Description

Technical Field

[0001] The present invention relates to the field of processing of new energy electric vehicle battery converters, and specifically relates to a production and processing device and a processing method for a power converter of a new energy electric vehicle. Background Art

[0002] During the production process of a power converter, multiple processing devices are required for processing. After a set of processing devices complete their work, the converter is transferred to the next set of processing devices for secondary processing, which is troublesome to operate.

[0003] Chinese Patent Publication No. CN219767356U discloses a processing device for a DCDC power converter, including a base. A plurality of vertically arranged support columns are provided on the side wall of the base. The ends of the plurality of support columns away from the base are commonly connected to a horizontally arranged first support plate. A power mechanism is provided on the first support plate. A plurality of support bodies are provided on the side wall of the base, and the ends of the plurality of support bodies away from the base are commonly connected to a first processing mechanism. A second processing mechanism is provided on the side wall of the base, and the second processing mechanism is located directly below the first processing mechanism. The power mechanism includes a driver, and the output end of the driver is connected to a driving rod. Two symmetrically arranged limiting members are provided on the first processing mechanism, and the two limiting members are respectively located on both sides of the driving rod.

[0004] The above solution realizes multi-process processing at the same station by arranging multiple processing mechanisms at the same station. However, the above solution does not clearly define the structure and corresponding functions of the specific processing mechanisms. In the production and processing of the entire converter, from the initial stamping, punching, and grinding of the converter housing to the subsequent assembly, multiple processes are required. Most converter housings are provided with lids on the upper part, and the lids are installed on the converter by screws. In order to ensure that the subsequent screws can be normally screwed into the converter housing, usually only threads are opened on the converter housing, and no threads are opened on the lid. According to the process requirements, if threads are also opened on the lid, after the screws are screwed in, the connection between the lid and the converter housing can be improved. In this case, the lid needs to be covered on the converter housing, and then tapping is performed by a tapping machine. However, the lid and the converter need to be respectively positioned before tapping, which results in low processing efficiency. At the same time, the loading and unloading positions in the existing tapping process are the same, which easily causes the phenomenon of production chaos. Summary of the Invention

[0005] In view of the above problems, a production and processing device and method for a power converter of a new energy electric vehicle are provided. By arranging a receiving seat on the guide rail to receive the converter housing, and at the same time arranging a processing housing above the guide rail, and opening a sliding groove and a processing cavity on the processing housing, the receiving seat moves from the loading position of the guide rail to the unloading position of the guide rail. During the movement, the receiving seat first rises from the lowest position to the highest position. During the process of the processing unit processing the converter housing, the receiving seat is always in the highest position. After the processing is completed, the receiving seat starts to descend. When the receiving seat reaches the unloading position of the guide rail, the receiving seat is in the lowest position. Subsequently, the converter housing and the lid are removed, and the receiving seat is reset. This ensures that the threads on the processed converter housing and the lid can coincide, facilitating the subsequent screwing in of the screws, and at the same time shortening the positioning time of the converter housing and the lid.

[0006] To solve the problems of the prior art, the present invention provides a production and processing device for a power converter of a new energy electric vehicle, including a guide rail and a receiving seat arranged on the guide rail to receive the converter housing, and the receiving seat moves along the extension direction of the guide rail; a processing unit is arranged above the guide rail, and the processing unit includes a horizontally arranged processing housing.

A first spring is arranged in the first gap along the extension direction of the extension rod. The two ends of the first spring are respectively fixed to the end of the extension rod and the side wall of the lifting housing.

[0009] Preferably, a first threaded rod is vertically arranged above the pressing plate. The first threaded rod vertically penetrates through the upper part of the processing shell. The first threaded rod can only move in the vertical direction. A toothed ring is rotatably arranged on the upper part of the processing shell. The toothed ring is sleeved around the first threaded rod and is in threaded cooperation with the first threaded rod. A gear is meshed on one side of the toothed ring. A first rotary driver for driving the gear to rotate is arranged at the end of the gear.

