Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically a single-column CNC vertical lathe. Background Technology

[0002] Single-column CNC vertical lathes are metal cutting equipment widely used in high-end equipment manufacturing fields such as heavy machinery, construction machinery, aerospace, and rail transportation. They are mainly used for machining large disc-shaped, sleeve-shaped, ring-shaped, and irregularly shaped curved surface parts, and are core equipment for achieving high-precision machining of key components. With the upgrading of manufacturing towards intelligence and high-end technology, the machining of large parts places higher demands on the CNC level, machining accuracy, operational stability, and adaptability of equipment. Existing single-column vertical lathes, by integrating CNC systems, servo drive technology, and precision transmission mechanisms, have achieved automated control of the machining process. Their single-column structure, due to its advantages such as small footprint, spacious operating space, and convenient workpiece loading and unloading, occupies an important position in small-batch, high-precision machining scenarios.

[0003] Authorization announcement number CN118720765B discloses a single-column intelligent vertical CNC lathe.

A cooling chamber is fixedly installed on the inner wall of the housing, and the cooling chamber is located on the left side of the workpiece holder. The operation panel is fixedly installed on the housing, and the Z-axis is fixedly installed on the housing. The inner wall of the housing has the X-axis fixedly mounted on the Z-axis, the tool holder fixedly mounted on the X-axis, and the motor fixedly mounted on the bottom of the inner wall of the housing. The turntable is fixedly connected to the output end of the motor. This device solves the problem that current CNC lathes cannot perform efficient, automated, and intelligent cooling when boring workpieces, resulting in poor cooling effect and damage to the boring tool and workpiece. However, in this invention, the tool moves laterally and vertically when expanding the hole of the workpiece, but the angle of the coolant sprayed from the spray pipe is fixed, which makes it impossible to achieve precise cooling and greatly reduces the efficiency of coolant use. Summary of the Invention

[0004] The purpose of this invention is to provide a single-column CNC vertical lathe that can detect the position of the tool holder in real time by using a laser tracker in conjunction with a target.

[0008] Preferably, the cooling mechanism further includes a moving component, which includes a moving rod, a fixed cylinder, a docking groove, and a lead screw. The moving rod is rotatably connected to the middle of the connecting pipe. The end of a cylinder is mounted on the upper surface of the moving rod, and the fixed cylinder is sleeved on the outer surface of the moving rod. A lead screw is rotatably connected through the center of the fixed cylinder. One end of the lead screw is threaded into the inside of the moving rod, and the other end of the lead screw is equipped with a first driving component. The first driving component is installed at the end of the fixed cylinder, and a mating groove is formed on the upper surface of the fixed cylinder to mate with the cylinder.

[0009] Preferably, the cooling mechanism further includes a rotating assembly, which includes an internal gear ring, an external gear ring, a gear set, a first support frame, and a second support frame. The internal gear ring and the external gear ring are rotatably mounted at the center of the bottom of the body cavity through an annular groove. The second support frame is fixedly mounted on the internal gear ring, and the upper part of the second support frame is fixedly mounted on the outer surface of the fixed cylinder. A first support frame is fixedly installed on the outer gear ring. The upper part of the first support frame is installed at the bottom of the laser tracker. The inner gear ring and the outer gear ring are connected by a gear set. A second driving component is installed at the bottom of the gear set.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the single-column CNC vertical lathe; 1. The device is equipped with a tool holder that moves to move the target. When the target moves, the laser tracker will always follow the target and rotate. When the laser tracker rotates, it can measure the position of the tool holder. When the laser tracker measures the position of the tool holder, it can control the cylinder to work. When the cylinder works, it can push the connecting pipe to rotate. When the connecting pipe rotates, it can drive the nozzle to rotate. When the nozzle rotates, the sprayed coolant will always fall on the surface of the tool. This allows the nozzle to adjust the spray angle of the coolant according to the position of the tool, thereby improving the tool cooling effect and the efficiency of coolant use. 2. Equipped with a laser tracker, it can detect the position of the tool holder through a target. When the tool moves away from the nozzle, the laser tracker will send a command to increase the power of the water pump. The increased power of the water pump will increase the speed of the coolant spray. When the tool moves closer to the nozzle, the laser tracker will send a command to decrease the power of the water pump. The decreased power of the water pump will decrease the speed of the coolant spray. In this way, the coolant can always be sprayed on the surface of the tool, which makes it convenient for the water pump to adjust the distance of the coolant spray according to the position of the tool. 3. The system is equipped with a motor that drives a gear set. When the gear set is working, it drives the outer gear ring and the inner gear ring to mesh and rotate. When the outer gear ring and the inner gear ring mesh and rotate, they can drive the first support frame and the second support frame to move in opposite directions. When the first support frame and the second support frame move in opposite directions, they can drive the laser tracker and the fixed cylinder to move. When the fixed cylinder moves, it can drive the connecting pipe and the nozzle to move via the moving rod, so that the laser tracker and the nozzle can be adjusted according to the direction of the cutter head. 4. When the tool is enlarging the workpiece, the air pump can deliver high-pressure air into the second hose, which in turn delivers the high-pressure air into the annular ventilation groove. After the high-pressure air enters the annular ventilation groove, it can be sprayed onto the surface of the tool tip through the jet nozzle, thereby blowing away the debris around the tool and improving the accuracy of the tool's enlarging.

