Then, when the shell 10 is adjusted and positioned, and the shell 10 moves between the L-shaped pressing strip 85 and the bearing frame 80 to adjust the position in the length direction, the balls on the L-shaped pressing strip 85 are used for reducing the friction force of the shell 10 during movement, and the L-shaped pressing strip 85 is also pushed by the elastic force of the return spring III 86 to always limit the shell 10 during the position adjustment of the shell 10, so that the L-shaped pressing strip 85 is prevented from being separated from the shell 10 and cannot limit the shell 10 during the positioning adjustment movement in the length direction.
Referring to fig. 3, the synchronous displacement set 87 includes a fixing bar 870 connected to an end of the L-shaped piece 94 far from the pull rod 705, the bottoms of the two opposite fixing bars 870 arranged along the width direction of the fixing table 6 are slidably connected with a T-shaped frame 871, and the T-shaped frame 871 is connected with the middle of the receiving frame 80.
When the distance between the supporting and positioning groups 70 is adjusted, the pull rod 705 drives the L-shaped piece 94 to move, the L-shaped piece 94 pulls the T-shaped frame 871 and the bearing frames 80 to move through the fixing strip 870, so that the distance between the two bearing frames 80 is synchronously adjusted along with the adjustment of the distance between the supporting and positioning groups 70, the need of independently adjusting the distance between the two bearing frames 80 is avoided, the adjustment step is simplified, and when the supporting and positioning groups 70 perform positioning adjustment on the shell 10 in the width direction, the fixing strip 870 slides along the T-shaped frame 871.
Referring to fig. 3, a balancing bar 720 is mounted on the horizontal section of the L-shaped card holder 709, the balancing bar 720 is slidably inserted through the arc-shaped side wall of the inverted U-shaped barrel 702, and the balancing bar 720 is used for supporting the L-shaped card holder 709 when the ejector rod 707 pushes the L-shaped card holder 709 to move, so as to ensure the moving stability of the L-shaped card holder 709.
When the device works, firstly, the shell 10 is placed on the clamping mechanism 8, the shaft holes 101 on the shell 10 are in one-to-one correspondence with the three supporting positioning groups 70, the two ends of the shell 10 are clamped and limited up and down through the clamping mechanism 8, and the shell 10 is prevented from moving up and down when the positioning adjusting mechanism 7 positions the shell 10 and performs tapping processing on the shell 10.
Then, the positioning adjustment mechanism 7 is used for carrying out positioning adjustment on the shell 10 in the width direction and the length direction, and the positioning adjustment mechanism 7 is used for realizing positioning adjustment on the placement position of the shell 10 through three supporting positioning groups 70, so that the accuracy of the position of the shell 10 is improved, and the tapping mechanism 4 can accurately tap the connecting hole 102 on the shell 10.
Finally, the tapping mechanism 4 is used for tapping the connecting hole 102 on the shell 10.
