The utility model content
The technical matters that the utility model solves is: a kind of pick-up unit that simply, can detect the sealing property of variator signaling switch efficiently is provided.
The technical scheme of the utility model is: a kind of pick-up unit of variator signaling switch; It is characterized in that, comprise fuel tank, the two relative side of fuel tank is fixed with piston cavity and supporting base respectively; The inner chamber of piston cavity communicates with the inner chamber of fuel tank; Be provided with piston in the inner chamber of piston cavity, said supporting base is provided with the pilot hole that runs through, and being inserted with one in this pilot hole can axially movable screw rod; This screw flight end extends the outside and sheathed nut of fuel tank from said pilot hole, and the other end of screw rod passes the inner chamber of fuel tank and fixes with said piston; The end face of fuel tank is provided with at least one threaded perforations that is used to install the wheel box signaling switch.
Said fuel tank is provided with tensimeter, and this manometric sounding rod extend in the inner chamber of fuel tank.
Be provided with rubber seal between said piston and the said piston cavity.
Be provided with rubber seal between the pilot hole of said screw rod and said supporting base.
The shell wall of said fuel tank is provided with purge cock.
Be provided with sealing gasket between the faying face between said piston cavity and the said fuel tank.
Be provided with plain washer between said nut and the said fuel tank outer wall.
The beneficial effect of the utility model is: when the utility model uses; In the inner chamber of fuel tank, all fill with oil in the inner chamber of piston cavity, the variator signaling switch that needs are detected is installed in the threaded perforations that is used for installing the wheel box signaling switch of fuel tank end face, is positioned at the nut of fuel tank outside, screw rod end with the spanner rotation; Nut drives screw axial and outwards moves; Screw rod drives piston and moves towards the interior cavity direction of fuel tank in moving process, oil is compressed the generation normal pressure in this moment fuel tank, and the oil with normal pressure is pressed to the wheel box signaling switch through threaded perforations; Thereby accomplish the oil seal test of wheel box signaling switch; The utility model is simple in structure, and is easy to use, can be fast the sealing property of variator signaling switch be detected; Filter out underproof variator signaling switch, guaranteed the reliability of variator signaling switch performance.
