Description

Technical Field

[0001] This application relates to the field of automotive suspension machining, and in particular to fixtures for machining C-beams of automotive suspensions. Background Technology

[0002] The C-beam of an automotive suspension is a key structural component in an air suspension system. It primarily connects the vehicle frame to the air springs, providing support, cushioning, and guidance. C-beams are typically manufactured using hollow stamping and welding or one-piece molding processes, with a "C" or "U" shaped cross-section. They are lightweight and high-strength. Some designs enhance structural stability with diaphragms or side panels, and incorporate sleeves or locating pin holes to improve installation accuracy. During processing, automotive suspension C-beams are often secured using fixtures. These fixtures are specialized tools for fixing and testing automotive suspension C-beams, primarily used in the research, testing, and production of vehicle suspension systems. C-beam fixtures are a type of vehicle testing fixture specifically designed for suspension C-beams (a lightweight, high-strength support structure) to precisely fix them on test benches or production lines, ensuring their position and angle meet testing or assembly requirements.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional clamps are often used to fix C-beams of different sizes for automotive suspension. However, conventional clamps are mostly customized for C-beams of the same size, making it difficult to fix C-beams of different sizes for automotive suspension. This causes inconvenience in the environment of an auto repair shop where different C-beams of automotive suspension need to be processed.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem of fixtures being unable to secure automotive suspension C-beams of different sizes, this application provides a fixture for machining automotive suspension C-beams.

[0006] The technical solution for machining C-beams of automotive suspension provided in this application is as follows: A fixture for machining C-beams of automotive suspension includes a machining table and several adjusting rods. The machining table has a workpiece on its top. Two threaded grooves are formed on the surface of each adjusting rod, and connecting bases are threaded onto the surfaces of these grooves. A support frame is welded to the top of each connecting base, and a fixing clamp is rotatably connected to the top of the support frame. One end of both the fixing clamp and the support frame is movably mounted to the surface of the workpiece. The bottom end of each connecting base is slidably connected to the top of the machining table. The connecting bases are divided into two groups, symmetrically distributed about the machining table axis. The support frame has an "L"-shaped cross-section.

[0007] Preferably, an electric push rod is rotatably mounted on the bottom end of the fixing clamp, and the bottom end of the electric push rod is fixedly connected to the top of the connecting base.

[0008] Preferably, an auxiliary piece is fixedly installed on the top of the support frame, the top of the auxiliary piece is movably connected to the bottom of the processed material, and the auxiliary piece is a rubber sheet.

[0009] Preferably, the surface of the adjusting rod has two threaded grooves, which are symmetrically distributed about the adjusting rod axis, and a rotating handle is fixedly installed at one end of the adjusting rod.

[0010] Preferably, two sliding frames are rotatably mounted on the surface of the adjusting rod. The inner wall of the sliding frame is slidably connected to the surface of the processing table, and the cross-section of the sliding frame is U-shaped. The dimensions of the inner wall of the sliding frame are adapted to the dimensions of the surface of the processing table.

[0011] Preferably, the inner wall of the connecting base is rotatably connected to two pulleys, the bottom ends of the pulleys are slidably installed with the top of the processing table, and the two pulleys are symmetrically distributed about the processing table as an axis.

[0012] Preferably, a fixing block is fixedly connected to the surface of the connecting base, and a fixing bolt is threaded on the inner wall of the fixing block. The center of the fixing bolt is on the same straight line as the center of the fixing block, and the bottom end of the fixing bolt is movably connected to the top of the processing table.

[0013] In summary, this application includes the following beneficial technical effects: By installing the connecting base on the top of the processing table, the connecting base is threadedly connected to the threaded groove on the surface of the adjusting rod. A fixing clamp is connected to the top of the connecting base via a support frame, allowing the connecting base to slide on the adjusting rod and the processing table surface, thereby adjusting the overall position of the fixture. An electric push rod is rotatably connected to the bottom of the fixing clamp, and the bottom of the electric push rod is fixedly connected to the top of the connecting base, allowing the electric push rod to control the fixing clamp to secure the workpiece. A rubber auxiliary plate is installed on the top of the support frame to prevent friction between the workpiece and the support frame. Compared to existing technologies, this significantly improves the fixture's performance. Two sliding brackets can be installed on the surface of the adjusting rod to improve the stability of the connecting base after installation. Two threaded grooves are opened on the surface of the adjusting rod, and a rotating handle is installed at one end of the adjusting rod to control the two connecting bases synchronously, making it more convenient to adjust the clamp. Two pulleys are rotatably installed on the inner wall of the connecting base to facilitate the movement of the connecting base. A fixing block is installed on the surface of the connecting base, and a fixing bolt is threaded on the inner wall of the fixing block to connect with the surface of the processing table after the fixing bolt is rotated, thereby fixing the position of the connecting base; effectively improving the use effect of the device.

