Description

The structural improvement of tail stock

Technical field

The utility model relates to lathe twin axle tailstock when boring, tapping one-stop operation, the parallel twin shaft slippage of being continued to use, and design is upright twin shaft, oscilaltion state.

Background technology

Boring, tapping be in lathe operation indispensable important operation, especially for the boring of the different pitch-rows of same axis, tapping, can reach one step completed action, at present all also use parallel twin axle tailstock to carry out operation, early stage (as Fig. 1) is as the known technology of this case, it mainly is to utilize the twin axle tailstock to cooperate manual driving lever, utilize axle bed left and right sides transverse shift, can be to reach the conversion diaxon to the coherent boring in the different apertures of same working substance, the operation of tapping, thereafter, though the research and development (as Fig. 2) of automatic oil pressure parallel double shaft type tailstock are arranged though go up in operation simple and easy more rapidly, yet; In boring; during the tapping start because tailstock 1A still adopts parallel double boring axle sleeve 13A; (interior be drill 15A to tapping axle sleeve 14A; tooth attacking device 16A); cooperate automatic oil pressure to reach left and right sides transverse shift; so have careless slightly; drill 15A or tooth attacking device 16A are when automatic shift; a left side is hit in collision through regular meeting; the avris of right knife rest 7A; cause operational inconvenience and puzzlement; even produce dangerous; unless; 1A elongates least significant end with tailstock; but so increase drill 15A; the stroke of tooth attacking device 16A and working substance is wasted man-hour and manufacturing cost on foot, and especially parallel twin axle tailstock 1A is together with the slide 2A of bottom; owing to be pressure-bearing type; carry in the work of whole group lathe, promptly accounting for very big space, so; dislike slightly and do not have an economy practicality; therefore this case creator exhausts thought at above-mentioned disappearance, makes persistent efforts, and develops a kind of structural improvement of the perfect tail stock that more becomes.

The utility model content

The utility model relates to a kind of structural improvement of tail stock, it mainly is that the twin shaft design that the twin axle tailstock is parallel is the twin shaft of upright (vertically), utilize the actuator state of oscilaltion to finish the one-stop operation of boring, tapping, so not only can prevent bump, and more do not take up space, have more economy, safe, practical, for the utility model is mainly emphasized.

The technical scheme that the utility model provides is as follows:

A kind of structural improvement of tail stock, it is that a tail stock is arranged, this tailstock mainly comprises and is provided with upright, a rectilinear axis of cone seat, be provided with four axis holes in the seat, in two axis holes up and down wherein, respectively pass through and put an oil hydraulic cylinder axle and utmost point cover, utmost point piece, in middle two axis holes, respectively pass through again and put boring axle sleeve, a tapping axle sleeve and a drill, tooth attacking device, again with oil hydraulic cylinder axle and boring axle sleeve, tapping axle sleeve end built-in in a piece, wherein; Again should be uprightly, rectilinear axis of cone seat utilizes one side conical surface build-in to be the inner conical surface of L type conical surface slide in another, be provided with an oil hydraulic cylinder axle in the conical surface slide seat and be supported with a long slide plate, utilize a bolt group to be locked on fine setting about outer doing at last, but put in order the group tailstock and be an oscilaltion state with L type conical surface slide, a side of tailstock is combined with a PC control cabinet in addition, and in the upper end of axle bed each side be provided with an oil pressure flow valve and boring before limit switch, back limit switch, again in slide contact with long slide plate a side establish a tailstock after limit switch, limit switch before establishing a tapping in slide bottom with the contact jaw of axle bed in addition, the preceding two side ends of slide bottom are respectively established tapping limit switch after switch and the tapping at a slow speed.

The specific embodiment

See also Fig. 3,4,5, it is exploded perspective schematic diagram of the present utility model, three-dimensional combination schematic diagram, diagrammatic cross-sectional side elevation, the utility model is that a tail stock 1 is arranged, this tailstock mainly comprises and is provided with upright (vertically) formula axis of cone seat 10, be provided with four axis holes 101 in the seat, 102,103,104, in two axis holes 101 up and down wherein, respectively pass through in 102 and put an oil hydraulic cylinder axle 11,12 and utmost point cover 111,121, utmost point piece 112,122, again in middle two axis holes 103, respectively pass through in 104 and put a boring axle sleeve 13, a tapping axle sleeve 14 and a drill 15, tooth attacking device 16, again with oil hydraulic cylinder axle 11,12 and boring axle sleeve 13, tapping axle sleeve 14 end built-ins are in a

piece

17,18, wherein; To be somebody's turn to do upright (vertically) formula axis of cone seat 10 again utilizes the one side conical surface 105 build-ins to be the inner conical surface 20 of L type conical surface slide 2 in another, be provided with an oil hydraulic cylinder axle 21 in 2 of the conical surface slides and be supported with a long slide plate 22, utilize a bolt group 3 to be locked on fine setting about outer doing at last, but put in order group tailstock 1 and be an oscilaltion state with L type conical surface slide 2, a side of tailstock 1 is combined with a PC control cabinet 5 in addition, and in the upper end of axle bed 10 each side be provided with an oil pressure flow valve 51 and boring before limit switch 52, back limit switch 53, again in slide 2 contact with long slide plate 22 side establish a tailstock after limit switch 54, limit switch 55 before establishing a tapping in slide 2 bottoms 23 with the contact jaw of axle bed 10 in addition, the preceding two side ends of slide 2 bottoms 23 is respectively established tapping limit switch 57 after switch 56 and the tapping at a slow speed, so, be the primary clustering of this case creation.

When desire operation boring earlier, during back tapping automatic job, at first open PC control cabinet 5 power supplys, after setting exercises, this moment, 11 meetings of oil hydraulic cylinder axle were toward touching oil pressure flow valve 51 forward, make boring axle sleeve 13 drive the action that drill 15 advances and does boring, when the main desired depth of boring, owing to run into the preceding limit switch 52 of boring, drill 15 is promptly return voluntarily, run into boring back limit switch 53 after returning, main shaft 6 recovers rotating speed, at this moment, whole group tailstock 1 can break away from the bottom 23 of conical surface slide 2 synchronously, do the rising of spacing in inner conical surface 20 by the long slide plate 22 of oil hydraulic cylinder axle 21 supports, (as shown in Figure 6) and brush up against limit switch 54 behind the tailstock, oil hydraulic cylinder axle 12 can make tapping axle sleeve 14 drive tooth attacking devices 16 advance forward at this moment, this moment, main shaft 6 rotating speeds can be slack-off synchronously, when the tooth attacking device 16 that advances during fast near working substance, can brush up against tapping switch 56 at a slow speed, make main shaft 6 run-in synchronisms, when allowing tapping to the degree of depth in advance owing to run into limit switch 55 before the tapping, main shaft 6 synchronous reversions, tooth attacking device 16 is promptly return voluntarily, run into limit switch 57 after the tapping, main shaft promptly recovers original rotating speed voluntarily, and whole group tailstock 1 promptly descends by long slide plate 22 thereupon, so promptly finishes boring, an automatic job of tapping.

The utility model will be emphasized, boring, the tapping

twin shaft cover

13,14 that is tailstock 1 upright (vertically) formula drives drill 15, tooth attacking device 16 is done the lifting of spacing up and down in conical surface slide 2, use and reach boring, automatic job of tapping, so the upright structures design is owing to drill 15, tooth attacking device 16 are adopted lifting up and down when automatic shift, so can never strike left and right knife rest 7 avris, use the safe convenience of promoting operation, and more do not account for the space that lathe work is lifted, can be rated as and have more economic and practical.
