Description
Technical field
The present invention relates to a kind of horizontal feed device, the horizontal feed device of the NC vertical lathe of especially maximum processing work diameter 2.5m.
Background technology
The horizontal feed device is the critical piece of NC vertical lathe level (X axle) feed system, and it is as power transfer unit, and the gyration of servomotor is passed to ball-screw, realizes the linear motion of straight horizontal of knife rest.In the process to plain edition C5225 product numerical control transformation, we find, they generally adopt the driving-chain of the old-fashioned structure of complicacy, the poor efficiency of feed box-T type leading screw, low precision, and if use decelerator such as ZF; Problems such as existing though performance is very high costs an arm and a leg waits, maintenance difficult at present, urgently in the industry hope to research and develop a kind of new product; Can satisfy instructions for use, can reduce cost again, reduce the maintaining expense; And structure is simpler, and is clear, keeps in repair more convenient.
Though synchronous cog belt is reliable transmission in transmission mechanism; Strong shock resistance, but because the tooth that is compounded on the driving-belt very easily is damaged in the transferring power process, generally be usually used in the drive apparatus of rotary speed precision requirement than higher constant speed or small-power transmission; At present; This kind of drive is used to have than the increasing of large speed ratio, deceleration transmission system, the occasion of concrete big power output simultaneously, for example at reduction of speed than being 1:4; And use in the NC vertical lathe of maximum machining diameter 2.5m, and be not reported.
Summary of the invention
The objective of the invention is to: the above-mentioned a series of problems to feed box-T type leading screw commonly used in the horizontal feed device of the NC vertical lathe of maximum machining diameter 2.5m or ZF decelerator exist provide a kind of new horizontal feed device.
The objective of the invention is to realize like this: the horizontal feed device of the NC vertical lathe of a kind of maximum machining diameter 2.5m; Comprise crossbeam, crossbeam end plate, servomotor and leading screw; The crossbeam end plate is installed on the crossbeam end face, and servomotor and leading screw are installed on the homonymy crossbeam end plate, it is characterized in that: the crossbeam end plate is provided with roll adjustment slide and axle sleeve; Servomotor is fixedly mounted on the crossbeam end plate through the roll adjustment slide; Leading screw is installed in the axle sleeve through bearing, and the profile of tooth driven pulley is fixedly mounted on the end of leading screw, and servomotor and cogged belt wheel are fixedly linked; Reduction of speed between cogged belt wheel and the profile of tooth driven pulley is than being 1:4; Centre-to-centre spacing is 400 ~ 420mm, and the cogged belt wheel passes through the synchronous cog belt synchronization links with the profile of tooth driven pulley, has 7 intermeshing teeth at least in the cornerite zone that forms between synchronous cog belt and the cogged belt wheel.
In the present invention, described bearing is a combination bearing.
In the present invention, described combination bearing outer ring installation sealing ring.
In the present invention; Described servomotor is fixedly mounted on the crossbeam end plate through the roll adjustment slide and is meant: after servomotor and roll adjustment slide are fixing; Earlier through stretching screw adjustment motor shaft and leading screw centre-to-centre spacing, again by lock-screw with the fixed-site of roll adjustment slide on the crossbeam end plate.
In the present invention, on the crossbeam end plate protective cover is installed, described protective cover covers in synchronous cog belt wherein.
The invention has the advantages that: owing to be through the synchronous cog belt synchronization links between the profile of tooth driven pulley of the cogged belt of servomotor wheel and leading screw; This kind of drive is not only simple in structure; Easy to maintenance, noise is little, need not lubricate; Use cost is relatively low; Servomotor is in the cornerite zone that forms between best inertia matching state, especially synchronous cog belt and the cogged belt wheel has 7 intermeshing teeth at least, can make synchronous cog belt have enough bearing capacitys; Owing at the combination bearing place rotary seal ring is installed, can be prevented that lubricating oil from getting in the synchronous cog belt; Because servomotor is fixedly mounted on the crossbeam end plate through the roll adjustment slide, can regulate the spacing of profile of tooth driving pulley and the passive belt wheel of profile of tooth easily, change the tensile force of synchronous cog belt; Leading screw is installed in the axle sleeve through combination bearing, can under the installing space that allows, makes whole leading screw unit have best axial push-pull rigidity, farthest promoted the positioning accuracy and the kinematic accuracy of knife rest.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the sketch map of the kind of drive of the embodiment of the invention
Among the figure: 1, roll adjustment slide, 2, servomotor, 3, the cogged belt wheel, 4, the crossbeam end plate; 5, profile of tooth driven pulley, 6, leading screw, 7, combination bearing, 8, rotary seal ring; 9, axle sleeve, 10, protective cover, 11, crossbeam, 12, screw; 13, synchronous cog belt, 14, lock-screw, 15, stretching screw.
The specific embodiment
Accompanying drawing discloses the concrete structure of the embodiment of the invention without limitation, below in conjunction with accompanying drawing the present invention is done to describe further
By Fig. 1,2 visible, the synchronous belt transmission device that the present invention includes crossbeam 11, crossbeam end plate 4, servomotor 2, forms by cogged belt wheel 3, the passive belt wheel 5 of profile of tooth and synchronous cog belt 13, major parts such as leading screw 6 composition.Described crossbeam end plate 4 is fixed on crossbeam 11 ends through screw 12, and servomotor 2 is installed on the roll adjustment slide 1; After servomotor 2 and roll adjustment slide 1 were fixing, roll adjustment slide 1 was earlier through stretching screw 15 adjustment motor shaft and leading screw centre-to-centre spacing, again by lock-screw 14 with its fixed-site on crossbeam end plate 4; Leading screw 6, combination bearing 7, rotary sealing 8 are fixed on the crossbeam end plate 4 through axle sleeve 9; Profile of tooth driven pulley 5 is connected and installed through key and is fixed on leading screw 6 one ends; Driving pulley 3 is fixed on the motor shaft of servomotor 2; With synchronous cog belt 13 synchronization links, form driving-chain between cogged belt wheel 3 and the profile of tooth driven pulley 5; Protective cover 10 covers in crossbeam end plate 4 and synchronous pulley device wherein fully, reaches dustproof, grease proofing effect.
Because the horizontal feed device at NC vertical lathe is to adopt deceleration transmission; The diameter of cogged belt wheel 3 is less than profile of tooth driven pulley 5; In order to guarantee that synchronous cog belt 13 has enough bearing capacitys in the process of transferring power; In design, must satisfy: when cogged belt wheel 3 passes through synchronous cog belt 13 synchronization links with profile of tooth driven pulley 5; Have 7 intermeshing teeth at least in the cornerite zone that forms between synchronous cog belt 13 and the cogged belt wheel 3, share the power of cogged belt wheel 3 jointly, drive profile of tooth driven pulley 5 then by them.In the present embodiment, the reduction of speed between cogged belt wheel 3 and the profile of tooth driven pulley 5 is than being 1:4, and centre-to-centre spacing is 410mm, in the cornerite zone that forms between synchronous cog belt 13 and the cogged belt wheel 38 intermeshing teeth is arranged.
