Embodiment
Below against accompanying drawing, by the description to embodiment, to embodiment of the present utility model as involved Mutual alignment and annexation, the effect of each several part and operation principle, manufacture between the shape of each component, construction, each several part Technique and operate with method etc., are described in further detail, to help those skilled in the art to of the present utility model Utility model design, technical scheme have more complete, accurate and deep understanding.
Referring to Figures 1 and 2, static pressure type unit head of the present utility model is main by brill disk 1, main spindle box 2, axle sleeve 3, main shaft 4 And casing 5 is constituted.
Main spindle box 2 is provided with the slip axis hole with the form fit of axle sleeve 3, and axle sleeve 3 is threaded onto in slip axis hole and can led relatively The straight-line displacement of axle box 2.The inner side for sliding axis hole is provided with the spiral oil groove 6 for being filled with hydraulic oil, by the pressure for changing hydraulic oil Power, can control the coupling mechanism force between main spindle box 2 and axle sleeve 3.When oil pressure is reduced, coupling mechanism force is not enough to realize the lock of axle sleeve 3 Tightly, now axle sleeve 3 can be moved with relative main case 2, and when oil pressure is raised to a certain extent, coupling mechanism force is sufficiently large, now Axle sleeve 3 can no longer be moved with relative main case 2, and both realize mutual locking.
In order to ensure the sealing effectiveness of spiral oil groove 6, main spindle box 2 is provided with spiral oil groove in the two ends for sliding axis hole 6 sealed oil sealings 7.Correspondingly, main spindle box 2 is provided with the fuel inlet fitting 8 connected with spiral oil groove 6 in the side wall for sliding axis hole With delivery connection 9, spiral oil groove 6 is connected by fuel inlet fitting 8 and delivery connection 9 with high-pressure oil passage, by controlling hydraulic oil The oil pressure on road, you can the oil pressure of spiral oil groove 6 is adjusted, so as to realize above-mentioned coupling mechanism force regulatory function.
Main shaft 4 is arranged in axle sleeve 3 and rotatable.Main shaft 4 and axle sleeve 3 can not relative displacements, therefore the relative main of axle sleeve 3 During 2 straight-line displacement of case, main shaft 4 can also follow axle sleeve 3 to carry out corresponding displacement.Specifically, main shaft 4 passes through two in axle sleeve 3 The bearing at end is fixed, in the presence of bearing, and main shaft 4 can be rotated relative to axle sleeve 3.
The front end of main shaft 4 is stretched out from axle sleeve 3, provided with the drive gear 11 that can be engaged with the internal gear 10 of brill disk 1.Specifically such as Shown in Fig. 1, the front end that disk 1 is fixed on axle sleeve 3 by dismountable mode is bored, disk 1 is bored provided with disk cover 12 is bored, bores disk cover 12 and pass through Bolt is connected with axle sleeve 3, and the main body for boring disk 1 is further bolted on brill disk cover 12.Disk 1 is bored provided with straight forward The brill extension bar 13 of stretching, bores extension bar 13 and is fixed on by bearing in the brill main body of disk 1, internal gear 10 is set with each brill extension bar On 13, drive gear 11 is engaged with internal gear 10, and drive gear 11 drives internal gear 10 to rotate when main shaft 4 is rotated, so as to enter one Step drives brill extension bar 13 to rotate.
Casing 5 is fixed on casing 5 located at the rear end of axle sleeve 3 and main shaft 4, axle sleeve 3, and main shaft 4 is fixed on case by bearing On body 5.Because axle sleeve 3 and casing 5 are relatively fixed, therefore during 3 relative main 2 straight-line displacement of case of axle sleeve, casing 5 can also be followed Axle sleeve 3 carries out corresponding displacement.Casing 5 is the installation stationary body of the actuating unit of main shaft 4, its provided with can drive shaft 4 rotate Variable-frequency motor 14, when variable-frequency motor 14 is rotated, main shaft 4 can also follow rotation.As preferred embodiment, casing 5 is provided with Gear chamber, the drive shaft of variable-frequency motor 14 and the end of main shaft 4 are respectively protruding into gear chamber, the drive shaft of variable-frequency motor 14 and master The end of axle 4 is separately installed with synchronizing wheel 15 and synchronizing wheel 16, is connected between synchronizing wheel 15 and synchronizing wheel 16 by timing belt 17. Wherein, in order to play the effect of stable main shaft 4, the end of main shaft 4 can be fixed on the side wall of gear chamber by bearing.Work When, variable-frequency motor 14 obtains electric rotation, and synchronizing wheel 15 follows rotation, and power is transferred at synchronizing wheel 16 by timing belt 17, so that Main shaft 4 is driven to rotate.Variable-frequency motor 14 is aligned for convenience, and variable-frequency motor 14 is fixed on casing 5 by motor adjusting pad 18.
Based on said structure, axle sleeve 3 of the present utility model, main shaft 4 and the composition of casing 5 being capable of the displacements of relative main case 2 Overall structure, realize feed motion.In order to control this displacement of overall structure relative main case 2, casing 5 be provided with axle sleeve 3 and The servomotor 20 that the screw mandrel 19 and drive screw 19 that main shaft 4 is arranged in the same direction are rotated, screw mandrel 19 is extended at main spindle box 2, main Axle box 2 is provided with swivel nut in the feed screw nut 21 on screw mandrel 19.In order to more preferably realize that driving of the servomotor 20 to screw mandrel 19 is imitated Really, shaft coupling 22 is typically provided between servomotor 20 and screw mandrel 19., can be with by controlling servomotor 20 to rotate during work Drive screw mandrel 19 to carry out corresponding rotational action, when screw mandrel 19 is rotated in the feed screw nut 21, the casing 5 that screw mandrel 19 is fixed with And the main spindle box 2 that feed screw nut 21 is fixed can produce corresponding displacement.Therefore, concrete application is worked as and needs to enter the position of main shaft 4 During row adjustment, the oil pressure in spiral oil groove 6 need to only be reduced, release the locking relation between main spindle box 2 and axle sleeve 3, then Control servomotor 20 is acted, you can the displacement to main shaft 4 is accurately adjusted.
As shown in Fig. 2 in order that the overall structure movement that constitutes of axle sleeve 3, main shaft 4 and casing 5 is more stablized, casing 5 provided with the guide rod 23 arranged in the same direction with axle sleeve 3 and main shaft 4, and main spindle box 2 is provided with slip cap loaded on the guide pin bushing on guide rod 23. Under the guide effect of guide rod 23 and guide pin bushing, the overall structure that axle sleeve 3, main shaft 4 and casing 5 are constituted can be with relative main case 2 The displacement effect stablized.
In addition, in order to avoid the overall structure relative moving speed that axle sleeve 3, main shaft 4 and casing 5 are constituted is too fast, preventing Main spindle box 2 produces with casing 5 and is installed with the damping buffer arranged in the same direction with axle sleeve 3 and main shaft 4 on collision, main spindle box 2 24, the movable end of damping buffer 24 is compressed on casing 5.When the relative main case 2 of main shaft 4 stretches out forwards, the He of main spindle box 2 The distance between casing 5 shortens, and damping buffer 24 produces reaction force between main spindle box 2 and casing 5, it is to avoid both are too fast It is close, play protection effect.
The utility model is exemplarily described above in conjunction with accompanying drawing, but is not enumerating for exhaustive, it is clear that this reality It is not subject to the restrictions described above, is entered as long as employing method design of the present utility model with technical scheme with new implement The improvement of capable various unsubstantialities, or it is not improved by it is of the present utility model design and technical scheme directly apply to other fields Close, within protection domain of the present utility model.