[0010] Preferably, a fixing plate is arranged at the lower end of the first threaded rod. The fixing plate is in rotational cooperation with the first threaded rod, and the fixing plate moves synchronously along the vertical direction with the first threaded rod. A second gap is provided between the fixing plate and the pressing plate. A second spring is vertically and fixedly arranged in the second gap. A roller is rotatably arranged at the lower part of the pressing plate along the width direction of the guide rail.

[0011] Preferably, a sliding frame is arranged in parallel on one side of the guide rail. The processing shell is slidably arranged on the sliding frame along the length direction of the guide rail.

[0012] Preferably, a corrugated pipe is sleeved around the third spring. The two ends of the corrugated pipe are respectively fixedly connected to the sliding frame and the processing shell. A transfer shell is arranged at one end of the corrugated pipe. A switching valve and an air pump are respectively arranged on the transfer shell.

[0013] Preferably, a guiding seat is arranged in parallel on one side of the guide rail. Ramps are arranged at both ends of the guiding seat. A moving seat is arranged between the receiving seat and the guide rail. The moving seat is in direct contact with the guide rail. The moving seat and the guide rail together form a sliding table. A driving rod is vertically and fixedly arranged at the bottom of the receiving seat. The driving rod vertically penetrates through the moving seat and is in sliding cooperation with the moving seat. The bottom of the driving rod is always in sliding cooperation with the upper part of the guiding seat.

[0014] Preferably, a feeding cavity is arranged on one side of the processing cavity. The feeding cavity is located in the processing shell. Lids to be processed are vertically stacked in the feeding cavity. A pushing plate is movably arranged along the length direction of the processing shell at the bottom of the feeding cavity. The pushing plate is located on the side of the feeding cavity away from the processing cavity.

[0015] The present invention also relates to a production and processing method for a power converter of a new energy electric vehicle, adopting a production and processing device for a power converter of a new energy electric vehicle. The specific steps are as follows:

[0016] S1. The receiving seat receives the converter housing at one end of the guide rail. The receiving seat drives the converter housing to move towards the processing unit along the extension direction of the guide rail. When the receiving seat moves on the guide rail, it can also move in the vertical direction. During the process of the receiving seat moving towards the processing unit, it gradually rises. The receiving seat has a highest position and a lowest position in the vertical direction. The receiving seat rises to the highest position before receiving the converter housing and sliding it into the sliding groove.

[0017] S2. When the receiving seat receives the converter housing and moves to one end of the sliding groove, it continues to move along the extension direction of the guide rail. The lid is placed in the processing cavity in advance and received by the receiving block. At the same time, the pressing plate presses the upper part of the lid. When the converter housing enters the sliding groove, it pushes the receiving block away, so that the receiving block withdraws from the bottom of the lid along the width direction of the guide rail. When the converter housing completely enters the sliding groove, the converter housing is located directly below the processing cavity, and the lid in the processing cavity covers the converter housing. The receiving seat drives the processing housing to move synchronously through the converter housing.

[0018] S3. The pressing plate presses the lid on the converter housing. The tapping machine descends to tap the lid and the converter housing in sequence. After the tapping is completed, the tapping machine rises. The receiving seat drives the converter housing and the lid that have been tapped to descend together. When the receiving seat reaches the other end of the guide rail, the converter housing and the lid that have been tapped are removed together.

[0019] The beneficial effects of the present invention compared with the prior art are as follows:

[0020] 1. In the present invention, a receiving seat for receiving the converter housing is provided on the guide rail. At the same time, a processing housing is provided above the guide rail, and a sliding groove and a processing cavity are opened on the processing housing. The receiving seat moves from the loading position of the guide rail to the unloading position of the guide rail. During the moving process, the receiving seat first rises from the lowest position to the highest position. During the process of the processing unit processing the converter housing, the receiving seat is always at the highest position. After the processing is completed, the receiving seat starts to descend. When the receiving seat reaches the unloading position of the guide rail, the receiving seat is at the lowest position. Then, the converter housing and the lid are removed, and the receiving seat is reset. This ensures that the threads on the processed converter housing and the lid can coincide, facilitating the subsequent screwing of screws. It also separates the loading and unloading positions, avoiding the situation of mixed placement during loading and unloading. At the same time, the receiving seat moving along the extension direction of the guide rail can achieve automatic positioning of the lid and the converter housing without stopping when passing through the processing unit, reducing the start-stop times, reducing energy consumption, and improving processing efficiency.

