[0014] A guide shaft is fixedly installed in the middle of the through slot, a folding plate is arranged outside the guide shaft, the middle of the folding plate is rotatably connected with the pick-and-place cylinder, and the lower part of the pick-and-place cylinder is hinged with the inclined plate.

[0015] Another object of the present invention is to provide an implant grinding method, comprising the following steps: S1: Implant placement: The motor is turned on to drive the rotating part to rotate, and when the rotating part rotates, the rotating block drives the swing frame to swing left and right, and when the swing frame swings, the connecting block drives the swing part to rotate, and when the swing part rotates, it drives the top plate to rotate synchronously, and when the top plate rotates left and right, it drives the pick-and-place cylinder to adsorb and clamp the implant placed on the magnetic block, and then moves the implant to the disc, so as to complete the placement and installation of the implant on the disc of multiple stations, and then the telescopic rod is turned on to drive the tooth plate to move, and when the tooth plate moves, it drives the middle wheel to rotate, and when the middle wheel rotates, the regulating disk is used to make multiple fasteners approach each other, so as to clamp and fix the implant placed on the supporting plate for subsequent grinding; S2: Implant grinding: When the fixed implant rotates to the bottom of the support plate with the processing table, the adjusting rod is rotated to make the arc panel close to the outside of the implant, and then the electric slider is turned on to drive the disc to rotate. When the disc rotates, it drives the implant to rub against the grinding knife, so that the outside of the implant is ground. When the disc rotates, multiple fasteners intermittently contact the wedge block, so that the special-shaped rod moves up and down. At this time, the special-shaped rod pressurizes the gas in the air cylinder into the water injection tank through the inflation pipe, and finally the water in the water injection tank is discharged through the overflow hole, so that when the grinding knife performs circumferential grinding on the outside of the implant, the overflow hole injects water to the outside of the implant. First, it cools down the heat generated during grinding to avoid deformation of the workpiece due to high temperature. Second, it can play a lubricating role, making the grinding process more streamlined and reducing tool wear. Third, it cleans and reduces dust generated during the grinding process. S3: Implant removal: When the polished implant is moved to the bottom of the material removal unit, the fastener releases the clamping of the implant, and then the telescopic plate retracts. At this time, the splint clamps the implant, the telescopic plate pushes up, and then the steering wheel rotates to the top of the collection box, and the two splints move away from each other. At this time, the polished implant falls into the collection box for collection.

[0016] Beneficial effects of the present invention: 1. The present invention drives the processing table to rotate by turning on the motor, so that multiple discs can be rotated to the bottom of the installation unit at one time. The installation unit places the implant on the supporting plate below for grinding. When the implant is ground, the processing table rotates to move the ground implant to the bottom of the material removal unit, and finally the material removal unit takes out the ground implant.

[0017] 2. The present invention moves the pick-up and placement tube downward, which drives the bottom of the implant to contact and magnetically attract the supporting plate when the pick-up and placement tube is moved downward. As the pick-up and placement tube continues to move downward, the supporting plate generates a reaction force on the implant. At this time, the implant slides up in the inner cavity of the pick-up and placement tube under the action of the supporting plate. At this time, the implant pushes the magnetic suction cup upward, and the magnetic suction cup pulls the folding plate when it moves upward. At this time, one side of the folding plate flips outward, and when the folding plate flips outward, it simultaneously drives the inclined plate to slide outward. At this time, multiple inclined plates move away from each other to cancel the clamping of the implant. As the pick-up and placement tube continues to rise, since the magnetic force of the supporting plate is greater than the magnetic force of the magnetic suction cup, the magnetic suction cup is separated from the top of the implant, thereby completing the placement of the unground implant.

[0018] 3. The present invention opens the telescopic rod to make the toothed plate drive the middle wheel to rotate, and when the middle wheel rotates, it drives the regulating disk to rotate synchronously, and when the regulating disk rotates, multiple moving blocks slide in the regulating groove, and at this time, the fasteners on the multiple moving blocks clamp the implant.

[0019] 4. The present invention drives the disc to rotate by opening the electric slider, so that the implant rotates and then contacts the grinding knife for grinding in a circumferential direction. When the disc rotates, multiple fasteners intermittently contact the wedge block, so that the special-shaped rod moves up and down. At this time, the special-shaped rod pressurizes the gas in the air cylinder into the water injection tank through the inflation tube. Finally, the water in the water injection tank is discharged through the overflow hole, so that when the grinding knife performs circumferential grinding on the outside of the implant, the overflow hole injects water to the outside of the implant. First, it cools the heat generated during grinding to avoid deformation of the workpiece due to high temperature. Second, it can play a lubricating role to make the grinding process smoother and reduce tool wear. Third, it cleans and reduces dust generated during the grinding process.

