Description

A glass sealing cover plate test fixture Technical Field

[0001] This invention relates to the field of component reliability testing equipment, and in particular to a glass fusion seal cover plate test fixture. Background Technology

[0002] To test the shear strength of the seal of a glass-sealed encapsulation cover (hereinafter referred to as the "encapsulation cover"), a torque is applied to the encapsulation cover to complete a torque test, which is a destructive test. The encapsulation cover consists of a cap at the top and a housing fixedly connected to the cap. During the torque test, the housing is supported and fixed using a fixture. After ensuring that the force and torque on the housing are primarily applied to the sealing area, a torque is applied to the cap on the fixture using a torque application mechanism. The cap and housing resist the torque until they break. The breakage threshold is the torque resistance value we need to measure, thus completing the encapsulation cover test.

[0003] When testing the housing using a fixture, the fixture must ensure that it does not apply torque to the side areas of the housing while supporting and fixing it. Therefore, it needs to be fixed by aligning the two sides of the housing. Since the width of the housing is greater than the width of the cover, the cover is not fixed by the fixture. The surface of the cover is smooth, making it difficult to apply torque directly to the cover through the torque application mechanism. As a result, the torque application between the cover and the housing is affected, making it impossible to conduct the experiment. Furthermore, the types and thicknesses of the packaging cover vary. Therefore, when the fixture clamps housings with packaging cover plates of different thicknesses, the height of some thinner packaging cover plates may be lower than the top surface of the fixture. This makes it impossible to use other structures to restrict the cover due to the influence of the fixture. The most important part of the torque test is to twist the body of the packaging cover plate on the fixture, that is, to break the connection between the cover and the housing, so as to detect the torque resistance value. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a glass sealing cover plate test fixture to solve the problem that it is difficult to apply torque to the cover.

[0005] To solve the above-mentioned technical problems, the present invention provides a glass sealing cover plate test fixture, specifically including a base, an adjusting positioner disposed on the base, and a wrench connector disposed on the adjusting positioner. The top surface of the base has a recessed mounting cavity along the Z-axis direction. The adjusting positioner includes a support unit located within the mounting cavity and connected to the base, and an adjusting unit disposed on the support unit for supporting and elevating the sealing cover plate. An operating space is formed through the top of the support unit along the X-axis direction. The adjusting unit is disposed within the operating space along the Y-axis direction. First clamping units are disposed on both sides of the operating space, moving along the X-axis direction to clamp or loosen the outer shell. The top surface height of the first clamping units is equal to... The adjustment unit supports the top surface of the support unit and is used to support the encapsulation cover. It can adjust the height of the encapsulation cover when it is placed on the adjustment unit, so that the top surface of the cover can always be higher than the top of the support unit, creating a height difference between it and the clamp, which facilitates the wrench connector to act on the cover. The wrench connector includes a second clamping unit located on the top surface of the adjusting positioner for clamping or releasing the cover along the X-axis direction, and a connecting unit installed on the top of the second clamping unit for connecting a torque wrench and locking the torque wrench in the X and Y axis directions. The second clamping unit clamps the part of the cover that is higher than the support unit, and the connecting unit enables the torque wrench to transmit torque to the cover clamped by the second clamping unit after connection, thus completing the torque test.

[0006] Furthermore, the support unit includes a base supported within the mounting cavity, the length of the adjustment unit in the X-axis direction is less than the length of the base in the X-axis direction and less than the length of the outer shell in the X-axis direction, and the operating space is formed on the top surface of the base; the first clamping unit includes two clamping blocks disposed on both sides of the operating space along the X-axis direction and abutting portions for respectively pressing the two clamping blocks against both sides of the base along the X-axis direction, the base and the two clamping blocks are slidably disposed on the base along the X-axis direction so that the base and the clamping blocks are always corresponding on the X-axis, and the distance between the two clamping blocks can be adjusted for clamping encapsulation covers of different widths.

[0007] Furthermore, the abutment includes a first bolt screwed onto the base along the X-axis at a position corresponding to the clamping block. The threaded section of the first bolt passes into the mounting cavity. By rotating the first bolt, the threaded section of the first bolt moves closer to or further away from the clamping block, thereby adjusting the distance between the two clamping blocks to clamp or loosen encapsulation covers of different widths.

