Description

Technical Field

[0001] This utility model belongs to the field of processing technology for water-cooled motor housings of new energy vehicles, specifically a processing and finishing device for the production of water-cooled motor housings of new energy vehicles. Background Technology

[0002] As new energy vehicles develop towards higher power and higher integration, the heat dissipation performance of the drive motor directly determines the vehicle's power output and safety stability. Water cooling has become the mainstream solution due to its high efficiency. The water-cooled motor housing, as a core component for heat dissipation, requires the machining of complex cooling channels. The unobstructedness and sealing of these channels play a decisive role in the coolant circulation efficiency. During the housing manufacturing process, milling, grinding, and deburring processes are required to precisely machine the housing end faces, flange connection surfaces, and cooling channel opening edges to meet assembly tolerances and sealing requirements. Therefore, quality control of the machining and finishing processes is a crucial step in ensuring the housing's performance. Currently, the processing and finishing devices for water-cooled motor housings mainly rely on traditional metal processing equipment. After positioning the housing with tooling fixtures, the surface is finished by cutting or grinding mechanisms. However, since the cooling channel openings are often directly adjacent to the finishing processing area (such as the flange end face and the housing mating surface), metal shavings (such as aluminum shavings and iron shavings) generated during the finishing process can easily fall into the interior through the channel openings. There is a lack of cleaning structures for residual shavings inside the channels, resulting in the long-term problem of shavings retention. Debris residue in the cooling channel can cause multiple serious problems: First, debris accumulation can block the channel cross-section, increase the flow resistance of the coolant, reduce heat dissipation efficiency, cause the motor operating temperature to exceed the standard, and thus reduce power performance and shorten the motor life; Second, when the motor is running, the debris will wear down the inner wall of the channel as it flows with the coolant, damage the sealing structure, and cause the risk of coolant leakage.

[0003] Therefore, a processing and finishing device for the production of water-cooled motor housings for new energy vehicles is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a processing and trimming device for the production of water-cooled motor housings for new energy vehicles. This device is capable of performing channel debris removal during the trimming process of the water-cooled motor housing, preventing a large amount of debris from accumulating in the water-cooling channels, which would increase the flow resistance of the coolant, reduce heat dissipation efficiency, and greatly improve the service life of the water-cooled motor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a processing and trimming device for producing water-cooled motor housings for new energy vehicles, comprising a trimming table and a trimming mechanism installed on the surface of the trimming table; The surface of the trimming table is equipped with a cooling channel processing assembly, which includes connecting plates symmetrically arranged on the surface of the trimming table, a debris collection channel installed on one side of one of the connecting plates, a ventilation disc for debris processing, an air pump body, a debris collection cylinder, and an air outlet. The surface of the trimming table is equipped with a drive assembly, which includes a limiting plate symmetrically mounted on the surface of the connecting plate, a drive plate mounted on the bottom surface of the connecting plate, and a bidirectional lead screw, a drive motor, and a sensor for driving.

[0006] Preferably, the ventilation disc is installed on one side surface of one of the connecting plates, the air pump body is installed on the other side surface of the connecting plate, and the air outlet end of the air pump body is connected to the ventilation disc. A plurality of air outlet holes are evenly distributed on the surface of the ventilation disc. The debris collection cylinder is disposed on the other side surface of one of the connecting plates and is connected to the debris collection channel.

[0007] Preferably, the connection end between the debris collection cylinder and the debris collection channel is a conical structure, and its large end is detachably connected to the connecting plate by bolts.

[0008] Preferably, the contact surface of the ventilation disc is fitted with an elastic rubber pad.

[0009] Preferably, the limiting plate is slidably connected in the limiting groove opened on the surface of the dressing table, and the two ends of the bidirectional lead screw are respectively threaded to the two drive plates, and both ends of the bidirectional lead screw pass through the drive plates and are rotatably connected to the bottom surface of the dressing table.

