[0002] Under the current background of the automation trend, many automation solutions have solved the problem of discharging small parts. However, there are not many discharging methods for long shaft rods, and most of them cannot solve the problems of collision damage and chip cutting obstruction. Moreover, when the output of automated products is insufficient, too many mechanisms are connected to the machine tool, making it inconvenient for personnel to operate on the machine tool and insert small-batch production. Therefore, an independent discharging machine outside the machine tool is needed. Summary of the Invention

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Refer to the attached drawings of the specification Figures 1-4, an independent external discharge machine for a machine tool in this embodiment includes a frame 12. Two fixed legs 14 are fixedly provided at the top of the frame 12. A cylinder linear rail fixing plate 18 is fixedly provided at the top of the fixed legs 14. A reciprocating linear rail 15 is fixedly provided at the top of the cylinder linear rail fixing plate 18. A reciprocating rodless cylinder 3 is provided on the reciprocating linear rail 15. A reciprocating cylinder 2 is fixedly provided at the top of the reciprocating rodless cylinder 3. An inclined material receiving groove 1 is fixedly provided at the top of the reciprocating cylinder 2. Inside the frame 12, a first material receiving groove 8, a second material receiving groove 9, a third material receiving groove 10, and a fourth material receiving groove 11 are successively arranged from top to bottom. The first material receiving groove 8 is arranged on one side of the fixed leg 14. Six first fixing plates 13 are arranged inside the frame 12. Two of the first fixing plates 13 distributed front and back are in a group. One end of the first material receiving groove 8, the second material receiving groove 9, the third material receiving groove 10, and the fourth material receiving groove 11 are all arranged inside the six first fixing plates 13. A bottom plate 21 is fixedly provided at the bottom end inside the frame 12. A material receiving mechanism 22 and a limiting mechanism 17 are provided on the top of the bottom plate 21. The limiting mechanism 17 is arranged on the top of the material receiving mechanism 22. The limiting mechanism 17 is arranged at the bottom of the fourth material receiving groove 11. A baffle 32 is arranged at one end inside the fourth material receiving groove 11. The baffle 32 extends out of the top end of the fourth material receiving groove 11. The outer end of the baffle 32 is in contact with the inner wall of the fourth material receiving groove 11. A first rotating rod 33 is penetrated inside the baffle 32. The first rotating rod 33 is arranged inside the fourth material receiving groove 11 and its two ends respectively extend out of the front and back ends of the fourth material receiving groove 11. The baffle 32 is fixedly connected with the first rotating rod 33. The two ends of the first rotating rod 33 are respectively movably connected with the front and back ends of the fourth material receiving groove 11 through bearings. A connecting rotating rod 34 is fixedly provided at the rear end of the first rotating rod 33.

[0030] Further, a second rotating rod 41 is arranged at one end inside the inclined material receiving groove 1. The two ends of the second rotating rod 41 respectively extend out of the front and back ends of the inclined material receiving groove 1 and are in contact with the inclined material receiving groove 1. A material receiving groove rotating plate 6 is fixedly provided at the outer end of the second rotating rod 41. The material receiving groove rotating plate 6 is arranged inside the inclined material receiving groove 1 and extends out of the top end of the inclined material receiving groove 1. The outer end of the material receiving groove rotating plate 6 is in contact with the inner wall of the inclined material receiving groove 1. Two torsion springs 42 are sleeved on both ends of the second rotating rod 41. The two ends of the torsion springs 42 are respectively fixedly connected with the outer end of the second rotating rod 41 and the outer end of the inclined material receiving groove 1. When the fixed ejector rod 7 enters the inclined material receiving groove 1 to push the material receiving groove rotating plate 6, the material receiving groove rotating plate 6 and the second rotating rod 41 rotate, so that the material receiving groove rotating plate 6 is opened. At the same time, the torsion springs 42 on the second rotating rod 41 rotate to generate elastic force. Then the workpiece in the inclined material receiving groove 1 falls. When the inclined material receiving groove 1 is separated from the ejector rod 7, the material receiving groove rotating plate 6 returns to its original state under the elastic force.

[0031] Further, a plurality of first grooves 43 are formed in the first fixing plate 13. A threaded rod 44 is disposed through the front and rear corresponding first grooves 43 in each group of first fixing plates 13. Nuts 4 are threadedly connected to both ends of the threaded rod 44. The nuts 4 are in contact with the outer end of the first fixing plate 13. A first rubber pad 5 is fixedly provided at the inner end of the first fixing plate 13. A plurality of second grooves 40 are formed in the first rubber pad 5. The second grooves 40 are disposed inside the first grooves 43. The outer ends of the plurality of threaded rods 44 are respectively in contact with the bottoms of the first material receiving groove 8, the second material receiving groove 9, the third material receiving groove 10, and the fourth material receiving groove 11. By adjusting the height of the threaded rod 44, the heights of both ends of the second material receiving groove 9, the third material receiving groove 10, and the fourth material receiving groove 11 are different, so that the angles of the second material receiving groove 9, the third material receiving groove 10, and the fourth material receiving groove 11 are changed.

