Description

Technical Field

[0001] The invention belongs to the technical field of profile-matching combined processing, and in particular relates to profile-matching combined processing equipment for a gearbox output shaft. Background Art

[0002] There are multiple features on the gear shaft, which often need to be processed through combined processing. However, when clamped and fixed multiple times, errors are likely to accumulate, resulting in reduced accuracy. During traditional gear shaft feature processing, during the cutting process, the tool and the workpiece must not only rotate relative to each other, but also increase the distance between the two during the tool's ascent and retraction process to avoid scratches on the machining surface by the back of the tool. In this way, the tool and the workpiece must each have two-dimensional movements of rotation and lifting, and the center axes of the two must also move back and forth relative to each other to facilitate feeding and retraction.

[0003] However, this traditional superposition structure design is too complicated and cumbersome, and also requires very high absolute positioning accuracy of each axis.

[0004] The above-mentioned traditional processing method is still based on the coordinate position control of the tool and the workpiece to ensure the processing accuracy, while the present invention takes a different approach and proposes a trajectory tool control method based on profiling. Summary of the invention

[0005] In order to solve the problems of complex structure, difficult control and high precision requirements during multiple axial movements, the present invention, based on the principle of profiling, proposes a reference path for controlling the movement of the tool through a meshing component, and on the basis of the reference path, the movement control of the tool relative to the basic path is completed through angle and position control; this solution simplifies the original complex action path, splits it, and converts it into two relatively simple movements that can be controlled by mechanical linkage.

[0006] The present invention also creatively proposes a transverse sliding feed mechanism, which can make the basic position of the sliding gear cutter gradually approach the gear shaft body through the intermittently triggered feed and retract assembly during the revolution, thereby achieving the technical purpose of gradually increasing the cutting depth; the elastic pressure plate can automatically unlock and retract the sliding gear cutter when it descends, and after the tool is reset, the limit position of the tool can be locked again by the first stop block. Therefore, in the process of lifting and lowering cutting, the technical effect of reciprocating feed and retract and cutting reset can be automatically achieved without the help of a complex electronic control module, only through an ingenious mechanical structure.

[0010] The cantilever frame is fixed on the gear shaft body by means of a mounting chuck. At this time, since the mounting chuck is not located at the end of the gear shaft body but in the middle close to the gear processing portion, the coaxiality between the gear shaft body and the mounting chuck is relatively easier to ensure during the clamping and fixing process of the mounting chuck.

[0017] The connection and angle match between the secondary shaft body and the rotating main shaft can be maintained by the telescopic universal joint, so that during the rotation of the cantilever frame, the sliding gear shaping cutter can always be at a correct angle regardless of the lateral position.

[0027] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The gear shaft body can be clamped and fixed from the bottom through the bottom fixing chuck.

This process requirement can significantly reduce the debugging and inspection time and reduce the processing difficulty.

[0028] (2) The cantilever frame is fixed on the gear shaft body by means of a mounting chuck. At this time, since the mounting chuck is not located at the end of the gear shaft body but in the middle close to the gear processing part, the coaxiality between the gear shaft body and the mounting chuck is relatively easier to ensure during the clamping and fixing process of the mounting chuck.

[0029] (3) When the gear shaft body and the mounting chuck are fixed, the cantilever frame is driven by an external device to rotate on the mounting chuck.

[0042] The gear shaft body 7 can be clamped and fixed from the bottom through the bottom fixed chuck 6. Since the tool and frame for gear shaping are based on the gear shaft body 7 itself, the coaxial accuracy requirement for clamping and fixing the bottom fixed chuck 6 and the gear shaft body 7 is not high. This process requirement can significantly shorten the debugging and detection time and reduce the processing difficulty.

[0043] The rotating frame 2 includes a mounting chuck 9, a cantilever frame 10 and an engagement assembly 11. The mounting chuck 9 is engaged with the gear shaft body 7. The cantilever frame 10 is rotatably mounted on the mounting chuck 9. The cantilever frame 10 can be installed and disassembled by the mounting chuck 9. The engagement assembly 11 is arranged on the cantilever frame 10.

[0044] The cantilever frame 10 is fixed on the gear shaft body 7 by means of the mounting chuck 9. At this time, since the mounting chuck 9 is not located at the end of the gear shaft body 7, but in the middle close to the gear processing portion 8, during the clamping and fixing process of the mounting chuck 9, the coaxiality between the gear shaft body 7 and the mounting chuck 9 is relatively easier to ensure.

[0045] The cantilever frame 10 is provided with a through slide groove portion 12 and a circular hole portion 13 .

[0046] The meshing assembly 11 includes a fixed gear 14, a rotating gear 15, a rotating spindle 16 and a lockable spindle seat 17. The fixed gear 14 is engaged with the gear shaft body 7, the lockable spindle seat 17 is disposed in the slide groove portion 12, the lockable spindle seat 17 is relatively fixed to the cantilever frame 10 through its own locking mechanism, the rotating spindle 16 is rotatably disposed in the lockable spindle seat 17, the rotating gear 15 is engaged with the rotating spindle 16, and the fixed gear 14 and the rotating gear 15 are meshed and connected.

