Abstract
A motor water-stop structure in a three-phase machine tool cooling pump comprises a pump shaft and a water-stop ring, wherein the water-stop ring sleeves the pump shaft, the water-stop ring is shaped like a cone frustum, more than two convex reinforced ribs are distributed uniformly on the conic face of the water-stop ring at an interval, and any of the reinforced ribs is extended to the outer circumference of the water-stop ring from the inner circumference of the water-stop ring; the reinforced ribs are extended along the straight line direction; when the cooling pump is operated, the water-stop ring is rotated synchronously with the pump shaft, leaked cooling liquid is blocked by the water-stop ring when rising along a spindle, the flowing speed of the cooling liquid on the conic face of the water-stop ring is reduced by blocking of the reinforced ribs and thrown away by centrifugal force of the water-stop ring and then returns to a cooling liquid tank, so the cooling liquid is prevented from entering the motor along the spindle, which can cause the motor burning; and the water-stop ring is fixed with the pump shaft by a positioning pin, avoiding sliding of the water-stop ring during operation.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to three-phase machine tool cooling pump, particularly a kind of motor water-retaining structure for three-phase machine tool cooling pump.
Background technique:
Three-phase machine tool cooling pump is combined into an integral body by motor and the centrifugal pump of vertical installation conventionally, is applicable to 50Hz or 60Hz, and the arbitrary frequency of 220～250V or 380～440V and arbitrary voltage can be done circulation cooling lubrication liquid for lathe or other equipment.Conventionally the whole aluminum alloy that adopts is cast, lightly durable, the advantage such as have beautiful outline form, volume is little, lightweight, noise is low and overload capacity is strong.During three-phase machine tool cooling pump operation, cooling liquid often enters motor internal after rotating shaft is climbed, and affects motor and normally works.
Summary of the invention:
The purpose of this utility model is to provide a kind of motor water-retaining structure for three-phase machine tool cooling pump, and the described this motor water-retaining structure for three-phase machine tool cooling pump will solve the technical problem that prior art cooling liquid enters motor internal after rotating shaft is climbed.
This motor water-retaining structure for three-phase machine tool cooling pump of the present utility model, comprise a pump shaft and a water holding ring, described water holding ring is set on described pump shaft, wherein, described water holding ring is circular cone shape, in the lower end surface of water holding ring, be coaxially arranged with a cylindrical tube downwards, in the tube wall of described cylindrical tube, be disposed radially positioning pin hole, in described positioning pin hole, be provided with locating stud, one end of described locating stud is along the radially insertion pump shaft of pump shaft, on the conical surface of water holding ring, be evenly intervally distributed with the protruding stiffening rib of two above numbers, stiffening rib described in any one all extends to the excircle of water holding ring from the inner circumference of water holding ring.
Further, the stiffening rib described in any all extends along rectilinear direction.
Working principle of the present utility model is: during coolant pump operation, water holding ring is with pump shaft synchronous rotary, when the cooling liquid of leaking is climbed along rotating shaft, by water holding ring, stopped, the flowing velocity of cooling liquid on the conical surface of water holding ring is subject to the barrier effect of stiffening rib and reduces, under the effect of water holding ring centrifugal force, thrown away, got back in tank for coolant, thereby avoided cooling liquid to enter motor internal along rotating shaft, caused burn-down of electric motor; Water holding ring is fixed by locating stud and pump shaft, while having avoided water holding ring operation, skids.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model arranges locating stud between water holding ring and pump shaft, while having avoided water holding ring operation, skids.On the conical surface of water holding ring, protruding reinforcing rib is set, when the cooling liquid of leaking is climbed along rotating shaft, the flowing velocity of cooling liquid on the conical surface of water holding ring is subject to the barrier effect of stiffening rib and reduces, under the effect of water holding ring centrifugal force, thrown away, get back in tank for coolant, thereby avoided cooling liquid to enter motor internal along rotating shaft, cause burn-down of electric motor.

Embodiment:
Embodiment 1:
As Fig. 1, shown in Fig. 2 and Fig. 3, motor water-retaining structure for three-phase machine tool cooling pump of the present utility model, comprise a pump shaft 1 and a water holding ring 2, described water holding ring 2 is set on described pump shaft 1, wherein, described water holding ring 2 is circular cone shape, in the lower end surface of water holding ring 2, be coaxially arranged with a cylindrical tube downwards, in the tube wall of described cylindrical tube, be disposed radially positioning pin hole 4, in described positioning pin hole 4, be provided with locating stud 3, one end of described locating stud 3 is along the radially insertion pump shaft 1 of pump shaft 1, on the conical surface of water holding ring 2, be evenly intervally distributed with the protruding stiffening rib 5 of two above numbers, stiffening rib 5 described in any one all extends to the excircle of water holding ring 2 from the inner circumference of water holding ring 2.
Further, the stiffening rib 5 described in any all extends along rectilinear direction.
The working principle of the present embodiment is: during coolant pump 6 operation, water holding ring 2 is with pump shaft 1 synchronous rotary, when the cooling liquid of leaking is climbed along rotating shaft, by water holding ring 2, stopped, the flowing velocity of cooling liquid on the conical surface of water holding ring 2 is subject to the barrier effect of stiffening rib 5 and reduces, under the effect of water holding ring 2 centrifugal force, thrown away, got back in tank for coolant, thereby avoided cooling liquid to enter motor 7 inside along rotating shaft, cause motor 7 to burn; Water holding ring 2 is fixing with pump shaft 1 by locating stud 3, while having avoided water holding ring 2 operation, skids.
