Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.The example of these preferred implementations is illustrated in the accompanying drawings.The embodiment of the present utility model shown in accompanying drawing and described with reference to the accompanying drawings is merely exemplary, and this utility model is not limited to these embodiments.
As it is shown in figure 1, be the beche schematic diagram of prior art, prior art is promoted drift to drive pneumatic red needle 5 to link by air inlet, being thered is provided buffering by spring 20 and drive motion drift backhaul reciprocal, because operating frequency is high, spring is fragile, causing production efficiency low, impulsive force is little and adjustable amplitude is little.
nullSuch as Fig. 2、Shown in Fig. 3，Beche of the present utility model includes body 1，This external housing 2，Body interior is formed with cavity 3，Motion drift 4 it is provided with in cavity、It is arranged at the pneumatic red needle 5 of body bottom portion、And connect air inlet pipeline 22 and the air vent 6 of cavity，Described cavity is divided into upper chamber 7 and lower cavity 8，The area of upper chamber 7 cross section is more than the area of lower cavity 8 cross section，Upper chamber 7 and lower cavity 8 junction form step-like boss 24，The air inlet 9 of described air inlet pipeline 22 is set to be connected with upper chamber 7，Air vent is set to be connected with lower cavity 8，The described shape of motion drift top piston 10 matches with the cross section of upper chamber 7 to merge and forms the upper cylinder 12 of opposing seal with case top 14，The shape of motion ram bottom piston 11 matches with the cross section of lower cavity 8 and merges and the lower cylinders 13 of motion drift top formation opposing seal，The top piston of motion drift is connected by connecting rod 15 with bottom piston，The bottom piston of motion drift is additionally provided with the passage 23 can being connected respectively with upper cylinder 12 and air vent 6，And be connected with upper cylinder 12 by the passage 16 within connecting rod.
Preferably, in this utility model, the bottom piston of motion drift includes the piston that two difference are setting up and down, upper piston 17 and lower piston 18, the edge of upper piston 17 is provided with the passage for connecting with upper cylinder 12, and the edge of lower piston 18 is provided with and can be used for air vent 6 to the passage 23 connected.Described upper chamber 7 and lower cavity 8 are cylinder.Described air inlet pipeline 22 is arranged between the outer wall of housing and inwall.Described air inlet pipeline is the circular passage being arranged between housing exterior walls and inwall.The discharge directions of described air inlet 9 is straight up.Described beche also includes the connection lid being arranged at body top, and the air inlet pipeline that is internally provided with connecting lid 21 is connected with intrinsic air inlet pipeline.Described beche also includes the deafener 19 being arranged at body bottom portion.The described lid 21 that connects is additionally provided with circular groove.Described housing is provided with the flat position formed through Milling Process, and described housing bottom is provided with the groove milling of machined formation.
Specific works principle, see Fig. 3, original state, air inlet enters lower cylinders 13 by air inlet pipeline 22 by air inlet 9, act on motion drift top piston 10 to move upward, when the passage arranged when upper piston 17 edge moves to be connected with lower cylinders 13, lower cylinders 13 is connected with upper cylinder 12, and the pressure P2 of upper cylinder 12 is equal with the pressure P1 of lower cylinders 13.As P1=P2, from F=P*S, the active area of motion drift top piston 10 is far longer than the area of boss 24, so, act on the directed force F 2 of motion drift top piston 10 much larger than the active force acting on bottom boss 24, this brief acceleration is reverse, but due to inertia, motion drift also can move upward a segment distance, until speed is kept to 0, start to move downward, when the passage arranged when lower piston 18 edge moves to be connected with air vent 6, upper cylinder 12 drain pressure reduces, complete one-shot, motion drift is returned to initial position, restart subsequent cycle.
It addition, when the circular grooves connecting lid 21 setting can prevent work and landing between handle of a knife；The flat position of housing is easy to assemble assembling；The groove milling of housing bottom is for alleviating weight, thus reaches operationally to reduce overall impulsive force purpose.
It is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should be using description as an entirety, technical scheme in each embodiment can also form, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that.
The a series of detailed description of those listed above is only for illustrating of the feasibility embodiment of the application; they are also not used to limit the protection domain of the application, within all equivalent implementations made without departing from the application skill spirit or change should be included in the protection domain of the application.