[0032] Further, the other end of the first material receiving groove 8 is disposed at the top of the frame 12 and is provided with a second fixing plate 16. The second fixing plate 16 is fixedly disposed at the top of one side of the frame 12. A top rod 7 is fixedly provided at the rear end of the second fixing plate 16. The top rod 7 is disposed at the top of one end of the first material receiving groove 8. By the top rod 7 entering the inclined material receiving groove 1 to push the material receiving groove rotating plate 6, the material receiving groove rotating plate 6 is opened.

[0033] Further, a solenoid valve 20 is disposed on one side of the frame 12. The solenoid valve 20 is disposed between the second fixing plate 16 and the tray 25.

[0034] Further, the inclined material receiving groove 1 is disposed at the bottom of the machine tool spindle 19. The inclined material receiving groove 1 slides under the machine tool spindle 19, and the workpiece on the machine tool is pushed down by the rear push rod on the machine tool and falls into the inclined material receiving groove 1.

[0035] The implementation scenario is as follows: After the machine tool spindle 19 on the machine tool stops rotating, the pneumatic door of the machine tool opens. Driven by the reciprocating motion cylinder 2 and the reciprocating motion rodless cylinder 3, the inclined material receiving chute 1 slides into the position below the machine tool spindle 19. Then, the workpiece on the machine tool is pushed down by the rear pusher rod on the machine tool and falls onto the inclined material receiving chute 1. The signal end solenoid valve 20 causes the reciprocating motion cylinder 2 to stop moving downward. The new steel pipe is connected to the reciprocating motion rodless cylinder 3, and the reciprocating motion rodless cylinder 3 is fixed by the reciprocating linear guide 15, the cylinder linear guide fixing plate 18, and the fixed leg 14. The reciprocating motion rodless cylinder 3 moves downward to the stroke. Then, the fixed ejector rod 7 enters the inclined material receiving chute 1 to push the material receiving chute rotating plate 6, causing the material receiving chute rotating plate 6 and the second rotating rod 41 to rotate, so that the material receiving chute rotating plate 6 is opened. At the same time, the torsion spring 42 on the second rotating rod 41 rotates to generate elastic force. Then, the workpiece in the inclined material receiving chute 1 rolls into the first material receiving chute 8, and then falls into the fourth material receiving chute 11 along the second material receiving chute 9 and the third material receiving chute 10. While the workpiece is rolling downward, the receiving angles of the second material receiving chute 9, the third material receiving chute 10, and the fourth material receiving chute 11 can be adjusted to adjust the rolling speed of the workpiece. The specific steps are as follows: Loosen the nut 4 on the threaded rod 44, and then move the threaded rod 44 up and down along the first groove 43 to an appropriate height, and then tighten the nut 4 to fix the threaded rod 44 to the first fixing plate 13. At this time, the heights of the threaded rods 44 on two adjacent groups of first fixing plates 13 are different, so the heights at both ends of the second material receiving chute 9, the third material receiving chute 10, and the fourth material receiving chute 11 are different, and the angles of the second material receiving chute 9, the third material receiving chute 10, and the fourth material receiving chute 11 change. At the same time, the first rubber pad 5 on the first fixing plate 13 contacts the second material receiving chute 9, the third material receiving chute 10, and the fourth material receiving chute 11, increasing the friction force received by the second material receiving chute 9, the third material receiving chute 10, and the fourth material receiving chute 11, thereby improving the installation stability of the second material receiving chute 9, the third material receiving chute 10, and the fourth material receiving chute 11. The entire mechanism of the present invention is independent of the machine tool, and only a few circuit signals are connected to the machine tool, without other structural connections, which is convenient for rapid movement and production adjustment. Also, because the entire material receiving process only enters when the machine tool is stopped and the mechanism exits when the machine tool is working, it greatly avoids the interference of uncertain factors such as iron filings to the automation stability, reasonably stores and collects materials, avoids collisions, and minimizes the time required for personnel to cooperate in boxing.

