Abstract

The utility model provides a measuring instrument for measuring position degree of holes with pattern draft, comprising a measuring instrument base which has the same shape with the end surface of a product; the measuring instrument base is provided with three positioning taper pins; the measuring instrument base is provided with a plurality of holes which correspond to the end surface holes of the product; the holes are internally provided with measuring sleeves which are internally provided with measuring rods; measuring heads designed according to the aperture dimension and the comprehensive tolerance are arranged in front of the measuring rods, wherein the holes for fixing the measuring sleeves on the base, the measuring sleeves, the measuring rods and the measuring heads have the same concentricity; the holes for fixing the measuring sleeves on the base are in interference fit with the measuring sleeves; and the measuring sleeves are in clearance fit with the guide parts of the measuring rods. When in use, the positioning taper pins are used for positioning the end surfaces; the position degree of the product can be measured directly after the measuring rods are inserted in the measuring sleeves; the measuring rods can ensure the position degree of the holes within the depth range of the holes; and compared with the general three-coordinate measuring way, the measuring result is more reliable, the measuring time for complete measurement is only 1 to 3 minutes, the time is shortened greatly, and the resource waste is reduced.

Description

A kind of detection has the measurer of pattern draft hole location
Technical field
The utility model relates to a kind of measurer, specifically is to detect the measurer that has the pattern draft hole location.
Background technology
Because the singularity of aluminium alloy compression casting moulding, the product of all die casts has all designed certain pattern draft, and this just causes cast blank part dimension end size inconsistent, has brought certain degree of difficulty and inconvenience for the process control of part critical size.Commonly used is that three-dimensional detects, but three-dimensional detect be at a certain section and on get three points and look for the center of circle to detect the position, hole, the position degree that can only reflect hole, a certain cross section, and the time of detecting a complex sample needs more than one hour, for the higher die casting industry of automaticity, wasted huge resource beyond doubt, because an alloy product die cast only needs 60-90 second, if add position and detection again that need to adjust, the rising that the time of waste and resource will be at double.
Summary of the invention
The purpose of this utility model be design a kind of simple in structure, easy to use, cheap for manufacturing cost, testing result is intuitive and reliable and the location measurement tool that is easy to judge, specially proposes the measurer that a kind of detection has the pattern draft hole location.
The technical solution of the utility model is for this reason, and a kind of detection has the measurer of pattern draft hole location, comprises the measurer base consistent with the product end surface shape, it is characterized in that: be provided with three location taper pins at the measurer base; The measurer base is provided with a plurality of and hole product end surface hole correspondence, is provided with in the hole to survey cover, surveys in the cover and is provided with measuring staff, and the measuring staff front end is provided with gauge head.
Improvement to such scheme is: fixing hole, survey cover and measuring staff and the gauge head of surveying cover is concentricity on the described base, and wherein fixing hole and the survey cover of surveying cover is interference fit on the base, and the targeting part of surveying cover and measuring staff is a clearance fit.
To being further improving of such scheme: described gauge head designs by aperture size and composite tolerance.
Beneficial effect:
The utility model in use, utilize the location taper pin to carry out the end face location, utilize measuring staff to inject survey cover back and just can directly carry out position degree detection product, measuring staff can guarantee the position degree in hole in the hole depth scope, compare with general three-dimensional detection, testing result has more reliability, only just can all detect with 1-3 minute detection time to finish, and has shortened the time greatly and has reduced the wasting of resources.
The hole of the fixedly survey cover of concentricity, survey cover and measuring staff are when the location measurement tool detects, play the accurate effect in location, then the position, hole is qualified by putting in place fully for measuring staff, detection be the position, hole of hole depth direction, and can reflect the ANOMALOUS VARIATIONS that the position, hole takes place at depth direction; If can not put in place fully, illustrate that then the position, hole becomes curved in depth direction generation skew or hole wall at depth direction, can effectively detect the position degree in hole.The utility model location measurement tool measuring staff designs by aperture size and composite tolerance, with the reliability that guarantees that hole location detects.
That measurer described in the utility model has is simple in structure, easy to use, cheap for manufacturing cost, testing result is intuitive and reliable and be easy to characteristics such as judgement, can effectively detect the position degree in blank hole in the production run fast, effective monitoring blank hole position changes, thereby better control the blank quality, evade the quality of lot problem, for enterprise brings immeasurable economic benefit.Be used to detect the position degree that has the pattern draft hole on the die casting, this technology is applicable to that the position degree that has the pattern draft hole on all cast blank spares detects.

Embodiment
Shown in Fig. 1, Fig. 2 a, Fig. 2 b, Fig. 3 a, Fig. 3 b,
1 is the measurer base among the figure, the 2nd, and the location taper pin, the 3rd, the hole of product end surface hole correspondence, the 4th, survey cover, the 5th, measuring staff, the 6th, measuring staff targeting part, the 7th, gauge head, the 8th, product.
It is as follows to further describe the utility model:
Be provided with three location taper pins 2 at measurer base 1; Measurer base 1 is provided with a plurality of and hole 3 product end surface hole correspondence, is provided with in the hole 3 to survey cover 4, surveys in the cover 4 and is provided with measuring staff 5, is provided with gauge head 7 before the measuring staff 5.
The fixing hole 3 of surveying cover on the base, survey cover 4 and measuring staff 5 is concentricitys, surveying cover 4 is in the hole 3 that is set on the base plate 1, and the targeting part 6 of surveying cover 4 and measuring staff 5 is clearance fit.
Gauge head 7 designs by aperture size and composite tolerance.
The design and produce profile and the position, hole of depending on detected foundry goods of measurer body distributes in the concrete use, register pin can adopt floating structure or taper pin to carry out grinding-in in the positioning reference hole, the size and the composite tolerance requirement of detected element are depended in the design of surveying cover, measuring staff, measuring staff designs by aperture size and composite tolerance, can guarantee the position degree in hole in the hole depth scope.For example, detected element aperture is Tolerance of Degree of position is ¢ 0.7, and then composite tolerance is 1.2, looks into size and tolerance and wear limit that the relevant design standard can obtain the test section, and the test section is of a size of Wear limit ¢ 9.947, and the test section degree of depth determines that by hole depth targeting part basic size is got ¢ 13.5, and the position of then leading is of a size of ¢ Wear limit ¢ 13.479, survey cover and are of a size of Wear limit ¢ 13.524.
Using method:
After part is placed and steadily is placed on the product 8, utilize three locating cone finger settings, vertically insert measuring staff in the measured hole, measuring staff smoothly by and can put in place fully, then the position, hole is qualified, if can not put in place fully, illustrate that then the position, hole becomes curved in depth direction generation skew or hole wall at depth direction, then the position, hole is defective.
