Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-6 The present invention provides a technical solution: an intelligent combined processing equipment and processing method for air pipe connectors, including a machine tool 1, a hydraulic control system and a power supply module.

[0021] The upper end of the machine tool 1 is equipped with a slide rail 2, a drag chain 3 and several support seats 4. For example, three sets of support seats 4 are provided. The hydraulic control system is located inside the machine tool 1. A support plate (not shown in the figure) is installed on the upper end of the slide rail 2. The slide rail 2 is the prior art.

[0022] The hydraulic control system includes an oil tank 5 containing hydraulic oil. The output end of the oil tank 5 is connected to a filter 6 to filter impurities in the hydraulic oil. The output end of the filter 6 is connected to an oil pump 7, and the output end of the oil pump 7 is connected to a main oil pipe 8. An overflow valve 9 is connected to the connecting pipe between the oil pump 7 and the main oil pipe 8. The output end of the overflow valve 9 is connected to the oil tank 5. An accumulator 10 and several sets of hydraulic drive units are connected in parallel on the main oil pipe 8.

[0023] The hydraulic drive unit includes a shut-off valve 11, a directional valve 12, a wiring module, and a hydraulic cylinder 13. The wiring module includes pipe 14, pipe 2 15, pipe 3 16, and pipe 4 17. The shut-off valve 11 is connected to the main oil pipe 8. Pipe 14 connects the shut-off valve 11 to the directional valve 12. The output end of pipe 14 is connected to the directional valve 12. A pressure reducing valve 18 and a speed regulating valve 19 are connected in series on pipe 14. A switching valve 20 is installed outside the pressure reducing valve 18 and the speed regulating valve 19. The series branch formed by the switching valve 20, the pressure reducing valve 18, and the speed regulating valve 19 is connected in parallel. The external drain port of the pressure reducing valve 18 is directly connected to the pipeline of the oil tank 5. The pressure reducing valve 18 is an electromagnetic proportional pressure reducing valve.

[0024] Pipeline 2 15 connects the rodless chamber of hydraulic cylinder 13 to directional valve 12; pipeline 3 16 connects the rod chamber of hydraulic cylinder 13 to directional valve 12; one end of pipeline 4 17 is connected to directional valve 12, and the other end is connected to filter 21. The output end of filter 21 is connected to return pipe 22, and a back pressure valve (not shown in the figure) is connected in series on return pipe 22. Return pipe 22 is connected to oil tank 5. Both pipeline 2 15 and pipeline 3 16 are connected in series with solenoid ball valves 23 (e.g., ...). Figure 5 and Figure 6 (As shown).

[0025] In each group of hydraulic drive units, a machining base 24 is fixedly mounted on the output end of the hydraulic cylinder 13. One group of hydraulic drive units has a clamping device 25 mounted on its machining base 24, which is defined as a clamping unit 29. The machining bases 24 of the other hydraulic drive units are equipped with different air pipe connector processing devices (such as…). Figure 3 As shown), this is defined as processing unit 30. The clamping device 25 and various processing equipment are all existing technologies. The clamping device 25 is a hydraulic chuck, and the processing equipment can be a lathe tool or other equipment depending on the processing scheme of the air pipe connector. For example, Figure 4 The hydraulic control system is equipped with three processing units 30 and one clamping unit 29.

[0026] Both the clamping unit 29 and the processing unit 30 have accumulators 26 connected in parallel at the position between the solenoid ball valve 23 and the hydraulic cylinder 13 on the pipe 15. Figure 5 and Figure 6 As shown), a pressure relay 27 is connected in parallel to the second pipe 15 of the clamping unit 29 at the position between the electromagnetic ball valve 23 and the hydraulic cylinder 13, and a pressure relay 28 is connected in parallel to the third pipe 16 of the processing unit 30 at the position between the electromagnetic ball valve 23 and the hydraulic cylinder 13.

[0027] The hydraulic cylinder 13 of the clamping unit 29 is mounted on the upper end of the support plate of the slide rail 2. The second pipe 15, the third pipe 16 of the clamping unit 29 and the hydraulic lines of the clamping device 25 are integrated and installed inside the cable chain 3 (not shown in the figure). The hydraulic cylinders 13 of each processing unit 30 are respectively installed on the outside of each support base 4, and the pipes 15 and 16 of the processing unit 30 are both located inside the support base 4.

[0028] The power supply module is used to control the on and off of the power supply circuits for each electrical device.

[0029] The shut-off valve 11, reversing valve 12, pressure reducing valve 18, switching valve 20, solenoid ball valve 23, clamping device 25, and each group of pressure relays are all electrically connected to the power supply module.

[0030] A processing method for an intelligent combination processing device for endotracheal connectors includes: Method 1: Workpiece clamping. The workpiece is clamped by the clamping device 25. The hydraulic control system controls the processing seat 24 of the clamping unit 29 to move the workpiece to the processing position and achieve positioning.

[0031] The workpiece to be processed is placed in the clamping position of the clamping device 25, so that the clamping device 25 can clamp the workpiece. Further, the oil pump 7 is started, and the oil pump 7 draws the hydraulic oil in the oil tank 5 into the main oil pipe 8. The shut-off valve 11 of the clamping unit 29 is opened and the switching valve 20 is closed. The hydraulic oil flows through the pressure reducing valve 18 and the speed regulating valve 19 in turn, and then flows into the reversing valve 12. The pressure and flow rate of the hydraulic oil are adjusted by the pressure reducing valve 18 and the speed regulating valve 19 to adapt to the pressure and speed requirements of different processes.