[0008] Furthermore, the adjustment unit includes a support portion that is slidably disposed in the operating space along the X-axis and capable of telescoping along the Z-axis, and a rotation adjustment portion that is rotatably disposed in the operating space along the Y-axis. The top surface of the support portion has a support surface for supporting the encapsulation cover plate, so that the encapsulation cover plate can be placed on the support surface and kept horizontal. The rotation adjustment portion is capable of rotating along its own axis, and one end of the rotation adjustment portion is screwed to the base, while the other end moves through the base and the base in sequence. The rotation adjustment portion is connected to the support portion so that the support portion can be telescoped by rotation, thereby realizing the adjustment of the support portion in the Z-axis direction.

[0009] Furthermore, the support includes two first sliders spaced apart and slidably disposed in the operating space along the X-axis, a telescopic frame with a cross-shaped shear structure hinged to the two first sliders on both sides of the bottom, and a pad for supporting the encapsulation cover. The top two sides of the telescopic frame are slidably hinged to the two sides of the telescopic pad along the X-axis. The rotation adjustment part is connected to the two first sliders respectively, so that the two first sliders can be moved closer to each other by rotation, so as to increase the height of the pad and achieve the purpose of raising the encapsulation cover.

[0010] Furthermore, the rotation adjustment unit includes an adjustment cylinder rotatably connected to the inner wall of the operating space along the Y-axis, a pull rope wound around the adjustment cylinder, and a locking pin adapted to be inserted into the adjustment cylinder along the Y-axis. The two ends of the pull rope are respectively connected to two first sliders. When the locking pin is rotated, the adjustment cylinder adapted to the locking pin rotates accordingly, and the two ends of the pull rope pull the two first sliders in opposite directions, thereby increasing the height of the pad. At the same time, one end of the locking pin moves through one end of the base and the base, and the other end is screwed to the other end of the base. Thus, when the locking pin is rotated, the base can also lock the locking pin after the locking pin is released, preventing the locking pin from continuing to rotate and changing the already adjusted height of the pad. At the same time, the whole operation process is simple and easy to use, and the locking pin screwed to the base keeps the whole structure stable.

[0011] Furthermore, the second clamping unit includes a first clamp and a second clamp spaced apart along the X-axis for clamping the cap. The first clamp and the second clamp are provided with a clamping part for adjusting the distance between the first clamp and the second clamp along the X-axis. The bottom surfaces of the first clamp and the second clamp are flush with each other and supported on the top surface of the support unit so as to clamp the cap that is higher than the top of the support unit in order to restrict the cap.

[0012] Furthermore, the tightening part includes at least two second bolts, each of which is screwed onto the first clamp and the second clamp at equal intervals along the Y-axis direction, and each of the second bolts is distributed perpendicular to the first clamp and the second clamp, so that the first clamp and the second clamp can clamp caps of different widths.

[0013] Furthermore, each of the first and second clamps has a corresponding through slot along the X-axis. The bottom sides of the connecting unit are respectively adapted to be inserted into the two through slots along the X-axis. An action end for connecting and locking the torque wrench is formed on the top of the connecting unit. While the first and second clamps clamp the cover, the first and second clamps also lock the position of the connecting unit.

[0014] Furthermore, the connecting unit includes a connecting block arranged along the X-axis and adapted to be inserted into two slots at both ends, and a connecting rod adapted to be inserted into the connecting block along the Z-axis. The working end is recessed in the top of the connecting rod along the Z-axis, so that the torque wrench can apply torque through the working end to drive the entire wrench connector to rotate, thereby driving the cover to rotate to apply torque, so as to complete the torque test of the sealing cover.

[0015] The glass sealing cover plate test fixture of the present invention has at least the following beneficial effects:

[0016] By setting the first clamping unit of the adjusting positioner to restrict the outer shell of the cover plate, the height of the entire encapsulation cover plate is adjusted by the adjusting unit so that the top surface of the cover plate is higher than the top surface of the support unit, forming a height difference. The second clamping unit of the wrench connector is adjusted to clamp the cover plate portion that is higher than the support unit, and in conjunction with the connecting unit, the torque wrench can apply torque to the cover plate clamped by the second clamping unit until the cover plate and the outer shell are twisted. At the same time, the torque of the encapsulation cover plate is easily tested by the torque wrench through an external detection device. Attached Figure Description

[0031] The invention will now be further described with reference to the accompanying drawings.

