Rotatable fixture for irregular objects

Abstract

The invention discloses a rotatable clamp for irregular objects. The rotatable clamp comprises a chuck body, wherein an annular bracket is arranged above the chuck body, and T-shaped slots are formedin the annular bracket; racks are arranged on the side surface of the chuck body and are connected to a gear and a stepping motor; an oil disc is fixed on the chuck body, a conical tooth table is arranged above the oil disc, protruded rails are arranged on the conical tooth table, four clamp claws are arranged above the conical tooth table, transverse H-shaped rods penetrate through the clamp claws, T-shaped protruded strips matched with the T-shaped slots are arranged above the clamp claws, and arc-shaped grooves matched with the protruded rails are arranged below the clamp claws; a fixed clamp plate is fixed on the inner side of the oil disc, an oil disc oil inlet cavity is formed in one side of the fixed clamp plat, an oil disc oil outlet cavity is formed in the other side of the fixedclamp plate, and a push plate is arranged outside the conical tooth table; a hole A of the first reversing valve is connected to the oil disc oil inlet cavity, a hole B, a hole T and a hole P of the first reversing valve are respectively connected with the oil disc oil outlet cavity, an oil tank and an oil pump, and the oil pump is connected with the oil tank. The rotatable clamp has the characteristics that the structure is simple, the dismount and mount are convenient, the rotary operation is realized, and the irregular objects can be clamped.

Description

technical field [0001] The invention relates to a four-claw clamp, in particular to a rotatable clamp for irregular objects. Background technique [0002] In today's society, welding fixture design is one of the most critical work contents in the production preparation process in the field of mechanical manufacturing. At the same time, in the process of welding production process design, welding fixture design is also one of the most critical components. For many mechanical manufacturing and processing fields, if there is no technical support and guarantee provided by welding fixtures, there will be no final welding products. However, in the process of practical work at the present stage, the clamping methods adopted for pipe parts are either traditional special fixtures or combined fixtures that are expensive and complex in structure. For traditional special fixtures, not only requires a lot of manpower, It also does not have a fast and accurate operating mechanism, and c...

Problems solved by technology

However, in the process of practical work at the present stage, the clamping methods adopted for pipe parts are either traditional special fixtures or combined fixtures that are expensive and complex in structure. For traditional special fixtures, not only requires a lot of manpower, It does not have a fast and accurate operating mechanism, and cannot automatically rotate itself, causing inconvenience to welding personnel, resulting in low quality clamping and welding work, and uneven quality of welding products

In addition, the traditional special-purpose fixture is cumbersome or impossible to locate irregular objects, and cannot ensure that the irregular objects are positioned at the axis of the fixture, and cannot stably grip heavy irregular-shaped objects, causing work Inefficiency and lower quality of work
