[0002] In the field of intelligent manufacturing equipment, shaft parts are core transmission components, and the processing quality of their sealing surfaces directly determines the operating stability, sealing and service life of the equipment. The sealing surface is the interface between shaft parts and bearings, end covers and other components, and must meet high-precision geometric tolerances and excellent wear resistance to prevent oil leakage, dust intrusion or excessive wear of the mating surface during operation, thereby avoiding problems such as reduced transmission efficiency and equipment failure. The sealing surface grinding of shaft parts is generally carried out by machine tools, and the grinding components on the machine tools are used to grind the end faces, step surfaces and shaft surfaces of shaft parts. The grinding parts of existing machine tools usually have the following problems: 1. Due to the different rigidities of different shaft parts, and even the different rigidities of different parts of the same shaft part, in order to achieve better grinding results, it is necessary to frequently replace different grinding wheels. Even if some existing machine tools have a quick-change structure system, frequent replacement of grinding wheels will also affect the grinding efficiency and there will be positioning errors caused by wheel replacement; 2. Since existing machine tools are usually equipped with a single grinding wheel, the end face and step surface of shaft parts need to be ground separately, so secondary clamping is usually required, which will lead to the problem of accumulated clamping errors; Therefore, there is a need for an intelligent grinding device for the sealing surface of a wear-resistant composite machine tool shaft part to solve the problems raised in the above background.

The outer side of the connecting sleeve 318 is rotatably sleeved with a sleeve shell 319, and one end of the sleeve shell 319 is fixedly connected to the electric telescopic rod 320.

[0023] The axis-changing screw structure 305 includes an axis-changing screw body 321, a sliding rod and sleeve structure 322 and a second drive motor 324. The movable seat of the axis-changing screw body 321 is arranged in the movable wheel 501 at the top, and is rotatably connected with the movable wheel 501.

[0024] One side of the movable seat in the horizontal screw structure 309 is rotatably inserted with a limiting wheel 325, and one end of the limiting wheel 325 is inserted into the horizontal sliding groove 307 on the first movable plate 301 and abuts against the outer side of the transmission belt in the second gear transmission belt structure 401.

[0025] The multi-diameter transmission shaft 502 is formed by a plurality of circular shafts of different diameters being fixedly connected, and a bevel buffer portion 504 is provided at the connection between the plurality of circular shafts.

[0026] In this embodiment, since the limiting wheel 325 is arranged on the movable seat in the horizontal screw structure 309, and the movable seat in the horizontal screw structure 309 is connected to the transmission wheel at the other top end of the second gear transmission belt structure 401 through the connecting rod 312, the position of the limiting wheel 325 and the corresponding transmission wheel is relatively fixed, and the transmission belt of the second gear transmission belt structure 401 is limited, thereby ensuring the connection area between the transmission belt of the second gear transmission belt structure 401 and the corresponding transmission wheel, thereby ensuring the transmission effect, so that the transmission effect will not be weakened due to the movement of the transmission wheel; An inclined buffer portion 504 is provided at the connection of the circular shaft, so that when the sanding belt body 503 moves along the multi-diameter transmission shaft 502, a smooth transition can be achieved, thereby ensuring the moving effect.

[0027] The present invention can adjust the relative distances between the grinding surfaces of the movable grinding wheel structure 4, the grinding surfaces of the movable grinding belt structure 5, and the grinding surfaces of the fixed grinding wheel structure 2 by controlling the distance-adjusting screw structure 303 and the axis-changing screw structure 305. This allows at least two surfaces of shaft parts to be ground simultaneously when they are ground. This is equivalent to a position limit and requires one less adjustment of the grinding wheel position and angle than with conventional machine tools. Therefore, the grinding effect can be guaranteed and the shaft parts do not need to be clamped twice. And because the movable grinding wheel structure 4, the movable grinding belt structure 5 and the fixed grinding wheel structure 2 are on the same axis, the grinding angles between them can also be guaranteed, so that when the shaft parts are ground, the grinding angle of the step surface can be vertical, ensuring the grinding effect of the step surface.

