[0043] The working principle of the present invention is:

[0044] The base frame 1 supports and fixes the present invention, and the operation board 1-1 can be used to place operation tools, unpolished blanks and other items. When the clamp bracket 2 is used, the sliding plate 2-3 can slide laterally in the bracket slide rail 2-2, and the upper arm 2-4 and the lower arm 2-7 pass through the upper hinge frame 2-5 and the lower hinge frame 2 The hinge between -6 can realize relative rotation along the hinge axis; rotating the screw 2-9 can control the connecting block 2-10 to drive the connecting arm 2-11 to move up and down. When the reciprocating control mechanism 3 is used, the input shaft 3- 15 drives the driving bevel gear 13-14 to rotate, the driving bevel gear 13-14 drives the driven bevel gear 13-13 to rotate, and the driven bevel gear 13- 13 drives the driving pulley shaft 13 -11 turns, the driving pulley shaft 13-11 drives the driving pulley 13-10 to rotate, the driving pulley 13-10 drives the driven pulley 13-9 to rotate, and the driven pulley 13-9 drives the turntable through the turntable shaft 13-8 13-7 rotation; turntable 13-7 will drive the eccentric shaft 3-6 when it rotates, make a circular motion around the center of the turntable 13-7, when the eccentric shaft 3-6 makes a circular motion, it will drive the reciprocating gear through the rocker arm 3-5 3-3 makes a reciprocating circular motion around the axis of the reciprocating gear shaft 3-4. When the reciprocating gear 3-3 makes a reciprocating circular motion, it will drive the rack 3-1 to move around through the meshing relationship, and the rack 3-1 will move around Drive the upper arm 2-4 to move left and right to make a linear reciprocating motion; when the lifting jig 4 is used, the lifting slider 4-1 can slide up and down in the lower arm 2-7, and the connecting arm 2 can be controlled by rotating the screw 2-9 -11 Drive the lifting slider 4- 1 to raise and lower, thereby adjusting the height of the chuck 4-5 to cope with different sizes of height, and use Feeding method when grinding; by rotating the two-way screw 14-4, the two sliding frames 4-3 can be relatively close to or away from the fixture rail 4-2, and the two sliding frames 4-3 will drive the two chucks 4 -5 movement, in order to clamp or loosen the ceramic products to be processed by rotating the two-way screw 14-4. When the transmission wheel 5 is used, the driven gear 15-4 drives the worm 5-2 to rotate, and the worm 5-2 drives the worm wheel 5-1 to rotate. Since one of the worm wheels 5-1 is fixedly connected to the other end of the input shaft 3-15, The worm gear 5-1 and the matched worm 5-2 are unidirectional transmission and can be self-locked, so the input shaft 3-15 is unidirectional input, when and When the worm wheel 5-1 connected to the input shaft 3-15 does not rotate, the input shaft 3-15 cannot rotate, so that when the power source is lost, the turntable 13-7 cannot rotate autonomously. When the grinding device 7 is used, the motor 7-1 is connected to the power supply and the switch through the wire and turned on. The motor 7-1 drives the driving gear II7-2 to rotate, the driving gear II7-2 drives the driven gear 117-3 to rotate, and the driven gear II7 -3 drives the driving pulley II7-5 to rotate through the transmission shaft 7-4, the driving pulley II7-5 drives the driven pulley II7-6 to rotate, and the driven pulley II7-6 drives the grinding disc frame 7 through the grinding disc shaft 7-7 -8 Rotate, the grinding disc holder 7-8 can be fixedly connected to the grinding discs 7-9 of different thickness and roughness according to actual needs; rotate the screw 2-9 to raise or lower the lifting slider 4-1 to adjust the two chucks 4 The height of -5 makes the bottom of the ceramic products held by the two chucks 4-5 contact with the rotating grinding disc 7-9 and starts grinding, at this time the transmission shaft 7-4 drives the toggle switch 6 to toggle The switch 6 drives one of the driven gears 15-4 to rotate, and one of the worm gears 5-1 drives the input shaft 3-15 to rotate, so that the reciprocating control mechanism 3 starts to work, and the two chucks 4-5 are installed by the above linkage The clamped ceramic products begin to reciprocate left and right while being polished, to avoid that the bottom surface of the ceramic products is only the same as the polishing disc 7-9 Is deep wear scar the contact surface field appears at the bottom of the ceramic article appears. When the toggle switch 6 is used, the transmission shaft 7-4 drives the central