[0010] Preferably, the drive motor is mounted on one side surface of the dressing table, and the output end of the drive motor passes through the dressing table and is connected to one end of the bidirectional lead screw.

[0011] Preferably, the sensor is installed at the air outlet of the ventilation disc and is electrically connected to a controller mounted on the surface of the trimming table via a transmission line, and the drive motor is electrically connected to this controller.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a cooling channel processing component, achieves the function of directional cleaning of debris after repair through the coordinated action of the debris collection channel, ventilation disc, and air pump body, avoiding debris accumulation in the cooling channel, ensuring the smooth flow of the cooling channel, avoiding the risk of subsequent motor heat dissipation failure, and facilitating the collection and processing of debris for unified cleaning or replacement.

[0013] 2. This utility model incorporates a drive assembly, which, through a bidirectional lead screw, drive motor, and sensor, enables precise docking between the cooling channel processing component and the housing.

Detailed Implementation

[0016] 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.

[0017] like Figures 1 to 5 As shown, this utility model provides a processing and trimming device for the production of water-cooled motor housings for new energy vehicles, including a trimming table 1 and a trimming mechanism 12 installed on the surface of the trimming table 1. A cooling channel processing assembly 2 is installed on the surface of the trimming table 1. The cooling channel processing assembly 2 includes connecting plates 21 symmetrically arranged on the surface of the trimming table 1, a debris collection channel 22 installed on one side of one of the connecting plates 21, a ventilation disc 23 for debris processing, an air pump body 24, a debris collection cylinder 25, and an air outlet 26. A ventilation disc 23 is installed on one side of another connecting plate 21, and an air pump body 24 is installed on the other side of this connecting plate 21. The air outlet of the air pump body 24 is connected to the ventilation disc 23. Multiple air outlets 26 are evenly distributed on the surface of the ventilation disc 23. A debris collection cylinder 25 is set on the other side of one of the connecting plates 21 and is connected to the debris collection channel 22. Through the collaboration of the debris collection channel 22, the ventilation disc 23, and the air pump body 24, the function of directional cleaning of debris after trimming is realized, avoiding debris from accumulating in the cooling channel, ensuring the smooth flow of the cooling channel, avoiding the risk of subsequent motor heat dissipation failure, and facilitating the collection and processing of debris for unified cleaning or replacement.

[0018] The connection end between the debris collection cylinder 25 and the debris collection channel 22 is set in a conical structure, and its large end is detachably connected to the connecting plate 21 by bolts. The cone-shaped large end chip inlet design can expand the chip inlet diameter, avoid the accumulation and blockage of small chips at the channel inlet, ensure the smooth flow of airflow and chips, and prevent chips from running out of the channel.

[0019] The contact surface of the ventilation disc 23 is equipped with an elastic rubber pad. The elastic rubber pad can deform when the ventilation disc 23 is in contact with the housing, filling the tiny gap between the two contact surfaces, preventing high-pressure airflow from leaking out of the gap, ensuring that all airflow enters the cooling channel, and guaranteeing cleaning pressure.

[0020] The surface of the trimming table 1 is equipped with a drive assembly 3. The drive assembly 3 includes a limiting plate 31 symmetrically mounted on the surface of the connecting plate 21, a drive plate 32 mounted on the bottom surface of the connecting plate 21, a bidirectional lead screw 33 for driving, a drive motor 34, and a sensor 35. The limiting plate 31 is slidably connected in the limiting groove opened on the surface of the trimming table 1. The two ends of the bidirectional lead screw 33 are respectively threaded to the two drive plates 32, and both ends of the bidirectional lead screw 33 pass through the drive plates 32 and are rotatably connected to the bottom surface of the trimming table 1. The cooling channel processing component 2 can be driven to accurately dock with the housing through the bidirectional lead screw 33, drive motor 34, and sensor 35, ensuring that the cleaning structure is aligned with the opening of the cooling channel, avoiding airflow leakage or debris leakage during cleaning, and maintaining docking accuracy for a long time.

