Description

Technical Field

[0001] The utility model relates to the technical field of mechanical clamps, in particular to a telescopic rotating mechanical clamp. Background Art

[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. A fixture usually consists of a positioning element, that is, to determine the correct position of the workpiece in the fixture, a clamping device, a tool guiding element, that is, to determine the relative position of the tool and the workpiece or to guide the direction of the tool, an indexing device, even if the workpiece can be processed in several stations in one installation, there are two types: a rotary indexing device and a linear indexing device, connecting elements, and a fixture base.

[0003] When a traditional mechanical fixture clamps a workpiece, if the fixture fails and loses power, the fixture loses its clamping force and cannot clamp the workpiece, the workpiece will fall, causing additional loss of the workpiece and increasing waste of resources. Utility Model Content

[0004] The utility model aims to provide a telescopic rotating mechanical clamp which can prevent from falling.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] The cam is provided with a plurality of movable parts, and the movable part is provided with a plurality of movable parts, and the movable part is provided with a plurality of movable parts.

[0007] It can be seen that when the clamp is in use, because the electric telescopic rod is rotatably connected to the mounting seat, and the mounting seat is equipped with a clamp box, the electric telescopic rod can drive the clamp box to extend and retract, and the clamp box can be rotated and adjusted. Because the clamp box is provided with an air pump that can drive the connecting piece to slide, the air pump pushes the two push plates to move towards each other. Because the connecting piece is connected to the clamp plate, the push plate can drive the clamp plate to move when it moves, and because the clamp plate is equipped with a stop block, the clamp plate and the stop block can clamp the workpiece. When the equipment fails and the power is cut off, the air pump loses the thrust on the push plate, but because the clamp plate is connected to the limit telescopic rod, and the limit telescopic rod sleeve is provided with a spring, the elastic force of the spring can resist the clamp plate, and the two clamp plates continue to clamp the workpiece, avoiding the workpiece from falling directly after the equipment fails and loses power, thereby increasing protection for the workpiece and reducing waste of resources.

[0008] Furthermore, an electromagnetic reversing valve is installed at the output end of the air pump, and both ends of the electromagnetic reversing valve are connected to connecting pipes. A through hole A is opened in the middle of the inner wall of one side of the cylinder, and through holes B are opened on both sides of the inner wall of the other side of the cylinder. The two connecting pipes are connected to through hole A and through hole B respectively.

[0009] Because the electromagnetic reversing valve is connected to two connecting pipes, the electromagnetic reversing valve can control the direction of the airflow. Because the cylinder is provided with a through hole A, and a connecting pipe is connected to the through hole A, the airflow flowing into the cylinder from the through hole A can push the push plate to move to both sides, and the clamp will be opened at this time. Because the cylinder is provided with two through holes B, and another connecting pipe is connected to the two through holes B, when the airflow flows into the cylinder from the through hole B, it can push the two push plates to move inward. At this time, the clamp is in a clamped state, so the opening and closing of the clamp can be controlled by the air pump.

[0010] Furthermore, the driving assembly includes a mounting sleeve installed on the outer surface of the electric telescopic rod, a motor is installed on the outer surface of the mounting sleeve, a gear A is installed on the output end of the motor, a gear B is installed on the outer surface of the mounting seat, and gear A is meshingly connected with gear B.

[0011] When the motor is powered on, it can drive gear A to rotate. Because gear A is meshed with gear B, and gear B is connected to the mounting base, the rotation of gear A can drive the mounting base to rotate, so the fixture box can be driven to rotate, which is convenient for adjusting the angle of the fixture and increasing convenience.

[0012] Furthermore, a protective shell is provided on the outer side of the motor and the gear A, and the protective shell is fixedly connected to the telescopic end of the electric telescopic rod.

[0013] Because a protective shell is provided on the outside of the motor and the gear A, the protective shell can protect the motor and the gear A and increase the service life of the motor and the gear A.

[0014] Furthermore, the opposite surfaces of the two abutting blocks are both provided with arc-shaped surfaces.

[0015] The curved surface can facilitate the movement of the workpiece to the surface of the stop block, increasing the convenience of clamping.

[0016] Furthermore, rubber pads are provided on the opposite surfaces of the two clamping plates.

[0017] The rubber pad can protect the workpiece, prevent the fixture from damaging the workpiece, and increase the production yield of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS
