Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, and in particular to a diamond grinding device. Background Art

[0002] When processing diamonds, it is usually necessary to make the diamonds into a polyhedron shape, and multiple faces of the diamonds need to be ground by a grinding device. The existing grinding device needs to fix the diamond when in use. After completing the single-side grinding of the diamond, it is necessary to switch the ground side and the unground position. When changing the side, it needs to be manually disassembled and then fixed. This method of use is cumbersome to operate, resulting in reduced grinding efficiency.

[0003] A Chinese patent with announcement number CN220806791U discloses a diamond processing grinding tool, including two clamps, the two clamps are arranged at an interval, and clamps are fixed on both adjacent sides of the two clamps. One side of the two clamps is provided with a threaded hole, and a bidirectional screw is threadedly connected between the two threaded holes. A movable frame is provided at one end of the two clamps.

[0004] When the above technical solution is actually used, the staff starts the servo motor, and the servo motor drives the bidirectional screw to rotate clockwise. The rotation of the bidirectional screw brings the two clamps closer to each other, so that the clamp clamps the diamond. When the diamond needs to be flipped over to change the grinding surface, the first drive motor is started, and the first drive motor drives the mounting rod to rotate, thereby rotating the movable frame. The rotation of the movable frame drives the clamp to rotate, and the clamp drives the diamond to flip, so that there is no need to manually flip the diamond grinding surface.

[0005] Although the above technical solution can make the diamond flip when the clamp is closed, it can only make the diamond rotate along the axis of the mounting rod, and the flipping direction is single. Therefore, only the surface parallel to the axis of the mounting rod can be ground. When the diamond is a conical structure, for example, the diamond is a regular octahedron, the above technical solution still needs to manually adjust the position of the diamond when grinding the diamond, and the grinding efficiency cannot be effectively improved.

[0006] Therefore, the art needs a diamond grinding device to solve the above problems. Summary of the invention

[0007] The present invention provides a diamond grinding device, aiming to solve the problem that the diamond grinding device in the related art has a single rotation direction and needs to manually adjust the position of the diamond continuously when grinding the diamond with a conical structure, resulting in low grinding efficiency.

[0008] A diamond grinding device of the present invention comprises a machine body, a grinding assembly and a clamping assembly arranged on the machine body, wherein a driving assembly for driving the clamping assembly to move closer to or away from the grinding assembly is arranged on the machine body, the clamping assembly comprises a mounting rod, a mounting sleeve sleeved on the outer periphery of the mounting rod, and a clamping member arranged on the mounting sleeve, wherein the clamping member comprises a mounting frame and two clamping parts rotatably connected to the mounting frame; The axial direction of the mounting rod is defined as the left-right direction. The outer periphery of the mounting rod is provided with a mounting collar. The mounting collar is slidably connected with the mounting sleeve along the left-right direction. The mounting collar is connected with a driving component 2 that drives it to move along the left-right direction. A driving structure that drives the mounting collar to rotate is provided between the mounting collar and the mounting rod, and a transmission component is provided between the mounting collar and the clamping portion. When the mounting collar moves in the left and right directions, the driving structure drives the mounting collar to drive the mounting sleeve and the clamping member to rotate around the axis of the mounting rod, and at the same time, the transmission assembly drives the clamping part to rotate around the rotating axis of the clamping part and the mounting frame.

[0009] The clamping part of the present invention can not only rotate around the axis of the mounting rod, but also rotate around the rotation axis of the clamping part and the mounting frame, thereby realizing multi-directional adjustment of the clamped diamond, so that the grinding device of the present invention can be suitable for grinding diamonds of various shapes, and automatically switch the grinding surface, reducing manual participation and improving grinding efficiency.

