Description
Technical Field
[0001] This utility model relates to the field of thread rolling machine technology, specifically to a screw positioning mechanism for a thread rolling machine. Background Technology
[0002] In the field of machining, thread rolling machines are indispensable key equipment for producing screws, bolts, nuts and other fasteners. Their core function is to process threads that meet standard specifications on the surface of these parts through high-precision machining processes, thereby giving the fasteners the ability to reliably connect and fix other mechanical components. The quality of the threads directly affects the performance of the fasteners, including their tensile strength, shear strength and reliability in different environments. Therefore, thread rolling machines play a vital role in ensuring the stability and safety of mechanical assemblies.
[0003] Traditional thread rolling machines typically rely on complex mechanical positioning devices for screw positioning. These devices often require operators to manually adjust the screw's position to ensure stability and accuracy during the thread rolling process. For example, some machines require operators to use clamps or positioning pins to fix the screw, which not only increases the complexity of operation but also easily leads to inaccurate positioning due to human factors. Such inaccurate positioning directly affects the quality of thread rolling, resulting in uneven thread processing or defects, which in turn affects the overall performance and service life of the product. In the unloading stage, traditional thread rolling machines also suffer from low efficiency. The processed screws usually need to be manually removed one by one by the operator. This process is not only time-consuming and labor-intensive but also easily causes scratches or damage to the screw surface due to frequent manual operation. For example, in some small factories, operators need to repeat this action for a long time in high-temperature and noisy environments, which not only increases labor intensity but may also lead to operator fatigue, further reducing production efficiency. Utility Model Content
[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a screw positioning mechanism for a thread rolling machine, which solves the technical problems in related technologies / prior technologies where screw positioning usually relies on complex mechanical positioning devices and manual feeding increases labor intensity.
[0005] The system includes a processing base, a thread rolling plate 1 fixedly connected to the upper surface of the processing base, a hydraulic cylinder provided on the upper surface of the processing base, a piston rod fixedly connected to the output end of the hydraulic cylinder, a transmission plate fixedly connected to the surface of the piston rod, a guide slider fixedly connected to the surface of the transmission plate, a second thread rolling plate fixedly connected to the surface of the transmission plate, a positioning sleeve fixedly connected to the surface of the second thread rolling plate, a placement hole provided on the surface of the positioning sleeve, a screw body provided inside the placement hole, a right-angle bracket fixedly connected to the upper surface of the processing base, a mounting frame provided on the surface of the right-angle bracket, an electromagnet provided inside the mounting frame, and a collection cavity provided on the surface of the processing base.
[0006] The above technical solution provides a simple and convenient positioning method, which can effectively ensure that the screw body is accurately located in the middle of the two thread rolling plates. This avoids the traditionally complicated positioning steps and improves work efficiency. The electromagnet attracts the screw body after thread rolling and makes it fall into the collection chamber automatically, reducing the workload of manually removing the screw and further improving the convenience of operation. It provides personnel with an accurate positioning position to ensure that subsequent thread rolling work can proceed normally.
[0007] As a further improvement to the above solution, the placement hole and the screw body are adapted to each other, and the upper surface of the screw body overlaps the surface of the positioning sleeve plate.
[0008] As a further improvement to the above solution, the surface of the right-angle frame is provided with a control panel, and the control panel is electrically connected to the electromagnet.
[0009] As a further improvement to the above solution, a connecting rod is fixedly connected to the surface of the right-angle frame, and the bottom end of the connecting rod is fixedly connected to the upper surface of the mounting frame.
[0010] As a further improvement to the above solution, a pad is fixedly connected to the upper surface of the processing base, and the pad is fixedly connected to the lower surface of the hydraulic cylinder.
[0011] As a further improvement to the above solution, a guide groove is provided on the upper surface of the processing base, and the guide slider is slidably connected inside the guide groove.
[0012] As a further improvement to the above solution, the electromagnet is located above the collection chamber, and the thread rolling plate is slidably connected to the upper surface of the processing base through a guide slider, ensuring that the screw body can fall smoothly into the collection chamber after the electromagnet is turned off, thereby improving the collection efficiency.
