Description
Technical field
The present invention relates to a kind of devices for mechanical product quality detection, in particular it relates to which one kind is used for
The detection device of quantitative measurment differential assembly sideshake.
Background technology
Differential mechanism is the important component in car transmissions, it is by a pair of of axle shaft gear and a pair of of planetary gear set
At two influence mating vehicle transmission quality to the meshing quality of gear.Mating engagement gear is entirely located in envelope in differential assembly
It in the shell closed, can not directly implement the measurement of gear meshing quality, can only judge gear meshing quality by measuring sideshake.It can
Be, commercially available general amount cubing can not quantitative measurment differential assembly sideshake.Currently, the industry, which can only be used, measures turning for semiaxis
Dynamic gap is measured instead of sideshake, and the sideshake size of qualitative differential assembly is carried out with this.Because the prior art lacks effective detection dress
It sets, cannot take out accurate quantitative data, so qualitative detection sideshake can not really reflect differential assembly quality, this situation is not
Conducive in production process technique sustained improvement implement.
Invention content
It the problem of cannot quantifying detection differential assembly sideshake present invention is generally directed to commercially available general amount cubing, proposes a kind of
Simple in structure, accurate positioning measures convenient, the differential assembly sideshake detection device of direct quantitative display measurement result.
The present invention is achieved through the following technical solutions technical goal.
Differential assembly sideshake detection device, it includes dial gauge, dial framework, upper semiaxis, wrench, nut, screw rod, lower semiaxis
And pedestal.Plane is fixedly connected with the lower semiaxis being vertically arranged upward on the pedestal, and the one end of lower semiaxis upward is external splines shaft part,
On pedestal two screw rods being vertically arranged are connected by differential assembly installation site hole to be detected.The dial framework is rod piece, is vertically arranged
Dial framework is connected on pedestal side by side with screw rod, and dial gauge is laterally inserted at the center of dial framework top, is located at the to be checked of dial gauge lower part
Differential assembly is surveyed after the positioning of lower semiaxis again by two Screw rod bearings, it is total that nut with screw rod locks differential mechanism to be detected
At.It is theed improvement is that：Upper semiaxis is inserted in installation differential assembly to be detected in place upward endoporus.The upper semiaxis
It is the short axle that is vertically arranged that a kind of side has flattened arm, one end directed downwardly is external splines shaft part, and one end upward is rectangle tenon, flattened
The cantilever end of arm is leaned on to dial indicator measuring head.The wrench is coordinated by the rectangle tenon of built-in rectangular and upper semiaxis, clockwise
Rotation wrench, which then links, goes up semiaxis, constitutes differential assembly built-in gear to be detected and measures sideshake structure under location condition.
As the scheme that is further improved, the dial framework is located on the outside of the screw rod of side, in dial framework center line and differential mechanism to be checked
Heart line spacing is definite value A.
As the scheme that is further improved, lower semiaxis is identical with the male splined shaft segment structure parameter of upper semiaxis, directly and differential
Axle shaft gear built in device coordinates.
As the scheme that is further improved, the dial framework is the rod piece that cross section is rectangle.
Compared with prior art, the present invention having the positive effect that：
1, make the measurement of differential assembly sideshake under location condition, fixed and positioned simple in structure, detection method is easy, and
And have no special requirements to testing conditions, it is suitble to production scene mating；
2, quantify testing result, detection efficiency is high；
3, it is converted just through simple by dial gauge indicating value, the indicating value after the flattened arm of upper semiaxis amplifies the micro sideshake measured
Practical backlash values can be obtained, since testing result is objective, accuracy of detection is high.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the vertical view of Fig. 1.
Specific implementation mode
Below according to attached drawing and in conjunction with the embodiments, the invention will be further described.
Fig. 1 and differential assembly sideshake detection device shown in Fig. 2, it includes dial gauge 1, dial framework 2, upper semiaxis 3, wrench
4, nut 5, screw rod 6, lower semiaxis 7 and pedestal 8.The pedestal 8 is one block of plate, it is disposed as the basic part of this detection device
Plane is fixedly connected with the lower semiaxis 7 being vertically arranged upward on the bottom, pedestal 8, and the one end of lower semiaxis 7 upward is external splines shaft part,
On pedestal 8 two screw rods 6 being vertically arranged are connected by differential assembly installation site to be detected hole.The dial framework 2 is in for cross section
The rod piece of rectangle, the dial framework 2 being vertically arranged and screw rod 6 are connected to side by side on pedestal 8, in the present embodiment 2 longitudinal center line of dial framework with it is poor
Fast device centreline space laterally inserts dial gauge 1 away from A=150mm at 2 top axial center of dial framework.It is in 1 bottom of dial gauge
Differential assembly to be detected is supported by two contour screw rods 6 again after the positioning of lower semiaxis 7, and nut 5 is locked with screw rod 6
Differential assembly to be detected.Upper semiaxis 3 is inserted in installation differential assembly in place upward endoporus, upper semiaxis 3 is one kind one
Side has the short axle that is vertically arranged of flattened arm 3.1, and one end directed downwardly is external splines shaft part, and the external splines shaft part at this is the same as 7 court of lower semiaxis
On male splined shaft segment structure parameter it is identical, directly with differential assembly to be detected coordinate.The one end of lower semiaxis 3 upward is rectangle
Tenon, the cantilever end of flattened arm 3.1 lean on the rectangle for passing through built-in rectangular and upper semiaxis 3 to 1 gauge head of dial gauge, the wrench 4
Tenon coordinates, and wrench 4 is the arm of force for directly driving differential assembly built-in gear transmission to be detected.Wrench 4 is rotated clockwise then to join
Dynamic upper semiaxis 3, constitutes differential assembly built-in gear to be detected and measures sideshake structure under location condition.Because of differential mechanism to be detected
The sideshake amount of assembly is very small, and the flattened arm 3.1 of upper semiaxis 3 is by, by 1 indicating value of dial gauge, this shows after the small sideshake measured amplification
Value just can obtain practical backlash values after simple conversion.Detection structure of the present invention is simple, simple operation, testing result really may be used
It leans on, most important is detection efficiency height.
In the present embodiment, 2 longitudinal center line of dial framework and differential assembly distance between center lines A=150mm, differential to be detected
Axle shaft gear midpoint pitch diameter B=30mm built in device assembly allows side to remove 0.1~0.2mm of error, is first pressed when reality measures upper
It is the sideshake amplification quantity measured to state step and obtain indicating value X=0.5mm, the X value of dial gauge 1, can just be obtained in X divided by fixed coefficient δ
Practical backlash values C.The present embodiment fixed coefficient δ=A ÷（B×2）=150 ÷ 60=2.5, practical 8=0.5 ÷ 2.5 of backlash values C=X ÷
=0.2mm is certified products through converting this sideshake within the scope of allowable error.From above-mentioned result of calculation it is found that the present embodiment measures
When all 1 indicating value X of dial gauge it is overproof more than the sideshake of 0.5mm, the sideshake less than 0.5mm is within the scope of permissible error, institute
All to regard as certified products.