Detailed Implementation

[0015] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0016] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0017] Please see Figures 1-5 The present invention provides an embodiment of a single-column CNC vertical lathe, comprising: a machine body 100, wherein a rotary chuck 200 is rotatably mounted at the center of the bottom of the inner chamber of the machine body 100 via a drive mechanism; a cross-moving mechanism 300 is mounted on the inner wall of the inner chamber of the machine body 100; a tool holder 400 is mounted on the cross-moving mechanism 300; a tool 500 is mounted at the bottom of the tool holder 400; and a cooling mechanism 600 for cooling the tool 500 and a cleaning structure 700 for cleaning debris are respectively installed in the inner chamber of the machine body 100. The cooling mechanism 600 includes a cooling component 610 and a following component 620. It should be understood that after the workpiece is drilled, it is placed on the rotating jaw disk 200 for clamping and fixing. After the workpiece is clamped and fixed, the cross moving mechanism 300 will drive the tool holder 400 and the tool 500 to move vertically and horizontally. When the tool 500 moves to the top of the workpiece hole, the drive mechanism will drive the rotating jaw disk 200 and the workpiece to rotate at high speed. When the workpiece rotates, the tool 500 can enlarge the workpiece hole. When the tool holder 400 enlarges the workpiece hole, it will move vertically or horizontally through the cross moving mechanism 300. When the tool holder 400 moves, the following component 620 will cause the cooling component 610 to follow the movement of the tool holder 400 and adjust the spray angle of the coolant. While the tool 500 enlarges the workpiece hole, the cleaning structure 700 can blow away the debris around the tool 500. Furthermore, the rotating component 640 can adjust the position of the cooling component 610 and the following component 620 by adjusting the angle of the tool head.

[0018] like Figures 1-7 As shown, the cooling assembly 610 includes a connecting pipe 611 and a nozzle 612. The connecting pipe 611 is provided on the left side of the tool holder 400, and the nozzle 612 is installed at the bottom end of the connecting pipe 611. The nozzle 612 can spray coolant onto the surface of the tool 500. It should be noted that the connecting pipe 611 can deliver coolant to the inside of the nozzle 612, and the nozzle 612 can spray coolant onto the back of the tool head 500. When the coolant comes into contact with the tool head, the coolant can cool the tool head.

[0019] like Figures 1-6 As shown, the cooling assembly 610 also includes a first hose 613 and a water pump 614. The top end of the connecting pipe 611 is rotatably connected to the first hose 613 through a sealed bearing. The other end of the first hose 613 is connected to the water pump 614. The water pump 614 is installed on the right side wall of the inner chamber of the machine body 100. The water pump 614 is electrically connected to the laser tracker 623. The input end of the water pump 614 extends to the outside of the machine body 100 and is connected to the outlet of the coolant storage tank provided outside the machine body 100. It is conceivable that when the water pump 614 is working, it can pump the coolant in the coolant storage tank into the first hose 613. The first hose 613 will then deliver the coolant to the connecting pipe 611 and the nozzle 612. The laser tracker 623 can detect the position of the tool holder 400 through the target 624. When the tool 500 moves away from the nozzle 612, the laser tracker 623 will send a power increase command to the water pump 614. After the power of the water pump 614 is increased, the speed of the coolant spray will increase. When the tool 500 moves closer to the nozzle 612, the laser tracker 623 will send a power decrease command to the water pump 614. After the power of the water pump 614 is decreased, the speed of the coolant spray will decrease. Thus, the coolant can always be sprayed on the surface of the tool 500 after spraying.

