Description

Technical Field

[0001] This application relates to the field of motor end caps, and more particularly to a high-strength motor end cap. Background Technology

[0002] In the field of motor manufacturing and assembly, especially in motors with electromagnetic braking functions, a brake assembly is usually required on the outside of the motor end cover. A common existing technical solution is to machine threaded holes on the outside of the motor end cover, and correspondingly, to have through holes on the brake disc (or armature disc). During installation, the through holes and threaded holes on the brake disc need to be precisely aligned, and then bolts are used to pass through the through holes of the brake disc and screw them into the threaded holes, thereby fixing the brake disc to the motor end cover.

[0003] However, this fixing method has significant drawbacks: First, during assembly, operators must manually adjust the angle and position of the brake disc to ensure that all through holes on the disc are perfectly aligned with all threaded holes. This process lacks effective auxiliary positioning guidance and relies entirely on the operator's visual observation and feel, making it extremely inconvenient. Second, while aligning the holes, the brake disc must be temporarily stabilized by hand or with the aid of tools to smoothly screw in the bolts. This not only increases the complexity of the operation but also greatly reduces assembly efficiency, making it difficult to adapt to the pace of modern automated production lines.

[0004] Therefore, a new connection structure design is urgently needed to solve the problems of inconvenient hole alignment and low assembly efficiency. Utility Model Content

[0005] To improve assembly efficiency, this application provides a high-strength motor end cover.

[0006] The high-strength motor end cover provided in this application adopts the following technical solution: A high-strength motor end cap includes a body and a mounting block. The mounting block is fixedly connected to one side of the body. A positioning block is fixedly connected to the end of the mounting block opposite to the body. The end face of the positioning block opposite to the axis of the body is used to abut against the inner wall of the brake pad. The end of the mounting block opposite to the body is provided with a threaded opening, which is located on the outer periphery of the positioning block.

[0007] By adopting the above technical solution, the positioning block abuts against the inner wall of the brake pad to achieve initial positioning of the brake pad installation. Rotating the brake pad aligns the through hole on the brake pad with the threaded hole, and the brake pad is fixed to the body by screws, which improves the hole alignment efficiency and assembly efficiency.

[0008] Preferably, there are multiple mounting blocks, and the multiple mounting blocks are evenly spaced around the axis of the body.

[0009] By adopting the above technical solution, multiple mounting blocks correspond to multiple positioning blocks, and the brake pads are sleeved on the outer periphery of multiple positioning blocks, which facilitates the positioning and installation of the brake pads, so that the through holes on the brake pads are aligned with the threaded holes, and the brake pads are fixed to the body by screws, thereby improving the hole alignment efficiency and assembly efficiency.

[0010] Preferably, it further includes a ring body, which is sleeved on the outer periphery of multiple mounting blocks. The ring body is fixedly connected to one side of the main body, and the mounting blocks are fixedly connected to the inner wall of the ring body. The end face of the ring body facing away from the main body is used to abut against the brake pad.

[0011] By adopting the above technical solution, it is easy to install the brake pads. The ring body connects multiple mounting blocks together, which improves the overall structural strength of the mounting blocks, making the mounting blocks less prone to damage under stress and extending the service life of the motor end cover.

[0012] Preferably, it further includes reinforcing ribs, which are disposed on the outer periphery of the ring and are fixedly connected to the outer wall of the ring and the outer wall of the body.

[0013] By adopting the above technical solution, the reinforcing rib improves the connection strength between the ring and the body, thereby increasing the overall structural strength of the motor end cover, making it less prone to damage, and extending the service life of the motor end cover.

[0014] Preferably, there are multiple reinforcing ribs, and the multiple reinforcing ribs are evenly spaced around the axis of the ring body.

[0015] By adopting the above technical solution, multiple reinforcing ribs are evenly stressed, which improves the overall structural strength of the motor end cover, making it less prone to damage and extending its service life.

