Please also refer to the tool clamping device shown in US Pat. No. 5,662,442. There is also a spring group directly seated on the spindle shaft hole. When the knife is retracted, the spring group is pressed against the main shaft, causing the spindle to be deformed and deformed. The bearing outside the main shaft is damaged by the lack of pressure; in addition, the tool clamping device of U.S. Patent No. 5,662,442, in order to improve the puncture force of the tool, uses a large-diameter spring group, so that the relative increase is also required. The diameter of the large main shaft, when the diameter of the main shaft increases, causes the centrifugal force to increase when the main shaft rotates, and the phenomenon occurs when the main shaft is actuated, which causes the precision of the tool held by the main shaft to be reduced during processing, and the centrifugal force is large. In the case where the main shaft is vibrating high, there is also a disadvantage that the spindle is not operated at a high speed. The reason is that in view of the above-mentioned tool clamping device, the spindle and the bearing are prone to damage, the processing is inaccurate, and the tool change time is long, and many other defects are caused by many years of manufacturing and design experience and knowledge in related fields. With the help of many ingenuity, the tool clamping device has been developed and improved in order to exert its higher practical efficiency.

The pneumatic cylinder is actuated as a main embodiment to input gas from the second passage (46) of the set up seat (42) to push the urging rod (3) forward, and when the urging rod (3) moves forward The ball (41) slides down to the bead seat (33) of the urging rod (3) as the urging rod (3) moves, and at the same time, the yoke (.2) is pushed forward, so that The jaws (21) disposed at the front end of the tie rod (2) are displaced to the barrel clamping section (13), and at this time, the jaws (21) are in an open state to provide a knife holder for pre-supply (6) 098100430 Achievements, please refer to the fourth figure, stop the power source (5) [pneumatic cylinder].. input gas, while the gas system remaining in the group base (42) is set by the base (42 The second passage (46) is completely exhausted through the guide passage (52) of the cutter cylinder (51), and the 'applied rod (3) is reversely pushed by the compressed spring group (30). The urging rod (3) moves backwards and falls on the bead (33) (41) 'The system is gradually slipped out by the bead seat (33), and after sliding to the slanting rod (3) chute (331), it is held by the inclined portion (441) of the bead groove (44), and A radial yaw force is generated, and the urging rod (3) is firmly locked and actuated accordingly, even if the spring group (30) in a compressed state pushes the unidirectional push of the tie rod (2) 0982000685-0 Form No. 1010101 9 pages / total 22 pages 1375605 The force is increased several times, so that the jaws (21) which are set at the front end of the tie rod (2) also increase the clamping force of the knife (6) several times, and the cutter tube (6) ) as a firm clamp [At this time, the protrusion (211) of the jaw (21) forms a firm abutment with the abutment portion (121) of the main shaft (丨) of the jaw action portion (12). Furthermore, S Qingyi refers to the fifth and sixth figures. When the clamp (6) is to be loosened, the power source (5) is reactivated, so that the power source (5) is set by the stand. (42) The first passage (45) receives the high-pressure gas through the guide passage (52) of the cutter cylinder (51), and further pushes the force-applying rod forward. At this time, please refer to the eighth diagram. The force of the high-pressure gas only needs to be slightly larger than the generating force of the spring group (30) itself (it is 18〇0 Newton), and the actuating force rod (3) can be moved forward to position the force applying rod (3). The bead (41) in the chute (331) slides to the bead (3) bead seat (33) with the action of the force applying rod (3), and falls into the bead seat (33). The radial locking force of the inner ball (41) on the force applying rod (3) is eliminated, thereby releasing the clamping force of the spring group (30) against the pulling rod (2) at the beginning of the retracting, So that the pull rod (2) can be conveniently pushed forward under the light force of the pneumatic cylinder (5), and then the jaws (21) assembled at the front end of the pull rod (2) are pushed away from the main shaft (1) The jaw action section (12) so that the protrusion (211) of the jaw (21) Disengaged from the state in which the abutting portion (121) of the jaw action portion (12) interferes with each other, and the 'claw (21) is released from the elastic force of the elastic member (22) at the assembly position. The clamp of the cylinder (6) achieves the effect of retracting the knife, and the power source (5) of the stop power is input with high pressure gas. At this time, the high friction system is completely discharged from the second passage (46). Please refer to another embodiment of the present invention, as shown in the seventh figure, the main shaft (7) is provided with a shaft hole (71), and the shaft hole (71) is formed at the end of the 098100430 jaw action section (72). And the jaw action section (72) is convexly provided with abutment form number A01O1 % 10 f22 I 0982000685-0 1375605 (721), and then the jaw action section (72) is extended to form a tapered shape. The barrel clamping section (73) is further provided with a guide block (74) after the shaft hole (71) is located at the jaw action section (72), and the shaft hole (71) is located behind the guide block (74) and has a bead groove. (75), a bevel (751) is formed at the leading edge of the bead (75), and a cavity (76) is formed in the class after the bead (75), and the rear end of the main shaft (7) and the power source are The main body (77) is assembled (the power source is a pneumatic cylinder or a hydraulic cylinder), and the power source main body (77) is located at a front side and a rear side of the piston disc (94) of the urging rod (9). 78) for supplying high pressure gas and hydraulic oil; the pull rod (8) is disposed in the shaft hole (71) of the main shaft (7), and is provided with a clamping jaw (81) at one end, and is disposed on the clamping jaw ( 81) Elastic parts are provided in the assembly (8 2), and a protrusion (811) is convexly disposed on the outer side of the clamping jaw (81), corresponding to the abutting portion (721) protruding from the clamping action portion (72) of the main shaft (7), and then the pulling rod (8) The front side forms a guide groove (83) for being assembled with the guide block (74), and the pull rod (8) is bored with a hole (84)' and the hole of the hole (84) is provided with a bead hole ( 85) for the ball (86) to be accommodated therein; the force applying rod (9) is disposed in the hole (8 4) of the tie rod (8), and the bead seat is provided on the force applying rod (9) ( 91), for the setting of the ball (86) 'and a beveled portion (911) formed on the leading edge of the bead seat (91), and a step portion (92) for the force applying rod (9) for The spring group (9 3) [the spring group (93) is a disc spring] is sleeved on the urging rod (9), and the two ends of the spring group (93) are respectively disposed on the urging rod (9) The rear part of the class part (g 2 ) and the tie rod (8), and the spring group (93) is accommodated in the groove (76) formed by the main shaft (7), and the rear end of the force applying rod (9) is provided Piston 蛊 (94). According to this design, the overall length of the main shaft (7) can be shortened, and the 098100430 0982000685-0 can reach the convenient spindle (7) to penetrate into the inner hole of the machining part for processing, and no form number is added. 〇0]〇1 Page 11/Total 22 pages 1375605 interference phenomenon. Through the above implementation description, it can be seen that the present invention has several advantages, such as: 1. The invention provides a pull rod in the spindle shaft hole, and a spring group and a force applying rod in the pull rod, so that the spring group is seated on the draw rod And between the force-applying rods, according to this, when the knife is retracted, the compressed spring group does not directly press the top axle against the spindle shaft, thereby causing damage to the outer bearing of the spindle.
