During the production and processing of new energy battery casings, airtightness testing is essential to ensure sealing and prevent moisture and oxygen ingress that could lead to short circuits, oxidation, or thermal runaway, thus guaranteeing safety and lifespan. Airtightness testing requires the use of an anti-deformation fixture, a device specifically designed to fix and protect the battery casing during airtightness testing. Its core function is to prevent casing deformation under pressure, which could lead to test distortion or structural damage. However, current anti-deformation fixtures for airtightness testing still have the following shortcomings:

[0003] For example, patent document CN212807476U discloses an anti-deformation tooling for airtightness testing of the casings of various new energy batteries. This anti-deformation tooling for airtightness testing of various new energy battery casings has a simple structure, low manufacturing and maintenance costs, and can effectively suppress deformation of the battery casing, effectively avoiding damage to the battery casing during airtightness testing, and improving the accuracy and consistency of airtightness testing. However, it is not convenient to flexibly adjust the fixing mechanism, which means it cannot achieve limiting of new energy battery casings of different sizes. Utility Model Content

[0004] The purpose of this utility model is to provide a deformation-resistant tooling for airtightness testing of new energy battery casings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant fixture for airtightness testing of new energy battery casings, comprising a fixture fixing base and an adjustment assembly. The fixture fixing base is an integrated structure, and a fixing base plate is installed on the lower surface of the fixture fixing base. The adjustment assembly is located on the upper side of the fixture fixing base and includes a fixed support frame, a support cross plate, a movable frame, a support connecting plate, a fixing threaded hole, a fixing bolt, a hydraulic push rod, and a limiting plate. The fixed support frame is located at the front and rear ends of the upper surface of the fixture fixing base, and a support cross plate is provided at the upper end of the inner side of the fixed support frame. Two sets of support cross plates are symmetrically arranged, and the movable frame is slidably connected to the surface of the support cross plate. A support connecting plate is installed on the inner surface of the movable frame.

[0006] Furthermore, both the supporting cross plate and the movable frame surface are provided with fixing threaded holes, and fixing bolts are threadedly connected to the inside of the fixing threaded holes.

[0009] Furthermore, the tooling fixture and the fixed base plate are an integrated structure that is tightly connected, and the surface of the fixed base plate is provided with a limiting component for limiting the position.

[0010] Furthermore, the limiting component includes a supporting plate, a supporting cylinder, a threaded supporting rod, a limiting disc, and an auxiliary handle, with the supporting plate disposed on both sides of the upper surface of the fixed base plate, and the supporting cylinder installed on the inner surface of the supporting plate.

[0011] Furthermore, the support cylinder is threadedly connected to the inner side of the support plate with a threaded support rod, and a limit plate is installed at the inner end of the threaded support rod, while an auxiliary handle is provided at the outer end of the threaded support rod.

[0013] This utility model provides a deformation-resistant tooling for testing the airtightness of new energy battery casings, which has the following beneficial effects:

[0014] 1. This utility model incorporates an adjustment component, which includes a fixed support frame, a support cross plate, a movable frame, a support connecting plate, a fixed threaded hole, a fixing bolt, a hydraulic push rod, and a limiting plate. In use, the new energy battery casing is placed on the tooling fixing seat. The movable frame slides along the surface of the support cross plate, and the movable frame drives the support connecting plate to move along the inner side of the support cross plate. The distance between the two sets of support connecting plates is adjusted as needed, thereby moving the hydraulic push rod and the limiting plate to the appropriate position. The fixed bolt is threaded into the fixed threaded hole to fix the movable frame to the support cross plate. The hydraulic push rod is activated, causing it to move the limiting plate downwards, thus fixing the new energy battery casing. This allows the device to fix the new energy battery casing, and the spacing of the fixing mechanism can be adjusted according to the actual size of the new energy battery casing, making it suitable for testing casings of different sizes.

[0015] 2. This utility model incorporates a limiting component, which includes a support plate, a support cylinder, a threaded support rod, a limiting disc, and an auxiliary handle. The limiting component also includes a fixing element and a fixing clamp. In use, the threaded support rod is rotated via the auxiliary handle, causing it to move left and right along the inner side of the support plate and support cylinder.

