The working principle of the invention is as follows:

in practical use, the polishing device is firstly communicated with an external power supply, a pipe to be polished is put into the material box 3, meanwhile, the device is adjusted to an initial state, namely, the inclined planes on the two sides of the movable plate 30 are respectively attached to the inclined plane on one side of the fixed plate 25 at the corresponding position, and no extrusion is generated between the two, at the moment, the pipe channel 35 on the upper plate 34 and the lower plate 33 is just arranged in a staggered way with the discharge port part of the material box 3, so that the pipe to be polished in the material box 3 is prevented from falling, the partial extrusion is generated between the inclined plane at the top of the push block 10 and the inclined plane at the bottom end of the movable block 6, then, the motor 20 does not work, the piston rod at the end part of the cylinder 18 is controlled by an external controller to retract, so that the push plate assembly 19 is driven to move to one side far away from the transverse block 4, in the process, the movable plate 30 can move to one side close to the cylinder 18 along with the middle plate 191, therefore, the inclined surfaces on the two sides of the movable plate 30 are used for extruding the inclined surface on one side of the fixed plate 25 at the corresponding position, so that the two cross blocks 4 move back to back, and the second spring 28 is extruded along the direction of the traction rod 27 at the corresponding position, at the same time, one end of the driving roller 21 and the grinding roller 22, which are provided with the cross-shaped lug 24, are separated from the cross-shaped groove 23 on the swing arm 13 at the corresponding position, and simultaneously, along with the separation of the inclined surfaces of the contact between the push block 10 and the movable block 6, the bottom ends of the two swing arms 13 at the corresponding positions move in opposite directions under the restoring force of the first spring 16, and the two swing arms 13 rotate back to back with the guide rod 17 as a central axis, so that the upper plate 34 and the lower plate 33 at the corresponding positions are driven to move in opposite directions by the hook plate 31 outside the swing arms 13, at the moment (taking the attached drawing 1 of the specification as a reference), the upper plate 34 moves to the right and the lower plate 33 moves in phase with the left phase, the pipe channel 35 formed on the upper plate 34 just allows a pipe to be polished stored in the bin 3 to pass through one pipe, the pipe channel 35 on the lower plate 33 is staggered with the feed opening of the bin 3, the pipe to be polished passing through the pipe channel 35 on the upper plate 34 falls into a cavity formed between the upper plate 34 and the lower plate 33 for temporary depositing, then, the piston rod at the end of the control cylinder 18 pushes the push plate assembly 19 to move right and drives the push block 10 and the movable plate 30 to move right and synchronously, at this time, the push block 10 moves right and pushes the movable block 6 to move vertically and upwards along the dovetail groove 8 direction, so that the two swing arms 13 rotate oppositely by taking the guide rod 17 as a central shaft, meanwhile, the hook plate 31 on the swing arm 13 deflects synchronously in the rotating process, so as to drive the upper plate 34 to move left and the lower plate 33 moves right, wherein the left movement of the upper plate 34 can make the pipe channel 35 formed on the upper plate 34 just stagger with the feed opening of the bin 3 and block the pipe to continue to be polished to fall down The through groove on the lower plate 33 is overlapped with the feed opening of the material box 3 when the lower plate 33 moves rightwards, so that the pipe to be polished temporarily stored in the cavity formed between the upper plate 34 and the lower plate 33 falls onto the rollers 12 at the tops of the two fixed seats 11 through the pipe passage 35 to be supported, and the pipe to be polished temporarily stored in the cavity formed between the upper plate 34 and the lower plate 33 falls, the polishing roller 22 and the cross-shaped projection 24 at the end part of the driving roller 21 are inserted into the cross-shaped groove 23, while the inclined planes at the two sides of the movable plate 30 are not extruded with the inclined plane at one side of the fixed plate 25 at the corresponding position respectively, and the piston rod at the end part of the air cylinder 18 is used for pushing the push plate assembly 19 to move rightwards, so as to drive the push block 10 and the inclined planes at the opposite sides of the movable block 6 to be extruded with each other, so that the movable block 6 vertically moves upwards along the direction of the dovetail groove one 8, and further the inclined planes at the two sides of the movable block 6 are used for extruding the rollers 12 at the bottoms of the two swing arms 13 at the corresponding position, the two swing arms 13 are made to continue to rotate in opposite directions by taking the guide rod 17 as a central axis, so as to clamp the pipe to be polished by utilizing the roller 12, the driving roller 21 and the polishing roller 22 on the top of the fixed seat 11, after the pipe to be polished is clamped, the two motors 20 are controlled to work simultaneously by an external controller so as to drive the driving roller 21 to drive the pipe to be polished to rotate, the polishing roller 22 is driven to polish the outer peripheral surface of the pipe to be polished, after the pipe to be polished is polished, the two motors 20 are turned off, then the piston rod at the end part of the cylinder 18 is controlled to drive the push plate assembly 19 to move to the left, and the piston rod at the end part of the cylinder 18 is controlled to drive the push plate assembly 19 to move to the left, so that the two transverse blocks 4 move back to each other by utilizing the extrusion generated between the inclined planes at the two sides of the movable plate 30 and the inclined plane at the side of the fixed plate 25 at the corresponding position, on the one hand, the polished pipe fittings can fall down, and the pipe fittings are conveyed to the next process along the material guide table 39 on the fixing plate 25, on the other hand, the upper plate 34 moves to the right and the lower plate 33 moves to the left, the pipe fitting channel 35 arranged on the upper plate 34 just allows the pipe fittings to be polished stored in the material box 3 to pass through one, the pipe fitting channel 35 on the lower plate 33 is staggered with the discharge port of the material box 3, the pipe fittings to be polished, which penetrate through the pipe fitting channel 35 on the upper plate 34, fall into a cavity formed between the upper plate 34 and the lower plate 33 for temporary depositing, the process is repeated in this way, the automatic loading, unloading and clamping and polishing work of the pipe fittings can be completed, the manual intervention is less, and the processing efficiency is greatly improved.
