Abstract
The utility model discloses a device for detecting the position degree of a crankshaft flange hole. The device comprises a detector body, a fixed positioning pin and a plurality of movable positioning pins, wherein the detector body has a concave circular structure; the plurality of movable positioning pin holes which correspond to a position of the crankshaft flange hole to be checked and are positioned on the same circumference are uniformly formed in the middle inwards concave annular part of the detector body; a fixed positioning pin hole is also formed; and the fixed positioning pin hole and the movable positioning pin holes are formed based on the position degree referring to an inwards concave circular face and an inwards concave cylindrical face according to a geometrical tolerance level corresponding to the crankshaft flange hole to be checked. A through hole is formed in the center of the detector body and in transitional fit with a rear crankshaft flange. The device for detecting the position degree of the crankshaft flange hole has a simple structure, is convenient to use, and can be used for quickly detecting the position degree of the crankshaft flange hole; and the detection result is accurate and reliable.
Description
Technical field
The utility model relates to a kind of device that crankshaft flange hole site degree detects that is used for.
Background technology
In the commercial production, strict position degree requirement is arranged between flange hole of crankshaft.When detecting hole location, all adopt general measurer usually, bent axle is placed on the V-block, decide a datum hole earlier, and then calculate the coordinate in other relative datum holes, center, hole, another measures in the hole.Testing process is pretty troublesome, and work efficiency is very low, and can't guarantee that testing result is accurate.And produce therefore unusual needs of the current crankshaft flange of incompatibility hole site degree testing of this detection method in the commercial production often in batches.
The utility model content
For overcoming the deficiency on the prior art, it is a kind of simple in structure, easy to use that the purpose of the utility model is to provide, the reliable crankshaft flange of detection efficiency height and testing result hole site degree pick-up unit.
In order to realize the purpose of the utility model, the technical scheme of the utility model is following:
A kind of crankshaft flange hole site degree pick-up unit; Comprise cubing body, fixed locating stud and a plurality of loose pin; It is characterized in that; Inspection is specially the spill circular ring structure, and middle indent annular section evenly is provided with a plurality of corresponding with the crankshaft flange hole sites that need to check and be in the activity orientation pin-and-hole on the same circumference, and other is provided with a stationary positioned pin-and-hole; The center of cubing body has a through hole.
Stationary positioned pin-and-hole and activity orientation pin-and-hole are the position degree of benchmark with the indent anchor ring and the indent face of cylinder, and the corresponding form and position tolerance grade of flange hole of crankshaft of inspection is provided with as required.
Between through hole and the back crankshaft flange is transition fit.
The stationary positioned pin-and-hole is positioned in the middle of any adjacent 2 activity orientation pin-and-holes, and the center of stationary positioned pin-and-hole and activity orientation pin-and-hole is on the same circumference.
The utility model is provided with the stationary positioned pin-and-hole and the activity orientation pin-and-hole of position degree requirement through the cubing body; The use of matching and fixing register pin and loose pin; Whether the position degree that can fast detecting goes out flange hole of crankshaft meets the requirements; Improve testing efficient greatly, also guaranteed the detection quality simultaneously.

Fig. 2 is the structural representation of cubing body;
Fig. 3 is the structural representation of fixed locating stud;
Fig. 4 is the structural representation of loose pin.
Among the figure, 1, cubing body 2, fixed locating stud 3, loose pin 4, stationary positioned pin-and-hole 5, activity orientation pin-and-hole 6, through hole.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.
As shown in Figure 1, the utility model includes cubing body 1, fixed locating stud 2 and a plurality of loose pin 3, and cubing body 1 is the spill circular ring structure, and the center of cubing body 1 has a through hole 6.
As shown in Figure 2, the indent annular section evenly is provided with a plurality of correspondingly with the crankshaft flange hole sites that need to check and be in the activity orientation pin-and-hole 5 on the same circumference in the middle of the cubing body 1, and other is provided with a stationary positioned pin-and-hole 4; Stationary positioned pin-and-hole 4 is positioned in the middle of 2 adjacent arbitrarily activity orientation pin-and-holes 5, and the center of stationary positioned pin-and-hole 4 and activity orientation pin-and-hole 5 is on the same circumference.
Like Fig. 3,4 is respectively the structural representation of fixed locating stud 2 and loose pin 3.
The processing request of the utility model is:
1, stationary positioned pin-and-hole 4 and activity orientation pin-and-hole 5 are the position degree of benchmark with the indent anchor ring and the indent face of cylinder, and the corresponding form and position tolerance grade of flange hole of crankshaft of inspection is provided with as required.
2, be transition fit between through hole 6 and the back crankshaft flange.
Concrete detection method is:
Be buckled in cubing body 1 on the crankshaft flange of back, cubing body 1 is a transition fit with the back crankshaft flange, is fixed on cubing body 1 on the crankshaft flange with the fixed locating stud on the cubing body 12.
Be placed on bent axle on two V shape irons on the dedicated platform then, it is equally high to detect crankshaft two end with dial gauge, and then measures first connecting rod diameter of axle center line and spindle centerline all on a horizontal plane with dial gauge.
At last eight loose pins 3 are inserted in the flange hole of crankshaft, measure the position degree of threaded hole one by one.So not only accelerated detection speed, also improved accuracy, it is very convenient that the checker is detected, and improved work efficiency.
Those skilled in the art should be understood that the utility model can realize through other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the utility model all comprised by the utility model.
