DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0026] Reference Figure 1-3 A riveting device includes a frame 1, the frame 1 includes an upper end 11 and a lower end 12, and an electric telescopic rod 2 is fixedly connected to the top of the upper end 11.

[0027] A riveting mechanism 3 is provided between the upper end 11 and the lower end 12 of the frame 1, and the riveting mechanism 3 includes a riveting piece 31 and a lower mold 32. The riveting piece 31 is fixedly connected to the telescopic end of the electric telescopic rod 2 and is located below the upper end 11. The lower mold 32 is fixedly connected to the lower end 12 of the frame 1. When the device is used, since pressure regulation and position regulation are existing technologies, no further elaboration is made. The pressure regulation is used to adjust the pressure of the riveting piece 31, and the position regulation is used to adjust the distance between the riveting piece 31 and the workpiece. The existing technology uses a pressure sensor and a displacement sensor to monitor the pressure and position of the riveting piece 31 in real time, ensuring the stability and reliability of the connection quality. When the workpiece is located on the elastic colloid 41 of the lower mold 32, the riveting piece 31 is driven downward by the electric telescopic rod 2. When the riveting piece 31 is close to the workpiece, the riveting operation is performed on the workpiece by pressure.

[0028] The outside of the lower mold 32 is provided with a mounting mechanism 5, and the mounting mechanism 5 includes a mounting block 51 and a mounting groove 52. The mounting groove 52 is opened inside the mounting block 51, and the mounting block 51 is detachably connected to the outside of the lower mold 32 through the mounting groove 52. By setting the mounting mechanism 5, the mounting block 51 and the mounting groove 52, it is beneficial to stably mount the elastic colloid 41 on the lower mold 32, thereby improving the installation and fixing effect, thereby enhancing the practicability of the device.

[0029] A connecting mechanism 8 is provided inside the mounting block 51, and the connecting mechanism 8 includes a first thread 81 and a second thread 82. The first thread 81 is provided outside the lower mold 32, and the second thread 82 is provided inside the mounting block 51. The mounting block 51 and the lower mold 32 are threadedly connected through the first thread 81 and the second thread 82. By providing the connecting mechanism 8, the first thread 81 and the second thread 82, the elastic colloid 41 can be quickly connected or disassembled with the lower mold 32 through the mounting block 51, thereby improving the practicality and thus enhancing the practicality of the device.

[0030] A positioning mechanism 7 is provided on the outside of the lower mold 32, and the positioning mechanism 7 includes an annular groove 71 and an arc block 72. The annular groove 71 is opened inside the lower mold 32, and two arc blocks 72 are provided inside the annular groove 71. The two arc blocks 72 are fixedly connected with a connecting block 73 on the side away from the lower mold 32. By setting the positioning mechanism 7, the annular groove 71, the arc block 72 and the connecting block 73, when the threaded rod 61 extends to the inside of the mounting block 51, it will push the arc block 72 to be stuck in the annular groove 71, thereby ensuring the stability of the connection between the mounting block 51 and the lower mold 32, and further ensuring the stability of the elastic colloid 41 when in use, thereby improving the practicality of the device.

[0031] The internal thread of the mounting block 51 is connected with a rotating mechanism 6, and the rotating mechanism 6 includes a threaded rod 61. Two threaded rods 61 are threadedly connected to the inside of the mounting block 51, and one end of the two threaded rods 61 is rotatably connected to the corresponding connecting block 73, and one end of the two threaded rods 61 away from the connecting block 73 extends to the outside of the mounting block 51 and is fixedly connected with a handle 62; through the rotating mechanism 6, the threaded rod 61 and the handle 62, when the elastic colloid 41 is installed on the lower mold 32 through the mounting block 51, the threaded rod 61 is rotated by the handle 62, and when the threaded rod 61 extends to the inside of the mounting block 51, a manual driving force is generated, so that the operation is simple, fast and convenient, and cost-saving, thereby improving the practicality of the device.

[0032] The outside of the mounting block 51 is fixedly connected with an anti-wear and easy-to-detach mechanism 4, which includes an elastic colloid 41 and a groove 42. The groove 42 is arranged inside the elastic colloid 41, and the elastic colloid 41 is fixedly connected to the outside of the mounting block 51 through the groove 42; by arranging the anti-wear and easy-to-detach mechanism 4, the elastic colloid 41 and the groove 42, the wear between the workpiece and the lower mold 32 can be effectively avoided, thereby increasing the service life of the lower mold 32, reducing the scrap rate of the lower mold 32, and further improving the riveting effect of the workpiece and the riveting quality of the workpiece, reducing defective products, and the elastic colloid 41 can facilitate demoulding of the workpiece. After the workpiece is riveted, it is not easy to be difficult to demould or stick. Therefore, the use effect of the riveting device is further improved, thereby improving the practicality of the device.

[0033] Working principle: When the device is used, pressure regulation and position regulation are existing technologies and are not elaborated on in detail. Pressure regulation is used to adjust the pressure of the rivet 31, and position regulation is used to adjust the distance between the rivet 31 and the workpiece. The existing technology uses pressure sensors and displacement sensors to monitor the pressure and position of the rivet 31 in real time, ensuring the stability and reliability of the connection quality. When the workpiece is located on the elastic colloid 41 of the lower mold 32, the rivet 31 is driven downward by the electric telescopic rod 2. When the rivet 31 is close to the workpiece, the rivet operation is performed on the workpiece through pressure.

[0034] By providing the anti-wear and easy-to-release mechanism 4, the elastic colloid 41 and the groove 42, the wear between the workpiece and the lower mold 32 can be effectively avoided, thereby increasing the service life of the lower mold 32, reducing the scrap rate of the lower mold 32, and further improving the riveting effect and riveting quality of the workpiece, reducing defective products, and the elastic colloid 41 can facilitate demoulding of the workpiece. After the workpiece is riveted, it is not easy to be difficult to demould or stick to the workpiece, thereby further improving the use effect of the riveting device.

[0035] The installation mechanism 5 , the installation block 51 and the installation groove 52 are provided to facilitate the elastic colloid 41 to be stably installed on the lower mold 32 , thereby improving the installation and fixing effect.

[0036] By setting the rotating mechanism 6, the threaded rod 61 and the handle 62, when the elastic colloid 41 is installed on the lower mold 32 through the mounting block 51, the threaded rod 61 is rotated by the handle 62. When the threaded rod 61 extends to the inside of the mounting block 51, a manual driving force is generated, thereby achieving the effects of simple operation, quick and convenient operation and cost saving.

[0037] By setting the positioning mechanism 7, the annular groove 71, the arc block 72 and the connecting block 73, when the threaded rod 61 extends to the inside of the mounting block 51, it will push the arc block 72 to be stuck in the annular groove 71, thereby ensuring the stability of the connection between the mounting block 51 and the lower mold 32, and further ensuring the stability of the elastic colloid 41 when in use.

[0038] By providing the connection mechanism 8 , the first thread 81 and the second thread 82 , the elastic colloid 41 can be quickly connected or disassembled with the lower mold 32 through the mounting block 51 , thereby improving practicality.
