[0033] In order to facilitate the disassembly and assembly of the connector 4, the connector 4 includes a connecting cylinder 42 rotatably connected to the rotating groove 31, the cavity 41 is opened inside the connecting cylinder 42, and a plurality of mounting holes 43 are provided at the bottom of the connecting cylinder 42. The splicing body 6 is connected to the mounting holes 43. Figure 3 As shown in the figure, the splicing body 6 includes a compression cylinder 64 arranged at the bottom of the connecting cylinder 42, and the movable chamber 61 is arranged inside the compression cylinder 64, and a plurality of bolt columns 65 matching the mounting holes 43 are installed on the top of the compression cylinder 64. During installation, the bolt columns 65 are first rotated into the mounting holes 43, and the bolt columns 65 are threadedly connected to the mounting holes 43 so that the bolt columns 65 are fixed inside the mounting holes 43, thereby fixing the compression cylinder 64 at the bottom of the connecting cylinder 42.

[0034] In order to facilitate the connection between the output shaft 51 and the sliding tube 62, an electromagnetic ring 63 is provided inside the splicing body 6. Figure 6 , Attachment Figure 7 and attached Figure 8 As shown;

[0035] A movable cavity 61 is provided in the splicing body 6, and a sliding tube 62 is provided inside the movable cavity 61. The sliding tube 62 is outside the output shaft 51. A locking piece that engages with the inside of the cavity 41 is provided on the top of the sliding tube 62, and the sliding tube 62 is connected to a plug-in part that is plugged into the rotating part 9. An electromagnetic ring 63 is installed inside the movable cavity 41.

[0036] The output shaft 51 is provided with a limited strip groove 52, and the engaging member includes a locking ring body 66 connected to the upper part of the sliding tube 62, the locking ring body 66 is made of metal, and the inner side of the locking ring body 66 is provided with a plurality of sliders 67 matching the limited strip groove 52, and the top of the locking ring body 66 is connected with a locking block 68, and the locking block 68 is provided with a locking groove 69, and a plurality of electric rods 44 are installed on the inner wall of the cavity 41, and the electric rod 44 is provided with an arc block 45, and a retaining ring body 46 is installed on the inner wall of the cavity 41, and the retaining ring body 46 is provided with an arc groove 47 through which the arc block 45 passes. The plurality of arc blocks 45 are assembled into a prism, and the prism is adapted to the engaging groove 69.

[0037] At the starting position, the electromagnetic ring 63 is not energized, and the electromagnetic ring 63 has no suction force on the metal locking ring body 66. At this time, the electric rod 44 is controlled to start, so that the electric rod 44 extends, and the arc block 45 fixedly connected to the output end of the electric rod 44 passes through the arc slot 47. When the arc block 45 contacts the locking slot 69, because the arc block 45 is smaller than the locking slot 69, when the four arc blocks 45 are completely pushed open by the electric rod 44 to form a prism that matches the locking slot, the arc block 45 is just stuck in the locking slot 69. Because the outer part of the arc block 45 is larger than the locking slot 69, the arc block 45 will not deflect inside the locking slot 69. In this way, the locking ring body 66 outside the sliding sleeve 62 is locked in the locking groove 69 through the four arc blocks 45, and then the locking ring body 66 and the connecting tube 41 form a whole. After the motor 5 is driven, the connecting tube 41 is driven to rotate, so that the splicing body 6 and the mounting plate installed at the bottom of the connecting tube 41 are rotated.

[0038] In order to achieve grinding processing on different positions of different workpieces, different tools need to be replaced. A splicing body 6 is installed at the lower part of the connecting body 4, and a mounting plate 7 is installed at the bottom of the splicing body 6. Different tools 8 are installed on the mounting plate 7. A rotating component 9 for driving the tool 8 to rotate is installed at the lower part of the mounting plate 7.

