Abstract

A universal workpiece holding device is disclosed for securing a workpiece during precision machining. The device includes a securement member with a perimeter wall forming an internal floor. A stationary lip is positioned along at least a portion of the interior perimeter, partially overhanging the floor. At least one opening is formed through the perimeter wall, accommodating at least one clamping member. The clamping member is movable between an open position, allowing the workpiece to be inserted onto the floor beneath the stationary lip, and a closed position, where it presses against the workpiece to secure it. This configuration provides enhanced stability, minimizing unwanted movement during machining operations. The device allows for secure retention of various workpieces while maintaining accessibility for adjustments and removals. Its design supports high-precision manufacturing by reducing backlash and improving clamping efficiency, ensuring reliable workpiece e positioning in demanding machining environments.

Background

BACKGROUND

Maintaining precise control over a workpiece during machining operations is critical to ensuring dimensional accuracy and consistency in manufactured components. As tolerances continue to tighten across industries such as aerospace, medical devices, and high-performance automotive engineering, the effectiveness of traditional workpiece holding methods becomes increasingly scrutinized. Conventional bolting, clamping, and straight jaw vises rely on static friction and mechanical force to restrain the workpiece. Under high cutting forces, rapid tool movement, or thermal expansion, these methods may introduce unwanted micro-movements. Even minor shifts during machining can lead to dimensional deviations that render the final product unusable, necessitating expensive material waste and rework.

Several factors contribute to the instability of traditional workpiece holding mechanisms. First, variations in material properties, such as surface roughness and hardness, affect the effectiveness of clamping forces. Soft or highly polished materials may experience gradual slippage under sustained machining forces, especially when lubricants or coolants are introduced into the environment. Additionally, machining forces exert dynamic loads on the workpiece, resulting in vibration or transient shifts that exceed permissible tolerances. Straight jaw vises and basic clamping systems may not account for these secondary forces, allowing subtle movement that accumulates i

Claims

1. A universal workpiece holding device for holding a workpiece during a precision machining process, the device comprising: a securement member; a perimeter wall of the securement member forming a floor on the securement member within the perimeter wall; a stationary lip formed around at least a portion of an inside of the perimeter wall, the stationary lip partially overhanging the floor within the perimeter wall; at least one opening formed through the perimeter wall; and at least one clamping member configured to slide into at least one opening formed through the perimeter wall between an open position and a closed position; wherein the workpiece is inserted onto the floor of the securement member under the stationary lip formed around at least a portion of an inside of the perimeter wall when the at least one clamping member is in the open position, and the at least one clamping member is moved into the closed position against the workpiece to secure the workpiece to the securement member at least partially under the stationary lip. || 16. A universal workpiece holding device for holding a workpiece during a precision machining process, the device comprising: a first securement member and a second securement member, each securement member having: a perimeter wall of the securement member forming a floor on the securement member within the perimeter wall; a stationary lip formed around at least a portion of an inside of the perimeter wall, the stationary lip partially overhanging the floor within the perimeter wall; at least one opening formed through the perimeter wall; and at least one clamping member configured to slide into at least one opening formed through the perimeter wall between an open position and a closed position; wherein the first securement member is inserted onto the floor of the second securement member under the stationary lip formed around at least a portion of an inside of the perimeter wall of the second securement member when the at least one clamping member of the second securement member is in the open position, and the at least one clamping member of the second securement member is moved into the closed position against the first securement member to secure the first securement member to the second securement member at least partially under the stationary lip of the second securement member; and wherein the workpiece is inserted onto the floor of the first securement member under the stationary lip formed around at least a portion of an inside of the perimeter wall of the first securement member when the at least one clamping member of the first securement member is in the open position, and the at least one clamping member of the first securement member is moved into the closed position against the workpiece to secure the workpiece to the first securement member at least partially under the stationary lip of the first securement member.