[0032] The reversing valve 12 connects pipe 14 to pipe 2 15, and pipe 3 16 to pipe 4 17. Hydraulic oil flows into the rodless chamber of hydraulic cylinder 13 through pipe 2 15, thereby causing the output end of hydraulic cylinder 13 to push the processing seat 24, which is equipped with clamping device 25, to move. The clamping device 25 drives the workpiece to move closer to the support seat 4. Hydraulic oil flows from the rod chamber into pipe 3 16, and then flows through the reversing valve 12, pipe 4 17 and filter, and flows back to the oil tank 5 through the return oil pipe.

[0033] Furthermore, the solenoid ball valve 23 connected in series with the clamping unit 29 on the second pipeline 15 is closed, locking the oil pressure inside the hydraulic cylinder 13 to achieve the positioning of the clamped workpiece. The hydraulic oil in the rod chamber flows back to the oil tank 5. The accumulator 26 only needs to compensate for the internal leakage of the hydraulic cylinder 13 itself, and is not affected by the internal leakage of the reversing valve 12 and the pressure reducing valve 18, thus maintaining the long-term stability of the oil pressure.

[0034] Method 2: Workpiece processing. After the workpiece is clamped and positioned, the shut-off valves 11 of different processing units 30 are opened in sequence, so that each group of processing units 30 completes the processing in sequence according to the production requirements of the air pipe connector.

[0035] Specifically, the shut-off valve 11 of the processing unit 30 is opened, allowing hydraulic oil to flow into the rodless chamber of the hydraulic cylinder 13 of the processing unit 30. The flow principle of the hydraulic oil is the same as that in step one, causing the output end of the hydraulic cylinder 13 to push the processing seat 24 on which the processing equipment is installed to move, thereby moving the processing equipment to the working position. The solenoid ball valve 23 is activated to ensure the oil pressure in the hydraulic cylinder 13, thereby stabilizing the processing equipment in the working area. The processing equipment is then started to realize the processing of the workpiece.

[0036] Furthermore, when processing the workpiece, it is necessary to adjust the processing position. Therefore, the solenoid ball valve 23 is opened, and the directional valve 12 connects pipe 3 16 with pipe 1 14 and pipe 2 15 with pipe 4 17. At this time, hydraulic oil flows into the rod chamber along pipe 1 14 and pipe 3 16, thereby resetting the output end of the hydraulic cylinder 13. The hydraulic oil delivery path is switched by the directional valve 12 to realize the adjustment of the working position of the processing equipment. During this process, accumulator 1 10 and accumulator 2 26 are used to eliminate pressure fluctuations when the directional valve 12 is working.

[0037] After processing is completed, the reversing valve 12 of the processing unit 30 first controls the hydraulic cylinder 13 to reset. Specifically, the switch valve 20 is opened, and the reversing valve 12 connects pipe 3 16 and pipe 1 14, and pipe 2 15 and pipe 4 17. The hydraulic oil flows directly through the switch valve 20 into the reversing valve 12, realizing the rapid reset of the hydraulic cylinder 13.

[0038] Furthermore, the slide rail 2 drives the clamping unit 29 to move to the next set of processing units 30. The working principle of the subsequent processing units 30 is the same. The hydraulic control system realizes the independent control of multiple sets of independent processing units 30, realizing the automated processing of multiple processes of air pipe connectors without the need to change processing equipment, reducing processing steps and improving processing accuracy.

[0039] Method 3: Based on Examples 1 and 2, a pressure relay is used to determine the station status, enabling multi-level control of the clamping device 25 and the processing equipment, thus avoiding processing defects caused by equipment interference. Specifically, in the clamping unit 29, when the oil pressure in the rodless chamber of the hydraulic cylinder 13 reaches the set value, the pressure relay 27 sends a signal to the power supply module. The power supply module supplies power to each group of electrical equipment in the corresponding processing unit 30 according to the processing requirements of the workpiece, thereby controlling the operation of the processing unit 30.

[0040] When it is necessary to switch between different processing units 30, the previous processing unit 30 is first reset according to the principle in Embodiment 2. During the process of hydraulic oil pushing hydraulic cylinder 13 to reset, when the oil pressure in the rod chamber of hydraulic cylinder 13 reaches the set value, pressure relay 28 sends a signal to the power supply module. After receiving the signal, the power supply module delays and cuts off the power supply to the previous processing unit 30 to ensure the pressure of the previous processing unit 30 is stable, and then supplies power to the next processing unit 30, thereby avoiding the simultaneous operation of different processing units 30 and ensuring that the workpiece is stably clamped during processing.

[0041] After all processing steps are completed, the hydraulic control system first resets the processing unit 30. After all processing units 30 are reset, pressure relay 28 sends a signal to the power supply module. After receiving the signal, the power supply module determines that the processing is complete and transmits a signal to the hydraulic control system. The hydraulic control system controls the clamping unit 29 to reset the workpiece, making it easier for the operator to remove the processed workpiece.
