Description
Technical field
The utility model is related to a kind of clamping screw end face run-out detection devices of automobile gearbox inner fixed bearing.
Background technology
Bearing is one of important part in automobile gearbox, its function is to ensure automobile gearbox internal gear and axis high speed
Rotation, with the development of auto industry, automobile variable speed box structure also continues to optimize design, uses a kind of clamping screw fixing axle
It holds so that automobile gearbox more compact structure, volume smaller, weight is lighter, and clamping screw end face run-out will have a direct impact on axis
Installation accuracy is held, axial motion is caused to lead to bearing initial failure, shortens the service life of bearing.It must be managed in receiving inspection link
Having controlled clamping screw end face run-out this key property size must be in technology claimed range, it is ensured that after clamping screw fixing bearing
The requirement of axial motion is not will produce.Receiving inspection originally uses three coordinates, and gauge head cannot be directly in detecting benchmark screw thread
Sampling site on diameter needs transition detection benchmark to remove detection clamping screw end face run-out, and three coordinate transition detection benchmark also result in
Testing result has error, the problem of being unfavorable for receiving inspection quality control.
Invention content
The purpose of this utility model is to provide a kind of clamping screw end face run-out detection device, overcome original using three seats
The shortcomings that mark transition detection benchmaring result has error, is unfavorable for receiving inspection quality control.
A kind of clamping screw end face run-out detection device, it is characterised in that：Including detection lantern ring and clearance gauge, detect in lantern ring
Hole is designed to threaded hole as detection benchmark, and perpendicular to threaded hole, clamping screw screws in detection lantern ring and tightens, clearance gauge both ends of the surface
Plug is in 0.01-0.2 millimeters of clearance gauges in thickness specification, it is suitable to select between clamping screw end face and detection ferrule end face
The clearance gauge of thickness goes to measure gap between clamping screw end face and detection device end face.The pitch diameter of thread of clamping screw is covered with detection
The threaded hole of ring coordinates, that is, ensure that the pitch diameter of thread of clamping screw as detection benchmark, can fill in clamping screw end face and inspection
The clearance gauge maximum gauge surveyed between device end face is clamping screw end face run-out value.
The utility model has the beneficial effects that：The utility model ensure that the pitch diameter of thread of clamping screw as detection base
It is accurate so that the design basis of clamping screw is consistent with detection benchmark, avoids causing testing result to have error because of transition detection benchmark,
It realizes on-line checking method for product, improves detection efficiency, hold receiving inspection gate of the quality monitoring, prevent clamping screw end face run-out overproof
Axial motion is caused to lead to the quality problems of bearing initial failure.Structure of the detecting device is ingenious in design, good operability, can reach fast
Speed detection clamping screw end face run-out, improves the requirement of detection efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is clamping screw working state schematic representation；
In figure, lantern ring 1, clearance gauge 2, clamping screw 3, bearing 4 are detected.
Specific implementation mode
The embodiment of the utility model structure is described in detail in conjunction with attached drawing：
As shown in Figure 1, a kind of clamping screw end face run-out detection device, it is characterised in that：Including detection lantern ring 1 and clearance gauge
2, for detection 1 bore design of lantern ring at threaded hole as detection benchmark, both ends of the surface screw in detection perpendicular to threaded hole, clamping screw 3
Lantern ring 1 is simultaneously tightened, and the plug of clearance gauge 2 is between 1 end face of 3 end face of clamping screw and detection lantern ring.
The operation principle of the utility model：When detecting 3 end face run-out of clamping screw, clamping screw 3 is first screwed in into detection set
Ring 1 is simultaneously tightened, and is then to select the clearance gauge 2 of suitable thickness to go to measure lock in 0.01~0.2 millimeter of clearance gauge in thickness specification
Gap between tight 1 end face of 3 end face of bolt and detection device, can fill between 1 end face of 3 end face of clamping screw and detection device
2 maximum gauge of clearance gauge is the end face run-out value of clamping screw 3.3 end of on-line checking clamping screw may be implemented in detection lantern ring 1
Face is beated, and is conducive to receiving inspection control product quality, is held receiving inspection gate of the quality monitoring, prevents 3 end face run-out of clamping screw super
Difference causes axial motion to lead to the quality problems of 4 initial failure of bearing.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, make several equivalent substitute or obvious modifications without departing from the concept of the premise utility, and performance or
Purposes is identical, then shall be regarded as belonging to the protection domain that claims that the utility model is submitted determine.
