[0002] A riveting machine, also known as a riveting machine, a rotary riveting machine, a riveting machine, a rolling riveting machine, etc., is a new type of riveting equipment developed based on the principle of cold rolling. It refers to a mechanical equipment that can rivet objects together with rivets. Riveting is a riveting method that uses the static pressure generated by the riveting machine to upset the rivet rod to form an upset head. The riveted parts produced by riveting have the characteristics of good surface quality, small deformation and high connection strength.

[0003] For example, in the announcement number (CN220347114U), an automatic positioning riveting machine is disclosed in which an electrically controlled cross slide is used to change the relative position of the riveting machine and the workpiece by sliding the cross slide, so that the riveting machine is directly opposite the riveting hole of the workpiece, and fuzzy positioning is achieved by controlling the falling of the plate.

[0004] However, during the riveting process, when the rivet head is not located in the center, the rivet is squeezed and deformed, and eccentricity occurs. Therefore, an automatic positioning riveting machine that can accurately control the positioning is required.

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The present application embodiment discloses an automatic positioning riveting machine. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it includes a riveting machine 1 and an electrically controlled cross slide 2 arranged above the riveting machine 1. A connecting plate 3 is fixedly installed below the telescopic end of the riveting machine 1. Two swinging feedback components 4 with perpendicular rotation directions are fixedly installed at the bottom end of the connecting plate 3. A telescopic feedback component 5 is fixedly installed at the bottom end of the swinging feedback component 4. The workpiece is driven to move laterally through the electrically controlled cross slide 2. When it moves to the telescopic feedback component 5, the telescopic component completely falls down to generate an electrical signal. The workpiece continues to move and the telescopic feedback component 5 contacts the inner wall of the riveting hole and is squeezed and deflected. At this time, the swinging feedback component 4 generates an electrical signal, records the moving range of the two signal generation positions, and moves half of the range in the opposite direction. The electrically controlled cross slide performs lateral bidirectional movement, records the positions where the two swinging feedback components 4 generate electrical signals, and moves the workpiece to the midpoint to achieve positioning.

[0025] See also Figure 4 The swing feedback component 4 includes a connecting frame 401, which is fixedly installed below the connecting plate 3. A push switch 402 is fixedly installed on the top of the connecting frame 401. A hinge shaft 403 is elastically rotatably connected to the middle of the connecting frame 401. A rotating block 404 is fixedly installed on the outer surface of the middle of the hinge shaft 403. A protruding block 405 for squeezing the push switch 402 is arranged on the top of the rotating block 404. Through such an arrangement, when extrusion deformation occurs, the rotating block 404 rotates, and the protruding block 405 no longer squeezes the push switch 402, thereby generating an electrical signal.

[0026] See also Figure 3 The telescopic feedback component 5 includes a telescopic sleeve 501, a sliding rod 502 is slidably connected to the middle of the telescopic sleeve 501, a conductive contact 503 is fixedly installed on the outer surface of the top of the sliding rod 502, and a conductive slide 504 that slides relative to the conductive contact 503 is fixedly installed inside the telescopic sleeve 501. The sliding rod 502 extends to the outside of the telescopic sleeve 501, and a baffle 505 is fixedly installed on the outer surface of the sliding rod 502 located inside the telescopic sleeve 501. The baffle 505 and the inner wall of the telescopic sleeve 501 are fixedly connected by a reset spring 506. When the sliding rod 502 encounters a groove on the surface of the workpiece, the sliding rod 502 descends but does not separate from the conductive slide 504, so no electrical signal is generated. Only when the sliding rod 502 descends to a sufficient height at the riveting hole will an electrical signal be generated. The bottom end of the sliding rod 502 is rollingly connected to a ball 507, and the function of the ball 507 is to reduce friction

[0027] See also Figure 3 A magnetic sleeve 6 is fixedly connected between the swing feedback component 4 and the telescopic feedback component 5, and the telescopic sleeve 501 is slidably connected to the inside of the magnetic sleeve 6. An electromagnet 7 is fixedly installed on the top of the telescopic sleeve 501 and the inner top wall of the magnetic sleeve 6. The telescopic sleeve 501 and the magnetic sleeve 6 are fixedly connected by a compression spring 8. A gear ring 9 is fixedly installed at one end of the hinge shaft 403, and a motor 10 is fixedly installed on the surface of the connecting frame 401. A gear 11 that drives the gear ring 9 to rotate is fixedly installed at the output end of the motor 10. Through such an arrangement, the telescopic feedback component 5 can be retracted upward and swung to the horizontal in a large range at the same time, avoiding interference during the riveting process.

[0028] See also Figure 4 The axis of the sliding rod 502 and the axis of the rivet head of the riveting machine 1 are located on the same vertical plane, and the connecting plate 3 and the riveting machine 1 are connected by at least three bolts 12. Through such an arrangement, the difference between the original position of the device and the rivet head can be calibrated.

[0029] See also Figure 3 The sliding range of the conductive contact piece 503 is greater than the length of the conductive slide groove 504, only sliding movement occurs between the magnetic sleeve 6 and the telescopic sleeve 501, and only sliding movement occurs between the sliding rod 502 and the telescopic sleeve 501. This arrangement can avoid rotation and torsion of the spring.

[0030] The implementation principle of an automatic positioning riveting machine in an embodiment of the present application is as follows: the workpiece is driven to move laterally by an electrically controlled cross slide 2, and when it moves to the point where the telescopic feedback component 5 completely falls, an electrical signal is generated. The workpiece continues to move, and the telescopic feedback component 5 contacts the inner wall of the riveting hole and is squeezed and deflected. At this time, the swing feedback component 4 generates an electrical signal, and the moving range of the two signal generation positions is recorded, and half of the moving range is reversed. The electrically controlled cross slide performs a lateral bidirectional movement, and the positions of the electrical signals generated by the two deflections of the upper swing feedback component 4 are recorded, and the workpiece is moved to the midpoint to achieve positioning.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