[0020] like Figures 1-7 As shown, the following component 620 includes a cylinder 622, a laser tracker 623, and a target 624. The cylinder 622 is located on the upper part of the outer surface of the connecting pipe 611, and the laser tracker 623 is located on the right side of the inner chamber of the machine body 100. The laser tracker 623 is a mature product in the existing market, so it is not described in detail. The laser tracker 623 is connected to the cylinder 622. The target 624 is located at the bottom of the tool holder 400. The laser tracker 623 can follow the displacement of the target 624. The laser tracker 623 can send the data of the target 624 to the cylinder 622. When the cylinder 622 receives the data, it will push the connecting pipe 611 and the nozzle 612 to swing. The swinging of the nozzle 612 can keep the coolant sprayed on the tool 500. It is worth noting that when the tool holder 400 moves, it can drive the target 624 to move. When the target 624 moves, the laser tracker 623 will always follow the target 624 to rotate. When the laser tracker 623 rotates, it can measure the position of the tool holder 400. When the laser tracker 623 measures the position of the tool holder 400, it can control the cylinder 622 to work. When the cylinder 622 works, it can push the connecting pipe 611 to rotate. When the connecting pipe 611 rotates, it can drive the nozzle 612 to rotate. When the nozzle 612 rotates, the coolant sprayed out will always fall on the surface of the tool 500. It should be noted here that, Figure 7 As shown in Figure a, when the tool 500 is enlarging the hole in the workpiece, the pre-drilled hole needs to be used as the initial position. The tool 500 will be at the top edge of the pre-drilled hole, and the coolant spray angle will be at the contact point between the tool tip and the top edge of the pre-drilled hole. At this time, if the tool 500 moves downward, the spray angle of the nozzle 612 will not change, and the coolant will be sprayed onto the surface of the tool 500 and flow to the position of the tool tip for cooling. Figure 7As shown in Figure 2bc, when the tool 500 moves laterally to gradually enlarge the hole from top to bottom, the spray angle of the nozzle 612 will be adjusted with the lateral movement of the tool 500. As the diameter of the hole increases, the angle of the coolant sprayed by the nozzle 612 will get closer and closer to the bottom of the hole and the tool head. When the hole reaches the specified diameter, the coolant sprayed by the nozzle 612 can be directly sprayed onto the tool head at the bottom of the hole. At this time, the nozzle 612 will adjust its angle according to the up and down movement of the tool head. The angle adjustment of the nozzle 612 is controlled by the cooperation of the laser tracker 623 and the target 624.

[0021] like Figure 2 and Figure 6 As shown, the following component 620 also includes a movable ring 621, and the output end of the cylinder 622 is rotatably connected to the movable ring 621. The movable ring 621 is movably sleeved on the outer wall of the connecting pipe 611. It is clear that when the cylinder 622 is working, it can push the movable ring 621 to move. When the movable ring 621 moves, it can slide on the outer wall of the connecting pipe 611. While the movable ring 621 slides on the outer wall of the connecting pipe 611, it also pushes the connecting pipe 611 to rotate. When the connecting pipe 611 rotates, the middle part will rotate at the end of the moving rod 631. When the connecting pipe 611 rotates, it can adjust the spray angle of the nozzle 612.

[0022] like Figures 1-6 As shown, the cooling mechanism 600 further includes a moving component 630, which includes a moving rod 631, a fixed cylinder 632, a docking groove 633, and a lead screw 634. The moving rod 631 is rotatably connected to the middle of the connecting pipe 611. The end of the cylinder 622 is mounted on the upper surface of the moving rod 631. The fixed cylinder 632 is sleeved on the outer surface of the moving rod 631. The lead screw 634 is rotatably connected through the center of the fixed cylinder 632. One end of the lead screw 634 is threaded into the interior of the moving rod 631. The other end of the lead screw 634 is equipped with a first driving component, which is mounted on the end of the fixed cylinder 632. The first driving component is generally a motor. The upper surface of the fixed cylinder 632 has a docking groove 633 that is opposite to the cylinder 622. It should be understood that when the cutter holder 400 moves toward the connecting pipe 611, the motor will drive the lead screw 634 to rotate. When the lead screw 634 rotates, it can drive the moving rod 631 to slide threadedly. When the moving rod 631 slides threadedly, it will slide laterally in the fixed cylinder 632. When the moving rod 631 slides laterally, it can drive the cylinder 622 to move. When the moving rod 631 moves, its end can slide inside the docking groove 633. When the cylinder 622 moves, it can drive the connecting pipe 611 and the nozzle 612 to move. Therefore, when the cutter holder 400 moves laterally by a large amount, the connecting pipe 611 and the nozzle 612 can follow suit.