[0020] 5. The present invention cancels the clamping of the implant through the firmware, and then the telescopic plate retracts. At this time, the splint clamps the implant, and the telescopic plate pushes up. Then the steering wheel rotates to the top of the collection box, and the two splints move away from each other. At this time, the polished implant falls into the collection box for collection. BRIEF DESCRIPTION OF THE DRAWINGS

A fastener 262 that slides in the guide frame 26 is threadedly rotatably installed on the regulating rod 261, and multiple fasteners 262 are arc-shaped on the side close to each other. A mounting unit 3 fixedly connected to the base 1 is provided on one side of the processing table 2, and a grinding unit 4 fixedly connected to the base is provided on the side of the processing table 2 away from the mounting unit 3. A material picking unit 5 fixedly connected to the base 1 is provided on the front side of the processing table 2, and a collecting box 6 placed on the base 1 is provided on one side of the material picking unit 5.

[0026] The motor is turned on to drive the processing table 2 to rotate, so that multiple discs 22 can be rotated to the bottom of the installation unit 3 at one time. The installation unit 3 places the implant on the supporting plate 252 below for grinding. When the implant is ground, the processing table 2 rotates to move the ground implant to the bottom of the material removal unit 5, and finally the material removal unit 5 takes out the ground implant.

[0027] A fixed column 241 is fixedly installed on the upper end surface of the moving block 24 away from the side of the L-shaped frame 25, and a regulating disk 27 is rotatably installed in the middle of the upper end surface of the disc 22. The regulating disk 27 is circumferentially provided with an arc groove sleeved on the fixed column 241, and a middle wheel 271 fixedly connected to the regulating disk 27 is provided on one side of the lower end surface of the disc 22. A telescopic rod 28 fixedly connected to the disc 22 is provided on one side of the middle wheel 271, and a toothed plate 29 meshing with the middle wheel 271 is fixedly installed at the telescopic end of the telescopic rod 28.

[0028] The tooth plate 29 is moved by extending and retracting the telescopic rod 28, and when the tooth plate 29 moves, it drives the middle wheel 271 to rotate. When the middle wheel 271 rotates, it drives the regulating disk 27 to rotate synchronously. When the regulating disk 27 rotates, the fixed column 241 drives multiple moving blocks 24 to slide in the corresponding regulating grooves 23, thereby adjusting the spacing between the multiple fasteners 262. When the multiple fasteners 262 are close to each other, the lower parts of the implants placed together on the multiple supporting plates 252 are clamped.

[0029] The mounting unit 3 includes a fixed frame 31, a shaped frame 32 is fixedly mounted on the top of the fixed frame 31, a cross bar 33 is transversely mounted in the middle of the shaped frame 32, a moving part 34 is sleeved on the cross bar 33, a sliding frame 341 is slidably mounted on the moving part 34, a pick-up and release cylinder 35 is fixedly mounted on the bottom of the sliding frame 341, a rotating part 36 is rotatably mounted in the middle of the fixed frame 31 through a motor, a rotating block 361 is rotatably mounted on the side of the rotating part 36 away from the fixed frame 31, a swinging frame 37 that rotates with the fixed frame 31 is slidably mounted on the outside of the rotating block 361, a swinging block 371 is slidably mounted on the middle of the upper side of the swinging frame 37, and a connecting block 372 is rotatably mounted on the side of the swinging block 371 away from the fixed frame 31.

[0030] A swing shaft 373 is fixedly installed on the side of the connecting block 372 away from the swing block 371, and a long plate 38 connected to the fixed frame 31 is provided on the front side of the connecting block 372. The swing shaft 373 penetrates and slides in the long plate 38. A swing piece 374 is fixedly installed on the side of the swing shaft 373 away from the connecting block 372. A top plate 375 rotatably connected to the sliding frame 341 is fixedly installed on the top of the swing piece 374. A rotating box 39 is installed on one side of the fixed frame 31 through a motor, and a magnetic block 391 for placing unground implants is fixedly installed in an annular direction in the rotating box 39.

