Abstract
The utility model discloses a kind of grinding head of polishing machine upper bearing water-tight device.It comprises the main shaft with centre bore and the water inlet pipe extend in spindle hole, sealing ring is provided with between main shaft and water inlet pipe, main shaft is outside equipped with urceolus, two bearings are installed between urceolus and main shaft, it is characterized in that: directly over the bearing of described upper end, be provided with the hermetic unit that urceolus and mainshaft snap can be sealed, the water leg described hermetic unit being provided with annular and the spilled water hole led to outside urceolus.After adopting above-mentioned structure, when cooling water leakage, top sealed portion is thrown in the annular collecting vat of lower seal part, then flows out to outside through spilled water hole, thus avoid cooling water to enter Bearing inner, so just effectively can solve cooling water and enter the problem that Bearing inner causes bearing damage.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of grinding head of polishing machine, particularly a kind of grinding head of polishing machine upper bearing water-tight device.
Background technology
Ceramic tile polisher is mainly used in polished glazed tile surface, and the bistrique top on polishing machine is a vitals; The bistrique top of existing polishing machine has the through hole arranged at the alignment of shafts, cooling water flows through from through hole, because cooling water uses recirculated water usually, containing certain abrasive grain, easily make sealing ring damage to lose efficacy, when the sealing ring between water inlet pipe and main shaft damages, cooling water just leaks out, flow into bearing chamber inside, thus cause bearing also easily to cause damage.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of cooling water that can effectively solve and enters the grinding head of polishing machine upper bearing water-tight device that Bearing inner causes bearing damage problem.
In order to solve the problems of the technologies described above, grinding head of polishing machine upper bearing water-tight device of the present utility model, comprise the main shaft with centre bore and the water inlet pipe extend in spindle hole, sealing ring is provided with between main shaft and water inlet pipe, main shaft is outside equipped with urceolus, two bearings are installed between urceolus and main shaft, directly over the bearing of upper end, are provided with the hermetic unit that urceolus and mainshaft snap can be sealed, water leg hermetic unit being provided with annular and the spilled water hole led to outside urceolus.
Described hermetic unit comprises a top sealed portion and lower seal part, described top sealed portion is pressed over outside main shaft, described lower seal part is placed on the upper surface of urceolus, the bottom of described top sealed portion and the top of lower seal part are provided with the labyrinth structure cooperatively interacted, and water leg and the spilled water hole led to outside urceolus of described annular are arranged in lower seal part.
The upper end of described main shaft is provided with nut, and the lower surface of nut is pressed on the upper surface of top sealed portion, and the bottom of described lower seal part is provided with lower convex platform, and lower convex platform is pressed on the upper surface of upper end bearing.
After adopting above-mentioned structure, owing to being provided with hermetic unit in the upper end of main shaft and bearing, labyrinth seal is adopted between two hermetic units, hermetic unit be provided with annular collecting vat and lead to outside spilled water hole, thus when cooling water leakage, top sealed portion is thrown in the annular collecting vat of lower seal part, then flows out to outside through spilled water hole, thus avoid cooling water to enter Bearing inner, so just effectively can solve cooling water and enter the problem that Bearing inner causes bearing damage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model grinding head of polishing machine upper bearing water-tight device.
Fig. 2 is the structural representation of the hermetic unit that urceolus and mainshaft snap can be sealed.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, grinding head of polishing machine upper bearing water-tight device of the present utility model is described in further detail.
As shown in the figure, grinding head of polishing machine upper bearing water-tight device of the present utility model, comprise the main shaft 1 with centre bore and the water inlet pipe 2 extend in spindle hole, sealing ring 3 is provided with between main shaft 1 and water inlet pipe 2, cooling water can not leak out from sealing ring under normal circumstances, main shaft 1 is outside equipped with urceolus 4, two parts up and down between urceolus 4 and main shaft 1 are separately installed with a bearing 5, the hermetic unit that urceolus and mainshaft snap can be sealed is provided with directly over upper end bearing 5, water leg hermetic unit being provided with annular and the spilled water hole led to outside urceolus, said hermetic unit comprises a top sealed portion 7 and lower seal part 6, and top sealed portion 7 is pressed over outside main shaft 1, can rotate with main shaft, lower seal part 6 is placed on the upper surface of urceolus, and the upper end of lower seal part 6 is also crushed on the below of a gland 8, and water inlet pipe 2 is arranged on gland, forms a closed cavity, the bottom of top sealed portion 7 and the top of lower seal part are provided with the labyrinth structure cooperatively interacted, water leg and the spilled water hole led to outside urceolus of annular are arranged in lower seal part, the upper end of main shaft is also provided with nut, the lower surface of nut is pressed on the upper surface of top sealed portion 7, the bottom of lower seal part is provided with lower convex platform, and lower convex platform is pressed on the upper surface of upper end bearing.
The course of work of the present utility model is: non rotating fixed by urceolus and lower seal part, gland and water inlet pipe mounted thereto, main shaft rotates together with sealing ring with top sealed portion mounted thereto, when sealing ring lost efficacy, cooling water leaks out from sealing ring, flow to the upper surface of top sealed portion, water is thrown in the annular collecting vat of lower seal part by the top sealed portion be rotating, then the spilled water hole in lower seal part is discharged to outside.Because of top sealed portion and sealing portion divide between have labyrinth seal function, cooling water can not flow into Bearing inner, thus avoids damaging bearing, effectively solves cooling water and enters the problem that Bearing inner causes bearing damage.
