Description

A kind of inner hole center degree cubing

Technical field

The utility model relates to cubing technical fields, more particularly to a kind of inner hole center degree cubing.

Background technique

Since center support class product is fixed or is supported on the basis of the central bore of product, to center branch There are strict requirements in the position of seat class product center inner hole, and product inner hole need to be guaranteed at the center of its shape.But due to center Support class product shape is complicated, irregularly, come the position of inspection center's inner hole by the way of crossing by hand, detects a product At least with a hour, and product quantity to be detected is more, and working efficiency is low, and measurement inaccuracy, there are biggish errors. If detected using three-coordinates measuring machine, although available more accurately as a result, since three-coordinates measuring machine accounts for Ground area is larger, the reason high to environmental requirement, be generally placed in the sensing chamber of constant temperature do sampling observation use, can not full inspection, and also There is the problems such as cumbersome, low efficiency, at high cost.It is a kind of for measuring center support class product center therefore, it is necessary to design The cubing of inner hole center degree can not only accurately measure shape complex product inner hole center degree, and Want easy to operate, quick, use cost is low.

Utility model content

The purpose of this utility model is that in view of the deficiencies of the prior art, and a kind of inner hole center degree cubing is provided, Its is easy to use, can accurately be measured shape complex product inner hole center degree, and want easy to operate, quick, Use cost is low, improves working efficiency.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of inner hole center degree cubing, packet The mandrel for including thin plate, being put into product center inner hole to be measured, the mandrel is fixedly connected by connecting rod with the thin plate, described Perforative sample hole, the shapes and sizes in the sample hole and the product shape to be measured are provided in the middle part of thin plate to identical, the core Axis center axis and sample hole central axis coaxial.

Further, after the mandrel is put into the product center inner hole to be measured, the mandrel outer surface and the production to be measured Gap between product inner hole is 0.1-0.2mm.

Further, one end that the connecting rod is connect with the thin plate is provided with connecting hole, and the connecting hole is kidney ellipsoid.

Further, the connecting rod is 3-5 root.

The beneficial effects of the utility model are: a kind of inner hole center degree cubing, including thin plate, production to be measured can be put into The mandrel of product central bore, the mandrel are fixedly connected by connecting rod with the thin plate, are provided in the middle part of the thin plate perforative Sample hole, the shapes and sizes in the sample hole and the product shape to be measured are to coincideing, the mandrel central axis and the sample hole Central axis coaxial.When measurement, thin plate is placed on center support class product shape profile exterior, mandrel is put into product center inner hole In, if mandrel outer surface is consistent with the gap of inner hole inner wall, center support class product center inner hole at the center of product shape, Hole location is qualified i.e. in product center, on the contrary then unqualified.The utility model structure is simple, easy to use, greatly improves work Make efficiency, reduces production cost.

Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments, is not that this is practical Novel practical range limited to this.

As shown in Figure 1, a kind of inner hole center degree cubing of the present embodiment, measurement panel thin plate 1, can be put into it is to be measured The mandrel 2 of product center inner hole, the mandrel 2 are fixedly connected with the thin plate 1 by connecting rod 3, are provided in the middle part of the thin plate 1 Perforative sample hole 11, the shapes and sizes in the sample hole 11 and the product shape to be measured are to coincideing, i.e., the shape of product to be measured Profile can be put into sample hole 11, and 11 inner wall of sample hole is made to be in contact with contour edge, be conducive to reduce detection error, the mandrel 2 central axis and 11 central axis coaxial of sample hole.

When measurement, by 1 set of thin plate on center support class appearance profile, mandrel 2 is inserted into the central bore of product to be measured, If the gap between the outer surface of mandrel 2 and the inner wall of product center inner hole to be measured is consistent, and measured panel can freely be fallen, Product center inner hole then be can guarantee at the center of product shape, i.e., hole location is qualified in product center, and on the contrary then product does not conform to Lattice.

After the mandrel 2 is put into the product center inner hole to be measured, 2 outer surface of mandrel and the product inner hole to be measured Between gap be 0.1-0.2mm, convenient for judging the gap between the outer surface of mandrel 2 and the inner wall of product center inner hole to be measured It is whether consistent.

One end that the connecting rod 3 is connect with the thin plate 1 is provided with connecting hole 31, and the connecting hole 31 is kidney ellipsoid, Facilitate adjusting connecting rod, the central axis of mandrel 2 is made to be located at the center in the sample hole 11 of thin plate 1.

The connecting rod 3 is 3-5 root, firmly fixed with thin plate 1 convenient for mandrel 2, prevents mandrel 2 from shifting, influences The accuracy of measurement.

Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this The spirit and scope of utility model technical solution.
