Embodiment Construction

[0023] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0024] The single-axis dynamic sealing device used for casting CNC machine tools is characterized in that the device is composed of a base 1, a guide rail 2, a dust-proof structure, and a sliding mechanism. The dust-proof structure is composed of a metal cover 4 and an organ cover 5, the base 1 is fixed, the guide rail 2 is fixed on the base 1, the slider 3 and the guide rail 2 form a sliding pair, and the connecting block 6 is connected with the guide rail. Realize the reciprocating movement of the connecting block 6 along the direction of the guide rail 2, one side of the organ cover is connected with the base 1, and one side is connected with the connecting block 6, and the organ cover can freely shrink as the connecting block moves back and forth, so Said metal cover 4 is fixed with the base 1, and the periphery is all sealed with the base.

Abstract

The invention relates to a dynamic sealing device for a single shaft of a casting mold numerical control machine. A metal cover and an organ cover are combined, and a double-layer protective mode is adopted, thus an excellent dust-proof effect can be achieved. In the device provided by the invention, components such as a guide rail, a screw rod and the like through which dust can invade the interior of a motive system are omitted, and the service life of the device is improved; and the device has the advantages of simplicity and convenience in installation, convenience in maintenance, capability of adapting to the severe environment with high content of dust, and the like.

Description

technical field [0001] The invention relates to a structure and a device for sealing and dustproofing a motion system used for casting mold processing, and belongs to the field of special processing machine tool accessories. Background technique [0002] Sealing is a measure to prevent fluid or solid particles from leaking from adjacent joint surfaces and to prevent external impurities such as dust and moisture from intruding into precision parts in machinery and equipment. Its basic requirements are good sealing, safety and reliability, and long life. It should be compact in structure, simple in system, convenient in manufacture and maintenance, and low in cost. [0003] At present, dynamic seals can be divided into two basic types: rotary seals and reciprocating seals. But in all the sealing structures of the motion system, most of them are the seal between the shaft and the hole, and this motion is a rotary motion, or a short-distance cylindrical reciprocating motion. I...
