Description

Technical Field

[0001] The present invention relates to the technical field of gear processing, and more particularly to a micro gear processing device. Background Art

[0002] Gears are a commonly used mechanical transmission element, widely used in various mechanical equipment. At present, according to the design requirements of the gear, suitable gear materials can be selected. Common materials include steel, cast iron, copper alloy, etc., and then suitable gear cutting tools such as gear milling cutters and gear hobs are selected for cutting. Common cutting methods include milling, turning, grinding, etc. Micro gears refer to smaller gears. Micro gears are made by slotting cylindrical workpieces.

[0003] When processing micro gears, the finger milling cutter is generally moved from one end of the workpiece to the other end of the workpiece, so as to process multiple tooth grooves on the arc-shaped surface of the workpiece, thereby completing the processing of the micro gear. When the finger milling cutter is processing the tooth groove, one end of the tooth groove is closed, so the waste chips generated by the finger milling cutter in the process of processing the tooth groove are not easy to be discharged from the tooth groove, and the depth of the tooth groove is continuously increased during the downward processing of the finger milling cutter, which increases the difficulty of waste chip discharge. In the overall processing process, more waste chips are accumulated, so it is easy to generate more burrs in the tooth groove, thereby reducing the processing quality of the micro gear.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] A micro gear processing device, such as Figure 1-Figure 6As shown, it includes a frame 1, on which a loading mechanism, a slotting mechanism and a unloading mechanism are sequentially arranged;

[0030] The feeding mechanism is used for manual loading, clamping the workpiece and transporting the workpiece to the slotting mechanism, so that the workpiece can rotate and move up and down in coordination with the slotting mechanism;

[0031] A slotting mechanism, used for slotting the workpiece from the upper and lower sides of the workpiece;

[0032] The unloading mechanism is arranged on the side opposite to the slotting mechanism and is used to transport the processed workpiece.

[0033] Manual loading can be performed through the loading mechanism. The staff clamps the workpiece, and finally the workpiece can be moved to the slotting mechanism to facilitate continuous processing of the workpiece. The slotting mechanism slots the workpiece from both sides of the workpiece. During operation, the slotting mechanism can first process the workpiece from the bottom, and then completely process the workpiece from the top. This method can change the one-time slotting of the workpiece to the second slotting, making it easier to discharge the waste chips generated during the slotting process along the slotting mechanism, shortening the path for the waste chips to be discharged, thereby reducing the defects of the workpiece during the processing and improving the processing quality of the workpiece. After the slotting mechanism completes the processing, the unloading mechanism can remove and collect the workpiece.

[0034] like Figure 3-Figure 5 As shown, the slotting mechanism includes a first movable member and a second movable member, both of which are arranged on one side of the feeding mechanism, a mounting frame 2 is slidably connected to the frame 1, the first movable member includes a motor 3, the output end of the motor 3 passes through the mounting frame 2 and is fixedly connected to a support rod 4, the upper half of the support rod 4 is provided with a thread 5, the support rod 4 is provided with a thread 5 and is threadedly connected to a mounting plate 6, the first slotting member is arranged on the mounting plate 6, the second movable member includes a motor 2 7, the output end of the motor 2 7 passes through the mounting frame 2 and is fixedly connected to a support rod 2 8, the lower half of the support rod 2 8 is provided with a thread 2 9, the support rod 2 8 is provided with a thread 2 9 and is threadedly connected to a mounting plate 2 10, the second slotting member is arranged on the mounting plate 2 10, the lower half of the support rod 4 is slidably connected to the mounting plate 2 10, and the upper half of the support rod 2 8 is slidably connected to the mounting plate 6. The first moving member is connected with a first slotted member, the second moving member is connected with a second slotted member, the first slotted member and the second slotted member are arranged opposite to each other up and down, the first slotted member is arranged at the top of the workpiece, and the second slotted member is arranged at the bottom of the workpiece.

