Abstract

The invention provides a clamp special for a flat turbine head end face. By using the clamp, the clamping positioning of a three-jaw chuck meets a clamping requirement, the machining efficiency is high, a machined surface is smooth, a fracture phenomenon is not easy to cause, and the centre beat of a machined component is low. The clamp special for the flat turbine head end face comprises the three-jaw chuck, a base and a flat turbine, and is characterized in that: the upper part of the base is provided with an open cavity body; the flat turbine is arranged in the cavity body; an end cover is covered on the outer end surface of the cavity body; a centre hole is formed in the end cover; the head end surface of the flat turbine is exposed from the centre hole of the end cover; the outer circumference of a worm wheel of the flat turbine is adhered to the inner end surface of the cavity; and the three-jaw chuck clamps the outer edge surface of the base.

Description

technical field [0001] The invention relates to the technical field of turbine manufacturing, in particular to a special clamp for the end face of a flat turbine head. Background technique [0002] The working condition of the turbine is harsh, so the special material K18 is used to make it resistant to high temperature, not easy to deform, and high in strength. [0003] When processing the end face of the flat turbine head, the existing technology uses a three-jaw chuck to clamp the edge of the turbine head to fix it. [0004] However, in production, it was found that due to the special material and strong cutting force, the clamping position of the three-jaw chuck could not meet the clamping requirements, resulting in reduced processing efficiency, rough processed surface, easy chipping, and large center runout of the processed parts. Contents of the invention [0005] In view of the above problems, the present invention provides a special fixture for the flat turbi...
