Workpiece clamping clamp and wire spool welder using same

Abstract

The invention provides a workpiece clamping clamp and a wire spool welder using same. The welder comprises a clamping clamp, wherein a circumferential datum plane is arranged on a positioning base of the clamping clamp; a plurality of clamping assemblies are arranged on the clamping clamp; each clamping assembly can reciprocate in a guiding mode along the circumference; a clamping block of each clamping assembly is driven by a clamping drive mechanism to close to clamp the constitutional units when each clamping assembly moves towards the corresponding circumferential datum plane, and to open when each clamping assembly moves away from the corresponding circumferential datum plane; and each clamping assembly is provided with a fixed station on reciprocating motion stroke, so that an arc-shaped part of each constitutional unit is resisted against the corresponding circumferential datum plane when each clamping assembly moves to the fixed station. When the constitutional units are clamped and fixed by the clamping assemblies, the arc-shaped parts of the constitutional units are further directly resisted against and fixed on the circumferential datum plane by the clamping assembly which moves towards the circumferential datum plane, so that automatic and accurate positioning of each constitutional unit is finally guaranteed.

Description

technical field [0001] The invention relates to a workpiece clamping fixture and a wire coil welding machine using the clamping fixture. Background technique [0002] Welding is a commonly used fixed connection method in the mechanical field. Most welding processes require the use of welding wire. During welding, the welding wire and the workpiece need to be melted at high temperature, and a fixed connection is formed after cooling. In the process of welding wire production, welding wire packaging and welding wire use, the winding reel is required. When in use, the welding wire is wound in layers in the groove in the middle of the winding reel. Commonly used winding reels are mostly made by injection molding, which has many consumables, high cost, and is prone to breakage, which affects the normal support of the welding wire. [0003] In the Chinese utility model patent specification whose authorized announcement number is CN201128645Y, a kind of such as figure 1 The show...
