Description

Technical Field

[0001] The utility model belongs to the technical field of truck wheel lower arm processing, and more specifically relates to a truck wheel lower arm tooling fixture. Background Art

[0002] The lower arm is a mechanical tool that, through different link configurations, allows the suspension to automatically adjust camber and toe angles, as well as a specific steering angle for the rear wheels, when retracted. The principle is to design the constraint angles at the joints, allowing the suspension to actively adjust wheel alignment during compression. This design flexibility allows for precise matching and adjustment to the vehicle model. Therefore, multi-link suspension maximizes tire grip and improves the vehicle's handling limits, resulting in the best performance of all suspension designs.

[0003] Based on the above, the inventors found that the following problems exist: when the lower arm is processed, polished or welded, it needs to be fixed. The general fixing device is to install several fixing parts on a base, place the lower arm on the inside of the fixing parts, and restrict and fix the lower arm through the fixing parts on the side of the lower arm. This type of fixing part cannot be adjusted, which is inconvenient when fixing lower arms of different models, and will result in poor stability during fixation.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a truck wheel lower arm tooling fixture is provided in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a truck wheel lower arm tooling fixture to solve the current problem of inconvenience in fixing lower arms of different models.

[0006] The purpose and effect of the truck wheel lower arm fixture of the utility model are achieved by the following specific technical means:

[0007] A truck wheel lower arm tooling fixture comprises a base, a slide rail is installed on the base, a movable platform is movably provided on the slide rail, a movable platform is provided with a movable groove, two movable parts are movably installed inside the movable groove, a nut is installed at one end of the movable part, the movable part is threadedly connected to a fixed stud through the nut, a pressure block is installed at the lower part of the fixed stud, a connecting part is installed at the lower part of the movable platform, a mounting block is installed on the base, a rotating rod is rotatably installed on the mounting block, a group of bidirectional threads are provided on the rotating rod, and the rotating rod is threadedly connected to the connecting parts at the lower parts of the two movable platforms through the bidirectional threads.

[0008] Furthermore, two sliders are installed at the lower part of the movable platform, and the movable platform is slidably connected to the slide rail via the two sliders.

[0009] Furthermore, one end of the rotating rod is connected to a driving motor, an output end of the driving motor is transmission-connected to the rotating rod, and the driving motor is connected to the base.

[0010] Furthermore, an adjustment box is installed on the base, a screw is rotatably installed inside the adjustment box, and a movable protrusion is threadedly connected to the screw.

[0011] Furthermore, the size of the lower portion of the movable protrusion is adapted to the inner width of the adjustment box, a rotating member is rotatably mounted on the upper portion of the movable protrusion, a lifting stud is threadedly connected to the inner side of the rotating member, and a top plate is mounted on the upper end of the lifting stud.

[0012] Furthermore, one end of the screw is connected to a servo motor, the output end of the servo motor is transmission-connected to the screw, and the servo motor is connected to one end of the adjustment box.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The cam is pressed against the bottom surface of the lower arm and the cam is pressed against the top surface of the lower arm, thereby ensuring that the cam is in a state of equilibrium with the load-bearing structure.

[0015] In the utility model, a servo motor is used to drive the screw to rotate. When the screw rotates, it can drive the moving protrusion to move inside the adjusting box, thereby driving the lifting stud and the top plate to move to the lower part of the lower arm. Then, the rotating part is rotated to drive the lifting stud to rise. At this time, the top plate will push the lower arm to move upward, so that the side surface of the lower arm is separated from the base, which makes it convenient to process the lower part of the lower arm.

[0027] The utility model provides a truck wheel lower arm fixture, comprising a base 1, a slide rail 2 is mounted on the base 1, a movable platform 3 is movably arranged on the slide rail 2, a movable groove 5 is opened on the movable platform 3, two movable parts 6 are movably mounted inside the movable groove 5, a nut 7 is mounted on one end of the movable part 6, the movable part 6 is threadedly connected to a fixed stud 8 through the nut 7, a pressure block 9 is mounted on the lower part of the fixed stud 8, a connecting piece 10 is mounted on the lower part of the movable platform 3, a mounting block 11 is mounted on the base 1, and a rotating mounting block 11 is mounted on the mounting block 11. It is equipped with a rotating rod 12, which has a set of two-way threads 13 on it. The rotating rod 12 is threadedly connected to the connecting piece 10 at the bottom of the two movable platforms 3 through the two-way threads 13. The lower arm is lifted up by the lifting stud 19, and the upper surface of the lower arm is applied with force in conjunction with the fixing stud 8 and the pressure block 9 to fix the lower arm. The position of the lifting stud 19 and the top plate 20, as well as the position of the fixing stud 8 and the pressure block 9 can be adjusted to facilitate the fixation of lower arms of different models, thereby improving the overall practicality.

[0028] Among them, two sliders 4 are installed at the lower part of the moving platform 3. The moving platform 3 is slidably connected to the slide rail 2 through the two sliders 4. The cooperation between the two sliders 4 and the slide rail 2 can make the moving platform 3 more stable when moving.

[0029] Among them, one end of the rotating rod 12 is connected to a driving motor 14, the output end of the driving motor 14 is transmission-connected to the rotating rod 12, the driving motor 14 is connected to the base 1, and the rotating rod 12 is driven to rotate by the driving motor 14. When the rotating rod 12 rotates, a set of bidirectional threads 13 are used to drive the two moving platforms 3 to move inward synchronously.

[0030] Among them, an adjustment box 15 is installed on the base 1, and a screw 16 is rotatably installed inside the adjustment box 15. A moving protrusion 17 is threadedly connected to the screw 16. The lower size of the moving protrusion 17 is adapted to the inner width of the adjustment box 15. A rotating part 18 is rotatably installed on the upper part of the moving protrusion 17. The inner side of the rotating part 18 is threadedly connected to a lifting stud 19. The upper end of the lifting stud 19 is installed with a top plate 20.

[0032] In the present invention, first, the lower arm to be processed is placed on the base 1, and the lower surface of the lower arm is located on the top plate 20. When the position of the top plate 20 cannot completely correspond to the lower arm, the servo motor is started, and the screw 16 is driven by the servo motor to rotate. When the screw 16 rotates, it can drive the moving protrusion 17 to move inside the adjustment box 15, thereby driving the lifting stud 19 and the top plate 20 to move to the lower part of the lower arm, and then the rotating part 18 is rotated to drive the lifting stud 19 to rise. At this time, the top plate 20 will push the lower arm to move upward, so that the side of the lower arm and the base 1 are separated. The lower part of the lower arm can be easily processed by starting the driving motor 14, and the rotating rod 12 is driven to rotate by the driving motor 14. When the rotating rod 12 rotates, the two movable platforms 3 are driven to move synchronously inward through a set of bidirectional threads 13. When the two movable platforms 3 move to the upper side of the lower arm, the fixing stud 8 is rotated, so that the lower part of the fixing stud 8 can push the pressure block 9 to gradually fit into the upper surface of the lower arm. The lower arm is lifted up by the lifting stud 19, and the upper surface of the lower arm is applied with the fixing stud 8 and the pressure block 9 to fix the lower arm.