[0031] When the unpolished implant is placed on the disc 22 that is rotated to the bottom of the mounting unit, the motor is turned on to drive the rotating member 36 to rotate. When the rotating member 36 rotates, it drives the swing frame 37 to swing left and right. When the swing frame 37 swings, it drives the swing shaft 373 to rotate through the connecting block 372. When the swing shaft 373 drives the top plate 375 to rotate left and right, it drives the sliding frame 341 and the moving member 34 to slide left and right on the cross bar 33. At the same time, when the sliding frame 341 slides left and right, it also drives the pick-up and place cylinder 35 to move up and down. When the pick-up and place cylinder 35 moves to the top of the rotating box 39, it then moves down to put the magnetic block 391 on The implant is picked up by adsorption. When the pick-up and placement cylinder 35 moves down, the implant contacts with multiple inclined panels 354. At this time, multiple inclined panels 354 move away from each other and contact with the magnetic suction cup 352 on the top of the pick-up and placement cylinder 35. After the magnetic suction cup 352 adsorbs the top of the pick-up and placement cylinder 35, since the magnetic force of the magnetic suction cup 352 is greater than the magnetic force of the magnetic block 391, when the pick-up and placement cylinder 35 moves up, the implant moves with the pick-up and placement cylinder 35. In addition, the implant can be clamped by the arrangement of multiple inclined panels 354 to prevent the implant from falling during movement. When the pick-up and placement cylinder 35 moves to the center above the disc 22 When the pick-up and placement cylinder 35 moves downward, the pick-up and placement cylinder 35 moves downward, and the bottom of the implant is brought into contact with the supporting plate 252 and magnetically attracted to each other. As the pick-up and placement cylinder 35 continues to move downward, the supporting plate 252 generates a reaction force on the implant. At this time, the implant slides upward in the inner cavity of the pick-up and placement cylinder 35 under the action of the supporting plate 252. At this time, the implant pushes the magnetic suction cup 352 upward, and the magnetic suction cup 352 pulls the folding plate 357 when it moves upward. At this time, one side of the folding plate 357 flips outward, and when the folding plate 357 flips outward, it simultaneously drives the inclined plate 354 to slide outward. At this time, multiple inclined plates 354 move away from each other, eliminating the implant. The clamping of the implant, as the pick-up and placement cylinder 35 continues to rise, since the magnetic force of the supporting plate 252 is greater than the magnetic force of the magnetic suction cup 352, the magnetic suction cup 352 is separated from the top of the implant, thereby completing the placement of the unground implant. When the placed implant is fixed before grinding, the telescopic rod 28 is opened to allow the toothed plate 29 to drive the middle wheel 271 to rotate. When the middle wheel 271 rotates, it simultaneously drives the regulating disk 27 to rotate. When the regulating disk 27 rotates, the multiple moving blocks 24 slide in the regulating groove 23. At this time, the fasteners 262 on the multiple moving blocks 24 clamp the implant.

[0032] The grinding unit 4 includes a stand 41, on the top of which electric push rods 42 are symmetrically mounted, a support plate 43 is fixedly mounted on the telescopic ends of the two electric push rods 42, a ring-shaped folding plate 430 is fixedly mounted on the outer edge of the lower end surface of the support plate 43, an adjusting rod 431 is threadedly mounted on the top of the support plate 43, an adjusting block 432 is threadedly mounted on the adjusting rod 431, an arc panel 44 is fixedly mounted on the lower end surface of the adjusting block 432, a middle groove 441 is vertically opened in the middle of the arc panel 44, and a grinding knife 45 is slidably mounted in the middle groove 441.

[0033] When the implant is being polished, the electric push rod 42 is turned on and pushed forward, and the support plate 43 moves down as a whole, and then the adjusting rod 431 is rotated to make the adjusting block 432 drive the arc panel 44 to be close to one side of the outer wall of the implant, and then the electric slider is turned on to drive the disc 22 to rotate, so that the implant rotates and then contacts and polishes with the grinding knife 45 in a circumferential direction. When the disc 22 rotates, multiple fasteners 262 intermittently contact the wedge block 462, so that the special-shaped rod 461 moves up and down. At this time, the special-shaped rod 461 pressurizes the gas in the air cylinder 46 into the water filling tank 47 through the inflation pipe 463, and finally the water in the water filling tank 47 is discharged through the overflow hole 48, so that when the grinding knife 45 performs circumferential polishing on the outside of the implant, the overflow hole 48 injects water to the outside of the implant. First, it cools down the heat generated during polishing to avoid deformation of the workpiece due to high temperature. Second, it can play a lubricating role, making the polishing process smoother and reducing tool wear. Third, it cleans and reduces dust generated during the polishing process.