[0032] Figure 1 shows the glass sealing cover plate (hereinafter referred to as "encapsulation cover plate 1") targeted by the present invention. The encapsulation cover plate 1 consists of a rectangular sheet-like outer shell 11, a rectangular sheet-like cover 12 fixedly connected to the top of the outer shell 11, and a plurality of pins 13 fixed at equal intervals on both sides of the outer shell 11. Each pin 13 is arranged along the Z-axis and located on the two long sides of the outer shell 11. In the present invention, the width direction of the encapsulation cover plate 1 corresponds to the X-axis direction, the length direction of the encapsulation cover plate 1 corresponds to the Y-axis direction, and the thickness direction of the encapsulation cover plate 1 corresponds to the Z-axis direction, in order to facilitate understanding of the structure and orientation of the present invention.

[0033] Referring to Figures 2 to 8, a glass sealing cover plate test fixture of the present invention includes a base 2, an adjusting positioner 3 disposed on the base 2 for limiting the outer shell 11, and a wrench connector 4 for limiting the cover 12. The base 2 facilitates the use of external fixing devices such as bench vises to fix the entire fixture; the adjusting positioner 3 supports the sealing cover 1 and clamps the outer shell 11, and at the same time, the adjusting positioner 3 can adjust the height of the sealing cover 1 so that the height of the cover 12 is higher than the entire adjusting positioner 3, so as to facilitate the operation of the cover 12; and the wrench connector 4... This is used to clamp the portion of the cover 12 that is higher than the adjusting positioner 3. After clamping the cover 12, the torque wrench is connected to the wrench connector 4 and rotated. The torque wrench transmits torque to the wrench connector 4 to drive the entire wrench connector 4 to rotate. The cover 12 clamped by the wrench connector 4 bears the transmitted torque until the cover 12 and the outer shell 11 are twisted and broken. By measuring the breaking threshold, the torque resistance value of the encapsulation cover 1 is obtained. In this way, the torque can be easily applied to the cover 12 without destroying it, and the torque test is completed.

[0034] As shown in Figures 2 to 4, in the scope of this invention, the base 2 has a cuboid structure. The length of the base 2 is arranged along the Y-axis, the width along the X-axis, and the thickness along the Z-axis. The base 2 has a top surface and a bottom surface along the Z-axis. A mounting cavity 21 is recessed into the top surface of the base 2 along the Z-axis. The mounting cavity 21 is cuboid in shape, but can also have other structures. The bottom surface of the mounting cavity 21 can be sealed by the base 2, or it can extend through the base 2 along the Z-axis. When the mounting cavity 21 extends through the base 2, protruding platforms can be formed on any two opposite sides of the mounting cavity 21. The two protruding platforms are spaced apart and their top surfaces are flush, forming a platform to support other structures. This facilitates the removal of objects from the mounting cavity 21 when the structure inside the mounting cavity needs to be disassembled, allowing for easier removal of objects from between the two protruding platforms.

[0035] As shown in Figures 4 to 8, the adjusting positioner 3 includes a support unit 31 located in the mounting cavity 21 and connected to the base 2, an adjusting unit 32 disposed on the support unit 31 for supporting and elevating the encapsulation cover plate 1, and a first clamping unit 33 located in the mounting cavity 21 for fixing the encapsulation cover plate 1 on the adjusting unit 32. The support unit 31 is used to support and stabilize the adjusting unit 32. The adjusting unit 32 is used to horizontally place the encapsulation cover plate 1 and adjust the height of the encapsulation cover plate 1 placed on the adjusting unit 32 so that the top surface height of the cover 12 is higher than the top surface height of the support unit 31. The first clamping unit 33 positions the encapsulation cover plate 1 on the adjusting unit 32 after the adjusting unit 32 has adjusted the height of the encapsulation cover plate 1 to prevent the encapsulation cover plate 1 from shifting and affecting the application of torque.

