Description

Technical Field

[0001] The present invention belongs to the technical field of motor casing cleaning, and in particular, relates to a motor casing cleaning device and a use method. Background Art

[0002] During the machining process of motor casings, multiple bowl-shaped plug holes are machined into the outer wall of the water channel. These bowl-shaped plug holes connect to the motor casing water channel, which can lead to aluminum chips being trapped within the motor casing water channel. Due to the spiral structure of the internal water channel, aluminum chips can easily become lodged within the channel. Therefore, the water channel must be cleaned before the bowl-shaped plug is press-fitted into the motor casing. Traditional high-pressure water washing or spray cleaning methods, with their single flow direction, cannot fully cover every corner and recessed area of ​​the spiral water channel. The spiral structure causes the water flow to lose kinetic energy at bends, and aluminum chips easily adhere to the outer edges of the bends due to centrifugal force, making conventional flushing ineffective. To compensate for this lack of coverage, extended cleaning times or repeated cleaning cycles may be necessary, resulting in increased production cycle times. The complex spatial trajectory of the spiral water channel makes it difficult for traditional automated cleaning equipment (such as robotic spraying) to accurately plan the cleaning path. This can lead to missed cleaning spots, necessitating manual re-cleaning, reducing the continuity of the automated production line and resulting in low cleaning efficiency. Manual cleaning of the spiral water channel with a brush or other slender tool can easily scratch the inner wall if not handled properly, resulting in excessive surface roughness, affecting the seal between the bowl plug and the water channel, and even causing leakage under the impact of high-pressure water flow. Even manual cleaning only ensures a clean effect on the exterior of the motor housing, but it is difficult to ensure a clean effect inside the water channel, resulting in aluminum chips remaining in the water channel. Summary of the Invention

[0003] The object of the present invention is to provide a motor casing cleaning device and a method for using the same, which controls the motor to drive the motor casing to rotate to a preset angle, and the sealing unit seals the vertically upward bowl-shaped plug hole, and the high-pressure water flow is injected into the bowl-shaped plug hole through the cleaning water inlet pipe provided on the sealing block, and the water channel of the motor casing is cleaned by the pressure of the water flow and the action of gravity, and the aluminum chips are flushed out from the unblocked bowl-shaped plug holes at other positions and the water channel outlets of the motor casing water channel; the unblocked bowl-shaped plug holes at other positions of the motor casing solve the problem of single water flow direction in traditional cleaning methods, so that the flow direction of the high-pressure water flow can completely cover every corner and inner wall depression of the motor casing water channel, avoiding the attenuation of kinetic energy of the high-pressure water flow, and the aluminum chips are flushed out from the nearest bowl-shaped plug hole or the water channel outlet of the motor casing water channel by the high-pressure water flow, which greatly improves the cleaning effect and improves the cleaning efficiency. The cleaning device can also effectively clean the appearance of the motor casing, is simple to operate, and saves time and effort.

[0004] The specific plan is as follows:

[0005] A motor casing cleaning device comprises a frame, a cleaning chamber, a positioning unit, a rotating unit and a blocking unit. The cleaning chamber is arranged on the upper part of the frame. The positioning unit is arranged in the cleaning chamber, and comprises a fixed base plate and a motor casing positioning block assembly. The motor casing positioning block assembly is fixed on the fixed base plate. The fixed base plate is parallel to and adjacent to the rear side wall of the cleaning chamber. The rotating unit comprises a motor and a connecting shaft. The motor is fixed on the outer wall of the rear side wall of the cleaning chamber. The connecting shaft horizontally penetrates into the rear side wall of the cleaning chamber and its two ends are respectively transmission-connected to the motor shaft and the fixed base plate. The blocking unit comprises a vertical telescopic mechanism and a bowl-shaped plug hole blocking block. The vertical telescopic mechanism is arranged outside the top of the cleaning chamber, and its telescopic end vertically penetrates into the cleaning chamber and is fixedly connected to the bowl-shaped plug hole blocking block. The bowl-shaped plug hole blocking block is provided with a vertically penetrating cleaning water inlet pipe, and the upper end pipe mouth of the cleaning water inlet pipe is the cleaning water inlet.

