Abstract
Description
Technical Field
[0001] This utility model relates to the field of power battery technology, specifically to a positioning fixture for the end plate of a power battery module. Background Technology
[0002] The module end plate is a crucial component in power batteries, primarily used for fixing and supporting the battery module. It constantly protects the structural stability and safety of the battery module. End plates are typically made of high-strength aluminum alloy through extrusion molding, enabling them to withstand significant mechanical stress, providing good corrosion resistance, and aiding in heat dissipation. After extrusion molding, the end plates need to be CNC machined to meet the customer's final requirements. However, improper positioning during machining can easily lead to dimensional errors, resulting in large batch defects and significant losses for the company. To address this issue, an end plate positioning fixture was designed, which not only solves the aforementioned problems but also significantly improves machining efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a power battery module end plate positioning fixture with a reasonable structural design, adopting a one-out-four design, high processing efficiency, automatic clamping, and high safety, reliability, and precision.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a power battery module end plate positioning fixture, including a support base, a limiting block, a side cylinder, a rotary cylinder, and a pressure column. Multiple side cylinders are arranged on the side of the support base, and multiple rotary cylinders are arranged at intervals above the support base. A limiting groove for mounting aluminum end plates is provided between the rotary cylinders. A limiting block is provided on the outer side of one corner of the limiting groove. The limiting block is installed on the support base, and the pressure column is arranged on the rotating rod at the upper end of the rotary cylinder.
[0005] Preferably, the outer side of the limiting groove is provided with a mounting groove for mounting a rotary cylinder and a limiting block.
[0006] Preferably, four limiting grooves are provided.
[0007] The beneficial effects of this utility model are: the structure of this utility model is reasonable, the operation is convenient and reliable, the one-out-four design is adopted, the processing efficiency is high, the automatic clamping is safe, reliable and highly accurate. Attached Figure Description
[0008] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments;
[0009] Figure 1 This is an exploded structural diagram of the present invention;
[0010] Figure 2 This is a schematic diagram of the structure of this utility model; Detailed Implementation
[0011] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0012] Reference Figure 1-2 The specific embodiment adopts the following technical solution: a power battery module end plate positioning fixture, including a support base 1, a limiting block 2, a side cylinder 3, a rotary cylinder 4 and a pressure column 5. Multiple side cylinders 3 are arranged on the side of the support base 1, and multiple rotary cylinders 4 are arranged at intervals above the support base 1. A limiting groove 7 for mounting aluminum end plates 6 is arranged between the rotary cylinders 4. A limiting block 2 is arranged on the outer side of one corner of the limiting groove 7. The limiting block 2 is installed on the support base 1, and the pressure column 5 is arranged on the rotating rod at the upper end of the rotary cylinder 4.
[0013] It is worth noting that the outer side of the limiting groove 7 is provided with a mounting groove 8 for mounting the rotary cylinder 4 and the limiting block 2.
[0014] In addition, four limiting grooves 7 are provided.
[0015] The main operation method of this specific embodiment is as follows: After fixing the limiting block on the support base, place the module end plate to be processed into the limiting groove. After turning on the power, the side cylinder will move to hold the end plate in place. Finally, the rotary cylinder will drive the pressure column to rotate 90 degrees and press the end plate in the forward direction (the non-working position of the rotary cylinder is parallel to the end plate) to prevent processing shaking and causing processing errors.
[0016] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
