Abstract

The invention relates to a special-purpose testing fixture of a crankshaft measurement long shaft external diameter and transverse plane jumping value and a shaft end distance. The testing fixture is composed of a testing fixture main body and an indicating gauge. The testing fixture is characterized in that: the testing fixture main body is formed by a pedestal and a locating piece which is fixedly installed on the pedestal, the locating piece is provided with a detection through hole inside, and one end of the locating piece is provided with a shaft end distance detection indicating gauge in a coaxial arrangement mode; the other end of the locating piece is installed with a jumping value detection indicating gauge. The testing fixture has the advantages of simple structure, reasonable design, simple operation, and accurate measurement, detection efficiency of the crankshaft measurement long shaft external diameter and transverse plane jumping value and the shaft end distance are greatly raised, compared with a traditional measurement mode, the detection efficiency is raised by 8 to 10 times, thus production efficiency is effectively raised, and production quality is raised simultaneously.

Description

Bent axle is surveyed major axis external diameter and face runout value and axle head apart from appliance special for detecting
Technical field
The present invention relates to the cubing of field of machining, particularly a kind of bent axle is surveyed major axis external diameter and face runout value and axle head apart from appliance special for detecting.
Background technology
For axial workpiece, like the bent axle major axis of PL/BD h type engine h, owing to need to guarantee major axis external diameter and the beating degree that belongs to the side crankshaft end-face, and the distance of crankshaft end-face to major axis axle head, the two detects therefore to need this.Existing metering system need adopt unit clamp, and measurers such as table, chi cooperate and could accomplish, and has apparatus complicacy, problem that input cost is high; And, also have measuring operation loaded down with trivial details, measure difficulty, the time is long, the low deficiency that waits of efficient influences the production efficiency and the quality of production.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of reasonable in design, simple to operate, measure accurately bent axle and survey major axis external diameter and face runout value and axle head apart from appliance special for detecting.
The present invention solves its technical matters and realizes through following technical scheme:
A kind of bent axle is surveyed major axis external diameter and face runout value and axle head apart from appliance special for detecting; Constitute by cubing main body and dial gauge; It is characterized in that: the cubing main body is made up of base and the locating piece that is installed on this base; Be shaped on the detection through hole in locating piece inside, leave at the coaxial installation shaft end distance of an end of locating piece and detect dial gauge; The other end at locating piece is equipped with beating degree detection dial gauge.
And the gauge head that said beating degree detects dial gauge is oblique gauge head.
Advantage of the present invention and beneficial effect are:
The present invention is simple in structure, reasonable in design, easy and simple to handle, measurement is accurate; Can significantly improve bent axle is surveyed major axis external diameter and face runout value and axle head distance detection efficient; Improve 8-10 doubly than the traditional measurement mode, thereby effectively enhance productivity, improve the quality of production simultaneously.
Description of drawings
Fig. 1 is structural representation of the present invention (operation chart).
Embodiment
Through specific embodiment the present invention is made further detailed description below, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of bent axle is surveyed major axis external diameter and face runout value and axle head apart from appliance special for detecting; Constitute by cubing main body and dial gauge; Its innovation part is: the cubing main body is made up of base 2 and the locating piece 3 that is installed in base upper surface; Be shaped on detection through hole 4 in locating piece inside, from detecting dial gauge 1, it is inner that the gauge head of this axle head distance detecting dial gauge is threaded onto the made detection hole of locating piece at the coaxial installation shaft end distance of an end of locating piece.The other end at locating piece is equipped with beating degree detection dial gauge 6, and the gauge head that this beating degree detects dial gauge is oblique gauge head, and it can contact on the tested end face of bent axle main body.
Use-pattern of the present invention is:
During measurement bent axle 5 is fixed on the locating piece of cubing main body on request, rotary crankshaft can confirm that by beating degree dial gauge reading major axis external diameter and major axis belong to the jitter values of side bent axle main body end face.Measure between major axis axle head and the bent axle main body end face apart from the time, move bent axle, make the reading of beating degree dial gauge be shown as zero, axle head is the axle head distance apart from the numerical value that dial gauge showed at this moment.

Claims (2)
