Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a motor housing inner wall cleaning device. Background Technology

[0002] As the core protective component of a motor, the motor housing requires thorough cleaning of its inner and outer surfaces during manufacturing or refurbishment to remove residual cutting fluid, metal shavings, oil, dust, and other impurities from the processing. This is crucial for ensuring the quality of subsequent painting, assembly, and other processes, as well as the final performance and lifespan of the motor. On automated production lines, specialized cleaning equipment is used to complete this process. In a typical automated cleaning process, the first step is to stably and reliably position and fix the motor housing to be cleaned using a clamping mechanism. The firmness and accuracy of the clamping directly affect the effective operation of the subsequent cleaning mechanism and the safety and efficiency of the entire cleaning process.

[0003] However, many existing cleaning devices have common shortcomings in the design of their clamping mechanisms. They often use rigid jaws with fixed strokes to clamp the workpieces. This design results in poor equipment versatility when cleaning motor housings of different models and outer diameters. The devices cannot clamp effectively or require a lot of time to change tooling fixtures of different specifications, which seriously restricts the flexibility and efficiency of production. At the same time, when the rigid jaws come into contact with the surface of the motor housing, the small contact area and the difficulty in controlling the pressure can easily cause indentations or scratches on the surface of the workpiece, affecting the appearance and quality of the product.

[0004] Therefore, this utility model proposes a motor housing inner wall cleaning device to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of poor versatility of clamping mechanism, inability to adapt to workpieces with different outer diameters, and easy damage to workpiece surface during clamping in the existing motor housing inner wall cleaning device, this utility model aims to provide a motor housing inner wall cleaning device with improved structure that can effectively solve the above problems.

[0006] This utility model provides a motor housing inner wall cleaning device, including: a cleaning tank, a fixing mechanism, a sweeping mechanism, a hollow plate disposed in the fixing mechanism, a first electric push rod, a first slide rail, a second slide rail, a first slider, a V-shaped rotating plate, a second slider, a T-shaped piece, and a flexible clamping plate.

[0007] The first electric push rod is installed inside the hollow plate, the first slide rail is fixedly connected to the outer wall of the hollow plate in the vertical direction, and the second slide rail is fixedly connected to the lower part of the outer wall of the hollow plate in the horizontal direction.

[0008] Furthermore, the first slider and the first slide rail are combined by a sliding fit and are connected to the pushing end of the first electric push rod. The middle of the corner of the V-shaped rotating plate is rotatably connected to the first slider, and the two ends of the bottom of the V-shaped rotating plate are rotatably connected to the second slider. The second slider and the second slide rail are combined by a sliding fit. The T-shaped piece is fixedly connected to the front side of the second slider, and the flexible clamping plate is fixedly attached to the surface of the T-shaped piece that is close to each other. This forms a linkage clamping structure that is driven by a single power source and can convert linear motion into synchronous centripetal motion, thereby achieving stable clamping of the workpiece.

[0009] Preferably, the structure of the cleaning mechanism is further optimized, including a second electric push rod, a servo motor, a base plate, an L-shaped plate, bolts, nuts, brushes, a retraction spring, and a connecting column. The fixed end of the second electric push rod is installed on the upper structure of the cleaning tank, and the movable end is fixedly connected to the servo motor. The base plate is fixedly connected to the housing of the servo motor, serving as an installation platform for the adjustment components. One end of the connecting column is fixedly connected to the output shaft of the servo motor, and the other end passes through the base plate and has brushes fixedly connected around it. This integrated design enables the cleaning mechanism to have comprehensive functions of lifting, rotating, and adaptive adjustment of brush head pressure.

