Abstract

The invention relates to a drill bit self-grinding and fixing device for automobile front axle drilling, which is used for solving the problem that an existing self-grinding drill bit is not firmly fixed. The device comprises a fixing column and a drill bit, a fixing groove is formed in the fixing column, a bearing column is arranged in the fixing groove, ejection assemblies are arranged at the upper end and the lower end of the bearing column, a plurality of threaded rods are movably inserted into the bearing column, nuts are arranged on the threaded rods in a threaded mode, and the nuts abutagainst the bearing column; in the present invention, a combined structure of a first threaded hole, a second threaded hole and a fixing screw is added for first-step fixing of a fixing column and adrill bit, a clamping and fixing component is set for the second -step fixing of the fixing column and the drill bit, so that the effect of stably fixing the drill bit can be achieved through multi-step fixing, and the problem that in the prior art, when a single fixing screw is adopted for fixing, fixing is not stable is solved; and therefore in practical application, the effect of stable fixingcan be achieved, and therefore the drill bit fixing device has high practical value.

Description

technical field [0001] The invention relates to the technical field of production equipment for automobile forgings, in particular to a drill self-grinding fixing device for drilling the front axle of automobiles. Background technique [0002] Forging is a machining process. A forging is an object in which a metal is pressured to form a required shape or a suitable compression force through plastic deformation. This force is typically achieved through the use of a hammer or pressure. The forging process creates a refined grain structure and improves the physical properties of the metal. In the actual use of components, a correct design can make the particle flow in the direction of the main pressure. Forgings need to be consistent from piece to piece, free of any porosity, inclusions, or other blemishes. Components produced by this method have a high ratio of strength to weight. The advantages of forgings are stretchable length; shrinkable length, stretchable cross sect...
