Abstract
Live center testing agency in automatic Gear separator, it is a kind of new gear testing mechanism, suitable for high-volume, the gear testing of fast beat.Traditional automatic Gear separator, clamping gear use back dead centre structure mostly, and gear produces hard friction always with top during detection, abrasion just occurs using a period of time back centre, it is necessary to periodically be changed, more important is the accuracy of detection for influenceing instrument.The live center testing agency of this patent, the structure for having used bearing, steel ball to keep set and cylinder to be combined, when making detection gear, it is top as gear synchronous operates, it is top that hard friction is no longer produced between gear, top extent of deterioration is greatly reduced, preferably ensure that the accuracy of detection of instrument, improves the reliability and stability of instrument.
Description
Technical field
Live center testing agency in automatic Gear separator, it is a kind of new gear testing mechanism, suitable for big
In batches, the gear testing of fast beat.
Background technology
Automatic Gear separator, because its automaticity is higher, detection product beat quickly, it is necessary to it is continual enter
Row Product checking, the loss to instrument detection part is larger, it is therefore desirable to the detection main part of instrument have it is very high reliable
Property and stability.Conventional automatic Gear separator, clamping workpiece gear use back dead centre structure mostly, in detection, top
Point be not with gear operation, this result in it is top produce hard friction always between gear center hole, even if using rigidity
Stronger material（Such as hard alloy）Make it is top, using after a period of time still just occur abrasion, it is necessary to periodically carry out more
Change, and its cost is higher, process-cycle length, difficulty of processing is big, and more important is the accuracy of detection for influenceing instrument.
The content of the invention
Using the live center testing agency of this patent, substitute traditional back dead centre testing agency, eliminate during detection it is top with
Caused hard friction between centre bore, reduces top extent of deterioration, preferably ensures the accuracy of detection of instrument, improves instrument
Reliability and stability.
Due to the live center testing agency that automatic Gear separator uses, bearing, steel ball has been used to keep set and cylinder
The structure being combined, it is top as gear synchronous operates when making detection gear, it is top that hard friction is no longer produced between gear,
Replaced by the rolling friction of steel ball, greatly reduce the top degree of wear, top use bearing steel material, which is manufactured and done, to be quenched
Fire processing, its strong, handling ease of rigidity, easy to assembly, cost is suitable, preferably ensure that the accuracy of detection of instrument, carries significantly
The high reliability and stability of instrument.
Brief description of the drawings
Fig. 1 is instrument clamping gear general illustration；
Fig. 2 is live center testing agency profile.
Embodiment
Installation way of the instrument when detecting gear as shown in figure 1, it is characterized in that：A left side top 3 and the right side top 5 are fixed respectively
In left dead head 2 and right dead head 6, cylinder 1 and cylinder 7 are connected with a left side top 3 and the right side top 5 respectively, and its clamping process is：
Cylinder 1 and cylinder 7 act on, and promote a left side top 3 and the right side top 5 respectively, it is moved respectively in left dead head 2 and right dead head 6
It is dynamic, in the left and right top left and right center hole for withstanding on workpiece gear 4 respectively and compress, complete the clamping of workpiece gear 4.
During detection, a left side top 3 and right top 5 all run-in synchronisms with the operating of workpiece gear 4.
Live center testing agency is as shown in Fig. 2 its composition includes：Cylinder 1, left dead head 2, left top 3, cylinder contiguous block
8th, top block 9, cover plate 10, center sleeve 11, the steel ball of connecing keeps set 12, thrust ball bearing 13, connected nail 14, push-and-pull block 15, cylinder
Fixed seat 16, it is characterized in that：Steel ball keeps set 12 to be enclosed on a left side top 3, and steel ball keeps set 12 to be enclosed in center sleeve 11, and ensures
It is fixed between three for interference fit, center sleeve 11 on left dead head 2, cover plate 10 is fixed on center sleeve 11, thrust ball axle
The blowout patche and connected nail 14 for holding 13 are interference fit, ensure that the seat ring of thrust ball bearing 13 is freely lived on the axle of connected nail 14
It is dynamic, and steel ball is not fallen off, the top block 9 that connects is fixed on a left side top 3 by connected nail 14, and cylinder contiguous block 8 is fixed on top connect
On block 9, push-and-pull block 15 is fixed on the gas bar of cylinder 1, ensures that push-and-pull block 15 can be in cylinder contiguous block 8 and thrust ball bearing 13
Seat ring between freely activity, cylinder 1 is fixed in cylinder fixed seat 16.
During detection, cylinder 1 acts on, and push-and-pull block 15 is against the seat ring upper surface of thrust ball bearing 13, promote sleeve mechanism to
Preceding motion, make the left center hole of left top 3 workpiece pressing gear 4（The right side top 5 is right top equally to act workpiece pressing gear 4
Hole）, in the tested operating of workpiece gear 4, force of rolling friction is very small as caused by steel ball, and a left side top 3 can be with the fortune of gear
Then run-in synchronism, after detection, cylinder 1 acts on, and push-and-pull block 15 pulls cylinder contiguous block 8, drives sleeve mechanism to transport backward
It is dynamic, recall a left side top 3（The right side top 5 is withdrawn with same action）, take workpiece gear 4 away, you can continue next workpiece tooth
The automatic detection of wheel.
