Description

Technical Field

[0001] This invention relates to the field of machining center technology, and more specifically, to a high-precision five-axis linkage machining center with a swing head. Background Technology

[0002] In manufacturing, especially in the field of precision machining, high-precision five-axis machining centers with oscillating heads play a crucial role. Traditional three-axis or four-axis machining centers have certain limitations when handling complex curved surfaces and multi-angle workpieces, while five-axis machining centers offer greater freedom and can handle complex curved surface parts with multi-axis linkage in a more flexible manner. This is particularly important for applications in aerospace, automotive manufacturing, mold making, and other fields that require extremely high workpiece precision and surface quality.

[0003] Chinese patent application 202111360270.X discloses a device, method, and storage medium for a high-precision five-axis linkage machining center. The center includes a base, a support on top of the base, a controller on one side of the support, a Z-axis drive device on one side of the support, a servo spindle at the output end of the Z-axis drive device, and a cutting tool at the output end of the servo spindle. A Y-axis drive device is located on top of the base, a moving stage at the output end of the Y-axis drive device, an X-axis drive device on top of the moving stage, a sliding frame at the output end of the X-axis drive device, and a first rotary motor on one side of the sliding frame. The first rotary motor's output end is a rotating stage. This invention not only enables five-axis linkage machining of workpieces but also improves the clamping accuracy and effect of the workpieces, ensuring that the workpieces do not detach or fall during rotation, thus guaranteeing machining results and improving machining precision.

[0004] Although this type of machining center can perform five-axis simultaneous machining of workpieces and improve the clamping accuracy and effect, it is not convenient to clean the unloading trough. Moreover, the existing technology usually uses a blower to clean it, and the surface of the unloading trough with adhering debris is still prone to leaving debris. The debris can easily drift into the inside of the equipment, affecting the service life and accuracy of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision five-axis linkage machining center with a swing head.

[0006] To address the aforementioned technical problems, this invention provides a high-precision five-axis linkage machining center with a swivel head, comprising a machining housing and a machining table installed inside the machining housing, and further comprising:

[0007] The material feeding trough is located at the bottom of the processing table. The two sides of the inner wall of the material feeding trough are fixed with material dropping guide plates, and the debris falls into the bottom of the material feeding trough from the material dropping hole between the two material dropping guide plates.

[0008] The cleaning unit includes a lateral moving mechanism and an inner sleeve mounted on the lateral moving mechanism, as well as a driving mechanism mounted on the inner wall of the feeding trough. An outer sleeve is fitted over the inner sleeve. A rotating assembly is located at the top of the inner sleeve to control the rotation angle of the inner sleeve. A first motor is installed inside the inner sleeve, and a turntable is mounted at the bottom of the first motor. Brush strips are mounted at the bottom of the turntable.

[0009] When the end of the drive mechanism is inserted into the side wall of the inner sleeve, it can drive the inner sleeve to rotate around the central axis of the transverse moving mechanism.

[0010] Furthermore, the lateral movement mechanism includes a second motor and a lead screw mounted on one end of the second motor. The inner sleeve has a screw hole, which is fitted onto the lead screw. The second motor is used to drive the inner sleeve to move left and right along the lead screw.

[0011] Furthermore, the drive mechanism includes a third motor and a rotating sleeve mounted on one end of the third motor. The rotating sleeve and the lead screw are located on the same axis. One end of the rotating sleeve is provided with a circular groove, and the other end of the lead screw is installed in the circular groove.

[0012] Furthermore, a protrusion is fixed at one end of the rotating sleeve, and a groove is provided on the side wall of the inner sleeve. When the groove on the inner sleeve moves to the position of the protrusion, the third motor is used to drive the outer sleeve to rotate around the lead screw.

[0013] Furthermore, the rotating assembly includes a first through hole formed on the inner sleeve and a ratchet installed in the first through hole. The screw hole is located at the center of the ratchet. The inner surface of the first through hole is hinged with ratchet teeth. The ratchet and the ratchet teeth cooperate with each other. The top of the inner sleeve is semi-circular.

[0014] Furthermore, the inner sleeve has a first annular groove on both sides, the ratchet has a second annular groove on its surface, and the inner walls of the first and second annular grooves have a third annular groove. A first retaining ring is installed inside the first annular groove, a second retaining ring is installed inside the second annular groove, and a third retaining ring is fixed to the upper surfaces of the first and second retaining rings. The third retaining ring is installed in the third annular groove, and the first and second retaining rings are fixedly connected by a connecting rod.

