Technical Field

[0001] This invention relates to the field of machine tool tool changing technology, specifically to a high-efficiency PLC-driven multi-functional machine tool rapid automated tool changing device. Background Technology

[0002] A PLC (Programmable Logic Controller) is a digital electronic system designed for industrial applications. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations. Through digital or analog inputs and outputs, it controls various types of mechanical equipment or production processes. Multi-functional machine tools are among the more complex CNC machine tools, possessing multiple machining capabilities such as milling, drilling, and boring. To improve production efficiency and machining accuracy, multi-functional machine tools require rapid automated tool changing devices to reduce non-cutting time during machining. However, existing PLC-driven rapid automated tool changing devices for multi-functional machine tools cannot stably fix the machine tools, reducing the safety of tool changes.

[0003] The existing PLC-driven multi-functional machine tool rapid automated tool changer has the following drawbacks: 1. Patent document CN117773632A discloses an automated tool changer, "including a control box and a central shaft. A tool changer support arm is provided at the bottom of the central shaft. Locking devices are provided at both diagonal ends of the tool changer support arm. The locking devices include a concave part with a semi-circular support inside and two arc-shaped rods outside the concave part. A push seat is provided in the middle of the concave part. A horizontal seat is provided at the bottom of the central shaft with locking shafts at both ends. Locking holes are provided on the arc-shaped rods. A return spring is provided between the horizontal seat and the tool changer support arm. A limit frame is fixed at the bottom of the control box. This invention uses a "C" shaped buckle formed by two arc-shaped rods to fix the tool more stably; by locking and unlocking the "C" shaped buckle during the lifting and lowering of the tool changer support arm, high-speed tool changing is ensured during the 180° tool changing phase of the tool changer support arm; by improving the tool installation efficiency and tool changing efficiency, tool replacement is made safer and more efficient." However, existing PLC-driven multi-functional machine tool rapid automated tool changers cannot stably fix the machine tool, reducing the safety of tool replacement. 2. Patent document CN114952370A discloses a tool holder and its automated tool changer, "including: a protective cover, a transmission mechanism, and a cleaning mechanism. An extension block is fixedly installed on one side of the protective cover, and mounting ears are fixedly installed on both ends of the extension block. The bottom ends of the two mounting ears are rotatably connected to the two ends of the mounting plate through a rotating shaft. The tool holder and its automated tool changer provided by this invention realize synchronous tool changing rotation of the protective cover on the tool holder through the transmission mechanism on the equipment. In addition, the equipment is equipped with a cleaning mechanism to clean the tools on the tool holder. Furthermore, the cooperation between the transmission mechanism and the cleaning mechanism facilitates the protection and cleaning of the tools. The protective cover is rotated and the tools are cleaned by the self-power of the CNC machine tool spindle. The protection and cleaning of the tools are completed without an additional power source." However, existing PLC-driven multi-functional machine tool rapid automated tool changers cannot change tools quickly and accurately, thus reducing the tool change speed. 3.

Its technical solution enables automated tool changing and adjustment of the machining feed rate according to the workpiece machining state at each stage, which is convenient, reliable, and highly accurate, greatly reducing the workload of operators." However, the tool changing components of existing PLC-driven multi-functional machine tool rapid automated tool changing devices cannot be automatically lubricated, reducing their service life. 4. Patent document CN219403424U discloses an automated tool magazine automatic tool changer, "including a mounting frame, a tool magazine is provided on the top of one side of the mounting frame, a hydraulic rod is provided on the surface of the mounting frame, a slider is provided at the bottom of the hydraulic rod, guide rods are symmetrically provided on the adjacent sides of the hydraulic rod, and through holes for the guide rods to pass through are symmetrically opened on the top edge of the slider, and mounting bolts are symmetrically provided on the bottom side of the mounting frame; the designed functional components facilitate the reduction of friction between the slider and the guide rods during movement, and also facilitate the lubrication of the surface of the guide rods, so that the slider can maintain a good operating condition." However, the existing PLC-driven multi-functional machine tool rapid automated tool changer cannot quickly remove the debris from the surface of the machine tool, which reduces the machining quality of the PLC-driven multi-functional machine tool.

[0013] Preferably, the second cleaning head is located below the first cleaning head, and the sliding sleeve moves with the support of the sliding rod.

