Description

Technical Field

[0001] This utility model relates to the field of oil cavity device technology, and in particular to an intelligent oil cavity device for machine tool turntable with real-time pressure monitoring function. Background Technology

[0002] During the operation of a machine tool rotary table, the oil chamber, as a key component, plays an important role in lubrication, cooling, and support. Traditional machine tool rotary table oil chambers typically employ a fixed volume design, with lubricating oil replenished and drained manually or through simple mechanical devices, lacking real-time monitoring and intelligent control of the internal pressure of the oil chamber. This design presents several challenges: High-precision machining requirements: Machine tool rotary tables need to maintain stable motion accuracy during high-precision machining, and pressure fluctuations in the oil chamber directly affect the stability and repeatability of the rotary table. High load and high-speed operation: Under high load or high-speed operation conditions, the friction and heat of the rotary table increase significantly. The oil chamber needs to provide stable lubrication and cooling to prevent overheating or damage due to abnormal oil pressure. Machine tool equipment requires a higher level of intelligence; traditional manual maintenance and simple mechanical control of the oil chamber can no longer meet the needs of modern manufacturing. Remote monitoring and predictive maintenance: Modern machine tool rotary tables typically require remote monitoring and predictive maintenance. Traditional oil chambers lack data acquisition and communication functions, making it impossible to interact with host computers or remote terminals, limiting the intelligent management of the equipment. Data analysis and optimization: Traditional oil chambers cannot provide historical records and analysis functions for oil pressure data, making it difficult to optimize lubrication parameters and maintenance strategies through data-driven approaches, thus preventing the equipment from fully realizing its potential.

[0003] Traditional machine tool rotary table oil chambers suffer from a lack of pressure monitoring and limited functionality, making it impossible to obtain real-time oil chamber pressure data. This results in uncontrollable lubrication conditions and is prone to friction, wear, or leakage due to abnormal pressure. Traditional oil chambers only have basic lubrication functions and lack intelligent designs such as clamping and remote communication, making it difficult to meet the high precision and automation requirements of modern manufacturing. Therefore, we propose an intelligent oil chamber device for machine tool rotary tables with real-time pressure monitoring to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent oil chamber device for machine tool rotary tables with real-time pressure monitoring function, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A machine tool rotary table intelligent oil chamber device with real-time pressure monitoring function includes: a fixed base, two support blocks fixedly installed on the top of the fixed base, a common oil chamber body rotatably installed between the two support blocks, two mounting holes on the oil chamber body, an oil inlet fixedly installed in one mounting hole and an oil outlet fixedly installed in the other mounting hole, an overflow valve fixedly installed on the oil chamber body, a pressure sensor fixedly installed inside the oil chamber body, a data processing module fixedly installed inside the pressure sensor, a data acquisition module fixedly installed on the top of the pressure sensor, a signal transmission module fixedly installed on one side of the pressure sensor, a motor fixedly installed on the top of the oil chamber body, a limiting frame fixedly installed at the output end of the motor, and a clamping component provided inside the limiting frame.

[0007] Preferably, the clamping assembly includes: a rotating disk and a turbine, both of which are rotatably mounted within a limiting frame. The turbine is fixedly mounted at the bottom of the rotating disk. The rotating disk has multiple arc-shaped holes. Multiple T-shaped slides are slidably mounted within the limiting frame. A clamping block is fixedly mounted on one side of each T-shaped slide. A round rod is fixedly mounted at the bottom of the clamping block, and the round rod is slidably mounted within the arc-shaped holes.

[0008] Preferably, a second motor is fixedly installed inside the limiting frame, a worm gear is fixedly installed on one side of the second motor, the worm gear meshes with a turbine, a rotation groove matching the limiting frame is opened inside the limiting frame, a rotation groove matching the worm gear is opened inside the limiting frame, and a mounting groove matching the second motor is opened inside the limiting frame.

[0009] Preferably, a controller is fixedly installed on one side of the fixed base, a display screen is fixedly installed on one side of the controller, a wireless communication module and an alarm are fixedly installed on the top of the controller, a signal transceiver element is fixedly installed inside the controller, the signal transceiver element is electrically connected to the wireless communication module, and the alarm is electrically connected to the signal transceiver element.

[0010] Preferably, a round rod is fixedly installed on one side of the oil chamber body, one of the support blocks has a rotating groove that matches the round rod, and the other support block has a connecting groove. A motor is fixedly installed in the connecting groove, and the output end of the motor is fixedly connected to the oil chamber body.

[0011] Preferably, the controller has a fixed square groove, in which a storage battery is fixedly installed, and the overflow valve has a sliding groove that matches the T-shaped sliding plate.

[0012] In this utility model, a machine tool rotary table intelligent oil chamber device with real-time pressure monitoring function monitors hydraulic oil pressure in real time through a pressure sensor inside the oil chamber body. The data acquisition module converts the analog signal into a digital signal, and the data processing module filters and calibrates the pressure value to eliminate hydraulic fluctuation interference and ensure data accuracy. The processed data is sent to the signal transceiver element of the controller through the signal transmission module. The controller compares the real-time pressure value with a preset safety threshold. If the pressure exceeds the limit, an alarm is triggered to issue an audible and visual alarm and a warning message is sent to a remote terminal through the wireless communication module. At the same time, the controller automatically releases pressure through the overflow valve to prevent the oil chamber from being overloaded and damaged. The display screen shows the pressure curve and key parameters in real time. All data is stored in the controller's built-in memory, which supports the retrieval and analysis of historical data. The starting motor drives the oil chamber body to rotate around the circular rod in the rotating groove to achieve angle adjustment.

[0013] In this utility model, a machine tool turntable intelligent oil chamber device with real-time pressure monitoring function ensures rotational accuracy through a motor 1 connected in the slot via gear transmission or direct coupling. After angle adjustment, the controller shuts off motor 1 to prevent the oil chamber body from shifting due to inertia or external force. The workpiece is placed at the center of the turntable. The controller starts motor 2, which drives the worm gear to rotate, causing the meshing turbine and the turntable to rotate synchronously. The arc-shaped hole on the turntable pushes the round rod to move outward, and the T-shaped slide slides radially along the sliding groove of the limiting frame, causing multiple clamping blocks to converge towards the center synchronously and clamp the workpiece. The clamping force is indirectly monitored by a pressure sensor to ensure that the clamping force is within a safe range. Motor 2 is started in the reverse direction, and the turbine drives the turntable to rotate in reverse. The arc-shaped hole drives the clamping blocks to expand outward and release the workpiece. The battery provides backup power for the controller, sensor, and wireless module to ensure that data is not lost and the early warning function continues to operate when power is lost. The external power supply prioritizes powering the device and automatically charges the battery.

[0014] This utility model has a reasonable structural design. Through pressure sensors and intelligent algorithms, it can realize real-time monitoring and automatic adjustment of oil chamber pressure, avoiding problems such as poor lubrication or leakage. The clamping component can fix the workpiece, improve lubrication efficiency, reduce manual intervention, integrate a wireless communication module, support remote data transmission and parameter setting, and realize predictive maintenance by combining historical data analysis.
