Description

Technical Field

[0001] This invention relates to the field of new energy motor processing equipment, and in particular to a laser engraving machine for the inner wall of a new energy water-cooled motor housing. Background Technology

[0002] In the field of new energy motor manufacturing, water-cooled motors rely on the internal flow channels of the casing for heat dissipation and cooling. The casing of a new energy water-cooled motor with flange bosses mainly consists of a cylindrical body, flanges set at one or both ends, and connection holes on the flanges for mounting bolts. The flange bosses are usually used to improve connection rigidity and play a positioning role during assembly. The engraving process of its deep cavity inner wall directly determines the recognizability, assembly accuracy and surface quality of the finished product. However, the existing laser engraving technology inside the casing of new energy water-cooled motors still has many technical bottlenecks.

[0003] Existing traditional laser engraving equipment mostly adopts a single-function design. Before engraving, manual cleaning of oil stains and rust is required on the inner wall of the new energy water-cooled motor shell. This is not only labor-intensive but also results in incomplete cleaning. Residual impurities lead to uneven depth of engraved flow channels and reduced accuracy. Secondly, in terms of positioning and fixing, existing equipment generally relies on manual calibration of the shell position, which is difficult to accurately position, resulting in large axial positioning deviations. This leads to a mismatch between the engraved lines and product assembly requirements, causing problems such as seal slippage and assembly jamming. At the same time, the laser emission angle adjustment flexibility of existing engraving mechanisms is insufficient, making it difficult to achieve full-area engraving of the inner wall of the cylinder. For the inner wall of the long cylindrical new energy water-cooled motor shell, there are often engraving blind spots. Moreover, the smoke and waste generated during engraving cannot be discharged in time, which not only blocks the light path and affects the engraving accuracy but also causes wear on equipment components and increases subsequent cleaning costs. To solve the above problems, we propose a laser engraving machine for the inner wall of the new energy water-cooled motor shell. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This laser engraving machine for the inner wall of a new energy water-cooled motor housing, through a dual collaborative structure of inner support and sensor feedback positioning, completely solves the problems of large positioning errors and poor stability of traditional equipment. After the operator places the new energy water-cooled motor housing on the outside of the positioning column, the fixing mechanism is activated, driving multiple positioning plates to provide uniform support from the inside of the housing. Then, the positioning mechanism is activated, and the fourth electric telescopic rod pushes the first sleeve to move towards the housing port. When the first sleeve contacts the flange boss of the housing, it stops. When the boss is inserted into the flange boss hole as the housing rotates, the elastic component resets, completing the axial positioning and ensuring that the flow channel texture deep inside the new energy water-cooled motor housing is free of distortion and has consistent depth.

[0018] 2. This new energy water-cooled motor housing inner wall laser engraving machine, through the integrated layout of the cleaning and engraving mechanism, seamlessly connects the pre-treatment cleaning and laser engraving processes, eliminating the need for housing transfer. This solves the problems of cumbersome processes and secondary pollution associated with traditional equipment. After clamping and positioning, the third motor drives the fifth electric telescopic rod to adjust the angle of the directional plate. The electric slider moves along the electric slide groove, aligning the second sleeve with the housing port. The sixth electric telescopic rod pushes the second sleeve deep into the housing. The fourth motor drives the rotating column to rotate. The guide column rotates and moves up and down along the circular track via the first slider, driving the cleaning rod and cleaning strip to clean the inner wall impurities in all directions. Simultaneously, the air pump is started, and negative pressure is formed through the first leak and the first telescopic tube, sucking the waste residue into the collection box in real time. After cleaning, only the directional plate needs to be rotated by the third motor to switch to the engraving process of the third sleeve, eliminating the need for secondary positioning. This shortens the single processing cycle, and the engraving can be performed directly after cleaning, completely avoiding secondary pollution during the transfer process.