[0047] When the gear shaft body 7 and the mounting chuck 9 are fixed, the cantilever frame 10 is driven by an external device to rotate on the mounting chuck 9. At this time, through the meshing of the fixed gear 14 and the rotating gear 15, the rotating main shaft 16 can rotate simultaneously while rotating around the gear shaft body 7, and the meshing of the fixed gear 14 and the rotating gear 15 is always maintained.

[0048] The number of teeth and the module of the fixed gear 14 and the gear processing part 8 are the same, and the number of teeth and the module of the rotating gear 15 and the sliding gear cutter 26 are the same. Therefore, through the connection between the rotating gear 15 and the sliding gear cutter 26, the angle of the sliding gear cutter 26 can always be kept matching the angle of the gear processing part 8 without angle feedback and control through electric control.

[0049] The top cooling mechanism 4 includes a vertical bracket 46 and a cooling assembly 47. The vertical bracket 46 is fixedly connected to the cantilever frame 10. A second slide groove portion 48 is provided on the vertical bracket 46. Another group of the secondary shaft slider 22 is slidably arranged in the second slide groove portion 48. Another group of return springs 24 is arranged between the bottom of the second slide groove portion 48 and the secondary shaft slider 22.

[0050] The cooling assembly 47 includes an oil pipe bracket 49 and a cooling nozzle 50 . The oil pipe bracket 49 is arranged on the vertical bracket 46 , and the cooling nozzle 50 is arranged in the oil pipe bracket 49 .

[0051] When the vertical support 46 rotates along with the cantilever frame 10 , the cooling nozzle 50 is always located above the cutting position, and the flowing liquid is used to dissipate heat for the cutting position.

[0052] The horizontal sliding feed mechanism 3 includes a secondary shaft assembly 18, a lifting blade inserting assembly 19, a blade advance and retract assembly 20 and a blade retract unlocking assembly 21. The secondary shaft assembly 18 is slidably arranged in the slide groove portion 12, the lifting blade inserting assembly 19 is slidably arranged on the secondary shaft assembly 18, the blade advance and retract assembly 20 is located in the cantilever frame 10, and the blade retract unlocking assembly 21 is arranged on the cantilever frame 10.

[0053] The secondary shaft assembly 18 includes a secondary shaft slider 22, a secondary shaft body 23, a return spring 24 and a telescopic universal joint 25, one group of which is slidably arranged in the slide groove portion 12, the secondary shaft body 23 is rotatably arranged in the secondary shaft slider 22, and a square shaft portion 35 is provided on the secondary shaft body 23. One group of the return springs 24 is arranged between the advance and retract tool assembly 20 and the secondary shaft slider 22, and both ends of the telescopic universal joint 25 are respectively fixedly connected to the rotating main shaft 16 and the secondary shaft body 23.

[0054] The connection and angle matching between the secondary shaft body 23 and the rotating main shaft 16 can be maintained by the telescopic universal joint 25, so that during the rotation of the cantilever frame 10, the sliding gear cutter 26 can always be at a correct angle regardless of the lateral position.

[0055] The lifting type slotting cutter assembly 19 includes a sliding slotting cutter 26, a hydraulic cavity 27 and a hydraulic telescopic rod 28. The sliding slotting cutter 26 is slidably mounted on the square shaft portion 35. The hydraulic cavity 27 is fixedly connected to the secondary shaft body 23. A joint portion 36 is provided on the hydraulic cavity 27. The hydraulic telescopic rod 28 is slidably mounted in the hydraulic cavity 27. The end of the hydraulic telescopic rod 28 is fixedly connected to the sliding slotting cutter 26.

[0056] The hydraulic cavity 27 can control the reciprocating lifting and sliding of the sliding gear cutter 26. When the sliding gear cutter 26 descends, the outer contour processing of the gear processing part 8 can be gradually completed by the sliding gear cutter 26 scraping the gear processing part 8.

[0057] The advance and retract tool assembly 20 includes a cutting depth adjustment block 29, an adjusting bolt 30, a lever bracket 31 and an elastic plate 32. The cutting depth adjustment block 29 is slidably arranged in the slide groove portion 12. One group of the return spring 24 is arranged between the cutting depth adjustment block 29 and the secondary shaft slider 22. The cutting depth adjustment block 29 is provided with an internal threaded sleeve portion 37. The adjusting bolt 30 is rotatably arranged in the circular hole portion 13. The adjusting bolt 30 and the internal threaded sleeve portion 37 are threadedly connected. The adjusting bolt 30 and the cantilever frame 10 cannot generate axial sliding. The end of the adjusting bolt 30 is annularly evenly provided with a rotating lever 38. The lever bracket 31 is arranged on the base 5. The top of the lever bracket 31 is provided with a fixed lever 39. The elastic plate 32 is fixedly connected to the cutting depth adjustment block 29. The elastic plate 32 is composed of a pressing block portion 40, a first stop block 41 and a second stop block 42. The elastic plate 32 is also provided with a through middle fork portion 43, and the telescopic universal joint 25 is located in the middle fork portion 43.

