Abstract
The utility model discloses an elbow pipe grinding tool which comprises a grinding head and a flexible shaft, wherein one end of the flexible shaft is connected with the grinding head, and the other end of the flexible shaft is connected with an actuating device. By using the flexible shaft as a connecting shaft to connect the actuating device with the grinding head, the elbow pipe grinding tool has the advantages of being simple in structure, convenient to manufacture, capable of enabling the grinding head to be suitable for grinding of the inner wall of an elbow pipe, enabling the inner wall to be smooth and clean and improving grinding efficiency and quality. In addition, due to the fact that a hose pipe is connected with the outer surface of the flexible shaft in a sleeved mode, in the process of high speed rotation, the flexible shaft is prevented from producing high temperature or rubbing the inner wall of the elbow pipe. By installing a gasket at the front end of the hose pipe, the flexible shaft is prevented from driving the hose pipe when rotating and displacement of the hose pipe is limited.
Description
Technical field
The utility model relates to the grinding machine field, relates in particular to a kind of bend pipe milling tools that is connected with flexible axle.
Background technology
At present, a kind of metallic conduit in food and medical industry use requires inwall clean, smooth, but this pipeline is generally nonlinear type (bend pipe) or internal diameter is less, long structure again, and existing milling tools can not satisfy the requirement of this pipeline of polishing.
The utility model content
Defective in view of above-mentioned prior art existence, the purpose of this utility model is to propose a kind of bend pipe milling tools that is connected with flexible axle, utilize flexible axle flexible and can connecting drive device and the character of grinding head, solve nonlinear type (bend pipe) or internal diameter less, the long inner-walls of duct of structure polishing problem makes it reach inner wall smooth, clean requirement.
The purpose of this utility model will be achieved by the following technical programs:
A kind of bend pipe milling tools comprises a grinding head and a flexible axle, and an end of described flexible axle is connected with described grinding head, and the other end is connected with a drive unit, realizes polishing.
Preferably, above-mentioned bend pipe milling tools, wherein: being shaped as of described grinding head is cylindrical, any in taper or the ellipse.
Preferably, above-mentioned bend pipe milling tools, wherein: described flexible axle comprises at least 2 layers steel wire winding layer, every layer of steel wire winding layer is entwined side by side by 4～12 steel wires.
Preferably, above-mentioned bend pipe milling tools, wherein: described steel wire is any of flat wire or round steel wire.
Preferably, above-mentioned bend pipe milling tools, wherein: be connected by an adapter sleeve between described flexible axle and the described grinding head.
Preferably, above-mentioned bend pipe milling tools, wherein: described adapter sleeve is riveted with described flexible axle and grinding head respectively.
Preferably, above-mentioned bend pipe milling tools, wherein: the outer surface of described flexible axle is socketed with a flexible pipe, prevents that flexible axle from producing high temperature or friction inner-walls of duct in the process of high speed rotating.
Preferably, above-mentioned bend pipe milling tools, wherein: described flexible pipe is provided with a pad for the displacement of restriction flexible pipe near an end of grinding head.
Outstanding effect of the present utility model is: bend pipe milling tools use flexible axle of the present utility model is done connecting axle drive unit is connected with grinding head, simple in structure, easy to make, make grinding head be applicable to the polishing of elbow internal wall, make inner wall smooth, clean, improve grinding efficiency and quality.In addition, the flexible axle outer surface is socketed with flexible pipe, prevents that flexible axle from producing high temperature or friction elbow internal wall in the high speed rotating process; At the flexible pipe front end pad is installed, is driven flexible pipe, the displacement of restriction flexible pipe when preventing that flexible axle from rotating.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
