[0014] The technical solution of this utility model will be further described in detail below with reference to specific embodiments: First Embodiment Please see Figure 1-5 A combination fixture for producing metal housings for car chargers includes a mounting bracket 1, an mounting hole 2 inside the mounting bracket 1, a centering clamping mechanism 3 at the bottom of the mounting bracket 1, an assembly frame 4 fixed at the bottom of the mounting bracket 1, and a rotating shaft 6 mounted at the bottom of the mounting bracket 1. The centering clamping mechanism 3 includes an electric push rod 31. One end of the output shaft of the electric push rod 31 is rotatably connected to a first movable plate 32 via a rotating shaft. The bottom of the first movable plate 32 is rotatably connected to a first transmission frame 33 via a rotating shaft. One end of the first transmission frame 33 is rotatably connected to a rotating frame 34 via a rotating shaft. One end of the rotating frame 34 is rotatably connected to a second transmission frame 35 via a rotating shaft. The end of the second transmission frame 35 away from the rotating frame 34 is rotatably connected to a second movable plate 36 via a rotating shaft. Adjustable clamping mechanisms 5 are installed on the top of both the first movable plate 32 and the second movable plate 36. Guide sleeves 37 are installed on the top of both the first movable plate 32 and the second movable plate 36. A guide rail 38 is fixed on the outside of the assembly frame 4. The electric push rod 31 and the mounting bracket 1 are fixedly connected. The rotating frame 34 and the rotating shaft 6 are connected by bearings. A guide groove is opened inside the guide sleeve 37. The guide sleeve 37 and the guide rail 38 are sliding fit components.
[0015] With the above settings, when clamping and positioning the automotive charger hardware housing workpiece, the corresponding automotive charger hardware housing workpiece is placed on the mounting bracket 1, specifically between the corresponding surfaces of the two adjustable clamping mechanisms 5. After starting the electric push rod 31, the output shaft of the electric push rod 31 drives the first movable plate 32 to move horizontally, causing the first movable plate 32 to drive one end of the first transmission frame 33 to rotate. The other end of the first transmission frame 33 drives one end of the rotating frame 34 to rotate, and the other end of the rotating frame 34 drives the second transmission frame 35 to rotate. The second movable plate 36 and the first movable plate 32 move synchronously in opposite directions. The guide sleeves 37 on the outer sides of the second movable plate 36 and the first movable plate 32 slide on the outer side of the guide rail 38, playing a guiding role. This allows the adjustable clamping mechanisms 5 to move synchronously and automatically center and align, thereby clamping and aligning the automotive charger hardware housing workpiece. This achieves rapid positioning and clamping, saving the time of aligning each workpiece individually, and automatically and accurately fixing irregularly shaped workpieces in the preset center position, which is beneficial to improving processing efficiency.
[0016] Second Embodiment Please see Figure 1-5 Based on the first embodiment, the adjustable clamping mechanism 5 includes a fixed plate 51, one end of which is connected to a support spring 52, and the other end of which is connected to a clamping connecting plate 53. Two adjustable threaded posts 54 are fixed on the outer side of the clamping connecting plate 53. A plastic handle 55 is fixed on one end of each adjustable threaded post 54. A first positioning nut 56 and a second positioning nut 57 are threadedly connected to the outer side of each adjustable threaded post 54. The tops of the first movable plate 32 and the second movable plate 36 are both fixed with fixed plates 51. The outer side of the plastic handle 55 is provided with anti-slip texture. A guide hole is opened inside the fixed plate 51, and the size of the guide hole is adapted to the size of the adjustable threaded post 54.
[0017] In summary, when clamping multi-sized automotive charger hardware housing workpieces, the position of the clamping connecting plate 53 needs to be adjusted to accommodate the clamping requirements of various sizes. During adjustment, first rotate the first positioning nut 56 and the second positioning nut 57 to move their corresponding surfaces away from the fixed plate 51. After releasing the limit on the adjustable threaded post 54, pull the plastic handle 55 horizontally. Adjust the position of the clamping connecting plate 53 using the adjustable threaded post 54. After the clamping connecting plate 53 moves to the appropriate position, rotate the first positioning nut 56 and the second positioning nut 57 again to make their corresponding surfaces fit against the fixed plate 51. This facilitates the adjustment and locking of the positions of the adjustable threaded post 54 and the clamping connecting plate 53, allowing the clamping connecting plate 53 to adapt to the clamping and positioning requirements of multi-sized automotive charger hardware housing workpieces.
[0018] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
