Description

Technical Field

[0001] The utility model relates to the technical field of pedal group welding fixture devices, and particularly relates to a brake pedal group welding fixture. Background Technique

[0002] The automotive brake pedal is a pedal that restricts power. There is a small pedal on the brake that is connected to the brake lever. The automotive brake pedal is used to decelerate and stop the vehicle. It is one of the five major operating parts of an automobile and is used very frequently. There needs to be a welded connection between the automotive brake pedal arm and the brake pedal. When welding, there is no suitable fixture to restrict the position of the pedal arm, and it is easy for the pedal arm to be welded skewed when welding with the brake pedal. Group welding belongs to tack welding, where all parts are welded together. Full welding is to weld all the weld seams solid. Generally, when using thin materials, because thick materials are basically fully welded, there are not many requirements for full welding of thin materials. Intermittent welding is to weld every other section, and intermittent welding can occur for both thin and thick materials.

[0003] For example, an automatic positioning welding fixture for an automotive brake pedal arm with the publication number of CN219767200U includes a bottom plate. A reverse L-shaped fixing frame is fixedly installed at the upper end of the bottom plate. An electric hydraulic rod is fixedly installed at the top of the reverse L-shaped fixing frame. One end of the piston rod of the electric hydraulic rod penetrates through the reverse L-shaped fixing frame and is fixedly connected to a movable pressing plate. A supporting component is arranged below the bottom plate and above the movable pressing plate. The supporting component includes a concave-shaped fixing frame. A supporting plate is arranged at the upper end of the concave-shaped fixing frame. A rotating bearing is fixedly embedded in the center of the bottom of the supporting plate. A threaded rod is fixedly inserted into the inner ring of the rotating bearing, and one end of the threaded rod penetrates through the concave-shaped fixing frame and is connected to a knob. A pedal placement groove is opened at one end of the bottom plate away from the supporting component.

[0004] The above device drives the supporting plate to rise and fall through the threaded rod, and the rotating bearing and two groups of limiting rods cooperate to limit the supporting plate, facilitating the adjustment of the height of the supporting plate. The movable pressing plate and the supporting plate cooperate to clamp and fix the brake pedal arm. Two groups of limiting plates cooperate to guide and limit the unclamped end of the brake pedal arm, restricting the position of the pedal arm and increasing the stability of the brake pedal arm, avoiding the situation that the pedal arm is easily welded skewed when welding with the brake pedal. However, in the case of automotive pedals, the welding positions of most pedals are on the back side of the pedal, and the above pedal fixing fixture is not suitable for the pedal slots of different models and sometimes also blocks the welding position on the back side, causing inconvenience in welding.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:

[0022] Figure 1 This is the front overall view of the device. The main body is a hydraulic operation box 1. A flat operation board 2 is installed at the upper end of the hydraulic operation box 1. The flat operation board 2 is installed at the upper end of the hydraulic operation box 1 by welding. And contraction ends 3 are provided on both sides of the upper end of the flat operation board 2. At the same time, support columns are inserted in the center of the contraction ends 3. A hydraulic box is installed at the lower end of the contraction ends 3 to effectively control the support columns. The height of the support columns is effectively controlled by the operation buttons on the upper surface of the hydraulic operation end 6 provided on one side. A support board 5 is installed at the upper end of the support columns. And fixing ends are assembled on both sides of the support board 5. The fixing ends inlay the support board 5 at the top of the support columns to ensure that the heights of the two support columns at both ends are level. At the same time, a driving part 4 is installed in the middle of the support board 5. A support column 9 is assembled at the lower end of the driving part 4. And a rubber cushion block is connected to the lower end of the support column 9. A motor is provided inside the driving part 4. The support column 9 is pressed down by the output of the motor kinetic energy. At the same time, a brake pedal is provided below the rubber cushion block. The downward pressure of the support column 9 drives the rubber cushion block assembled at the bottom of the support column 9 to move, and presses down the brake pedal at the bottom;

[0023] Figure 2This is the overall side view of the device. The main body is a flat operation panel 2. A hydraulic end 7 is installed in the center of the flat operation panel 2, and a hydraulic column 8 is installed on the upper surface of the hydraulic end 7. At the same time, a top block 11 is assembled on the upper surface of the hydraulic column 8. The hydraulic system installed inside the hydraulic end 7 drives the lifting of the hydraulic column 8, which is controlled by the hydraulic operation end 6 arranged on the other side. It forms a fixture for the brake pedal in cooperation with the upper support column 9. And there is a moving frame on one side of the hydraulic end 7, which can adjust the position of the support column to avoid the situation that it cannot be stably clamped due to the small size of some pedal types;

[0024] Figure 3 This is the overall view of the lower fixture of the device. The main body is the top block 11. A rotating bottom end 14 is assembled in the middle of the top block 11, and a contact end face 12 is installed above the rotating bottom end 14. At the same time, a balance block 13 is inserted between the contact end face 12 and the rotating bottom end 14. The rotating bottom end 14 can adjust the rotation amplitude according to the direction of the force to reach the position suitable for the pedal angle. By setting the balance block 13, the device can return to its original position to prevent jamming when not in use. In addition, several meshing ports are provided on the contact end face 12, and most pedal surfaces are provided with raised blocks. By using the raised blocks on most pedal surfaces, the meshing ports can effectively mesh to ensure stability;

[0025] Figure 4 This is the partial view of the back fixed clamp of the device. The main body is the driving part 4. A derivative plate is installed on the back side of the driving part 4, and a concave end is provided on the surface of the derivative plate. At the same time, a universal joint 15 is assembled inside the concave end. A connecting block 17 is installed on the outside of the universal joint 15, and a rotating block is installed at the lower end of the connecting block 17. At the same time, a partition plate is assembled at the lower end of the rotating block 16. The lower end of the partition plate is connected to a telescopic arm, and an inert clamp 18 is installed at the lower end of the telescopic arm. A fixed clamp that can rotate freely is formed through each component to effectively fix the connecting rod. And most parts of this component are inert parts. Under normal circumstances, the weight of the connecting rod can be borne by the friction force carried by itself to ensure the stable effect.

[0026] During actual use, first retract the upper support column 9, place the brake pedal on the contact end face 12, use the design of the meshing ports to mesh the raised blocks on the pedal surface, and the position of the support column can be reasonably changed according to the size of the pedal. After the pedal is placed on the support column, start the upper driving part 4 to press down the support column 9. As the rubber cushion block is pressed down, the pedal is clamped. In addition, the fixed clamp arranged on the back side is used to fix the connecting rod to be welded, which is convenient for subsequent welding operations.

[0027] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