[0014] Preferably, the method of using the tool changing device includes the following steps: Step S1: After the machine tool cutter enters the placement cylinder, the No. 1 motor rotates, driving the gear to rotate. The gear rotates, driving the rack to move. The rack moves, driving the No. 1 T-shaped frame to move. The No. 1 T-shaped frame moves, driving the No. 1 slide rail to move. The slide rail moves, driving the pulley to rotate. The pulley rotates, allowing the No. 1 T-shaped frame to move stably through the No. 1 opening. The movement of the No. 1 T-shaped frame drives the pressure pad to move. The pressure pad presses the machine tool cutter against the support seat for quick fixation. After fixation, it facilitates the quick replacement of the machine tool cutter, realizing the function of stable fixation of the machine tool cutter and improving the safety of replacement. Step S2: When the PLC processing module detects an excessive distance, it controls the tool changer to shorten. After the tool changer shortens, the infrared height sensor continuously monitors the real-time height data within the tool changer until the PLC processing module detects a suitable distance or an excessive distance. When the PLC processing module detects an excessive distance, it controls the tool changer to extend. After the tool changer extends, the infrared height sensor continuously monitors the real-time height data within the tool changer until the PLC processing module detects a suitable distance or an excessive distance. When the PLC processing module detects a suitable distance, it controls the tool changer to stop. After the tool changer stops, the infrared height sensor continuously monitors the real-time height data within the tool changer until the PLC processing module detects an excessive distance or an excessive distance. This achieves the function of rapid and accurate tool changing on the machine tool, improving the tool changing speed. Step S3: Lubricating oil enters the No. 1 box through the oil inlet head. The No. 3 motor rotates, driving the push head to rotate. The rotation of the push head drives the π-shaped frame to move. The movement of the π-shaped frame drives the sealing head to move. The movement of the sealing head drives the No. 1 spring to move. The movement of the No. 1 spring causes the sealing head to move away from the support ring. At this time, the lubricating oil flows through the gap between the support ring and the sealing head into the outlet head. The lubricating oil is discharged through the outlet head to the surface of the tool changing assembly for automatic lubrication. This realizes the function of automatic lubrication of the tool changing assembly of the machine tool's rapid and automated tool changing device, thereby improving its service life. Step S4: When the machine tool cutter enters the No. 2 box through the through-hole, the pneumatic head starts and drives the T-shaped head to move. The movement of the T-shaped head drives the sliding sleeve to move. The movement of the sliding sleeve causes the T-shaped head to drive the No. 5 spring to move. The movement of the No. 5 spring causes the T-shaped head to drive the No. 1 cleaning head to move. The movement of the No. 1 cleaning head causes the machine tool cutter to press against the No. 2 cleaning head. At this time, during the movement of the machine tool cutter, the debris on its surface is removed, realizing the function of quickly removing debris from the surface of the machine tool cutter and improving the processing quality of the PLC-driven multi-functional machine tool.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention involves installing a machine tool cutter into a placement cylinder. A first motor rotates, driving a gear to rotate. The gear rotates, causing a rack to move. The rack moves, causing a first T-shaped frame to move. The first T-shaped frame moves, causing a first slide rail to move. The slide rail moves, causing a pulley to rotate. The pulley rotates, allowing the first T-shaped frame to move stably through a first opening. The movement of the first T-shaped frame causes a pressure pad to move, pressing the machine tool cutter against the support seat for quick fixation. This fixation facilitates rapid tool replacement, achieving stable tool fixation and improved replacement safety. 2. This invention, through the installation of a PLC processing module, detects an excessively large distance and controls the tool changing assembly to shorten. After the tool changing assembly shortens, an infrared height sensor continuously monitors the real-time height data within the tool changing assembly until the PLC processing module detects a suitable distance or an excessively small distance. If the PLC processing module detects an excessively small distance, it controls the tool changing assembly to extend. After the tool changing assembly extends, the infrared height sensor continuously monitors the real-time height data within the tool changing assembly until the PLC processing module detects a suitable distance or an excessively large distance. If the PLC processing module detects a suitable distance, it controls the tool changing assembly to stop. After the tool changing assembly stops, the infrared height sensor continuously monitors the real-time height data within the tool changing assembly until the PLC processing module detects an excessively small or excessively large distance. This achieves the function of rapid and accurate tool changing for machine tools, improving tool changing speed. 3. This invention involves installing a lubricating oil inlet head into the first box, where a third motor rotates to drive a push head, which in turn moves a π-shaped frame, which in turn moves a sealing head, which in turn moves a first spring. The movement of the first spring causes the sealing head to move away from the support ring, allowing the lubricating oil to flow through the gap between the support ring and the sealing head into the outlet head. The lubricating oil is then discharged through the outlet head onto the surface of the tool changing assembly for automatic lubrication, thus realizing the function of automatic lubrication of the tool changing assembly in the machine tool's rapid and automated tool changing device, thereby improving its service life. 4. In this invention, when a machine tool cutter enters the second chamber through the through-hole, the pneumatic head starts and drives the T-shaped head to move. The movement of the T-shaped head drives the sliding sleeve to move, which in turn causes the T-shaped head to drive the fifth spring to move. The movement of the fifth spring causes the T-shaped head to drive the first cleaning head to move, and the movement of the first cleaning head causes the machine tool cutter to press against the second cleaning head. At this time, during the movement of the machine tool cutter, the debris on its surface is removed, thus realizing the function of quickly removing debris from the surface of the machine tool cutter and improving the processing quality of the PLC-driven multi-functional machine tool.

