Described mandrel is fixed on one end of pull bar by top axle sleeve and not-go-end axle sleeve.
Described not-go-end axle sleeve is removable connection on pull bar.
Described top axle sleeve on pull bar for being fixedly connected with.
Described removable connection is that volution connects.
Described is fixedly connected as welding.
Described handle is the one in disk or pulling buckle.
When described handle is disk, with the connection of pull bar for removably connecting.
Described is detachably connected as 2-8 thread stressed joint.
Described pull bar is greater than the diameter between handle to mandrel not-go-end end face at mandrel not-go-end end face to the diameter of top shaft room.
Compared with prior art, technique effect of the present utility model is embodied in:
By by mandrel, the verifying attachment that forms through the pull bar of mandrel, the handle that is arranged on top axle sleeve on pull bar and not-go-end axle sleeve and pull bar tail end, and then make elongated hole part, especially the checkout procedure in brearing bore footpath avoids traditional inside meter detection, and then make its inspection work complicacy and the cycle is longer, easily occur that the defect of blind spot is resolved, further improve the quality of elongated hole part, improve the qualification rate of product, reduce the working strength of inspection, reduce the production cost of elongated hole part, improve work efficiency.

1-verifying attachment 2-is verified part 11-pull bar 12-not-go-end axle sleeve 13-mandrel 14-top axle sleeve 15-handle 21-inner bore of part.
Embodiment
Below in conjunction with accompanying drawing and concrete embodiment, further restriction is done to the technical solution of the utility model, but claimed scope is not only confined to done description.
Embodiment
As shown in Figure 1 or 2, a kind of internal orifice dimension verifying attachment, by mandrel 13, forms through the pull bar 11 of mandrel 13, the handle 15 that is arranged on top axle sleeve 14 on pull bar 11 and not-go-end axle sleeve 12 and pull bar 1 tail end.
In use, operating personnel hold handle 15 and are interted by internal orifice dimension verifying attachment 1 and be verified in the hole in piece part 21 of part 2, and then controlled by the size of mandrel 13 of endoporus verifying attachment 1 that sets and the difference of the size of top axle sleeve 14, and then make mandrel 13 control to be checked in the profile being verified part and on internal orifice dimension, namely when mandrel 13 does not enter part, and top axle sleeve 14 can by being verified the inside of part 2, and can free shuttling, then inner bore of part footpath size qualification is described; When mandrel 13 through part or can enter part, then illustrate that the aperture dimension of part is defective; When mandrel 13 can not enter part, and top axle sleeve 14 in inside parts free shuttling, can not also illustrate that inner bore of part footpath is defective.
Based on this, make by adopting Coupling bearing internal orifice dimension verifying attachment of the present utility model to reduce the cost of elongated hole internal diameter inspection, proving time shortens, and guarantee that the quality of product is protected, improve the qualification rate of product, avoid in checkout procedure and occur blind spot, make long hole type parts, especially the production efficiency of Coupling bearing internal orifice dimension is improved, and reduces the production cost of part, improves the quality of part.
Mandrel 13 described in the utility model is fixed on one end of pull bar 11 by top axle sleeve 14 and not-go-end axle sleeve 12, and not-go-end axle sleeve 12 is removable connection on pull bar 11, top axle sleeve 14 on pull bar 11 for being fixedly connected with.And then mandrel 13 can be moved freely between top axle sleeve 14 and not-go-end axle sleeve 12, and then ensure that when carrying out piece test, the internal diameter of part can be controlled by the size margin between mandrel 13 and top axle sleeve 14, and then improve the detection efficiency of part internal diameter and the qualification rate of part.
The concrete not-go-end axle sleeve 12 in the utility model is removable connection on pull bar 11 is that volution connects.Make device convenient when carrying out maintenance dismounting and installing, reduce the cost of overhaul of device.
In the utility model top axle sleeve 14 on pull bar 11 for being fixedly connected as welding.Avoid top axle sleeve 14 coming off in the course of the work, improve work efficiency; It also avoid and depart from the course of the work, improve accuracy.
As shown in Figure 3, handle 15 in the utility model is the one in pulling buckle, also can be disk as shown in Figure 1 and Figure 2, when for disk, with the connection of pull bar 11 for removably connecting, this is detachably connected as 2-8 thread stressed joint, and this fastening is that right-angled intersection fastening or disk and pull bar 11 radial edges are around fastening.
As shown in Figure 4, the diameter of pull bar between mandrel 13 not-go-end end face to top axle sleeve 14 is greater than the diameter between handle 15 to mandrel 13 not-go-end end face, and then avoid when testing work, prevent pulling of pull bar 11 excessive, reduce labour intensity, it also avoid not-go-end axle sleeve 12 and can be pulled the skew brought in process, further improve the accuracy of detection, it also avoid equipment due to serviceable life brought built on the sand short, the appearance of the technical matters that maintenance cost is high, and then make internal orifice dimension part testing cost and production cost all lower, improve work efficiency.
Handle 15 of the present utility model can also adopt anti-slip rubber to be made, and also can adopt the outside nested antiskid device of steel plate, meanwhile, soft material also can be adopted to be made.
Pull bar 11 of the present utility model can arrange many places volution, and then improve the universality of elongated hole part.
The internal diameter of mandrel 13 of the present utility model is larger than the diameter of the pull bar 11 between top axle sleeve 14 to not-go-end axle sleeve 12, and arrange on the endoporus of mandrel 13 and help sliding unit, improve in the inspection course of work, pull bar, in the mobility of mandrel 13 inside, reduces working strength.