[0006] The motor casing cleaning device of the present invention has a cleaning chamber fixedly mounted on the upper portion of the frame. A closable chamber door is provided on the front opening of the cleaning chamber. Closing the chamber door before cleaning the motor casing forms a relatively enclosed space, thereby preventing splashing of cleaning water and aluminum chips during cleaning. The chamber door opening and closing structure of the present invention is preferably a telescopic cylinder mechanism. The chamber door is mounted on the telescopic cylinder mechanism, which is mounted on the outer end surface of the cleaning chamber top plate, enabling the chamber door to slide vertically open and close on the front opening of the cleaning chamber. The positioning unit is installed within the cleaning chamber. The fixed baseplate of the positioning unit is equipped with a motor housing positioning block assembly. This block assembly includes an inner cavity positioning block and two outer contour positioning blocks. The inner cavity positioning block is shaped to match the motor housing's inner cavity and is bolted to the middle of the front sidewall of the fixed baseplate. Before cleaning, the motor housing is fitted over the inner cavity positioning block to radially secure the motor housing. The inner rings of the two outer contour positioning blocks are shaped to match the outer contour of the motor housing. The two outer contour positioning blocks are bolted to the front sidewall of the fixed baseplate, symmetrically spaced on either side of the inner cavity positioning block. Once the motor housing is fitted over the inner cavity positioning block, the two outer contour positioning blocks tightly adhere to the outer contour of the motor housing, securing the motor housing axially. A flange is bolted to the rear sidewall of the fixed baseplate. The fixed baseplate is positioned horizontally within the cleaning chamber to ensure the motor housing is laterally secured within the chamber during cleaning. The motor mounting bracket of the rotation unit is secured to the outer wall of the rear sidewall of the cleaning chamber, and the motor is fixed to the motor mounting bracket. A through-hole is provided in the rear wall of the cleaning chamber, and a connecting rod is mounted horizontally. One end of the rod is connected to the motor shaft, while the other end passes through the through-hole in the rear wall and is fixedly connected to the center hole of the flange. Rotation of the motor drives the connecting rod, which in turn rotates the fixed baseplate, which is secured to the flange and connecting rod, around the motor shaft, causing the motor housing, fixed to the fixed baseplate, to rotate 360 ​​degrees around the motor shaft.

[0007] The motor casings suitable for cleaning with the cleaning device of the present invention are generally those with multiple groups of bowl-shaped plug holes spaced along the same circumference of the outer wall of the motor casing waterway. The multiple groups of bowl-shaped plug holes are concentric with the circumference of the motor casing cavity, and each group of cleaning bowl-shaped plug holes is arranged in pairs, side by side. Although the bowl-shaped plug hole sealing block structure of the present invention preferably has a sealing port structure with two sealing portions and two cleaning water inlet pipes, this does not mean that the present invention abandons protection for other different bowl-shaped plug hole sealing block structures. In a few motor casings, the bowl-shaped plug holes are not arranged in pairs, but are arranged in a row of three on the same circumference. The structure of the bowl-shaped plug hole sealing block can be modified according to actual needs, and these modified sealing block structures also fall within the technical solutions of the present invention. The preferred bowl-shaped plug hole sealing block structure of the present invention has two sealing portions and two vertically extending cleaning water inlet pipes. The two sealing portions respectively block the corresponding bowl-shaped plug holes. After blocking, the two cleaning water pipes are inserted into the corresponding bowl-shaped plug holes and connected to the motor casing waterway. Multiple groups of bowl-shaped plug holes are arranged at intervals, and the motor housing is driven by the motor to rotate in a circumferential direction. When the motor rotates to a certain angle, it can rotate one group of bowl-shaped plug holes to a vertical upward direction. The vertical telescopic mechanism of the plugging unit is fixedly installed on the outer end surface of the top plate of the cleaning chamber to prevent it from being splashed by cleaning water. A through hole is provided in the top plate of the cleaning chamber, and the telescopic end of the vertical telescopic mechanism vertically penetrates the through hole. Its lower end is fixedly connected to the top surface of the bowl-shaped plug hole blocking block in the cleaning chamber. The bowl-shaped plug hole blocking block is equipped with a through-going cleaning water inlet pipe, and the bowl-shaped plug hole blocking block can rise or fall with the telescopic end of the vertical telescopic mechanism. The bowl-shaped plug hole sealing block is located directly above the vertically upward bowl-shaped plug hole. When cleaning the motor casing, the telescopic end of the vertical telescopic mechanism extends downward until the bowl-shaped plug hole sealing block completely blocks the bowl-shaped plug hole. The upper end of the cleaning water inlet pipe is fixedly connected to the outlet pipe of the high-pressure water pump of the clean water tank through the water pipe, and the lower end of the cleaning water inlet pipe enters the bowl-shaped plug hole and is connected to the water channel of the motor casing. During cleaning, high-pressure water flows from the cleaning water inlet pipe into the blocked bowl-shaped plug hole and then flows into the water channel of the motor casing. With the help of water pressure and gravity, the aluminum chips in the water channel of the motor casing are flushed out from other unblocked bowl-shaped plug holes or the water channel outlets of the motor casing water channel.

