In addition, because the space inside the grinding head 9 is very limited, the distance that the limiting sleeve 29 drives the guide block 32 to slide outwards along the horizontal direction when the inside of the grinding head 9 slides upwards is very limited, so the invention chooses to adopt the cooperation of the structures such as the sliding column 34, the gear 38 and the rack 39, and the like, the movable contact 35 is arranged on the sliding column 34, the travel of the sliding column 34 can be prolonged by the movement of the guide block 32 through the cooperation of the gear 38 and the rack 39, so that people can select travel switches with more types (the distance between the movable contact 35 and the fixed contact 31 is increased, the types of the travel switches can be relatively increased), and after adopting the structure, the travel switch is arranged outside the grinding head 9 (the movable contact 35 can also extend outside the grinding head 9 when moving, thereby being convenient for the subsequent maintenance and replacement of the travel switch by people).
When the polishing head 9 finishes polishing the polishing piece a, the first motor 13 is started again to drive the polishing head 9 to move upwards, and when the contact piece 45 and the upper end face of the polishing piece a are out of contact, the first spring 37 stretches to drive the guide block 32 to return to the initial position due to the reaction force, and the contact piece 45 returns to the initial position under the action of the guide block 32 and gravity.
In the process of polishing the polishing piece a by the polishing head 9, a large amount of heat is generated by friction of the polishing piece a and a large amount of dust is generated, in order to avoid dust lifting, the lower end surface of the polishing head 9 cannot be timely emitted out due to the large amount of heat to cause hot corrosion, a water pipe 26 is sleeved at the axis of the polishing head 9 in a sliding manner, the bottom of the water pipe 26 is fixedly connected with the center of the limiting plate 44, and the top of the water pipe is communicated with the water tank 8 at the top of the lifting plate 14 after penetrating through the first connecting column 25, the driven wheel 17 and the lifting plate 14 in sequence. The contact 45 drives the water pipe 26 to synchronously move in the moving process, the inside of the polishing head 9 is positioned above the two rectangular groove bodies 28 to form a circular ring groove 41, the circular ring groove 41 and the polishing head 9 are concentrically arranged, a water supply runner 42 communicated with the circular ring groove 41 is further arranged in the polishing head 9, the water supply runner 42 is formed by three parts of a horizontal segment, an inclined segment and a vertical segment, wherein the horizontal segment is distributed along the radial direction of the polishing head 9 and is communicated with the inside of the circular ring groove 41, the inclined segment and the vertical segment are provided with four groups in total, the top of the inclined segment in each group is connected with the horizontal segment, the bottom of the inclined segment is connected with the vertical segment, the vertical segment is communicated with the outside of the polishing head 9, and the four vertical segments are distributed in parallel along the radial direction of the polishing head 9. The middle part of water pipe 26 is formed with second intercommunication mouth 43, when contact 45 retract to the storage tank 50 inside, second intercommunication mouth 43 just can communicate with circular ring groove 41, and the top of water pipe 26 just extends to the bottom of water tank 8, the check valve 27 is installed to the position department of water tank 8's bottom corresponding to water pipe 26, when contact 45 retract to the storage tank 50 inside, water pipe 26 can jack-up check valve 27 and stretch into water tank 8 inside, water inside water tank 8 just like this can be followed water pipe 26, second intercommunication mouth 43 gets into circular ring groove 41 inside, and finally flow into between polishing head 9 and the polishing piece a through water supply runner 42, the heat in this region can not only be taken away to the outflow water, and can also wet the powder of polishing, avoid the dust of lifting.

In the long-term actual polishing operation, if the contact 45 is just extended into the accommodating groove 50, the bottom of the contact 45 will contact with the polishing piece a, if polishing is performed for a long time, the bottom of the contact 45 will generate loss, the most direct result of the loss is that the height of the contact 45 is reduced, when the contact is retracted into the accommodating groove 50, the distance for driving the limiting sleeve 29 to move upwards is shortened, the moving distance of the guide block 32 in the horizontal direction is reduced, and finally the stationary contact 31 and the movable contact 35 cannot be touched, so that the automatic stop of the first motor 13 cannot be realized, and the polishing thickness cannot be controlled. Therefore, it is preferable that the contact 45 does not participate in polishing all the time, and only the annular region at the bottom of the polishing head 9 is used for polishing, so that the service life of the whole polishing device can be ensured to the greatest extent. In view of this, the height of the accommodating groove 50 is greater than that of the contact 45, the sliding block 49 is fixed on the groove wall of the sliding groove 48 of the limiting pipe sleeve, the vertical limiting sliding groove 52 is arranged on the inner wall of the limiting pipe sleeve 29 at the position corresponding to the sliding block 49 along the vertical direction, the height of the vertical limiting sliding groove 52 is exactly the same as that of the contact 45, the inner wall of the limiting pipe sleeve 29 is provided with the spiral groove 53 downwards from the bottom of the vertical limiting sliding groove 52, and the spiral groove 53 is communicated with the annular groove 54 arranged on the inner wall of the limiting pipe sleeve 29 after one circle of spiral. When the contact 45 just retracts into the accommodating groove 50, the sliding block 49 just slides from the top to the bottom relative to the vertical limiting sliding groove 52, then the sliding block 49 is opened to slide into the spiral groove 53 along with the rotation of the polishing head 9, the water pipe 26 is driven to slide upwards under the limiting action of the spiral groove 53, after the sliding block 49 slides into the annular groove 54, the water pipe 26 does not slide upwards any more, and at the moment, the bottom of the contact 45 and the polishing piece a are completely separated. Since the limit sleeve 29 and the water pipe 26 continue to slide upwards for a certain distance, the top of the limit sleeve 29 eventually exceeds the top of the guide block 32, which causes the guide block 32 to be blocked and unable to realize resetting, the invention also sets a baffle 46 outside the water pipe 26, the inner side of the baffle 46 is slidingly connected with the water pipe 26, the outer side is rotationally connected with the polishing head 9 and forms a limit structure with the polishing head in the vertical direction, when the polishing head 9 rotates, the baffle 46 keeps still, a second spring 47 is arranged between the baffle 46 and the limit plate 44, and the second spring 47 is sleeved outside the water pipe 26. After finishing polishing, the person can directly rotate the polishing head 9 manually in the opposite direction, the second spring 47 is in a compressed state, and when the sliding block 49 slides to the opening at the bottom of the spiral groove 53 along the annular groove 54, the sliding block 49 slides into the spiral groove 53 under the elastic force of the second spring 47, and finally drives the contact element 45 to reset completely, so that the resetting of the guide block 32 is not affected. In addition, the distance that the contact 45 continues to move upward after being retracted into the accommodating groove 50 is also small, and the communication between the second communication port 43 and the annular groove 41 is not affected.
Finally, it should be noted that the shape of the pressing block 55 is controlled in the invention, and the heights of the transverse rod 30 and the stationary contact 31 outside the polishing head 9 ensure that the transverse rod 30 and the stationary contact 31 do not interfere with the pressing block 55 when the polishing head 9 polishes near the center of the polishing piece a.
