[0002] In today's rapidly developing automotive manufacturing industry, the production efficiency and quality of automotive parts directly impact vehicle performance and production cycles. Riveting, a key process in automotive parts assembly, is widely used for connecting and fixing body structural components, interior parts, and other components; its assembly quality is crucial to the safety and reliability of the vehicle. Traditional press-fitting equipment mostly employs a single-station operation mode, where workpiece loading / unloading and riveting operations cannot be carried out concurrently. During riveting operations, workers must wait for the work to be completed before loading / unloading, resulting in long equipment downtime and low production efficiency. Furthermore, traditional press-fitting equipment largely relies on manual loading, requiring workers to hold the rivets and, through visual inspection and manual operation, precisely place each rivet into the designated riveting hole at the workpiece's connection point. Moreover, the speed and accuracy of manual feeding are difficult to guarantee, easily leading to problems such as missed rivets, affecting workpiece quality.

[0003] Based on the above, this utility model proposes a press-fit assembly device, which can effectively solve the above problems. Utility Model Content

[0024] The working principle of one embodiment of this utility model is as follows: First, the operator places the workpiece to be riveted onto the mounting fixture 3 on the front side of the turntable 2. The support block 306, positioning post 308, and pressing sleeve 307 in the mounting fixture 3 work together to position and support the workpiece, ensuring it is in the correct posture. Next, the drive motor 4 rotates the turntable 2 180°, switching the mounting fixture 3 with the workpiece to the pressing position. Simultaneously, the mounting fixture 3 on the other side, which has already been pressed, rotates to the feeding position for loading. The three-way moving component 7 on the fixed plate 6 moves the pressing component 8 along the X, Y, and Z axes according to a preset program, precisely aligning it with the workpiece pressing position. Simultaneously, the rivets in the rivet vibrating disc 901 of the feeding assembly 9 are arranged in an orderly manner and conveyed to the rivet linear feeder 902. With the assistance of the rivet vibrator 903, the rivets are oriented and conveyed to the rivet guide plate 905. The push cylinder 907 drives the rivet guide plate 905 to slide along the slide rail 910, pushing the rivets to the rivet guide hole 914 of the rivet discharge plate 913. Then, the rivets enter the pressing box 808 of the pressing assembly 8 through the rivet discharge pipe 915 and the rivet feed pipe 810. Then, the pressing assembly 8, under the action of power, moves the pressing rod 802 downward, passing through the first fixed plate 806 and the second fixed plate 807 in sequence, pressing the rivets in the pressing box 808 out of the rivet discharge hole 809 and pressing them into the corresponding position of the workpiece. During this process, the slide bar 804 and spring 805 provide cushioning to ensure stable pressing force and avoid damage to the workpiece and rivets. The clamping cylinder 811 drives the clamping block 812 to fix the rivets before pressing, preventing them from shifting or falling off and ensuring accurate pressing. After pressing is completed, the pressing assembly 8 rises and resets, the three-way moving assembly 7 moves it back to its initial position, the drive motor 4 starts again, the turntable 2 rotates 180°, the operator removes the pressed workpiece and places a new workpiece, and the device enters the next cycle, continuously and efficiently completing the pressing and assembly work.