[0021] 2. By sleeving a corrugated pipe around the third spring and arranging an air pump and a switching valve at the end of the corrugated pipe, when the processing shell is pushed to move, the switching valve is in the open state and the air pump is in the stopped operating state. The third spring is gradually compressed, and the air in the corrugated pipe is discharged through the open switching valve. When the tapping machine finishes the operation, the switching valve closes and the air pump starts. The air pump extracts the air in the corrugated pipe, causing the processing shell to actively move along the extension direction of the guide rail, and the moving speed of the processing shell is faster than that of the receiving seat, avoiding wear on the side wall of the processing cavity and ensuring that the lid can smoothly descend synchronously with the converter housing without slipping due to the action of a horizontal thrust force.

Detailed implementation manners

[0036] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0037] Refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 10: A production and processing device for a power converter of a new energy electric vehicle, including a guide rail 1 and a receiving seat 2 arranged on the guide rail 1 to receive the converter housing 5, and the receiving seat 2 moves along the extension direction of the guide rail 1; a processing unit 3 is arranged above the guide rail 1, and the processing unit 3 includes a processing housing 33 arranged horizontally. A processing cavity 331 is arranged vertically in the processing housing 33, and the processing cavity 331 is used to store the lid 4. A sliding groove 332 is horizontally opened at the end of the processing housing 33. The sliding groove 332 is located below the processing cavity 331 and communicates with the processing cavity 331. A receiving unit 31 is arranged in the processing housing 33. The receiving unit 31 includes a receiving block 311 movably arranged along the width direction of the guide rail 1 on the side of the sliding groove 332. The upper part of the receiving block 311 is used to receive the lid 4. A pressing plate 32 is movably arranged vertically in the processing cavity 331. The pressing plate 32 is used to press the upper part of the lid 4 received by the receiving block 311. A plurality of tapping machines 321 are arranged vertically on the pressing plate 32. The tapping ends of the tapping machines 321 face vertically downward, and the tapping machines 321 vertically penetrate through the pressing plate 32 and are slidably matched with the pressing plate 32 in the vertical direction. A chamfer is opened at the end of the receiving block 311, and the chamfer faces the end of the processing housing 33 where the sliding groove 332 is opened.

[0038] According to the requirements of the processing technology, when the traditional lid 4 is covered on the converter housing 5, the two are connected by screws. However, due to the limitations of the processing technology, usually only threads are opened on the converter housing 5, and no threads are opened on the lid 4. In this way, after using for a period of time, the lid 4 is prone to shaking. If threads are also opened on the lid 4 so that the screws are threadedly engaged with both the lid 4 and the converter housing 5 at the same time, the shaking phenomenon of the lid 4 can be avoided. However, in this case, the threads on the lid 4 and the threads on the converter housing 5 need to be completely coincident, otherwise the screws cannot be screwed in smoothly. During processing, the lid 4 needs to be covered on the converter housing 5 in advance, so the lid 4 and the converter housing 5 need to be positioned simultaneously, resulting in low efficiency. At the same time, the loading and unloading positions of the existing processing machine are the same, resulting in easy mixing during loading and unloading. Each processed lid 4 and converter housing 5 correspond to each other. If there is confusion, the screws still cannot be threadedly engaged with both the lid 4 and the converter housing 5 at the same time.

