Description

Technical Field

[0001] The present invention relates to the technical field of machining centers, and particularly relates to a blanking mechanism of a machining center. Background Art

[0002] A machining center is a machine tool composed of mechanical equipment and a numerical control system, integrating various machining functions such as milling, drilling, tapping, boring, etc., and equipped with an automatic tool change system, capable of continuously completing the machining of multiple processes. The main components of a machining center include a machine tool body, a workbench, a tool system, a numerical control system, a cooling device, etc.

[0003] After retrieval, the invention patent with the Chinese patent number CN116214252A discloses a machining center. Compared with the prior art, the invention patent with the Chinese patent number CN116214252ACN214969281 hides the opened door inside the side plate and the door leaf, which not only shortens the required width of the door leaf but also does not affect the use of the external space of the machine frame.

[0004] However, in the actual use process of the above device, after the workpiece is processed, it is necessary for the staff to manually take out the workpiece. If the staff takes it out manually, the hand needs to reach into the machining center, and the efficiency is low. Moreover, there are many internal components in the machining center, and when taking out the workpiece, the hand and the workpiece are likely to come into contact with the internal components, resulting in hand injuries and workpiece damage. In addition, after the staff takes out the workpiece and places it in a fixed position, if the placement force is not well grasped, the workpiece is also likely to be damaged. Therefore, a blanking mechanism of a machining center is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages in the prior art that the workpiece is taken out manually, the efficiency is low, there are many internal components in the machining center, resulting in hand injuries and workpiece damage, etc., and after the staff takes out the workpiece and places it in a fixed position, if the placement force is not well grasped, the workpiece is also likely to be damaged, and to propose a blanking mechanism of a machining center.

[0006] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0007] A blanking mechanism for a machining center, including the machining center. A first support plate is installed on the side of the machining center. A blanking component for the machining center is arranged on the first support plate. The blanking component includes a first circular plate movably connected to the machining center, a square rod slidably arranged on the upper part of the first circular plate, and fixing plates symmetrically and slidably arranged on the side of the square rod. A rack is installed on the side of the first support plate. A gear is installed at the bottom of the first circular plate. The gear meshes with the rack. The first circular plate can slide to the opening of the machining center. While the first circular plate slides, it rotates by itself through the meshing of the gear and the rack. When the first circular plate slides and rotates by itself, the two fixing plates on the side of the square rod can move to the inside of the machining center. The two fixing plates move towards each other to clamp the workpiece, and then drive the workpiece to the outside of the machining center. The two fixing plates cancel the clamping of the workpiece through reverse movement to realize workpiece blanking, which improves the blanking efficiency and can also avoid potential safety hazards that may be brought by manual operation, such as workpiece dropping and hand injury;

[0008] A second support plate is installed on the machining center. A collecting component for the fixing plate is arranged on the second support plate. The collecting component includes a second circular plate rotatably connected to the outside of the machining center, a plurality of collecting boxes movably connected to the upper part of the second circular plate, and a movable plate slidably arranged inside the collecting box. The collecting box collects the workpieces dropped by the fixing plate. The second circular plate drives the plurality of collecting boxes to rotate for cyclic collection. When the collecting box collects the workpieces, the falling height of the fixing plate is always kept consistent by adjusting the up and down height of the movable plate, so as to avoid damage caused by impact during blanking.

[0009] The above technical solution further includes:

[0010] A first sliding groove is opened inside the first support plate. A first sliding block is slidably arranged inside the first sliding groove. A first servo motor is installed on the side of the first support plate. The output end of the first servo motor extending to the inside of the first sliding groove is installed with a first threaded rod. The first threaded rod is threadedly connected to the first sliding block. The acting force generated by the rotation of the first threaded rod can drive the first sliding block to move.

[0011] A rotating rod is rotatably connected to the inside of the first sliding block. The upper part of the rotating rod is fixedly connected to the first circular plate. The end of the rotating rod far from the first circular plate is fixedly connected to the gear. When the gear rotates, it drives the first circular plate to rotate through the rotating rod.

