A finishing device for diamond grinding wheels

Abstract

A finishing device for diamond grinding wheels belongs to the field of grinding wheel processing technology. The cutting mechanism includes a cutting tool, a translation mechanism, and a rotation mechanism. The cutting tool is mounted on the translation mechanism via a gear and rack mechanism, and the translation mechanism is connected to the rotation mechanism. The grinding wheel clamping device includes a support base and a guide rod that moves up and down along the support base. At least three linkage mechanisms are rotatably connected between the guide rod and the support base. Each linkage mechanism has a clamping plate. The bottom end of the support base rests against the upper surface of the semi-finished grinding wheel. When the guide rod is pulled upwards, the linkage mechanism, with the support base as its fulcrum, moves upwards with the guide rod, while the lower end drives the clamping plate to close inwards and clamp the outer circumference of the semi-finished grinding wheel. When the grinding wheel clamping device lifts the semi-finished grinding wheel, the linkage mechanism and the weight of the semi-finished grinding wheel reach equilibrium, allowing it to be translated onto a rotary table. The semi-finished grinding wheel is then lowered, the guide rod descends along the support base, and the linkage mechanism drives the clamping plate to release the semi-finished grinding wheel.

Description

Technical Field

[0001] A finishing device for diamond grinding wheels belongs to the field of grinding wheel processing technology. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are abrasives in which ordinary abrasives are bonded together with a binder to form a certain shape and have a certain strength. They are used for grinding, polishing, cutting, and polishing.

[0003] The production process of grinding wheels mainly includes processes such as batching, mixing, grinding wheel forming, and grinding wheel curing. After the mixed materials are pressed into semi-finished products through a forming mold, they are sintered by hot pressing to form finished products. The material of the semi-finished grinding wheels is relatively soft, and cutting the inner and outer diameters of the semi-finished grinding wheels can more easily form the required grinding wheel size. At present, grinding wheel processing lacks specialized equipment and mainly relies on manual processing of the inner and outer diameters. In addition, because the material of the semi-finished grinding wheels is relatively soft, improper transportation can damage the grinding wheels. In the existing technology, such as the patent CN216105534U, the grinding wheel transportation device has two sets of docking claw hooks on both sides. Each set of docking claw hooks is controlled and locked by a set of control components and two sets of locking components. The locking cylinders of four sets of locking components need to be inserted into the connecting holes on the docking claw hooks at the same time to lock them. This is not only complex in structure, but also prone to damage if one side is not locked and the semi-finished grinding wheel tilts. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a finishing device for diamond grinding wheels, which can process the inner and outer circles of the grinding wheel, and the grinding wheel clamping device can clamp and transfer the grinding wheel to prevent the grinding wheel from being damaged during transportation.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the finishing device for the diamond grinding wheel includes a rotary table, a cutting mechanism and a grinding wheel clamping device. The cutting mechanism is set on one side of the rotary table and the grinding wheel clamping device is set on the upper side of the rotary table. The cutting mechanism includes a cutting tool, a translation mechanism, and a rotation mechanism. The cutting tool is raised and lowered on the translation mechanism via a gear and rack mechanism, and the translation mechanism is connected to the rotation mechanism. The grinding wheel clamping device includes a support base and a guide rod that moves up and down along the support base. At least three linkage mechanisms are rotatably connected between the guide rod and the support base, and each linkage mechanism is provided with an arc-shaped clamping plate.

[0006] Preferably, the linkage mechanism includes a first link and a second link. The first link is rotatably connected to the guide rod. One end of the second link is connected to the first link, and the other end is connected to the clamping plate. The support base is provided with at least three support rods, and the middle part of the second link is rotatably connected to the support rods.

[0007] Preferably, a pressure plate is fixedly connected to the lower side of the support base.

[0008] Preferably, the translation mechanism includes a base, a lead screw, and a first handwheel. The base is connected to the rotation mechanism, and the first handwheel is located at one end of the lead screw, allowing the lead screw to rotate on the base. A gear and rack mechanism is connected to the lead screw, and a guide mechanism is provided between the gear and rack mechanism and the base.

[0009] Preferably, the guiding mechanism includes a translation frame and a guide rail. The guide rail is mounted on the base, and the translation frame is provided with a slider that cooperates with the guide rail. A gear and rack mechanism is mounted on the translation frame.

[0010] Preferably, the gear and rack mechanism includes a gear and a rack, the rack is lifted and mounted on the translation frame, the gear is mounted on the translation frame and meshes with the rack, and the gear is connected to the second handwheel.

[0011] Preferably, the rotating mechanism includes a rotating base, a gear set and a rotating motor. The rotating motor is connected to one gear in the gear set, the base is connected to another gear, and the other gear is rotatably mounted on the rotating base.

