Description

Technical Field

[0001] The present invention relates to the technical field of turning processing of pipe fittings connectors, and particularly to a turning device for processing pipe fittings connectors and a control method thereof. Background Art

[0002] A pipe fittings connector is a device used to connect pipes, pipe fittings, equipment or components, and its function is to ensure that the pipe system has good sealing performance, stability, and smooth fluid flow. There are various types of pipe fittings connectors, and different types of connectors can be selected according to different application requirements, fluid media, working pressures, and temperature requirements. The processing of pipe fittings connectors generally requires precise turning and cutting processes to ensure the sealing performance and firmness of the connector after installation.

[0003] In the field of manufacturing pipe fittings connectors, the turning processing of valve body flange connectors by traditional machine tools mainly relies on a three-jaw chuck to clamp and position the valve body flange end. This conventional clamping method has inherent defects when dealing with eccentric flange ends: when the rotating spindle of the machine tool drives the valve body to rotate at high speed, due to the uneven mass distribution of the eccentric flange end of the valve body, a periodic centrifugal force will be generated. This centrifugal force is transmitted to the machine tool spindle system through the clamping part, causing spindle vibration, and further transmitted to the machine tool guide rail and tool rest. This vibration will not only cause the relative position of the tool and the workpiece to shift, resulting in precision problems such as aperture size deviation and excessive surface roughness, but also accelerate tool wear and shorten its service life. In severe cases, it may even cause tool chipping or damage to the machine tool spindle bearing.

[0004] In summary, in the prior art, there is a lack of technology for providing counterweight for assisting in the turning processing of the eccentric flange end of the valve body. Summary of the Invention

[0026] like Figure 7 As shown, a water injection cavity 801 is provided on the inner wall of the intelligent counterweight seat 8, a piston ring 802 is provided on the inner wall of the water injection cavity 801 in a sliding manner, a drainage pipe 803 is provided through and fixedly connected to the piston ring 802, a flow control valve is installed in the drainage pipe 803, an electric push rod 804 is provided through and fixedly connected to the outer wall of the bottom end of the intelligent counterweight seat 8, and the output end of the electric push rod 804 is fixedly connected to the piston ring 802.

At the same time, the electric push rod 804 is used to drive the piston ring 802 to move, so as to avoid the existence of cavities in the water injection cavity 801.

[0027] By setting up the intelligent counterweight seat 8 and the counterweight limiting mechanism 10, the inside of the intelligent counterweight seat 8 can further add an appropriate amount of water as a counterweight on the basis of the metal counterweight plate 901 as needed, so as to realize flexible adjustment of the counterweight. According to the needs of different processing, the weight of the counterweight can be accurately controlled to ensure the stability and accuracy of the processing process. At the same time, the counterweight limiting mechanism 10 can limit and fix multiple metal counterweight plates 901 on the clamping plate 4. When turning the eccentric flange, the intelligent counterweight adjustment and limit fixing mechanism not only improves the processing accuracy and safety, but also has obvious advantages in reducing costs and improving efficiency.

[0028] like Figure 8 As shown, the outer wall of the limiting shaft 9 is sleeved with a plurality of metal counterweight discs 901, and finger grooves 902 are provided on both sides of the metal counterweight discs 901.

The finger grooves 902 facilitate the removal and placement of the stacked metal counterweight discs 901.

[0029] like Figure 9As shown in the figure, the counterweight limiting mechanism 10 includes a threaded rod 1001. The threaded rod 1001 is rotatably connected to the limiting shaft 9. The bottom end of the threaded rod 1001 extends into the intelligent counterweight seat 8 and is fixedly connected with a motor C 1002. The motor C 1002 is fixedly connected to the inner wall of the intelligent counterweight seat 8. A moving block 1003 is threadedly connected to the outer wall of the threaded rod 1001.

The top end of the contact rod 1007 is in sliding contact with the inner wall of the conical groove 903. By driving the threaded rod 1001 to rotate with the motor C 1002, the threaded rod 1001 drives the moving block 1003 to move downward. At this time, the contact rod 1007 on the limiting block 1006 is not in contact with the inner wall of the conical groove 903. Under the action of the tension spring 1005, the limiting block 1006 connected to the slider 1004 will be moved out. Then, driven by the threaded rod 1001, the limiting block 1006 presses on the metal counterweight plate 901.

[0030] A control method for a turning device in the processing of pipe fittings connectors includes the following steps: S1. When turning an eccentric flange is required, first fix the eccentric flange with the clamping disc 4, and then insert the mounting frame 6 onto the adjusting ring 5 for fixation. S2. Then drive the adjusting ring 5 to rotate so that the mounting frame 6 is located above. Then, under the action of the counterweight limiting mechanism 10, limit and fix the counterweight. S3. Then drive the eccentric flange to rotate for processing with the main shaft 3. At this time, install an acceleration sensor and a vibration sensor on the lathe, and collect the dynamic information of the eccentric flange during the turning process through these sensors, especially the vibration frequency and amplitude generated by the eccentric flange. S4. Based on the data collected by the sensors, use physical models such as the inertial mass distribution model to calculate the weight and position of the counterweight to be added. Based on the real-time data during the turning process, use a machine learning model to continuously adjust the position of the counterweight through the adjusting mechanism 7, and adjust the water volume in the intelligent counterweight seat 8. Through intelligent control, ensure the balance of the eccentric flange during the processing.

[0031] Working principle: When processing an eccentric flange is required, first drive the connected jaws 402 to move with multiple hydraulic cylinders 401 to clamp and fix the eccentric flange. Then insert the insertion rod 601 on the mounting frame 6 into the clamping hole 503. At this time, under the action of the spring 603, the clamping block 602 will be clamped with the clamping hole 503. Then, a certain number of metal counterweight discs 901 are sleeved on the limit shaft 9, and then the motor C 1002 is used to drive the threaded rod 1001 to rotate, so that the threaded rod 1001 drives the moving block 1003 to move downward. At this time, the contact rod 1007 on the limit block 1006 does not contact the inner wall of the conical groove 903, and under the action of the tension spring 1005, it will drive the limit block 1006 connected to the slider 1004 to move out. Then, driven by the threaded rod 1001, the limit block 1006 presses on the metal counterweight disc 901 to limit it; Then, the motor A 403 is used to drive the adjusting wheel 404 to rotate, the adjusting wheel 404 drives the limit ring 501 connected to the annular rack 502 to rotate, and further the limit ring 501 drives the adjusting ring 5 to rotate, so that the intelligent counterweight seat 8 moves to a position symmetric to the eccentric end of the eccentric flange; Then, when the main shaft 3 drives the eccentric flange to rotate for machining, according to the data detected by the sensor, the motor B 702 is used to drive the bidirectional worm 701 to rotate, the bidirectional worm 701 drives the link group 704 connected to the worm wheel 703 to rotate, and further the link group 704 drives the intelligent counterweight seat 8 connected to the adjusting frame 705 to adjust the position. At the same time, during the turning machining of the eccentric flange, as the turning progresses, the weight of the eccentric flange decreases. At this time, according to the detected data, the flow control valve in the drain pipe 803 is opened to quantitatively discharge the water in the water injection cavity 801, and at the same time, the piston ring 802 is driven to move by the electric push rod 804 to prevent an air cavity from appearing in the water injection cavity 801 and ensure the balance of the eccentric flange during the machining process.
