the second drive member 42, the horizontal monitoring member 51, the vertical monitoring member 52 and the limit monitoring member 53 are controlled in linkage through the control unit 6.

[0045] In the above solution, the provision of a displacement monitoring element helps ensure that the mounting plate 2 and the movable portion 31 are moved into position, thereby ensuring that the fixed portion 32 and the movable portion 31 can accurately secure the retainer to be welded, thereby ensuring welding quality. Combined with the provision of a control unit 6, automatic control of the movement of the mounting plate 2 and the movable portion 31 can be achieved. The control unit 6 can also be connected to the aforementioned welding tool to automatically control the welding tool, thereby greatly improving the degree of automation of the retainer welding tool in this application.
