Abstract

The utility model relates to a distortion puller with two claws, which comprises a mandril, a left claw and a right raw. The utility model is characterized in that the top of the mandril has a central drilling hole, a force application pole of a square nose punch in a cavity is arranged parallel to the drilling hole and spirally connected by a screw, the other end is fastened by a bolt and a gasket; a supporting pole is arranged under the mandril; the cavity of an end of the supporting pole is provided with a special avalanche knife; the cavity of the other end is at least provided with a butt-joint dowel of a drawing-closer, an end of the supporting pole is sealed by a thread screw, a left arm and a right arm of the supporting pole are provided with puller claw that is provided with a pilot hole; the bottom of the force application pole has an oil hole spirally connected the top. The device has advantages of compact structure, reasonable arrangement, large application and easy carryover.

Description

Be out of shape two pawls and draw horse

The utility model relates to a kind of distortion two pawls and draws horse, and particularly a kind of distortion applied widely two pawls draw horse.

Existing various hydraulic pressure draw horse and two pawls to draw horse on the market, and they are made up of push rod and pulling claw, and its main task is that folding is got wheel, bearing, lining etc.Its shortcoming is, the scope of application is little, and utilization ratio is low.

Task of the present utility model is that proposition is a kind of applied widely, practical, and distortion two pawls of one-object-many-purposes, many combinations draw horse.

Task of the present utility model is finished like this, it comprises draws the horse push rod, left and right sides pusher dog, it is characterized in that: spiral push rod upper end has a center to change the hole, be parallel to place, commentaries on classics hole boosting-rod is housed, in the cavity of boosting-rod one end the tack punching pin is housed, screw on by screw plug, the other end combines fixing with packing ring with the anticreep screw, on the push rod below the boosting-rod support bar is housed, in the cavity of support bar one end special use is housed and separates cutter, butt joint stud at least one pin removal is housed in the other end cavity, one port of support bar seals with screw plug, is hung with on the support bar left and right arms and draws the horse pusher dog, is equipped with the different pilot hole of symmetrical purposes on the pusher dog, end at the spiral push rod has an oil filler point, is connected with lubricated top on the oil filler point.

The utlity model has following effect: draw at existing two pawls on the structure of horse and improve, make full use of the inside and outside variation of master unit and the combination of accessory, can pull out outward, again can in draw, be pin removal, be again baby press, can proofread and correct straight-bar, again can bend pipe distortion, can be shaped by bent plate, again can pressing bearing work with lining etc.Advantages such as this instrument has embodied practical significantly, particularly more can demonstrate one-object-many-purposes in the open air, has multiple combination, and compact conformation is easy to carry, rationally distributed, and is easy to spread and implement.

Drawing explanation: 1. screw 2. packing rings 3. spiral push rods 4. centers are changeed hole 5. boosting-rods, 6. pusher dogs cover hold-down screw 7. and are separated cutter 8. support bars 9. pusher dogs and overlap pusher dog 16. stiffeners 17. support bar plugs 18. tops (a, b, c, d) 19. lengthening outer plucking claw 20. double-screw bolts (a, b, c), 21. fixed heads in 15. lengthenings of 10. pusher dogs, 11. pusher dog hold-down screws, 12. nuts, 13. pusher dog packing rings, 14. push rods top

Describe embodiment in detail in conjunction with above accompanying drawing, the utility model is out of shape two pawls and draws the horse owner to be made up of spiral push rod 3, boosting-rod 5, support bar 8 and pusher dog 10.Spiral push rod 3 upper ends have a center to change hole 4, and boosting-rod 5 is equipped with in the commentaries on classics hole in the center, in the cavity of boosting-rod 5 one ends the tack punching pin is housed, and are screwed on by screw plug, and the other end is fixing with anticreep screw 1 and packing ring 2.On the push rod 3 below boosting-rod 5 support bar 8 is housed, be equipped with in the cavity of one end of support bar 8 and separate cutter, double-screw bolt 20 (a of three different structures of pin removal butt joint are housed in the other end cavity, b, c) (see Fig. 2, Fig. 3, Fig. 4), one port of support bar 8 seals with screw plug, be hung with pusher dog 10 on support bar 8 left and right arms, be equipped with the different pilot hole of purposes of symmetry on the pusher dog 10, outer plucking claw 15 in the lengthening, 19 are contained in the pilot hole with hold-down screw 11, nut 12, packing ring 13 is fixing, end at spiral push rod 3 has an oil filler point, spin lubricated with push rod top 14, there is following different structure top 18, as Fig. 5, Fig. 6, Fig. 7, Fig. 8.Group is when becoming pin removal, as long as the screw 1 and the packing ring 2 of an end of boosting-rod 5 taken off, loads onto the double-screw bolt of pulling pin (seeing Fig. 2, Fig. 3, Fig. 4), again Figure 10 drawn horse positioning and fixing plate 21 to be fixed on the pusher dog 10 to get final product.When group becomes small-sized hand-operated forcing press, unload and separate cutter 7, it is fixing to draw horse positioning and fixing plate 21 to be fixed in the pilot hole of pusher dog 10 with screw 11 and nut 12, pusher dog packing ring 13 after the standing screw that again pusher dog put 6 is loosening, again separate cutter 7 be loaded on original position small-sized hand-operated forcing press.Pull out and draw as finishing, as long as on pusher dog 10, install the inside and outside pusher dog 15,19 of lengthening additional.Because the pilot hole on pusher dog 10 waists is symmetrical, so as long as can implement to proofread and correct to the dress axostylus axostyle, also can process pipe deformation, the top is replaced by as Fig. 7, Fig. 8 structure and is got final product.Just can demonstrate one-object-many-purposes through above-mentioned distortion with after changing accessory, many combinations have demonstrated fully practical and field operation characteristics easily.
