In the figure: 1. a piston cylinder matrix; 2. a blind rivet sub-body; 201. the piston body is internally provided with a pull nail; 202. a rivet gun piston parent body; 203. a limiting part; 3. a two-position four-way reversing valve; 401. a rivet core; 402. hollow rivet head.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
A primary and secondary cylinder extension and retraction device, as shown in fig. 1, comprising: the piston cylinder parent body 1 to and along the reciprocating sliding arrangement's in the piston cylinder parent body 1 blind rivet daughter 2. The blind rivet daughter 2 comprises an inner blind rivet piston daughter 201 and a rivet gun piston parent 202, the rivet gun piston parent 202 is slidably arranged in the first piston cylinder parent 1, and the rivet gun piston parent 202 and the first piston cylinder parent 1 are coaxially arranged. A buffer sealing ring is arranged between the piston cylinder matrix 1 and the rivet gun piston matrix 202, so that a rod cavity and a rodless cavity of the piston cylinder matrix 1 form an independent sealing cavity.
The blind rivet daughter 2 includes interior blind rivet piston daughter 201 and riveter piston parent 202, interior blind rivet piston daughter 201 can be followed the inside slip of riveter piston parent 202, be provided with the buffering sealing washer between interior blind rivet piston daughter 201 and riveter piston parent 202. The free end of the rivet gun piston body 202 is provided with a limiting portion 203, and the free end of the rivet gun piston body 202 is configured to limit the hollow rivet head 402. The left end of the inner blind rivet sub-body 2 is used for clamping a rivet core 401 of a rivet.
The device is provided with a two-position four-way reversing valve 3, wherein the two-position four-way reversing valve is connected with a rod cavity of the piston cylinder matrix 1 and a rodless cavity of the piston cylinder matrix 1, an initial station is (hereinafter also referred to as a first station), the rod cavity of the piston cylinder matrix 1 is in an exhaust state, and the rodless cavity of the piston cylinder matrix 1 is in an inflation state. When the rod cavity of the piston cylinder matrix 1 is in an exhaust state, the rodless cavity of the piston cylinder matrix 1 is in an inflation state, the pull nail daughter 2 is pushed leftwards, and the pull nail daughter 2 extends out of the piston cylinder matrix 1 to the maximum extent. Wherein second station behind the case reversal of two four-way reversing valve 3 does, piston cylinder parent 1 has the pole chamber to be in gas filled state, piston cylinder parent 1's no pole chamber is in the exhaust state, is that the blind rivet daughter 2 receives the thrust of pushing right promptly, and blind rivet daughter 2 is in furthest indentation in piston cylinder parent 1.
Through the effect of two four-way reversing valve 3, can make the blind rivet daughter 2 along the controllable flexible setting in the piston cylinder parent 1, when needing blind rivet daughter 2 indentation piston cylinder parent 1 at every turn, only need make two four-way reversing valve 3's case switching-over, make and be in the second station make piston cylinder parent 1 have the pole chamber to be in the gas filled state, piston cylinder parent 1's no pole chamber is in the exhaust state, then blind rivet daughter 2 can indentation piston cylinder parent 1 promptly. When the rivet sub-body 2 needs to extend out of the piston cylinder parent body 1, the valve core of the two-position four-way reversing valve 3 is reversed again to be positioned at the first station. The rod cavity of the piston cylinder matrix 1 is in an exhaust state, the rodless cavity of the piston cylinder matrix 1 is in an inflation state, and the blind rivet daughter 2 can extend out of the piston cylinder matrix 1.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
