Description

A Lathe Fixture with Adjustable Balance

technical field

The utility model relates to a machine tool clamp, in particular to a lathe clamp with adjustable balance.

Background technique

The three-jaw chuck is a commonly used fixture on the lathe. The three-jaw chuck is provided with a sliding seat, and the claws are fixed on the sliding seat. The flat threads of the three-jaw chuck are meshed with each other. When the wrench is turned through the square hole, the disc bevel gear rotates, and the plane thread on the back of the disc bevel gear simultaneously drives the three claws to move along the radial direction of the three-jaw chuck, realizing automatic centering and Clamping, suitable for clamping round, regular triangle or regular hexagonal workpieces.

Turning is continuous cutting, milling is intermittent cutting, the speed of turning material removal is higher than that of milling, and the surface roughness and machining accuracy of turning workpieces are higher than milling; in actual production, some irregular end cap parts are originally used Milling processing, but considering the processing efficiency and processing accuracy, it is also hoped to be completed on a lathe, but the center of mass of these parts is not on the centerline of the lathe chuck. The high-speed rotation of the machine tool will generate centrifugal inertial force, which acts on the bearing through the bearing. On the machine tool, it causes vibration, produces noise, accelerates bearing wear, shortens the life of the machine tool, and can cause destructive accidents in serious cases; for this reason, the workpiece must be balanced so that it reaches the allowable balance accuracy level, or the generated machinery The vibration amplitude is reduced to the allowable range.
