Description

Technical Field

[0001] The present application relates to the technical field of airtightness detection, and in particular to an airtightness detection sealing tool and a detection system. Background Art

[0002] In the production process of various device shells, in order to ensure the sealing performance of the device shell, the device shell needs to be tested for air tightness. Since the device shell usually has multiple through holes for installing parts, before testing, the multiple through holes need to be blocked by a sealing tool with a blocking piece, so as to form a closed cavity inside the device shell, and then compressed gas is passed into the cavity of the device shell for air tightness testing.

[0003] In order to press the sealing part against the through hole of the device shell, the prior art usually uses a cylinder and other components to connect with the sealing part to form an integral sealing tooling, and then presses the sealing part against the outer surface of the device shell through the cylinder, so that the sealing part seals the through hole from the outside of the device shell.

[0004] However, when the actual assembly state of the product is to assemble parts from the inside of the chamber to seal, the sealing requirements of the airtightness test need to be consistent with the actual assembly state of the product, that is, the plugging parts need to seal the through holes from the inner surface of the device shell, otherwise the consistency of the test results and the actual assembly state cannot be guaranteed. When the volume of the internal chamber of the device shell is relatively narrow, the oil cylinder and the plugging parts cannot be arranged inside the device shell at the same time, resulting in limited application scenarios of the integral sealing tooling. Utility Model Content

[0005] One of the purposes of the present application is to provide an airtight detection sealing tool to solve the problem that when the sealing tool in the prior art is an integral structure, the tool structure is large in size and cannot be arranged inside the chamber of the device shell to achieve through-hole sealing from the inner side of the device shell; the second purpose is to provide a detection system.

[0006] In order to achieve the above purpose, the technical solution adopted in this application is as follows:

[0007] An airtight detection and sealing tool, comprising:

[0008] A driving module, wherein the driving module comprises a connected position adjustment component and a connecting component, and the position adjustment component drives the connecting component to move;

[0009] A plugging module, the plugging module comprises a plugging component, the plugging component has a connecting portion matching the connecting component, and the connecting component and the connecting portion are detachably connected.

[0010] According to the above technical means, since the connection between the connecting component and the connecting part is detachable, the driving module and the sealing module can be separated. When it is necessary to achieve sealing on the inner side of the workpiece to be measured, the smaller sealing module can be set on the inner side of the workpiece to be measured, and the driving module can be set on the outer side of the workpiece to be measured. The connecting component is then passed through the through hole of the workpiece to be measured and connected to the connecting part of the sealing component. The connecting component and the sealing component are driven by the position adjustment component, so that the sealing component is pressed against the surface to be sealed on the inner side of the through hole, thereby achieving sealing on the inner side of the workpiece to be measured, which is conducive to ensuring that the sealing state during the airtightness test is consistent with the actual assembly state of the product.

[0011] Furthermore, one end of the connecting component is connected to the position adjustment component, and the other end of the connecting component has a clamping portion, and the connecting portion is a clamping groove matched with the clamping portion.

[0012] According to the above technical means, the blocking component and the connecting component can be connected by snapping. Compared with other detachable connection methods, the time required for connection is shorter, which is conducive to the rapid disassembly and assembly between the driving module and the blocking module.

[0013] Furthermore, the connecting portion has a locking position and a releasing position, the locking position has a limiting structure matched with the clamping portion, and the position adjustment component drives the clamping portion to move between the locking position and the releasing position.

[0014] According to the above technical means, when the clamping part is in the locking position, the clamping part and the blocking component can be stably connected through the limiting structure to prevent the clamping part from being disengaged from the connecting part, thereby achieving locking between the driving module and the blocking module. When the clamping part is in the releasing position, the clamping part can be disengaged from the connecting part, thereby achieving separation of the connecting component and the blocking component.