[0021] The drive motor 34 is mounted on one side surface of the dressing table 1, and the output end of the drive motor 34 passes through the dressing table 1 and is connected to one end of the bidirectional lead screw 33. The drive motor 34 is mounted on one side surface of the dressing table 1, and the output end directly passes through the dressing table 1 and is connected to the bidirectional lead screw 33. The direct drive method is adopted, which improves the power transmission efficiency.

[0022] Sensor 35 is installed at the air outlet of ventilation disc 23 and is electrically connected to a controller mounted on the surface of trimming table 1 via a transmission line. Drive motor 34 is electrically connected to this controller, thereby enabling monitoring of whether it is in contact with the housing without manual intervention, reducing the labor intensity of operators.

[0023] Among them, the structure such as trimming mechanism 12, drive motor 34 and sensor 35 are existing technologies, and their working principles are known technologies. The appropriate model should be selected according to the actual use. Detailed operating steps can be referred to the publicly available technology. Sensor 35 can preferably be a differential pressure transmitter or a gauge pressure sensor; The dressing mechanism 12 includes a cutting tool, a spindle assembly, a feed drive module, and other structural components. The cutting tool can be a milling cutter / grinding wheel, a face milling cutter / disc milling cutter, or a special deburring tool. The core function of the spindle assembly is to drive the cutting tool to rotate at high speed and provide cutting power. The core function of the feed drive module is to control the spindle (and tool) to move at a preset speed, ensuring accurate cutting depth and path.

[0024] Working principle and process: The water-cooled motor housing of the new energy vehicle to be processed is hoisted onto the surface of the trimming table 1, and then processed and trimmed by the trimming mechanism 12. After the trimming mechanism 12 completes the trimming and resets, the controller receives the trimming completion signal and starts the drive assembly 3: the output end of the drive motor 34 drives the bidirectional lead screw 33 to rotate. Since the two ends of the bidirectional lead screw 33 are threadedly connected to the two drive plates 32, and the drive plates 32 are fixed to the connecting plate 21, when the bidirectional lead screw 33 rotates, it drives the two connecting plates 21 to move relative to each other along the surface of the trimming table 1. The limiting plate 31 slides synchronously along the limiting groove on the surface of the trimming table 1 to ensure the stability of the moving trajectory of the connecting plate 21. When the elastic rubber pad on the surface of the ventilation disc 23 of one side of the connecting plate 21 is completely in contact with the cooling channel opening on one side of the housing (achieving a seal and blocking debris from entering the channel), and the debris collection channel 22 of the other side of the connecting plate 21 is precisely aligned with the cooling channel opening on the other side of the housing, the sensor 35 at the air outlet of the ventilation disc 23 detects the sealing signal and feeds it back to the controller through the transmission line. The controller immediately stops the drive motor 34 to complete the sealing docking of the cooling channel processing component 2 with the housing. After docking, the controller automatically starts the air pump body 24: the high-pressure airflow generated by the air pump body 24 is delivered to the ventilation plate 23 through the air outlet end, and forms a multi-directional airflow through the air outlet holes 26 evenly distributed on the surface of the ventilation plate 23, pushing the debris near the opening of the cooling channel along the inside of the channel to the debris collection channel 22; since the connection end between the debris collection channel 22 and the debris collection cylinder 25 is a conical structure to expand the air inlet diameter, debris blockage is avoided, and all debris carried by the airflow falls into the debris collection cylinder 25 through the debris collection channel 22. After the air blowing cleaning is completed, the controller first shuts off the air pump body 24, and then controls the drive motor 34 to rotate in the opposite direction, driving the two connecting plates 21 to reset to both sides of the finishing table 1; the operator removes the fixed housing, checks the unobstructed cooling channel, and then moves to the next process; finally, by disassembling the bolts connecting the debris collection cylinder 25 to the connecting plate 21, the debris collection cylinder 25 is removed and the internal debris is poured out. After cleaning, the debris collection cylinder 25 is reinstalled, and the device returns to the ready-to-process state.
