A kind of burr removing machine tool of axial workpiece
Technical field
The invention belongs to field of mechanical technique, relate to the burr removing machine tool of the axial workpiece of a kind of burr removing machine tool, particularly a kind of double thread.
Background technology
Axial workpiece is the conventional spare and accessory parts in plant equipment processing and production process, and it is mainly used to support transmission parts, transmitting torque and bearing load etc.According to using needs, some axial workpiece need to design the flat side of spline who prevents that axle from rotating.This class parts machining process can only be the flat side of Milling Process spline after screw thread machines, the flat side's rear thread of milling and flat side's intersection just produce more burr, these burrs have a strong impact on assembling and the surface quality of part, some parts also can all design the flat side of spline and screw thread in two ends, how effectively to remove fast these burrs, improve working (machining) efficiency and reduce production costs, become the problem of technical staff's research.
In prior art, conventionally adopt workman to remove the mode of burr with file or steel wire rotary brush, such mode working (machining) efficiency is low, or by simple deburring equipment, axial workpiece is processed.For example, Chinese patent [application number 201120021771.0; Granted publication CN202052997U] disclosed a kind of thread burring machine, be made up of motor, motor mounting plate, rotating shaft, screw die installation sleeve, five tooth plate teeth, v-shaped bearing plate and base, motor mounting plate and two v-shaped bearing plates are vertically fixedly connected on above base successively.Motor is fixed on the motor mounting plate one side of v-shaped bearing plate dorsad, rotating shaft is connected with the turning cylinder of motor through motor mounting plate, screw die installation sleeve is sleeved in rotating shaft, in the end hole of screw die installation sleeve, be fixedly connected with five tooth plate teeth, on the inner periphery of five tooth plate teeth, be distributed with five circular grooves, between adjacent circular groove, form double wedge.
Above-mentioned thread burring machine can be realized the threaded portion deburring to part, has replaced existing manual operation, has improved working (machining) efficiency.But the problem that this thread burring machine exists is: 1, this equipment once can only complete the deburring of a workpiece threaded one end portion, and working (machining) efficiency still has much room for improvement; 2, the location inconvenience of workpiece, workpiece is easily subjected to displacement in process, affects machining accuracy; 3, workpiece (particularly for axial workpiece) is difficult to ensure with the concentricity of screw die installation sleeve (screw die).
