Description

Technical Field

[0001] The present invention relates to the technical field of gear ring production, and in particular to a cutting device for producing high-performance planetary gears. Background Art

[0002] The planetary gear train is composed of a sun gear, planetary gears, an inner ring gear, and other auxiliary support and connection components. It is mainly used in transmissions in the industrial and automotive industries. Among them, the sun gear and planetary gears are both external tooth structures, while the inner ring gear is an internal tooth structure. Due to the particularity of the internal tooth structure, it cannot be processed using a commonly used gear hobbing machine, but requires a gear shaping machine for production.

[0003] Gear shaping is a method of machining a workpiece using the generating method. It involves driving a gear shaping cutter downward to cut the workpiece, thereby forming a gear. During machining, the gear shaping cutter and workpiece rotate according to specified parameters. After the gear shaping cutter moves downward to complete the downward cut, it must avoid contact between the workpiece and the chips during the return stroke, which could cause scratches on the machined surface. This requires a tool release during the return stroke, which involves driving the gear shaping cutter laterally away from the workpiece before moving it upward. Existing tool release systems typically use cam-lever, lead screw nut-multi-motor coordination, and gear-rack mechanisms to drive the gear shaping cutter for lateral movement. However, due to the rigid impact of the cam system at the reversal point and the clearance between the lead screw nut and gear-rack system, the gear shaping cutter will experience errors after movement. This can cause the position where the tool enters the workpiece to shift, resulting in an increase in the cumulative pitch error and making the internal gear ring fail to meet machining requirements. Furthermore, existing tool release systems require inspection and adjustment after repeated use, which undoubtedly increases machining time and affects the actual production process. Summary of the Invention

[0009] Preferably, the vertical slider is slidably connected to a side away from the first connecting rod with two blocking blocks arranged up and down. After the blocking block is pushed, its front end extends into the vertical slide groove and abuts against the sliding column in the horizontal frame.

[0010] Preferably, the guide column is fixedly connected to the inner side surface of the vertical slider with two guide bars, and the inner side surface is slidably connected to two horizontal push blocks, and two cylinders are fixedly connected inside the guide column, and the telescopic ends of the cylinders are fixed with oblique push blocks.

[0011] Preferably, when the telescopic end of the cylinder extends, the oblique push block pushes the horizontal push block to move toward the vertical sliding block and pushes the blocking block to extend into the vertical sliding groove.

[0012] Preferably, a separation groove is provided on one side of the vertical slider, the two guide bars are respectively located in different separation grooves, the heights of the two guide bars and the highest points of the horizontal push blocks are different, and the two horizontal push blocks are located in different separation grooves after being extended.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figures 1 to 10 An embodiment of the present invention provides a high-performance planetary gear production cutting device, comprising a frame 1, the frame 1 comprising a base 11 and a sliding frame 12 thereon, the base 11 being provided with a clamping portion 2, the clamping portion 2 being fixed with a workpiece 3, and further comprising:

[0031] The processing part 4 includes a driving device 41 fixed to one side of the sliding frame 12, the bottom surface of the driving device 41 is slidably connected to a sliding shell 42, the bottom end of the sliding shell 42 is hinged to a rotating shell 43, the bottom surface of the driving device 41 is fixedly connected to a guide column 44, the sliding shell 42 is fixedly sleeved with a horizontal frame 45, the horizontal frame 45 is slidably sleeved on the guide column 44, a vertical slider 46 is slidably connected inside the guide column 44, a first connecting rod 47 is hinged between the vertical slider 46 and the rotating shell 43, a vertical slide groove 461 is provided on the side of the vertical slider 46, a slide column inserted into the vertical slide groove 461 is fixed in the horizontal frame 45, and a gear cutter 413 driven to rotate by the driving device 41 is provided at the bottom of the rotating shell 43.

[0032] In this embodiment, the horizontal frame 45 is defined as the first position when it is at the highest point, the horizontal frame 45 drives the vertical slider 46 to move downward, and the bottom surface of the vertical slider 46 contacts the inner bottom surface of the guide column 44, which is defined as the second position, the horizontal frame 45 continues to move downward and moves from the top end to the bottom end of the vertical slide groove 461, which is defined as the third position, and the horizontal frame 45 is located at the bottom end of the vertical slide groove 461 and drives the vertical slider 46 to move upward, so that the top surface of the vertical slider 46 abuts the inner top surface of the guide column 44, which is defined as the fourth position.

