Abstract
The utility model discloses a threaded stud assembling sleeve which is composed of a sleeve body and is characterized in that one end of the sleeve body is provided with a screwed hole, and the end of the screwed hole is provided with a steel ball hole; a steel ball is arranged in the steel ball hole, and the diameter of the steel ball hole is smaller than that of the steel ball; the interference fit is adopted between the steel ball and the steel ball hole, and the depth of the steel ball hole is smaller than the diameter of the steel ball; the other end of the sleeve body is provided with a circumscribed interface. The threaded stud assembling sleeve of the utility model is provided with the steel ball in the sleeve to realize the point contact between the end face of a threaded stud and the steel ball, thereby not only effectively avoiding the problem that taking down a sleeve locked on the threaded stud is difficult, but causing one-off assembly of the threaded stud to be realized, and greatly improving the assembly efficiency. The threaded stud assembling sleeve is especially adapted to the assembly of the threaded stud in the process of mass production.
Description
Technical field
The utility model relates to a kind of installation, dismounting assembly tool, the especially stud of installation or removal stud assembling sleeve.
Background technology
Stud is a kind of standard component, be widely used in installation between the machine components, fixing in; At present, known stud assembling is to load onto two nuts at its non-assembling end of thread, and they are locked mutually, nut realizes by turning, its weak point is also to need after the assembling two nuts of locking are mutually taken off, and therefore, efficiency of assembling is low especially; Some directly adopts clamp to clamp stud Assembly rail portion, though improved efficiency of assembling like this, stud bar portion is crushed; Also having at the non-assembling end of thread of stud adopts the assembling sleeve to improve efficiency of assembling, but, assembly force but will assemble sleeve and be locked on the stud, when backing out the assembling sleeve, stud also is unscrewed together or backs out, stud can not disposablely be seated, also can destroy the threaded engagement between stud and the screw.
Summary of the invention
The utility model is low or destroy the above-mentioned deficiency of screw thread between stud and the screw etc. when assembling at the stud efficiency of assembling of prior art, provide a kind of simple in structure, efficiency of assembling is high, the screw thread at stud two ends is all had the stud assembling sleeve of big protective effect.
The technical solution of the utility model: a kind of stud assembling sleeve, comprise sleeve body, it is characterized in that: the end in described sleeve body is provided with screwed hole, is provided with steel ball hole in the end of screwed hole, and steel ball is arranged in the steel ball hole; The diameter of steel ball hole is interference fit less than the diameter of steel ball between steel ball and the steel ball hole, and the degree of depth of steel ball hole is less than the diameter of steel ball; The other end in sleeve body is provided with external interface;
Further feature is: be provided with small through hole at the sleeve body middle part, the diameter of small through hole is less than the diameter of steel ball, and small through hole is communicated with screwed hole with external interface.
Stud assembling sleeve of the present utility model with respect to prior art, has following characteristics:
1, is provided with steel ball in the sleeve, realizes that the stud end face contacts with point between the steel ball.
2, not only avoid sleeve to be locked at being difficult on the stud problem of taking off effectively, made that stud is disposable to be seated, improved efficiency of assembling widely.
Even 3 under the situation of worn steel ball, also can realize the quick replacing of steel ball by the small through hole in the sleeve, guarantee that the stud end face contacts with point between the steel ball.
4, the stud that is particularly useful in the high volume production process assembles.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model sleeve and stud mounting structure front view;
Fig. 2 is sleeve body (part a 4) structural front view;
Fig. 3 is the left view of Fig. 2;
Fig. 4 is the right view of Fig. 2.
The specific embodiment
In Fig. 1,2,3,4,1-stud, 2-bolts assemblies end, 3-bolt abutting end, 4-sleeve body, 5-screwed hole, 6-steel ball hole, 7-steel ball, 8-small through hole, 9-external interface;
Stud assembling sleeve of the present utility model comprises sleeve body 4, and an end of sleeve body 4 is provided with screwed hole 5, is provided with steel ball hole 6 in the end of screwed hole 5, and steel ball 7 is arranged in the steel ball hole 6; The diameter of steel ball hole 6 is interference fit less than the diameter of steel ball 7 between steel ball 7 and the steel ball hole 6, and the degree of depth of steel ball hole 6 is less than the diameter of steel ball 7, after steel ball 7 is seated, and the bottom surface, hole that steel ball 7 protrudes screwed holes 5; The diameter of steel ball 7 should be not more than the diameter of stud 1; The other end in sleeve body 4 is provided with external interface 9, can be connected with pneumatic assembling rifle or other assembly tools of outside by external interface 9, drives its synchronous rotation by pneumatic assembling rifle or other assembly tools; Commonly used pneumatic assembling rifle or other assembly tools all are square knuckle, so that external interface 9 can be set to is square.
Be provided with a small through hole 8 at sleeve body 4 middle parts, the diameter of small through hole 8 is less than the diameter of steel ball 7, and small through hole 8 is communicated with screwed hole 5 with external interface 9; When steel ball 7 heavy wears, can take off easily and upgrade steel ball 7 by small through hole 8.
The screwed hole 5 of sleeve body 4 is complementary with the external screw thread of the bolt abutting end 3 of stud 1, cooperatively interacts and screws; The bolts assemblies end 2 of stud 1 matches with the screwed hole of parts to be connected.During assembling, rotate with pneumatic assembling rifle or the manual sleeve body 4 that drives, the screwed hole 5 of sleeve body 4 cooperatively interacts with the bolt abutting end 3 of stud 1 and screws, sleeve body 4 drives stud 1 and rotates in the same way, the rotary speed of sleeve body 4 is greater than stud 1, when the end face of bolt abutting end 3 touched steel ball 7 projecting surfaces, sleeve body 4 just drove stud 1 and rotates synchronously, assembling end 2 was fitted in the screwed hole of workpiece to be connected and put in place; Make the reverse rotation of pneumatic assembling rifle, sleeve body 4 reverse sync is thereupon rotated, or manual drive sleeve body 4 reverse rotations, because the end face of bolt abutting end 3 and the some contact force between steel ball 7 projecting surfaces are far smaller than the assembly force between assembling end 2 and the workpiece hole, sleeve body 4 is taken off from bolt abutting end 3 at once.