[0035] In the above technical solution, the first moving part and the second moving part are similar in arrangement, and only the position of the thread 15 on the support rod 14 and the position of the thread 29 on the support rod 28 are different, which saves the improvement cost. When the first slotted part needs to be moved, the motor 13 is started to drive the support rod 14 to rotate. Since the mounting plate 16 can abut against the mounting frame 2, the support rod 14 can drive the mounting plate 16 to move up and down, thereby driving the first slotted part on the mounting plate 16 to move. Since the support rod 14 is only provided with the thread 15 in its upper half, the mounting plate 16 can only move in the part with the thread 15, that is, the workpiece is processed from the top. Similarly, the motor 27 can drive the mounting plate 210 to move on the threaded rod 2, so that the second slotted part can process the workpiece from the bottom. The support rod 14 and the support rod 28 both pass through the mounting plate 16 and the mounting plate 210, which can improve the stability of the mounting plate 16 and the mounting plate 210 moving up and down, and reduce the shaking of the two and affect the processing quality.

[0036] like Figure 4-Figure 5 As shown, the first slotting member includes a motor three 11 and a finger-shaped milling cutter 12. The motor three 11 is fixedly connected to the top surface of the mounting plate 6, and the finger-shaped milling cutter 12 is arranged on the bottom surface of the mounting plate 6. The finger-shaped milling cutter 12 is fixedly connected to the output end of the motor three 11. When the motor three 11 is started, it can drive the finger-shaped milling cutter 12 to rotate, so that the finger-shaped milling cutter 12 rotates and cuts on the surface of the workpiece. The second slotting member includes a motor 4 13 and a finger-shaped milling cutter 2 14. The motor 4 13 is fixedly connected to the top surface of the mounting plate 2 10. The output end of the motor 4 13 passes through the mounting plate 2 10 and is fixedly connected to a driving gear 15. A driven gear 16 is meshed at the driving gear 15. A rotating shaft 17 is fixedly connected to the center of the driven gear 16. The rotating shaft 17 passes through the mounting plate 2 10 and is fixedly connected to the finger-shaped milling cutter 2 14. When processing the workpiece from the bottom, it is difficult for the motor 4 13 to be directly inserted between the workpiece and the feeding mechanism. Therefore, the motor 4 13 is used to drive the driving gear 15 to rotate, and the driving gear 15 drives the driven gear 16 to rotate to drive the finger-shaped milling cutter 2 14 to rotate, so that the finger-shaped milling cutter 2 14 can process the workpiece from the bottom.

[0037] like Figure 3 and Figure 4As shown, the loading mechanism includes a loading tray 18, a driving motor 19 is fixedly connected to the frame 1, the output end of the driving motor 19 is fixedly connected to the center of the loading tray 18, a plurality of loading ports 20 are provided on the loading tray 18, a receiving block 21 is slidably connected to the loading port 20, and a plurality of pneumatic clamping blocks 22 are slidably connected to the upper surface of the receiving block 21. The loading tray 18 is arranged at the center of the frame 1, and can be rotated by the driving motor 19 to transport the workpiece to the first slotted part, the second slotted part and the unloading mechanism. There are four loading ports 20, which are evenly distributed on the loading tray 18. The workpiece can be clamped by the pneumatic clamping block 22 to facilitate the transportation of the workpiece. During the rotation of the loading tray 18, the workpiece can be rotated and transported together with the loading tray 18.

[0038] Furthermore, the feeding mechanism also includes a mounting groove 23 opened at the bottom of the receiving block 21, the cross-section of the mounting groove 23 is a polygon, a motor 5 24 is fixedly connected in the frame 1, the motor 5 24 is arranged on a side close to the mounting frame 2, the output end of the motor 5 24 is fixedly connected to a support plate 25, the top of the support plate 25 is fixedly connected to a clamping block 26 with the same shape as the mounting groove 23, a receiving plate 27 is slidably connected in the frame 1, a cylinder 1 28 is fixedly connected to the bottom of the frame 1, the piston end of the cylinder 1 28 is fixedly connected to the bottom of the receiving plate 27, when the workpiece needs to be processed, the feeding tray 18 can drive the workpiece to a side close to the first slotted part and the second slotted part, so that the cylinder 1 28 is then started, and the cylinder 1 28 can push the motor to move upward, so that the clamping block 26 is inserted into the mounting groove 23, and during the processing, the motor 5 24 can drive the receiving block 21 to rotate, so that the workpiece can rotate along with the processing action, thereby realizing the linkage effect between the workpiece and the first slotted part and the second slotted part.