[0010] Preferably, in order to achieve adaptive adjustment of the brush head pressure of the cleaning mechanism, an L-shaped plate is fixedly connected to the outside of the base plate, a bolt is slidably inserted through the L-shaped plate and fixedly connected to the brush, a nut is screwed into the bolt and abuts against the outer surface of the L-shaped plate, and a compression spring is fitted onto the bolt, with its two ends abutting against the base plate and the brush respectively. This allows for convenient adjustment of the brush's preload and enables the brush to adaptively conform to the inner wall of the housing with different inner diameters during operation.

[0011] Preferably, in order to ensure the smoothness and synchronicity of the clamping action, the first slide rail, the first slider, the V-shaped rotating plate, the second slide rail, the second slider, and the T-shaped piece in the fixing mechanism are all set in two groups and symmetrically distributed with the center vertical line of the hollow plate as the reference, so as to ensure that the clamping components on both sides can perform clamping or releasing actions synchronously and at the same speed.

[0012] Preferably, in order to improve cleaning efficiency and coverage, multiple brushes are provided and fixedly connected at even intervals along the circumference of the connecting column, so that the connecting column can perform a faster and more comprehensive scrubbing of the inner wall when rotating.

[0013] Preferably, it also includes a rinsing system consisting of a water pump and a nozzle. The outlet of the water pump is connected to the nozzle through a pipeline. The nozzle is fixed to the upper part of the cleaning tank and the nozzle faces the inner cavity of the workpiece to be cleaned. This is used to perform high-pressure water rinsing before or during mechanical brushing to improve the overall cleaning effect.

[0014] Preferably, in order to achieve reliable clamping while maximizing the protection of the workpiece, the flexible clamp is made of an elastic material such as rubber or polyurethane, which uses elastic deformation to buffer the clamping force and increase the contact area, thereby avoiding indentation or scratches on the outer surface of the motor housing.

[0015] Preferably, the cleaning mechanism can drive the servo motor and the brush connected to it to move up and down in the vertical direction through the extension and retraction of the second electric push rod, so that the brush head can accurately perform the actions of extending into the inner cavity of the workpiece for cleaning and withdrawing from the inner cavity of the workpiece, thereby realizing the automated control of the cleaning process.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem of poor versatility of existing clamping devices and easy damage to the outer wall when clamping workpieces of different specifications by setting up a fixing mechanism in which a V-shaped rotating plate driven by a first electric push rod is linked to a T-shaped piece with a flexible clamping plate for synchronous retraction.

[0018] 2. This utility model, by setting a brush assembly that is adjusted by nuts and bolts and pre-tightened by a contraction spring, enables the brush to adaptively extend and retract when rotated by a servo motor. This solves the problem of existing cleaning devices having fixed brush sizes, which cannot closely fit the inner walls of motor housings with different inner diameters, resulting in dead corners and poor cleaning effect.

[0019] 3. This utility model integrates an adaptive clamping mechanism with an adaptive cleaning mechanism that can be raised and rotated, and works in conjunction with a water pump and nozzle to solve the problems of low automation, cumbersome procedures and low cleaning efficiency in existing cleaning methods.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4 This utility model provides a motor housing inner wall cleaning device, which aims to solve the problems of poor versatility of existing clamping mechanisms and easy damage to workpieces, as well as the poor cleaning effect caused by the inability of the cleaning brush 305 to fit tightly against the inner wall of housings with different inner diameters.

[0029] like Figure 1 and Figure 2 As shown, the motor housing inner wall cleaning device includes a cleaning tank 1, a fixing mechanism 2 set above the cleaning tank 1, and a cleaning mechanism 3 set inside the cleaning tank 1. The cleaning tank 1 serves as the mounting base for the entire device and bears the workpiece and liquid during the cleaning process. The fixing mechanism 2 is used to quickly and stably clamp motor housings of different specifications. The cleaning mechanism 3 is used to adaptively lift and rotate the inner wall of the motor housing for cleaning.

