DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 As shown, an axis position monitoring device for a five-axis machining center includes a position sensor 1, a fixing mechanism 2 is installed on the position sensor 1, and the fixing mechanism 2 includes a first clamping block 201, one end of the position sensor 1 is fixedly connected to the first clamping block 201, and one end of the position sensor 1 is slidably connected to a compression spring 203 and a gasket 204, one end of the compression spring 203 is connected to the side wall of the first clamping block 201, and the other end of the compression spring 203 is connected to the side wall of the gasket 204, and the other end of the position sensor 1 is threadedly connected to the second clamping block 202, the second clamping block 202 and the first clamping block 201 are both "concave" shaped structures, and a protective mechanism 3 is installed on the first clamping block 201.

[0024] As a technical optimization solution of the present invention, rubber pads 205 are respectively installed on the opposite sides of the second card block 202 and the gasket 204. One side of the rubber pad 205 is a tooth-shaped structure. Through the installation of the rubber pad 205, the first card block 201 and the second card block 202 are tightly clamped to the device casing and play an anti-slip role.

[0025] As a technical optimization solution of the present invention, card slots 206 are provided at both ends of the second card block 202. The card slots 206 are "U"-shaped structures. The opening of the card slots 206 facilitates winding and locking of multiple data lines, thereby preventing the data lines from breaking at the connection with the position sensor 1.

[0026] As a technical optimization solution of the present invention, multiple groups of symmetrically distributed rubber blocks 207 are provided inside the two card slots 206. The multiple groups of symmetrically distributed rubber blocks 207 are respectively connected to the second card block 202. The rubber blocks 207 have a triangular structure. The installation of multiple groups of rubber blocks 207 facilitates the resistance of the data cables engaged in the card slots 206, thereby preventing the data cables from falling off and protecting the data cables.

[0027] As a technical optimization solution of the present invention, one end of multiple groups of rubber blocks 207 respectively extends to the inner side of the second card block 202, and an extrusion spring 208 is connected between one end of multiple groups of rubber blocks 207 and the interior of the second card block 202. The rubber blocks 207 are slidably connected to the interior of the second card block 202 through the extrusion spring 208. The installation of the extrusion spring 208 makes the rubber blocks 207 elastic, which is conducive to tightly clamping the data cable, preventing damage to the data cable caused by excessive squeezing, and preventing the data cable from loosening.

[0028] As a technical optimization solution of the present invention, the protective mechanism 3 includes a mounting frame 301, and the mounting frame 301 is installed on the first clamping block. The mounting frame 301 is a frame-type structure. The installation of the mounting frame 301 is beneficial to protecting the outer side of one end of the position sensor 1.

[0029] As a technical optimization solution of the present invention, slide grooves 305 are provided on both sides of the mounting frame 301, and a slide plate 302 is provided on the mounting frame 301. The slide plate 302 is slidably connected to the mounting frame 301 through the slide grooves 305. The installation of the slide plate 302 is beneficial to shielding and protecting one end of the position sensor 1, and the sliding of the slide plate 302 facilitates the cleaning and maintenance of the position sensor 1.

[0030] As a technical optimization solution of the present invention, a reset spring 307 is connected between the bottom side of one end of the skateboard 302 and the mounting frame 301, and a push block 303 is installed on one side of the skateboard 302. The installation of the reset spring 307 facilitates the pulling and resetting of the skateboard 302, so that the skateboard 302 maintains shielding and protecting the position sensor 1. The drive control of the skateboard 302 is achieved by pushing the push block 303 through an external limit block.

[0031] As a technical optimization solution of the present invention, the push block 303 is a trapezoidal structure, and a protective pad 304 is installed on the side wall of one end of the push block 303, which is conducive to making the push block 303 less likely to be damaged by friction. The installation of the protective pad 304 can prevent friction and wear.

[0032] As a technical optimization solution of the present invention, a brush 306 is installed at the center of the other side of the skateboard 302. The brush 306 has a trapezoidal structure. One end of the brush 306 contacts the position sensor 1. The installation of the brush 306 facilitates the protection of the position sensor 1 from contact. The sliding of the skateboard 302 causes the brush 306 to scrape the position sensor 1, thereby scraping off the dust on the position sensor 1.

[0033] When the utility model is used, a hole is first punched on the device housing, and then the position sensor 1 is inserted into the hole and installed with the housing, and after the gasket 204 on the first clamping block 201 contacts the side wall of the device housing, the second clamping block 202 is threadedly connected to the position sensor 1, so that the second clamping block 202 contacts the other side of the device housing, thereby achieving a stable installation of the position sensor 1 on the housing, and under the interference of the compression spring 203, the gasket 204 contacts the housing tightly, and the rotation of the second clamping block 202 is achieved under the action of the thread. The extended length of the position sensor 1 is controlled to facilitate the cooperation with the limit block on the shaft to monitor the position. A card slot 206 and a rubber block 207 are provided at both ends of the second card block 202, which is beneficial for the protection of the data line engagement. When the machine tool shaft moves to a certain position, the limit block on the shaft contacts the push block 303, so that the push block 303 drives the slide plate 302 to slide, and the brush 306 on the slide plate 302 cleans the position sensor 1. At the same time, after the slide plate 302 is opened, the limit block has no contact with the position sensor 1, and then position monitoring and signal transmission are carried out, so that the computer can recognize the shaft position.
