[0020] refer to Figure 1 As shown, one embodiment of the utility model is:

[0021] The automobile parts positioning tool comprises a frame 1, on which a bearing platform 2 is rotatably mounted, U-shaped mounting arms 3 are arranged on both sides of the frame 1 and located on the bearing platform 2, the notches of the U-shaped mounting arms 3 are arranged opposite to each other, and a lead screw driving member is arranged between the two side plates of the U-shaped mounting arms 3, an extension plate 4 is arranged on the lead screw driving member, the extension plate 4 is located above the bearing platform 2, and a vacuum suction cup 5 is arranged on the extension plate 4.

[0022] Specifically, a servo motor 6 is disposed at the lower end of the frame 1 , and an output shaft of the servo motor 6 passes through the frame 1 and is provided with a mounting plate 7 , on which the supporting platform 2 is disposed.

[0023] Providing the mounting plate 7 to connect the support platform 2 is beneficial to increasing the contact area, improving stability, and facilitating installation and debugging.

[0024] The screw drive component includes a screw 8, which is rotatably installed between the two side plates. The side plates are provided with a screw motor 9 for driving the screw 8 to rotate. The screw 8 is provided with a screw nut 10. The extension plate 4 is fixedly connected to the screw nut 10. A guide rail 11 is provided on the bottom plate of the U-shaped mounting arm 3. A vertical plate 12 is provided at the end of the extension plate 4 facing away from the vacuum suction cup 5, and a slider 13 adapted to the guide rail 11 is provided on the vertical plate 12.

[0025] The vertical plate 12 and the vacuum suction cup 5 are arranged on both sides of the screw, which is conducive to balancing the force and improving the stability of the screw during operation. Further, a reinforcing brace 14 is arranged between the vertical plate 12 and the extension plate 4 to improve the connection strength between the vertical plate 12 and the extension plate 4.

[0026] The height of the extension plate 4 is adjusted by setting a lead screw drive, and the vacuum suction cup 5 adsorbs and fixes the workpiece. During the processing, the lead screw drive drives the vacuum suction cup 5 to move down and fix the workpiece. When adjusting the angle, the vacuum suction cup releases the workpiece and moves up under the action of the lead screw drive. Then the servo motor 6 drives the carrier to rotate to the adjusted position. If the position of the workpiece is normal, the vacuum suction cup 5 moves down to fix the workpiece; if the position of the workpiece is deviated, the vacuum suction cup 5 moves up to drive the workpiece to suspend in the air, and then the servo motor drives the carrier 2 to rotate in the opposite direction to the angle value to be adjusted according to the angle to be adjusted, and the vacuum suction cup 5 moves down to release the workpiece onto the carrier 2. Then the servo motor drives the carrier 2 to rotate forward to the angle value to be adjusted, and the vacuum suction cup 5 moves down to fix the workpiece. Through the multiple cooperation of the servo motor 6, the lead screw drive, and the vacuum suction cup 5, the position calibration of the workpiece on the carrier 2 can be achieved, ensuring the correct position of the workpiece on the carrier 2 and the processing accuracy of the workpiece.

[0027] In this embodiment, an anti-slip stopper 15 is provided on the upper portion of the lead screw 8 , and the anti-slip stopper 15 is located below the upper end of the guide rail 11 in the vertical direction.

[0028] The anti-slip stopper 15 can prevent the slider 13 from slipping out due to excessive movement on the guide rail 11 .

[0029] The lower side plate of the U-shaped mounting arm 3 is slidably connected to the frame 1 , and driving cylinders 16 are oppositely arranged on both sides of the supporting platform 2 on the frame 1 , and the movable ends of the driving cylinders 16 are connected to the bottom plate of the U-shaped mounting arm 3 .

[0030] The horizontal stop position of the U-shaped mounting arm 3 is adjusted by setting the driving cylinder 16, and the position of the vacuum suction cup is adjusted in cooperation with the lead screw driving member to adapt to the fixing point positions of different irregular workpieces, thereby improving the practicability of the device.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