[0015] Further, the connecting portion has a gourd hole and a concave cavity connected to the gourd hole, the small hole end of the gourd hole is configured as the locking position, and the large hole end of the gourd hole is configured as the releasing position;

[0016] The clamping portion has a first shaft segment and a second shaft segment arranged in sequence along its length direction, the size of the first shaft segment is smaller than the size of the second shaft segment, the locking position is matched with the first shaft segment, the concave cavity is matched with the second shaft segment, and the second shaft segment passes through the release position and is embedded in the concave cavity.

[0017] According to the above technical means, when the clamping part moves in the gourd hole, the clamping part can be matched with the locking position or the releasing position. The first shaft segment and the second shaft segment form a stepped shaft structure at the free end of the connecting component, and the small hole end of the gourd hole is connected to the concave cavity to form a T-shaped structure, which matches the stepped shaft structure formed by the connection of the first shaft segment and the second shaft segment. Since the size of the second shaft segment is larger than the size of the small hole end of the gourd hole, when the connecting component applies an axial pulling force to the blocking component, the second shaft segment cannot be disengaged from the connecting part along the axial direction of the connecting component, and the locking between the clamping part and the connecting part can be achieved.

[0018] Furthermore, the blocking component includes a blocking member and a sealing member, the sealing member is arranged along the circumference of the blocking member, and the connecting portion is arranged on the blocking member.

[0019] According to the above technical means, the sealing member is arranged along the circumference of the plugging member, and can be used to abut against the surface to be sealed on the workpiece to be measured, and the sealing member is located outside the through hole, and the sealing member and the surface to be sealed are completely fitted together through the elastic deformation of the sealing member, thereby improving the sealing reliability between the plugging assembly and the surface to be sealed. The connecting portion is arranged on the plugging member, and is used to realize the connection between the plugging member and the connecting assembly.

[0020] Furthermore, the blocking member has a blocking surface for abutting against the workpiece to be measured, the sealing member is arranged along the circumference of the blocking surface, and the connecting portion is arranged on the blocking surface.

[0021] According to the above technical means, the blocking surface is arranged opposite to the surface to be sealed, and the sealing member is arranged along the circumference of the blocking surface, which can be used to achieve circumferential sealing between the blocking surface and the surface to be sealed. Since the blocking surface and the through hole on the surface to be sealed are arranged opposite to each other, the connecting part is arranged on the blocking surface, so that the clamping part passes through the through hole and is connected to the connecting part on the blocking surface.

[0022] Furthermore, the position adjustment component includes a first sliding component and a second sliding component, the first sliding component drives the second sliding component to slide along a first direction, and the second sliding component drives the connecting component to slide along a second direction, and the first direction is perpendicular to the second direction.

[0023] According to the above technical means, the first sliding component drives the second sliding component to slide along the first direction, thereby realizing the movement of the connecting component between the locking position and the releasing position. The second sliding component drives the connecting component to slide along the second direction, so that the connecting component drives the blocking component to press against the surface to be sealed. The first direction is perpendicular to the second direction, so that the airtight detection sealing tool can first realize the locking action and then realize the sealing pressing action, which can avoid the occurrence of mis-locking and improve the working reliability of the airtight detection sealing tool.

[0024] Furthermore, the position adjustment assembly also includes a guide assembly, the length direction of the guide assembly is parallel to the first direction, and the second sliding assembly is connected to the guide assembly.

[0025] According to the above technical means, the second sliding component can drive the connecting component to slide stably along the first direction, so that the clamping part can move smoothly and accurately between the release position and the locking position, which is conducive to achieving accurate connection or separation between the connecting component and the blocking component.

[0026] A detection system includes the above-mentioned airtight detection sealing tooling, and also includes a base, the blocking module is movably arranged on the base, the blocking module includes a reset member, the reset member is connected to the base, and the reset member always has a tendency to keep the blocking module away from the driving module.

