[0022] Example 1
[0023] Please see Figure 1-6 A polishing device for stainless steel kitchenware production includes a support frame 1, a working plate 2, an inner grinding assembly 3, and an outer grinding assembly 4. The working plate 2 is fixedly connected to the inner wall of the support frame 1. Both the inner grinding assembly 3 and the outer grinding assembly 4 are connected to the support frame 1. The inner grinding assembly 3 and the outer grinding assembly 4 are used to polish the inner and outer walls of the workpiece, respectively. When polishing the inner wall of the workpiece, the outer grinding assembly 4 clamps the workpiece, and the inner grinding assembly 3 extends into the workpiece, contacts the inner wall of the workpiece, and rotates to polish the workpiece. When polishing the outer wall of the workpiece, the outer grinding assembly 4 contacts the outer surface of the workpiece, and the inner grinding assembly 3 supports and fixes the workpiece internally and drives the workpiece to rotate.
[0024] The internal grinding assembly 3 includes an internal grinding motor 301, a connecting column 302, a connecting plate 303, a fixing plate 304, an outer sleeve 305, an inner sleeve 306, a crank handle 307, an internal grinding screw 308, and an internal grinding screw block 309. The internal grinding motor 301 is fixedly connected to the top surface of the support frame 1. The output shaft of the internal grinding motor 301 passes through the support frame 1 and is fixedly connected to the connecting column 302. The bottom surface of the connecting column 302 is fixedly connected to the connecting plate 303. The bottom surface of the connecting plate 303 is fixedly connected to... There is an inner sleeve 306, and an outer sleeve 305 is slidably connected to the outer wall of the inner sleeve 306. A fixing plate 304 is fixedly connected to the bottom surface of the outer sleeve 305. An inner grinding screw 308 is rotatably connected to the fixing plate 304. The lower end of the inner grinding screw 308 passes through the fixing plate 304 and is fixedly connected to a rocker handle 307. The inner grinding screw 308 is located inside the outer sleeve 305. An inner grinding screw block 309 is fixedly connected inside the inner sleeve. The inner grinding screw block 309 is threadedly connected to the inner grinding screw 308.
[0025] The internal grinding assembly 3 also includes an internal grinding guide groove 310, a guide rod 311, a first connecting vertical plate 312, a second connecting vertical plate 313, a connecting rod 314, an inverted L-shaped plate 315, and an arc-shaped grinding block 316. The connecting plate 303 has several sets of internal grinding guide grooves 310 arranged in a circumferential array. The guide rods 311 are slidably connected in the internal grinding guide grooves 310. The outer wall of the outer sleeve 305 is fixedly connected to several sets of first connecting vertical plates 312 arranged in a circumferential array. The connecting rods 314 are rotatably connected to the first connecting vertical plates 312. The other end of the connecting rods 314 is rotatably connected to the second connecting vertical plate 313. The inverted L-shaped plate 315 is fixedly connected to the outer side of the second connecting vertical plate 313. The arc-shaped grinding block 316 is fixedly connected to the outer side of the inverted L-shaped plate 315.
[0026] When the position of the arc-shaped grinding block 316 needs to be adjusted according to the inner wall size of the workpiece, the crank handle 307 is turned, which drives the inner grinding screw 308 to rotate. Since the inner grinding screw block 309 is fixed inside the inner sleeve 306 and threadedly connected to the inner grinding screw 308, the outer sleeve 305 will move up and down along the inner sleeve 306. When the outer sleeve 305 moves, it drives the inverted L-shaped plate to move through the first connecting vertical plate 312, the connecting rod 314 and the second connecting vertical plate 313, thereby realizing the radial scaling of the arc-shaped grinding block 316. After the inner grinding motor 301 is started, its power is transmitted to the connecting plate 303 and the inner sleeve 306 through the connecting column 302, which in turn drives the inner sleeve 306 to rotate, providing power for the rotation of the arc-shaped grinding block 316, enabling it to grind the inner wall of the workpiece.
[0027] Example 2
[0028] This embodiment adds the following improvements to Embodiment 1: The external grinding assembly 4 includes an external grinding motor 401, a first transmission bevel gear 402, a second transmission bevel gear 403, a bidirectional threaded rod 404, a guide crossbar 405, a guide block 406, and an external grinding block 407. The external grinding motor 401 is fixedly connected to the bottom surface inside the support frame 1, and the bidirectional threaded rod 404 and the guide crossbar 405 are rotatably connected to it. The output shaft of the external grinding motor 401 is fixedly connected to the first transmission bevel gear 402, and the middle section of the bidirectional threaded rod 404 is fixedly connected to the second transmission bevel gear 403. The first transmission bevel gear 402 and the second transmission bevel gear 403 mesh with each other. The left and right sides of the bidirectional threaded rod 404 are threadedly connected to the external grinding block 407, and the left and right sides of the guide crossbar 405 are slidably connected to the guide block 406.