[0012] A first adjustment box is installed on the upper part of the first circular plate. A movable rod is slidably arranged inside the first adjustment box. A second servo motor is installed at the end of the first adjustment box. The output end of the second servo motor extending to the inside of the first adjustment box is equipped with a second threaded rod. The second threaded rod is threadedly connected to the movable rod. The force generated when the second threaded rod rotates can drive the movable rod to move.

[0013] One side of the square rod away from the fixed plate is fixedly connected to the movable rod. A second sliding groove is installed on the side of the square rod. Second sliding blocks are symmetrically and slidably arranged inside the second sliding groove. The second sliding blocks are fixedly connected to the fixed plate. The fixed plate can move towards each other along the second sliding groove through the second sliding blocks.

[0014] A third servo motor is installed inside the movable rod. The output end of the third servo motor is located inside the second sliding groove. A connecting rope is installed on the side of the second sliding block. One end of the connecting rope away from the second sliding block is fixedly connected to the output end of the third servo motor. Springs and telescopic rods are respectively installed on the side of the second sliding block. One ends of the springs and telescopic rods away from the second sliding block are fixedly connected to the inner wall of the second sliding groove. The rotation of the output shaft of the third servo motor can pull the second sliding block to move through the connecting rope.

[0015] A fourth servo motor is installed at the bottom of the second support plate. The output end of the fourth servo motor passes through the second support plate and is fixedly connected to the second circular plate. The fourth servo motor drives the second circular plate to rotate.

[0016] Square blocks are symmetrically installed at the bottom of the collection box. A plurality of square grooves are formed inside the second circular plate. The size of the opening of the square groove is adapted to the size of the square block. The square groove is movably connected to the square block. When the square block and the square groove are separated, the collection box can be directly taken out.

[0017] A plurality of second adjustment boxes are installed on the upper part of the second circular plate. A fifth servo motor is installed at the top of the second adjustment box. The output end of the fifth servo motor extending to the inside of the second adjustment box is equipped with a third threaded rod. The movable plate is slidably connected to the second adjustment box. The third threaded rod is threadedly connected to the movable plate. The fifth servo motor can drive the third threaded rod to reverse, thereby driving the movable plate to move up and down.

[0018] An opening groove is formed at the inner bottom of the collection box. The size of the opening of the opening groove is adapted to the size of the movable plate, which is convenient for the separation of the opening groove and the movable plate.

[0019] The present invention has the following beneficial effects:

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] As Figure 1 - Figure 8 shown, a blanking mechanism of a machining center proposed by the present invention includes a machining center 1. A first support plate 2 is installed on the side of the machining center 1. A blanking assembly for the machining center 1 is provided on the first support plate 2. The blanking assembly includes a first circular plate 10 movably connected to the machining center 1, a square rod 15 slidably arranged on the upper part of the first circular plate 10, and fixing plates 18 symmetrically and slidably arranged on the side of the square rod 15. A rack 9 is installed on the side of the first support plate 2. A gear 8 is installed at the bottom of the first circular plate 10. The gear 8 meshes with the rack 9. The first circular plate 10 can slide to the opening of the machining center 1. While the first circular plate 10 slides, it rotates self - clockwise through the meshing of the gear 8 and the rack 9. When the first circular plate 10 slides and rotates self - clockwise, the two fixing plates 18 on the side of the square rod 15 can move to the inside of the machining center 1. The two fixing plates 18 move towards each other to clamp the workpiece, and then drive the workpiece to the outside of the machining center 1. The two fixing plates 18 cancel the clamping of the workpiece through reverse movement to realize workpiece blanking, which improves the blanking efficiency and can also avoid potential safety hazards that may be brought by manual operation, such as workpiece dropping and hand injury;

[0034] A second support plate 23 is installed on the machining center 1. A collecting assembly for the fixing plate 18 is provided on the second support plate 23. The collecting assembly includes a second circular plate 25 rotatably connected to the outside of the machining center 1, a plurality of collecting boxes 29 movably connected to the upper part of the second circular plate 25, and a movable plate 26 slidably arranged inside the collecting box 29. The collecting box 29 collects the workpieces blanked by the fixing plate 18. The second circular plate 25 drives the plurality of collecting boxes 29 to rotate for cyclic collection. When the collecting box 29 collects the workpieces, the up - and - down height of the movable plate 26 is adjusted to keep the blanking height of the fixing plate 18 always the same, avoiding damage caused by impact during blanking.

