[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figures 1 to 5 shown, the present invention provides a combined brazed superhard abrasive wheel fixture suitable for ultra-high speed grinding, including a grinding disc 1, a support frame 2 and a connecting block 3. A circular hole is provided at the top end of the support frame 2. A slide bar 201 is slidably connected inside the circular hole of the support frame 2. A pressing plate 203 is tightly arranged at the bottom end of the slide bar 201. A support pin 204 is tightly arranged at the bottom end of the pressing plate 203. An arc-shaped groove is provided at the front end of the support frame 2. The support pin 204 slides inside the arc-shaped groove at the front end of the support frame 2. A rotating rod 205 is sleeved outside the support pin 204. The rotating rod 205 slides inside the cavity of the support frame 2. The bottom end of the rotating rod 205 is rotatably connected to a rotating shaft 206. The outside of the rotating shaft 206 is rotatably connected to a rotating arm 207. The other end of the rotating arm 207 is rotatably connected to a rotating seat 208. The bottom end of the rotating seat 208 abuts against the top end of the grinding disc 1. The grinding disc 1 is tightened by the rotating rotating arm 207, so as to tighten the grinding disc 1 and the rotating arm 207.

[0020] Specifically, a threaded groove is provided at the front end of the connecting block 3. A rotating pin 302 is screwed inside the threaded groove of the connecting block 3. A rotating plate 303 is sleeved outside the rotating pin 302. The other end of the rotating plate 303 is tightly arranged with a telescopic rod 304. A first spring 305 is sleeved outside the telescopic rod 304. By pulling the rotating pin 302, the rotating pin 302 pushes the rotating plate 303 to move towards the connecting block 3.

[0021] Further, the other end of the first spring 305 is tightly abutted against a support plate 306. The support plate 306 abuts against the front end of the connecting block 3 and is pressed against the front side of the support plate 306 by the force of the rotating plate 303, thereby tightly abutting the connecting block 3 to move towards the polishing disc 1.

[0022] Furthermore, a scraper 307 is fixedly connected to the rear side of the connecting block 3. A connecting rod 301 is fixedly connected through the rear side of the connecting block 3. The connecting block 3 penetrates through the connecting rod 301. By tightly abutting the connecting block 3, the scraper 307 is pushed to approach the polishing disc 1.

[0023] It should be noted that a sliding plate 401 is tightly abutted against the rear side of the connecting block 3. The outer side of the sliding plate 401 is slidably connected to a chute frame 4. A fixed seat 402 is fixedly connected to the right bottom end of the sliding plate 401. An extension block 404 is fixedly connected to the front end of the fixed seat 402. A second spring 403 is sleeved on the outer side of the extension block 404. At this time, the second spring 403 on the outer side of the extension block 404 on the outer side of the fixed seat 402 at the right bottom end of the sliding plate 401 undergoes compressive deformation, thereby tightly abutting the extension block 404 to slide outward, preventing the scraper 307 on the outer side of the connecting block 3 from damaging the polishing disc 1.

[0024] It is worth introducing that a base 202 is sleeved on the outer side of the sliding rod 201, and a base 5 is sleeved on the outer side of the base 202. By fitting the base 202 inside the base 5, the polishing disc 1 is supported.

[0025] First, the staff fits the connecting block 3 against the outer side of the polishing disc 1 and rotates the rotating pin 302 at the front end of the connecting block 3. At this time, the rotating pin 302 rotates to drive the outer connecting rod 301 to approach the polishing disc 1. And when the rotating pin 302 approaches the connecting block 3, at this time, the rotating plate 303 on the outer side of the rotating pin 302 abuts against the telescopic rod 304 and squeezes the first spring 305 to approach the support plate 306. And the support plate 306 squeezes the front end of the connecting block 3. When the connecting blocks 3 on both sides of the connecting rod 301 approach the polishing disc 1, when the rotating pin 302 rotates too close to the polishing disc 1, the sliding plate 401 at the rear bottom end of the connecting block 3 abuts against the connecting block 3. At this time, the force from the outer side of the connecting block 3 squeezes the sliding plate 401 to slide inside the chute frame 4, pushing the sliding plate 401 towards the inner center position. At this time, the second spring 403 on the outer side of the extension block 404 on the outer side of the fixed seat 402 at the right bottom end of the sliding plate 401 undergoes compressive deformation, thereby tightly abutting the extension block 404 to slide outward, preventing the scraper 307 on the outer side of the connecting block 3 from damaging the polishing disc 1.

[0026] When the scraper 307 at the bottom of the connecting block 3 abuts against the grinding disc 1, place the support frame 2 in the circular groove of the grinding disc 1, and press down the sliding rod 201. At this time, the sliding rod 201 abuts against the pressing plate 203, and the pressing plate 203 abuts against the support pin 204. At this time, the support pin 204 slides in the inner chute of the support frame 2, and the support pin 204 drives the rotating rod 205 to slide downward. During the downward sliding process, the rotating rod 205 deflects outward. A rotating shaft 206 is rotatably connected to the bottom end of the rotating rod 205, and the rotating shaft 206 penetrates the rotating arm 207 outside the rotating rod 205. At this time, the rotating arm 207 rotates under the drive of the rotating shaft 206 and rotates in cooperation with the rotating seat 208 at the top of the grinding disc 1. At this time, the rotating arm 207 abuts against the outside of the grinding disc 1, so as to be tightened, and the sliding rod 201 is sleeved outside the base 202, and the base 202 is inserted into the inside of the base 5.
