Embodiment Construction

[0030] The object of the present invention is achieved by the following examples.

[0031] A. Cross shaft positioning and clamping, fix the support seat at the center of the bed table, and fix four V-shaped groove positioning blocks arranged in a cross shape on the support seat. The intersection of the center lines of the V-shaped grooves is 90°±0.1, and the cross shaft After entering, the self-centering is positioned in the four V-shaped grooves, and then a hydraulic cylinder is used to drive the clamping device on the cross shaft to press and fix the cross shaft.

[0032] B. The rotation of the main shaft is controlled by a frequency conversion servo motor, which can realize stepless speed regulation, so as to meet the changing requirements of different main shaft rotation speeds for milling and drilling. A cutter head is fixed on the main shaft, and a milling cutter and a center drill are installed on the main shaft cutter head. Motor Fixed on the horizontal guide rail, the...

Abstract

The invention relates to a technological method of a clamping device of a multi-position cross-shaft processing machine, by adopting the cross-shaft V-shaped slot positioning technology, milling and drilling tools are mounted on four rotating main shafts, the rotating main shafts are fixed on a workbench which can move left, right, frontward and backward, by utilizing the movement of the rotatingmain shafts, four end surfaces of the cross-shaft are firstly simultaneously milled, then the workbench is automatically returned onto a central line of the V-shaped slot, the four main shafts are simultaneously near to the cross-shaft, and four central holes are drilled on the cross-shaft at one time, thereby completing the processing of the end surfaces of the cross-shaft and the central holes on one working procedure at one time. The technological process comprises the following steps of: sawing-forging-milling-drilling-turning a shaft neck-thermal treatment-shot blasting-grinding the shaftneck-defect detection-inspection-packaging and warehousing, thereby not only reducing the processing working procedure of the cross-shaft, reducing the work time and the cost, reducing the labor intensity, improving the processing working efficiency by nearly 10 times, and saving the energy consumption by more than 60%, but also ensuring the concentricity and the vertical degree of the cross-shaft, realizing high processing precision and high qualified rate of the cross-shaft product.

Description

technical field [0001] The invention relates to a process method for positioning and clamping of mechanical processing equipment, in particular to a process method for fixing a cross-axis processing device in a multi-station cross-axis processing machine. Background technique [0002] In the world's economically developed countries, the automobile industry is a pillar industry and a leading industry in the industrial industry. With the rapid development of my country's economy and the continuous improvement of people's living standards, the annual gross production value of the automobile industry occupies a considerable proportion in GDP, which plays a pivotal role in the development of my country's national economy. The car differential is an important mechanical device for the car to turn, and the cross shaft is an important part in the car differential. Its quality level is related to whether the car differential can quickly, flexibly and reliably realize the car. Turnin...
