The movable end of the driving motor 303 is connected to a T-shaped shaft 304. The end of the T-shaped shaft 304 away from the driving motor 303 is fixedly connected to a rotating frame 305. The T-shaped shaft 304 is movably clamped inside the limit plate 302. The driving motor 303 is connected to the T-shaped shaft 304 through the T-shaped shaft 304. 4 forms a rotating structure with the rotating frame 305. A plurality of slots are evenly opened on the surface of the rotating frame 305. A positioning plate 306 is provided inside the slots. A honing bar 307 passes through the positioning plate 306. A driven gear 308 is fixed to the surface of the honing bar 307. A hexagonal nut 309 is threadedly sleeved on the outer surface of the honing bar 307. Furthermore, the honing bar 307 and the positioning plate 306 form a detachable structure through the hexagonal nut 309. The rotating frame 305 and the positioning plate 306 are fixedly connected. The present invention effectively drives the T-shaped shaft 304 to rotate by driving the motor 303, thereby driving the rotation of the rotating frame 305, so as to facilitate the rapid replacement of the honing stick 307 on the surface of the rotating frame 305, thereby reducing the non-honing time in the processing process, improving productivity, and reducing production costs. The honing stick 307 can be separated from the positioning plate 306 by removing the hexagonal nut 309, so as to facilitate the subsequent removal of the worn honing stick 307.

[0028] It is noteworthy that the adjustment mechanism 2 includes a high-speed motor 201, which is mounted on top of the fixed bracket 1. The movable end of the high-speed motor 201 is connected to a screw rod 202, which is sheathed with a threaded block 203. The present invention effectively drives the screw rod 202 to rotate by the high-speed motor 201, thereby driving the threaded block 203 to move up and down on the surface of the screw rod 202, achieving height adjustment. This also facilitates the vertical movement of the honing stick 307 within the slot to be honed in the workpiece, thereby improving the honing effect.

[0029] It is worth noting that the driving assembly 4 includes an L-shaped frame 401, which is fixed to the rear surface of the limit plate 302, and an electric push rod 402 is connected to the surface of the L-shaped frame 401, and the movable end of the electric push rod 402 is connected to a support plate 403, and the end of the support plate 403 away from the electric push rod 402 is fixedly connected to a clamping frame 404, and a micro motor 405 is fixed inside the clamping frame 404, and the movable end of the micro motor 405 is connected to a rotating shaft 406, wherein a sliding groove for the translation of the rotating shaft 406 is opened on the surface of the L-shaped frame 401, and the support plate 403 is movably fitted to the surface of the L-shaped frame 401, and a driving gear 407 is fixed to the bottom of the rotating shaft 406, further, the driving gear 407 is meshed with the driven gear 308, and the driving gear 407 forms a meshing transmission structure with the driven gear 308 through the micro motor 405, the rotating shaft 406 and the driven gear 308. When the honing stick 307 needs to be replaced in the present invention, the electric push rod 402 drives the support plate 403 and the bracket 404 to move backward, thereby causing the micro motor 405, the rotating shaft 406 and the driving gear 407 to move backward. At this time, the driving gear 407 is separated from the currently engaged driven gear 308. After the honing stick 307 is replaced, the electric push rod 402 drives the support plate 403 and the bracket 404 to move forward, thereby causing the micro motor 405, the rotating shaft 406 and the driving gear 407 to move forward.

[0030] Working principle: The manipulator is installed on the workbench of the honing machine through the fixing bracket 1 and the fasteners.

At this time, the driving gear 407 is separated from the currently engaged driven gear 308. Then, the driving motor 303 drives the T-shaped shaft 304 to rotate, thereby driving the rotating rack 305 to rotate, and the honing bar 307 on the surface of the rotating rack 305 is quickly replaced. After the honing bar 307 is replaced, the electric push rod 402 drives the support plate 403 and the bracket 404 to move forward, thereby The micro motor 405, the rotating shaft 406 and the driving gear 407 move forward. At this time, the driving gear 407 is engaged with the replaced driven gear 308. Then, the micro motor 405 is started. The micro motor 405 drives the rotating shaft 406 and the driving gear 407 to rotate, thereby rotating the driven gear 308, and further rotating the honing stick 307, thereby realizing the honing of the workpiece slot by the honing stick 307. At the same time, the high-speed motor 201 drives the screw rod 202 to rotate, thereby driving the threaded block 203 to move up and down on the surface of the screw rod 202, realizing the height position adjustment, and at the same time, the honing stick 307 moves up and down inside the slot of the workpiece to be honed, thereby improving the honing effect.
