Description

Technical Field

[0001] This utility model relates to the field of shift fork processing technology, specifically a multi-station shift fork gripping surface processing equipment. Background Technology

[0002] A shift fork is a component on a car's gearbox, connected to the gearshift lever and located at the lower end of the lever. It moves the intermediate shift wheel, changing the input / output speed ratio. Shift forks are primarily used for clutch shifting. During the manufacturing process, the two gripping surfaces of the shift fork (i.e., the upper and lower end faces of the two end protrusions) need to be machined to ensure a flat gripping surface.

[0003] For machining the gripping surface of shift forks, the prior art CN218555586U proposes a machining device for the gripping surface of shift forks, including a lathe. The lathe includes a headstock and a tool post. A turntable for positioning multiple shift forks is provided on the front side of the headstock. The device achieves machining of the gripping surface of shift forks by loading shift forks on the turntable and then rotating the turntable in conjunction with the cutting tool.

[0004] While the aforementioned device can process the gripping surface, it fixes the shift fork using a combination of a pressure plate and hexagonal screws. This method requires repeated screw removal and installation, which is cumbersome. To address this issue, existing technology CN219901220U proposes a shift fork gripping surface processing device. This device utilizes a snap-fit ​​fixing mechanism to quickly fix and disassemble the shift fork, solving the problem of repeated screw installation and removal. However, this method still requires manual fixing and loosening of the shift fork, which remains inconvenient in application. Therefore, we provide a multi-station shift fork gripping surface processing equipment to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station shift fork gripping surface processing equipment to solve the problems mentioned in the background art.

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

[0007] A multi-station shift fork gripping surface processing equipment includes a bottom cabinet, a worktable fixedly connected to the upper end of the bottom cabinet, a protective housing fixedly connected to the upper surface of the worktable, an installation port on one side of the protective housing, a cam divider fixedly connected to the worktable inside the installation port, a turntable fixedly connected to the output end of the cam divider, a servo motor installed on the connection port of the cam divider, the output end of the servo motor fixedly connected to the input shaft of the cam divider, a plurality of contour slots for placing shift forks fixedly connected to the turntable, the plurality of contour slots being evenly distributed, a processing component for cutting the gripping surface of the shift fork on the worktable, and a fixing component for fixing the shift fork during processing on the protective housing.

[0008] As a further embodiment of this utility model: a limiting ring rail is fixedly connected to the lower end edge of the turntable, and a support slide is fixedly connected to the position of the worktable inside the protective housing, with the support slide being slidably connected to the limiting ring rail.

[0009] As a further embodiment of this utility model: the processing component includes a mounting frame, which is fixedly connected to the worktable near the turntable.

A drive motor is fixedly connected to the sliding plate. A first electric push rod is fixedly connected to one side of the upper end of the mounting frame. The output end of the first electric push rod is slidably connected to the sliding plate. A cutting element for cutting the gripping surface of the shift fork is installed at the output end of the drive motor.

[0010] As a further embodiment of this utility model: the cutting component includes two milling cutter discs, which are fixedly connected to the output end of the drive motor. The milling cutter discs are provided with a number of equally spaced tooth blocks, and each tooth block on the two milling cutter discs is provided with an alloy cutter head. The alloy cutter head is fixedly connected to the tooth block on the milling cutter disc by screws. The alloy cutter head on the two milling cutter discs is used to cut the upper and lower surfaces of the shift fork gripping surface respectively.

[0011] As a further embodiment of this utility model: the fixing component includes a mounting frame, which is fixedly connected to the frame at the upper end of the protective housing. A second electric cylinder is fixedly connected to the middle of the lower end of the mounting frame, and a contouring pressure block that matches the contouring slot seat is fixedly connected to the output end of the second electric cylinder.

[0012] As a further improvement of this utility model: both sides of the upper end face of the contouring block are fixedly connected with limiting slide rods, and the limiting slide rods are slidably connected to both sides of the lower end horizontal plate of the mounting frame.

[0014] As a further improvement of this utility model: the protective enclosure is rotatably connected to a back door on the side away from the installation port, and the back door is provided with a door lock buckle.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model can form multiple workstations through the set turntable and multiple contour slot seats. Then, the turntable is driven to rotate intermittently by the cam divider and servo motor, which feeds the shift forks on the contour slot seats into the protective housing one by one for gripping and cutting. At the same time as cutting, the fixing component can fix the shift forks, so that when processing the shift forks, the operator only needs to place the shift fork to be processed into the contour slot seat. After the gripping and cutting is completed, the operator can directly take the shift fork out of the contour slot seat without manually clamping or disassembling the shift fork, which greatly improves the convenience of processing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-8 In this embodiment of the present invention, a multi-station shift fork gripping surface processing equipment includes a bottom cabinet 1. A workbench 2 is fixedly connected to the upper end of the bottom cabinet 1. A protective housing 5 is fixedly connected to the upper surface of the workbench 2. An installation port 3 is provided on one side of the protective housing 5. A cam divider 7 is fixedly connected to the workbench 2 inside the installation port 3. A turntable 13 is fixedly connected to the output end of the cam divider 7. A servo motor 6 is installed on the connection port of the cam divider 7. The output end of the servo motor 6 is connected to the cam divider. The input shaft is fixedly connected, and several contour slot seats 15 for placing shift forks are fixedly connected on the turntable 13. The contour slot seats 15 are evenly distributed. During operation, the servo motor 6 drives the internal components of the cam divider 7 to operate, converting the continuous rotational motion into the intermittent indexing rotational motion of the turntable 13. Whenever the turntable 13 completes one indexing rotation, the contour slot seat 15 fixed on the turntable 13 generates one station switch, and then the shift forks on the contour slot seat 15 can be sent into the protective housing 5 one by one for cutting.

