Description

Technical Field

[0001] This utility model relates to the field of cutting machine tool technology, and in particular to a non-metallic cutting machine tool. Background Technology

[0002] Traditional non-metallic cutting machine tools require zeroing before cutting to determine the starting position of the cutting tool, thus more accurately controlling various parameters during the machining process and ensuring the machining accuracy of the workpiece. However, during the cutting process, the position of the cutting tool can only be estimated based on preset parameter values, resulting in limited accuracy and difficulty in meeting the requirements of high-precision cutting. Furthermore, installation and debugging are inconvenient, affecting cutting efficiency and quality. Utility Model Content

[0003] The purpose of this invention is to provide a non-metallic cutting machine tool, in which magnetic pole positioning structures are provided in both the longitudinal and transverse guide rails, so that the position of the cutting tool can be accurately positioned at all times when the two guide rails control the movement of the cutting tool, thereby solving the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a non-metallic cutting machine tool, including a cutting table and a magnetic pole positioning structure. The magnetic pole positioning mechanism includes a positioning bar, a moving plate and a positioning cylinder. The side of the moving plate away from the positioning bar is provided with an radio frequency laser cutter for cutting non-metallic materials. The side of the moving plate facing the positioning bar is fixedly connected with a positioning cylinder for high-precision positioning and cutting. The moving plate moves along the positioning bar.

[0006] The positioning cylinder has a positioning column inside, and the side of the positioning column facing the positioning hole has an inner hole, and a magnetic pole positioning coil is embedded in the inner hole to perform induction positioning based on the magnetic induction of the magnetic column.

[0007] A miniature electric actuator is fixedly connected between the positioning column and the inner wall of the positioning cylinder. The miniature electric actuator pushes the positioning column to move and engages the front end of the positioning column into the positioning hole for precise positioning of the moving plate.

[0008] Preferably, the positioning strip has mounting holes on its side, and the mounting holes and positioning holes are located on both sides of the positioning strip, respectively. The mounting holes and positioning holes are interconnected and used for positioning and installing the magnet post and the connector.

[0009] Preferably, both the mounting hole and the connector have a structure with a larger diameter at one end and a smaller diameter at the other end. When the connector is inserted into the mounting hole, a spring between the connector and the inner wall of the mounting hole is used to limit the connection between the connector and the magnet post.

[0010] Preferably, the corner of the positioning post facing the positioning strip is an inclined surface, the opening diameter of the positioning cylinder is smaller than the diameter of the positioning post, and the opening of the positioning cylinder limits the positioning post when the positioning post moves.

[0011] Preferably, a conductive sheet is fixedly connected to the side end face of the positioning post, and a conductive head is fixedly connected to the inner side wall of the positioning cylinder.

[0012] Preferably, the cutting table is provided with longitudinal guide rails on both sides, and a U-shaped transverse guide rail is provided between the two longitudinal guide rails.

[0014] The beneficial effects of this utility model are as follows: magnetic pole positioning structures are set between the radio frequency laser cutter and the horizontal guide rail, and between the horizontal guide rail and the vertical guide rail. During the movement of the moving plate, the magnetic pole positioning coil positions the magnetic pole of the magnetic column, thereby accurately knowing the position of the moving plate.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] See Figures 1-5 The present invention provides a non-metallic cutting machine tool, including a cutting table 1 and a magnetic pole positioning structure. The magnetic pole positioning mechanism includes a positioning bar 6, a moving plate 4 and a positioning cylinder 10. The side of the moving plate 4 away from the positioning bar 6 is provided with an radio frequency laser cutter 5 for cutting non-metallic materials. The radio frequency laser cutter 5 is a radio frequency CO2 laser cutter. The side of the moving plate 4 facing the positioning bar 6 is fixedly connected to the positioning cylinder 10 for high-precision positioning and cutting. The moving plate 4 moves along the positioning bar 6. The fixed connection method can also be welding, riveting, screwing or gluing.

