て均一な力で締め付けることは極めて作業性に乏しい。[Invention or problem to be solved] However, with such a gripping device, is it necessary to use a tool to handle small parts such as the set screw 5 in order to grip the object 1 to be gripped? In addition, there is a step of arranging the object to be held between the claw portion 7 of the clamp member 3 and the base 2 to apply a clamping force, and a step of tightening the clamp member 3 with the set screw 5.
It is necessary to perform two different operations in succession, including the process of fixing with screws, and there is a possibility that the fixing position may be slightly shifted when fixing with screws. Furthermore, when a plurality of clamp members are arranged in parallel, it is extremely inefficient to tighten them with a uniform force using set screws.

する。[Means for Solving the Problems] A gripping device of the present invention includes a base on which an object to be gripped is placed, a clamp member that clamps the object to be gripped between the base, and a clamping force applied to the clamp member. The clamp member has a main shaft portion movably penetrating the base, and a claw portion that interlocks with the main shaft portion and comes into contact with the upper surface of the object to be grasped. The hole in the base through which the base is penetrated is characterized by being inclined with respect to the clamping force.

態となって無段階に固定されるものである。[Operation] In the gripping device of the present invention, when the clamp member is pushed up to widen the distance between the base and the claw portion of the clamp member, the clamp member moves approximately along the hole in the base or the claw portion and the base When the object to be grasped is placed between them and the push-up force is released, the claws come into contact with the upper surface of the object to be grasped, and by receiving the reaction force, the main shaft section or the base moves along the thickness direction of the base, that is, the direction of the clamping force. It wakes me up like this. Then, the outer circumferential surface of the main shaft portion comes into contact with the inner circumferential edge of the inclined hole, and in this abutting state, the biasing force of the elastic member acts, resulting in a so-called galling state and stepless fixation.
［実施例］

/[Is it?] It is set in relation to the thickness dimension of the connector 20, and when the claw part 16 comes into contact with the connector 20, the large diameter part 17 of the main shaft part 14 or the hole 15 of the base 11 The inner circumferential edge of the hole 15 and the outer circumferential surface of the main shaft portion 14 on both sides of the base 11, and the corner portion of the stepped portion 2I and the inner circumferential surface of the hole 15 are Three locations A-B/C
The dimensional relationship is set such that the clamp member 12 and the base 11 are in contact with each other.
また、クランプ部材１２の爪部１６は、断面か例えば平

の固定手段を用いる必要はなくなるものである。When gripping the connector 20 with the gripping device configured in this way, the clamp member 12 is pushed up to widen the gap between the claw portion 16 and the base 11, and the connector 20 is placed between them, or each Insert pin 28 into the corresponding hole 27 of connector 20. Then, by releasing the push-up force on the clamp member 12, the claw portion 16 is brought into contact with the upper surface of the connector 20, and the elastic member I
3 applies clamping force. In this case, when the clamp member 12 is pushed up, the clamp member 12 is inclined approximately along the hole 15 of the base 11, but when the push-up force is released, the claw portion 16, which has a rectangular cross section, engages the connector 20. Since it comes into contact with the upper surface, the reaction force thereof causes the main shaft portion 14 to be raised parallel to the thickness direction. Then, as shown in Fig. 1, the base 11
Since the elastic member 13 acts in this abutting state, a frictional force with the hole wall is generated, resulting in a so-called staking state. Therefore, those three contact points A
-C, the main shaft portion 14 can be fixed and movement of the main shaft portion 14 can be restricted, and there is no need to use other fixing means such as a set screw as in the conventional example.

Also, whether the inclination angle θ of the hole 15 is large or the frictional force of the hole wall due to reaction force, that is, the effect of galling, is large.
By adopting the stepped structure of the small diameter portion 18 and the small diameter portion 18, the clearance between the hole 15 of the base 11 and the main shaft portion 14 (DI-d
2) is suppressed from increasing.

If there are three contact points in addition to the contact point on the top surface, the clamp member 12 is supported at three points and fixed, so the inner wall of the hole 15 and the main shaft portion 14 of the clamp member 12 must have at least three contact points. Bye. Furthermore, the present invention can be applied to objects to be grasped other than connectors, and the design of the claw portion of the clamp member, etc. can be changed depending on the shape, size, etc. of the object. Further, it is possible to vary the base thickness, the cross-sectional shape and thickness of the hole 15 and the main shaft portion 14 in various ways.
