[0002] A hardware grinding and polishing device is a device specially used for surface grinding and polishing of hardware. Its purpose is to remove defects and rough parts on the surface of hardware through mechanical action, so that the surface becomes smooth, flat and shiny, thereby improving the appearance quality and performance of the hardware. For example, the Chinese patent announcement number CN217167833U discloses a tubular hardware grinding device, including a base, a mounting block and a cross frame. Two groups of sliding openings are symmetrically opened on the left side of the upper surface of the base, and connecting blocks are installed inside the sliding openings for limiting sliding. The upper ends of the connecting blocks are fixed with splints, and a base is fixed on the upper surface of the base between the two groups of sliding openings. The grinding device is inserted into the interior of the hardware, and the motor is working at the same time. The output end thereof can drive the rotating shaft to rotate through the meshing transmission of the gear set, thereby driving the grinding disc to rotate. With the stable advancement of the driving component, the grinding disc can fully rub the burrs and flash on the inner wall surface of the hardware, thereby polishing the inside of the hardware cleanly, replacing traditional manual polishing, providing a stable polishing effect, avoiding uneven polishing, and thereby improving the polishing efficiency of tubular hardware.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention arranges two grinding rollers to be inserted into the through hole, so that when the clamping force of the first clamping block and the second clamping block is relatively small, the rotation of the hardware to be processed can be ensured, deformation or damage of the hardware to be processed caused by excessive clamping force can be avoided, and the reliability of the grinding and polishing process can be improved.

[0016] The present invention provides a spring between the grinding roller and the fixed block, so that during the rotation of the hardware to be processed, the grinding roller can move outward under the action of centrifugal force, thereby preventing waste chips from entering the hardware to be processed through the through hole, reducing the subsequent cleaning steps, and at the same time increasing the contact area between the grinding roller and the through hole, thereby improving the rotation stability of the hardware to be processed.

A first motor 25 is provided on one side of the second clamping block 22, and the output end of the first motor 25 is fixedly connected to the second clamping block 22.

[0023] Furthermore, the fixing mechanism 4 includes an installation box 41, in which a bidirectional screw rod 44 is rotatably connected, a second motor 42 is fixedly installed at one end of the installation box 41, an output end of the second motor 42 is fixedly connected to one end of the bidirectional screw rod 44, screw sleeves 43 are threadedly sleeved on both ends of the rod body of the bidirectional screw rod 44, and the screw sleeves 43 are slidably connected to the installation box 41, the base plate 1 is fixedly installed in the middle of the upper surface of the installation box 41, the reduction cylinder 31 is fixedly installed in the middle of the upper surface of the base plate 1, telescopic rods 32 are arranged on both sides of the reduction cylinder 31, and the bottoms of the telescopic rods 32 on both sides are fixedly installed at both ends of the upper surface of the base plate 1, the grinding plate 33 abuts against the outer peripheral surface of the hardware 5 to be processed, and both ends of the grinding plate 33 and the polishing plate 34 are fixed with fasteners.

[0024] In the present application, the bidirectional screw 44 is driven to rotate by the second motor 42, and the two screw sleeves 43 are moved closer or farther away from each other at the same time through the threaded cooperation between the bidirectional screw 44 and the screw sleeve 43 and the sliding cooperation between the screw sleeve 43 and the inner wall of the installation box 41, so that the hardware 5 to be processed can be quickly fixed and loosened.

[0025] Furthermore, the first clamping block 21 and the second clamping block 22 are rotatably installed in the first mounting frame 23 and the second mounting frame 24 respectively, the first mounting frame 23 and the second mounting frame 24 are fixedly installed on the upper surfaces of the two screw sleeves 43 respectively, the first motor 25 is fixedly installed on one side of the second mounting frame 24, the screw 26 threadedly passes through the first clamping block 21, the first support plate 27 is fixedly connected to one side of the first clamping block 21, and the fixed block 28 is fixedly connected to one end of the first support plate 27 away from the first clamping block 21.

[0026] Specifically, the second pressing block 22 of the first pressing block 21 is conical and is respectively inserted at both ends of the hardware 5 to be processed. When working, the first pressing block 21 and the second pressing block 22 are driven by the two screw sleeves 43 to approach each other, and the hardware 5 to be processed is pressed tightly. The second pressing block 22 is driven to rotate by the first motor 25, thereby driving the hardware 5 to be processed and the first pressing block 21 to rotate. The first mounting frame 23 and the second mounting frame 24 are respectively sleeved on the first pressing block 21 and the second pressing block 22, and the first pressing block 21 and the second pressing block 22 are pressed tightly. 2 is limited to ensure stability during the grinding process. The screw 26 is used to drive the rack 211 and the movable part 212 to move, so as to realize the rotation of the grinding roller 217 and the movement perpendicular to the hardware 5 to be processed. The two ends of the fixed block 28 are respectively connected to the first support plate 27 and the second support plate 29. The second support plate 29 is inserted into the second abutting block 22. The first support plate 27 is fixedly connected to the first abutting block 21. The first support plate 27 and the second support plate 29 can support the fixed block 28, thereby improving the stability of the components around the fixed block 28.

