Long axis measuring deviceTechnical field
The utility model is related to a kind of long axis measuring devices, belong to field of measuring technique.
Background technology
At present in machining industry in order to need to process some longer axis, and has for the length of axis and accurately wantIt asks, but in in-process measurement, it is non-when current long axis being caused to measure since present micrometer can not possibly measure longer axisOften trouble, and measure inaccurate, it is therefore desirable to a kind of device measured dedicated for long axis.
Utility model content
The utility model aim is to provide a kind of long axis measuring device, solves current long axis and measure trouble, and is inaccurateThe problem of.
The utility model long axis measuring device, including the support plate that is obliquely installed, the left end of support plate are vertically and fixedly provided with gearPlate, support plate top are fixed with the supporting block of no less than two pieces V-types, canonical measure bar, canonical measure bar are placed in supporting blockRight end be provided with moveable amesdial, the left end of canonical measure bar is provided with can be along the gear that baffle length direction slides up and downBall, the left end of canonical measure bar, which deviates, to be contacted at center with blocking.
The support plate is iron plate, is provided with universal magnetic seat above the right end of iron plate, amesdial is fixed on Universal magneticOn seat.Universal magnetic seat can be utilized to adjust the left and right and upper and lower position of amesdial, to adapt to different-diameter and different lengthThe measurement of long axis.
The bottom of support plate is fixed with support leg.
Slideway is provided on the right side of baffle along its length, sliding block one, the right side of sliding block one are provided in slidewayWith fixation of blocking, one side of sliding block is fixed with latch, clamping screw one is provided on latch.It is adjusted by mobile sliding block oneSave the upper and lower position blocked, to adapt to different-diameter long axis measurement, and can pass through lock behind one position of mobile sliding blockTight bolt one is locked, more convenient.
It is fixed with sliding rail at the top of the left end of the support plate, the sliding block two that can be horizontally slipped on it is provided on sliding rail,Baffle is fixed on two top of sliding block, and two side of sliding block is provided with clamping screw two.It can be adjusted according to the length of measured long axisPosition of the sliding block two on sliding rail is saved, prevents from blocking because tested part is too short, does not reach and block.
The utility model compared with prior art, has the advantages that.
The specific length dimension of long axis can be fast and accurately measured by the present apparatus, solve long axis in-process measurementDifficult problem.

Specific implementation mode
With reference to embodiment and Figure of description, the utility model is described in further detail.
Long axis measuring device as shown in Figs. 1-3, including the support plate 5 that is obliquely installed, the left end of support plate 5 are vertically fixedThere are baffle 1,5 top of support plate to be fixed with the supporting block 4 of no less than two pieces V-types, be placed with canonical measure bar 3 in supporting block 4, markThe right end of locating tab assembly bar 3 is provided with moveable amesdial 6, and the left end of canonical measure bar 3 is provided with can be along 1 length direction of baffleWhat is slided up and down blocks 2, and the left end of canonical measure bar 3, which deviates, 2 to be contacted at center with blocking.
Support plate 5 is iron plate, is provided with universal magnetic seat 7 above the right end of iron plate, amesdial 6 is fixed on universal magnetic seatOn 7.
The bottom of support plate 5 is fixed with support leg 8.
Slideway 10 is provided on the right side of baffle 1 along its length, sliding block 1, sliding block one are provided in slideway 1011 right side and 2 fixations of blocking, one 11 side of sliding block is fixed with latch 12, clamping screw 1 is provided on latch 12.
It is fixed with sliding rail 13 at the top of the left end of support plate 5, the sliding block two that can be horizontally slipped on it is provided on sliding rail 1314, baffle 1 is fixed on 2 14 top of sliding block, and 2 14 side of sliding block is provided with clamping screw 2 15.
Such as when the length of workpiece is 900mm, in -0.05-0, the length of canonical measure bar 3 at this moment is length tolerance900-0.05mm, when measurement, can be placed on canonical measure bar 3 in supporting block 4, then unclamp locking nut 9, are surveyed according to standardThe diameter of gauge rod 3 adjust block 2 upper and lower position, allow block 2 touching outside the left end of canonical measure bar 3, canonical measureBar 3 is because tilt, and under the effect of gravity, sliding, which is adjacent to, to the left blocks 2, then moves universal magnetic seat 7 so that amesdial 6 pastesOutside the right end of tight standards measuring rod 3, then fixed universal magnetic seat 7 is zeroed amesdial 6, removes canonical measure bar 3, soAfter put workpiece for measurement, workpiece for measurement left end, which is adjacent to, blocks 2, and right end is contacted with amesdial 6, if amesdial 6 is in zero groove0.05 range in, then workpiece is qualified, if on the left of zero groove, workpiece is unqualified, if it exceeds 0.05 on the right side of zero grooveRange can continue to process, until qualified.
In conclusion the utility model can fast and accurately measure the specific length dimension of long axis, long axis processing is solvedDifficult problem is measured in the process.
Term "inner", "outside", " longitudinal direction ", " transverse direction ", "upper", "lower", "top", "bottom" in the description of the present invention,The orientation or positional relationship of equal instructions is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing this practicality newlyType rather than require the utility model must be with specific azimuth configuration and operation, therefore should not be understood as to the utility modelLimitation.