[0039] like Figure 4 and Figure 6As shown, the unloading mechanism includes a cylinder 29 and a hook. The cylinder 29 is fixedly connected in the frame 1. The piston end of the cylinder 29 is fixedly connected with a connecting plate 30. The connecting plate 30 abuts against the bottom of the receiving block 21. A connecting rod 31 is fixedly connected to the side of the frame 1 close to the cylinder 29. The bottom of the hook is connected to the connecting rod 31. The hook includes a fixed end 32 and a movable end 33. The fixed end 32 is fixedly connected to the connecting rod 31. The movable end 33 is rotatably connected to the end of the fixed end 32 away from the connecting rod 31. A torsion spring 34 is provided at the connection between the movable end 33 and the fixed end 32. Pushing the movable end 33 can make the movable end 33 rotate toward the side of the fixed end 32. After loosening the movable end 33, the torsion spring 34 can drive the movable end 33 to return to its original state. A plurality of fixed blocks 35 and a plurality of fixed blocks 36 are slidably connected to the frame 1, and the fixed block 35 is arranged above the fixed block 36. An opening 37 is provided on the connecting rod 31 for the fixed block 35 and the fixed block 36 to be inserted, and a magnetic block 39 is fixedly connected in the opening 37. The fixed block 35 and the fixed block 36 are detachably connected to the magnetic block 39. A collection frame 38 is provided on the frame 1 below the connecting rod 31.

[0040] After the workpiece is processed, the workpiece is driven to the cylinder 29 by the loading tray 18, and then the cylinder 29 is started, so that the cylinder 29 pushes the workpiece upward until the workpiece can push the movable end 33 to rotate the movable end 33, and then the workpiece is pushed upward until it exceeds the movable end 33. At this time, the movable end 33 is restored to its original state under the action of the torsion spring 34, and then the piston of the cylinder 29 is retracted to make the workpiece descend until the workpiece is hung on the movable end 33. At this time, the pneumatic clamping block 22 is released, and the workpiece can fall along the fixed end 32 and the connecting rod 31, thereby realizing the automatic removal of the workpiece. In the process of collecting the workpiece, the fixed block 1 35 can be removed, and the fixed block 2 36 can fix the connecting rod 31 alone. After a certain number of workpieces are collected, the fixed block 1 35 is connected to the opening 37 at the top of the connecting rod 31, and then the fixed block 2 36 is removed, so that the workpiece enters the collection frame 38 along the connecting rod 31 for collection.

[0041] The processing process is as follows:

[0042] When the workpiece needs to be processed, the workpiece is manually mounted on the pneumatic clamping block 22, and then the drive motor 19 is started, so that the drive motor 19 drives the loading plate 18 to rotate, so that the workpiece rotates to the side close to the mounting frame 2. At this time, the staff can continue to clamp the workpiece on the next pneumatic clamping block 22. When the workpiece is processed, the finger milling cutter 1 12 and the finger milling cutter 2 14 can be driven by the motor 1 3 and the motor 2 7 to move to clamp the workpiece in the middle, and then the mounting frame 2 is moved so that the mounting frame 2 can push the finger milling cutter 1 12 and the finger milling cutter 2 14 close to the workpiece, and then the workpiece is processed. After processing the workpiece, the loading tray 18 drives the workpiece to rotate to the cylinder 29, and then the cylinder 29 is started, so that the cylinder 29 pushes the workpiece to move upward until the workpiece can push the movable end 33 to rotate the movable end 33, and then the workpiece is continued to be pushed upward until the workpiece exceeds the movable end 33. At this time, the movable end 33 returns to its original state under the action of the torsion spring 34, and then the piston of the cylinder 29 is retracted to lower the workpiece until the workpiece is hung on the movable end 33. At this time, the pneumatic clamping block 22 is released, and the workpiece can fall along the fixed end 32 and the connecting rod 31, so that the workpiece can be removed.

[0043] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
