Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machining equipment with tool magazines, in particular to a five-axis five-link machining center with a tool magazine. BACKGROUND

[0002] Generally, in the process of workpiece machining, a variety of tools need to be used, and therefore the machining equipment generally needs to have a tool magazine. The function of the tool magazine is to store various tools required in the machining process.

[0003] Patent No. CN207577981U discloses a machining equipment with a tool magazine. The outer side wall of the disc-type base is uniformly provided with a plurality of outer radial tool taking seats. The cross section of the inner radial tool taking seat is in the shape of a U with an opening pointing to the center of the circle. The cross section of the outer radial tool taking seat is in the shape of a U with an opening away from the center of the circle. The inner radial tool taking seat and the outer radial tool taking seat store tools. The number of tools stored in the tool magazine is increased, which is convenient for practical application.

[0004] However, the above-mentioned prior art has the following technical defects:

[0005] Firstly, the prior art only simply puts the tools into the inner radial tool taking seat or the outer radial tool taking seat without fixing the tools. Therefore, in the process of machining, the vibration generated by the operation of the device may cause the tools to vibrate and collide with the seats, resulting in collision noise. In addition, the frequent collision of the tool shanks with the seats may cause the conical surface of the tool shanks to be scratched or deformed, affecting their normal use and causing economic losses.

[0006] Secondly, the prior art does not clean the machining waste adhering to the surface of the tools. After being used several times, the surface of the tools may adhere to a lot of machining metal waste. These tools with adhering waste may scratch the surface of the workpiece in the process of machining, reducing the quality of the finished product. At the same time, the waste that is not cleaned in time may cause the tool to collapse, resulting in the machining equipment being unable to be used and reducing the work efficiency.

[0007] In summary, the prior art still has room for improvement in reducing the damage of tool shanks and cleaning the dust on the surface of the tools. Therefore, the person skilled in the art proposes a device that can fix the tools in the tool magazine and clean the dust on the surface of the tools after they are used and returned to the tool magazine.

[0040] The following combination Figure 1 - Figure 13 The embodiments of this application will be described in detail.

[0041] This application discloses a five-axis five-linkage machining center with a tool magazine, which can fix the tools placed in the tool magazine, avoiding the situation where the tool holder collides with the device components due to the vibration of the tool during the operation of the device, which would cause scratches on the surface. This extends the service life of the tool holder and reduces economic losses. At the same time, the fixation can be released by rotating the tool to the notch of the limit ring, which makes it convenient for the machining mechanism to pick up and put in the corresponding tool.

[0042] Example 1:

[0043] like Figures 1-3 As shown, the device includes a machining mechanism 2, on which a tool magazine mechanism 3 is provided. The tool magazine mechanism 3 includes a circular cover 301 with an open top. A circular plate 302 is rotatably mounted on the upper end of the circular cover 301. Multiple circumferentially evenly distributed stepped grooves 303 are opened on the upper side of the circular plate 302. Each stepped groove 303 contains a tool 317, and each tool 317 has a different model. A set of clamps 311 adapted to the conical surface of the tool shank of the tool 317 is provided at the end of the stepped groove 303. The tool magazine mechanism 3 stores a variety of different models of tools 317 and provides tools 317 for machining in the machining mechanism 2. The tool shank of the corresponding tool 317 can be clamped and fixed by the set of clamps 311.

[0044] like Figure 3 As shown, a U-shaped frame 304 is laid flat on the side of the round cover 301. A rotary motor 305 with its drive end connected to the center of the upper side of the round plate 302 is installed on the upper side of the U-shaped frame 304. The running rotary motor 305 can drive the round plate 302 to rotate.

[0045] like Figure 3 and Figure 4 As shown, a fixed seat 306 is installed on one side of each stepped groove 303 on the upper side of the circular plate 302. The fixed seat 306 is divided into two chambers, left and right, and a push plate 307 is slidably installed in each chamber. A connecting pipe 313 communicating with the right chamber is installed on the inner wall of the left chamber, and the connection between the connecting pipe 313 and the right chamber is close to the right end. Hydraulic oil is installed in the left chamber. When the T-shaped plate 309 moves to the right, it will drive the push plate 307 in the left chamber to move to the right, and press the hydraulic oil in it into the right chamber through the connecting pipe 313, thereby pushing the push plate 307 in the right chamber to move to the left, so that the two push plates 307 move closer to each other.

