Universal joint oil groove milling machine of machine tool

Abstract

The invention discloses a universal joint oil groove milling machine of a machine tool. Four groups of milling cutters and driving mechanisms of the milling cutters are symmetrically arranged on a square worktable. The universal joint oil groove milling machine mainly comprises a frequency-converting motor, a passing belt pulley, a main shaft box and the milling cutters which are independently driven and arranged at the end part of the main shaft box, wherein the milling cutter comprises three milling blades which are alternated at equal distance; the center connecting line of the three milling blades is in a cross shape; an electric appliance control cabinet and a main air cylinder are arranged below the worktable; the main air cylinder is connected with a positioning block arranged at the upper part of the main air cylinder through a guide sleeve by a pull rod of the main air cylinder; a crossed V-shaped groove is arranged in the positioning block; and a square hole is arranged in a central area of the worktable, so that the positioning block drives the universal joint (workpiece) at the upper part of the positioning block to be driven by the main air cylinder to do the up-down movement in due time and finish milling. In addition, the bracket is arranged on the positioning block; and a clamping air cylinder is arranged on the bracket.

Description

technical field [0001] The invention relates to a mechanical processing machine tool, in particular to a machine tool cross-axis milling and cutting oil groove machine, which belongs to the technical field of machine tool processing. Background technique [0002] In order to improve the oil storage capacity between each shaft head and the shaft sleeve of the universal joint cross shaft and reduce the frictional resistance of movement, it is necessary to mill out several oil grooves on each end surface of the cross shaft. The existing method of manufacturing oil grooves uses a milling machine on the cross shaft. Several oil grooves are milled out one by one on each end face of the shaft head. Therefore, there are defects such as low production energy efficiency, low equipment utilization efficiency, and high processing cost of the product. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a ma...
