Description

Technical Field

[0001] This utility model relates to the technical field of air bearing processing equipment, specifically to a pressure roller device for an ultra-precision machine air-bearing bearing. Background Technology

[0002] Air bearings (also known as air float bearings) are sliding bearings that use gas (usually air, but other gases may also be used) as a lubricant. Air is less viscous than oil, resistant to high temperatures, and pollution-free, so it can be used in high-speed machines, instruments, and radioactive devices. However, its load capacity is lower than that of oil. Air bearings are divided into three main categories: air static bearings, air hydrodynamic bearings, and extrusion diaphragm bearings. In general industry, air static bearings are more widely used.

[0003] However, the following problems exist in the current production of air bearings: it is not convenient to carry out rapid pressing of the rollers, resulting in low production accuracy, which needs to be improved. Utility Model Content

[0006] The limiting pressure roller structure is used for supporting the air bearing structure and for extrusion work. The threaded spindle is screwed on the nested block to fix the air bearing structure. The electric telescopic rod controls the extension and retraction adjustment of the support bracket to support the air bearing structure. The electric hydraulic rod controls the displacement of the push plate and the push block to extrude the air bearing structure.

[0007] The air bearing structure uses a limiting pressure roller structure to assemble and fix the bearing housing and wheel disc.

[0008] Specifically, the limiting pressure roller structure includes a support bracket, an electrically controlled telescopic rod, a threaded rotating bracket, a nested block, and a support base plate. A nested block is fixedly connected to one side of the support base plate, and a threaded rotating bracket is threadedly connected to the nested block.

[0009] Specifically, an electrically controlled telescopic rod is fixedly installed at the center of the supporting base plate, and a support bracket is telescopically connected to the electrically controlled telescopic rod, and the support bracket has an arc-shaped design.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By installing a limiting pressure roller structure, the extrusion process of the air bearing structure is facilitated. The nested block is equipped with a threaded rotating frame, which can limit the extrusion of the air bearing structure. The electric telescopic rod controls the lifting and adjustment of the support bracket to provide bottom support for the air bearing structure. The electric hydraulic rod controls the pushing plate and the pushing block to push and adjust, thereby driving the wheel to extrude through the pushing plate and the pushing block, which facilitates the cooperation with the rotating shaft on the bearing seat.
