Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel slotting, in particular to a grinding wheel slotting device. Background Art

[0002] Grinding wheel grooving uses a high-speed rotating grinding wheel as a cutting tool. Under the combined action of centrifugal force and the driving force of the motor body, the abrasive particles on the surface of the grinding wheel impact and grind the workpiece surface at an extremely high speed, removing the workpiece material according to a predetermined trajectory, thereby processing a groove with specific shape, size and precision requirements on the workpiece.

[0003] At present, the grinding wheel in the existing grinding wheel grooving device is very easy to vibrate when rotating at high speed. The reasons are as follows: first, it is difficult to achieve absolute uniform distribution of quality during the manufacturing process of the grinding wheel; second, it is also difficult to ensure its perfect concentricity when installing the grinding wheel; and the existing grinding wheel grooving device lacks effective balancing measures, resulting in vibrations that not only reduce the accuracy of grooving, make the groove wall rough and uneven in size, but also accelerate the wear of components such as the grinding wheel and the rotating shaft. Therefore, the present application provides a grinding wheel grooving device to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a grinding wheel slotting device to solve the problem that the grinding wheel in the existing grinding wheel slotting device is very easy to vibrate when rotating at high speed and lacks balancing measures.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A grinding wheel grooving device comprises: a motor body; a support member, arranged at the bottom of the motor body, and used to drive the motor body to perform lifting and lowering movements; a rotating rod, one end of which is arranged on the output end of the motor body; a grinding wheel body, arranged on the rotating rod; a fixing ring, arranged on the rotating rod and located at one end of the grinding wheel body, and used to fix the grinding wheel body; a balancing ring, arranged on the rotating rod and located at the other end of the grinding wheel body; a limiting ring, arranged on the rotating rod and in contact with the balancing ring; a gasket, arranged on the rotating rod and located between the grinding wheel body and the balancing ring; a placement cavity, arranged in the balancing ring and in an annular shape; and a balancing medium, filled and arranged in the placement cavity.

[0007] Preferably, the balance ring is made of stainless steel, and the surface of the balance ring is coated with an elastic rubber coating.

[0008] Preferably, a plurality of elastic rubber blocks are arranged on the edges of both ends of the gasket and are distributed in a circumferential manner; the gasket is made of a material with high heat resistance, low friction coefficient and good wear resistance.

[0009] Preferably, a plurality of elastic strips are arranged in the gasket, and the elastic strips are honeycomb-shaped.

[0010] Preferably, a protective member is arranged above the motor body to block grinding debris during grooving.

[0011] Preferably, a three-jaw chuck is provided at one end of the support member to fix the workpiece; and a moving member is provided on the three-jaw chuck to drive the three-jaw chuck to telescope.

[0012] Preferably, a workbench is arranged at the bottom of the moving member, and is used to drive the moving member to move forward and backward.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

[0014] In the above scheme, by setting a balance ring, when the center of gravity of the grinding wheel shifts due to uneven quality during the manufacturing process, the balancing medium can flow in the annular cavity under high-speed rotation, and offset the unbalanced force of the grinding wheel by redistributing itself. The surface of the balance ring is coated with an elastic rubber coating. When the grinding wheel is installed slightly eccentrically, the elastic rubber coating can play a role of buffering and adaptive adjustment, thereby reducing the vibration caused by the eccentric installation.

