Abstract
The utility model discloses a dedicated sleeve for a stud bolt, which is used for preventing steel balls from dropping and locking. The dedicated sleeve comprises a sleeve body and steel balls; the upper end of the sleeve body is provided with a square prism hole which is matched and connected with an air wrench square prism; and the lower end of the sleeve body is provided with a sleeve internal thread hole. A thread bushing is internally arranged in the sleeve internal thread hole and is provided with an internal thread and an external thread; the external thread of the thread bushing is matched with the internal thread of the thread bushing; the steel balls are arranged on the upper end of the thread bushing; the internal thread of the thread bushing is matched with one end of the stud bolt; the lower end of the thread bushing is extended outside the sleeve body; and the extended part of the lower end of the thread bushing is provided with a loading and unloading surface. The dedicated sleeve not only can meet the requirement of tightening the stud bolt, also can prevent the steel balls from dropping and the stud bolt and the sleeve in the existing sleeve from locking, avoids the situation that the stud bolt can not be unscrewed on the sleeve, prolongs the service life of the sleeve and saves the cost.
Description
Technical field
The utility model relates to a kind of sleeve, specifically is a kind of socket wrench specially adapted for it that screws stud is installed on a kind of machine-building assembly line.
Technical background
At present, a large amount of stud socket wrench specially adapted for it that use are that an a kind of end has prismatic hole, a four directions on the known assembly line, and the other end has a screwed hole, and a steel ball are fixed on the structure of screwed hole bottom with copper sheathing.Sleeve is contained on the pneumatic impact spanner, simultaneously in the screwed hole of a precession sleeve of stud, steel ball on the top, again the other end of stud is aimed at by the screwed hole of dress body, start pneumatic impact spanner, the rotation of drive sleeve, stud is tightened onto by in the screwed hole of dress body, and at this moment, the stud one termination portion that is connected with sleeve withstands on the steel ball, only a bit contact, and the other end and the effect that is reached stressed joint by dress body screwed hole, so the reverse rotation sleeve will separate sleeve and stud, stud is stayed by on the dress body, seen Fig. 1.But, in real work, have unfavorable factors such as vibrations, impact, high speed rotation, so steel ball comes off easily, the easy abrasion deformation of tooth or destroyed at the bottom of the screw thread, thereby can occur stud effectively can not being tightened onto by in the dress body screwed hole or the revolution sleeve stud is screwed out by dress body screwed hole and stud in the sleeve inward turning not down, cause sleeve brief service life, increase cost, bring very big influence also can for efficiency of assembling, the result of use of product facility.
The utility model content
In order to overcome the technical problem that existing stud socket wrench specially adapted for it exists, the purpose of this utility model is to provide a kind of stud socket wrench specially adapted for it, it both can satisfy the requirement that screws stud, can prevent that again steel ball from coming off, prevent in the existing sleeve stud and sleeve locking and stud on sleeve, do not twist situation.
The utility model is the technical scheme that its purpose of realization is taked: a kind of stud socket wrench specially adapted for it: comprise sleeve body and steel ball, described sleeve body upper end is provided with the cubic prismatic hole that is connected with pneumatic impact spanner four directions prism, described sleeve body lower end is provided with the internal thread of sleeve hole, a built-in thread bush in the described internal thread of sleeve hole, described thread bush is provided with internal thread and external screw thread, the external screw thread of thread bush cooperates with described internal thread of sleeve hole, described steel ball is positioned at the thread bush upper end, and the internal thread of thread bush cooperates with an end of stud.Stretch out outside the sleeve body described thread bush lower end, and the extension of thread bush lower end has parallel surface.
The beneficial effects of the utility model: can not only satisfy the requirement that screws stud, can also prevent that steel ball from coming off, prevent in the existing sleeve stud and sleeve locking and stud on sleeve, do not twist situation, increased service life of sleeve, saved cost.

Among the figure 1, pneumatic impact spanner 2-1, rubber back-up ring 2-2, latch 3, sleeve body 4, copper sheathing 5, steel ball 6, stud 7, adorned body 8, thread bush 8-1, thread bush external screw thread 8-2, steel ball hole 8-3, thread bush internal thread 8-4, loading and unloading face
Specific embodiment
The utility model is the improvement to the stud socket wrench specially adapted for it that uses on the existing assembly line.Stud socket wrench specially adapted for it work schematic diagram of the present utility model shown in Figure 2, it comprises sleeve body 3, steel ball 5, described sleeve body 3 upper ends are provided with cubic prismatic hole, are connected by rubber back-up ring 2-1 and latch 2-2 and pneumatic impact spanner 1 cubic prism.Described sleeve body 3 lower ends are provided with the internal thread of sleeve hole, a built-in thread bush 8 in the described internal thread of sleeve hole, described thread bush is provided with internal thread 8-3 and external screw thread 8-1, the external screw thread 8-1 of thread bush 8 cooperates with described sleeve 3 internal thread holes, described steel ball 5 is positioned at thread bush 8 upper ends, and the internal thread 8-3 of thread bush cooperates with an end of stud 6.Stretch out outside the sleeve body 3 described thread bush 8 lower ends, and the extension of thread bush 8 lower ends has two the loading and unloading face that is parallel to each other 8-4, is convenient to load and unload thread bush 8, referring to Fig. 3,4.
The course of work: sleeve body 3 is contained on the pneumatic impact spanner 1, simultaneously the internal thread hole 8-3 of a precession thread bush of stud, described steel ball 5 is fixed in the steel ball hole 8-2 of thread bush 8 bottoms by sleeve body 3 and being threaded of thread bush 8, steel ball 5 is fixed on the problem with regard to not occurring coming off in the 8-2 of steel ball hole like this, again the other end of stud 6 is aimed at by the screwed hole of dress body 7, start pneumatic impact spanner 1, drive sleeve body 3 rotations, thread bush 8 is tightened onto stud 6 by in the screwed hole of dress body 7, when stud and thread bush 8 lockings influence stud revolve tight or stud when not twisting on the sleeve body 3, thread bush 8 makes steel ball 5 occur becoming flexible as long as circle round, and just can easily solve the locking problem.This moment, the Bottom of Thread of sleeve body 3 can not be subjected to big wearing and tearing and damage, was the Bottom of Thread infringement of thread bush 8 even damage yet, and only needed to change thread bush 8 and get final product, had not only made things convenient for but also saved cost.
The utility model has solved the problem that steel ball comes off easily in the prior art, has also solved the problem of stud and the locking of sleeve body ease of connection.