[0023] The positioning strip 6 has a positioning hole 61 on the side facing the moving plate 4. A magnet post 13 for magnetic pole positioning is placed inside the positioning hole 61, and a connector 8 is threaded to the side end of the magnet post 13. To ensure stable installation, the positioning strip 6 has a mounting hole 7 on its side. The mounting hole 7 and the positioning hole 61 are located on opposite sides of the positioning strip 6 and are interconnected, used for positioning and installing the magnet post 13 and the connector 8. Both the mounting hole 7 and the connector 8 have a structure with one end larger than the other. When the connector 8 is inserted into the mounting hole 7, a spring 9 between the connector 8 and the inner wall of the mounting hole 7 limits the movement of the connector 8 and the magnet post 13. When installing the magnet post 13, first place the spring into the mounting hole, then insert the connector 8 along the inner hole of the spring 9 until the connector 8 is positioned and connected to the magnet post 13. When the magnetism of the magnet post 13 is damaged, the magnet post can be replaced. This design simplifies the installation process, reduces the installation difficulty, reduces machine tool downtime, and improves production efficiency. When the moving plate moves to the magnet post, the magnet post will move towards the magnetic pole positioning coil, and the magnetic pole positioning coil will sense more clearly. When the moving plate moves away from the magnet post 13, the spring 9 will reset the magnet post 13, weakening the induction of the magnetic pole positioning coil 14 on the magnet post 13 and reducing the interference of magnetic poles between two adjacent magnet posts 13.

[0024] Both sides of the cutting table 1 are provided with longitudinal guide rails 2, and a U-shaped transverse guide rail 3 is provided between the two longitudinal guide rails 2. The structures of the transverse guide rail 3 and the longitudinal guide rail 2 are mature guide rail structures of existing machine tools. This application document does not show the connection structure and movement structure of the two in detail, which does not affect the integrity of this solution. A magnetic pole positioning structure is also provided at the connection between the transverse guide rail 3 and the longitudinal guide rail 2 for magnetic pole positioning between the longitudinal guide rail 2 and the transverse guide rail 3. The positioning cylinder 10 has a positioning post 11 inside. The side of the positioning post 11 facing the positioning hole 61 has an inner hole, and a magnetic pole positioning coil 14 is embedded in the inner hole for induction positioning of the magnetic pole 13. When the cutting machine tool is working, the transverse guide rail 3 moves along the longitudinal guide rail 2, the radio frequency laser cutter 5 moves along the transverse guide rail 3, and the moving plate 4 drives the positioning cylinder 10 to pass through the positioning hole 61 in sequence. The magnetic pole positioning coil 14 induces the magnetic pole of the magnetic pole 13.

[0025] A miniature electric actuator 12 is fixedly connected between the positioning post 11 and the inner wall of the positioning cylinder 10. The miniature electric actuator 12 pushes the positioning post 11 to move and engages the front end of the positioning post 11 into the positioning hole 61 for precise positioning of the moving plate 4. The corner of the positioning post 11 facing the positioning strip 6 is inclined, and the opening diameter of the positioning cylinder 10 is smaller than the diameter of the positioning post 11. When the positioning post 11 moves, the opening of the positioning cylinder 10 limits the positioning post 11. The miniature electric actuator 12 is connected to the control terminal. Because the position of each positioning hole 61 is fixed, when the miniature electric actuator 12 drives the positioning post 11 to move, the top end of the positioning post 11 engages into the positioning hole 61. This allows for precise positioning of the radio frequency laser cutter 5.

[0026] A conductive sheet 15 is fixedly connected to the side end face of the positioning post 11, and a conductive head 16 is fixedly connected to the inner wall of the positioning cylinder 10. The conductive sheet 15 and the conductive head 16 are respectively connected to the two poles of the power supply. When the conductive sheet 15 and the conductive head 16 are in contact with each other, the top end of the positioning post 11 is in contact with the magnetic post 13, which is used to reposition the position of the moving plate 4. When the top end of the positioning post 11 is engaged in the positioning hole 61, the conductive sheet 15 and the conductive head 16 are in contact with each other, thereby connecting the circuit. The control terminal repositions the RF laser cutter 5 according to the marking of the positioning hole 61, ensuring precise control of the position of the RF laser cutter 5 during processing.

[0027] Both the longitudinal guide rail 2 and the transverse guide rail 3 have drive motors on their sides. The cutting table 1 has a control terminal on its side, which has a built-in programmable logic controller. The magnetic pole positioning coil 14 has a built-in central processing module. It uses the singular value truncation (SDM) algorithm to perform magnetic field control, signal calculation, and coordinate output of the positioning hole 61. The core logic of SDM is to modify the SDM using singular value characteristics. By calculating the pseudo-inverse of the magnetic field strength difference between the sampling point, i.e., the position of the positioning hole 61, and the current solution, and discarding the components corresponding to smaller singular values, it learns the generalized gradient along the direction with the largest magnetic field strength difference. The position of the RF laser cutter 5 is continuously repositioned through the positioning hole 61.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
