Description
Technical field:
The utility model belongs to the frock technical field on machining equipment, is specifically related to a kind of hydraulic expanding covering device for cylinder barrel locating and machining.
Background technology:
At present, inner cylinder manufacturer of state all processes with cylinder barrel excircle orientation in the processing of cylinder barrel total length and car weld bond process, with the processing of cylinder barrel excircle orientation weld bond, turning frame nest, again with frame nest for benchmark Internal Threading, sealing surface, because of benchmark disunity, cause internal diameter of cylinder and outer circles deviation larger, after cylinder barrel and cylinder bottom or flange welding, more can not ensure axiality requirement when client assembles with endoporus, cause and difficulty is installed or in Long-Time Service process, easily causes movable sealing leakage of oil or axle sleeve eccentric wear phenomenon.
Summary of the invention:
It is simple that the purpose of this utility model is to provide a kind of structure, and easy to use, can ensure cylinder barrel internal-and external diameter axiality, operating efficiency is high, the hydraulic expanding covering device of long service life.
The technical solution of the utility model is: a kind of hydraulic expanding covering device, it is characterized in that: main shaft left end is provided with the voussoir cooperatively interacted and ringfeder fixed by nut successively, by the piston of bearings, cylinder cap, main shaft right-hand member sets firmly one end that tailstock fixed cover connects guide rod fixed cover location guide, the other end of guide rod is positioned at the guide hole on the right side of cylinder cap, seal band is established to match with piston cavity in the middle part of main shaft, seam is established to match with piston cavity on the left of cylinder cap, the oil filler point that cylinder cap is provided with is connected with the cavity formed between piston and seal band, oil filler point is connected with hydraulic system by pipeline.
Owing to adopting technique scheme, during use, cylinder barrel is enclosed within ringfeder, hydraulic oil is injected the cavity formed between piston and seal band by hydraulic system by oil filler point, promote piston to run left, piston promotes ringfeder and also radially expands while voussoir runs left, by inner hole of cylinder by cylinder barrel fixation, thus ensure that the axle center of inner hole of cylinder is linearly consistent with the axle center of hydraulic pressure ringfeder, ensure that the perpendicularity of weld bond axiality and end face, thus there is structure simple, easy to use, cylinder barrel internal-and external diameter axiality can be ensured, operating efficiency is high, the advantage of long service life.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further details.
Accompanying drawing is the utility model structural representation.
Detailed description of the invention:
With reference to accompanying drawing, a kind of hydraulic expanding covering device, main shaft 8 left end is provided with by the fixing voussoir 11 cooperatively interacted of nut 1 and ringfeder 2 successively, the piston 3 supported by bearing 9, cylinder cap 4, main shaft 8 right-hand member sets firmly one end that tailstock fixed cover 7 connects guide rod fixed cover 6 location guide 5, the other end of guide rod 5 is positioned at the guide hole on the right side of cylinder cap 4, seal band 10 is established to match with piston 3 inner chamber in the middle part of main shaft 8, seam is established to match with piston 3 inner chamber on the left of cylinder cap 4, the oil filler point 12 that cylinder cap 4 is provided with is connected with the cavity 13 formed between piston 3 and seal band 10, oil filler point 12 is connected with hydraulic system by pipeline.
