Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts processing technology, specifically a shell edge cutting device. Background Technology

[0002] With the continuous development of the electric vehicle industry, converters play an irreplaceable role as energy transfer components in electric vehicles. Existing low-speed electric vehicles mostly use DC-DC converters to convert the voltage output from the battery before supplying it to the motor driver, which in turn powers the vehicle's electrical systems, such as lights, wipers, and displays, to improve energy efficiency. Since electric vehicles mostly operate outdoors, converters must be waterproof to meet the environmental requirements and prevent circuit board damage from moisture.

[0003] After the converter housing is die-cast, the opening of the housing usually needs to be trimmed. In the prior art, after trimming the housing, it is not convenient to quickly remove the housing and the trimmed edges. Therefore, we have introduced a housing trimming device. Utility Model Content

[0004] The purpose of this utility model is to provide a shell trimming device, which not only facilitates trimming of the converter shell with high trimming efficiency and good trimming accuracy, but also facilitates material handling by workers, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shell trimming device includes a base and a top seat. The base and the top seat are fixedly connected by four sliding rods. A movable plate is slidably arranged between the four sliding rods. A hydraulic cylinder is fixed between the top seat and the movable plate. A movable seat is provided on the upper end of the base through a linkage mechanism. A placement groove is provided in the middle of the top of the movable seat. A trimming ring is fixedly arranged along the inner edge of the opening of the placement groove. A positioning block is provided in the placement groove below the trimming ring. A connecting block is fixedly arranged in the middle of the upper end of the positioning block. A displacement mechanism is provided between the connecting block and the movable plate.

[0007] Furthermore, the linkage mechanism includes a motor, a turntable is fixedly provided at the output end of the motor, and a rotating shaft is rotatably provided at the upper edge of the turntable via a rolling bearing. The upper end of the rotating shaft is rotatably connected to the center of the bottom of the movable seat.

[0008] Furthermore, multiple support legs are evenly fixed at the bottom of the movable seat.

[0009] Furthermore, the lower end of the support leg is configured with a rounded head.

[0010] Furthermore, the displacement mechanism includes an electric push rod, which is fixedly mounted on the bottom of the movable plate, and the output end of the electric push rod is fixedly connected to the side wall of the connecting block.

[0011] Furthermore, the bottom of the placement groove is provided with a rectangular hole, a rectangular rod is slidably disposed in the rectangular hole, and the upper end of the rectangular rod extends into the placement groove and is fixedly provided with a top plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This shell trimming device, comprising a top seat, slide rod, moving plate, base, motor, support legs, movable seat, hydraulic cylinder, connecting block, electric push rod, trimming ring, rotating shaft, turntable, positioning block, top plate, and rectangular rod, places the die-cast shell with its opening facing upwards into the placement slot. Activating the hydraulic cylinder moves the moving plate downwards, which in turn moves the positioning block downwards via the connecting block. The positioning block engages inside the shell, causing the lower end of the shell to press firmly against the top plate. Activating the motor rotates the turntable, which in turn rotates the movable seat via the rotating shaft. The movable seat then moves the trimming ring to perform a circumferential trimming of the shell's opening. The electric push rod pushes the positioning block to ensure a complete trimming. After trimming, activating the hydraulic cylinder moves the moving plate upwards, which in turn moves the positioning block back to its original position. At this point, the rectangular rod pushes upwards, causing the top plate to move upwards. The top plate then pushes the shell and the trimmed edge out of the placement slot, allowing for quick removal of the shell. This device not only facilitates trimming of converter shells with high efficiency and precision but also makes it easy for workers to handle the material. Attached Figure Description
