Design of eccentric structure in bearing milling machine

In the segmentation processing of the reducer housing, the first section of the automatic line milling reducer cover large plane and drill hinge process positioning pin hole, machining bearing cover mounting surface and screw hole; the second section of the automatic line rough, semi-finished two Mounting holes for the bearing bore and the shaft tube at both ends; the third section of the automatic line of the automatic split-type differential assembly and the bearing bore of the active bevel gear. The full line productivity is 120 pieces/h.

Firstly, the bearing cover mounting surface, the drill screw hole, the coarse, semi-finished, fine-tuned active bevel gear bearing hole, the drill hinge positioning pin hole, and the milling reducer mounting surface are milled. The two bearing holes of the precision-mounted differential assembly and the two bearing holes of the active bevel gear. A step-and-step conveyor and an automatic loading and unloading device are used on the machine. The main feature of these two special mixing beds is that a pair of vertical mixing heads and a horizontal boring head are used to agitate the pair of vertically intersecting bearing holes in a single clamping, ensuring the positional accuracy of the two holes.

A unique eccentric mechanism is mounted on the mast of the vertical hoe for radial feed. The stirring rod is equipped with three blades, which in turn boring the bearing holes of the three active bevel gears of the same axis and the inner end faces thereof, and the horizontal building head adopts one hard alloy stirring rod to sequentially lock the two differential assemblies. Bearing holes. After the pores are precisely fused, the workpiece is automatically pushed to the end point and, after cleaning, sent to the assembly line.

The assembly automatic machining generation line completes the rough and refined hole, the end face, the drilling, the chamfering, the tapping and the like of the final reducer shell and the bearing cover assembly. Since the assembly is machined on this line, other parts of the process, such as the process base, the large flange plane and the two positioning pin holes, have been completed on the line. (Finish)

The whole line is composed of wood chipping, drying, crushing, moisture detection & regulation, pelletizing, cooling, sieving and packing process, with consecutive and reasonable process routing. Every standalone machine is of high performance, the assembly is with compact structure, small occupation, low consumption and high efficiency. Each standalone machine will design and manufacture in accordance to the demands of clients. Installation will be carried out and guided by professional technician.
