Abstract
The utility model provides a fastening structure of an air-conditioner motor end cover, which comprises a first tensile end cover, a second tensile end cover and fastening elements for connecting the two tensile end covers, wherein the fastening elements are preferable four flat-head semi-hollow rivets, and blind holes are arranged in the rivets; the thicknesses (A) of the heads of the rivets are 1.8mm to 2.2mm, the diameters (phiB) of the heads of the rivets are 5.8mm to 7.2mm, the lengths (C) of the rivets are 5.5mm to 6.8mm, the diameters (phiD) of the rivets are 4.0mm to 4.4mm, the depths (E) of the blind holes are 3.6mm to 4.6mm, and the diameters (phiF) of the blind holes are 2.6mm to 3.0mm; the bottoms of the blind holes are in conical shapes; and the base angles (G) of the shaft cross sections of the bottom of the conical shapes are 5 degrees to 15 degrees. According to the rivet fastening structure of the air-conditioner fan motor tensile end cover, the number of production personnel is reduced based on an original screw fastening structure, so that automatic production is realized to a greater extent, the product quality and the consistency of the product quality are improved, and the production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of fastening structure that is used for the stretching end cap of air conditioner motor, belongs to the air conditioner motor technical field.
Background technology
Existing air conditioner motor is carrying out connection between the first stretching end cap 1 ' and the second stretching end cap 2 ' when fastening; Generally carry out fastening through screw 3 '; Shortcoming below this fastening structure exists: 1, each tightening member comprises screw, nut and three parts of spring washer, and material cost is higher; 2, need four workman's mounting spring packing rings and nut, workman's locking nut, cost of labor is higher; 3, can only once lock a nut, the concentricity of motor stator and rotor can not get guaranteeing that the electromagnetic noise and the bearing of motor are bigger that the quality of motor can not get guaranteeing; 4, operate through manual work, production efficiency is lower.
The utility model content
The purpose of the utility model is the defective to prior art, and a kind of fastening structure of air conditioner motor end cover is provided, with the mechanization production of the fastening operation of installation that realizes air conditioner motor end cover.
For solving the problems of the technologies described above; Technical scheme below the utility model has adopted: the fastening structure that designs a kind of air conditioner motor end cover; Comprise the first stretching end cap, the second stretching end cap and the tightening member that is connected said two stretching end caps, wherein said tightening member is a rivet.
Said rivet is preferably a plurality of, is preferably four.
Preferably, said rivet is the tack semitubular rivet, has blind hole in its nail body; Wherein, the ailhead thickness (A) of this rivet is 1.8-2.2mm, and ailhead diameter (φ B) is 5.8-7.2mm; Nail height degree (C) is 5.5-6.8mm; Nail body diameter (φ D) is 4.0-4.4mm, and blind hole depth (E) is 3.6-4.6mm, and blind hole diameter (φ F) is 2.6-3.0mm; It is conical that the bottom of blind hole is, and the base angle of the shaft section of this conical lower section (G) is 5 °-15 °.
The air conditioner motor end cover fastening structure of the utility model has following advantage with respect to original screw fastening structure:
1, only need a workman that rivet is installed, workman's riveting rivet has been saved three workmans on the original basis, has directly reduced the motor production cost.
2, four rivets of riveting simultaneously, the concentricity of motor stator and rotor can be guaranteed, and the electromagnetic noise of motor and bearing noise are littler, and the quality of motor more can be guaranteed.
3, be fit to adopt mechanization production, omit the phenomenon of operation when having stopped manual operation, better guarantee the quality of product; Also greatly improved simultaneously operating efficiency; And homogeneity of product is better, has improved the disposable qualification rate of product, has reduced the motor production cost.
4, each restraint location only needs parts of rivet, obtains on the material cost reducing, and has directly reduced the motor production cost.
