Description

TECHNICAL FIELD

[0001] The application relates to the technical field of battery shell manufacturing, in particular to a new energy automobile battery shell mounting hole position degree gauge. BACKGROUND

[0002] The new energy automobile battery shell is a peripheral safety barrier for protecting the battery module, and comprises an upper shell and a lower shell. The battery pack used by the new energy automobile is installed in an inner cavity enclosed by the upper shell and the lower shell, and the upper shell and the lower shell are fastened by fasteners. When the lower shell is manufactured, mounting holes are pre-set on the lower shell for fastening the upper shell and the lower shell in the next process.

[0003] The pre-set mounting holes on the lower shell cannot have position degree out-of-tolerance phenomenon. In the actual production process, after the lower shell parts are welded into a lower shell assembly through welding, stirring welding and other processes, the assembly gauge is used at the assembly detection station to detect whether the position degree and the profile degree meet the requirements of the drawings. The assembly gauge is large in size and fixedly arranged, and is inconvenient to use. It can only be used in a specified area. When a single product after welding needs to be inspected and confirmed, it cannot be flexibly and portably checked, and therefore the industry needs a lightweight and portable inspection gauge for the mounting hole position degree of the new energy automobile battery shell.

[0004] To solve the above problems, the application provides a new energy automobile battery shell mounting hole position degree gauge. Content of the utility model

[0005] The new energy automobile battery shell mounting hole position degree gauge provided by the application adopts the following technical scheme:

[0006] The new energy automobile battery shell mounting hole position degree gauge comprises a portable ruler mechanism, uniform distribution positioning mechanisms are arranged opposite to each other in the portable ruler mechanism, limiting mechanisms are arranged on the outer walls of the positioning mechanisms, the limiting mechanisms and the portable ruler mechanism are mutually clamped, and portable handles that are mutually symmetrical are arranged at the middle positions of the top of the portable ruler mechanism.

[0007] Further, the portable ruler mechanism comprises a portable ruler main body, a sliding groove is arranged through the top of the portable ruler main body, and a gap groove is arranged through one side of the long edge of the portable ruler main body, and the sliding groove and the gap groove are mutually communicated.

[0008] Further, the portable handles are arranged on both sides of the sliding groove at the top of the portable ruler main body, and the sliding groove and the gap groove mutually form a cross shape.

[0009] Further, the positioning mechanisms comprise rotating nuts, positioning pins are arranged through the rotating nuts, limiting blocks are arranged at the top of the positioning pins, the limiting blocks are arranged in the gap grooves, and the positioning pins are arranged in the sliding grooves.

[0010] Furthermore, the diameter of each limiting block is larger than the diameter of the positioning pin, the limiting block and the rotating nut are screwed together, and the end of the positioning pin away from the limiting block is treated with an acute angle.

[0011] Furthermore, the limiting mechanism includes a limiting card, and each limiting card has a symmetrical card slot at its bottom. Each of the symmetrical card slots has a uniformly distributed abutting protrusion on one side opposite to the other. The limiting card is clamped to the portable ruler body by the abutting protrusion.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The precision-designed positioning and limiting mechanisms ensure accurate measurement of the battery casing mounting hole position. The sharp-angle treatment of the positioning pin and the tight clamping of the abutment protrusion further improve the accuracy and stability of the measurement. The portable ruler mechanism makes the entire fixture easy to carry and operate, suitable for use in various environments. The addition of a portable handle allows operators to easily grip and move the fixture, improving work efficiency. The positioning and limiting mechanisms allow the fixture to adapt to battery casing mounting holes of different sizes and shapes, improving its versatility and practicality. By adjusting the rotating nut, the height and position of the positioning mechanism can be flexibly adjusted to meet different measurement needs. Attached Figure Description

[0022] Example:

[0023] This application discloses a tool for measuring the position of mounting holes in new energy vehicle battery cases. Please refer to [link / reference]. Figs. 1-3 The device includes a portable ruler mechanism 1, within which are evenly distributed positioning mechanisms 3. Each positioning mechanism 3 has a limiting mechanism 4 on its outer wall, and the limiting mechanisms 4 engage with the portable ruler mechanism 1. A symmetrical portable handle 2 is located at the top center of the portable ruler mechanism 1. This new energy vehicle battery casing mounting hole position gauge is a high-precision measuring tool integrating a portable ruler mechanism, positioning mechanisms, limiting mechanisms, and portable handles. By precisely aligning and fixing the mounting holes on the battery casing, this gauge can accurately measure the positional accuracy of the mounting holes, ensuring the manufacturing quality and installation performance of the new energy vehicle battery casing. Its portable design allows operators to easily carry and operate it in various environments, improving work efficiency and measurement accuracy.