The machine door 3 is opened to place the material into the PLC-driven multi-functional machine tool. When a tool change is required, the PLC processing module 7 controls the electric telescopic rod 4 to start, driving the first support frame 5 to move. The movement of the first support frame 5 drives the placement frame 11 to move, aligning the tool pressing assembly with the pressure bar 8.

The PLC processing module 7 is electrically connected to the tool changing component and the infrared height sensor 24. The infrared height sensor 24 is located on the inner wall of the housing 1 and above the placement frame 11. The infrared height sensor 24 is used to detect the real-time height data of the placement frame 11. The PLC processing module 7 has built-in suitable height data of the placement frame 11, which is the parallel position data with the tool holder head 9. The real-time height data of the placement frame 11 is transmitted to the PLC processing module 7. The PLC processing module 7 compares the real-time height data of the placement frame 11 with the suitable height data of the placement frame 11. If the real-time height data of the placement frame 11 is within the suitable height data set as a suitable distance, the real-time height data of the placement frame 11 is greater than the suitable height data set as a suitable distance.

The first cleaning head 44 is located on the T-shaped head 40. The outer wall of 43, the second cleaning head 40 is located on the inner wall of the second box 35, and the second cleaning head 40 is located below the first cleaning head 44. The sliding sleeve 37 moves with the support of the sliding rod 36. When the machine tool tool enters the second box 35 through the through hole 39, the pneumatic head 41 starts and drives the T-shaped head 43 to move. The movement of the T-shaped head 43 drives the sliding sleeve 37 to move. The movement of the sliding sleeve 37 causes the T-shaped head 43 to drive the fifth spring 42 to move. The movement of the fifth spring 42 causes the T-shaped head 43 to drive the first cleaning head 44 to move. The movement of the first cleaning head 44 causes the machine tool tool to press against the second cleaning head 40. At this time, the debris on the surface of the machine tool tool is removed during the movement of the machine tool tool, realizing the function of quickly removing debris from the surface of the machine tool tool and improving the processing quality of the PLC-driven multi-functional machine tool.

[0025] The method of using this tool changer includes the following steps: Step S1: After the machine tool cutter enters the placement cylinder 12, the first motor 21 rotates, driving the gear 22 to rotate. The gear 22 rotates, driving the rack 20 to move. The rack 20 moves, driving the first T-shaped frame 16 to move. The first T-shaped frame 16 moves, driving the first slide rail 17 to move. The slide rail 17 moves, driving the pulley 19 to rotate. The pulley 19 rotates, allowing the first T-shaped frame 16 to move stably through the first opening 14. The movement of the first T-shaped frame 16 drives the pressure pad 23 to move. The pressure pad 23 presses the machine tool cutter against the support seat 13 for quick fixation. After fixation, it facilitates the quick replacement of the machine tool cutter, realizing the function of stable fixation of the machine tool cutter and improving the safety of replacement. Step S2: When the PLC processing module 7 detects an excessively large distance, it controls the tool changing assembly to shorten. After the tool changing assembly shortens, the infrared height sensor 24 continuously monitors the real-time height data within the tool changing assembly until the PLC processing module 7 detects a suitable distance or an excessively small distance. When the PLC processing module 7 detects an excessively small distance, it controls the tool changing assembly to extend. After the tool changing assembly extends, the infrared height sensor 24 continuously monitors the real-time height data within the tool changing assembly until the PLC processing module 7 detects a suitable distance or an excessively large distance. When the PLC processing module 7 detects a suitable distance, it controls the tool changing assembly to stop. After the tool changing assembly stops, the infrared height sensor 24 continuously monitors the real-time height data within the tool changing assembly until the PLC processing module 7 detects an excessively small or excessively large distance. This achieves the function of rapid and accurate tool changing for the machine tool, improving the tool changing speed. Step S3: Lubricating oil enters the first box 25 through the oil inlet head. The third motor 27 rotates, driving the push head 28 to rotate. The rotation of the push head 28 drives the π-shaped frame 31 to move. The movement of the π-shaped frame 31 drives the sealing head 34 to move. The movement of the sealing head 34 drives the first spring 33 to move. The movement of the first spring 33 causes the sealing head 34 to move away from the support ring 29. At this time, the lubricating oil flows through the gap between the support ring 29 and the sealing head 34 to the outlet head 26. The lubricating oil is discharged through the outlet head 26 to the surface of the tool changing assembly for automatic lubrication. This realizes the function of automatic lubrication of the tool changing assembly of the machine tool's rapid automatic tool changing device, thereby improving its service life. In step S4, when the machine tool cutter enters the second box 35 through the through-hole 39, the pneumatic head 41 starts and drives the T-shaped head 43 to move. The movement of the T-shaped head 43 drives the sliding sleeve 37 to move. The movement of the sliding sleeve 37 causes the T-shaped head 43 to drive the fifth spring 42 to move. The movement of the fifth spring 42 causes the T-shaped head 43 to drive the first cleaning head 44 to move. The movement of the first cleaning head 44 causes the machine tool cutter to press against the second cleaning head 40. At this time, during the movement of the machine tool cutter, the debris on its surface is removed, realizing the function of quickly removing debris from the surface of the machine tool cutter and improving the processing quality of the PLC-driven multi-functional machine tool.

