Description

Technical Field

[0001] This utility model relates to the field of shift fork manufacturing technology, specifically a grooving device for shift fork manufacturing. Background Technology

[0002] The shift fork is an important component in a car transmission. Its design needs to take into account the connection with the shift lever, the shifting of the intermediate shift wheel, and the change of the input-output speed ratio.

[0003] Automotive shift forks require slotting during production, primarily for ease of installation and securing, while also ensuring stability and safety during operation. However, existing shift fork slotting devices require workers to remove the pre-machined shift fork, insert a new one, and then repeat the slotting process. This method is inefficient and inconvenient for users.

[0004] To address the aforementioned problems, an improved grooving device for producing shift forks is now designed. Utility Model Content

[0005] The purpose of this invention is to provide a grooving device for producing shift forks, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0010] As a further embodiment of this utility model: the rotating mechanism includes a stepper motor, which is mounted on the upper end of a fixed frame directly above the center of the mounting plate. The output end of the stepper motor passes through the fixed frame and is mounted on the upper center of the mounting plate.

Then, a manual clamp is used to fix the shift fork inside the limiting mold base, which can achieve stable fixation of the shift fork and prevent the shift fork from moving during slotting.

[0016] This invention uses a stepper motor to rotate the mounting plate and switch the limiting mold bases on the upper part of the two opposite end faces of the mounting plate, which can realize dual-station operation. While grooving the shift fork, the machined shift fork is removed and replaced with a new shift fork, which effectively improves the grooving efficiency of the shift fork.

[0026] The moving mechanism includes a second linear moving module 6, which is vertically mounted on the inner wall of the fixed frame 7 opposite to the limiting mold base 14. A first linear moving module 5 is horizontally mounted at the output end of the second linear moving module 6. A first electric telescopic rod 8 is horizontally mounted at the output end of the first linear moving module 5. The first electric telescopic rod 8 is perpendicular to the vertical plane where the second linear moving module 6 and the first linear moving module 5 are located. The output end of the first electric telescopic rod 8 is mounted at the end of the grooving motor 10 that is far away from the grooving cutter head 11.

[0027] Both ends of the first linear motion module 5 are vertically mounted with sliding sleeves 4. A limiting rod 3 is slidably connected to the inner wall of the sliding sleeve 4. The upper end of the limiting rod 3 is mounted on the top of the fixed frame 7, and the lower end of the limiting rod 3 is horizontally mounted with a first fixing plate 2. The first fixing plate 2 is horizontally mounted on the upper end of the inner wall of the collection box 1.

[0028] When the grooving motor 10 and the grooving cutter head 11 are moved, the second linear motion module 6 is activated. The output end of the second linear motion module 6 drives the first linear motion module 5, the first electric telescopic rod 8, the grooving motor 10, and the grooving cutter head 11 to move, thereby realizing the vertical movement of the grooving motor 10 and the grooving cutter head 11. The first linear motion module 5 is activated, and the output end of the first linear motion module 5 drives the first electric telescopic rod 8, the grooving motor 10, and the grooving cutter head 11 to move, thereby realizing the horizontal movement of the grooving motor 10 and the grooving cutter head 11. The first electric telescopic rod 8 is activated, and the output end of the first electric telescopic rod 8 drives the grooving motor 10 and the grooving cutter head 11 to move, thereby moving the grooving motor 10 and the grooving cutter head 11 away from or closer to the limiting mold base 14.

[0029] The rotating mechanism includes a stepper motor 13, which is mounted on the upper end of a fixed frame 7 directly above the center of the mounting plate 15. The output end of the stepper motor 13 passes through the fixed frame 7 and is mounted at the center of the upper end of the mounting plate 15. A second fixed plate 19 is rotatably connected to the center of the lower end of the mounting plate 15 via a rotating rod. The second fixed plate 19 is horizontally mounted on the upper end of the inner wall of the collection box 1. A locking component for locking the mounting plate 15 is provided on the output shaft of the stepper motor 13.

[0030] The locking assembly includes a rotating disk 21, which is horizontally mounted on the output shaft of the stepper motor 13. Two pin holes 22 are arranged in a circular array around the output shaft of the stepper motor 13 on the rotating disk 21. A second electric telescopic rod 12 is vertically mounted on the top of the fixing frame 7 directly above the pin hole 22 on the side near the slotted motor 10. The output end of the second electric telescopic rod 12 is equipped with a pin 24 that cooperates with the pin hole 22. When the pin 24 is inserted into the pin hole 22, the vertical plane of the mounting plate 15 and the limiting mold base 14 is perpendicular to the first electric telescopic rod 8.

[0031] When switching the limiting mold base 14, first start the second electric telescopic rod 12 to retract. The output end of the second electric telescopic rod 12 drives the pin 24 to move, thereby moving the pin 24 out of the pin hole 22. Then start the stepper motor 13 to rotate 180 degrees. The output end of the stepper motor 13 drives the rotating disk 21, the mounting plate 15, and the limiting mold base 14 to rotate, thereby rotating the slotted fork to the open end of the fixed frame 7 and rotating the unslotted fork to face the slotting motor 10 and the slotting cutter head 11. Then start the second electric telescopic rod 12 to extend and retract. The output end of the second electric telescopic rod 12 drives the pin 24 to move, inserting the pin 24 into the pin hole 22, thereby fixing the rotating disk 21, the output shaft of the stepper motor 13, the mounting plate 15, and the limiting mold base 14.