[0010] Preferably, drive component 2 includes a sliding sleeve and a driving member for driving the sliding sleeve to rotate, the sliding sleeve is sleeved on the outer periphery of the mounting rod, a bidirectional threaded section is provided on the mounting rod, a protrusion cooperating with the bidirectional threaded section is fixedly connected inside the sliding sleeve, the mounting ring is rotatably connected to the sliding sleeve, when the driving member drives the sliding sleeve to rotate, the sliding sleeve moves in the left and right directions with the cooperation of the bidirectional threaded section and the protrusion, and the sliding sleeve drives the mounting ring to move in the left and right directions.

[0011] Preferably, the driving member includes a driving motor and a movable sleeve, the mounting rod and the driving motor are respectively fixedly mounted on a driving component, the movable sleeve is sleeved on the outer periphery of the mounting rod and fixedly connected to the output end of the driving motor, the sliding sleeve is slidingly connected to the movable sleeve along the left and right directions, and when the driving motor drives the movable sleeve to rotate, the movable sleeve drives the sliding sleeve to rotate.

[0012] Preferably, the driving structure includes a mounting plate, a guide groove provided on the mounting plate and a guide block fixedly connected to the mounting ring. The mounting plate is detachably connected to the mounting rod. When the mounting ring moves in the left and right directions, the guide block moves along the guide groove. The guide groove guides the guide block to drive the mounting ring to rotate, and the mounting ring drives the clamping part to rotate. At the same time, the transmission assembly drives the clamping part to drive the diamond to rotate and switch the grinding surface. When the grinding surface is switched, the mounting ring drives the clamping part to rotate until the grinding surface of the diamond is parallel to the grinding disk of the grinding assembly.

[0013] Preferably, the transmission assembly includes a rack and a gear. The rack is fixedly connected to the mounting collar and corresponds to the two clamping parts respectively. The gear is fixedly connected to the rotating shaft that is rotatably connected to the clamping part and the mounting frame. The gear is meshed with the corresponding rack. When the mounting collar moves in the left and right directions, it drives the rack to move synchronously. The rack drives the gear to drive the clamping part to rotate around the axis of the rotating shaft.

[0014] By setting up a driving motor as a driving source, the clamping part can rotate around the axis of the rotating shaft and around the axis of the mounting rod, so that the clamping part can switch the diamond grinding surface and adjust the angle of the diamond grinding surface at the same time, reducing the setting of the driving source and reducing the production cost.

[0016] Preferably, the rack is slidably connected to the mounting collar, and the rack runs through the corresponding mounting block, and when the two mounting blocks move toward or away from each other, the corresponding rack is driven to move synchronously.

[0017] When the two mounting blocks move toward or away from each other, the corresponding racks are driven to move synchronously, ensuring that the racks are always meshed with the gears on the rotating shaft of the clamping column.

[0018] Preferably, the two mounting blocks are respectively provided with clamping plates on one side facing each other, and the clamping plates are elastically connected to the mounting blocks through springs. When the clamping plates are not subjected to external forces, the vertical distance between the two clamping plates is smaller than the vertical distance between the two clamping columns. A pushing structure is provided between the rack and the corresponding clamping plate. When the grinding surface of the diamond is parallel to the grinding disk of the grinding assembly, the pushing structure pushes the clamping plate to clamp the diamond. When the grinding surface of the diamond is switched, the pushing structure cancels the pushing of the clamping plate.

[0019] The push structure pushes the clamping plate to clamp the diamond, which is beneficial to ensure the stability of the diamond during the grinding process. When switching the grinding surface of the diamond, the push structure cancels the push on the clamping plate, which is beneficial to the clamping column driving the diamond to turn over smoothly.

[0020] Preferably, the pushing structure includes a pushing tooth arranged on the rack and a pushing groove arranged on the clamping plate, the pushing teeth are arranged at intervals along the left and right directions, and the left and right side surfaces of the pushing teeth are inclined surfaces, and the pushing grooves are arranged at intervals along the left and right directions. When the rack moves along the left and right directions, the pushing teeth push the edge of the pushing groove through the inclined surface, and the pushing groove drives the clamping plate to move in a direction close to the diamond.

