Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thread processing equipment, in particular to a belt-driven thread processing equipment. Background Art
[0002] Thread machining is a process that uses tools for making threads to process workpieces through processes such as cutting, turning, milling, and grinding. It generally refers to the method of using forming tools or grinding tools to process threads on workpieces. The main methods include turning, milling, tapping, threading, grinding, lapping, and whirling cutting. When turning, milling, and grinding threads, the machine tool's transmission chain ensures that the turning tool, milling cutter, or grinding wheel moves one lead accurately and evenly along the axial direction of the workpiece for each rotation of the workpiece. When machining the internal thread of a nut, the grinding tool will rotate relative to the nut, and the previously formed thread groove will guide the grinding tool to move axially.
[0003] When machining the internal thread of a nut, the nut to be machined is often fixed in front of a mold. After machining is completed, the nut needs to be manually replaced in front of the mold, which is extremely inconvenient and dangerous.
[0004] An existing patent (publication number: CN217142598U) discloses a thread processing device. This utility model is equipped with a conversion mechanism. When replacing a nut, the placement disk can be directly rotated to avoid the need to operate the nut directly in front of the thread processing rod to avoid danger. The thread processing mechanism can be used to process the thread inside the nut. The three sections of threads of different specifications on the surface of the thread processing rod are used to finally grind out a nut with a thread groove that meets the requirements.
[0005] In response to the above problems, existing patents have provided solutions, but the existing thread processing equipment only uses a motor to drive a pulley, which in turn drives a pulley connected to the triangular chuck to rotate through a belt, so that the triangular chuck can carry the workpiece to rotate. However, because the surface of the pulley and the inner side of the belt are both smooth, the friction between them is relatively small and not stable enough. During the transmission operation, due to the instability of the friction, the belt may slip on the pulley, resulting in unstable rotation control and low transmission accuracy. This method is only suitable for some ordinary thread processing that does not require extremely high internal thread processing accuracy, and cannot meet the needs of internal thread processing of high-quality workpieces.
[0006] Therefore, a belt-driven thread processing device is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] See also Figure 1-6 , this utility model provides a technical solution:

[0032] The transmission mechanism 6 includes a motor 601 arranged on the rear side of the shell box 5, and a cam wheel 602 is rotatably connected to the rear side of the left side of the shell box 5. The right side of the cam wheel 602 is bolted to the output end of the motor 601. A fixed sleeve 603 is provided inside the left side of the shell box 5, and an empty tube 604 is rotatably connected inside the fixed sleeve 603. The right side of the empty tube 604 is bolted to the chuck 7. A cam 605 is provided on the outside of the empty tube 604.

[0033] In this embodiment, by providing a transmission mechanism 6, the concave-convex groove 607 on the inner side of the transmission belt 606 engages with the cam 605 and the concave wheel 602, greatly increasing friction and effectively preventing the transmission belt 606 from slipping. This design ensures that the chuck 7 can stably carry the workpiece for rotation, significantly improving transmission accuracy and stability. For high-precision thread processing requirements, such as internal thread processing of high-quality workpieces such as aerospace parts and precision instruments, this equipment can provide reliable protection, reduce processing errors caused by slippage of the transmission belt 606 and unstable transmission, improve the dimensional accuracy and surface quality of the thread, and better meet the strict requirements of various industrial fields for thread quality. Secondly, the adjustment structure 3 provided at the bottom of the frame 4 can flexibly adjust the processing position of the housing 5, transmission mechanism 6, and chuck 7 on the top of the frame 4, which greatly improves the convenience of processing.

[0037] In this embodiment: by setting up a blowing mechanism 9, impurities such as chips will be generated during the thread processing process. Gas is transported through the air pipe 901, and is blown out from the blow pipe 903 after adjustment by the control valve 902, so as to clean the impurities inside the empty pipe 604 and the processing area of the chuck 7 in time, ensuring the cleanliness of the processing environment, which is conducive to improving the processing accuracy and reducing equipment wear.
[0038] Specifically, such as Figure 4 As shown, the positioning structure 3 includes slide rails 301 bolted to both sides of the top of the support 2 , the outer side of the slide rails 301 is slidably connected to a slide sleeve 302 , and the top of the slide sleeve 302 is bolted to the bottom of the frame plate 4 .

[0040] In this embodiment: by setting the adjustment structure 3, the adjustment block 305 can be driven to move by adjusting the screw rod 304 according to the size and processing requirements of different workpieces, and then the sliding sleeve 302 can slide on the sliding rail 301, and the shell box 5, transmission mechanism 6 and chuck 7 on the top of the frame plate 4 can be flexibly adjusted to adjust the processing position, which greatly improves the convenience and adaptability of processing.
[0041] Specifically, such as Figure 5 As shown, the engraving structure 8 includes a lifting frame 801 bolted to the right side of the top of the machine 1, and a driver 802 is provided on the front side of the lifting frame 801.
[0042] Specifically, such as Figure 5 As shown, a rotating rod 803 is provided on the front side of the driver 802 , and an internal thread processing cutter 804 is provided on the outer side of the rotating rod 803 .
[0043] In this embodiment: by setting the engraving structure 8, the driver 802 drives the rotating rod 803 to drive the internal thread processing tool 804 to rotate, and the lifting frame 801 can be used to adjust the height of the internal thread processing tool 804 to achieve internal thread processing of the workpiece, thereby improving processing efficiency and accuracy.

By setting up a limit plate 12, the limit plate 12 plays a limiting role on the adjustment block 305, preventing the adjustment block 305 from excessive movement on the screw rod 304.
[0047] Working principle: During the use of the belt-driven thread processing equipment, the motor 601 is started, and the output end of the motor 601 drives the cam 602 to rotate. Since the concave and convex grooves 607 on the inner side of the transmission belt 606 are respectively engaged with the cam 602 and the cam 605, the rotation of the cam 602 drives the cam 605 to rotate through the transmission belt 606, and the rotation of the cam 605 drives the empty tube 604 to rotate. The empty tube 604 is bolted to the chuck 7, so that the chuck 7 can stably carry the workpiece for rotation. At the same time, the lifting frame 801 in the engraving structure 8 adjusts the height of the driver 802, and then the driver 802 drives the rotating rod 803 to rotate, and the internal thread processing cutter 804 on the outer side of the rotating rod 803 rotates accordingly, so that it contacts the workpiece on the chuck 7 to perform internal thread processing. During the processing, the gas pipe 901 transports gas, and the gas is passed through the control valve 9 02 After adjustment, the gas is blown out from the blowpipe 903. The right side of the bottom of the blowpipe 903 is located inside the empty pipe 604 and the processing area of the chuck 7. The chips and other impurities generated during the processing are cleaned in time to ensure the cleanliness of the processing environment. The collecting box 10 is located at the bottom of the chuck 7, which can collect the chips and waste generated during the thread processing. The anti-wear pad 11 reduces the wear of the chips on the collecting box 10 and extends the service life of the collecting box 10. Before this, by rotating the screw rod 304, the adjusting block 305 is moved on the screw rod 304, and the top of the adjusting block 305 is bolted to the bottom of the frame plate 4, thereby driving the sliding sleeve 302 to slide on the slide rail 301, realizing flexible adjustment of the processing position of the shell box 5 on the top of the frame plate 4 and the chuck 7 and other structures. The overall coordination provides a solid foundation for thread processing and meets the strict requirements of thread processing in different industrial fields.
[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
