Problems solved by technology

The machine tools for processing eccentric crankshafts in the prior art are generally general-purpose machine tools with low rigidity and poor precision. Because there is no fixed eccentric fixture, the installation of the workpiece can only be done manually, and its machining accuracy and efficiency are low, making it difficult to adapt to new industrial structure needs

Abstract

The invention relates to a machining positioning device, in particular to a machine head structure with an eccentric clamp. The machine head structure comprises a machine head box, a main shaft and the eccentric clamp. The main shaft is arranged in the machine head box, one end of the main shaft stretches out of the machine head box and is connected with the eccentric clamp, and the eccentric clamp is provided with a clamping oil cylinder, a crank and a V-shaped table. When a mechanism works, a workpiece is placed on the V-shaped table, the crank is driven by the clamping oil cylinder to swing, and the crank is provided with a pressing head used for fixing the workpiece. The machine head structure is high in rigidity, precision and efficiency, and multiple eccentric crankshafts can be machined by adjusting local components.

Description

technical field [0001] The invention relates to a processing positioning device, in particular to a bed head structure equipped with an eccentric clamp. Background technique [0002] With the rapid expansion of production capacity in related industries, the requirements for the corresponding machine tools are also increasing. In order to meet the needs of the new industrial structure, it is necessary to improve the machine tools. The machine tools for processing eccentric crankshafts in the prior art are generally general-purpose machine tools with low rigidity and poor precision. Because there is no fixed eccentric fixture, the installation of the workpiece can only be done manually, and its machining accuracy and efficiency are low, making it difficult to adapt to new industrial structure needs. Contents of the invention [0003] The purpose of the present invention is to provide a bed head structure equipped with eccentric fixtures, which has strong rigidity, high prec...