A fourth motor 49 is provided on the bottom sidewall of the second sleeve 48. A rotating column 412 is provided through the output end of the fourth motor 49 and passes through the second sleeve 48. A guide column 413 is slidably connected to the outer sidewall of the rotating column 412. A first slider 411 is provided on the outer sidewall of the guide column 413. The outer sidewall of the first slider 411 is slidably connected to the inner sidewall of the annular track 410. A cleaning rod 414 is provided on the top sidewall of the guide column 413. A cleaning strip 415 is provided on the outer sidewall of the cleaning rod 414. A first cover plate 416 is provided on the top sidewall of the second sleeve 48. Multiple first drain holes 417 are provided at the bottom of the inner sidewall of the first cover plate 416. A fixing box 418 is provided on the bottom side wall of the first cover plate 416. A first telescopic tube 419 is provided on the side wall of the fixing box 418. The telescopic ends of the other two sixth electric telescopic rods 47 are provided with third sleeves 423 through the guide plate 46. A second cover plate 424 is provided on the top side wall of the third sleeve 423. A fifth motor 425 is provided on the bottom side wall of the third sleeve 423. A rotating rod 426 is provided on the output end of the fifth motor 425 through the third sleeve 423. A fixing block 427 is provided on the outer side wall of the rotating rod 426. A sixth motor 428 is provided on one side wall of the fixing block 427. A rotating block 429 is provided on the output end of the sixth motor 428. The wall is equipped with a universal laser 430. Multiple second leakage holes 431 are opened at the bottom of the inner side wall of the second cover plate 424. A third sleeve 423 is provided at the bottom side wall of the second cover plate 424. A third telescopic tube 432 is provided on one side wall of the third sleeve 423. An air pump 420 is provided at the bottom side wall of the directional plate 43. The input end of the air pump 420 is fixedly connected to the other end of the first telescopic tube 419 and the third telescopic tube 432. The output end of the air pump 420 is provided with a second telescopic tube 421. A slag collection box 422 is provided on one side wall of the operating table 1. The other end of the second telescopic tube 421 is fixedly connected to the inside of the slag collection box 422. A drawer is detachably connected to one side wall of the slag collection box 422.

[0031] Specifically, the fifth electric telescopic rod 42 is activated and extends, causing the directional plate 43 to move vertically downwards, positioning the second sleeve 48 below the directional plate 43 below the port of the new energy water-cooled motor housing. Then, the third motor 41 is activated, its output shaft rotating the fifth electric telescopic rod 42 to adjust the horizontal angle of the directional plate 43. Next, the drive device of one set of electric slide rails 44 is activated, causing the electric slider 45 to slide horizontally along the inner wall of the electric slide rail 44, moving the guide plate 46 synchronously, aligning the top of the second sleeve 48 directly below the port of the new energy water-cooled motor housing, ensuring smooth insertion into the housing. Finally, one set of sixth electric telescopic rods 47 is activated, slowly extending and pushing the second... The sleeve 48 moves vertically upward, causing the sweeping rod 414 and sweeping strip 415 to gradually extend deep into the interior of the new energy water-cooled motor housing until the first cover plate 416 reaches the housing port. The sweeping rod 414 is completely within the preset cleaning area. Subsequently, the fourth motor 49 is started. The output shaft of the fourth motor 49 drives the rotating column 412 to rotate at high speed. The rotating column 412 is slidably connected to the guide column 413, causing the guide column 413 to rotate synchronously. At the same time, the first slider 411 on the outer side of the guide column 413 slides along the inner wall of the annular track 410, thereby causing the guide column 413 to move up and down and rotate along the annular track 410. The rotation of the guide column 413 drives the sweeping rod 414 and sweeping strip 415 to rotate synchronously. The sweeping strip 415 and the new energy water-cooled motor... The machine casing is in close contact with the inner wall, performing high-speed cleaning of oil stains, rust, dust, and other impurities on the inner wall, peeling the impurities off the inner wall. Simultaneously, the air pump 420 is activated, generating negative pressure, which is transmitted to the first cover plate 416 through the first telescopic tube 419 and the fixed box 418. Multiple first leakage holes 417 at the bottom of the inner side wall of the first cover plate 416 form a negative pressure suction port, sucking in the waste residue, dust, and other impurities generated during cleaning. These are then transported to the slag collection box 422 for collection through the first telescopic tube 419, the air pump 420, and the second telescopic tube 421. After cleaning is completed, the fourth motor 49 is turned off first. After the cleaning rod 414 stops rotating, the air pump 420 is turned off. Then, the sixth electric telescopic rod 47 is controlled to retract, causing the second sleeve 48 to slowly exit the new energy water-cooled system. The motor housing returns to its initial position. The third motor 41 is restarted, and its output shaft drives the fifth electric telescopic rod 42 to rotate. The adjusting guide plate 43 rotates 180 degrees. Then, the drive device of another set of electric slide rails 44 is activated. The electric slider 45 slides horizontally along the inner wall of the electric slide rail 44, driving another guide plate 46 to move synchronously, so that the top of the third sleeve 423 is aligned with the port directly below the new energy water-cooled motor housing. The sixth electric telescopic rod 47 is activated, and it slowly extends, pushing the third sleeve 423 to move vertically upward, so that the rotating rod 426 extends deep into the new energy water-cooled motor housing until the second cover plate 424 is in contact with the housing port. The omnidirectional laser 430 reaches the engraving starting position.In the control system's operating interface, a pre-designed engraving pattern is imported. Based on the material and engraving depth requirements of the new energy water-cooled motor's casing, the relevant parameters of the omnidirectional laser 430 are set. The laser beam is aligned with the starting point of the preset engraving path, and the omnidirectional laser 430 emits the laser beam. Simultaneously, the fifth motor 425 starts, driving the rotating rod 426, the fixed block 427, and the omnidirectional laser 430 to rotate at a uniform speed, achieving circumferential engraving coverage of the inner wall of the new energy water-cooled motor's casing. The sixth motor 428 is then activated, and its output shaft drives... The rotating block 429 swings, thereby adjusting the emission angle of the omnidirectional laser 430 to ensure that the laser beam covers the entire engraving area. Simultaneously, the air pump 420 is activated, generating negative pressure through the third telescopic tube 432, the third sleeve 423, and the second drain hole 431 on the second cover plate 424. This pressure promptly draws in the smoke and waste generated during the engraving process, transporting it through the third telescopic tube 432, the air pump 420, and the second telescopic tube 421 to the waste collection box 422. This prevents smoke and dust from obstructing the light path and affecting engraving accuracy, while also preventing waste from accumulating in the engraving area and causing secondary damage.

