[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a technical solution: comprising a frame assembly 1, wherein a grinding assembly 2 is arranged at the bottom of the frame assembly 1, a friction assembly 3 is fixedly installed at the top of the frame assembly 1, the frame assembly 1 comprises a bottom plate 101 and a support rod 102, a plurality of support rods 102 are evenly fixedly installed on the annular edge of the top surface of the bottom plate 101, a top ring 103 is fixedly installed on the top of the plurality of support rods 102, and a gear ring 104 is fixedly embedded at the bottom of the annular inner ring of the top ring 103;

[0025] The grinding assembly 2 includes a rotating motor 201 and a rotating head 202. The rotating head 202 is fixedly installed on the top of the output shaft of the rotating motor 201. A plurality of support plates 203 are fixedly installed on the side of the rotating head 202. A cylinder 204 is fixedly installed on the top of the support plate 203 away from the rotating head 202. A gear 205 is rotatably installed on the top of the cylinder 204. A docking plug 206 is fixedly installed on the top of the gear 205.

[0026] The friction assembly 3 includes a vertical plate 301 and a polishing arc plate 302, and the polishing arc plate 302 is fixedly installed on the front side of the vertical plate 301;

[0027] The rotating motor 201 is fixedly mounted at the center of the top surface of the base plate 101, the gear 205 is meshedly connected with the gear ring 104, and the vertical plate 301 is fixedly mounted at the edge of one side of the top surface of the top ring 103. Since the gear 205 is meshedly connected with the gear ring 104, the gear 205 will rotate itself when it revolves, and its rotation can drive the bolt to rotate.

[0028] In this embodiment, a vertical groove is provided in the middle of the front side of the vertical plate 301 , a screw rod 303 is rotatably installed in the vertical groove, and an L-shaped lifting plate 304 is threadedly sleeved on the screw rod 303 .

[0029] At the same time, a top cover 305 is fixedly installed on the top of the front side of the L-shaped lifting plate 304, and the top cover 305 is located directly above the polishing arc plate 302. When the top cover 305 is covered directly above the polishing arc plate 302, the distance between the bottom surface of the top cover 305 and the top surface of the bolt is less than the depth of the polygonal slot.

[0030] The bottom of the outer side surface of the polished arc plate 302 is fixedly connected to the top of the inner circle of the top ring 103, making the structure more stable.

[0031] A plurality of support plates 203 are distributed in a ring shape on the side of the rotating head 202, and multiple groups of bolts can be simultaneously rotated.

[0032] The top surface of the docking plug 206 is provided with a polygonal slot to facilitate the installation of the bolt.

[0033] When in use, the bolt to be deburred is taken out, and after taking it out, the bolt is inserted into the friction component 3 through the opening provided on the front side of the grinding arc plate 302, and then the hexagonal head of the bolt is aligned with the polygonal slot provided on the top surface of the docking plug 206 and the hexagonal head is inserted into the polygonal slot. After insertion, the rotating head 202 is driven to rotate manually or by rotating the motor 201. The rotation of the rotating head 202 can drive the six support plates 203 and the cylinder 204 fixedly installed on the support plate 203 to rotate, and the rotation of the cylinder 204 can drive the gear 205 rotatably installed thereon and the docking plug 206 fixedly installed on the top of the gear 205 to rotate. The screw rod 303 is rotated at this time. The rotation of the screw rod 303 can make the L-shaped lifting plate 304 threaded thereon rise and fall in the vertical groove. By controlling the L-shaped lifting plate 304 to descend, the top cover 305 can be driven to descend. The top cover 305 is covered on the top surface of the grinding arc plate 302. The top cover 305 can prevent the bolts from detaching from the top surface of the docking plug 206 during the process of grinding and removing burrs. After installing multiple bolts to be ground and deburred, the rotating motor 201 is started. The rotating motor 201 The cylinder 204 is driven to revolve around the center point of the rotating head 202, and when the cylinder 204 revolves, it can drive each gear 205 and the docking plug 206 fixedly installed on the top surface of the gear 205 to revolve, and the revolution of the docking plug 206 can drive the bolt plugged thereon to revolve, and the revolution of the bolt can drive its threaded section to contact the surface of the grinding arc plate 302, and the surface of the grinding arc plate 302 is bonded with sandpaper or a grinding brush and other grinding parts, and the position of the grinding arc plate 302 will just contact the surface of the normal bolt threaded section. Therefore, when the bolt revolves, the burrs on its surface will contact the sandpaper or grinding brush bonded to the surface of the grinding arc plate 302. The bolt 204 can be brought into contact with a grinding brush or other grinding parts, thereby grinding and removing burrs on the bolt surface, while revolution can only grind part of the bolt surface, so the bolt needs to rotate on its own for comprehensive grinding. When the cylinder 204 revolves, the gear 205 rotatably installed on its top will also revolve. Since the gear 205 is meshed and connected with the gear ring 104, the gear 205 will also rotate on its own when it revolves, and its rotation can drive the bolt to rotate on its own, thereby completing the processing of removing burrs from the threaded section of the bolt. After the processing is completed, it is only necessary to lift the top cover 305 and lift the bolt upward, which makes loading and unloading more convenient and quick.

[0034] To sum up, the bolt burr removal device controls the bolt to revolve around a point while rotating itself, so that the threaded segment can be fully polished and deburred, and multiple bolts can be deburred at one time, which effectively improves the processing efficiency and is more practical. At the same time, the steps of taking out and putting in the bolts are also relatively simple, which effectively improves the efficiency of loading and unloading.
