Detailed description of the invention
Describe the present invention below with reference to detailed description of the invention shown in the drawings.But these embodiments are also
It is not intended to the present invention, structure that those of ordinary skill in the art is made, method or functionally according to these embodiments
Conversion is all contained in protection scope of the present invention.
Ginseng Fig. 1, Fig. 2 shown in, in first embodiment of the invention oild chuck include chuck 1, centered by chuck 1 isogonism
Degree extend outward the base 3 of some tooth plates 2, fixed tooth plate 2 and chuck 1, the fluid pressure drive device being located on chuck 1, set
Some claws 4 on tooth plate 2 and the actuating device being connected with fluid pressure drive device and driving tooth plate 2 to move, below to liquid
The structure and working principle of each parts of pressure chuck elaborates.
It is six that tooth plate 2 in present embodiment is correspondingly arranged with corresponding claw 4, and six tooth plates 2 the most uniformly divide
Being distributed in chuck 1 around, on each tooth plate 2, correspondence is provided with a claw 4, and the angle between the adjacent tooth plate of each two 2 is
60°.Certainly, tooth plate 2 and the claw 4 of other quantity can also be set in other embodiments, however it is not limited to present embodiment
In six, the most one by one citing illustrate.
Arranging in hollow in the middle of chuck 1, fluid pressure drive device is installed on the hollow space of chuck 1, specifically, hydraulic-driven
Device includes being positioned at the oil cylinder 51 of chuck 1 central bottom and being positioned at the piston 52 on oil cylinder top, drives piston by oil cylinder 51
52 move up and down at the hollow space of chuck 1, and by actuating device, the up and down motion of piston are converted into tooth plate 2 and claw 4
Axially-movable.
In present embodiment actuating device include the guiding trestle 61 being connected with piston 52 and is connected guiding trestle 61 and
The lever boosting mechanism 62 of tooth plate 2, guiding trestle 61 is connected for the up and down motion of piston 52 is changed into level with piston 52
Axially-movable, and by lever boosting mechanism 62, driving force is amplified, to control tooth plate 2 and the axially-movable of claw 4.
Tooth plate 2 upper surface in present embodiment is evenly distributed with some first teeth groove 201, the cross section of the first teeth groove 201
The rectangle equally arranged, accordingly, the lower surface of claw 4 is correspondingly provided with the second teeth groove being meshed with the first teeth groove 201
The shape complementarity of (not shown), the shape of the second teeth groove and the first teeth groove 201, the rectangle that its cross section the most equally arranges is logical
Cross the engagement of the first teeth groove and the second teeth groove to be fixedly installed on tooth plate 2 by claw 4.
Claw 4 includes the master jaw 41 being fixedly installed on tooth plate 2 and the first card being fixedly installed on master jaw 41
Pawl 42 and the second claw 43, the first claw 42 is positioned at one end of neighbouring chuck 1, and the second claw 43 is located remotely from one end of chuck 1.
In present embodiment oild chuck operation principle particularly as follows:
When oil cylinder 51 drives piston 52 to move upward, guiding trestle 61 and lever boosting mechanism 62 drive tooth plate 2 along
The axis of chuck is protruding, and the second jaw 43 props up workpiece inner ring；
When oil cylinder 51 drives piston 52 to move downward, guiding trestle 61 and lever boosting mechanism 62 drive tooth plate 2 along
The axis of chuck is to contract, and the first jaw 42 clamps workpiece outer ring.
The chucking power of six claws 4 is identical and the self-centering that is synchronized with the movement, and work piece hoisting is put to the rear avoiding the need for and manually adjusted
Whole center, can clamp workpiece by six pawl hydraulic self-centerings.
Present embodiment can change the first jaw 42 or the second jaw by the hydraulic fluid pressure of regulation input oil cylinder 51
The size of 43 chucking powers, particularly as follows:
When oil cylinder 51 drives piston 52 to move upward, the power output of oil cylinder 51 is:
FTop=PA=P* (D/2)2；
Wherein, P is the hydraulic fluid pressure of oil cylinder, and A is effective compression area, and D is cylinder diameter；
Now the chucking power of the second jaw 43 is:
FFolder=FTop(L1/L2)*h；
Wherein, L1、L2Being respectively two brachiums in lever boosting mechanism, h is transmission efficiency.
When oil cylinder 51 drives piston 52 to move downward, the power output of oil cylinder 51 is:
FDraw=PA=P* ((D/2)2-(d/2)2)；
Wherein, P is the hydraulic fluid pressure of oil cylinder, and A is effective compression area, and D is cylinder diameter, and d is the piston in piston
Shank diameter；
Now the chucking power of the first jaw 42 is:
FFolder=FDraw(L1/L2)*h；
Wherein, L1、L2Being respectively two brachiums in lever boosting mechanism, h is transmission efficiency.
