Abstract

The invention discloses an automatic clamping clamp for U-shaped steel and relates to the field of clamping clamps. The automatic clamping clamp comprises a clamping frame, an end plate clamping assembly, a workpiece clamping assembly and a blocking and abutting mechanism, wherein the blocking and abutting mechanism is fixedly connected to the clamping frame, the clamping frame comprises a supporting plate and a supporting connecting rod, the end plate clamping assembly is fixedly connected to the supporting plate, and the workpiece clamping assembly is connected to the supporting connecting rod. The automatic clamping clamp has the advantages of having variable specifications and being simple in structure, low in cost, simple and convenient to operate and capable of performing automatic operation.

Description

technical field [0001] The invention relates to the field of clamping fixtures, in particular to an automatic clamping fixture for U-shaped steel. Background technique [0002] U-shaped steel is a kind of steel with U-shaped cross section, which has the characteristics of high pressure resistance, long support time, easy installation and not easy to deform, etc. It is mainly used for mine roadway, mine roadway secondary support and mountain tunnel support. When using U-shaped steel, the openings at both ends of the U-shaped steel need to be welded and closed by connecting end plates to meet structural requirements and strength requirements. [0003] At present, the known welding method of U-shaped steel and end plate assembly is performed by at least two workers who will first complete the U-shaped steel and end plate assembly and then perform manual spot welding. During the spot welding process, auxiliary workpieces need to be added as hard supports. Ensure that the distan...
