[0027] See also Figure 1 The transmission mechanism 2 includes a transmission frame 201, and the transmission frame 201 is fixedly installed on the upper end of the base 1. A transmission cylinder 202 is rotatably installed on the upper end of the transmission frame 201 through a bearing. A conveyor belt 203 is wound on the outer wall of the transmission cylinder 202. The surface of the conveyor belt 203 is set as a rough non-slip surface so that the parts will not move when they are transported. A driven wheel 204 is fixedly installed on one end of the transmission cylinder 202, and a transmission belt 205 is wound on the outer wall of the driven wheel 204. A mobile motor 206 is fixedly installed on the upper end of the base 1 near the transmission belt 205.

The output end of the mobile motor 206 is fixedly installed with a driving wheel 207, and the end of the transmission belt 205 away from the driven wheel 204 is wound around the outer wall of the driving wheel 207. When the mobile motor 206 is started, the driving wheel 207 drives the driven wheel 204 to start rotating through the transmission belt 205, and the transmission cylinder 202 drives the conveyor belt 203 to start rotating, so that the parts can be placed on the surface of the conveyor belt 203 for transmission and grinding, which reduces the residence time of the parts and speeds up the processing efficiency of the part grinding.

[0028] See also Figures 1 to 5The fixing mechanism 3 includes a fixing rod 301, and the fixing rod 301 is fixedly welded on the inner wall of the mounting frame 101 near the transmission belt 205. A sliding frame 302 is slidably installed on the side end of the fixing rod 301. The distance between the fixing mechanisms 3 is adjusted by the sliding frame 302, so that it is more convenient to clamp parts of different sizes. A limiting plate 303 is fixedly installed on the lower end of the sliding frame 302. A slide rail 304 is installed on the upper end of the limiting plate 303 near the grinding mechanism 4 through a nut. A sliding block 305 is slidably installed on the upper end of the slide rail 304. A return spring 306 is fixedly welded between the sliding block 305 and the sliding frame 302.

[0029] See also Figures 1 to 5 The upper end of the sliding block 305 is rotatably installed with a rotating rod 307, and the upper end of the rotating rod 307 is fixedly installed with a fixing frame 308, and the upper end of the fixing frame 308 is rotatably installed with an extrusion rod 309, and the extrusion rod 309 is set in a "V" shape. When the part moves through the conveyor belt 203 and contacts the fixing frame 308, the part pushes the extrusion rod 309 to rotate, so that the extrusion rod 309 squeezes and fixes the part. A semicircular gear ring 310 is fixedly installed on the side end of the rotating rod 307, and a limiting block 311 is slidably installed on the lower end of the rotating rod 307, and the side end of the sliding block 305 close to the limiting block 311 is provided with a limiting groove 312 that fits with the limiting block 311, and a linkage block 316 is slidably installed in the limiting groove 312. When the limiting block 311 moves into the limiting groove 312, the limiting block 311 prevents the rotating rod 307 from rotating. When the limiting block 311 moves out of the limiting groove 312, the rotating rod 307 The movable rod 307 can rotate, and a limiting spring 313 is fixedly installed between the limit block 311 and the rotating rod 307.

A rack 315 is fixedly welded on the upper end of the stop block 314. When the rotating rod 307 moves to one end of the stop block 314, the stop block 314 pushes the limit block 311 to shrink, and the semicircular gear ring 310 provided on the rotating rod 307 is meshed and connected with the rack 315, so that when the sliding block 305 continues to move, the rack 315 causes the rotating rod 307 to start rotating, thereby taking out and throwing out the polished parts.

[0030] See also Figures 1 to 7The grinding mechanism 4 includes a grinding rope 401, and the grinding rope 401 is set to be a nylon rope in the prior art, which will not be described in detail here. A frosting ring 402 is sleeved on the outer wall of the grinding rope 401, and the frosting ring 402 is set to be a frosting cylinder formed by winding 1000-mesh sandpaper in the prior art, which is sleeved on the outer wall of the grinding rope 401, so that when the grinding rope 401 is bent, the frosting ring 402 follows the bending of the grinding rope 401 without wrinkles. A fixed ring 403 is fixedly installed at one end of the grinding rope 401, and the fixed ring 403 is rotatably sleeved on the side end of the mounting frame 101, and a clamping ring 404 is rotatably sleeved on the end of the mounting frame 101 away from the fixed ring 403, and the rotating clamping ring 404 makes the grinding rope 401 rotate more To make it more convenient, a fixed cylinder 405 is slidably installed on the inner wall of the clamping ring 404, a telescopic spring 406 is fixedly welded between the fixed cylinder 405 and the clamping ring 404, a spring sheet 407 is fixedly installed on the inner wall of the fixed cylinder 405, and an anti-sliding block 408 is fixedly installed on the end of the spring sheet 407 away from the fixed cylinder 405. When the grinding rope 401 needs to be fixed in the fixed cylinder 405, the grinding rope 401 is passed through the fixed cylinder 405, so that the grinding rope 401 pushes the anti-sliding block 408 to move and squeeze the spring sheet 407. The spring sheet 407 pushes the anti-sliding block 408 to squeeze the grinding rope 401. When the grinding rope 401 moves in the opposite direction, the anti-sliding block 408 blocks the movement of the grinding rope 401, making the installation and fixation of the grinding rope 401 more convenient.

[0031] See also Figures 1 to 7 A driving motor 409 is fixedly installed on the side end of the mounting frame 101 near the clamping ring 404. The driving motor 409 is a LEADSHINE open-loop single-axis stepping motor in the prior art, which will not be described in detail here.