[0035] A first sliding groove 3 is formed inside the first support plate 2. A first sliding block 4 is slidably arranged inside the first sliding groove 3. A first servo motor 5 is installed on the side of the first support plate 2. The output end of the first servo motor 5 extending to the inside of the first sliding groove 3 is provided with a first threaded rod 6. The first threaded rod 6 is threadedly connected to the first sliding block 4. The acting force generated by the rotation of the first threaded rod 6 can drive the first sliding block 4 to move.

[0036] A rotating rod 7 is rotatably connected to the inside of the first sliding block 4. The upper part of the rotating rod 7 is fixedly connected to the first circular plate 10. One end of the rotating rod 7 away from the first circular plate 10 is fixedly connected to the gear 8. When the gear 8 rotates, it drives the first circular plate 10 to rotate through the rotating rod 7.

[0037] A first adjusting box 11 is installed on the upper part of the first circular plate 10. A movable rod 12 is slidably arranged inside the first adjusting box 11. A second servo motor 13 is installed at the end of the first adjusting box 11. The output end of the second servo motor 13 extending to the inside of the first adjusting box 11 is provided with a second threaded rod 14. The second threaded rod 14 is threadedly connected to the movable rod 12. The acting force generated when the second threaded rod 14 rotates can drive the movable rod 12 to move.

[0038] One side of the square rod 15 away from the fixed plate 18 is fixedly connected to the movable rod 12. A second sliding groove 16 is installed on the side of the square rod 15. Second sliding blocks 17 are symmetrically and slidably arranged inside the second sliding groove 16. The second sliding blocks 17 are fixedly connected to the fixed plate 18. The fixed plate 18 can move oppositely along the second sliding groove 16 through the second sliding blocks 17.

[0039] A third servo motor 22 is installed inside the movable rod 12. The output end of the third servo motor 22 is located inside the second sliding groove 16. A connecting rope 19 is installed on the side of the second sliding block 17. One end of the connecting rope 19 away from the second sliding block 17 is fixedly connected to the output end of the third servo motor 22. Springs 20 and telescopic rods 21 are respectively installed on the side of the second sliding block 17. One ends of the springs 20 and telescopic rods 21 away from the second sliding block 17 are fixedly connected to the inner wall of the second sliding groove 16. The rotation of the output shaft of the third servo motor 22 can pull the second sliding block 17 to move through the connecting rope 19.

[0040] In this embodiment, when the machining of the workpiece in the machining center 1 is completed and blanking is required, the first servo motor 5 can be started. The first servo motor 5 drives the first threaded rod 6 to rotate. The force generated by the rotation of the first threaded rod 6 can drive the first sliding block 4 to move along the first sliding groove 3, and at the same time drive the first circular plate 10 to move until the first circular plate 10 is moved to the opening of the machining center 1. Since the gear 8 and the rack 9 are meshed with each other, when the first sliding block 4 drives the first circular plate 10 to move, it can drive the gear 8 to mesh on the rack 9, thereby driving the gear 8 to rotate on its own axis. At the same time, the first circular plate 10 is driven to rotate 180 degrees by the rotating rod 7. At this time, the two fixed plates 18 are facing the direction of the workpiece. Then, the second servo motor 13 can be started. The second servo motor 13 drives the second threaded rod 14 to rotate. The force generated when the second threaded rod 14 rotates can drive the movable rod 12 to move, so as to move the two fixed plates 18 to the inside of the machining center 1 and be located on both sides of the workpiece. Then, the third servo motor 22 can be started. The output shaft of the third servo motor 22 rotates to wind the connecting rope 19 around the output shaft of the third servo motor 22, thereby driving the two fixed plates 18 to move closer to each other along the second sliding groove 16 through the second sliding block 17 until the workpiece is clamped. At this time, the spring 20 and the telescopic rod 21 contract;

