Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 1-2 This embodiment provides the following technical solution: an internal circumferential tooth polishing wheel, including a polishing wheel body 100, a mounting hole 101 at the bottom of the polishing wheel body 100, a cooling chamber 102 at the top of the polishing wheel body 100, and a plurality of spaced water outlet grooves 103 on the side wall of the cooling chamber 102. Through the provided cold water chamber and water outlet grooves 103, during the high-speed polishing process of the polishing wheel body 100, under the action of centrifugal force, the cooling water in the cooling chamber 102 is discharged from the cooling chamber 102 along the water outlet grooves 103, which plays a guiding role for the cooling water, so as to more effectively reach the area that needs to be cooled, thereby achieving better cooling and better polishing.

[0029] In some embodiments, the water outlet 103 can be a straight groove, an inclined groove, or a spiral groove structure. The structure of the water outlet 103 can be changed according to the polishing requirements of the polishing wheel body 100 to improve the efficiency of cooling water discharge from the cooling chamber 102, better guide the cooling water, and cool the contact surface between the polishing wheel body 100 and the glass.

[0030] Example 2

[0031] like Figures 3-6 As shown, it also includes a disassembly and assembly mechanism 200 for quick disassembly and assembly of the polishing wheel body 100. The disassembly and assembly mechanism 200 includes a positioning plate 201, a plug-in plate 202, and a drive plate 203. The positioning plate 201 is disposed in the cooling cavity 102 and is fixedly connected to the plug-in plate 202. The bottom end of the plug-in plate 202 passes through the mounting hole 101 and is detachably connected to the drive plate 203. The top end of the drive plate 203 is provided with a positioning cavity 204. The bottom end of the drive plate 203 is fixedly connected to the output shaft 300 of the polishing equipment. With the joint cooperation of the positioning plate 201, the plug-in plate 202, and the drive plate 203, the polishing wheel body 100 is clamped and fixed. Under the action of the output shaft 300 of the polishing equipment, the drive plate 203 drives the clamped and fixed polishing wheel body 100 to rotate, so that the polishing wheel body 100 polishes the glass.

[0032] In some embodiments, the diameters of the positioning plate 201 and the drive plate 203 are larger than the diameter of the mounting hole 101, so that the polishing wheel body 100 can be clamped and fixed during the process of clamping the positioning plate 201 and the drive plate 203 up and down.

[0033] Multiple locking mechanisms 400 are provided, circumferentially distributed inside the locking cavity 401. Each locking mechanism 400 includes a locking cavity 401, a locking rod 402, and a locking hole 403. The locking cavity 401 is located inside the insertion plate 202. Multiple locking rods 402 are circumferentially distributed inside the locking cavity 401. One end of the locking rod 402 passes through to the outside of the insertion plate 202 and is inserted into the locking hole 403 provided on the inner wall of the positioning cavity 204. With the locking rod 402 and locking hole 403, the locking rod 402 can be quickly inserted or removed from the locking hole 403, so that the plug plate 202 is fixedly connected to or removed from the drive plate 203. This allows for quick disassembly and replacement of the polishing wheel body 100, which is simple to operate and improves the replacement efficiency of the polishing wheel body 100. Moreover, only the polishing wheel body 100 needs to be replaced.

[0034] like Figure 6As shown, it also includes a pull-out mechanism 500 for disengaging the locking rod 402 from the locking hole 403. The pull-out mechanism 500 includes a handle 501, a pull rod 502, a pull plate 503, and a connecting rod 504. The pull rod 502 is fixedly connected to the handle 501. The other end of the pull rod 502 passes through a slot on the drive plate 203 and is fixedly connected to the pull plate 503. A first return spring 505 is sleeved on the pull rod 502 between the pull plate 503 and the drive plate 203. A connecting rod 504 is hinged to the pull plate 503. The connecting rod 504 corresponding to the locking rod 402 has its other end hinged to the locking rod 402. Through the pull plate 503 and the connecting rod 504, during the upward movement of the pull plate 503 driven by the pull rod 502, all the connecting rods 504 can drive the locking rod 402 to move horizontally, causing the locking rod 402 to disengage from the locking hole 403. Moreover, under the reset action of the first return spring 505, the locking rod 402 can be inserted back into the locking hole 403.

