Background technology
In machining,, adopt taper plug gauge to tint usually to observe the way of its contact area to check the tapering of taper hole for the less taper hole class part in aperture; But, precision higher big taper hole part big for the aperture carries out the scene and detects, and adopts above method then to seem particularly heavy and difficult.Usually adopt the three-dimensional gauge to carry out so detect this type of large-scale taper hole.So not only increased the detection cost, and operation inconvenience.The operator must pull down censorship from lathe with part, in case when finding that taper hole is defective and reprocessing, because of benchmark is destroyed again the clamping adjustment, efficient is very low, is difficult to adapt to and produces the needs that detect in enormous quantities.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists, and provides a kind of simple in structure, applied widely, easy to operate; Accuracy of detection is high; Low cost of manufacture can be used on lathe at random, reduces labour intensity; Enhance productivity the large-scale taper hole tapering pick-up unit of the large-scale taper hole tapering of ability fast detecting.
The purpose of the utility model realizes that through following technical scheme it comprises a crossbeam, and described crossbeam and regulating arm and gage beam connect and compose an adjustable triangular framing respectively successively through hinge; Said crossbeam is provided with straight trough and " ten " font type groove, is respectively applied for fixation measuring arm and regulating arm; Said crossbeam " ten " word groove place is demarcated has the angle index value, shows the angle of gage beam and vertical direction, makes gage beam approximate parallel with the taper hole conical surface when measuring; Said gage beam is provided with round head screw and the calculation type digital display centimeter that is used to measure the taper hole tapering, and they are regulated and locking by two set screw that are installed on the gage beam respectively.
Said gage beam one end fixes in the beam vertical groove through hinges fixing, and the other end is connected with regulating arm through hinge; Said regulating arm one end is connected with gage beam through hinge, and the other end can move in crossbeam " ten " font groove through hinge is fixing, and can be through the locking of the set screw on the crossbeam.Said crossbeam lower surface requires to have very high flatness and smooth finish, to reduce measuring error.
Said calculation type digital display centimeter is multi-functional dial gauge, can be through direct demonstration taper error angle value is set.Use the standard taper piece that cubing is carried out the zero clearing setting before measuring, put into the detection part and can read the taper error value that jitter values reflected under the specific range from the calculation type digital display centimeter.
The utlity model has convenient to operation, measuring accuracy can compare favourably with the three-dimensional gauge; In practical application, detect more stable reliable; Do not need the operator that part is pulled down from lathe and can obtain accurate measurement result; Greatly reduce working strength of workers, improved characteristics such as production efficiency.

Embodiment
To combine accompanying drawing and embodiment that the utility model is described further below.Shown in Figure 1, described large-scale taper hole tapering pick-up unit, it comprises a crossbeam 1, described crossbeam 1 connects and composes an adjustable triangular framing with regulating arm 3 and gage beam 4 respectively through hinge successively; Said crossbeam 1 is provided with straight trough and " ten " font type groove, is respectively applied for fixation measuring arm 4 and regulating arm 3; " ten " word groove place of said crossbeam 1 is demarcated has the angle index value, shows the angle of gage beam 4 and vertical direction, makes gage beam 4 approximate parallel with the taper hole conical surface when measuring; Said gage beam 4 is provided with round head screw 5 and the calculation type digital display centimeter 8 that is used to measure the taper hole tapering, and they are regulated and locking by two set screw 6,7 that are installed on the gage beam 4 respectively.
Said gage beam 4 one ends fix in crossbeam 1 vertical channel through hinges fixing, and the other end is connected with regulating arm 3 through hinge; Said regulating arm 3 one ends are connected with gage beam 4 through hinge, and the other end can move in " ten " font groove of crossbeam 1 through hinge is fixing, and can be through 2 lockings of the set screw on the crossbeam 1.Said crossbeam 1 lower surface requires to have very high flatness and smooth finish, to reduce measuring error.
Shown in Figure 3, a kind of measuring method of aforesaid large-scale taper hole tapering pick-up unit, this method is: carry out the zero clearing check and correction before the measurement earlier; When measuring part, device is put into the part taper hole then, and translation makes the round end gib screw vertically contact the part conical surface, this moment, the reading of calculation type digital display centimeter was the taper error of the part taper hole of surveying.
Shown in Figure 2; Described zero clearing check and correction is: cubing is placed on A, two isometry blocks of B, and wherein the high piece of A is regular side's body, and the high piece of B is the prismatoid that has normal cone; Its tapering is made according to the tapering that detects part; And require the conical surface to have very high flatness and smooth finish, and during check and correction the cubing gage beam is made that near the high piece conical surface of B fixedly round head screw vertically contacts the high piece conical surface of B, then digital display centimeter 8 zero clearings are got final product;
Embodiment:
As shown in Figure 1, crossbeam 1, regulating arm 3 and gage beam 4 are connected through the hinge and constitute an adjustable triangular framing.Said crossbeam 1 is provided with straight trough and " ten " font type groove, is respectively applied for fixation measuring arm and regulating arm.Said crossbeam 1 is marked with angle index, the angle angle of gage beam 4 and vertical direction when expression moves to this position when regulating arm 3 drive gage beams 4.Specified distance is provided with round end gib screw 5 and calculation type digital display centimeter 8 on the said gage beam 4, is regulated and locking by the set screw 6 and 7 that is installed on the gage beam respectively.Said regulating arm 3 moves to pairing scale place according to the tapering angle of survey taper hole with the adjustable hinge end, and through 2 lockings of the lock-screw on the crossbeam 1.Said calculation type digital display centimeter 8 can return to zero setting, calculate the transformation function setting, can the runout error value of specific range tapering be converted into the angular error value, be convenient to the operator and directly observe testing result.
As shown in Figure 2, before measuring this device is carried out the zero clearing check and correction.Cubing is placed on A, two isometry blocks of B.Wherein A is regular side's body, and B is the prismatoid that has normal cone, and its tapering is made according to the tapering that detects part, and requires the conical surface to have very high flatness and smooth finish.During check and correction the cubing gage beam is made that near the B piece conical surface fixedly round head screw 5 vertically contacts the B piece conical surfaces, then digital display centimeter 8 zero clearings are got final product.
As shown in Figure 3, when measuring part this device is put into the part taper hole, and translation makes the round end gib screw 5 vertical contact part conical surfaces, this moment, the reading of calculation type digital display centimeter was the taper error of the part taper hole of surveying.
When using this cubing to detect the taper hole of different apertures, different taperings, only need to regulate the regulating arm of cubing, the isometry block B that matches corresponding tapering simultaneously gets final product, and is very convenient.
