Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and in particular to an abrasive self-cleaning grinding wheel. Background Technology

[0002] Grinding wheels are a common type of grinding equipment, widely used in machining, metal manufacturing, woodworking, casting and cleaning. A benchtop grinding wheel is an electric grinding tool fixed on a workbench, mainly used for sharpening cutting tools and tools (such as lathe tools and drill bits), and can also be used for cutting, grinding, polishing and deburring materials such as metal, wood, glass and gemstones.

[0003] In existing technologies, during grinding, especially when grinding soft materials (such as aluminum alloys, copper alloys, certain plastics, and wood) or materials that produce sticky chips, the chips, dust, and the material being ground itself easily clog the pores and abrasive gaps on the grinding wheel surface. The clogged grinding wheel surface becomes smooth, reducing the effective cutting abrasive grains and drastically decreasing the cutting ability. It requires a longer processing time to achieve the desired effect. Furthermore, clogging increases grinding force, which can easily cause workpiece surface burns, vibration marks, and difficulty in controlling dimensional accuracy, affecting the surface finish of the machined material. Currently, the main solution to the grinding wheel clogging problem relies on manual cleaning. Operators periodically stop the equipment and manually clean the grinding wheel surface using specialized cleaning tools (such as diamond dressing pens, carbide scrapers, and wire brushes). This method is inefficient, time-consuming, labor-intensive, and increases labor costs. Moreover, the cleaning effect depends on the operator's experience, and incomplete cleaning or improper operation may damage the grinding wheel. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-cleaning abrasive grinding wheel machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an abrasive self-cleaning grinding wheel machine, comprising a grinding wheel machine body, with grinding wheels rotatably connected to both ends of the grinding wheel machine body, a grinding wheel cover provided on the surface of the grinding wheel, the grinding wheel cover being fixed to both ends of the grinding wheel machine body respectively, a cylinder fixed on the surface of the grinding wheel machine body, a connecting seat fixed at the output end of the cylinder, a connecting rod detachably connected to both ends of the connecting seat, and a cleaning clamp fixed on one side of the connecting rod.

[0006] Preferably, the inner wall of the connecting seat has a slot on the side near the connecting rod, and each slot has a limiting groove on its side wall. Limiting sliders are slidably connected to both ends of the limiting grooves. Limiting springs are fixed between the ends of the limiting sliders on the same side that are far apart from each other and the inner wall of the limiting groove. Limiting rollers are provided between the limiting sliders on opposite sides. A plug is fixed to the end of the connecting rod near the connecting seat. After prolonged use, the cleaning clamp suffers significant wear due to friction, requiring regular maintenance and replacement. To address this issue, this invention adopts a detachable structure. When the cleaning clamp needs maintenance or replacement, the connecting rod is pulled outwards to remove the cleaning clamp. During installation, the connecting rod is inserted into the connecting seat, allowing the plug to be inserted into the slot. The plug presses against the limiting roller and the limiting spring. Once the plug is fully inserted into the slot, the limiting spring provides support, causing the limiting roller to lock the plug. This design is simple to install and remove, saving time and effort.

[0007] Preferably, a shock-absorbing base is nested at the bottom of the grinding wheel body, and a forward rotating seat is fixed on the surface of the grinding wheel body. Support rods are rotatably connected to both ends of the forward rotating seat, and a side rotating seat is rotatably connected to the end of the support rod away from the forward rotating seat. A damping spring shock absorber is fixed to the side of the side rotating seat. Existing benchtop grinding wheels generate significant vibration during operation. To address this problem, this invention employs a shock-absorbing mechanism. When the grinding wheel vibrates, it drives the forward rotating seat and support rods to push the damping spring shock absorber. When the spring inside the shock absorber is subjected to external impact or vibration, it undergoes compression or stretching deformation, converting the kinetic energy of the impact into elastic potential energy for storage. When the external force disappears, the spring releases the stored energy through elastic recovery. The flow resistance of the medium inside the shock absorber or the friction of the friction plates generates a damping force opposite to the direction of motion. The damper converts the kinetic energy released by the spring into heat energy, thereby rapidly consuming vibration energy, reducing vibration, and improving machining accuracy.

[0008] Preferably, the limiting roller and the limiting slider are fixedly connected, which improves the engagement force between the limiting roller and the plug.

[0009] Preferably, the bottom of the grinding wheel body and the shock-absorbing base are slidably connected, which improves the stability of the grinding wheel.

[0010] Preferably, both sides of the plug end are curved to facilitate insertion of the plug into the slot.

[0011] Preferably, the inner wall of the cleaning clamp is fixed with a copper wire brush with moderate hardness, which will not scratch the metal surface of the grinding wheel and is suitable for cleaning stubborn abrasive residues.

[0012] Beneficial effects

[0013] In existing technologies, during grinding, especially when grinding soft materials or materials that produce sticky chips, the grinding debris, dust, and the material being ground itself easily clog the pores and abrasive gaps on the grinding wheel surface. A clogged grinding wheel surface becomes smooth, reducing the effective cutting abrasive grains and drastically decreasing cutting ability, requiring longer processing times to achieve the desired effect. Furthermore, clogging increases grinding force, easily causing workpiece surface burns, chatter marks, and difficulty in controlling dimensional accuracy, ultimately affecting the surface finish. Currently, solving the grinding wheel clogging problem mainly relies on manual cleaning, which requires operators to... The traditional method of manually cleaning the grinding wheel surface using specialized cleaning tools after periodic equipment shutdown is inefficient, time-consuming, labor-intensive, and increases labor costs. Furthermore, the cleaning effect depends on the operator's experience, and incomplete cleaning or improper operation may damage the grinding wheel. To address these issues, this invention employs an automatic cleaning structure. When it is necessary to clean the abrasive from the grinding wheel surface, the cylinder drives the connecting seat to move towards the grinding wheel until the cleaning clamp and the grinding wheel are in contact. Then, the grinding wheel is opened to contact the cleaning clamp, and the abrasive is cleaned through friction. This method is not only simple to operate but also highly efficient, saving time and labor, and reducing labor costs. Attached Figure Description

Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0025] Reference Figure 1-6 A self-cleaning abrasive grinding wheel machine includes a grinding wheel machine body 1, with grinding wheels 2 rotatably connected to both ends of the grinding wheel machine body 1. Grinding wheel covers 4 are provided on the surface of the grinding wheel 2 and are respectively fixed to both ends of the grinding wheel machine body 1. A cylinder 7 is fixed to the surface of the grinding wheel machine body 1, and a connecting seat 6 is fixed to the output end of the cylinder 7. A connecting rod 8 is detachably connected to both ends of the connecting seat 6. A cleaning clamp 5 is fixed to one side of the connecting rod 8. A copper wire brush with moderate hardness is fixed to the inner wall of the cleaning clamp 5, which will not scratch the metal surface of the grinding wheel machine and is suitable for cleaning stubborn abrasive residues.

[0026] A slot 601 is provided on the inner wall of the connector 6 near the connecting rod 8. Each side wall of the slot 601 is provided with a limiting groove 6011. Both ends of the limiting groove 6011 are slidably connected to limiting sliders 11. Limiting springs 12 are fixed between the ends of the limiting sliders 11 on the same side that are far apart from each other and the inner wall of the limiting groove 6011. A limiting roller 9 is provided between the limiting sliders 11 on opposite sides. The limiting roller 9 and the limiting slider 11 are fixedly connected, which improves the biting force between the limiting roller 9 and the plug 10. A plug 10 is fixed to one end of the connecting rod 8 near the connecting seat 6. Both sides of the plug 10 end are designed with arc surfaces to facilitate insertion of the plug 10 into the slot 601. After long-term use, the cleaning clamp 5 suffers significant wear due to friction, thus requiring regular maintenance and replacement. To address this issue, this utility model adopts a detachable structure. When the cleaning clamp 5 needs maintenance or replacement, the connecting rod 8 is pulled outward to remove the cleaning clamp 5. During installation, the connecting rod 8 is inserted into the connecting seat 6, allowing the plug 10 to be inserted into the slot 601. The plug 10 presses against the limiting roller 9 and the limiting spring 12. After the plug 10 is fully inserted into the slot 601, the limiting spring 12 provides support, causing the limiting roller 9 to lock the plug 10 in place. This design simplifies disassembly and assembly, saving time and effort.

[0027] A shock-absorbing base 3 is nested at the bottom of the grinding wheel body 1. A forward rotating seat 13 is fixed on the surface of the grinding wheel body 1. Support rods 14 are rotatably connected to both ends of the forward rotating seat 13. A side rotating seat 15 is rotatably connected to the end of the support rod 14 away from the forward rotating seat 13. A damping spring shock absorber 16 is fixed on the side of the side rotating seat 15. Existing benchtop grinding wheels generate significant vibrations during operation. To address this issue, this invention employs a shock-absorbing mechanism. When the grinding wheel vibrates, it drives the forward rotating seat 13 and support rods 14 to push the damping spring shock absorber 16. When the spring inside the shock absorber is subjected to external impact or vibration, it undergoes compression or stretching deformation, converting the kinetic energy of the impact into elastic potential energy for storage. When the external force disappears, the spring releases the stored energy through elastic recovery. The flow resistance of the medium inside the shock absorber, such as oil or gas, or the friction of the friction plates, generates a damping force opposite to the direction of motion. The damper converts the kinetic energy released by the spring into heat energy, thereby rapidly consuming vibration energy, reducing vibration, and improving machining accuracy. The bottom of the grinding wheel body 1 and the shock-absorbing base 3 are slidably connected, which improves the stability of the grinding wheel.

[0028] The working principle of this utility model is as follows: When it is necessary to clean the abrasive on the surface of the grinding wheel 2, the cylinder 7 is opened to drive the connecting seat 6 to move towards the grinding wheel 2 until the cleaning clamp 5 and the grinding wheel 2 are in contact. Then, the grinding wheel 2 and the cleaning clamp 5 are opened to contact each other, and the abrasive is cleaned by friction. When it is necessary to repair or replace the cleaning clamp 5, the connecting rod 8 is pulled outward to remove the cleaning clamp 5. During installation, the connecting rod 8 is inserted into the connecting seat 6, so that the plug 10 is inserted into the slot 601. The plug 10 squeezes the limiting roller 9 and the limiting spring 12. After the plug 10 is fully inserted into the slot 601, the limiting spring 12 provides support. When the grinding wheel vibrates, it drives the rotating seat 13 and the support rod 14 to push the damping spring shock absorber 16. When the spring inside the shock absorber is subjected to external impact or vibration, it will undergo compression or stretching deformation, converting the kinetic energy of the impact into elastic potential energy and storing it. When the external force disappears, the spring will release the stored energy through elastic recovery. The flow resistance of the medium inside the shock absorber, such as oil or gas, or the friction of the friction plate, generates a damping force in the opposite direction of motion. The damper converts the kinetic energy released by the spring into heat energy, thereby quickly consuming the vibration energy and reducing the vibration.
