Embodiment 1
[0014] Such as figure 1 As shown, this embodiment describes the method of preventing burrs suitable for eccentric intermittent cutting of the car, and the processing is as follows figure 1 As shown in the crankshaft 1 of the automobile air-conditioning compressor, the specific design requirement for machining the first step surface 2 of the shaft section is that the diameter D1 is 12 cm and the round chamfer with a radius R of 2 cm is used. The constant k1 is 0.4cm, then use a step milling cutter to process a step surface with a diameter of 11.6cm, the diameter of the step circumference 3 is 12cm according to the design requirement, and there is a round chamfer 4 transition of R2×45° between the step surface and the circumferential surface, and then Then increase processing k2×45° small chamfer 5 at the transition position, the k2 is 0.2cm. The final result is as figure 2 As shown, when machining the step surface of the central section at the same time, the design requires ...

Abstract
The invention discloses a burr preventing machining method suitable for turning eccentric interrupted cutting. The method is characterized in that when the step face of a shaft is machined, the end face and the outer circle of the step face are in transition through a chamfer d or a fillet r, the diameter of the end face of the step face required by a drawing is D1, the radial diameter of the stepis D1, the diameter of the end face of the actually-machined step face of the step face is D1-k1, k1 is a constant which is set according to experience and is smaller than the transition distance d or r, then a k2*45-degree small chamfer is additionally machined at the transition position, and k2 is smaller than k1 and is also a constant. According to the machining method, through the arrangementof the special machining procedures, the machining procedures are changed under the conditions that the design requirements of the workpiece are not affected and the performance of the workpiece is guaranteed, so that burrs are effectively removed, the subsequent manual deburring procedure is avoided, the machining efficiency is greatly improved, and the machining method is particularly suitablefor machining a crankshaft for an automobile air conditioner compressor.
Description
technical field [0001] The invention relates to a machining method for eccentric intermittent cutting, in particular to a burr-preventing machining method suitable for eccentric intermittent cutting. Background technique [0002] The machining method of interrupted cutting of eccentric shafts in the prior art is a machining method for workpieces with multiple axial sections and forming stepped surfaces, and is especially suitable for machining crankshafts. In the processing of each step surface, according to the design requirements, higher machining accuracy is required, but due to the formation of multiple step surfaces, burrs are often formed, which need to be manually removed later, which increases the processing time of the workpiece and affects the processing. efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention provides a burr prevention machining method suitable for eccentric intermittent cutting, which can effe...
