Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical equipment manufacturing technology, and in particular to a device for detecting the pneumatic pressure of an AC swing head. Background Technology
[0002] Current methods and devices for detecting the pneumatic pressure of AC oscillating heads have many problems. Some traditional detection devices have low accuracy and cannot accurately measure minute pressure changes, making it difficult to meet the needs of high-precision machining. Other devices are complex to operate and require professional personnel for operation and maintenance, increasing the cost and difficulty of use. In addition, most existing devices cannot achieve real-time monitoring and can only perform periodic checks, which cannot detect abnormal pressure in time and can easily lead to machining accidents. Utility Model Content
[0003] The purpose of this invention is to provide a device for detecting the pneumatic pressure of an AC swing head. This invention provides the following technical solution: A device for detecting the pneumatic pressure of an AC swing head includes three vacuum pressure valves, a pressure gauge, a handwheel, an air filter, a switch, a mounting plate, and pneumatic tubing. The three vacuum pressure valves are connected in series by screws and connecting plates to form a pneumatic passage; The pressure gauge is housed inside the protective housing and is installed on one of the vacuum pressure valves by means of threads or snaps, for real-time detection of pneumatic pressure values; The handwheel is located at the bottom of the device and is used to adjust the air pressure by rotating it. The device is equipped with an air filter element at the bottom, which is connected to the pneumatic inlet through a sealed interface for purifying gas; The device is a monolithic structure and is fixed to the mounting plate with screws. One end of the pneumatic pipeline is connected to the pneumatic outlet on the side wall of the vacuum pressure valve, and the other end is connected to the pneumatic connector of the AC swing head. By opening the valve switch and turning the handwheel to control the pressure value, the pneumatic pressure of the AC swing head can be detected.
[0004] The preferred embodiment of the device for detecting the pneumatic pressure of an AC swing head is that the upper surface of the protective shell containing the pressure gauge is provided with a glass panel, which is made of a reinforced material; the overflow port is integrated into the pressure gauge for safe pressure relief, and the pressure is detected by the deformation of the elastic sensitive element.
[0005] In a preferred embodiment of the device for detecting the pneumatic pressure of an AC swing head, the switch of the vacuum pressure valve is located at the top of the device and arranged in the same direction for easy operation.
[0006] The preferred embodiment of the device for detecting the pneumatic pressure of an AC swing head is that the handwheel rotates clockwise to increase the air pressure and rotates counterclockwise to release the air pressure.
[0007] The preferred embodiment of the device for detecting the pneumatic pressure of an AC swing head is that the pneumatic pipeline is made of a material with good sealing performance to prevent air pressure leakage.
[0008] The preferred embodiment of the device for detecting the pneumatic pressure of an AC swing head is that the vacuum pressure valve is made of H-NBR material.
[0009] The operation process of a device for detecting the pneumatic pressure of an AC oscillating head: After the vacuum pressure valve is turned on, the air pressure enters the device after being purified by the air filter element; the handwheel is turned to adjust and change the air pressure value; The pressure gauge monitors the pressure in real time and displays the value via a pointer, allowing operators to adjust the pressure based on the reading. Finally, the air pressure is transmitted to the AC swing head through the pneumatic-hydraulic pipe to achieve closed-loop monitoring.
[0010] The technical solution of this patent is mainly used in the AC oscillating head of machine tools for machining aerospace parts. It can monitor aerodynamic pressure in real time to ensure that the AC oscillating head works in the optimal state, thereby ensuring high-precision machining of aerospace components. When machining complex-shaped parts such as aircraft engine blades, precise aerodynamic pressure control is crucial to ensuring the aerodynamic performance of the blades. Beneficial effects
[0011] This invention employs a high-precision pressure gauge connected in series with a vacuum air-conditioning pressure valve. The pressure gauge directly detects the pressure value through the deformation of its internal elastic sensitive element, which can accurately and in real time reflect the pressure changes in the pneumatic pipeline of the AC swing head. This overcomes the shortcomings of traditional methods, such as low accuracy and large delay, and provides a reliable guarantee for high-precision machining.
[0012] The pressure readings of this device are displayed intuitively on a dial and adjusted via a handwheel. Operators can quickly learn how to use it, significantly reducing operational difficulty and reliance on specialized personnel, thus saving labor costs.
[0013] This utility model device has a compact, I-shaped structure and can be quickly connected via pneumatic piping to form a detection circuit. It eliminates the original complex detection process and greatly improves production and assembly efficiency.
[0014] The valve core is made of H-NBR material, which has high strength, high tear resistance, and excellent wear resistance, ensuring the durability and reliability of the device under long-term and frequent use. The included air filter element purifies the gas and protects the AC swing head and pneumatic components.
[0015] This device enables real-time monitoring and precise adjustment of the AC swing head's air pressure, ensuring its optimal operating condition. This fundamentally avoids processing accuracy issues caused by abnormal pressure, guaranteeing the high quality and consistency of products such as aerospace components, thereby enhancing the company's market competitiveness.
