The technical solutions in the embodiments of the present invention are described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1:

in order to solve the problem that the grinding fluid leaks along the gap between the rotating shaft and the grinding box in the prior art, the polishing machine for preventing the leakage provided by the embodiment 1 of the utility model comprises a motor 1, a polishing disk 2 and a rotary water tank 3 for collecting the grinding fluid, as shown in fig. 1; the polishing disc 2 is fixedly arranged on the rotating shaft of the motor 1; the surface of the polishing disk 2 faces upwards and is horizontally arranged; the rotation of the rotating shaft of the motor 1 can drive the polishing disc 2 to rotate; the rotary water tank 3 is fixedly arranged on the polishing disc 2; the rotary water tank 3 rotates along with the rotation of the polishing disk 2; the rotating tub 3 includes an opening 31; the plane of the opening 31 is horizontally arranged; the height of the plane of the opening 31 in the vertical direction is lower than the height of the plane of the disk surface of the polishing disk 2.

When the polishing machine for preventing liquid leakage provided by the embodiment 1 of the utility model works, the rotary water tank 3 replaces the function of a grinding box, grinding liquid is arranged in the rotary water tank 3, and the water level of the grinding liquid is higher than the disc surface of the polishing disc 2; the motor 1 and the rotary water tank 3 are not directly connected, the motor 1 drives the polishing disc 2 to rotate, and the rotation of the polishing disc 2 enables the rotary water tank 3 to rotate; so there is no gap between the rotating shaft of the motor 1 and the rotating water tank 3; when the polishing machine works, the polishing disc 2 and the rotary water tank 3 synchronously rotate together; because the rotary water tank 3 is hermetically connected with the polishing disk 2, the rotary water tank 3 and the polishing disk 2 cannot rotate relatively, a gap reserved for ensuring rotation is not reserved at the joint between the rotary water tank 3 and the polishing disk 2, and because the gap for leaking grinding fluid is not reserved, the grinding fluid does not leak from the gap.

The embodiment 1 of the utility model provides a burnishing machine that prevents weeping has solved the problem that the grinding fluid can spill along the clearance between pivot and the grinding case for in the work piece course of working, the grinding fluid can not spill along the pivot and the clearance between the grinding case.

The rotating water tank 3 rotates to drive the grinding fluid to rotate in the rotating water tank 3, the linear speed of the grinding fluid is increased while the angular speed of the grinding fluid is unchanged, the grinding fluid moves towards the outer ring of the rotating water tank 3, when the grinding fluid touches the inner wall of the rotating water tank 3, the kinetic energy can be converted into potential energy after the speed cannot be further increased outwards, the grinding fluid can move vertically upwards, the middle part of the grinding fluid moving upwards can splash out of the rotating water tank 3, and in order to reduce the influence of splashing of the grinding fluid, the grinding fluid spraying device further comprises a water retaining ring 4 capable of absorbing water, and the water retaining ring 4 is fixedly arranged on the opening 31; the water retaining ring 4 is attached to the inner wall of the rotary water tank 3; the position of the water retaining ring 4 is higher than the height of the plane where the disc surface of the polishing disc 2 is located in the vertical direction; the water retaining ring 4 forms an annular shape, and when the grinding fluid flows out of the rotary water tank 3 at the opening 31 by abutting against the inner wall of the rotary water tank 3, the grinding fluid inevitably passes through the water retaining ring 4. After the grinding fluid touches the water retaining ring 4, can be blockked and adsorb by the water retaining ring 4 for the grinding fluid can not splash and go out from rotating basin 3 easily, reduces grinding fluid and scatters, and after the grinding fluid got into other equipment and makes equipment damage, grinding fluid drop make the people slide on the ground, and the grinding fluid drops and produces influences such as short circuit at the power.

Since the workpiece is ground by the polishing disc 2, foreign debris is generated, and the rubber sealing plug commonly used in the prior art may be pierced by the debris; in the embodiment, the device also comprises a plurality of ball valves 5; the rotary water tank 3 is provided with a plurality of liquid discharge holes 32; a ball valve 5 is arranged on each drain hole 32. The polishing quality is reduced because the grinding fluid contains excessive impurity fragments after being used for a period of time; at the moment, the grinding fluid needs to be replaced in time, the grinding fluid can flow out from the position through the arrangement of the drain hole 32, and the ball valve 5 can control the opening and closing of the drain hole 32; compared with a rubber sealing plug, the ball valve does not cause the situation of liquid leakage at the liquid discharge hole 32 caused by the penetration of debris; in this embodiment, as a preferable mode, two drain holes 32 are used, and the two drain holes 32 are symmetrical about the center of the axis of the polishing platen 2; the central symmetry can make the whole device rotate smoothly.

In summary, the utility model discloses a liquid leakage prevention polishing machine, relating to the field of grinding and polishing, comprising a motor, a polishing disk and a rotary water tank for collecting grinding liquid; the polishing disc is fixedly arranged on a rotating shaft of the motor; the disc surface of the polishing disc is horizontally arranged; the rotation of the rotating shaft of the motor can drive the polishing disc to rotate; the rotary water tank is fixedly arranged on the polishing disc; the rotary water tank rotates along with the rotation of the polishing disc; the rotating water tank comprises an opening; the plane where the opening is located is horizontally arranged; the height of the opening in the vertical direction is lower than that of a plane where the surface of the polishing disk is located. The utility model provides a prevent burnishing machine of weeping has solved the problem that the grinding fluid can spill along the clearance between pivot and the grinding case for in the work piece course of working, the grinding fluid can not spill along the pivot and the clearance between the grinding case.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
