CN2467316Y - Hydropress with positioning buffer unit - Google Patents

Abstract

The utility model relates to a hydropress with positioning and buffering units, which is characterized in that a positioning and buffering unit composed of a worm gear box, a shaft coupler, a shaft, a speed reducer, a movable sleeve, a leading screw, a buffering cylinder is arranged between a sliding block and an upper cross beam of a hydropress. The utility model has the advantage and the active effect that as the positioning and the buffering functions are integrated together, under the condition of the high precision of the complete hydropress, the utility model has the advantages of small ground occupation, convenience machining, and machining cost lowering.

Description

Have the hydraulic press of locating buffer unit

The utility model belongs to the tower structure hydraulic press, particularly relates to a kind of hydraulic press of locating buffer unit that has.

On the present known hydraulic press or have positioning function or have pooling feature, also promptly only have a kind of function wherein, therefore exist deficiency to be, not only the machine floor space is big, but also processing inconvenience and processing cost height,

The purpose of this utility model be to overcome the deficiency in the known technology and provide a kind of guarantee both to be convenient to process under the high situation of complete machine precision possess the range of work wide have a hydraulic press of locating buffer unit.

The purpose of this utility model is achieved in that

The utility model is by install sill on basic table top, the travelling table that has mould is installed on the sill, the both sides of sill respectively are installed on it by positioning sleeve the pillar of guide rail are housed, on pillar, the entablature that has oil cylinder is installed by positioning sleeve, oil cylinder even is equipped with slide block, on the basis that is coated with the stretching screw composition between entablature and sill and the pillar, be to realize the purpose of this utility model like this: the location buffer unit is housed between slide block and entablature, it specifically constitutes, plane four ends respectively are fixed with worm gear case on entablature, and every worm screw all even is equipped with axle and formation by shaft coupling in four worm gear cases

Shape is constituting The bottom of shape is formed by reductor is housed between diaxon, worm engaging in each worm gear case has worm gear, worm gear is installed quill by key, and quill is by the nut leading screw of packing into, leading screw stretch out entablature and the cushion dashpot that is equipped with thereon after be loaded on slide block by nut again.

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the horizontal layout schematic diagram of location buffer unit in the utility model among Fig. 1;

Fig. 3 is the concrete structure schematic diagram of location buffer unit among Fig. 1.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

With reference to Fig. 1, sill 1 is packed on the basic table top, the travelling table 2 that has mould is installed on the sill, the pillar 3 that respectively is installed on it guide rail is housed by positioning sleeve on the both sides of sill, on pillar, the entablature 5 that has oil cylinder 19 is installed by positioning sleeve, oil cylinder even is equipped with slide block 4, between entablature and sill and pillar, be coated with stretching screw and form frame structure, slide block and entablature by its structure are equipped with the location buffer unit, its concrete formation is, with reference to Fig. 2 and Fig. 3, respectively be fixed with in 9, four worm gear cases of worm gear case every worm screw 11 at plane four ends on the entablature 5 and all connect and axle 6 is housed and constitutes by shaft coupling 17 Shape is constituting The bottom of shape is formed by reductor 8 is housed between diaxon, worm engaging in each worm gear case has worm gear 16, worm gear is installed quill 15 by key 14, quill is by nut 12 leading screw 7 of packing into, leading screw stretch out entablature 5 and the cushion dashpot 10 that is equipped with thereon after be loaded on slide block 4 by nut 13 again.

After connecting power supply, driving axle 6 by reductor 8 rotates, drive worm screw 11 rotations by shaft coupling 17 again, worm screw drives worm gear 16 rotations again, worm gear drives quill 15 rotations by key 14, quill drives leading screw 7 by nut 12 and moves up and down, and makes the utility model reach the purpose that the location is adjusted like this.When needs played cushioning effect, after cushion dashpot 10 oilings, slide block drove leading screw and moves downward, and when arriving leading screw and adjusting the position, nut 12 contact with the movable piston face of cushion dashpot, and cushion dashpot begins descendingly at this moment, and the pressure of cushion dashpot is controlled by proportioning valve 18.Make the utility model can reach the purpose that the location is adjusted again like this.

Advantage and the good effect that the utlity model has are, because in the utility model Installed positioning buffer unit additional, made the location and cushion two kinds of functions to be integrated in one, therefore existed Guarantee in the high situation of complete machine precision that it is little and processing is convenient and reduce and add to have floor space The characteristics of worker's cost.
