Description

Technical Field

[0001] The utility model relates to the technical field of motor production equipment, in particular to a fixing mechanism for a special-shaped motor. Background Art

[0002] The motor is the main component of a fan and is used to drive the fan impeller to rotate. In the common motor structure currently applied to fans, the motor is installed on the motor installation part of the fan housing, and the impeller is installed on the motor rotor. During the motor production and conveying process or the testing process, since the fan housing is relatively large and there are also fixing holes on the fan housing, it is convenient to hold or fix the fan housing, and then convey or test the motor.

[0003] However, for Figure 1 the special-shaped motor as shown, the impeller B is directly installed on the motor rotor. The diameter of the motor mounting plate A is smaller than the diameter of the impeller B, and there are no fixing holes on the motor mounting plate A. When conveying the motor or performing sound detection tests and electrical characteristic tests, if the motor mounting plate A is held by hand for testing, it is first very difficult to hold, and the motor is prone to slipping off during rotation. In addition, the rotating impeller B of the motor is easy to hit the hand.

[0004] Therefore, this special-shaped motor cannot hold or fix the fan housing for testing like other common motor structures, resulting in difficulty in fixing during the motor conveying or testing process. Summary of the Utility Model

[0005] The utility model mainly solves the technical problem that it is difficult to fix a special-shaped motor during the motor conveying or testing process, and proposes a fixing mechanism for a special-shaped motor to achieve the rapid assembly of the motor and facilitate the conveying and various tests of the motor.

[0006] The utility model provides a fixing mechanism for a special-shaped motor, including: a bottom plate, a spring, an outer cylinder structure and an inner cylinder structure;

[0007] A motor receiving groove is arranged on the top surface of the inner cylinder structure. The bottom of the inner cylinder structure is open, and inner cylinder struts are arranged axially on the inner cylinder structure. A spring is sleeved on the inner cylinder struts. A retaining pin is arranged on the outer wall of the inner cylinder structure;

[0008] The outer cylinder structure is rotatably sleeved outside the inner cylinder structure. A plurality of buckles are arranged circumferentially on the top of the outer cylinder structure. A clamping groove is opened on the side wall of the outer cylinder structure, and the retaining pin is placed in the clamping groove;

[0009] The bottom of the outer cylinder structure is fixedly connected to the bottom plate. The bottom of the inner cylinder strut extends out of the bottom plate. The bottom plate is in contact with the spring.

[0010] Preferably, the inner cylinder strut is fixed on the mounting seat after extending out of the bottom plate.

[0011] Preferably, the card slot is in an "L" shape.

[0012] Preferably, a plurality of protruding blocks are arranged on the outer periphery of the top surface of the inner cylinder structure.

[0013] For a special-shaped motor fixing mechanism provided by the present utility model, after placing the motor on the inner cylinder structure, rotate the outer cylinder structure counterclockwise. The pin moves along the "L"-shaped card slot. Under the action of the spring resilience, drive the bottom plate and the outer cylinder structure to move downward, and the buckle presses down on the protrusion on the outer periphery of the motor mounting plate, thereby fixing the motor. The present utility model presses and fixes the motor mounting plate through the rotation of the outer cylinder structure and the resilience of the spring, thereby realizing the rapid assembly of the motor, facilitating the transportation and various tests of the motor. The top surface of the inner cylinder structure is provided with a motor receiving groove, and the motor receiving groove can place the motor. A plurality of protruding blocks cover the side surface of the motor mounting plate.

Detailed Embodiments

[0020] To make the technical problems solved by the present utility model, the technical solutions adopted and the achieved technical effects clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model are shown in the drawings rather than all the content.

[0021] As Figure 2-4 shown, a special-shaped motor fixing mechanism provided by an embodiment of the present utility model includes: a bottom plate 4, a spring 6, an outer cylinder structure 2, and an inner cylinder structure 3.

[0022] A motor receiving groove 10 is provided on the top surface of the inner cylinder structure 3, and a plurality of protruding blocks 11 are provided on the outer periphery of the top surface of the inner cylinder structure 3. The motor receiving groove 10 can place a motor. Specifically, a motor mounting plate A is placed in the motor receiving groove 10, and the plurality of protruding blocks 11 cover the side surface of the motor mounting plate A.

[0023] As Figure 5 shown, the bottom of the inner cylinder structure 3 is open, and an inner cylinder support column 9 is axially provided on the inner cylinder structure 3; the spring 6 is sleeved on the inner cylinder support column 9; a retaining pin 8 is provided on the outer wall of the inner cylinder structure 3.

[0024] The outer cylinder structure 2 is rotatably sleeved outside the inner cylinder structure 3, and a plurality of buckles 7 are circumferentially provided on the top of the outer cylinder structure 2; a card slot 5 is opened on the side wall of the outer cylinder structure 2, and the card slot 5 is in an "L" shape; the retaining pin 8 is placed in the card slot 5.

[0025] The bottom of the outer cylinder structure 2 is fixedly connected to the bottom plate 4; the bottom of the inner cylinder support column 9 extends out of the bottom plate 4, and the inner cylinder support column 9 is in contact with the bottom plate 4 but not fixed; the bottom plate 4 is in contact with the spring 6. Among them, after the inner cylinder support column 9 extends out of the bottom plate 4, it is fixed on the mounting seat 1, and the special-shaped motor fixing mechanism of the present utility model can be installed on a conveyor line or a testing device through the mounting seat 1.

[0026] The working process of the special-shaped motor fixing mechanism of the present utility model: In the initial state, the retaining pin 8 is placed at the rightmost end of the card slot 5 (as Figure 3 ), the spring 6 is in a compressed state under the clamping action of the top of the inner cylinder structure 3 and the bottom plate 4. At this time, the buckle 7 is not engaged, and there is a gap between the buckle 7 and the inner cylinder structure 3, so that the motor can be conveniently placed; after the motor is placed on the inner cylinder structure 3, the outer cylinder structure 2 is rotated counterclockwise, and the retaining pin 8 moves along the "L"-shaped card slot 5 to the leftmost end. The leftmost end of the card slot 5 has a longitudinal length. Under the action of the resilience of the spring 6, the bottom plate 4 and the outer cylinder structure 2 are driven to move downward, and the buckle 7 presses down the protrusion on the outer periphery of the motor mounting plate A, thereby fixing the motor. The retaining pin 8 is located at the top of the card slot 5 for limiting, and it is in a pressing state at this time. After the motor is fixed, the motor can be transported or tested, etc. When the motor needs to be removed, the outer cylinder structure 2 is rotated clockwise along the "L"-shaped card slot 5, and the buckle 7 is lifted to release the motor.

[0027] The present utility model presses the motor mounting plate A by rotating the outer cylinder structure 2 and the resilience of the spring 6, thereby realizing the rapid assembly of the motor and facilitating the transportation and various tests of the motor.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: modifying the technical solutions recorded in the foregoing embodiments, or equivalently replacing some or all of the technical features therein, does not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
