Abstract
A kind of cubing of the utility model, it is made of inner prop, measurement column, holding screw and matrix, the centralized positioning column of measured workpiece is inserted into the centre bore of matrix when use, each screw is also inserted into each hole around matrix center hole respectively simultaneously, and the lower end surface of measured workpiece is bonded completely with the upper surface of matrix；The bottom-up major diameter fit for making its inner hole Yu each screw of measurement column；If the upper surface of each measurement column changeover portion can be bonded completely with matrix lower end surface, illustrate that the position degree of each screw is qualified；After the position measurement of each screw is qualified, if the lower end surface of inner prop is also among the step of measuring section lower end of measurement column, the height for being tested screw is qualified.The utility model can not only measure the position degree after HUB rigging screw in use, and can measure the assembly height of each screw.
Description
Technical field
The utility model relates to a kind of cubing, specifically a kind of position degree that can be measured after HUB rigging screw with
And the cubing of screw height.
Background technique
In the drive mechanism of automobile chassis, HUB is the important part with brake disc and transmission axis connection, use process
In be pressed screw in general each hole first on it；In order to guarantee the smooth assembly of HUB Yu other parts, generally press fitting screw
Need to detect the position degree of each screw and the height of each screw afterwards.Currently, generallyd use in industry three coordinate pairs the two
Parameter measures, and measurement efficiency is very low.Therefore, it is necessary to a kind of cubings can substitute three coordinates, complete the inspection of the above project
It surveys.
Summary of the invention
The purpose of this utility model is to provide for a kind of cubing, the position degree after can not only measuring HUB rigging screw, and
And the assembly height of each screw can be measured.
To achieve the goals above, the technical solution of the utility model is: a kind of cubing, by inner prop, measurement column, lower tightening
Screw, upper holding screw and matrix are formed, and the outside of inner prop and the inner hole of measurement column, fit clearance are less than
0.01mm；Lower holding screw is fixed on measurement column, and top is matched with the open slot of inner prop；The guide section and base of measurement column
Hole on body matches, and fit clearance is less than 0.01mm；Upper holding screw is fixed on matrix, top and opening on measurement column
Mouth slot matches.
The centralized positioning column of centre bore and measured workpiece among matrix cooperates；There are several circles around the centre bore of matrix
The equally distributed hole of circumferential direction, this some holes cooperate with the guide section of measurement column respectively.
Measurement column includes: measuring section, changeover portion and guide section；Measuring section is in the lower end of changeover portion, and guide section is in transition
The upper end of section；The lower end of measuring section is stepped ramp type, even if the height tolerance value of step height element to be measured；Measuring section lower end inner hole
Edge keep wedge angle；The edge of inner prop lower end also keeps wedge angle.
In actual use, the centralized positioning column of measured workpiece is inserted into the centre bore of matrix, while each screw
It is inserted into each hole around matrix center hole respectively, and the lower end surface of measured workpiece is bonded completely with the upper surface of matrix；
The bottom-up major diameter fit for making its inner hole Yu each screw of measurement column；If upper surface and the matrix of each measurement column changeover portion
Lower end surface can be bonded completely, illustrate that the position degree of each screw is qualified；After the position measurement of each screw is qualified, if interior
The lower end surface of column is also among the step of measuring section lower end of measurement column, then the height for being tested screw is qualified.
The utility model can not only measure the position degree after HUB rigging screw in use, and can measure each
The assembly height of screw；Meanwhile having structure simple, the features such as detection accuracy is high, easy to use, low manufacture cost.

Specific embodiment
With reference to the accompanying drawing illustrate according to the utility model proposes specific device details and working condition.
The device is made of inner prop 1, measurement column 2, lower holding screw 3, upper holding screw 4 and matrix 5, inner prop 1
The inner hole in outside and measurement column 2, fit clearance are less than 0.01mm；Lower holding screw 3 is fixed on measurement column 2, top
It is matched with the open slot of inner prop 1；The guide section 23 of measurement column 2 is matched with the hole on matrix 5, and fit clearance is less than
0.01mm；Upper holding screw 4 is fixed on matrix 5, and top is matched with the open slot on measurement column 2.
The centralized positioning column of centre bore and measured workpiece among matrix 5 cooperates；There are several around the centre bore of matrix 5
The equally distributed hole of circumferencial direction, this some holes cooperate with the guide section 23 of measurement column 2 respectively.
Measurement column 2 includes: that measuring section 21, changeover portion 22 and guide section 23 are formed；Measuring section 21 is in changeover portion 22
Lower end, guide section 23 is in the upper end of changeover portion 22；The lower end of measuring section 21 is stepped ramp type, even if the height of step height element to be measured
Spend tolerance value；The edge of 21 lower end inner hole of measuring section keeps wedge angle；The edge of 1 lower end of inner prop also keeps wedge angle.
During the work time, the centralized positioning column of measured workpiece is inserted into the centre bore of matrix 5, while each screw
Also it is inserted into each hole around 5 centre bore of matrix respectively, and the lower end surface of measured workpiece and the upper surface of matrix 5 are pasted completely
It closes；The bottom-up major diameter fit for making its inner hole Yu each screw of measurement column 2；If the upper end of each 2 changeover portion 22 of measurement column
Face can be bonded completely with 5 lower end surface of matrix, illustrate that the position degree of each screw is qualified；The position measurement of each screw is qualified
Afterwards, if the lower end surface of inner prop 1 is also among the step of 21 lower end of measuring section of measurement column 2, the height for being tested screw is closed
Lattice.
