Technical Field

[0001] The utility model relates to the technical field of water drill grinding and polishing machines, in particular to a dividing head of a water drill grinding and polishing machine. Background Art

[0002] The water drill grinding and polishing machine is a device used for grinding and polishing water drill blanks. Its working principle is to transport the water drill blanks to the grinding and polishing station through the water drill fixture, and then control the rotation of the grinding and polishing wheel to grind and polish the water drill blanks.

[0003] According to a disclosed water drill grinding and polishing machine and water drill surface changing device (publication number: CN220718833U), in the above application, the servo motor drive method adopted is simple to control, fast to execute and accurate in positioning; further, a rocker arm assembly linkage method is adopted, which has lower energy consumption.

[0004] However, in actual use of the above equipment, the grinding and polishing head used for polishing will generate a large amount of heat during the high-speed rotation process, and the efficiency of cooling this heat is limited even through external water spraying, which limits the efficiency of the continuous working time of the device and reduces the use effect of the device; in view of this, we propose a dividing head for a water drill grinding and polishing machine.

[0011] Preferably, the protrusion is arranged inside the transmission cavity, and the number of the arc blocks is arranged in several groups, and the several groups of arc blocks are evenly distributed on the inner surface of the transmission cavity in a circular array, so that the protrusion intermittently contacts the arc block, thereby prompting the round rod arranged inside the transmission rod to move in the horizontal direction toward the center of the grinding and polishing head.

[0012] Preferably, the heat dissipation cavity and the guide cavity are filled with heat transfer oil so that the area near the curved outer surface of the grinding and polishing head is filled with heat transfer oil, and the guide cavity extends to the heat dissipation tube so that the heat of the heat transfer oil can be exchanged with the heat dissipation tube.

[0013] Preferably, the outer surface of one end of the round rod near the center of the grinding and polishing head is set to a spherical surface, and the transmission plate is provided with an arc plate on a section of the arc-shaped outer surface near the center of the grinding and polishing head, so that when the round rod is periodically inserted into the center of the grinding and polishing head, its spherical surface will intermittently squeeze the arc plate, so that the transmission plate intermittently drives the arc-shaped top block to squeeze the silicone sleeve.

The grinding and polishing head and the heat dissipation cylinder rotate relatively. The convex block intermittently squeezes the arc block to prompt the round rod to be intermittently inserted into the interior of the grinding and polishing head in the horizontal direction, and then cooperates with the transmission plate and the connecting spring to make the arc top block intermittently squeeze the silicone sleeve into the heat dissipation cavity to prompt the heat transfer oil filled in the heat dissipation cavity and the guide cavity to generate a waveform push, thereby prompting the heat transfer oil to produce a flow effect, so that the heat transfer oil can timely dissipate the heat generated by the grinding and polishing head during operation, thereby ensuring the operation effect of the grinding and polishing head.

[0018] 2. The dividing head of the water drill grinding and polishing machine is provided with a spoiler component. During the high-speed rotation of the grinding and polishing head, the arc-shaped top block periodically squeezes the silicone sleeve to cause the heat transfer oil in the heat dissipation cavity to flow. The flowing heat transfer oil will promote the rotation of the rotating ring in the horizontal direction, and the rotating grinding and polishing head will also drive the rotating ring to rotate in an almost disorderly manner, thereby affecting the flow direction of the heat transfer oil, improving the heat driving effect of the heat transfer oil on the grinding and polishing head, and then ensuring the continuous working effect of the grinding and polishing head.

Specifically, an annular contact portion is provided on the outer surface of the grinding and polishing head 9 close to the protective cover 4, and the annular contact portion is adapted to the end of the heat dissipation cylinder 101, so that a part of the end of the heat dissipation cylinder 101 extends into the inner of the grinding and polishing head 9.

At this time, the transmission rod 8 and the heat dissipation cylinder 101 rotate relative to each other, so that the convex block 106 intermittently contacts the arc block 104, thereby prompting the round rod 105 arranged inside the transmission rod 8 to move toward the center of the grinding and polishing head 9 in the horizontal direction, and then make reciprocating motion in the horizontal direction under the elastic force of the reset spring 107.
