Description
Technical field
The present invention relates to Cam Detection technical field, more specifically to the on-line checking of a kind of cylindrical cam outline
Mechanism.
Background technology
In the assembling of nose-gear, repair two cylindrical cam is an important process to effectively engagement.Tradition
Repairing method be manually undercarriage is strained after, i.e. ensure that the outline of two cylinders is adjacent to completely, measure undercarriage hind axle
The difference in height at two ends.If two cam-engaged are complete, then difference in height ideal situation is zero, reaches difference in height by repair cam and is
Zero or in allowed band.If repair of cam is defective, also to repeat heavy thick dress detection process, whole detection is convex
Take turns the most qualified during, operator need manually undercarriage to be carried out push-and-pull, check, dismounting, operation is loaded down with trivial details, workload
The biggest；The inaccuracy that hand dipping causes directly affects precision.
State Intellectual Property Office, on 03 17th, 2010, discloses Publication No. CN101673485, entitled
The patent of invention of " measure of cam contour and simulating cutting assay device ", this patent of invention belongs to the experimental provision of mechanical field,
Specifically a kind of measure of cam contour and simulation processing experimental device, the motion profile of cam can be detected, simultaneously by it
Can also simulating cutting cam.Measure of cam contour and simulation processing experimental device, including rack, survey profiling mechanism, tested convex
Wheel installing mechanism and simulating cutting experiment mechanism, survey profiling mechanism include linear displacement transducer, cylindrical cam survey wide bar with
And disc cam surveys wide bar, tested cam installing mechanism include being installed on rack and be connected with rotational power for installing
The camshaft of tested cam；Simulating cutting mechanism includes mill section and the worktable part of vertical milling form, described work
Platform parts include that can produce three axles moves the drive mechanism rotated with an axle and the workbench installed on it.The present invention's is useful
Effect: collection cam profile board design is processed and is detected as one, multiple functional, compact conformation is real on an experiment porch
Show a tractor serves several purposes.
But this patent of invention does not relate to the operation sequence during undercarriage assembling, it is impossible to measure cam
Stressing conditions after engagement, and the height at rear rotating shaft two ends, it is still necessary to the operation overturn by operator is realized, therefore,
In the assembling of prior art nose-gear, repair two cylindrical cam to effectively engagement is manually by after undercarriage tension, i.e. ensures
The outline of two cylinders is adjacent to completely, measures the difference in height at undercarriage hind axle two ends, if repair of cam is defective, also
Repeating heavy thick dress detection process, during whole detection cam is the most qualified, operator need artificial to rising and falling
Frame carries out push-and-pull, checks, dismounting, operation is loaded down with trivial details, workload is the biggest；The inaccuracy that hand dipping causes directly affects precision.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides the on-line checking machine of a kind of cylindrical cam outline
Structure, present invention is mainly used for effectively alleviating the operation sequence that during nose-gear assembles, operator are heavy.This mechanism is permissible
On-line measurement goes out the stressing conditions after cam-engaged, and the height at rear rotating shaft two ends, proposes for cam repair direction and size
Guiding opinion, it is ensured that assembly precision, provides a developing direction for undercarriage assembly automation assembling.
In order to solve problem and the defect that above-mentioned prior art exists, the present invention is achieved through the following technical solutions:
A kind of on-line monitoring mechanism of cylindrical cam outline, it is characterised in that: include undercarriage urceolus, undercarriage piston

Support member the same side, described top board is arranged between upper limit part and lower limit part, and described top board is with Linear displacement transducer even
Connect.
Being provided with groove on described support member, described groove coordinates with rear rotating shaft, rotating shaft after fixing.
Described support member lower end is provided with elastic component, and the effect lower support element at elastic component fits together with rear rotating shaft.
Being connected with elastic component on described top board, the effect lower roof plate at elastic component fits together with rear rotating shaft.
Described support member both sides are provided with top board, Linear displacement transducer, upper limit part and lower limit part.
Compared with prior art, the useful technique effect that the present invention is brought shows:
1, in the present invention, cam can on flexible frock about on-line checking height, obtain cam repair suggestion.
Dynamometry angle measurement props up bearing for rotating shaft after drawing, and the two ends of rear rotating shaft ride over dynamometry and angle measurement is propped up in the fixed support surfaces of bearing.
When pulling force increases, and after rear rotating shaft produces drift angle due to cam-engaged, dynamometry angle measurement is propped up the top board at bearing two ends and begun by spring
It is attached to below rear rotating shaft eventually, rear rotating shaft two ends height or difference in height can be recorded online, thus obtain drift angle value.Then pass through
Empirical data, offers guidance and suggestion for cam correction.
2, rotating shaft after supporting member supports, left and right top board is used for surveying height or difference in height, and Linear displacement transducer is measurement portion
Part, simultaneously its Self-resetting elastic component top board jack-up is made its all the time with rear rotating shaft below tangent.
3, in the case of preferable cam-engaged, rear rotating shaft props up the laying state in bearing in dynamometry angle measurement.Turn the most afterwards
Axle horizontal is propped up in dynamometry angle measurement on the supporting surface in bearing, and the right angle top board at its two ends is equal with it simultaneously.This is perfect condition,
In actual application, as long as both sides difference in height can use in allowed band.
4, rear rotating shaft dynamometry angle measurement prop up the upper left end of bearing reach limit superior time.This dynamometry angle measurement props up what bearing can be measured
Maximum height difference.If difference in height continues to increase, then can only be calculated by monolateral drift angle；Now can also be by increasing line
The effective travel of property displacement transducer, then relaxes bound site to expand its measurement capability.