[0032] In this embodiment, the fixing mechanism 2 includes a mounting box 21 at the top of the chain conveyor belt 12. Lifting frames 22 are provided on both side walls of the mounting box 21. Each of the top side walls of the two lifting frames 22 is provided with a first electric telescopic rod 23. A movable block 24 is provided at the telescopic end of the first electric telescopic rod 23. The outer side wall of the movable block 24 is slidably connected to the inner side wall of the lifting frame 22. A second electric telescopic rod 25 is provided on one side wall of the movable block 24. A clamping plate 26 is provided through the telescopic end of the second electric telescopic rod 25 and extends through the movable block 24. A positioning post 27 is provided on the inner side wall of the mounting box 21. 7. Multiple third electric telescopic rods 28 are provided on the outer side wall. Each telescopic end of the multiple third electric telescopic rods 28 is provided with a positioning plate 29. The mounting box 21 has a first slot 210 inside. Two first gears 212 are rotatably connected to the inner side wall of the first slot 210. The two first gears 212 are connected to a transmission chain 211. A second motor 213 is provided at the bottom of the inner side wall of the mounting box 21. The output end of the second motor 213 is fixedly connected to the top of one first gear 212. The top of the other first gear 212 passes through the mounting box 21 and is fixedly connected to the bottom of the positioning post 27.

[0033] Specifically, the second motor 213 is started, and the output shaft of the second motor 213 drives a first gear 212 fixedly connected to it to rotate. Through the meshing transmission of the transmission chain 211, it drives another first gear 212 to rotate synchronously, thereby driving the positioning column 27 and the new energy water-cooled motor housing sleeved on it to rotate slowly.

[0034] In this embodiment, the positioning mechanism 3 includes two fixing frames 31 provided on the top side wall of the mounting box 21. A fourth electric telescopic rod 32 is provided on one side wall of the fixing frame 31. A first sleeve 33 is provided at the telescopic end of the fourth electric telescopic rod 32. A touch sensor 34 is provided on the inner side wall of the first sleeve 33. An elastic component 35 is provided on the inner side wall of the first sleeve 33. A protrusion 36 is provided at the other end of the elastic component 35.

[0035] Specifically, when the positioning mechanism 3 is activated, the fourth electric telescopic rods 32 on the two fixed frames 31 are simultaneously activated and extended, pushing the first sleeve 33 to move towards the two ends of the outer casing. When the front end of the first sleeve 33 contacts the outer wall of the flange boss at the top of the outer casing, the fourth electric telescopic rod 32 is immediately commanded to stop extending. When the protrusion 36 contacts the edge of the port of the outer casing, the protrusion 36 is compressed into the first sleeve 33 by the reaction force of the outer casing, causing the elastic component 35 to contract. When the elastic component 35 contracts to the preset stroke, the touch sensor 34 is triggered, and the sensor sends a signal to the control system that the positioning is not in place.

