Where specific technical or conditions are not described, the techniques or conditions described in the literature or according to the product manual are used.

[0033] Referring to Figures 1-3 A ceramic bond grinding wheel, comprising a grinding plate 6 and a mounting plate 7, the mounting plate 7 is provided with a mounting hole in the middle, the structure section of the grinding plate 6 and the mounting plate 7 is an outwardly expanded U-shaped structure, the ceramic bond grinding wheel is machined by a ceramic bond grinding wheel machining machine, comprising a bottom plate 1 and a fixed plate 2 fixed on the top of the bottom plate 1 at the front and rear ends, a back plate 3 is fixed on the rear side of the front end of the fixed plate 2, a fixed machining part 4 is installed on the rear side of the front end of the fixed plate 2 above the back plate 3, and a rotary clamping part 5 is installed on the front side of the rear end of the fixed plate 2. The ceramic bond grinding wheel is clamped and rotated by the rotary clamping part 5 and the back plate 3, and the outer ring surface and the mounting hole are trimmed by the fixed machining part 4. When the ceramic bond grinding wheel is trimmed, the outer ring surface of the ceramic bond grinding wheel is fully trimmed by scraping, brushing and edging. The purpose of scraping is to remove surface impurities on the outer ring surface of the ceramic bond grinding wheel, so as to avoid the influence of impurities attached to the outer ring surface of the ceramic bond grinding wheel on the use of the grinding wheel. Brushing is to further remove impurities attached to the outer ring surface of the ceramic bond grinding wheel. Edging is to effectively process irregular protrusions on the outer ring surface of the ceramic bond grinding wheel, so as to avoid the influence of irregular protrusions on the outer ring surface of the ceramic bond grinding wheel on the polishing effect. Specifically, first, the ceramic bond grinding wheel is placed between the back plate 3 and the rotary clamping part 5, then the rotary clamping part 5 is controlled to press against the ceramic bond grinding wheel and cooperate with the back plate 3 to complete the positioning of the ceramic bond grinding wheel, then the fixed machining part 4 is controlled to move backward and reach a position suitable for machining the upper part of the fixed machining part 4, the position of the upper part of the fixed machining part 4 is adjusted, then the rotary clamping part 5 is controlled to rotate to drive the ceramic bond grinding wheel to rotate, and the movement of the upper part of the fixed machining part 4 is controlled to complete the trimming of the ceramic bond grinding wheel.

[0034] Referring to Figure 8 and Figure 9The rotating clamping part 5 comprises a rotating motor 51 mounted on the front side of the fixed plate 2 through the motor box at the rear end, the output shaft of the rotating motor 51 is fixed with a middle shaft 52, and a plurality of clamping parts 53 are symmetrically arranged on the side surface of the middle shaft 52 as the axis. The clamping part 53 comprises a connecting rod 531 hinged on the side surface of the middle shaft 52, a partition plate 532 fixed on the end of the connecting rod 531 away from the hinged position, and an arc-shaped pressing plate 533 hinged on the side surface of the partition plate 532 away from the connecting rod 531.

The rotating clamping part 5 is used for clamping and positioning the ceramic bond grinding wheel and controlling the rotation of the ceramic bond grinding wheel. The umbrella-shaped structure of the clamping part of the rotating clamping part 5 can more firmly clamp the ceramic bond grinding wheel, and can avoid the situation that the ceramic bond grinding wheel rotates by itself during rotation, thereby reducing the finishing effect. Specifically, after the ceramic bond grinding wheel is placed between the stop plate 3 and the rotating clamping part 5, the sleeve ring 521 is twisted to drive the transmission ring 523 to move forward, the transmission ring 523 pushes the umbrella rib 534 forward, the umbrella rib 534 pushes the connecting rod 531 to move forward and makes the arc-shaped pressing plate 533 cooperate with the stop plate 3 to clamp the ceramic bond grinding wheel, and after clamping, the sleeve ring 521 is stopped from being twisted, so that the ceramic bond grinding wheel is accurately positioned to complete the subsequent finishing work.

[0035] Referring to Figure 4 The stop plate 3 is divided into a vertical part and a horizontal part, the vertical part of the stop plate 3 is two plates symmetrically arranged left and right, and a plurality of uniformly distributed balls 31 are arranged on the rear side surface of the vertical part of the stop plate 3. The stop plate 3 is used for clamping the ceramic bond grinding wheel together with the arc-shaped pressing plate 533, and under the action of the balls 31, the ceramic bond grinding wheel can rotate without generating reverse force on the arc-shaped pressing plate 533 to cause self-rotation and reduce the finishing effect.

The fixed processing part 4 is an important part for completing the trimming work of the mechanical ceramic bond grinding wheel, wherein the hole diameter processing piece 43 is used for trimming the mounting hole on the ceramic bond grinding wheel, and the trimming piece 44 is used for trimming the outer ring surface of the ceramic bond grinding wheel. Specifically, after the ceramic bond grinding wheel is positioned, the electric push rod 41 is controlled to move backward, so that the working part on the trimming piece 44 abuts against the outer ring surface of the ceramic bond grinding wheel, and then the subsequent rotary trimming can be carried out.

