Abstract

The utility model relates to a slot groove machining device for a pipe. The utility model comprises a base station, a main shaft and an annular concave groove arranged at one end part of the main shaft. The base station is connected with a wheel frame of a pressure groove in a rotational mode. The wheel frame of the pressure groove is provided with a wheel shaft of the pressure groove in a rotational mode. A radial annular convex pressure groove wheel is arranged on the wheel shaft of the pressure groove. The upper part of the base station is fixedly connected with a cover of a lifting frame. A lifting screw rod is connected with the cover of the lifting frame through a screw thread. The lower end part of the lifting screw rod is abutted on the wheel frame of the pressure groove. The upper end part of the lifting screw rod is connected with a lifting hand wheel. The wheel frame of the pressure groove is used as a lever. The lifting hand wheel can be easily rotated. The operation is simple and convenient.

Description

Pipe groove processing machine

Technical field

The utility model is about pipe groove processing machine, this function process simply running water pipe for example etc. the end be used for the annular ditch groove that joint connects.

Background technology

Will use joint in the pipelaying work of running water pipe etc., joint has two kinds of the nipple of band gas thread and bump joints usually.

Nipple normally directly cuts the screw thread of band tapering on the excircle of pipe, pipe joint by box thread is arranged and same pipe link together, and gas thread generally is to use movably small-sized lathe to carry out machining.

It is bigger that bump joint normally is used for pipe diameter, and the fluid pressure of carrying is than under the condition with higher.The flange of burn-oning in advance on pipe connects together with same pipe by welding, rivet or bolt then.

Above-mentioned preceding a kind of nipple when connecting or dismantle, all must make the pipe rotation, at the bottom of pipelaying work trouble and the efficient, when doing the pipe repairing or changing, pipe need be taken off simultaneously, and can not be in original then carrying out under the state, its inconvenience is apparent.

The lathe that screw cutting is used is heavy, carrying inconvenience, and screw chasing operation complexity.

A kind of various bump joints in back need in advance pipe and flange are welded together, therefore, and for some operation field with must determine that the pipelaying work of pipeline length is not suitable for.

Summary of the invention

The purpose of this utility model just provides a kind of like this groove processing machine simple in structure, and in order to make pipe connection and dismounting operation easy, the place that can need in the end of pipe with this machine forms the annular ditch groove that adapts with relevant union piece.

The technical solution of the utility model is: a kind of pipe groove processing machine, comprise base station, be arranged on the main shaft on the base station rotationally, be arranged at the annular recess of an end of main shaft, be connected with the indent wheel carrier rotationally by the wheel carrier rotating shaft on the described base station, be provided with the indent wheel shaft rotationally on the described indent wheel carrier, this indent wheel shaft is provided with the indent wheel of radial ringed protrusion, be fixedly connected with the crane lid on the described base station, a lifting screw is threaded with the crane lid, the bottom of this lifting screw is against on the indent wheel carrier, and the upper end of lifting screw is connected with the lifting handwheel.

Processed pipe is enclosed within on the main shaft, and when the swivel feeding lifting screw, the indent wheel carrier descends, and makes the annular projection position of indent wheel be pressed onto on the processed pipe.Under this state, make main axis rotation, and allow lifting screw do screwfeed slowly casually, this moment, indent wheel and main shaft all began rotation, meanwhile the indent wheel of ring-type protrusion promptly is pressed in the ring-type chase of main shaft, forms the ring-type chase on the periphery of processed pipe.

Like this, the pipe that has had a finished groove with have pipe with spline structure and just be easy to roll up press and be connected.That is, the end of two pipes is involutory mutually, have inwardly protruded union piece rolling up one on the periphery at its involutory position, the involutory pressure of rolling up of groove on its each lug boss and each pipe, volume is pressed and is finished soon that two pipes connect.

The utility model has the advantages that:

Therefore indent wheel carrier and base station are rotatably connected, and the indent wheel carrier plays the effect of lever, and it is comparatively laborsaving to rotate the lifting handwheel, operates easy and convenient.Compared with bump joint with former nipple, pipelaying work is more easy, and operating efficiency is higher.
