[0022] See also Figure 1-Figure 4 , the utility model provides an embodiment: a grinding and polishing structure for producing miniaturized high-definition video connectors, comprising a processing table 1, a grinding and polishing box 2 is installed on one side of the processing table 1;

[0023] A debris collection box 11 is installed on the side of the grinding and polishing box 2 away from the processing table 1, and the interior of the debris collection box 11 is communicated with one end of the processing channel 3, and a dust suction fan 14 is provided on the side of the debris collection box 11 away from the processing channel 3, and a sealing cover 12 is installed at the bottom end of the debris collection box 11, and a magnetic rod 13 is installed at the top end of the sealing cover 12, and the top end of the magnetic rod 13 extends to the interior of the debris collection box 11 and a velvet roller 15 is evenly installed on the outside;

[0024] The sealing cover 12 is threadedly connected to the debris collection box 11. Five groups of velvet rollers 15 are provided, and each group has four velvet rollers. The velvet rollers 15 are distributed in an annular shape with equal intervals on the magnetic rod 13.

[0025] Specifically, Figure 1 , Figure 4 As shown, when in use, the dust suction fan 14 and the magnetic rod 13 are used to attract the debris generated during the polishing process to the inside of the debris collection box 11 to achieve the function of collecting the debris;

[0026] A processing channel 3 is opened transversely inside the grinding and polishing box 2, and electric polishing wheels 4 are arranged at both ends of the processing channel 3, and the interval between the electric polishing wheels 4 is adapted to the diameter of the video connector pin 17. Two guide plates 5 are arranged oppositely on both sides of the top of the processing table 1, and slide grooves 6 are opened on the opposite sides of the guide plates 5. A placement plate 7 is connected between the slide grooves 6, and the top of the placement plate 7 is evenly provided with limiting grooves 16, and the video connector pins 17 are installed inside the limiting grooves 16. The width of the limiting grooves 16 is greater than the diameter of the video connector pin 17. A movable pressing plate 8 is arranged above the placement plate 7, and guide holes 23 are opened on both sides of the movable pressing plate 8, and guide rods 18 are penetrated inside the guide holes 23.

[0027] The diameter of the guide rod 18 is adapted to the width of the guide hole 23. The top of the guide rod 18 is connected to a pressing block 19 via a bolt 20, and both sides of the bottom of the pressing block 19 abut against the top of the movable pressing plate 8.

[0028] Specifically, Figure 2 , Figure 3 As shown, when in use, the guide rod 18 and the guide hole 23 are used to limit and guide the left and right movement of the movable pressing plate 8, so as to ensure the movement stability of the movable pressing plate 8, and the pressing block 19 is used to make the movable pressing plate 8 generate downward pressure, so that it can cooperate with the placement plate 7 and the limiting groove 16 to limit the video connector pin 17, and the friction effect is used to make the reciprocating movement of the movable pressing plate 8 drive the video connector pin 17 to rotate inside the limiting groove 16;

[0029] The bottom ends of the guide rods 18 are connected to the top ends of the placement plates 7, a silicone layer is provided at the bottom ends of the movable pressing plates 8, and the silicone layer abuts against one side of the video connector pin 17, handles 9 are installed at both ends of the placement plates 7 away from the processing channel 3, and a linkage mechanism 10 is connected between one side of the placement plates 7 between the handles 9 and one side of the movable pressing plates 8, so that when the placement plates 7 drive the video connector pin 17 to approach the electric polishing wheel 4, it can simultaneously drive the movable pressing plates 8 to reciprocate left and right, thereby causing the video connector pin 17 to rotate inside the limiting groove 16;

[0030] The linkage mechanism 10 includes a support plate 1001 installed on the outside of the placement plate 7, and a rotating shaft 1002 is longitudinally penetrated through the outer end of the support plate 1001, and a rotating disk 1003 is installed on the top of the rotating shaft 1002, and an eccentric shaft 1004 is installed on one side of the top of the rotating disk 1003, and a fixed plate 1005 is correspondingly installed on the outer side of the movable pressing plate 8 above the support plate 1001, and a through hole 1006 is opened inside the fixed plate 1005, and the top of the eccentric shaft 1004 passes through the inside of the through hole 1006;

[0031] The support plate 1001 is located on the central axis of the linkage mechanism 10, and the length of the through hole 1006 is adapted to the rotation diameter of the eccentric shaft 1004;

[0032] A gear 21 is installed at the bottom end of the rotating shaft 1002, and a toothed plate 22 is meshed on one side of the gear 21. Both ends of the toothed plate 22 are connected to the top of the processing table 1 through a supporting block. The diameter of the gear 21 is smaller than the diameter of the rotating disk 1003.

[0033] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when in use, the meshing effect of the gear 21 and the tooth plate 22 is utilized to drive the turntable 1003 to rotate continuously during the forward movement of the placement plate 7, and the through hole 1006 and the eccentric shaft 1004 are coordinated to drive the fixed plate 1005 to reciprocate left and right, so that the movable pressure plate 8 moves synchronously, thereby realizing the rotation effect of the video connector pin 17 inside the limit slot 16.

[0034] Working principle: When the utility model is used, firstly, the video connector pin 17 is horizontally inserted into the interior of the limiting groove 16, and the video connector pin 17 is clamped and fixed by the placement plate 7 and the movable pressure plate 8 in the upper and lower directions with the action of the movable pressure plate 8, and the handle 9 is pushed to make the placement plate 7 slide along the slide groove 6, so that the video connector pin 17 enters the interior of the processing channel 3, and the electric polishing wheel 4 is started to polish the video connector pin 17 front and back;

[0035] Secondly, during the forward movement of the placement plate 7, since the gear 21 is always meshed with the tooth plate 22, the gear 21 rotates, and the rotating shaft 1002 rotates synchronously, so as to drive the turntable 1003 to rotate, thereby rotating the eccentric shaft 1004. Since the top end of the eccentric shaft 1004 is always located inside the through hole 1006, the eccentric shaft 1004 drives the fixed plate 1005 to reciprocate left and right, so that the movable pressing plate 8 reciprocates left and right along the outside of the guide rod 18. Since the silicone layer abuts against the outer wall of the video connector pin 17, the left and right movement of the movable pressing plate 8 can drive the video connector pin 17 to rotate inside the limiting groove 16, so that the electric polishing wheel 4 can comprehensively grind and polish the outer wall of the video connector pin 17 to improve the polishing quality;

[0036] Finally, during the polishing process, the dust suction fan 14 is started synchronously to generate suction to the interior so as to suck the debris generated during the polishing process into the debris collection box 11. Due to the magnetism of the magnetic bar 13, the magnetic bar 13 attracts the debris, and combined with the action of the fluff roller 15, the debris is intercepted. By rotating the sealing cover 12, it is separated from the debris collection box 11, thereby facilitating the removal of the magnetic bar 13 from the interior of the debris collection box 11 and cleaning it.
