Machining fixture for numerical-control milling machine

Abstract

The invention discloses a machining fixture for a numerical-control milling machine. The machining fixture for the numerical-control milling machine comprises a spring clamping sleeve body and a screw. A cavity is formed in the top of the spring clamping sleeve body. The screw is mounted in the cavity. A through hole communicating with the cavity is further formed in the spring clamping sleeve body and is of a conical structure. The screw is sleeved with a washer. A plurality of through grooves are evenly formed in the spring clamping sleeve body in the circumferential direction, and an annular groove is further formed in the upper portion of the spring clamping sleeve body. According to the machining fixture for the numerical-control milling machine, the through hole in the spring clamping sleeve body is of the conical structure so that the clamping requirement for machining of a tool with a tapered tool handle can be met, the purpose of mounting the tool with the tapered tool handle on the numerical-control milling machine is well achieved, and the defects of an existing straight-hole spring clamping sleeve in the using process are overcome. The machining fixture for the numerical-control milling machine is simple in structure and convenient to use, has good economic benefits and can be widely used and popularized in the technical field of machining.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing fixture for a numerically controlled milling machine. Background technique [0002] At present, there is often a kind of workpiece used in ordinary CNC lathe processing workpieces. The rod part is small and the head diameter is large and flat. Usually, a section of lathe chuck jaws is turned, so that the chuck jaws cannot be used when turning general workpieces. , it needs to be replaced with a set of normal chuck jaws, which increases the cost, or because the diameter is too small, the normal chuck jaws can only clamp workpieces with a diameter greater than 10mm, while workpieces with a diameter of less than 10mm cannot be clamped. It is necessary to replace the special chuck jaws; most of the instrument lathes and hand lathes use spring chucks for quick clamping, which is suitable for the processing of large batches of small parts, and for...

Problems solved by technology

However, since the through hole of the clamping part of the spring collet is a straight hole, only the tool with a straight shank can be installed, and the tool with a tapered shank cannot be clamped.