[0027] According to the above technical means, the plugging module can be initially positioned through the connection between the base and the plugging module, which facilitates the connection between the plugging module and the connecting component, without the need to manually grasp and position the plugging module inside the workpiece to be measured. The reset member always has a tendency to move the plugging module away from the driving module. When the clamping part moves to the release position of the connecting part, the limiting effect of the clamping part on the plugging part is released, and the plugging part can be moved away from the driving module and the surface to be sealed under the action of the reset member, which is conducive to the rapid separation of the plugging part and the connecting component.

[0028] Furthermore, the blocking module is connected to the slide rail assembly, and the length direction of the slide rail assembly is perpendicular to the surface to be sealed of the workpiece to be measured.

[0029] According to the above technical means, when the connecting assembly pulls the sealing part to overcome the elastic force of the reset part and move, the sliding rail assembly can be used to guide the movement of the sealing part so that the sealing part is vertically abutted against the surface to be sealed, applying uniform pressure to the surface to be sealed, thereby achieving uniform sealing of the through holes on the surface to be sealed.

[0030] Furthermore, the detection system also includes a workpiece fixture for fixing the workpiece to be measured on the base.

[0031] According to the above technical means, the position of the workpiece to be measured on the base can be ensured to be fixed, and when the connecting component applies force to the blocking component, the workpiece to be measured is prevented from moving relative to the base, thereby causing sealing failure.

[0032] Beneficial effects of this application:

[0033] (1) The airtight detection sealing tool of the present application is suitable for sealing the shell of any device, especially when it is necessary to seal the inner side of the workpiece to be measured. Since the driving module and the sealing module are detachably connected, the two can be separated, and the sealing module and the driving module can be respectively arranged on the inner and outer sides of the workpiece to be measured, and then the connection between the sealing module and the driving module is realized through the connecting component and the connecting part, so that the driving module can drive the sealing component to abut against the inner side of the workpiece to be measured, thereby realizing the inner sealing of the workpiece to be measured.

[0034] (2) The airtight detection sealing tooling in the present application is a detachable structure, and a smaller sealing module can be set on the inner side of the workpiece to be measured, and the driving module can be set on the outer side of the workpiece to be measured. This is conducive to the layout of the airtight detection sealing tooling, and is conducive to the inner side sealing and airtightness detection of the workpiece to be measured when the internal cavity of the workpiece to be measured is narrow.

DETAILED DESCRIPTION

[0046] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0047] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0048] This embodiment proposes an airtight detection and sealing tool, including a driving module and a blocking module, such as Figure 1 The driving module includes a connected position adjustment component 1 and a connecting component 2, and the position adjustment component 1 drives the connecting component 2 to move, so as to achieve relative position adjustment between the connecting component 2 and the blocking module or the workpiece 6 to be measured.

[0049] The blocking module includes a blocking component 3, which has a connecting portion 311 matching the connecting component 2. The connecting component 2 and the connecting portion 311 are detachably connected. When it is necessary to block from the inner side of the workpiece 6 to be measured, the driving module and the blocking module can be separated due to the detachable connection between the driving module and the blocking module; then the blocking module is set on the inner side of the workpiece 6 to be measured, and the driving module is set on the outer side of the workpiece 6 to be measured; then the connecting component 2 is passed through the through hole 62 of the workpiece 6 to be measured and connected to the connecting portion 311 of the blocking component 3, and the connecting component 2 and the blocking component 3 are driven by the position adjustment component 1 to adjust the relative position between the blocking component 3 and the workpiece 6 to make the blocking component 3 pressed against the sealing surface 61 on the inner side of the through hole 62 to achieve the blocking of the inner side of the through hole 62.

[0050] It should be noted that since the airtight detection sealing tooling in the present application includes a separable driving module and a sealing module, the sealing module is relatively small in size and can be set in the narrow chamber 63 of the workpiece 6 to be measured, while the driving module with a larger structural size can be set on the outside of the workpiece 6 to be measured, which is conducive to the overall layout of the airtight detection sealing tooling and the inner sealing of the workpiece 6 to be measured, and is conducive to ensuring that the sealing state during the airtightness test is consistent with the actual assembly state of the product.