[0015] By setting the gasket, the high temperature generated during the grinding wheel cutting process can be tolerated and the friction between the grinding wheel body and the gasket can be reduced. By setting the elastic strip, the vibration energy generated by the rotation of the grinding wheel can be absorbed and dispersed in multiple directions. The elastic rubber block can fit closely to the edge of the grinding wheel to further prevent the transmission of vibration. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0025] like Figure 1 - Figure 6 As shown, an embodiment of the utility model provides a grinding wheel grooving device, comprising: a motor body 2; a support member 1, arranged at the bottom of the motor body 2, and used to drive the motor body 2 to perform lifting and lowering movements; a rotating rod 21, one end of which is arranged on the output end of the motor body 2; a grinding wheel body 9, arranged on the rotating rod 21; a fixing ring 8, arranged on the rotating rod 21, and located at one end of the grinding wheel body 9, and used to fix the grinding wheel body 9; a balancing ring 7, arranged on the rotating rod 21, and located at the other end of the grinding wheel body 9; a limiting ring 22, arranged on the rotating rod 21, and in contact with the balancing ring 7; a gasket 10, arranged on the rotating rod 21, and located between the grinding wheel body 9 and the balancing ring 7; a placement cavity 71, arranged in the balancing ring 7, and in an annular shape; a balancing medium 72, filled and arranged in the placement cavity 71.

[0026] The balancing medium 72 can be made of, for example, oil or special balancing beads, and the balancing ring 7 is sealed, with the weight being biased on one side of the grinding wheel body 9, generating a centrifugal force toward the center of gravity of that side, and the balancing medium 72 will gather in the opposite direction, and use the redistribution of its own mass to offset the unbalanced centrifugal force of the grinding wheel body 9, thereby achieving dynamic balance and suppressing vibration; by setting the support 1, a hydraulic lifting structure can be adopted, which consists of a hydraulic cylinder, a piston rod and a hydraulic control system, and the hydraulic oil is transported from the oil tank to one side chamber of the hydraulic cylinder by a hydraulic pump, so that the piston rod is extended and the motor body 2 rises; when the motor body 2 needs to descend, the flow direction of the hydraulic oil is changed, so that the hydraulic oil flows out from the other side chamber and the piston rod is retracted; or an electric push rod structure is adopted, the electric push rod is extended to drive the motor body 2 to rise, and the electric push rod is retracted to drive the motor body 2 to descend; the motor body 2 is powered by an external power supply.

[0027] The balance ring 7 is made of stainless steel, and the surface of the balance ring 7 is coated with an elastic rubber coating. The balance ring 7 is made of stainless steel, which has high strength and hardness, and can withstand the huge centrifugal force and other complex forces generated by the grinding wheel when it rotates at high speed; the elastic rubber coating can play a buffering role, absorb and attenuate vibration energy, and reduce the vibration transmitted from the grinding wheel to the balance ring 7; first install the balance ring 7 on the rotating rod 21, limit its installation position by the limit ring 22, then install the gasket 10 on the rotating rod 21, install the grinding wheel body 9 on the rotating rod 21, and finally fix it by the fixing ring 8.

[0028] Several elastic rubber blocks 101 are arranged at the edges of both ends of the gasket 10 and are distributed in a circular pattern; the gasket 10 is made of a material with high heat resistance, low friction coefficient and good wear resistance. By setting the elastic rubber blocks 101, the transmission of vibration between the grinding wheel body 9 and the balance ring 7 can be reduced, so that the vibration energy is initially attenuated during the transmission process. At the same time, during the operation, due to factors such as temperature changes and slight deformation of components, the relative position between the grinding wheel body 9 and the balance ring 7 may change slightly. The elasticity of the elastic rubber blocks 101 can make it adapt to this position change and always maintain a good contact state; the gasket 10 can be made of materials such as polytetrafluoroethylene, ceramic fiber composite materials or high-temperature nylon. When performing continuous high-intensity grooving operations, the gasket 10 will not lose its elasticity due to high temperature, thereby maintaining the ability to absorb and disperse vibrations, and reducing the friction between the grinding wheel body 9 and the gasket 10.

[0029] A plurality of elastic strips 102 are arranged in the gasket 10, and the elastic strips 102 are honeycomb-shaped. By arranging the elastic strips 102 in a honeycomb shape, when the grinding wheel body 9 vibrates, the vibration wave will be transmitted to the gasket 10 from all directions, and the honeycomb-shaped elastic strips 102 can buffer the vibration in multiple directions at the same time, and each honeycomb unit can be regarded as an independent elastic structure, which can withstand and disperse the vibration energy in different angles and directions.

