[0047] As shown in the figure, two rows of support rollers 31 are installed on the bracket 1 to support the positioning mechanism 5 that moves horizontally between the two transmission rollers 2 from both sides of the transmission belt 4.

[0048] like Fig. 9 , 10 As shown, there are two slides B37 moving in the direction of distribution of the two transmission rollers 2 in the box B35; the convex seat B43 and the concave seat B47 move horizontally in the slide grooves E38 on the two slides B37 along the direction perpendicular to the movement of the slides B37.

[0050] like Fig.12 As shown, the bristles 51 are densely covered with protrusions 52 for enhancing the polishing effect.

[0051] The working process of the present invention is as follows: in the vertical state, the pressure seat 54 is against the small radius arc surface of the cam 59 under the action of two springs C56 in a compressed state, and the sleeve 50 on each grinding mechanism 34 is at a certain distance from the positioning column 18 in the positioning mechanism 5 of the conveyor belt 4 in the vertical direction. The upper end of each positioning column 18 in the positioning mechanism 5 protrudes to the longest limit of the slide groove B14, and the cylindrical surface of each positioning column 18 is evenly against the corresponding limit rod 23, and the spring A22 and the spring B25 are in a stretched state. The two slide seats A9, the convex seat A13 and the concave seat A16 in each positioning mechanism 5 are in an unlocked state.

[0052] When the present invention is used to deburr and polish the socket 33 of the five-hole socket panel 32, the position of the convex seat A13 and the concave seat A16 in each positioning mechanism 5 on the conveyor belt 4 in the corresponding frame A6 is adjusted according to the relative positions of the two sockets 33 corresponding to the two-pin plug and the three sockets 33 corresponding to the three-pin plug on the five-hole socket panel 32. The adjustment process is as follows:

[0053] The two slides A9 and the convex seats A13 and concave seats A16 on the two slides A9 in each positioning mechanism 5 are manually moved so that the three positioning posts 18 on the convex seat A13 and the two positioning posts 18 on the concave seat A16 in each positioning mechanism 5 correspond one-to-one to the five sockets 33 on the socket panel 32.

[0054] After the position adjustment of the two slides A9, the convex seat A13 and the concave seat A16 on one positioning mechanism 5 is completed, the starting motor A3 drives the conveyor belt 4 to move one positioning mechanism 5 position through the two conveyor rollers 2, and the position of the two slides A9, the convex seat A13 and the concave seat A16 in the next positioning mechanism 5 is adjusted, and the adjustment steps are the same as above.

[0055] After the positions of the two slides A9, the recess A16 and the convex seat A13 in the positioning mechanism 5 are adjusted, the two bolts A8 in each positioning mechanism 5 are tightened to lock the positions of the two slides A9, and the bolts B30 on the convex seat A13 and the recess A16 are tightened so that the bolts B30 press the locking bar 28 against the guide block B27 of the recess A16 or the convex seat A13 to move the position of the convex seat A13 or the recess A16.

[0056] After all the positioning mechanisms 5 are adjusted, all the grinding mechanisms 34 are kept corresponding to one positioning mechanism 5 in the vertical direction, and the two optical sensors 48 on the convex seat B43 and the concave seat B47 on each grinding mechanism 34 are started. The two optical sensors 48 on each grinding mechanism 34 sense each other with the convex seat A13 and the concave seat A16 on the corresponding positioning mechanism 5, so that the two motors B42 and the two motors C46 in each grinding mechanism 34 are running. The two motors B42 in each grinding mechanism 34 The corresponding slide B37 is driven to move a certain range through the corresponding screw A41, and the two motors C46 drive the convex seat B43 or the concave seat B47 to move a certain range through the corresponding screw B45, so that the three sleeves 50 on the convex seat B43 on each grinding mechanism 34 correspond to the three positioning columns 18 on the convex seat A13 on the corresponding positioning mechanism 5, and the two sleeves 50 on the concave seat B47 on each grinding mechanism 34 correspond to the two positioning columns 18 on the concave seat B47 on the corresponding positioning mechanism 5.

