Lathe fixture

Lathe fixtures are generally used to process rotating parts. The fixtures are mounted on the machine tool spindle. During turning, the fixtures drive the workpieces to rotate. Since the spindle speed is generally very high, when designing lathe fixtures, attention should be paid to solving the mass balance caused by the rotation of the fixtures. problems and operational safety issues. The connection method between the lathe fixture and the machine tool depends on the structure of the front end of the spindle, and the rotation accuracy of the fixture depends on the accuracy of the connection with the machine tool.

  1. The connection between the lathe clamp and the machine tool spindle, faceplate or transition flange must be safe and reliable.
  2. The structure of the lathe fixture should be simple and compact, and the weight should be as light as possible.
  3. The fixture should be balanced when working. The center of gravity of the lathe fixture should be as close to the rotation axis as possible. The position of the balance weight should be far away from the rotation axis and can be adjusted in the circumferential direction.
  4. In order to facilitate the alignment center during installation, the maximum outer circle of the lathe fixture should be designed as the benchmark for calibrating the rotation center or alignment circle.
  5. The maximum rotation diameter of the lathe fixture is not allowed to interfere with the machine tool.
  6. Lathe fixtures should not have protruding parts on the circumference. Lathe fixtures should generally be equipped with protective covers to prevent personal accidents.