[0033] In these four positions, when moving down from the first position to the second position, the gear shaping cutter 413 is in a vertical state; when moving down from the second position to the third position, the gear shaping cutter 413 rotates from the vertical state to the inclined state; when moving up from the third position to the fourth position, the gear shaping cutter 413 maintains the inclined state; when moving up from the fourth position to the first position, the gear shaping cutter 413 rotates to return to its original vertical state. By setting the above four positions, there is no need to perform a tool-releasing operation during the gear shaping process, thereby avoiding errors in the gear shaping cutter 413 after moving away from and approaching the workpiece 3.

[0034] When the horizontal frame 45 moves from the second position to the third position, the first connecting rod 47 rotates around one end hinged on the vertical slider 46, so that the gear cutter 413 moves away from the workpiece 3. When the horizontal frame 45 moves from the third position to the fourth position, since the sliding column of the horizontal frame 45 inserted into the vertical slide groove 461 is located at the bottom end of the vertical slide groove 461, the first connecting rod 47 still maintains an inclined state. When the horizontal frame 45 continues to move upward from the fourth position to the first position, the distance between the horizontal frame 45 and the first connecting rod 47 increases, causing the rotating shell 43 to rotate back to the vertical state, thereby resetting.

[0035] By using the existing drive device 41 to drive the gear shaping cutter 413 to move downward and rotate with the workpiece 3 according to specified parameters, the workpiece 3 is cut (the existing gear shaping machine already has a configuration for driving the gear shaping cutter 413 to move downward and rotating the gear shaping cutter 413 in conjunction with the workpiece 3). By cooperating with the provided guide column 44, vertical slider 46 and related structures, the horizontal frame 45 is able to move back and forth up and down. When cutting is completed, the gear shaping cutter 413 is rotated away from the workpiece, and is tilted for a period of time during the upward movement before returning to the center. Therefore, the gear shaping cutter 413 can be returned to its original position without the need for a cutter release operation, thereby avoiding the occurrence of processing errors caused by the cutter release.

[0036] In this embodiment, when the horizontal frame 45 is in the first position, the telescopic end of the upper cylinder 445 extends, so that the upper horizontal push block 442 pushes the front end of the upper blocking block 462 into the vertical slide groove 461;

[0037] When the horizontal frame 45 moves from the first position to the second position, the upper blocking block 462 is blocked by the corresponding guide bar 441, so the upper blocking block 462 is always in contact with the horizontal frame 45;

[0038] When the horizontal frame 45 reaches the second position, the upper blocking block 462 no longer contacts the corresponding guide bar 441, and thus no longer contacts the horizontal frame 45. At this time, the horizontal frame 45 can continue to move downward to the third position. At the same time, when the vertical slide 46 enters the second position, since the horizontal frame 45 has not yet contacted the air cavity 444 below, the lower cylinder 445 is not driven, so that the lower horizontal push block 442 is not pushed by the oblique push block 443, so that the lower horizontal push block 442 will not push the lower blocking block 462, so that the lower blocking block 462 can be retracted into the vertical slide 46 without extending into the vertical slide groove 461.

[0039] When the horizontal frame 45 moves to the third position, the cylinder 445 below is driven to cause the horizontal push block 442 below to push the blocking block 462 below, so that the blocking block 462 below contacts the horizontal frame 45 and fixes the horizontal frame 45 at the bottom end of the vertical slide groove 461;

[0040] When the horizontal frame 45 moves from the third position to the fourth position, the lower blocking block 462 no longer contacts the corresponding guide bar 441, thereby leaving the vertical slide 461. At this time, the horizontal frame 45 can continue to move up until it reaches the first position. At the same time, when the vertical slider 46 enters the fourth position, the upper blocking block 462 is not pushed by the corresponding horizontal push block 442, so that it retracts into the vertical slider 46, so that the horizontal frame 45 can move up from the fourth position to return to the initial first position.

[0041] In this embodiment, a drive shaft 411 is rotatably mounted in both the sliding housing 42 and the rotating housing 43. The two drive shafts 411 are connected by a universal joint 412. The gear shaping cutter 413 is fixedly sleeved on the bottom of the drive shaft 411 in the rotating housing 43. The upper drive shaft 411 is connected to the driving main shaft in the driving device 41, so that the drive shaft 411 is driven to move back and forth and rotate.

[0042] The universal joint 412 is of ball cage type, which is suitable for high-speed and high-precision transmission requirements, thereby ensuring that after the rotating housing 43 rotates, the gear shaping cutter 413 can still rotate synchronously with the main shaft of the driving device 41, avoiding the gear shaping cutter 413 being unable to align with the previously formed teeth after the rotating housing 43 is reset due to the different angular velocities of the two drive shafts 411.

