The polishing unit comprises a mandrel 8 assembling and disassembling mechanism, a polishing mechanism and a manipulator, wherein the mandrel 8 assembling and disassembling mechanism is used for inserting the mandrel 8 into an inner hole of the output shaft 10 or removing the mandrel 8 inserted into the output shaft 10, a side cross-sectional view of the output shaft 10 is shown in fig. 8, the output shaft 10 is provided with a large-caliber end 101 and a small-caliber end 102, and the outer periphery of the output shaft 10 is polished to be the outer peripheral side of the large-caliber end 101. The grinding mechanism drives the output shaft 10 to rotate through the rotating mandrel 8 and grinds the periphery of the rotating output shaft 10, and the manipulator is used for transferring the output shaft 10 between the mandrel 8 loading and unloading mechanism and the grinding mechanism;

the loading and unloading groove comprises two side groove walls 11, an avoidance port 12 is respectively arranged on the two side groove walls 11, a channel 13 is formed between the two side groove walls 11, the width of the channel 13 is larger than the axial length of the output shaft 10 and smaller than the axial length of the mandrel 8, a finished product outlet which corresponds to the avoidance port 12 and is used for dropping the output shaft 10 is arranged at the bottom of the loading and unloading groove, and a finished product conveying channel 5 or a finished product collecting box which is communicated with the finished product outlet is arranged at the finished product outlet;
and a pushing mechanism corresponding to the avoidance opening 12 on the side groove wall 11 is arranged on one side of the loading and unloading groove, and is used for inserting the mandrel 8 into the output shaft 10 or removing the mandrel 8 from the output shaft 10 as shown in figures 1 and 2. The pushing mechanism comprises a pushing block driving mechanism 21, a pushing block 22, a clamping structure 23 and a clamping driving mechanism 24, the pushing block driving mechanism 21 drives the pushing block 22 to move in the direction close to and far away from the loading and unloading groove, the clamping structure 23 is arranged on one side, facing the avoidance port 12, of the pushing block 22, and the clamping structure 23 is driven by a clamping driver to clamp or loosen the mandrel 8. In this embodiment, the pushing block driving mechanism 21 and the clamping driving mechanism 24 are both telescopic cylinders, the clamping structure 23 includes a left clamping block and a right clamping block, the right clamping block is welded and fixed on the pushing block 22, and the left clamping block is fixed on a telescopic rod of the telescopic cylinder. Further, in order to prevent the push block 22 from deviating in direction when moving closer to and away from the loading and unloading slot, a guide rod for guiding the push block 22 may be further provided;
as further shown in fig. 1, a stop means is provided on the other side of the loading and unloading slot, which stop means corresponds to the relief opening 12 in the side slot wall 11 and provides a stop for the insertion of the spindle 8 into the output shaft 10, thereby unifying the insertion position of the spindle 8. The stopping mechanism comprises a stopping base 31 and a top column 32 fixedly arranged on one side of the stopping base 31 facing the avoidance port 12;
and the moving base is arranged on the moving base which is driven by a base driving mechanism (in the embodiment, the base driving mechanism is a telescopic cylinder) to enter and exit the loading and unloading groove from one end of the channel 13, and the moving base is used for intermittently transferring the output shaft 10 which is uniformly oriented and has the same axial direction with the width direction of the channel 13 (the width direction of the channel 13 is also the inserting direction of the mandrel 8) into the loading and unloading groove so as to insert the mandrel 8.

Only when the movable base moves to the receiving position where the receiving groove 42 corresponds to the feed opening 51, the output shaft 10 at the feed opening 51 can fall from the feed opening 51 to the receiving groove 42, and the abutting surfaces 41 are all abutted against the feed opening 51 except the receiving position, so that the output shaft 10 cannot fall from the feed opening 51. When the movable base enters and exits the loading and unloading groove, the two groove walls 11 and the bottom of the loading and unloading groove can be used as guide surfaces for the movement of the movable base, so that the moving stability of the movable base is improved;
the other end of the corresponding channel 13 is provided with a limiting mechanism for fixing the output shaft 10 which is sent to the loading and unloading groove through the movable base. As shown in fig. 1 and 4, the limiting mechanism includes a telescopic driving mechanism 61 and a limiting block 62 disposed at a telescopic end of the telescopic driving mechanism 61, and the limiting block 62 has an arc-shaped shaft clamping surface 63 for fitting to the circumferential side of the output shaft 10. In this embodiment, the telescopic driving mechanism 61 is a telescopic cylinder, and the limiting block 62 extends out and abuts against the output shaft 10 under the driving of the telescopic cylinder, so as to limit and fix the output shaft 10, and facilitate the insertion of the mandrel 8 on the output shaft 10;
the mechanical hands are two in number, one mechanical hand is used for clamping the output shaft 10 from the station, and the other mechanical hand is used for placing the output shaft 10 on the station. For the sake of convenience of distinction, the first robot 71 and the second robot 72 are referred to as "first robot" and "second robot", respectively. According to the general knowledge in the technical field, the manipulators are arranged on the shifting device, for example, as shown in fig. 5, a first manipulator 71 is arranged on a vertically telescopic cylinder, a second manipulator 72 is arranged on a vertically telescopic cylinder with a certain inclination angle, so that the first manipulator 71 moves vertically up and down, the second manipulator 72 moves obliquely up and down, and the two manipulators are ensured not to interfere with each other, and the two telescopic cylinders are arranged on linear motor guide rails and move synchronously;

In this embodiment, as shown in fig. 6, the mandrel 8 includes a rod 81 and a poke rod 82 vertically disposed on the rod 81 and close to one end of the rod 81, and the rotation of the mandrel 8 is realized by pushing the poke rod 82. It should be noted that the mandrel 8 is driven to rotate by the rotation of the positioning column through the clamping connection of the special-shaped groove and the positioning column, and the relative fixed relation between the mandrel 8 and the positioning column needs to be ensured. However, in the present embodiment, the rotation of the spindle 8 is realized by pushing the poke rod 82, and there is no need to rely on the rotation of the positioning column, so that the positioning column abuts against the spindle 8 in a rotatable manner. For example, the end slots at the two ends of the rod 81 are tapered holes matched with the tapered positioning columns, so that the rod 81 and the positioning columns can rotate relatively;
as shown in fig. 1 and 7, the polishing mechanism includes positioning pillars for abutting and positioning two ends of the rod 81, a rotating push rod 93 for pushing the poke rod 82 to rotate circumferentially around the rod 81, a polisher for polishing the periphery of the output shaft 10, and a measuring instrument 95 for measuring the size of the output shaft 10 after polishing, wherein at least one of the positioning pillars can be extended and retracted in the abutting direction.
