Description

A device for removing broken bolts

technical field

The utility model belongs to the technical field of mechanical tools, in particular to a device for taking out a broken bolt.

Background technique

Bolts are widely used in production and life. As a necessities of daily life, all kinds of furniture, machinery and equipment, industrial production, construction, etc. will use bolts, and the demand is also relatively large, with different models and sizes, so the use and handling methods of bolts are very important. important. However, it is inevitable that the bolts will break during use, which will affect the normal operation and work efficiency of the work. At this time, it is necessary to use various methods to take out the broken bolts, and at the same time avoid as much as possible to the corresponding surrounding damage to components.

At present, the broken bolts mainly occur in the following three situations: the first is that a small part of the bolt is exposed outside the component. In this case, the bolt is easy to take out. For example, other objects can be welded in the leakage part, and then the broken bolt can be taken out. The second is that the leakage part is basically parallel to the bolt hole of the component. In this case, if the bolt is relatively loose, you can cut it with a hand grinder, cut a slot on the section of the bolt, and twist it out with a flat-blade screwdriver. If the bolts are relatively tight, you can use electric welding to pile up the screw section, and then add the welding nut, and then the screw can be twisted out. The third type is that the bolt section is inside the component. Generally, in this case, a hand electric drill is used to drill a hole in the screw section, and then an extractor is used to twist the screw out. However, when the position of the cross section is relatively deep, the bolts and components are relatively tightly connected, and the hole diameter is relatively small, the application of the ordinary removal device will not be ideal, which delays the normal work progress.