[0051] It should be noted that the airtight detection sealing tool of the present application can set the blocking module on the inner side of the workpiece 6 to block, or can set the blocking module on the outer side of the workpiece 6 to block, and the position of the connection part 311 can be set according to the use scenario. For example, when the blocking component 3 is set on the inner side of the workpiece 6 to be measured, the connection part 311 is set on the side of the blocking component 3 close to the workpiece 6 to be measured; when the blocking component 3 is set on the outer side of the workpiece 6 to be measured, the connection part 311 is set on the side of the blocking component 3 away from the workpiece 6 to be measured.

[0052] It should be noted that the airtight detection sealing tool in the present application can be used to block the through hole 62 of any device housing. For the convenience of description, in the following embodiments, the electronic control housing is described as the workpiece 6 to be tested. Figure 2 and Figure 3 Since the height of the workpiece 6 to be measured is relatively small and the internal chamber 63 corresponding to the surface 61 to be sealed is narrow, the driving module and the sealing module cannot be arranged as a whole inside the chamber 63 of the workpiece 6 to be measured, and the actual assembly state of the through hole 62 on the workpiece 6 to be measured is to achieve sealing by assembling parts on the inner side of the workpiece 6 to be measured. Therefore, it is necessary to set the sealing module inside the chamber 63 and the driving module outside the chamber 63, and to achieve the sealing of the surface 61 to be sealed where the through hole 62 is located by connecting the driving module and the sealing module.

[0053] In the above embodiments, the detachable connection between the connecting component 2 and the connecting part 311 can be achieved by bolt connection, threaded connection or clamping, but compared with the clamping method, the connection time required for bolt connection and threaded connection is longer, which is not conducive to the rapid disassembly and assembly between the connecting component 2 and the blocking component 3.

[0054] In some preferred embodiments of this application, please refer to Figure 1 and Figure 4 One end of the connecting component 2 is connected to the position adjustment component 1 to adjust the position of the connecting component 2. The other end of the connecting component 2 has a clamping portion 21, and the connecting portion 311 is a clamping groove matched with the clamping portion 21, so that the blocking component 3 and the connecting component 2 can be connected by clamping.

[0055] In the above embodiment, if the clamping force between the connecting portion 311 and the clamping portion 21 is smaller than the pulling force applied by the connecting component 2 to the sealing component 3 during sealing, the clamping portion 21 may be at risk of detaching from the connecting portion 311, which may easily cause the sealing component 3 to fall off, thereby resulting in sealing failure.

[0056] In order to solve the above problems, in some embodiments of the present application, please refer to Figure 4 , Figure 5 and Figure 6 The connection part 311 has a locking position 3111 and a release position 3112. The locking position 3111 has a limiting structure matched with the clamping part 21. When the clamping part 21 is located at the locking position 3111, the limiting structure can realize a stable connection between the clamping part 21 and the blocking component 3. When the clamping part 21 is located at the release position 3112, the clamping part 21 can be disengaged from the connection part 311, realizing the separation of the connection component 2 and the blocking component 3. The position adjustment component 1 drives the clamping part 21 to move between the locking position 3111 and the release position 3112, thereby realizing the locking or separation between the connection component 2 and the blocking component 3. After the connection component 2 and the blocking component 3 are locked, the position adjustment component 1 can further drive the connection component 2 and the blocking component 3, so that the blocking component 3 blocks the through hole 62 on the sealing surface 61.

[0057] It should be noted that the structural dimensions of the locking position 3111 are smaller than those of the releasing position 3112, and the locking position 3111 has a limiting effect on the clamping portion 21, which can prevent the clamping portion 21 from escaping from the locking position 3111. The releasing position 3112 has no limiting effect on the clamping portion 21, and the clamping portion 21 can smoothly enter and exit the connecting portion 311 from the releasing position 3112.

