Description

Technical Field

[0001] This utility model relates to the field of housing casting size measurement technology, specifically a size measurement device for high-voltage connector housing castings for electric vehicles. Background Technology

[0002] Electric vehicle high-voltage connector housing castings are manufactured through a casting process. They are an external structure used to house and protect the internal conductive components of the high-voltage connector. The dimensions of the high-voltage connector housing castings directly affect the electrical clearance, which is a key parameter to ensure electrical safety. Inaccurate dimensions may result in an insufficient electrical clearance, increasing the risk of short circuits and arcing, thereby causing safety accidents.

[0003] Currently, when measuring the high-voltage connector housing castings for electric vehicles, the housing castings are generally placed directly on a table and their height is measured using a height gauge. If the table or the housing casting is impacted during the inspection, the housing casting may separate from the height gauge, leading to test failure, or even causing the housing casting to fall off the table and deform. Summary of the Invention

[0004] This invention provides a dimensional measuring device for high-voltage connector housing castings in electric vehicles. It can use a clamping mechanism to drive multiple clamping blocks to clamp the housing casting placed at the center of the clamping mechanism, thereby reducing the problem of failure in height gauge inspection of housing castings.

[0005] To achieve the above objectives, a dimensional measuring device for a high-voltage connector housing casting in an electric vehicle is provided. The device includes a mounting base, a clamping mechanism fixedly connected to the center of the upper surface of the mounting base, and a clamping block arranged on the side of the clamping mechanism near the center of the mounting base. Several clamping blocks are evenly distributed and fixedly connected to the clamping mechanism. A rotating groove is formed on the outer side of the top surface of the mounting base, and a rotating ring is rotatably connected to the inner side of the rotating groove. A height gauge is fixedly connected to the upper end of the rotating ring, with the measuring end of the height gauge near the center of the mounting base. By configuring the clamping mechanism and the clamping blocks to cooperate, the clamping mechanism drives multiple clamping blocks to move synchronously in opposite directions, thereby clamping the housing casting placed at the center of the clamping mechanism. By configuring the rotating ring and the height gauge to cooperate, the rotating ring can adjust the measuring position of the height gauge, allowing the user to move the height gauge to a suitable position for measurement when using it to check the height of the housing casting.

[0006] According to the aforementioned dimensional measuring device for high-voltage connector housing castings in electric vehicles, the clamping mechanism includes a fixed disk, a limiting groove, a drive disk, a drive gear ring, a drive groove, a clamping plate, a drive column, a gear, a motor, and a fixed frame. The drive gear ring is rotatably connected to the upper surface of the mounting base. By setting the mutual cooperation between the drive gear ring and the mounting base, the drive gear ring is limited, making the drive gear ring more stable during rotation.

[0007] According to the aforementioned dimensional measuring device for high-voltage connector housing castings in electric vehicles, the fixed disk is disposed inside the drive gear ring, and the fixed disk is fixedly connected to the top surface of the mounting base. A plurality of limiting grooves are formed on the upper surface of the fixed disk and correspond to the clamping blocks. By positioning the fixed disk inside the drive gear ring, the drive gear ring contacts the fixed disk, further limiting the rotation of the drive gear ring and making its rotation more stable.

[0008] According to the aforementioned dimensional measuring device for high-voltage connector housing castings for electric vehicles, the clamping plate is slidably connected to the inner side of the limiting groove, and the side of the clamping plate near the center of the mounting base is fixedly connected to the side of the clamping block that is away from it. By setting the mutual cooperation between the clamping plate and the clamping block, the clamping plate moves, thereby driving the clamping block to move synchronously, allowing the clamping block to clamp.

[0009] According to the aforementioned dimensional measuring device for high-voltage connector housing castings in electric vehicles, the drive column is fixedly connected to the upper surface of the clamping plate and to the side away from the center of the mounting base. The drive disk is disposed on the upper surface of the fixed disk, and the drive slots are formed on the top surface of the drive disk. Several drive slots are provided and correspond to the clamping blocks. The drive column is slidably connected to the inner side of the drive slots. By rotating the drive disk, the drive column slides within the drive slots, causing the drive column to move the clamping plates synchronously towards or away from each other, thereby completing the clamping and releasing.

[0010] According to the dimensional measuring device for high-voltage connector housing castings in electric vehicles, the surfaces of the drive groove and the drive column are mutually fitted, and the contact surface between the drive groove and the drive column is set to a smooth state. By setting the contact surface between the drive groove and the drive column to a smooth state, the friction is reduced, making the sliding of the drive column inside the drive groove more stable.

[0011] According to the aforementioned dimensional measuring device for high-voltage connector housing castings in electric vehicles, the outer surface of the drive disk is fixedly connected to the upper inner side of the drive gear ring, the gear is meshed with the outer side of the drive gear ring, the gear is rotatably connected to the surface of the mounting base, the fixing frame is fixedly connected to the upper surface of the mounting base, the motor is fixedly mounted inside the fixing frame, and the output end of the motor is fixedly connected to the inner center of the gear. The motor drives the gear to rotate, thereby causing the drive gear to drive the drive disk to rotate synchronously, thus synchronously clamping or releasing the load.

[0012] According to the aforementioned dimensional measuring device for a high-voltage connector housing casting in an electric vehicle, the clamping block is made of rubber, and the contact surface between the rotating ring and the rotating groove is roughened. By making the clamping block of rubber, it provides cushioning when in contact with the housing casting, reducing wear on the housing casting. By making the contact surface between the rotating ring and the rotating groove rough, the friction is increased, resulting in greater stability when the rotating ring needs to stop rotating.

[0013] The beneficial effects of this utility model are as follows: By setting up the mutual cooperation between the clamping mechanism, clamping blocks and mounting base, the clamping mechanism drives multiple clamping blocks to move synchronously in opposite directions, thereby clamping the shell casting placed at the center of the clamping mechanism. This reduces the problem of the shell casting separating from the height gauge, which could lead to detection failure or even dropping and deformation. By setting up the mutual cooperation between the rotating ring and the height gauge, the rotating ring can drive the height gauge to adjust its measuring position, allowing the user to move the height gauge to the appropriate position for detection based on the area of ​​the shell casting.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] The drive column 2207 is fixedly connected to the upper surface of the clamping plate 2206 and to the side away from the center of the mounting base 1. The drive disk 2203 is set on the upper surface of the fixed disk 2201. The drive groove 2205 is opened on the top surface of the drive disk 2203.
