Rotary opening and closing clamping device

Abstract

The invention discloses a rotary opening and closing clamping device, which comprises a fixed base (1) and a rotating base (2) capable of rotating relative to the fixed base (1). The rotating base (2)is connected with a chuck assembly (3) which can rotate along with the rotating base (2) to do annular motion on the fixed base (1). The fixed base (1) is provided with a first driving part (11) anda second driving part (12). When the chuck assembly (3) rotates to be in contact with the first driving part (11), the first driving part (11) enables the chuck assembly (3) to be closed. When the chuck assembly (3) rotates to be in contact with the second driving part (12), the second driving part (12) enables the chuck assembly (3) to be opened. The rotary opening and closing clamping device issimple and compact in structure, capable of achieving accurate intermittent opening and closing, small in occupied space, low in failure rate, high in production efficiency and good in product qualitystability.

Description

【Technical field】 [0001] The invention relates to a rotary opening and closing clamping device. 【Background technique】 [0002] At present, electromagnetic components are widely used in various fields, and it is inevitable to often use electromagnetic components in various types of electronic products. The production process of the electromagnetic component involves winding a coil on the ring structure of the magnetic ring to make a magnetic ring induction coil. However, the winding structure used to wind the magnetic ring induction coil on the market is relatively complicated. The winding structure includes a clamping device for clamping the wire. The clamping device includes a manipulator and a cylinder that drives the manipulator to open and close. The manipulator clamps the wire, and the rotating arm rotates with the manipulator and the cylinder as a whole. Therefore, the opening and closing of the manipulator and the rotation of the entire clamping device need to be dr...

However, the winding structure used to wind the magnetic ring induction coil on the market is relatively complicated. The winding structure includes a clamping device for clamping the wire. The clamping device includes a manipulator and a cylinder that drives the manipulator to open and close. The manipulator clamps the wire, and the rotating arm rotates with the manipulator and the cylinder as a whole. Therefore, the opening and closing of the manipulator and the rotation of the entire clamping device need to be driven by a separate driving force, resulting in a complex structure and a large space for the mechanism. Prone to failure, affecting production efficiency and yield quality
