Problems solved by technology
Most of the bolted connection is made of black iron material, which is easy to rust; many of the bolted connections use serious environmental pollution, and there are many thread deposits; When threaded connections are used, the thread profile is deformed due to intentional or external damage, etc.
Such reasons cause the thread size and structure of the bolt to change, and the nut cannot be disassembled smoothly or even the nut cannot be disassembled.

Embodiment Construction
[0021] Referring to Fig. 1, an internally threaded sleeve 1 is provided, and on the inner side wall of the internally threaded sleeve 1, a chip removal groove 2 is provided along the axial direction of the internally threaded sleeve 1, and the notch of the chip removal groove 2 forms a teeth cleaning edge According to the requirements of metal cutting, select materials and conduct heat treatment to ensure the service life.
[0022] In a specific implementation, the chip removal groove 2 is formed through the inner threaded sleeve 1 in the axial direction, so as to facilitate the discharge of chips.
[0023] There are no less than two chip removal grooves 2, three shown in the figure, and each chip removal groove 2 is evenly distributed on the circumference of the internally threaded sleeve 1 .
[0024] In order to implement the teeth cleaning operation, it is necessary to set the associated handle 3 on the internally threaded sleeve 1 .
[0025] As shown in Figure 1, in this ...

A tooth-cleaning sleeve nut is characterized in that the tooth-cleaning sleeve nut is provided with an internal thread sleeve, a chip removing slot is arranged on the inner side wall of the internal thread sleeve along the axial direction of the internal thread sleeve, thus leading the slot opening of the chip removing slot to form a tooth-cleaning blade. On the one hand, the tooth-cleaning blade formed on the slot opening of the chip removing slot can better realize the tooth-cleaning; on the other hand, the arrangement of the slot removing slot can cause the removed chips to fall into the chip removing slot directly, thus avoiding the chips blocking the rotation of the sleeve during the slot washing process and leading the tooth-cleaning operation to be more simple and reliable and have good tooth-cleaning effect. The invention can implement the repair and the tooth-cleaning of the larger modular thread on the smaller radial size, which can reflect more benefits in the narrow operation sites in addition to meeting the operation on the normal occasions.
Description
technical field [0001] The invention relates to a tool, more specifically a tool for repairing the thread on the surface of a bolt column so as to smoothly disassemble the nut. Background technique [0002] Bolt connection is a detachable connection widely used in metal equipment and steel structures in machinery, electric power, petrochemical and other industries. Most of the bolted connection is made of black iron material, which is easy to rust; many of the bolted connections use serious environmental pollution, and there are many thread deposits; When threaded connections are used, the thread profile is deformed due to intentional or external damage, etc. Such reasons cause the bolt thread size and structure to change, and the nut cannot be disassembled smoothly or even the nut cannot be disassembled. Contents of the invention [0003] In order to avoid the disadvantages of the above-mentioned prior art, the present invention provides a sleeve nut for cleaning teeth,...
