Abstract
The utility model discloses a milling machine feeding mechanism, and aims to provide a milling machine feeder which has a simple structure, is fast return, has an overload protection mechanism, and is convenient to install, use and adjust. A milling machine feeding mechanism comprises an electric motor and a screw bevel gear; a steel ball safety clutch is connected with a geared sleeve; the geared sleeve is meshed with a gearwheel rolling on a triple gear of a shaft II; two pinions of the triple gear of the shaft II are respectively meshed with right slip duplicate gears of a shaft III; left slip duplicate gears of a spline shaft III can be respectively meshed with the fixed duplicate gears of the shaft II; the slip duplicate gears of the shaft II can be respectively meshed with slip rolling duplicate gears of a shaft I; and the clutch can slip leftwards and rightwards to be combined with the left and right clutches respectively. In the utility model, the feeding mechanism with 8-level feeding and fast returning can be obtained by adopting first-level worm and gear for speed reduction, adopting four pairs of gears for speed change and using four shafts to cooperate with the clutch; and the steel ball safety clutch is arranged at the initial end of a transmission chain, so that an overload protection function can be achieved during feeding and fast returning.
Description
Technical field
The utility model relates to milling machine, drilling and milling machine feed mechanism.
Background technology
The milling machine feed mechanism replaces hand feed, reduces labour intensity, feeding is even, easy to operate and improve work efficiency greatly, is widely used in the Machining Technology field.But existing feed mechanism has three kinds: a kind of is (traditional mechanism) lifting platform built-in type, is widely used in universal milling machines such as XA6132, X62, X52K, its complex structure, manufacturing cost height, and maintenance is inconvenient; The secondth, outer carry formula (electrical shift) on the arm, be usually used in gun turret milling machine etc., but frequent bad carbon brush, plastic gear are perishable, shake during the many and milling of fault; The 3rd is gear graduation, and looking into relevant patent has " multifunction machine ", " mechanical feed device " etc., but number of steps of speeds is few and do not have an overload protection.
The utility model content
The technical problem that the utility model solves provides a kind of gear graduation feed mechanism, is characterized in: simple in structure, reduction manufacturing cost; Feeding and rewind down all are with overload protection arrangement, are convenient to the milling machine feed mechanism of installing, using and keep in repair.
The utility model is achieved through the following technical measures.It comprises that motor, motor are connected with worm screw, worm gear is fastening with cover, and it puts the border and is provided with uniform some steel ball and springs, and the endoporus and the geared sleeve of cover are slidingly matched, the uniform some grooves of geared sleeve are corresponding with above-mentioned steel ball, by the thrust of stage clip steel ball are sunken in the groove of geared sleeve and transmit moment of torsion; Geared sleeve trackslips on the I axle, with the gear wheel engagement of trackslipping at the triple gear of II axle, two little teeth of triple gear respectively with the right slippage duplex tooth engagement of splined shaft III axle, splined shaft III axle left side slippage duplex tooth respectively with the II axle fixedly the duplex tooth mesh; II axle slippage duplex tooth respectively with the trackslip duplex tooth engagement of I axle; Trackslip duplex tooth and interior cover clutch of I axle fixed, and its right-hand member is installed double sided clutch and is connected with I axle spline also that energy left and right sides slippage can combine with left and right sides clutch respectively.
The utility model adopts first-stage worm gear worm screw reduction of speed, the four pairs of gear graduations, only can obtain the mechanical feed mechanism of 8 grades of feedings and rewind down with four road axles and clutch engagement; The utility model is just held at driving-chain the steel-ball type overload-release clutch is set, and overload protective function is all arranged when making feeding and rewind down.
Description of drawings
Fig. 1 is the utility model drive mechanism schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 1, worm screw 1 is direct-connected with motor, worm gear 2 links to each other with steel-ball type overload-release clutch 3, overload-release clutch 3 trackslips with geared sleeve 4, resistance by groove on stage clip, steel ball and the geared sleeve 4 transmits moment of torsion, geared sleeve 4 and the gear wheel engagement of trackslipping, two little teeth of triple gear 6 at the triple gear 6 of II axle 7 respectively with right slippage duplex tooth 8 engagements of splined shaft III axle 9; Splined shaft III axle 9 left slippage duplex teeth 10,11 respectively with fixedly duplex tooth 12 engagement of II axle 7; II axle 7 slippage duplex teeth 14 respectively with I axle 5 on duplex tooth 15,16 engagement of trackslipping; Trackslip duplex tooth 15,16 and interior cover 18 clutches of I axle 5 are fixed, and its right-hand member double sided clutch 17 is connected with I axle 5 splines, and can left and right sides slippage can combine with left and right sides clutch respectively.
The utility model is in order to obtain 8 grades of feedings, can take following mode to operate: motor power is by worm screw 1 worm gear 2 reductions of speed, reach geared sleeve 4 through steel-ball type overload-release clutch 3, the gear wheel engagement of geared sleeve 4 and triple gear 6, stir splined shaft III axle 9 right slippage duplex teeth 8 respectively with two little teeth engagements of triple gear 6; Stir splined shaft III axle 9 left slippage duplex teeth 10,11 respectively with fixedly duplex tooth 12 engagement of II axle 7; Stir II axle 7 slippage duplex teeth 14 respectively with I axle 5 on duplex tooth 15,16 engagement of trackslipping; Stir above-mentioned three duplex slippage teeth respectively and can obtain (2x2x2) 8 grades of speed changes, and then stir I axle 5 double sided clutches 17 and move to left and combine with the tooth of interior cover 18, power reaches the I axle, meshes through gear 19 and gear 20 again through double sided clutch 17, by 8 grades of feeding speed changes of IV axle output.
The utility model is return fast in order to obtain, can take following mode to operate: to stir I axle 5 double sided clutches 17 and move to right and combine with geared sleeve 4 teeth, come directly to reach the I axle, mesh through gear 19 and gear 20 again, return fast by the output of IV axle through double sided clutch 17 to the power of motor worm worm gear.
Steel-ball type clutch of the present utility model is located at the first end of driving-chain, and the power of motor reaches geared sleeve 4 by worm screw 1 worm gear 2, cover 3.The size of its load force is to obtain by stage clip elastic force by the position of adjusting the some screws of steel-ball type overload-release clutch 3 radial equipartitions.
The steel-ball type clutch that the utility model adopted all has overload protective function when making feeding and rewind down, throws off combination automatically during normal duty during overload automatically.