[0030] Specifically, refer to Figure 1 , Figure 2 and Figure 3The fixing mechanism 2 includes a hollow plate 201, a first electric push rod 202, a first slide rail 203, a second slide rail 209, a first slider 204, a V-shaped rotating plate 205, a second slider 208, a T-shaped piece 207, and a flexible clamping plate 206. The first electric push rod 202 is installed inside the hollow plate 201 and provides the driving force for clamping and releasing actions. The first slide rail 203 is fixedly connected to the outer wall of the hollow plate 201 in the vertical direction, and the second slide rail 209 is fixedly connected to the lower part of the outer wall of the hollow plate 201 in the horizontal direction. The first slider 204 slides in cooperation with the first slide rail 203, and the rear part of the first slider 204 is connected to the pushing end of the first electric push rod 202, so that under the drive of the first electric push rod 202, it moves along the first slide rail 204. The slide rail 203 reciprocates up and down. The corner of the V-shaped rotating plate 205 is rotatably connected to the first slider 204 through a pin, so that the vertical movement of the first slider 204 can be converted into the swing of the V-shaped rotating plate 205. The second slider 208 is slidably engaged with the second slide rail 209, and the second slider 208 is rotatably connected to the bottom two ends of the V-shaped rotating plate 205 through a pin. When the V-shaped rotating plate 205 swings, it drives the second slider 208 to synchronously contract inward or expand outward along the second slide rail 209. The T-shaped piece 207 is fixedly connected to the front side of the second slider 208 as the execution end for directly clamping the workpiece. The flexible clamping plate 206 is fixedly attached to the side surface of the T-shaped piece 207 that is close to each other, so as to directly contact the outer wall of the motor housing when clamping.

[0031] Please refer to Figure 1 , Figure 2 and Figure 4 The driving part of the cleaning mechanism 3 consists of a second electric push rod 308 and a servo motor 307. The fixed end of the second electric push rod 308 is installed on the upper structure of the cleaning tank 1, and the movable end is fixedly connected to the servo motor 307. Through the extension and retraction of the second electric push rod 308, the entire servo motor 307 and the subsequent brushing components can be driven to rise and fall precisely in the vertical direction, so that the brush 305 can accurately extend into or exit from the motor housing to be cleaned. The bottom of the housing of the servo motor 307 is fixedly connected to a base plate 301, which serves as the installation platform for the entire brushing and adjustment subsystem. The output shaft of the servo motor 307 passes through the base plate 301 and is fixedly connected to one end of the connecting column 309. The rotational motion of the servo motor 307 is transmitted to the brush 305 through the connecting column 309, realizing high-speed rotational scrubbing of the inner wall.

[0032] The adaptive adjustment part of the cleaning mechanism 3 mainly consists of an L-shaped plate 303, a bolt 306, a nut 304, a retraction spring 302, and a brush 305. The L-shaped plate 303 is fixedly connected to the outside of the base plate 301. The bolt 306 is slidably inserted through the L-shaped plate 303, with one end fixedly connected to the brush holder of the brush 305 and the other end protruding from the L-shaped plate 303. The nut 304 is threaded into the part of the bolt 306 that protrudes from the L-shaped plate 303, and the end face of the nut 304 can abut against the outside of the L-shaped plate 303. On the surface, the compression spring 302 is fitted onto the bolt 306 in a compressed state, with its two ends abutting against the lower surface of the base plate 301 and the upper surface of the brush holder 305, respectively. This structure allows the initial extension position of the bolt 306 to be changed by rotating the nut 304, thereby adjusting the preload of the compression spring 302. This enables the brush 305 to adaptively contract or expand during the rotation cleaning process by relying on the elastic force of the compression spring 302, so as to always maintain a tight fit with the inner wall of the motor housing with different inner diameters.

