Embodiment Construction

[0015] The specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0016] A shearing blade turning fixture of the present invention includes a shaft seat 1 and a pressure plate 2, and is characterized in that the pressure plate 2 is mounted on the shaft seat 1 through a locking screw 4, and an adjustment screw 5 is screwed into the pressure plate 2, and the adjustment screw 5 is against Hold shaft seat 1.

[0017] A positioning head 3 is provided at the center point of the shaft seat 1 .

[0018] The pressing plate 2 is provided with grooves.

[0019] When in use, the shaft seat 1 is fixed on the three-jaw chuck of an ordinary lathe, the workpiece 6 leaves a turning allowance hole and is set on the positioning head 3, the pressure plate 2 presses the workpiece 6, and the locking screw 4 passes through the pressure plate 2 and is screwed into the shaft. Se...

Abstract

The invention discloses a cutting blade turning clamp which comprises a shaft seat (1) and a pressing plate (2). The pressing plate (2) is installed on the shaft seat (1) through the locking screw (4), the adjusting screw (5) is screwed into the pressing plate (2), and the adjusting screw (5) abuts against the shaft seat (1). The device is rapid in clamping, high in turning efficiency, high in percent of pass, simple in structure, easy to machine and low in cost.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a turning fixture for a shear blade. Background technique [0002] For a long time, the machining of the inner hole of the experimental shearing blade has been performed on a common lathe using a four-jaw chuck for clamping and turning. Since the counterbore of the shearing blade is coaxial with the central through hole, a turning allowance should be left before heat treatment, and the inner hole should be fine-bored after heat treatment. When turning the inner hole, each shear blade must be aligned, the turning efficiency is low, the processing cycle is long, and the delivery node is affected. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a fast clamping, high turning efficiency, high pass rate, simple structure, easy processing, low cost shearing blade turning fixture. [0004] Purpose of the pres...
