Description
Technical field
The utility model belongs to blower part processing equipment field, and in particular to a kind of air blower is drilled with shaft coupling to be covered
Mould.
Background technology
In conventional fan composition, one shares two groups of shaft couplings, and one group is motor side shaft coupling, and another group is spindle end connection
Axle device.Motor side shaft coupling needs to coordinate motor shaft head, and conventional motor shaft head diameter has Φ 38, Φ 42, Φ 48, Φ 55, Φ
90th, Φ 65, Φ 75, Φ 80 etc., the major axis diameter that spindle end shaft coupling coordinates have Φ 65, Φ 80, Φ 100, Φ 125 etc..This two
In group shaft coupling manufacturing process, boring requirement precision is higher.At present, drilling is the fairly common manufacturing procedure of machining industry,
Universal processing request is less high, it is allowed to certain error be present, equipment precision used is also poor, and generally use is manually surveyed
Amount line, it is determined that the drilling center of circle, recycles drill bit to be processed.But the shaft coupling in air blower uses in pairs, utilization is above-mentioned
Method can only carry out pairing processing, it is ensured that drilling axiality, it is difficult to realize prior single-piece work, after causing sometimes on the duration very by
It is dynamic.And above method borehole accuracy is low, it is difficult to realizes the interchangeability between identical shaft coupling, processing efficiency is not also high.Certainly
, using associated machine tool, even numerical control drilling machine carries out drilling machining, very high during borehole accuracy, but cost of investment
Also it is very big.
Utility model content
To solve the problems, such as that above technology is present, the utility model provides a kind of air blower shaft coupling drilling cover die, energy
Meet that a variety of internal diameters of shaft coupling are fixed, realize that precise positioning drills, meet the interchangeability between shaft coupling, realize single-piece shaft coupling
Produce in advance.
Its technical scheme is：
A kind of air blower shaft coupling drilling cover die, including workbench, clamping screw, shaft coupling, mould, diameter of axle step,
Pressing plate, nut and drill bit, fixed vertical is provided with clamping screw on the workbench, and the shaft coupling is placed through clamping screw
On the table, mould is provided with above the shaft coupling, middle part is fixedly installed one-level above diameter of axle step, institute below mould
State diameter of axle step to be stuck on shaft coupling endoporus, be provided with pressing plate above the mould, the clamping screw upper end sequentially passes through axle
Coordinate in the middle part of footpath step, mould and pressing plate with nut thread, alignment hole is provided with the mould, brill is provided with above alignment hole
Head.
Further, it is provided with wear-resistant sleeve in the alignment hole on the mould.
When shaft coupling drills, shaft coupling is positioned on Drilling machines bench, centre passes through hold-down bolt, then mould is placed
On shaft coupling.If drilling machining is carried out to motor side shaft coupling, motor side shaft coupling hole drilling die is selected, under mould
The diameter of axle step of side is provided with Φ 38, Φ 42, Φ 48, Φ 55, Φ 90, Φ 65, Φ 75,80 multistage specifications of Φ, meets in various
The motor side shaft coupling drilling in footpath.If drilling machining is carried out to spindle end shaft coupling, the drilling of spindle end shaft coupling is selected
Mould, the diameter of axle step below mould are provided with Φ 65, Φ 80, Φ 100,125 multistage specifications of Φ, meet the main shaft of various internal diameters
Hold shaft coupling drilling.Replaceable wear-resistant sleeve is provided with alignment hole on mould, can directly change, increase after wear-resistant sleeve abrasion
Mould service precision and life-span.Pressing plate is promoted followed by nut, shaft coupling and mould are fixed on the table, control drill bit
Wear-resistant sleeve is directed at, carries out vertical drilling, completes drilling machining.Due to being provided with diameter of axle step, deposited between mould and shaft coupling
In gap, processing chip removal is most of to discharge from the gap, is unlikely to heavy wear mould hole, causes error excessive.
The beneficial effects of the utility model：
The utility model is simple in construction, manufacturing cost is low, can meet that a variety of internal diameters of shaft coupling are fixed, and realizes that precise positioning bores
Hole, meet the interchangeability between shaft coupling, realize that single-piece shaft coupling produces in advance；Sharpening equal error of ruling, drill is avoided simultaneously,
Improve borehole accuracy and efficiency.
