Currently, being applied to the forging press of all kinds of die forging industries, the mold core used when forging circular contour part is generally put It sets and is fixed in the inner hole of upper and lower blind hole device, protected by controlling inner circle size and the coaxiality deviation of upper and lower blind hole device Demonstrate,prove the exact position of upper and lower mold core.The inner circle size of blind hole is controlled very well by machining means, but works as upper and lower blind hole device When being individually fixed in upper and lower two sides and need to guarantee circle concentricity in upper and lower, due to parts machining and accumulated error when assembled Presence, cause in upper and lower that there are deviations for circle concentricity, since upper and lower blind hole device has been fixed respectively at this time, space bit therebetween Set narrow, common roundness measuring equipment, three coordinate measurement machines are difficult to carry out data acquisition, and it is always one that how this deviation, which accurately detects, A problem.General means are to forge the outer profile surplus of part blank by increasing and offset this deviation, or by forging The separate-blas estimation of part blank calculates the coaxiality deviation of upper and lower inner circle, according to calculated value adjusts upper and lower blind hole fixture Relative position come the concentricity that is needed.Upper two methods first is that increase part blank surplus, can cause blank cost and The increase of processing cost, another then need test of many times to forge, adjust the relative position of upper and lower blind hole fixture, consumptive material is time-consuming Effort.
CN108592733A discloses a kind of flight stability wing assemble welding tolerance detection device, the lower end of measuring rod bracket It is installed in the central blind hole of column, measuring rod bracket is affixed by swivel nut and column, upper measuring rod, positioning measurement bar and lower survey Gauge rod is from top to bottom sequentially arranged on the corresponding circular through hole of measuring rod bracket, on the front end face of measuring rod bracket along its length Direction is machined with scale observation slot, and groove is used to observe the Measurement scales line of measuring rod, positioning measurement bar and lower measuring rod, on Measuring block, horizontal processing on the measuring block of upper measuring rod are provided on the same end of measuring rod, positioning measurement bar and lower measuring rod There is height tolerance detection slot, corresponds to and be machined with along the vertical direction on the measuring block of upper measuring rod, positioning measurement bar and lower measuring rod Vertical tolerance detection slot.
Summary of the invention
The purpose of this utility model is to be directed to above-mentioned status, it is desirable to provide a kind of structure is simple, easy to carry, is easy to grasp Make, data are directly read, and measurement accuracy is reliable, are applicable to various similar structures, and different size inner circle is coaxial up and down blind The measuring device of hole inner circle coaxiality deviation.
The implementation of the utility model aim is to detect the measuring device of coaxial blind hole inner circle coaxiality deviation up and down, It is made of adjustable reference flat component and the dial gauge with adsorption support;
Sliding slot is provided on the benchmark plate of the adjustable reference flat component, sliding screw pulley bearings component is placed in strip In logical sliding slot, in the symmetric position that strip leads to sliding slot center line two sides, fixed there are two determine screw pulley bearing assembly;The cunning It moves screw pulley bearing assembly and determines screw pulley bearing assembly and be made of screw pulley bearing and its outer nut;Bearing Screw rod end is screwed on nut;
There is take-up on the adsorption support of the dial gauge component with adsorption support, fills dial gauge on take-up.
When measurement, adjustable reference flat component is placed on lower blind hole inner hole wall, makes two to determine screw pulley bearing assembly, cunning Dynamic screw pulley bearing assembly is adjusted to the tangent position with lower blind hole inner hole wall and fastens positioning.By the percentage with adsorption support Table component is fixed on the empty place of adjustable reference flat component, adjusts dial gauge by knob take-up and properly measures height, Carry out data calibration.Rotation adjustable reference flat component drives dial gauge to rotate in upper blind hole, detects that bounce everywhere is inclined Difference value, thus value finds out coaxial blind hole inner circle coaxiality deviation up and down.
The utility model solves the problems, such as detection, and coaxial blind hole device inner circle coaxiality deviation is difficult up and down, structure letter It is single, it is convenient for carrying, easily operated, data can be directly read, and measurement accuracy is reliable, not only be avoided that increase forges the outer of blank Profile allowance reduces blank material cost, processing cost, moreover it is possible to remove the work that testpieces forges detection, reduce material, artificial Cost.
The utility model can be suitably used for the upper and lower concentricity detection of different inner hole size devices, improve Product Precision and life Produce efficiency.
