Abstract

This invention relates to a coupling device for clamping jigs, including a base, a coupling base, a cover base, wherein the base is disposed therein with plural jaws for clamping a jig, and the coupling base for driving the jaws to radially move to clamping positions or recede to unclamping positions. Atop of the coupling base is provided with the cover base locked to the base. A top of the coupling base is provided with a slot and a push lever. The slot is provided with an elastically movable return-stopping portion. The slot is provided with a slant corresponding to the return-stopping portion. By using the push lever to drive rotation of the coupling base, the return-stopping portion is activated to rise along the slant causing the return-stopping portion to urge tightly against the base of the cover base, thereby causing the coupling base to guide the claws to move forwards during rotation to clamp the jig, so as to provide a fixed and secured effect capable of preventing reversed rotation of the coupling base that may result in recession of the jaws and non-effective clamping.

The utility model is arranged to be placed on the second groove (342) and pressed by one end of the elastic member (9), and the top surface of the slider 1 is concavely recessed into a U-shaped groove (421), so that the pin-shaped lock member ghost ( 43) Put into the groove (421), so that the two ends of the lock member (43) are placed on the groove (3 cattle, face (351), and when the joint (3〇) is to be manipulated, the push handle Insert the deep groove (33 1 ) so that the push handle (36) - side touches the slider (42). The cover seat (50) is a solid seat for covering the top of the joint (3〇) The surface is joined to the pedestal (20) by bolts, and the upper portion of the element (the upper portion of the anti-reverse portion (40) is prevented from falling off. Thus, the preferred embodiment is constructed. As shown in the first and sixth figures, the elastic member (41) is compressed, and the push handle (36) has not been rotated, and the jaw (25) is located in the fixed slot (311) as shown in the tenth figure. Position, this is the retracted state, has not entered the clamping operation, at this time, the main shaft (12) of the jig (10) can be pierced through the perforation (211) into the hole (332) of the coupling seat (3〇), neck The outer peripheral side of the portion (121) is the jaws (25), and the check (4 0 ) state is as follows. Figure 8; Next, please refer to the fifth, seventh, and ninth diagrams. Turn the push handle (36) toward the locking direction to displace the push handle (36) toward the other side in the deep groove (331). The compressed elastic member (41) is elastically extended to push the slider (42) to move along the second groove (342), so that the slider (42) touches the push handle (36), and the lock member (43) follows. The result of the displacement is guided by the inclined surface (351) to form an upward movement against the bottom surface of the cover seat (5〇), and the lock member (43) is counterclockwise due to the lateral force of the push handle (36). Rotating, so that the bottom surface of the cover seat (50) can be brought into close contact force. According to the seventh and eleventh figures, when the push handle (36) is continuously rotated, the push handle (36) side pushes the deep groove. '(331) the inner side wall, causing the coupling seat (30) to rotate in the locking direction, resulting in a joint country

Page 10 1284579 V. INSTRUCTIONS (7) (30) The rotation process drives the steel ball (251), causing the return rail (322) to rotate and leave the steel ball (251) to form the guide (321) and the steel ball (251) card. In combination, the cool claw (25) is driven radially toward the center. As shown in the first and eleventh figures, the jaw (25) clamps the neck (121) to reach the binding device clamping fixture (1 ( At this time, the push handle (3 6 ) can be extracted to perform the electric discharge machining. During the machining process, the joint seat (3 〇) is attached to the cover seat by the lock member (43) of the check portion (4 〇). (50) The frictional force of the bottom surface additionally increases the friction positioning function, so that the reinforcing joint (30) can withstand the external force and the shadow of the joint (30) is reversed, resulting in the corresponding center of the jaw (25) and toward the path Retracting from position I causes the problem of ineffective clamping; in addition, the present invention utilizes the guide rail (32 丨) and the homing rail (32) to engage the clamping jaws (25) from start to finish, so that the jaws (25) are in the ablated position, The carry is controlled by the action of the joint seat (30), and the action is quick and accurate. When the operation is completed and the fixture (1〇) is to be removed, as shown in the eighth figure. The handle (36) is reinserted into the deep groove (331), and then the push handle (36) is reversely rotated. During the process, the slider (42) is pushed and the elastic member (41) is compressed to urge the lock member ( 43) Move down along the slope (351) and widen the distance from the bottom surface of the cover (5〇), and continue = push the handle (36) to displace the joint (30) and guide the return rail (32 2 ) back. To the fitting: the state of the steel ball (251) is driven, and the jaw (25) is disengaged from the head of the main shaft (12) (1 2 1 ), that is, the disassembly operation is completed. The base shown in Fig. 12 (201) ), in the inner slot (2

SfrrL does not need to form the limiting groove (10) and the protruding piece (21) as shown in the second figure, because the clamping jaw (25) is limited by the guide rail (321) shown in the third figure, which illustrates the base (2 0 1 ). Change pattern. The above embodiments are merely illustrative of the technology of the present invention and its effects.
