Definitions
- the present invention relates to a clamp device comprising a fixed clamping member, a movable clamping member and a threaded rod, rotatable, arranged to move the movable member relative to the fixed member.
- Such devices are intended to be used in particular by a carpenter, a carpenter, a cabinet maker, a tinsmith, a decorator, a model maker and any other professional or amateur faced with the problem of maintaining or assembling two objects.
- the invention aims to provide a simple and effective clamp device which can be used without difficulty by a single person to simultaneously carry out the three operations mentioned above.
- the clamp device is characterized in that it comprises means for connecting said threaded rod to a rotary drive device with an electric motor which can be held and controlled with one hand, and means for preventing rotation of the clamping members relative to said drive device.
- the device comprises a rigid frame comprising a guide rod, a fixed clamping arm and a guide arm, these arms being oriented essentially perpendicular to the guide rod, a movable clamping arm forming at one of its ends a sliding ring and having a threaded hole, the threaded rod being guided parallel to the guide rod, free to rotate, at a first end thereof in said fixed clamping arm, and in the vicinity of its second end, in said guide arm and being coupled to said movable clamping arm passing through said hole tapped, this threaded rod being provided, at its second end, with a nozzle for its connection to said rotary drive means, the arrangement being such that said movable clamping arm is made to slide along said guide rod of the armature under the effect of a rotary drive of said threaded rod, an anti-rotation rod integral with the armature being arranged to cooperate with a stop member fixed to said rotary drive means.
- the rotary drive device is preferably an electric screwdriver or drill.
- the device shown in FIG. 1 comprises a rigid frame, for example made of metal, comprising a guide rod 1, a fixed clamping arm 2 and a guide arm 3, these arms being arranged essentially perpendicular to the guide rod.
- a movable clamping arm 4 can slide on the guide rod by means of a sliding ring 5 formed at one of its ends and a tapped hole 6 is formed in an intermediate part of this arm.
- a threaded actuating rod 7 is inserted at one of its ends into a housing 14 of the arm 2 in which it can rotate freely, and it is guided in the vicinity of its other end, being able to also rotate freely in a housing 15 of the arm guide 3.
- the rod 7 passes through the hole 6 of the movable arm 4 and a nut 16 is fixed on this rod in the vicinity of the housing 15, so as to retain the rod in its axial position.
- the end 18 of the threaded rod is provided with a nozzle 17, for example with a hexagon.
- This nozzle is arranged to allow the coupling of the rod 7 with a screwdriver or drill, electric or pneumatic, 10.
- a hollow socket is preferably used with a hexagon as an intermediate piece between the end piece 17, which is introduced into the socket, and this mandrel. This solution also has the advantage of allowing the use of the drill equipped with the hollow socket for actuating several clamping devices of the present type without readjusting the mandrel.
- FIG. 1 a rod 8 is fixed to the rigid frame parallel to the guide rod 1, so as to cooperate with a retaining ring 9 fixed on the drill or screwdriver 10.
- FIG. 2 which represents the ring 9 in top view, shows that the latter comprises a fork-shaped part 11, through which the rod 8 will pass according to FIG. 1, thus preventing rotation of the rigid reinforcement relative to the drive device 10.
- the rod 7 For a drive device with right rotation, the rod 7 carries a left thread and the hole 6 has a thread also on the left. Under these conditions, when the end piece 17 is fixed in the mandrel 19 and the motor of the device 10 is engaged, the clamping arm 4 is moved upwards by the rod 7, sliding by its part 5 along the guide rod 1, for achieve the desired tightening. It should be noted that the end piece 17 can incidentally be actuated manually, for example by means of a key.
- the present device preferably comprises removable clamping heads which can be fixed on the clamping arms 2 and 4.
- Figures 3A, 3B and 3C show an upper clamping head 20 and Figures 4A and 4B a lower clamping head 21 for objects having planar surfaces.
- Figures 5A, 5B and 5C show an upper clamping head 22 and Figures 6A, 6B and 6C a lower clamping head 23 for objects with cylindrical surfaces, for example for pipes.
- the upper clamping heads can be fixed to the arm 2 by means of a clamping pad, as shown in the drawing, and the lower clamping heads can be screwed to the end 12 of the movable clamping arm.
- the clamp device according to the invention makes it easy, by holding the motor drive device in one hand, to put in place and actuate the clamp, the other hand being free to hold the parts to be assembled until tightening is achieved.
