[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 4 , the present utility model provides two technical solutions: A riveting and pressing device for casting processing, specifically including the following embodiments:

[0025] Embodiment 1: A riveting and pressing device for casting processing, including an operation table base 1. An installation groove 2 is opened at the top of the base 1. On one side inside the installation groove 2, there is a component bearing mechanism 3 for carrying the cylindrical casting to be riveted and pressed. And on one side of the installation groove 2 close to the component bearing mechanism 3, there is a power mechanism for driving the component bearing mechanism 3 to rotate intermittently. On the front of the base 1, there is a push switch 6 for controlling the switch of the power mechanism. Above the installation groove 2 and above the component bearing mechanism 3 and the power mechanism, a cover plate 7 is detachably arranged by bolts. On one side at the top of the base 1, a support frame 8 is fixedly arranged. At the top of the support frame 8, there is a riveting head unit for cooperating with the component bearing mechanism 3 to jointly complete the riveting of the casting. A circular hole is opened on one side at the top of the cover plate 7 and directly above the component bearing mechanism 3. The component bearing mechanism 3 is rotatably connected inside the circular hole, and there is no interference between the component bearing mechanism 3 and the inner wall of the circular hole. The power mechanism includes a servo motor 4 arranged at the bottom of the installation groove 2. A gear 5 fixedly arranged on the output shaft of the servo motor 4 is meshed and connected with a gear ring 32. The push switch 6 is respectively used to control the start of the servo motor 4 and the hydraulic cylinder 9. An electric motor box is fixedly arranged outside the servo motor 4, and the electric motor box is detachably installed at the bottom of the installation groove 2 by bolts. The hydraulic cylinder 9 is connected to an external hydraulic system, and the servo motor 4 is electrically connected to an external power supply. By pushing down the push switch 6, the push switch 6 can simultaneously start the hydraulic system where the hydraulic cylinder 9 is located and connect the circuit where the servo motor 4 is located. After 30 seconds, both the hydraulic system where the hydraulic cylinder 9 is located and the circuit where the servo motor 4 is located are turned off, and both the riveting head 10 and the component bearing mechanism 3 return to their original positions. The riveting head unit includes a hydraulic cylinder 9 fixedly arranged at the top of the support frame 8. A riveting head 10 is arranged on the output shaft of the hydraulic cylinder 9. The gear 5 drives the gear ring 32 to rotate intermittently, each time rotating a fixed angle. And every time the riveting seat 31 rotates once, the center position of one of the riveting grooves 33 is aligned with the riveting head 10. The connection between the riveting head 10 and the output shaft of the hydraulic cylinder 9 is detachable by bolts for conveniently replacing according to different specifications of castings. A square connection block is fixedly arranged at the bottom of the output shaft of the hydraulic cylinder 9. A square sleeve adapted to the square connection block is fixedly arranged at the top of the riveting head 10. The square sleeve is detachably sleeved on the outer wall of the square connection block. And a threaded hole is opened on the outer wall of the square sleeve, and a bolt is threadedly connected inside the threaded hole. By tightening or loosening the bolt, the positioning or disassembly of the riveting head 10 is completed.

[0026] Embodiment 2: The main difference between this embodiment and the first technical solution is as follows: For a riveting and pressing device for casting processing, the component bearing mechanism 3 includes a riveting seat 31, a rotating shaft fixedly connected to the bottom of the riveting seat 31, and a gear ring 32 fixedly sleeved on the outer wall of the riveting seat 31. A plurality of riveting grooves 33 are evenly formed at the top of the riveting seat 31. Clamping plates 34 are slidably connected to both sides of the bottom of each riveting groove 33. A spring 35 is fixedly connected between the clamping plate 34 and the opposite side wall of the riveting groove 33. A positioning post 36 for restricting the position of the cylindrical casting is fixedly arranged at the central position of the bottom of the riveting groove 33. A T-shaped slider is fixedly connected to the bottom of the clamping plate 34. T-shaped chutes adapted to the structure of the T-shaped slider are formed on both sides of the bottom of the riveting groove 33. The T-shaped slider is slidably connected in the T-shaped chute.

[0027] During use, first take a cylindrical casting to be processed, manually push open the two clamping plates 34 inside the riveting groove 33, and use its cavity to sleeve outside the positioning post 36. The outer diameter of the positioning post 36 is adapted to the inner diameter of the cavity of the cylindrical casting. Then release the two clamping plates 34, and the two clamping plates 34 will stably clamp the cylindrical casting without any position offset in the longitudinal direction. Next, place another connecting fitting to be riveted to the cylindrical casting on the top of the cylindrical casting, insert a rivet into the connecting hole shared by the cylindrical casting and the connecting fitting, and ensure that the top end of the rivet is located at the center of the riveting groove 33. Then push down the push button switch 6. The system where the hydraulic cylinder 9 is located and the circuit where the servo motor 4 is located are simultaneously activated. The hydraulic cylinder 9 drives the riveting head 10 to move downward slowly and uniformly. At the same time, the servo motor 4 drives the gear 5 to rotate. Since the gear 5 is meshed with the gear ring 32, the gear ring 32 drives the riveting seat 31 to rotate uniformly. Both the hydraulic cylinder 9 and the servo motor 4 are controlled by the control box. By programming the control unit inside the control box, when a time gap of thirty seconds occurs when one of the riveting grooves 33 at the top of the riveting seat 31 reaches directly below the riveting head 10, the riveting head 10 is still located directly above the riveting groove 33 and is gradually approaching. Within thirty seconds, the riveting head 10 approaches the rivet and squeezes the top of the rivet. One end of the rivet expands to form a riveting head, forming a firm connection between the cylindrical casting and the connecting fitting. At the same time, during the intermittent period of the riveting seat 31, the staff takes out the already riveted parts from the riveting groove 33, and re-places the cylindrical casting to be riveted, the matching connecting fitting and the rivet. After one riveting operation is completed, push down the push button switch 6 again to perform the next riveting operation.
