Abstract
The utility model provides a multi-shaft drill power head dustproof ring which is integrally formed and made of elastic rubber; the inner side surface is an arc surface protruding outwards; two mounting ribs are formed on the outer side surface, and mounting grooves are formed between the mounting ribs; the outer side surfaces of the two mounting ribs are inclined surfaces. The utility model has the advantages that: when the dust ring provided by the utility model is installed, a clearance fit installation mode is adopted between the dust ring and the bearing seat or the box body, and the dust ring is an elastic rubber body and can be tightly wrapped on the outer surface of the drill spindle; when the drill spindle rotates, the dust ring rotates along with the drill spindle, the dust ring and the drill spindle are relatively static, only axial back-and-forth friction exists between the dust ring and the drill spindle, abrasion is greatly reduced, when the drill spindle rotates at a high speed, dust can be thrown away by strong centrifugal force and wind power, and due to the fact that the installation groove is formed in the outer ring of the dust ring, the dust is prevented from entering the bearing and the gear box cavity, and a good dustproof effect is achieved.
Description
Technical Field
The utility model belongs to the technical field of machining equipment, specifically belong to a multi-axis drill unit head dust ring.
Background
When the multi-shaft drill power head works, the drill shaft rotates at a high speed and simultaneously has axial reciprocating motion, and the dustproof structure of the multi-shaft drill power head in the prior art is that a dustproof ring is fixed on a bearing seat or a box body; therefore, the drill shaft and the dust ring have both rotary friction and axial reciprocating friction, the dust ring is easy to wear, dust failure is caused, the wear of an internal bearing is aggravated, and the use of the multi-shaft drill power head is influenced.
Disclosure of Invention
The utility model provides a multi-axis drill unit head dust ring to reach reducing wear, increase of service life makes multi-axis drill unit head job stabilization's purpose.
A multi-shaft drill power head dustproof ring is characterized in that the dustproof ring is integrally formed and made of elastic rubber; the inner side surface is an arc surface protruding outwards; two mounting ribs are formed on the outer side surface, and mounting grooves are formed between the mounting ribs; the outer side surfaces of the two mounting ribs are inclined surfaces.
Furthermore, in the mounting rib, a chamfer is formed except the outer edge of the mounting groove.
The utility model has the advantages that:
when the dust ring provided by the utility model is installed, a clearance fit installation mode is adopted between the dust ring and the bearing seat or the box body, and the dust ring is an elastic rubber body and can be tightly wrapped on the outer surface of the drill spindle; when the drill spindle rotates, the dust ring rotates along with the drill spindle, the dust ring and the drill spindle are relatively static, only axial back-and-forth friction exists between the dust ring and the drill spindle, abrasion is greatly reduced, when the drill spindle rotates at a high speed, dust can be thrown away by strong centrifugal force and wind power, and due to the fact that the installation groove is formed in the outer ring of the dust ring, the dust is prevented from entering the bearing and the gear box cavity, and a good dustproof effect is achieved.
Drawings
Fig. 1 is a schematic structural view of a dust ring provided by the present invention;
FIG. 2 is a schematic view of the installation structure of the middle dust ring of the present invention;
FIG. 3 is a schematic sectional view taken along line A-A of FIG. 2;
FIG. 4 is an enlarged view of the structure enclosed in FIG. 3;