[0008] The motor housing waterway has a spiral structure. In traditional cleaning methods, the high-pressure water flow has a single direction. However, the present invention secures the motor housing horizontally within the cleaning chamber, with the blocked bowl-shaped plug hole pointing vertically upward. Other sets of bowl-shaped plug holes spaced circumferentially within the motor housing are unblocked. Combined with the two waterway openings within the motor housing, this changes the direction of the water flow, allowing the high-pressure water flow to fully cover the entire motor housing waterway, preventing kinetic energy attenuation. The high-pressure water flow flushes aluminum chips from the motor housing waterway through the nearest bowl-shaped plug hole or waterway opening, significantly improving cleaning effectiveness and efficiency.

[0009] The motor casing cleaning device of the present invention also includes a cleaning unit. The cleaning unit's clean water tank and high-pressure water pump are connected via a water pipe. A water inlet hole is provided on the side wall of the cleaning chamber. The high-pressure water pump's discharge port is fixedly connected to the upper end of the cleaning water inlet pipe via a water pipe inserted through the water inlet hole. During cleaning, the high-pressure water pump is activated, and high-pressure water flows from the cleaning water inlet pipe into the blocked bowl-shaped plug hole, cleaning the motor casing's water channel.

[0010] The present invention also includes a sewage discharge unit. The cleaned sewage cannot be discharged directly into the surrounding environment, so a sewage discharge unit is required. The filter water tank of the sewage discharge unit is fixedly installed at the lower part of the frame, and a sewage outlet is provided on the bottom plate of the cleaning chamber. The two ends of the sewage pipe are fixedly connected to the filter water tank and the sewage outlet respectively. The flushed sewage and aluminum chips flow from the sewage outlet into the filter water tank during cleaning. A filter device can also be installed in the filter water tank. The filter device is fixed on the upper part of the filter water tank. The lower end of the sewage pipe is connected to the filter device, and the filtered sewage flows into the filter water tank. After cleaning, subsequent treatment is carried out.

[0011] Furthermore, the positioning unit also includes a flange, which is screwed and fixed to the rear side wall of the fixed base plate, and one end of the connecting shaft that penetrates into the cleaning chamber is fixed to the center hole of the flange. The flange is adjacent to the rear side wall of the cleaning chamber. The motor housing positioning block assembly includes an inner cavity positioning block and two outer contour positioning blocks. The inner cavity positioning block is fixed to the middle of the front side wall of the fixed base plate, and the two outer contour positioning blocks are symmetrically fixed on the front side wall of the fixed base plate on both sides of the inner cavity positioning block.

[0012] The inner cavity positioning block and two outer contour positioning blocks fixed by bolts on the front side wall of the fixed base plate are used to fix the motor housing in the radial and axial directions during cleaning. A flange is bolted on the rear side wall of the base plate. One end of the connecting shaft of the rotating unit is connected to the motor shaft, and the other end penetrates into the rear side wall of the cleaning chamber and is fixed in the center hole of the flange, so that the motor housing can rotate around the rotating motor shaft.

[0013] Furthermore, the rotating unit also includes a motor fixing bracket, the motor is fixedly connected to the motor fixing bracket, and the motor fixing bracket is fixed to the outer wall of the rear side wall of the cleaning chamber.

[0014] The motor mounting bracket is fixedly mounted on the rear outer wall of the cleaning chamber. A horizontal connecting rod, one end of which drives the motor shaft, is inserted into a through-hole in the corresponding rear wall. The other end of the connecting rod passes through the through-hole and securely connects with the center hole of the positioning unit's flange. The motor drives the connecting rod, flange, fixed baseplate, and motor housing fixed to the fixed baseplate to rotate circumferentially around the motor shaft. By controlling the motor's rotation angle, the bowl-shaped plug holes can be sealed and cleaned in groups. The motor rotates 360 degrees to complete the cleaning of all bowl-shaped plug holes.

[0015] Furthermore, the vertical telescopic mechanism includes a cylinder fixing frame and a sealing cylinder. The cylinder fixing frame is fixedly connected to the outer end surface of the top plate of the cleaning chamber, and the sealing cylinder is fixedly connected to the cylinder fixing frame. The piston rod of the sealing cylinder vertically penetrates into the top plate of the cleaning chamber and its lower end is fixedly connected to the bowl-shaped plug hole sealing block.

