[0026] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the aluminum die casting locking auxiliary positioning tooling structure of the utility model in conjunction with the accompanying drawings.

[0027] like Figure 1-4As shown, the utility model is a locking auxiliary positioning tooling structure for aluminum die castings, including a fixed plate 1, a boss 2 is arranged in the middle part of the upper surface of the fixed plate 1, a groove 3 is arranged in the middle part of the upper surface of the boss 2, and a positioning pin 4 is arranged on the upper surface of the groove 3. The positioning pin 4 is arranged so that the user can set it on the positioning pin 4 through the hole sleeve on the aluminum die casting to achieve basic positioning of the aluminum die casting. The middle part of the upper surface of the left and right ends of the fixed plate 1 is provided with a movable seat 6 that can move along its length direction, and the middle part of the upper surface of the left and right ends of the fixed plate 1 is provided along its length direction. The bottom of the movable seat 6 is provided with a slide groove 19 that matches the guide rail 5, and the slide groove 19 is slidably connected to the guide rail 5. The setting of the guide rail 5 and the slide groove 19 at the bottom of the movable seat 6 plays a limiting role on the movable seat 6, making the movable seat 6 more stable and reliable when moving. The two movable seats 6 are provided with U-shaped openings 7 on opposite sides, and the upper surface of the fixed plate 1 is provided with L-shaped blocks 9 on both sides of the movable seat 6. The upper surface of the fixed plate 1 is provided with limit grooves 8 on both sides of the boss 2, which are parallel to the width of the fixed plate 1. The width of the limit groove 8 is consistent with the width of the L-shaped block 9, and the horizontal section of the L-shaped block 9 is fixedly connected to the limit groove 8 by screws. The setting of the limit groove 8 facilitates the rapid positioning and installation of the L-shaped block 9. The top of the vertical section of the L-shaped block 9 is rotatably connected to a pressure rod 10 through a rotating shaft 11, and a rubber pad 13 is provided at the bottom of the pressure rod 10 away from the rotating shaft 11. Through the setting of the rubber pad 13, when the aluminum die-casting is pressed and positioned, the rubber pad 13 will contact the aluminum die-casting to ensure that no indentation will appear on the product surface. A protrusion 20 is provided at the bottom of the pressure rod 10, and a connecting shaft 21 is provided on the side wall of the protrusion 20. An arc-shaped opening 22 is provided on the side wall of the U-shaped opening 7. The connecting shaft 21 passes through the arc-shaped opening 22 and is slidably connected thereto. The width of the connecting shaft 21 matches the width of the arc-shaped opening 22, and a stopper is provided at the end of the connecting shaft 21. When the movable seat 6 moves, the connecting shaft 21 slides in the arc-shaped opening 22 under the cooperation between the arc-shaped opening 22 and the connecting shaft 21, so that the connecting shaft 21 drives the pressure rod 10 to rotate with the axis of the rotating shaft 11 as the center of the circle, thereby realizing the clamping, fixing and loosening of the aluminum die-casting, and the clamping and positioning effect is good.

[0028] A first L-shaped rod 16 is arranged at the back of the movable seat 6, and a second L-shaped rod 17 is arranged at the bottom of the vertical section of the first L-shaped rod 16. The horizontal sections of the first L-shaped rod 16 and the second L-shaped rod 17 are parallel to the upper side of the fixed plate 1. A driving box 12 is arranged at the middle part of the bottom of the fixed plate 1 along its length direction. A driving mechanism for driving the two second L-shaped rods 17 to move in opposite directions at the same time is arranged in the driving box 12. The driving mechanism includes a double-axis motor 14 installed at the middle part of the bottom of the fixed plate 1. Both shafts of the double-axis motor 14 are connected to a screw rod 15. The screw rod 15 is rotatably connected to the driving box 12 through a bearing. The vertical section of the second L-shaped rod 17 is provided with a threaded hole threadedly connected to the screw rod 15. Both ends of the drive box 12 are provided with movable openings 18 for the horizontal movement of the second L-shaped rod 17. By driving the dual-axis motor 14, the two screw rods 15 are rotated at the same time, so that the two second L-shaped rods 17 can move along the length direction of the screw rods 15, so that the second L-shaped rod 17 drives the first L-shaped rod 16 to follow its movement, so that the first L-shaped rod 16 drives the movable seat 6 to move along the length direction of the fixed plate 1, thereby realizing the clamping and opening action of the control pressure rod 10. The entire device realizes the simultaneous action of four pressure rods 10 through one motor, which not only saves costs, but also makes the control simple and easy to operate, which can greatly reduce labor intensity and improve loading and unloading efficiency.

[0029] The working principle of the aluminum die-casting locking auxiliary positioning tooling structure is as follows: when in use, the four pressure rods 10 are in an open state, the aluminum die-casting is first placed in the groove 3, so that the hole on the aluminum die-casting is sleeved on the positioning pin 4, and then the dual-axis motor 14 is started to rotate the screw rod 15, so that under the action of the second L-shaped rod 17 and the first L-shaped rod 16, the two movable seats 6 move closer to each other, so that the four pressure rods 10 rotate at the same time with the axis of the rotating shaft 11 as the center of the circle, so that the rubber pads 13 at the ends of the four pressure rods 10 are in close contact with the upper surface of the aluminum die-casting, and the pressing and positioning of the aluminum die-casting can be completed.

[0030] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