[0039] In order to avoid the above situation, a processing unit 3 is arranged on the upper part of the guide rail 1. The loading and unloading are respectively located at both ends of the guide rail 1, avoiding the mixing phenomenon during the production process. And the processing unit 3 can automatically position the converter housing 5 respectively, reducing the positioning time and improving the processing efficiency. The specific structure and working steps of the processing unit 3 are as follows:

[0040] A linear driver 3211 for driving the tapping machine 321 to lift in the vertical direction is provided at the upper part of the tapping machine 321. The two ends of the guide rail 1 are respectively the loading position and the unloading position. During processing, the converter housing 5 is first placed on the receiving seat 2. At this time, the receiving seat 2 is located at one end of the guide rail 1. At the same time, the cover 4 is also placed in the processing cavity 331 of the processing housing 33. The cover 4 is received by the receiving block 311, and the upper part of the cover 4 is pressed by the pressing plate 32. The receiving seat 2 carrying the converter housing 5 moves along the extension direction of the guide rail 1 towards the processing unit 3. During the movement of the receiving seat 2 driving the converter housing 5, the receiving seat 2 gradually rises. And when the converter housing 5 moves to one side of the sliding groove 332, the receiving seat 2 rises to the highest position. At this time, the upper end face of the converter housing 5 is coplanar with the upper end face of the receiving block 311, that is, the upper end face of the converter housing 5 is coplanar with the lower end face of the cover 4. In this way, when the receiving seat 2 drives the converter housing 5 into the sliding groove 332, after the receiving block 311 is successively squeezed out, the cover 4 can be closed on the converter housing 5. When the converter housing 5 contacts the end of the sliding groove 332, the receiving seat 2 pushes the processing housing 33 to move along the extension direction of the guide rail 1 through the converter housing 5. At this time, the processing housing 33 moves synchronously with the converter housing 5. Subsequently, the tapping machine 321 on the pressing plate 32 descends in the vertical direction and successively taps the cover 4 and the converter housing 5, so that the threads on the cover 4 and the converter housing 5 can completely coincide, ensuring that the subsequent screws can be smoothly thread-fitted with the cover 4 and the converter housing 5. After tapping, the tapping machine 321 rises, and the pressing plate 32 continues to press the cover 4. When the receiving seat 2 gradually descends while moving along the extension direction of the guide rail 1, the pressing plate 32 presses the cover 4 on the converter housing 5, so that the cover 4 descends synchronously with the converter housing 5. When the cover 4 descends below the processing housing 33, the processing housing 33 moves in the reverse direction to reset, while the receiving seat 2 continues to drive the converter housing 5 and the cover 4 to move. When the receiving seat 2 moves to the other end of the guide rail 1, the receiving seat 2 stops moving. The other end of the guide rail 1 refers to the unloading position of the guide rail 1. Subsequently, the converter housing 5 and the cover 4 on the receiving seat 2 at the unloading position of the guide rail 1 are removed, and the receiving seat 2 is reset to the loading position of the guide rail 1. In this way, the loading and unloading positions are separated, avoiding the situation of mixed placement during loading and unloading. At the same time, the receiving seat 2 moving along the extension direction of the guide rail 1 can automatically position the cover 4 and the converter housing 5 without stopping when passing through the processing unit 3, reducing the start-stop times, reducing the energy consumption, and improving the processing efficiency.

[0041] Refer to Figure 7: A lifting groove is vertically opened in the processing shell 33, and the lifting groove passes through the side of the sliding groove 332 and the side of the processing cavity 331 in the vertical direction respectively. A lifting shell 312 is arranged to move in the vertical direction in the lifting groove, and a receiving block 311 is arranged on the lifting shell 312 to move along the width direction of the guide rail 1. A winding wheel 313 is rotatably arranged on the upper part of the processing shell 33, and a weight 315 is arranged on one side of the processing shell 33 to move in the vertical direction. A rope 314 is arranged between the weight 315 and the lifting shell 312, and both ends of the rope 314 are fixedly connected to the weight 315 and the lifting shell 312 respectively, and the rope 314 is wound from the upper part of the winding wheel 313.

