[0048] The remaining structure is the same as that of embodiment 4.

[0049] Working principle of the application:

[0050] Firstly, the semi-finished connecting rods that are processed in advance are uniformly put into the material cavity 61, the semi-finished connecting rods fall to the bottom of the cavity in an orderly manner through the Y-shaped material cavity 61, and are stopped from falling by the plurality of partition pieces 65 on both sides, and are stored in the material cavity 61.

[0051] Secondly, the servo motor 42 is started to drive the corresponding rotating roller 41 to rotate, and then drive the conveying belt 43 to start rotating around, at the same time, the four first lifting cylinders 5 are started synchronously, the corresponding side plate 4 is pushed by the lifting rod 51 to drive the conveying belt 43 to rise in height, the side plate 4 rising will also drive the corresponding L-shaped push rod 44 to rise, so as to drive the partition piece 65 to rotate through the meshing teeth, and then make the semi-finished connecting rod at the bottom fall on the surface of the conveying belt 43, and move a specified distance on the surface of the conveying belt 43 through the rotation of the conveying belt 43.

[0052] Third step, synchronously start four first lifting cylinders 5 to drive the corresponding side plate 4 to descend, so that the corresponding L-shaped push rod 44 descends, thereby driving the separating piece 65 to rotate reversely through the meshing teeth, so that the bottommost semi-finished product connecting rod is blocked and cannot continue to descend, according to the operation steps of the second step, the semi-finished product connecting rod is lowered at a constant frequency, ensuring that several semi-finished product connecting rods arranged at equal intervals fall on the conveyor belt 43 and are uniformly conveyed to the position opposite to the corresponding first special-shaped limiting seat 2 and the second special-shaped limiting seat 3;

[0053] Fourth step, synchronously start four first lifting cylinders 5 to drive the corresponding side plate 4 to descend, so that the conveyor belt 43 descends by a greater height, thereby making the large head and the small head at both ends of the semi-finished product connecting rod respectively enter the corresponding first special-shaped limiting seat 2 and the second special-shaped limiting seat 3, completing rapid feeding, and then starting the limiting cylinders corresponding to the two sides of the several first special-shaped limiting seats 2 and the second special-shaped limiting seats 3 to push the corresponding square extrusion pieces 23 and the arc-shaped extrusion pieces 33 to extrude and abut at the large head and the small head at both ends of the semi-finished product connecting rod, ensuring that the semi-finished product connecting rod is fixed in position during the machining operation and will not deviate;

[0054] Fifth step, after completing the machining operation on one side of the connecting rod, the square extrusion pieces 23 and the arc-shaped extrusion pieces 33 corresponding to the limiting cylinders are retracted, the finished product connecting rod is no longer limited and fixed, four first lifting cylinders 5 are synchronously started again to drive the corresponding side plate 4 to ascend, thereby driving the conveyor belt 43 to ascend in height, and the bottom of the several finished product connecting rods is in contact with the surface of the conveyor belt 43, until the large head and the small head at both ends of the connecting rod are separated from the corresponding first special-shaped limiting seat 2 and the second special-shaped limiting seat 3, and the conveyor belt 43 continues to rotate around by starting the servo motor 42;

[0055] In the sixth step, the connecting rods with one processed surface are carried by the conveying belt 43 to the end away from the storage box 6, at the same time, the turnover motor 75 is started to rotate the corresponding rotating wheel 72, thereby rotating the conveying belt 73 and the plurality of partitions 74, and then the second lifting cylinder 76 is started to lift the turnover box 7 as a whole, so that the height of the conveying belt 73 is slightly lower than the height of the conveying belt 43, facilitating the connecting rods to drop onto the conveying belt 73, and cooperating with the movement of the conveying belt 43 to make the connecting rods completely slide onto the partitions 74 and be stored in the inner cavity of the turnover box 7 according to the above-mentioned manner. When the partitions 74 rotate to the end away from the conveying belt 43, the connecting rods on the conveying belt 73 will be forced to turn over and fall to the bottom of the inner cavity of the turnover box 7, and when the partitions 74 rotate to the position close to the conveying belt 43 again, the second lifting cylinder 76 is started to lift the turnover box 7 as a whole, so that the connecting rods slide onto the conveying belt 43 again, at this time, the conveying belt 43 reverses the rotation to make the connecting rods on the conveying belt 43 be arranged at equal intervals, and finally be moved to the corresponding special-shaped limiting seat, and then the first lifting cylinder 5 is started to lower the height of the conveying belt 43, so that the connecting rods after the turning over are clamped into the corresponding special-shaped limiting seat again, and the connecting rod turning over operation is started.
