DETAILED DESCRIPTION
[0019] The above solutions are further described below in connection with specific examples. It should be understood that the examples are used to illustrate the present application and are not intended to limit the scope of the present application. The implementation conditions used in the examples can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not mentioned are usually the conditions in conventional experiments.
[0020] Example 1
[0021] A hot riveting device for automobile part production, as shown in Figure 1 and Figure 2 , comprises a base 1, a limiting frame 2 connected between the upper sides of the left and right parts of the base 1, a lifting platform 3 connected to the limiting frame 2 in a sliding manner, a locking block provided on the limiting frame 2 for limiting the lifting platform 3, which is beneficial to the stability of the lifting platform 3, a workbench 4 connected to the upper side of the front part of the lifting platform 3, a hydraulic cylinder 6 installed on the limiting frame 2, a contact piece connected to the extension end of the hydraulic cylinder 6, a quick-change mechanism 5 provided on the lifting platform 3, the quick-change mechanism 5 comprising a mounting frame 52, the mounting frame 52 connected to the lifting platform 3 in a sliding manner, springs 51 connected between the mounting frame 52 and the lifting platform 3, the mounting frame 52 and the workbench 4 connected in a penetrating manner, a first motor 53 installed on the mounting frame 52, a first gear 54 connected to the output shaft of the first motor 53, a rotating platform 56 connected to the upper side of the rear part of the mounting frame 52 in a rotating manner, a second gear 55 connected to the outer side of the rotating platform 56, and the second gear 55 engaged with the first gear 54.
[0022] As shown in Figure 1 and Figure 3 , the device further comprises a cooling mechanism 7, the cooling mechanism 7 comprising a water tank, a liquid storage tank 71 connected to the base 1, liquid delivery pumps 72 installed on the left and right parts of the base 1, the liquid delivery pumps 72 connected to the liquid storage tank 71 through the liquid inlets, liquid delivery pipes 73 connected to the liquid outlets of the liquid delivery pumps 72, and liquid discharge ports 74 connected to the liquid delivery pipes 73, the liquid discharge ports 74 each provided with three leakage points, which are beneficial to the step-by-step cooling of the parts by the cooling liquid through the leakage points and the liquid discharge ports 74.
[0023] It should be noted that the hot riveting process is a process of connecting by heating rivets, which is widely used in the connection of structural parts requiring high strength and durability, and can provide high strength, durability and good sealing. In the hot riveting process, the header is a key executive component responsible for pressing the heated rivet head into the required shape. The size of the header can be adjusted to meet the actual stamping requirements. First, start the first motor 53, the output shaft of the first motor 53 rotates to drive the first gear 54 to rotate, and then drive the second gear 55 and the rotating table 56 to rotate in turn, so that the appropriate header is adjusted to the corresponding position below the contact piece. Then place the rivet on the workbench 4 so that the rivet is located at the corresponding position below the contact piece. Then start the hydraulic cylinder 6, the extension end of the hydraulic cylinder 6 drives the contact piece to move downward, the contact piece contacts the header on the rotating table 56, and the mounting frame 52 moves downward, the spring 51 is stretched, until the header contacts the rivet and performs stamping. This way can quickly adjust the specifications of the header according to actual production needs, which is beneficial to simplify the header replacement steps and improve the rivet stamping efficiency. After the stamping operation, the extension end of the hydraulic cylinder 6 drives the contact piece to reset upward, so that the contact piece is separated from the stamping of the header, and then the spring 51 is reset, and the mounting frame 52 is reset upward, so as to repeat the stamping operation. The rivet after stamping needs to be cooled and shaped. The cooling liquid in the liquid storage tank 71 can be delivered to the liquid outlet 74 through the liquid delivery pipe 73 by using the liquid pump 72. The liquid outlet 74 outputs the cooling liquid to cool the rivet. At the same time, the leakage point on the liquid outlet 74 facilitates the gradual cooling of the cooling liquid to the parts, so that the material is hardened again and restores its original mechanical properties.

A fixed table 82 is also connected to the rear side of the base 1. The lead screw 83 is threadedly connected to the lifting table 3. A limit block is provided on the lead screw 83.
[0026] It should be noted that due to the limited length of the extension end of the hydraulic cylinder 6, the stamping effect of the header may be affected. The position of the lifting table 3 can be adjusted by using the lifting mechanism 8 to enable the hydraulic cylinder 6 to drive the contact piece to better stamp. Start the second motor 81, the output shaft of the second motor 81 rotates to drive the lead screw 83 to rotate, and then drive the lifting table 3 to move, so as to adjust the lifting table 3 to the appropriate height. At the same time, the lifting table 3 and the limiting frame 2 are locked and fixed by using the locking block, so as to improve the stability of the entire device during operation.