[0028] Working principle of the present invention: When the present invention is used, the mounting base 1 drives the fixed grinding wheel body 204 to rotate by connecting to the first connecting shaft 201. At the same time, the rotation of the first connecting shaft 201 drives the first gear transmission belt structure 202 to move, and then drives the second gear transmission belt structure 401 to move through the first transmission shaft 205. The movement of the second gear transmission belt structure 401 drives the movable grinding wheel body 402 to rotate, and then drives the multi-diameter transmission shaft 502 to rotate through the connecting rod 312. The rotation of the multi-diameter transmission shaft 502 causes the grinding belt body 503 sleeved on the outside of the two movable wheels 501 and the multi-diameter transmission shaft 502 to move; When the movable grinding wheel structure 4 and the movable grinding belt structure 5 need to be adjusted according to the diameter of the shaft parts, the movable grinding wheel structure 4 is adjusted in the following manner: the first drive motor 314 is started, and the first drive motor 314 drives the screw portion of the vertical screw structure 310 to rotate, so that the moving seat of the vertical screw structure 310 drives the transmission wheel at the bottom end of the second gear transmission belt to move along the vertical slide groove 308 of the first movable plate 301, and at the same time, the screw portion of the vertical screw structure 310 rotates to drive the vertical bevel gear 315 to rotate synchronously, and then drives the gear connector 317, the connecting sleeve 318 and the screw connector 313 to rotate in sequence through the transverse bevel gear 316, so that the transverse screw structure 310 is rotated. The screw portion of 09 rotates along with the screw connector 313, so that the movable seat of the horizontal screw structure 309 drives the transmission wheel at the other top end of the second gear transmission belt structure 401 to move along the horizontal sliding groove 307 of the first movable plate 301 through the connecting rod 312. When it is necessary to increase the distance between the grinding surface of the movable grinding wheel structure 4 and the grinding surface of the fixed grinding wheel structure 2, the movable seat of the vertical screw structure 310 moves downward, and at the same time, the movable seat of the horizontal screw structure 309 moves inward. When it is necessary to reduce the distance between the grinding surface of the movable grinding wheel structure 4 and the grinding surface of the fixed grinding wheel structure 2, the movable seat of the vertical screw structure 310 moves upward, and at the same time, the movable seat of the horizontal screw structure 309 moves outward. The distance adjustment method of the movable sanding belt structure 5 is as follows: start the first drive motor 314, the first drive motor 314 drives the screw part of the vertical screw structure 310 to rotate, so that the movable seat of the vertical screw structure 310 drives the movable wheel 501 at the bottom end of the movable sanding belt structure 5 to move along the vertical slide groove 308 direction of the second movable plate 302 and the third movable plate 304 through the slide rod sliding sleeve structure 322, and at the same time, the screw part of the vertical screw structure 310 rotates to drive the vertical bevel gear 315 to rotate synchronously, and then drives the gear connector 317, the connecting sleeve 318 and the screw connector 313 to rotate in sequence through the transverse bevel gear 316, so that the transverse screw structure 30 The screw portion of 9 rotates along with the screw connector 313, so that the movable seat of the horizontal screw structure 309 drives the multi-diameter transmission shaft 502 to move along the horizontal sliding groove 307 of the second movable plate 302 and the third movable plate 304 through the connecting rod 312. When it is necessary to expand the distance between the grinding surface of the movable sand belt structure 5 and the grinding surface of the fixed grinding wheel structure 2, the movable seat of the vertical screw structure 310 moves downward, and at the same time, the movable seat of the horizontal screw structure 309 moves inward. When it is necessary to reduce the distance between the grinding surface of the movable sand belt structure 5 and the grinding surface of the fixed grinding wheel structure 2, the movable seat of the vertical screw structure 310 moves upward, and at the same time, the movable seat of the horizontal screw structure 309 moves outward. The shaft changing method of the movable sanding belt structure 5 is to start the electric telescopic rod 320, drive the connecting sleeve 318 to move toward the gear connecting head 317 through the sleeve shell 319, so that the connecting sleeve 318 is separated from the screw connecting head 313, and then start the first drive motor 314. The first drive motor 314 drives the screw part of the vertical screw structure 310 to rotate, so that the moving seat of the vertical screw structure 310 drives the movable wheel 501 at the bottom end of the movable sanding belt structure 5 to move along the vertical slide groove 308 direction of the second movable plate 302 and the third movable plate 304 through the slide rod sliding sleeve structure 322. At the same time, the second drive motor 324 is started to drive the screw part of the shaft changing screw body 321 to rotate, so that the moving seat of the shaft changing screw body 321 drives the movable wheel 501 at the top end of the movable sanding belt structure 5 The wheel 501 moves along the direction of the screw part of the axis-changing screw body 321. At the same time, when the movable seat of the axis-changing screw body 321 moves, the sliding sleeve part of the sliding rod sliding sleeve structure 322 is driven to move synchronously along the direction of the sliding rod part through the linkage plate 323. Therefore, the two movable wheels 501 move synchronously in the same direction, thereby driving the other end of the sanding belt body 503 to move along the direction of the multi-diameter transmission shaft 502. When it needs to move to the large diameter direction of the multi-diameter transmission shaft 502, the sliding rod sliding sleeve structure 322 drives the movable wheel 501 at the bottom end of the movable sanding belt structure 5 to move upward. When it needs to move to the small diameter direction of the multi-diameter transmission shaft 502, the sliding rod sliding sleeve structure 322 drives the movable wheel 501 at the bottom end of the movable sanding belt structure 5 to move downward, so that the sanding belt body 503 is always taut for subsequent use.
