[0071] In order to be more accurate for angle positioning; as Figure 5 , Figure 6As shown, one side of the top pressing seat 43 is provided with a positioning cylinder, a positioning hole 29 matched with the positioning cylinder is formed on the outer wall of the circumference of the mounting disc 30, a jacking post 27 is installed in the positioning hole 29, a pressure sensor assembly 40 is fixed in the positioning cylinder, a sliding block 42 is slidably connected in the positioning cylinder, and the sliding block 42 and the pressure sensor assembly 40 are connected through a spring 41; the position of the sliding block 42 is matched with the jacking post 27; the mounting seat 23 is provided with an adjusting part for adjusting the relative position of the linkage frame 33 and the top pressing seat 43;

[0072] The pressure sensor assembly 40 is connected with a control module, and the control module is connected with the electric telescopic rod 24;

[0073] Through the setting of the positioning cylinder and the like, the electric telescopic rod 24 can drive the structure to move, the positioning cylinder is inserted into the corresponding positioning hole 29 while the mounting disc 30 rotates, the purpose of accurate positioning is achieved, and the machining precision is improved.

[0074] In order to better control the operation of the structure, after the adjusting cylinder is inserted into the positioning hole 29, the jacking post 27 limits the sliding block 42, the spring 41 is compressed, the value detected by the pressure sensor assembly 40 is transmitted to the control module, and after exceeding the threshold value, the control module controls the electric telescopic rod 24 to stop working; the control mode is only one control ring, and the specific implementation mode can refer to the prior art, which will not be described here.

[0077] By setting the movable frame 46, the connecting part and other structures, when the top pressing seat 43 moves towards the carrier 2, the top rod 25 is located in the second groove 52, at this time the slide bar 53 is limited and cannot move; as the top pressing seat 43 moves, the top rod 25 contacts the mounting disc 30 and is reversely extruded, at this time the top rod 25 slides in the top pressing seat 43 until the position of the first groove 45 matches the slide bar 53, the limiting effect on the slide bar 53 is removed, at this time based on the force of the side spring 51, the slide bar 53 slides to one side, the friction between the linkage frame 33 and the mounting disc 30 is reduced, and the phenomenon that the friction between the linkage frame 33 and the mounting disc 30 is too large to cause jamming when the positioning cylinder is inserted into the positioning hole 29 is avoided; since the width of the first groove 45 is greater than the width of the slide bar 53, during the movement of the slide bar 53, the top rod 25 can still slide in the top pressing seat 43 to cooperate with the insertion of the positioning cylinder into the positioning hole 29, so that the structure is not stuck; since the limiting wheel 50 is arranged, when the electric telescopic rod 24 controls the structure to reset, the limiting wheel 50 can extrude the linkage frame 33 towards the top pressing seat 43, so that the position of the second groove 52 matches the top rod 25 again, and based on the force of the movable frame spring 44, the structure can be restored for the next position adjustment.

[0078] In order to conveniently adjust the position of the linkage frame 33, as shown in Figures 5-7 The adjusting part comprises an electric lifting rod 22, the electric lifting rod 22 is installed on the mounting seat 23, the output end of the electric lifting rod 22 is fixed with a rubber wheel frame 48, one side of the rubber wheel frame 48 is installed with a position adjusting motor 37, the output end of the position adjusting motor 37 is drivingly connected with an anti-skid rubber wheel 38; a sliding groove is arranged in the sleeve frame 36, the linkage frame 33 is slidingly connected in the sliding groove of the sleeve frame 36, a vertical column 34 is fixed to the top of the linkage frame 33, a rack plate 35 is slidingly connected to the outer side of the vertical column 34, the rack plate 35 and the linkage frame 33 are connected through a vertical column spring 47, one side of the rack plate 35 is installed with a strip plate 39, the position of the strip plate 39 matches the anti-skid rubber wheel 38, the top inner wall of the sleeve frame 36 is provided with a clamping tooth matching the rack plate 35, and the rack plate 35 is engaged with the clamping tooth based on the force of the vertical column spring 47.

[0084] ①Adjustable, the position of the linkage frame 33 can be adjusted at any time, so that the final angle of the mounting disc 30 can be changed, not only by the anti-skid rubber wheel 38 and the like, but also by manually pressing the rack plate 35, so that manual adjustment can be realized, and the manual adjustment does not need to adjust the equipment program, so that different processing can be realized; for example, in a batch of work orders, individual riveting piece processing of other work orders is temporarily inserted, and the like;
