Technical Field

[0001] This utility model relates to the field of motor end cover processing technology, specifically a motor end cover forming and processing device. Background Technology

[0002] In modern industrial production, electric motors are widely used as the core power source for various mechanical equipment. As one of the key components of electric motors, the motor end cap plays a crucial role in the performance, stability, and service life of the motor. The drilling process for the mounting shaft hole of the end cap is also crucial. Therefore, a more efficient, precise, and environmentally friendly electric motor end cap forming and processing device is needed to adapt to market changes and industry development trends.

[0003] However, existing motor end cap forming and processing equipment still has some problems in use:

[0004] First, existing end cap drilling processing equipment lacks an adjustable structure for fixing the end cap. Since different end caps have different sizes, the non-adjustable fixing structure cannot be adapted to fixing different end caps, thus reducing the adaptability of the processing equipment.

[0005] Secondly, the drill bits in existing end cap drilling processing equipment are generally fixed. Since different end caps require drilling bearing mounting holes of different sizes, it is necessary to change to a suitable drill bit according to actual needs. Fixed drill bit installation is not conducive to quick drill bit replacement, which reduces the convenience of using the processing equipment. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-3 As shown, this utility model provides a motor end cap forming processing device, including a worktable 1. A support frame 9 with an inverted U-shaped cross-section is fixedly connected to the upper surface of the worktable 1. The inverted U-shaped support frame 9 can provide stable and structurally reasonable support for the components to be installed later, ensuring the overall stability of the device. A cylinder 5 is fixedly installed on the upper surface of the support frame 9. The output end of the cylinder 5 passes through the support frame 9 and is fixedly connected to a mounting shell 6. The cylinder 5 can precisely control the up and down movement of the mounting shell 6, thereby flexibly adjusting the drilling depth to meet the processing requirements of different end caps.

[0019] A DC motor 4 is fixedly installed inside the mounting housing 6. A ferrule 7 is fixedly connected to the output end of the DC motor 4. The drill bit body 8 is movably engaged inside the ferrule 7. A quick-release assembly 3 is provided between the ferrule 7 and the drill bit body 8. The DC motor 4 provides rotational power to the drill bit body 8 to complete the drilling operation.

[0020] The quick-installation assembly 3 includes components such as a positioning block 35, a pin 32, a positioning slot 34, a positioning sleeve 33, and a positioning pin 31. The positioning block 35 is fixedly installed on the upper surface of the drill bit body 8. The positioning block 35 is movably engaged in the sleeve 7. A positioning slot 34 is symmetrically opened on one side of the positioning block 35 to cooperate with the pin 32. The pin 32 and the positioning slot 34 are engaged to initially determine and fix the position of the drill bit body 8.

[0021] The positioning sleeve 33 is fixedly installed on one side of the ferrule 7. The positioning pin 31, which is used in conjunction with the pin 32, is movably inserted into the positioning sleeve 33. The positioning pin 31 is a magnetic pin, and the positioning sleeve 33 is a magnetic sleeve. The positioning pin 31 passes through the pin 32 and is magnetically connected to the positioning sleeve 33 to prevent the pin 32 from falling off accidentally. This further ensures that the drill bit body 8 is installed firmly and enables the drill bit body 8 to be quickly installed and removed, thus improving the ease of use of the processing device.

[0022] A centering and fixing mechanism 2 is provided on both the upper and lower surfaces of the worktable 1. The centering and fixing mechanism 2 aligns the fixed end cap with the drill bit body 8 in the center, facilitating the drilling of bearing mounting holes at the center of the end cap of the drill bit body 8 and ensuring the accuracy of the drilling position. The centering and fixing mechanism 2 includes a positioning frame 28, a servo motor 26, a rotating plate 27, a connecting rod 25, a vertical rod 24, a guide groove 21, a guide rod 23, and a fixing plate 22. The positioning frame 28 is fixedly installed on the lower surface of the worktable 1, and the servo motor 26 is fixedly installed in the inner cavity of the positioning frame 28, so that the positioning frame 28 provides certain support and positioning for the servo motor 26. The output end supporting the servo motor 26 is fixedly connected to the rotating plate 27, and the servo motor 26 drives the rotating plate 27 to rotate.

[0023] The connecting rod 25 is hinged to the lower surface of the rotating plate 27 via a rotating shaft, and the vertical rod 24 is hinged to the upper surface of the connecting rod 25 via a rotating shaft. The top end of the vertical rod 24 passes through the worktable 1 and is fixedly connected to the fixing plate 22. The rotating plate 27 drives the vertical rod 24 to move via the connecting rod 25, thereby flexibly adjusting the position of the fixing plate 22 according to the actual end cap size, stabilizing the end cap, and improving the applicability of the processing device.

[0024] The fixing plate 22 is a rubber anti-slip plate. The lower surface of the fixing plate 22 is slidably connected to the worktable 1. The rubber anti-slip plate 22 can increase the friction between the fixing plate and the end cap, and fix the end cap securely while avoiding damage to the surface of the end cap.

[0025] The guide groove 21 is formed on the upper surface of the worktable 1 and is used in conjunction with the vertical rod 24. The vertical rod 24 is slidably connected to the guide groove 21. The guide rod 23 is fixedly installed in the inner cavity of the guide groove 21 and is used in conjunction with the vertical rod 24. The vertical rod 24 is slidably sleeved on the outer surface of the guide rod 23. The guide groove 21 and the guide rod 23 can play a precise guiding role in the movement of the vertical rod 24, ensuring that the fixed plate 22 moves stably and is positioned accurately.

[0026] Working principle: First, before processing, the matching drill bit body 8 is installed on the processing device through the quick-installation component 3. The positioning block 35 is movably engaged with the ferrule 7, and the pin 32 is inserted into the positioning through groove 34 on one side of the positioning block 35 to initially fix the position of the drill bit body 8.

[0027] The positioning pin 31 passes through the pin 32 and is magnetically connected to the positioning sleeve 33 made of magnetic sleeve material, preventing the pin 32 from accidentally falling off, further ensuring that the drill bit body 8 is installed firmly and facilitating quick replacement of the matching drill bit body 8.

[0028] Next, the motor end cap to be processed is placed on the worktable 1. At this time, the centering and fixing mechanism 2 starts to work, the servo motor 26 starts, and its output end drives the rotating plate 27 fixedly connected to it to rotate. As the rotating plate 27 rotates, the connecting rod 25 will drive the vertical rod 24 to move along the guide groove 21 opened in the annular array on the upper surface of the worktable 1.

[0029] The guide rod 23, which is fixedly installed in the inner cavity of the guide groove 21, is sleeved on the outer surface of the vertical rod 24, providing precise guidance for the movement of the vertical rod 24. Driven by the vertical rod 24, the position of the fixing plate 22 can be flexibly adjusted according to the size of the end cap. The rubber anti-slip plate increases the friction between the plate and the end cap, thus firmly fixing the end cap and preparing it for subsequent processing.

[0030] After the end cap is fixed, the drilling operation is performed. The cylinder 5 is started, and its output end passes through the support frame 9 to push the mounting shell 6, which is fixedly connected to it, to move up and down. This precisely controls the drilling depth. The DC motor 4 inside the mounting shell 6 runs, and its output end drives the ferrule 7 to rotate. The drill bit body 8 inside the ferrule 7 rotates accordingly, generating drilling power to quickly drill.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
