Background technology
In vehicle manufacture field, the outer end universal joint of drive shaft is the position being directly connected with wheel, is high speed rotating
Drive axial workpiece key component.Spline fitted is relied on to complete the biography of power between drive shaft axostylus axostyle and outer end universal joint
Passing, sometimes the overall dimensions of two kinds of internal ring is just the same, and unique difference is that the internal spline number of teeth is different, such as 34 tooth internal ring with
35 tooth internal ring, if the internal ring misloading that the number of teeth should be used few is become the internal ring that the number of teeth is many, then can cause in vehicle travel process
Power interruption, even drive shaft axostylus axostyle disengage with universal joint, lead to great security incident.
Existing universal joint assembling tool includes steel ball drawing mechanism and hand assembled frock, and steel ball drawing mechanism is by electromagnetism
Valve controls ball, and the power supply circuit of electromagnetic valve coil is controlled break-make by photoswitch.People are manual to be filled internal ring and steel ball
It is fitted in universal joint outer shroud, in order to ensure that universal joint uses correct internal ring in an assembling process, it will usually use and manually mark
The means such as knowledge, visual detection, artificial cubing detection.But these detection meanss all be unable to do without the subjective judgment of people, easily cause
Missing inspection, false retrieval, and to the requirement height of personnel, time-consuming, effort, it is impossible to always meet the prescription of product.It is thus desirable to it is a kind of
Detect accurate, time saving and energy saving novel hard error prevention device.
Summary of the invention
The purpose of the present invention solves the above-mentioned problems in the prior art exactly, it is provided that in a kind of universal joint assembling process
The error prevention device of the anti-batch mixing of internal ring, this device can 100% quick and precisely distinguish identical appearance difference number of teeth spline internal ring, keep away
In the outer end universal joint assembling process of free drive moving axis, internal ring loads in mixture the generation of phenomenon.

When having internal ring workpiece in internal ring detecting tool, photoswitch sends a signal to PLC control circuit, and PLC control circuit is sent out after processing
Giving electromagnetic valve A, electromagnetic valve A path is opened and is inflated to internal ring detecting tool；Baroceptor sensing inner gas pressure, if inflation
Air pressure can reach the threshold value of baroceptor, and baroceptor sends information to PLC control circuit, and PLC control circuit processes
After send a signal to relay, Control steel ball drawing mechanism sends steel ball, if inner gas pressure can not reach air pressure transmission
Sensor threshold value, steel ball drawing mechanism does not send steel ball.
Owing to present invention employs such scheme, when there being internal ring workpiece in internal ring detecting tool, photoswitch action, send out
The number of delivering letters gives PLC control circuit, and PLC control circuit controls electromagnetic valve A path and opens to the inflation of internal ring detecting tool；Air pressure sensing
Device sensing inner gas pressure, if the number of teeth of internal ring workpiece is identical with the external splines number of teeth of external splines spindle nose, inner gas pressure can reach
To baroceptor threshold value, baroceptor sends information to PLC control circuit, and PLC control circuit controls steel ball drawing mechanism
Send steel ball drop in operator's hands, complete to assemble；If the number of teeth of internal ring workpiece is more than the external spline teeth of external splines spindle nose
Number, then spline engagement gap is big, and inner gas pressure does not just reach baroceptor threshold value, and baroceptor does not just have information to PLC
Control circuit, steel ball drawing mechanism does not send steel ball, it is impossible to assemble, thus plays the function of mistake proofing.In a word, energy of the present invention
Enough 100% internal ring quick and precisely distinguishing identical appearance difference number of teeth spline, it is to avoid in the outer end universal joint assembling process of drive shaft
Internal ring loads in mixture the generation of phenomenon, improves the quality of Automobile drive shaft universal-joint, reduces labor intensity, improves assembling effect
Rate so that assembling steady quality is reliable, and simple in construction, easy to use, as long as changing internal ring detecting tool, just can be to multiple types
The internal ring of type detects, and it is applied widely, highly versatile.