[0021] By configuring the pushing structure to include mutually cooperating pushing teeth and pushing grooves, the pushing of the clamping plate can be achieved as the rack 2 moves, and when the pushing teeth move into the pushing grooves, the pushing of the clamping plate can be cancelled, without the need to separately configure a driving source for the pushing structure.

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figures 1 to 6 As shown, a diamond grinding device of the present invention comprises a body 1, a grinding assembly and a clamping assembly arranged on the body 1, and a driving assembly 1 for driving the clamping assembly to move closer to or away from the grinding assembly is arranged on the body 1.

[0033] The grinding assembly includes a grinding disc 2 and a motor 21 for driving the grinding disc 2 to rotate. The motor 21 is fixedly mounted on the machine body 1. The grinding disc 2 is rotatably connected to the machine body 1 and is fixedly connected to the driving end of the motor 21. The machine body 1 is provided with a mounting groove 22 along the outer periphery of the grinding disc 2. A support rod 23 extending vertically is fixedly mounted in the mounting groove 22. The driving assembly 1 includes an electric push cylinder 24 fixedly mounted on the support rod 23 and a movable block 25 fixedly connected to the driving end of the electric push cylinder 24. The clamping assembly is mounted on the movable block 25. The electric push cylinder 24 drives the movable block 25 to drive the clamping assembly to move in a direction close to or away from the grinding disc 2. The motor 21 drives the grinding disc 2 to rotate, and the diamond 10 contacting the grinding disc 2 is ground.

[0034] The clamping assembly includes a mounting rod 3 fixedly connected to the movable block 25, a mounting sleeve 31 sleeved on the outer periphery of the mounting rod 3, and a clamping member disposed on the mounting sleeve 31. The mounting sleeve 31 is rotatably connected to the mounting rod 3 and cannot move relative to the mounting rod 3 in the axial direction. The clamping member includes a mounting frame 32 and two clamping parts 33 rotatably connected to the mounting frame 32.

[0035] The axial direction of the mounting rod 3 is defined as the left-right direction. A mounting ring is sleeved on the outer periphery of the mounting rod 3. The mounting ring includes a mounting ring 1 41 and a mounting ring 2 42. The mounting ring 1 41 and the mounting ring 2 42 are fixedly connected by a connecting rod 43. The mounting ring 1 41 is sleeved on the outer periphery of the mounting rod 3. The mounting ring 2 42 is fixedly connected with a slider (not shown in the figure). A sliding groove (not shown in the figure) adapted to the slider is opened on the mounting sleeve 31. The mounting ring 2 42 is slidably connected to the mounting sleeve 31 through the cooperation of the slider and the sliding groove.

[0036] The mounting collar 41 is connected to a driving assembly 2 for driving it to move in the left and right directions. A driving structure for driving the mounting collar to rotate is arranged between the mounting collar 41 and the mounting rod 3, and a transmission assembly is arranged between the mounting collar and the clamping portion 33.

[0037] After the diamond 10 is clamped between the two clamping parts 33, the grinding disc 2 is controlled to grind one of the surfaces of the diamond 10. When the grinding is completed and the grinding surface needs to be switched, the mounting collar 1 41 is driven to move rightward by the driving component 2. The mounting collar 1 41 drives the mounting collar 2 42 to move rightward through the connecting rod 43. The mounting collar 2 42 drives the transmission component to drive the clamping part 33 to rotate around the rotating axis of the clamping part 33 and the mounting frame 32, so as to switch the grinding surface of the diamond 10. At the same time, the driving structure is triggered during the movement of the mounting collar 1 41 to the right. The driving structure drives the mounting collar to drive the mounting sleeve 31 and the clamping part to rotate around the axis of the mounting rod 3, so as to adjust the angle of the grinding surface of the diamond 10, so that the grinding surface of the diamond 10 rotates to a state parallel to the grinding disc 2, which is conducive to the smooth progress of the grinding work.