[0012] Preferably, the upper end of the guide rod is provided with a lifting ring.

[0013] Preferably, the rotary table includes a receiving tray, a fixed tray, and a turntable, which are arranged sequentially from top to bottom with gradually increasing diameters. Each of the turntable, fixed tray, and receiving tray has a through hole at its center.

[0014] Compared with existing technologies, the beneficial effects of this technical solution are: The clamping plate of this utility model is placed around the outer circle of the semi-finished grinding wheel through a linkage mechanism. The bottom end of the support base rests on the upper end surface of the semi-finished grinding wheel. When the guide rod is pulled upward, the linkage mechanism moves upward with the guide rod using the support base as the fulcrum. The lower end drives the clamping plate to close inward and clamp the outer circle of the semi-finished grinding wheel. When the grinding wheel clamping device lifts the semi-finished grinding wheel, the linkage mechanism and the weight of the semi-finished grinding wheel reach a balanced state, and it can be moved to the rotary table. The semi-finished grinding wheel is lowered, the guide rod descends along the support base, and the linkage mechanism drives the clamping plate to release the semi-finished grinding wheel. The grinding wheel clamping device is removed, and the cutting mechanism processes it to achieve the cutting of the inner or outer diameter of the diamond grinding wheel. Attached Figure Description

Detailed Implementation

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0022] Reference Figure 1 The finishing device for the diamond grinding wheel includes a rotary table 1, a cutting mechanism 2, a rotating mechanism 3, and a grinding wheel clamping device 4. The cutting mechanism 2 is connected to the rotating mechanism 3. The cutting mechanism 2 includes a cutting tool 5 and a translation mechanism 27. The cutting tool 5 is raised and lowered on the translation mechanism 27 through a gear and rack mechanism. The translation mechanism 27 is connected to the rotating mechanism 3. The grinding wheel clamping device 4 transports the semi-finished grinding wheel to the rotary table 1. The rotary table 1 fixes the semi-finished grinding wheel. The rotating mechanism 3 drives the translation mechanism 27 and the cutting tool 5 to rotate to the upper side of the rotary table 1. The translation mechanism 27 and the gear and rack mechanism adjust the horizontal displacement and height of the cutting tool 5.

[0023] The rotary table 1 includes a receiving tray 32, a fixed tray 31, and a turntable 30. The receiving tray 32 has three supporting legs. The turntable 30 and the fixed tray 31 are arranged sequentially on the receiving tray 32 from top to bottom. The receiving tray 32 has the largest diameter and protrudes upward along its circumference to form a material-blocking sidewall. The fixed tray 31 is mounted on the upper side of the receiving tray 32 via its supporting legs. The turntable 30 is rotatably mounted on the upper side of the fixed tray 31. The turntable 30 is driven to rotate by a turntable motor 37 via a transmission rod located inside the support beam 36. The diameter of the fixed tray 31 is larger than the diameter of the turntable 30. The semi-finished grinding wheel is placed on the turntable 30, and the turntable 30 drives the semi-finished grinding wheel to rotate. The turntable 30, the fixed tray 31, and the receiving tray 32 all have through holes at their centers to avoid cutting by the tool 5.

[0024] Reference Figures 2-3 The rotating mechanism 3 includes a rotating seat 16, a driving gear 17, a driven gear 18, and a rotating motor 15. The rotating motor 15 is connected to the driving gear 17 via a transmission rod. The driven gear 18, which meshes with the driving gear 17, is connected to the rotating seat 16 via a bearing on its lower side and is fixedly connected to the translation mechanism 27 on its upper side. The rotating motor 15 drives the driving gear 17 and the driven gear 18 to rotate, and the translation mechanism 27 rotates around the rotating seat 16. The rotating seat 16 is located on one side of the rotating table 1, so the translation mechanism 27 is rotated to the upper side of the rotating table 1.

[0025] The translation mechanism 27 includes a base 6, a lead screw 7, and a first handwheel 8. The base 6 includes a horizontal plate 33 and a vertical plate 34. The vertical plate 34 is fixedly connected to the driven gear 18. The horizontal plate 33 is located at one end of the vertical plate 34. The lead screw 7 is rotatably mounted on the horizontal plate 33 through two fixed bearings 29. The end of the lead screw 7 is connected to the first handwheel 8. A sliding nut 28 is provided on the lead screw 7. The nut 28 is connected to the translation frame 9. Two sliders 14 are provided on the upper and lower sides of the translation frame 9, and two guide rails 10 are provided on the upper and lower sides of the horizontal plate 33. When the first handwheel 8 is rotated, the lead screw 7 rotates, driving the nut 28 to move linearly, thereby causing the translation frame 9 to move linearly along the guide rails 10.