[0016] The vertical extension and retraction mechanism of the plugging unit is preferably a telescopic cylinder. A cylinder mounting bracket is mounted on the outer end surface of the cleaning chamber's top plate, and the plugging cylinder is fixedly mounted on the mounting bracket. The piston rod of the plugging cylinder vertically extends downward through a through-hole in the top plate, with its lower end fixedly connected to the upper end surface of the bowl-shaped plugging block. During cleaning, the piston rod drives the bowl-shaped plugging block to vertically raise and lower the block, thereby sealing or releasing the bowl-shaped plugging hole.

[0017] Furthermore, the cleaning chamber includes an openable and closable chamber door and a telescopic cylinder mechanism. The chamber door is arranged on the telescopic cylinder mechanism. The telescopic cylinder mechanism is arranged on the outer end surface of the top plate of the cleaning chamber. The chamber door can be vertically telescopically slid to open and close on the front end opening of the cleaning chamber.

[0018] The door of the cleaning chamber is an openable and closable door. The invention preferably uses a telescopic cylinder mechanism to realize the vertical sliding opening and closing of the door.

[0019] Furthermore, the cleaning unit includes a clean water tank and a high-pressure water pump. The clean water tank is arranged on one side of the frame. The clean water tank and the high-pressure water pump are connected by a water pipe. A water inlet hole is provided on the side wall of the cleaning chamber. The water outlet of the high-pressure water pump and the upper end of the cleaning water inlet pipe are fixedly connected by a water pipe inserted into the water inlet hole.

[0020] When cleaning the motor housing, high-pressure water is injected into the bowl-shaped plug hole and the motor housing water channel. The cleaning unit's high-pressure water pump draws water from the clean water tank through a water pipe, pressurizes it, and injects it into the cleaning water inlet pipe to clean the motor housing water channel or the motor housing exterior. The cleaning liquid used during cleaning should be selected according to actual needs.

[0021] Furthermore, it also includes a sewage discharge unit, which is arranged at the lower part of the frame. The sewage discharge unit includes a filtered water tank and a filtering device. A sewage outlet is provided on the bottom plate of the cleaning bin. The filtered water tank and the filtering device are fixedly connected to the bottom of the cleaning bin. The filtering device is connected to the sewage outlet through a pipeline, and the filtering device is connected to the filtered water tank through a pipeline.

[0022] The sewage after cleaning contains aluminum chips and other substances and cannot be discharged at will. Therefore, a filtering device is fixedly installed at the bottom of the frame. The filtering device filters out the aluminum chips in the sewage, and the filtered water flows into the filter water tank through the pipeline for storage.

[0023] Furthermore, the sewage discharge unit also includes a filtered water circulation pump, which is connected to the filtered water tank and the clean water tank through pipelines.

[0024] The filtered water circulation pump is connected to the filtered water tank and the clean water tank through pipelines, and the filtered water is input into the clean water tank to realize the recycling of water and save cleaning costs.

[0025] A method for using a motor housing cleaning device, wherein the motor housing cleaning device is used to clean the motor housing before a bowl-shaped plug is press-fitted onto the motor housing, comprising the following steps:

[0026] S1. Place the motor housing on the fixed base plate, cover the inner cavity of the motor housing with the inner cavity positioning block, and fix the two outer contour positioning blocks to clamp the outer contour of the motor housing;

[0027] S2. After the motor housing cleaning device is started, the door of the cleaning chamber slides downward and closes, and the motor of the rotating unit rotates, which drives the motor housing to rotate until a group of bowl-shaped plug holes in the motor housing are vertically upward and located directly below the blocking block. The motor then stops rotating, controls the piston rod of the blocking cylinder to move downward, and the blocking block moves downward until the bowl-shaped plug holes are blocked and the lower end of the cleaning water inlet pipe is inserted into the bowl-shaped plug holes, and then stops;

[0028] S3. Turn on the high-pressure water pump of the clean water tank. After being pumped out, the high-pressure water flows along the cleaning water inlet pipe into the bowl-shaped plug hole and then into the water channel of the motor housing. The aluminum chips are flushed out from the unblocked bowl-shaped plug holes at other positions and the water channel openings of the motor housing by the high-pressure water flow. When no more aluminum chips are flushed out, the cleaning work of the bowl-shaped plug hole at one angle is completed;

[0029] S4. Turn on the filtered water circulation pump (8) to pump the filtered water in the filtered water tank (7.1) into the clean water tank for recycling.

