Embodiment Construction

[0031] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0032] refer to figure 1 and figure 2 , a device for hobbing at both ends of the spline shaft, including:

[0033] A spindle clamping mechanism, which clamps the workpiece to be processed,

[0034] A positioning proofreading device, used to ensure the positioning accuracy of the workpiece to be processed after the direction is reversed,

[0035] The positioning and checking device includes: a center frame base 1, a bracket 3 that can move linearly on the bottom plate 2 and the first guide key 13, and is used for adjusting the macroscopic distance of workpieces with different diameters. After adjustment, it is pressed with bolts 11.

[0036] The adjustment frame 4 is a weldment, which can move linearly on the support 3 and the second guide ke...

Abstract

The invention discloses a spline shaft two-end rolling milling device and a processing method thereof. The device comprises a main shaft fixture mechanism used for fixing a workpiece requiring processing, and a positioning correction device used for ensuring the positioning precision of the workpiece requiring processing after direction turning. The method comprises the steps that: 1, the workpiece requiring processing is inserted from a spline milling machine head main shaft hole; with the main shaft fixture mechanism, the workpiece is firmly fixed, and rolling milling is carried out; 2, with the semi-finished product processed by the step 1, the position of the positioning correction device is adjusted and determined, and the positioning correction device is fixed; 3, the semi-finished processed product is detached, and the position is turned; the part with rolling milling finished is placed into the positioning correction device and is fixed; and 4, the semi-finished processed product obtained in the step 3 is firmly fixed, the positioning mechanism of the positioning correction device is detached, and milling of the part with rolling milling unfinished is proceeded. With the device and method provided by the invention, machine tool processing range is doubled, such that the difficulty for processing a 1200mm-long spline by using a common Y631K spline shaft milling machine is solved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a device and a processing method for hobbing two ends of a spline shaft. Background technique [0002] Using the existing Y631K spline shaft milling machine, only the spline shaft within 600mm can be processed, once the spline shaft exceeding 600mm is required, it cannot be produced. [0003] Change the usual one-time hobbing and milling processing method in the manufacture of spline shafts, and cooperate with special tooling accessories to realize the processing of long spline shafts in the overtravel range. [0004] Through trial production, it is equipped with a special positioning and checking device, and adopts the processing method of hobbing and milling at both ends, so that the existing Y631K spline shaft milling machine can only process spline shafts within 600mm in the past, but now it can hob and process spline shafts within 1200mm in length. The spline shaft doub...