[0027] When in use, the hardware 5 to be processed is placed on the second support plate 29 and the first support plate 27, with one end abutting against the first clamping block 21. As the first clamping block 21 and the second clamping block 22 move, the other end of the hardware 5 to be processed abuts against the second clamping block 22 to fix the hardware 5 to be processed. At the same time, the second support plate 29 is inserted into the second clamping block 22 to fix the middle structure of the mounting mechanism 2.

[0028] Furthermore, the transmission assembly is composed of a gear 210 and a rack 211, the gear 210 is meshingly connected with the rack 211, the screw 26 is rotatably installed on one end of the rack 211, the end of the rack 211 away from the screw 26 is fixedly connected to the movable part 212, a guide block 213 is fixedly connected to the upper surface of one end of the movable part 212, a guide groove 291 is opened at the bottom of the second support plate 29, and the guide block 213 is slidably connected in the guide groove 291.

[0029] Specifically, through the threaded cooperation between the screw 26 and the first clamping block 21, the screw 26 rotates to drive the rack 211 to move accordingly, and through the threaded cooperation between the rack 211 and the gear 210, the gear 210 drives the grinding roller 217 to rotate. At the same time, the rack 211 drives the movable part 212 to move, and through the abutment cooperation between the movable part 212 and the grinding roller 217, the grinding roller 217 moves outward or retracts inward accordingly.

[0030] By providing a guide block 213 at one end of the movable part 212 to slide in cooperation with the guide groove 291, the movable part 212 and one end of the rack 211 can be guided and supported, thereby improving the strength of the rack 211 and the movable part 212 and the stability during movement. When the grinding roller 217 moves outward, it rotates driven by the gear 210, which can not only push out the waste chips remaining in the through hole 51, but also clean up the burrs generated by grinding at one end of the through hole 51, thereby eliminating the subsequent cleaning steps, enhancing the grinding and polishing effects, and improving production efficiency and product processing quality.

[0031] Furthermore, a mounting sleeve 214 is rotatably connected to the fixed block 28, the gear 210 is fixedly sleeved on the mounting sleeve 214, movable sleeves 215 are slidably sleeved on both sides of the interior of the mounting sleeve 214, the two movable sleeves 215 are respectively fixedly connected to the two grinding rollers 217, and springs 216 are sleeved on the two movable sleeves 215, one end of the spring 216 is fixedly connected to the fixed block 28, and the other end is fixedly connected to a rotating ring 219, the rotating ring 219 is rotatably connected to the grinding roller 217, the movable part 212 is provided with a first connecting part 2121, a second connecting part 2122 and a third connecting part 2123, a retaining ring 218 is integrally provided at one end of the grinding roller 217, and the first connecting part 2121, the second connecting part 2122 and the third connecting part 2123 are sequentially abutted against the retaining ring 218.

[0032] Specifically, the mounting sleeve 214 is sleeved on the gear 210, and the mounting sleeve 214 is rotatably connected to the fixed block 28. Two movable sleeves 215 are slidably connected in the mounting sleeve 214. Two springs 216 are sleeved outside the mounting sleeve 214 and the movable sleeve 215. One end of the spring 216 is rotatably abutted against the grinding roller 217 through the rotating ring 219. In the initial state, the distance between the two end portions of the two grinding rollers 217 is smaller than the diameter of the hardware 5 to be processed. The hardware 5 to be processed can be directly sleeved outside the grinding roller 217, and the retaining ring 218 does not contact the movable part 212. After the hardware 5 to be processed is fixed, the movable part 212 is driven by rotating the screw 26. The movable member 212 moves toward the direction approaching the first support plate 27, so that the retaining ring 218 moves along the inclined surface of one end of the movable member 212 to the first connecting portion 2121, so that the grinding roller 217 extends to a part of the through hole 51, and the grinding roller 217 rotates synchronously with the first clamping block 21 and the second clamping block 22, thereby driving the hardware 5 to be processed to rotate synchronously, which can ensure that the hardware 5 to be processed follows the rotation of the first clamping block 21 and the second clamping block 22, and avoids the situation in which the first clamping block 21 and the second clamping block 22 are over-tightened to ensure the synchronous rotation of the hardware 5 to be processed, resulting in deformation or damage to the end of the hardware 5 to be processed.

[0033] During the rotation and grinding process of the hardware 5 to be processed, the grinding rollers 217 on both sides move outward under the action of centrifugal force, driving the movable sleeve 215 to move synchronously, so that the movable sleeve 215 slides outward in the installation sleeve 214, and at the same time the spring 216 is extended, which can not only increase the contact area between the grinding roller 217 and the through hole 51, but also prevent the debris generated during the grinding process from accumulating in the through hole 51. By providing an outwardly expanding retaining ring 218 at one end of the grinding roller 217, the grinding roller 217 can be prevented from excessively moving outward and causing wear, thereby ensuring the normal operation of the hardware 5 to be processed.

