The positioning column 2 is connected with the output end of the motor 4 and is rotatably fixed on the substrate 1, and the motor 4 can drive the positioning column 2 to rotate.
The chamfer subassembly includes fixed connection in base plate 1 bottom and with the concentric fixed cover 5 of reference column 2, the activity cup joints the swivel sleeve 6 on fixed cover 5, support arm 7 that fixed connection can stretch out and draw back on swivel sleeve 6 and set up the stop collar 8 of keeping away from swivel sleeve 6 tip at support arm 7, can see out from figure 4, fixed cover 5 cover is on reference column 2 but not with reference column 2 contact, can not receive the influence of fixed cover 5 when consequently reference column 2 rotates. The support arm 7 may be two bars that can be nested, and the relative positions of the two bars may be fixed by bolts, thereby fixing the length of the support arm 7. Therefore, the chamfering device can be used for chamfering circular-arc heat dissipation hole holes with different radiuses to a certain extent.
As can be seen from FIG. 4, the upright rod 9 is movably inserted in the position-limiting sleeve 8, the bottom of the upright rod 9 is provided with a polishing mechanism, the polishing mechanism comprises a rotatable polishing head 10, the polishing head 10 comprises a polishing wheel 27 for chamfering the heat-radiating holes and a position-limiting post 28 capable of being inserted into the heat-radiating holes, a position-limiting table 11 is fixedly arranged on the upright rod 9 between the polishing head 10 and the position-limiting sleeve 8, a spring 12 is sleeved on the upright rod 9 between the position-limiting table 11 and the position-limiting sleeve 8, a lifting mechanism is arranged on the fixed sleeve 5, the lifting mechanism comprises a second rotating sleeve 13 movably sleeved on the fixed sleeve 5, a guide rod 14 arranged on the position-limiting sleeve 8 and a sliding sleeve 15 slidably sleeved on the guide rod 14, a connecting rod 16 is hinged between the sliding sleeve 15 and the position-limiting table 11, the second rotating sleeve 13 is provided with a shifting rod 17 matched with the sliding sleeve 15, when the sanding head 10 abuts against the ends of the louvers, the lifting mechanism is able to compress the spring 12 and lift the sanding head 10.
Specifically, when the polishing head 10 collides with the edge of the heat dissipation hole, since the limiting column 28 of the polishing head 10 is blocked by the housing, the shift lever 17 continues to shift the sliding sleeve 15 under the rotation action of the second rotating sleeve 13, so that the sliding sleeve 15 moves on the guide rod 14, and at this time, since the limiting column 28 is inactive, the sliding sleeve 15 can pull the limiting table 11 upwards through the connecting rod 16, so that the limiting table 11 moves upwards relative to the limiting sleeve 8, thereby realizing the lifting of the polishing head 10. After the polishing head 10 is lifted, the polishing head can enter the next section of arc-shaped heat dissipation hole, and the polishing and trimming work is continued.
In order to further ensure the trimming effect, it can be seen from fig. 4 and 5 that the guide rods 14 are symmetrically arranged on both sides of the stop collar 8, and correspondingly, the connecting rod 16 and the sliding sleeve 15 are also symmetrically arranged.

As can be seen from fig. 3 and 4, when the motor 4 works, the positioning column 2 can be driven to rotate, and then the polishing head 10 is rotated through the meshing relationship between the five gear 25 and the six gear 26, so that the polishing head 10 can polish the edges of the heat dissipation holes. When the distance between the polishing heads 10 needs to be adjusted, the size of the gear six 26 needs to be changed together, so that the gear six 26 on two adjacent polishing heads 10 can keep a meshing relationship.
When in use: the distance between the polishing heads 10 and the length of the supporting arm 7 are adjusted in advance, so that the invention can match the specification of the upper radiating holes. The positioning column 2 is aligned to the circle center of the arc-shaped heat dissipation hole, the relative position of the polishing head and the shell is fixed by using the suction disc 29, each polishing head 10 is inserted into the heat dissipation hole at the moment, after the motor 4 is started, the gear five 25 drives the gear six 26 to enable the polishing head 10 to polish the heat dissipation hole, the shift lever 17 rotates to continuously change the position of the polishing head 10, and the polishing head 10 can move along the shape of the arc-shaped heat dissipation hole, so that the high-efficiency polishing of the arc-shaped heat dissipation hole is realized, the labor is saved, other parts of the shell cannot be scraped, and the surface of the shell is kept smooth.