[0027] The worktable 2 is equipped with a machining assembly for cutting the gripper face of the shift fork. The machining assembly includes a mounting frame 9, which is fixedly connected to the worktable 2 near the turntable 13. Two T-shaped rails 20 are fixedly connected to the upper end of the mounting frame 9, and a sliding plate 21 is slidably connected between the two T-shaped rails 20. A drive motor 11 is fixedly connected to the sliding plate 21. A first electric push rod 10 is fixedly connected to one side of the upper end of the mounting frame 9. The output end of the first electric push rod 10 is slidably connected to the sliding plate 21. A cutting element for cutting the gripper face of the shift fork is installed at the output end of the drive motor 11. When cutting the gripper face of the shift fork, the drive motor 11 drives the cutting element to rotate. Then, the first electric push rod 10 pushes the sliding plate 21 to move the drive motor 11 along the T-shaped rails 20, so that the rotating cutting element moves to the gripper face position, thereby realizing the cutting machining of the gripper face of the shift fork.

[0028] The cutting component includes two milling cutter discs 22, which are fixedly connected to the output end of the drive motor 11. Each milling cutter disc 22 has several equally spaced tooth blocks, and each tooth block of the two milling cutter discs 22 is equipped with an alloy cutter head 23. The alloy cutter head 23 is fixedly connected to the tooth blocks on the milling cutter disc 22 with screws. The alloy cutter head 23 on the two milling cutter discs 22 is used to cut the upper and lower surfaces of the shift fork gripping surface, respectively. During cutting, the milling cutter discs 22 are driven by the drive motor 11 to rotate at high speed. The rotation of the milling cutter discs 22 drives the alloy cutter head 23 to move accordingly. Then, the alloy cutter head 23 on the two milling cutter discs 22 gradually contacts the shift fork gripping surface, cutting the upper and lower gripping surfaces of the shift fork flat. At the same time, the alloy cutter head 23 is fixed to the milling cutter disc 22 with screws, which can be easily removed and replaced after the alloy cutter head 23 is worn or damaged.

[0029] The protective housing 5 is also equipped with a fixing component for fixing the shift fork during shift fork processing; the fixing component includes a mounting frame 12, which is fixedly connected to the upper frame of the protective housing 5, and a second electric cylinder 17 is fixedly connected to the middle of the lower end of the mounting frame 12. The output end of the second electric cylinder 17 is fixedly connected to a contouring pressure block 19 that matches the contouring slot seat 15; a limiting ring rail 16 is fixedly connected to the lower edge of the turntable 13; and a support slide 14 is fixedly connected to the position of the worktable 2 inside the protective housing 5, with the support slide 14 slidably connected to the limiting ring rail 16; Both sides of the upper end face of the contouring block 19 are fixedly connected to limiting slide rods 18, which are slidably connected to the lower end horizontal plate of the mounting frame 12. When the shift fork is fixed, the output end of the second electric cylinder 17 drives the contouring block 19 to move downward. The contouring block 19 moves downward and presses on the contouring groove seat 15, thereby fixing the shift fork. The limiting slide rods 18 can ensure the stability of the contouring block 19 when it moves up and down and avoid deviation. At the same time, the setting of the support slide 14 can support the position of the turntable 13 on the processing side, so that the turntable 13 will not deform when the contouring block 19 is pressed down.

[0030] The protective housing 5 is provided with a protective glass 4 above the turntable 13; a back door 8 is rotatably connected to the side of the protective housing 5 away from the installation port 3, and the back door 8 is provided with a door lock; the interior of the protective housing 5 can be observed through the protective glass 4, and the back door 8 can be easily opened when needed to inspect the internal components of the protective housing 5 or clean up the debris generated by cutting.

[0031] The working principle of this utility model is as follows: During operation, the servo motor 6 starts, driving the transmission components inside the cam divider 7 to rotate. The transmission components inside the cam divider 7 then drive the turntable 13 to rotate intermittently. Each rotation of the turntable 13 moves the contour slot seat 15 once, thus feeding the shift forks on the contour slot seat 15 into the protective housing 5 one by one. When the contour slot seat 15 is inside the protective housing 5, the output end of the second electric cylinder 17 actuates, causing the contour pressing block 19 to move downwards. The contour pressing block 19 presses down on the contour slot seat 15, thereby fixing the shift forks. Then, the drive motor 11 drives the milling cutter disc 22 at high speed. The rotation is simultaneous with the first electric push rod 10 pushing the sliding plate 21 to move the drive motor 11 along the T-shaped rail 20, so that the alloy cutter heads 23 on the two milling cutter discs 22 gradually contact the gripping surfaces of the shift fork, cutting the upper and lower gripping surfaces of the shift fork flat. Then the first electric push rod 10 drives the drive motor 11 to reset, and the second electric cylinder 17 drives the contouring pressure block 19 to reset. The above cutting process is completed during the intermittent static period of the turntable 13. After the cutting is completed, the contouring slot seat 15 changes position again under the intermittent rotation of the turntable 13, so that during processing, the operator only needs to take out the processed shift fork at the station outside the protective housing 5 and then place the new shift fork.

[0032] The second electric cylinder 17, the first electric push rod 10, the drive motor 11, and the servo motor 6 in this application are all conventional devices in this technical field. Their working principles and control methods are well known to those skilled in the art. Each electrical component is controlled by a controller, which is a programmable controller. Those skilled in the art can easily implement the corresponding control program and control circuit design through conventional programming methods, so they will not be described in detail here.

[0033] 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. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
