Abstract
The utility model discloses a kind of fixture for detecting Inner arc axiality, including base, location-plate, support block, amesdial, measurement head and to table block etc..To table block calibration clamp before measurement, the measurement head of amesdial is close to the arc surface to table block, the pointer of amesdial should go to suitable scale, rotation scale, is that the zero-bit of dial is overlapped with pointer (being zeroed), then takes out to table block, it is reloaded into detected part, part is positioned and postponed by location-plate, by rotating part, observes amesdial pointer eccentricities to detect whether part Inner arc coaxial accuracy meets technical requirements.Using Inner arc axiality detection device of the present utility model, can be according to the size of part Inner arc size, set different to table block, adjust measurement head contact position, the different Inner arc size axiality of detection, so as to improving its production efficiency, with simple in construction, operation and it is easy to use the characteristics of.
Description
Technical field
The utility model relates to field of measuring technique, specifically a kind of fixture for detecting Inner arc axiality.
Background technology
In the metering system of traditional axial workpiece Inner arc axiality, it is most of be all using the clinical centering of part its
Reference axis calculates coaxiality error and inclined in the margin of tolerance, beating after the circle bounce of table detection reference axis and tested Inner arc
Heart direction, its method operability is poor, and measurement accuracy is not high with operating efficiency, and very big problem is brought to measurement work.
In order to solve the detection of part Inner arc axiality, according to the structure and precision of detected part, one kind is devised
The special fixture of Inner arc axiality is detected, this problem is preferably resolved.
Utility model content
The technical problem that the utility model is solved is to detect Inner arc there is provided one kind for problem present in background technology
The fixture of axiality.
In order to solve the above technical problems, the technical scheme that is used of the utility model for:
A kind of fixture for detecting Inner arc axiality, including base, amesdial measurement apparatus, part positioning device, it is described
Amesdial measurement apparatus, in 5 ° of angles, is fixed on base with whole clamp body Y-axis, and the amesdial measurement apparatus includes measurement
Head (6), amesdial (7), support block (8), straight pin (9), screw (10), pinching screw (11), the support block (8) pass through circle
Pin (9) and screw (10) are fixed on base (1), and measurement head (6) is arranged on amesdial (7) top, amesdial (7) peace
Clamped in support block (8), and with pinching screw (11).Location-plate is pacified by alignment pin (4) in the part positioning device
On detected part.The part positioning device includes location-plate (2), bushing (3), alignment pin (4), positioning bushing
(12), positioning bushing (13), the detected part is by positioning bushing (13) on base (1), and location-plate (2) leads to
Alignment pin (4) is crossed to fix and on part.
, can be according to workpiece inner arc radius size using a kind of fixture for detecting Inner arc axiality of the present utility model
Difference it is different to table block to set.Positioning method for workpiece can take axle or Kong Laiding according to part own characteristic
Position, if simply unilateral axial workpiece, does not need location-plate, can be directly placed on base, otherwise, it is necessary to location-plate is positioned
Part.Meanwhile, fixture is positioned using locating shaft, installs and pickup is convenient, so as to improve its production efficiency, with structure letter
It is single, the characteristics of operating and be easy to use.
Technique effect of the present utility model：, can be with using a kind of fixture for detecting Inner arc axiality of the present utility model
Set according to the difference of workpiece inner arc radius size different to table block.What the amesdial in amesdial measurement apparatus was used
The amesdial reading of standard, 5 ° of angles of axial dipole field during installation, be in order to more preferably, more easily adjustment measurement head and part in
Part Inner arc axiality detection case can be clearly viewed in window on the contact position of circular arc, location-plate.The device has
The characteristics of simple to operate, installation and pickup facilitate, while strict guarantee part crudy, also overcomes traditional detection numerous
Superfluous measurement preparation, measurement position is without limitations, and has higher reliability for measured value, substantially reduces
Process-cycle, improve operating efficiency.
