Description

A kind of taper hole process redundancy is measured measurer

Technical field

The utility model technology belongs to detection range and uses new technique, relates generally to a kind of taper hole process redundancy and measures measurer.

Background technology

Taper hole is the common a kind of structure of revolving body workpieces, and it has higher right alignment, cooperates self-locking performance good, good airproof performance, and gap and interference such as can freely adjust at advantage, extensively employing in many fit structures.During the turning taper hole, the process redundancy measurement of taper hole is got up cumbersome on engine lathe, generally all is to adopt measurer such as vernier caliper to record taper hole outside diameter, end diameter and cone length equidimension respectively, tries to achieve by calculating again; Also having a kind of method is to adopt taper plug gauge, feeler gauge is made according to workpiece taper hole outside diameter and taper value, need constantly it to be filled in the machining hole to detect during the processing taper hole, by the fuzzy lathe tool radial feeds of adjusting of experience, be in same plane up to big end group face of feeler gauge and workpiece end face, can think that taper hole processing meets the requirements, this detection method is by operative employee's experience fuzzy judgement, be difficult to accurately realize the detection processing of taper hole, first method is in production in enormous quantities, use very inconveniently, need regular measurements and calculations, second method is to operative employee's experience, operative skill is had relatively high expectations.

Summary of the invention

The purpose of this utility model is to propose a kind of taper hole process redundancy to measure measurer.In the taper hole process, can realize detection fast, and have simple in structurely that make easily, easy to use, measured value is directly perceived, the characteristics that precision is higher to taper hole process redundancy.

The utility model realizes that the technical scheme that above-mentioned purpose is taked is: it mainly is made up of taper plug gauge, tetragonal body chi frame, trip frame and vernier caliper, and taper plug gauge is "T"-shaped structure, is processed with mounting hole at its horizontal cylinder rear portion; The upper end of tetragonal body chi frame is provided with the mounting hole socket connection on cylinder register pin and the taper plug gauge, and the bottom on tetragonal body chi frame is provided with the trip frame, and this trip frame is provided with chute, and vernier caliper also can slide along it with the chute socket connection on the trip frame.

The utility model is mainly used in when the lathe turning taper hole, the accurate measurement of process redundancy.Have simple in structurely, make easily, easy to use, measured value is directly perceived, and the characteristics that precision is higher can realize the detection of taper hole process redundancy fast, for processing the condition that taper hole is provided convenience efficiently, accurately, playing preferably in the taper hole process, process redundancy detects effect.

Embodiment

In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:

Fig. 1 is in conjunction with shown in Figure 2, and present embodiment mainly is made up of taper plug gauge 1, tetragonal body chi frame 2, trip frame 3, vernier caliper 4, trip bolt 5.Taper plug gauge 1 can be sized to series according to different taper holes, to satisfy different size size taper hole in-process measurement needs.Taper plug gauge 1 is "T"-shaped shape, is processed with the hole that is connected with tetragonal body chi frame 2 at its horizontal cylinder rear portion.The upper end of tetragonal body chi frame 2 is provided with the hole socket connection on cylinder register pin and the taper plug gauge 1, it is fixedly connected by trip bolt 5 that bottom on tetragonal body chi frame 2 is provided with trip frame 3, be provided with chute on trip frame 3, vernier caliper 4 also can slide along it with the chute socket connection on the trip frame 3.Taper plug gauge 1 adopts 45 steel or 40Cr material, grinding after heat treatment forms, make it have high dimension precision, the accuracy of form and position and certain wearing quality, effectively guaranteed the manufacturing accuracy of the tetragonal body and the taper plug gauge basal plane binding face of tetragonal body chi frame, to guarantee the accuracy of detection of this testing tool.

When present embodiment uses, as shown in Figure 3, earlier the taper plug gauge on the test measuring device 1 is inserted in the workpiece taper hole, both are fitted by the conical surface fully, promote the vernier caliper blade then and measure workpiece end face and taper plug gauge basal plane distance A value in the diagram, just can calculate the remaining processing allowance value of taper hole rapidly, reasonably arrange the lathe tool radial feeds, just can fast taper hole be worked into and require size according to this processing allowance value.Its concrete computing method and principle are: at first calculate according to following formula 1, then process redundancy Δ d is on the diameter of work:

$\mathrm{\Δd}=A\·2\tan \frac{\mathrm{\α}}{2}$ (formula 1)

Δ d in the formula---process redundancy on the diameter of work (mm)

A---workpiece end face and taper plug gauge basal plane distance (mm)

α---workpiece coning angle

Then workpiece tapering C value is calculated according to formula 2

$C=2\tan \frac{\mathrm{\α}}{2}$ (formula 2)

C in the formula---workpiece tapering

Then can release process redundancy Δ d computing formula 3 on the diameter of work

Δ d=AC (formula 3)

Promptly can rapidly, accurately calculate the process redundancy of taper hole according to above-mentioned rational formula, for the accurate measurement of taper hole process redundancy provides means.