[0046] like Figure 3 and Figure 4As shown, a round rod 308 extending to the outside of the fixed seat 306 is installed on the side of the push plate 307. A T-shaped plate 309 and an L-shaped plate 310 are respectively installed at the ends of the two round rods 308. The T-shaped plate 309 and the L-shaped plate 310 are connected to the clamps 311 on the same side of the corresponding group. The two push plates 307 that are close to each other drive the T-shaped plate 309 and the L-shaped plate 310 to move closer to each other through the round rods 308, thereby driving the two clamps 311 to move closer to each other to clamp the tool holder of the tool 317.

[0047] like Figure 3 and Figure 4 As shown, a return spring 312 is installed between the L-shaped plate 310 and the fixed base 306. When the clamps 311 approach each other, the L-shaped plate 310 will compress the return spring 312. When the return spring 312 rebounds, it will drive the right push plate 307 to move to the right. Then, the push plate 307 in the right chamber will push the hydraulic oil back to the left chamber, causing the push plate 307 inside to move to the left, so that the two clamps 311 move away from each other.

[0048] like Figure 3 and Figure 4 As shown, a square plate 318 is mounted on the side of the T-shaped plate 309. A guide wheel 314 is rotatably mounted on the lower side of the square plate 318. A limiting ring 315 with a notch is mounted on the upper center of the circular plate 302. An arc plate 316 is mounted on one end of the limiting ring 315. When the guide wheel 314 is in the notch of the limiting ring 315, the return spring 312 is at its normal length. When the circular plate 302 rotates counterclockwise, the guide wheel 314 will first contact the arc plate 316. The arc plate 316 guides the guide wheel 314 to move towards the fixed seat 306, thereby pushing the T-shaped plate 309 to move towards the fixed seat 306 until the clamp 311 clamps the tool 317. At this time, the guide wheel 314 moves onto the limiting ring 315.

[0049] In summary, the tool magazine mechanism 3 can store various types of cutting tools 317. By rotating the circular plate 302 counterclockwise using the rotary motor 305, the required cutting tool 317 is positioned on one side of the notch in the limiting ring 315. At this time, the corresponding clamp 311 does not hold the cutting tool 317; it can be directly removed for use. After use, it is placed back into the corresponding stepped groove 303. The counterclockwise rotation of the circular plate 302 will drive its corresponding guide wheel 314 to rotate. The guide wheel 314 will first contact the arc-shaped plate 316, which guides the guide wheel 314 towards the solid surface. The fixed seat 306 moves, thereby pushing the T-shaped plate 309 to move towards the fixed seat 306. When the T-shaped plate 309 moves to the right, it will drive the push plate 307 in the left chamber to move to the right, and press the hydraulic oil in it into the right chamber through the connecting pipe 313, thereby pushing the push plate 307 in the right chamber to move to the left, so that the two push plates 307 move closer to each other, and drive the two clamps 311 to move closer to each other to clamp the tool 317 handle. At this time, the guide wheel 314 moves to the limit ring 315, and the limit ring 315 limits the guide wheel 314. At the same time, the L-shaped plate 310 compresses the return spring 312.

[0050] Then, the counterclockwise rotating circular plate 302 drives the tool 317 to be used to move to the side of the notch of the limiting ring 315. The corresponding guide wheel 314 is no longer limited by the limiting ring 315, so the return spring 312 rebounds and drives the push plate 307 on the right side of the tool magazine mechanism 3 to move to the right, pushing the hydraulic oil in the right chamber back to the left chamber, driving the push plate 307 inside to move to the left, so that the two clamps 311 move away from each other and release the clamp on the tool 317.