[0034] After the grinding and polishing operations are completed, the hardware 5 to be processed stops rotating, and the grinding roller 217 is retracted under the elastic force of the spring 216 and rests against the first connecting part 2121 again. Then, the movable part 212 is driven to move by rotating the screw 26, so that the retaining ring 218 contacts the second connecting part 2122, so that the grinding roller 217 extends outward. At the same time, the gear 210 drives the mounting sleeve 214, the movable sleeve 215 and the grinding roller 217 to rotate, which can not only grind off the burrs on the inner wall of the through hole 51, but also push out the waste chips remaining in the through hole 51. Then, the retaining ring 218 contacts the third connecting part 2123 and moves inward under the action of the spring 216, so that the grinding roller 217 is disengaged from the through hole 51 inward, which is convenient for subsequent material removal.

[0035] like Figure 1-Figure 10 As shown, a method for using a hardware surface grinding and polishing device provided by an embodiment of the present invention comprises the following steps: One end of the hardware 5 to be processed is sleeved on the first support plate 27 and the second support plate 29, so that one end thereof abuts against the first abutting block 21, and the positions of the two grinding rollers 217 correspond to the through hole 51, and the second motor 42 is started to drive the bidirectional screw rod 44 to rotate, and the two screw rod sleeves 43 are driven to approach each other through the bidirectional screw rod 44, so that the first abutting block 21 and the second abutting block 22 are approached, until the hardware 5 to be processed is abutted by the first abutting block 21 and the second abutting block 22, and the guide block 213 is inserted into the second abutting block 22; The screw rod 26 is rotated to move one end outward, driving the rack 211 to move in a direction away from the second abutting block 22, and the rack 211 drives the movable member 212 to move synchronously, and the first connecting portion 2121 pushes the grinding roller 217 outward, so that the grinding roller 217 is inserted into a part of the through hole 51, ensuring that the hardware 5 to be processed rotates synchronously with the grinding roller 217; Adjust the fasteners so that the polishing plates 34 on both sides are opened outwards and do not contact the hardware 5 to be processed, and fix them after adjustment; The deceleration cylinder 31 is started to drive the grinding plate 33 to move upward and abut against the hardware 5 to be processed, and the first motor 25 is started to drive the hardware 5 to be processed to rotate, and the hardware 5 to be processed is polished by the grinding plate 33. During the polishing process, the grinding rollers 217 on both sides are acted on by the centrifugal force and move outward and further extend into the through hole 51, so as to prevent the grinding debris from entering the inside of the hardware 5 to be processed through the through hole 51, and at the same time ensure the rotation of the hardware 5 to be processed; After the polishing is completed, the polishing plate 34 is adjusted to flip inward so that it abuts against the outer peripheral surface of the hardware 5 to be processed, and the hardware 5 to be processed is driven to rotate by the first motor 25 to achieve polishing of the hardware 5 to be processed; After polishing is completed, the grinding plate 33 and the polishing plate 34 are driven downward by the reduction cylinder 31, and the grinding roller 217 is reset. The rotating screw 26 drives the rack 211 and the movable part 212 to move in the direction close to the first clamping block 21, and the rack 211 drives the gear 210 to rotate, so that the grinding roller 217 rotates, and the retaining ring 218 first contacts with the second connecting part 2122, and moves outward under the push of the second connecting part 2122 to grind the inner wall of the through hole 51, remove the burrs generated by grinding at the end of the through hole 51, and gradually push the waste chips outward, and then the retaining ring 218 contacts with the third connecting part 2123, and under the action of the spring 216, the grinding roller 217 and the retaining ring 218 are retracted into the hardware 5 to be processed for easy removal.

[0036] In summary, the hardware surface grinding and polishing equipment, by setting two grinding rollers 217 to be inserted into the through hole 51, can ensure the rotation of the hardware 5 to be processed when the clamping force of the first clamping block 21 and the second clamping block 22 is relatively small, avoid deformation or damage of the hardware 5 to be processed due to excessive clamping force, and improve the reliability of the grinding and polishing process. By setting a spring 216 between the grinding roller 217 and the fixed block 28, the grinding roller 217 can move outward under the action of centrifugal force during the rotation of the hardware 5 to be processed, so as to avoid waste chips from entering the hardware 5 through the through hole 51. When processing the hardware 5, the subsequent cleaning steps are reduced, and at the same time, the contact area between the grinding roller 217 and the through hole 51 is increased, thereby improving the rotation stability of the hardware 5 to be processed. The screw 26 is arranged to drive the rack 211 and the movable part 212 to move and adjust. The rack 211 is engaged with the gear 210 to drive the grinding roller 217 to rotate, and the movable part 212 pushes the grinding roller 217 to move outward, so that the burrs generated on the inner wall of the through hole 51 can be cleaned and the waste chips remaining in the through hole 51 can be pushed out, thereby enhancing the grinding and polishing effects, and improving the production efficiency and product processing quality.