[0037] Referring to Figure 4 and Figure 7 , the trimming piece 44 includes a movable plate 441 hinged on the rear side of the collection plate 42, the rear side of the movable plate 441 is fixed with a gas cylinder 442, the rear end of the gas cylinder 442 is fixed with a trimming collection plate 443, the trimming collection plate 443 is sequentially installed with a grinding wheel shaping rod 444, a steel brush 445 and a scraper 446 from front to back on the right side face, and a liquid passage pipe 447 is installed on the top of the trimming collection plate 443 and above the grinding wheel shaping rod 444 through a positioning plate. The scraper 446 is provided with a pointed protrusion away from the side of the trimming collection plate 443, and the length of the steel brush 445 is greater than the lengths of the grinding wheel shaping rod 444 and the pointed protrusion. The pointed protrusion, the steel brush 445 and the grinding wheel shaping rod 444 are used for scraping, brushing and trimming the ceramic bond grinding wheel, and the overall operation can further enhance the trimming effect of the outer ring surface of the ceramic bond grinding wheel. Specifically, when the pointed protrusion, the steel brush 445 and the grinding wheel shaping rod 444 abut against the outer ring surface of the ceramic bond grinding wheel, the rotary motor 51 is controlled to drive the clamping piece 53 to rotate the ceramic bond grinding wheel, and then the gas cylinder 442 is controlled to slowly elongate backward to drive the pointed protrusion, the steel brush 445 and the grinding wheel shaping rod 444 to move backward together to complete the overall trimming of the outer ring surface of the ceramic bond grinding wheel.

[0038] Referring to Figure 4 and Figure 6The movable plate 441 is slidably connected with a sliding block near the side of the aperture processing piece 43, the sliding block is hingedly connected with a threaded rod 448 near the side of the aperture processing piece 43, two threaded rods 448 are threadedly connected with a threaded sleeve rod 449 and the threaded directions of the two threaded rods 448 are opposite; the horizontal part of the stop plate 3 is fixed with a positioning block 32 at the position of the threaded sleeve rod 449, the positioning block 32 is below the aperture processing piece 43 and is rotationally matched with the threaded sleeve rod 449. The cooperation of the threaded rod 448 and the threaded sleeve rod 449 makes the inclination angles between the two movable plates 441 and the collection plate 42 the same, and can support the inclined movable plate 441, preventing the trimming piece 44 from expanding outward due to the outward thrust of the outer ring surface of the ceramic bond grinding wheel when the cylinder 442 is stretched backward, specifically, when the trimming piece 44 on one side is controlled to open, the threaded rod 448 on this side will screw the threaded sleeve rod 449 under the action of the sliding block and the thread, since the threaded rod 448 on the other side cannot rotate, the threaded sleeve rod 449 will drive the threaded rod 448 on the other side to move and expand the trimming piece 44 on the other side synchronously.

[0039] Referring to Figure 4 The collection plate 42 is fixed with a limiting plate 45 on the rear side and between the aperture processing piece 43 and the trimming piece 44, and the collection plate 42 is fixed with a fan-shaped scale disc 46 on the limiting plate 45 above the side of the aperture processing piece 43. The limiting plate 45 is used to limit the position of the trimming piece 44, preventing the trimming piece 44 from contacting the vertical part of the stop plate 3 and damaging important components on the trimming piece 44, affecting the use of the machine, and the fan-shaped scale disc 46 is used to accurately control the angle of the trimming piece 44, so as to accurately trim the slope of the outer ring surface of the ceramic bond grinding wheel.

[0040] Referring to Figure 4 and Figure 5The aperture processing piece 43 comprises an aperture processing rod 431 fixed on the rear side of the collection plate 42, the outer front end of the aperture processing rod 431 is provided with a fine adjustment thread, the aperture processing rod 431 is threadedly connected with a fine adjustment ring 432 at the side and at the fine adjustment thread, the rear end of the fine adjustment ring 432 is fixed with a fine adjustment sliding ring 433, the rear end of the fine adjustment sliding ring 433 is rotationally connected with a fine adjustment transmission ring 434, the aperture processing rod 431 is provided with a sliding groove penetrating therethrough at the rear side of the fine adjustment thread, the middle part of the fine adjustment transmission ring 434 is fixedly provided with a sliding rod penetrating the sliding groove, and the fine adjustment transmission ring 434 is slidingly matched with the aperture processing rod 431 through the sliding rod. The middle part of the aperture processing rod 431 is uniformly provided with a plurality of outward extending blocks 436, each outward extending block 436 is slidingly matched with the aperture processing rod 431 and extends to the outer side of the circumference of the aperture processing rod 431, the aperture processing rod 431 is a hollow structure at the position of the outward extending blocks 436, and each outward extending block 436 is provided with a pressure receiving slope on the side in the aperture processing rod 431; the middle part of the aperture processing rod 431 is provided with a push rod 435 sliding forward and backward, the front end of the push rod 435 is fixed on the rear side of the sliding rod in the middle part of the fine adjustment transmission ring 434, the rear end of the push rod 435 is fixed with an abutting block 437, and the rear end of the abutting block 437 is provided with a pressure receiving slope corresponding to the pressure receiving slope on the outward extending block 436.

Specifically, after the extension amount of the electric push rod 41 and the inclination angle between the trimming piece 44 and the collection plate 42 are adjusted, the fine adjustment ring 432 is rotated, the fine adjustment ring 432 moves backward under the action of the thread, thereby driving the fine adjustment transmission ring 434 to move backward, the fine adjustment transmission ring 434 drives the push rod 435 to move backward, thereby causing the abutting block 437 to drive the outward extending block 436 to expand outward, and the abutting block 437 abuts against the inner wall of the mounting hole of the vitrified bond grinding wheel, so that the fine adjustment ring 432 can be stopped from being rotated, and the rotary motor 51 drives the vitrified bond grinding wheel to rotate, so as to complete the trimming of the vitrified bond grinding wheel and the aperture processing of the mounting hole.