[0015] Furthermore, the material discharge trough has plate holes on both sides, and the two ends of the material discharge plate pass through the plate holes. The top of the material discharge plate has a material discharge trough, and the middle of the material discharge trough has two mirrored inclined surfaces, with the connection point of the two inclined surfaces located below the material discharge hole. The bottom of the material discharge trough has a material discharge hole, and a filter screen is provided on the material discharge hole.

[0016] Furthermore, a cleaning rod is installed at the top of the material discharge chute, a movable plate is fixed at the middle of the top of the cleaning rod, a first support rod is fixed at the bottom of one side of the movable plate, an inclined plate is fixed on the other side of the movable plate, and a second support rod is fixed above the inclined plate.

[0017] Furthermore, one side of the inner sleeve has several mounting grooves, and a spring is installed inside each groove. One end of the spring is fixed with a protrusion, the end of which is semi-circular. One side of the outer sleeve has a circular hole into which the protrusion can be inserted.

[0018] When the outer sleeve moves toward the inclined plate, the outer sleeve can move upward along the inclined plate. When the round hole on the outer sleeve moves to the end of the second support rod, the second support rod can be inserted into the round hole.

[0019] Furthermore, a cutting head is installed inside the processing shell, and a fume hood is fitted on the outer surface of the cutting head. A corrugated pipe is connected to one side of the fume hood, and a gas collecting pipe is connected to one end of the corrugated pipe. An exhaust pipe is fixed to one end of the gas collecting pipe, and the exhaust pipe is installed in the material feeding trough and located at the bottom of the inclined surface.

[0020] The beneficial effects of this invention are:

[0021] 1. By installing an inner sleeve on the transverse moving mechanism, the inner sleeve can clean the material guide plate and inclined surface along the transverse moving mechanism. During cleaning, the brush strip on the turntable is driven to rotate by starting the first motor. The bottom of the brush strip is located outside the outer sleeve. The rotation of the brush strip is used to clean the material guide plate and inclined surface, sweeping the debris and slag adhering to the surface into the material discharge hole.

[0022] 2. By installing a cleaning rod at the top of the discharge chute, the moving plate can be pushed to move left and right when the outer sleeve or inner sleeve moves. At the same time, when the outer sleeve pushes the moving plate to the side wall of the discharge chute near the first motor, the first support rod can abut against the side wall of the discharge chute, leaving a certain distance between the moving plate and the side wall of the discharge chute, allowing the outer sleeve to be inserted between the moving plate and the side wall of the discharge chute. The moving plate is then pushed to the other side again, and the surface of the filter screen is cleaned by the cleaning plate at the bottom, while preventing blockage of the discharge hole by large debris.

[0040] like Figure 1-10As shown, a high-precision five-axis linkage machining center with a swing head according to the present invention includes a machining housing 1 and a machining table 11 installed inside the machining housing 1. It also includes: a feeding trough 2, which is located at the bottom of the machining table 11. The feeding trough 2 has two feeding guide plates 21 fixed on both sides of the inner wall of the feeding trough 2. The debris falls into the bottom of the feeding trough 2 from the feeding hole 22 between the two feeding guide plates 21. The feeding trough 2 has plate holes 23 on both sides. The two ends of the feeding plate 28 pass through the plate holes 23. The feeding trough 24 is provided at the top of the feeding plate 28. The feeding trough 24 has two mirrored inclined surfaces 25 in the middle. The connection between the two inclined surfaces 25 is located below the feeding hole 22. The feeding hole 26 is provided at the bottom of the feeding trough 24. A filter screen 261 is provided on the feeding hole 26.

[0041] The material discharge trough 2 collects the debris and coolant generated from the parts processed on the processing table 11. Two guide plates 21 fixed on the inner side wall of the material discharge trough 2 are set in a mirror image and are inclined. The debris can fall from the middle discharge hole 22 along the guide plate 21 into the material discharge plate body 28. After being filtered by the filter screen 261, the coolant can fall from the discharge hole 26 into the bottom of the material discharge plate for centralized collection.

[0042] The cleaning unit 3 includes a transverse moving mechanism 31 and an inner sleeve 32 mounted on the transverse moving mechanism 31, as well as a drive mechanism 33 mounted on the inner side wall of the feeding trough 2. An outer sleeve 34 is fitted around the inner sleeve 32. A rotating component 35 is provided on the top of the inner sleeve 32. The rotating component 35 is used to control the rotation angle of the inner sleeve 32. A first motor 321 is installed inside the inner sleeve 32. A turntable 322 is installed at the bottom of the first motor 321. A brush strip 323 is installed at the bottom of the turntable 322. When the end of the drive mechanism 33 is inserted into the side wall of the inner sleeve 32, it can drive the inner sleeve 32 to rotate around the central axis of the transverse moving mechanism 31.

