Abstract
The invention discloses a sleeve convenient to closely connect workpieces. The sleeve comprises a sleeve body (1), wherein the sleeve body (1) is a hollow circular column, the upper end of the sleeve body (1) outward protrudes so as to form a ring (2), the side wall of the sleeve body (1) is provided with an opening (3), and the opening (3) penetrates through the upper and lower ends of the sleeve body (1). The sleeve provided by the invention adopts the structure, the workpieces and the sleeve body (1) are easy to finish interference fit, and the close connection of the workpieces is realized.
Description
Technical field
The present invention relates to a kind of sleeve, specifically a kind of close-connected sleeve of workpiece of being convenient to.
Background technique
For the tight connection of workpiece, general what adopt is interference fit, when the diameter that deducts axle when the diameter in hole is negative, is referred to as interference, and the minimum limit of size that deducts axle when the upper limit size in hole is when being negative, and this cooperation just is called interference fit.Finish interference fit, what often adopt is " hot charging ", and " hot charging " is exactly that sleeve is added thermal expansion, and workpiece is cooled off contraction, then both are connected together rapidly, after recovering normal temperature, both have namely realized interference fit, have reached close-connected effect.But it is pretty troublesome to operate like this, simultaneously, if grasp expanding with heat and contract with cold bad, probably make be difficult to realize being full of cooperating or the interference fit effect bad, do not reach close-connected requirement.
Summary of the invention
Technical problem to be solved by this invention is to provide operation to use a kind of close-connected sleeve of workpiece of being convenient to of simple, tight good connecting effect.
The present invention is that the technical solution problem is achieved through the following technical solutions: a kind of close-connected sleeve of workpiece of being convenient to, comprise sleeve body, sleeve body is hollow cylinder, the upper end of sleeve body outwards convexes to form annulus, the sidewall of described sleeve body is provided with opening, and opening runs through the upper and lower end of sleeve body.
Described opening parallels with the center line of sleeve body.
The width of described opening be sleeve body the inwall circumference 1/100 ~ 1/20.
The width of described opening be sleeve body the outer wall circumference 1/100 ~ 1/20.
Being shaped as of described opening is square or trapezoidal.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) the present invention is provided with an opening on the basis of original sleeve, and opening can play the effect of fine setting, and after the bigger workpiece of caliber inserted sleeve, the contraction of sleeve formed an interference fit with self and workpiece, finishes tight connection.
(2) working procedure of the present invention is compared former interference fit, operates simplyr, does not need to consider that workpiece is connected with sleeve to expand with heat and contract with cold can finish tight connection, and is practical.
Description of drawings
Fig. 1 is plan view of the present invention;
Fig. 2 is plan view of the present invention;
Fig. 3 is side view of the present invention.
Corresponding reference character is in the accompanying drawing: 1, sleeve body, 2, annulus, 3, opening.
Embodiment
The present invention is described in further detail below in conjunction with embodiment, but embodiments of the present invention are not limited to this.
Embodiment:
Such as Fig. 1, Fig. 2 and shown in Figure 3, the present invention includes sleeve body 1, sleeve body 1 is hollow cylinder, the upper end of sleeve body 1 outwards convexes to form annulus 2, the sidewall of described sleeve body 1 is provided with opening 3, and opening 3 runs through the upper and lower end of sleeve body 1, and opening 3 parallels with the center line of sleeve body 1, when like this workpiece being inserted sleeve body 1, expansion effect is good; The width of opening 3 is 1/100 ~ 1/20 of the inwall circumference of sleeve body 1 or outer wall circumference, and certain A/F can guarantee preferably interference fit effect; Being shaped as of opening 3 is square or trapezoidal, conveniently like this inserts fastener at opening 3, makes the caliber of sleeve body 1 can satisfy the insertion requirement of workpiece.
Working principle of the present invention is: at first, pipe diameter size according to workpiece, select suitable fastener and it is inserted on the opening 3, workpiece to be connected is inserted in the sleeve body 1, then take off fastener, under the contraction of sleeve body 1, workpiece and sleeve body 1 have namely been finished interference fit like this.
As mentioned above, then can realize well the present invention.