[0051] like Figure 1 and Figure 5 As shown, the machining mechanism 2 includes a Y-axis base 201, a Y-axis screw 202 rotatably mounted on the upper side of the Y-axis base 201, and a Y-axis motor 203 whose drive end is connected to one end of the Y-axis screw 202 is also fixedly mounted on the upper side of the Y-axis base 201. A Y-axis threaded seat 204 slidably connected to the Y-axis base 201 is provided on the Y-axis screw 202, and an X-axis seat 205 is mounted on the upper side of the Y-axis threaded seat 204. The running Y-axis motor 203 drives the Y-axis screw 202 to rotate, and while driving the Y-axis threaded seat 204 to move, it also drives the X-axis seat 205 to perform axial movement along the Y-axis.

[0052] like Figure 6 As shown, an X-axis screw 206 is rotatably mounted on the upper side of the X-axis seat 205. An X-axis motor 207 with its drive end connected to one end of the X-axis screw 206 is also mounted on the upper side of the X-axis seat 205. An X-axis threaded seat 208 is provided on the X-axis screw 206 and is slidably connected to the X-axis seat 205. An X-axis upper plate 209 connected to the circular plate 302 is mounted on the upper side of the X-axis threaded seat 208. The running X-axis motor 207 drives the X-axis screw 206 to rotate, and while driving the X-axis threaded seat 208 to move, it also drives the X-axis upper plate 209 to perform axial movement of the X-axis.

[0053] like Figure 7 As shown, a C-axis motor 210 is installed on the upper side of the X-axis plate 209 on one side of the circular plate 302. A clamping seat 211 is installed on the drive end of the C-axis motor 210. The workpiece is fixed on the clamping seat 211. The workpiece can be rotated around the C-axis by driving the clamping seat 211 to rotate through the C-axis motor 210.

[0054] like Figure 6 and Figure 7 As shown, a Z-axis side seat 212 is mounted on the upper side of the Y-axis base 201, on the side of the X-axis base 205. A Z-axis screw 213 is rotatably mounted on the side of the Z-axis side seat 212. A Z-axis motor 214, whose drive end is connected to one end of the Z-axis screw 213, is also fixedly mounted on the side of the Z-axis side seat 212. A Z-axis threaded seat 215, which is slidably connected to the Z-axis side seat 212, is mounted on the Z-axis motor 214. A Z-axis side plate 216 is mounted on the side of the Z-axis threaded seat 215. The running Z-axis motor 214 drives the Z-axis screw 213 to rotate, and while driving the Z-axis threaded seat 215 to move, it also drives the Z-axis side plate 216 to perform axial movement of the Z-axis.

[0055] like Figure 6 and Figure 7 As shown, an A-axis electric cylinder 217 is mounted on the side of the Z-axis side plate 216. A machining motor 218 is mounted on the lower end of the A-axis electric cylinder 217. A chuck 219 is mounted on the drive end of the machining motor 218. The tool 317 is fixed by the chuck 219. The extension and retraction of the A-axis electric cylinder 217 drives the tool 317 to move axially along the A-axis. The running A-axis electric cylinder 217 drives the tool 317 to rotate and process the workpiece.

[0056] It should be noted that the machining mechanism 2 is also equipped with an RTCP function, which allows the workpiece to move synchronously on multiple axes while keeping the tip of the tool 317 stationary relative to the workpiece coordinate system.

[0057] In summary, the X-axis upper plate 209 moves around the X-axis to move the tool 317 to be used directly below the chuck 219. Then, the A-axis electric cylinder 217 extends, causing the chuck 219 to descend and fix the tool 317. After that, it shortens, causing the tool 317 to move out of the tool magazine mechanism 3. The X-axis upper plate 209 continues to move around the X-axis to move the workpiece below the tool 317. The A-axis electric cylinder 217 extends and the machining motor 218 runs, driving the tool 317 to rotate and process the workpiece. The moving Y-axis threaded seat 204 drives the workpiece to move along the Y-axis. The X-axis upper plate 209 drives the workpiece to move along the X-axis. The running C-axis motor 210 drives the workpiece to rotate around the C-axis. The Z-axis side plate 216 drives the tool 317 to move around the Z-axis. With the assistance of the RTCP function, the workpiece moves synchronously on multiple axes while keeping the tool tip of the tool 317 stationary relative to the workpiece coordinate system.

