Abstract
The utility model discloses a check tool which can check a taper angle accurately and rapidly, can remove unqualified products in batch products to reduce or prevent slip faults and can be used for rapid measurement when processing taper holes. The taper angle check tool comprises a measuring sleeve and a measuring rod. The taper angle check tool is characterized in that a dial gauge is arranged at the top of the measuring sleeve; a big cylinder is arranged at the bottom of the measuring sleeve; the measuring rod penetrates from the bottom of a sleeve hole of the measuring sleeve and is arranged in the sleeve hole via a positioning screw and a positioning slot so that the measuring rod can move axially and limitedly in the sleeve hole; a small cylinder is arranged at the bottom of the measuring rod; and a spring is arranged between the big cylinder and the small cylinder.
Description
Technical field
The utility model relates to cubing, specifically a kind of cone angle cubing.
Background technology
At present, the situation for connecting for conical profile between the twin-tub air compressor machine of steyr engine and the injection pump transmission gear in order to guarantee quality of fit, satisfies the regulation requirement, and the taper hole number of degrees of injection pump transmission gear are 11 ° 25 ' 16 "
-3 ' 16 ", make it behind assembly, reach effective connection effect, be very important so the accurate measurement of the cone angle number of degrees is controlled with strictness.Though three-dimensional also can accurately be measured its angle to taper hole, its speed is too slow, can not adapt to the needs of check in enormous quantities.And; especially for EGR Europe trimotor; because of causing driving torque, the injection pressure increase increases; occur escaping the fault of angle of advance in test run in a large number through regular meeting, one of its reason is exactly because taper hole number of degrees part is overproof; cause in connection that the secondary contact of circular cone is bad to cause it to skid; this can design accurately a kind of with regard to an urgent demand and measure the cubing of cone angle apace, can reject unacceptable product in bulk article, to reduce or to prevent the generation of sipping fault.
Summary of the invention
To be solved in the utility model is the problems referred to above that prior art exists, and aims to provide accurately a kind of and measures the cubing of cone angle apace.
The technical scheme that addresses the above problem employing is: the cone angle cubing, comprise and survey cover and measuring staff, it is characterized in that described survey cover top is provided with dial gauge, the bottom of surveying cover is provided with big column, described measuring staff penetrates from the bottom of surveying the trepanning that overlaps, and is arranged in the described trepanning by dog screw and locating slot, makes measuring staff can do limited axially-movable in trepanning, the measuring staff bottom is provided with small column, is provided with spring between described big column and the small column.
The principle that the utility model is pressed is as follows:
The tapering a of measured piece can use formula (1) expression
In the formula
D-surveys cover big column diameter, is definite value
D-measuring staff small column diameter is definite value
Distance between L-big column and the small column, unknown to be measured
By formula (1) as can be known, because D and d are definite values, so
Reduce along with the increase of L.Be arranged on the dial gauge on measuring staff top, can measure the changing value of length L.Thus, the size of cone angle a just can be judged by the size of dial gauge numerical value.
Measuring process of the present utility model is as follows:
One, earlier cubing of the present utility model is placed in the taper hole of standard specimen spare, cover is surveyed in mild and stable more firmly pressing down, and when treating that small column and big column and standard specimen spare endoporus all touch, adjusts dial gauge reading to 0 point then.
Two, then, cubing of the present utility model is moved on the measured piece, measure by above-mentioned identical method, read measured value on dial gauge, be the big column of measured piece and standard specimen spare and the range difference between the small column, this can be converted into angle difference apart from difference.
Three, calculate the angle=standard specimen spare angle+measured value angle of measured piece.
From last surface analysis as can be known, utilize cone angle cubing of the present utility model, can be fast and measure the angle of measured piece accurately.

With reference to Fig. 2, measuring process of the present utility model is as follows:
One, earlier cubing of the present utility model is placed in the taper hole of standard specimen spare 8, cover 4 is surveyed in mild and stable more firmly pressing down, and when treating that small column 12 all touches with big column 11 and standard specimen spare endoporus, adjusts dial gauge 1 reading to 0 point then.
Two, then, cubing of the present utility model is moved on the measured piece, measure by above-mentioned identical method, read measured value on dial gauge, be the big column of measured piece and standard specimen spare and the range difference between the small column, this can be converted into angle difference apart from difference.
Three, calculate the angle=standard specimen spare angle+measured value angle of measured piece.
What should be understood that is: the foregoing description is just to explanation of the present utility model, rather than to restriction of the present utility model, any innovation and creation that do not exceed in the utility model connotation scope all fall within the protection domain of the present utility model.
