During operation, connecting pipe 44 is connected with the coolant liquid equipment, when driving motor 302 and positive reverse motor 35 start, the coolant liquid equipment carries the coolant liquid to connecting pipe 44, the coolant liquid passes through connecting pipe 44, liquid reserve tank 47, hydrojet hole 43 sprays on a section of thick bamboo 37 and the drill bit raw and other materials of polishing, thereby make a section of thick bamboo 37 of polishing carry out the in-process of top polishing to the drill bit raw and other materials and obtain cooling, the problem that the abrasive machining effect is not good because of the temperature reason causes among the process of having avoided the top of drill bit raw and other materials to polish, drive liquid reserve tank 47 through L shape support 45 when T shape seat 33 removes, make liquid reserve tank 47 be located the top of a section of thick bamboo 37 of polishing all the time.

Referring to fig. 4, the front lower end face and the rear lower end face of the liquid storage tank 47 are provided with the liquid blocking plates 46, the front liquid blocking plates 46 and the rear liquid blocking plates 46 are respectively positioned on the front side of the polishing cylinder 37 and the rear side of the rotating shaft 301, when the polishing machine works and coolant is sprayed on the polishing cylinder 37 and the drill bit raw material, the coolant is easily thrown out due to the rotation of the polishing cylinder 37, and the liquid blocking plates 46 block the thrown coolant, so that the problem that the coolant splashes around is avoided.

Refer to fig. 4, 1 lower terminal surface of processing platform set up bilateral symmetry and arrange and run through the T-slot 10 of preceding terminal surface, sliding connection has T shaped plate 11 in the T-slot 10, two T shaped plate 11 lower terminal surfaces about through installing screening box 12 jointly, the below of screening box 12 is provided with reservoir 13, the piece that polishes on with the drill bit raw and other materials when the coolant liquid cools down the drill bit raw and other materials dashes down, piece and coolant liquid fall to screening box 12 from falling bits groove 30 on, screening box 12 sieves the collection to the piece in the coolant liquid, and the coolant liquid is from screening box 12 to in the reservoir 13 of whereabouts, so that the coolant liquid recycling after filtering.

During specific work, first step, place the drill bit raw and other materials on board 21 is placed to the arc, then adjust the distance between drill bit raw and other materials both ends and the section of thick bamboo 37 of polishing for the both ends of drill bit raw and other materials and two distances between the section of thick bamboo 37 of polishing equal, then drive No. two-way threaded rod 25 through adjusting pole 26 and rotate, two arc cardboard 23 remove to drill bit raw and other materials around No. two-way threaded rod 25 rotates and drives, until arc cardboard 23 with the chucking of drill bit raw and other materials.

Secondly, the forward and reverse rotation motor 35 and the driving motor 302 are simultaneously started, the driving motor 302 drives the driving ring 303 which is slidably connected through the fixture block 307 to rotate through the rotating shaft 301, the driving ring 303 rotates to drive the grinding cylinder 37 to rotate through the meshing transmission between the rotating gears 305, meanwhile, a forward and reverse rotation motor 35 drives the left T-shaped seat 33 and the right T-shaped seat 33 to move towards the drill bit raw material through a first bidirectional threaded rod 34, thereby realizing the function of moving and feeding the raw material of the drill bit while the grinding cylinder 37 rotates for grinding, the rotating shaft 301 and the driving ring 303 slide through the clamping between the clamping groove 306 and the clamping block 307, so that when the rotating shaft 301 drives the driving ring 303 to rotate, the T-shaped seat 33 can drive the driving ring 303 to move through the connecting plate 304, therefore, the gear on the driving ring 303 is always meshed with the gear on the grinding cylinder 37, so that the grinding cylinder 37 can simultaneously process the centers of the left end and the right end of the drill bit raw material.

And thirdly, when the driving motor 302 and the forward and reverse rotating motor 35 are started, the cooling liquid equipment conveys cooling liquid to the connecting pipe 44, and the cooling liquid is sprayed on the grinding cylinder 37 and the drill bit raw material through the connecting pipe 44, the liquid storage tank 47 and the liquid spraying hole 43, so that the grinding cylinder 37 is cooled in the process of grinding the tip of the drill bit raw material.

Fourthly, the piece that polishes on the drill bit raw and other materials dashes down when the coolant liquid cools down the drill bit raw and other materials, and piece and coolant liquid fall to screening box 12 from falling bits groove 30 on, and screening box 12 screens the piece in the coolant liquid and collects, and the coolant liquid from screening box 12 to falling to the hold up tank 13 in to the coolant liquid circulation after the filtration uses.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
