Description

Technical Field

[0001] This utility model relates to the field of vehicle parts processing technology, and more specifically, to a shaping device for a vehicle gear selector lever. Background Technology

[0002] As a key component of a vehicle's transmission system, the gear selector lever typically has an approximate Z-shape, featuring two end plates spaced at a certain height difference and a connecting arm linking the two end plates. The connecting arm usually has stiffeners to enhance structural strength, while the end plates have bosses with hinge holes for connecting related front and rear components. Because the gear selector lever needs to withstand frequent load changes during vehicle operation, the precision of its structural shape has a significant impact on assembly quality and performance.

[0003] Currently, vehicle gear selector levers are typically manufactured using processes such as forging, machining, and heat treatment. However, due to the complex structure of the workpiece and the high requirements for dimensional accuracy, deviations in shape are easily caused during processing due to factors such as stress release and heat treatment deformation. To ensure that the workpiece meets design requirements, existing technologies usually inspect the workpiece's shape after machining. If any defects are found, repeated reshaping is required through manual hammering and other methods until the workpiece's shape meets the standard. This manual reshaping method is not only inefficient and reliant on the operator's experience, making it difficult to guarantee consistent reshaping accuracy, but also involves high labor intensity and production costs.

[0004] In summary, existing vehicle gear selector levers suffer from technical problems such as excessive reliance on manual operation in the shaping process, resulting in low efficiency and difficulty in controlling precision. Utility Model Content

[0005] The technical problem this utility model aims to solve is that the existing vehicle gear selector lever has a shaping process that relies too much on manual operation, resulting in low efficiency and difficulty in controlling precision.

[0006] To address the aforementioned problems, this utility model provides a shaping device for a vehicle gear selector lever, comprising an upper pressing platform and a lower pressing platform that press against each other. The opposing surfaces of the upper and lower pressing platforms are provided with shaping bending surfaces in opposite bending directions. These bending surfaces mate with the bending shape of the workpiece body of the gear selector lever to be shaped. A positioning groove is provided on the lower pressing platform, the inner contour of which matches the outer contour of the gear selector lever to be shaped, for positioning the lever within the groove. One of the upper and lower pressing platforms is used for fixed placement, while the other is used to connect to a press. Pressure is provided by the press to press the upper and lower pressing platforms together, thereby shaping the gear selector lever placed in the positioning groove into a desired shape.

[0007] The gear selector lever shaping device provided by this utility model has a main structure consisting of an upper pressure table and a lower pressure table. These two tables, in conjunction with a press or other equipment, press against each other. The surfaces of the two tables that meet are shaping bending surfaces that match the external bending contour of the gear selector lever to be shaped. When shaping the gear selector lever, the workpiece is first placed in the positioning groove of the lower pressure table to position it. The press or other similar equipment provides opposing force to the upper and lower pressure tables. The two pressure tables press the gear selector lever workpiece in the middle through this opposing movement. Because the press can provide precise and sufficient pressure to meet the workpiece correction requirements, the approximate mold structure of the upper and lower pressure tables allows for one-time shaping and correction of the complete workpiece through compression. This workpiece shaping method is simple in structure and easy to implement, and avoids the repeated inspection process after manual hammering. It achieves rapid and accurate one-time forming of the workpiece, effectively solving the technical problems of existing vehicle gear selector lever shaping processes that rely too heavily on manual operation, resulting in low efficiency and difficulty in controlling precision.

[0008] As a preferred embodiment, the upper pressure table is provided with a stepped structure at the transition position between the upper boss of the gear selector lever to be shaped and the workpiece body. The edges of the stepped structure are rounded and chamfered. This design makes the device more adaptable to the external structure of the gear selector lever workpiece itself. The gear selector lever workpiece itself has a plate-shaped workpiece body with a curved arc. Bosses are provided at both ends of the workpiece body. The thickness of the bosses is greater than that of the workpiece body. To accommodate the shaping and bending surface of this structure, a stepped structure is provided at the corresponding transition position between the bosses and the workpiece body. To avoid damaging the integrity of the gear selector lever workpiece with the pressure action of the pressure table, the edges of the stepped structure are rounded and chamfered.

[0009] As a preferred embodiment, the bottom surface of the positioning groove is provided with an inner groove that mates with the shape of the stiffening plate and boss on the selector lever to be shaped, thereby fitting the contour of one side of the selector lever to be shaped into the shape of the positioning groove. This design optimizes the positioning groove structure common in the above-mentioned technical solutions by providing an inner groove on the bottom surface of the positioning groove. The shape of the inner groove corresponds to the stiffening plate and boss on the selector lever, allowing the workpiece to be completely submerged in the positioning groove. This design increases the contact area between the surface of the workpiece to be shaped and the inner wall of the positioning groove, disperses the pressure of the pressure table on the surface structure of the workpiece during shaping, and avoids damage to the surface structure of the workpiece due to the shaping action.

