As shown in fig. 1 to 5, the present invention provides an automatic waxing mechanism, which is used in cooperation with a polishing and grinding device to coat wax 16 on a polishing wheel of the polishing and grinding device, and includes a flexible movable part 100, a fixed supporting part 200 and a power driving part 300, wherein the power driving part 300 is used to drive the flexible movable part 100 to make a linear flexible motion on the fixed supporting part 200, and the wax 16 is driven by the flexible movable part 100 to make a linear reciprocating motion, so as to realize the feeding and returning actions of the wax 16, wherein:

the telescopic movable part 100 comprises an optical axis 2 and a wax containing support 13, wherein two ends of the optical axis 2 are respectively provided with an optical axis fixing seat 1, the wax containing support 13 is connected with the optical axis fixing seat 1 at one end, the front end of the wax containing support 13 is provided with a fixed shaft 14 in a cantilever structure, the fixed shaft 14 is provided with a sleeve 18 through a one-way bearing 17, the sleeve 18 is used for mounting wax materials 16, the wax materials 16 rotate along the sleeve 18 in a one-way mode relative to the fixed shaft 14, and the end face, close to the support plate, of the sleeve 18 is coaxially;

the fixed support part 200 comprises a fixed block 4 and a pawl 11 connected with the fixed block 4, the fixed block 4 is provided with a sliding sleeve 3 sleeved with the optical axis 2, and when the optical axis 2 slides to one end along the sliding sleeve 3, the optical axis 2 drives the wax material 16 on the sleeve 18 to extend forwards; when the optical axis 2 slides to the other end along the sliding sleeve 3, the wax material 16 on the sleeve 18 is driven to retract backwards; when the wax material 16 retracts to the right position, the wax loading support 13 is close to the fixed block 4, the pawl 11 is pushed to contact with the teeth of the ratchet wheel 15 and pushes the ratchet wheel 15 to rotate by a preset angle, so that the sleeve 18 and the wax material 16 are driven to synchronously rotate, the preset angle is 360 degrees divided by the number of teeth of the ratchet wheel 15, and the rotation direction of the ratchet wheel 15 is consistent with the unidirectional rotation direction of the unidirectional bearing 17.

The automatic waxing mechanism of the invention is used for matching with the polishing equipment, and the wax material 16 on the telescopic movable part 100 moves forwards and backwards in a straight line to feed and return; the flexible movable part 100 drives the wax material 16 to extend forwards to a proper position, and then the wax material is contacted with a polishing wheel of polishing equipment, and the rotating polishing wheel rubs against the wax material 16, so that the wax can be coated on the polishing wheel; the wax 16 is required to be returned after contacting the rotating polishing wheel for a short time, otherwise, the wax is coated too much, which causes waste, and at this time, the flexible movable part 100 drives the wax 16 to return to the position and wait for the next feeding.

In the in-service use process, because one-way bearing 17 has restricted the rotation direction of sleeve 18, and wax material 16 and sleeve 18 are fixed mounting for under one-way bearing 17's effect, when making wax material 16 and rotatory throwing aureola contact, the throwing aureola can not drive wax material 16 rotatory, and then has improved the frictional force between wax material 16 and the throwing aureola, makes the coating that wax material 16 can be better on the throwing aureola.

The one-way intermittent motion mechanism consists of the ratchet wheel 15 and the pawl 11, the pawl 11 pushes the ratchet wheel 15 to move in a stepping mode, namely, the telescopic movable part 100 retracts to the right position each time, the pawl 11 pushes the ratchet wheel 15 to rotate once, the rotating angle is 360 degrees divided by the number of teeth of the ratchet wheel 15, and therefore the wax 16 extending out at each time rotates by a certain angle, the polishing wheel can be different from the contact part of the wax 16 at each time, and further the wax 16 is uniformly consumed.
