Description

Technical Field

[0001] This utility model relates to a composite cutting and forming device for high-precision automotive control levers. Background Technology

[0002] To meet the operational stability and safety requirements of automotive control levers, their machining process must strictly ensure dimensional accuracy (such as lever diameter tolerance and step positioning error), shape accuracy (such as axis straightness and end face flatness), and surface quality (such as roughness Ra value) after cutting and forming. Furthermore, automotive control levers typically require multiple machining processes, including rough cutting, semi-finish cutting, and finish cutting, with different types of cutting tools (such as rough milling cutters, finish turning tools, and drilling tools) required for each process.

[0003] However, current composite cutting forming devices for automotive control levers have cumbersome tool replacement processes in practical applications. Traditional devices require first disassembling the tool to be replaced, cleaning the installation station, then installing the new tool and recalibrating (such as calibrating the coaxiality of the tool axis with the machine tool spindle and zeroing the cutting edge position). The entire process involves many steps and is time-consuming. Especially in multi-process continuous machining scenarios, frequent tool replacements will significantly increase auxiliary machining time, seriously restricting the mass production efficiency of automotive control levers. In view of this, this utility model proposes a high-precision composite cutting forming device for automotive control levers to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision composite cutting and forming device for automotive control levers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A composite cutting and forming device for high-precision automotive control levers includes a cutting machine tool, on which a support frame is provided; A rotating circular plate is rotatably mounted on the support frame, an adjusting support plate is mounted on the rotating circular plate, and multiple sets of cutting tools are mounted on the adjusting support plate. A positioning component is also mounted on the support frame, and the positioning component cooperates with the adjusting support plate to position the adjusting support plate on the support frame.

[0006] As an improvement to the above technical solution, the adjusting support plate includes an adjusting circular plate, which is coaxially arranged with a rotating circular plate and connected to the rotating circular plate. The adjusting circular plate is provided with multiple sets of mounting plates around its periphery. The multiple sets of mounting plates are arranged in a circular array around the axis of the adjusting circular plate. The multiple sets of cutting tools are respectively mounted on the multiple sets of rotating circular plates.

[0007] As an improvement to the above technical solution, a positioning groove is provided on the support frame; The positioning component includes a positioning C-shaped plate, on which a positioning protrusion is provided, which is adapted to the positioning groove.

[0008] As an improvement to the above technical solution, the positioning C-shaped plate is provided with a mounting groove, and the positioning protrusion is provided in the positioning groove, so that the mounting plate is placed in the mounting groove for the positioning process.

[0009] As an improvement to the above technical solution, an movable gap is provided between the mounting plate and the support frame, and two sets of movable fixing plates are symmetrically arranged on the inner walls of both sides of the positioning C-shaped plate. The positioning protrusion is set in the positioning groove, so that the two sets of movable fixing plates are placed in the movable gap.

[0010] As an improvement to the above technical solution, the support frame is provided with a support positioning hole, and the mounting plate is provided with a mounting positioning hole, the support positioning hole and the mounting positioning hole are matched in position.

[0011] As an improvement to the above technical solution, the positioning C-shaped plate is provided with positioning connection holes, and the positioning connection holes, support positioning holes, and mounting positioning holes are matched in position; A pin is provided between the positioning connection hole, the support positioning hole, and the mounting positioning hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When it is necessary to change the cutting tool to cut the car control lever, there is no need to disassemble and recalibrate the original tool. Simply release the restriction of the positioning component on the adjusting support plate, and rotate the adjusting support plate by rotating the circular plate and the support frame. This will accurately switch the target cutting tool to the cutting area of ​​the cutting machine tool. Then, the positioning component will reposition the adjusting support plate to continue processing. This process avoids the cumbersome operation of traditional tool changing, significantly shortens the tool changing auxiliary time, and effectively improves the continuous processing efficiency of the car control lever. It is especially suitable for multi-process cutting and forming scenarios. When the car control lever is cut by the machine tool, the positioning component and the adjusting support plate form a stable fit, which can reliably position and constrain the adjusting support plate. This design can effectively avoid the problem of the adjusting support plate shaking or shifting under the action of cutting force, and ensure that the cutting tool on the adjusting support plate always stays in the preset cutting position. This ensures the dimensional accuracy, shape accuracy and surface quality of the car control lever cutting surface, and fully meets the technical requirements of high-precision forming of the car control lever.

