Description

Technical Field

[0002] At present, the end cover is a rear cover installed behind the motor body. The quality of the end cover affects the quality of the motor. During the motor manufacturing process, external force is required to press the end cover onto the motor body. Since manual press-fitting of the end cover is time-consuming, labor-intensive and inefficient, most companies use press-fitting equipment to press-fit the end cover. For example, a motor end cover press-fitting equipment is disclosed in the Chinese patent with publication number CN215772880U. In some existing motors, such as but not limited to blower motors, the end cover is connected to the motor body by a buckle. When the press-fitting equipment presses the buckle on the end cover, there is a risk that the buckle on the end cover will be broken due to excessive press-fitting force, which will cause the end cover to be damaged and scrapped, resulting in unnecessary economic losses.

[0042] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0043] like Figures 1 to 6 As shown, an end cover press-fitting device for a blower motor is used to press-fit an end cover 2 having a buckle 1 onto a motor body 3, and comprises a frame 4, a moving device 5, a press-fitting seat 6, an adsorption component 7, a pressing block component 8 corresponding to the buckle 1 on the end cover 2, and an elastic member 9 corresponding to the pressing block component 8;

[0044] The adsorption component 7 is connected to the press-fit seat 6;

[0045] The press-fit seat 6 is connected to the moving device 5;

[0046] The moving device 5 is connected to the frame 4, and is used to drive the press-fitting seat 6 to move to the material taking position so that the adsorption component 7 on the press-fitting seat 6 adsorbs the end cover 2 to be installed. The moving device 5 is also used to drive the press-fitting seat 6 to move to the press-fitting position and then drive the end cover 2 adsorbed by the adsorption component 7 to move to press on the motor body 3;

[0047] The pressing block component 8 is slidably connected to the press-fitting seat 6 and is used to resist the corresponding buckle 1 on the end cover 2 sucked by the adsorption component 7;

[0048] The elastic member 9 is connected to the corresponding pressing block component 8 and is used to apply elastic force to the corresponding pressing block component 8 to drive the corresponding pressing block component 8 to press the corresponding buckle 1, and then the corresponding buckle 1 is pressed on the motor body 3 through the pressing block component 8. Specifically, first, the moving device 5 drives the press-fitting seat 6 to move to the material taking position, such as Figure 2 As shown, at this time, the adsorption component 7 on the press-fitting seat 6 abuts against the end cover 2 to be installed and adsorbs the end cover 2 to be installed, and at the same time, the pressing block component 8 is driven by the elastic force of the elastic member 9 to press the corresponding buckle 1 on the end cover 2; then the moving device 5 drives the press-fitting seat 6 to move to the press-fitting position and then presses the end cover 2 adsorbed by the adsorption component 7 onto the motor body 3, as shown in FIG. Figure 1 As shown, at this time, under the elastic force applied by the elastic member 9, the pressing block component 8 presses the corresponding buckle 1 and buckles the buckle 1 on the motor body 3. When the pressure of the pressing block component 8 on the buckle 1 is too large, the pressing block component 8 will compress the elastic member 9 and retreat upward, thereby avoiding the buckle 1 from being crushed due to excessive pressure on the buckle 1, avoiding the buckle 1 from being broken when the end cover 2 is pressed and installed, and avoiding unnecessary economic losses.

[0049] More specifically, the motor body 3 has a tongue corresponding to the buckle 1, and after the end cover 2 is pressed onto the motor body 3, the buckle 1 clamps the corresponding tongue to connect the end cover 2 to the motor body 3. In this embodiment, the adsorption component 7 can be a negative pressure suction cup, and the end cover 2 can be the end cover 2 in the blower motor.

[0055] The lifting cylinder 12 is connected to the frame 4, connected to the lifting seat 10 and is used to drive the lifting seat 10 to move up and down, thereby driving the transverse seat 11 and the press-fitting seat 6 to move up and down; specifically, the moving device 5 is used to drive the press-fitting seat 6 to move in the vertical and horizontal directions, thereby driving the press-fitting seat 6 to move to the material picking position and the press-fitting position.

[0061] The elastic member 9 is sleeved on the corresponding sliding rod 18, the upper end of the elastic member 9 is against the press-fitting seat 6, and the lower end of the elastic member 9 is against the block 17. The elastic member 9 is used to apply elastic force to the block 17 to drive the block 17 to press the upper end of the buckle 1 downward and then press the buckle 1 onto the motor body 3 through the block 17; specifically, when the moving device 5 drives the press-fitting seat 6 to move to the press-fitting position, the end cover 2 sucked by the adsorption component 7 is pressed on the motor body 3, and under the drive of the elastic member 9, the block 17 presses the corresponding buckle 1 and presses the buckle 1 onto the motor body 3; when the pressure of the block 17 on the buckle 1 is too large, the elastic member 9 will be compressed and the block 17 will move upward and give way, thereby avoiding excessive pressure on the buckle 1 and crushing the buckle 1.

At the same time, the block 17 is pressed against the upper end of the corresponding buckle 1 on the end cap 2 under the elastic force of the elastic member 9. Then the transverse cylinder 13 and the lifting cylinder 12 drive the press-fitting seat 6 to move to the press-fitting position, and the end cover 2 sucked by the adsorption component 7 is pressed on the motor body 3 in the second discharge mechanism in the press-fitting position, and under the drive of the elastic member 9, the block 17 presses the corresponding upper end of the buckle 1 and presses the buckle 1 on the motor body 3.

[0075] In summary, first, the moving device 5 drives the press-fitting seat 6 to move to the material-taking position, at which time the adsorption component 7 on the press-fitting seat 6 abuts against and absorbs the end cover 2 to be installed, and at the same time, the pressing block component 8 is driven by the elastic force of the elastic member 9 to press against the corresponding buckle 1 on the end cover 2; then the moving device 5 drives the press-fitting seat 6 to move to the press-fitting position and then presses the end cover 2 adsorbed by the adsorption component 7 onto the motor body 3, at which time, under the elastic force applied by the elastic member 9, the pressing block component 8 presses the corresponding buckle 1 and presses the buckle 1 onto the motor body 3.
