Motorized spindle grinding head

Abstract

The invention discloses a motorized spindle grinding head which comprises a grinding head seat, a grinding head shaft, a grinding wheel and a feeding device. The grinding wheel is fixedly mounted on the grinding head shaft, the motorized spindle grinding head further comprises a sliding sleeve, a stator and a rotor, the grinding head seat is arranged on the outer wall of the sliding sleeve in a sleeving mode, the sliding sleeve and the grinding head seat axially slide and are in circumferential clamping connection, and the grinding head shaft and the sliding sleeve are rotationally connected and are in axial clamping connection. The grinding head shaft coincides with the axis of the sliding sleeve, the rotor is fixedly connected with the grinding head shaft, the stator is fixedly connected with the sliding sleeve and generates a magnetic field driving the rotor to rotate, the stator and the rotor are both located in the sliding sleeve, and the feeding device is connected to the grinding head base and the sliding sleeve. The motorized spindle grinding head has the beneficial effects that the situation that feeding cannot be achieved due to resistance between the sliding sleeve and the grinding head shaft is prevented, and the effect of improving reliability is achieved. Fewer materials are used, a motor and a coupler on an output shaft of the motor do not need to be installed, the materials needing to be used are reduced, the structure is simpler, and better performance can be achieved.

Description

technical field [0001] The invention relates to the technical field of grinding heads, in particular to an electric spindle grinding head. Background technique [0002] In order to improve the gloss and dimensional accuracy of ceramic tiles, cement bricks, foam bricks and refractory bricks, it is often necessary to use an edge grinder to drive the grinding head to grind ceramic tiles, floor tiles and wall tiles. Edging machine is an important part of porcelain tile polishing and edging production line. The edging head is the core component of the edging machine, and its technical performance is directly related to the quality of edging and production efficiency. [0003] At present, the structure of the conventional edging grinding head is as follows: figure 1 As shown, it consists of two parts, the front part is the working part 61, which we call the grinding head part, and the rear part is the power part 62, which is a general-purpose conventional motor. The motor with th...

[0003] At present, the structure of the conventional edging grinding head is as follows: figure 1 As shown, it consists of two parts, the front part is the working part 61, which we call the grinding head part, and the rear part is the power part 62, which is a general-purpose conventional motor. The motor with this structure is a general-purpose product, and it is easy to damage after use replace

But there are also the following disadvantages: 1. The center of gravity of the motor is suspended outside the fulcrum of the support. The greater the power, the greater the weight of the motor, the greater the length of the overhang, and the greater the torque generated, the feed adjustment resistance will be greatly increased. When it exceeds a certain range, the thrust of the feeding device will not be able t