[0023] like Figures 1-3 , Figure 6 As shown, the cooling mechanism 600 further includes a rotating assembly 640, which includes an internal gear ring 641, an external gear ring 642, a gear set 643, a first support frame 644, and a second support frame 645. The internal gear ring 641 and the external gear ring 642 are rotatably mounted at the center of the bottom of the cavity of the body 100 through an annular groove. The second support frame 645 is fixedly mounted on the internal gear ring 641, and the upper part of the second support frame 645 is fixedly mounted on the outer surface of the fixed cylinder 632. The first support frame 644 is fixedly mounted on the external gear ring 642, and the upper part of the first support frame 644 is mounted on the bottom of the laser tracker 623. The internal gear ring 641 and the external gear ring 642 are connected by a gear set 643, which is usually composed of three gears. A second driving component is mounted at the bottom of the gear set 643. The second driving component is installed inside the annular groove at the bottom of the cavity of the body 100. The second driving component is generally a motor. It should be noted that when the cutter 500 is assembled and the cutter head faces the nozzle 612, the motor can drive the first gear to rotate. When the first gear rotates, it will drive the outer gear ring 642 to mesh and rotate. At the same time, the first gear can drive the second gear to mesh and rotate. When the second gear meshes and rotates, it will drive the third gear to mesh and rotate. When the third gear meshes and rotates, it will drive the inner gear ring 641 to mesh and rotate. When the outer gear ring 642 and the inner gear ring 641 mesh and rotate, they can drive the first support frame 644 and the second support frame 645 to move towards each other. When the first support frame 644 and the second support frame 645 move towards each other, they will drive the laser tracker 623 and the fixed cylinder 632 to move. When the fixed cylinder 632 moves, it can drive the connecting pipe 611 and the nozzle 612 to move through the moving rod 631, so that the laser tracker 623 and the nozzle 612 can be adjusted according to the orientation of the cutter head.

[0024] like Figures 1-5As shown, the rotating assembly 640 further includes a rotating groove 646, a first rotating ring 647, and a gear 648. The bottom of the tool holder 400 has a rotating groove 646. The first rotating ring 647 is rotatably mounted inside the rotating groove 646. A target 624 is fixedly mounted on the bottom of the first rotating ring 647. The outer surface of the first rotating ring 647 is meshed with the gear 648 through an annular tooth groove. The outer surface of the gear 648 passes through the inner wall of the rotating groove 646 and is connected to a third driving member. The third driving member can be a motor. The third driving member is mounted on the surface of the tool holder 400. It is conceivable that when the laser tracker 623 is adjusting its position, the motor will drive the gear 648 to rotate. When the gear 648 rotates, it can drive the annular tooth groove of the first rotating ring 647 to mesh and rotate. When the first rotating ring 647 meshes and rotates, it can rotate inside the rotating groove 646. When the first rotating ring 647 rotates, it drives the target 624 at the bottom to rotate, so that the target 624 moves to the corresponding position of the laser tracker 623.

[0025] like Figures 1-6 As shown, the cleaning structure 700 includes a second rotating ring 710, a jet nozzle 720, an annular ventilation groove 730, and a second flexible hose 740. An annular ventilation groove 730 is provided at the axial center of the bottom of the blade holder 400. The second rotating ring 710 is rotatably installed inside the annular ventilation groove 730. The second rotating ring 710 is connected to the first rotating ring 647. A jet nozzle 720 is provided through the bottom of the second rotating ring 710. The second flexible hose 740 is installed at the interface of the annular ventilation groove 730, and the end of the second flexible hose 740 away from the annular ventilation groove 730 extends into the interior of the machine body 100 and is connected to the output end of an air pump fixed inside the machine body 100. It is worth noting that when the tool 500 enlarges the hole of the workpiece, a large amount of debris will fall into the hole and remain at the bottom of the tool 500. When the tool 500 enlarges the hole downwards, the debris can easily block the tool 500, which will affect the accuracy of the enlargement. Therefore, when the tool 500 enlarges the hole of the workpiece, the air pump can deliver high-pressure air into the second hose 740. The second hose 740 will then deliver the high-pressure air into the annular ventilation groove 730. When the high-pressure air enters the annular ventilation groove 730, the high-pressure air can be sprayed onto the surface of the tool 500 tip through the jet nozzle 720, which will blow away the debris around the tool 500. It should be noted that when the first rotating ring 647 drives the target 624 to rotate, it also drives the second rotating ring 710 to rotate. When the second rotating ring 710 rotates, it can adjust the position of the jet nozzle 720.

[0026] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
