Description

Technical Field

[0001] The present invention belongs to the technical field of guide structures, and more specifically, particularly relates to a precision guide structure for airtight testing. Background Art

[0002] In the field of industrial production and manufacturing, cavities are widely used as a common key component in many industries such as machinery, electronics, and chemicals to facilitate users to achieve specific functions, such as storing and transmitting substances or energy. However, the cavities on the market may have tiny pores or poor sealing after completion. If the completed cavity is not tested for airtightness, leakage problems are likely to occur, which will affect the quality and safety of the product, and further affect the entire production process and the performance of the final product. In order to avoid such situations, airtight test fixtures are used for airtightness testing; however, existing airtight test fixtures usually use single-piece guide mechanisms. During the mold closing process, due to machining tolerance or assembly clearance, it is easy to produce guiding deviation, resulting in misalignment and extrusion of the cavity sealing ring, causing the local deformation of the sealing ring to exceed the elastic limit, reducing the sealing reliability and accelerating the aging of the sealing ring; in addition, the existing airtight inspection fixture usually adopts an integral sealing block to simultaneously bear the sealing of the main cavity seal and the waterway auxiliary, lacking effective partition sealing and stable guiding structure. If the cavity and waterway cannot be sealed independently and stably, it is easy to be affected by the dimensional fluctuation of the sealing surface, resulting in unstable tooling sealing, causing misjudgment in the airtight production process, and reducing the reliability and accuracy of traditional devices.

The following examples are used to illustrate the technical solutions of the present invention, but cannot be used to limit the protection scope of the present invention.

[0032] Example:

[0033] like Figures 1 to 4 As shown, the present invention provides a precise guide structure for airtight testing, including a first fixing plate 11. The first fixing plate 11 can provide a stable bottom support for the entire structure, so that the user can safely perform subsequent operations, thereby improving the stability of the structure. A positioning plate 12 is provided on the top of the first fixing plate 11, and a cavity workpiece 13 is detachably connected to the top of the positioning plate 12. The user can use the positioning plate 12 to accurately locate the installation position of the cavity workpiece 13, so that the device can ensure the accuracy of the installation of the cavity workpiece 13, improve the installation accuracy, and enhance the user's safety in installation. In order to facilitate the installation operation, a first clamping block 14 and a second clamping block 15 are arranged between the cavity workpiece 13 and the positioning plate 12. The arrangement of the first clamping block 14 and the second clamping block 15 can enhance the stability of the connection between the cavity workpiece 13 and the positioning plate 12, so that the user can avoid the displacement of the cavity workpiece 13 during work, thereby improving the reliability of the device.

[0034] like Figure 2As shown, multiple groups of guide components are arranged between the second fixed plate 16 and the first fixed plate 11, which can guide the relative movement between the second fixed plate 16 and the first fixed plate 11, so that the user can ensure the accuracy of the movement of the two, and improve the guiding performance of the device. The guide component includes a first limit rod 201, and the top of the first limit rod 201 is arranged in the second fixed plate 16. The user can limit the movement range of the second fixed plate 16 through the first limit rod 201, so that the device can avoid excessive movement of the second fixed plate 16, thereby improving the operating safety of the device. A second limit rod 202 is arranged below the first limit rod 201, and the bottom of the second limit rod 202 is clamped in the first fixed plate 11, which can further enhance the restriction and guidance of the movement of the second fixed plate 16, so that the user can ensure the smooth movement of the second fixed plate 16, and improve the working stability of the device.

[0035] An adjusting head 203 is threadedly connected to the bottom of the first limiting rod 201. The user can flexibly adjust the length of the first limiting rod 201 through the adjusting head 203, so that the device can adapt to different work requirements and improve the applicability of the device. A plurality of groups of limiting bolts 204 are arranged between the adjusting head 203 and the first limiting rod 201, and the plurality of groups of limiting bolts 204 are all sleeved on the adjusting head 203. Through the arrangement of the plurality of groups of limiting bolts 204, the connection between the adjusting head 203 and the first limiting rod 201 can be stabilized, so that the user can perform the adjustment operation with confidence, thereby improving the reliability of the device.

[0036] like Figure 2 and Figure 7 As shown, the guide assembly also includes a fixing seat 301, which is detachably connected to the first fixing plate 11, and a guide column 302 is arranged in the fixing seat 301, and a first fixing block 303 is arranged below the guide column 302, and the first fixing block 303 is clamped in the fixing seat 301.

The guiding and limiting are separated through this structure, thereby improving the tooling test conditions.

[0038] like Figures 2 to 6As shown, a cavity sealing block 17 is provided between the second fixing plate 16 and the cavity workpiece 13.

