[0029] The detailed connection means is a technology known in the art. Figs. 1-3 The height detection part

[0030] Components: the detection head 6 is fixed to the lower end of the sliding rod 13 through the cover-shaped nut and the hexagonal nut 20, and the height thereof can be adjusted by rotating the cover-shaped nut 19. The detection head 6 is composed of two parts, and the extension length thereof is adjusted by a fixing screw. The upper end of the sliding rod 13 is connected to the spring groove moving seat 14, and a locking screw is used for fixing. The spring groove moving seat 14 is fixed to the sliding block 18, and moves up and down by means of the slide rail 17.

[0031] A compression spring 16 is installed on the cantilever of the spring groove, and is installed between the fixed ring directly above and the compression spring 16. When the probe is subjected to force, the compression spring 16 will be elastically deformed. When the probe is no longer subjected to force, the spring will restore the deformation to reset the probe.

[0032] The fixed ring, the transition ring, the transition cover 8 and the height detection shell 4 are sequentially connected, the displacement sensor 5 is installed on the transition cover 8, the bottom of the probe is in contact with the center groove of the spring groove in a relaxed state, and the signal compression transmission is performed with the probe rising.

[0033] The bushing is fixed to the threaded top of the lower end of the sliding rod 13 through the hexagonal nut 20, and the tower-shaped protective sleeve 21 wraps the bushing and the annular base at the lower end of the shell to prevent splashing from polluting the internal structure during work.

[0034] The sensor fixing shell, the sensor fixing plate 2, the shell fixing plate 2 and the shell are sequentially fixed and installed by screws. Four groups of contact sensors 7 are uniformly distributed on the sensor fixing plate 2.

[0035] The transition cover 8 of the height detection part is butted in the corresponding position with the sensor fixing shell of the impact detection part, ensuring that the contact sensor 7 is in contact with the surface of the transition cover 8; the height detection part and the impact detection part are connected through the extension spring 10, and the spring support 11 is installed to adjust the height of the upper cover, so as to tightly contact the two; the transition cover 8 of the height detection part is installed with a plurality of positioning pins, and the sensor fixing shell in the corresponding position is provided with a hole position, so as to prevent the rotation of the height detection part; the support 1 is installed to the anti-collision part shell through the fixing plate 2, and is connected with the five-axis tool head.

[0036] When the detection head 6 contacts the material surface, the force is compressed upward, driving the compression spring 16 to elastically deform, and the spring groove moving seat 14 is displaced upward, pushing the displacement sensor 5 to generate a height signal; when the force is removed, the compression spring 16 restores the deformation, so that the probe is reset.

[0037] The height detection part and the impact detection part are connected through four groups of extension springs 10. If the detection head 6 collides with the material, the height detection part will be tilted in the opposite direction, causing the transition cover 8 to separate from the contact sensor 7, thereby generating a collision signal; when the detection head 6 separates from the material, the extension spring 10 restores it to the initial position by pulling force, and the collision signal is removed.

[0038] The device is directly connected to the AC five-axis tool head through the support 1, and the sensor wire enters the inside of the tool head to avoid interference. The whole device rotates with the C shaft, and remains relatively static with the C shaft of the AC five-axis tool head, thereby reducing the detection error.

[0039] Through the above design and working principle, the device effectively improves the height measurement and anti-collision ability of water jet cutting, and provides a more reliable solution for practical application.

Although the present application has been disclosed as above with the preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the technical solution of the present application, and any equivalent embodiments with equivalent changes are equivalent to the above embodiments.