When the rotating member 36 rotates, the swing frame 37 is driven to swing left and right through the rotating block 361. When the swing frame 37 swings, the swing member 374 is driven to rotate through the connecting block 372. When the swing member 374 rotates, it drives the top plate 375 to rotate synchronously. When the top plate 375 rotates left and right, it drives the pick-up and placement cylinder 35 to adsorb and clamp the implant placed on the magnetic block 391, and then moves the implant to the disc 22, thereby completing the placement and installation of the implant on the disc 22 of multiple stations. Then, the telescopic rod 28 is turned on to drive the tooth plate 29 to move. When the tooth plate 29 moves, it drives the middle wheel 271 to rotate. When the middle wheel 271 rotates, the regulating disk 27 makes the multiple fasteners 262 approach each other, thereby clamping and fixing the implant placed on the supporting plate 252 for subsequent grinding; S2: Implant grinding: When the fixed implant rotates to the bottom of the support plate 43 along with the processing table 2, the adjusting rod 431 is rotated to make the arc panel 44 close to the outside of the implant, and then the electric slider is turned on to drive the disc 22 to rotate. When the disc 22 rotates, it drives the implant to rub against the grinding knife 45, so that the outside of the implant is ground. When the disc 22 rotates, multiple fasteners 262 intermittently contact with the wedge block 462, so that the special-shaped rod 461 moves up and down. At this time, the special-shaped rod 461 pressurizes the gas in the air cylinder 46 into the water injection box 47 through the inflation pipe 463, and finally the water in the water injection box 47 is discharged through the overflow hole 48, so that when the grinding knife 45 performs circumferential grinding on the outside of the implant, the overflow hole 48 injects water to the outside of the implant. First, it cools down the heat generated during grinding to avoid deformation of the workpiece due to high temperature. Second, it can play a lubricating role to make the grinding process smoother and reduce tool wear. Third, it cleans and reduces dust generated during the grinding process. S3: Implant removal: When the polished implant is moved to the bottom of the material removal unit 5, the fastener 262 releases the clamping of the implant, and then the telescopic plate 51 retracts. At this time, the splint 55 clamps the implant, and the telescopic plate 51 is pushed up. Then the steering wheel 53 rotates to the top of the collection box 6, and the two splints 55 move away from each other. At this time, the polished implant falls into the collection box 6 for collection.

[0039] When the present invention is in use, the motor is turned on to drive the rotating member 36 to rotate, and when the rotating member 36 rotates, it drives the swing frame 37 to swing left and right. When the swing frame 37 swings, it drives the swing shaft 373 to rotate through the connecting block 372. When the swing shaft 373 drives the top plate 375 to rotate left and right, it drives the sliding frame 341 and the moving member 34 to slide left and right on the cross bar 33. At the same time, when the sliding frame 341 slides left and right, it also drives the pick-up and place cylinder 35 to move up and down. When the pick-up and place cylinder 35 moves to the top of the rotating box 39, it then moves down to adsorb the magnetic block 391. The implant is picked up, when the pick-and-place cylinder 35 moves downward, the implant contacts with the plurality of inclined panels 354, at which time the plurality of inclined panels 354 move away from the top of the pick-and-place cylinder 35 and contact with the magnetic suction cup 352, after the magnetic suction cup 352 adsorbs the top of the pick-and-place cylinder 35, since the magnetic force of the magnetic suction cup 352 is greater than the magnetic force of the magnetic block 391, when the pick-and-place cylinder 35 moves upward, the implant moves with the pick-and-place cylinder 35, and the plurality of inclined panels 354 can also be set to clamp the implant to prevent the implant from falling during movement; When the pick-up and placement cylinder 35 moves to the center above the disc 22, the pick-up and placement cylinder 35 moves downward, and the pick-up and placement cylinder 35 moves downward, driving the bottom of the implant to contact and magnetically attract each other with the supporting plate 252. As the pick-up and placement cylinder 35 continues to move downward, the supporting plate 252 generates a reaction force on the implant. At this time, the implant slides upward in the inner cavity of the pick-up and placement cylinder 35 under the action of the supporting plate 252. At this time, the implant pushes the magnetic suction cup 352 upward, and the magnetic suction cup 352 pulls the folding plate 357 when it moves upward. At this time, one side of the folding plate 357 flips outward, and when the folding plate 357 flips outward, it simultaneously drives the inclined plate 354 to slide outward. At this time, multiple inclined plates 354 move away from each other, canceling the clamping of the implant, and as the pick-up and placement cylinder 35 continues to rise; Since the magnetic force of the supporting plate 252 is greater than the magnetic force of the magnetic suction cup 352, the magnetic suction cup 352 is separated from the top of the implant, thereby completing the placement of the unground implant. When the placed implant is fixed before grinding, the telescopic rod 28 is opened to make the toothed plate 29 drive the middle wheel 271 to rotate. When the middle wheel 271 rotates, the regulating disk 27 is synchronously driven to rotate. When the regulating disk 27 rotates, the multiple moving blocks 24 slide in the regulating groove 23. At this time, the fasteners 262 on the multiple moving blocks 24 clamp the implant. When grinding the implant, the electric push rod 42 is turned on and pushed forward, and the support plate 43 moves downward as a whole, and then the adjusting rod 431 is rotated to make the adjusting block 432 drive the arc panel 44 to be close to one side of the outer wall of the implant, and then the electric slider is turned on to drive the disc 22 to rotate, so that the implant rotates and then contacts the grinding knife 45 in a circumferential direction for grinding. When the disc 22 rotates, multiple fasteners 262 intermittently contact the wedge block 462, so that the special-shaped rod 461 moves up and down. At this time, the special-shaped rod 461 pressurizes the gas in the air cylinder 46 into the water injection box 47 through the inflation tube 463, and finally the water in the water injection box 47 is discharged through the overflow hole 48, so that the grinding knife 45 performs circumferential grinding on the outside of the implant; The overflow hole 48 is used to inject water to the outside of the implant. Firstly, it cools down the heat generated during grinding to avoid deformation of the workpiece due to high temperature. Secondly, it can play a lubricating role to make the grinding process smoother and reduce tool wear. Thirdly, it cleans and reduces dust generated during the grinding process. When the polished implant is moved to the bottom of the material removal unit 5, the fastener 262 releases the clamping of the implant, and then the telescopic plate 51 retracts. At this time, the splint 55 clamps the implant, and the telescopic plate 51 is pushed up. Then the steering wheel 53 rotates to the top of the collection box 6, and the two splints 55 move away from each other. At this time, the polished implant falls into the collection box 6 for collection.

