Description

Technical Field

[0001] This utility model relates to the field of automotive parts calibration mold technology, specifically to a reverse gear shift fork calibration device. Background Technology

[0002] After being cast, reverse gear shift forks often experience problems such as deformation and cracking. Therefore, a calibration device is needed to calibrate the reverse gear shift fork before use. During calibration, the reverse gear shift fork is placed in the calibration groove, and then the top plate and the pressure plate are installed on the base plate. The electric telescopic rod is fixed on the mounting plate, and the top plate and the pressure plate are pushed by the electric telescopic rod, so that the pressure plate squeezes the reverse gear shift fork to achieve calibration.

[0003] A search revealed that publication number CN202320857621.6 discloses a shift fork correction mold, including a base plate connected to a correction mechanism. The base plate has a shift fork component inside it. The correction mechanism includes two slide grooves and a top plate. Slide strips are slidably connected inside the slide grooves. The bottom front and rear sides of the top plate are respectively fixedly connected to the top of the two slide strips. A pressure plate is fixedly connected to the bottom of the top plate. Two connecting rods are fixedly connected to the right side of the base plate. A mounting plate is fixedly connected between the two connecting rods. A fixing block is fixedly connected to the top of the mounting plate.

[0004] The aforementioned utility model achieves automatic calibration of the shift fork, thus eliminating the need for manual hammering and ensuring even force distribution. This avoids damage to the shift fork caused by hammering, extending its service life. Furthermore, the elimination of manual calibration saves time and effort, improving production efficiency. However, after calibration, the electric telescopic rod, top plate, and pressure plate must all be removed before the reverse shift fork can be taken off. Replacing the reverse shift fork takes considerable time, increasing the workload for workers and affecting the calibration efficiency.

[0005] Therefore, it is of great importance to design a reverse gear shift fork correction device to solve the above-mentioned defects. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model designs a reverse gear shift fork correction device. The device aims to solve the technical problem that after the lower gear shift fork is corrected, it takes a lot of time to replace the reverse gear shift fork, which not only leads to a high labor intensity for the workers, but also affects the correction efficiency of the reverse gear shift fork.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A reverse gear shift fork correction device includes a base, a positioning template placed at the rear end of the top of the base, a positioning groove formed inside the positioning template, a shift fork placed inside the positioning groove, a positioning plate hinged to the rear end of the top of the base above the shift fork, a locking plate hinged to the front end of the top of the base, a movable groove formed at the top of the base in front of the shift fork, and the bottom end of the locking plate engaging with the movable groove, a pressing plate slidably connected inside the locking plate, the left and right sides of the base being fixedly connected to the locking plate via locking mechanisms, and an electric push rod fixedly installed at the front end of the base, with the output end of the electric push rod abutting against the front end of the pressing plate.

[0009] As a preferred embodiment of this utility model, both ends of the positioning template are fixedly connected to pick-up and place plates, and pick-up and place slots are provided inside the base at positions corresponding to the pick-up and place plates.

[0010] As a preferred embodiment of this utility model, a positioning post is fixedly connected inside the positioning groove and inside the shift fork, and a top plate is slidably connected inside the front end of the positioning groove.

[0011] As a preferred embodiment of this utility model, a flip handle is fixedly installed on the top of the positioning plate, a mating edge is fixedly connected to the front end of the positioning plate, and a mating groove is provided at the rear end of the locking plate at a position corresponding to the mating edge.

[0012] As a preferred embodiment of this utility model, locking blocks are fixedly connected to the left and right ends of the locking plate at positions corresponding to the locking mechanism, and flip handles are fixedly connected to the opposite ends of the two sets of locking blocks.

[0013] As a preferred embodiment of this utility model, the locking mechanism includes connecting cylinders fixedly connected to the left and right sides of the base. Locking pins are slidably connected inside both sets of connecting cylinders, and the locking pins are inserted into the locking blocks. A return spring is sleeved on the outside of the locking pin and inside the connecting cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, through the coordinated design of the base, positioning template, positioning groove, positioning plate, locking plate, movable groove, pressing plate, and locking mechanism, when correcting the shift fork, it is placed inside the positioning groove, and the positioning pin penetrates into the rear end of the shift fork. Then, the positioning plate and locking plate are sequentially covered, and the locking mechanism is used to fix the locking plate, making the top plate flush with the inside of the positioning groove. The pressing plate is pushed by the electric push rod, and the pressing plate is used to press the shift fork for correction. During this process, the positioning pin is used to reinforce the interior of the rear end of the shift fork to prevent it from being affected during correction. When the shift fork is removed after correction, the locking mechanism is used to release the locking plate, control the electric push rod to retract, and then the locking plate and positioning plate are flipped open. Under the action of the top spring, the top plate is pushed up, which makes it easy to push the shift fork out from the inside of the positioning groove. Thus, the shift fork can be replaced without disassembling the parts, reducing the labor intensity of the workers and improving the correction efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0025] A reverse gear shift fork correction device includes a base 1, a positioning template 2 placed at the rear end of the top of the base 1, a positioning groove 3 inside the positioning template 2, a shift fork 4 placed inside the positioning groove 3, a positioning plate 5 hinged to the rear end of the top of the base 1 above the shift fork 4, a locking plate 6 hinged to the front end of the top of the base 1, a movable groove 7 opened at the top of the base 1 in front of the shift fork 4, and the bottom end of the locking plate 6 engaging with the movable groove 7, a pressing plate 8 slidably connected inside the locking plate 6, the left and right sides of the base 1 being fixedly connected to the locking plate 6 via locking mechanisms 9, and an electric push rod 10 fixedly installed at the front end of the base 1, with the output end of the electric push rod 10 abutting against the front end of the pressing plate 8.