[0015] 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.

[0016] Example: like Figure 1-8 As shown, this embodiment proposes a composite cutting and forming device for high-precision automotive control levers, including a cutting machine tool 10, on which a support frame 20 is provided; A rotating circular plate 21 is rotatably mounted on the support frame 20. An adjusting support plate 50 is mounted on the rotating circular plate 21. Multiple sets of cutting tools 40 are mounted on the adjusting support plate 50. A positioning component 30 is also mounted on the support frame 20. The positioning component 30 cooperates with the adjusting support plate 50 to position the adjusting support plate 50 on the support frame 20.

[0017] In this embodiment, when the car control lever is cut, the car control lever is placed on the cutting machine tool 10. Then, through the cooperation between the rotating circular plate 21 and the support frame 20, the adjusting support plate 50 is rotated, thereby causing the cutting tool 40 to rotate to the cutting position of the cutting machine tool 10 to cut the car control lever. Of course, when the cutting tool 40 cuts the car control lever, the adjusting support plate 50 is positioned by the positioning component 30. When it is necessary to replace the cutting tool 40 to cut the car control lever, first release the restriction of the positioning component 30 on the adjusting support plate 50, then adjust the different cutting tools 40 to face the cutting area of ​​the cutting machine tool 10 by adjusting the rotation of the support plate 50, and then reposition the adjusting support plate 50 by the positioning component 30. When the cutting tool 40 needs to be replaced to cut the car control lever, there is no need to disassemble and recalibrate the original tool. It is only necessary to first release the restriction of the positioning component 30 on the adjusting support plate 50. By rotating the circular plate 21 and the support frame 20, the adjusting support plate 50 is rotated, which can accurately switch the target cutting tool 40 to the cutting area of ​​the cutting machine tool 10. Then, the positioning component 30 is used to reposition the adjusting support plate 50 to continue processing. This process avoids the cumbersome operation of traditional tool replacement, significantly shortens the tool switching auxiliary time, and effectively improves the continuous processing efficiency of the car control lever, especially suitable for multi-process cutting and forming scenarios. When the car control lever is cut by the cutting machine tool 10, the positioning component 30 and the adjusting support plate 50 form a stable fit, which can reliably position and constrain the adjusting support plate 50. This design can effectively avoid the problem of the adjusting support plate 50 shaking or shifting under the action of cutting force, and ensure that the cutting tool 40 on the adjusting support plate 50 always stays in the preset cutting position, thereby ensuring the dimensional accuracy, shape accuracy and surface quality of the cutting surface of the car control lever, and fully meeting the technical requirements of high-precision forming of the car control lever.

[0018] Specifically, the adjusting support plate 50 includes an adjusting circular plate 52, which is coaxially arranged with the rotating circular plate 21 and connected to the rotating circular plate 21. The adjusting circular plate 52 is surrounded by multiple sets of mounting plates 51, which are arranged in a circular array around the axis of the adjusting circular plate 52. The multiple sets of cutting tools 40 are respectively mounted on multiple sets of rotating circular plates 21.

[0019] In this embodiment, multiple sets of mounting plates 51 are arranged in a circular array around the axis of the adjusting circular plate 52, so that multiple sets of cutting tools 40 mounted on the mounting plates 51 form a circumferentially evenly distributed layout. When the adjusting support plate 50 is rotated by rotating the circular plate 21 to switch tools, the circular array structure can ensure that the rotation trajectory and switching angle of each set of cutting tools 40 around the rotation center have a unified reference, avoiding the alignment deviation between the tool and the cutting area of ​​the cutting machine tool 10 after switching due to the tool layout offset. At the same time, the circumferentially evenly distributed mounting plates 51 can further ensure the positioning accuracy after tool switching, and meet the dimensional consistency requirements of multi-process cutting of automotive control levers.

