Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0031] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0032] Example 1: In some embodiments, please refer to the accompanying drawings of the specification. Figures 1-4 , a servo riveting machine for processing a seat leg support, comprising a base 1;

[0033] The upper end of the base 1 is provided with a servo lift base 4, and the front end of the servo lift base 4 is provided with a telescopic rod 5 that can move up and down. The lower end of the telescopic rod 5 is provided with a rivet head 6 facing the base 1 and the rivet head 6 can rotate along its own axis. The rivet head 6 can rotate and move toward the part to be processed on the base 1;

[0034] The servo lift seat 4 is provided with a floating pre-pressing fixing mechanism 2, which is used to pre-press and fix the parts before the riveting head 6 processes the parts;

[0035] A double-station processing mechanism 3 is provided at the upper end of the base 1;

[0036] The double-station processing mechanism 3 includes a first processing assembly 31, a second processing assembly 32 and a transverse moving assembly 33. The transverse moving assembly 33 is horizontally movably arranged at the upper end of the base 1. The two sides of the moving end of the transverse moving assembly 33 are respectively provided with a first processing assembly 31 for processing the bracket and the connecting rod mechanism and a second processing assembly 32 for processing the crossbar between the bracket and the connecting rod mechanism;

[0037] In the present invention, a pressure sensing unit is provided in the servo lift base 4. The reading of the pressure sensing unit can realize the servo movement of the telescopic rod 5 at the lower end of the servo lift base 4, thereby realizing the precise control of the riveting force of the rivet head 6.

[0038] The operator can change the position of the first processing assembly 31 and the second processing assembly 32 through the lateral movement assembly 33. When the first processing assembly 31 is aligned with the rivet head 6, the leg support bracket and the connecting rod mechanism can be connected; when the second processing assembly 32 is aligned with the rivet head 6, the leg support bracket and the cross bar between the connecting rod mechanism can be connected; thus, the rivet head 6 can be used to perform the rivet operation on the entire leg support structure, effectively reducing production costs, improving production efficiency, and facilitating the operator's operation.

[0039] When the rivet head 6 rotates and moves toward the workpiece to be processed on the top of the first processing assembly 31 or the second processing assembly 32, the telescopic rod 5 will drive the floating pre-pressing fixing mechanism 2 to move downward synchronously, so that the floating pre-pressing fixing mechanism 2 can pre-press and fix the workpiece to the first processing assembly 31 or the second processing assembly 32, thereby preventing the workpiece from being shifted during the riveting operation and affecting the riveting effect, thereby ensuring the accuracy of the riveting process. In addition, the operator does not need to always hold the workpiece during the riveting operation, thereby improving the operator's convenience in operation.

[0040] The floating pre-compression fixing mechanism 2 includes a vertical moving plate 21, a sliding rod 22, a spring 23, a pressure plate 24 and a pressure block 25. The vertical moving plate 21 is fixedly connected to the telescopic rod 5, and the sliding rod 22 is symmetrically arranged on the left and right sides of the vertical moving plate 21; the lower end of the sliding rod 22 is fixedly connected to the pressure plate 24, and the upper end of the sliding rod 22 is limitedly slidably connected to the vertical moving plate 21; the outer side of the sliding rod 22 is provided with a spring 23, and the two ends of the spring 23 are respectively fixedly connected to the vertical moving plate 21 and the pressure plate 24;

[0041] The middle part of the pressing plate 24 is fixedly mounted with a pressing block 25, which is set to be conical and has a hole for accommodating the rivet head 6;

[0042] In the present invention, when the telescopic rod 5 descends, it drives the vertical moving plate 21 to move downward synchronously. Before the rivet head 6 contacts the part to be processed, the pressing plate 24 presses the part around the part to be processed against the first processing assembly 31 or the second processing assembly 32 through the pressing block 25, thereby fixing the part. As a result, the part remains stable when the rivet head 6 performs the rivet operation, thereby increasing the accuracy of the rivet operation.

[0043] The lateral movement assembly 33 includes a guide rail assembly 331, a lateral movement plate 332, a connecting block 333, a stop block 334, a socket 335 and a pin 336. The guide rail of the guide rail assembly 331 is fixedly mounted on the upper end of the base 1, and the slider of the guide rail assembly 331 is fixedly connected to the lateral movement plate 332; a connecting block 333 is provided at the front end of the lateral movement plate 332; a stop block 334 is provided on the left and right sides of the upper end of the base 1 for blocking the connecting block 333 to limit the lateral movement plate 332; corresponding sockets 335 are provided on the stop block 334 and the connecting block 333; the pin 336 is plugged into the socket 335; by pulling the lateral movement plate 332 horizontally on the guide rail assembly 331, the first processing assembly 31 and the second processing assembly 32 can be moved to the processing position below the rivet head 6, and by inserting the pin 336 into the socket 335, the position of the lateral movement plate 332 can be fixed to achieve the switching of the processing mode.

[0044] The first base plate 311 is fixedly installed on the left end of the transverse plate 332, and a first fixed block 312 is fixedly installed on the upper end of the first base plate 311, and a fixed rod 313 is fixedly installed on the upper end of the first fixed block 312. A loading hole 314 for placing rivets is opened in the fixed rod 313; after the operator places the rivet in the loading hole 314, he aligns the connecting hole of the part to be processed with the rivet in the loading hole 314 and inserts it to perform the rotary riveting process on the part.

[0045] The second processing assembly 32 includes a second base plate 321, a vertical plate 322, a second fixed block 323, a first arc groove 324, a clamping cylinder 325, a clamping block 326, a second arc groove 327 and a limiting groove 328.

[0046] The upper end surface of the second fixed block 323 is set as the first reference plane, and the upper end surface of the second base plate 321 is set as the second reference plane. When processing the cross bar, the clamping cylinder 325 drives the clamping block 326 to push toward the second fixed block 323, so that the cross bar is clamped and fixed through the first arc groove 324 and the second arc groove 327; the brackets and connecting rods at both ends of the leg support are in contact with the first reference plane and the second reference plane respectively, and the lower end of the cross bar protruding from the bracket and the connecting rod is located in the limit groove 328, and the upper end is used to cooperate with the rivet head 6 for riveting operations, thereby realizing precise processing of the cross bar of the leg support and precise positioning. At the same time, the distance between the second fixed block 323 and the clamping cylinder 325 and the second base plate 321 can fully accommodate the bracket and connecting rod of the leg support, so that they can be avoided during processing, which is convenient for the operator to operate.
