Description

The screw thread detector

Technical field:

The utility model relates to a kind of instrument that is used to detect threaded fastener, specifically is a kind of automanual screw thread detector.

Background technology:

The screw thread testing goal of threaded fastener is whether the footpath on of the tested screw thread of check surpasses the middle footpath of its maximum solid tooth form and detect footpath, end physical size whether surpass its maximum material size, thereby identifies whether the screw thread on the threaded fastener is qualified.At present, the screw thread of double thread securing member detects and generally still adopts manual mode, promptly screw by thread profile gauge such as plug thread gauge or ring thread gage and tested screw thread, if tested screw thread can with the thread profile gauge tight engagement, represent that then tested screw thread is qualified screw thread, if tested screw thread can not be well and the thread profile gauge tight engagement, represent that then tested screw thread is defective screw thread.But, the mode of this manual inspection screw thread not only exists labour intensity big, the problem that detection efficiency is low, but also because of detecting, long repeatability makes the tired operation of testing staff easily, thereby cause the reduction of accuracy of detection, cause some screw thread bastard thread fastener products to be sneaked in the qualified threaded fastener product.

The utility model content:

The technical problems to be solved in the utility model is that the screw thread that a kind of labour intensity is little, detection efficiency is high and accuracy of detection is high detector is provided.

Technical solution of the present utility model is, a kind of screw thread detector with following structure is provided, and it comprises standard screw thread gauge detection head, motor, advancement sensor, reverse sensor, torque sensor, moment of torsion connector, anchor clamps, with advancement sensor with reverse touch panel, the gauge tap that sensor is used and can be installed in the base on the worktable and be provided with the Electric Appliance Cabinet of control system; Described motor mounting is on right instrument stand; Described moment of torsion connector is connected with the output shaft of motor; Described anchor clamps are connected on the output shaft of moment of torsion connector; Described standard screw thread gauge detection head is removably mounted on the anchor clamps; Described advancement sensor and reverse sensor are installed on the base and distance are arranged between the two; Described torque sensor is installed on the left instrument stand and with the moment of torsion connector and contacts; Described touch panel and base are slidingly matched; Be connected with spring between described touch panel bottom and the base; Described touch panel top is provided with a bayonet socket that can block tested threaded fastener; Described advancement sensor, reverse sensor, torque sensor and gauge tap all are connected with control system.

After adopting above structure, compared with prior art, the utlity model has following advantage: when the threaded fastener that detects the workman and will need to detect screw thread is placed on the bayonet socket at touch panel top, touch panel can be given signal of advancement sensor, and advancement sensor can be delivered to this signal in the control system, thereby make motor begin just to change, when motor rotates, the threaded fastener of detected screw thread will screw on the standard screw thread gauge detection head, can drive touch panel when threaded fastener screws moves right, compression was connected the spring between touch panel bottom and the base when touch panel moved right, if the threaded fastener of detected screw thread can fully closely screw on the standard screw thread gauge detection head, represent that then detected screw thread is qualified, and when threaded fastener fully closely screws on the standard screw thread gauge detection head, touch panel can contact with the reverse sensor, reverse signal of sensor thereby give, reverse sensor this signal is passed to motor, thereby impel motor to begin to reverse, thereby the threaded fastener of qualified tested screw thread is screwed out from the standard screw thread gauge detection head, meanwhile, under the restoring force effect of spring, touch panel also returns to initial position; When if the threaded fastener of detected screw thread can not fully closely screw on the standard screw thread gauge detection head, although touch panel has carried out certain compression to spring, but touch panel can not contact with the reverse sensor, this moment, the moment of torsion connector can be thrown off voluntarily, the threaded fastener of detected screw thread stops the rotation, and motor continues just changeing, when sensing Stop message, torque sensor Stop message can be sent to control system, control system will be given reverse signal of motor, thereby the moment of torsion connector is overlapped, detect the workman this moment and just the threaded fastener difference of this screw thread bastard thread securing member and standard can be come.The utility model has been realized the semi-automation control that screw thread detects by above-mentioned principle of work just, thereby makes the utility model not only reduce the detection working strength of workers, has improved the work efficiency that detects, and has improved the precision that screw thread detects greatly.

A case is stamped in a kind of improvement of the present utility model of writing a composition on described left instrument stand and the right instrument stand.Being provided with of case can prevent effectively that dust and other impurities from influencing the operate as normal of moment of torsion connector.

As another kind of the present utility model, the output pedestal of described moment of torsion connector cooperates on left instrument stand and with left instrument stand is rotatable.Of the present utility model this improves and improves the stability that anchor clamps rotate, thereby further improves the precision that the utility model detects.
