At the same time, a tension spring 44 is also fixedly installed between the rotating bar 42 and the workbench 6 for driving the support frame 15 to reset and rotate after the processing is completed.

[0028] The cleaning mechanism includes a first guide rod 29 fixedly arranged on the outer side of the arc plate 28, a sliding ring 30 is slidably sleeved on the outer wall of the first guide rod 29, and a plug 32 for limiting the sliding ring 30 is arranged at both ends of the first guide rod 29. It can prevent the sliding ring 30 from being separated from the first guide rod 29, and at the same time, a clearance groove matching the arc plate 28 is opened on one side of the sliding ring 30. When the clearance groove moves to one side of the arc plate 28, the sliding ring 30 cannot rotate. A third connecting strip 31 is fixedly installed on the outer wall of the sliding ring 30. The third connecting strip 31 is in an inverted L shape, and a cleaning block 33 matching the thread teeth is fixedly installed at the bottom. In order to limit the initial cleaning block 33, that is, when the sliding ring 30 is located at one end of the arc plate 28, a limiting member is also set on the top of the limiting plate 13, and the limiting member includes a rotating plate 34 rotatably arranged on the top of the limiting plate 13, a ball 37 is embedded in the top of the third connecting strip 31, and a groove 35 is provided at the bottom of the rotating plate 34 for use with the ball 37, and the sliding ring 30 can be transitioned to one side of the arc plate 28.

[0030] In order to realize the rotation of the rotating ring 8, a gear 26 is fixedly sleeved on the output end of the first motor 11, and a gear ring 25 meshing with the gear 26 is fixedly sleeved on the outer wall of the rotating ring 8 to drive the rotating ring 8 to rotate.

[0031] In order to support the transmission shaft 20 , a sleeve rod 38 is rotatably sleeved on the outer wall of the transmission shaft 20 , and two sliding seats 39 are slidably sleeved on the outer wall of the sleeve rod 38 . Both sliding seats 39 are fixedly connected to the arc plate 28 .

[0032] In the present application, first, the stud 1 is placed on the arc-shaped plate 28, and the reverse edge portion 3 is placed on the support frame 15, and the bolt head 2 is positioned using the positioning groove 43; Then the electric push rod 16 is started to retract, and the retraction of the electric push rod 16 can drive the extension rod 17 to approach the support seat 7. During the movement of the extension rod 17, the first connecting bar 18 can be driven to move. The movement of the first connecting bar 18 can drive the limit plate 13 to move through the spring 46. The movement of the limit plate 13 can drive the sliding rod 12 to slide in the support seat 7 and approach the stud 1 at the same time. When one side of the limit plate 13 contacts the stud 1, continuing to move can push the stud 1 to approach the support seat 7 until the bolt head 2 is pushed into the hexagonal hole 9, and the sliding rod 12 can drive the rotating bar 12 through the contact plate 36 during the movement. 42 rotates on the support bar 40, and during the rotation process, the positioning groove 43 can be driven away from the bolt head 2, and the tension spring 44 can be stretched through the bottom end until the other end of the stud 1 contacts the limit plate 13, and the bolt head 2 contacts the rotating ring 8, and then the cleaning block 33 is turned over, and the cleaning block 33 is stuck in the thread teeth at one end of the stud 1. During the flipping process of the cleaning block 33, the sliding ring 30 can be driven to rotate on the first guide rod 29 through the third connecting bar 31, and then the rotating plate 34 is rotated, so that the ball 37 at the top of the third connecting bar 31 is stuck in the groove 35 at the bottom of the rotating plate 34, and at this time, the cleaning block 33 can always be located in the thread teeth; The electric push rod 16 is retracted after being started again, and the first connecting bar 18 can continue to be driven to move through the extension rod 17. The first connecting bar 18 can move on the second guide rod 45 and compress the spring 46, and the transmission shaft 20 is pushed to move through the second motor 19. The movement of the transmission shaft 20 can drive the sleeve rod 38 to move in the two sliding seats 39, and can push the milling cutter 21 to approach the bolt head 2. At the same time, the second motor 19 is started to drive the transmission shaft 20 to rotate. The rotation of the transmission shaft 20 can drive the milling cutter 21 to rotate, and the first motor 11 is started. The first motor 11 can drive the rotating ring 8 to rotate through the meshing gear ring 25 and the gear 26. During the rotation of the rotating ring 8, the bolt head 2 can be driven to rotate through the hexagonal head 4 and the hexagonal hole 9, and the milling is carried out while rotating, and finally the buffer groove 5 is formed; At the same time, the bolt head 2 can use the thread teeth to drive the cleaning block 33 to move during the rotation process, and the movement of the cleaning block 33 can drive the third connecting strip 31 to move. When the third connecting strip 31 moves to one side of the arc plate 28, the ball 37 disengages from the groove 35. At this time, the sliding ring 30 can be limited by the arc plate 28, so that the cleaning block 33 will not flip. During the movement of the cleaning block 33, impurities in the thread teeth are cleaned. After the cleaning is completed, the first motor 11 is started to rotate in the reverse direction to drive the stud 1 to rotate in the reverse direction, and the cleaning block 33 can be driven to reset and move through the thread teeth; After the cleaning is completed, the electric push rod 16 is started to extend, and the first connecting bar 18 can be driven to move through the extension rod 17. During the movement of the first connecting bar 18, due to the reset effect of the spring 46, the limit plate 13 will not move. When the spring 46 is fully reset, it is extended again, which can drive the sliding rod 12 to move. During the movement of the sliding rod 12, the second connecting bar 23 can be driven to move. During the movement of the second connecting bar 23, the bolt head 2 in the hexagonal hole 9 can be pushed out through the push bar 10 until the electric push rod 16 is fully extended, and the rotating bar 42 can be reset and rotated under the action of the tension spring 44, and drive the support frame 15 to approach the bolt head 2 to support the bolt head 2, and then the rotating plate 34 and the third connecting bar 31 are rotated in turn, which can drive the cleaning block 33 away from the stud 1, and then the stud 1 is replaced and the processing continues.

[0033] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 11, the electric push rod 16 and the second motor 19 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
