[0002] A rotary screw driver is an automated tool used to quickly and accurately install screws into workpieces. It incorporates a rotational function that automatically adjusts the screw's direction during the installation process, ensuring accurate entry into the pre-set hole. Designed to improve production efficiency, reduce manual labor, and ensure consistent and accurate installation, this fixture is widely used on assembly lines in the electronics, automotive, and other industries, helping to improve product quality and reduce production costs. By reducing human error, rotary screw drivers provide important support for modern manufacturing.

[0003] During operation, the workpiece is placed in the fixture and fixed, and then the cutter head is lowered to allow the screw inside the cutter head to enter the preset screw hole of the workpiece. The screw is then threadedly connected to the workpiece through the self-rotation of the cutter head, completing the work. This helps reduce labor costs, improve production efficiency, and ensure product reliability and consistency.

[0036] The mounting assembly 3 includes a mounting plate 301, which is fixedly connected to the front bottom of the processing table 2.

The rear sides of the two right-angled trapezoidal blocks 305 are fixed. The cam 308 is fixedly connected to the cam 308, and the right-angled trapezoidal block 305 is connected to the cam 308. When the right-angled trapezoidal block 305 moves, the cam 308 can be driven to move synchronously in the same direction.

[0037] Reference Figure 5 - Figure 6The fixed component 5 includes a protective shell 508, which is rotatably connected to the top front side of the base 1. The protective shell 508 is used to protect the internal components. The right side of the protective shell 508 is fixedly connected to the electric telescopic rod 501, which is used to provide driving force. The electric telescopic rod 501 is a short-stroke electric telescopic rod, model La12. The left end of the electric telescopic rod 501 is fixedly connected to a moving block 502, which is fixedly connected to the telescopic end of the electric telescopic rod 501. The movement of the moving block 502 can be controlled by the electric telescopic rod 501. The front and rear sides of the moving block 502 are rotatably connected to L-shaped blocks 503. The two L-shaped blocks 503 are movably connected to a slider 504 at one end away from the moving block 502. The L-shaped block 503 is used to connect the moving block 502 and the slider 504. When the moving block 502 moves, the L-shaped block 503 can be moved. The two sliders 504 are provided with movable grooves 507 at the bottom, and the tops of the two sliders 504 are fixedly connected with splints 506, which are used to fix workpieces of different sizes. The two L-shaped blocks 503 are rotatably connected to the left and right sides of the interior of the protective shell 508, and the L-shaped block 503 is mainly connected to the protective shell 508 through a rotating shaft. The end of the L-shaped block 503 close to the slider 504 is movably connected to the inside of the movable groove 507. The movable groove 507 is mainly used to accommodate one end of the L-shaped block 503 to slide inside it, so as to control the movement of the slider 504. The internal top side of the protective shell 508 is fixedly connected to the limiting rod 505, and the two sliders 504 are slidably connected to the outer periphery of the limiting rod 505. The limiting rod 505 is used to further limit the sliding of the slider 504, so that the slider 504 can only move horizontally.

[0038] Reference Figure 4 The driving assembly 6 includes a wedge block 601, which is fixedly connected to one side of the isosceles trapezoidal block 304. Wedge grooves 602 are provided inside the two right-angled trapezoidal blocks 305. The two wedge blocks 601 are respectively slidably connected inside the two wedge grooves 602. The wedge grooves 602 are used to accommodate the sliding of the wedge blocks 601, so that the isosceles trapezoidal block 304 can stably control the movement of the right-angled trapezoidal block 305 when moving.

[0039] Working principle: When in use, first start the electric telescopic rod 501, which controls the moving block 502 to move to the left, so that the two L-shaped blocks 503 rotate in opposite directions. When the L-shaped block 503 rotates, it drives the slider 504 to move, and is limited by the limiting rod 505, so that the slider 504 can only move horizontally. Therefore, when the two L-shaped blocks 503 rotate in opposite directions, the two sliders 504 are controlled to move in opposite directions. Through the opposite movement of the two sliders 504, the two clamping plates 506 can be moved in opposite directions. After the distance between the two clamping plates 506 is increased, the workpiece can be placed between the two clamping plates 506. Then, the electric telescopic rod 501 is started again, so that the electric telescopic rod 501 controls the moving block 502 to move to the right. At this time, the two L-shaped blocks 503 rotate relative to each other, so that the two limiting rods 505 move toward each other to fix the workpiece.

[0040] Afterwards, according to the screw holes reserved on the workpiece, screws of corresponding sizes are selected, and by pressing the push block 302, the push rod 303 controls the movement of the isosceles trapezoidal block 304. When the isosceles trapezoidal block 304 moves, the two wedge blocks 601 will move accordingly in the two wedge grooves 602, and corresponding thrust will be applied to the two right-angled trapezoidal blocks 305, so that the two right-angled trapezoidal blocks 305 move along the two sliding rods 306 respectively and squeeze the spring 307. When the two right-angled trapezoidal blocks 305 move, the two connecting rods 308 will move together, so that the two clamping blocks 309 move in opposite directions, and then the top of the processing head 4 is inserted into the mounting plate 301. After that, the push block 302 can be released, and the return movement of the spring 307 makes the two right-angled trapezoidal blocks 305 move toward each other, so that the two clamping blocks 309 slide into the left and right ends of the top of the processing head 4 accordingly, so that the processing head 4 is fixed to the bottom of the mounting plate 301, and the installation is completed.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
