Inner dust suction device for internal grinding of metal pipe materials

Abstract

The invention relates to the technical field of metal pipe material processing equipment, in particular to an inner dust suction device for internal grinding of metal pipe materials. The inner dust suction device comprises a pipe body, a high-speed motor, an abrasive wheel and a transmission long shaft, wherein the transmission long shaft is axially and fixedly connected with the high-speed motor; a fixing mounting seat is arranged at an opening position in the right side of the pipe body; a power groove for allowing the high-speed motor to be mounted is formed in the fixing mounting seat; and the high-speed motor is fixedly connected with the fixing mounting seat by being clamped in the power groove. According to the inner dust suction device for the internal grinding of the metal pipe materials, a dust collecting box in which a vacuumizing pump housing is arranged is fixed to the right side of the fixing mounting seat, a vane wheel is axially connected with the high-speed motor by a coupling, and the vane wheel and the abrasive wheel are synchronously driven to rotate by the high-speed motor, so that the purpose that a dust suction and heat dissipating device is started while the burnishing is performed is achieved, high temperature and flying dust in the pipe materials can be quickly pumped away from the inner parts of the pipe materials, the service life of a burnishing device is greatly prolonged, and the burnishing effects are greatly improved.

Description

technical field [0001] The invention relates to the technical field of metal pipe processing equipment, in particular to an internal dust suction device for internal rounding of metal pipes. Background technique [0002] In the internal grinding equipment for metal pipe workpieces, the existing technology is to connect the motor and the grinding wheel through the long transmission shaft, and the motor drives the long transmission shaft to rotate to realize the rotation of the grinding wheel, and to grind the inner wall of the metal pipe workpiece. , in order to achieve a better grinding effect, the speed of the motor is usually higher, that is, the working state of the long drive shaft and the grinding wheel is high-speed rotation during the grinding process, and the long drive shaft is rotating at high speed, and the grinding wheel is also on the inner wall of the pipe. High-speed friction will generate a lot of flying debris and high temperature inside. If the flying debri...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problems in the above-mentioned background technology, an improved internal dust suction device for internal grinding of metal pipes is provided, which solves the problem that the grinding wheel is also damaged when the long axis of transmission rotates at high speed High-speed friction on the inner wall of the pipe will generate a large amount of flying debris and high temperature inside. If the flying debris cannot be cleaned in time, it will easily stick to the surface of the pipe, resulting in poor grinding effect, and the internal high temperature will also aggravate the deformation of the grinding wheel and the long axis of the transmission.
