Description

Technical Field

[0001] This utility model relates to the technical field of metal product grinding devices, specifically a grinding device for manufacturing metal products. Background Technology

[0002] Metal product grinding equipment is a mechanical device used to process the surface of metal products. It removes defects, burrs, oxide layers or adjusts surface roughness through friction, cutting or polishing to improve the appearance quality, dimensional accuracy or functionality of the product.

[0003] Currently, most existing grinding devices can only perform a single rotary grinding motion, making it difficult to perform comprehensive and uniform grinding of the inner wall of the metal casing. This easily leaves grinding dead corners on the inner wall of the metal casing, resulting in the smoothness and precision of the inner wall failing to meet high standards. Moreover, a single grinding method may not be able to effectively remove some stubborn impurities and protrusions, affecting the quality and performance of metal products. In view of this, we propose a grinding device for metal product manufacturing. Utility Model Content

[0015] This utility model provides a grinding device for manufacturing metal products. It has the following beneficial effects:

[0016] (1) The grinding device for manufacturing metal products has a motor that drives the worm gear to rotate. On the one hand, the short rod and the moving rod are connected by a sliding connection, which causes the moving rod to drive the grinding disc to rotate and grind the inner wall of the metal sleeve. On the other hand, the worm gear drives the worm wheel to rotate, which in turn drives the rotating disk, T-shaped rod and hinge rod to move. Finally, the moving rod drives the grinding disc to make up-down reciprocating motion while rotating. This compound motion mode can grind the inner wall of the metal sleeve more comprehensively and evenly, reduce grinding dead angles, improve grinding quality, and ensure that the smoothness and precision of the inner wall of the metal sleeve meet the production requirements.

[0017] (2) The grinding device for manufacturing metal products can meet the grinding needs of the inner wall of metal sleeves of different sizes by setting replaceable grinding components. When it is necessary to grind metal sleeves of different sizes, the operator only needs to turn the threaded rod and pull it out from the moving rod to easily replace the new grinding components. Then, the threaded rod is connected to the threaded groove on the moving rod to complete the installation. This replaceable design greatly improves the versatility and applicability of the device, avoids the trouble of replacing the entire grinding equipment due to different metal sleeve sizes, effectively reduces production costs and improves production efficiency.

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.

[0029] Please see Figures 1-6 This utility model proposes a grinding device for manufacturing metal products, including a frame 1, an operating table 2 at the upper end of the frame 1, a clamping mechanism on the operating table 2, the clamping mechanism including a hydraulic cylinder 3, a clamping block 4 fixedly connected to the output end of the hydraulic cylinder 3, and a grinding mechanism inside the frame 1.

[0030] In this embodiment of the utility model, in order to polish the inner wall of the metal sleeve, the polishing mechanism specifically includes a motor 51, a worm gear 52 fixedly connected to the output end of the motor 51, a short rod 521 fixedly connected to the end of the worm gear 52, a moving rod 54 having a slot 541, the slot 541 being slidably connected to the short rod 521, the moving rod 54 passing through the operating table 2 and sleeved with the operating table 2, a square groove 544 being opened at the upper end of the moving rod 54, a threaded groove 545 being opened on the inner wall of the square groove 544, a clamping rod 55 being penetrated by a polishing disc 551 and slidably connected with the polishing disc 551, the polishing disc 551 being... The spring is elastically connected to the inner wall of the clamping rod 55. The clamping rod 55 is penetrated by the threaded rod 552 and sleeved with the threaded rod 552. It should be noted that the grinding assembly composed of the clamping rod 55 and the grinding disc 551 can be set in multiple sets for grinding the inner wall of metal sleeves of different sizes. When it is necessary to change the grinding assembly of different sizes, simply turn the threaded rod 552 and pull the threaded rod 552 out of the moving rod 54. Then insert the new moving rod 54 into the square groove 544, then pass the threaded rod 552 through the moving rod 54, and finally thread the threaded rod 552 into the threaded groove 545.

[0031] Furthermore, the worm gear 52 is fitted with a worm wheel 53, which is penetrated by a shaft 531 and fixedly connected to the shaft 531. The shaft 531 penetrates the support plate 11 and is rotatably connected to the support plate 11. A rotating disk 532 is fixedly connected to the end of the shaft 531. A protrusion 533 is fixedly connected to the outer wall of the rotating disk 532. The support plate 11 is penetrated by a T-shaped rod 534 and is slidably connected to the T-shaped rod 534. A sliding groove 535 is provided at the lower end of the T-shaped rod 534. The sliding groove 535 is slidably connected to the protrusion 533. A hinge rod 12 is hinged to the upper end of the T-shaped rod 534. The hinge rod 12 is hinged to the inner wall of the frame 1. A sliding groove 121 is provided at the end of the hinge rod 12. The moving rod 54 penetrates the bearing 542 and is fixedly connected to the inner wall of the bearing 542. A rod body 543 is fixedly connected to the outer wall of the bearing 542. The rod body 543 is slidably connected to the sliding groove 121.

[0032] In this utility model, during use, the metal sleeve is first placed above the grinding disc 551, and then the metal disc is pressed down. At this time, the grinding disc 551 will move inward under the pressure. When the metal sleeve is installed, the grinding disc 551 will press against the inner wall of the metal sleeve under the elastic force of the spring. Then, the hydraulic cylinder 3 is started to clamp the outer wall of the metal sleeve with the clamping block 4. Then, the motor 51 is started. At this time, the worm 52, which is fixedly connected to the output end of the motor 51, rotates. Since the upper end of the worm 52 is fixedly connected to the short rod 521 and the short rod 521 and the moving rod 54 are slidably connected with the groove 541, when the worm 52 rotates, the moving rod 54 drives the clamping rod 55 to rotate synchronously, so that the grinding disc 551 grinds the inner wall of the metal sleeve.

[0033] Meanwhile, as the worm gear 52 rotates, the worm wheel 53, which cooperates with the worm gear 52, will rotate synchronously under the drive of the worm gear 52. At this time, the shaft 531, which is fixedly connected to the worm wheel 53, will drive the rotating disk 532 to rotate. During this process, the protrusion 533, which is fixedly connected to the outer wall of the rotating disk 532, will apply a force to the slide groove 535, causing the T-shaped rod 534 to move up and down reciprocally. At this time, the T-shaped rod 534 will apply a force to the hinge rod 12, causing the hinge rod 12 to move back and forth. At this time, the hinge rod 12 will apply a force to the moving rod 54, causing the moving rod 54 to drive the grinding disc 551 to rotate while moving up and down reciprocating, thereby improving the grinding effect on the inner wall of the metal sleeve.