[0029] The external grinding assembly 4 also includes a connecting vertical rod 408, an arc plate 409, an external grinding guide groove 410, and a grinding layer 411. The working plate 2 has two sets of parallel external grinding guide grooves 410. The upper part of the external grinding block 407 and the guide block 406 are both fixedly connected to the connecting vertical rod 408. The connecting vertical rod 408 is slidably connected to the external grinding guide groove 410. The upper end of the connecting vertical rod 408 located on the same side passes through the external grinding guide groove 410 and is fixedly connected to the arc plate 409. The inner side of the arc plate 409 is fixedly connected to the grinding layer 411.
[0030] The output shaft of the external grinding motor 401 drives the first transmission bevel gear 402 to rotate, which in turn drives the bidirectional threaded rod 404 to rotate through meshing with the second transmission bevel gear 403. External grinding blocks 407 are threadedly connected to the left and right sides of the bidirectional threaded rod 404, and the synchronous movement of the external grinding blocks 407 is achieved through threaded transmission, thereby adjusting the contact pressure between the external grinding blocks 407 and the outer surface of the workpiece. The guide block 406 slides on the guide crossbar 405 to ensure stable movement of the external grinding blocks 407. The external grinding blocks 407 are connected to the arc-shaped plate 409 via a connecting vertical rod 408. A polishing layer 411 is fixed to the inner side of the arc-shaped plate 409 to achieve uniform polishing of the outer surface of the workpiece.
[0031] Working principle
[0032] When the position of the arc-shaped grinding block 316 needs to be adjusted according to the inner wall size of the workpiece, the crank handle 307 is turned, which drives the inner grinding screw 308 to rotate. Since the inner grinding screw block 309 is fixed inside the inner sleeve 306 and threadedly connected to the inner grinding screw 308, the outer sleeve 305 will move up and down along the inner sleeve 306. When the outer sleeve 305 moves, it drives the inverted L-shaped plate to move through the first connecting vertical plate 312, the connecting rod 314 and the second connecting vertical plate 313, thereby realizing the radial scaling of the arc-shaped grinding block 316. After the inner grinding motor 301 is started, its power is transmitted to the connecting plate 303 and the inner sleeve 306 through the connecting column 302, which in turn drives the inner sleeve 306 to rotate, providing power for the rotation of the arc-shaped grinding block 316, enabling it to grind the inner wall of the workpiece.
[0033] The output shaft of the external grinding motor 401 drives the first transmission bevel gear 402 to rotate, which in turn drives the bidirectional threaded rod 404 to rotate through meshing with the second transmission bevel gear 403. External grinding blocks 407 are threadedly connected to the left and right sides of the bidirectional threaded rod 404, and the synchronous movement of the external grinding blocks 407 is achieved through threaded transmission, thereby adjusting the contact pressure between the external grinding blocks 407 and the outer surface of the workpiece. The guide block 406 slides on the guide crossbar 405 to ensure stable movement of the external grinding blocks 407. The external grinding blocks 407 are connected to the arc-shaped plate 409 via a connecting vertical rod 408. A polishing layer 411 is fixed to the inner side of the arc-shaped plate 409 to achieve uniform polishing of the outer surface of the workpiece.
[0034] The internal grinding assembly 3 and the external grinding assembly 4 work together. When polishing the inner wall of the workpiece, the outer grinding block 407 of the external grinding assembly 4 clamps and fixes the workpiece, while the arc-shaped grinding block 316 of the internal grinding assembly 3 extends into the workpiece and is driven to rotate by the internal grinding motor 301, thus polishing the inner wall of the workpiece. When polishing the outer wall of the workpiece, the outer grinding block 407 of the external grinding assembly 4 contacts the outer surface of the workpiece and is driven to rotate by the external grinding motor 401. At the same time, the arc-shaped grinding block 316 of the internal grinding assembly 3 supports and fixes the workpiece and drives it to rotate, thus polishing the outer wall of the workpiece. The coordinated work of the internal grinding assembly 3 and the external grinding assembly 4 ensures efficient and uniform polishing of the inner and outer walls of the workpiece, improving product quality and production efficiency.