[0013] As a further improvement to the above solution, the guide slider and the guide groove are adapted to each other, and the placement hole is located in the middle of the first thread rolling plate and the second thread rolling plate.
[0014] The beneficial effects of this utility model are as follows: This invention achieves rapid and accurate screw positioning by matching the placement hole on the positioning sleeve with the screw body and overlapping the upper surface of the screw body with the positioning sleeve. This avoids the traditional complex positioning steps, allowing personnel to quickly place the screw in place, significantly improving positioning efficiency and providing an accurate initial position for the subsequent thread rolling process, ensuring thread rolling quality. At the same time, the magnetic attraction of the electromagnet is used to achieve material feeding. After the screw is threaded, the electromagnet attracts the screw, causing it to rise and detach from the placement hole. Then, the electromagnet is turned off, and the screw automatically falls into the collection chamber. This process avoids the tedious operation of manually removing screws one by one, reducing manual intervention and labor intensity. Attached Figure Description

[0023] like Figures 1-4As shown, this invention illustrates a screw positioning mechanism for a thread rolling machine according to an embodiment of the present invention. The mechanism includes a processing base 1, a thread rolling plate 2 fixedly connected to the upper surface of the processing base 1, a hydraulic cylinder 3 mounted on the upper surface of the processing base 1, a piston rod 4 fixedly connected to the output end of the hydraulic cylinder 3, a transmission plate 5 fixedly connected to the surface of the piston rod 4, a guide slider 6 fixedly connected to the surface of the transmission plate 5, a second thread rolling plate 7 fixedly connected to the surface of the transmission plate 5, a positioning sleeve 8 fixedly connected to the surface of the second thread rolling plate 7, a placement hole 9 on the surface of the positioning sleeve 8, a screw body 10 disposed inside the placement hole 9, a right-angle bracket 11 fixedly connected to the upper surface of the processing base 1, a mounting frame 12 disposed on the surface of the right-angle bracket 11, an electromagnet 13 disposed inside the mounting frame 12, and a collection cavity 14 on the surface of the processing base 1.
[0024] In this embodiment, the operator places the screw body 10 to be thread-rolled into the placement hole 9 on the surface of the positioning sleeve plate 8, ensuring that the part of the screw body 10 to be thread-rolled is located in the middle of the thread-rolling plate 2 and the thread-rolling plate 7. The hydraulic cylinder 3 is activated, and the hydraulic cylinder 3 drives the transmission plate 5 and the guide slider 6 to move linearly along the upper surface of the processing base 1 through the piston rod 4, thereby causing the thread-rolling plate 7 to move linearly. During the linear movement of the thread-rolling plate 7, the screw body 10 moves accordingly and is thread-rolled by the thread-rolling plate 2 and the thread-rolling plate 7. After the thread-rolling is completed, the screw body 10 is disengaged. When the thread rolling plate 2 is removed from the surface, the electromagnet 13 is activated. The electromagnet 13 generates magnetic force to attract the screw body 10 after thread rolling and make it rise and detach from the placement hole 9. Then, the hydraulic cylinder 3 drives the piston rod 4 to retract, causing the thread rolling plate 7 to slide back to its original position, and driving the positioning sleeve 8 to reset again. When the thread rolling plate 7 resets, the electromagnet 13 is turned off, and the screw body 10 is no longer attracted by magnetic force and automatically falls downward into the collection chamber 14. After resetting to the initial state, the operator can put a new screw into the placement hole 9 on the surface of the positioning sleeve 8 for quick positioning and continue the thread rolling operation.
[0025] See in some examples Figure 3 The placement hole 9 and the screw body 10 are adapted to each other, and the upper surface of the screw body 10 overlaps the surface of the positioning sleeve plate 8.
[0026] Furthermore, a control panel 15 is provided on the surface of the right-angle bracket 11. The control panel 15 is electrically connected to the electromagnet 13. The control panel 15 can be used to easily control the opening and closing of the electromagnet 13, thereby realizing the adsorption and release operation of the screw body 10 after thread rolling.
[0027] refer to Figure 3 A pad 17 is fixedly connected to the upper surface of the processing base 1, and the pad 17 is fixedly connected to the lower surface of the hydraulic cylinder 3.