[0036] The support unit 31 can be fixedly mounted on the base 2 or detachably connected to the base 2. In this embodiment, the support unit 31 is detachably mounted in the mounting cavity 21. The support unit 31 includes a base 311 supported in the mounting cavity 21. An operating space 312 is formed downward along the X-axis at the center of the top surface of the base 311. An adjustment unit 32 is disposed in the operating space 312 along the Y-axis so that the length of the adjustment unit 32 corresponds to the Y-axis. The length of the operating space 312 in the Y-axis direction is its length, and the length of the operating space 312 in the X-axis direction is its width. The length of the operating space 312 is greater than the length of the encapsulation cover 1, and the width of the base 311 is equal to the width of the operating space 312 and less than or equal to the width of the outer shell 11, so that the encapsulation cover 1 can be placed in the operating space 312 and the two long sides of the encapsulation cover 1 are aligned with or extend out of the operating space 312. Preferably, the width of the operating space 312 is less than the width of the housing 11, so that the pins 13 on both sides of the housing 11 can be located outside the operating space 312, avoiding damage to the pins 13. Bases 313 are formed on the base 311 on both sides of the operating space 312, with the top surfaces of the two bases 313 being of the same height and flush, so that the first clamping unit 33 can confine the housing cover 1 within it, and also facilitates the adjustment unit 32 to create a height difference between the housing cover 1 and the clamping unit 32. Both bases 313 have first through holes 314 formed along the X-axis. On the two long sides of the mounting cavity 21, corresponding to the positions of the first through holes 314, second through holes 22 with the same diameter as the first through holes 314 are formed. The second through holes 22 penetrate the inside and outside of the base 2. Two first screws 23 are provided on the base 2 along the X-axis. The two first screws 23 pass sequentially through the two second through holes 22 on one side of the base 2, then through the corresponding first through holes 314, until they exit through the two second through holes 22 on the other side of the base 2. The two first screws 23 are then fixed to the base 2 by first nuts. The base 311 can then slide freely relative to the base 2. This allows for the installation of bases 311 of different sizes as needed.

[0037] The adjustment unit 32 includes a support part 321 that is slidably disposed in the operating space 312 along the X-axis and can extend and retract along the Z-axis, and a rotation adjustment part 322 that is disposed in the operating space 312 along the Y-axis and can rotate along its own axis. The top surface of the support part 321 has a support surface for supporting the encapsulation cover plate 1, so that the encapsulation cover plate 1 can be placed, and the support part 321 can support the encapsulation cover plate 1. One end of the rotation adjustment part 322 is screwed to the base 311, and the other end moves through the base 311 and the base 2 in sequence. The rotation adjustment part 322 is connected to the support part 321 so that the support part 321 can extend and retract by rotating, thereby adjusting the extension and retraction degree of the support part 321 in the Z-axis direction, so as to achieve the purpose of adjusting the height, so that the top surface of the cover 12 can always be higher than the top surface of the base 313, so that the wrench connector 4 can operate the cover 12. It should be noted that the adjustment unit 32 can be replaced with a shim. When the adjustment unit 32 is a shim, the shim of different thickness can be replaced for different encapsulation cover plates 1.

[0038] The support portion 321 includes two first sliders 3211 spaced apart along the X-axis and slidably disposed within the operating space 312, a scissor-shaped telescopic frame 3212 hinged to the two first sliders 3211 on its bottom sides respectively, and a pad 3213 for supporting the encapsulation cover plate 1. Both first sliders 3211 can slide along the X-axis to move towards or away from each other. The top two sides of the telescopic frame 3212 are slidably hinged to the sides of the telescopic pad 3213 along the X-axis respectively. When the two first sliders 3211 move towards or away from each other, they drive the bottom two sides of the telescopic frame 3212 to move towards or away from each other, thereby causing the scissor-shaped telescopic frame 3212 to extend or shorten. The top two sides of the telescopic frame 3212 move synchronously with the bottom two sides towards or away from each other, thereby driving the pad 3213 to move in the Z-axis direction, achieving the purpose of adjusting the height of the pad 3213. The rotation adjustment unit 322 is connected to the two first sliders 3211 respectively. The rotation adjustment unit 322 drives the two first sliders 3211 to move towards each other by rotation, thereby adjusting the height of the pad 3213. This adjustment method is not only simple to operate, but also convenient and quick to use. It can support different encapsulation covers 1 without taking too much time, and when the pad 3213 supports different encapsulation covers 1, the height of the cover 12 is always higher than the top surface of the base 313. It should be noted that the minimum length of the entire support part 321 in the Z-axis direction, that is, the minimum thickness of the support part 321, is less than the depth of the operating space 312, so that the support part 321 can allow a part of the outer shell 11 to be located within the operating space 312, which facilitates the clamping unit 33 to clamp the outer shell 11.

