Problems solved by technology
[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 the 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 Each end face of the head mills out several oil grooves one by one, so there are defects of low production energy efficiency, low equipment utilization efficiency, and high product processing cost

Disclosed is a pneumatic machine tool mechanism for milling oil grooves on a universal joint. Four groups of milling cutters and driving mechanisms of the milling cutters are symmetrically arranged on a quadrangular work table, wherein each driving mechanism of each milling cutter comprises a variable frequency motor, a belt pulley and a spindle box and drives the milling cutter at the end of the spindle box separately, the milling cutter is formed by three milling blades arranged at an equal interval, and the central line connection of the three blades is in a cross type. An electric control cabinet and a main cylinder are arranged under the work table, the main cylinder is connected with a positioning block arranged above through a pull rod of the main cylinder and a guide sleeve, wherein a cross V-type groove is arranged in the positioning block; and a square hole is arranged in the central area of the work table so as to enable the positioning block to drive the cross universal joint (workpiece) arranged above the positioning block to move vertically in due time under the drive of the main cylinder and finish the milling. Additionally, a support is arranged on the positioning block and a clamp cylinder is arranged on the support.
Description
technical field [0001] The invention relates to a machine tool mechanism for milling and cutting oil grooves, in particular to a mechanism for a pneumatic cross-axis milling and cutting oil groove machine tool, which belongs to the technical field of cross-axis processing machine tools. 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 the 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 head. Therefore, there are defects such as low production energy efficiency, low equipment utilization efficiency, and high product processing cost. Contents of the invention [0003] The purpose of the present invention is to overcome the d...
