The inner sliding sleeve is placed between the two groups of limiting wheels (10) which are rotatably arranged, the outer wall of the inner sliding sleeve is in contact with the two groups of limiting wheels (10) and the groove walls arranged on the grinding wheel (132), the shape of the groove is matched with that of the outer wall of the inner sliding sleeve, the inner sliding sleeve is in a vertical state, a controller arranged on the top plate (3) is electrically connected with each electric device, the controller is connected with an external power supply, the first double-shaft motor (81) is controlled to work through the controller, the threaded pipe (82) is in threaded connection with the threaded pipe (83), the threaded pipe (83) drives the two groups of clamping blocks (4) to move relatively, the clamping blocks move for a distance, the telescopic rod (92) with the inner cavity provided with the extrusion spring (93) and the two side ends of the inner sliding sleeve can bear extrusion, the pressure is in the range of the inner sliding sleeve, and therefore extrusion and fixation of the telescopic rod;

internal and external simultaneous polishing operation of inner sliding sleeve

After the inner sliding sleeve is fixed, the controller simultaneously controls the driving motor (51) and the second double-shaft motor (111) to work, the hollow pipe (91) can be driven to rotate through the meshed connection of the driving gear (52) of the driving motor (51) and the gear ring (53), so that the inner sliding sleeve which is extruded and fixed is driven to rotate quickly, the rotating rod (62), the grinding wheel (132) and the jacking rod (114) can be driven to rotate simultaneously through the second double-shaft motor (111), the rotating direction of the grinding wheel (132) is opposite to the rotating direction of the inner sliding sleeve, the grinding of the outer wall of the inner sliding sleeve can be accelerated, as the second double-shaft motor (111) drives the rotating rod (62) and the jacking rod (114) to rotate respectively through the first speed reducer (112) and the second speed reducer (113), the rotating rod and the jacking rod (114) can rotate slowly respectively, the rotating disk (61) is driven to rotate slowly through the rotating rod (62, so that the movable rod 64 drives the rectangular rod 72 to do linear reciprocating motion, the first grinding cylinder (74) can be inserted into the inner sliding sleeve, the inner sliding sleeve is matched with the rotating inner sliding sleeve to polish the inner sliding sleeve, after polishing, the inner sliding sleeve automatically returns to the original position, in the process, the jacking rod (114) rotates slowly, the roller (134) can be jacked up slowly through the convex block, so that the grinding wheel (132) moves upwards slowly, the moving distance is very small, the distance is the grinding thickness of the inner sliding sleeve, and the jacking rod (114) can be replaced and disassembled, the jacking rods (114) with different jacking amplitudes can be replaced to realize the polishing of the inner sliding sleeve in different degrees, when the first grinding barrel (74) makes a reciprocating motion, the controller controls each motor to stop working, the jacking rod (114) just rotates for one circle, and the roller (134) is contacted with the rod body of the jacking rod (114);

taking of inner sliding sleeve

In deepening the space between both sides telescopic link (92) with the finger, clip the inner sliding sleeve, but the first biax motor (81) of rethread controller control makes and presss from both sides tight piece (4) and resume the normal position, can take out the inner sliding sleeve.