[0028] Furthermore, a connecting rod 16 is fixedly connected to the surface of the right-angle frame 11, and the bottom end of the connecting rod 16 is fixedly connected to the upper surface of the mounting frame 12.
[0029] Furthermore, a guide groove 18 is provided on the upper surface of the processing base 1, and the guide slider 6 is slidably connected inside the guide groove 18. When the hydraulic cylinder 3 drives the piston rod 4 to move, the transmission plate 5 and the guide slider 6 move linearly along the upper surface of the processing base 1. The guide slider 6 slides in the guide groove 18, which guides the movement of the transmission plate 5 and the thread rolling plate 7, ensuring the accuracy and stability of their movement direction.
[0030] like Figure 4 As shown, on the other hand, this utility model also provides a screw positioning mechanism for a thread rolling machine. The electromagnet 13 is located above the collecting chamber 14, and the thread rolling plate 7 is slidably connected to the upper surface of the processing base 1 via the guide slider 6. When the electromagnet 13 is closed, the attracted screw body 10 can fall down smoothly and automatically into the collecting chamber 14. At the same time, the thread rolling plate 7 is slidably connected to the upper surface of the processing base 1 via the guide slider 6. This connection method allows the thread rolling plate 7 to slide smoothly on the processing base 1, ensuring its smooth movement.
[0031] Furthermore, the guide slider 6 and the guide groove 18 are adapted to each other, and the placement hole 9 is located in the middle of the thread rolling plate 2 and the thread rolling plate 7.
[0032] In this embodiment, firstly, the operator precisely places the screw body 10 to be threaded into the placement hole 9 on the surface of the positioning sleeve 8. Since the placement hole 9 and the screw body 10 are compatible, and the upper surface of the screw body 10 overlaps the surface of the positioning sleeve 8, this ensures that the screw body 10 can be stably placed on the positioning sleeve 8. At the same time, the part that needs to be threaded is located exactly in the middle of the thread rolling plate 2 and the thread rolling plate 7, providing an accurate initial position for the subsequent thread rolling operation. Then, the hydraulic cylinder 3 is activated. The output end of the hydraulic cylinder 3 drives the transmission plate 5 and the guide slide fixedly connected to the surface of the transmission plate 5 through the piston rod 4. Block 6 moves linearly along the upper surface of the processing base 1. During the movement, the guide slider 6 slides in the guide groove 18 on the upper surface of the processing base 1. This guide structure effectively ensures the accuracy and stability of the movement direction of the transmission plate 5 and the thread rolling plate 7, avoiding deviation or shaking during the movement. This allows the thread rolling plate 7 to move smoothly in a straight line. As the thread rolling plate 7 moves in a straight line, the positioning sleeve 8 fixedly connected to its surface and the screw body 10 in the placement hole 9 also move. During the movement, the screw body 10 is threaded by the thread rolling plate 2 and the thread rolling plate 7, completing the thread rolling process of the screw.
[0033] After the thread rolling operation is completed, the screw body 10 detaches from the surface of the thread rolling plate 2. At this time, the electromagnet 13 installed in the mounting frame 12 on the surface of the right-angle bracket 11 is activated. The electromagnet 13 generates magnetic force to attract the thread-rolled screw body 10 and make it rise, so that it detaches from the placement hole 9. The opening and closing of the electromagnet 13 is controlled by the control panel 15 set on the surface of the right-angle bracket 11. The operator can easily operate the electromagnet 13 through the control panel 15, thereby realizing the attraction and release of the thread-rolled screw body 10. While the electromagnet 13 attracts the screw body 10 and makes it rise, the hydraulic cylinder 3 drives the piston rod 4 to retract, so that the thread rolling plate 7 slides back to its original position, and drives the positioning sleeve 8 to return to its initial position. When the thread rolling plate 7 returns to its original position, the electromagnet 13 is turned off. At this time, the screw body 10 is no longer attracted by magnetic force and falls down automatically. Since the electromagnet 13 is located above the collection chamber 14, the screw body 10 can fall smoothly and automatically into the collection chamber 14, completing the screw collection work.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
