Description

Technical Field

[0001] The utility model relates to the technical field of spline shafts, in particular to a spline shaft production slotting machine. Background Art

[0002] The spline shaft is a kind of mechanical transmission. Like the flat key, semicircular key and oblique key, they all transmit mechanical torque. There is a longitudinal keyway on the surface of the shaft, and the rotating part on the shaft also has a corresponding keyway, which can keep rotating synchronously with the shaft. In the process of processing the spline shaft, workers will use a universal lifting table milling machine to process the spline shaft. During processing, a milling cutter is fixed on the tool fixture above the milling machine, and the spline shaft is fixed on the moving table. When the moving table moves to the left, the milling cutter mills a long groove on the spline shaft. After the moving table moves to the left and returns to its position, the worker has to manually turn the upward handle to move the moving table up a distance and perform a second groove milling in the same long groove. When the width and depth of the first groove meet the requirements, manually turn the rotating handle of the spline shaft to mill the next groove until all the grooves on the spline shaft are processed.

[0003] During the machining process, a large amount of metal debris will be scattered around the machine tool, resulting in accumulation. Cleaning work is required after the machining is completed, and the debris is scattered relatively scattered, which is cumbersome to clean up, reducing work efficiency. At the same time, when grooving, most of the shafts are clamped at both ends. The clamping structure of the machine tool can only clamp one end, and the other end is fixed and rotated by the ejector pin structure. When the shaft is long, the grooving will cause the whole to vibrate, resulting in poor grooving accuracy. Therefore, we proposed a spline shaft production grooving machine to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a spline shaft production slotting machine to solve the problems of relatively scattered debris and poor shaft stability of the spline shaft production slotting machine on the current market proposed in the background technology.
