The detecting device comprises a piercing plug (1), a connecting body (2), a pushing pole (5), a piercing plug groove (6) arranged in the inner hole of the piercing plug (1), a pin bush (3) arranged in a pin hole on a raised head of the connecting body (2) and a pin (4) which is movably arranged in the pin bush (3); a section of conical cylinder is arranged between a big head (11) and a small head (12) of the pushing pole (5), the conical inclination angle alpha (9) of the conical cylinder is 7.4 degrees to 18.4 degrees, a section of the conical cylinder is movably arranged at the position of the pin hole on the raised head of the connecting body (2) and is movably matched with the pin (4), a displacement sensor (7) is arranged on the pushing pole (5) and is electrically connected with CPU together. The detecting device improves the reliability of the piercing plug quick change device.
Description
Technical field
The present invention relates to the tapping machine equipment in the metallurgy industry seamless steel tube production field, particularly the pick-up unit that whether puts in place of the quick replacing in the top of tapping machine.
Background technology
The top quick replacement device that is used for tapping machine is satisfying under the prerequisite of technological requirement, should come directly towards to change rapidly, guarantees safe and reliable again.Existing top quick replacement device can satisfy the quick-replaceable requirement in top, but reliability is lower.In the replacing process of top; occur in the top through regular meeting and change under the situation not in place, the tapping machine perforation that works on causes tapping machine not have and comes directly towards rolling accident; cause huge waste, so the pick-up unit that whether puts in place is changed in the on-the-spot detection top of being badly in need of a kind of simple economy of exploitation.
Summary of the invention
The invention discloses a kind of device for detecting rapid replacement and positioning of punch head, the detection that provides the quick replacing in top of tapping machine whether to put in place, solved in the top and changed under the situation not in place, the tapping machine perforation that works on, cause tapping machine not have the rolling accident in top, cause the technical matters of huge waste
The present invention overcomes the above problems by following scheme:
Device for detecting rapid replacement and positioning of punch head, comprise top 1, connector 2, push rod 5, the top groove 6 that is provided with in the endoporus of top 1, the pin 4 of guide 3 that is provided with in the pin-and-hole on the plush copper of connector 2 and movable setting in guide 3, between the push rod major part 11 of described push rod 5 and push rod microcephaly 12, be provided with one section tapered cylinder, the tapering pitch angle a9 of this tapered cylinder is 7.4 °-18.4 °, this section tapered cylinder is movably arranged on the pin-and-hole place on the plush copper in the connector 2, and with described 4 movable cooperations of pin, push rod 5 is provided with displacement transducer 7, displacement transducer 7 is electrically connected with CPU8, and the left and right displacement of push rod 5 can be measured in real time by CPU8.
The tapering pitch angle a9 of described tapered cylinder is preferably 12.5 °.
The bottom surface of described pin 4 can be the inclined-plane, closely cooperates with one section tapered cylinder activity on the push rod 5.
The present invention has improved the reliability of top quick replacement device, prevents from not have the generation of the rolling accident in top.Simultaneously, improved the operating rate of top quick replacement device, reduced the top and consumed.

Embodiment
Device for detecting rapid replacement and positioning of punch head, comprise top 1, connector 2, push rod 5, the top groove 6 that is provided with in the endoporus of top 1, the pin 4 of guide 3 that is provided with in the pin-and-hole on the plush copper of connector 2 and movable setting in guide 3, between the push rod major part 11 of described push rod 5 and push rod microcephaly 12, be provided with one section tapered cylinder, the tapering pitch angle a9 of this tapered cylinder is 7.4 °-18.4 °, this section tapered cylinder is movably arranged on the pin-and-hole place on the plush copper in the connector 2, and with described 4 movable cooperations of pin, push rod 5 is provided with displacement transducer 7, displacement transducer 7 is electrically connected with CPU8, and the left and right displacement of push rod 5 can be measured in real time by CPU8.
The tapering pitch angle a9 of described tapered cylinder is preferably 12.5 °.
The bottom surface of described pin 4 can be the inclined-plane, closely cooperates with one section tapered cylinder activity on the push rod 5.
The top quick replacement device mainly is made up of connector, cover, pin, push rod etc., when changing the top, push rod pushes away forward, pin in the pin-and-hole in connector is withdrawn in the hole, the head of the pin in the top groove that extend in the endoporus of top is returned in the pin-and-hole of connector, after unloading old top and changing new top, push rod pushes away to the right, pin is moved to major part from the microcephaly along the outside surface of the tapered cylinder of push rod, make the head of pin reach connector and enter in the top groove in the endoporus of top the stuck new top of changing outward.Come directly towards improper locking by two kinds may: one, drop on the pin overhang the when overhang of pin is normally locked less than the top between top afterbody and the top groove back edge.Two, the top afterbody drops on pin front portion even top disengaging connector, the overhang the when overhang of pin is locked greater than the top is normal.So relatively Xiao overhang e can learn whether the top locks.Again because there is the trigonometric function relation between the overhang of the overhang of pin and push rod, be tg α=c/d, c=(a-b)/2, the overhang e that is to say pin funtcional relationship that is directly proportional with the left and right horizontal displacement of push rod, and the left and right displacement amount of push rod has displacement transducer to detect, whether CPU just can judge the top by the overhang e that judges pin with setting value and lock, thereby raising comes directly towards the reliability of quick replacement device.Consider that in actual production all there are wearing and tearing in pin and connector, coefficient is revised in addition in electric-control system.