[0041] The second servo motor 13 drives the second threaded rod 14 to reverse, driving the workpiece on the fixed plate 18 to move to the outside of the machining center 1. Until the first servo motor 5 drives the first threaded rod 6 to reverse, the first circular plate 10 is reset, and at the same time drives the workpiece on the two fixed plates 18 to move above the collection box 29. Then, the third servo motor 22 is reversed. At this time, the fixed plate 18 is no longer driven by the first circular plate 10. The spring 20 and the telescopic rod 21 in the contracted state are reset, thereby driving the two fixed plates 18 to move away from each other. At this time, the workpiece is no longer clamped, and the workpiece can be placed inside the collection box 29 for blanking work. In this way, a series of actions such as clamping, moving, and placing can be quickly realized to grab the workpiece to the outside for blanking, improving the blanking efficiency, and also avoiding potential safety hazards that may be brought by manual operation, such as workpiece dropping and hand injury.

[0042] Embodiment 2

[0043] As Figure 1 - Figure 8 shown, on the basis of Embodiment 1, a fourth servo motor 24 is installed at the bottom of the second support plate 23. The output end of the fourth servo motor 24 passes through the second support plate 23 and is fixedly connected to the second circular plate 25. The fourth servo motor 24 drives the second circular plate 25 to rotate.

[0044] Square blocks 28 are symmetrically installed at the bottom of the collection box 29. A plurality of square grooves 27 are formed inside the second circular plate 25. The size of the opening of the square groove 27 is adapted to the size of the square block 28. The square groove 27 and the square block 28 are movably connected. When the square block 28 and the square groove 27 are separated, the collection box 29 can be directly taken out.

[0045] A plurality of second adjustment boxes 31 are installed on the upper part of the second circular plate 25. A fifth servo motor 32 is installed on the top of the second adjustment box 31. The output end of the fifth servo motor 32 extending to the inside of the second adjustment box 31 is installed with a third threaded rod 33. The movable plate 26 is slidably connected with the second adjustment box 31. The third threaded rod 33 is threadedly connected with the movable plate 26. The fifth servo motor 32 can drive the third threaded rod 33 to reverse, thereby driving the movable plate 26 to move up and down.

[0046] An opening groove 30 is formed at the inner bottom of the collection box 29. The size of the opening of the opening groove 30 is adapted to the size of the movable plate 26, which is convenient for the separation of the opening groove 30 and the movable plate 26.

[0047] In this embodiment, when using the collection box 29 to collect workpieces, the fifth servo motor 32 can be started at this time. The fifth servo motor 32 drives the third threaded rod 33 to rotate. The force generated when the third threaded rod 33 rotates drives the movable plate 26 to move up until the movable plate 26 is driven below the fixed plate 18, so that the movable plate 26 fits the workpiece. When the fixed plate 18 discharges materials, the workpiece can be directly placed on the movable plate 26. When it is necessary to discharge the next workpiece, the fifth servo motor 32 can drive the third threaded rod 33 to reverse at this time, thereby driving the movable plate 26 to move down, so that the height of the movable plate 26 moving down is the same as the thickness of the workpiece. At this time, the next workpiece can be steadily discharged on the previous workpiece. At this time, the discharging height is always the same, avoiding damage caused by impact during discharging. When the current collection box 29 is full of workpieces, the fourth servo motor 24 can be started. The fourth servo motor 24 drives the second circular plate 25 to rotate, thereby driving the next collection box 29 to the fixed plate 18 for collection work. And the collection box 29 can be directly lifted to separate the square block 28 and the square groove 27, and separate the opening groove 30 and the movable plate 26, then the collection box 29 can be directly taken out, and then the workpieces in the collection box 29 can be processed.

[0048] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
