Abstract

The utility model discloses a head frame milling-shaped tool, and belongs to the field of milling-shaped tools. The head frame solves the problems that when an existing head frame is bored and milled, the head frame and a cutter vibrate synchronously, the difference of thicknesses of different positions of a processed workpiece is large, the surface of the processed workpiece is very rough, processing zero aligning and correcting are carried out when the workpiece is processed every time, and processing efficiency is low. The head frame milling-shaped tool comprises a base plate, compression springs and two positioning pins, wherein the base plate is a flat plate, the upper end face of the base plate is provided with two hinge pin holes which communicate the upper end and the lower end of the base plate, one ends of the two positioning pins penetrate through the two hinge pin holes respectively, the upper end face of the base plate is provided with blind holes, the number of the compression springs and the number of blind holes are many and are the same, the blind holes are evenly distributed in the upper end face of the base plate, and each blind hole is internally provided with one compression spring in a fixed mode. The head frame milling-shaped tool is used for boring and milling the head frame workpiece.

Description

A kind of frame mills the shape frock

Technical field

The utility model relates to a kind of frame and mills the shape frock, belongs to the shape frock field of milling.

Background technology

China still belongs to a difficult problem for the processing of light-alloy thin wall type and the distortion after processing at present, the processing of frame just belongs to this type of, the technological requirement of this workpiece is that sidewall and bottom surface wall thickness are 3mm, and Workpiece structure is thin without reinforcement, the technological requirement workpiece bottom is taked boring-mill work, flatness 0.2, in process, cutter and workpiece produce resonance, cause the wall thickness at each position of workpiece after processing to differ larger, the minimum place of wall thickness is the 2mm left and right, simultaneously, processing rear surface roughness extreme difference, flatness can't guarantee, simultaneously, workpiece all needs to carry out centering and check and correction processing zero point man-hour adding at every turn, working (machining) efficiency is also lower.

The utility model content

The utility model is for solving an existing frame in boring-mill work, frame and cutter produce resonance, cause the thickness at each position of workpiece after processing to differ large and surface roughness extreme difference, simultaneously, workpiece all needs to carry out centering and check and correction processing zero point, the problem that working (machining) efficiency is lower man-hour adding at every turn.

Provide a kind of frame to mill the shape frock for solving the problems of the technologies described above, described frock comprises base plate, Compress Spring and two alignment pins, base plate is dull and stereotyped, be provided with two pin shaft holes on the upper surface of base plate, two pin shaft holes all connect the two ends up and down of base plate, one end of two alignment pins is through respectively on two pin shaft holes, also be provided with blind hole on the upper surface of base plate, described Compress Spring is a plurality of with blind hole and both quantity is identical, a plurality of blind holes are dispersed on the upper surface of base plate, all are fixedly installed a Compress Spring in each blind hole.

The utility model compared with prior art has following beneficial effect:

1, the utility model adopts the bottom surface of Compress Spring supporting member frame workpiece, improved the rigidity of process system, reduced the vibration in processing, the thickness that has effectively improved each position of the rear workpiece of processing differs large and the relatively poor problem of surface roughness, has improved crudy.

2, the utility model in use, two bearing pin locating holes that carry on workpiece are enclosed within respectively the upper end of two alignment pins, can make workpiece effective location on the upper surface of base plate, workpiece does not need again centering and check and correction processing zero point man-hour adding at every turn, thereby reduced labourer's labour intensity, improved working (machining) efficiency.