Simultaneously, the fixing clamp is rotated along the inner side of the fixing element, further limiting the front and rear ends of the new energy battery casing. This allows the device to further limit the new energy battery casing, maintaining stability during the testing process. Attached Figure Description

The fixed support frame 301 is located on the front of the upper surface of the fixture fixing base 1. At the rear end, a support plate 302 is provided on the upper part of the inner side of the fixed support frame 301. Two sets of support plates 302 are symmetrically arranged, and a movable frame 303 is slidably connected to the surface of the support plate 302. A support connecting plate 304 is installed on the inner surface of the movable frame 303. Fixed threaded holes 305 are opened on the surfaces of the support plate 302 and the movable frame 303, and fixed bolts 306 are threadedly connected to the inner side of the fixed threaded holes 305. A hydraulic push rod 307 is installed on the upper side of the support connecting plate 304, and a limit plate 308 is provided at the bottom of the hydraulic push rod 307.

[0023] The specific operation is as follows: When in use, place the new energy battery shell on the tooling fixing seat 1. The movable frame 303 is slidably connected to the surface of the support plate 302. The movable frame 303 drives the support connecting plate 304 to move along the inner side of the support plate 302. Adjust the distance between the two sets of support connecting plates 304 as needed, thereby driving the hydraulic push rod 307 and the limiting plate 308 to move to a suitable position. Fix the movable frame 303 to the support plate 302 by connecting the fixing bolt 306 to the threaded connection inside the fixing threaded hole 305. Start the hydraulic push rod 307 to drive the limiting plate 308 to move downward, and fix the new energy battery shell through the limiting plate 308.

[0024] Please refer to Figures 3 to 4 The tooling fixture 1 has a support base frame 4 installed on its lower surface, and the support base frame 4 has an anti-slip pad 5 on its lower surface. The tooling fixture 1 and the fixed base plate 2 are an integrated structure that is tightly connected. The fixed base plate 2 has a limiting component 6 for limiting the position. The limiting component 6 includes a support plate 601, a support cylinder 602, a threaded support rod 603, a limiting plate 604, and an auxiliary handle 605. The support plate 601 is located on both sides of the upper surface of the fixed base plate 2. The support cylinder 602 is installed on the inner surface of the support plate 601. The support cylinder 602 is threadedly connected to the inner side of the support plate 601 with a threaded support rod 603. The limiting plate 604 is installed at the inner end of the threaded support rod 603. The auxiliary handle 605 is provided at the outer end of the threaded support rod 603. The limiting component 6 also includes a fixing member 606 and a fixing clamp 607. The fixing member 606 is installed at both the front and rear ends of the upper surface of the fixed base plate 2. The fixing member 606 is rotatably connected to the surface of the fixing member 606.

[0025] The specific operation is as follows: When in use, rotate the threaded support rod 603 by using the auxiliary handle 605, so that the threaded support rod 603 moves left and right along the inner side of the support plate 601 and the support cylinder 602. The threaded support rod 603 drives the limiting plate 604 to move left and right until the surface of the limiting plate 604 is limited to both sides of the new energy battery shell. At the same time, rotate the fixing clamp 607, so that the fixing clamp 607 rotates along the inner side of the fixing member 606, so that the fixing clamp 607 further limits the front and rear ends of the new energy battery shell.

[0026] In summary, as Figures 1 to 4 As shown, this anti-deformation fixture for airtightness testing of new energy battery casings, when in use, first, places the new energy battery casing on the fixture fixing base 1. The movable frame 303 slides on the surface of the supporting horizontal plate 302, causing the supporting connecting plate 304 to move along the inner side of the supporting horizontal plate 302 via the movable frame 303. The distance between the two sets of supporting connecting plates 304 is adjusted as needed, thereby moving the hydraulic push rod 307 and the limiting plate 308 to a suitable position. The movable frame 303 is then fixed to the supporting horizontal plate 302 via the threaded connection between the fixing bolt 306 and the inner side of the fixing threaded hole 305. The process is then initiated. The hydraulic push rod 307 causes the limiting plate 308 to move downwards, thereby fixing the new energy battery casing. The threaded support rod 603 is rotated by the auxiliary handle 605, causing it to move left and right along the inner side of the support plate 601 and the support cylinder 602. The threaded support rod 603 causes the limiting plate 604 to move left and right until the surface of the limiting plate 604 is limited to both sides of the new energy battery casing. At the same time, the fixing clamp 607 is rotated, causing it to rotate along the inner side of the fixing member 606, thereby further limiting the front and rear ends of the new energy battery casing.
