The utility model discloses an internal thread depth automatic detector. The technical problem needed to solve is to provide the internal thread depth automatic detector which is high in detection accuracy and applicable to batch detection. In order to solve the aforementioned technical problem, the following technical scheme is adopted by the utility model. The internal thread depth automatic detector comprises a control system which is respectively connected with a tooth gauge rotating mechanism and a displacement drive and monitoring system. The tooth gauge rotating mechanism comprises a push cylinder, a micro motor, a flexible shaft and a tooth gauge. The displacement drive and monitoring system comprises a miniature pneumatic sliding rail and a displacement sensor. Compared with detectors in the prior art, batch detection efficiency of internal threads is substantially enhanced. Besides, the internal thread depth automatic detector is high in detection accuracy so that misjudgment rate is greatly reduced, and a problem that automatic detection of internal threads of a miniature metal piece or a fastening piece is performed by utilizing the tooth gauge is solved.
Description
Technical field
The utility model relates to a kind of depth of internal thread automatic detecting machine.
Background technology

Micromotor described in the utility model and displacement transducer are set up in parallel.
The utility model compared with prior art, the mass detection efficiency of internal thread is significantly promoted, and accuracy of detection is high, and the probability of erroneous judgement also reduces greatly, has solved small-sized metal piece or securing member internal thread hole and has utilized the full-automatic difficult problem detecting of tooth rule.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1 and Figure 2, the utility model depth of internal thread automatic detecting machine, comprises control system, and control system is comprised of controller and interlock circuit.This control system connects respectively tooth rule rotating mechanism and displacement drive and monitoring system, tooth rule rotating mechanism comprises propulsion cylinder 1, micromotor 2, flexible axle and tooth rule, displacement drive and monitoring system comprise minitype pneumatic slide rail 4 and displacement transducer 3, and micromotor 2 and displacement transducer 3 are set up in parallel.Wherein, propulsion cylinder 1 connects micromotor 2 by motor mounting base 3, and the front end of micromotor 2 connects tooth by flexible axle advises, and flexible axle is polyurethane (PU) flexible axle.Micromotor 2 is also connected with current sensor, and this current sensor is Hall current sensor.
The concrete steps that the utility model carries out tooth line depth detection are as follows:
1. manually workpiece is filled in tool bar; → 2. workpiece puts in place, start button; → 3. workpiece (putting in place) in pneumatic cylinder clamping fixture bar; → 4. propulsion cylinder is released (displacement transducer detects and puts in place); → 5. micromotor forward (displacement transducer detects and twists into); → 6. propulsion cylinder keeps dying, micromotor forward; → locked rotor current 7. detected, micromotor reversion (displacement transducer detects and twists into the degree of depth); → 8. tooth rule are exited, and propulsion cylinder is return (displacement transducer inspection is return and put in place); → 9. servo next workpiece position of tool bar that moves to; → 10. single detects and finishes, and duplicate detection is that the 5th step to the nine steps loop.Wherein, pneumatic cylinder is for clamping work pieces tool bar, and propulsion cylinder promotes tooth line detection motor and drives displacement transducer simultaneously; Micromotor is just transferring screw thread to and is twisting into direction, and micromotor is reversed to the screw thread direction of back-outing; The rotating of micromotor is controlled and is controlled by Hall current sensor stall, and tooth line depth detection is controlled by displacement transducer.
The utility model micromotor front end is installed the polyurethane flexible axle that adopts PU material to make, and tooth rule are installed on flexible axle.The working current of current sensor Real-Time Monitoring micromotor, and feed back to control system, realize micromotor moment of torsion and control, indirectly limit the torsion of tooth rule.On the worktable of servo driving, design air-actuated jaw, can fix fast workpiece to be checked.Movable workbench can make the inner bolt hole of workpiece to be checked on worktable once enter detection zone, reaches the object of batch detection.For some, can adopt the workpiece of feed mechanism feeding, also can adopt automatic feed mechanism, workpiece is sent into detection zone, realize automatically and detecting.