[0042] The lifting shell 312 has a highest position and a lowest position in the process of lifting along the lifting groove. When the lifting shell 312 is in the highest position, it is in the loading position, that is, a loading chamber 333 is provided on one side of the processing chamber 331, and the lid 4 is stacked in the loading chamber 333 along the vertical direction. The loading chamber 333 and the processing chamber 331 are connected to each other. When loading is required, the lid 4 in the loading chamber 333 is pushed into the processing chamber 331, and the lid 4 entering the processing chamber 331 is received by the receiving block 311 provided on the lifting shell 312, and the receiving block 311 is on the horizontal side of the processing chamber 331. When the lifting shell 312 is in the lowest position, it is in the processing position, and the receiving block 311 on the lifting shell 312 is on the horizontal side of the sliding groove 332, so that the receiving seat 2 receives the lid 4. After the converter housing 5 enters the sliding groove 332, the converter housing 5 can push the receiving block 311 into the lifting shell 312 in sequence. Since the weight of the cover 4 is relatively light, after the cover 4 slides into the processing chamber 331, although the lifting shell 312 drops, it cannot reach the specified processing position, and the pressing plate 32 is required to press the cover 4, so that the lifting shell 312 drops together with the cover 4. In this way, the weight of the heavy object 315 can act on the lifting shell 312, ensuring that the cover 4 can be stably clamped before reaching the processing position, avoiding the cover 4 from deflecting during the descending process of the processing chamber 331. At the same time, since the weight of the heavy object 315 is always constant, it is ensured that the clamping force of the receiving block 311 and the pressing plate 32 on the cover 4 is always constant.

[0043] Reference Figure 7 : An extension rod 316 is fixedly arranged at the end of the supporting block 311 along the width direction of the guide rail 1, and the extension rod 316 penetrates the side wall of the lifting shell 312 along the width direction of the guide rail 1. There is a first gap between one end of the extension rod 316 located on the outside of the lifting shell 312 and the side wall of the lifting shell 312, and a first spring 317 is arranged in the first gap along the extension direction of the extension rod 316, and the two ends of the first spring 317 are respectively fixedly connected to the end of the extension rod 316 and the side wall of the lifting shell 312.

[0044] After the receiving block 311 is pushed into the lifting housing 312 by the converter housing 5 and slides in, the first spring 317 is in a stretched state. After the tapping machine 321 finishes tapping, the pressing plate 32 continues to press the lid 4. When the receiving seat 2 starts to descend during the process of moving along the guide rail 1, the pressing plate 32 causes the lid 4 to descend synchronously with the receiving seat 2, ensuring that the lid 4 can be stably placed on the converter housing 5. After the receiving seat 2 completely descends, the lid 4 descends with the converter housing 5 to the lower part of the processing housing 33. At this time, the processing housing 33 no longer obstructs the converter housing 5 and the processing housing 33. Subsequently, the pressing plate 32 rises, and the receiving block 311 pressed into the lifting housing 312 pops out under the action of the first spring 317. It should be noted that when the pressing plate 32 presses the lid 4 to the lower part of the processing housing 33, the receiving block 311 on the lifting housing 312 is located above the pressing plate 32. Under the action of the heavy object 315, the pressing plate 32 rises with the lifting housing 312, and the lifting housing 312 drives the receiving block 311 to rise to the loading position. A chamfer is also provided below the end of the receiving block 311. During the process of the pressing plate 32 rising, when the pressing plate 32 passes through the receiving block 311, it can smoothly press the receiving block 311 into the lifting housing 312. At the same time, under the action of the first spring 317, when the pressing plate 32 rises above the receiving block 311, the receiving block 311 pops out again. When the pressing plate 32 rises to the highest position, the gap formed between the pressing plate 32 and the receiving block 311 is used to store the lid 4 to be processed.