[0058] During the continuous and slow rotation of the cantilever frame 10, each time the fixed lever 39 is passed, the fixed lever 39 will move the rotating lever 38 to rotate the adjusting bolt 30 by a certain angle, so that during the rotation of the cantilever frame 10, the base position of the sliding gear cutter 26 will be continuously pushed toward the gear shaft body 7, thereby achieving the technical effect of cutting layer by layer from the outside to the inside.

[0059] The tool retraction unlocking assembly 21 includes a circular retaining ring 33 and an elastic pressure plate 34 . The circular retaining ring 33 is fixed to the bottom of the sliding gear cutter 26 . The elastic pressure plate 34 is fixed to the cantilever frame 10 . The elastic pressure plate 34 is composed of an elastic plate 32 portion 44 and a pressure plate portion 45 .

[0060] Through the cooperation of the circular retaining ring 33 and the elastic pressure plate 34, after the sliding gear cutter 26 completes a descending cutting, the secondary shaft slider 22 can be retracted with the secondary shaft body 23 by unlocking and lateral movement, thereby achieving the technical purpose of retracting and resetting the tool and avoiding the problem of the back of the tool scratching the cutting surface when resetting.

[0061] During specific use, the user first needs to complete the installation and fixation of the gear shaft body 7 through the bottom fixing chuck 6, and then complete the connection between the cantilever frame 10 and the gear shaft body 7 by installing the installation chuck 9 on the gear shaft body 7, and then drive the cantilever frame 10 to rotate slowly and continuously through an external drive device. Since the fixed gear 14 and the rotating gear 15 remain in meshing, and the number of teeth and module of the fixed gear 14 and the gear processing part 8 are the same, the number of teeth and module of the rotating gear 15 and the sliding gear cutter 26 are the same. Therefore, the process of the revolution and rotation of the sliding gear cutter 26 can be controlled by the process of the rotating gear 15 revolving around the gear shaft body 7. Before the connection of the telescopic universal joint 25, it can be ensured that the angle of the sliding gear cutter 26 can always be kept correct whether the sliding gear cutter 26 rises or falls, and whether it is feeding or retracting.

[0062] By means of liquid entering and discharging from the hydraulic cavity 27, the extension and retraction of the hydraulic telescopic rod 28 can be controlled, thereby controlling the reciprocating lifting and lowering of the sliding gear shaping cutter 26. When the sliding gear shaping cutter 26 is lowered, it has a small overlap with the unfinished gear processing part 8. The gear processing part 8 can be processed by the cutting of the sliding gear shaping cutter 26. During the cutting process, since the first stop block 41 has a blocking effect on the secondary shaft slider 22, when the sliding gear cutter 26 slides axially, the limit position of the lateral displacement is the position of the first stop block 41. When one cutting is completed, the circular retaining ring 33 will hit the elastic pressure plate 34 when the sliding gear cutter 26 continues to descend. At this time, the elastic plate 32 portion 44 is pressed down and the pressure block portion 40 is pressed through the pressure plate portion 45, so that the sliding gear cutter 26 is locked by the first stop block 41 through the downward pressure of the elastic plate 32. At the same time, the top end of the elastic plate 32 portion 44 will push the sliding gear cutter 26 to move horizontally during the descent of the sliding gear cutter 26, thereby completing the tool withdrawal. Then, in the process of the hydraulic telescopic rod 28 retracting and the sliding gear cutter 26 rising, the secondary shaft body 23, which has lost the push of the elastic plate 32 part 44, will slowly return to its original position under the elastic force of the return spring 24. Since the sliding of the secondary shaft slider 22 has a damping force, when the secondary shaft slider 22 forms a locking relationship with the first stop block 41 again, the sliding gear cutter 26 has been returned to the top. The sliding gear shaping cutter 26 also reciprocates and performs four steps of "cutting down", "retracting the cutter laterally", "resetting the cutter upward", and "feeding the cutter laterally" during the process of revolution and rotation around the gear processing portion 8; During the reciprocating cutting process, whenever the adjusting bolt 30 rotates and passes through the lever bracket 31, the rotating lever 38 will be rotated by the fixed lever 39 to a certain angle. When rotating, the adjusting bolt 30 will push the cutting depth adjustment block 29 toward the gear shaft body 7 to a certain distance through the threaded transmission between itself and the internal threaded sleeve part 37. At the same time, the elastic plate 32 will also approach the gear shaft body 7, thereby advancing the basic position of the secondary shaft body 23, thereby achieving the technical purpose of gradually increasing the cutting depth.

[0063] During the processing, liquid continuously flows out of the cooling nozzle 50 , and the cooling nozzle 50 is always located above the processing position.

[0064] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0065] The present invention and its embodiments are described above, and such description is not restrictive.

In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