[0043] By installing an inner sleeve 32 on the transverse moving mechanism 31, the inner sleeve 32 can clean the surface of the material guide plate 21 and the inclined surface 25 along the transverse moving mechanism 31. During cleaning, the brush strip 323 on the turntable 322 is driven to rotate by starting the first motor 321. The bottom of the brush strip 323 is located outside the outer sleeve 34. The rotation of the brush strip 323 is used to clean the surface of the material guide plate 21 and the inclined surface 25, and sweep the debris and slag adhering to the surface into the material discharge hole 22.

[0044] The lateral movement mechanism 31 includes a second motor 311 and a lead screw 312 installed at one end of the second motor 311. A screw hole 324 is provided on the inner sleeve 32, and the screw hole 324 is sleeved on the lead screw 312. The second motor 311 is used to drive the inner sleeve 32 to move left and right along the lead screw 312.

[0045] The lateral movement mechanism 31 is used to drive the inner sleeve 32 to move left and right in the feeding trough 2. By starting the second motor 311, the lead screw 312 is driven to rotate. The screw hole 324 on the outer sleeve 34 cooperates with the lead screw 312, allowing the outer sleeve 34 to move left and right along the lead screw 312.

[0046] The drive mechanism 33 includes a third motor 331 and a rotating sleeve 332 mounted on one end of the third motor 331. The rotating sleeve 332 and the lead screw 312 are located on the same axis. One end of the rotating sleeve 332 is provided with a circular groove 333. The other end of the lead screw 312 is installed in the circular groove 333. One end of the rotating sleeve 332 is fixed with a protrusion 334. A groove 335 is provided on the side wall of the inner sleeve 32. When the groove 335 on the inner sleeve 32 moves to the position of the protrusion 334, the third motor 331 is used to drive the outer sleeve 34 to rotate around the lead screw 312.

[0047] The inner sleeve 32 is driven to rotate by the drive mechanism 33. In use, the end of the lead screw 312 is inserted into the circular groove 333, and the other end of the lead screw 312 is supported by the rotating sleeve 332. At the same time, the rotation of the lead screw 312 does not affect the rotation of the circular groove 333. When the groove 335 on the inner sleeve 32 moves to the position of the protrusion 334, the protrusion is inserted into the groove 335, and the third motor 331 is started. The third motor 331 drives the outer sleeve 34 to rotate around the lead screw 312, which can rotate the inner sleeve 32 to different angles to clean the area above the material guide plate 21, further improving the cleaning effect.

[0048] The rotating assembly 35 includes a first through hole 351 formed on the inner sleeve 32 and a ratchet 352 installed in the first through hole 351. A screw hole 324 is located at the center of the ratchet 352. A ratchet tooth 353 is hinged to the inner surface of the first through hole 351. The ratchet 352 and the ratchet tooth 353 cooperate with each other. The top of the inner sleeve 32 is semi-circular. A first annular groove 354 is formed on both sides of the inner sleeve 32. A second annular groove 356 is formed on the surface of the ratchet 352. A third annular groove 357 is formed on the inner sidewall of the first annular groove 354 and the second annular groove 356. A first retaining ring 358 is installed inside the first annular groove 354. A second retaining ring 359 is installed inside the second annular groove 356. A third retaining ring 3510 is fixed on the upper surface of the first retaining ring 358 and the second retaining ring 359. The third retaining ring 3510 is installed in the third annular groove 357. The first retaining ring 358 and the second retaining ring 359 are fixedly connected by a connecting rod 355.

[0049] Since the inner sleeve 32 is difficult to fix after rotating a certain angle, the rotation angle of the inner sleeve 32 is controlled by the rotating component 35. When the second motor 311 rotates, it drives the inner sleeve 32 to rotate clockwise. When the inner sleeve 32 rotates, the ratchet 353 rotates at the same time. When the inner sleeve 32 rotates to the position of the corresponding material guide plate 21, the ratchet 352 and the ratchet 353 cooperate and fix it, fixing the inner sleeve 32 in the corresponding position. At this time, the lead screw 312 is driven again to drive the inner sleeve 32 to disengage from the protrusion 334 for movement and cleaning.