10. An implant grinding method, using the implant grinding device according to claim 9 to grind the implant, characterized in that: The implant grinding method comprises the following steps: S1: Implant placement: The motor is turned on to drive the rotating member (36) to rotate. When the rotating member (36) rotates, the rotating frame (37) is driven to swing left and right through the rotating block (361). When the swing frame (37) swings, the swing member (374) is driven to rotate through the connecting block (372). When the swing member (374) rotates, the top plate (375) is driven to rotate synchronously. When the top plate (375) rotates left and right, it drives the placement cylinder (35) to absorb and clamp the implant placed on the magnetic block (391), and then the implant is moved to the disk (22), thereby completing the placement and installation of the implant on the disk (22) at multiple workstations. Then, the telescopic rod (28) is turned on to drive the tooth plate (29) to move. When the tooth plate (29) moves, it drives the middle wheel (271) to rotate. When the middle wheel (271) rotates, the multiple fasteners (262) are brought closer to each other through the regulating disk (27), thereby clamping and fixing the implant placed on the supporting plate (252) for subsequent grinding. S2: Implant grinding: When the fixed implant rotates with the processing table (2) to the bottom of the support plate (43), the adjustment rod (431) is rotated to make the arc panel (44) close to the outside of the implant, and then the electric slider is turned on to drive the disc (22) to rotate. When the disc (22) rotates, the implant and the grinding knife (45) are driven to rub, so that the outside of the implant is ground. When the disc (22) rotates, multiple fasteners (262) intermittently contact with the wedge block (462), thereby causing the special-shaped rod (461) to move up and down. At this time, the special-shaped rod (461) is air-gapped. The gas in the cylinder (46) is pressurized into the water injection box (47) through the inflation tube (463), and finally the water in the water injection box (47) is discharged through the overflow hole (48), so that when the grinding knife (45) performs circumferential grinding on the outside of the implant, the overflow hole (48) injects water into the outside of the implant. Firstly, the heat generated during grinding is cooled to avoid deformation of the workpiece due to high temperature. Secondly, it can play a lubricating role to make the grinding process more streamlined and reduce tool wear. Thirdly, the dust generated during the grinding process is cleaned and dust is reduced. S3: Implant removal: When the polished implant is moved to the bottom of the material removal unit (5), the fastener (262) cancels the clamping of the implant, and then the telescopic plate (51) retracts. At this time, the clamping plate (55) clamps the implant, and the telescopic plate (51) is pushed up. Then the steering wheel (53) rotates to the top of the collection box (6), and the two clamping plates (55) move away from each other. At this time, the polished implant falls into the collection box (6) for collection.