[0039] Both first sliders 3211 are identical in shape and size, and are elongated structures. At least one inverted "T"-shaped slide rail 3214 is provided at the bottom of each first slider 3211 along the X-axis. An inverted "T"-shaped first groove 315 is formed on the bottom surface of the operating space 312, corresponding to the position of the slide rail 3214, extending along the X-axis. This groove restricts the first sliders 3211's freedom of movement in the Y and Z axes when they are installed or removed, allowing them to move only along the X-axis. At least two telescopic frames 3212 are provided, each located between the first slider 3211 and the pad 3213, and symmetrically distributed about the center line of the pad 3213 parallel to the X-axis, to ensure the pad 3213 remains stable as much as possible. Each telescopic frame 3212 is formed by two centrally rotating and intersecting connecting rods. The telescopic frame 3212 is arranged along the X-axis direction, and of its four ends, the two top ends are connected to the pad 3213, and the two bottom ends are respectively hinged to the two first sliders 3211 via hinge seats, so that the bottom and top ends of the two connecting rods can move closer or further apart after the two first sliders 3211 move towards or away from each other, thereby allowing the telescopic frame 3212 to extend or shorten in the Z-axis direction. The pad 3213 has a cuboid sheet structure, and the length, width, and height of the pad 3213 correspond to the length, width, and height of the encapsulation cover 1. The width of the pad 3213 is less than the width of the outer shell 11, and the length of the pad 3213 is less than the length of the operating space 312. The maximum width of the telescopic frame 3212 in the X-axis direction is less than the width of the pad 3213, so that the two long sides of the outer shell 11 can be clamped by the first clamping unit 33. A sliding groove is provided along the X-axis on the bottom surface of the pad 3213 at the two ends of the top of each telescopic frame 3212. A sliding block is hinged to both ends of the top of each telescopic frame 3212. The sliding block is slidably disposed in the sliding groove so that the telescopic frame 3212 can extend and retract relative to the pad 3213 and drive the pad 3213 to adjust its height.

[0040] The rotation adjustment unit 322 includes an adjustment cylinder 3221 rotatably connected to the inner wall of the operating space 312 along the Y-axis, a pull rope 3222 wound around the adjustment cylinder 3221, and a locking pin 3223 adapted to be inserted into the adjustment cylinder 3221 along the Y-axis. The adjustment cylinder 3221 can rotate along its own axis, and the pull rope 3222 is wound around the adjustment cylinder 3221. When the adjustment cylinder 3221 is rotated, the pull rope 3222 is wound around the adjustment cylinder 3221 or unwound from the adjustment cylinder 3221, thereby causing the two ends of the pull rope 3222 to lengthen or shorten. The two ends of the pull rope 3222 are respectively connected to two first sliders 3211. When the adjustment cylinder 3221 is rotated and the two pull ropes 3222 are shortened, the two ends of the pull rope 3222 pull the two first sliders 3211 towards each other, so that the two first sliders 3211 slide towards each other and lengthen, thereby achieving the purpose of adjusting the height of the telescopic frame 3212. One end of the locking pin 3223 moves through one end of the base 311 and the corresponding side of the base 2, while the other end of the locking pin 3223 is screwed to the other end of the base 311. Thus, when the locking pin 3223 is rotated, while the adjusting cylinder 3221 rotates, the locking pin 3223 remains screwed to the base 311. This restricts the locking pin 3223 to rotate only when an external force is used to rotate it. Otherwise, the locking pin 3223, which is threaded to the base 311, cannot rotate due to the restriction of the thread on the base 311. This automatically locks the locking pin 3223 after the height is adjusted, preventing the locking pin 3223 from continuing to rotate and causing the telescopic frame 3212 to become unstable and retract, which would result in the top surface height of the cover 12 being lower than the top surface height of the base 313.

