A spiral bevel gear processing machine tool

Abstract

The invention discloses a spiral bevel gear machining machine tool. The spiral bevel gear machining machine tool comprises a revolving table box and a workpiece box, wherein the revolving table box has a revolving shaft; one end of the revolving shaft is fixedly connected with the workpiece box; the workpiece box has a connecting shaft; and the connecting shaft fixedly coats the revolving shaft. The spiral bevel gear machining machine tool further comprises a static pressure bearing base coating the connecting shaft and fixedly connected with the revolving table box; multiple static pressure oil cavities are distributed between the static pressure bearing base and the connecting shaft in the peripheral direction; and the static pressure bearing base is provided with an oil supply way communicated with each static pressure oil cavity. The structural design of the machine tool can improve the rigidity of the connecting place between the workpiece box and the revolving table box; and when main cutting force is changed along with the rotation of the revolving shaft, the support can be supplied to the workpiece box in the cutting force direction.

Description

technical field [0001] The invention relates to the technical field of numerical control processing equipment, in particular to a spiral bevel gear processing machine tool. Background technique [0002] The existing spiral bevel gear processing equipment mainly includes mechanical spiral bevel gear processing machine tools and numerically controlled spiral bevel gear processing machine tools. Among them, the structure and adjustment of mechanical spiral bevel gear processing machine tools are the most complicated. Therefore, the application of CNC spiral bevel gear processing machine tools is becoming more and more extensive. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of the existing CNC spiral bevel gear processing machine tool. [0004] As shown in the figure, the CNC spiral bevel gear processing machine tool includes a bed 11, an X-axis sliding table 12 that can move along the X-axis direction is arranged on the bed 11, and an X-a...

Problems solved by technology

[0007] The workpiece shaft is installed in the workpiece box, and the workpiece box is suspended and installed on the rotary shaft of the rotary table box. Due to the long overhang, the rigidity is poor and the natural frequency is low. When processing products with large modulus, the overhang Vibration occurs at the place, and finally causes the whole machine tool to resonate

[0008] Although the equipment is provided with a static pressure auxiliary support 16 at the bottom of the workpiece box, the static pressure auxiliary support 16 has only one support point in the entire circumferential direction, and the direction of the main cutting force changes with the rotation of the B axis, so the static pressure auxiliary support 16 16 does not play a supporting role in the direction of cutting force
