Abstract
The utility model relates to a drill way chamfer processing technology field especially relates to a fan mainshaft flange hole chamfering tool, including the boring cutter pole, set up boring cutter head and caudal peduncle on the boring cutter pole, offer a square hole through the wire -electrode cutting on the boring cutter pole, the boring cutter head sets up in the square hole, the front portion of boring cutter head is provided with a cylinder glissile segment that is not less than 50 millimeters long, the cylinder glissile segment with become close clearance sliding fit by the flange hole shape that is cut, the chamfer angle of direction section is 3. The utility model provides an utilize the higher flange hole of size precision as fixing a position the benchmark and then designing the fan mainshaft flange hole chamfering tool who carries out flange hole export chamfer.
Description
Technical field
The utility model relates to orifice chamfer processing technique field, particularly relates to a kind of blower fan main shaft flange hole chamfering tool of chamfer machining.
Background technology
Because machine in recent years adds product, drug on the market, and it is very fierce to compete in limited demand.Each Ji Jia product vendor bringing down prices on the one hand at every possible means, also make an effort in product quality and product appearance on the other hand, strive for staying good impact to user on Product Acceptance Review, finally establish the corporate image that can trust, for the follow-up lasting supply of material lays the first stone.
Blower fan main shaft product is in this processing method all the competitors strive to be the best just, and in the excelsior overall situation of acceptance process, the outward appearance of product and everywhere process details will determine that whether product can enter factory inspection receipts smoothly by user.The main manufacturing procedure of blower fan main shaft product is on lathe and boring machine.Lathe operation can be controlled in strict accordance with drawing by numerical control program, and boring machine operation is then processed by instrument frock.Due to the flange hole quantity of blower fan main shaft more (every part product 50-60 hole needs the aperture of deburring to reach 100-120 after processing), the particularly exit position of flange hole, boring machine cannot carry out chamfering.The on-the-spot magnetic force rig clamping counterbit that adopts carries out chamfering, because each hole machined is all at the same position of counterbit cutting edge, the frequent serious wear of counterbit, cutting resistance is larger, process wastes time and energy, also often there is overlap, gnaw cutter and the uneven quality problems of chamfering angle size, after artificial reconditioning, cause large area reconditioning vestige, had a strong impact on product appearance.
Summary of the invention
The purpose of this utility model is that overcoming above-mentioned deficiency of the prior art provides a kind of flange hole utilizing dimensional accuracy higher as positioning datum and then design the blower fan main shaft flange hole chamfering tool carrying out flange hole outlet chamfering.
The technical solution of the utility model is achieved in that a kind of blower fan main shaft flange hole chamfering tool, and comprise boring cutter bar, described boring cutter bar is arranged cutter head and caudal peduncle, described boring cutter bar offers a square hole by Linear cut, described cutter head is arranged in square hole; The front portion of described cutter head is provided with the cylindrical slid section that is not less than 50 millimeters long, and described cylindrical slid section and the flange hole be cut form small―gap suture and be slidably matched; The end of described cutter head is provided with the guide section that a length of carrying out leading is not less than 20 millimeters.The chamfer angle of described guide section is 3 °.
The good effect that the technical solution of the utility model produces is as follows: boring cutter bar of the present utility model is compared with common boring cutter bar, the front end of cutter head adds the long cylindrical section of one section of 50mm, utilize it to be slidably matched with the small―gap suture of flange hole to position, end has the chamfering of long 3 ° of 20mm to lead.
Boring cutter bar is depressed during use, targeting part on boring cutter bar is extend in flange hole, utilize and make magnetic force rig arrival Working position in the positioning action of 50mm long cylinder, continue pressure boring cutter bar until cutter head cuts at flange hole oral area, reach drawing chamfering and require rear withdrawing.In whole process fast and effectively, there is not the problem of gradation processing.
Due to the detent edge of 50mm long cylinder on boring cutter bar, add self-centering in man-hour and prevent beat, the chamfer surface quality of processing is better, does not have burr and overlap, reaches drawing requirement, follow-uply no longer needs reconditioning to process.The blade of counterbit cannot be changed and sharpening, and loss is serious, and cutter head can be changed and sharpening, has saved a large amount of expenses of buying counterbit.Due to the detent edge of 50mm long cylinder on boring cutter bar, add self-centering in man-hour and prevent beat, the chamfer surface quality of processing is better, does not have burr and overlap, reaches drawing requirement, follow-uply no longer needs reconditioning to process.

Fig. 1 is flange hole chamfering prop structure schematic diagram of the present utility model.
Fig. 2 is one of structural representation of the utility model boring cutter bar.
Fig. 3 is the structural representation two of the utility model boring cutter bar.
Be labeled as in figure: 1, cutter head; 2, caudal peduncle; 3, cylindrical slid section; 4, guide section; 5, square hole.
Detailed description of the invention
A kind of blower fan main shaft flange hole chamfering tool, as shown in Figure 1, 2, 3, comprise boring cutter bar, described boring cutter bar is arranged cutter head 1 and caudal peduncle 2, described boring cutter bar offers a square hole 5 by Linear cut, and described cutter head is arranged in square hole; The front portion of described cutter head is provided with the cylindrical slid section 3 that is not less than 50 millimeters long, and described cylindrical slid section and the flange hole be cut form small―gap suture and be slidably matched; The end of described cutter head is provided with the guide section 4 that a length of carrying out leading is not less than 20 millimeters.The chamfer angle of described guide section is 3 °.
By blower fan main shaft vertical display, add and first load onto cutter head at boring cutter bar man-hour, compress after adjusting cutter head position, then boring cutter bar is contained on magnetic force rig.During use, magnetic force rig magnetic force is not opened, and can freely promote in plane, pressure boring cutter bar, targeting part on boring cutter bar is extend in flange hole, all depresses gradually, under the positioning action of 50mm long cylinder, magnetic force rig arrives Working position, opens magnetic force and fixes.Continue pressure boring cutter bar until cutter head cuts at flange hole oral area, reach drawing chamfering and require rear withdrawing.All exit rear shutdown, check processing effect.
