[0023] The linkage plate 10 is provided with a strip groove 101, and the oil cylinder fixing seat is provided with a protrusion 141, and the protrusion 141 is matched and connected with the strip groove 101.

[0024] The manipulator assembly 19 is connected to the fixing seat 17 at the end of the cylinder through a limit screw 18.

[0025] A spring 30 is arranged between the lifting rod 6 and the roller 9 .

[0026] The manipulator assembly 19 includes a lifting plate 24 connected to the end of the cylinder 13, and a through hole is set at the lower end of the lifting plate 24 for the grinding head 21 to extend into the workpiece 8 to be processed. A stopper 25 is set on one side of the lifting plate, and the lower end of the stopper 25 abuts against one side of the workpiece 8 to be processed. A lifting block 26 is set on the other side of the workpiece 8 to be processed. The lifting block 26 is set on the lifting plate 24, and a connecting member 27 is also set on the lifting plate 24. The connecting member 27 is fixedly connected to the material storage stop rod 28.

[0027] The material storage stopper 28 is arranged in an L-shape, and the distance between the material storage stopper 28 and the lifting plate 24 is the same as the diameter of a workpiece 8 to be processed;

[0028] The profile of the material storage stopper rod 28 abuts against the processed workpiece to prevent the processed workpiece from falling, and at the same time, the processed workpiece abuts against the workpiece to be processed.

[0029] The lifting plate 24 is also connected to the discharge guide block 20 .

[0030] The clamp assembly 15 includes an electromagnetic suction cup 29 arranged at a position corresponding to the through hole. The front end face of the horizontal spindle protrudes from the vertical surface of the bent plate 2 and is connected to the electromagnetic suction cup 29. The port outer diameter of the electromagnetic suction cup 29 is consistent with the outer circle size of the workpiece 8 to be processed. A clamp bracket 22 is also arranged on the fast feeding guide back plate 3.

[0031] The clamp bracket 22 is arranged in a V-shape, and the shape of the clamp bracket 22 is complementary to the shape of the lifting plate 24 of the robot assembly 19 .

[0032] The outer side of the intermediate material guiding back plate 23 abuts against the limiting guide block 11 , and the limiting guide block 11 is fixedly arranged on the fast feeding guide back plate 3 to limit the displacement of the intermediate material guiding back plate 23 .

[0033] The present invention further discloses a method for precision machining of inner holes using the horizontal inner rounding device:

[0034] Step 1: Adjust the limit screw 18 so that when the piston rod of the oil cylinder 13 is retracted to the shortest, the feed guide back plate 4 and the intermediate guide back plate 23 are connected together to form a track for the workpiece 8 to be processed to move, which corresponds to the space reserved in the manipulator assembly 19 for storing the workpiece 8 to be processed (the distance between the stop block 25 and the lifting block 26);

[0035] Step 2: Place the workpiece 8 to be processed on the track of the feed guide back plate 4 so that the workpiece 8 is stuck on the feed guide block 5;

[0036] Step 3: Turn on the oil cylinder 13, the oil cylinder 13 starts to move, and the steps of loading, feeding and unloading are realized at the same time. The oil cylinder 13 extends, driving the linkage plate 10 to rotate, so that the linkage plate 10 lifts the lifting rod 6 through the roller 9, and the lifting rod 6 lifts the workpiece 8 to be processed through the lifting block 7, passing the height of the feeding guide block 5, completing the loading process of a single workpiece 8 to be processed. The workpiece 8 moves to the side wall of the lifting plate 24 by its own weight in the track and abuts against the side wall of the stopper 25, waiting to be unloaded. One cycle, the feeding process is completed. During the movement of the workpiece 8 in the track, the oil cylinder 13 drives the lifting plate 24 to move downward, and the lifting plate 24 is provided with a workpiece 8 that has fallen in the previous cycle. The lifting plate delivers the workpiece 8 to the corresponding position of the electromagnetic suction cup 29, and the loading and unloading processes are completed at the same time; during the unloading process, the storage lever 28 moves downward with the lifting plate, and the processed parts 31 are discharged along the shape of the discharge guide block 20 because there is no constraint of the storage lever 28;

[0037] Step 4: Processing: the electromagnetic chuck sucks the workpiece 8 to be processed, and the grinding head 21 extends into the through hole of the lifting plate 24 and enters the inner circle of the workpiece 8 to start processing.

[0038] Step 5: Cutting, the cylinder 13 contracts, driving the lifting plate 24 to move upward, and at the same time the lifting block 26 drives the processed part 31 to separate from the electromagnetic suction cup 29. When it moves to the corresponding position of the port of the intermediate material guide back plate 23, the processed part 31 uses its own weight to move to the material storage gear rod 28 and abuts against the material storage gear rod 28. At this time, the workpiece 8 to be processed is separated from the constraint of the block 25, and moves from the intermediate material guide back plate to the lifting plate 24 (the distance between the block 25 and the lifting block 26), and abuts against the processed part 31. When the cylinder is ready to extend, the lifting plate 24 sends the workpiece 8 to be processed into the corresponding position of the electromagnetic suction cup. Since the distance between the material storage gear rod 28 and the lifting plate 24 is the diameter of a workpiece 8 to be processed, the newly entered workpiece 8 to be processed just falls into the lifting plate, completing the cutting process.

[0039] In order to ensure that the entire processing process is more accurate, a position sensor 142 can be set at the up and down strokes of the cylinder to confirm the position of the cylinder.