[0045] Refer to Figure 2 : A first threaded rod 322 is vertically arranged above the pressing plate 32. The first threaded rod 322 vertically penetrates through the upper part of the processing housing 33. The first threaded rod 322 can only move in the vertical direction. A toothed ring 323 is rotatably arranged on the upper part of the processing housing 33. The toothed ring 323 is sleeved on the periphery of the first threaded rod 322 and is in threaded cooperation with the first threaded rod 322. A gear 324 is meshed on one side of the toothed ring 323. A first rotary driver 325 for driving the gear 324 to rotate is arranged at the end of the gear 324.

[0046] Refer to Figure 10 and Figure 12 : A fixing plate 326 is arranged at the lower end of the first threaded rod 322. The fixing plate 326 is rotatably matched with the first threaded rod 322, and the fixing plate 326 moves synchronously with the first threaded rod 322 in the vertical direction. A second gap exists between the fixing plate 326 and the pressing plate 32. A second spring 327 is vertically and fixedly arranged in the second gap. A roller 328 is rotatably arranged at the lower part of the pressing plate 32 in the width direction of the guide rail 1.

[0047] The first rotary driver 325 is preferably a servo motor. When the pressing plate 32 needs to be lifted or lowered, the first rotary driver 325 drives the toothed ring 323 to rotate through the gear 324, so that the toothed ring 323 drives the first threaded rod 322 to descend. The first threaded rod 322 presses the pressing plate 32 through the fixing plate 326 and the second spring 327. When the processing is completed and before the receiving seat 2 starts to descend, the second spring 327 is in a compressed state. Thus, when the receiving seat 2 starts to descend, the pressing plate 32 can press the lid 4 onto the converter housing 5 under the action of the second spring 327. At the same time, rollers 328 are provided at the bottom of the pressing plate 32 to reduce the friction coefficient between the pressing plate 32 and the lid 4 in the horizontal direction, ensuring that when the processing shell 33 is reset, the pressing plate 32 will not push the lid 4 away from the converter housing 5.

[0048] Refer to Figure 5 : A sliding frame 35 is arranged in parallel on one side of the guide rail 1. The processing shell 33 is slidably arranged on the sliding frame 35 along the length direction of the guide rail 1. A third spring 34 is horizontally arranged between the sliding frame 35 and the processing shell 33. The two ends of the third spring 34 are respectively fixedly connected to the sliding frame 35 and the processing shell 33.

[0049] Refer to Figure 5 and Figure 6 : A bellows 36 is sleeved outside the third spring 34. The two ends of the bellows 36 are respectively fixedly connected to the sliding frame 35 and the processing shell 33. A transfer shell 37 is arranged at one end of the bellows 36. A switching valve 38 and an air pump 39 are respectively arranged on the transfer shell 37. The transfer shell 37 is communicated with the bellows 36.

[0050] When the converter housing 5 enters the sliding groove 332 and reaches one end of the sliding groove 332, the receiving seat 2 moves along the extending direction of the guide rail 1 towards the discharging end of the guide rail 1. The receiving seat 2 drives the processing housing 33 to move synchronously through the converter housing 5 on its upper part. At this time, the processing housing 33 moves on the sliding frame 35, the switching valve 38 is in the open state, and the air pump 39 is in the stopped running state. The moving processing housing 33 squeezes the third spring 34. After the tapping machine 321 finishes tapping, the pressing plate 32 presses the lid 4. During the movement of the receiving seat 2, it gradually descends. At this time, the lid 4 descends together with the converter housing 5. In order to avoid the reaction force of the squeezed third spring 34 on the processing housing 33, after the tapping machine 321 finishes tapping, the switching valve 38 is closed, and the air pump 39 starts and extracts the air in the bellows 36 through the intermediate housing 37, causing the bellows 36 to actively contract, and then causing the processing housing 33 to move independently on the sliding frame 35, and the moving speed of the processing housing 33 is greater than the moving speed of the receiving seat 2. In this way, during the process of the pressing plate 32 pressing the lid 4 below the processing housing 33, the end of the lid 4 will not directly contact the side wall of the processing cavity 331, and at the same time, the side wall of the converter housing 5 will not directly contact the side wall of the processing cavity 331, avoiding wear on the side wall of the processing cavity 331 and ensuring that the lid 4 can smoothly descend synchronously with the converter housing 5 without slipping due to the action of a horizontal thrust. When the receiving seat 2 descends to the lowest position, the air pump 39 stops running, the switching valve 38 is opened, and the reset elastic force generated by the third spring 34 pushes the processing housing 33, causing the processing housing 33 to reset to one end of the sliding frame 35 close to the loading position of the guide rail 1.

