Boring clamp and operation method thereof

Abstract

The invention discloses a boring clamp and an operation method thereof. The boring clamp includes a clamp body and a pressing ring; the clamp body is provided with a base, and a semi-cylinder structure is fixed and supported on the base; the semi-circular cylinder structure includes an upper end surface, an arc surface and a side end surface; the upper end surface is a workpiece mounting surface;the side end surface is a straightening datum surface; a datum hole is formed in the clamp body; a semi-circular clamp rabbet is machined in the upper end surface; a positioning block on the left sideand a positioning block on the right side are slidably mounted on the upper end surface; the positioning block on the left side and the positioning block on the right side are symmetrical about the center of the clamp rabbet; a plurality of pressing plates are slidably arranged on the upper end surface in the circumferential direction; and the pressing ring is in a semi-circular shape, is mountedon the clamp body through a connecting device and used for clamping the upper end of a workpiece on the clamp body. The boring clamp can realize the quick alignment of the workpiece, and the alignment efficiency is high; and the force of the workpiece is uniform, so that the machining precision is not affected.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, relates to the technical field of engine part manufacturing auxiliary fixtures, and in particular relates to a boring fixture and an operating method thereof. Background technique [0002] During the processing of the compressor casing, since the shape of the workpiece to be processed is semicircular, the alignment process of the workpiece is extremely difficult; in the prior art, the alignment method of the workpiece during the boring process of the longitudinal joint surface is mostly manual alignment. The alignment efficiency is low. In addition, the compressor case has a thin-walled structure, and its material Ti40 is a difficult-to-machine material. The vibration of the workpiece during the processing has a great influence on the accuracy of the hole; the current workpiece clamping is mostly the clamping method of the pressure plate. It will cause the workpiece to vibrate d...

[0002] During the processing of the compressor casing, since the shape of the workpiece to be processed is semicircular, the alignment process of the workpiece is extremely difficult; in the prior art, the alignment method of the workpiece during the boring process of the longitudinal joint surface is mostly manual alignment. Alignment efficiency is low

In addition, the compressor case has a thin-walled structure, and its material Ti40 is a difficult-to-machine material. The vibration of the workpiece during the processing has a great influence on the accuracy of the hole; the current workpiece clamping is mostly the clamping method of the pressure plate. It will cause the workpiece to vibrate due to uneven force, which will affect the machining accuracy