[0058] like Figure 8 and Figure 9 As shown, it also includes a cleaning mechanism 4 and a chip collection mechanism 5. The cleaning mechanism 4 includes a rotating cylinder 401 rotatably installed at the lower port of each stepped groove 303. A quarter-circle arc-shaped rack 403 is installed inside the round cover 301. A gear 402 adapted to the arc-shaped rack 403 is installed on the side of the rotating cylinder 401. When the used tool 317 is put back into the stepped groove 303, the cutting body of the tool 317 extends into the rotating cylinder 401. When the round plate 302 rotates counterclockwise, it drives the rotating cylinder 401 corresponding to the tool 317 to move. When the gear 402 on the rotating cylinder 401 meshes with the arc-shaped rack 403, the moving rotating cylinder 401 will rotate by the gear 402 and the arc-shaped rack 403.

[0059] like Figure 8 and Figure 9 As shown, a cylinder 404 is installed inside the rotating cylinder 401. Multiple bundles of evenly distributed soft bristles 405 are installed on the inner side of the cylinder 404. During the rotation of the rotating cylinder 401, the soft bristles 405 inside it are rotated, and the rotating soft bristles 405 are used to clean the waste chips adhering to the surface of the tool body 317.

[0060] like Figure 8 and Figure 10 As shown, the chip collection mechanism 5 includes an upper cover 501 embedded in the center of the lower side of the circular cover 301 and rotatably connected thereto. A collection box 502 is provided on the lower side of the upper cover 501 and is threadedly connected thereto. A suction nozzle 503 is provided at the bottom of the rotating cylinder 401. A conveying pipe 504 communicating with the upper cover 501 is installed at the output end of the suction nozzle 503. The suction nozzle 503, which generates negative pressure at the port, can suck in the waste chips cleaned by the soft hair 405 and convey them to the collection box 502 through the conveying pipe 504.

[0061] like Figure 8 and Figure 10 As shown, an air cylinder 505 is fixedly installed inside the circular cover 301. A piston 514 adapted to the air cylinder 505 is slidably installed inside the air cylinder 505. An extension tube 506 is installed at the center of the lower side of the air cylinder 505, passing through the upper cover 501 and extending into the collection box 502. The extension tube 506 is fixedly connected to the upper cover 501. Multiple evenly distributed through holes are opened on the side of the extension tube 506, and a dustproof net is sleeved on the outside of the extension tube 506. The upward-moving piston 514 draws air from the collection box 502 into the air cylinder 505 through the extension tube 506, thereby generating negative pressure at the ports of each suction nozzle 503. At the same time, the dustproof net prevents waste from entering the extension tube 506 through the through holes.

[0062] like Figure 8 and Figure 10As shown, an air outlet pipe 509 is installed on the side of the air cylinder 505 near the bottom. Both the air outlet pipe 509 and the extension pipe 506 are equipped with one-way valves 508. The one-way valve 508 on the extension pipe 506 only allows gas to enter through the extension pipe 506 and cannot discharge it. The one-way valve 508 on the air outlet pipe 509 only allows gas to discharge through it and cannot enter it.

[0063] like Figure 11 As shown, an L-shaped seat 510 is installed on the upper side of the air cylinder 505, and a turntable 511 is rotatably installed on the side of the L-shaped seat 510. An extension rod 513 extending from the upper side of the air cylinder 505 to the outside is installed at the upper center of the piston 514. A connecting rod 512, whose lower end is rotatably connected to the upper end of the extension rod 513, is rotatably installed on the side edge of the turntable 511. The rotating turntable 511 pulls the piston 514 up and down through the connecting rod 512 and the extension rod 513.

[0064] like Figure 11 As shown, a second gear 515 is installed at the lower center of the circular plate 302, and a third gear 516, which is much smaller than the second gear 515 and meshes with it, is installed on the upper side of the L-shaped seat 510. The shaft of the third gear 516 and the shaft of the turntable 511 are equipped with meshing bevel teeth 517. When the circular plate 302 rotates, the third gear 516 is driven to rotate through the second gear 515. The rotating third gear 516 drives the turntable 511 to rotate through the two bevel teeth 517.