[0050] By installing the first retaining ring 358 in the first annular groove 354, and engaging the third retaining ring 3510 on the first retaining ring 358 in the third annular groove 357, the first retaining ring 358 is prevented from dislodging from the first annular groove 354 while allowing it to rotate along the first annular groove 354. Simultaneously, the second retaining ring 359 is installed in the second annular groove 356, and engaging the third retaining ring 3510 on the second retaining ring 359 in the third annular groove 357. This prevents the first retaining ring 358 from dislodging from the first annular groove 354 while allowing it to rotate along the first annular groove 354. The first retaining ring 358 and the second retaining ring 359 are fixed together by the connecting rod 355. The ratchet 352 is fixed in the first through hole 351, preventing it from dislodging from the first through hole 351. Furthermore, the rotation of the inner sleeve 32 to adjust the angle does not affect the left and right movement of the ratchet 352 along the lead screw 312.

[0051] A cleaning rod 27 is installed at the top of the inside of the material discharge chute 24. A movable plate 271 is fixed at the middle position of the top of the cleaning rod 27. A first support rod 272 is fixed at the bottom of one side of the movable plate 271. An inclined plate 273 is fixed on the other side of the movable plate 271. A second support rod 274 is fixed above the inclined plate 273.

[0052] A cleaning rod 27 is installed on the top of the discharge chute 24. The cleaning rod 27 has straight rods at both ends and a slanted rod in the middle, which is the same as the inclined plane 25. A moving plate 271 is fixed above the slanted rod. The bottom of the moving plate 271 is located inside the discharge hole 22 and can move left and right along the discharge hole 22. When the outer sleeve 34 or the inner sleeve 32 moves, it can push the moving plate 271 to move left and right. At the same time, when the outer sleeve 34 pushes the moving plate 271 to the side wall of the discharge chute 2 near the first motor 321, the first support rod 272 can abut against the side wall of the discharge chute 2, leaving a certain distance between the moving plate 271 and the side wall of the discharge chute 2, so that the outer sleeve 34 can be inserted between the moving plate 271 and the side wall of the discharge chute 2. The moving plate 271 is pushed to the other side again, and the surface of the filter screen 261 is cleaned by the cleaning plate at the bottom, while preventing the discharge hole 22 from being blocked by large debris.

[0053] The inner sleeve 32 has several mounting slots 36 on one side, and a spring 361 is installed inside the mounting slot 36. One end of the spring 361 is fixed with a protrusion 362, and the end of the protrusion 362 is semi-circular. The outer sleeve 34 has a round hole 37 on one side, and the end of the protrusion 362 can be inserted into the round hole 37. When the outer sleeve 34 moves toward the inclined plate 273, the outer sleeve 34 can move upward along the inclined plate 273. When the round hole 37 on the outer sleeve 34 moves to the end of the second support rod 274, the second support rod 274 can be inserted into the round hole 37.

[0054] The outer sleeve 34 is fitted onto the inner sleeve 32. The outer sleeve 34 can move upward along the inner wall of the inner sleeve 32. When the outer sleeve 34 moves to one side of the inclined plate 273, it can move upward along the inclined plate 273. When it moves to a certain position, the protrusion 362 of the inner sleeve 32 can be inserted into the round hole 37 on the outer sleeve 34 to fix the position of the outer sleeve 34. At the same time, more of the bottom brush is exposed, which can clean the material guide plate 21 more thoroughly when rotating. When it is necessary to lower the outer sleeve 34 again, the outer sleeve 34 is moved to one side of the inclined plate 273 again. When it moves to the second support rod 274, the second support rod 274 is inserted into the round hole 37, and the protrusion 362 is squeezed into the mounting groove 36 again. At the same time, the outer sleeve 34 falls down to the protrusion 362 at the bottom.

[0055] Inside the processing housing 1, a cutting head 12 is installed. A fume hood 13 is fitted on the outer surface of the cutting head 12. A corrugated pipe 14 is connected to one side of the fume hood 13. A gas collecting pipe 15 is connected to one end of the corrugated pipe 14. An exhaust pipe 16 is fixed to one end of the gas collecting pipe 15. The exhaust pipe 16 is installed in the feeding trough 2 and is located at the bottom of the inclined surface 25.

[0056] By installing a fume hood 13 on the chip head, the fume hood 13 can be used to collect the smoke and dust generated when no coolant is added. The smoke and dust are drawn into the bellows 14 and introduced into the gas collection pipe 15 through the bellows 14. The gas is then discharged through the gas collection pipe 15 into the bottom of the discharge trough 2, which contains a mixture of chips and coolant. The gas directly filters out metal and harmful gases in the air by contacting the liquid. It is located below the inclined surface 25, which can block some of the gas and allow it to be discharged directly from the discharge hole 26.

[0057] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
