Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.
As shown in the figure, one perforation unit Novel mandril described in the utility model loose joint, comprise the conical surface 11 of front end, middle pedestal 8, the screw rod 10 of rear end, extend back in the middle of the front end face of the described conical surface 11 and be provided with blind hole, the axle 7 of equilateral triangle is provided with in blind hole, the width at equilateral triangle angle is 3-6mm, the side of the conical surface 11 is evenly provided with 3 guidees 4, lock pin 3 is provided with in guide 4, the wall thickness height 1-3mm of the aspect ratio conical surface 11 of described lock pin 3, pedestal 8 side is provided with T-slot 13, the mounting hole 14 of strip is provided with in T-slot 13, driving lever 5 stretches in mounting hole 14 and is connected with axle 7, the front end face of the conical surface 11 connects end cap 2 by bolt 1.
During use, top endoporus and push rod loose joint described in the utility model adopt cone to be connected, and the conical surface 11 of push rod loose joint is arranged symmetrically with the lock pin 3 that three (or more) can be movable, lock pin 3 is when locking position, lock pin 3 is stuck in the cannelure on the inner conical surface of top, and guarantee top is fixing with loose joint relative position, realizes the locking come directly towards, wherein the number of lock pin 3 is identical with the limit number of axle 7, axle 7 is triangle, and lock pin 3 is 3, and axle 7 is pentagon, lock pin 3 is 5, by that analogy.
Stirring driving lever 5 is with moving axis 7 can rotate to an angle (60 ° is best angle), the cross section that axle 7 contacts with bearing pin 3 is approximate equilateral triangle (or approximate regular polygon), there is one fixed width at equilateral triangle angle, when bearing pin 3 contacts with the angle (one section of circular arc) of the equilateral triangle (or regular polygon) on the cross section of axle 7, bearing pin 3 is outwards mobile by top, is in locking position; When bearing pin 3 contacts with the limit of the equilateral triangle (or regular polygon) on the cross section of axle 7, bearing pin 3 can move inward, and its end face lower than the loose joint conical surface, can realize the release to top locking.
For preventing causing driving lever 5 to rotate because impacting, bearing pin 3 is caused to move, lose locking effect, when driving lever 5 is in locking position, horizontal groove 15 is provided with in mounting hole 14, centre is bored foraminate locking plate 6 to be enclosed within driving lever 5 by aperture, be stuck in the groove 15 of loose joint, ensure that driving lever 5 can not rotate; In the aperture of driving lever 5, insert safety pin type split pin 9 simultaneously, prevent locking plate 6 from getting loose.
During due to top work, there are violent impact and motion, for ensureing the stable of structure, reach anti-loosing effect, what adopt between driving lever 5 and axle 7 is a kind of structure of similar Tenon, the head of wherein said lock pin 3 is semicircle, be convenient to clamping, the height of head of driving lever 5 lower than pedestal 8 cylindrical, higher than mounting hole 14 outer surface, freely can either stir, pedestal 8 surface can not be protruded again and hurt sb.'s feelings.
Perforation unit Novel mandril described in the utility model loose joint, owing to realizing top and the locking of push rod loose joint more than 2, better can ensure to come directly towards the axiality with push rod loose joint, thus better ensure the wall thickness accuracy of steel pipe; Produce burr owing to avoiding between top and loose joint, avoid the situation coming directly towards the dismounting difficulty that may occur; When top produces, need not install caudal peduncle again, a large amount of material consumption decreased, simplifies top manufacturing procedure; Can greatly reduce top manufacturing cost; Decrease the consumption as consumable accessory setting circle pin and split pin; Locking to top and release can be realized due to a driving lever only need be stirred, simplify the execute-in-place action of workman, the raising of enhancing productivity and alleviate the labour intensity of workman.