[0058] In some preferred embodiments of this application, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 The connecting portion 311 has a gourd hole and a concave cavity 3113 connected to the gourd hole. The small hole end of the gourd hole is configured as a locking position 3111, and the large hole end of the gourd hole is configured as a release position 3112; the clamping portion 21 has a first shaft segment 211 and a second shaft segment 212 arranged in sequence along its length direction. The size of the first shaft segment 211 is smaller than that of the second shaft segment 212. The locking position 3111 is matched with the first shaft segment 211, and the concave cavity 3113 is matched with the second shaft segment 212. The second shaft segment 212 passes through the release position 3112 and is embedded in the concave cavity 3113. A stepped shaft structure is formed at the free end of the connecting component 2 by the first shaft segment 211 and the second shaft segment 212. When the second shaft segment 212 passes through the release position 3112 and enters the concave cavity 3113, the first shaft segment 211 is arranged relative to the locking position 3111. When the position adjustment component 1 drives the connecting component 2 to move from the release position 3112 to the locking position 3111, the first shaft segment 211 enters the small hole end of the gourd hole (i.e., the locking position 3111), and the second shaft segment 212 moves in the concave cavity 3113. The small hole end is connected with the concave cavity 3113 to form a T-shaped structure, which matches the stepped shaft structure formed by the connection of the first shaft segment 211 and the second shaft segment 212. Since the size of the second shaft segment 212 is larger than the size of the small hole end of the gourd hole, when the connecting component 2 applies an axial pulling force to the blocking component 3, the second shaft segment 212 cannot be disengaged from the connecting portion 311 along the axial direction of the connecting component 2, and the locking between the clamping portion 21 and the connecting portion 311 can be achieved. At least part of the inner wall of the cavity 3113 is configured as a limiting structure for limiting the axial movement of the second shaft segment 212. Figure 4 , Figure 7 and Fig.10 shown.

[0059] It should be noted that the setting of the concave cavity 3113 can provide a housing cavity for the second shaft segment 212 and prevent the connection portion 311 from penetrating the blocking member 31, thereby preventing gas from leaking through the connection portion 311 during the air tightness detection process.

[0060] It should be noted that the first shaft section 211 and the second shaft section 212 can be cylindrical structures or prismatic structures, both of which can achieve the purpose of the present application. When the first shaft section 211 and the second shaft section 212 are cylindrical structures, the diameter of the first shaft section 211 is smaller than the diameter of the second shaft section 212.

[0061] In some embodiments of this application, please refer to Figure 5 and Figure 6The plugging assembly 3 includes a plugging member 31 and a sealing member 32. The sealing member 32 is arranged along the circumference of the plugging member 31. The sealing member 32 is used to abut against the surface to be sealed 61, and the sealing member 32 is located outside the through hole 62. Through the elastic deformation of the sealing member 32, the sealing member 32 and the surface to be sealed 61 are completely fitted, thereby improving the sealing reliability between the plugging assembly 3 and the surface to be sealed 61. The connecting portion 311 is arranged on the plugging member 31, and is used to realize the connection between the plugging member 31 and the connecting assembly 2.

[0062] In some embodiments of this application, please refer to Figure 5 and Fig.10 The blocking member 31 has a blocking surface 312 for contacting with the workpiece 6 to be measured. The blocking surface 312 is arranged opposite to the surface 61 to be sealed. The sealing member 32 is arranged along the circumference of the blocking surface 312, and can be used to achieve circumferential sealing between the blocking surface 312 and the surface 61 to be sealed. Since the blocking surface 312 is arranged opposite to the through hole 62, the connecting portion 311 is arranged on the blocking surface 312, so that the clamping portion 21 passes through the through hole 62 and is connected to the connecting portion 311 on the blocking surface 312. It is suitable for the use scenario where the blocking module is arranged on the inner side of the workpiece 6 to be measured, and the driving module is arranged on the outer side of the workpiece 6 to be measured.