[0051] Refer to Figure 3 and Figure 4 : A guiding seat 11 is arranged in parallel on one side of the guide rail 1. Ramps are provided at both ends of the guiding seat 11. A moving seat 12 is arranged between the receiving seat 2 and the guide rail 1. The moving seat 12 is in direct contact with the guide rail 1. The moving seat 12 and the guide rail 1 together form a sliding table. A driving rod 13 is vertically and fixedly arranged at the bottom of the receiving seat 2. The driving rod 13 vertically penetrates the moving seat 12 and is in sliding fit with the moving seat 12. The bottom of the driving rod 13 is always in sliding fit with the upper part of the guiding seat 11.

[0052] The receiving seat 2 moves from the loading position of the guide rail 1 to the unloading position of the guide rail 1. During the movement, the receiving seat 2 first rises from the lowest position to the highest position. During the process of the processing unit 3 processing the converter housing 5, the receiving seat 2 always remains at the highest position. After the processing is completed, the receiving seat 2 starts to descend. When the receiving seat 2 reaches the unloading position of the guide rail 1, the receiving seat 2 is at the lowest position. After removing the converter housing 5 and the lid 4 on the receiving seat 2, the receiving seat 2 moves from the unloading end to the loading end. During the process of the receiving seat 2 resetting from the unloading end to the loading end, although the receiving seat 2 will rise again, since the converter housing 5 is not placed on the receiving seat 2, the receiving seat 2 rising to the highest position in this way is located below the processing housing 33.

[0053] Refer to Figure 8 and Figure 9 : A loading chamber 333 is provided on one side of the processing chamber 331. The loading chamber 333 is located in the processing housing 33. The lids 4 to be processed are vertically stacked in the loading chamber 333. A pushing plate 334 is movably arranged along the length direction of the processing housing 33 at the bottom of the loading chamber 333. The pushing plate 334 is located on the side of the loading chamber 333 away from the processing chamber 331.

[0054] A second threaded rod 335 is rotatably arranged along the length direction of the processing housing 33 in the loading chamber 333. The second threaded rod 335 is located on one side of the stacked lids 4. The second threaded rod 335 penetrates through the pushing plate 334 along the length direction of the processing housing 33 and is in threaded cooperation with the pushing plate 334. A second rotary driver 336 for driving the second threaded rod 335 to rotate is arranged at the end of the second threaded rod 335. The second rotary driver 336 is preferably a servo motor. When the second rotary driver 336 is started, the second rotary driver 336 drives the second threaded rod 335 to rotate, so that the pushing plate 334 moves along the length direction of the processing housing 33. The pushing plate 334 is used to push the stacked lids 4 in the loading chamber 333 into the processing chamber 331.

[0055] Refer to Figures 1 - 12 : The present invention also relates to a production and processing method for a power converter of a new energy electric vehicle. Using a production and processing device for a power converter of a new energy electric vehicle, the specific steps are as follows:

[0056] S1. The receiving seat 2 receives the converter housing 5 at one end of the guide rail 1. The receiving seat 2 drives the converter housing 5 along the extending direction of the guide rail 1 towards the processing unit 3. When the receiving seat 2 moves on the guide rail 1, it can also move in the vertical direction. During the process of the receiving seat 2 moving towards the processing unit 3, it gradually rises. The receiving seat 2 has a highest position and a lowest position in the vertical direction. The receiving seat 2 rises to the highest position before receiving the converter housing 5 and sliding into the sliding groove 332.