[0039] The rotating component 9 includes a limit block 91 arranged in the limit cavity 71, and the limit block 91 passes through the mounting plate 7 and is connected to a gear plate 92. The mounting plate 7 is provided with a plurality of fixing holes 93, and fixing bolts 94 are installed inside the fixing holes 93. The fixing bolts 94 are connected to the mounting part of the tool 8, and the mounting part of the tool 8 is covered with a rotating gear 95, and the gear plate 92 is meshed with the rotating gear 95.

[0040] A rotating gear is sleeved on the mounting part of the tool 8, and a hole is opened on the mounting part of the tool 8. After the fixing bolt 94 is passed through the fixing hole 93, it is threadedly connected to the hole of the mounting part of the tool 8, and then the fixing bolt 94 is fixed at the position of the mounting disk 7 by a nut. After the motor 5 is driven, the engaged connecting tube 41 is driven to rotate, so that the mounting disk 7 is rotated, which is convenient for rotating the installed tool to the required position, so as to facilitate adjusting different tools to process the workpiece. When the workpiece is adjusted, the electromagnetic ring 63 is energized at this time, so that the electromagnetic ring 63 generates suction on the metal engaging ring body 66, and at the same time controls the electric rod 44, so that the arc block 45 and the engaging groove 69 at the output end of the electric rod 44 are disengaged, and under the suction of the electromagnetic ring 63, the engaging ring body 66 is easy to slide downward.

[0041] The bottom of the compression cylinder 64 is connected to the mounting plate 7 . A limiting cavity 71 is provided inside the mounting plate 7 , and the limiting cavity 71 is communicated with the moving cavity 61 .

[0042] The plug-in component includes a plug-in block 621 connected to the bottom of the sliding tube 62 , the plug-in block 621 is provided with a plurality of protrusions, the top of the limit block 91 is provided with a plurality of grooves that cooperate with the protrusions, and the plug-in block 621 is plugged into the limit block 91 .

[0043] A return spring 631 is provided between the locking ring body 66 and the electromagnetic ring 63 .

[0044] When the locking ring body 66 slides downward, the plug-in block 621 at the bottom of the sliding tube 62 is inserted into the groove of the limit block 91. At this time, the locking ring body 66 and the connecting tube 41 are disengaged, and the plug-in block 621 at the bottom of the sliding tube 62 is inserted and fixed. When the output shaft 51 rotates, the gear plate 92 at the bottom is driven to rotate, thereby rotating the rotating gear 95 meshing with the gear plate 92, thereby facilitating the grinding process of the workpiece by the tool 8.

[0045] A fixed plate 12 is installed on the outer side of the conveying platform 1, and two swing grooves 13 are respectively opened on both sides of the fixed plate 12. A swing shaft 14 is installed at the swing groove 13, and a railing 15 is connected to the outside of the swing shaft 14. A swing motor 16 is connected to the top of the swing shaft 14.

[0046] When the workpiece needs to be processed after forming, the workpiece is placed on the conveying platform 1 and transported by the conveying chain 11. When the workpiece is transported to the front end position of the railing 15, the swing motor 16 is controlled at this time. Under the action of the swing motor 16, the swing shaft 14 starts to rotate. When the railings 15 are just distributed, both railings 15 are in contact with the outer wall of the conveying platform 1. After the swing motor 16 starts to rotate, the railings 15 in the direction of the workpiece entering start to rotate and are horizontally distributed on the conveying platform 1, thereby blocking the subsequent workpieces. The workpiece is conveyed and polished at the same time. At the same time, the rear railings 15 are also horizontally distributed on the conveying platform 1, thereby avoiding the workpiece from being transported away before the processing is completed. When the workpiece is polished, the two railings 15 are rotated to the original position to facilitate the processing of the next workpiece. Through the processing of the six-axis robot arm and the processing of a single workpiece, the workpiece is polished without stopping to change the tool 8, thereby improving the processing efficiency of the workpiece parts.
