Abstract
The utility model relates to a tool for machining symmetrical key slots of axial parts. The tool comprises a calibration fixture and a dial gage, and the tool is characterized in that the calibration fixture consists of a V-shaped block I and a V-shaped block II which are fixed together with a rotating axis of one key slot to be machined through a bolt, a gage stand of the dial gage is adsorbed on a spindle of a machine tool, a datum plane is arranged on the V-shaped block I of the calibration fixture, an indicator of the dial gage moves vertically within the whole-journey of the datum plane and the oscillation is less than half of the symmetry tolerance of the key slot to be machined. According to the tool, the key slot machining can be realized by accurately rotating the rotating axis by 180 indexing on a common milling machine or boring machine by utilizing the characteristic that the datum plane is in parallel to the spindle of the machine tool.
Description
Technical field
The utility model relates to a kind of frock of working shaft-like part symmetrical key.
Background technology
At present, the processing of the accurate calibration of known rotating shaft symmetrical key all carrys out accurate calibration with numerical control indexing table, exists the required precision of equipment highly, must be that numerical control device could be realized, the problem that conventional equipment cannot machining high-precision symmetry calibration keyway.
Utility model content
The purpose of this utility model is to provide a kind of frock that solves the working shaft-like part symmetrical key that can carry out calibration on machine tool.
The technical solution of the utility model is: a kind of frock of working shaft-like part symmetrical key, it comprises calibration clamp, dial gauge, described calibration clamp comprises V-block I, V-block II, V-block I and V-block II are fixed together by screw and keyway rotating shaft to be processed, the gauge stand of described dial gauge is adsorbed on the main shaft of lathe, in calibration clamp V-block I, be provided with datum level, when the pointer of dial gauge in datum level global extent, move up and down swing be less than keyway symmetry tolerance to be processed 1/2 time, start to process first keyway, process after first keyway, by rotating shaft Rotate 180 degree, now datum level rotates to machine tool chief axis on one side symmetrical, again by dial gauge gauge stand around machine tool chief axis Rotate 180 degree, when the pointer of dial gauge in datum level global extent, move up and down swing be less than keyway symmetry tolerance to be processed 1/2 time, process second keyway.
Adopting symmetrical index technology of the present utility model is the principle of having utilized parallel lines, when first keyway of processing, the datum level of calibration clamp and the main shaft of lathe are parallel, when rotating shaft and dial gauge gauge stand are all processed to second keyway after Rotate 180 degree, the datum level of calibration clamp is same parallel with the main shaft of lathe, as long as the main shaft Parallel errors of twice datum level of assurance and lathe is less, indexing accuracy of its 180 degree is just higher.
Technique effect of the present utility model is, utilizes the axis of datum level and machine tool chief axis in parastate, realized countershaft on plain-milling machine or boring machine and carried out the keyway processing of accurate Rotate 180 calibration.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the utility model embodiment dial gauge calibration schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to accompanying drawing, a frock for working shaft-like part symmetrical key, it comprises calibration clamp 4, dial gauge 3, described calibration clamp 4 comprises V-block I 4-1, V-block II 4-2, and V-block I 4-1 and V-block II 4-2 are fixed together by screw 5 and the rotating shaft 7 of keyway to be processed.Described dial gauge gauge stand 2 is adsorbed on machine tool chief axis 1, on V-block I 4-1, be provided with datum level 4-3, when the pointer of dial gauge 3 in datum level 4-3 global extent, move up and down swing be less than keyway symmetry tolerance to be processed 1/2 time, now the axis of datum level 4-3 and machine tool chief axis 1, in parastate, starts to process first keyway.Process after first keyway, by rotating shaft 7 Rotate 180 degree, now datum level 4-3 rotates to machine tool chief axis 1 on one side symmetrical.Again by dial gauge gauge stand 2 around machine tool chief axis 1 Rotate 180 degree, when the pointer of dial gauge 3 in datum level 4-3 global extent, move up and down swing be less than keyway symmetry tolerance to be processed 1/2 time, now the axis of datum level 4-3 and machine tool chief axis 1, again in parastate, is processed second keyway.
While processing two symmetrical keyways, all make the axis of datum level 4-3 and machine tool chief axis 1 in parastate, guarantee that twice datum level 4-3 and machine tool chief axis 1 axis Parallel errors are less than 1/2 of keyway symmetry tolerance to be processed, thereby make the symmetry of the keyway of processing meet tolerance.Realize countershaft on plain-milling machine or boring machine and carried out the keyway processing of accurate Rotate 180 calibration.
Be more than a kind of embodiment of the present utility model, a preferred demonstration example.The scope that the utility model application is asked for protection has more than and is limited to described embodiment.All and technical scheme the present embodiment equivalence all belongs to protection domain of the present utility model.