[0063] It should be noted that when the blocking module and the driving module are both arranged on the outside of the workpiece 6 to be measured to achieve outer side blocking, the connection part 311 is arranged on the side of the blocking member 31 facing away from the blocking surface 312, so that the connection component 2 can apply thrust (or pressure) to the blocking component 3 through the connection part 311, so that the blocking surface 312 of the blocking member 31 moves toward the outer surface of the workpiece 6 to be measured, and the sealing member 32 abuts against the outer surface of the workpiece 6 to be measured. When the connection parts 311 are provided on both the front and back sides of the blocking member 31, the connection component 2 is connected to the connection parts 311 on different sides of the blocking member 31, so that the airtight detection sealing tool of the present application can be applied to a variety of use scenarios of outer side sealing or inner side sealing, which can expand the scope of application of the airtight detection sealing tool of the present application.

[0064] In some embodiments of the present application, the seal 32 is a sealing ring made of rubber or silicone. The sealing member 31 is provided with a mounting groove 313 for embedding the sealing ring. In order to ensure the reliability of the seal, the seal 32 is embedded in the mounting groove 313 to a greater depth. In order to facilitate the disassembly and assembly of the seal 32 in the mounting groove 313, one or more mounting positions 3131 are provided in the circumference of the mounting groove 313. Both sides of the mounting position 3131 have recessed areas for easy finger insertion, so that the seal 32 can be easily buckled out of the mounting groove 313. Figure 5 and Figure 6 shown.

[0065] In some embodiments of this application, please refer to Figure 1 and Figure 4 The position adjustment component 1 includes a first sliding component 11 and a second sliding component 12. The first sliding component 11 drives the second sliding component 12 to slide along the first direction, thereby realizing the movement of the connecting component 2 between the locking position 3111 and the releasing position 3112. The second sliding component 12 drives the connecting component 2 to slide along the second direction, so that the connecting component 2 drives the blocking component 3 to press against the surface to be sealed 61. The first direction is perpendicular to the second direction, so that the connecting component 2 of the airtight detection sealing tool can first realize the locking action along the first direction, and then realize the sealing action along the second direction, which can avoid the occurrence of mis-locking and improve the working reliability of the airtight detection sealing tool.

[0066] It should be noted that the first direction is the reciprocating movement direction from the release position 3112 to the locking position 3111, which can be a horizontal direction or a vertical direction. As a specific embodiment of the present application, the locking position 3111 and the release position 3112 are arranged in the horizontal direction, the first direction is also the horizontal direction, and the second direction is the axial direction of the connecting component 2, so that the connecting component 2 can apply force to the sealing member 31 along its axial direction.

[0067] In some embodiments of this application, please refer to Figure 1 and Figure 4 The position adjustment assembly 1 further includes a guide assembly 13, the length direction of which is parallel to the first direction, and the second sliding assembly 12 is connected to the guide assembly 13, so that the second sliding assembly 12 can drive the connecting assembly 2 to slide stably along the first direction, so that the clamping portion 21 can move smoothly and accurately between the release position 3112 and the locking position 3111, which is conducive to achieving accurate connection or separation between the connecting assembly 2 and the blocking assembly 3. Specifically, the guide assembly 13 includes a guide rail disposed on the support 14, and also includes a slider fixedly connected to the second sliding assembly 12, and the guide rail and the slider are slidably connected along the first direction.

[0068] In some embodiments of the present application, the driving module further includes a support 14 and a buffer assembly 15. The second sliding assembly 12 and the guide assembly 13 are both disposed on the support 14, and can be used to adjust the height position of the second sliding assembly 12 and the connecting assembly 2, so as to facilitate the alignment of the clamping portion 21 and the connecting portion 311 in the height direction. The support 14 is also provided with a buffer assembly 15, and the buffer end of the buffer assembly 15 is disposed opposite to the second sliding assembly 12, and can buffer the second sliding assembly 12, thereby preventing the clamping portion 21 from causing an impact on the connecting portion 311 during the sliding process along the first direction.

[0069] In some embodiments of the present application, the first sliding component 11 is also disposed on the support 14 , so that the driving module is connected as a whole, which facilitates overall movement according to the sealing position of the workpiece 6 to be measured.

