[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-8 As shown, a screw positioning device for machining screws includes a thread processing machine body 1. Guide posts 2 are fixedly connected to both sides inside the thread processing machine body 1. A slider 3 is slidably connected to the surface of the guide posts 2. A positioning housing 4 is fixedly connected to the bottom of the slider 3. Several connecting parts 7 are slidably connected inside the positioning housing 4. A positioning block 5 is fixedly connected to one end of each connecting part 7. A spring structure 9 is provided inside each connecting part 7 to assist in the ejection of the connecting part 7 from the positioning block 5. The spring structure 9 includes a spring guide rod 91 disposed inside the connecting part 7, with the top end of the spring guide rod 91 fixedly connected to the inside of the positioning housing 4. A spring 92 is sleeved on the surface of the spring guide rod 91, with both ends of the spring 92 fixed to the positioning housing 4 and the inner wall of the connecting part 7, respectively. The structure 9 is designed so that when the connecting piece 7 and the positioning block 5 are needed to position the screw, the connecting piece 7 and the positioning block 5 can be popped outward by the internal spring 92, which facilitates the measurement of the screw position. The bottom of the front side of the positioning housing 4 is fixedly connected to the fixing block 12, the top of the fixing block 12 is fixedly connected to the electric push rod 13, the top of the electric push rod 13 is fixedly connected to the support plate 14, and a small handle 10 is fixedly connected to one side of the positioning block 5. With the setting of the small handle 10, when the positioning block 5 needs to be stored, it can be pulled into the positioning housing 4 through the small handle 10, so that the connecting piece 7 can be retracted into the positioning housing 4, thereby reducing the difficulty of operation for the operator. On the left and right sides of one side of the positioning housing 4, there are fine adjustment structures 11 for fine adjustment of the unprocessed screw.

[0025] The fine-tuning structure 11 includes two connecting blocks 112 fixedly connected to one side of the positioning housing 4 and a threaded rod 113 threadedly connected inside the connecting blocks 112. One end of the threaded rod 113 is fixedly connected to a knob 111 for assisting in rotating the threaded rod 113, and the other end of the threaded rod 113 is fixedly connected to a rubber pad 114. With the setting of the fine-tuning structure 11, when the screw position is inaccurate, the screw can be driven to make fine adjustments up and down and left and right by the cooperation of the electric push rod 13, the connecting blocks 112, the threaded rod 113, the knob 111 and the rubber pad 114, thereby reducing the difficulty of operation for workers and improving work efficiency.

[0026] A pointer 8 is fixedly connected to one side of the protruding connecting plate at the top of the connector 7. Several scales 15 are provided on both the front and rear sides of the positioning housing 4, and the scales 15 can be used in conjunction with the pointer 8. By observing the scales on the pointer 8 and the scales 15, the position of the screw can be determined, thus facilitating subsequent adjustment of the screw position. This reduces the difficulty of storage and improves work efficiency.

[0027] The positioning housing 4 has several limiting blocks 6 rotatably connected inside, and the limiting blocks 6 cooperate with the connecting plate protruding from the top of the connecting piece 7. The other end of the limiting block 6 is fixedly connected with a pressure plate 16. Through the cooperation of the limiting block 6 and the pressure plate 16, the connecting piece 7 that is stored inside the positioning housing 4 can be fixed, so that the positioning block 5 will not pop out randomly when not in use.

[0028] It is worth noting that the technical features of the thread processing machine body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, control method and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0029] Working principle: When positioning an unprocessed screw, first fix one end of the screw to the three-jaw chuck on one side of the thread processing machine body 1. Then, push the tapered fastener through the hydraulic rod at the other end to make contact with the other end of the screw. Next, the slider 3 can be driven to slide to the left on the surface of the guide post 2, so that the positioning housing 4 is located on the surface of the screw. Then, the pressure plate 16 set inside the positioning housing 4 can be moved to drive the limit block 6 to remove the limit on the connecting piece 7. Because there is no limit on the limit block 6, the connecting piece 7 will be subjected to the elastic force of the spring 92 in the spring structure 9, thereby driving the connecting piece 7 and the positioning block 5 to move towards the surface of the screw. When the connecting piece 7 moves the positioning block 5 to fit against the surface of the screw, the position of the screw can be determined by observing the pointer 8 and the scale 15 on one side. When the unprocessed screw is tilted vertically, the electric push rod 13 can be activated to make fine adjustments vertically. When the unprocessed screw is tilted horizontally, the knob 111 can be rotated to make the threaded rod 113 and the rubber pad 114 move the unprocessed screw horizontally, thereby completing the fine adjustment of the unprocessed screw horizontally. When the data of the pointers 8 and the scale 15 on the positioning housing 4 are the same, the positioning of the unprocessed screw is completed, so as to facilitate better subsequent processing.