[0016] Preferably, the mounting block has an abutment groove at one end away from the main body. The abutment groove is located between the threaded opening and the positioning block, and the abutment groove is used for the protrusion on the brake pad to be inserted.

[0017] By adopting the above technical solution, the abutment groove positions the brake pads for installation, increases the contact area between the body and the brake pads, and improves the structural strength of the connection between the two.

[0018] Preferably, it also includes a limiting plate, which is connected to the groove wall of the abutment groove, and the limiting plate is used for the protrusion on the brake pad to abut.

[0019] By adopting the above technical solution, after the brake pad is sleeved on the outer periphery of the positioning block, the protrusion is embedded in the abutment groove. By rotating the brake pad, the protrusion abuts against one side of the limiting plate. At this time, the through port and the threaded port are aligned, which improves the hole alignment efficiency and the assembly efficiency.

[0020] Preferably, it also includes a spring, the bottom of the abutment groove is provided with a placement groove, the limiting plate is slidably connected to the groove wall of the placement groove, one end of the spring is fixedly connected to the bottom of the placement groove, and the other end of the spring is fixedly connected to the limiting plate.

[0021] By adopting the above technical solution, when installing the brake pad, when the protrusion abuts against the end of the limiting plate away from the spring, the spring contracts and the brake pad rotates. When the protrusion moves away from the limiting plate, the spring returns to its original position. The limiting plate is used for the brake pad to abut against, which improves the hole alignment efficiency and assembly efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The positioning block abuts against the inner wall of the brake pad to achieve initial positioning of the brake pad installation. Rotate the brake pad so that the through hole on the brake pad is aligned with the threaded hole. The brake pad is then fixed to the body by screws, which improves the hole alignment efficiency and assembly efficiency. 2. Multiple mounting blocks correspond to multiple positioning blocks. The brake pads are fitted around the outer periphery of the multiple positioning blocks, which facilitates the positioning and installation of the brake pads. This ensures that the through holes on the brake pads are aligned with the threaded holes, and the brake pads are fixed to the body by screws, improving hole alignment efficiency and assembly efficiency. 3. After the brake pad is fitted onto the outer periphery of the positioning block, the protrusion is embedded in the abutment groove. Rotate the brake pad so that the protrusion abuts against one side of the limiting plate. At this time, the through port and the threaded port are aligned, which improves the hole alignment efficiency and assembly efficiency. Attached Figure Description

In this embodiment, there are three mounting blocks 2; in other embodiments, there may be four mounting blocks 2.

[0029] A positioning block 21 is fixedly connected to the end of the mounting block 2 facing away from the main body 1. The end face of the positioning block 21 facing the axis of the main body 1 is flush with the end face of the mounting block 2 facing the axis of the main body 1. The end face of the positioning block 21 facing away from the axis of the main body 1 is used to abut against the inner wall of the brake pad. The end of the positioning block 21 facing away from the main body 1 is provided with a chamfer, which is used to guide the brake pad. The end of the mounting block 2 facing away from the main body 1 is provided with a threaded opening 22, which is located on the outer periphery of the positioning block 21.

[0030] Reference Figure 1 The ring 3 is sleeved on the outer periphery of multiple mounting blocks 2. The ring 3 is coaxially arranged with the body 1. The ring 3 is fixedly connected to one side of the body 1. The mounting blocks 2 are fixedly connected to the inner wall of the ring 3. The end face of the mounting block 2 away from the body 1 is flush with the end face of the ring 3 away from the body 1.

[0031] A reinforcing rib 4 is disposed on the outer periphery of the ring body 3, and is fixedly connected to the outer wall of the ring body 3 and the outer wall of the body 1. Multiple reinforcing ribs 4 are provided, and are evenly spaced around the axis of the ring body 3. The length direction of the reinforcing rib 4 is along a radial direction of the body 1, and the width of the reinforcing rib 4 decreases as it moves away from the axis of the body 1.

[0032] Reference Figure 1 The mounting block 2 has an abutment groove 23 at one end opposite to the main body 1.