[0026] Reference Figure 4 The gear and rack mechanism is mounted on the translation frame 9, which includes four fixed frames 35 and two baffles. The fixed frames 35 are positioned between the two baffles, with one baffle connected to the nut 28. The gear and rack mechanism is fixed to the fixed frames 35. The rack 12 moves up and down along the groove of the rack fixing block 39, which is mounted on the fixed frame 35. The rack 12 meshes with the gear 11, which is rotatably mounted on the fixed frame 35. The gear 11 is rotatably mounted between the two vertical fixed frames 35 via the gear fixing block 38. The second handwheel 13 passes through the gear fixing block 38 and is connected to the gear 11. The second handwheel 13 drives the gear 11 to rotate, causing the rack 12 to move up and down vertically. The cutter 5 is positioned at the lower end of the rack 12, thereby driving the cutter 5 to achieve the up and down movement.

[0027] Reference Figure 5 The grinding wheel clamping device 4 includes a support base 20 and a guide rod 19 that moves up and down along the support base 20. Three linkage mechanisms are connected between the guide rod 19 and the support base 20. Each linkage mechanism is equipped with a clamping plate 24. A lifting ring 26 is provided on the upper side of the guide rod 19, and a circular pressure plate 25 is provided on the lower side of the support base 20.

[0028] Specifically, the linkage mechanism includes a first link 21 and a second link 22. The support base 20 includes a sleeve and a support rod 23 horizontally mounted on the sleeve. A reinforcing plate is provided between the support rod 23 and the sleeve. The first link 21 is a straight connecting rod, and the second link 22 is a bent connecting rod, divided into a first connecting section and a second connecting section. The included angle between the first connecting section and the second connecting section is less than 180 degrees. The first connecting section of the second link 22 is rotatably connected to the first link 21 and the support rod 23. A clamping plate 24 is provided at the end of the second connecting section of the second link 22. The support rod 23 is close to... One end of the second connecting rod 22 is bent upward and connected to the second connecting rod 22. The bent ends of the first connecting rod 21 and the support rod 23 are provided with an opening groove for the second connecting rod 22 to rotate. When the guide rod 19 is pulled upward, the guide rod 19 drives the first connecting rod 21 upward, which indirectly drives the first connecting section of the second connecting rod 22 to open outward with the support rod 23 as the fulcrum. Then the second connecting section of the second connecting rod 22 drives the clamping plate 24 to retract inward, thereby clamping the outer wheel of the semi-finished grinding wheel. The clamping plate 24 of this utility model is arc-shaped and is set at the end of the second connecting section, which fits against the outer wheel of the semi-finished grinding wheel.

[0029] Work process: The lifting device uses the lifting ring 26 to transport the entire grinding wheel clamping device 4 to the upper side of the semi-finished grinding wheel. The lifting device lowers the guide rod 19 until the pressure plate 25 is in contact with the upper surface of the semi-finished grinding wheel. At this time, the three clamping plates 24 are not under force and are set on the outside of the semi-finished grinding wheel. The lifting device pulls the guide rod 19 upward, which drives one end of the first connecting rod 21 to move upward. The first connecting section of the second connecting rod 22 opens upward and outward. Then, the second connecting section retracts inward with the support rod 23 as the fulcrum, thereby clamping the outer circle of the semi-finished grinding wheel. The semi-finished grinding wheel continues to be lifted upward. The weight of the semi-finished grinding wheel and the pulling force of the pull rod mechanism reach a balance, and the semi-finished grinding wheel is transported to the rotary table 1. After the lifting device places the semi-finished grinding wheel on the turntable 30, the gravity is released, the guide rod 19 descends, the first connecting section of the first connecting rod 21 and the second connecting rod 22 descends and retracts, the second connecting section drives the clamping plate 24 to release the semi-finished grinding wheel, and the guide rod 19 is pulled upward again, the grinding wheel clamping device 4 releases the semi-finished grinding wheel and moves away from the turntable 1. At this time, the rotary motor 15 drives the gear set to rotate, and rotates the translation mechanism 27 and the cutter 5 to the upper side of the rotary table 1. The first handwheel 8 is rotated to make the cutter 5 move along the base 6 to the required position and align with the inner or outer diameter of the semi-finished grinding wheel. The second handwheel 13 is rotated to make the cutter 5 descend along the rack 12 and cut into the semi-finished grinding wheel. At this time, the turntable 30 of the rotary table 1 rotates, and the cutter 5 continues to descend, completing the cutting of the semi-finished grinding wheel.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