[0036] It should be noted that this invention is a laser engraving machine for the inner wall of a new energy water-cooled motor housing. The user places the new energy water-cooled motor housing onto the outside of the positioning post 27, ensuring the bottom end of the housing is flush with the bottom surface of the inner wall of the mounting box 21. After initial alignment, the user activates the control button of the fixing mechanism 2, activating multiple third electric telescopic rods 28 on the positioning post 27. The third electric telescopic rods 28 extend uniformly, pushing the positioning plate 29 against the inner wall of the new energy water-cooled motor housing. The arc-shaped contact surface of the positioning plate 29 completely conforms to the inner wall of the housing, forming inner support. The user then activates the positioning mechanism 3, and the two fixing frames 31... Simultaneously, the fourth electric telescopic rod 32 is activated and extends, pushing the first sleeve 33 towards both ends of the outer casing. When the front end of the first sleeve 33 contacts the outer wall of the flange boss at the top of the outer casing, the fourth electric telescopic rod 32 is immediately commanded to stop extending. When the protrusion 36 contacts the edge of the outer casing, the protrusion 36 is compressed into the first sleeve 33 by the reaction force of the outer casing, causing the elastic component 35 to contract. When the elastic component 35 contracts to the preset stroke, the touch sensor 34 is triggered. The sensor sends a signal that the positioning is not in place to the control system. After receiving the signal, the control system activates the second... Motor 213, the output shaft of the second motor 213 drives a first gear 212 fixedly connected to it to rotate. Through the meshing transmission chain 211, it drives another first gear 212 to rotate synchronously, thereby driving the positioning post 27 and the new energy water-cooled motor housing sleeved on it to rotate slowly. When the protrusion 36 contacts the hole opened in the side wall of the flange boss at the top of the new energy water-cooled motor housing, the protrusion 36 inserts into the flange boss at the top of the new energy water-cooled motor housing. At this time, the elastic component 35 is released, the touch sensor 34 is no longer triggered, and the sensor sends a positioning signal to the control system. After the first electric telescopic rod 23 receives a signal and begins to extend, it drives the moving block 24 to slide vertically along the guide rail on the inner side wall of the lifting frame 22 until the moving block 24 reaches a preset position that matches the middle height of the new energy water-cooled motor housing. After the moving block 24 is in place, the second electric telescopic rod 25 starts and extends, pushing the clamping plate 26 to move towards the outer side wall of the new energy water-cooled motor housing. The two clamping plates 26 move synchronously, gradually clamping from both sides of the housing until the anti-slip texture on the clamping plate 26 is tightly attached to the outer wall of the housing, achieving lateral fixation.

[0037] After positioning is completed, the third electric telescopic rod 28 drives the positioning plate 29 to reset. Then, the first electric telescopic rod 23 drives the moving block 24 to slide the new energy water-cooled motor housing vertically upward along the guide rail on the inner side wall of the lifting frame 22 until the moving block 24 and the new energy water-cooled motor housing reach the preset position. Then, the fifth electric telescopic rod 42 starts and extends, driving the directional plate 43 to move downward in the vertical direction, so that the second sleeve 48 below the directional plate 43 is located below the port of the new energy water-cooled motor housing. Then, the third motor 41 is started, and the output shaft of the third motor 41 drives the fifth electric telescopic rod 42 to rotate, adjusting the horizontal angle of the directional plate 43. Then, the driving device of one set of electric slide grooves 44 is started, and the electric slider 45 slides horizontally along the inner side wall of the electric slide groove 44, driving the guide plate 46 to move synchronously, so that the top of the second sleeve 48 is aligned with the port directly below the new energy water-cooled motor housing, ensuring that it can be smoothly inserted into the housing later.