[0038] The clamping portion 33 of the present invention can not only rotate around the axis of the mounting rod 3, but also rotate around the rotation axis of the clamping portion 33 and the mounting frame 32, thereby realizing multi-directional adjustment of the clamped diamond 10, so that the grinding device of the present invention can be suitable for grinding diamonds 10 of various shapes, and automatically switch the grinding surface, reduce manual participation, and improve grinding efficiency.

[0039] The second driving assembly includes a sliding sleeve 5 and a driving member for driving the sliding sleeve 5 to rotate. The sliding sleeve 5 is sleeved on the outer periphery of the mounting rod 3. The mounting rod 3 is provided with a bidirectional threaded section 34. A protrusion (not shown in the figure) that cooperates with the bidirectional threaded section 34 is fixedly connected inside the sliding sleeve 5. The mounting collar 1 41 is rotatably connected to the sliding sleeve 5. The driving member includes a driving motor (not shown in the figure) and a movable sleeve 6. The driving motor is fixedly installed on the movable block 25. The movable sleeve 6 is sleeved on the outer periphery of the mounting rod 3 and is fixedly connected to the output end of the driving motor. A guide rod 61 is fixedly connected to the right end of the movable sleeve 6. The sliding sleeve 5 is slidably connected to the guide rod 61 in the left-right direction. When the driving motor drives the movable sleeve 6 to rotate, the movable sleeve 6 drives the sliding sleeve 5 to rotate through the guide rod 61. The sliding sleeve 5 moves in the left-right direction under the cooperation of the bidirectional threaded section 34 and the protrusion, so that the sliding sleeve 5 drives the mounting collar 1 41 to move in the left-right direction.

[0040] The driving structure includes a mounting plate 7, a guide groove 71 provided on the mounting plate 7, and a guide block (not shown in the figure) fixedly connected to the mounting collar 1 41. The mounting plate 7 is detachably connected to the mounting rod 3 by bolts. When the mounting collar 1 41 moves in the left and right directions, the guide block moves along the guide groove 71. The guide groove 71 guides the guide block to drive the mounting collar 1 41 to rotate. The mounting collar 1 41 drives the mounting collar 2 42 to rotate through the connecting rod 43. The mounting collar 2 42 drives the mounting sleeve 31 and the clamping member to rotate around the axis of the mounting rod 3, so as to adjust the angle of the grinding surface of the diamond 10 so that the grinding surface of the diamond 10 can be parallel to the grinding disc 2.

[0041] The transmission assembly includes a rack 8 and a gear 81. The rack 8 is fixedly connected to the mounting collar 2 42 and corresponds to the two clamping parts 33 respectively. The gear 81 is fixedly connected to the rotating shaft that is rotatably connected to the clamping part 33 and the mounting frame 32. The gear 81 is meshed with the corresponding rack 8. When the mounting collar 2 42 moves in the left and right directions, it drives the rack 8 to move synchronously. The rack 8 drives the gear 81 to drive the clamping part 33 to rotate around the axis of the rotating shaft, thereby realizing the switching of the grinding surface of the diamond 10.

[0042] By setting up a driving motor as a driving source, the clamping part 33 can rotate around the axis of the rotating shaft and around the axis of the mounting rod 3, so that the clamping part 33 can switch the grinding surface of the diamond 10 and adjust the angle of the grinding surface of the diamond 10 at the same time, reducing the setting of the driving source and reducing the production cost.

[0043] In this embodiment, the diamond 10 is described as a regular octahedron. The clamping portion 33 is clamped on two opposite and parallel faces of the diamond 10, and the structure of the guide groove 71 on the mounting plate 7 is adapted to the angle that needs to be adjusted when the grinding surface of the diamond 10 is switched, so that after the grinding surface is switched, the grinding surface is exactly parallel to the grinding disk 2. It can be understood that in other embodiments, for diamonds 10 of different shapes, the mounting plate 7 with the adapted guide groove 71 can be replaced, so that when the clamping portion 33 rotates to switch the grinding surface of the diamond 10, the corresponding guide groove 71 can guide the clamping portion 33 to rotate at a suitable angle around the axis of the mounting rod 3, so as to achieve the effect that the grinding surface is parallel to the grinding disk 2.

