Problems solved by technology

Therefore, the existing technology uses a mechanical transmission structure to drive the entire motor (and the grinding wheel installed on the motor) to move up and down, which not only makes the machine structure complicated, but also greatly increases the cost of the machine, and because each machine needs to be equipped with ten Several motors, so the volume of the whole machine is greatly increased and affects the appearance of the machine
Another one, it is difficult to control the working pressure between each grinding wheel and the processed surface by using a mechanical transmission mechanism, so that the processed surface roughness and bright effect cannot meet the requirements

Embodiment Construction

[0013] see Figure 1-3 The grinding head motor shown includes a housing 1, a stator winding 2, a rotor winding 3, a main shaft 4, a rotary sleeve 7, an axial movement driving mechanism 5, a grinding tool (ie, a grinding wheel, not shown) and the like. The axial movement driving mechanism 5 includes a support base 13 forming a rotation pair with the main shaft, and a linear motion mechanism 11 connected to the support base for driving the support base to move axially along the main shaft. The linear motion mechanism 11 includes a cylinder (active element) 6 , a swing plate 8 , a guide pin 9 , and a revolving pin 10 .

[0014] The two ends of the rotary sleeve 7 are rotatably arranged on the housing through two rolling bearings 15 . The rotor winding 3 is fixed on the outer periphery of the rotating sleeve 7, opposite to the stator winding 2 arranged in the casing.

[0015] Two self-lubricating shaft sleeves 16 are fixed in the inner holes at both ends of the rotary sleeve 7 ....

Abstract

The invention provides a grinding head motor which has simple structure, small volume and low cost, wherein, the pressure between a grinding tool and a machined surface can be controlled to obtain better machining effect. The grinding head motor comprises a shell, a stator winding, a rotor winding and a main shaft, wherein, the grinding tool is arranged on the main shaft, and a rotating sleeve isrotatablely arranged on the shell; the rotor winding is fixed on the rotating sleeve; and the main shaft is connected with the rotating sleeve through a sliding pair. The grinding head motor further comprises an axial movement driving mechanism for driving the main shaft to axially move relative to the rotating sleeve.

Description

technical field [0001] The invention relates to a grinding head motor used for grinding and polishing materials such as stone and glass. Background technique [0002] The used motors of polishing machines and edging machines in the market are common motors, and grinding wheels (grinding tools) are installed on the main shaft of common motors to form grinding head motors to carry out processing operations. Because of the special needs of polishing and edging, it is required that the grinding wheel can be stretched (displaced) and independently controlled. Therefore, the existing technology uses a mechanical transmission structure to drive the entire motor (and the grinding wheel installed on the motor) to move up and down, which not only makes the machine structure complicated, but also greatly increases the cost of the machine, and because each machine needs to be equipped with ten Several motors, so the volume of the whole machine is greatly increased and affects the appea...