[0026] Furthermore, both ends of the positioning template 2 are fixedly connected with pick-up and put-down plates 201, and pick-up and put-down slots 202 are opened in the base 1 at positions corresponding to the pick-up and put-down plates 201. The pick-up and put-down slots 202 facilitate the removal of the positioning template 2 from the base 1 using the pick-up and put-down plates 201, so that the positioning template 2 can be replaced separately after it is damaged, thereby reducing the cost of use.

[0027] Then, a positioning pin 301 is fixedly connected inside the positioning groove 3 and inside the shift fork 4. A top plate 302 is slidably connected inside the front end of the positioning groove 3. Both ends of the top plate 302 are fixedly connected to the inside of the positioning groove 3 through top springs 303. When aligning the shift fork 4, after it is placed inside the positioning groove 3, the positioning pin 301 penetrates into the rear end of the shift fork 4. Then, the positioning plate 5 and the locking plate 6 are sequentially covered, and the locking plate 6 is fixed by the locking mechanism 9, so that the top plate 302 and the positioning groove 3 are aligned. The interior is flush. The electric push rod 10 pushes the extrusion plate 8, and the extrusion plate 8 uses the extrusion plate 8 to press the shift fork 4 for correction. During this process, the positioning column 301 is used to reinforce the interior of the rear end of the shift fork 4 to avoid affecting the correction. After the correction is completed, when the shift fork 4 is removed, the locking mechanism 9 is used to release the locking plate 6. After the locking plate 6 and the positioning plate 5 are flipped open, the top plate 302 is pushed up under the action of the top spring 303, which makes it easier to push the shift fork 4 out of the inside of the positioning groove 3, thereby facilitating material removal and improving the correction efficiency.

[0028] Furthermore, a flip handle 501 is fixedly installed on the top of the positioning plate 5, and a mating edge 502 is fixedly connected to the front end of the positioning plate 5. A mating groove 503 is opened at the rear end of the locking plate 6 at the position corresponding to the mating edge 502. After the shift fork 4 is placed inside the positioning groove 3, the positioning plate 5 is covered by the flip handle 501 to limit the upper part of the shift fork 4. Then, the locking plate 6 is covered to make the mating groove 503 mate with the mating edge 502. After the locking plate 6 is fixed by the locking mechanism 9, the positioning plate 5 is fixed by the locking plate 6. Thus, when the shift fork 4 is corrected, the upper part is limited to ensure uniform force distribution.

[0029] Locking blocks 601 are fixedly connected to both ends of the locking plate 6 at positions corresponding to the locking mechanism 9. A flip handle 602 is fixedly connected to the opposite ends of the two sets of locking blocks 601. The locking plate 6 is rotated by the flip handle 602. After the locking plate 6 is closed, the locking blocks 601 are fixed by the locking mechanism 9, thereby fixing the locking plate 6 and the positioning plate 5. Then, the electric push rod 10 pushes the pressing plate 8, and the pressing plate 8 presses the shift fork 4 for correction. After the correction is completed, the locking mechanism 9 is operated to release the locking blocks 601. The locking plate 6 and the positioning plate 5 can be flipped open to remove the shift fork 4. Thus, the shift fork 4 can be replaced without disassembling the parts, which reduces the labor intensity of the workers and improves the correction efficiency.

[0030] Secondly, the locking mechanism 9 includes connecting cylinders 901 fixedly connected to the left and right sides of the base 1. Locking pins 902 are slidably connected inside both sets of connecting cylinders 901, and the locking pins 902 are inserted into the locking block 601. A return spring 903 is sleeved on the outside of the locking pin 902 and inside the connecting cylinder 901. A top ring 904 is fixedly connected on the outside of the locking pin 902 and at the rear end of the return spring 903. Under the action of the return spring 903, the top ring 904 is pressed against, so that the locking pin 902 is inserted into the interior of the locking block 601, thereby fixing the locking plate 6.

[0031] Finally, a locking pin 905 is fixedly connected to the outer side of the top ring 904. A slot 906 is provided on the outer side of the connecting cylinder 901 at the position corresponding to the locking pin 905. When taking out the shift fork 4, it is only necessary to pull the locking pin 902 and then rotate it to insert the locking pin 905 into the front end of the slot 906, thereby locking the locking pin 902 inside the connecting cylinder 901 and fixing it. Then the locking plate 6 and the positioning plate 5 can be opened to replace the shift fork 4.

[0032] In this embodiment, the specific implementation scenario is as follows: When calibrating the shift fork 4, after it is placed inside the positioning groove 3, the positioning pin 301 is inserted into the interior of the rear end of the shift fork 4. Then, the positioning plate 5 and the locking plate 6 are placed on top in sequence. The locking plate 6 is then fixed by the locking mechanism 9, so that the top plate 302 is flush with the interior of the positioning groove 3. The electric push rod 10 pushes the extrusion plate 8, and the extrusion plate 8 is used to extrude the shift fork 4 for calibration. During this process, the positioning pin 301 is used to reinforce the interior of the rear end of the shift fork 4 to prevent it from being affected during calibration. After calibration, when the shift fork 4 is removed, the locking mechanism 9 is used to release the fixing of the locking plate 6, and the electric push rod 10 is controlled to retract. Then, the locking plate 6 and the positioning plate 5 are flipped open, and the top plate 302 is pushed up by the top spring 303, so that the shift fork 4 can be easily pushed out of the interior of the positioning groove 3. The whole operation process is simple and convenient. This utility model can replace the shift fork 4 without disassembling the parts, which reduces the labor intensity of the workers and improves the calibration efficiency.