[0026] Working principle: Opening the machine door 3 allows materials to be placed into the PLC-driven multi-functional machine tool. When a tool change is needed, the PLC processing module 7 controls the electric telescopic rod 4 to move the first support frame 5. The movement of the first support frame 5 moves the placement frame 11, aligning the tool pressing assembly with the pressure bar 8. At this time, the pressure bar 8 activates, moving the tool clamping head 9. The tool clamping head 9 clamps or removes the machine tool into the tool pressing assembly. When changing the tool, the first servo motor 10 rotates, driving the placement frame 11 to rotate. The rotation of the placement frame 11 changes the position of the tool pressing assembly. There are several tool pressing assemblies, each containing a different machine tool. After the machine tool enters the placement cylinder 12, the first motor 21 rotates, driving the gear 22 to rotate. The rotation of the gear 22 drives... The moving rack 20 moves, which in turn moves the first T-shaped frame 16. The first T-shaped frame 16 moves, which in turn moves the first slide rail 17. The first slide rail 17 moves, which in turn rotates the pulley 19. The rotation of the pulley 19 allows the first T-shaped frame 16 to move stably through the first opening 14. The movement of the first T-shaped frame 16 moves the pressure pad 23, which presses the machine tool tool against the support seat 13 for quick fixation. After fixation, it facilitates the rapid replacement of the machine tool tool, achieving the function of stable fixation of the machine tool tool and improving the safety of tool replacement. When the PLC processing module 7 detects that the distance is too large, it controls the tool changing assembly to shorten. After the tool changing assembly shortens, the infrared height sensor 24 continuously monitors the real-time height data within the tool changing assembly until the distance is reduced. The PLC processing module 7 detects either a suitable distance or a distance that is too small. When the distance is too small, the PLC processing module 7 controls the tool changer assembly to extend. After the tool changer assembly extends, the infrared height sensor 24 continuously monitors the real-time height data within the tool changer assembly until the PLC processing module 7 detects a suitable distance or a distance that is too large. When the distance is suitable, the PLC processing module 7 controls the tool changer assembly to stop. After the tool changer assembly stops, the infrared height sensor 24 continues to monitor the real-time height data within the tool changer assembly until the PLC processing module 7 detects a distance that is too small or too large. This achieves the function of rapid and accurate tool changing, improving the tool changing speed. Lubricating oil is introduced through the oil inlet. When the tool head enters the first box 25, the third motor 27 rotates, driving the push head 28 to rotate. The push head 28 rotates, causing the π-shaped frame 31 to move. The movement of the π-shaped frame 31 causes the sealing head 34 to move. The movement of the sealing head 34 causes the first spring 33 to move. The movement of the first spring 33 causes the sealing head 34 to move away from the support ring 29. At this time, the lubricating oil flows through the gap between the support ring 29 and the sealing head 34 into the outlet head 26. The lubricating oil is discharged through the outlet head 26 to the surface of the tool changing assembly for automatic lubrication. This realizes the function of automatic lubrication of the tool changing assembly of the machine tool's rapid and automated tool changing device, improving its service life. When the machine tool enters the second box 35 through the through-hole 39, the pneumatic head 41 starts, driving the T-shaped head 43 to move. The movement of the T-shaped head 43 drives the sliding sleeve 37 to move.The movement of the sliding sleeve 37 causes the T-shaped head 43 to move, which in turn moves the fifth spring 42. The movement of the fifth spring 42 then causes the T-shaped head 43 to move the first cleaning head 44. The movement of the first cleaning head 44 causes the machine tool cutter to press against the second cleaning head 40. During this process, debris is removed from the surface of the machine tool cutter, thus achieving rapid debris removal and improving the processing quality of the PLC-driven multi-functional machine tool.
