Workpiece clamping fixture and winding reel welding machine using the clamping fixture

Abstract

The invention provides a workpiece clamping fixture and a winding reel welding machine using the clamping fixture. The welding machine includes a clamping fixture. The positioning seat of the clamping fixture is provided with a circular reference plane. Each clamping component can move back and forth along the radial direction of the circumference, and the clamping block of each clamping component is driven by the clamping drive mechanism to close when each clamping component moves close to the corresponding circumferential reference plane to clamp the component The unit is opened when each clamping component moves away from the corresponding circumferential reference plane. Each clamping component has a fixed station on the reciprocating movement stroke. When each clamping component moves to the fixed station, the arc shape of each component unit The top is pressed against the circumferential datum plane. While the clamping component clamps and fixes the constituent units, the clamping component that moves close to the circumferential reference plane also directly presses and fixes the arc-shaped part of the constituent units on the circumferential reference plane, finally ensuring the automatic and accurate positioning of each constituent unit .

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.