[0070] It should be noted that the first sliding assembly 11 can be a linear module, a cylinder, a pneumatic cylinder, and a connecting rod mechanism, and the second sliding assembly 12 can be a cylinder and a pneumatic cylinder, and both can achieve the purpose of the present application. The piston rod of the second sliding assembly 12 is fixedly connected to the connecting end 22 of the connecting assembly 2, and can drive the connecting assembly 2 to reciprocate along the second direction.

[0071] It should be noted that in the above embodiment, if the workpiece 6 to be measured has a large opening, the operator can put his hand into the workpiece 6 to fix the blocking module, which is convenient for connecting the blocking module and the driving module on both sides of the workpiece 6 to be measured. However, when the installation position of the blocking module inside the workpiece 6 to be measured is narrow, it is not convenient to position the blocking module inside the workpiece 6 to be measured by hand, which is not conducive to achieving the connection between the connecting component 2 and the blocking component 3.

[0072] In order to solve the above problems, the present application also proposes a detection system, including the airtight detection sealing tool in the above embodiment, and the detection system also includes a base 4, and the workpiece 6 to be measured is arranged on the base 4, and the bottom end face 64 of the workpiece 6 to be measured is in contact with the upper surface of the base body 41. The plugging module is movably arranged on the base 4, and the plugging module can be initially positioned by the connection between the base 4 and the plugging module. After the clamping portion 21 extends into the connecting portion 311 and moves to the locking position 3111 for locking, the plugging module is driven to move relative to the base 4 through the connecting component 2, so that the plugging component 3 can abut against the inner side of the workpiece 6 to achieve sealing at the through hole 62. At this time, there is no need to manually grasp and position the plugging module inside the workpiece 6 to be measured.

[0073] It should be noted that when performing air tightness testing, the bottom end face 64 of the workpiece 6 to be tested and the base 4 can be sealed by means of sealant or sealing gasket to avoid gas leakage from the bottom end face 64 of the workpiece 6 to be tested during the air tightness test.

[0074] In some embodiments of this application, please refer to Figure 1 , Figure 4 and Fig.10 The blocking module includes a reset member 5, which is connected to the base 4. The reset member 5 always has a tendency to keep the blocking module away from the driving module. When the clamping portion 21 moves to the release position 3112 of the connecting portion 311, the limiting effect of the clamping portion 21 on the blocking member 31 is released, and the blocking member 31 can be moved away from the driving module and the surface to be sealed 61 under the action of the reset member 5, which is conducive to the rapid separation of the blocking member 31 and the connecting assembly 2. At the same time, a distance can be created between the blocking member 31 and the inner wall of the workpiece 6 to avoid interference between the blocking member 31 and the workpiece 6, making it easier to remove the workpiece 6 from the base 4.

[0075] It should be noted that the reset member 5 can be arranged on the front side of the blocking member 31, so that the reset member 5 abuts between the front side of the blocking member 31 and the base 4, as shown in FIG. Fig.10 As shown. The reset member 5 can also be arranged at the bottom of the blocking member 31, and is used to connect with the upper surface of the base 4. The purpose of the present application can be achieved by applying a pulling force away from the sealing surface 61 to the blocking member 31 to reset the blocking member 31. The reset member 5 can be an elastic member such as a spring or a spring sheet, and the number of the reset member 5 can be one or more, which is not limited here.

[0076] As a specific embodiment of the present application, the blocking member 31 is provided with a mounting portion 314 for embedding the reset member 5, and the base 4 is provided with a groove for mounting the blocking member 31, so as to achieve the alignment of the blocking member 31 and the bottom through hole 62 of the workpiece 6 to be measured in the height direction. The reset member 5 is embedded in the mounting portion 314, so that the two ends of the reset member 5 in the horizontal direction are respectively abutted against the mounting portion 314 and the side wall of the groove, as shown in FIG. Figure 4 and Fig.10 shown.

