WHAT IS A FLANGE FLANGE THIMBLE?

Flange flange thimble is a common machine tool part in mechanical processing, there are fixed flange thimble and movable flange thimble. What is their role? How should we maintain and extend the service life of flange flange thimble?

 

Introduction of flange flange thimble

The function of the flange flange thimble is that the lathe is used to center and bear the gravity and cutting force of the workpiece. The front flange thimble of the lathe can be directly installed in the taper hole of the spindle of the lathe. The front flange thimble and the workpiece rotate together without relative movement, so there is no need to quench. The flange thimble can also be used for drilling, threading and reaming of workpieces.

A flange thimble for machine tool attachments commonly used in machine tools, which is connected to the housing by a three-jaw self-centering chuck or a four-jaw chuck with fasteners, and a bearing is provided between the housing and the mandrel, which is embedded and fitted with a fixing pin. The utility model is characterized in that one end of the flange thimble is convex pointed cone and oblique spline, and the other end is concave hemispherical and tapered blind hole.

 

The composition of flange fixed flange thimble

The flange flange thimble is mainly composed of a flange thimble, clamping device, casing, fixing pin, bearing and mandrel. One end of the flange thimble can push the center hole or the inner hole of the pipe material, and the other end can have a spherical or conical part at the top end. The flange thimble is fixed by the clamping device. When the parts are not allowed or unable to punch the center hole, the turning device can be directly clamped by the clamping device. The housing and the mandrel are drilled with pin holes, and the pin is inserted or removed to achieve the function of the flange thimble.

 

Routine maintenance of rotary flange thimble

The first is to find the bearing and cap on the rotary flange thimble. Some people may not know where the bearing and cap are. The part with two small holes on the head is the flange thimble and cap. Then, insert the tool into the small hole and rotate it gently. The bearing and the cap can be taken out, and then the screw at the rear of the tapered sleeve end is removed, and then the tool is used to push the bearing out of the flange thimble housing from the rear, and the replacement of the deep groove bearing and thrust bearing is completed.

 

There are many types of rotary flange thimble. When using it, choose different rotary flange thimble according to the specific conditions of use. The rotary flange thimble has high wear resistance. There will be no damage when using the rotary flange thimble. The rotary flange thimble is often used in some In large equipment, pay attention to daily maintenance when using the rotary flange thimble, so as to ensure the normal operation of the machine.
