Tension studs and methods with external and internal coolant

Abstract

The present invention relates to a tension stud and method with external and internal coolant. Specifically, the systems and methods include the use of lag studs for connecting a toolholder to a collet in a spindle. The tension stud includes a main body, a seal ring, a spring and a ball, the main body is configured to receive a tool holder, the main body has a longitudinal passage fluidly connected to a cavity, the cavity is fluidly connected to a plurality of longitudinal passages; the sealing A ring is arranged around the end of the longitudinal channel, the sealing ring is in contact with the cavity; the spring is arranged in the cavity; and the ball is in contact with the spring. The ball is arranged to open the end of the longitudinal passage by causing the ball to lose contact with the sealing ring when a first force applied to the ball from the spring is less than a second force applied by fluid flowing through the longitudinal passage. The first force and the second force are substantially opposite in direction of application.

Description

technical field [0001] Embodiments of the subject matter disclosed herein relate generally to machining equipment, and more specifically, to pull stud bolts for use in machining equipment. Background technique [0002] Machining generally refers to a group of processes used to remove material from a workpiece to obtain a desired shape or geometry. Machining is often performed on metal workpieces to produce workpieces for specific applications. Examples of machining processes include milling, turning, and drilling. In the milling process, the tool rotates the cutting surface against the workpiece in order to remove metal. In the turning process, the workpiece rotates against the tool. For drilling, the hole is created by rotating the tool. [0003] Historically, these machining processes began in a largely manual form. With technological advances in power generation and machining, these machining processes have become more automated through the use of cams, for example, ...

AI Technical Summary

Problems solved by technology

Since different machining tasks may require different coolant requirements, having the necessary components for transitioning from internal coolant operation to external coolant operation and then performing this transition can increase downtime between tasks and increase costs , which reduces the overall operating efficiency of the machinery

Also, if the pull stud 302 for internal coolant operation is used with the tool holder 2 for external coolant operation, damage caused by the coolant can occur as the coolant can enter the spindle and damage the electrical components
