Description

Die for machining eccentric wheel

Technical Field

The utility model relates to a mould processing technology field specifically is a mould of processing eccentric wheel.

Background

An eccentric wheel means that the center of the wheel is not at the point of rotation, and is generally referred to as a circular wheel, and when the circle does not rotate around the center of the circle, the eccentric wheel is formed. Eccentric wheels generally have the main purpose of generating vibration, and most eccentric wheels are round wheels, so that the round wheels are convenient to manufacture and simple in process. The eccentric wheel mechanism is evolved from a cam. The eccentric wheel mechanism is evolved from a cam. The cam is a member having a curved profile or a groove, and is generally a driving member, which performs a constant-speed rotation motion or a reciprocating linear motion. The member, which is in contact with the cam profile and which transmits power and implements a predetermined motion law, generally makes a reciprocating linear motion or oscillation, called a follower. The basic characteristic of the cam mechanism in application is that the driven member can obtain a more complex motion law. Because the motion law of the follower depends on the cam profile curve, when in application, the profile curve of the cam is designed according to the motion law of the follower. However, the disadvantage of the cam is that it is not good at transmitting power.

The existing die for machining the eccentric wheel is used for clamping the die through bolts and threads in machining, is very troublesome in installation and disassembly, wastes time, can cause the inclined condition of the clamped die to appear simultaneously, influences the machining quality of the eccentric wheel, has the same machined shape when machining the eccentric wheel, but has different eccentric center positions, causes frequent die replacement, wastes time and wastes materials.