[0057] S2. When the receiving seat 2 moves the converter housing 5 to one end of the sliding groove 332 and continues to move along the extending direction of the guide rail 1, the cover 4 is placed in the processing cavity 331 in advance and received by the receiving block 311. At the same time, the pressing plate 32 presses the upper part of the cover 4. When the converter housing 5 enters the sliding groove 332, it pushes the receiving block 311 away, so that the receiving block 311 withdraws from the bottom of the cover 4 along the width direction of the guide rail 1. When the converter housing 5 completely enters the sliding groove 332, the converter housing 5 is located directly below the processing cavity 331, and the cover 4 in the processing cavity 331 covers the converter housing 5. The receiving seat 2 drives the processing shell 33 to move synchronously through the converter housing 5;

[0058] S3. The pressing plate 32 presses the cover 4 on the converter housing 5, and the tapping machine 321 descends to tap the cover 4 and the converter housing 5 in sequence. After tapping is completed, the tapping machine 321 rises, and the receiving seat 2 drives the tapped converter housing 5 and the cover 4 to descend together. When the receiving seat 2 reaches the other end of the guide rail 1, the tapped converter housing 5 and the cover 4 are removed together.

[0059] Working principle: During processing, the converter housing 5 is first placed on the receiving seat 2. At this time, the receiving seat 2 is located at one end of the guide rail 1. At the same time, the cover 4 is also placed in the processing cavity 331 of the processing shell 33. The cover 4 is received by the receiving block 311, and the upper part of the cover 4 is pressed by the pressing plate 32. The receiving seat 2 carrying the converter housing 5 moves along the extending direction of the guide rail 1 towards the processing unit 3. During the process of the receiving seat 2 driving the converter housing 5 to move, the receiving seat 2 gradually rises. And when the converter housing 5 moves to one side of the sliding groove 332, the receiving seat 2 rises to the highest position. At this time, the upper end face of the converter housing 5 is coplanar with the upper end face of the receiving block 311, that is, the upper end face of the converter housing 5 is coplanar with the lower end face of the cover 4. In this way, when the receiving seat 2 drives the converter housing 5 into the sliding groove 332, after the receiving block 311 is successively squeezed out, the cover 4 can be closed on the converter housing 5. When the converter housing 5 contacts the end of the sliding groove 332, the receiving seat 2 drives the processing shell 33 to move along the extending direction of the guide rail 1 through the converter housing 5. At this time, the processing shell 33 moves synchronously with the converter housing 5. Subsequently, the tapping machine 321 on the pressing plate 32 descends vertically and taps the cover 4 and the converter housing 5 in sequence, so that the threads on the cover 4 and the converter housing 5 can completely coincide, ensuring that the subsequent screws can be smoothly thread-fitted with the two.

[0060] After tapping is completed, the tapping machine 321 rises, and the pressing plate 32 continues to press the lid 4. While the receiving seat 2 moves along the extension direction of the guide rail 1 and gradually descends, the pressing plate 32 presses the lid 4 onto the converter housing 5, causing the lid 4 to descend synchronously with the converter housing 5. When the lid 4 descends below the processing shell 33, the processing shell 33 moves in the reverse direction to reset, while the receiving seat 2 continues to drive the converter housing 5 and the lid 4 to move. When the receiving seat 2 moves to the other end of the guide rail 1, which refers to the discharging position of the guide rail 1, the receiving seat 2 stops moving. Then, the converter housing 5 and the lid 4 on the receiving seat 2 at the discharging position of the guide rail 1 are removed, and the receiving seat 2 resets to the loading position of the guide rail 1. In this way, the loading and discharging positions are separated, avoiding the situation of mixed placement during loading and discharging. At the same time, the receiving seat 2 moving along the extension direction of the guide rail 1 can achieve automatic positioning of the lid 4 and the converter housing 5 without stopping when passing through the processing unit 3, reducing the number of starts and stops, reducing energy consumption, and improving processing efficiency.

[0061] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
