Crankshaft balance weight fan blade chamfering mechanism

Abstract

The invention provides a crankshaft balance weight fan blade chamfering mechanism. The crankshaft balance weight fan blade chamfering mechanism comprises a cutting unit and a flexible cutter receding unit located behind the cutting unit. The cutting unit comprises a square-column-shaped cutter body, a positioning block fixed to the front side face of the cutter body, two cutters and a rolling piece, wherein the two cutters are symmetrically fixed to the upper portion of the left side face and the upper portion of the right side face of the cutter body in the horizontal direction, the rolling piece is installed at the front end of the top end of the positioning block through a pin shaft, and the rolling face of the rolling piece protrudes out of the front side face of the positioning block and is located in front of cutter blades. The flexible cutter receding unit comprises a cutter holder, an ejector block installed in the cutter holder, a compressed spring, a baffle and an adjusting threaded rod fixedly connected with the baffle, wherein the bottom end of the cutter holder is hinged to the bottom end of the cutter body. The chamfering mechanism has the advantages of being easy to install, convenient to use, high in machining precision and capable of reducing the loss of the cutters and waste products; the chamfering mechanism is used for conducting chamfering on a crankshaft balance weight fan blade, the machining cost can be greatly reduced, the product quality can be fully guaranteed, and the obvious economic benefits are achieved.

Description

technical field [0001] The invention relates to a chamfering mechanism, in particular to a mechanism for chamfering crankshaft counterweight fan blades, and belongs to the technical field of crankshaft processing equipment. Background technique [0002] In the process of producing the crankshaft, it is often required to chamfer or round the circumference of the counterweight fan blade in sections, so as to avoid the burr on the circumference of the counterweight fan blade and play an aesthetic role at the same time. For the crankshaft workpiece with segmental chamfering (round), the counterweight fan blade segmental chamfering (circle) processing is performed with a general-purpose tool. The dimensional accuracy and surface roughness of the crankshaft workpiece are often difficult to meet the requirements, and the loss of the tool is too large, and the investment cost It is too high, and because of the various waste products produced in this process, the production cost is g...

[0002] In the process of producing the crankshaft, it is often required to chamfer or round the circumference of the counterweight fan blade in sections, so as to avoid the burr on the circumference of the counterweight fan blade and play an aesthetic role at the same time. For the crankshaft workpiece with segmental chamfering (round), the counterweight fan blade segmental chamfering (circle) processing is performed with a general-purpose tool. The dimensional accuracy and surface roughness of the crankshaft workpiece are often difficult to meet the requirements, and the loss of the tool is too large, and the investment cost It is too high, and because of the various waste products produced in this process, the production cost is greatly increased. Therefore, a low-cost, high-efficiency, segmented chamfering (circle) mechanism for crankshaft counterweight fan blades suitable for ordinary machine tools has been developed. Has great application value
