Abstract

The utility model discloses a steel tube beveling machine which comprises a frame. The frame is connected with a main shaft sleeve in a sliding manner; a main shaft is rotationally connected in the main shaft sleeve, and one end thereof is connected with a knife carrier, and the other end thereof is fixedly connected with a spline shaft; the spline shaft is dynamically connected with a power device mounted on the frame; the main shaft sleeve is driven to slide by a feeding mechanism; and a steel tube clamping device adjacent to the knife carrier is mounted on the frame. The steel tube beveling machine with the structure has the advantages of simple structure and low manufacturing cost and can conveniently realize the bevel processing to the end part of a steel tube.

Description

The steel pipe beveling machine

Technical field

The utility model relates to the equipment of cutting steel pipe port tube wall, is specifically related to a kind of steel pipe beveling machine.

Background technology

In the heat-exchanger rig that uses in the industry such as boiler and chemical industry, heat exchange element is made up of steel pipe mostly, and steel pipe mostly carries out fixedly connected in the mode of welding, in order to improve weld strength, and need be before the welding at the end of steel pipe finished edge.At present, also there is not a kind of steel pipe beveling machine simple in structure, that cost of manufacture is low to occur.

Summary of the invention

The technical problems to be solved in the utility model is at above-mentioned defective, provide a kind of can be at the machinery of steel tube end part finished edge.

For solving the problems of the technologies described above, the utility model provides a kind of steel pipe beveling machine of following structure, comprise frame, it is characterized in that slidely connecting collar bush on the frame, be rotatably connected to main shaft in the collar bush, an end of main shaft is connected with knife rest, the other end of main shaft is connected with splined shaft, splined shaft is connected with power set power on being contained in frame, and the slip of collar bush is driven by feed mechanism, and the steel pipe fixture that is provided with near knife rest is housed on the frame.

Described power set comprise and are rotatably connected on the frame and the spline housing that is connected with splined shaft power, are installed with driven gear on the spline housing, driven gear and the driving gear engagement that is contained on the motor.

Described feed mechanism comprises the handwheel that is rotatably connected on the frame, and handwheel is by rack and pinion drive mechanism drive shaft cover.

Described clamping device comprises the door frame that is contained on the frame, fixture block is housed down on the door frame and slidely connects fixture block, and last fixture block is driven by the leading screw that is screwed onto on the door frame.

The utility model is by being connected collar bush on the frame, being rotatably connected on main shaft in the collar bush, being connected knife rest and the splined shaft on the main shaft and being connected clamping device on the frame and the combination of several limited parts such as power set, just can realize goal of the invention, therefore, the utlity model has advantage simple in structure, that cost of manufacture is low, realization that can be easy to operate is to the groove processing of steel tube end part.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
