Problems solved by technology

[0002] The rigidity of slender shaft parts is poor, and it is easy to generate vibration during processing, and the processing accuracy is difficult to guarantee. The traditional technology is to disperse the various processing procedures of slender shafts to machine tools with different processing capabilities (such as ordinary cars, CNC machines, etc.) lathe, grinding machine and vertical machining center, etc.), the disadvantage of this processing method is that the process is cumbersome, takes up more equipment, each process is secondary clamping, the positioning reference is not easy to guarantee, and the technical The level requirements are high, and it is difficult to guarantee the processing dimensional accuracy

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, the main body of the processing equipment used in the present invention is a milling-turning (or turning-milling) compound machining center, and the processing equipment is provided with a chuck 1, a movable tool rest 2, a hydraulic tailstock 3 and a center frame 4, and in the center The frame 4 is provided with two auxiliary supporting jaws. During processing, one end of the workpiece is supported by the top of the hydraulic tailstock 3, and the other end of the workpiece is clamped by the chuck 1 and driven to rotate. The movable tool rest 2. It has three degrees of freedom of movement in the directions of X, Y, and Z. Various processing tools are installed on the movable tool rest 2, and the center frame 4 is arranged under the movable tool rest 2. The drive moves along the Z direction, thereby driving the two auxiliary s...

Abstract

The invention relates to the field of mechanical machining, in particular to a long and thin shaft part machining technology. Machining equipment is provided with a chuck, a moving cutter frame, a hydraulic tailstock and a center frame capable of moving in the axial direction of a workpiece. A machining cutter tool is installed on the moving cutter frame. The center frame is arranged below the moving cutter frame. The workpiece is arranged between the moving cutter frame and the center frame during being machined. The workpiece is fixed through the hydraulic tailstock and the chuck. The center frame is provided with two auxiliary supporting clamping claws. Workpiece machining includes shaft surface machining and hole machining. According to the long and thin shaft part machining technology, workpiece clamping is assisted at an appropriate position by utilizing the two auxiliary supporting clamping claws, thus all machining processes are completed through once installing and clamping, intermediate machining links are reduced, and meanwhile, the machining precision is also effectively guaranteed.
