Clamp for milling spiral groove on surface of shaft type work piece

Abstract

The invention discloses a clamp for milling a spiral groove on the surface of a shaft type work piece. The clamp comprises a milling machine table, wherein one end of the milling machine table is provided with a universal indexing head, and the other end of the milling machine table is provided with a locating tailstock; the universal indexing head and the locating tailstock are located at the same horizontal straight line; the milling machine table is provided with self-regulating dampers; the self-regulating dampers are located between the locating tailstock and the universal indexing head; the locating tailstock comprises a centre, a crank and a base; the base is arranged on the milling machine table; the base is provided with the centre; the centre is connected with the crank; and the number of the self-regulating dampers is two. The clamp for milling the spiral groove on the surface of the shaft type work piece disclosed by the invention is simple to operate, and can reduce milling difficulty so as to reduce milling time and milling cost; the clamp is suitable for batch machining; and the self-regulating damper can effectively reduce the vibration caused by the contact of the shaft type work piece and a tool, thus improving milling precision.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for milling a spiral groove on the surface of a shaft workpiece. Background technique [0002] At present, in principle, the machining of the spiral groove on the surface of the shaft workpiece can be done by rotating the workpiece and feeding the tool in the axial direction, or by rotating the workpiece and feeding in the axial direction while the tool works. Compared with lathes, using a milling machine to mill spiral grooves is more efficient and has a wider range of use. The milling cutter can reach a larger cutting depth in one feed. However, when using a milling machine to mill spiral grooves on the surface of shaft workpieces, milling Difficulty, long milling time and high milling cost, difficult to guarantee milling accuracy, not suitable for batch processing. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention...