[0030] The protective member 3 is arranged above the motor body 2 and is used to block the grinding debris during the slotting. By setting the protective member 3, a large amount of grinding debris will be generated during the slotting process of the grinding wheel. The protective member 3 can effectively block these debris and prevent them from splashing toward the motor body 2; it includes a protective cover, the protective cover is provided with a connecting rod, a mounting plate is provided on the motor body 2, a moving frame is provided on the mounting plate, a screw rod is provided in the moving frame, a slider is provided on the screw rod, the slider is connected to the connecting rod, the slider is driven to move by the rotation of the screw rod, and the connecting rod moves synchronously, thereby adjusting the height of the protective cover, and a cylinder can also be used, the cylinder is connected to the connecting rod, and the cylinder is extended and retracted to drive the connecting rod to move synchronously, thereby adjusting the height of the protective cover.

[0031] The three-jaw chuck 4 is arranged at one end of the support member 1 and is used to fix the workpiece; the moving member 5 is arranged on the three-jaw chuck 4 and is used to drive the three-jaw chuck 4 to move telescopically. By setting a three-jaw chuck 4, the workpiece can be firmly fixed on the chuck to prevent the workpiece from being displaced during the grooving process of the grinding wheel; by setting a moving part 5, including a connecting tube, a cylinder is set in the connecting tube, the cylinder is connected to the three-jaw chuck 4, and the three-jaw chuck 4 is driven to extend and retract through the operation of the cylinder to adjust the position of the workpiece; manual adjustment can also be adopted, including a connecting tube, a mounting tube is set on the connecting tube, a threaded rod is set in the mounting tube, a first gear is set at the bottom of the threaded rod, two racks are slidably set in the connecting tube, one end of the rack is connected to the three-jaw chuck 4, an adjusting gear is set to mesh between the racks, the adjusting gear is connected to a rotating rod, one end of the rotating rod extends into the mounting tube and a second gear is set, the first gear and the second gear are meshed, and by rotating the threaded rod, the first gear and the second gear cooperate to make the rotating rod rotate, drive the adjusting gear to rotate, so that the rack moves, thereby pushing the three-jaw chuck 4 to move and adjust the position of the workpiece.

[0032] The workbench 6 is arranged at the bottom of the moving part 5, and is used to drive the moving part 5 to move forward and backward. A mounting frame is arranged at one end of the workbench 6, and a stepper motor is arranged in the mounting frame. The output end of the stepper motor is connected to a lead screw, and one end of the lead screw extends into the workbench 6. A slider is threadedly sleeved on the lead screw, and the slider is connected to the moving part 5. The stepper motor rotates to drive the lead screw to rotate, so that the slider moves synchronously, so that the moving part 5 moves, so as to adjust the front and rear position of the moving part 5; an electric slide rail can also be arranged in the workbench 6, and the electric slide rail is connected to the moving part 5, and the moving part 5 is driven to move by the electric slide rail.

[0033] The technical solution provided by the utility model is that when in use, the workpiece is clamped by the three-jaw chuck 4, the height of the motor body 2 is adjusted by the support member 1, and then the height of the grinding wheel body 9 is adjusted to correspond to the position of the workpiece to be grooved, and after the protective member 3 is adjusted to the appropriate position, the motor body 2 is turned on to drive the rotating rod 21 to rotate, so that the grinding wheel body 9 rotates synchronously to perform the groove operation; when the grinding wheel body 9 produces a center of gravity shift under high-speed rotation, thereby causing an unbalanced centrifugal force, the balancing medium 72 will flow in the placement cavity 71 according to the change of the centrifugal force, and redistribute to offset the unbalanced force, thereby reducing vibration, and at the same time, when the grinding wheel body 9 vibrates, the vibration wave is transmitted to the gasket 10, and the elastic strip 102 uses its own elastic deformation to disperse and transform the vibration energy to prevent the vibration from further propagating, and after the groove is completed, the motor body 2 is closed and the processed workpiece is removed.