[0024] The portable ruler mechanism 1 includes a portable ruler body 101. A sliding groove 102 extends through the top of the portable ruler body 101, and a clearance groove 103 extends through one of the long sides of the portable ruler body 101. The sliding groove 102 and the clearance groove 103 are interconnected. A portable handle 2 is located on both sides of the sliding groove 102 at the top of the portable ruler body 101. The sliding groove 102 and the clearance groove 103 form a cross shape. A through sliding groove 102 is designed at the top of the portable ruler body 101. This sliding groove 102 not only provides a sliding track for other components but also allows the entire measuring tool to be flexibly adjusted during measurement to accommodate battery casing mounting holes of different sizes and shapes. The design of the sliding groove 102 fully considers the accuracy of measurement and the convenience of operation. A clearance groove 103 also extends through one of the long sides of the portable ruler body 101. This clearance groove 103 is interconnected with the sliding groove 102, together forming a cross-shaped structure. This design not only makes the portable ruler mechanism 1 more compact and robust in structure, but also provides more space options for the arrangement of the positioning mechanism 3 and the limiting mechanism 4. Meanwhile, the cross-shaped structure facilitates the operator's observation and alignment of the mounting holes during measurement, improving measurement accuracy and efficiency. The portable handles 2 are located on both sides of the sliding groove 102 at the top of the portable ruler body 101. The design of these two portable handles 2 conforms to ergonomic principles, allowing the operator to easily grip and move the entire measuring tool. Whether in a confined workspace or a complex operating environment, the portable handles 2 provide the operator with a stable and comfortable grip experience.

[0025] The positioning mechanism 3 includes a rotating nut 301, with a positioning pin 302 passing through each nut 301. Each positioning pin 302 has a limiting block 303 at its top, located within a clearance groove 103. The positioning pins 302 are located within a sliding groove 102. The diameter of each limiting block 303 is larger than the diameter of the positioning pin 302. The limiting blocks 303 and the rotating nut 301 are screwed together. The end of each positioning pin 302 away from the limiting block 303 is sharp-angled. The rotating nut 301 is the basic component of the positioning mechanism 3, providing a stable screwing platform for securely mounting other components. By rotating the rotating nut 301, the overall height and position of the positioning mechanism 3 can be adjusted to accommodate battery casing mounting holes of different sizes and shapes. The positioning pins 302 pass through the rotating nut 301 and extend into the sliding groove 102. The top of the positioning pin 302 is provided with a limiting block 303, which is located in the relief groove 103 and serves to limit the movement range of the positioning pin 302. At the same time, the diameter of the limiting block 303 is larger than the diameter of the positioning pin 302, so that the limiting block 303 can be screwed into the rotating nut 301, thereby further fixing the position of the positioning mechanism 3.

[0026] The limiting mechanism 4 includes a limiting card 401. Each limiting card 401 has a symmetrical slot 402 at its bottom. Each symmetrical slot 402 has evenly distributed abutment protrusions 403 on one side of each opposite side. The limiting card 401 is clamped to the portable ruler body 101 via the abutment protrusions 403. The limiting mechanism 4 is an important component of the new energy vehicle battery casing mounting hole position gauge. It is mainly responsible for fixing the position of the positioning mechanism 3 on the portable ruler body 101, preventing displacement or shaking during measurement. The limiting mechanism 4 mainly consists of three parts: the limiting card 401, the slots 402, and the abutment protrusions 403. The limiting card 401 is the main component of the limiting mechanism 4, and it is designed to be sufficiently robust to withstand various forces and pressures during the measurement process. At the bottom of the limiting card 401, symmetrical slots 402 are provided. These slots 402 provide space for the installation and fixation of the abutment protrusions 403. Evenly distributed abutment protrusions 403 are provided on opposite sides of each slot 402. These abutment protrusions 403 are designed to be small and robust, allowing them to make close contact with the surface of the portable ruler body 101 and securely clamp the limiting card 401 onto the portable ruler body 101 through friction. The even distribution of the abutment protrusions 403 ensures the stability and reliability of the limiting card 401 on the portable ruler body 101. When the limiting card 401 is clamped onto the portable ruler body 101 by the abutment protrusions 403, the limiting mechanism 4 can effectively fix the position of the positioning mechanism 3. This design not only improves the accuracy of measurement but also makes the entire fixture more compact and stable in structure.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
