Description

Technical Field

[0001] This utility model relates to the field of thread processing equipment, and in particular to a processing equipment for irregular double-line trapezoidal threads. Background Technology

[0002] The non-standard double-start trapezoidal thread is a type of thread with two helical lines in a trapezoidal shape. This type of thread is typically used to transmit large torques and axial forces, offering high efficiency and reliability. Due to its unique trapezoidal profile, the non-standard double-start trapezoidal thread has wide applications in mechanical transmission, automotive, and aerospace fields. Compared to ordinary triangular threads, it offers better wear resistance and anti-slip properties, while also providing a smoother transmission effect. Existing non-standard double-start trapezoidal thread machining equipment generates a large amount of heat during the rotation of the tool and workpiece due to cutting friction. This heat causes the tool temperature to rise, reducing its hardness and wear resistance, necessitating tool replacement. Tool replacement is time-consuming and can also halt equipment processing, resulting in decreased production efficiency. Therefore, this invention proposes a non-standard double-start trapezoidal thread machining equipment. Utility Model Content

[0003] The purpose of this invention is to address the problem in the background technology that during the rotation of the cutting tool and the workpiece, a large amount of heat is generated due to the friction of cutting, which causes the tool temperature to rise.

However, replacing the tool takes a lot of time and also stops the equipment from processing, resulting in a decrease in production efficiency. The invention proposes a special-shaped double-line trapezoidal thread processing equipment.

[0028] As Figures 2 to 3As shown, the cutting assembly 7 includes a fixed plate 701, on which a fixed cylinder 702 is fixedly and through. The outer wall of the fixed cylinder 702 has multiple through slots 703 arranged in a circumferential array. A fixed block 704 is fixedly mounted on one side of the fixed plate 701, and a connecting rod 705 movably passes through the fixed block 704, guiding the connecting rod 705 to ensure stable movement. A threaded plate 706 is fixedly connected to the upper end of the connecting rod 705, with the threaded surface of the threaded plate 706 being inclined. An internal threaded ring 707 is threadedly fitted onto the outer wall of the threaded plate 706, with the inner wall of the internal threaded ring 707 also inclined, allowing it to push the threaded plate 706 during rotation. 6. The lower end of the linkage 705 is fixedly connected to a connecting block 708. The bottom surface of the connecting block 708 has a first slot 709. A second slot 710 is slidably arranged inside the first slot 709. A cutting blade 711 is fixedly connected to the lower end of the second slot 710, which facilitates the disassembly and replacement of the cutting blade 711 and improves production efficiency. The cutting blade 711 is movably connected to the through slot 703, which can guide the cutting blade 711. A spring 712 is sleeved on the outer wall of the linkage 705. One end of the spring 712 is fixedly connected to the fixing block 704, and the other end of the spring 712 is fixedly connected to the connecting block 708, which can provide support for the threaded plate 706, thereby preventing it from disengaging from the internal threaded ring 707.

[0029] like Figure 1 and Figure 5 As shown, the positioning component 8 includes a second cylinder 81 fixedly mounted on the upper surface of the processing table 1. The output end of the second cylinder 81 is fixedly connected to a motor 82. The output end of the motor 82 is fixedly mounted with a fixed plate 83, which can drive the fixed plate 83 to rotate.

[0030] Furthermore, guide grooves 9 are respectively provided on both sides of the inner wall of the frame 5, and guide blocks 10 are respectively fixed on both sides of the fixed plate 701. The guide blocks 10 are slidably connected to the guide grooves 9, which can stabilize the fixed plate 701 and make the fixed plate 701 move vertically and stably.

[0031] Secondly, the inner wall of the through groove 703 is provided with symmetrical sliding grooves 11, and sliders 12 are fixedly installed on both sides of the outer wall of the cutting tool 711.

[0033] The working principle of this embodiment is as follows: Place the workpiece between the clamping blocks 85 and start the electric push rod 84. The output end of the electric push rod 84 pushes the clamping blocks 85 to move, so as to stably clamp the workpiece. Subsequently, set various data of the thread processing through the numerical control component 4. The numerical control component 4 starts the second cylinder 81. The output end of the second cylinder 81 pushes the motor 82 to move horizontally. The motor 82 drives the electric push rod 84 and the clamping blocks 85 on the fixed disk 83 to move horizontally, so as to push the workpiece to move horizontally into the cutting component 7. During the horizontal movement of the workpiece, start the motor 82. The output end of the motor 82 drives the fixed disk 83 to rotate. The fixed disk 83 drives the electric push rod 84 and the clamping blocks 85 to rotate, so that the workpiece clamped between the clamping blocks 85 rotates and moves horizontally into the fixed cylinder 702.

[0034] Manually rotate the internal thread ring 707 through the anti-slip groove 13. The internal thread ring 707 is threadedly connected to the thread piece 706, so that the internal thread ring 707 pushes the thread piece 706 to move. The thread piece 706 drives the linkage rod 705 to move on the fixed block 704. The linkage rod 705 drives the connecting block 708 to move. Through the cooperation of the first card slot 709 and the second card slot 710, the connecting block 708 makes the cutting tool 711 move. After the tool is worn, the contact pressure between the tool and the workpiece can be quickly adjusted, which can ensure the precise cooperation between the tool and the workpiece during the processing, thereby improving the processing accuracy of the thread, increasing the service life of the tool, and eliminating the need for frequent tool replacement, and enhancing the efficiency of thread processing.

[0035] After the workpiece moves horizontally into the fixed cylinder 702, the workpiece rotates and comes into rotational contact with the cutting head of the cutting tool 711 during the rotation process, so as to cut threads on the surface of the workpiece.

[0036] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
