Tapping chuck

Tapping chuck is a tool holder for internal thread processing, a versatile tool series for holding taps, with a wide variety. It is one of the most common fixtures in machining.
Chinese name
Tapping chuck
Nature
Multi-purpose tool series for holding taps,
Features
Rigid, floating (torque protection)
Scope of application
One of the most common fixtures in machining
According to the tail handle, it can be divided into:
According to the tapping process, it can be divided into: rigid, floating (torque protection)
Straight shank tapping chuck:
Generally speaking, this kind of tail shank is less used. Because about 90% of the machine tools, the fixtures are connected with tapered shanks, and only some special machine tools are used. Because of the straight shank connection, there are several disease problems:
A.
The problem of concentricity, the cylindrical axis surface and the hole surface, if you want to dismantle, you need a clearance fit.
And this convenience goes hand in hand with concentricity
Conversely, the higher the concentricity, the smaller the gap, and the gap
The smaller the size, the less convenient it is to load and unload.
B:
The connection of the shaft asks if you keep the axial rotation torque problem, simply keep it from turning.
There are too many problems, only two aspects are mentioned here, so that the torque quick-change chuck will be explained below.

Tapping chuck components:
1. Taper shank 2. Morse sleeve 3. Connecting rod 4.7 kinds of tap sleeves
Use and maintenance:
1. When cleaning, first clean the chuck cone and the machine tool spindle, then install the main body cone on the main shaft, and tap the end surface of the main body with a rubber hammer or wooden hammer to ensure tightness, firmness or tension with a post.
2. Select the corresponding sleeve to clean according to the processing needs, put it into the inner hole of the main body, and gently push the main body sliding cap, so that the square of the sleeve is inserted into the square hole in the main body, and then the corresponding tool is clamped on the sleeve. Can be processed.
3. If using the tapping function, remember to loosen the nut first. When processing, according to the needs of the tap torque, tighten the nut (the nut is not easy to overtighten) to prevent the tap from sliding.
4. When the tap is placed in the tap sleeve, care should be taken to place the square handle into the square hole in the collet to increase the torque.
5. Gently push the sliding cap, you can first remove the sleeve (or replace), after use, clean the rust, body, collet
