The rotary riveting machine is generally composed of a machine body, a workbench, a power mechanism and a control part. The action mode of the rotary riveting machine is generally composed of two parts: vertical axial movement and horizontal radial movement.

[0003] The current riveting process is: take the rivet - swing the rivet - rivet, that is, the rivet is pre-installed on the workpiece manually, and then it is taken to the riveting machine for processing. After processing, it is inspected and the good products are placed in the finished product box. There are many disadvantages in this manual swing riveting and manual riveting method. When the workpiece is taken to the riveting machine for riveting, if a smaller thin plate workpiece is processed, the workpiece is held close to the pressure head of the riveting machine by hand, and it is easy to press the hand due to misoperation, which is highly dangerous. At the same time, the labor intensity is high, and the worker may forget to swing the rivet, resulting in the phenomenon of riveting the workpiece, which makes the production quality unstable. Therefore, it is particularly important to improve the existing rotary riveting device and design a new automatic rotary riveting device to change the above technical defects and improve the practicality of the overall rotary riveting device.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Example

[0021] This embodiment provides an automatic riveting device, which can clamp the workpiece when the workpiece is riveted, without the need for manual holding, and at the same time adds the function of automatic riveting, thereby improving the overall practicality of the riveting device.

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] An automatic riveting device comprises a workbench main body 1, a connecting seat 2 is fixedly connected to the top of the workbench main body 1, the connecting seat 2, the connecting seat 2 is slidably connected to two groups of connecting blocks 3 at one end away from the workbench main body 1, two groups of connecting grooves 4 are provided at the ends of the two groups of connecting blocks 3 close to each other, the connecting grooves 4 are internally rotatably connected with a rotating block 5, the rotating block 5 is provided at one end away from the connecting groove 4, a clamping piece 7 is rotatably connected to the inside of the accommodating groove 6, the connecting block 3 extends to the inside of the connecting seat 2 and a driving rack 8 is installed, and a vibrating unloading tray 9 is fixedly connected to the top of the workbench main body 1 and at one end close to the connecting seat 2.

[0024] Furthermore, a plurality of groups of buffer pads 10 are fixedly connected to one end of the clamping member 7 away from the accommodating groove 6. The buffer pads 10 are evenly spaced on the surface of the clamping member 7 and are made of rubber. When the clamping member 7 contacts the workpiece, the buffer pads 10 can increase the buffer distance between the workpiece and the clamping member 7, thereby preventing the clamping of the clamping member 7 from damaging the outer side of the workpiece and causing defects.

[0025] Among them, the two groups of driving racks 8 are connected by a driving gear 11, and a connecting rod 12 is fixedly connected to the inside of the driving gear 11. The connecting rod 12 extends from one end of the driving gear 11 to the inside of the connecting seat 2 and is fixedly connected to a driving motor. Starting the driving motor drives the driving gear 11 to rotate, so that the two groups of driving racks 8 can be displaced. The connection method between the driving rack 8 and the connecting seat 2 is a sliding connection, which can increase the stability of the displacement when the driving rack 8 is displaced.

[0026] Secondly, a movable groove 13 is provided at one end of the connecting seat 2 close to the driving gear 11, and the driving rack 8 is connected to the connecting block 3 through a connecting piece. The external structure size of the connecting piece is designed to correspond to the internal structure size of the movable groove 13. The connecting piece is passed through the movable groove 13, so that the driving rack 8 can be connected to the connecting block 3. When the driving rack 8 is displaced, the connecting block 3 can be driven to displace through the connecting piece. When the connecting block 3 contacts the workpiece, the rotating block 5 and the clamping piece 7 can rotate to fit the outside of the workpiece to clamp the workpiece, thereby eliminating the need for manual operation of the workpiece, preventing damage to workers and improving work efficiency.

[0027] Furthermore, a sliding member 14 is fixedly connected to one end of the connecting block 3 near the connecting seat 2, and a sliding groove 15 is opened at one end of the connecting seat 2 near the sliding member 14. The internal structure size of the sliding groove 15 is designed to correspond to the external structure size of the sliding member 14. The connecting block 3 is slidably connected to the sliding groove 15 through the sliding member 14. The sliding member 14 is connected to the sliding groove 15 so that the connecting block 3 can be slidably connected to the sliding groove 15. When the connecting block 3 is displaced, the sliding groove 15 can limit the sliding member 14 to prevent the connecting block 3 from being offset, which affects the clamping of the connecting block 3 on the workpiece.

[0028] Furthermore, a conveying groove 16 is provided at the top of the connecting seat 2 and at one end away from the connecting block 3, and a guide groove 17 is provided at one end of the conveying groove 16 close to the connecting block 3. A pushing piece 18 is slidably connected inside the guide groove 17, and the pushing piece 18 extends to the inside of the connecting seat 2 and is fixedly connected to an electric telescopic rod. The vibrating feed tray 9 is connected to the conveying groove 16 through a conveying frame 19, and the end of the connecting seat 2 away from the connecting block 3 is fixedly connected to a riveting machine 20. The rivet is placed inside the vibrating feed tray 9, the vibrating feed tray 9 is started, and the rivet is introduced into the conveying groove 16 through the conveying frame 19. It can be introduced into the guide groove 17 through the conveying groove 16, and the electric telescopic rod is started to drive the pushing piece 18 to move, so that the rivet can be guided to the specified position. There is no need to manually place the rivet, which can improve work efficiency. When the workpiece contacts the rivet, it can be riveted by the riveting machine 20.

[0029] In this embodiment, the implementation scenario is specifically as follows: in actual use, the rivet is placed inside the vibrating feed tray 9, the vibrating feed tray 9 is started, and it is introduced into the inside of the conveying groove 16 through the conveying frame 19, and it can be introduced into the inside of the guide groove 17 through the conveying groove 16, and the electric telescopic rod is started to drive the pushing member 18 to move, so that the rivet can be guided to the specified position, and the workpiece is placed at the specified position to contact the rivet, and the driving motor is started to drive the driving gear 11 to rotate, so that the two sets of driving racks 8 can be displaced. When the driving rack 8 is displaced, the connecting block 3 can be driven to move through the connecting member. When the connecting block 3 contacts the workpiece, the rotating block 5 and the clamping member 7 can rotate, fit the outside of the workpiece, clamp the workpiece, and perform riveting operation on it through the riveting machine 20. Compared with the existing riveting device, the utility model can improve the overall practicality of the riveting device through design.