pivot 6-2 to rotate, and the central shaft 6-2 drives the central gear 6-1 to rotate, and the central gear 6-1 rotates to drive the driving gear 16-5 to rotate, Since the pivot 6-2 is rotationally connected to the shift lever 6-3, the driving gear 16-5 will rotate the shift lever 6-3 about the axis of the pivot 6-2 while rotating around its own axis, so that the driving The gear 16-5 makes a circular motion around the axis of the central gear 6-1; when the lever 6-3 rotates, it will drive the tightening screw 6-6 to slide in the arc groove on the positioning plate 6-7. When tightening the screw 6 -6 is at one end of the arc groove, the driving gear 16-5 meshes with one of the driven gears 15-4, and when the screw 6-6 is tightened at the other end of the arc groove, the driving gear 16-5 and The other driven gear 15-4 meshes the drive. When the tightening screw 6-6 is located in the middle of the arc-shaped groove, the driving gear 16-5 and the two driving gears 16-5 are not meshed. Screw in the tightening screw 6-6 The position of the tightening screw 6-6 can be fixed by tightening the tightening screw 6-6 against the positioning plate 6-7, so that the transmission object can be switched or the transmission can be interrupted. When the swing control mechanism 8 is used, another worm gear 5-1 drives the short shaft 8-1 to rotate. Since the worm gear 5-1 and the worm 5-2 are unidirectionally driven and can be self-locked, the short shaft 8-1 is also single Input, when the driven gear 15-4 of the transmission wheel 5 connected to the short shaft 8-1 meshes with the drive gear 16-5, the short shaft 8-1 will start to rotate and drive the rectangular rod 8-2 to rotate, because The reciprocating control mechanism 3 will drive the swing control mechanism 8 to move left and right. In order to ensure that the power of the swing control mechanism 8 is cut off at any time during the movement and the swing work is started, the reciprocating control mechanism 3 can drive normally, so the short shaft 8-1 The middle end is rotationally connected to the short arm 1-5, does not follow the main body of the swing control mechanism 8, the sleeve 8-3 is provided with a rectangular slot inside, and the rectangular rod 8-2 slides Connected to the rectangular groove inside the sleeve rod 8-3, the rectangular rod 8-2 can drive the sleeve rod 8-3 to rotate, so that the rectangular rod 8-2 and the sleeve rod 8-3 can slide and drive relatively, sleeve When the rod 8-3 rotates, it will drive the driving bevel gear II8-4 to rotate. When the driving bevel gear II8-4 rotates, it will drive the driven bevel gear II8-7 to rotate. The driven bevel gear II8-7 will drive the turntable through the turntable shaft II8-8 II8-9 rotation, turntable II8-9 rotation will drive the two L-shaped guide rails 8-10 to rotate around the center of the turntable ^ 8-9, so that the I-shaped sliders 8-11 in the two L-shaped guide rails 8-10 will turn around the turntable The circle center of II8-9 makes circular motion. I-shaped slider 8-11 will drive the drive arm 8-13. The adjustment block 18-14, bidirectional screw 118-15, and adjustment block 118-16 can be regarded as a straight arm. The arm 8-13 will drive the adjustment block 18-14, the two-way screw 118-15 and the adjustment block 118-16. The adjustment block 118-16 will drive the lower arm 2-7 to swing left and right through the hinge to make the two chucks 4-5 The mounted ceramic products start to swing, which can polish the arc chamfer or assist in polishing the bottom arc. Because the shape of the ceramic product is not fixed, other parts may be touched by mistake when the swing amplitude is large, so adjust the position of the I-shaped slider 8-11 from the center of the circle in the two L-shaped guide rails 8-10 to adjust the chuck 4-5 Amplitude of the swing, and after positioning screw 8-12 is tightened, it is positioned on the side of the L-shaped guide rail 8-10. After adjusting the position of the finished slider 8-11, rotate the two-way screw 118-15 to adjust. The distance between the block 18-14 and the adjustment block 118-16, adjust the lower arm 2-7 to the vertical or the required initial angle, because the short axis 8-1 is a one-way input, so when the short axis 8-1 is matched When there is no power input to the worm gear 5-1, the turntable II8-9 cannot rotate, so that the lower arm 2-7 and the upper arm 2-4 cannot rotate relatively, so that the lower arm 2-7 and the upper arm 2-4 are performing linear reciprocating motion At the time, it remains relatively fixed and cannot be rotated.
