Embodiment 1

[0021] Example 1, see figure 1 , a soft elastic body polishing head, including a rotating shaft 1 connected with a motor, and a polishing head 2 arranged at the other end of the rotating shaft 1, the polishing head 2 is composed of a grinding core 21 fixedly arranged on the rotating shaft and uniformly planted Abrasive grains 22 that enter the surface of the grinding core. The grinding core 21 is made of elastic rubber-plastic material, and the abrasive grains 22 are needle-shaped with their sharp edges facing outward. The polishing head 2 is cylindrical.

[0022] Utilizing the principle of high-voltage electrostatic adsorption and electrostatic sand planting method, the abrasive grains 22 are uniformly implanted on the surface of the grinding core 21 made of EVA material, and the distribution is even and tightly arranged. The selected abrasive grains 22 have basically the same particle size, and have good contour performance. Abrasive grains 22 have sharp edges facing outw...

Embodiment 2

[0029] Example 2, see figure 2 , the polishing head 2 is a conical round head, and all the other are the same as in Embodiment 1.

Embodiment 3

[0030] Embodiment 3, see image 3 , the polishing head 3 is a round cylindrical shape, and the rest are the same as in Embodiment 1.

[0031] The grinding head can also be made into various sizes and shapes to meet the requirements of different grinding pins.

[0032] Compared with the prior art, the grinding core of the present invention adopts EVA rubber and plastic material. EVA has the advantages of good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and is non-toxic, non-absorbent, non-polluting environment, and the grinding core has good softness, which belongs to soft elastic body and has good flexibility to adapt to irregularities. The advantages of curved surface polishing; compared with grinding wheel grinding, the grinding heat is less, the grinding temperature is lower, the workpiece is not easily deformed, and the processed surface is not prone to defects such as overburning and cracks, and it is easy to o...

Abstract

The invention relates to a soft elastomer polishing head which comprises a rotor shaft connected with a motor and a polishing head arranged on the other end of the rotor shaft, and is characterized in that: the polishing head consists of an abrasive core fixedly arranged on the rotor shaft and abrasive particles evenly embedded into the surface of the abrasive core; the material of the abrasive core is elastic rubber plastic; the abrasive particles are acicular and acicular blades thereof face outwards; the abrasive core adopts the material of EVA rubber plastic and the abrasive particles are evenly embedded into the surface of the abrasive core by adopting an electrostatic sand-planting method.

Description

technical field [0001] The invention relates to the technical field of electric polishing machines, in particular to a polishing head used on the electric polishing machine. Background technique [0002] At present, the polishing heads used in the electric polishing machine market are divided into two types: hard grinding heads and soft grinding heads. The material used for the hard grinding head is the same as that of the ordinary grinding wheel, and the amount of grinding removal during grinding is relatively large, and it is usually used for general surface processing. The soft grinding head uses rubber as the grinding core. Grinding removes less and is often used for surface finishing. It is suitable for surface finishing in machinery, hardware, automobile, mold and other manufacturing industries, such as: grinding, surface finishing, finishing, etc. [0003] Most of the rubber used in the grinding core of the current soft grinding head is relatively hard and has a la...