The driving gear 410 and the rotating ring gear 411 are both configured as crown gears. When the grinding mechanism 4 needs to be used, the driving motor 409 is started, and the driving gear 410 meshes to drive the rotating ring gear 411 to start rotating, and the rotating ring gear 411 drives the clamping barrel to start rotating, and the fixed ring 403 drives the grinding rope 401 to start rotating, so that the grinding ring 402 grinds the parts.

[0032] See also Figures 1 to 8The regulating mechanism 5 includes a hydraulic box 501, and the hydraulic box 501 is fixedly welded to the upper end of the mounting frame 101, an air pump 502 is fixedly installed on the upper end of the hydraulic box 501, and a pressure gauge valve 503 is fixedly installed on the output end of the air pump 502. The pressure gauge valve 503 is a BLCH pneumatic valve. The air pressure regulating valve is of fixed size. The pressure gauge valve 503 provided at the output end of the air pump 502 controls the air pressure in the water pressure box 501 through the pressure gauge valve 503. A connecting telescopic tube 504 is fixedly installed at the lower end of the water pressure box 501. The end of the connecting telescopic tube 504 away from the water pressure box 501 is threadedly connected with a water-passing plate 505. A plurality of water outlet holes are provided at the lower end of the water-passing plate 505. The water-passing plate 505 is slidably installed on the inner wall of the mounting frame 101. A linkage rope 506 is fixedly installed at the upper end of the water-passing plate 505. A guide cylinder 507 is slidably installed on the inner wall of the mounting frame 101 close to the linkage rope 506. The guide cylinder slidably installed on the mounting frame 101 When 507 processes parts of different heights, it is more convenient to adjust the original height of the water-passing plate 505. A guide wheel 508 is rotatably sleeved on the outer wall of the guide cylinder 507, and the linkage rope 506 is wound on the outer wall of the guide wheel 508. The moving direction of the linkage rope 506 is changed by the guide wheel 508, and one end of the linkage rope 506 away from the water-passing plate 505 is fixedly installed on the upper end of the sliding block 305. When the part drives the sliding block 305 to move, the sliding block 305 drives the linkage rope 506 to start moving, so that the water-passing plate 505 starts to move downward. When the edge of the part moves to just below the polishing rope 401, the polishing rope 401 just contacts the surface of the part.

[0033] See also Figures 1 to 8 The lower end of the water-passing plate 505 near the water outlet is fixedly welded with a hydraulic cylinder 509, and the inner wall of the hydraulic cylinder 509 is slidably installed with a piston ring 510. After the liquid in the hydraulic box 501 enters the hydraulic cylinder 509, due to the flow characteristics of water, the pressure received by multiple piston rings 510 is kept consistent. The lower end of the piston ring 510 is fixed with a hydraulic rod 511 by a nut. The processing force of the grinding rope 401 is controlled by the air pressure and the gravity of the liquid itself. The force of the hydraulic rod 511 is the weight of the water plus the air pressure, and its calculation formula is: F = (P × S) + (ρghS) Where P represents pressure, S represents the area of ​​water affected by air pressure, ρ represents the density of water, g represents the acceleration of gravity, h represents the height of the water column, and S represents the area affected by force.

[0034] A semicircle 512 is fixedly welded to the lower end of the hydraulic rod 511, and a plurality of rollers 513 are installed in an array on the inner wall of the semicircle 512, and the rollers 513 are all fitted on the outer wall of the frosted ring 402, so as to avoid friction between the frosted ring 402 and the semi-cylinder, which may cause damage to the semi-cylinder.

[0035] The working principle of the present invention is: when it is necessary to grind the uneven steel parts, the parts are placed on the conveyor belt 203, the moving motor 206 is started, the driven wheel 204 drives the driving wheel 207 to start rotating through the transmission belt 205, the rotating drum rotates to drive the conveyor belt 203 to start moving, and when the parts move to one side of the fixed frame 308, the movement of the parts pushes the extrusion rod 309 to start rotating, so that the extrusion rod 309 starts to rotate, and the extrusion rod 309 and the fixed frame 308 squeeze the parts, thereby squeezing and fixing the parts to prevent the parts from moving during the grinding process; After the parts are fixed, the conveyor belt 203 continues to move, and the parts continue to move under the action of friction, and the movement of the parts drives the sliding block 305 to start moving. When the sliding block 305 moves, the linkage rope 506 starts to move, and the reset spring 306 starts to be stretched. The movement of the linkage rope 506 causes the water-passing plate 505 to start moving downward, so that when the edge of the part moves to the bottom of the grinding rope 401, the grinding ring 402 contacts the part, so that the polished part is more complete. When the sanding ring 402 contacts the part, the air pump 502 starts to work and starts to inflate the hydraulic box 501, so that the air pressure in the hydraulic box 501 starts to increase, and the force of the liquid in the hydraulic cylinder 509 pushing the hydraulic rod 511 downward to squeeze the part starts to increase, and the semi-circle 512 pushes the sanding rope 401 to bend and fit the uneven surface of the part, so that the uneven surface of the mechanical part can be sanded; At the same time, due to the flow characteristics of the liquid, the driving forces of the multiple hydraulic rods 511 are the same, so that the grinding ring 402 set on the outer wall of the grinding rope 401 squeezes the surface of the mechanical parts with the same force, and the driving motor 409 is started, so that the active gear 410 drives the driven gear ring to start rotating, and the clamping ring 404 drives the fixed cylinder 405 to start rotating, so that the grinding rope 401 starts to rotate, and the grinding ring 402 grinds the uneven surface of the mechanical parts with uniform force, thereby making it more convenient to grind the uneven parts.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
