Description
Technical field
The utility model relates to a kind of forcing press, and is particularly a kind of with the connecting rod of forcing press and the device of ball screw locking.
Background technology
In the press technologies, adopt screw-threaded coupling device that connecting rod and ball screw are fixed, the screw-threaded coupling device of existing forcing press generally adopts the locking device of locking shell type, comprise lock sleeve, with the relatively-stationary connecting rod in slide position, ball screw etc., lock sleeve is symmetrically set with two, and be built in the connecting rod by cooperation respectively, adding man-hour, can be one also with Machining of Connecting Rod, ball screw through the external screw thread of its upper end with female connecting rod axially be set be connected, one adds long bolt passes the just left and right sides lock sleeve connection locking of two lock sleeves, to reach the purpose of screw thread between locking connecting rod and the ball screw.Its weak point is: because lock sleeve has only the fraction screw thread to contact with ball screw, so the screw-threaded coupling ability is difficult to reach designing requirement.
The utility model content
The purpose of this utility model provides a kind of screw-threaded coupling device of forcing press, makes its coupling mechanism force reinforcement, reliable lock.
The purpose of this utility model is achieved in that a kind of screw-threaded coupling device of forcing press, comprise slide block, ball screw and connecting rod, slide block and connecting rod position relative fixed, ball screw through the external screw thread of its upper end with female connecting rod axially be set be connected, described connecting rod bottom is provided with a cylindrical cavity, be fixed with the screw rod cover that matches with cylindrical cavity on the ball screw, the connecting rod lower end is provided with the gland of pushing down the screw rod cover, connecting rod, gland and screw rod cover are tightly connected between any two, at connecting rod, the binding site of gland and screw rod cover forms the toroidal cavity of a sealing; Be fixed with an oil cylinder on the slide block, be provided with shoe cream room in the oil cylinder, shoe cream room one end is provided with end cap, and end cap is provided with the high-pressure oil pipe that is communicated with between toroidal cavity and the shoe cream room, the shoe cream room other end plunger that has been threaded.
During the utility model work, in toroidal cavity and shoe cream room, be full of hydraulic oil, pass through rotary plunger, promoting plunger moves in shoe cream room, in shoe cream room, produce certain oil pressure, oil pressure is by the transmission of high-pressure oil pipe, between screw rod cover and gland, produce a pair of direction opposite effect power, pass to ball screw and connecting rod respectively, like this, when the normal press work of forcing press, just can reach the purpose of connecting rod and ball screw screw-threaded coupling, it is non-displacement each other, and coupling mechanism force is strong, reliable lock; When needs are adjusted height of packing compact, unclamp plunger screw, discharge oil pressure, the thread pitch between connecting rod and the ball screw just can reach normal condition, can easily realize regulating the purpose of height of packing compact.Therefore, the utility model can safety, be applied on the forcing press reliably.
Regulate and observe for convenient, shoe cream room is connected a Pressure gauge; By observing manometric pressure, can determine that whether needing to carry out pressure regulates, and show the numerical value in the pressure adjusting.
