[0020] Furthermore, the first guide rail 107 is fixed to the side wall of the mounting plate 102; the first slider 108 is adapted to slide and connect with the first guide rail 107, and the top of the slider is fixedly connected to the support 109; the side of the support is provided with a vertical mounting surface for fixing the second guide rail 110, and the second slider 111 is adapted to slide and connect with the second guide rail 110 to ensure the lifting and lowering of the limit seat 106, thereby realizing height adjustment and adapting to the bearing requirements of different specifications of housings; the output shaft end of the second cylinder 112 is hinged to the side of the first slider 108, which can drive the first slider to move laterally along the first guide rail to realize the pushing of the housing to the clamping assembly.

[0021] Preferably, the first cylinder 202 is fixed to the top of the processing table 201; the cylinder output shaft extends and retracts in the horizontal direction, driving the clamping blocks 205 to open and close via the connecting rod 206; the rotary table 203 is fixed to the end of the first cylinder 202; the mounting base 204 is rotatably mounted on the top of the rotary table 203; the surface of the mounting base is evenly provided with sliding grooves for mounting the clamping blocks 205 and restricting their sliding direction; the clamping blocks 205 are evenly distributed and slidably connected in the sliding grooves of the mounting base 204; one end of the connecting rod 206 is hinged to the side of the clamping block 205 by a pin, and the other end is hinged to the top of the rotary table 203 by a pin; the connecting rod, the clamping blocks, and the rotary table form a triangular stable structure, which can drive all the clamping blocks to move radially synchronously when the output shaft of the first cylinder 202 extends and retracts, thereby achieving clamping of housings of different diameters.

[0022] It should be noted that the support column 301 is vertically inserted into the end of the base 101, and the connecting plate 302 is fixed to the top of the support column 301; the rotary motor 303 is fixed to the bottom of the connecting plate; the polishing disc 304 is rotatably mounted on the end of the output shaft of the rotary motor 303; the surface of the polishing disc can be replaced with different sandpapers to improve the smoothness according to the polishing requirements, and polishing is achieved by rotating and rubbing against the surface of the housing; the hydraulic cylinder 305 is fixed to the end of the connecting plate 302; the end of the output shaft of the hydraulic cylinder is hinged to the side wall of the rotary motor 303, which can drive the rotary motor to rise and fall vertically along the bottom of the connecting plate, adjust the contact pressure between the polishing disc 304 and the housing, and avoid excessive pressure that could cause the surface of the housing to dent.

[0023] In use, the operator places the valve housings 105 to be polished one by one into the conveyor track 104. The housings slide down the inclined track, and the frontmost housing falls into the groove of the limiting seat 106. The second cylinder 112 is activated, and the output shaft extends to push the first slider 108 to move laterally along the first guide rail 107 toward the processing table 201, causing the limiting seat 106 and the housing to move synchronously. At the same time, the second slider 111 rises along the second guide rail 110, raising the housing to a height concentric with the clamping block 205 of the clamping component. When the housing moves to the preset position between the clamping blocks 205, the second cylinder 112 stops, completing the loading and positioning of the housing. The first cylinder 202 is activated, the output shaft retracts and drives the clamping block 205 to retract radially along the sliding groove of the mounting seat 204 via the connecting rod 206; as the cylinder continues to retract, the clamping force gradually increases, fixing the housing; the limiting seat 106 is reset under the action of the second cylinder 112 and the second slider 111, returning to the lower end of the conveying track 104, waiting for the next feeding; The rotary motor 303 starts, driving the polishing disc to rotate; at the same time, the lifting hydraulic cylinder 305 starts, and the output shaft slowly extends, pushing the rotary motor to descend along the bottom of the connecting plate 302, so that the polishing disc 304 gradually contacts the surface of the valve body 105; the rotary table 203 starts, driving the mounting base 204 and the clamped housing to rotate at a constant speed, so that the outer surface of the housing is in uniform contact with the polishing disc 304; the polishing disc removes burrs, oxide scale and other defects from the surface of the housing through friction, thus completing the entire polishing process.

[0024] In summary, the feeding component 100 achieves automatic feeding by tilting the track and pushing the limit seat 106 with the bottom cylinder, eliminating the need for manual handling and positioning. With the cooperation of the clamping and polishing components, the polishing time of the valve body 105 is shortened, efficiency is improved, and the needs of mass production are met. The clamping component 200 adopts a synchronous radial movement design of the clamping block 205 to avoid surface scratches caused by the displacement of the housing during polishing. It does not require the replacement of the clamps and has strong versatility.
