Rotatable clamp for circumferential hole drilling of ring-like parts with end face holes

Abstract

The invention provides a rotatable clamp for circumferential hole drilling of ring-like parts with end face holes and relates to the technical field of machining. The problems that in existing ring-like part radial hole machining, a drill bit directly drills in a circular arc, and a machining plane does not exist, so that the positioning difficulty of the drill bit is large, vibration is large, the size and position accuracy of a machined radial hole are poor, the technological requirement is not met, the part machining quality is affected, and the drill bit is extremely prone to being brokento cause the low production efficiency are solved. A rotatable clamp body and a fixed clamp body are sequentially positioned and mounted on a support through hexagonal head screws and nuts, a workpiece is placed in an ring-shaped area of the rotatable clamp body, three pressing plates are pressed on the workpiece and three arc-shaped fixing plates, the three pressing plates are fixed to the rotatable clamp body through three first fixing screws, and the workpiece is positioned on the rotatable clamp body through a second fixing screw. The rotatable clamp is used for drilling machining of circumferential holes of the ring-like parts.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a rotatable fixture for drilling peripheral holes on ring parts with end face holes. Background technique [0002] Such as Figure 9 and Figure 10 The workpiece 12 shown is an annular structural part. Both sides of the workpiece 12 are planes and a round hole Φ is opened on the end surface. Three radial holes are required to be evenly distributed in the circumferential direction of the workpiece 12 . The ring structure of the part is machined and formed, and the end face hole is easy to be clamped and processed, and the three radial holes of the workpiece 12 are all perpendicular to the arc surface. When machining radial holes in the existing ring parts, because the drill directly drills on the arc and has no processing plane, the positioning of the drill is difficult and the vibration is large, resulting in poor size and position accuracy of the processed radial ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that when the existing ring parts process radial holes, because the drill directly drills on the arc, there is no machining plane, the positioning of the drill is difficult, and the vibration is large, resulting in the processed radial holes. The size and position accuracy of the hole is poor, which cannot meet the process requirements, which affects the processing quality of the parts, and the drill bit is easily broken, resulting in low production efficiency.
