Embodiment Construction

[0011] specific implementation

[0012] The following is an example of a commonly used 165 spline shaft processing technology:

[0013] 1. Make the blank first, adjust the process according to the above requirements, the focus is to improve the manufacturing accuracy of the mold, meet the requirements of the machining allowance, adjust the outer circle and length size, the outer circle size has reached Ф27.5, after processing The size is Ф27.

[0014] 2. Quenching and tempering the modified blank, focusing on controlling the placement of the workpiece during the heating process, the way of oiling during the quenching and tempering process, and using special tooling and fixtures to prevent deformation. In this process, the straightness requirement should not exceed 0.3.

[0015] 3. Punch the center hole at both ends of the quenched and tempered blank, place it on the cylindrical grinder, and grind it to the size of the outer circle Ф27.5.

[0016] 4. Mill the spline on the sp...

Abstract

The invention provides a manufacturing technology of a spline shaft and has the following characteristics: manufacturing a blank, adjusting the sizes of the excircle and the length, the size of the excircle is Phi 27.5 and the size after processing is Phi 27; hardening and tempering the altered blank, focally controlling the layout of workpieces in the heating process and the oil introducing manner in the hardening and tempering process, adopting the dedicated tooling and fixture to prevent deformation, controlling the straightness accuracy to be less than 0.3; punching central holes at two ends of the blank which is hardened and tempered to place on a cylindrical grinding machine, grinding until the excircle size is Phi 27.5; milling the splines on a spline milling machine after mass grinding to an extent that the surface is smooth and level after milling. The technology leaves out two working procedures, improves efficiency when lowering the cost simultaneously. Integrated with various proposals, the technology is workable and scientific.

Description

technical field [0001] The invention relates to the spline shaft manufacturing process in the transmission shaft industry, transforms the traditional processing technology, and uses advanced and fast grinding technology. Background technique [0002] The spline shaft is a general-purpose component in the transmission shaft industry, and is widely used in the connection of transmission parts of various transmission shafts. For many years, its manufacturing and processing technology has been following the traditional process of rough rough and finish turning and then milling splines. low efficiency. In order to reduce the cost, under the current market conditions, the traditional processing technology must be changed for mass production, so we have improved its manufacturing process. Contents of the invention [0003] The purpose of the present invention is to change the traditional manufacturing process and effectively reduce the manufacturing cost. The specific content is...