[0044] Two mounting blocks 9 are symmetrically arranged on the mounting frame 32, and the two mounting blocks 9 are slidably connected to the mounting frame 32. A lead screw 35 is rotatably connected to the mounting frame 32, and the lead screw 35 is provided with two thread segments with opposite thread rotation directions. The two mounting blocks 9 are respectively threadedly matched with the corresponding thread segments. The clamping part 33 includes a clamping column, and the clamping column is rotatably connected to the corresponding mounting block 9 through a rotating shaft. When the diamond 10 is installed between the two clamping parts 33, the lead screw 35 is manually screwed to adjust the distance between the two mounting blocks 9 so that the clamping column clamps the diamond 10.

[0045] The rack 8 is slidably connected to the mounting collar 2 42 along the radial direction of the mounting collar 2 42, and the rack 8 passes through the corresponding mounting block 9. When the two mounting blocks 9 move toward or away from each other, the corresponding rack 8 is driven to move synchronously to ensure that the rack 8 is always meshed with the gear 81 on the rotating shaft of the clamping column.

[0046] The two mounting blocks 9 are provided with clamping plates 91 on the sides facing each other. The clamping plates 91 are elastically connected to the mounting blocks 9 through springs (not shown in the figure). When the clamping plates 91 are not subjected to external forces, the vertical distance between the two clamping plates 91 is smaller than the vertical distance between the two clamping columns. A push structure is provided between the rack 8 and the corresponding clamping plate 91. When the grinding surface of the diamond 10 is parallel to the grinding disc 2 of the grinding assembly, the push structure pushes the clamping plate 91 to clamp the diamond 10, which is beneficial to ensure the stability of the diamond 10 during the grinding process. When the grinding surface of the diamond 10 is switched, the push structure cancels the push on the clamping plate 91, which is beneficial to the clamping column driving the diamond 10 to turn over smoothly.

[0047] The pushing structure includes a pushing tooth 82 arranged on the rack 8 and a pushing groove 92 arranged on the clamping plate 91. The pushing teeth 82 are arranged at intervals along the left and right directions, and the left and right side surfaces of the pushing teeth 82 are inclined surfaces. The pushing groove 92 is arranged at intervals along the left and right directions. When the rack 8 moves along the left and right directions, the pushing teeth 82 push the edge of the pushing groove 92 through the inclined surface, and the pushing groove 92 drives the clamping plate 91 to move in the direction close to the diamond 10.

[0048] When the rack 8 moves to the right, the right side of the pushing tooth 82 squeezes the edge of the pushing groove 92, so that the clamping plate 91 moves in the direction close to the diamond 10. When the end of the pushing tooth 82 slides out of the pushing groove 92 and contacts the clamping plate 91, the clamping plate 91 clamps the diamond 10 to ensure the stability of the diamond 10 during the grinding process. When the rack 8 continues to move to the right, the pushing tooth 82 enters the next pushing groove 92, and the clamping plate 91 is separated from the pushing of the pushing tooth 82. , moves in the direction away from the diamond 10, thereby canceling the clamping of the diamond 10. At the same time, under the drive of the rack 8, the clamping portion 33 drives the diamond 10 to rotate to switch the grinding surface. In addition, during the switching process, the right side of the push tooth 82 re-squeezes the edge of the push groove 92, so that the clamping plate 91 moves in the direction close to the diamond 10. After the grinding surface switching is completed, the end of the push tooth 82 slides out of the push groove 92 and contacts the clamping plate 91, thereby clamping the diamond 10 again.
