Description
Under technical field: the utility model belongs to special boring mill, particularly about the special boring mill of various cylinder body main bearing shells of a kind of boring and cam bearing shell.
Background technology: known main bearing shell and cam bearing shell special boring mill add tower belt pulley as power source with double-speed motor, additional motor elevating mechanism, speed change difficulty, poor stability; Existing equipment is repaiied the big-block engine cylinder body when the main spindle box remote stomidium need be adjusted between cutter and the hole position in boring, because of operator wheel distance, realizes relatively difficulty of boring bar axial feed; In addition, former bushing support is realized elevating movement by worm and gear, rack-and-pinion, because the lifting of two supports separates, during adjustment, takes a lot of work and is difficult for centering; The primitive axis axial feed is realized by the differential screw pair, the main spindle box complex structure, and part is many, Installation and Debugging are difficult, axis feeding moves and rotatablely moves and is associated state, must just can separate rotatablely moving when adjusting cutter through fork, during operation, easily make mistakes with the hole axial dimension.
The purpose of this utility model is: design a kind of bearing shell maintenance special boring mill, its speed governing convenience, compact conformation, simple, processing cylinder body bent axle watt and cam bearing shell precision height.
The technical solution of the utility model: design a kind of bearing shell maintenance special boring mill, it comprises gear, main spindle box, spindle carrier, supporting mechanism, feed mechanism, lathe bed composition, it is characterized in that: gear is a mechanical stepless transmission, it is in transmission connection by driving belt and main spindle box, main spindle box is fixed on the support, supporting mechanism is fixed on the lathe bed, and feed mechanism is that the electronics feeder is fixed on the main spindle box and with spindle drive and is connected.
Described mechanical stepless transmission can be the planetary conical disc type reductor.
Described supporting mechanism is a bushing support elevating mechanism, and its boring bar is connected on two bushings, and two bushings are connected with same leading screw by shift fork respectively.
Described bushing support elevating mechanism, it is by hand wheel shaft, and fork, gear-box, bevel gear pair, base, sleeve, leading screw connect and compose; Feather key is arranged on the hand wheel shaft, and feather key is connected on the gear, and bevel gear pair can move axially along gear shaft 25 in casing, and sleeve 32 can move up and down by leading screw in the base endoporus.
Characteristics of the present utility model are: the utility model is the special boring mill of cylinder body main bearing shell and cam bearing shell, and it is made up of the stepless reductor of planetary conical disc type, lathe bed, main spindle box, electronics feeder, bushing, bushing bracket institution, boring bar, supplemental support, main spindle box support.Its planetary conical disc type reductor directly provides 200---various rotating speeds between the 1000r/min; Its electronics feeder is realized the various axial feed velocities of main shaft by rack-and-pinion, and is provided with mobile switch enclosure, so that remote-controlled operation can realize that by the circuit parallel connection main axis rotation and axial feed are synchronized with the movement; Because screw pair can realize elevating movement, and stirs bevel gear by fork, can make two bushing supports realize elevating movement respectively or simultaneously.So this bearing shell maintenance special boring mill, its speed governing convenience, compact conformation, simple, processing cylinder body bent axle watt and cam bearing shell precision height.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Accompanying drawing 2 is embodiment planetary bevel-type reductor structural representations.
Accompanying drawing 3 is feed mechanism schematic diagrames.
Accompanying drawing 5 is bushing supporting structure schematic diagrames.
Accompanying drawing 6 is accompanying drawing 5 side views.
Accompanying drawing 7 is A-A cutaway views of accompanying drawing 5.
The embodiment explanation: as shown in the figure, star awl disc decelerator 1 is installed on the main spindle box 2, gives sleeve 17 by belt pulley 10,18 and belt 11 with transmission of power, sleeve is used key connecting with axle 16, pass to axle thereby will rotatablely move, axle connects with boring bar 5 by joint 3, realizes the boring campaign.Electronics feeder 20 is connected with main spindle box 2 by connecting plate 21, subsidiary bevel gear of electronics feeder itself and bevel gear 19 are passed to axle 22 with power, again by gear 23, gear sleeve 24 is realized the gear sleeve axially-movable, and gear sleeve 24 is by locking nut 14, bearing cap 15, bearing 13 is realized the axially-movable of output shaft 12, realizes the axial feed of boring bar again by joint 3, switch enclosure 7.Two bushing supports 4 are installed on the lathe bed 6.Handwheel 26 is passed to leading screw 33 by axle 25 rotatablely moving of transmission by gear 28,29, leading screw is by nut 34, sleeve 32, realize the elevating movement of bushing, shift fork 30, pole 31 and gear-box 27 connect, and can realize the difference or the elevating movement simultaneously of two bushings 8, supplemental support 9 is placed tailstock, plays a supportive role when extracting boring bar 5.
When installing and using: the cylinder body with boring cylinder body bearing shell is placed on the parallels of lathe bed earlier, makes cylinder body two ends bearing shell axially bored line and machine tool chief axis line almost coaxial.Adjust two bushing support heights, make bushing common axis and cylinder body bush seat hole common axis basically identical, take off bushing then, it is benchmark with the bush seat hole that boring bar is penetrated in the cylinder body bush seat hole with thick centered cover, make boring bar and seat hole centering, use the tool setting of tool setting scale again.Select the speed of mainshaft and the amount of feeding, connect main shaft and boring bar, try boring, with internal diameter scale actual measurement examination boring bearing shell internal diameter, if formal boring is carried out in tool setting examination boring once more when exceeding watt hole tolerance when satisfying tolerance with joint.The bearing shell hole of finishing boring is detected, meet specification requirement after, take off bushing, boring bar earlier, the cylinder body of finishing processing is carried off, whole bearing shell boring is finished.