[0065] In summary, after the tool 317 is reinserted into the corresponding stepped groove 303, and other types of tools 317 are rotated to the side of the notch on the limiting ring 315, the gear 402 on the rotating cylinder 401 corresponding to the inserted tool 317 will mesh with the arc-shaped rack 403, causing the rotating cylinder 401 to rotate as it moves with the circular plate 302. The rotating cylinder 401 will clean the debris adhering to the surface of the tool 317 through the soft bristles 405. At the same time, the rotating circular plate 302 drives the gear 516 to rotate through the gear 515. The rotating gear 516 drives the turntable 511 to rotate through the two bevel teeth 517. The rotating turntable 511... The piston 514 is moved up and down by the connecting rod 512 and the extension rod 513. During the upward movement, the piston 514 draws air from the collection box 502 into the air cylinder 505 through the extension tube 506, thereby generating negative pressure at the ports of each suction nozzle 503. The suction nozzle 503 with negative pressure at the port can suck in the waste debris cleaned by the soft bristles 405 and transport it to the collection box 502 through the conveying tube 504. At the same time, the dustproof net is used to prevent waste debris from entering the extension tube 506 through the through hole. During the downward movement of the piston 514, the gas in the air cylinder 505 is discharged through the air outlet tube 509. When the circular plate 302 stops rotating, the chip collection mechanism 5 stops working.

[0066] Example 2:

[0067] Based on Example 1, such asFigure 12 and Figure 13 As shown, it also includes a detection mechanism 6, which includes an L-shaped block 601 installed on the side of the U-shaped frame 304. A lower plate 604 is provided below the L-shaped block 601. A set of vertical rods 602 that pass through the L-shaped block 601 and are slidably connected to it are installed on the upper side of the lower plate 604. A limit block 603 is installed at the upper end of the vertical rods 602. The dust suction nozzle 503 limits the collection box 502.

[0068] like Figure 12 As shown, a telescopic rod 605 is installed at the upper center of the lower plate 604, and a pressing plate 606 is installed at the upper end of the telescopic rod 605. A detection spring 608 is installed between the pressing plate 606 and the lower plate 604. A pressure sensor 607 is installed on the lower side of the L-shaped block 601 directly below the pressing plate 606. The upward-moving conveying pipe 504 will compress the telescopic rod 605 and the detection spring 608. The rebound force of the detection spring 608 acts on the pressure sensor 607 through the pressing plate 606 and transmits the real-time pressure to the controller 1.

[0069] like Figure 2 and Figure 13 As shown, a roller 609 is installed on the lower side of the lower plate 604, and a trapezoidal block 610 is installed on the upper side of each square plate 318. The height of the upper surface of the multiple trapezoidal blocks 610 increases sequentially. When the roller 609 contacts the inclined surface of the trapezoidal block 610, the roller 609 will rise through the inclined surface, thereby squeezing the pressure sensor 607. Since the heights of the trapezoidal blocks 610 are different, the pressure on the pressure sensor 607 is also different. The pressure applied to the pressure sensor 607 by each trapezoidal block 610 can be matched with the model of its corresponding tool 317. When the pressure sensor 607 receives the corresponding pressure, it can distinguish the model of the tool 317 on the side of the notch of the limit ring 315. In addition, the upper surface area of ​​the trapezoidal block 610 is large, and when the roller 609 moves above the trapezoidal block 610, it will stabilize the pressure for a period of time.

[0070] In summary, when a certain type of cutting tool 317 is required, the rotation of the circular plate 302 will first cause all the trapezoidal blocks 610 to rotate. When the roller 609 contacts the inclined surface of the trapezoidal block 610, the roller 609 will rise through the inclined surface, causing the conveying pipe 504 to compress the telescopic rod 605 and the detection spring 608. The rebound force of the detection spring 608 will act on the pressure sensor 607 through the extrusion plate 606 and transmit the real-time pressure to the controller 1. The higher the upper surface of the trapezoidal block 610, the greater the pressure on the pressure sensor 607. When the pressure sensor 607 is subjected to pressure at a predetermined value and remains stable for a period of time, it means that the corresponding type of cutting tool 317 is on the side of the notch of the limit ring 315, and the rotation of the circular plate 302 can be stopped.

