Description

Technical Field

[0001] The utility model relates to a disc diamond roller, belonging to the technical field of diamond rollers. Background Art

[0002] A diamond roller is a high-efficiency, long-life and low-cost grinding wheel dressing tool for special machine tools for mass production grinding and gear grinding machines.

[0003] Chinese published patent (Publication No.: CN 217097279 U) discloses a disc diamond roller, which includes an upper positioning and clamping assembly. A lower positioning and clamping assembly is detachably installed at the bottom of the upper positioning and clamping assembly. A diamond roller disc is detachably installed between the upper positioning and clamping assembly and the lower positioning and clamping assembly. A fixing bolt is embedded and installed inside the upper positioning and clamping assembly. In the above solution, the upper fixing rack is fixedly installed inside the connecting ring, and upper heat dissipation holes are formed on the surface of the metal connecting block. During the operation of the device, through the positioning of the positioning rod, the upper positioning and clamping assembly and the lower positioning and clamping assembly are clamped and installed on the equipment. The diamond roller is embedded and installed on the equipment through the upper anti-slip groove, avoiding phenomena such as slipping when rotating the dressing tool. The star-shaped embedding block is embedded and installed inside the star-shaped connection groove through the star-shaped groove, and tightened by the fixing bolt, making the workpiece processing more ideal, increasing the service life of the diamond roller and reducing the use cost;

[0004] Although the above patent completes disassembly and installation by tightening the fixing bolt, the shaping piece can be replaced, saving resources and reducing the use cost. However, since the diamond roller is installed on the dressing device of the grinding machine and then processed by the grinding machine, the contour shape, size and precision of the diamond roller are designed and manufactured according to the corresponding technical requirements of the parts to be processed. Therefore, the installation size is determined according to the connection size requirements of the dressing device on the user's machine tool. So the inner hole sizes of the diamond rollers are uneven. But when fixing the diamond roller, diamond rollers with different inner hole sizes cannot be fixed.

[0005] Therefore, a disc diamond roller is proposed. Summary of the Utility Model

[0006] In view of this, the utility model provides a disc diamond roller to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0007] The technical solution of the utility model is realized as follows: A disc diamond roller includes a roller sheet, an upper pressing plate and a bottom plate. A limiting mechanism is arranged inside the roller sheet and the upper pressing plate. The limiting mechanism includes a rotating shaft and a push rod. The rotating shaft is rotatably connected to the top of the bottom plate through a bearing. A round plate is rotatably connected to the top of the rotating shaft through a bearing. Spiral grooves are formed on the outer surface of the round plate. The tops of the three push rods are fixedly connected with round blocks. The outer walls of the three round blocks are slidably connected to the inner cavities of the three spiral grooves. Arc-shaped pressing plates are fixedly connected to the outer sides of the three push rods. The outer sides of the three arc-shaped pressing plates are in contact with the inner hole of the roller sheet. An annular clamping groove is formed in the middle of the top of the round plate.

[0008] Further preferably, limiting grooves are formed on the inner surfaces of the annular clamping grooves. An annular clamping block is fixedly connected to the middle of the bottom of the upper pressing plate.

[0009] Further preferably, limiting blocks are fixedly connected to the outer surfaces of the annular clamping blocks. The annular clamping blocks and the limiting blocks are clamped in the inner cavities of the annular clamping grooves and the limiting grooves.

[0010] Further preferably, sliders are fixedly connected to the bottoms of the three push rods. Sliding grooves are formed on the top of the bottom plate and on the outer side of the rotating shaft. The bottoms of the three sliders are slidably connected to the inner cavities of the three sliding grooves.

[0011] Further preferably, a first friction gasket is fixedly connected to the outer wall of the limiting block. A second friction gasket is fixedly connected to the outer walls of the three arc-shaped pressing plates.

[0012] Further preferably, handles are fixedly connected to the four peripheries of the top of the upper pressing plate. Central shafts are fixedly connected to the top of the bottom plate and the top of the upper pressing plate.

[0013] Further preferably, a plurality of anti-slip grooves are formed in the inner walls of the two central shafts. Positioning rods are fixedly connected to the outer walls of the two central shafts.

[0014] Due to the adoption of the above technical solution in the embodiment of the utility model, it has the following advantages:

[0015] First, in the utility model, by aligning the annular clamping block and the limiting block with the annular clamping groove and the limiting groove and pressing the upper pressing plate downward, the annular clamping block and the limiting block are clamped in the inner cavities of the annular clamping groove and the limiting groove. Hold one end of the handle. Since the annular clamping block and the limiting block are clamped with the annular clamping groove and the limiting groove, the upper pressing plate can be driven to rotate counterclockwise. Through the action of the rotating shaft, the round plate can be driven to rotate counterclockwise, so that the round block slides in the inner cavity of the spiral groove, driving the arc-shaped pressing plate to push outward, and making the arc-shaped pressing plate fit with the inner hole of the roller sheet, achieving the function of internally fixing the roller sheet.

[0016] Second, the utility model can be conveniently clamped with the annular slot by setting the annular clamping block, can be conveniently connected with the limiting slot by setting the limiting block, can improve the stability of the push rod during movement by setting the slider and the sliding groove, can improve the friction between the limiting block and the limiting slot by setting the first friction gasket and the second friction gasket, and the second friction gasket can improve the friction between the arc-shaped pressing plate and the inner hole of the roller piece, avoiding the slipping phenomenon. By setting the handle, it is convenient to rotate the upper pressing plate, and by setting the anti-slip groove, it can play an anti-slip role when the roller piece is polished.

