Abstract
The utility model discloses a reversely-unscrewing-type chuck which comprises a thread sleeve and a mandril. An internal threaded through hole is formed in the cone-shaped end portion at the bottom of the thread sleeve, an internal cavity is arranged in the thread sleeve, and the internal cavity and the internal threaded through hole share a center shaft and are communicated. The mandril is composed of a mandril base and a mandril body, wherein an internal threaded through hole used for allowing a stud to penetrate into is formed in the end portion of the mandril body, and when the mandril and the thread sleeve are assembled into a whole, the mandril body of the mandril is inserted into the internal cavity of the thread sleeve, and the mandril body is matched with the internal cavity of the thread sleeve in a threaded mode. When the chuck is matched with a blower gun in use, the stud can be conveniently and quickly disassembled, and working efficiency is greatly improved.
Description
Technical field
The utility model relates to studs detaching device field, is specially a kind of counter-rotating and withdraws from the formula dop.
Background technology
In the various plant equipment, coming fastening or connect each parts of machine with studs is modal things.But in the installation or maintenance process of machinery equipment, also often need to dismantle for a certain reason studs.What people adopted usually in the prior art is that double nut is pieced together tight method and some other methods (such as direct destruction studs, with pliers it being back-outed) are dismantled studs.Double nut is pieced together tight method and is used common wrench (needing two spanners), first two nuts are screwed to one by one an end of studs, and with two spanners two nuts are locked relatively, nut can not be rotated relative to double-screw bolt, and then pull nut with spanner, double-screw bolt is pulled down, again two nuts are screwed down one by one afterwards.This method of operating step is very loaded down with trivial details, and the speed of tightening is slow, and labour intensity is large, and work efficiency is very low.
The utility model content
The utility model purpose provides a kind of counter-rotating and withdraws from the formula dop, cooperates air pressure gun to use, to solve prior art studs method for dismounting complex steps, the problem that work efficiency is lower.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
The formula dop is withdrawed from counter-rotating, include the swivel nut that is assembled into one, plug, it is characterized in that: described swivel nut bottom has tapered end, have the internal thread through hole that screws in for studs in the tapered end, also have the inner chamber that inwall forms levogyrate inner thread from the swivel nut top to swivel nut, and inner chamber is total to central shaft with the internal thread through hole of swivel nut tapered end and is communicated with, described plug is made of rod seat and the excellent body that is connected on the rod seat, wherein form the internal thread through hole that stretches into for studs in the excellent body end, rod body outer wall forms the sinistral external thread with swivel nut inner chamber levogyrate inner thread coupling, when described plug and swivel nut are assembled into one, the excellent body of plug inserts in the swivel nut inner chamber, and plug rod body cooperates with the swivel nut thread in inner cavity.
The formula dop is withdrawed from described counter-rotating, it is characterized in that: also have slotted hole on the described swivel nut, be provided with the straight pin that can stretch in the swivel nut inner chamber in the slotted hole.
The formula dop is withdrawed from described counter-rotating, it is characterized in that: described plug rod is provided with through hole with it.
The formula dop is withdrawed from described counter-rotating, it is characterized in that: the rod seat end of described plug is shaped to 1/2 square toes form.
The formula dop is withdrawed from described counter-rotating, it is characterized in that: it is hexagonal column that described swivel nut is shaped to the cross section.
When the utility model and air pressure gun are used, only need two rifles just can pull down studs, in the situation of not destroying studs, can conveniently pull down studs, greatly improved work efficiency.

Fig. 3 is the utility model mandrel structure cutaway view.
The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3.The formula dop is withdrawed from counter-rotating, include the swivel nut 1 that is assembled into one, plug 2, swivel nut 1 bottom has tapered end 3, have the internal thread through hole 4 that screws in for studs in the tapered end 3, also have the inner chamber 5 that inwall forms levogyrate inner thread from swivel nut 1 top to swivel nut, and inner chamber 5 is total to central shaft with the internal thread through hole 4 of swivel nut 1 tapered end 3 and is communicated with, plug 2 is made of rod seat 6 and the excellent body 7 that is connected on the rod seat 6, wherein form the internal thread through hole that stretches into for studs in excellent body 7 ends, rod body 7 outer walls form the sinistral external thread with swivel nut inner chamber levogyrate inner thread coupling, when plug 2 is assembled into one with swivel nut 1, the excellent body 7 of plug 2 inserts in swivel nut 1 inner chamber 5, and plug 2 rod bodies 7 and swivel nut 1 inner chamber 5 threaded engagement.
Also have slotted hole 8 on the swivel nut 1, be provided with the straight pin 9 that can stretch in swivel nut 1 inner chamber in the slotted hole 8,, it is hexagonal column that swivel nut 1 is shaped to the cross section.Also be provided with through hole 10 on the plug 2 rod bodies 7, rod seat 6 ends of plug 2 are shaped to 1/2 square toes form.
The utility model is for convenient and is connected the spanner of inch output and connects, and rod seat 6 ends of plug are shaped to 1/2 square toes form, and the promising sinistral external thread of excellent body outer wall moulding of plug, rod be a through hole in addition with it.Be provided with inner chamber in the supporting swivel nut of plug, cavity wall forms levogyrate inner thread in the swivel nut, and form the internal thread through hole that can cooperate with various studs in the swivel nut tapered end, it is hexagonal column that the swivel nut shape is shaped to the cross section, purpose is can utilize other instruments that it is tightened when the dismounting studs, increase its resistance, prevent that air pressure gun from rotating moment swivel nut transfer.It is stroke that while the utility model utilizes the relative rotation of controlling plug and swivel nut of straight pin, and prevents that with it plug and swivel nut from coming off, and also having an effect is exactly that band turns swivel nut.
General studs is right-handed thread, when studs is contained on the equipment, the exposed junction of the utility model swivel nut tapered end internal thread through hole and studs is screwed, and block swivel nut with open-end wrench, air pressure gun turns left, the plug rod namely can withstand studs and expose the termination in swivel nut, and with its chucking.Take open-end wrench this moment away, and air pressure gun turns left, and can pull down studs, and after studs was pulled down from machine or equipment, air pressure gun was turned right, and unscrews plug and studs.
