In this structure, the first driving motor and the second driving motor both adopt common servo motors or stepper motors on the market, and the first lifting and moving module and the first horizontal moving module both adopt common cylinders or electric cylinders on the market.

[0006] The third support seat includes a guide rail extending in the front-to-back direction, a slider slidingly matched with the guide rail, and two support blocks fixedly arranged on the upper end surface of the slider. The guide rail is fixedly arranged on the upper end surface of the mounting platform. The two support blocks are distributed in the front-to-back direction. The upper end surface of the support block is provided with a V-shaped groove extending in the left-to-right direction. The V-shaped groove runs through the left and right side surfaces of the support block. The first horizontal moving module is used to control the movement of the slider in the front-to-back direction. In this structure, the two support blocks are distributed in the front-to-back direction. The support block close to the feeding conveyor belt is used to place the screw to be processed, and the support block close to the unloading conveyor belt is used to place the processed screw, which is conducive to reducing the risk of mixing and has good reliability.

[0007] The mounting frame is provided with two guide holes, and the lower end surface of the mounting platform is fixed with two guide rods, and the two guide holes correspond to the two guide rods one by one, and the lower ends of the guide rods pass through the corresponding guide holes.

[0008] The mounting frame is provided with two positioning plates, and at least one of the positioning plates is provided with a pushing cylinder for pushing the screw. When the lifting mechanism lifts a screw, the pushing cylinder is located on the extension line of the screw. In this structure, since the position of the screw manually placed on the feeding conveyor belt is not fixed, when the screw on the feeding conveyor belt is lifted by the lifting mechanism, the end face of the screw is pushed by the pushing cylinder, so that the screw moves axially to the specified position, which is convenient for the transfer mechanism to grab the screw, and has good stability.

[0009] A lathe-milling composite processing production line using the above-mentioned screw conveying device includes a lathe, and a transfer mechanism is arranged on one side of the lathe, and the transfer mechanism is used to transfer the screw lifted by the lifting mechanism to the lathe or transfer the screw processed on the lathe to the lifting mechanism. In this structure, by setting the transfer mechanism to cooperate with the screw conveying device, the personnel only need to place the screw to be processed on the screw conveying device and remove the processed screw from the screw conveying device, and transfer the screw to be processed on the lifting mechanism to the lathe or transfer the screw processed on the lathe to the lifting mechanism through the transfer mechanism. The personnel have less workload and lower work intensity, which is conducive to improving the degree of automation; the transfer mechanism can adopt common mechanical slings on the market.

[0010] The transfer mechanism includes a bracket, a second horizontal moving module, a second lifting moving module and a clamp for clamping a screw. The second horizontal moving module is arranged on the bracket, the second lifting moving module can be moved in the horizontal direction and is arranged on one side of the second horizontal moving module, and the clamp can be moved in the up and down direction and is arranged at the lower end of the second lifting moving module. The second horizontal moving module and the second lifting moving module cooperate to control the clamp to reciprocate above the jacking mechanism and above the lathe.

[0011] Compared with the prior art, the advantage of the present invention is that the loading conveyor belt is used to convey the screw to be processed, and the unloading conveyor belt is used to convey the processed screw, thereby avoiding the risk of mixing of the screw to be processed and the processed screw being located on the same conveyor belt. At the same time, the screw on the loading conveyor belt is lifted upward by the jacking mechanism, which is convenient for cooperating with the transfer mechanism to grab the screw to be processed and transfer it to the lathe for processing. When the screw processing is completed, the transfer mechanism returns the processed screw to the jacking mechanism, and the jacking mechanism transfers the processed screw to the unloading conveyor belt. The jacking mechanism plays the role of intermediate transfer. Personnel only need to place the screw to be processed on the loading conveyor belt and remove the processed screw from the unloading conveyor belt. Compared with traditional tray-type material racks, it has a higher degree of automation, simple operation, is not easy to cause bumps, and has a lower production cost.