[0026] Embodiment 1

[0027] As Figures 1-4 shown, the embodiment of the present utility model provides a disc diamond roller, which includes a roller sheet 1, an upper pressing plate 3 and a bottom plate 4. A limiting mechanism 2 is arranged inside the roller sheet 1 and the upper pressing plate 3. The limiting mechanism 2 includes a rotating shaft 201 and a push rod 205. The rotating shaft 201 is rotatably connected to the top of the bottom plate 4 through a bearing. A circular plate 202 is rotatably connected to the top of the rotating shaft 201 through a bearing. Spiral grooves 203 are formed on the outer surface of the circular plate 202. The tops of three push rods 205 are fixedly connected with circular blocks 204. The outer walls of the three circular blocks 204 are slidably connected to the inner cavities of the three spiral grooves 203. The outer sides of the three push rods 205 are fixedly connected with arc-shaped pressing plates 206. The outer sides of the three arc-shaped pressing plates 206 are in contact with the inner hole of the roller sheet 1. An annular card slot 207 is formed in the middle of the top of the circular plate 202.

[0028] By aligning the annular clamping block 209 and the limiting block 210 with the annular card slot 207 and the limiting slot 208 and pressing down the upper pressing plate 3, the annular clamping block 209 and the limiting block 210 are clamped in the inner cavities of the annular card slot 207 and the limiting slot 208. Hold one end of the handle 7. Since the annular clamping block 209 and the limiting block 210 are clamped with the annular card slot 207 and the limiting slot 208, the upper pressing plate 3 can be driven to rotate counterclockwise. Through the action of the rotating shaft 201, the circular plate 202 can be driven to rotate counterclockwise, so that the circular block 204 slides in the inner cavity of the spiral groove 203, driving the arc-shaped pressing plate 206 to push outward, and making the arc-shaped pressing plate 206 fit with the inner hole of the roller sheet 1, so as to achieve the effect of internally fixing the roller sheet 1.

[0029] Embodiment 2

[0030] In one embodiment, limiting grooves 208 are formed in the inner surfaces of the annular clamping grooves 207. The middle end of the bottom of the upper pressing plate 3 is fixedly connected with an annular clamping block 209. Limiting blocks 210 are fixedly connected to the outer surfaces of the annular clamping block 209. The annular clamping block 209 and the limiting blocks 210 are clamped in the inner cavities of the annular clamping grooves 207 and the limiting grooves 208. The bottoms of the three push rods 205 are fixedly connected with sliders 211. Sliding grooves 212 are formed in the top of the bottom plate 4 and on the outer side of the rotating shaft 201. The bottoms of the three sliders 211 are slidably connected to the inner cavities of the three sliding grooves 212. A first friction gasket 5 is fixedly connected to the outer wall of the limiting block 210. A second friction gasket 6 is fixedly connected to the outer walls of the three arc-shaped pressing plates 206. Handles 7 are fixedly connected to the peripheries of the top of the upper pressing plate 3. Central shafts 8 are fixedly connected to the top of the bottom plate 4 and the top of the upper pressing plate 3. A plurality of anti-slip grooves 9 are formed in the inner walls of the two central shafts 8. Positioning rods 10 are fixedly connected to the outer walls of the two central shafts 8.

[0031] By providing the annular clamping block 209, it can be conveniently clamped with the annular clamping groove 207. By providing the limiting blocks 210, it can be conveniently connected with the limiting grooves 208. By providing the sliders 211 and the sliding grooves 212, the stability of the push rod 205 during movement can be improved. By providing the first friction gasket 5 and the second friction gasket 6, the friction between the limiting block 210 and the limiting groove 208 can be increased. The second friction gasket 6 can increase the friction between the arc-shaped pressing plate 206 and the inner hole of the roller piece 1, avoiding slipping. By providing the handles 7, it is convenient to rotate the upper pressing plate 3. By providing the anti-slip grooves 9, it can play an anti-slip role when the roller piece 1 is polished.

[0032] When the utility model is working: First, place the roller piece 1 on the top of the bottom plate 4. Align the annular clamping block 209 and the limiting block 210 with the annular clamping groove 207 and the limiting groove 208, and then press down the upper pressing plate 3, so that the annular clamping block 209 and the limiting block 210 are clamped in the inner cavities of the annular clamping groove 207 and the limiting groove 208. Hold one end of the handle 7. Since the annular clamping block 209 and the limiting block 210 are clamped with the annular clamping groove 207 and the limiting groove 208, the upper pressing plate 3 can be driven to rotate counterclockwise. Through the action of the rotating shaft 201, the circular plate 202 can be driven to rotate counterclockwise, so that the circular block 204 slides in the inner cavity of the spiral groove 203, driving the arc-shaped pressing plate 206 to push outward, so that the arc-shaped pressing plate 206 fits with the inner hole of the roller piece 1, achieving the effect of internally fixing the roller piece 1. When it is necessary to disassemble the roller piece 1, hold one end of the handle 7, which can drive the upper pressing plate 3 to rotate clockwise. Through the action of the rotating shaft 201, the circular plate 202 can be driven to rotate clockwise, so that the circular block 204 slides in the inner cavity of the spiral groove 203, driving the arc-shaped pressing plate 206 to move inward, so that the arc-shaped pressing plate 206 is disengaged from the inner hole of the roller piece 1. Lift the upper pressing plate 3 upward, so that the annular clamping block 209 and the limiting block 210 are disengaged from the inner cavities of the annular clamping groove 207 and the limiting groove 208, completing the disassembly of the roller piece 1, and the roller piece 1 can be replaced.

[0033] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
