Abstract

The invention relates to the technical field of rust removing and polishing of inner walls of various pipes, in particular to a rust removing and polishing device for the inner wall of a magnetic conductive pipe. The rust removing and polishing device comprises a unit body, a rust removing device, a guide device and a control system, wherein the rust removing device, the guide device and the control system are mounted on the unit body. The rust removing device is composed of a motor, a flexible shaft, and a rust removing head which are sequentially connected. The rust removing head comprises a head main body, a sponge sleeve and a rust removing sheet. The head body is sleeved with the sponge sleeve, the rust removing sheet is mounted at the head portion of the head main body, and the guide device is composed of a hydraulic cylinder, a spiral elevator and a clamping claw assembly which are sequentially connected. The magnetic conductive pipe is fixed to the clamping claw, the rust removing sheet extends into the magnetic conductive pipe in the machining process, and the sponge sleeve is firmly attached to the inner wall of the magnetic conductive pipe. The control system is connected with the rust removing device and the guide device through electric circuits and controls the rust removing device and the guide device. The rust removing and polishing device can effectively treat metallic pipes for which rust cannot be removed through a magnetic grinding method, can finish the inner walls of various pipes and blind holes efficiently and is low in cost, wide in application range and convenient to mount and adjust.

Description

technical field

[0001] The invention relates to the technical field of derusting and polishing the inner walls of various tubes, in particular to a device for derusting and polishing the inner walls of magnetic tubes. Background technique

[0002] Pipe and hole workpieces are widely used in daily production. These workpieces will produce stains, rust, etc. during use, which will affect the use of such workpieces. Using percussion and chemical methods to derust the workpiece will cause damage, and the efficiency is low, and it will also pollute the environment. For bent pipe workpieces, it is difficult to remove the rust on the inner wall with traditional rust removal and polishing methods. Therefore, the rust removal and polishing of the inner walls of various pipes and holes has always been a difficult problem in finishing.

Embodiment Construction

[0028] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0029] Such as Figure 1-3 As shown, a device for derusting and polishing the inner wall of a magnetic tube includes a body 42 , a derusting device 40 installed on the body 42 , a guide device 41 , and a control system 43 .

[0030] The derusting device 40 is composed of a motor 17, a flexible shaft 13, and a derusting head 44 connected in sequence. Such as Figure 4 As shown, the derusting head 44 includes a head main body 35 , a sponge cover 39 , and a derusting sheet 37 . Rust removal sheet 37 is enclosed within head main body 35 heads, and sponge cover 39 is enclosed within head main body 35 outsides, and the outer surface of head main body 35 is covered with a circle groove, and then prevents sponge cover 39 from coming off, and sponge cover 39 makes rust removal sheet 37 can be tightly attached to the inner wall of the magnetic conduction...
