The first driving piece is used for providing the rotating speed of the workpiece spindle 3 at the welding station, and the second driving piece is used for synchronously providing the rotating speed of the workpiece spindle 3 at the rough grinding station, the fine grinding station and the fine polishing station.

In the process of machining, referring to fig. 1 and 3, at this time, because the engaging gear 11 is simultaneously matched with the driving gear 8 and the driven gear 5, the first driving part can transmit a power source to the workpiece spindle 3 at the welding station, and the connecting belt 15 can tightly link the workpiece spindles 3 at the rough grinding station, the fine grinding station and the fine polishing station, so that the second driving part can transmit power to the rough grinding station, the fine grinding station and the fine polishing station to realize linkage, and the rotating speeds are the same.

And in the process that the station switches, the utility model discloses an each structural design's importance has just embodied out:

firstly, before the station is switched, the retreating cylinder 6 needs to be acted, and due to the design of the full freedom degree of the universal joint 12, the connection part of the piston rod of the retreating cylinder 6 and the retreating rod 10 cannot generate the clamping phenomenon, after the retreating cylinder 6 drives the retreating rod 10 to overturn around the retreating rotating shaft 9, the engaging gear 11 can be separated from the driven gear 5 of the welding station, so that the turntable 2 can rotate, the clamping phenomenon cannot be generated due to the interference of the joint of the engaging gear 11 and the driven gear 5 at the position, and referring to fig. 2, the fig. 2 is compared with fig. 1, the engaging gear 11 and the driven gear 5 are already separated, and the engaging gear 11 cannot interfere with the rotation of the turntable 2.

Next, the turntable 2 rotates 1/4 circles, the workpiece originally at the fine polishing station is switched to the position of the welding station after the last process, the completely processed workpiece is unloaded, then a new workpiece is put on to wait for welding, the workpiece originally at the welding station is moved to the rough grinding station along with the workpiece spindle 3 because the welding is completed, the driven gear 5 of the workpiece spindle 3 is separated from the engaging gear 11, the driven pulley 4 is tightly connected with the connecting belt 15 after the workpiece is switched to the rough grinding station, the switching process can refer to fig. 4, the design of the tightening block 7 is very exquisite because the slack degree of the three driven pulleys 4 which are tightly connected with the connecting belt 15 because of the change of the positions during the switching process, in order to prevent the connecting belt 15 from falling off, the action of the tightening spring 17 is reflected, which can drive the tightening belt wheel 16 to push towards the outer surface of the connecting belt 15 at any moment, so as to realize the tight fit of the connecting belt 15 with the three driven belt wheels 4 at different positions all the time, and each time the station is switched, one of the three driven pulleys 4 is separated from the connecting belt 15 and then moved to a position waiting to be engaged with the engaging gear 11, while the driven pulley 4, which was separated from the connecting belt 15, is fitted to the connecting belt 15, the "one-off, one-off complementary fit" process also requires the pulley 16 to be tightened at all times to provide a tightening force to prevent the connecting belt 15 from being detached, after the station switching is completed, the position-withdrawing cylinder 6 moves the connecting gear 11 again, so that the connecting gear is matched with the driven gear 5 at the welding station to form the state of the position to be processed of the next group.

The design of the position relationship between the driving pulley 13 and the reversing pulley 14 is also very important, wherein the driving pulley 13, besides providing power, also has an important function of expanding the connecting belt 15 by combining the reversing pulley 14, defining a virtual surface where the main shafts of the two are located, and ensuring that the driven pulley 4 closest to the virtual surface is not attached to the connecting belt 15, so that the workpiece main shaft 3 at this position can be separated from the second driving member, and is defined mathematically: five points where the drive pulley 13, the reverse pulley 14, and the three driven pulleys 4 distant from the virtual surface are located form a virtual pentagon, and the other driven pulley 4 is inevitably inside the virtual pentagon.
