Abstract

The invention relates to a fixture for a numerically controlled milling machine, in particular to a fixture for a numerically controlled milling machine to clamp a shaft-type workpiece. The technical problem of the present invention is to provide a jig used for a CNC milling machine to clamp a shaft-type workpiece, which can prevent axial shaking and improve machining accuracy. A fixture for clamping shaft-type workpieces for CNC milling machines, including a base, a large bolt, a large bracket, a rectangular guide rod, a large fixed plate, an arc guide plate, a sphere, etc.; The bolt slides in the large through hole, and the top of the base is connected with a large bracket. The fixture provided by the invention for clamping a shaft-type workpiece by a numerical control milling machine can double-clamp and fix the shaft-type workpiece in the radial direction and the axial direction, and the clamping effect is good, thereby preventing the shaft-type workpiece from shaking in the axial direction. It is beneficial to improve the machining accuracy, and it can also tilt the shaft-type workpiece, which is convenient for complex processing of the shaft-type workpiece, and is beneficial to the production and development of the enterprise.

Description

technical field [0001] The invention relates to a fixture for a numerically controlled milling machine, in particular to a fixture for a numerically controlled milling machine to clamp a shaft-type workpiece. Background technique [0002] CNC milling machine, also known as CNC, is an automatic processing equipment developed on the basis of general milling machines. The processing technology of the two is basically the same, and the structure is also somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. Among them, the CNC milling machine with a tool magazine is also called a machining center. After the workpiece is fixed by the fixture, the workpiece can be processed by the CNC milling machine. The existing fixtures for the CNC milling machine usually only perform radial machining on the shaft workpiece. Clamping and fixing can easily lead to axial shaking of the shaft-type workpiece, which seriously affects the...
