Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding disc with chamfered corners. Background Art

[0002] The grinding disc is a carrier for coating or embedding abrasives, so that the abrasive particles can play a cutting role. At the same time, it is also a forming tool for the grinding surface. Rotating discs, cylinders, cones, flat plates, oilstones, thin plates, tubes, rings and specially made shaped grinding discs can all be used as grinding tools.

[0003] In Chinese Patent 202021670425.0, the utility model discloses a grinding disc, which relates to the technical field of grinding equipment. The grinding disc of the utility model includes a grinding disc body, and a plurality of radially extending hammers are fixed on the peripheral side of the grinding disc body, and a hammer piece is fixed on the hammer head, and the hammer piece is detachably connected to the hammer head. The utility model adopts hammer heads that extend circumferentially, which increases the stirring force of the material by the rotation of the grinding disc body, increases the shear force between the material and the hammer head, and thus increases the grinding efficiency. At the same time, the hammer piece and the hammer head are not an integrated structure, so it is not easy to generate heat accumulation, which is conducive to timely heat dissipation.

[0004] When the existing grinding disc is stamped, the small particles on the side will be cut into sharp irregular shapes, which can easily cause scratches when the operator accidentally touches them with his hands. There is also the risk of these small particles falling off. If they are put into use directly, it may cause more foreign matter on the workpiece or even the production line. In addition, when the grinding disc is working, it will generate large vibrations. When other parts hit the grinding disc, it is easy to damage the grinding disc and reduce its working efficiency. At the same time, the grinding disc may fall off due to insufficient clamping force when working.

[0005] Therefore, a chamfered grinding disc is proposed to solve the above problems. Utility Model Content

If they are put into use directly, it may cause more foreign matter to appear on the workpiece or even the production line. In addition, when the grinding disc is working, it will produce a large vibration. When other parts hit the grinding disc, it is easy to damage the grinding disc and reduce its working efficiency.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1 and Figure 5 As shown, a chamfered grinding disc comprises a chamfered grinding disc anti-skid grinding component 1, and a grinding disc anti-collision and shock absorbing component 2 is arranged on the side of the chamfered grinding disc anti-skid grinding component 1;

[0027] The chamfering grinding disc anti-skid grinding assembly 1 includes a chamfering grinding disc body 101, a grinding layer 102, a friction-increasing ball 103, and an anti-skid protrusion block 104. The top of the chamfering grinding disc body 101 is fixedly connected to the grinding layer 102, and the top of the grinding layer 102 is fixedly connected to the friction-increasing ball 103, and the bottom of the chamfering grinding disc body 101 is fixedly connected to the anti-skid protrusion block 104.

[0028] See also Figures 2 to 4 As shown, a chamfered grinding disc is provided, and a forty-five-degree chamfer is provided on the side of the chamfered grinding disc body 101. An inclined surface is cut on the round edge of the chamfered grinding disc body 101 to form a chamfer, and excess burrs and burrs are removed to keep it smooth, which can reduce foreign matter in the production line and solve subsequent production problems caused by foreign matter. The chamfer can also avoid scratches caused by the sharp edges of the original device and reduce the probability of accidents. The friction-increasing balls 103 of alumina material are arranged at equal intervals on the surface of the grinding layer 102. The grinding layer 102 made of alumina material has the characteristics of high hardness, high density, low wear, smooth surface, and corrosion resistance. The friction-increasing balls 103 of alumina are the most ideal grinding-resistant medium for grinding glazes, blanks and various powder materials. The anti-slip protrusions 104 made of silicone material are arranged in a cone shape, which can increase the friction between the bottom and the contact surface when the chamfered grinding disc body 101 shakes during operation to prevent it from falling off during operation.

[0029] See also Figure 1 and Figure 5 As shown, a chamfered grinding disc, the grinding disc anti-collision and shock-absorbing component 2 includes a shock-absorbing circular pad 201, a buffer spring 202, and a limiting rod 203. The shock-absorbing circular pad 201 has elastic force through the buffer spring 202, and the limiting rod 203 is made of rubber material. The shock-absorbing circular pad 201 made of air cushion material has good tensile strength and wear resistance, and also has high hardness and strong shock resistance, which can better buffer the vibration of the chamfered grinding disc body 101 during operation. When external impact force acts on the chamfered grinding disc body 101, the shock-absorbing circular pad 201 plus the buffer spring 202 can slow down the impact of the impact force on the chamfered grinding disc body 101, reduce the influence of the impact force on the chamfered grinding disc body 101, and extend the service life of the chamfered grinding disc body 101.

[0030] Working principle: First, the side of the chamfered grinding disc body 101 is provided with a 45-degree chamfer, and the redundant burrs and burrs of the entire device are removed to keep it smooth, which can reduce foreign matter in the production line and solve the subsequent production problems caused by foreign matter. The chamfer can also avoid the problem of scratches on personnel caused by the sharp edge of the original device, and reduce the probability of accidents. Alumina has the characteristics of high hardness, high density, low wear, smooth surface, and corrosion resistance. The grinding layer 102 made of it can be resistant to grinding and can reduce foreign matter on the production line to a certain extent. The anti-slip protrusion 104 of the silicone material is in the shape of a cone, which can increase the friction between the bottom and the contact surface when the chamfered grinding disc body 101 is shaking during operation, so as to prevent it from falling off during operation;

[0031] Next, when an external impact force acts on the chamfering grinding disc body 101, the shock-absorbing circular pad 201 can buffer the impact force through the buffer spring 202. Since the elastic force direction of the buffer spring 202 is not unique, the limiting rod 203 made of rubber material can play a certain supporting role. At the same time, the shock-absorbing circular pad 201 made of air cushion material can slow down the impact of the impact force on the chamfering grinding disc body 101, reduce the impact of the impact force on the chamfering grinding disc body 101, and extend the service life of the chamfering grinding disc body 101.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
