To the first piston chamber 11 communicated, provided with one first seal isolation between the bottom and taper space 100 of the first piston chamber 11
Part 3, the top of the chuck inner sleeve 2 has a connecting rod for entering first piston chamber 11 through the first seal isolation part 3 center
21, and the top of connecting rod 21 is connected with the first piston 22 matched with the inwall of first piston chamber 11, the first piston 22 is by institute
It is upper chamber 111 and lower chambers 112 to state 11 points of first piston chamber；
In the top position of first piston chamber 11, the second work is radially offered by the outer wall of the chuck outer body 1
Fill in chamber 12, the closing of the one end open one end of second piston chamber 12；A hollow mold insert 4 is provided with the outer section of second piston chamber 12, in this
The empty inside ecto-entad of mold insert 4 offers in internal thread segment 41 and unthreaded hole section 42, and the hollow mold insert 4 and is equipped with an adjusting rod 5,
The outer end outer wall of the adjusting rod 5 has external screw thread 51 corresponding with the internal thread segment 41 of hollow mold insert 4, and the inner of adjusting rod 5 leads to
Unthreaded hole section 42 is crossed to penetrate inside second piston chamber 12, and the inner middle part of adjusting rod 5 is provided with second piston 52, the second piston
52 will be divided into exocoel 121 and inner cavity chamber 122 inside second piston chamber 12, close provided with second at the inner face of hollow mold insert 4
Off member 6 is insulated, the second seal isolation part 6 makes second piston for the sealing of the hollow inwall of mold insert 4 and outer wall and the outer wall of adjusting rod 5
Chamber 12 is sealed off with outside；
The company of offering on distance piece inside chuck outer body 1, between first piston chamber 11 and second piston chamber 12
Lead to the first passage 101 of the upper chamber 111 of the first piston chamber 11 and the exocoel 121 of second piston chamber 12；Outside chuck
Cover in the inside of main body 1, the side wall of first piston chamber 11 and offer the lower chambers 112 and second for connecting the first piston chamber 11
The second channel 102 of the inner cavity chamber 122 of plunger shaft 12.
The outer end of the adjusting rod 5 is provided with interior hexagonal recess 53, i.e. the entirety of adjusting rod 5 can be located at chuck outer body
Inside 1, it is not necessary to exposed, it is adjusted by inner hexagon spanner, keeps overall appearance complete machine attractive in appearance.
The first jump-ring slot 13 is offered at the inside of chuck outer body 1, the first seal isolation part 3 lower surface and is installed
There is the first jump ring 14.During assembling, the connecting rod 21 of the upper end of chuck inner sleeve 2 is first penetrated into the first seal isolation part 3, first is reconnected
Piston 22, then the first jump ring 14 is placed in the lower section of the first seal isolation part 3, it is then that chuck inner sleeve 2 is overall from taper space
100 are pushed upwards, are expanded automatically when the first jump ring 14 is moved at the first jump-ring slot 13, and the first seal isolation part 3 is realized
Positioning assembling, makes square into first piston chamber 11 thereon.
Provided with the second jump-ring slot 15 and the card of installation second at the outer end of second piston chamber 12, the outer end wall of hollow mold insert 4
Second seal isolation part 6 of spring 16, i.e., hollow mold insert 4 and inside is by the second jump ring 16 come location and installation.In the present embodiment,
Second piston 52 is installed also by jump ring and sealing gasket.
Hydraulic oil is filled with first piston chamber 11, second piston chamber 12, is changed using the rotary motion of adjusting rod 5 is driven
Into its linear motion, second piston 52 is driven to inside and outside movement, as illustrated, outwards i.e. second piston 52 is outside when adjusting rod 5
During motion, the space of its exocoel 121 diminishes, and the space of inner cavity chamber 122 becomes big, on the one hand, the oil in exocoel 121 passes through first
In upper chamber 111 below the press-in of passage 101, the oil of upper chamber 111 increases, oil pressure becomes big, and driving first piston 22 is moved downward,
And then chuck inner sleeve 2 is moved downward relative to chuck outer body 1, realize the process for unclamping chuck；Meanwhile, and first piston
The space of lower chambers 112 of chamber 11 diminishes, and oil enters the inner cavity chamber 122 of top by second channel 102；
Conversely, when adjusting rod 5 inwardly i.e. inwardly move by second piston 52, the space of inner cavity chamber 122 diminishes, exocoel 121
Space becomes big, and the oil in inner cavity chamber 122 presses downward to the lower chambers 112 of first piston chamber 11 by second channel 102, makes cavity of resorption
The oil pressure rise of room 112, promotes first piston 22 to move upwards, that is, drives the overall motion upwards of chuck inner sleeve 2, realize the folder of chuck
Tight action；Meanwhile, oil is entered by first passage 101 in the exocoel 121 of top in the upper chamber 111 of first piston chamber 11.
Therefore, no matter adjusting rod 5 is inwardly adjusted or to investigation mission outside the city or town, and the oily flow direction in four chambers is all the unified inverse time
Pin direction or unified clockwise direction, they form the effect mutually promoted, therefore it is very laborsaving during the regulation of adjusting rod 5 and
It is convenient, the agility and accuracy of regulation can be improved.
The utility model is led in four chambers of chuck outer body internal build, two pistons, two by said structure
Road, using hydraulic oil, by driving the motion of one of piston to change the size of two chambers and the motion of hydraulic oil,
And then change size and the oil pressure change of another pair chamber, finally drive the motion of another piston and to complete chuck inner sleeve relative
In the motion of chuck outer body, the clamping or release of chuck are realized, whole regulation process is very laborsaving light, reduction operation
Difficulty, improves the degree of accuracy and the efficiency of regulation.