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0017] This application discloses a fixture for machining C-beams of automotive suspensions, as shown in the embodiments below. Figure 1 - Figure 2 The fixture includes a processing table 1. In use, after the processing table 1 is installed stably, the connecting base 3 is installed on the top of the processing table 1. The inside of the connecting base 3 is threadedly connected to the threaded groove 10 on the surface of the adjusting rod 4. A support frame 6 is welded to the top of the connecting base 3. A fixing clamp 7 is rotatably connected to the top of the support frame 6. The surface of the processing material 2 is fixed by means of the support frame 6 and the fixing clamp 7. The position of the fixture as a whole is adjusted by sliding the connecting base 3 on the surface of the adjusting rod 4 and the processing table 1. This makes it more convenient to fix processing materials 2 of different sizes.

[0018] Reference Figure 2An electric push rod 8 is rotatably connected to the bottom of the fixing clamp 7. The bottom of the electric push rod 8 is fixedly connected to the top of the connecting base 3. The fixing clamp 7 is rotated by adjusting its length with the help of the electric push rod 8, thereby controlling the fixing clamp 7 to fix the processing material 2, thereby improving the fixing effect of the processing material 2. A rubber auxiliary piece 9 is installed on the top of the support frame 6. The top of the auxiliary piece 9 is connected to the bottom of the processing material 2. The auxiliary piece 9 separates the support frame 6 from the processing material 2, thereby avoiding the situation where the processing material 2 and the support frame 6 rub against each other.

[0019] Reference Figure 3 - Figure 4 Two sliding frames 5 are installed on the surface of the adjusting rod 4. The inner wall of the sliding frame 5 is slidably connected to the surface of the processing table 1. The sliding frame 5 restricts the movement of the connecting base 3, thereby improving the stability of the connecting base 3 after installation. Two threaded grooves 10 are opened on the surface of the adjusting rod 4, and a rotating handle 11 is installed at one end of the adjusting rod 4. The rotating handle 11 controls the rotation of the adjusting rod 4 and controls the movement of the connecting base 3 on the surface of the threaded groove 10, thereby facilitating the synchronous control of the two connecting bases 3 and making it more convenient to adjust the fixture. Two pulleys 12 are rotatably installed on the inner wall of the connecting base 3. The bottom end of the pulley 12 is slidably connected to the top of the processing table 1. The pulleys 12 reduce the friction between the connecting base 3 and the processing table 1, making it more convenient to move the connecting base 3. A fixing block 13 is installed on the surface of the connecting base 3. A fixing bolt 14 is threadedly connected to the inner wall of the fixing block 13. The bottom end of the fixing bolt 14 is connected to the top of the processing table 1. After the fixing bolt 14 is rotated, it is connected to the surface of the processing table 1, thereby fixing the position of the connecting base 3 and effectively improving the overall stability of the fixture.

[0020] The implementation principle of the fixture for machining C-beams of automotive suspension in this embodiment is as follows: A connecting base 3 is installed on the top of the machining table 1. The interior of the connecting base 3 is threadedly connected to the threaded groove 10 on the surface of the adjusting rod 4. A support frame 6 is welded to the top of the connecting base 3, and a fixing clamp 7 is rotatably connected to the top of the support frame 6. This allows for the fixing of the surface of the workpiece 2 using the support frame 6 and the fixing clamp 7. Furthermore, the position of the fixture as a whole is adjusted by sliding the connecting base 3 on the surface of the adjusting rod 4 and the machining table 1. This makes it more convenient to fix workpieces 2 of different sizes. The bottom end of the fixing clamp 7 is rotatably connected to an electric push rod 8. The bottom end of the electric push rod 8 is fixedly connected to the top of the connecting base 3, so that the fixing clamp 7 can be rotated by adjusting its own length with the help of the electric push rod 8, thereby controlling the fixing clamp 7 to fix the processing material 2, thereby improving the fixing effect of the processing material 2. The top of the support frame 6 is equipped with a rubber auxiliary piece 9. The top of the auxiliary piece 9 is connected to the bottom end of the processing material 2, so that the support frame 6 and the processing material 2 can be separated by the auxiliary piece 9, thereby avoiding the friction between the processing material 2 and the support frame 6.

[0021] Two sliding brackets 5 can also be installed on the surface of the adjusting rod 4. The inner wall of the sliding bracket 5 is slidably connected to the surface of the processing table 1, so as to restrict the movement of the connecting base 3 by means of the sliding bracket 5, thereby improving the stability of the connecting base 3 after installation. Two threaded grooves 10 are opened on the surface of the adjusting rod 4, and a rotating handle 11 is installed at one end of the adjusting rod 4, so as to control the rotation of the adjusting rod 4 by means of the rotating handle 11, and control the movement of the connecting base 3 on the surface of the threaded groove 10, thereby facilitating the synchronous control of the two connecting bases 3, and making it more convenient when adjusting the fixture. Two pulleys 12 are rotatably mounted on the inner wall of the connecting base 3. The bottom end of the pulleys 12 is slidably connected to the top of the processing table 1, so as to reduce the friction between the connecting base 3 and the processing table 1 by means of the pulleys 12, making it more convenient to move the connecting base 3. A fixing block 13 is installed on the surface of the connecting base 3, and a fixing bolt 14 is threadedly connected to the inner wall of the fixing block 13. The bottom end of the fixing bolt 14 is connected to the top of the processing table 1, so that it can be connected to the surface of the processing table 1 after rotating by means of the fixing bolt 14, thereby fixing the position of the connecting base 3 and effectively improving the overall stability of the fixture.

[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