[0032] The manual clamp includes a fixing frame 16, which is installed on the side wall of the limiting mold base 14 and is offset from the slotted position of the shift fork to avoid the fixing frame 16 affecting the slotted position of the shift fork. An internal threaded cylinder 26 is installed on the fixing frame 16. A screw 25 is rotatably connected to the inner wall of the internal threaded cylinder 26 by a thread. A pressure block 27 for pressing and fixing the shift fork inside the limiting mold base 14 is installed at the end of the screw 25 near the limiting mold base 14. A rotating block 17 for the operator to rotate the screw 25 is installed at the end of the screw 25 away from the pressure block 27.

[0033] A limiting mold base 14 is manufactured according to the model and size of the shift fork, and a fixing frame 16 is installed on the limiting mold base 14, with the fixing frame 16 offset from the slotted position of the shift fork. In use, the shift fork is placed inside the limiting mold base 14, and then the rotating block 17 is rotated. The rotating block 17 drives the screw 25 to rotate. Under the action of the thread, the screw 25 moves along the inner wall of the internal threaded cylinder 26, and drives the pressure block 27 to press and fix the shift fork inside the limiting mold base 14.

[0034] Working principle of a slotting device for producing shift forks:

[0035] Before use, a limiting mold base 14 is made according to the model and size of the shift fork, and a fixing bracket 16 is installed on the limiting mold base 14, so that the fixing bracket 16 is offset from the slotted position of the shift fork. Then, the two limiting mold bases 14 are respectively set on the two opposite end faces of the mounting plate 15. Then, the connecting plate 23 is fixed on the mounting plate 15 by screws, thereby fixing the limiting mold base 14 on the mounting plate 15.

[0036] When in use, the shift fork is placed inside the limiting mold base 14, and then the rotating block 17 is rotated. The rotating block 17 drives the screw 25 to rotate. Under the action of the thread, the screw 25 moves along the inner wall of the internal thread cylinder 26 and drives the pressure block 27 to press and fix the shift fork inside the limiting mold base 14.

[0037] Then, the second electric telescopic rod 12 is activated to retract. The output end of the second electric telescopic rod 12 drives the pin 24 to move, thereby moving the pin 24 out of the pin hole 22. Then, the stepper motor 13 is activated to rotate 180 degrees. The output end of the stepper motor 13 drives the rotating disk 21, the mounting plate 15, and the limiting mold base 14 to rotate, thereby rotating the slotted fork to the open end of the fixed frame 7 and rotating the unslotted fork to face the slotting motor 10 and the slotting cutter head 11. Then, the second electric telescopic rod 12 is activated to extend and retract. The output end of the second electric telescopic rod 12 drives the pin 24 to move, inserting the pin 24 into the pin hole 22, thereby fixing the rotating disk 21, the output shaft of the stepper motor 13, the mounting plate 15, and the limiting mold base 14.

[0038] Then, the grooving motor 10 is started. The output end of the grooving motor 10 drives the grooving cutter head 11 to rotate. Then, the grooving motor 10 and the grooving cutter head 11 are moved so that the grooving cutter head 11 grooves the fork on the limiting mold base 14. Specifically: the second linear movement module 6 is started. The output end of the second linear movement module 6 drives the first linear movement module 5, the first electric telescopic rod 8, the grooving motor 10 and the grooving cutter head 11 to move, realizing the vertical movement of the grooving motor 10 and the grooving cutter head 11. The first linear movement module 5 is started. The output end of the first linear movement module 5 drives the first electric telescopic rod 8, the grooving motor 10 and the grooving cutter head 11 to move, realizing the horizontal movement of the grooving motor 10 and the grooving cutter head 11. The first electric telescopic rod 8 is started. The output end of the first electric telescopic rod 8 drives the grooving motor 10 and the grooving cutter head 11 to move, realizing the grooving motor 10 and the grooving cutter head 11 away from or closer to the limiting mold base 14.

[0039] After the shift fork is slotted, the second electric telescopic rod 12 is activated to retract. The output end of the second electric telescopic rod 12 drives the pin 24 to move, thereby moving the pin 24 out of the pin hole 22. Then, the stepper motor 13 is activated to rotate 180 degrees. The output end of the stepper motor 13 drives the rotating disk 21, the mounting plate 15, and the limiting mold base 14 to rotate, thereby rotating the slotted shift fork to the open end of the fixed frame 7 and rotating the unslotted shift fork to face the slotting motor 10 and the slotting cutter head 11. Then, the second electric telescopic rod 12 is activated to extend and retract. The output end of the second electric telescopic rod 12 drives the pin 24 to move, inserting the pin 24 into the pin hole 22, thereby fixing the rotating disk 21, the output shaft of the stepper motor 13, the mounting plate 15, and the limiting mold base 14.

[0040] The above method enables continuous slotting of shift forks in the same batch.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