[0030] S5, control the motor to rotate to the next angle, so that another group of bowl-shaped plug holes on the motor housing rotate to be vertically upward and located directly below the blocking block, and then the motor stops rotating. The blocking cylinder drives the blocking block to block the bowl-shaped plug holes directly below, so that the lower end of the clean water inlet pipe is inserted into the bowl-shaped plug hole, and then repeat steps S3 and S4 to clean this group of bowl-shaped plug holes; repeat the cleaning process multiple times until the motor rotates 360 degrees and all the bowl-shaped plug holes are cleaned.

[0031] S6. Control the sealing cylinder to rise vertically, and the sealing block rises upward accordingly. The lower end of the cleaning water inlet pipe is separated from the bowl-shaped plug hole. Control the high-pressure water pump of the clean water tank to start. High-pressure water flows continuously from the lower end of the cleaning water inlet pipe to the outer surface of the motor housing. Control the rotating unit to rotate clockwise, driving the motor housing to rotate clockwise for two weeks to clean the inner and outer surfaces of the motor housing; then control the motor to reverse, driving the motor housing to rotate counterclockwise for two weeks to clean the outer surface of the motor housing, thus completing the cleaning of the motor housing;

[0032] S7. Collect and clean the aluminum chips in the filter device.

[0033] Furthermore, the bowl-shaped plug hole sealing block includes two sealing parts and two cleaning water inlet pipes. The two sealing parts are arranged side by side at the lower part of the bowl-shaped plug hole sealing block and their shapes match the shapes of the corresponding bowl-shaped plug holes. The two cleaning water inlet pipes are arranged side by side on the bowl-shaped plug hole sealing block, and the lower end pipe openings of the two cleaning water inlet pipes are respectively opened at the bottom of the two sealing parts. After the two sealing parts and the corresponding bowl-shaped plug holes are fitted and sealed, the lower end pipe openings of the two cleaning water inlet pipes extend into the corresponding bowl-shaped plug holes and are connected with the water channel of the motor casing.

[0034] The motor housing cleaning device of the present invention is used to clean the motor housing, which can not only clean the motor housing water channel and bowl-shaped plug hole, but also clean the appearance of the motor housing. By controlling the rotation angle of the motor, a group of bowl-shaped plug holes are vertically upward and located directly below the blocking block. The bowl-shaped plug hole blocking block moves downward through the piston rod of the blocking cylinder until the group of bowl-shaped plug holes is blocked, so that the cleaning water inlet pipe is connected to the blocked bowl-shaped plug hole. High-pressure water is injected into the motor housing water channel connected to the bowl-shaped plug hole, and sewage and aluminum chips are flushed out from the water channel openings of other unblocked bowl-shaped plug holes and motor housing water channels, achieving the purpose of grouping and blocking and cleaning the bowl-shaped plug holes and motor housing water channels. After the motor rotates 360 degrees, all the bowl-shaped plug holes are cleaned. The piston rod of the blocking cylinder is controlled to rise. After the bowl-shaped plug hole blocking block moves upward and disengages from the bowl-shaped plug hole, the high-pressure water pump is started, injecting high-pressure water. The high-pressure water flows out from the lower end of the cleaning water inlet pipe to flush the appearance of the motor housing. At this time, the motor is controlled to rotate clockwise for two cycles to rinse the motor housing; the motor is controlled to reverse and rotate counterclockwise for two cycles to further rinse the motor housing, thereby completing the cleaning of the motor housing. The cleaning method of the present invention is simple, efficient, and labor-saving.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. The motor casing cleaning device of the present invention not only seals the bowl-shaped plug hole separately to clean the bowl-shaped plug hole and the motor casing water channel, but also effectively cleans the motor casing exterior. Its simple and compact structure improves cleaning efficiency and saves labor costs.

[0037] 2. The motor casing cleaning device of the present invention controls the motor to rotate to a preset angle so that a group of bowl-shaped plug holes are vertically upward and located directly below the blocking unit. The group of bowl-shaped plug holes are blocked by a vertical telescopic mechanism, and high-pressure water is injected into the bowl-shaped plug holes from the cleaning water inlet pipe. The water pressure and gravity are used to clean the water channel of the motor casing, and sewage and aluminum chips are flushed out from the unblocked bowl-shaped plug holes and the water channel outlets of the motor casing at other positions, thereby solving the problem of single water flow direction in traditional cleaning methods, and allowing the flow direction of high-pressure water to completely cover every corner and inner wall depression of the motor casing water channel, avoiding the attenuation of kinetic energy of the high-pressure water flow, and greatly improving the cleaning effect. The method of using the invented motor casing cleaning device is simple to operate and has high cleaning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
