Description
Technical field:
The utility model relates to the high-speed track train and processes a kind of boring cutter with motor casing right boring macropore, relates in particular to the compound boring cutter of track train with motor casing right boring macropore.
Background technology:
The structure of high-speed track train usefulness motor casing which is provided with the hole that stator is installed as shown in Figure 1, and the two ends in this hole all have step, is difficult to carry out high accuracy processing with conventional boring cutter.In mechanical processing industry, have the diameter through hole of step for a diameter through hole or an end, though can satisfy requirement on machining accuracy with traditional boring cutter, must be through heavy boring, half right boring and the processing of right boring multiple operation, it is longer to process the required time, machined expense height.
The utility model content:
The purpose of this utility model provides a kind of thick tool-bar for accurately boring device that there is stepped hole at two ends of processing, and it can just can be finished the high accuracy processing of high-speed track train with double step macropore on the motor casing by one-pass.
The technical scheme that the utility model is taked is as follows:
A kind ofly process the thick tool-bar for accurately boring device that there is stepped hole at two ends, comprise rotary main shaft, balance knife bar, adjustable heavy boring holder, heavy boring cutter hub, heavy boring blade, adjustable right boring holder, right boring cutter hub, right boring blade, holder trip bolt and cutter hub trip bolt, the heavy boring blade is removably mounted on the heavy boring cutter hub, the heavy boring cutter hub is fixedly mounted on the adjustable heavy boring holder by the cutter hub trip bolt, and adjustable heavy boring holder is installed on the balance knife bar by the holder trip bolt; The right boring blade is removably mounted on the right boring cutter hub, the right boring cutter hub is fixedly mounted on the adjustable right boring holder by the cutter hub trip bolt, adjustable right boring holder is installed on the balance knife bar by the holder trip bolt, the balance knife bar is fixedly mounted on the rotary main shaft, the cutting tips of heavy boring blade to the distance and the cutting tips of right boring blade between the rotary main shaft rotation between the rotary main shaft rotation apart from difference be 0.1～0.5 millimeter, phase place angle between the two is 10 °～30 °; Be provided with balance weight on the balance knife bar, after adjustable heavy boring holder, heavy boring cutter hub, heavy boring blade, adjustable right boring holder, right boring cutter hub, right boring blade, holder trip bolt and cutter hub trip bolt were installed in the balance knife bar, the balance knife bar satisfied requirement for dynamic balance.
Because high-speed track train motor casing is an accurate die casting, though the requirement on machining accuracy height of the double step macropore on it, but heavy boring blade in this thick tool-bar for accurately boring device and right boring blade axially isoplanar are arranged, circumferential misalignment distributes, allowance between heavy boring and the right boring can artificially be regulated, simultaneously, whole device has passed through dynamic balance running, because allowance is less, it is less to add the vibration that man-hour, whole device produced, heavy boring blade and right boring blade can not only be processed the step surface at two ends simultaneously, and machining accuracy also can meet design requirement, through reality processing checking, the utility model can carry out thick right boring synchronous processing to macropore, it is simple in structure, cheap, only be the 30%-40% of standard compound tool, machining period has only 1/3～1/2 of common boring processing.Have the machining accuracy height, machining accuracy can reach IT4, roughness Ra 0.2, processing cost is low, saving of labor's energy-saving effect is remarkable.
