Description
Technical field
The utility model relates to a kind of flank of tooth jitter detection apparatus, specifically a kind of gear radial clearance and flank of tooth bounce inspection
Survey device.
Background technique
The detection method beated in assembly shop about gear radial clearance and the flank of tooth at present mostly uses artificial progress, manually
Detection is even more time-consuming and laborious for large-sized work piece hoisting not there is only complex for operation step, and error range is big, detection
Precision is not high, and when detecting large batch of assembly bearing, worker easily generates fatigue.Therefore, it is necessary to design between a kind of gear radial direction
Gap and flank of tooth jitter detection apparatus and detection method.
Summary of the invention
The purpose of this utility model is that in view of the deficiencies of the prior art, it is simple and convenient to provide a kind of structure, may replace people
The gear radial clearance and gear teeth face jitter detection apparatus that work is detected automatically, the device detection accuracy is high, and efficiency is fast.
To achieve the above object, the technical solution of the utility model is: a kind of gear radial clearance and flank of tooth glitch detection
Device is installed on robot arm, the device include hard cylinder, laser range finder, shell, sensors in place, round bar,
Spring, the hard cylindrical upper portion is processed into measurement plane, intermediate to connect shell by round bar, and round bar front end and hard cylinder are solid
Fixed connection, shell is inserted into round bar rear end, and can move freely；Be socketed with spring on round bar, both ends of the spring respectively with hard cylinder
It is connected with shell；Laser range finder, the survey of the ranging range face hard cylinder of laser range finder are installed on the shell
Plane is measured, the rear portion of shell is installed in place sensor.
Further, the front end of the round bar passes through screw thread and hard cylinder immovable fitting.
The utility model compared with prior art, the beneficial effect is that: detection efficiency is fast, flexible and convenient, precision is high, can fit
Answer the radial clearance of the gear of various different size models and the detection of flank of tooth bounce.
Detailed description of the invention
Fig. 1 is the gear radial clearance and gear teeth face jitter detection apparatus main view of the utility model；
Fig. 2 is the gear radial clearance of the utility model and the schematic diagram of gear teeth face jitter detection apparatus detection work.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, 2, a kind of gear radial clearance and flank of tooth jitter detection apparatus, including hard cylinder 1, laser ranging
Instrument 2, shell 3, sensors in place 4, round bar 5 and spring 6.Gear radial clearance and flank of tooth jitter detection apparatus are installed on robot
On mechanical arm, measurement plane is processed on 1 top of hard cylinder, and centre is threaded hole, and laser range finder 2 is mounted on shell 3
On, in the measurement plane of ranging range face hard cylinder 1, sensors in place 4 is mounted on the rear portion of shell 3.Before round bar 5
End is by screw thread and 1 immovable fitting of hard cylinder, and shell 3 is inserted into 5 rear end of round bar, and can move freely, and spring 6 is mounted on round bar
On 5,6 one end of spring and hard cylinder 1 are connected, and the other end and shell 3 connect.
The course of work of the utility model:
Measure radial clearance: under the premise of interior outer gear ring has assembled, the first step, internal gear need to be lifted by external force along axial
It rises to vacant state, hard cylinder 1 moves radially in tooth socket under the action of mechanical arm at this time, when hard cylinder 1 is unlimited
When close to flank profil, spring 6 plays buffer function, and round bar 5 starts to retract, and mechanical arm stops after the induction in place of sensor 4 of rear end
Advance, distance (be denoted as D1) of the laser range finder 2 by the selected datum mark of measurement at the measurement plane of hard cylinder 1, second
Step, after external force makes internal gear move radially extreme position (outer ring is motionless, and inner ring moves radially), hard cylinder 1 is in machinery
It is moved radially in tooth socket under the action of arm, when hard cylinder 1 is close to flank profil, spring 6 plays buffer function, and round bar 5 is opened
Begin to retract, mechanical arm halts after the induction in place of sensor 4 of rear end, and laser range finder 2 arrives the selected datum mark of measurement
Distance at the measurement plane of hard cylinder 1, the difference which is denoted as D2, D2 and D1 is radial clearance, to be more accurate,
It is averaged after rotatable internal tooth by above-mentioned two steps same method multimetering.
Measure flank of tooth bounce: under the premise of interior outer gear ring has assembled, external force mechanisms rotate internal gear, hard cylinder
1 moves radially in tooth socket under the action of mechanical arm, and when 1 infinite approach flank profil of hard cylinder, spring 6 plays buffering and makees
With round bar 5 retracts, and mechanical arm halts after the induction in place of sensor 4 of rear end, and laser range finder 2 arrives datum mark
Distance (being denoted as d1) at the measurement plane of hard cylinder 1, mechanical arm retract, external force drive inner ring rotation, robotic arm recycle into
Row ranging movement, carries out ranging (be denoted as d2, d3 ... dn) every a certain number of teeth, after multiple point measurements, all distance measurement values
Do difference calculating automatically in computer system, obtained maximum value and minimum value is flank of tooth jitter values.
