Embodiment Construction

[0018] combine Figure 1 to Figure 6 , a method for turning an eccentric shaft, comprising the steps of:

[0019] Provide processing machine tools, several optional eccentric collets 1, elastic collets 2 and eccentric shaft workpieces 3. Only one eccentric collet 1 is shown in the figure. The above-mentioned eccentric collet 1 is provided with an eccentric shaft hole 101 capable of satisfying a set eccentricity, and L in the figure is the set eccentricity. Preferably, from the perspective of the cross-sectional structure of the eccentric collet, the cylinder wall gradually thickens from top to bottom, and a lower opening 102 parallel to the axis (axis line) of the eccentric collet is provided on the bottom cylinder wall; The wall is provided with an inner notch 103 recessed from the side of the eccentric shaft hole to the cylinder wall for a section. The inner notch is also parallel to the axis of the eccentric collet, and the position of the inner notch is directly opposite...

Abstract

The invention discloses a method for turning an eccentric shaft. The method is characterized by comprising the following steps of: a. providing a machining machine tool, a plurality of alternative eccentric cylinder clamps, an elastic cylinder clamp and an eccentric shaft work piece, wherein the eccentric shaft work piece is placed into the eccentric cylinder clamps through an eccentric shaft hole, and the eccentric cylinder clamps can be placed into the elastic cylinder clamp from an opening expanding end of the elastic cylinder clamp; and b. fixing the elastic cylinder clamp on a machine tool clamp head on the machining machine tool to tightly match a tapered surface of the opening expanding end of the elastic cylinder clamp with an inner tapered surface of a corresponding end of the machine tool clamp head, and enable an axis of the elastic cylinder clamp to be concentric with a main shaft of the machining machine tool; placing the eccentric cylinder clamps into the elastic cylinder clamp, wherein the eccentric cylinder clamps and the elastic cylinder clamp are matched in a small interference fit manner; placing the eccentric shaft work piece into the elastic cylinder clamps; and then, machining and operating the eccentric shaft work piece. The method disclosed by the invention is beneficial for replacing the eccentric cylinder clamps with different specifications; and the aim of rapidly and highly-precisely producing eccentric shafts by various machine types in a batch is achieved through rapidly replacing the eccentric cylinder clamps.

Description

technical field [0001] The invention relates to a processing method for an eccentric shaft, in particular to a method for turning an eccentric shaft. Background technique [0002] Existing methods for turning eccentric shafts often use fixtures such as cans or four-jaws in the implementation process. Although these turning methods can also process eccentric shafts that meet the specifications, they also have certain technical defects. The existence of the above-mentioned technical defects also determines that the existing method for turning eccentric shafts is not suitable for fast, high-precision, multi-variety mass production of eccentric shafts. This shows, the method for existing turning eccentric shaft also needs further improvement. Contents of the invention [0003] The task of the present invention is to solve the deficiencies in the method for turning an eccentric shaft in the prior art, and provide a method for turning an eccentric shaft. [0004] Its technical...
