Problems solved by technology

[0002] With the rapid development of the machinery industry, hexagon nuts are widely used. In many jobs, a large number of screws need to be disassembled. The general method is to clamp the screws with a clip, or use a fixed-size concave wrench, but these methods are all to the holder. The position accuracy puts forward very high requirements, and the size of these clamps is fixed for the operation screw, it is not suitable to use the same clamp to clamp screws of various sizes, so its use has received certain restrictions

Embodiment Construction

[0011] In Fig. 1, Fig. 2 and Fig. 3, the electromagnet shaft 5 is placed in the electromagnet casing 3, and a circular electromagnet is fixed in the electromagnet casing 3, and there are two slidable V-shaped blocks 2 on the V-shaped block support 1 , two ends of the crankshaft 4 are respectively connected with the V-shaped block 2 and the electromagnet shaft 5 through pins 7, and the middle part of the crankshaft 4 is positioned on the bottom plate of the electromagnet housing through the fixed shaft 6.

[0012] When the device is working, the whole claw mechanism can be conveniently fixed at the place where the hexagonal screw needs to be clamped. After the claw is energized, the electromagnet shaft 5 will move in the direction of the axis of the hexagonal screw claw, and the crankshaft 4 will be driven by the pin 7, and the crankshaft 4 will then drive the V-shaped block 2, and the V-shaped block 2 can move toward or oppositely, thereby clamping Or loosen the hex screws. T...

Abstract

The invention is a hexagonal bolt holding paw, which comprises a V-shaped block, a V-shaped block support, an electromagnet shell, an electromagnet iron axle, a bent axle and a fixing axle. The electromagnet axle is arranged in the electromagnet shell, a round electromagnet is fixed in the electromagnet shell, two movable V-shaped blocks are provided on the V-shaped block support, the two ends of the bent axle are connected with the V-shaped block and the electromagnet iron axle by a pin, the middle part of the bent axle is positioned at the bottom board of the electromagnet shell by a fixing axle. The paw structure can be fixed on other structures conveniently. The invention can be used in the automatic clamping of hexagonal bolt, which has advantages of quick and accurate clamping bolt, and is suitable for the bolt of different size and improving working environment and efficiency.

Description

technical field [0001] The invention relates to a hexagonal screw clamping claw, which belongs to the technical field of machine engineering, in particular to a mechanical claw with the function of automatically clamping a hexagonal nut. Background technique [0002] With the rapid development of the machinery industry, hex nuts are widely used. In many jobs, a large number of screws need to be disassembled. The general method is to clamp the screws with a clip, or use a fixed-size concave wrench, but these methods are all to the holder. The position accuracy puts forward very high requirements, and the size of these clamps is fixed for the operation screw, it is not suitable to use the same clamp to clamp screws of various sizes, so its use has been restricted to a certain extent. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a hexagonal screw clamping claw, which can accurately and quickly c...
