[0055] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0056] like Figure 1 、 Figure 2 and Figure 4 As shown, a YZ motion module mechanism of a riveting center includes a Y-axis module and a Z-axis module. The Y-axis module includes a Y-axis base 1 and a Y-axis drive mechanism 2. The Y-axis drive mechanism 2 is arranged on the Y-axis base 1 to drive the Z-axis module to move along the Y-axis direction.

[0057] The Z-axis module includes a lift base 5, a lift plate 6, and a lift drive mechanism 7. The lift base 5 slides on the Y-axis base 1, along the Y-axis. The lift plate 6 slides on the lift base 5, along the Z-axis. The lift drive mechanism 7 is mounted on the lift base 5 and connected to the lift plate 6 to drive the lift plate 6 up and down along the Z-axis.

[0058] In the YZ motion module mechanism of the riveting center, the Y-axis module and the Z-axis module are the main structures. The Y-axis module carries the Z-axis module, and the Z-axis module has a jig frame or a plate jig. The lifting seat 5 slides with the Y-axis base 1 along the Y-axis direction, and the lifting plate 6 slides with the lifting seat 5 along the Z-axis direction. Driven by the Y-axis drive mechanism 2 and the lifting drive mechanism 7, it can move arbitrarily along the Y-axis direction and the Z-axis direction, so that the jig frame or the plate jig can move automatically, such as automatically finding the riveting hole position. The use of the YZ motion module mechanism of the riveting center can conveniently and quickly improve the automation performance of the equipment, thereby improving the riveting efficiency.

[0059] In some embodiments of the Y-axis module, the Y-axis module further includes a Y-axis sliding component 3, such as Figure 2As shown, the Y-axis sliding assembly 3 includes a Y-axis guide rail 31 and a Y-axis slider 32. The Y-axis guide rail 31 is arranged on the Y-axis base 1 along the Y-axis direction, and the Y-axis slider 32 is slidably arranged on the Y-axis guide rail 31. The lifting base 5 is arranged on the Y-axis slider 32. The lifting base 5 utilizes the sliding cooperation between the Y-axis slider 32 and the Y-axis guide rail 31 to form a sliding cooperation between the lifting base 5 and the Y-axis base 1. Compared with the lifting base 5 directly slidingly cooperating with the Y-axis base 1, the Y-axis sliding assembly 3 has a better sliding effect, lower sliding damping, and a more stable sliding trajectory, which can effectively improve the movement accuracy of the lifting base 5.

[0060] Further, if Figure 3 As shown, the Y-axis base 1 is provided with a guide rail groove 11 and a locking groove 12 located on one side of the guide rail groove 11. The width of the Y-axis guide rail 31 is greater than that of the guide rail groove 11, and the Y-axis guide rail 31 is disposed within the guide rail groove 11. The Y-axis module also includes a pressure block 4, which is disposed within the locking groove 12 and abuts against the Y-axis guide rail 31.

[0061] The width of the Y-axis guide rail 31 is greater than the width of the guide rail groove 11. When the Y-axis guide rail 31 is placed in the guide rail groove 11, the Y-axis guide rail 31 extends laterally beyond the guide rail groove 11. When the pressure block 4 is installed in the locking groove 12, the pressure block 4 abuts the side of the Y-axis guide rail 31. By abutting the Y-axis guide rail 31 with the pressure block 4, the extrusion can be limited and the Y-axis guide rail 31 can be locked. In this way, when fixing the Y-axis guide rail 31, the Y-axis guide rail 31 can be effectively and accurately positioned and locked, thereby improving the assembly accuracy of the Y-axis.

[0062] Furthermore, the side of the locking groove 12 away from the guide rail groove 11 is a first inclined surface, and the normal of the first inclined surface is facing obliquely upward. The side of the pressure block 4 away from the Y-axis guide rail 31 is a second inclined surface, and the second inclined surface is adapted to the first inclined surface. When the pressure block 4 is locked, the first inclined surface guides the pressure block 4 to press the Y-axis guide rail 31. In order to improve the pressing effect of the pressure block 4 on the guide rail, in this embodiment, two inclined surfaces are provided, wherein the first inclined surface is located on the side wall of the locking groove 12, and the second inclined surface is located on the side wall of the pressure block 4. The angle formed by the first inclined surface and the bottom of the locking groove 12 is greater than 90 degrees. Under the guidance of the first inclined surface, the pressure block 4 presses or locks the Y-axis guide rail 31.

[0063] In some embodiments of the lifting seat 5, such as Figure 4 、 Figure 5 As shown, the lifting base 5 includes a base body 51 and a motor mounting base 52. The upper and lower portions of the base body 51 are provided with an upper bearing seat 511 and a lower bearing seat, respectively. Mounting portions 512 are provided on either side of the upper bearing seat 511. The two mounting portions 512 are provided on either side of the motor mounting base 52. In this embodiment, the motor assembly structure and the base body 51 are provided as two separate structures. This allows the motor to be assembled to the motor mounting base 52 first, and then to be assembled to the base body 51, facilitating assembly and disassembly of the motor.

