Tungsten needle automatic sharpening equipment

Abstract

The invention belongs to the technical field of welding consumable repair and maintenance equipment, and relates to tungsten needle repair and maintenance equipment, in particular to automatic tungsten needle sharpening equipment. According to the equipment, the inner conical surface and an inner cylinder with one end chopped into four parts are used for holding a tungsten needle tightly, a motorand a gear drive the tungsten needle to rotate, a rotating connector is used for guiding pressure air into a rotating air cylinder, and two grinding wheels which form a 50-degree angle and rotate at ahigh speed are used for getting close to the tungsten needle slowly. Compared with the manual manner, the ground conical angle is accurate in size and is of a standard conical shape with the conicalangle being 50 degrees, the tungsten needle is only affected by the couple effect, no bending force is generated, bending or brittleness can be avoided effectively, the efficiency is high, workers stand outside the safety distance to operate the equipment, risk to the human body is small, the grinding wheels are worn uniformly, and the service life of the grinding wheels is longer.

Description

technical field [0001] The invention belongs to the technical field of maintenance equipment for welding consumables, and relates to maintenance equipment for tungsten needles, in particular to automatic sharpening equipment for tungsten needles. Background technique [0002] The tungsten needle used in argon arc welding needs to be sharpened at one end before use. The ground tungsten needle includes two parts: a conical part and a straight rod part. The cone angle of the conical part is 50 degrees. [0003] At present, it is generally used to manually hold a tungsten needle close to the high-speed rotating grinding wheel for grinding, grasp the angle and grinding amount based on experience, and rotate while grinding. It is difficult to ensure the consistency of the shape of the conical part of the ground tungsten needle, especially the angle. If the grinding wheel is too tight for single-sided grinding, the tungsten needle may become bent or brittle, and if the grinding wh...
