Problems solved by technology

[0005] The invention solves the defect that the contact surface is easy to wear due to the direct mechanical contact between the working platform and the supporting part in the prior art, and provides a hydrostatic workbench of a forming gear grinding machine, in which an oil pipe connected to the contact surface is provided in the supporting part. Road, and the pressure oil is passed to the contact surface to form an oil film on the contact surface, separating the two parts, reducing rotational fric

Example Embodiment

[0021] Example: A static pressure table of a gear grinding machine (see attached figure 1 ), including the housing 4, the housing is a U-shaped rotating body that rotates around an axis parallel to the U-shaped side, the U-shaped wall inside the housing is the inner support 3, and the U-shaped wall outside is the outer support 1. The height of the inner support part is smaller than the outer support part. A working platform 23 is fixed on the upper surface of the housing, a tapered column 17 is arranged in the middle of the working platform, and the middle of the tapered column is a circular hole. A tapered sleeve 18 is provided between the tapered column and the inner side wall of the inner support portion. One end of the tapered sleeve is a tapered hole 14 matching the outer wall of the tapered column, and the other end of the tapered sleeve is provided with a vertical eversion flange. 7. The reverse flanging hooks the bottom surface of the shell. An adjustment pad 6 is arr...

Abstract

The invention relates to a static pressure workbench for a forming gear grinding machine, which solves the defects that the workbench in the prior art is directly and mechanically contacted with supporting components so as to easily cause wear on the contact surface. The static pressure workbench comprises a shell and a workbench, wherein the workbench is arranged on the shell and supported by the shell, a taper sleeve is arranged in the shell and provided with a taper hole, a tapered column is arranged in the middle of the workbench and inserted in the taper hole, a pressure plate with a flanging is fixed at the end part of the tapered column, and the taper sleeve is clamped by the flanging and the shell; and the shell is internally provided with an oil duct which is communicated with the contact surface between the shell and the workbench, the taper sleeve is internally provided with an oil duct which is communicated with the contact surfaces between the taper sleeve and the workbench, as well as the taper sleeve and the pressure sleeve, and oil films are formed on the contact surfaces. The workbench and the shell are in oil film contact, and the oil films include an axial bearing oil film and a radial balance oil film, thus improving the bearing capability and radial adjustment capability, and improving the radial automatic adjustment capability of the workbench.

Description

Technical field [0001] The invention relates to a working table on a gear grinding machine, in particular to a static pressure working table of a gear grinding machine with pressure oil to form an oil film through the bonding surface between the working platform and a supporting part, reducing friction and improving dynamic accuracy . Background technique [0002] The rotary table is a mechanical automation equipment carried by a rotary working platform. The rotary table is used for high precision, high rigidity and heavy load required in the manufacture of small and medium-sized precision metal cutting machine tools and navigation, aerospace, large aircraft, and large power generation equipment. Large-scale technical equipment. Especially important technical equipment in precision mother machines such as high-precision vertical lathes, vertical grinders, counter grinders, and horizontal boring and milling machines. [0003] When the profile grinding machine is working, the workt...