[0010] As a preferred embodiment, the upper and lower pressure tables are provided with assembly positioning platforms protruding from the sidewalls on the side opposite to their respective forming and bending surfaces. These assembly positioning platforms have assembly holes penetrating their thickness direction for mounting and fixing to an external press or processing table. This design optimizes the external structure of the upper and lower pressure tables, providing a preferred pressure table fixing design that ensures accurate positioning of the two pressure tables during workpiece forming. The assembly positioning platform structure secures the two pressure tables to the press providing pressure and the fixed processing table respectively, preventing positional misalignment of the pressure tables and thus avoiding damage to the workpiece shape.

[0011] As a preferred embodiment, each of the upper and lower pressure platforms is provided with guide holes. The guide holes of the upper and lower pressure platforms are positioned opposite each other and are used to guide and limit the relative movement of the upper and lower pressure platforms by inserting a positioning rod. This design further optimizes the assembly positioning platform structure based on the above-mentioned structure by providing oppositely positioned guide holes on the assembly positioning platforms of the upper and lower pressure platforms. The guide holes of the upper and lower pressure platforms are located on the same vertical line. The guide holes are used to insert guide rods, which are fixedly mounted on the processing table or press surface used to fix the pressure platforms. The guide rods pass through the guide holes to guide the relative movement of the upper and lower pressure platforms, ensuring accurate relative positioning during their relative movement and improving the accuracy of the shaping action.

[0012] As a preferred embodiment, the inner wall of the positioning groove has a preset angle, making the opening area of ​​the positioning groove larger than the bottom area. This design optimizes the surface opening structure of the positioning groove on the lower pressure table, and processes the inner wall of the positioning groove to have an angled structure, making the opening area of ​​the positioning groove larger than the bottom surface. This structure makes it easier to place the workpiece to be shaped into the positioning groove, further improving the efficiency of the shaping process.

[0013] As a preferred embodiment, a retrieval slot is provided on one side of the positioning trough. The retrieval slot is connected to the positioning trough via a side wall, facilitating the removal of the selection lever from the positioning trough after shaping. This design optimizes the removal of the workpiece from the positioning trough after shaping by providing a connected retrieval slot on one side of the positioning trough, leaving space between the positioning trough and the side of the selection lever workpiece, allowing operators to reach into the retrieval slot with their hands or auxiliary tools to assist in removing the workpiece.

[0018] refer to Figures 1-4 The following examples illustrate this. Figure 1 A schematic diagram of the overall structure of a vehicle gear selector lever shaping device provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the lower pressure platform of the shaping device for the gear selector lever in a vehicle and the structure on which the gear selector lever is placed; Figure 3A schematic diagram of the upper pressure platform of a vehicle gear selector lever shaping device provided by this utility model; Figure 4 A schematic diagram of the lower pressure platform of another vehicle gear selector lever shaping device provided by this utility model.

[0019] This utility model provides a shaping device for a vehicle gear selector lever, including an upper pressing platform 1 and a lower pressing platform 2 that press against each other. The opposing surfaces of the upper pressing platform 1 and the lower pressing platform 2 are provided with shaping bending surfaces 3 with opposite bending directions. The shaping bending surfaces 3 are matched with the bending shape of the workpiece body of the gear selector lever 9 to be shaped. The lower pressing platform 2 is provided with a positioning groove 4. The inner contour shape of the positioning groove 4 is consistent with the outer contour of the gear selector lever 9 to be shaped, and is used to place the gear selector lever 9 to be shaped into the positioning groove 4 for positioning. One of the upper pressing platform 1 and the lower pressing platform 2 is used for fixed placement, and the other is used to connect to a press. The press provides pressure to press the upper pressing platform 1 and the lower pressing platform 2 against each other, so as to shape the gear selector lever 9 placed in the positioning groove 4 into a shape that meets the requirements.

[0020] The gear selector lever shaping device provided by this utility model has a main structure consisting of an upper pressure table 1 and a lower pressure table 2. The two are pressed together with a press or other equipment. The surfaces of the two are forming bending surfaces 3 that match the external bending contour of the gear selector lever to be shaped. When the gear selector lever 9 needs to be shaped, the gear selector lever 9 workpiece is first placed in the positioning groove 4 of the lower pressure table 2 to position the workpiece. The press or other similar equipment provides the upper pressure table 1 and the lower pressure table 2 with the power to move in opposite directions. The two pressure tables squeeze the gear selector lever 9 workpiece in the middle through the opposite movement. Since the press can provide a large pressure that is precise and can meet the workpiece correction requirements, the upper and lower pressure tables 2 have an approximate mold structure, which can shape and correct the workpiece in one go by squeezing. The workpiece shaping method has a simple structure and is easy to implement. It can avoid the repeated inspection process after manual hammering and shaping, and achieve the accurate shaping of the workpiece in one go. It effectively solves the technical problems of existing vehicle gear selector levers where the shaping process relies too much on manual operation, resulting in low efficiency and difficulty in controlling accuracy.

