A telescopic cylinder is connected to each side of the first platform 2011, allowing it to reciprocate towards the fixed mechanism 1 under the drive of the cylinders. The second platform 2012 is slidably connected to the upper surface of the first platform 2011 via a slide rail, which is also aligned with the axis of the flat drive roller 101. The crank connecting rod mechanism 2013 is located on the first platform 2011 and arranged parallel to the horizontal right side of the second platform 2012. The connecting rod of the crank connecting rod mechanism 2013 is rotatably connected to the second platform 2012, enabling it to drive the second platform 2012 to reciprocate along the slide rail parallel to the axis of the drive roller 101.

[0034] The two ends of the grinding roller 202 are connected to the second platform 2012 through the lugs. It is horizontally set on the side of the second platform 2012 near the fixing mechanism 1. The roller body of the grinding roller 202 is suspended on the outer edge of the second platform and is parallel to the axis of the drive roller 101.

[0035] The grinding motor 203 is fixedly mounted on the second platform 2012, located to the left of the grinding roller 202. The output end of the grinding motor 203 is rotatably connected to the input end of the gearbox to increase the output torque. The output end of the gearbox is rotatably connected to the left end of the grinding roller 202 via a belt or chain.

[0036] like Figure 4 and Figure 6As shown, the feeding mechanism 3 is fixedly arranged at the rear side of the polishing mechanism 2, and the feeding mechanism 3 comprises a feeding track 301 and a distribution plate 302.

[0037] The feeding track 301 is fixedly arranged above the polishing mechanism 2, one end of the feeding track 301 extends to the upper side of the driving roller 101 near the polishing mechanism 2, and the head end of the feeding track 301 points to the polishing cavity 102 on the driving roller 101; the other end of the feeding track 301 is connected with a storage tray. The feeding track 301 comprises two tracks arranged in parallel and inclined, and the relative height of the end near the driving roller 101 is lower than that of the other end.

[0040] Working principle:

[0041] In the initial state, the workpiece to be processed in the spherical processing position formed by the concave cavity 102, the driving roller 101 is stationary, the first table 2011 is at the end away from the fixing mechanism 1 under the pushing of the cylinder, the second table 2012 above is stationary, the polishing roller 202 is stationary, and a plurality of workpieces to be processed are arranged in the two feeding tracks 301, and the distribution plate 302 near the driving roller 101 is extended downward with the cylinder rod to block the workpieces to be processed, and the cylinder rod connected with the other distribution plate 302 is in the contracted state.

[0042] When the processing starts, first, the workpiece clamping action is performed, the distribution plate 302 blocking the workpiece is retracted upward with the cylinder rod, the spherical workpiece previously blocked on the feeding track 301 rolls forward under the action of gravity and is thrown to the position of the concave cavity 102. At the same time, the distribution plate 302 away from the driving roller 101 is extended downward with the cylinder rod to block the workpiece on the rear side from rolling forward. Moreover, when the thrown workpiece falls, the cylinder driving the first table 2011 is retracted, the first table 2011 is translated to the fixing device and approaches the driving roller 101, the polishing roller 202 also approaches the driving roller 101, and when the workpiece falls to the middle position of the two driving rollers 101, the polishing roller 202 contacts and presses the workpiece to clamp the workpiece.

[0043] Subsequently, when the polishing action is performed, the upper driving roller 101 is rotated under the driving of the driving motor 103, cooperates with the lower driving roller 101, and drives the clamped blank to rotate in the same direction. Figure 3 And Figure 5 As shown in the figure, the crank connecting rod mechanism 2013 drives the second table 2012 to continuously reciprocate along the slide rail, drives the polishing roller 202 arranged above the second table 2012 to reciprocate along the axis of the driving roller 101 while rotating around the axis, polishes the blank, and the spray head 4 continuously sprays water to the driving roller 101 to carry away the polishing waste and reduce the surface temperature of the workpiece.

[0044] During the polishing action, the cylinders connected to the two distribution plates 302 act, the cylinder rods of the two cylinders return to the initial state, the subsequent blank blocked by the distribution plate 302 away from the driving roller 101 rolls forward and is supplemented to the distribution plate 302 close to the driving roller 101.

[0045] After the polishing action is completed, the driving roller 101, the polishing roller 202 and the crank connecting rod mechanism 2013 all stop moving, the cylinder connected to the first table 2011 performs a pushing action, drives the first table 2011 to move away from the fixed mechanism 1, the polishing roller 202 is away from the driving roller 101, the blank in the recessed cavity 102 is free to fall under the clamping and pressing of the polishing roller 202, and the unloading is realized.

[0046] Specific embodiment two: on the basis of the specific embodiment one, the connecting structure of the shaft ears at both ends of the lower driving roller 101 is changed, a center-slotted connecting column is added to the rack, the shaft ears are slidingly connected to the center slots of the connecting column, and are positioned by bolts, so that the height is adjustable within a certain limit; similarly, the shaft ear connecting structure at both ends of the polishing roller 202 is changed, a center-slotted L-shaped right-angle connecting column is added, the shaft ears of the polishing roller 202 are slidingly connected to the center slots of the vertical edges, and are positioned by bolts, so that the height is adjustable within a certain limit, the center slots of the horizontal edges are positioned by bolts and the second table 2012, and the polishing roller 202 is horizontally locked and adjusted within a certain limit. The two distance adjustment devices are added to adapt to blanks of different sizes and realize the full-size processing capacity of the equipment.