[0071] This application also discloses a method for using a five-axis, five-linkage machining center with a tool magazine, the steps of which are as follows:

[0072] S1. Tool Retrieval: The tool 317 to be used in the tool magazine mechanism 3 is installed on the chuck 219 of the machining mechanism 2. Specifically, the X-axis upper plate 209 moves around the X-axis, causing the tool magazine mechanism 3 to move so that the tool 317 to be used is directly below the chuck 219. Then, the A-axis electric cylinder 217 extends, causing the chuck 219 to descend and fix the tool holder of the tool 317. After that, it shortens, causing the tool 317 to be removed from the tool magazine mechanism 3.

[0073] S2. Workpiece machining: The workpiece is placed on the clamping seat 211 in the machining mechanism 2 for machining. Specifically, the X-axis upper plate 209 moves along the Y-axis to move the clamping seat 211 below the tool 317. The operator fixes the workpiece on the clamping seat 211. The A-axis electric cylinder 217 extends and the machining motor 218 runs to drive the tool 317 to rotate and machine the workpiece. At the same time, during the machining process, the moving Y-axis threaded seat 204 drives the workpiece to move along the Y-axis, the X-axis upper plate 209 drives the workpiece to move along the X-axis, the running C-axis motor 210 drives the workpiece to rotate around the C-axis, and the Z-axis side plate 216 drives the tool 317 to move around the Z-axis. With the assistance of the RTCP function, the workpiece moves synchronously on multiple axes while keeping the tool tip of the tool 317 stationary relative to the workpiece coordinate system.

[0074] S3. Tool Change: Specifically, the used tool 317 is placed into the corresponding stepped groove 303 and replaced with a different model of tool 317. Specifically, the X-axis upper plate 209 moves along the X-axis to align the empty stepped groove 303 with the tool 317. Then, the A-axis electric cylinder 217 shortens, causing the tool 317 to descend into the stepped groove 303. Then, the rotary motor 305 drives the circular plate 302 to rotate, allowing the used tool 317 to rotate away. At the same time, the corresponding guide wheel 314 and the arc plate 316 descend, allowing a set of clamps 311 to clamp the used tool 317. When the tool 317 to be used rotates to the side of the notch of the limit ring 315, the clamps 311 will be released, and then it will be re-fixed on the chuck 219, thus realizing tool change.

[0075] S4. Waste cleaning: After use, the tool 317 is placed in the stepped groove 303 and the cleaning mechanism 4 cleans the waste on its surface. Specifically, when the tool 317 is placed in the stepped groove 303 and the circular plate 302 rotates counterclockwise to move the tool 317 to the side of the notch of the limiting ring 315, the rotating circular plate 302 will also drive the rotating cylinder 401 corresponding to the tool 317 to move. The gear 402 on the moving rotating cylinder 401 meshes with the arc rack 403 and drives it to rotate. The rotating cylinder 401 cleans the waste on the surface of the tool 317 through the soft bristles 405.

[0076] S5. Waste Collection: During the cleaning process of the cleaning mechanism 4 cleaning the waste from the surface of the used tool 317, the waste collection mechanism 5 collects the waste. Specifically, the rotating circular plate 302 drives the gear 3 516 to rotate via gear two 515. The rotating gear three 516 drives the turntable 511 to rotate via two bevel teeth 517. The rotating turntable 511 pulls the piston 514 up and down via connecting rod 512 and extension rod 513. During the upward movement, the piston 514 draws air from the collection box 502 into the air cylinder 505 through the extension tube 506, thereby collecting the waste from each... A negative pressure is generated at the port of the suction nozzle 503. The suction nozzle 503 with negative pressure at the port can suck in the waste debris cleaned by the soft bristles 405 and transport it to the collection box 502 through the conveying pipe 504. At the same time, the dust screen is used to prevent the waste debris from entering the extension pipe 506 through the through hole. During the downward movement of the piston 514, the gas in the air cylinder 505 is discharged through the air outlet pipe 509. When the circular plate 302 stops rotating, the chip collection mechanism 5 stops working. When there is too much waste debris in the collection box 502, it can be unscrewed from the top cover 501, the waste debris can be poured out, and then it can be screwed back onto the top cover 501.

Therefore, the embodiments should be considered in all respects as exemplary and not restrictive.
