Description

Flywheel school round punch mechanism with real-time Identification of Cracks function

Technical field

The utility model belongs to the auto parts and components detection field, refers in particular to a kind of Automobile flywheel school circular knitting machine.

Background technology

Flywheel is parts important on automobile, and the crudy of flywheel is most important concerning the security of automobile.The loop configuration that flywheel is standard, need school sired results skill in process of production, and the school round punch is as the critical component of school circular knitting machine, and its control accuracy and intellectuality are the bottlenecks of school circular knitting machine development.And in the circle process of the school of flywheel because of easily cracked by external force, because school bowlder flywheel is stressed more even, detection operation in the uncertain ，Gei Hou road of the position easily cracked is brought very large difficulty.Flywheel generally adopts the static instrumentation modes such as ultrasonic examination, x-ray inspection, and these several mode detection efficiencies are very low, and may occur undetectedly, is not suitable for the production of flywheel in enormous quantities.

Summary of the invention

The utility model provides a kind of flywheel school round punch mechanism with real-time Identification of Cracks function, and to crack in the school circle process that solves flywheel, existing static instrumentation mode detection efficiency is low, may occur undetectedly, is not suitable for the problem of producing in enormous quantities.

The technical solution of the utility model is: the piece coulisse rises, hydraulic reposition cylinder installing plate by bolt with press down substrate and be fixedly connected with, after the piece that rises is fixedly connected with by bolt and the piece locking resetting block that rises, be suspended on the T-shaped groove of the piece coulisse below of rising, and be slidably connected with the T-shaped groove of the piece coulisse that rises, the hydraulic reposition cylinder is threaded with the piece locking resetting block that rises by the external screw thread on piston rod own, the cylinder body of hydraulic reposition cylinder is fixedly connected with hydraulic reposition cylinder installing plate by bolt, the Identification of Cracks sensor that carries magnetic force is adsorbed on the piece that rises, magneto strictive sensor, the induction contact is fixedly connected with push-down head by bolt respectively.

The utility model has the advantage of: novel structure, not only on controlling, realize the control of high accuracy closed-loop, and can realize the generation of detection of dynamic crackle in flywheel school circle process, and the work of energy Based Intelligent Control school circular knitting machine, greatly improved operating efficiency, precision is high, avoids occurring undetected, and can cancel manual static and detect operation.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

In figure, push-down head 1, press down substrate 2, the piece coulisse 3 that rises, hydraulic reposition cylinder installing plate 4, hydraulic reposition cylinder 5, the piece that rises locking resetting block 6, the piece 7 that rises, magneto strictive sensor 8, Identification of Cracks sensor 10, induction contact 9, Fibre Optical Sensor 11, detected workpiece 12.

The specific embodiment

Piece coulisse 3 rises, hydraulic reposition cylinder installing plate 4 by bolt with press down substrate 2 and be fixedly connected with, the piece 7 that rises is fixedly connected with on the T-shaped groove of rear-mounted below the piece coulisse 3 that rises with the piece locking resetting block 6 that rises by bolt, and be slidably connected with the T-shaped groove of the piece coulisse 3 that rises, hydraulic reposition cylinder 5 is threaded with the piece locking resetting block 6 that rises by the external screw thread on piston rod own, the cylinder body of hydraulic reposition cylinder 5 is fixedly connected with hydraulic reposition cylinder installing plate 4 by bolt, the Identification of Cracks sensor 10 that carries magnetic force is adsorbed on the piece 7 that rises, magneto strictive sensor 8, induction contact 9 is fixedly connected with push-down head 1 by bolt respectively.

Push-down head, press down substrate, Fibre Optical Sensor 11 all is fixed on bearing frame, at the school bowlder, by the part push-down head, moved downward, by the conical surface, downforce is passed to the part piece that rises, the outside moving handle of the piece that rises cover detected workpiece 12 thereon holds round, and push-down head rises, and by the hydraulic reposition cylinder piece that promotes to rise, gets back to home position, unload again detected workpiece 12, in the circle process of school, the crackle voice signal that detects workpiece 12 passes to the Identification of Cracks sensor by the piece that rises, and completes the crack detection process.

During undershoot school circular knitting machine structure original state, all mechanisms are mentioned by push-down head, in vacant state, rise by piece under the effect of hydraulic reposition cylinder, are retracted to minimum state, and by the magneto strictive sensor control position, whole mechanism is in zero-bit.

Workflow:

Push-down head is with the downward high-speed motion of whole mechanism, when the piece that rises is pressed onto detected workpiece surface, due to detected workpiece support, except push-down head, other mechanism stops moving downward, push-down head continues at a high speed downwards, until the Fibre Optical Sensor signal triggers, push-down head presses down at a slow speed, now start the crack detection function, the push-down head lower inclined plane with rise in piece after inclined-plane contacts, continue downwards, the piece that will rise pushes to surrounding, overcome the frictional force on resistance and the inclined-plane of hydraulic reposition cylinder, rise by piece to the surrounding spreading, the continuous spreading of the piece that rises, after following external cylindrical surface contact workpiece inner cylinder face, rise piece together with detected workpiece to the surrounding spreading, until pressing down, magneto strictive sensor report push-down head puts in place, push-down head promotes at a slow speed, detected workpiece is along with the piece that rises inwardly shrinks, until inner cylinder face breaks away from the piece that rises, the piece that rises continues to shrink under the effect of hydraulic reposition cylinder, until after being retracted to minimum state, rise piece and push-down head breaks away from, push-down head continues to promote at a slow speed, until the Fibre Optical Sensor signal triggers, push-down head promotes at a high speed, now close the crack detection function, after push-down head promotes a bit of distance, driving whole mechanism promotes together, whole mechanism breaks away from detected workpiece surface, continue to rise, until magneto strictive sensor is posted a letter, mechanism arrives the top zero-bit.
