[0002] With the booming development of the manufacturing industry, the demand for screws, as a basic and key fastening component, has exploded in various fields. Among the many screw production processes, rotary forming has become one of the mainstream screw manufacturing methods due to its advantages of high efficiency and high precision, which makes the importance of rotary forming screw machines increasingly prominent.

[0003] However, existing screw-making machines are not convenient for fixing the screws to be screwed at the discharge port during use. During the production process, factors such as vibration and movement of the equipment may cause the screws to shift or fall off, which may affect product quality or even damage the equipment. Summary of the Invention

[0004] The purpose of this utility model is to provide a rotary pressing screw machine. By setting a self-locking feeding mechanism, it solves the problem that existing screw machines are not convenient to fix the screws to be tightened at the discharge port during use, and that during the production process, factors such as vibration and movement of the equipment may cause the screws to shift or fall off, thereby affecting product quality or even damaging the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a rotary pressing screw machine, which includes two support legs, and the two support legs are provided with a self-locking feeding mechanism and a pressing and rotating mechanism. The self-locking feeding mechanism includes a self-locking mechanism and a feeding mechanism. The self-locking mechanism includes a pipe disposed above the support leg. A ring is fixedly connected to the bottom of the pipe. Two limiting blocks are rotatably connected to the outer wall of the ring. Rubber rings are fixedly connected to the two limiting blocks. A groove is formed at the bottom of the pipe. The feeding mechanism includes a feeding pipe disposed on the right side of the pipe. The bottom of the feeding pipe extends into the pipe. The bottom extension of the feeding pipe contacts the pipe. The feeding pipe is hinged to the pipe. A hinge block is fixedly connected to the left side of the feeding pipe. A cylindrical rod is hinged to the left side of the hinge block. A cylindrical box is slidably connected to the left side of the cylindrical rod. A spring is fixedly connected to the left side of the cylindrical rod. The left side of the spring is fixedly connected to the cylindrical box.

[0006] Furthermore, a second hinge block is fixedly connected to the left side of the cylindrical box, and the second hinge block is hinged to the pipe.

[0007] Furthermore, a workbench is fixedly connected between the two support legs, and a plurality of limiting blocks are fixedly connected to the top of the workbench.

[0008] Furthermore, two support rods are fixedly connected to the top of the workbench, and a rectangular plate is fixedly connected to the top of the two support rods.

[0009] Furthermore, the downward rotating mechanism includes a limiting box fixedly connected to the rectangular plate, and a hydraulic cylinder is fixedly connected to the top of the inner wall of the limiting box.

[0010] Furthermore, the output shaft of the hydraulic cylinder is fixedly connected to a motor housing, and a motor is connected to the inner wall of the motor housing.

[0011] Furthermore, a rotating shaft is provided inside the pipe, the outer wall of the rotating shaft is in contact with the pipe, and the output shaft of the motor passes through it; a coupling is fixedly connected to the rotating shaft, and a screwdriver head is fixedly connected to the bottom of the rotating shaft.

[0012] This utility model has the following beneficial effects: 1. By setting a self-locking feeding mechanism, after placing the part to be screwed between the four limit blocks 1 on the worktable, the screw is placed in the pipe. The screw will slide into the pipe with gravity and then be stuck between two limit blocks 2. The hydraulic cylinder is opened to stretch it. The hydraulic cylinder drives the rotating shaft to descend, and the rotating shaft drives the screwdriver head to descend. After a period of time, until the screwdriver head attracts the screw, the screwdriver head continues to descend. The screw will squeeze the two limit blocks 2, causing the two limit blocks 2 to move away from each other. The rubber ring is stretched, allowing the screw and screwdriver head to pass between the two limit blocks 2. The screwdriver head will push open the feed pipe. At this time, the feed pipe will rotate. The top of the feed pipe will squeeze the cylindrical rod, causing the cylindrical rod to squeeze the spring, compressing the spring, so that the screw can be fixed at the outlet. This avoids the screw from being displaced or falling off due to vibration or movement of the equipment, which would affect product quality or even damage the equipment. 2. By setting up a downward rotating mechanism, the part to be screwed is placed between the four limit blocks on the worktable, with the threaded hole aligned with the bottom of the screwdriver head. The hydraulic cylinder, through the transmission of the parts below, drives the screwdriver head to contact and attract the screw. After the screw enters the threaded hole, the motor in the motor box is turned on. The motor drives the screwdriver head to rotate through the shaft, and the screwdriver head drives the screw into the threaded hole. At this time, the motor is turned off, and the hydraulic cylinder is controlled to retract, thereby driving the shaft and screwdriver head to reset. During this process, the rubber ring will drive the two limit blocks to reset, and the spring will drive the feed tube to reset, preparing for the next screw tightening. This enables automatic screw tightening, eliminating the need for workers to perform tedious screw tightening work, which not only reduces the labor intensity of workers but also improves the assembly quality and stability of the product.

The motor 314 drives the rotating shaft 315 to descend, and the rotating shaft 315 drives the screwdriver head 316 to descend. During this process, the screwdriver head 316 will push open the feed pipe 221. At this time, the feed pipe 221 will rotate, and the top of the feed pipe 221 will press against the cylindrical rod 223, causing the cylindrical rod 223 to be compressed. Spring 225 is compressed, causing screwdriver head 316 to continue descending until it attracts the screw. As screwdriver head 316 continues to descend, the screw will press against the two limit blocks 213, causing them to move away from each other. Rubber ring 214 is stretched, allowing the screw and screwdriver head 316 to pass between the two limit blocks 213. After the screw enters the threaded hole, motor 314 in motor box 313 is turned on. Motor 314 drives screwdriver head 316 to rotate via shaft 315, and screwdriver head 316 drives the screw into the threaded hole. At this time, motor 314 is turned off, and hydraulic cylinder 312 is controlled to retract, thereby driving shaft 315 and screwdriver head 316 to reset. During this process, rubber ring 214 will drive the two limit blocks 213 to reset, and spring 225 will drive feed tube 221 to reset, preparing for the next screw tightening.
