Description

Technical Field

[0001] The utility model relates to the technical field of metal processing fixtures, in particular to a horizontal fixture tooling for metal parts processing. Background Art

[0002] At present, the existing technology often uses CNC machine tools to process metal parts. Metal processing requires clamps, but the current clamps are usually used for vertical installation, and then the CNC machine tool processes one surface of the part. If the clamp is installed horizontally, the exposed position of the part fixed on the clamp is very close to the clamp body, which will block the processing tool. Most of the existing clamps are fixed on all sides of the part. This is because under the action of gravity, the part will be pressed downward to the lower side of the clamp due to gravity. Therefore, it is necessary to ensure the stability of the part and a structure for fixing the part must be set on the lower side. However, such a setting will make it impossible to process the part from the edge of the clamp to the center. Utility Model Content
