During the assembly process, the automatic adjusting nut 11, the connecting bolt 12, the bearing seat 13, the washer 14, the bearing 15, and the spring 16 are installed in sequence inside the housing 10, and finally the retaining spring 17 is pressed into the upper part of the housing 10, so that the elastic arms 171 on both sides of the retaining spring 17 are pressed into the corresponding reserved limit grooves 101 on both sides of the axial direction of the housing 10, thereby completing the installation of the self-adjusting screw. The solution provided in the present application is developed for the above process.

[0043] See also Figures 3 to 9 , which is a caliper self-adjusting screw assembly fixture as the best embodiment of the utility model, comprises:

[0044] The support frame 20 includes a rectangular top plate 21 and a bottom plate 22 which are arranged opposite to each other in the upper and lower directions, and two columns 23 connected between the top plate 21 and the bottom plate 22. A holder 24 for fixing the self-adjusting screw is provided at the upper end of the bottom plate 22, wherein the upper end of the holder 24 is recessed downward to form a positioning groove 241 adapted to the housing 10, a slot 242 corresponding to the connecting bolt 12 is provided in the middle of the positioning groove 241, and a positioning protrusion 243 is further provided in the positioning groove 241 to facilitate adaptation to the corresponding positioning hole at the bottom of the housing 10, and hollow grooves 244 communicating with the outside are further provided on both sides of the positioning groove 241, and after the self-adjusting screw is placed, the installation position of the elastic arm 171 is opposite to the position of the hollow groove 244;

[0045] The pressing mechanism 30 includes a buckle pressing group 31 movably disposed just above the card seat 24 and a first driving device 32 disposed on the top plate 21 and used to drive the buckle pressing group 31 to move closer to or away from the card seat 24;

[0046] The lateral limiting mechanism 40 includes two groups of limiting units 50 symmetrically arranged on both sides of the card seat 24, and the limiting units 50 include a limiting block 51 for the elastic arm 171 of the horizontal limiting spring 17 to prevent it from retreating, and a second driving device 52 for driving the limiting block 51 to move toward or away from the card seat 24;

[0048] The second control switch 70 is used to control the second driving device 52 to drive the limiting block 51 to move.

[0049] Specifically, Figure 3 , 5As shown in Figures 6 and 7, the buckle pressing group 31 includes a mounting base 33 and a limiting sleeve 34, one end of the mounting base 33 is connected to the output end of the first driving device 32 and the other end thereof forms a slot 331 for accommodating the bottom of the retaining spring 17, the limiting sleeve 34 includes a limiting ring 341 arranged on the side of the slot 331 and a plurality of limiting pieces 342 extending along the side of the limiting ring 341 toward a direction away from the mounting base 33, and a yield area 343 adapted to the elastic arm 171 of the retaining spring 17 is formed between adjacent limiting pieces 342. In this embodiment, the yield area 343 can facilitate the passage of the elastic wall, thereby achieving the effect of smoothly buckling into the limiting slot 101 of the shell 10 after the buckle pressing group 31 is pressed down.

[0050] Preferably, Figure 6 , 7 As shown, the mounting groove is composed of a number of annular substrates 332 distributed at equal intervals, and a clearance gap 333 is formed between adjacent substrates 332 for the elastic arm 171 to pass through. In this embodiment, a total of four substrates 332 are provided, and the other two hollow areas formed between the substrates 332 form a fixed gap 334. The two sides of the retaining spring 17 are integrally bent to form a limiting portion 172 that cooperates with the fixed gap 334 to limit the position, thereby facilitating the installation and fixation of the retaining spring 17 in the buckle pressing group 31, and facilitating the subsequent pressing installation of the retaining spring 17.

[0052] Preferably, Figure 8 , 9As shown, the bottom plate 22 is symmetrically provided with mounting plates 221 on both sides of the card seat 24, and the two second driving devices 52 are arranged on the side where the two mounting plates 221 are close to each other.

A second waist-shaped hole 222 for the second guiding mechanism 53 to pass through is opened on the mounting plate 221, and the width of the second waist-shaped hole 222 is consistent with the outer diameter of the second guiding mechanism 53. Therefore, the second guiding mechanism 53 is horizontally guided and limited by the second waist-shaped hole 222, so that it can slide stably horizontally, so that the horizontal movement of the limiting block 51 is limited and guided by the second guiding mechanism 53, so that the process of horizontal movement of the limiting block 51 to the fixed position of the elastic wall is more stable and controllable.

[0053] Preferably, Figure 8 , 9 As shown, an arc groove 511 adapted to the outer shape of the shell 10 of the self-adjusting screw is provided on one side of the limit block 51 close to the base 24. The limit block 51 driven by the second drive device 52, in conjunction with the arc groove 511 designed thereon, can precisely fit the outer shape of the shell 10 of the self-adjusting screw, thereby ensuring precise control of the position and posture of the self-adjusting screw during the assembly process and preventing assembly deviation.

[0054] Preferably, Figure 8 As shown, two columns 23 are provided between the top plate 21 and the bottom plate 22, and the two columns 23 are staggered with respect to both sides of the mounting plate 221. The support frame 20 adopts the structural design of the top plate 21, the bottom plate 22 and the columns 23, which enhances the overall stability and load-bearing capacity of the fixture, ensuring that it can maintain a good working state even under high-load working conditions.

[0055] Preferably, the first control switch 60 and the second control switch 70 are both pneumatic switches and are arranged at the upper end of the top plate 21. The first drive device 32 and the second drive device 52 are both cylinders. This embodiment uses pneumatic switches to control the first drive device 32 and the second drive device 52, so that the operator can control the entire assembly process simply and quickly, reducing the difficulty of operation and improving work efficiency.

[0058] In addition, the design of the limiting sleeve 34, especially the existence of the clearance area 343, can adapt to different sizes of retaining springs 17, increase the versatility of the fixture, and reduce the frequency of fixture replacement due to product changes.

[0059] In addition, the support frame 20 adopts a structural design of a top plate 21, a bottom plate 22 and columns 23, which enhances the overall stability and load-bearing capacity of the fixture, ensuring that it can maintain a good working condition even under high-load working conditions.

[0060] In summary, the caliper self-adjusting screw assembly fixture realizes efficient, accurate and flexible assembly operations by integrating automated control and precision mechanical design, which plays a significant role in improving production efficiency and ensuring product quality.
