Abstract
The utility model provides a mechanical driven rotary work table for the positioning of an end tooth disk, which belongs to the field of the mechanical technology. The work table is mainly composed of a rotary disk, a base, the end tooth disk, and an electric mechanism, wherein the rotary disk is meshed with the base by the end tooth disk, and a lifting motor is connected with a lifting driving wheel and a lifting driven wheel by a shaft; a screw rod is combined with a lifting driven gear by a nut, and the upper end of the screw rod is connected with the rotary disk by a bearing; the lower end of the screw rod is connected with the base by a key, and a transposition motor and a reducer are fixedly connected with a transposition driving wheel; a transposition driven wheel is connected with a main shaft by a key, and the main shaft is fixedly connected with the rotary disk. The utility model has the advantages of high positioning precision, good rigidity, good accuracy retentivity, low failure rate and low cost.
Description
Technical field
The utility model relates to a kind of end-toothed disc location rotary table, belongs to field of mechanical technique.
Background technology
Enterprise's rotary table commonly used has end-toothed disc location hydraulic-driven rotary table and NC rotary table two big classes at present.End-toothed disc location hydraulic-driven rotary table, it is representative with the former JB3556-83 of Ministry of Machine-Building Industry standard rotary table, its operation principle is: locate by end-toothed disc between rotary disk and the base, during transposition, hoist cylinder upwards lifts end-toothed disc is separated, and at this moment, the transposition oil cylinder passes through gear---and tooth bar promotes the rotary disk transposition, after transposition put in place, hoist cylinder moved downward and makes end-toothed disc engagement and locking panoramic table.Advantage is: positioning accuracy, positioning and rigid and precision stability are good; Shortcoming is: oil circuit takes place easily leak the fault rate height.NC rotary table, it,, does not need during transposition to lift, so relatively simple for structure owing to there is not end-toothed disc by no gap worm gear---worm screw is realized the workbench transposition with numerical-control motor.But its transposition precision guarantees that by digital control system so very high to the numerical control system requirements, the electric-control system cost is also very high entirely.And, behind the operation certain hour, can influence precision because the transmission system wearing and tearing produce the gap.
The utility model content
Task of the present utility model provides a kind of positioning accuracy height, and positioning and rigid and precision stability are good, the Mechanical Driven rotary table that fault rate is low.
For realizing above-mentioned task, technical solution of the present utility model is as follows: end-toothed disc location Mechanical Driven rotary table, mainly constitute by rotating disk, base, end-toothed disc, motor, rotating disk and base mesh by end-toothed disc, lifting motor is connected with the lifting driven pulley with the lifting driving wheel by axle, combine by nut between leading screw and the lifting driven gear, form screw-nut body, screw-nut body can be ball-screw nut or common feed screw nut.Be connected by bearing between the upper end of leading screw and the rotating disk, be connected by key between the lower end of leading screw and the base, transposition driving wheel and transposition driven pulley are formed transposition transmission wheel set, and it can be Geneva mechanism that the transposition drive is paid, and also can be incomplete gear mechanism.Fixedly connected between position rotaring motor and decelerator and the transposition driving wheel, be connected by key between transposition driven pulley and the main shaft, fixedly connected between main shaft and the rotating disk.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, end-toothed disc location Mechanical Driven rotary table, mainly by rotating disk 1, base 3, end-toothed disc 2, lifting motor 8, position rotaring motor 10 constitutes, rotating disk 1 meshes by end-toothed disc 2 with base 3, lifting motor 8 is by axle 7 and lifting driving wheel 6 and 5 engagements of lifting driven pulley, leading screw 4 and lifting driven gear 5 combine by nut, form screw-nut body, the upper end of leading screw 4 is connected by end face thrust bearing 17 with rotating disk 1, be connected by key 9 between the lower end of leading screw 4 and the base 3, transposition driving wheel 12 and transposition driven pulley 13 are formed transposition transmission wheel set, position rotaring motor 10 is connected by key or screw with transposition driving wheel 12 with decelerator 11, be connected by key 15 between transposition driven pulley 13 and the main shaft 14, main shaft 14 is connected with pin 18 by screw 16 with rotating disk 1.
During the utility model transposition, lifting motor 8 is just changeing, and drives nut forward by axle 7, lifting driven gear 5 and lifting driving gear 6 and rotates, and moves upward thereby promote rotating disk 1 by leading screw 4, and end-toothed disc 2 is separated, and realizes lifting; Lift put in place after, position rotaring motor 10 drives rotating disk 1 transposition by decelerator 11, transposition driving wheel 12, transposition driven pulley 13, main shaft 14; After transposition put in place, lifting motor 8 counter-rotatings made end-toothed disc 2 engagements, and the locking panoramic table, finish a transposition circulation.
The utlity model has following advantage: 1, owing to adopt Endtooth-disc fix, have positioning accuracy The advantage high, that positioning and rigid is good, precision stability is good. 2, owing to there is not hydraulic mechanism, do not leak Oil hidden danger can greatly reduce fault rate, improves reliability. 3, because running part only provides moving Power and irrelevant with precision, thus need not to adopt senior digital control system, with respect to other numerical control rotary worker Make platform, can greatly reduce the control section cost.
