Problems solved by technology
Repeatedly dragging the tailstock of the lathe, resulting in high labor intensity for workers; repeated tool replacement makes the processing efficiency low
Especially when processing large-size threads, the cutting radial force is large, the lathe is worn, and the tool rotates, resulting in reduced processing accuracy, and even the thread cannot be processed normally.

Embodiment Construction
[0016] The present invention will be further described below according to the accompanying drawings and embodiments.
[0017] Such as figure 2 and image 3 As shown, a tapping tool for internal thread processing includes a tap 3-1, a tap sleeve 3-2 and a tapping frame body 3-3, and the tap 3-1 is fixed on the tap sleeve 3-2 In the installation hole and fastened by bolts, the tap sleeve 3-2 is set in the sleeve 3-31 of the tapping frame body 3-3; the sleeve 3-31 is symmetrically provided with a through T-shaped The waist-shaped hole 3-21 of the sleeve 3-31 is the smaller hole of the waist-shaped hole 3-21, and the pin shaft 3-4 passes through the waist-shaped hole 3-21 of the sleeve 3-31 to tap Cover 3-2 is fixed in the sleeve 3-31 of tapping frame body 3-3, and the two ends of bearing pin 3-4 are provided with rolling element 3-6, and rolling element 3-6 is positioned at the waist hole 3-21. In the larger hole; when the tapping tool is in the tapping operation, when the to...

The invention belongs to the technical field of thread machining, and particularly relates to a tapping tool for internal thread machining and a method for machining internal threads by a lathe. The tapping tool for internal thread machining comprises a screw tap, a tapping sleeve and a tapping frame body, wherein the screw tap is fixed in a mounting hole of the tapping sleeve, a sleeve of the tapping frame body sleeves the tapping sleeve, and a mounting base is connected to the outer side of the sleeve. A drill bit is installed on a lathe tailstock. A mounting base of the tapping tool is movably connected to the lathe tailstock. A workpiece is clamped on a chuck of the lathe. The lathe tailstock is pushed to drill the workpiece; and after tool retracting, a lathe tool rest is adjusted, sothat the tapping tool can be used for flexible tapping. By means of the tapping tool and the method, the thread machining efficiency is improved, the time for replacing a cutter is only 1 / 3 that of original occasions, the screw tap is used for flexible feeding instead, and the operation is simple and convenient to perform. The labor intensity of workers is greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of thread processing, and in particular relates to a tapping tool for processing internal threads and a method for processing internal threads with a lathe. Background technique [0002] Generally, the thread processing of the workpiece requires the operator to repeatedly drag the tailstock of the lathe, and use the tool installed on the tailstock to punch holes first and then tap. Repeatedly dragging the tailstock of the lathe leads to high labor intensity for workers; repeated tool replacement makes the processing efficiency low. Especially when processing large-size threads, the cutting radial force is large, the lathe is worn, and the tool rotates, resulting in reduced processing accuracy, and even the thread cannot be processed normally. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned prior art, the present invention provides a tapping tool for machini...
