Problems solved by technology

At present, during the grinding process of the electrode cap, the following problems often occur: during the grinding process, the electrode cap jumps, resulting in an ellipse in the cutting shape of the electrode cap; Low efficiency, fast blade wear, large cutting waste, easy to block the tool, and affect the quality of grinding; the tool seat needs to increase the positioning surface to ensure the centering of the electrode cap, and the tool seat has high processing position accuracy requirements. The processing error and assembly error will lead to the inconsistency of the cutting amount of the blade, which cannot be seriously ground, and the grinding of the upper and lower electrode caps is inconsistent, which will affect the service life of the electrode cap.

Abstract

The invention relates to a blade mechanism, and particularly relates to a resistance welding electrode trimming tool with spiral arc edges. The resistance welding electrode trimming tool comprises a tool apron and a blade mechanism; the blade mechanism comprises a blade; the upper end and the lower end of the blade are each provided with one edge; each edge comprises an end face forming face, an electrode cap guide face, an anti-impact chamfer and an edge rear angle face; the blade further comprises a first side face, a second side face and an installation face; and each cutting edge is a spiral arc formed by intersecting the corresponding electrode cap guide face with the first side face. According to the resistance welding electrode trimming tool, the edges are the spiral arcs, and compared with linear edge lines located on the same plane, cutting is stable, and efficiency is high; the cutting torque is small, the length of the edges participating in cutting is increased, the spiral lead angles of the spiral arcs increase the axial tension, reduce the radial force and improve the positioning stability of electrode caps; and the actual working front angle is increased through the spiral lead angles, the cutting edges are sharp, the cutting force is reduced, chip removal is facilitated, and the workpiece surface roughness is more ideal.

Description

technical field [0001] The invention relates to a dressing tool, in particular to a resistance welding electrode dressing tool with a spiral arc edge. Background technique [0002] At present, in the automotive industry, most of the robot welding guns use automatic grinders to grind the electrode caps instead of manual grinding of the electrode caps. The process of grinding the electrode caps is to use the grinding blades in the grinder to cut the electrode caps. Processing, re-dressing the surface appearance and shape of the electrode cap, the amount of electrode cap grinding depends on the grinding time and grinding pressure of the electrode cap. At present, during the grinding process of the electrode cap, the following problems often occur: during the grinding process, the electrode cap jumps, resulting in an ellipse in the cutting shape of the electrode cap; Low efficiency, fast blade wear, large cutting waste, easy to block the tool, and affect the quality of grinding...