[0021] In the technical solution provided in this embodiment, the upper pressure table 1 is provided with a stepped structure 6 at the transition position between the upper boss of the gear selector lever to be shaped and the workpiece body. The edges of the stepped structure 6 are rounded and chamfered. This design makes the device more adaptable to the external structure of the gear selector lever workpiece itself. The gear selector lever workpiece itself has a plate-shaped workpiece body with a bending arc. Bosses are provided at both ends of the workpiece body. The thickness of the bosses is greater than that of the workpiece body. To adapt to this structure, the upper pressure table 1 is provided with a stepped structure 6 corresponding to the transition position between the bosses and the workpiece body on the bending surface 3. To avoid the pressure action of the pressure table from damaging the integrity of the gear selector lever workpiece, the edges of the stepped structure 6 are rounded and chamfered.

[0022] In the technical solution provided in this embodiment, the bottom surface of the positioning groove 4 is provided with an inner groove 5 that mates with the shape of the stiffener and boss on the selector lever to be shaped, so as to fit the contour of one side of the selector lever to be shaped with the shape of the positioning groove 4. This design optimizes the structure of the positioning groove 4 in the above technical solutions. The inner groove 5 is provided on the bottom surface of the positioning groove 4, and the shape of the inner groove 5 corresponds to the stiffener and boss on the selector lever, so that the workpiece is completely sunk into the positioning groove 4. This design can increase the contact area between the surface of the workpiece to be shaped and the inner wall of the positioning groove 4, disperse the pressure of the pressure table on the surface structure of the workpiece during shaping, and avoid damage to the surface structure of the workpiece due to the shaping action.

[0023] In the technical solution provided in this embodiment, the upper pressure table 1 and the lower pressure table 2 are provided with assembly positioning tables 7 protruding from the sidewall on the side opposite to their respective forming and bending surfaces 3. The assembly positioning tables 7 are provided with assembly holes 8 penetrating their thickness direction for installation and fixation with an external press or processing table via the assembly holes 8. This design optimizes the external structure of the upper pressure table 1 and the lower pressure table 2, providing a preferred pressure table fixing design that ensures the accurate positioning of the two pressure tables during workpiece forming. The structure of the assembly positioning tables 7 secures the two pressure tables to the press providing pressure and the fixed processing table respectively, preventing positional displacement of the pressure tables from damaging the workpiece shape.

[0024] In the technical solution provided in this embodiment, each of the upper pressure platform 1 and the lower pressure platform 2 has a guide hole on its respective assembly positioning table 7. The guide holes of the upper pressure platform 1 and the lower pressure platform 2 are positioned opposite each other and are used to guide and limit the relative movement of the upper pressure platform 1 and the lower pressure platform 2 by passing a positioning rod through them. This design further optimizes the structure of the assembly positioning table 7 based on the above-mentioned structure. Guide holes with opposite positions are provided on the assembly positioning tables 7 of the upper and lower pressure platforms 2. The guide holes of the upper and lower pressure platforms 2 are located on the same vertical line. The guide holes are used to pass through the guide rods, which are fixedly installed on the processing table or press surface used to fix the pressure platforms. The guide rods pass through the guide holes to guide the relative movement of the upper pressure platform 1 and the lower pressure platform 2, ensuring that their positions are accurately aligned during the relative movement and improving the accuracy of the shaping action. A preferred guide hole design is that one guide hole is provided near both ends on each side of the assembly positioning table 7 of the upper pressure platform 1 and the lower pressure platform 2.

[0025] In the technical solution provided in this embodiment, the inner wall of the positioning groove 4 has a preset inclination angle, making the opening area of ​​the positioning groove 4 larger than the bottom area of ​​the positioning groove 4. This design optimizes the surface opening structure of the positioning groove 4 on the lower pressure table 2, and processes the inner wall of the positioning groove 4 into an inclination angle structure, making the opening area of ​​the positioning groove 4 larger than the bottom surface of the positioning groove 4. This structure makes it easier to place the workpiece to be shaped into the positioning groove 4, further improving the efficiency of the shaping process.

[0026] In the technical solution provided in this embodiment, a part-removal groove 10 is provided on one side of the positioning groove 4. The part-removal groove 10 is connected to the positioning groove 4 through a side wall, which is used to facilitate the removal of the selection lever from the positioning groove 4 after shaping. Based on the above technical solution, this design optimizes the removal of the workpiece from the positioning groove 4 after shaping. By providing a connecting part-removal groove 10 on one side of the positioning groove 4, space is left between the positioning groove 4 and the side of the selection lever workpiece, so that the operator can reach into the part-removal groove 10 with their hand or auxiliary tools to assist in the removal of the workpiece.
