Abstract
The utility model relates to a principal axis waterproof and dustproof device of an eccentric sleeve of a dynamic-static pressure grinding head, comprising a box body 1, a bolt 2, a ring flange 3, a seal ring 4, 5, a bolt 6, an eccentric ring flange 7, a grinding wheel component 8, a ring flange 9, an eccentric sleeve 10, a bearing 11,13 and a principal axis 12. The box body 1 is connected with the ring flange 3 by the bolt; the seal ring is connected with the eccentric ring flange 7; the eccentric ring flange is connected with the box body by the bolt 6; clearance exists between the eccentric ring flange and the box body; the grinding wheel component 8 is connected with the ring flange 9 which is connected with the eccentric sleeve 10; the eccentric sleeve is connected with the bearing 11,13; clearance exists between the eccentric sleeve 10 and the ring flange 3; and the bearing 11 is connected with the principal axial 12. The eccentric sleeve drives the eccentric ring flange, which is eccentric with the eccentric sleeve and is provided with the seal ring, to be sealed along with the rotation around the ring flange; the clearance between the eccentric sleeve and the ring flange is separated from outside completely; grinding liquid and sand grains are prevented form entering the box body from the clearance; consequently, the seal of the dynamic-static pressure grinding head is realized.
Description
Technical field
The utility model relates to high-accuracy roll grinder technology, prevents to sneak in the hydraulic oil the anti-water dust device of a kind of grinding dynamic and static pressure grinding wheel head eccentric bushing main shaft that water and sand and dust enter casing when being specifically related to the roll grinder grinding
Background technology
In the prior art, the grinding dynamic and static pressure grinding wheel head of high-accuracy roll grinder generally adopts eccentric structure, and the grinding head grinding wheel end has only simple seal approach or do not adopt seal approach; Therefore, dust, the sand grains that produces in grinding fluid and the grinding during grinding can enter into grinding head box body from the grinding head grinding wheel end; Grinding fluid and dust can enter again in the interior hydraulic oil of grinding head box body simultaneously, cause hydraulic oil to be scrapped, the accident that causes grinding dynamic and static pressure grinding wheel head to work; In addition, in a single day the dust that produces during grinding, sand grains enter the grinding dynamic and static pressure grinding wheel head bearing, and easier grinding hindered bearing, so that cause bistrique to scrap.
Summary of the invention
Main purpose of the present utility model is to improve at problems of the prior art, design provides a kind of eccentric flange dish and sealing ring of utilizing to carry out Follow-up seal, increase sealing device at grinding head box body emery wheel end, just can prevent fully that grinding fluid and sand dust from entering grinding head box body, realize the sealing of grinding dynamic and static pressure grinding wheel head.
For realizing described purpose, the technical solution of the utility model is: the anti-water dust device of grinding dynamic and static pressure grinding wheel head eccentric bushing main shaft comprises casing (1), screw (2), ring flange (3), sealing ring (4), (5), screw (6), eccentric flange dish (7), emery wheel assembly (8), ring flange (9) eccentric bushing (10), bearing (11), (13), main shaft (12) is formed; Described casing (1) is connected with screw (2) with ring flange (3), sealing ring (4) and sealing ring (5) are connected with eccentric flange dish (7), eccentric flange dish (7) is connected on the casing (1) by screw (6), emery wheel assembly (8) is connected with ring flange (9), ring flange (9) is connected with eccentric bushing (10), eccentric bushing (10) is connected with bearing (11), (13), and bearing (11) is connected with main shaft (12).
Between described eccentric flange dish (7) and the casing (1) certain interval is arranged;
Between described eccentric bushing (10) and the ring flange (3) certain interval is arranged;
The O RunddichtringO can be adopted in described sealing ring (4), (5), also can adopt the sealing ring of other form.
The beneficial effects of the utility model are: improve simple in structure, reasonable in design, fitting operation is convenient, efficiently solves the sealing of high-accuracy roll grinder grinding dynamic and static pressure grinding wheel head, avoided hindering the grinding dynamic and static pressure grinding wheel head bearing or scrapping the bistrique that hydraulic oil causes and scrap, guaranteed the operate as normal of bistrique owing to grinding.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described;
With reference to Fig. 1, Fig. 2, the anti-water dust device of grinding dynamic and static pressure grinding wheel head eccentric bushing main shaft is made up of casing 1, screw 2, ring flange 3, sealing ring 4, sealing ring 5, screw 6, eccentric flange dish 7, emery wheel assembly 8, ring flange 9, eccentric bushing 10, bearing 11, main shaft 12, bearing 13; Its casing 1 is linked together ring flange 3 by screw 2, sealing ring 4 is connected eccentric flange dish 7 with sealing ring 5, eccentric flange dish 7 is connected on the casing 1 by screw 6, and make between eccentric flange dish 7 and the casing 1 certain interval is arranged, emery wheel assembly 8 mounting flanges 9, ring flange 9 connects eccentric bushing 10, eccentric bushing 10 connection bearings 11 and bearing 13, between eccentric bushing 10 and the ring flange 3 certain interval is arranged, bearing 11 connects main shaft 12.Its sealing ring 4,5 can adopt the O RunddichtringO, also can adopt the sealing ring of other form.
Its operation principle is: during use, utilize eccentric flange dish and sealing ring to carry out Follow-up seal, set up sealing device at grinding head box body emery wheel end; The eccentric flange dish 7 that drives identical off-centre with it and sealing ring 4,5 is housed when being rotated by eccentric bushing 10 has guaranteed that around ring flange 3 servo-actuated rotary seals the gap of eccentric bushing 10 and ring flange 3 is isolated from the outside fully; Thereby effectively prevented, thereby reach the purpose that grinding dynamic and static pressure grinding wheel head can seal from the grinding fluid and the sand grains that enter casing 1 between the gap.