[0043] In the existing gear shaping machine, when the gear shaping cutter 413 is driven to perform gear shaping, the main shaft of the gear shaping cutter 413 is driven to move downward. In this embodiment, by replacing the main shaft with two drive shafts 411, the gear shaping cutter 413 can be rotated toward the guide column 44 after the downward cutting is completed without the need for a tool release operation, thereby avoiding errors caused by tool release.

[0044] In this embodiment, the vertical slider 46 is slidably connected to the side away from the first connecting rod 47 and has two blocking blocks 462 arranged up and down. After the blocking block 462 is pushed, its front end extends into the vertical sliding groove 461 and abuts against the sliding column in the horizontal frame 45. By default, the blocking block 462 is driven by the spring on its side so that the front end is retracted into the vertical slider 46.

[0045] like Figures 4 to 9 As shown, after the blocking block 462 at the top is pushed by the adjacent horizontal push block 442, its front end extends into the vertical slide groove 461, and the blocking block 462 at the top abuts against the sliding column in the horizontal frame 45. In this way, after the horizontal frame 45 and the sliding shell 42 are driven downward by the driving device 41, the horizontal frame 45 will move to the second position. When the blocking block 462 is not pushed by the horizontal push block 442, the elastic force of the spring will drive the blocking block 462 to move away from the vertical slide groove 461, so that the horizontal frame 45 can move up and down relative to the vertical slider 46. Thus, after the horizontal frame 45 drives the vertical slider 46 to move downward through the upper blocking block 462 until the bottom surface of the vertical slider 46 abuts the inner bottom surface of the guide column 44, the horizontal frame 45 can continue to move downward. At this time, as the horizontal frame 45 continues to move downward, the sliding shell 42 and the rotating shell 43 move downward, thereby driving the rotating shell 43 to rotate toward the guide column 44 through the first connecting rod 47, so that the gear shaping cutter 413 no longer contacts the workpiece 3 during the upward return process, thereby preventing the gear shaping cutter 413 and the chips thereon from scratching the already formed teeth on the workpiece 3.

[0046] In this embodiment, two guide bars 441 are fixedly connected to the inner side surface of the guide column 44 facing the vertical slider 46, and two horizontal push blocks 442 are slidably connected to the inner side surface. Two cylinders 445 are fixedly connected inside the guide column 44, and an oblique push block 443 is fixed to the telescopic end of the cylinder 445. When the telescopic end of the cylinder 445 is extended, the oblique push block 443 pushes the horizontal push block 442 to move toward the vertical slider 46 and pushes the blocking block 462 to extend into the vertical slide groove 461.

[0047] In this embodiment, a separation groove 463 is opened on one side of the vertical slider 46, and the two guide bars 441 are respectively located in different separation grooves 463. The heights of the highest points of the two guide bars 441 and the horizontal push blocks 442 are different. After the two horizontal push blocks 442 are extended, they are located in different separation grooves 463.

[0048] In this embodiment, two air cavities 444 are fixedly connected to one side of the guide column 44, and the air cavity 444 is communicated with the cylinder 445 through a pipe. The two air cavities 444 are slidably connected to one side of the horizontal frame 45 with an extrusion rod. When the horizontal frame 45 is at the highest point and the lowest point of the moving path, the gas in the air cavity 444 is squeezed to drive the telescopic end of the cylinder 445 to extend.

[0049] When the blocking block 462 contacts the guide bar 441 and the horizontal push block 442 pushed out by the oblique push block 443 , the front end of the blocking block 462 extends into the vertical sliding groove 461 .

[0050] The gas in the air cavity 444 will be fully squeezed by the horizontal frame 45 to provide enough force to extend the telescopic end of the cylinder 445 and push the horizontal push block 442 only when the horizontal frame 45 is at the first position and the third position (i.e., the highest point and the lowest point).

[0051] When in the first position, the horizontal frame 45 contacts the extrusion rod of the air cavity 444 located above it, thereby compressing the air in the air cavity 444 and triggering the cylinder 445 located above. At this time, the oblique push block 443 located above will push the corresponding horizontal push block 442, so that the front end of the blocking block 462 extends into the vertical slide groove 461, so that the horizontal frame 45 can move with the vertical slider 46 after starting to move downward. At this time, since the blocking block 462 is pushed by the horizontal push block 442, it abuts against the guide bar 441 after moving downward, so that the extended blocking block 462 is always in an extended state.

[0052] As the horizontal frame 45 moves to the second position, due to the lack of obstruction by the guide bar 441, the extended upper blocking block 462 returns to the vertical slider 46 under the action of the spring, so that the horizontal frame 45 can move to the third position. At the same time, when in the second position, since the extrusion rod of the air cavity 444 below is not in contact with the horizontal frame 45, the lower cylinder 445 is not extended, so that the lower blocking block 462 is not pushed by the lower horizontal push block 442, and the horizontal frame 45 can move directly to the third position.

