Description
Technical field
The utility model is related to air conditioner parts field, more particularly to a kind of through-flow fan blade disk for being applicable automatic welding machine.
Background technology
Through-flow fan blade is a kind of air-conditioning internal machine fan blade, and it includes motor reel, steel shaft disk, and in motor reel and steel
Disk is saved in several between reel to constitute.By artificial between the motor reel of traditional through-flow fan blade, middle section disk and steel shaft disk
The mode of welding is attached, but is used with the development of automatic welding machine, and through-flow fan blade is also progressively replaced using machinery welding
Human weld, but be due to that positioning hole 13 and centre hole 14 can be provided with above-mentioned disk body 11, and the positioning of Traditional Man identification
Hole is cylinder, and relative accuracy is relatively low, and what the automatic welding machine as shown in Fig. 1 ~ Fig. 2 was utilized is the principle searching positioning of two-dimensional projection
Hole, therefore the positioning hole in figure or centre hole are cannot be distinguished from, it is badly in need of being improved.
The content of the invention
In order to solve the above problems, the purpose of this utility model is to provide a kind of through-flow fan blade disk, the through-flow fan blade disk
Optimization is improved to the pass of positioning hole, so as to lift positioning precision, automatic welding machine operation is applicable.
In order to realize above-mentioned purpose, the utility model employs following technical scheme：
It is provided with a kind of through-flow fan blade disk for being applicable automatic welding machine, including disk body, the axial end of the disk body many
Individual blade docking groove, multiple blade docking grooves are along same periphery rule setting on the outer end of axial end；Its feature exists
In：Centre hole and positioning hole, the blind hole that centre hole and positioning hole are axially opened up along disk body are additionally provided with the periphery；It is described fixed
Position hole is in truncated cone-shaped, and the aperture end face and bottom hole end face of positioning hole are the concentric circles centered on axis.
Preferably, the section of the blade docking groove is in circular arc, the groove bottom of blade docking groove is provided with blade pair
Connect muscle.
It is provided with a kind of through-flow fan blade disk for being applicable automatic welding machine, including disk body, the axial end of the disk body many
Individual blade docking groove, multiple blade docking grooves are along same periphery rule setting on the outer end of axial end；Its feature exists
In：Centre hole and positioning hole, the blind hole that centre hole and positioning hole are axially opened up along disk body are additionally provided with the periphery；It is described fixed
Position hole is on same axis in cone, the aperture end face center of circle and the bottom hole end points of positioning hole.
Preferably, the section of the blade docking groove is in circular arc, the groove bottom of blade docking groove is provided with blade pair
Connect muscle.
The utility model uses above-mentioned technical proposal, and the technical scheme is related to a kind of through-flow fan blade disk, the through-flow fan blade disk
On positioning hole be set to truncated cone-shaped or cone, so as to lift positioning precision, be applicable automatic welding machine operation.Specifically have following
Both sides advantage：1st, the figure of a concentric circles is formed in the state of two-dimensional projection, distinguishes, is easy to the circle of centre hole
Automatic welding machine is recognized；2nd, the section of round platform or circular cone forms a larger reflective surface, can increase positioning precision.Make product
Production efficiency greatly improve, and effectively reduce scrappage.
