Embodiment Construction

[0011] specific implementation plan

[0012] Such as figure 1 Shown, the present invention is a kind of device that utilizes steel ball to inner hole finish machining, and it comprises hydraulic machine 1, hydraulic head 2, fixture 5 and hydraulic table 6, and the middle position of described hydraulic machine 1 is equipped with hydraulic head 2; A fixture 5 is installed on the working surface of the hydraulic table 6, corresponding to the hydraulic head 2; the stamping end of the hydraulic head 2 is an inwardly concave arc, which matches the curvature of the surface of the steel ball 3; the fixture 5 is hollow and concave. The font is beneficial to the placement of the workpiece 4 and the extruding work of the steel ball 3.

[0013] The inside of the hydraulic table 6 is equipped with a hydraulic gauge and a motor, which are the power control of the hydraulic head 2 .

[0014] When working, put the workpiece 4 flat in the special fixture 5, then put the steel ball 3 in the ...

Abstract

The invention relates to a device for machining an inner hole, in particular to a device for finish machining of an inner hole by means of a steel ball. The device comprises a hydraulic machine 1, a hydraulic head 2, a fixture 5 and a hydraulic table 6, wherein the hydraulic head 2 is installed in the middle of the hydraulic machine 1; the fixture 5 is installed on a working surface of the hydraulic table 6 and corresponds to the hydraulic head 2; a stamping end of the hydraulic head 2 is an inward concave circular arc and is fit with the surface of the steel ball 3 in radian; the fixture 5 is of a shape like the Chinese character 'ao' hollow in the middle, and facilitates placement of a workpiece 4 and extrusion for the steel ball 3. The requirement of original fine boring for a cutter and a machine tool is replaced, the machining number in unit time is higher than that of fine boring by one time, quality, especially roughness, of a machined product is higher than that of fine boring, and the yield and production benefits are increased.

Description

technical field [0001] The invention relates to an inner hole machining device, more precisely a device for finishing inner holes by using steel balls. Background technique [0002] The gear is an important part for transmitting motion and power in the machine, so the accuracy of the gear determines the accuracy and stability of its transmission. Because the finishing of the gear in the later stage is mostly positioned by the inner hole, the accuracy of the inner hole of the gear has the most important effect on the accuracy of the gear. critical use. The traditional gear inner hole processing adopts three-jaw chuck to clamp the outer circle for positioning, and the precision and roughness requirements are guaranteed through the processing technology of fine boring. To ensure the roughness, the efficiency generated per unit time is very limited. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages mentioned above and pro...
