Abstract
A hole-to-hole circularity jumping measure relates to step core axis, bracket, screwing cover and percent table. The percent table is fixed on the bracket with tighten screw by screwing cover, the step core axis is also fixed on bracket with tightening screw, and the axial line of measuring head uprights and intersects with the axial line to step core axis. Select suited step core axis according to the trim size of the reference hole to keep step core axis and referenced hole moving in the least clearance, and the measuring head of percent table is pressed on the surface of referenced hole. A handle to bracket operates it to move a circle around the step core axis; the percent table of the bracket indicates the value change, just same as the jumping amount of circle to this hole of the step core axis to the other hole. It is easy and credibility with low cost.
Description
Affiliated technical field
The present invention relates to the measuring appliance of mechanical component position of related features, especially the hole is to circle pulsation measuring tool.
Background technology
The hole of some mechanical component is to the measurement of circle pulsation now, and the best way is to use three-coordinates measuring machine, and measurement result is accurate.But the environment for use of three-coordinates measuring machine is strict, and tested part must be taken the special-purpose place of three-coordinates measuring machine and measure, for complex structure, and the part that quality is big, measurement is got up cumbersome, the measurement expense height.The price of three-coordinates measuring machine is higher at present, and general midget plant should be have more than is needed, more can not be applied to the operation scene.
The purpose of this invention is to provide a kind of easy hole to circle pulsation measuring tool, can be applied directly to the part processing scene, measure convenient and swiftly, accomplish part is monitored effectively, crudy is guaranteed.
The objective of the invention is to realize as follows: measurer by stepped core axle, support, step up cover, dial gauge forms.Dial gauge is fixed on the support by stepping up to apply mechanically holding screw, and stepped core axle also is fixed on the support with holding screw, and the gauge head axial line of dial gauge is vertical with the stepped core axle axial line and crossing.During measurement, the suitable stepped core axle of physical size choosing according to datum hole makes stepped core axle and can be rotated and the gap minimum by datum hole, and the gauge head of dial gauge is pressed in the measured hole surface.Making support by the handgrip on the support is that the center rotates a circle with the stepped core axle, and the numerical value change amount of the dial gauge indication on the support is exactly the circular runout of this hole to the hole at stepped core axle place.Whole measuring process is simple and reliable, the measurer low cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing 1 is the front view of hole to circle pulsation measuring tool, and accompanying drawing 2 is cut-open views that accompanying drawing 1 prolongs A-A.Accompanying drawing 3 is cut-open views that prolong B-B of accompanying drawing 2.
Among the figure: 1, tested part, 2, dial gauge, 3, stepped core axle, 4, handgrip, 5, step up cover, 6, dress table cover, 7, tray deck.
Embodiment
With reference to accompanying drawing, dial gauge 2 is fixed in the hole of dress table cover 6 on the support by stepping up to overlap 5 usefulness holding screws, and the stepped core axle 3 according to the physical size d choosing of the datum hole of tested part 1 is fit to can rotate and the gap minimum stepped core axle 3 and datum hole.The stepped core axle 3 of apolegamy also is fixed in the hole of support upper bracket dish 7 with holding screw.It is H7/f6 that the upper end of stepped core axle 3 cooperates with the hole of tray deck 7, and the part that stepped core axle 3 cooperates with datum hole is pressed the classification of 0.003-0.005 millimeter according to the datum hole dimensional tolerance range.For example: datum hole d is φ 28
0 + 0.021The time, stepped core axle can be made by φ 27.997, φ 28.000, φ 28.003, φ 28.006, φ 28.009, φ 28.012, φ 28.015, φ 28.018, φ 28.021, there is a bit of conelet degree cone the lower end of stepped core axle 3, in order that play guiding function when inserting datum hole.In order to make stepped core axle 3 wear-resistant, the mandrel skin hardness is greater than 52HRC.Support is welded by handgrip 4, dress table cover 6, tray deck 7, dress table cover 6 is welded in the upper surface of tray deck 7, its endoporus axial line is vertical and crossing with the endoporus axial line of tray deck 7, and handgrip 4 is welded in the upper surface of tray deck 7, on the center line vertical with dress table cover 6 endoporus axial lines.Stepping up to overlap 5 is the coaxial opening thin resilient sleeve of inside and outside circle, and local pressure when avoiding clamping dial gauge 2 with holding screw influences the operate as normal of dial gauge 2.The stepped core axle 3 of measurer is contained in the datum hole of tested part 1, and the gauge head of dial gauge 2 is pressed in the measured hole surface.Making support by the handgrip on the support 4 is that the center rotates a circle with stepped core axle 3, by the numerical value change amount of 2 pointers of the dial gauge on support indication, is exactly the circular runout of this hole to the hole at stepped core axle place.General way is: stepped core axle 3 rotates a circle, and finds out the minimum value of dial gauge 2 indications, and the gauge head of dial gauge 2 is parked in this place.Rotate the dial plate of dial gauge 2, make pointer 0, Rotate 180 ° again, the maximal value of directly reading dial gauge 2 indications promptly is a variable quantity, just diameter is that the hole of D is the circular runout of the datum hole of d to diameter.This hole is adapted to especially to circle pulsation measuring tool on the cylinder head of high-power diesel engine, and valve seat orifice is to the measurement of conduit circle pulsation.Accompanying drawing is drawn the conduit circle pulsation measuring tool by measuring the cylinder cover for diesel engine valve seat orifice.Diameter is that the hole of D is a valve seat orifice, wherein adorns valve seat insert.Diameter is that the hole of d is a guide hole, wherein adorns valve guide bushing.The guide rod of the air valve of control diesel engine inlet and outlet partly is contained in the valve guide hole, the cone valve head that is used to seal and the cone match of valve seat insert, want to make the cone match of air valve valve head and valve seat insert tight, at first require valve seat orifice and guide hole that higher right alignment is arranged, also available pores is controlled beating of hole.In the processing of cylinder head, use this measurer to measure the jerk value in hole the hole timely, effectively control the crudy of this operation.Accompanying drawing is drawn by People's Republic of China's mechanical drawing standard, and the matchmark in the literary composition is seen the relevant tolerance fit standard of the People's Republic of China (PRC).
