Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically a surface polishing device for power adapter production. Background Technology

[0002] Polishing machines, also known as grinding machines, are commonly used for mechanical grinding, polishing, and waxing. Their working principle is as follows: an electric motor drives a sponge or wool polishing disc mounted on the machine to rotate at high speed. Due to the combined action of the polishing disc and polishing compound, friction is applied to the surface to be polished, thereby removing paint contaminants, oxide layers, and shallow scratches. The polishing disc's rotation speed is generally between 1500-3000 rpm, and is mostly continuously variable, allowing for adjustment as needed during operation.

[0003] In the production process of existing power adapters, polishing equipment is required to improve the appearance quality of the product, increase its gloss and ensure a smooth surface. However, existing polishing equipment lacks a structure for quick replacement of different polishing wheels, which makes it take a long time to change polishing wheels, resulting in production interruption. In addition, multiple polishing wheels need to be prepared before polishing work, which is inconvenient to carry. Based on the shortcomings of existing technology, this utility model designs a surface polishing device for power adapter production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a surface polishing device for power adapter production, which features a combination of polishing wheels that can be quickly replaced.

[0005] This utility model provides the following technical solution: a surface polishing device for power adapter production, including a handle, a motor assembly at the end of the handle, and a quick-change structure fixedly installed on one side of the outer surface of the handle; the quick-change structure includes a fixed handle, a rotating rod rotatably installed inside the fixed handle, a cross rod fixedly installed at the bottom of the rotating rod, polishing wheels rotatably installed at the four ends of the cross rod, a fixed ring fixedly installed inside the four polishing wheels, a threaded post fixedly installed inside the four fixed rings, threaded rods threaded inside the four threaded posts, and a throttle fixedly installed at one end of the four threaded rods.

[0006] As a preferred embodiment of this utility model, a sealing gasket is fixedly installed at the bottom of the motor assembly, and a threaded tube is rotatably installed inside the sealing gasket.

[0007] As a preferred embodiment of this utility model, one end of the threaded tube is fixedly connected to the output shaft of the motor assembly, and the threaded tube has a threaded groove inside.

[0008] As a preferred technical solution of this utility model, the outer surface of the motor assembly is provided with a dust collection structure on both sides, and the dust collection structure includes two fixing boxes and a storage box.

[0009] As a preferred embodiment of this utility model, two exhaust fans are provided on the top of the two fixing boxes, and the exhaust ports of the two exhaust fans are located at the bottom of the fixing boxes.

[0010] As a preferred embodiment of this utility model, a connecting pipe is fixedly installed on the top of the two fixed boxes, and the other end of the two connecting pipes is fixed to the storage box.

[0011] As a preferred embodiment of this utility model, the storage box is fixed on the top of the motor assembly, and the interior of the storage box is connected to two connecting pipes.

[0012] As a preferred embodiment of this utility model, a sealing cover is fixedly installed at the opening of the storage box.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This surface polishing device for power adapter production features a quick-change structure. During power adapter polishing, the polishing wheel can be quickly replaced to meet different polishing needs. Under normal conditions, the polishing wheel is connected to the threaded tube by aligning the threaded rod with the threaded tube and screwing it in. When the motor assembly drives the threaded tube to rotate, the polishing wheel rotates to complete the polishing work. When the polishing wheel needs to be replaced, after stopping the machine, the throttle is turned in the opposite direction to rotate the threaded rod in the threaded column and disengage it from the threaded tube. Then, the required polishing wheel is rotated to the underside of the motor assembly by moving the cross lever. After fixing it again, the polishing work can continue. This achieves the purpose of combining multiple polishing wheels and allowing for quick replacement.