[0033] As a preferred embodiment, in order to achieve smooth and synchronous clamping action, the clamping transmission part of the fixing mechanism 2 adopts a symmetrical layout, referring to... Figure 3 The first slide rail 203, the first slider 204, the V-shaped rotating plate 205, the second slide rail 209, the second slider 208, and the T-shaped piece 207 are all set in two groups. These two groups of structures are symmetrically distributed on both sides with the central vertical line of the hollow plate 201 as the reference. When the first electric push rod 202 is activated, it can ensure that the T-shaped pieces 207 and the flexible clamping plate 206 on both sides perform synchronous clamping or loosening actions with the same speed and displacement, thus ensuring the stability and centering of the motor housing.

[0034] As another preferred embodiment, to enhance the cleaning coverage and efficiency of the inner wall of the workpiece, the cleaning mechanism 3 has multiple brushes 305, as shown in the reference. Figure 4 Multiple brushes 305 are fixedly connected at even intervals along the circumference of the connecting column 309. When the servo motor 307 drives the connecting column 309 to rotate at high speed, the multiple brushes 305 can simultaneously scrub different areas of the inner wall, thereby significantly improving cleaning efficiency and ensuring that no area is missed.

[0035] As a preferred embodiment, it also includes a rinsing system, which consists of a water pump 4 and a spray nozzle 5, as shown in the reference. Figure 1 and Figure 2 The outlet of the water pump 4 is connected to the nozzle 5 through a pipeline. The nozzle 5 is fixed to the upper part of the cleaning tank 1, and the nozzle faces the inner cavity of the workpiece to be cleaned below the fixing mechanism 2. The water pump 4 pressurizes the external water source or the cleaning liquid in the cleaning tank 1 and sprays it out through the nozzle 5 to pre-rinse and assist rinsing the inner wall of the motor housing.

[0036] In a preferred embodiment, in order to effectively protect the surface from scratches or pressure damage while clamping the workpiece, the flexible clamping plate 206 is made of an elastic material such as rubber or polyurethane. This material has good elasticity and coefficient of friction. During the clamping process, the flexible clamping plate 206 can undergo slight elastic deformation to adapt to the small unevenness of motor housings or surfaces of different outer diameters, thereby achieving flexible and non-destructive clamping.

[0037] Working principle: When performing clamping operations, the first electric push rod 202 is activated, and the pushing end extends, pushing the first slider 204, which is connected to the transmission, to slide upward along the first slide rail 203. Since the corner of the V-shaped rotating plate 205 is rotatably connected to the first slider 204, the upward movement of the first slider 204 lifts the V-shaped rotating plate 205 upward. At the same time, since the bottom two ends of the V-shaped rotating plate 205 are rotatably connected to the second slider 208 respectively, this swinging action of the V-shaped rotating plate 205 will pull the two second sliders 208 to slide and retract towards each other along the second slide rail 209. The T-shaped piece 207 fixed to the front side of the second slider 208 and the flexible clamping plate 206 attached to the T-shaped piece 207 move inward synchronously, thereby clamping and fixing the motor housing to be cleaned. During this process, the elastic deformation ability of the flexible clamping plate 206 enables the flexible clamping plate 206 to adaptively clamp motor housings of different outer diameters and protect the surface of the motor housing.

[0038] During the cleaning operation, the water pump 4 is first started, and water is delivered to the nozzle 5 through the pipeline to initially rinse the inner wall of the motor housing. The operator can adjust the initial radial position of the brush 305 and set the preload of the contraction spring 302 by rotating the nut 304 to make the bolt 306 slide in the L-shaped plate 303. Then, the second electric push rod 308 is started, and the movable end retracts, driving the servo motor 307, the base plate 301 and the entire brushing assembly to descend vertically, so that the brush 305 is fully inserted into the motor housing. Finally, the servo motor 307 is started, and the output shaft drives multiple brushes 305 to rotate at high speed through the connecting column 309. During the rotation, the brushes 305 automatically open by the elastic force of the contraction spring 302 and closely adhere to the inner wall of the motor housing for scrubbing. Through this synergistic effect, this utility model solves the problems of poor versatility and poor cleaning effect of existing devices.
