[0002] Laser cutting has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. It has gradually improved or replaced traditional metal cutting equipment.

[0003] At present, common laser cutting equipment such as laser tube cutting machines are generally used for cutting tubular materials or plate materials. During the cutting process, the tube rotates or moves while the laser cutting head is fixed in position, thereby cutting out a specific pattern or shape, which can meet the cutting processing needs of most steel materials.

[0004] In some specific industries, H-shaped steel needs to be cut and processed into a specific shape to achieve a tight connection between two components. Due to the structure of H-shaped steel, it is difficult to cut it with general laser cutting equipment. Utility Model Content

[0005] Based on the above description, the utility model provides an RTCP mechanism of a profile CNC cutting machine to solve the problem that it is difficult for general laser cutting equipment to cut H-shaped steel.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] The present application provides an RTCP mechanism of a profile CNC cutting machine, and the technical solution adopted is as follows:

[0008] An RTCP mechanism of a profile CNC cutting machine, comprising:

[0009] Support seat;

[0010] A mounting column connected to the support base with a vertical axis, wherein the mounting column can move relative to the support base in a vertical direction;

[0011] A first driving mechanism, which is connected to the mounting column and the support seat, and is used to drive the mounting column to move in a vertical direction;

[0012] A rotating shaft connected to the mounting post with a vertical axis, the rotating shaft being rotatably connected to the mounting post around its axis;

[0013] A second driving mechanism, which is connected to the rotating shaft and the mounting column and is used to drive the rotating shaft to rotate;

[0014] The laser cutting head is connected to the rotating shaft through a third driving mechanism, and the third driving mechanism is used to drive the laser cutting head to rotate around a horizontal rotating shaft, and the axis of the laser cutting head is perpendicular to its rotating shaft.

[0015] On the basis of the above technical solution, the present invention can also be improved as follows.

[0016] Preferably, the mounting post is hollow, and the rotating shaft is disposed in the mounting post and is rotatably connected to the mounting post.

[0017] Preferably, the second driving mechanism comprises:

[0018] A driven gear, whose coaxial ring is arranged outside the rotating shaft and fixed to the rotating shaft;

[0019] A driving gear, the axis of which is vertical and rotatably connected to the mounting column, the driving gear meshing with the driven gear;

[0020] A second motor is connected to the mounting column and is used to drive the driving gear to rotate.

[0021] Preferably, the diameter of the driving gear is smaller than the diameter of the driven gear.

[0022] Preferably, a vertical guide rail is provided on the mounting column, a sliding block adapted to the guide rail is fixed on the support seat, and the guide rail is assembled on the sliding block.

[0028] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0029] 1. The present application enables the laser cutting head to move vertically by setting the mounting column to be vertically movable. The laser cutting head can rotate around the vertical rotation axis and the horizontal rotation axis by setting the rotating shaft and the third driving mechanism. The vertical movement of the laser cutting head can adjust the distance from the steel to be cut. The rotation of the laser cutting head around the vertical rotation axis and the horizontal rotation axis can adjust the relative angle and position with the steel to be cut. According to the profile of the H-shaped steel, the laser cutting head can be kept perpendicular to the cutting surface for cutting operation, so that the cutting operation can be carried out smoothly, and at the same time, the cutting surface can be prevented from being inclined and producing sharp edges, ensuring that the cutting surface meets the requirements;

[0030] 2. The present application drives the rotating shaft to rotate through the cooperation of the second motor, the driving gear and the driven gear, thereby controlling the laser cutting head to rotate around the vertical rotating shaft. The driving gear and the driven gear cooperate to reduce the power of the motor, so as to realize the precise control of the rotation angle of the laser cutting head, and the equipment cost is low.
