Description

Technical Field

[0001] This utility model belongs to the technical field of vortex milling devices, specifically relating to a transmission worm gear vortex milling device. Background Technology

[0002] Whirl milling is a high-speed thread milling device used with ordinary lathes. It's a thread machining method that uses a carbide forming cutter mounted on a high-speed rotating cutter head to mill threads from a workpiece. Due to its high milling speed (up to 400 m / min), it has high machining efficiency and uses compressed air for chip removal and cooling. The cutting debris, resembling a whirlwind, is used during the machining process, hence the name "whirl milling." Whirl milling can achieve dry cutting, heavy-duty cutting, machining of difficult-to-machine materials, and ultra-high-speed cutting, while consuming little power. Surface roughness can reach Ra 0.8 μm. Because the lathe spindle speed is slow, the machine tool has high motion accuracy and good dynamic stability, making it an advanced thread machining method. The internal whirl milling cutter head encloses the workpiece during cutting. Due to the long envelope stroke of the whirl milling cutter during cutting, the cutting volume is large, and the cutting force is relatively higher than that of external cutting whirl milling, resulting in higher efficiency and a higher surface finish. Therefore, internal whirl milling is suitable for thread precision machining.

[0003] Application number "CN201922306879.3" describes "a transmission worm gear cyclone milling device, including a fixed base, a fixed disk, and a cutter head. A central sleeve is welded to the center of the front surface of the fixed disk. The cutter head is sleeved and fixed on the outside of the central sleeve on the front surface of the fixed disk. A first bearing is sleeved at the connection between the cutter head and the central sleeve. A gear ring is provided on the outer wall of the cutter head. A worm is provided on the front surface of the fixed disk above the cutter head. Second bearings are sleeved at both ends of the worm along its length and are welded and fixed to the fixed disk. The worm meshes with the gear ring."

[0004] The aforementioned patent features two worm gears symmetrically arranged at the upper and lower ends of the cutter head on the fixed disc, meshing with gear rings on the outer side of the cutter head. The cutter head is rotated by the worm gears. This transmission method overcomes the shortcomings of traditional belt drives, enabling high power transmission without overload slippage or unstable transmission. However, the cutter head will wear down after prolonged use. Continued use can easily reduce the accuracy of cyclone milling, and the metal fragments milled by cyclone milling cannot be collected in a centralized manner, requiring manual collection by the staff, thus increasing the labor intensity of the staff.

[0036] A worm gear cyclone milling device comprises a fixed circular base 1, a machining mechanism, a support rod 12, and a collecting mechanism, as described in detail below:

[0037] Please see Figure 1 The machining mechanism is located on the fixed round seat 1, which is used to facilitate the disassembly and replacement of the cutter head of the cyclone milling machine. Specifically, the machining mechanism also includes: a rotating component located on the fixed round seat 1. Specifically, the rotating component includes a rotating groove 2, which is opened on the inner wall of the fixed round seat 1. Two rotating blocks 3 are symmetrically arranged on the inner wall of the rotating groove 2. A rotating round seat 4 is welded between the two rotating blocks 3, which effectively controls the rotating round seat 4 to rotate the worm gear normally.

[0038] Please see Figure 2 The disassembly assembly is located on the fixed round seat 1 and works in conjunction with the rotating assembly. Specifically, the disassembly assembly includes two symmetrically arranged T-shaped slides 5. The two T-shaped slides 5 are opened on the outer side wall of the rotating round seat 4. T-shaped sliders 6 are slidably arranged on the inner wall of the T-shaped slides 5. A cyclone milling cutter body 7 is welded between the two T-shaped sliders 6.

[0039] In this embodiment: by opening two T-shaped grooves 5 on the outer wall of the rotating round seat 4, and sliding T-shaped sliders 6 on the inner wall of the T-shaped grooves 5, and welding a cyclone milling cutter body 7 between the two T-shaped sliders 6, the sliding cooperation between the T-shaped grooves 5 and the T-shaped sliders 6 can effectively facilitate the disassembly and replacement of the cyclone milling cutter body 7 used for long-term processing, further improving the subsequent processing accuracy and quality.

[0040] Please see Figure 6The limiting component is set on the fixed round seat 1 and works in conjunction with the disassembly component. Specifically, the limiting component includes two symmetrically arranged T-shaped limiting blocks 8 and threaded columns 10. The two T-shaped limiting blocks 8 are slidably disposed on the inner walls of the two T-shaped sliding grooves 5. The two threaded columns 10 are welded to both ends of the outer wall of the rotating round seat 4. The circumferential surface of the threaded column 10 is threaded with a limiting sleeve 11. A limiting round plate 9 is welded between the two T-shaped limiting blocks 8, and the limiting round plate 9 and the two threaded columns 10 slide in conjunction with each other. Through the mutual cooperation of the T-shaped limiting blocks 8 with the T-shaped sliding grooves 5 and the T-shaped sliders 6, the position of the cyclone milling cutter body 7 can be effectively limited and fixed. Furthermore, through the threaded cooperation of the threaded columns 10 and the limiting sleeves 11, the connection stability between the cyclone milling cutter body 7 and the rotating round seat 4 is further improved.

[0041] Please see Figure 4 Two support rods 12 are symmetrically provided, and the two support rods 12 are welded to both sides of the outer wall of the fixed round seat 1;

[0042] Please see Figure 5 The collection mechanism is mounted on the support rod 12 and works in conjunction with the processing mechanism to collect the metal fragments milled by the cyclone milling. Specifically, the collection mechanism includes a support base 13, a guide groove 14 is provided on the top of the support base 13 and the guide groove 14 is fixedly connected to two support rods 12, a collection box 15 is welded to the bottom of the support base 13, and support legs 16 are welded to the four opposite corners of the bottom of the support base 13.

[0043] In this embodiment: by providing a guide groove 14 at the top of the support base 13 and fixing the guide groove 14 to two support rods 12, and welding a collection box 15 to the bottom of the support base 13, and welding support legs 16 at the four opposite corners of the bottom of the support base 13, it is convenient to collect the metal fragments milled off by the cyclone milling disc body 7, further reducing the labor intensity of the workers and improving the overall working efficiency of the device.

[0045] The working principle and usage process of this utility model are as follows: When the blades on the cyclone milling cutter body 7 are severely worn due to long-term use, seriously affecting the machining accuracy and quality of subsequent cyclone milling, the limiting sleeve 11 can be removed through the threaded engagement of the limiting sleeve 11 and the threaded post 10. Then, through the sliding engagement of the T-shaped limiting block 8 and the T-shaped slide groove 5, and the sliding sleeve of the limiting circular plate 9 and the threaded post 10, the limiting circular plate 9 restricting the position of the cyclone milling cutter body 7 can be removed from the rotating circular seat 4. Then, through the sliding engagement of the T-shaped slide groove 5 and the T-shaped slider 6, the cyclone milling cutter body 7 can be removed from the rotating circular seat 4. The rotating base 4 is removed to disassemble and replace the cyclone milling cutter body 7. The metal fragments that fall off the cyclone milling cutter body 7 are guided by the guide groove 14 and fall into the collection box 15, which facilitates the subsequent cleaning of the metal fragments by the staff and effectively reduces the labor intensity of the staff. In addition, through the mutual cooperation between the driven gear 17 fixed on the outer wall of the rotating base 4 and the transmission gear, and the rotation cooperation between the rotating block 3 and the rotating groove 2 on both sides of the outer wall of the rotating base 4, the cyclone milling cutter body 7 connected to the rotating base 4 can be effectively controlled to perform cyclone milling.