[0038] One set of sixth electric telescopic rods 47 is activated. The sixth electric telescopic rod 47 slowly extends, pushing the second sleeve 48 to move vertically upward, causing the sweeping rod 414 and sweeping strip 415 to gradually extend deep into the interior of the new energy water-cooled motor housing until the first cover plate 416 reaches the housing port. The sweeping rod 414 is completely within the preset cleaning area. Subsequently, the fourth motor 49 is activated. The output shaft of the fourth motor 49 drives the rotating column 412 to rotate at high speed. The rotating column 412 is slidably connected to the guide column 413, causing the guide column 413 to rotate synchronously. At the same time, the first slider 411 on the outer side of the guide column 413 slides along the inner wall of the annular track 410, thereby causing the guide column 413 to move up and down and rotate along the annular track 410. The rotation of the guide column 413 drives the sweeping rod 414 and sweeping strip 415 to rotate synchronously, cleaning... The sweeping bar 415 makes close contact with the inner wall of the new energy water-cooled motor housing, and performs high-speed sweeping of oil stains, rust, dust and other impurities on the inner wall, peeling the impurities off the inner wall. Simultaneously, the air pump 420 is started, and the air pump 420 generates negative pressure, which is transmitted to the first cover plate 416 through the first telescopic tube 419 and the fixed box 418. Multiple first leakage holes 417 at the bottom of the inner side wall of the first cover plate 416 form a negative pressure suction port, sucking in the waste residue, dust and other impurities generated during sweeping. They are then transported to the slag collection box 422 for collection through the first telescopic tube 419, the air pump 420 and the second telescopic tube 421. After cleaning is completed, the fourth motor 49 is turned off first. After the sweeping bar 414 stops rotating, the air pump 420 is turned off. Then, the sixth electric telescopic bar 47 is controlled to retract, driving the second sleeve 48 to slowly exit the new energy water-cooled motor housing and return to the initial position.

[0039] The third motor 41 is restarted, and its output shaft drives the fifth electric telescopic rod 42 to rotate, adjusting the orientation plate 43 to rotate 180 degrees. Then, the drive device of another set of electric slide rails 44 is activated, and the electric slider 45 slides horizontally along the inner wall of the electric slide rails 44, driving another guide plate 46 to move synchronously, aligning the top of the third sleeve 423 directly below the port of the new energy water-cooled motor housing. The sixth electric telescopic rod 47 is then activated, slowly extending and pushing the third sleeve 423 vertically upward, causing the rotating rod 426 to extend deep into the new energy water-cooled motor housing until the second cover plate 424 is in contact with the housing port. The omnidirectional laser 430 reaches the engraving starting position. In the control system's operating interface, the pre-designed engraving pattern is imported, and the relevant parameters of the omnidirectional laser 430 are set according to the material of the new energy water-cooled motor housing and the engraving depth requirements. The laser beam is aligned with the starting point of the preset engraving path, and the omnidirectional laser 430 emits the laser beam. At the same time, the fifth motor 425 starts, driving the rotating rod 426, the fixed block 427, and the omnidirectional laser 430 to rotate at a constant speed, achieving circumferential engraving coverage of the inner wall of the new energy water-cooled motor shell. The sixth motor 428 is started, and the output shaft of the sixth motor 428 drives the rotating block 429 to swing, thereby adjusting the emission angle of the omnidirectional laser 430 to ensure that the laser beam can cover the entire engraving area. Simultaneously, the air pump 420 is started, generating negative pressure through the third telescopic tube 432, the third sleeve 423, and the second leakage hole 431 on the second cover plate 424, which promptly sucks in the smoke and slag generated during the engraving process. The smoke and slag are then transported to the slag collection box 422 through the third telescopic tube 432, the air pump 420, and the second telescopic tube 421, preventing the smoke and slag from blocking the light path and affecting the engraving accuracy, while also preventing the slag from accumulating in the engraving area and causing secondary damage.

[0040] Once the control system detects that the entire engraving path is complete, it immediately instructs the omnidirectional laser 430 to stop emitting laser light. Simultaneously, the fifth motor 425 and the sixth motor 428 stop operating, while the air pump 420 continues to operate for three to five seconds to ensure that any remaining smoke and waste are thoroughly sucked into the slag collection box 422. After the air pump 420 stops operating, it controls the sixth electric telescopic rod 47 connected to the third sleeve 423 to retract, driving the third sleeve 423 back to its initial position. The third motor 41 is then activated, driving the fifth electric telescopic rod 42 to rotate and reset, causing the directional plate 43 to return to its initial angle. Subsequently, the fifth electric telescopic rod 42 retracts, driving the directional plate 43 to rise to a safe height. The first electric telescopic rod 23 is then activated, causing the moving block 24 and the outer casing of the new energy water-cooled motor to slide downwards along the inner wall of the lifting frame 22, returning to the initial position. The drawer of the slag collection box 422 is opened, and the collected waste, smoke, and other impurities are poured into the designated waste recycling container. The inner wall of the drawer and the interior of the slag collection box 422 are cleaned with a brush to ensure that no impurities accumulate.