[0035] like Figure 4 , Figure 5 As shown, in some embodiments, a fixed compression groove 205 is provided between the end of the drive plate 203 away from the output shaft 300 and the locking hole 403. The number of fixed compression grooves 205 is the same as that of the locking rod 402. The fixed compression grooves 205 are inclined from the outside to the inside and extend into the positioning cavity 204. Through the fixed compression grooves 205, when the plug plate 202 is inserted into the positioning cavity 204 through the mounting hole 101, the fixed compression grooves 205 compress the locking rod 402, causing the locking rod 402 to retract into the locking cavity 401. After the plug plate 202 is fully inserted into the positioning cavity 204, the position of the locking rod 402 corresponds to the position of the locking hole 403. At this time, under the action of the first return spring 505, the locking rod 402 is inserted into the locking hole 403, completing the fixation of the plug plate 202 by the drive plate 203.

[0036] In some embodiments, a chamfer is provided on the side wall of one end of the locking rod that is movably inserted into the locking hole 403. The chamfer makes it easier for the fixed compression groove 205 to compress the locking rod 402 and also makes it easier for the locking rod 402 to be inserted into the locking hole 403.

[0037] like Figure 6 As shown, an extension tube 206 is slidably sleeved inside the positioning cavity 204 on the outside of the locking rod 402. One end of the extension tube 206 is fixedly connected to the inner wall of the positioning cavity 204. The extension tube 206 can improve the horizontal limiting effect of the plug plate 202 on the locking rod 402, and enable the locking rod 402 to slide more stably on the plug plate 202.

[0038] A positioning rod 506 is movably mounted on the pull plate 503. The other end of the positioning rod 506 is fixedly connected to the drive plate 203. A second return spring 507 is also provided on the positioning rod 506 between the drive plate 203 and the pull plate 503. The positioning rod 506 improves the vertical limiting effect of the pull plate 503, and better enables the pull plate 503 to drive all the connecting rods 504 to move up and down. The second return spring 507 can better cooperate with the first return spring 505, and improve the effect of the locking rod 402 elastically pressing into the locking hole 403.

[0039] A positioning block 508 is fixedly connected to one end of the positioning rod 506 that moves through the pull plate 503. The positioning hole block can limit the distance that the pull plate 503 can move on the positioning rod 506.

[0040] The working principle of this utility model is as follows: When the polishing equipment is working, the drive plate 203 drives the polishing wheel body 100 to rotate at high speed, so that the polishing wheel body 100 polishes the glass. The cooling equipment needs to spray cooling water onto the polishing area. The cooling water entering the cooling chamber 102 is discharged from the cooling chamber 102 along the water outlet 103 and discharged towards the polishing area under the action of centrifugal force during the high-speed polishing process of the polishing wheel body 100, thereby improving the cooling effect and polishing effect.

[0041] When installing the polishing wheel body 100, the drive plate 203 is placed inside the cooling chamber 102, and the plug plate 202 is inserted into the mounting hole 101. The polishing wheel body 100 is dragged towards the drive plate 203. During the process of the plug plate 202 being inserted into the positioning cavity 204, the fixed extrusion groove 205 on the drive plate 203 extrudes the locking rod 402 on the plug plate 202, causing the locking rod 402 to retract into the locking cavity 401. The pull plate 503 drives the pull rod 502 to move upward. During the process, the first return spring 505 and the second return spring 507 are squeezed until the drive plate 203 is in contact with the polishing wheel body 100. At the same time, the plug plate 202 is fully inserted into the positioning cavity 204. At this time, the locking rod 402 and the locking hole 403 are in a corresponding state. Under the reset action of the first return spring 505 and the second return spring 507, the locking rod 402 is quickly inserted into the locking hole 403, completing the fixed connection between the drive plate 203 and the plug plate 202.

[0042] When disassembling the polishing wheel body 100, simply pull the handle 501 to make the pull rod 502 drive the pull plate 503 and all the connecting rods 504 to move upwards simultaneously, causing the locking rod 402 to move horizontally into the locking cavity 401 and retract until the locking rod 402 disengages from the locking hole 403. At this point, the plug plate 202 can be pulled out of the drive plate 203, thus completing the disassembly and assembly of the polishing wheel body 100.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
