DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0017] Reference Figure 1A riveting device for an automobile bracket includes a press head 1, a riveting auxiliary component arranged below the press head 1, the riveting auxiliary component including a support frame 10, a support block 8 that can slide up and down is connected to the support frame 10, a conversion bracket 6 with a horizontal axis is rotatably connected to the support block 8, and the conversion bracket 6 is provided with at least two pressure heads 3 along its radial direction, and the plurality of pressure heads 3 respectively have first grooves 4 of different sizes, and a pressure-bearing component is provided below the conversion bracket 6, and the pressure-bearing component has a plurality of second grooves 21 corresponding to the first grooves 4.
[0018] When the device is in use, the rivet 13 is passed through the first bracket 14 and the second bracket 23, and the head of the rivet 13 is limited and supported in the second groove 21. Then the conversion bracket 6 is rotated to make the pressure head 3 matching the second groove 21 move to the bottom, and then the press is started to make the press head 1 move downward, and downward pressure is applied to the conversion bracket 6 through the press head 1. Under the action of pressure, the conversion bracket 6 slides downward through the support block 8, so that the pressure head 3 at the bottom of the conversion bracket 6 applies pressure to the tail of the rivet 13, so that the tail of the rivet is compressed into a shape matching the first groove 4, and the riveting work is completed. The device can easily cope with the riveting work of rivets of different sizes through one device.
[0019] As a sliding connection method, the support frame 10 is provided with a vertically arranged slide rail 9, which can be a protruding slide rail or a groove-type slide rail. The support block 8 is at least partially slidably connected to the slide rail 9. Support shafts 12 are fixedly connected or integrally formed on both sides of the conversion bracket 6, and the support shafts 12 are rotatably connected to the support block 8. Through the sliding connection between the support block 8 and the slide rail 9, and then the rotational connection between the support block 8 and the support shaft 12, it is possible to achieve both the support block 8 driving the conversion bracket 6 to move up and down and the conversion bracket 6 to rotate relative to the support block 8.
[0020] To facilitate the positioning of the conversion bracket 6, a first ball plunger 7 is fixedly mounted on the support block 8. The side of the conversion bracket 6 has a plurality of annularly distributed first positioning grooves 15, into which the ball head of the first ball plunger 7 can be inserted. Each first positioning groove 15 corresponds to a pressure position of the pressure head 3, so that the operator can better determine whether the conversion bracket 6 is rotated into place during use.
[0021] As an embodiment, the conversion bracket 6 can be a cross-shaped, a Pozigzag-shaped structure, etc., and a pressure head 3 with a first groove 4 of different sizes is fixed at each end.
[0022] The conversion bracket 6 is provided with a thread groove 5 in the circumferential direction, and the pressure head 3 has a thread head. The depth of the thread groove 5 is greater than the length of the thread head of the pressure head 3. The thread head is threadedly connected to the thread groove 5, and the stepped surface of the pressure head 3 is supported on the conversion bracket 6. In this way, an unlimited number of pressure heads 3 can be replaced and installed on the limited conversion bracket 6, further improving the applicability. In addition, the installation method in which the stepped surface of the pressure head 3 is supported on the conversion bracket 6 can avoid damage to the thread teeth due to force on the thread when pressure is applied.
[0023] As an embodiment, the press head 1 is provided with a groove cavity 2, and the pressure head 3 can be completely accommodated in the groove cavity 2. The press head 1 can directly abut against the conversion bracket 6, so that when the press head 1 applies pressure, it directly acts on the conversion bracket 6, thereby preventing the press head from damaging the pressure head 3.
[0024] The support frame 10 is located below the support block 8 and is equipped with a thrust spring 11 that can push the support block 8 upward, thereby facilitating the upward reset of the conversion bracket 6.
[0025] The pressure-bearing component includes a support seat 17 which is relatively fixed to the support frame 10. The support seat 17 is located directly below the press head 1. A limiting ring 18 is fixed to one side of the support seat 17. A limiting column 19 is rotatably connected to the limiting ring 18. A pressure-bearing bracket 20 is fixed to the top of the limiting column 19. The pressure-bearing bracket 20 is at least partially supported on the support seat 17. A second groove 21 is provided on the top surface of the pressure-bearing bracket 20 around the axis of the limiting column 19. The second grooves 21 of different sizes are replaced by rotating the pressure-bearing bracket 20 to correspond to the size of the first groove 4. In addition, with this arrangement, the force applied to the rivet 13 by the press head 1 and the conversion bracket 6 acts on the support seat 17, thereby extending the service life of the entire device.
[0026] A number of second positioning grooves 22 are provided at the bottom of the pressure-bearing bracket 20 around the axis of the limit column 19. A second ball plunger 16 is fixedly connected to the support seat 17. The ball head of the second ball plunger 16 can be inserted into the second positioning groove 22. Each second positioning groove 22 corresponds to a second groove 21. Similarly, the second ball plunger 16 and the second positioning groove 22 facilitate the positioning of the second groove 21 of the pressure-bearing bracket 20.
[0027] The above is only a preferred specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any technical solution, conception, and design obtained by equivalent replacement or modification of the technical solution and utility model concept of the present invention by any technical personnel familiar with the technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
