[0023] The working principle of the above embodiment is as follows: When clamping the workpiece bodies 14, the three workpiece bodies 14 are manually placed on the upper side of the two round rods 10. At this time, the positions of the three workpiece bodies 14 are as follows: Figure 2 As shown, an upward thrust is then manually applied to the connecting block 12. Under the guidance of the connecting plate 8, looking from right to left, the connecting block 12 rotates counterclockwise, and the connecting block 12 drives the two round rods 2 11 to move until one of the round rods 2 11 contacts the magnet 13, and the magnet 13 attracts the round rod 2 11 by magnetic force. At this time, the two round rods 2 11 just move to the top of the workpiece body 14, that is, the two round rods 10 and the two round rods 2 11 are distributed around the three workpiece bodies 14, and the three workpiece bodies 14 are positioned at the same time by the cooperation of the two round rods 10 and the two round rods 2 11, so that the axes of the three workpiece bodies 14 are aligned with each other, and then, the motor 205 is started, and the motor 205 drives the screw rod 206 to rotate, and the screw rod 206 drives the rightmost slider 5 to move to the left, and the slider 5 drives the ring 6 and the fixed block 1 7 thereon to move to the left, so that the rightmost fixed block 1 7 contacts the rightmost fixed block 1 The workpiece body 14 is then pushed to the left by the rightmost fixed block 7, so that the rightmost workpiece body 14 contacts the second fixed block 7 from right to left, and pushes the second fixed block 7 from right to left to move left, so that the second fixed block 7 from right to left pushes the middle workpiece body 14 to move left, so that the middle workpiece body 14 contacts the third fixed block 7 from right to left, and pushes the third fixed block 7 from right to left to move left, so that the third fixed block 7 from right to left pushes the leftmost workpiece body 14 onto the leftmost fixed block 7, thereby clamping the three workpiece bodies 14 at the same time through the cooperation of the four fixed blocks 7 to complete the clamping operation. In this process, the three workpiece bodies 14 are limited by the cooperation of the two round bars 10 and the two round bars 2 11 to prevent the workpiece bodies 14 from being offset due to the clamping extrusion force.

[0024] After the clamping is completed, the connecting block 12 and the round rod 2 11 are manually pushed back. When the round rod 2 11 moves back to its original position, the connecting block 12 is manually continued to be pushed. The connecting block 12 drives the round rod 2 11 to move, so that the round rod 2 11 drives the connecting plate 8 to move downward and compresses the spring 1 9. When the connecting plate 8 moves downward, its lower edge contacts the inclined surface of the fixed block 209. The connecting plate 8 continues to move downward, which will force the fixed block 209 to move toward the side away from the side plate 3 and stretch the spring 3 2010. When the through groove 91 on the side plate 3 is aligned with the fixed block 209, the spring 3 2010 rebounds and drives the fixed block 209 to move, so that the fixed block 209 is inserted into the through groove 91. At this time, the connecting block 12 is manually stopped. The connecting plate 8 is fixed by the fixing block 209. During this process, the connecting plate 8 will also drive the round rod 10 and the round rod 2 11 to move downward, so that the round rod 10 and the round rod 2 11 move downward away from the workpiece body 14. Then the telescopic cylinder 101 drives the electric grinding roller 102 to move toward the workpiece body 14, so that the electric grinding roller 102 contacts the workpiece body 14. At the same time, the motor 1 201 is started, and the motor 1 201 drives the column gear 202 to rotate, the column gear 202 drives the spur gear 203 to rotate, the spur gear 203 drives the gear ring 204 to rotate, the gear ring 204 drives the four fixing blocks 1 7 to rotate synchronously, and the four fixing blocks 1 7 drive the three workpiece bodies 14 to rotate synchronously, so that the three workpiece bodies 14 are polished by the electric grinding roller 102 at the same time. During the grinding operation, in the clamping process, the horizontally moving slider 5 will compress the spring 207. After the grinding is completed, the electric grinding roller 102 is turned off, and the telescopic cylinder 101 drives the electric grinding roller 102 to move back to its original position, and the motor 201 is turned off to stop the fixed block 7 from driving the workpiece body 14 to rotate, and then the motor 205 drives the screw rod 206 to rotate, and the screw rod 206 drives the rightmost slider 5 to move back to its original position, so that the spring 207 in the compressed state rebounds and drives the two middle sliders 5 to reset, so that the fixed block 7 stops clamping the workpiece body 14, and then the polished workpiece body 14 is manually taken out, and the fixed block 209 is pulled again to pull the fixed block 209 out of the transparent groove 91, so that the spring 9 rebounds and drives the connecting plate 8 and its The parts on the workpieces move back to their original positions to complete the reset operation. When in use, the three workpiece bodies 14 only need to be placed on the two round rods 10, and then the connecting block 12 can be pushed up and down once to complete the clamping operation of the three workpiece bodies 14 at the same time. The operation is convenient, and the three workpiece bodies 14 will not be offset during the clamping process, thereby avoiding the problems of difficulty in clamping multiple workpiece bodies 14 at the same time and difficulty in alignment in the prior art. In the process of pushing the connecting block 12 downward, the connecting block 12 can also control the round rod 10 and the round rod 2 11 to stay away from the workpiece body 14 to prevent the round rod 10 and the round rod 2 11 from interfering with the grinding of the workpiece body 14, and this process can be achieved by manually increasing the downward movement stroke of the connecting block 12 without additional control.Further reducing the difficulty of manual operation will help improve convenience.