[0057] Then, the starting motor A3 drives the conveyor belt 4 to run through the two conveyor rollers 2, and places the socket panels 32 on the positioning mechanisms 5 in turn, so that the five positioning columns 18 on each positioning mechanism 5 are respectively inserted into the five socket holes 33 on the corresponding socket panel 32 to complete the positioning and fixation of the socket panel 32.

[0058] When the socket panels 32 having the same number as the grinding mechanisms 34 are positioned and fixed and just move under the pressure seat 54 and correspond one to one with the grinding mechanisms 34, the motor A3 is stopped to keep the socket panels 32 on the positioning mechanism 5 vertically corresponding to the corresponding grinding mechanisms 34 above.

[0059] Next, the two hydraulic cylinders 58 are started to drive the housing 57 to move downward by a certain amplitude, and then the motor D60 is started. The motor D60 drives the cam 59 to rotate, and the pressure seat 54 reciprocates vertically under the joint action of the cam 59 and the two springs C56. The pressure seat 54 drives all the grinding mechanisms 34 thereon to move synchronously, and the three sleeves 50 on the convex seat B43 of each grinding mechanism 34 are reciprocatingly inserted into the three positioning columns 18 on the convex seat A13 of the corresponding positioning mechanism 5 and drive the corresponding brushes 51 to enter and exit the three sockets 33 corresponding to the three-pin plug on the socket panel 32 and perform deburring and grinding on the three sockets 33, and the two sleeves 50 on the concave seat B47 of each grinding mechanism 34 are reciprocatingly inserted into the two positioning columns 18 on the concave seat A16 of the corresponding positioning mechanism 5 and drive the corresponding brushes 51 to enter and exit the two sockets 33 corresponding to the two-pin plug on the socket panel 32 and perform deburring and grinding on the two sockets 33.

[0060] After the socket 33 on the socket panel 32 is polished, the motor D60 is stopped so that the small diameter arc surface of the cam 59 abuts against the pressure seat 54, and the two hydraulic cylinders 58 are started to drive the shell 57 and the structure on the shell 57 to move vertically upward and reset, so that the five sleeves 50 in each polishing mechanism 34 are disengaged from the five positioning columns 18 on the corresponding positioning mechanism 5.

[0061] Then, the motor A3 is started to drive the conveyor belt 4 to run, and the conveyor belt 4 drives all the polished socket panels 32 to move and finally automatically fall into the collection box.

[0062] Next, an equal number of socket panels 32 are installed on the conveyor belt 4 according to the above process and the polishing of the socket holes 33 on the socket panels 32 is finally completed.

[0063] To sum up, the beneficial effects of the present invention are as follows: the present invention can adjust the relative positions of the recess A16 and the protrusion A13 in the positioning mechanism 5 on the conveyor belt 4 according to the relative positions of the five sockets 33 on the five-hole socket panel 32, so that the three positioning columns 18 on the protrusion A13 correspond one-to-one to the three sockets 33 corresponding to the triangular plug on the socket panel 32, and the two positioning columns 18 on the recess A16 correspond one-to-one to the two sockets 33 corresponding to the two-pin plug on the socket panel 32, so that each positioning mechanism 5 on the conveyor belt 4 can position the five-hole socket panels 32 of different specifications through the five positioning columns 18 thereon, without the need for a special clamping structure, and the flexibility of clamping and positioning the socket panel 32 is better, and the efficiency of clamping and positioning the socket panel 32 is higher.

[0064] In the present invention, the grinding mechanism 34 on the pressure seat 54 automatically adjusts the relative positions of the corresponding protrusions B43 and recesses B47 through the optical sensor 48, so that the protrusions B43 and recesses B47 on the grinding mechanism 34 correspond one-to-one with the protrusions A13 and recesses A16 in the corresponding positioning mechanism 5 on the conveyor belt 4, and the bristles 51 on the five sleeves 50 on the grinding mechanism 34 grind the sockets 33 on the socket panel 32 where the positioning columns 18 on the protrusions B43 and recesses B47 are located, thereby realizing efficient grinding of the socket panels 32 in batches.

[0065] Compared with the traditional sandblasting and grinding technology, the present invention has the advantages of saving resources and high grinding efficiency. The present invention has the advantages of flexibility of manual grinding and high grinding efficiency at the same time.
