Description

A kind of practical sleeve
Technical field
The utility model relates to box spanner technical fields, more particularly to a kind of practical sleeve.
Background technique
In engine production assembling process, the utilization rate of bolt is very high.Generally use the method pair that air gun adds sleeve Bolt is tightened, and tightens efficiency to improve bolt.In the actual operation process, single station needs to install a variety of different rulers Very little bolt, it is necessary to which the sleeve for replacing adaptation is bolted on.The method frequently replaces sleeve and wastes a large amount of time.
In existing patented technology, a kind of above-mentioned technology of double end sleeve (application number 201610754629.4) solution is provided and is asked Topic.The connection of the sleeve and spanner of the patent is not by fixing, not Portable belt and operation.
Utility model content
The utility model aim is to propose that a kind of structure is simple, transformation is convenient, ensures sleeve and spanner connection reliability.
Preferably, the utility model can also have following technical characteristic:
A kind of practical sleeve, including the body of rod, the body of rod both ends are equipped with hexagon pullover, and connection pneumatic tool turns The square attaching apertures of axis;The pullover small one and large one;The connecting hole is located at the bottom of the pullover;The body of rod, pullover, company Hole three's central coaxial is connect, the body of rod is in a circular table shape;The side wall of the connecting hole offers the ladder along the body of rod radial direction Hole;The stepped hole is through-hole, interior to be equipped with elastic telescopic device;The elastic telescopic device includes spring, mobile jib, fixation Confined planes are extended in the side of piece, the mobile jib both ends, for limiting the collapsing length of the mobile jib;During the fixinig plate is equipped with Heart perforation;The mobile jib is arranged in the stepped hole by the spring, and the fixinig plate is located at the stepped hole Outer end.
Further, the fixinig plate is threadedly coupled with the ladder outer end of hole.
Further, the end that the mobile jib stretches out outside stepped hole is hemisphere face.
Further, the lateral wall of the pullover is equipped with grid annular knurl.
Further, the lateral wall of the pullover is symmetrically arranged with flat position.
Further, the limit inferior deviation of the pullover and the connecting hole is+0.1, and upper end is+0.5.
Further, the outer end of the connecting hole offers chamfering.
The beneficial effect that the utility model is compared with the prior art includes:
(1) double end sleeve is long compared to the length of single sleeve, and weight is big, and common connection spanner can not effectively connect solid Determine double end sleeve, sleeve is caused to drop out from wrench adapter, unnecessary negative effect is caused for production, therefore, to ensure to pull The elastic device of the connection reliability of hand and sleeve, spanner card column sleeve need to further extend, and card column is unfavorable for after extending Extract sleeve;The utility model opens up chamfering by the outer end in connecting hole, protrudes into convenient for spanner;Elastic telescopic device is set again The card column for squeezing spanner extracts sleeve after so that card column is shunk certain length again, can so improve the use quality of double end sleeve.
(2) in the limited assembly space of engine, the arrangement of bolt and the size of bolt are related, and the utility model passes through Using the body of rod of boss-shaped, reduce the lateral thickness of small pullover, provides space to tighten bolt.
Detailed description of the invention
Fig. 1 is the utility model perspective view;
Fig. 2 is the utility model section figure;
Fig. 3 is the utility model top view;
Fig. 4 is the utility model bottom view;
Fig. 5 is enlarged drawing at the A of Fig. 2.
Specific embodiment
With reference to embodiment and compares attached drawing the utility model is described in further detail.It should be emphasized that It is that following the description is only exemplary, rather than in order to limit the scope of the utility model and its application.
Referring to the following drawings, non-limiting and nonexcludability embodiment will be described, wherein identical appended drawing reference indicates Identical component, unless stated otherwise.
A kind of practical sleeve as shown in Figs. 1-5, including the body of rod 5,5 both ends of the body of rod, which are equipped with, packs into positive the six of bolt Angular pullover (1,11), and the square connecting hole 4 of connection pneumatic tool shaft.The pullover small one and large one, be adapted to respectively The different bolt of size.The connecting hole 4 is located at the bottom of the pullover, and the junction of connecting hole 4 and pullover is equipped with chamfering. The body of rod 5, pullover (1,11), 4 three's central coaxial of connecting hole.The body of rod 5 is in a circular table shape, and big portion is equipped with big pullover 1, Small portion is equipped with small pullover 11.The side wall of the connecting hole 4 is offered along the radial stepped hole 2 of the body of rod 5, the stepped hole 2 For through-hole, it is inside additionally provided with elastic telescopic device, for squeezing the card column of spanner, improves the service performance of sleeve and spanner.Institute Stating elastic telescopic device includes spring 23, mobile jib 24, fixinig plate 21, and confined planes are extended in the side at the both ends of the mobile jib 24 (22,25), two confined planes it is of different sizes, for limiting the collapsing length of the mobile jib 24.During the fixinig plate 21 is equipped with Heart perforation, the diameter of the perforation is slightly larger than the diameter of mobile jib 24, and is equipped with external screw thread in its side, and the outer end of stepped hole 2 is equipped with Matched internal screw thread.
Spring 23 is placed in stepped hole 2 by the assembly of elastic telescopic device, and mobile jib 24 protrudes into stepped hole 2 and pierces into spring 23, so that the confined planes 25 of 24 lower end of mobile jib is abutted the cascaded surface of stepped hole 2, the confined planes 22 of upper end and the end face of spring 23 connect Touching;Then fixinig plate 21 is penetrated into mobile jib 24, and is tightened on the outer end of stepped hole 2.
