For achieving the above object, the invention provides a kind of press fit device of small fan bush, it comprises the pressing bar with inner chamber, the knock-pin that can be in inner chamber longitudinally slides and be arranged on rotationally a pair of jaw in the pressing bar, the bottom of pressing bar offers the through hole that is connected with inner chamber, the outer hole of formation one and intracavity inter-connection on the outer edge surface of described pressing bar, each jaw has protuberance and is positioned at the carrier of protuberance below, described jaw has closed and opens two duties, under closure state, this carrier to jaw forms material receiving in the inner chamber of described pressing bar, lining is placed on the material receiving from outer hole; Described knock-pin is down sliding longitudinally, and the bottom of described knock-pin contacts to drive jaw with the protuberance of described jaw and opens.
Preferably, described protuberance is a curved surface, and the each point on this curved surface is from top to bottom gradually near another jaw.
Preferably, the inner chamber and the through hole that are positioned at the material receiving below form the pressing passage, and the aperture of this pressing passage is identical with the external diameter of lining.
The present invention adopts above structure to have the following advantages:
1, automatic equipment is adopted in location and installation, and registration is installed firmly;
2, disposable location and the fitting operation finished saved time.

Accompanying drawing 2 is jaw of the present invention first cutaway views when being in open mode.
Accompanying drawing 3 is jaw of the present invention second cutaway views when being in open mode.
In the accompanying drawing: 1, pressing bar; 11, inner chamber; 12, through hole; 13, outer hole; 2, knock-pin; 3, jaw; 31, protuberance; 32, carrier.
The specific embodiment
Below in conjunction with one of accompanying drawing 1-3 preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be those skilled in the art will recognize that protection scope of the present invention is made more explicit defining.
Shown in accompanying drawing 1-3, a kind of press fit device of small fan bush, it comprises the pressing bar 1 with inner chamber 11, the knock-pin 2 that can be in inner chamber 11 longitudinally slides and be arranged on rotationally a pair of jaw 3 in the pressing bar 1, the bottom of pressing bar 1 offers the through hole that is connected 12 with inner chamber 11, form an outer hole 13 that is connected with inner chamber 11 on the outer edge surface of described pressing bar 1, each jaw 3 has protuberance 31 and is positioned at the carrier 32 of protuberance 31 belows, described jaw 3 has closed and opens two duties, under closure state, this carrier 32 to jaw 3 forms material receiving in the inner chamber 11 of described pressing bar 1, lining is placed on the material receiving from outer hole 13; Described knock-pin 2 is down sliding longitudinally, and the bottom of described knock-pin 2 contacts to drive jaw 3 with the protuberance 31 of described jaw 3 and opens.
Described protuberance 31 is a curved surface, and the each point on this curved surface is from top to bottom gradually near another jaw 3.
The inner chamber 11 that is positioned at the material receiving below forms the pressing passage with through hole 12, and the aperture of this pressing passage is identical with the external diameter of lining.
In the embodiments of the invention:
A kind of press fit device of small fan bush, it comprises pressing bar 1, knock-pin 2 and a pair of jaw 3 with inner chamber 11.
The inner chamber 11 of pressing bar 1 comprises for the perforation of knock-pin 2 slips, for the side road of jaw 3 around the axis rotation of rotating shaft, the bottom of pressing bar 1 offers and the through hole 12 of boring a hole and being connected, and offers the outer hole 13 that is connected with inner chamber 11 on the outer edge surface of pressing bar 1.
A pair of jaw 3 symmetries are arranged in the pressing bar 1 rotationally, and can the rotate axis of moving axis of jaw 3 opens or closes.Each jaw 3 has protuberance 31 and is positioned at the carrier 32 of protuberance 31 belows, described jaw 3 has closed and opens two duties, under closure state, this carrier 32 to jaw 3 forms material receiving in the inner chamber 11 of described pressing bar 1, lining is fallen into to through hole 12 from inner chamber 11 under open mode.
Knock-pin 2 longitudinally slides in the inside of pressing bar 1.
In the phase I of knock-pin 2 ejection process, knock-pin 2 contacts with the protuberance 31 of jaw 3, and protuberance 31 is a curved surface among the present invention, and the each point on this curved surface is from top to bottom gradually near another jaw 3.Jaw 3 is opened in the process of knock-pin 2 down slidings gradually.
In the second stage ejection process of knock-pin 2, knock-pin 2 withstands lining and presses to small fan.
Operation principle of the present invention is as follows:
Jaw 3 is closure state, lining is placed into from outer hole 13 on the material receiving of jaw 3 formation, knock-pin 2 ejects downwards, driving jaw 3 opens, lining falls into the pressing passage from inner chamber 11, knock-pin 2 continues to eject downwards, and knock-pin 2 is against the upper surface of lining, with bush press-fit on small fan.
The present invention adopts above structure to have the following advantages:
