Description

Technical Field

[0001] The utility model relates to the technical field of production of drive motor brush end covers, in particular to a milling fixture for the brush end covers of a vehicle engine drive motor. Background Art

[0002] The brush end cap of a drive motor is a component inside the motor that secures and protects the brushes. Brushes are the components of the motor that transmit electrical energy, contacting the motor's rotor and transferring energy through the current. Typically made of metal or plastic, these end caps are installed at the ends of the motor to secure the brushes and prevent dust and debris from entering the motor. During the production process, these end caps are mounted on a milling machine for cutting.

[0003] Since the end caps used in motors of different models may have different sizes, the existing clamping device cannot flexibly adapt to end caps of different sizes, resulting in the need to frequently replace the clamps during the production process, increasing production costs and process adjustment time, and reducing production efficiency. Therefore, there is a problem of inconvenience in clamping end caps of different sizes. Utility Model Content

[0004] The main purpose of the utility model is to provide a milling fixture for a brush end cover of a vehicle engine drive motor, which can effectively solve the problems raised in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 - Figure 4 As shown, a vehicle engine drive motor brush end cover milling fixture includes a mounting housing 1, a clamping mechanism 2 and a filter mechanism 3. The filter mechanism 3 is slidably connected to the upper surface of the mounting housing 1, and the clamping mechanism 2 is fixedly connected to the upper surface of the filter mechanism 3. The filter mechanism 3 includes a sliding baffle 302 slidably connected to the upper surface of the mounting housing 1. The clamping mechanism 2 includes a clamping seat 203 fixedly connected to the upper surface of the sliding baffle 302. The clamping mechanism 2 also includes a through hole 205 opened on the upper surface of the mounting housing 1. The outer surface of the through hole 205 is slidably connected to the sliding block 204, and the upper surface of the sliding block 204 is fixedly connected to the lower surface of the sliding baffle 302, wherein three groups of through holes 205 are opened on the upper surface of the mounting shell 1, and the angle between each two adjacent through holes 205 is one hundred and twenty degrees, wherein the outer surface of the sliding block 204 is fixedly connected to the limiting block 212, and the outer surface of the limiting block 212 is slidably connected to the inner wall of the mounting shell 1, and the limiting block 212 can prevent the sliding block 204 from separating from the through hole 205.

[0024] In order to facilitate the clamping of drive motor brush end covers of different sizes, the outer surface of the sliding block 204 is hinged with a connecting rod 206, and the other end of the connecting rod 206 is hinged with a connecting plate 207. The outer surface of the connecting plate 207 is threadedly connected to a threaded rod 208. The threaded rod 208 rotates to drive the connecting plate 207 to slide up and down along the outer surface of the threaded rod 208, so that the sliding block 204 can drive the sliding baffle 302 to slide along the direction of the through hole 205, thereby facilitating the clamping of drive motor brush end covers of different sizes. The upper end of the threaded rod 208 is rotatably connected to the inner wall of the mounting shell 1, and the inner wall of the mounting shell 1 is fixedly connected to the reduction motor 210, and the output shaft of the reduction motor 210 is fixedly connected to the small gear 211, and the lower end of the threaded rod 208 is fixedly connected to the large gear 209, and the outer surface of the large gear 209 is connected to the small gear The outer surface of 211 is meshed and connected, and the large gear 209 and the threaded rod 208 are meshed by starting, wherein the lower ends of the large gear 209 and the small gear 211 are rotatably connected to the inner wall of the mounting shell 1, so that the reduction motor 210 can be arranged inside the mounting shell 1, thereby facilitating the protection of the reduction motor 210, wherein the outer surface of the reduction motor 210 is electrically connected to the control panel 202 through a wire, the outer surface of the control panel 202 is fixedly connected to the inner wall of the mounting shell 1, and the button of the control panel 202 is arranged on the outer surface of the mounting shell 1, and the reduction motor 210 can be regulated by pressing the button of the control panel 202 on the outer surface of the mounting shell 1, and the clamping seat 203 adopts a stepped shape, and the outer surface of the clamping seat 203 is fixedly connected to the rubber pad 201, which facilitates the protection of the drive motor brush end cover.

[0025] It is worth mentioning that when the reduction motor 210 is started, the output shaft of the reduction motor 210 drives the threaded rod 208 to rotate, and the rotation of the threaded rod 208 drives the connecting plate 207 to slide up and down along the outer surface of the threaded rod 208. The sliding of the connecting plate 207 drives one end of the three groups of connecting rods 206 to slide up and down, so that the connecting rod 206 can push and pull the outer surface of the sliding block 204, so that the sliding block 204 can slide along the outer surface of the through hole 205. The sliding of the sliding block 204 drives the sliding baffle 302 to slide, so that the three groups of clamping seats 203 can approach or move away from each other. With the stepped clamping seat 203, the drive motor brush end covers of different sizes can be clamped.

[0026] In order to facilitate heat dissipation of the device in the installation shell 1, the filtering mechanism 3 also includes a blocking grille 301 fixedly connected to the outer surface of the installation shell 1, and the inner wall of the installation shell 1 is fixedly connected to a filter plate 303. The outer surface of the filter plate 303 is in contact with the outer surface of the blocking grille 301. The length of the sliding baffle 302 is greater than the length of the through hole 205. The filter plate 303 and the blocking grille 301 are used to prevent debris from entering the interior of the installation shell 1, and at the same time, it is convenient to dissipate heat for the reduction motor 210.

[0027] It is worth mentioning that the outer surface of the through hole 205 can be blocked by the sliding baffle 302, and the blocking grille 301 and the sliding baffle 302 can block one side of the installation shell 1, thereby preventing processing debris from entering the installation shell 1. At the same time, the blocking grille 301 and the sliding baffle 302 facilitate cooling of the reduction motor 210 and the control panel 202 in the installation shell 1, thereby improving the service life of the reduction motor 210 and the control panel 202.

[0028] Working principle: By starting the reduction motor 210, the output shaft of the reduction motor 210 drives the threaded rod 208 to rotate, and the rotation of the threaded rod 208 drives the connecting plate 207 to slide up and down along the outer surface of the threaded rod 208, and the sliding of the connecting plate 207 drives one end of the three groups of connecting rods 206 to slide up and down, so that the connecting rod 206 can push and pull the outer surface of the sliding block 204, so that the sliding block 204 can slide along the outer surface of the through hole 205, and the sliding block 204 slides and drives the sliding baffle 302 to slide, so that the three groups of clamping seats 203 can approach or move away from each other. With the stepped clamping seat 203, the drive motor brush end covers of different sizes can be clamped, and the sliding baffle 302 can block the outer surface of the through hole 205, as well as block the grille 301 and the sliding baffle 302. One side of the mounting shell 1 can be shielded to prevent processing debris from entering the mounting shell 1. At the same time, the blocking grille 301 and the sliding baffle 302 facilitate cooling of the reduction motor 210 and the control panel 202 in the mounting shell 1, thereby increasing the service life of the reduction motor 210 and the control panel 202.
