Abstract
The invention discloses a fixing device of a variable-frequency ventilation motor, comprising a fixed plate. The fixed plate is in a rectangular flat structure matched with the inside diameter of a hood, a central end of the fixed plate is fixed on a variable-frequency motor, the fixed plate is provided with a ventilation hole, reinforcing members are arranged on the two sides of the fixed plate, two ends of the fixed plate are both fixed on a connecting member welded on the inner wall of the hood, and through holes are arranged on the two ends of the fixed plate, the corresponding connecting member is also provided with a through hole, the fixing device of the variable-frequency ventilation motor is provided with the fixed plate with the rectangular flat structure, and the connecting member is fixed on the inner wall of the hood matched with the fixed plate which can be stably fixed on the variable-frequency motor and the connecting member through a bolt. The fixing device of the variable-frequency ventilation motor has the advantages of simple structure, cost saving, stable fixation and high reliability.
Description
Technical field
The present invention relates to a kind of fixture, particularly relate to the fixture of the dynamo-electric machine of a kind of variable-frequency ventilation.
Background technology
As everyone knows, the variable-frequency ventilation machine is applied in people's the life widely, general variable-frequency ventilation machine comprises hood and variable-frequency motor, described variable-frequency motor need be fixed in the hood by fixture, traditional variable-frequency motor fixture generally comprises fixed head and most connecting rod, offer through hole on the described fixed head, described connecting rod is generally cylindrical structure, one end of described connecting rod is fixed on the fixed head, and the length of described connecting rod cooperates the internal diameter setting of hood, coupler link offers through hole on the described hood, utilize bolt that the other end of connecting rod is fixed on the hood, there is following shortcoming in the fixture of this variable-frequency motor in concrete processing and assembling process:
1) Machining of Connecting Rod complex procedures, assemble loaded down with trivial details, because of connecting rod plays main rigid support fixation, so what connecting rod two ends fixing must be very firm is fixed between fixed head and the hood, one end of connecting rod will cooperate the thickness of fixed head to offer draw-in groove, by draw-in groove connecting rod one end is arranged on the fixed head, fixing by welding again, its other end also will offer helicitic texture;
2) fixing poor reliability, to have bolt to cause ventilation blower to be difficult for fixing because of exposing on the ventilation blower hood, and if the connecting rod that is provided with have one loosening, variable-frequency motor will produce bigger vibrations when work, can't operate as normal;
3) complex structure, cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of fixing device of variable-frequency ventilation motor, described fixing device of variable-frequency ventilation motor has simple in structure, and is fixed, saves the characteristics of cost.
The objective of the invention is to be achieved through the following technical solutions:
Fixing device of variable-frequency ventilation motor, it comprises fixed head, and wherein, described fixed head cooperates the setting of hood internal diameter, and the two ends of described fixed head all are fixed on the connector, and described connector is fixed in the hood inwall.
Described fixed head is the rectangle flat structure, and its center-side is fixed on the variable-frequency motor, and also offers ventilation hole on the described fixed head, and the both sides of described fixed head are provided with reinforcement.
Described connector is welded on the hood inwall.
The two ends of described fixed head offer through hole, also offer through hole on the corresponding connector, by bolt fixed head are fixed on the connector.
Beneficial effect of the present invention is, described fixing device of variable-frequency ventilation motor is provided with the fixed head of rectangle flat structure, and cooperate fixed head to be fixed with connector in the hood inwall, fixed head firmly can be fixed on variable-frequency motor and the connector by bolt, not only simple in structure, save cost; And fixing firm, the reliability height.

Embodiment
Please refer to Fig. 1 to shown in Figure 4, in present embodiment, described fixing device of variable-frequency ventilation motor is used for variable-frequency motor 3 is fixed on the hood 1, described variable-frequency motor 3 is provided with flabellum 2, it comprises fixed head 4 and connector 6, described fixed head 4 is fixed on the connector 6, described connector 6 is fixedly welded on the inwall of hood 1, described fixed head 4 cooperates hood 1 internal diameter to be set to the rectangle flat structure, its center-side offers most through holes 5, so that fixed head 4 is fixed on the variable-frequency motor 3 by bolt 7, and also offer ventilation hole 40 on the described fixed head 4, the both sides of described fixed head 4 are provided with reinforcement 41, so that fixed head 4 has better rigidity, and the correspondence position of described fixed head 4 and connector 6 junctions all offers through hole 5, utilizes bolt 7 to pass through hole 5 fixed head 4 is fixed on the connector 6.
During installation, only need variable-frequency motor 3 is put into hood 1, utilize bolt 7 that fixed head 4 is fixed on the variable-frequency motor 3 then, utilize bolt 7 to be fixed on the connector 6 at the two ends of fixed head 4 at last and get final product.
Described fixing device of variable-frequency ventilation motor is easy accessibility not only, can enhance productivity about 80%, and simple in structure, can save about 50% raw material, and is fixing firm, the reliability height.