[0053] When the horizontal frame 45 moves to the third position, it contacts the extrusion rod of the lower air cavity 444, so that the telescopic end of the lower cylinder 445 extends, and then the lower horizontal push block 442 is pushed out by the corresponding oblique push block 443, so that the lower blocking block 462 is pushed by the horizontal push block 442. At this time, when the horizontal frame 45 moves to the fourth position, it will drive the vertical slider 46 to move upward together.

[0054] When the horizontal frame 45 moves from the third position to the fourth position, the blocking block 462 located below is no longer in contact with the corresponding guide bar 441, and is retracted into the vertical slider 46 under the restoring action of the spring, so that the horizontal frame 45 can continue to move upward to the first position. At the same time, in order to prevent the vertical slider 46 from sliding downward during the process of the horizontal frame 45 continuing to move upward, a magnet can be set on the top surface of the vertical slider 46 to offset its gravity, so that the vertical slider 46 is adsorbed in the guide column 44.

[0055] When the horizontal frame 45 moves from the second position to the third position, the distance between the horizontal frame 45 and the first connecting rod 47 is reduced, so that the first connecting rod 47 is hinged on one end of the vertical slider 46 and rotates, thereby causing the gear cutter 413 to rotate toward the guide column 44, so that when the horizontal frame 45 moves upward from the third position to the fourth position, the gear cutter 413 can always remain in an inclined state, avoiding the gear cutter 413 from contacting the workpiece 3 and damaging the workpiece 3. At the same time, since the driving device 41 only drives the gear cutter 413 to move up and down, the gear cutter 413 at this time can still maintain the previous rotation relationship with the workpiece 3 after returning to the vertical state, avoiding errors caused by the cutter letting go, which leads to misalignment of the teeth in subsequent processing.

[0056] In this embodiment, a first sliding groove 451 is provided on the bottom surface of the horizontal frame 45, and a horizontal slider 48 is slidably connected in the first sliding groove 451. A second connecting rod 49 is hinged on the side of the rotating shell 43, and the other end of the second connecting rod 49 is slidably connected in the horizontal slider 48. A downward push spring 491 is provided in the horizontal slider 48 to push the end of the second connecting rod 49 located in the horizontal slider 48 downward.

[0057] During the process of the horizontal frame 45 moving from the first position to the second position, when the gear shaping cutter 413 contacts the workpiece 3, since only the side of the gear shaping cutter 413 away from the guide column 44 contacts the workpiece 3, the gear shaping cutter 413 will be driven by the drive shaft 411 to have a tendency to rotate in the direction of the guide column 44. At this time, under the pressure of the second connecting rod 49, the rotating shell 43 cannot rotate in the direction of the guide column 44, so that the gear shaping cutter 413 remains in a horizontal state, avoiding the gear shaping cutter 413 from swinging when cutting the workpiece 3, resulting in errors in the cutting position.

[0058] When the horizontal frame 45 moves from the second position to the third position, the distance between the horizontal frame 45 and the first connecting rod 47 decreases, causing the second connecting rod 49 to move upward at one end in the horizontal slider 48, and at the same time drive the horizontal slider 48 to slide to the left side of the first sliding groove 451, so that the rotating shell 43 can swing. As the horizontal frame 45 moves upward, when it moves from the fourth position to the first position, the distance between the horizontal frame 45 and the first connecting rod 47 increases, causing the second connecting rod 49 to drive the horizontal slider 48 to slide to the right side of the first sliding groove 451, so that the second connecting rod 49 is reset. At the same time, a torsion spring can be provided at the hinge portion between the sliding shell 42 and the rotating shell 43 to assist the rotating shell 43 in rotating from the rotated state back to the vertical state.

[0059] In this embodiment, the clamping part 2 is composed of a clamp 21, a driving motor 22 and a lifter 23. The driving motor 22 is fixed at the top of the lifter 23 and drives the clamp 21 to rotate. After the lifter 23 works, the clamp 21 is driven to extend upward. The driving motor 22 and the lifter 23 are both located in the base 11.

[0060] By setting up a clamp 21 that can move up and down, before clamping the workpiece 3, the clamp 21 can be moved down so that the top surface of the clamp 21 is coplanar with the top surface of the base 11. In this way, the workpiece 3 can be directly provided to the clamping part 2 from the side of the base 11, making it convenient to load and unload the workpiece 3.

[0061] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