[0015] 2. This surface polishing device for power adapter production uses a dust extraction structure. When the motor assembly drives the polishing process, the exhaust fans on both sides drive the air vents at the bottom of the fixed box to suck in the fine debris generated during polishing. The debris then passes through a connecting pipe into a storage box for storage. After polishing is completed, the sealing cover can be removed for cleaning. This achieves the collection of debris and dust generated during power adapter polishing, preventing dust from being inhaled by workers. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-5 A surface polishing device for power adapter manufacturing includes a handle 1, a motor assembly 2 at the end of the handle 1, and a quick-change structure 3 fixedly installed on one side of the outer surface of the handle 1. The quick-change structure 3 includes a fixed handle 31, a rotating rod 32 rotatably installed inside the fixed handle 31, a cross rod 33 fixedly installed at the bottom of the rotating rod 32, polishing wheels 34 rotatably installed at the four ends of the cross rod 33, fixed rings 35 fixedly installed inside the four polishing wheels 34, threaded posts 36 fixedly installed inside the four fixed rings 35, threaded rods 37 threaded inside the four threaded posts 36, and a throttle 38 fixedly installed at one end of the four threaded rods 37.

[0024] Please see Figure 1-2 A sealing gasket 5 is fixedly installed at the bottom of the motor assembly 2, and a threaded tube 6 is rotatably installed inside the sealing gasket 5. One top end of the threaded tube 6 is fixedly connected to the output shaft of the motor assembly 2, and a threaded groove is opened inside the threaded tube 6.

[0025] By aligning the threaded rod 37 with the threaded tube 6 and screwing it into the threaded tube 6 for fixation, the polishing wheel 34 can be connected to the threaded tube 6. Thus, when the motor assembly 2 drives the threaded tube 6 to rotate, the polishing wheel 34 can be rotated to complete the polishing work.

[0026] Please see Figure 1 and Figure 5 The motor assembly 2 has dust collection structures 4 on both sides of its outer surface. Each dust collection structure 4 includes two fixed boxes 41 and a storage box 44. Two exhaust fans 42 are mounted on the top of the two fixed boxes 41, with their exhaust ports located below the fixed boxes 41. Connecting pipes 43 are fixedly installed on the top of the two fixed boxes 41, with the other ends of the connecting pipes 43 fixed to the storage box 44. The storage box 44 is fixed to the top of the motor assembly 2, and its interior communicates with the two connecting pipes 43. A sealing cap 45 is fixedly installed at the opening of the storage box 44.

[0027] When the motor assembly 2 is driven to perform polishing work, the exhaust fans 42 on both sides can drive the air vent at the bottom of the fixed box 41 to suck in the fine debris generated during polishing. After passing through the connecting pipe 43, the debris enters the storage box 44 for storage. After polishing is completed, the sealing cover 45 can be removed for cleaning. This achieves the collection of debris and dust generated during the polishing of the power adapter, preventing dust from being inhaled by the staff.

[0028] Working principle: When a surface polishing device for power adapter production is used, under normal conditions, by aligning the threaded rod 37 with the threaded tube 6 and screwing it into the threaded tube 6 for fixation, the polishing wheel 34 can be connected to the threaded tube 6. Thus, when the motor assembly 2 drives the threaded tube 6 to rotate, the polishing wheel 34 will rotate, completing the polishing work. When it is necessary to replace the polishing wheel 34, the threaded rod 37 is rotated in the threaded post 36 and disengaged from the threaded tube 6 by turning the handle 38 in the opposite direction. At this time, the polishing wheel 34 to be used is rotated to the position directly below the motor assembly 2 by moving the cross rod 33. After fixing it again, the polishing work can continue. Then, when the motor assembly 2 drives the polishing work, the exhaust fans 42 on both sides drive the air vent at the bottom of the fixed box 41 to suck in the fine debris generated during polishing. After passing through the connecting pipe 43, it enters the storage box 44 for storage. After polishing is completed, the sealing cover 45 can be removed for cleaning. This achieves the collection of debris and dust generated during the polishing of the power adapter, preventing dust from being inhaled by the workers.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
