Description

Technical Field

[0001] The utility model relates to the technical field of new energy heat exchangers, in particular to a special fixture for measuring the load of a liquid cooling plate. Background Art

[0002] When testing the flatness of a battery pack liquid cold plate, it is usually necessary to simulate the actual packing load state, that is, the cold plate is measured under load. Depending on the different packing conditions, some cold plates require the load to be in the module area, while others require the load to be in the installation area between the cold plate and the box.

[0003] In the existing technology, when operators use standard load blocks to load products, they need to frequently move them, which is labor-intensive and has low measurement efficiency. In addition, the load position relies on visual judgment, which is inaccurate and affects the stability of the flatness measurement data. Utility Model Content

[0004] The purpose of the present utility model is to provide a special fixture for measuring the load of a liquid cooling plate, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a special fixture for measuring the load of a liquid cooling plate, comprising a workbench, a plurality of loading mechanisms symmetrically provided on both sides of the end surface of the workbench, a product being pressed between the loading mechanisms and the workbench, and compression strips symmetrically provided on both sides of the workbench.

[0006] Further optimized, the load mechanism includes a mounting plate fixedly arranged at the lower ends of both sides of the workbench, a telescopic cylinder is provided at the lower end of the mounting plate, a fixed block is provided at the telescopic end of the telescopic cylinder connected thereto, a hinge assembly is provided on the fixed block connected thereto, and a pressure block is provided at the upper end of the hinge assembly away from the fixed block.

[0007] For further optimization, a through hole is provided on the end surface of the mounting plate, and the telescopic end of the telescopic cylinder passes through the through hole and is connected to the fixed block.

[0008] For further optimization, a cylindrical shaft seat is provided on one side of the through hole, and the upper end of the cylindrical shaft seat is rotatably connected to the hinge assembly.

[0009] In a further optimization, the pressing block is fixedly connected to the pressing strip.

[0010] Further optimized, the hinge assembly is movably connected to the fixed block and the pressing block respectively.

[0011] Beneficial effects

[0012] The special fixture for liquid cooling plate load measurement provided by the utility model reduces the labor intensity of personnel during product measurement, improves the accuracy of load area position, can accurately analyze product flatness, and provide theoretical support for subsequent process improvement and yield improvement. The load mechanism has a short force arm and a small motion trajectory range, which is convenient for product removal and placement, and the output load force value is stable. The force arm of the cylinder source thrust is almost equal to the force arm of the pressure block head position, which can accurately and quickly control the load force within the design requirement value.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] Example

[0020] like Figure 1-5 As shown, a special fixture for measuring the load of a liquid cooling plate includes a workbench 4, a plurality of loading mechanisms 1 are symmetrically provided on both sides of the end surface of the workbench 4, a product 3 is pressed between the loading mechanism 1 and the workbench 4, and pressing strips 2 are symmetrically provided on both sides of the workbench 4.

[0021] In this embodiment, the load mechanism 1 includes a mounting plate 1-2 fixedly arranged at the lower ends of both sides of the workbench 4, a telescopic cylinder 1-1 is provided at the lower end of the mounting plate 1-2, a fixed block 1-5 connected to the telescopic end of the telescopic cylinder 1-1 is provided, a hinge assembly 1-3 connected to the fixed block 1-5 is provided on the fixed block 1-5, and a pressure block 1-4 is provided at the upper end of the hinge assembly 1-3 away from the fixed block 1-5.

[0022] A through hole is provided on the end surface of the mounting plate 1-2, and the telescopic end of the telescopic cylinder 1-1 passes through the through hole and is connected to the fixing block 1-5.

[0023] A cylindrical shaft seat 1-6 is provided on one side of the through hole, and the upper end of the cylindrical shaft seat 1-6 is rotatably connected to the hinge assembly 1-3.

[0024] The pressing blocks 1 - 4 are fixedly connected to the pressing strip 2 .

[0025] The hinge assembly 1-3 is movably connected to the fixing block 1-5 and the pressing block 1-4 respectively.

[0026] Pressure Description: Figure 5 As shown, the moment arm for cylinder thrust F1 is 45mm, similar to the moment arm for pressure F2, which is 44.39mm. Analyzing this entire mechanism, the input and output forces are only F1 and F2, respectively. The entire system maintains balance (F1≈F2, meaning the torques are equal and there is no force loss). When the product requires a specific load pressure, simply adjust the air source pressure to achieve the required cylinder thrust. This eliminates unnecessary adjustments and calculations, making adjustments easy and the output force stable.

[0027] The load-balancing and tightening strips must be made of materials with good rigidity and should not deform when a load is applied;

[0028] When installing a single set of load-sharing mechanisms, ensure that the installation height is consistent (two load-sharing mechanisms share one clamping bar) to avoid bending and deformation of the clamping bar due to inconsistent cylinder strokes.

[0029] Every two sets of loading mechanisms 1 and a pressing bar 2 constitute a load-balancing mechanism. The product 3 is placed on the workbench 4. The cylinder 1-1 provides a pressure source. The fixed block 1-5 moves upward under the push of the cylinder 1-1. Under the conversion action of the hinge assembly 1-3, the pressing block 1-4 drives the pressing bar 2 to move to the load area of ​​the product 3 and applies vertical downward pressure there.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
