Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and more specifically, to an airtightness leak detection tooling. Background Technology

[0002] The airtightness test procedure includes the following steps: anti-blocking of the upper and lower holes of the motor stator, anti-leakage and blockage of the power cord, filling of the brake hole of the housing, and synchronous leak testing.

[0003] The stator airtightness test and motor waterproof sealing process are crucial steps in the servo stator manufacturing process, directly impacting the performance and reliability of the servo motor during operation. Airtightness testing is prone to misjudgments due to the significant gap between the tooling and the product, leading to various airtightness issues. Failure to address these issues promptly can result in a large number of defective products, significantly impacting overall quality.

[0004] In actual operation, the operator places the rubber pad on top of the product, places the product on the airtight pad, presses the pneumatic button to press down the product, and gas will enter the product. After the gas is injected, a brush dipped in water is used to observe whether there are air bubbles.

[0005] However, the above operation process has the following problems: there is a risk that the rubber pad may fall off when the product is placed; if the rubber pad is placed manually, it may be deformed due to prolonged pressing, and the product may slip and fall and get injured; manual leak detection is inefficient and may cause equipment failure. Summary of the Invention

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide an airtight leak detection fixture, which can realize the positioning of the product by placing it in the fixture, starting the buttons with both hands, and controlling the cylinder to press down the fixture to detect airtightness.

[0007] To solve the above problems, this utility model adopts the following technical solution: an airtight leak detection fixture, including a fixture body, a working platform fixedly connected to the upper end of the fixture body, a fixed frame fixedly connected to the upper end of the working platform, four evenly distributed cylinders embedded in the upper end of the fixed frame, a pressure block fixedly connected to the power output end of the cylinders, four evenly distributed positioning blocks fixedly connected to the upper end of the fixture body, the positioning blocks being located below the pressure blocks and corresponding to the pressure blocks, a sealing column being provided between the pressure blocks and the positioning blocks, a product being placed inside the sealing column, and a sensor being fixedly installed at the outer end of the sealing column. This allows the product to be placed into the fixture for positioning, and the fixture to be pressed down by the cylinders controlled by both hands using a start button, thereby detecting airtightness.

[0008] Furthermore, a groove is chiseled at the bottom of the pressure block, and an embedded sealing gasket is fixedly connected to the bottom of the groove. The embedded sealing gasket is located on the outside of the product and is in contact with the product. By setting the groove and the embedded sealing gasket, the sealing between the pressure block and the product can be improved, thereby improving the accuracy of the product airtightness test.

[0009] Furthermore, the upper end of the positioning block is chiseled with an annular groove. By setting the annular groove, the product can be easily placed in the annular groove, which can improve the stability of the clamping block and the positioning block in holding the sealing column.

[0010] Furthermore, the upper end of the positioning block is chiseled with multiple first air leakage holes, and the annular groove is located outside the first air leakage holes. By setting the first air leakage holes, the exhaust function can be achieved, reducing the possibility of damage caused by excessive air pressure inside the product.

[0011] Furthermore, the sealing column is provided with an embedded block, which is located inside the product and in contact with the product. The upper end of the embedded block is drilled with multiple evenly distributed second vent holes. By setting the embedded block, the stability of the product inside the sealing column can be improved. By setting the second vent holes, the gas inside the product can be discharged in time, reducing the possibility of damage due to excessive gas pressure inside the product.

[0012] Furthermore, a sealing ring is fixedly connected to the outer end of the embedded block. By setting the sealing ring, the sealing performance between the embedded block and the product can be further improved, the possibility of air leakage between the sealing column and the product can be reduced, thereby improving the accuracy of air tightness testing.

[0015] (3) An annular groove is chiseled at the upper end of the positioning block. By setting the annular groove, the product can be conveniently placed in the annular groove, which can improve the stability of the pressure block and positioning block in clamping the sealing column.

[0016] (4) Multiple first air leakage holes are drilled at the upper end of the positioning block. The annular groove is located outside the first air leakage holes. By setting the first air leakage holes, the exhaust function can be played, reducing the possibility of damage caused by excessive air pressure inside the product.

[0017] (5) An embedded block is provided inside the sealing column. The embedded block is located inside the product and is in contact with the product. Multiple evenly distributed second air leakage holes are drilled at the upper end of the embedded block. By setting the embedded block, the stability of the product inside the sealing column can be improved.
