Detailed Implementation
[0026] like Figures 1 to 5 As shown, a manual threading machine includes:
[0027] A base 1, on which a bearing housing 2 is installed, the base 1 is integrally formed, serving as a bottom support and also as a counterweight;
[0028] A bearing cover plate 3 is disposed at one end of the bearing housing 2, and a limiting ring 4 is installed at one end of the bearing cover plate 3.
[0029] The first connecting flange 5 is rotatably mounted on the limiting ring 4;
[0030] The feed nut 6 has a mounting flange fixed at one end, and the mounting flange is located on one side of the first connecting flange 5.
[0031] The adjusting screw 7 is rotatably disposed within the limiting ring 4, and the adjusting screw 7 is threadedly disposed within the feed nut 6;
[0032] The tool arm seat 8 is located on the top of the bearing housing 2, and has a threaded hole thereon;
[0033] The cutter arm rod 9 is slidably disposed within the cutter arm seat 8, and a groove 901 is provided on the cutter arm rod 9;
[0034] A tool holder 10 is mounted on the tool arm 9, and a threading tool 11 is mounted on the tool holder 10;
[0035] The locking screw 12 has a thread in the threaded hole and is movably disposed in the groove 901. The locking screw 12 is used to lock the tool arm 9.
[0036] Specifically, when the locking screw 12 moves upward, it locks the tool arm 9. At this time, the tool arm 9 can be axially adjusted. During the adjustment process, the locking screw 12 and the groove 901 limit the movement of the tool arm 9, so that the tool arm 9 can only be axially adjusted on the tool arm seat 8 and cannot be rotated within the tool arm seat 8. This limits the direction of the thread cutting tool 11, so that the direction of the thread cutting tool 11 remains unchanged, ensuring the accuracy of thread processing.
[0037] When it is necessary to process threads of different pitches on the workpiece, simply replace the feed nut 6 and the adjusting screw 7.
[0038] Also includes:
[0039] Extension rod 13 is detachably mounted on one end of adjusting screw 7;
[0040] The second connecting flange 14 is installed at one end of the extension rod 13, and the intermediate plate 15 is bolted to the second connecting flange 14;
[0041] The flange welding head 16 is bolted to the intermediate plate 15 and is used to fix the workpiece.
[0042] Furthermore, a bearing 17 is sleeved on the extension rod 13. The bearing 17 is installed inside the bearing housing 2. The bearing 17 is used to provide support for the extension rod 13 and to distribute stress. The extension rod 13 can also slide relative to the bearing 17.
[0043] The bearing 17 is disposed between the extension rod 13 and the bearing housing 2. While supporting the extension rod 13, it reduces the friction between the extension rod 13 and the bearing housing 2 (the reduction of friction can result in less energy loss and higher energy transmission efficiency). In addition, the bearing 17 can also withstand radial loads.
[0044] Furthermore, a locating pin 18 is installed on the bearing housing 2;
[0045] The tool arm seat 8 is provided with a positioning hole, which is used to cooperate with the positioning pin 18;
[0046] The cutter arm seat 8 is detachably mounted on the bearing housing 2 by bolts;
[0047] The locating pin 18 on the bearing housing 2 and the locating hole on the tool arm seat 8 serve as the installation and positioning function. Specifically, when the tool arm is installed, the locating hole is first fitted onto the locating pin 18 to align the installation positions of the tool arm seat 8 and the bearing 17, and then the two are fixed together with bolts.
[0048] Furthermore, the bearing cover plate 3 is detachably installed at one end of the bearing housing 2 by bolts.
[0049] Furthermore, the mounting flange and the first connecting flange 5 are detachably connected by bolts.
[0050] A manual thread-pressing machine, the working principle of which is as follows:
[0051] When using:
[0052] First, fix the workpiece to be processed on the flange welding head 16, and then adjust the position of the thread cutting tool 11 according to the size of the workpiece;
[0053] Specifically, regarding the adjustment: Loosen the locking screw 12 to release the locking of the tool arm 9. Then, the position of the tool arm 9 can be adjusted under the limit of the locking screw 12 and the groove 901. The tool arm 9 drives the tool holder 10 to adjust its position, which in turn drives the thread cutting tool 11 to adjust its position. After the adjustment, tighten the locking screw 12. The locking screw 12 presses the tool arm 9, thereby fixing the position of the thread cutting tool 11.
[0054] When threading:
[0055] Rotate the feed nut 6, and the adjusting screw 7 moves under the drive of the feed nut 6 (i.e., it moves forward and backward and rotates synchronously). The extension rod 13 moves synchronously with the adjusting screw 7. The extension rod 13 drives the second connecting flange 14 and the intermediate plate 15 installed thereon to move, which in turn drives the flange welding head 16 installed at the other end of the intermediate plate 15 to move, which in turn drives the workpiece to move and cooperate with the thread cutting tool 11 to perform thread processing.