[0064] Further, if Figure 5 As shown, the upper side or lower side of the mounting portion 512 is provided with a locking hole 513. Locking portions extending toward the upper side or lower side of the mounting portion 512 are provided on both sides of the motor mounting base 52, and the locking portions are provided with elongated holes 521 corresponding to the locking holes 513. Locking portions are provided on both sides of the motor mounting base 52, extending toward the upper side or lower side of the mounting portion 512 and extending at least to the position where the locking holes 513 are located. The locking portions are connected to the mounting portion 512 through a locking connection, thereby locking the motor mounting base 52. More importantly, the length of the elongated holes 521 can be used to adjust the fixed position of the motor mounting base 52 and the distance between the lifting motor and the lifting screw, thereby adapting to the transmission distance of the belt drive group described below.

[0065] Furthermore, if Figure 5 As shown, adjustment holes 522 extending toward the mounting portion 512 are provided on both sides of the motor mounting base 52. Adjustment screws are provided in the adjustment holes 522. The adjustment screws abut against the mounting portion 512 to adjust the position of the elongated hole 521. When the elongated hole 521 is used to adjust the position of the motor mounting base 52, a precise adjustment structure is lacking. In this embodiment, adjustment holes 522 are provided on both sides of the motor mounting base 52, and adjustment screws are provided in the adjustment holes 522. By abutting the mounting portion 512 with the adjustment screws, the distance between the motor mounting base 52 and the mounting portion 512 is changed, or in other words, the position of the elongated hole 521 relative to the locking hole 513 is changed, thereby more accurately adjusting the distance between the lifting motor and the lifting screw.

[0066] In some embodiments of the lifting drive mechanism 7, the lifting drive mechanism 7 includes a lifting motor, a belt transmission group, a lifting nut, a lifting screw and a lifting drive block. The lifting screw is vertically arranged in the lifting seat 5, and the lifting screw is rotatably arranged in the lifting seat 5. Specifically, two screw seats are provided in the lifting seat 5, and the two ends of the lifting screw are rotatably connected to the two screw seats respectively. The lifting motor is arranged on the lifting seat 5, and the lifting motor is connected to the lifting screw through the belt transmission group. The lifting nut is arranged on the lifting screw. One end of the lifting drive block is connected to the lifting nut, and the other end of the lifting drive block is connected to the lifting plate 6 to drive the lifting plate 6 to perform lifting and lowering movements. In this embodiment, the lifting motor outputs power, and transmits power to the lifting screw through the belt transmission group. The lifting screw is connected to the lifting plate 6 through the lifting nut, and drives the lifting plate 6 to perform lifting and lowering movements through the lifting nut.

[0067] The belt transmission group includes two pulleys and a transmission belt. The two pulleys are respectively arranged on the end of the lifting screw rod and the output shaft of the lifting motor, and the transmission belt is wound around the two pulleys.

[0068] In some examples of the Y-axis drive mechanism 2, such as Figure 2 As shown, the Y-axis drive mechanism 2 includes a Y-axis motor 21, a Y-axis screw rod 22, a Y-axis nut 23, a Y-axis motor 21 seat and a Y-axis screw rod 22 seat. The Y-axis motor 21 seat and the Y-axis screw rod 22 seat are arranged on the Y-axis base 1. The two ends of the Y-axis screw rod 22 are rotatably arranged on the Y-axis motor 21 seat and the Y-axis screw rod 22 seat respectively. The Y-axis motor 21 is arranged on the Y-axis motor 21 seat, and the Y-axis motor 21 is also connected to the Y-axis screw rod 22. The Y-axis nut 23 is arranged on the Y-axis screw rod 22, and the Y-axis nut 23 is also connected to the lifting seat 5 to drive the lifting seat 5 to move along the Y-axis. The Y-axis motor 21 drives the Y-axis screw rod 22 to rotate, and the Y-axis screw rod 22 rotates, driving the Y-axis nut 23 to move, and the Y-axis nut 23 drives the lifting seat 5 to move along the Y-axis direction.

[0069] The lifting plate 6 is slidably arranged on the lifting seat 5. Specifically, Figure 4 As shown, the Z-axis module also includes a Z-axis sliding assembly 8, which includes a Z-axis guide rail and a Z-axis slider. The Z-axis guide rail is arranged on the lifting base 5 along the Z-axis direction, and the Z-axis slider is slidably arranged on the Z-axis guide rail. The lifting plate 6 is arranged on the Z-axis slider. In this way, the lifting plate 6 can achieve sliding cooperation between the lifting plate 6 and the lifting base 5 by utilizing the sliding cooperation between the Z-axis slider and the Z-axis guide rail.

[0070] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