[0020] Specifically, the support frame 20 is provided with a positioning groove 23; The positioning component 30 includes a positioning C-shaped plate 35, on which a positioning protrusion 34 is provided, and the positioning protrusion 34 is adapted to the positioning groove 23.

[0021] In this embodiment, the positioning groove 23 on the support frame 20 and the positioning protrusion 34 on the positioning C-shaped plate 35 form a matching and fitting structure. This fitting structure can serve as a precise guide reference for the installation of the positioning C-shaped plate 35 relative to the support frame 20. It can guide the positioning C-shaped plate 35 to quickly and accurately dock to the preset installation position, effectively avoiding the problems of skewness and misalignment that occur during the assembly of the positioning C-shaped plate 35. It significantly improves the convenience and accuracy of the assembly process of the positioning component 30, reduces the technical difficulty of manual assembly operations and the risk of positioning failure caused by assembly deviation.

[0022] Specifically, the positioning C-shaped plate 35 is provided with a mounting groove 31, and the positioning protrusion 34 is provided in the positioning groove 23, so that the mounting plate 51 is placed in the mounting groove 31 for the positioning process.

[0023] In this embodiment, the mounting groove 31 provides a dedicated space for accommodating and positioning the mounting plate 51. The groove contour can be adapted to the shape of the mounting plate 51. Combined with the precise fitting reference of the positioning protrusion 34 and the positioning groove 23, the positioning reference of the mounting plate 51 can be unified to the preset coordinate system of the positioning C-shaped plate 35. This effectively avoids the positioning reference drift problem caused by the lack of dedicated positioning space for the mounting plate 51, significantly improves the positional accuracy and attitude accuracy of the mounting plate 51 relative to the positioning C-shaped plate 35, and ensures that the positioning error of the mounting plate 51 in the positioning process is controlled within the preset range.

[0024] Specifically, an movable gap 60 is provided between the mounting plate 51 and the support frame 20, and two sets of movable fixing plates 33 are symmetrically arranged on the inner walls of both sides of the positioning C-shaped plate 35; The positioning protrusion 34 is disposed in the positioning groove 23, so that the two sets of movable fixing plates 33 are placed in the movable gap 60.

[0025] In this embodiment, the movable gap 60 provides a preset relative movement space between the mounting plate 51 and the support frame 20. After the two sets of movable fixing plates 33 are embedded in the gap, they can form a guiding constraint on the relative movement of the mounting plate 51 and the support frame 20. This allows the two to make necessary relative displacements within a preset range, while limiting unintended deviations beyond the orientation through the matching and cooperation of the movable fixing plates 33 and the movable gap 60. This effectively avoids motion interference or stress concentration problems caused by rigid connections, and significantly improves the motion adaptability and reliability of the structure under dynamic working conditions.

[0026] Specifically, the support frame 20 is provided with a support positioning hole 22, and the mounting plate 51 is provided with a mounting positioning hole 53, and the support positioning hole 22 and the mounting positioning hole 53 are matched in position.

[0027] In this embodiment, after the support positioning hole 22 is aligned with the mounting positioning hole 53, it is convenient to position the C-shaped plate 35 between the support frame 20 and the mounting plate 51.

[0028] Specifically, the positioning C-shaped plate 35 is provided with a positioning connection hole 32, and the positioning connection hole 32, the support positioning hole 22, and the mounting positioning hole 53 are matched in position; A pin is provided between the positioning connection hole 32, the support positioning hole 22, and the mounting positioning hole 53.

[0029] In this embodiment, the position matching design of the support positioning hole 22, the mounting positioning hole 53 and the positioning connection hole 32 provides a unified spatial positioning reference for the support frame 20, the mounting plate 51 and the positioning C-shaped plate 35. When the pin passes through the three holes, the relative positions of the three can be forcibly constrained in the preset coordinate relationship through the precise cooperation between the holes and the pin. This effectively avoids the cumulative error caused by the independent positioning of each component, significantly improves the overall positioning accuracy of the multi-component assembly, and ensures that the positioning effect of the positioning C-shaped plate 35 on the mounting plate 51 and the supporting effect of the support frame 20 on the overall structure work together, providing a basic guarantee for the high-precision realization of the core functions of the device.
