[0022] The above technical solution allows the device to be supported by the bracket and its base.

[0023] As a further description of the above technical solution:

[0024] The top plate has sliding grooves on both the front and rear sides, and the inner side of the sliding grooves is slidably connected to the mounting plate.

[0025] The above technical solution improves the stability of the mounting plate during movement by allowing it to slide against the groove.

[0026] As a further description of the above technical solution:

[0027] The mounting plate has a groove on its outer side, and a protective pad is fixedly connected to the inner side of the groove.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 3 and Figure 4An embodiment of this utility model is provided: an automatic riveting machine, including a base 1, a U-shaped frame 3 fixedly connected to the top center of the base 1, an operating component provided on the outer side of the base 1, and a positioning mechanism 2 provided on the inner side of the base 1, the positioning mechanism 2 being used to adjust the angle of the device;

[0041] A hollow plate 4 is rotatably connected to the inner side of the U-shaped frame 3. A threaded rod 5 is rotatably connected to the inner side of the hollow plate 4. A telescopic block 6 is threadedly connected to the outer side of the threaded rod 5. A top plate 9 is slidably connected to the top of the telescopic block 6. Telescopic covers 7 are connected to the left and right sides of the top of the base 1. An arc-shaped plate 8 is fixedly connected to the top of the telescopic cover 7. The outer side of the arc-shaped plate 8 is slidably connected to the top plate 9. A rack 11 is rotatably connected to the middle of the inner side of the top plate 9. An electric gear 10 is slidably connected to the rear side of the top of the top plate 9. The rack 11 is meshed with the electric gear 10. A mounting plate 12 is fixedly connected to the top of the rack 11.

[0042] Specifically, by rotating the threaded rod 5 inside the hollow plate 4, the telescopic block 6 can be driven to move forward and backward using the principle of thread transmission. During this process, the movement of the telescopic block 6 will further drive the top plate 9 to move forward and backward synchronously, thereby completing the initial adjustment of the device. Then, the electric gear 10 is started to rotate, which will drive the rack 11 meshing with it to move left and right. As the rack 11 moves, the mounting plate 12 will also move left and right, thereby achieving precise adjustment and corresponding operation of the workpiece position on the mounting plate 12.

[0043] Reference Figure 2 , Figure 4 and Figure 5 The positioning mechanism 2 includes a threaded post 201 and a belt 204. The threaded post 201 is rotatably connected to the inner front side of the base 1. A movable plate 202 is threadedly connected to the outer side of the threaded post 201. Rotating wheels 203 are rotatably connected to the outer left and right sides of the movable plate 202. The two rotating wheels 203 are connected to each other by a belt 204. A reciprocating rod 205 is rotatably connected to the inner left and right sides of the base 1. Threaded blocks 206 are threadedly connected to the outer front and rear sides of the reciprocating rod 205. A telescopic plate 207 is rotatably connected to the inner side of the threaded block 206. The top of the telescopic plate 207 is rotatably connected to the inner front and rear sides of the telescopic cover 7.

[0044] Specifically, by rotating the threaded column 201, the movable plate 202 can be displaced, thereby causing the rotating wheel 203 on the movable plate 202 to contact the reciprocating rod 205. In this state, with the help of the transmission action of the belt 204, the two reciprocating rods 205 can be driven to rotate synchronously. As the reciprocating rods 205 rotate, the threaded block 206 on them will move accordingly, thereby causing the telescopic plate 207 to be displaced. While rotating, the telescopic plate 207 will also push the telescopic cover 7 to extend and retract according to its own telescopic characteristics, thereby realizing the adjustment of the height of the top plate 9. In addition, when the rotating wheel 203 is not in contact with the reciprocating rod 205, the angle and position of the top plate 9 can be flexibly adjusted by rotating one side of the reciprocating rod 205 alone, in conjunction with the rotation of the arc plate 8.

[0045] Reference Figure 1 , Figure 3 and Figure 5 The operating components include knob 18, two knobs 18 are rotatably connected to the left and right rear sides of the base 1 respectively, the outer side of knob 18 passes through the base 1 and is fixedly connected to the reciprocating rod 205, the front side of threaded column 201 passes through the base 1 and is fixedly connected to knob 3 20, the outer side of threaded rod 5 passes through hollow plate 4 and is fixedly connected to knob 2 19; handles 16 are provided on all four sides of the outer side of the top plate 9, and screws 17 are threadedly connected to the front and rear sides of the handles 16, and the handles 16 are threadedly connected to the top plate 9 through the screws 17; controller 21 is fixedly connected to the front side of hollow plate 4, and controller 21 is electrically connected to electric gear 10;

[0046] Specifically, rotating knob 18 can synchronously drive the reciprocating rod 205 to rotate, rotating knob 29 can synchronously drive the threaded rod 5 to rotate, the handle 16 installed by screw 17 can facilitate holding and carrying the device, and the controller 21 can control the start and rotation of the electric gear 10.

[0047] Reference Figure 1 , Figure 2 and Figure 4 The telescopic cover 7 is fixedly connected to the front and rear sides of the exterior with brackets 22, and the bottom of the brackets 22 is fixedly connected to the base 1; the top plate 9 is provided with sliding grooves 15 on the front and rear sides of the top, and the inner side of the sliding grooves 15 is slidably connected to the mounting plate 12; the mounting plate 12 is provided with a groove 13 on the outer side, and a pad 14 is fixedly connected to the inner side of the groove 13.

[0048] Specifically, the bracket 22 can support the base 1 and the telescopic cover 7 to improve their structural strength, the sliding groove 15 can improve the stability of the mounting plate 12 when moving, and the pad 14 inside the groove 13 can prevent the device from causing wear to the workpiece.

[0049] Working principle: Before using the device, firstly, by rotating the threaded rod 5 along the inner side of the hollow plate 4, the telescopic block 6 can be moved back and forth through the threaded connection. At this time, the movement of the telescopic block 6 can push the top plate 9 to move back and forth, thereby adjusting the device. Then, start the electric gear 10 to rotate, thereby driving the rack 11 meshing with it to move left and right. At the same time, as the rack 11 moves, it will push the mounting plate 12 to move left and right, thereby adjusting and operating the position of the workpiece on the mounting plate 12.

[0050] Furthermore, by rotating the threaded column 201, the moving plate 202 is pushed, causing the rotating wheel 203 on it to contact the reciprocating rod 205. At this time, the transmission of the belt 204 can synchronously drive the two reciprocating rods 205 to rotate, and with the rotation of the reciprocating rods 205, the threaded block 206 moves, and with the movement, the telescopic plate 207 moves. At this time, with the rotation of the telescopic plate 207 and its own extension and retraction, the telescopic cover 7 can be pushed to extend and retract to adjust the height of the top plate 9. At the same time, the rotating wheel 203 does not contact the reciprocating rod 205, so the angle and position of the top plate 9 can be adjusted by rotating the reciprocating rod 205 on one side and the arc plate 8.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
