Abstract
This utility model crankshaft end length detection tool, by beam column (1), the front vee-block bearing (2) for being fixedly connected on beam column (1) front end, the rear vee-block bearing (3) for being fixedly connected on beam column (1) rear end, the dial framework (4) being fixedly connected on front vee-block bearing (2) front end face, the dial gauge (5) being fixedly mounted on dial framework (4), be fixedly connected locating piece (6) on rear vee-block bearing (3) inner side end and constitute.Whether direct measurement crankshaft end length dimension reaches design size requirement, using simple to operate, convenient.
Description
Technical field
The utility model relates to the cubing detected by crankshaft end length, can be with on-line quick detection crankshaft end
Portion's length dimension, judges whether crankshaft end length dimension reaches design requirement, and provides accurate size data for machining.
Background technology
Prior art crankshaft end length detection tool is using the logical of I shape, not-go-end model（Referring to accompanying drawing 1）, the one of model
Side is go side model, i.e. the high limit of size model of crankshaft end Design of length size；The opposite side of model is not-go-end model, i.e., bent
The lower limit model of shaft end Design of length size.
The using method of above-mentioned prior art is：
The first step:Test run is carried out to crankshaft end first and cuts a knife, as long as last process knife festooned vehicle is fallen.
Second step:Test run after cutting leans against go side model A sides at crankshaft end, and opposite side is placed on benchmark trunnion side
Crank arm datum end face on, and make model in axle journal axial line tangent plane on, the parallel promotion model at axial line, if
Model is inserted not enter, then re-start turning to crankshaft end, then reexamine, until model A can insert crankshaft end and base
Till in the crank arm datum end face of quasi- trunnion side.
3rd step：Not-go-end model B sides are leaned against at crankshaft end, opposite side is placed on the crank arm of benchmark trunnion side
On datum end face, and model is made to be on the axial line tangent plane of axle journal, the parallel promotion model at axial line, if model is inserted not
Enter.Illustrate to have reached design size, if can insert, illustrate already less than design size.
Can this detection mode, insert the crank arm datum end face of crankshaft end and benchmark trunnion side by model
Inside judging whether crankshaft end size reaches design requirement, anthropic factor affects that error is larger, and detection accuracy is poor, operates not
It is convenient, and cannot accurate detection crankshaft end length dimension numerical value, it is impossible to cutting is provided for follow-up further machining
The help taken measurements in precision.
Utility model content
The purpose of this utility model is to provide a kind of simple structure, and manufacture is easy, crankshaft end length inspection easy to use
Tool.
This utility model crankshaft end length detection tool by beam column 1, be fixedly connected on 1 front end of beam column front vee-block bearing 2,
The rear vee-block bearing 3 for being fixedly connected on 1 rear end of beam column, the dial framework 4 being fixedly connected on front 2 front end face of vee-block bearing,
The dial gauge 5 being fixedly mounted on dial framework 4, the locating piece 6 being fixedly connected on rear 3 inner side end of vee-block bearing are constituted.
This utility model simple structure, manufacture are easy.
This utility model is first placed it in table using front（Crankshaft end Design of length size）Master body（Ginseng
See accompanying drawing 6）On, front vee-block bearing 2 is placed on front simulation trunnion axle D, rear vee-block bearing 3 is placed on simulation benchmark trunnion
On axle E, locating piece 6 is contacted with the analogue crank arm F datum end faces of simulation benchmark trunnion axle E sides, makes the contact of dial gauge 5
It is pressed on the front end face C of master body, dial gauge 5 is imitated to for 0.
When this utility model is used, place it on main bearing journal, front vee-block bearing 2 and rear vee-block bearing 3 with it is main
Axle journal self-centering is supported, on the outside of locating piece 6 and crank arm（That is benchmark）Face contacts, and then observes the numerical value of dial gauge 5, directly
Measure whether crankshaft end length dimension reaches design size requirement, determine whether to need further machining and cutting
Amount, which uses simple to operate, convenience.

Specific embodiment
This utility model crankshaft end length detection tool by beam column 1, be fixedly connected on 1 front end of beam column front vee-block bearing 2,
The rear vee-block bearing 3 for being fixedly connected on 1 rear end of beam column, the dial framework 4 being fixedly connected on front 2 front end face of vee-block bearing,
The dial gauge 5 being fixedly mounted on dial framework 4, the locating piece 6 being fixedly connected on rear 3 inner side end of vee-block bearing are constituted.
Dial framework 4 is fixedly connected by attachment screw with front 2 front end face of vee-block bearing, and connecting hole and bushing and lock are provided with dial framework 4
Tight screw coordinates fixed installation, locating piece 6 to be fixedly connected by attachment screw with rear vee-block bearing 3 with the table bar of dial gauge.
