Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] In order to understand this solution more clearly, this embodiment takes the processing of the inner arc surface of the oil pipe support bar as an example. The processing tooling of this application can be used to process the inner arc surface of various long parts, not limited to the oil pipe support bar. Inner arc surface processing.

[0033] Here is a brief description of the tubing support strips. figure 1 It is a front view of an oil pipe support bar provided by an embodiment of the present invention. Such as figure 1 As shown, the end surface of the tubing support bar 1 is rectangular, wherein one side of the rectangle is an inner arc. Therefore, the tubing support bar 1 includes three planes and an inner arc surface 11...

Abstract

The invention discloses a tool for processing inner arc faces of elongated parts and belongs to the technical field of machining. The tool comprises a tube body, a plurality of first side plates, a plurality of second side plates and a plurality of fixing devices; the tube body is peripherally provided with a plurality of openings at intervals which are capable of receiving elongated parts; each opening is provided with one first side plate and one second side plate; the first side plates and the second side plates are arranged in parallel; the middle faces for the first and second side platescross the diameter of the tube body and are parallel to the first side plates and the second side plates; the first side plates and the second side plates are equally spaced; each fixing device includes first and second fixing devices arranged in pairs; the first and second fixing devices are used for fixing and clamping corresponding elongated parts. The tool herein allows multiple elongated parts to be fixed, so that inner arc surfaces of the multiple elongated parts can be machined at a time by turning, and machining efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing tool and method for the inner arc surface of a long part. Background technique [0002] The controllable pitch propeller is a ship power propulsion device, which generally includes a hub blade assembly, a controllable pitch propeller oil pipe assembly and an oil distributor assembly. The controllable pitch propeller oil pipe assembly connects the oil distributor assembly and the hub blade assembly, and is used to transfer the high-pressure oil from the oil distributor assembly to the hub blade assembly, thereby changing the magnitude and direction of thrust. The controllable pitch propeller oil pipe assembly generally includes a shaft system and an oil pipe sleeved in the shaft system. In order to ensure that the oil pipe is stably fixed in the shaft system, a shaft sleeve is usually installed in the shaft system, and the oil pipe support bar is install...
