Description
Technical field
The present invention relates to a kind of surveying instrument, particularly detect the whether qualified instrument of internal thread specification and length.
Background technology
In machining, often run into the shaft-like workpiece that internal thread hole is arranged.At present; The check of this internal thread hole is still takes manual method of operating of tightening up a screw: promptly turn round the screw rod of using as cubing in the internal thread hole; Lean on visual and the shaft shoulder of feeling to judge screw rod whether to contact with the end face of the threaded hole of axle; If do not have the gap then for the qualified product of hole depth, if gapped then be the underproof product of hole depth.But this kind method of inspection has shortcoming: 1, method is more original, and efficient is low, can not satisfy the production in enormous quantities needs; 2, rely on people's sense organ judgement whether qualified, keep away the error or the carelessness of unavoidable judgement, be difficult to guarantee product quality.
Summary of the invention
The object of the present invention is to provide a kind of quality inspection that can guarantee to improve the internal thread grading machine of checkability again.The present invention mainly includes and handles assembly, positioning component and detection components.The manipulation assembly mainly includes: support, solenoid directional control valve, compressed air inlet pipe, compressed air outlet pipe and air motor.Wherein, On solenoid directional control valve and air motor all is fixed on base links to each other the vertical rack; Solenoid directional control valve links to each other with the compressed air inlet pipe; This solenoid directional control valve control section is with the pressurized air separated into two parts, and a part is just being changeed import through a compressed air outlet pipe and air motor and linked to each other, and another part links to each other with air motor counter-rotating import through another root compressed air outlet pipe;, can realize by air motor the operation of tightening up a screw, the operation that when air motor reverses, can realize unloading screw when just changeing.This air motor main shaft links to each other with the screw rod of using as cubing (hereinafter to be referred as a screw rod) end, and this screw rod passes positioning component and detection components successively, and the other end is a free end.Above-mentioned positioning component mainly includes: support, bearing (ball) cover, rolling bearing, sleeve and set nut.Wherein, The positioning component overall fixed with vertical rack that base links to each other on; Be provided with a rolling bearing in the bearing chamber of two relative bearing (ball) cover formations; The shaft shoulder of screw rod is stuck on the end face of rolling bearing inner ring, and screw rod passes bearing inner race, sleeve successively and is meshed with the set nut of the sleeve other end, and the screw rod stiff end links to each other with the air motor main shaft.This positioning component can be located screw rod.Detection components mainly includes: screw rod, the axis of guide, nut, catch, spring and travel switch.Wherein, the axis of guide is two Metallic rod that are located at the screw rod both sides, and preferably the axis of their axis and screw rod is in same plane.These two axis of guide one ends are separately fixed on the bearing (ball) cover, and the other end passes the through hole on spring and the catch respectively successively, by with the nut of guide pole screw-threaded engagement catch and the fastening location of spring.Catch is provided with three through holes, and the both sides through hole has the axis of guide to pass, and intermediate throughholes has screw rod to pass.On the vertical rack that travel switch is installed in base links to each other, the contact and the catch of the trip switch are relative.The trip switch also links to each other with signal (sound or light) switch, so that qualified products information is passed to the operator through vision and sound sensation.
The course of work of the present invention is following: energized and pneumatic supply turn on the power switch.At first carry out the adjustment of travel switch position; Be about to catch and move, and go out the screw rod preadmission with kind of calliper and go into minimum-depth in the product threaded hole, when finding the screw rod preadmission to go in the product threaded hole minimum-depth toward the travel switch direction; Catch is motionless; Begin to adjust travel switch and begin position immediately, be fixed on travel switch on this position then, set back catch to alerting signal.During check; Grasp the product cylinder; Aim at internal thread hole the screw rod free end and send into, the program of tightening up a screw moves to the air motor direction along screw rod along with air motor is just changeing product to be detected; When the end face of product threaded hole contacts with the catch end face, product will promote catch and move to the air motor direction together.When screw rod got into the degree of depth of internal thread hole regulation of product to be detected, catch contacted travel switch immediately, sends the signal of qualified products, again circuit is switched to simultaneously to make the counter-rotating of air motor main shaft unload the screw program, and test product is withdrawed from.Spring on the axis of guide is again with the catch pushed home simultaneously.The degree of depth of internal thread hole that gets into product to be detected when screw rod is during less than setting; Catch will touch less than travel switch, not have signal to generate, and explain that product is defective; The signal of motor spindle counter-rotating is produced; Operating personnel's manual work this moment is pressed and is forced to unload the screw button, makes the motor spindle counter-rotating unload the screw program, and underproof test product is withdrawed from.
The present invention compared with prior art has following advantage:
1, testing accuracy is high: adopt the control of travel switch Circuits System, directly reflect the quality state of product, need not manual work judge the hidden danger of having avoided human factor to bring fully.
2, checkability is high: adopting the present device used time of check only is the half the of hand test time.Can not only satisfy requirements of large-scale production, and save cost of labor.
3, operating personnel only need send into product and take off and get final product, and need not exert oneself, and have alleviated operator's fatigue strength greatly, and easy to operate.
