Description

Technical Field

[0001] The utility model relates to the technical field of cutting heads for pipe cutters, in particular to an angle-adjustable cutting head for pipe cutters. Background Art

[0002] The principle of the pipe cutting machine is that the air-oil pushes the mutual cooperation. The electrical system controls the movement direction of the air pressure system, pushing the oil circuit to make a straight line reciprocating motion. During the reciprocating motion, the signal detected from the drag plate limit is used as a basis to control and change the movement of the air and oil circuits, so as to achieve the expected cutting path.

[0003] The cutting parts of general pipe cutting machines can only move up and down and forward and backward, and cannot adapt to side cutting conditions, so their application range is narrow. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an adjustable angle cutting head for a pipe cutting machine, which has a simple structure and can adjust the changes of the X-axis, Z-axis and A-axis (rotation angle) of the cutting component through the cooperation of a linear motor, a lifting motor and a rotating motor, and has a wide range of applications.

[0005] In order to solve the above technical problems, the utility model provides an adjustable angle cutting head for a pipe cutting machine, comprising an X-axis base plate, an X-axis track and a linear motor are arranged on the X-axis base plate, a crossbeam is arranged at the output end of the linear motor, a Z-axis base plate is arranged on one side of the crossbeam, a Z-axis track and a lifting motor are arranged on the Z-axis base plate, a Z-axis slide is arranged on the Z-axis track, a rack is arranged on the Z-axis slide, and a gear matched with the rack is arranged at the output end of the lifting motor; a rotating motor is arranged on the Z-axis slide, a harmonic reducer is arranged at the output end of the rotating motor, a swing arm plate is arranged on the harmonic reducer, and a cutting assembly is arranged on the swing arm plate.

[0006] Furthermore, a wire trough fixing plate is provided on the swing arm plate, and an A-axis trough tube is provided on the wire trough fixing plate; including an A-axis hose, and hose clamps are provided at positions where both sides of the A-axis hose are connected to the crossbeam and the A-axis trough tube.

[0007] Furthermore, a hose support plate and a hose buffer plate are provided on the crossbeam at a position corresponding to the A-axis hose.

[0008] Furthermore, a wire trough hole is provided on one side of the crossbeam, and an XZ cable support plate is provided on the crossbeam at a position corresponding to the wire trough hole.

[0009] Furthermore, an X-axis dustproof plate is provided on a side of the beam away from the linear motor.

[0010] Furthermore, Z-axis dustproof plates are provided on both sides of the Z-axis base plate.

[0011] The beneficial effects of the utility model: when the device is used, the cutting assembly is adjusted as follows: the linear motor is started, and the linear motor drives the crossbeam to move forward and backward on the X-axis track, thereby driving the cutting assembly to move forward and backward to change the position of the X-axis; the lifting motor drives the gear to rotate, and the cooperation of the rack and the gear makes the Z-axis slide plate move up and down along the Z-axis track, thereby changing the Z-axis position of the cutting assembly; finally, the rotating motor is started to drive the rotary arm plate to rotate, thereby changing the A-axis position of the cutting assembly, and the adjustment range is wide.