Two groups of waterway sealing blocks 18 and limiting blocks 19 are respectively provided between the cavity sealing block 17 and the cavity workpiece 13. The user can enhance the sealing effect of the waterway part through the two groups of waterway sealing blocks 18, so that the device can avoid leakage problems in the waterway and improve the sealing reliability of the device. By setting the limiting blocks 19, the moving range of the components can be limited, so that the user can ensure the structural stability of the device and improve the operating safety of the device. The cavity sealing block 17 A fixing component is arranged on the top, and the fixing component includes multiple groups of compression springs 401 and multiple groups of guide rods 402. The second fixing plate 16 and the two groups of waterway sealing blocks 18 are connected to the cavity sealing block 17 through multiple groups of compression springs 401 and multiple groups of guide rods 402. The limit block 19 is arranged in the cavity sealing block 17. Through this structure, two relatively independent sealing surfaces can be formed. Different compression springs 401 are used to provide uniform compression force, so that the device can ensure the tightness of the seal and improve the sealing effect of the device. Through the arrangement of multiple groups of guide rods 402, the moving direction of the component can be accurately guided, so that the user can ensure the accuracy of the component installation and improve the installation accuracy of the device.

[0039] like Figure 3 As shown, multiple groups of air pumps 20 are arranged on the periphery of the cavity workpiece 13, which can provide a stable air source for the airtight test, so that the user can efficiently perform the airtight test, thereby improving the efficiency of the test; multiple groups of air pumps 20 are all provided with an installation kit 21, through which the user can firmly install the air pump 20, so that the device can prevent the air pump 20 from loosening during operation, thereby improving the working stability of the air pump 20; multiple groups of installation kits 21 are respectively arranged on the first fixed plate 11 and the second fixed plate 16, so that the installation positions can be reasonably allocated, so that the user can optimize the structural layout of the device, thereby improving the space utilization rate of the device; one end of the multiple groups of air pumps 20 are respectively sealed and connected to the cavity workpiece 13, thereby ensuring the leakage-free transmission of gas, thereby enabling the user to obtain accurate airtight test results, thereby improving the accuracy of the airtight test.

[0040] like Figure 2 and Fig. 9As shown, a sealing component is provided on the cavity workpiece 13, and the sealing component can effectively ensure the sealing of the airtight test, so that the user can obtain reliable test results and improve the accuracy of the airtight test. The sealing component includes a first sealing ring 101, and the bottom of the first sealing ring 101 is clamped in the positioning plate 12, and the top of the first sealing ring 101 is arranged in the cavity workpiece 13. The user can use the first sealing ring 101 to achieve the seal between the cavity workpiece 13 and the positioning plate 12, so that the device can prevent gas leakage from the connection, thereby improving the sealing performance of the device. A second sealing ring 102 is clamped between the cavity workpiece 13 and the cavity sealing block 17, which can ensure the firmness and sealing of the waterway sealing block 18 during installation, so that the user does not need to worry about its falling off and leakage during the test, thereby improving the stability of the device.

[0041] like Figures 8 to 11 As shown, the bottoms of the two groups of water channel sealing blocks 18 are respectively clamped in the cavity workpiece 13, which can effectively seal the water channel part, so that the user can avoid leakage problems in the water channel, and improve the overall sealing effect of the device. A third sealing ring 103 is clamped between the cavity workpiece 13 and the two groups of water channel sealing blocks 18. The first sealing ring 101, the second sealing ring 102 and the two groups of third sealing rings 103 are all made of rubber material, and can utilize the good elasticity and sealing properties of rubber, so that the user can obtain excellent sealing performance, thereby improving the airtight test quality of the device.

[0042] The specific usage and function of this embodiment are as follows:

[0043] When using the airtight test precision guide structure, first place the cavity workpiece 13 on the positioning plate 12, and achieve precise positioning through the positioning plate 12, then use the first clamping block 14 and the second clamping block 15 to enhance the stability of the connection between the cavity workpiece 13 and the positioning plate 12, and then connect the second fixing plate 16 to the first fixing plate 11 through the guide assembly. In this process, the first limiting rod 201 and the second limiting rod 202 limit and guide the relative movement of the two to ensure the accuracy and stability of the movement. The user can adjust the length of the first limiting rod 201 through the adjustment head 203 to adapt to different work requirements. At the same time, multiple groups of limiting bolts 204 ensure the reliability of adjustment. The guide column 302 and its related components further ensure the accuracy and stability of the guide. The inner bushing 304 reduces the wear of the guide column 302, the spring and the guide ball make the movement smoother and smoother, and the fixed sleeve 305 and its related components enhance the stability and safety of the structure.