[0077] In some embodiments of this application, please refer to Figure 1 and Figure 4 The base 4 further includes a slide rail assembly 42, the plugging module is connected to the slide rail assembly 42, and the length direction of the slide rail assembly 42 is perpendicular to the surface 61 to be sealed of the workpiece 6 to be measured. When the connection component 2 pulls the plugging member 31 to overcome the elastic force of the reset member 5 to move, the slide rail assembly 42 can guide the movement of the plugging member 31, so that the plugging member 31 is vertically abutted against the surface 61 to be sealed, and a uniform pressure is applied to the surface 61 to be sealed, so as to achieve uniform blocking of the through hole 62 on the surface 61 to be sealed. Specifically, the length direction of the slide rail is the second direction, which is parallel to the axial direction of the connection component 2.

[0078] In some embodiments of the present application, a slide seat 315 for connecting with the slide rail assembly 42 is provided at the bottom of the blocking member 31. Figure 4 and Figure 5 shown.

[0079] In some embodiments of the present application, the detection system also includes a workpiece clamp for fixing the workpiece 6 to be measured on the base 4, which can ensure that the position of the workpiece 6 to be measured is fixed on the base 4, and can prevent the connection component 2 from applying force to the sealing component 3, causing the workpiece 6 to be measured to move relative to the base 4, thereby causing sealing failure.

[0080] See also Figures 1 to 10 In some embodiments of the present application, the method of using the above detection system is as follows:

[0081] Step 1: The driving module and the workpiece 6 to be measured are arranged on the base 4. At this time, the blocking member 31 is away from the sealing surface 61 of the workpiece 6 to be measured under the action of the reset member 5; the driving module is arranged on the outside of the workpiece 6 to be measured, and the connecting member 2 is driven by the position adjustment member 1, so that the clamping part 21 points to the release position 3112 of the connecting part 311;

[0082] Step 2: The second sliding component 12 drives the connecting component 2 to extend in the second direction, so that the second shaft segment 212 passes through the through hole 62 and the release position 3112 in sequence and enters the concave cavity 3113 of the connecting portion 311; the first sliding component 11 drives the second sliding component 12 and the connecting component 2 to slide in the first direction, so that the clamping portion 21 moves from the release position 3112 to the locking position 3111;

[0083] Step 3: The second sliding component 12 drives the connecting component 2 to move toward the outside of the workpiece 6 to be measured, and the blocking component 3 is driven by the clamping portion 21 to move toward the surface to be sealed 61, and the sealing member 32 abuts against the surface to be sealed 61 to achieve the inner sealing of the workpiece 6 to be measured;

[0084] Step 4: introducing gas into the workpiece 6 to perform an airtightness test;

[0085] Step 5: After the detection is completed, the second sliding component 12 drives the connecting component 2 to move a certain distance toward the inner side of the workpiece 6 to be measured, and then the first sliding component 11 drives the clamping part 21 to move from the locking position 3111 to the release position 3112, and the limiting effect of the clamping part 21 on the connecting part 311 is released, and the blocking part 31 is moved away from the workpiece 6 to be measured under the elastic force of the reset part 5; after the second sliding component 12 drives the connecting component 2 to slide out of the workpiece 6 to be measured, the workpiece 6 to be measured on the base 4 can be loaded and unloaded.

[0086] The present application can be applied to the sealing of any device housing during the airtightness detection process, and has strong versatility. In addition, by detachably connecting the driving module and the blocking module, the blocking module and the driving module of the present application can be respectively arranged on the inner and outer sides of the workpiece 6 to be tested, and can be applied to the airtightness detection scene where the parts are assembled on the inner side of the through hole 62 to achieve sealing, and the internal space of the tested parts is narrow. This is conducive to ensuring the consistency of the airtightness detection results with the actual assembly state, making the detection results more meaningful for reference.

[0087] The above embodiments are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent substitution or change made by a person skilled in the art based on the present application is within the protection scope of the present application.
