DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a clamping device for a rotary indexing device of the type C. [Prior Art] Japanese Laid-Open Patent Publication No. Hei 10-220425 discloses a rotary housing which is a rotary indexing device having a holding device. The supply is to the lower side of the clamping plate by means of the piston; the lower part of the clamping member is used for the scalloping plate_pressure_the pressure exerted on the cylinder by the X pressure surface of the living base. In other words, it is not enough to say that the coolness of the work can be said to be sufficient. And the holding force is insufficient = the damage of the load clamp applied to the rotating drive target member. 4 The position of the knife X will produce an error, which will lead to the processing accuracy. [Inventive content] In the device, the clamped holding force of the I-turn indexing device can be used to make the wire-to-fiber resistant clamp. The indexed angle (holding force) of the rotating drive component is kept low, and the device is miniaturized. The $ ' = ' can prevent the reduction of the precision of the guard to achieve the processing efficiency.

The annular holding member i which is formed in the upper portion 6 and which is rotatably attached to the casing 3 and which is rotatably provided to the casing 3 is slidably disposed. The effect of the present invention is as follows: s, the clamping mechanism constituted by the lever member 11 on the cymbal is increased by the urging force of the piston member 6 by the two piston members 6 As explained in more detail, as the piston member 6 is in position due to the action of the urging member 7, the lever member is in contact with the piston member 6 first: ° ^ portion 13 ^ body is locked 'because of the above The action of the pushing force is rotated by the center of the ΪΪ二斟^, corresponding to the 'holding of the holding plate 8 and the shell 3 (four) ^ point ^: -11 ratio from the distance of this ===.== Scale force) _ Rotating vines apply f2r!, and the position will not be biased, and it can be centered for the miniaturization of #^度. In other words, in the case of the conventional clamping device, for example, the rotary indexing device for the working machine is a rotary table ίί!Γΐί2', when the rotary driving target member is a circular table, it is insufficient to maintain the machining. Accuracy, it must be avoided that the force in the direction of the table increases as the machining load increases. 】This: When adding, you need to consider setting the workpiece near the center of the workbench. A is added to the circle's torque on the table so that the number can be limited on the table. In contrast, according to the clip of the present invention, the device 2' can hold the circular working chamber with a sufficiently tolerated clamping core even after being cured, and therefore, the force in the rotational direction is liable to change as the processing load increases. The large distance circle 6 200936300 can be changed to the location. It can also be set to improve the processing efficiency of the maintenance project. It can increase the number of workpieces by secret, and can realize the second item of the ocean. There is no device 2 between the U's because of the clamping plate 8 and the above-described lever structure 10, so that the clamping portion 侔 严 壳体 壳体 壳体 壳体 壳体 壳体 壳体 壳体 壳体 壳体 壳体 环状 环状 环状 环状 环状It leverages 11 miscellaneous pressures, and it is contacted and movable.

Thereby, the disk 8 is increased in the axial direction and applied to the recording surface 8 of the holding holding member 1G. The secret is the card _ = fixed to the inner root of its half-finance, and the face is opposite to the face of the holding disk 8 at a slight interval. The pressing force of the holding ring U U is moved in surface contact with the holding plate 8 at the outer edge portion of the m 8 to the holding plate 8 - 2 . As a result, it is possible to make the ridge seam 8 substantially evenly and evenly, and to be able to hold and hold the state. In addition, it is also possible to omit the gripping member; the holding position is partially "and thus the retaining member u clip 200936300 as described above, in the embodiment, in the components constituting the inflammatory holding device 2, The clamping 29 is easy to unitize, and it can be made to be able to assist the cover member 22 by disassembling the mounting screw 22 and clamping the gripper 19 with the housing 3 Example 2 ❹ 杠杆In the same rotary table device 15 as in the first embodiment, 19) the lion has a braided member_子. Embodiment 1 The distance a ^ # 2 in which the fulcrum portion is formed between the point portion 14 and the force point portion 12 is formed as the (four) length from the force point portion 12 to the fulcrum portion 13 design 14 , which can be obtained in the embodiment 3疋In the same rotation as the embodiment ^ ^ ^ ^ ^ i = t) on the / outer peripheral - side fixed in the example =, other components have been unitized, but if you do not consider the extension structure of the disk 8 It is also possible to directly fix the clip member 10 and the housing 3 by using the housing 3 to guide the two members of the piston member 6 to the wire or to pass through the non-solid 22 as shown. The cover is rotated. Embodiment 4 has a plurality of axes as the biasing force on the circumference of the center: the plug member 6 is pressed in the direction). Thereby, the piston member 6 is always reduced by means of the clamping lever 19 (8 clamps 200936300 9 嶋 fine uniform 8 rounding table - Hi 1 for releasing the release mechanism in the holding state, in the piston member 6 and the card, When looking for the H-gong 16 to perform the indexing action, the working fluid is supplied to the Lai Li room 3. ❹ ί ί ί ϊ 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 ( ( ( ( 松开 松开 松开 松开 松开 松开 松开 松开 松开 松开 松开The clamping force to the holding disk 8 is rotated as if it is in the released state, and the circular table 16 (the rotating shaft 5) is in the example of the evening, as the biasing member 7 has the spring The member 3 has a pressure chamber 26 between the hoe 6 and the tank 23, and supplies the work for clamping to the pressure chamber 26 from the fluid flow path 28 formed on the flow hood member 22, not shown. In addition to the holding force of the spring member (compressing the lug) 30, the tightening force can be increased by the fluid pressure (increasing the clamping force). The figure is that the piston member 6 is clamped to the side by the supply of the working fluid. The clamping device for releasing the displacement in the direction uses the clamping rod 19 本 of the present invention. The wire device of the side can also be made often.
