Description

Technical Field

[0001] The utility model relates to the technical field of crystal grinding, in particular to a high-efficiency grinding device for crystal hot diamonds. Background Art

[0002] Hot-drilling technology is a processing technology that can set diamonds on leather, cloth and other materials. Hot-drilling machines are usually used in the hot-drilling process. The working principle is to use high temperature (most diamonds are crystal or glass and are not afraid of high temperatures), the common temperature is around 150-200, to melt the glue layer at the bottom of the diamond, so that it can be attached to the object.

[0003] At present, a flat grinder is generally used for polishing crystal. The existing flat grinder includes a frame, a motor is arranged on the frame, and a grinding disc for grinding is installed on the rotating shaft of the motor. Then the operator adheres the crystal to the end of a hand-held rod, and then holds the hand-held rod by hand to bring the crystal into contact with the grinding disc for grinding. In order to make the crystal more transparent, grinding discs of different purposes are used to grind the crystal one by one, which requires continuous replacement of the grinding disc. However, the grinding disc and the rotating shaft of the motor are currently threadedly fixed by nuts. Tools are required for disassembly and installation when disassembling and assembling the grinding disc, which is inefficient. Utility Model Content

[0032] The disassembly and assembly mechanism 5 includes an upper connecting sleeve 501, a lower connecting sleeve 502 and a first spring 503. The cross section of the upper connecting sleeve 501 is T-shaped. The bottom outer wall of the lower connecting sleeve 502 is fixedly connected with an annular pressing plate 5021. The lower end of the upper connecting sleeve 501 is slidably sleeved inside the first spring 503. Both the upper connecting sleeve 501 and the lower connecting sleeve 502 can be slidably sleeved on the rotating rod 4. The first spring 503 is sleeved on the lower end of the upper connecting sleeve 501. The upper end of the first spring 503 is against the upper bottom of the lower connecting sleeve 502. The lower end of the spring 503 is pressed on the top of the annular pressure plate 5021. In order to prevent the upper connecting sleeve 501 from separating from the lower connecting sleeve 502, a limiting slide groove 5022 is provided on the inner wall of the lower connecting sleeve 502. The lower end outer wall of the upper connecting sleeve 501 is fixedly connected with a slider 5011, and the slider 5011 is slidably set in the limiting slide groove 5022. By pressing the upper connecting sleeve 501 downward, the annular pressure plate 5021 can be pressed tightly against the top of the grinding disc 6. The upper connecting sleeve 501 is provided with a locking component that can fix the upper connecting sleeve 501 on the rotating rod 4.

[0033] Specifically, the locking assembly includes a clamping head 504, and a plurality of clamping grooves 401 are equidistantly provided on the upper end of the rotating rod 4 from top to bottom. An assembly groove 5012 is provided on the inner wall of the upper connecting sleeve 501. The clamping head 504 is slidably arranged in the assembly groove 5012. One end of the clamping head 504 is fixedly connected to a pull rod 505, and one end of the pull rod 505 slides through the upper connecting sleeve 501 and is fixedly connected to a stopper 507. A second spring 506 is sleeved on the pull rod 505, and one end of the second spring 506 abuts against one side of the clamping head 504, and the other end of the second spring 506 abuts against one end of the assembly groove 5012. The clamping head 504 can be clamped into the clamping groove 401. In order to facilitate smoother pressing down of the upper connecting sleeve 501, a chamfer is provided at the bottom of one end of the clamping head 504 close to the clamping groove 401.

[0034] By adopting the above technical solution, when installing the grinding disc 6, the grinding disc 6 is first sleeved on the rotating rod 4 so that the bottom of the grinding disc 6 is pressed on the supporting sleeve 11, and then the upper connecting sleeve 501 and the lower connecting sleeve 502 are sleeved on the rotating rod 4, and then the upper connecting sleeve 501 is pressed downward so that the first spring 503 continuously applies pressure to the annular pressure plate 5021, and the grinding disc 6 is firmly fixed between the annular pressure plate 5021 and the supporting sleeve 11. During the downward movement of the upper connecting sleeve 501, the clamping head 504 continuously moves downward. Due to the chamfer set on the clamping head 504, the clamping head 504 moves downward. When the upper connecting sleeve 501 is moved, there will be no resistance. When the upper connecting sleeve 501 is pressed downward into place, the clamping head 504 is inserted into the corresponding clamping groove 401 under the elastic force of the second spring 506, and the installation of the grinding disc 6 is completed. When removing the grinding disc 6, it is only necessary to pull the stopper 507 away from the rotating rod 4 so that the clamping head 504 is pulled out of the clamping groove 401. At this time, the limit on the upper connecting sleeve 501 is released, and the upper connecting sleeve 501 is pushed upward under the elastic force of the first spring 503, thereby releasing the pressure applied to the grinding disc 6, and then the entire disassembly and assembly mechanism 5 is pulled out from the rotating rod 4 to complete the disassembly of the grinding disc 6.

[0035] Specifically, in order to increase the friction between the annular pressing plate 5021 and the grinding disc 6 , an anti-slip pattern is provided on the bottom of the annular pressing plate 5021 .

[0036] Specifically, in the present embodiment, a water storage area 204 is formed between the outer wall of the protrusion 202 and the inner wall of the mounting groove body 2, a water pump 8 is fixedly installed at the bottom of the frame 1, the water inlet of the water pump 8 is connected to the bottom of the water storage area 204, the water outlet of the water pump 8 is connected to a bamboo tube 9, the water outlet of the bamboo tube 9 faces the grinding disc 6, and the arranged water pump 8 and bamboo tube 9 can spray water toward the grinding disc 6 during the grinding of the crystal, thereby effectively avoiding the phenomenon of dust flying around during grinding, and the processing operation is more environmentally friendly.

[0037] Specifically, the top of the grinding disc 6 is lower than the top of the mounting tank 2. This arrangement prevents water sprayed onto the grinding disc 6 from splashing to the outside due to the centrifugal force of the rotation of the grinding disc 6.

[0038] Specifically, the inner wall of the installation tank 2 is fixedly connected with an annular retaining bar 201, an annular water filter plate 3 is arranged on the annular retaining bar 201, and a non-woven filter layer is laid on the annular water filter plate 3.
