[0028] The fixing assembly 23 is disposed on the main assembly 21 and is used to position the parts.

[0029] In this embodiment, the upper ear seat 225 is driven to move by the output end of the cylinder 224. The upper ear seat 225 drives the limit frame 227 through the second support rod 226 and with the cooperation of the first support rod 223. The limit frame 227 drives the slider 214 to slide along the inside of the slide groove 213, so that the slider 214 drives the fixed component 23 to move, thereby achieving the simultaneous adjustment of the distance between each fixed component 23 and the axis of the turntable 212, so that the position of the fixed component 23 can be adjusted when different parts need to be processed.

[0030] Specifically, the adjusting component 22 further includes a guide groove 228 provided at the upper end of the limiting frame 227 , a guide pin 229 fixed at the upper end of the first support rod 223 , and the guide pin 229 is slidably installed in the guide groove 228 .

[0031] In this embodiment, when the second support rod 226 drives the first support rod 223 to rotate, the first support rod 223 drives the guide pin 229 to slide along the inside of the guide groove 228, so that the first support rod 223 cooperates with the second support rod 226 to drive the limit frame 227 to move horizontally.

[0032] Specifically, the middle portion of the first support rod 223 is pivotally connected to the middle portion of the second support rod 226 , and grooves are formed on the facing surfaces of the first support rod 223 and the second support rod 226 .

[0033] In this embodiment, when the second support rod 226 moves, it can drive the first support rod 223 to move, and avoid movement interference between the two.

[0034] Specifically, the fixing assembly 23 includes a base 231 fixed on the top of the slider 214, a slide rail 232 fixed on the top of the base 231, a first chuck 233 and a second chuck 234 slidably installed on both sides of the upper end of the slide rail 232, a guide rod 235 fixed between the two ends of the first chuck 233, and the guide rod 235 and the second chuck 234 are slidably installed, a pad 236 fixed in the middle of the guide rod 235, a motor 237 installed at one end of the top of the base 231, an eccentric block 238 installed at the output end of the motor 237, and the eccentric block 238 is located between the second chuck 234 and the pad 236.

[0035] In this embodiment, after the part is placed between the first chuck 233 and the second chuck 234, the eccentric block 238 is driven to rotate through the output end of the motor 237, so that the two ends of the eccentric block 238 away from the axis respectively push the second chuck 234 and the pad 236 to move, and at the same time, the pad 236 drives the first chuck 233 to move through the guide rod 235, so that the first chuck 233 cooperates with the second chuck 234 to fix the part between them.

[0037] In this embodiment, when the two ends of the eccentric block 238 away from the axis are separated from the second clamp 234 and the pad 236 respectively, the rebound pressure of the spring 239 pushes the first clamp 233 and the second clamp 234 at both ends to move in the opposite direction for reset, and releases the fixation of the parts between them.

[0038] Specifically, a grinding assembly 3 is installed at the rear end of the top of the grinder 1 , and a material picking assembly 5 and a material feeding assembly 4 are installed at the left and right ends of the top of the grinder 1 , respectively.
