Description

TECHNICAL FIELD

[0001] The utility model relates to valve machining technical field, concretely is a kind of quick clamping mechanism for valve machining. BACKGROUND

[0002] In the automatic machining production line, the clamping and fixing of valve and other parts have always been a technical difficulty. The traditional clamping method often uses mechanical clamping or pneumatic clamping, but these methods have limited flexibility and adaptability when dealing with valves of different sizes and shapes. At the same time, the traditional clamping method may cause damage to the valve surface during clamping, affecting the quality and appearance of the product.

[0003] In addition, with the improvement of automation, the requirements for processing efficiency and precision are also increasing. The traditional clamping method may have errors in positioning, moving and clamping, resulting in a decrease in processing precision. At the same time, the operation process of the traditional clamping method is relatively complicated and requires more manual intervention, affecting the processing efficiency.

[0004] Therefore, there is an urgent need in the market for a new type of quick clamping structure that can adapt to valves of different sizes and shapes without causing damage to the valve surface during clamping, while having high precision and high efficiency. The present invention is proposed in this background, which realizes quick, accurate and stable clamping of the valve by combining the longitudinal and horizontal moving screw module, the carrying mechanical arm and the quick clamping structure, improves the processing efficiency and precision, meets the market demand, and provides an alternative or replacement technical solution for the above problems. CONTENT OF THE UTILITY MODEL

[0005] To achieve the above purpose, the utility model realizes the following technical scheme: a quick clamping mechanism for valve machining, comprising: a machining support, a longitudinal and horizontal moving screw module, a carrying mechanical arm and a quick clamping structure, the longitudinal and horizontal moving screw module is installed on the machining support, the carrying mechanical arm is installed on the moving end of the longitudinal and horizontal moving screw module, the quick clamping structure is installed on the carrying mechanical arm, the quick clamping structure comprises: a concave sleeve block, a pair of sleeve T-shaped shaft pipes, a pair of telescopic inner shaft rods, a pair of horizontal telescopic magnets, a pair of horizontal telescopic electromagnets, an electrorheological fluid tank, a multi-channel valve, a liquid pump, a pair of sleeve liquid capsules and a circular-arc extrusion liquid capsule.

[0006] The concave assembly block is mounted on the handling robotic arm. The arc-shaped extrusion bladder is mounted on the inner side of the concave assembly block. A pair of T-shaped shaft tubes are inserted into both sides of the concave assembly block. A pair of liquid bladders are respectively mounted on a pair of T-shaped shaft tubes. A pair of telescopic inner shafts are respectively movably inserted into the inner side of a pair of T-shaped shaft tubes, and the pair of telescopic inner shafts are respectively connected to a pair of liquid bladders. A pair of horizontal telescopic magnets are respectively mounted on a pair of telescopic inner shafts. A pair of horizontal telescopic electromagnets are respectively mounted on a pair of T-shaped shaft tubes. The electrorheological fluid tank is mounted on the concave assembly block. The pump is mounted on the electrorheological fluid tank. The multi-channel valve is mounted on the pump, and the multi-channel valve is connected to the arc-shaped extrusion bladder and the pair of liquid bladders.

[0007] It should be noted that, as described above, the scanning camera on the processing component scans the valve on the transport equipment. The longitudinal and transverse moving screw module on the processing support moves, driving the handling robotic arm on its moving end. This robotic arm then moves the concave mounting block longitudinally and transversely, moving it above the valve material. A pair of T-shaped shaft tubes are aligned with the holes on the valve. The horizontal telescopic electromagnets inside the T-shaped shaft tubes are energized, causing them to magnetically repel a pair of horizontal telescopic magnets. These magnets then drive the telescopic inner shafts, which in turn move horizontally along the inner sides of the T-shaped shaft tubes. The system uses a pump to draw liquid from the inside of the electrorheological fluid tank to a multi-channel valve. The valve then draws the liquid to a pair of T-shaped shaft tubes. Hydraulic pressure is applied to fill the pair of liquid bladders inside the T-shaped shaft tubes, causing them to expand. This expansion compresses the valve from the inside. Power is then applied, hardening the electrorheological fluid inside the bladders, further expanding and securing the valve. When release is needed, the power is cut off, and simultaneously, a pair of horizontal telescopic electromagnets are energized in the opposite direction. These electromagnets then extend and retract horizontally towards the electromagnets, causing the liquid bladders to expand and retract steadily towards the inside of the T-shaped shaft tubes, thus extending the bladders to the inside of the tubes.

[0008] Preferably, the processing support is equipped with a scanning camera.

[0009] Preferably, the processing support is provided with a concave transport platform, and a belt conveyor is provided on the concave transport platform.

[0010] Preferably, the belt conveyor is provided with several arc-shaped support blocks.

[0011] Preferably, an infrared scanner is provided on the concave transport platform.

[0012] Preferably, the belt conveyor is equipped with an emergency stop device. Beneficial effects

[0013] This utility model provides a quick clamping mechanism for valve processing. Compared with existing technologies, this quick clamping mechanism for valve processing offers the following advantages: It precisely positions the valve using a scanning camera on the processing assembly, and utilizes a longitudinal and transverse moving screw module to drive a transport robotic arm for rapid and accurate movement; the concave mounting block design on the transport robotic arm is ingenious, achieving stable valve clamping through the cooperation of the T-shaped shaft tube and the telescopic inner shaft, as well as the magnetic interaction between the horizontal telescopic magnet and the electromagnet; the combination of the electrorheological fluid tank and the multi-channel valve allows the fluid bladder to be quickly filled or drained as needed, and the valve is squeezed internally by hydraulic pressure. When energized, the electrorheological fluid hardens, further enhancing clamping stability; when the valve needs to be released, simply de-energize and reverse the current to the horizontal telescopic electromagnet to quickly retract the fluid bladder. This design not only improves processing efficiency but also ensures clamping accuracy and stability, while also possessing flexibility and ease of operation, representing a significant technological innovation and optimization in automated processing production lines.