[0025] It should be understood that when the slider 5 slides on the connecting frame 4 , the slider 5 drives the parts thereon to move together, that is, the slider 5 drives the spur gear 203 to slide left and right on the column gear 202 , so that the spur gear 203 is always meshed with the column gear 202 .

[0026] According to the above working principle, we know that the present invention has the following effects: Manually, one only needs to place the three workpiece bodies 14 on the two round rods 10, and then push the connecting block 12 up and down once, so as to complete the clamping operation of the three workpiece bodies 14 at the same time. The operation is convenient, and the three workpiece bodies 14 will not be offset during the clamping process, thereby avoiding the difficulties in operating and aligning multiple workpiece bodies 14 at the same time in the prior art. In the process of pushing the connecting block 12 downward, the connecting block 12 can also control the round rods 10 and the round rods 11 to stay away from the workpiece bodies 14 to prevent the round rods 10 and the round rods 11 from interfering with the grinding of the workpiece bodies 14. Moreover, this process can be achieved by manually increasing the downward movement stroke of the connecting block 12 without additional control, further reducing the difficulty of manual operation and helping to improve convenience. Example

[0027] On the basis of Example 1, Figure 3-Figure 7 As shown, the vertical surface where the connecting plate 8 contacts the corresponding side plate 3 is set as an inclined surface.

[0028] It also includes a pull rod 2011; each fixed block 209 is bolted with a pull rod 2011, and the pull rod 2011 is manually held and then the fixed block 209 is pulled to move through the pull rod 2011, which is very convenient.

[0029] It also includes a fixed block three 2012; the fixed blocks 17 at both ends are fixedly connected to the opposite sides with a fixed block three 2012; the fixed blocks 17 located outside the two ends are fixedly connected to both sides with a fixed block three 2012; each fixed block three 2012 is provided with a plurality of grooves, which is beneficial to increase the friction force, thereby improving the fixing effect of the workpiece body 14.

[0030] The working principle of the above embodiment is as follows: After the polishing described in Example 1 is completed: The debris generated by the rough grinding of the workpiece body 14 is relatively sharp, and the sharp debris will be contaminated on the surface of the workpiece body 14 after the grinding. At the same time, the surface roughness of the workpiece body 14 is large after the rough grinding is completed, especially sharp burrs will remain at the edge of the workpiece body 14, which will cause the fingers to be easily stabbed by the sharp debris and scratched by the burrs when manually taking out the polished workpiece body 14. First, the external storage box is manually set under the slide 2. When the fixed block 7 stops clamping the workpiece body 14, the workpiece body 14 falls back onto the two round rods 10, and then the fixed block 209 is manually pulled once to make the fixed block 209 away from the transparent groove 91, so that the fixed block 209 stops fixing the connecting plate 8, and then the spring 9 rebounds to drive the connecting plate 8 to move upward back to its original position. In this process, The vertical surface where the connecting plate 8 contacts the corresponding side plate 3 is set as an inclined surface, so that the connecting plate 8 slides obliquely forward. When the connecting plate 8 moves to the extreme position and stops suddenly, the workpiece body 14 supported on the two round rods 10 continues to move due to inertia, thereby throwing the polished workpiece body 14 obliquely forward into the slide 2. At this time, the workpiece body 14 is buffered and protected by the buffer pad on the slide 2, and then falls along the slide 2 to the external storage box to complete the removal operation. When in use, the connecting plate 8 and the parts thereon can throw the polished workpiece body 14 forward into the slide 2 during the resetting process to complete the material removal operation. There is no need for manual removal operation to prevent manual fingers from being pierced by debris and scratched by burrs. There is no need to set up other material removal mechanisms for removal operations, and the structure is ingenious.

[0031] According to the above working principle, we know that the present invention has the following effects: During the resetting process, the connecting plate 8 and the parts thereon can throw the polished workpiece body 14 forward into the slide 2 to complete the material removal operation. There is no need for manual removal operation, which prevents manual fingers from being pierced by debris and scratched by burrs. There is no need to set up other material removal mechanisms for removal operations. The structure is ingenious.

[0032] On the basis of the above technical effects, the present invention also has the following advantages: First, the pull rod 2011 is manually held, and then the fixed block 209 is pulled by the pull rod 2011 to move, which is very convenient.

[0033] Second, the workpiece body 14 is clamped and fixed by the fixing block three 2012 instead of the fixing block one 7. The fixing block three 2012 is provided with a plurality of grooves, which is beneficial to increase the friction force, thereby improving the fixing effect of the workpiece body 14. Example

[0034] On the basis of Example 2, Figure 8 and Fig. 9As shown, it also includes a second magnet 2013; a second magnet 2013 is fixedly connected to the upper side of each connecting plate 8; and a second magnet 2013 is also fixedly connected to each side plate 3.

[0035] It also includes a pressure plate 2014; each connecting plate 8 has a pressure plate 2014 detachably connected to the upper side; each side plate 3 also has a pressure plate 2014 detachably connected, and the pressure plate 2014 is made of alloy material; every two adjacent pressure plates 2014 are in contact with each other; each pressure plate 2014 is in contact with the corresponding magnet 2 2013, and the magnet 2 2013 is fixed and protected by the pressure plate 2014; a square groove is provided in the middle of the pressure plate 2014.

[0036] The connecting block 12 is made of soft rubber material.

[0037] The working principle of the above embodiment is as follows: In the process described in Example 2, when the spring 9 rebounds and drives the connecting plate 8 to move upward and return to its original position: The connecting plate 8 drives the second magnet 2013 to move upward. In the final stage of the upward movement of the connecting plate 8, the upper and lower adjacent magnets 2013 gradually approach each other. At this time, the upper and lower adjacent magnets 2013 generate magnetic attraction, which acts on the connecting plate 8, thereby increasing the movement speed of the connecting plate 8 in the final stage, which is more conducive to throwing out the polished workpiece body 14, and after the connecting plate 8 moves to the extreme position, the upper and lower adjacent magnets 2013 are tightly attracted by magnetic force, thereby avoiding the rebound phenomenon of the connecting plate 8 due to impact, and the connecting plate 8 and the parts thereon can be immediately stopped, which is conducive to the next round of clamping and polishing operation, thereby improving efficiency. In this process, the second magnet 2013 is protected by the pressure plate 2014 to avoid damage caused by high-speed impact of the upper and lower adjacent magnets 2013.

[0038] According to the above working principle, we know that the present invention has the following effects: The magnetic attraction force generated by the second magnet 2013 acts on the connecting plate 8, thereby increasing the movement speed of the connecting plate 8 in the final stage, which is more conducive to ejecting the polished workpiece body 14. At the same time, during the resetting process, the upper and lower adjacent magnets 2013 are tightly attracted by magnetic force, so that the connecting plate 8 and the parts thereon can be immediately stationary, which is conducive to the next round of clamping and polishing operations, thereby improving efficiency. At the same time, the second magnet 2013 is protected by the pressure plate 2014 to prevent the upper and lower adjacent magnets 2013 from being damaged by high-speed collision.