[0036] Refer to the attached drawings of the specification Figure 1 and 5-9, An independent external material discharging machine for a machine tool in this embodiment further includes a material receiving mechanism 22. The material receiving mechanism 22 includes a slide plate 24. The slide plate 24 is arranged inside the frame 12 and extends out of one side of the frame 12. The slide plate 24 is arranged at the top of the bottom plate 21 and is connected to the bottom plate 21 through a slide rail. A second rubber pad 23 is fixedly arranged at the top of the slide plate 24. A tray 25 is arranged on the top of the second rubber pad 23. A rack 26 is fixedly arranged at the rear side of the top of the slide plate 24. The rack 26 is arranged at the rear end of the second rubber pad 23. A motor 28 is fixedly arranged at the rear side of the frame 12 through a bracket. A gear 27 and a first pulley 29 are fixedly arranged on the output shaft of the motor 28. The first pulley 29 is fixedly arranged at the front end of the gear 27. The gear 27 meshes with the top of the rack 26. The first pulley 29 is arranged on the top of the second rubber pad 23. A second pulley 30 is arranged on the top of the first pulley 29. The second pulley 30 is connected to the first pulley 29 through a belt 31. The connecting rotating rod 34 is fixedly connected to the front end of the second pulley 30.

[0037] Furthermore, the limiting mechanism 17 includes a fixed rod 36. The fixed rod 36 is arranged inside the frame 12 and is fixedly connected to one side inside the frame 12 at both ends. Two movable sleeves 37 are sleeved on the fixed rod 36. The movable sleeves 37 are in contact with the fixed rod 36. Limiting plates 38 are fixedly arranged at the bottom ends of the two movable sleeves 37. The bottom ends of the limiting plates 38 are in contact with the top of the second rubber pad 23. The two limiting plates 38 are respectively in contact with the front and rear ends of the tray 25. The limiting plates 38 are arranged in front of the first pulley 29, the second pulley 30 and the belt 31. A fastening bolt 39 is arranged through the top end of the movable sleeve 37. One end of the fastening bolt 39 is in contact with the top end of the fixed rod 36. The fastening bolt 39 is threadedly connected to the movable sleeve 37. Adjust the positions of the two limiting plates 38 to limit the tray 25 and prevent the front and rear positions of the tray 25 from shifting.

[0038] Furthermore, two limiting baffles 35 are arranged at one end of the fourth material receiving groove 11. Both of the two limiting baffles 35 are connected to the fourth material receiving groove 11 through spring hinges to block the workpieces in the fourth material receiving groove 11.

[0039] The specific implementation scenario is as follows: After the machine tool has been processing for a period of time, a certain number of workpieces are stored in the fourth material receiving groove 11. Then, the pallet 25 is placed on the sliding plate 24. The second rubber pad 23 on the sliding plate 24 contacts the pallet 25 to increase the frictional force received by the pallet 25 and improve the stability of the pallet 25. Then, the two limiting plates 38 are moved towards the direction close to the pallet 25, so that the movable sleeves 37 on the limiting plates 38 move along the fixed rods 36. As a result, the two limiting plates 38 contact the pallet 25. Then, the fastening bolts 39 are tightened to fix the limiting plates 38. At this time, the limiting plates 38 limit the pallet 25 to prevent the pallet 25 from shifting in the front and back positions. Then, the motor 28 is started. The motor 28 drives the gear 27 to rotate, causing the rack 26 to move to the left. As a result, the sliding plate 24 is driven to move to the left along the slide rail, and then the pallet 25 is driven to move to the left. At the same time, the gear 27 drives the first pulley 29 to rotate, so as to drive the second pulley 30 to rotate through the belt 31. Then, the connecting rotating rod 34 and the first rotating rod 33 are driven to rotate. The first rotating rod 33 drives the material blocking plate 32 to rotate. When the material blocking plate 32 rotates one circle, the workpiece near the material blocking plate 32 on the fourth material receiving groove 11 can be toggled. The workpiece pushes open the limiting baffle 35 of the inclined material receiving groove 1 through the spring hinge and rotates to open. Then, the workpiece falls onto the lower pallet 25. Then, the limiting baffle 35 closes under the elastic force of the spring hinge. Then, the material blocking plate 32 rotates one circle again to toggle the next workpiece onto the moving pallet 25 below. At this time, this workpiece on the pallet 25 is on the right side of the workpiece that fell onto the pallet 25 last time. Thus, the sequentially arranged falling workpieces are realized, avoiding the workpieces falling at one place and colliding with each other and being damaged. When the sliding plate 24 moves out of the machine frame 12, a conveyor can be docked at the bottom plate 21 of the machine frame 12, so that the pallet 25 moves onto the conveyor and is transported to the next working station.

[0040] Although the present invention has been described in detail above with general descriptions and specific embodiments, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