[0041] In this embodiment, two coaxially distributed support blocks are spaced apart at the midpoint of the operating space 312 along the Y-axis. Each support block has a third through hole 3225 with a diameter greater than the diameter of the locking pin 3223, extending along the Y-axis. The third through hole 3225 is coaxially distributed with the support block. A second annular groove is coaxially formed around the third through hole 3225 on one side of the two supporting blocks facing each other. An adjusting cylinder 3221 is located between the two support blocks and coaxially distributed with them, with a gap between the adjusting cylinder 3221 and the bottom surface of the operating space 312 to avoid affecting its rotation. At each end of the adjusting cylinder 3221, corresponding to the position of the second groove, a second annular slider is formed that slides smoothly with the second groove, allowing the two ends of the adjusting cylinder 3221 to be rotatably mounted on the two support blocks. A prismatic through-hole 3224, coaxially arranged with the adjusting cylinder 3221 along the Y-axis, is provided on the adjusting cylinder 3221. The diameter of the prismatic hole is smaller than the inner diameter of the second slider, thus not affecting the rotational fit between the adjusting cylinder 3221 and the support block. Alternatively, the support block can be omitted, and the second sliding groove can be provided on both sides of the operating space 312, so that both ends of the adjusting cylinder 3221 extend to the two second sliding grooves and the second slider is movably positioned within the second sliding grooves. The prismatic hole has a prism-shaped structure and can be a triangular prism, a quadrangular prism, etc.

[0042] At least two pull ropes 3222 are symmetrically arranged on the adjusting cylinder 3221. The middle of each pull rope 3222 is fixed to the adjusting cylinder 3221. The two ends of each pull rope 3222 are wound around the adjusting cylinder 3221 in opposite directions and extend towards the two sliders respectively, connecting to the two sliders. Preferably, a spring (not shown in the figure) can be arranged between the two sliders along the X-axis. The spring is always in a compressed state. When the adjusting cylinder 3221 is rotated, the two ends of the two pull ropes 3222 on the adjusting cylinder 3221 move closer or further away from the adjusting cylinder 3221. When the two ends of the pull ropes 3222 are close together, they will pull the two first sliders 3211 to slide towards each other, so that the telescopic frame 3212 is extended. When the two ends of the pull ropes 3222 are far apart, they will no longer pull the two first sliders 3211, and the spring will extend at this time, so that the two sliders slide in opposite directions until the pull ropes 3222 are taut.

[0043] The locking pin 3223 is a long rod structure, and the length of the locking pin 3223 is greater than the length of the base 2. The locking pin 3223 includes a prism segment 32231 that is adapted to the prism through hole 3224 and a threaded segment 32232 that is screwed to the base 311. The prism segment 32231 and the threaded segment 32232 are arranged along the length direction and connected sequentially. The shape of the prism segment 32231 is consistent with the shape of the prismatic through hole 3224. The prism segment 32231 is movably inserted into the prismatic through hole 3224, and when the prism segment 32231 is inserted into the prismatic through hole 3224, there is a gap of less than 1mm between each side wall of the prism segment 32231 and the inner wall of the prismatic through hole 3224, so that the prism segment 32231 can be inserted into the prismatic through hole 3224 along the Y-axis direction. When the entire locking pin 3223 is rotated, the prism segment 32231 that matches the prismatic through hole 3224 can drive the adjusting cylinder 3221 to rotate, thereby causing the two ends of the pull rope 3222 to contract or extend relative to the adjusting cylinder 3221, realizing the height adjustment of the support part 321. The diameter of the threaded segment 32232 is less than the diameter of the prismatic through hole 3224, so that the threaded segment 32232 can freely pass through the prismatic through hole 3224. On one of the bases 313, a first threaded hole 217 is formed along the Y-axis, directly opposite the prismatic through hole 3224, to engage with the threaded segment 32232. On the other base 313, a fourth through hole 316 is formed along the Y-axis, directly opposite the prismatic through hole 3224. The diameter of the fourth through hole 316 is greater than the maximum radial length of the prismatic segment 32231. On the first upper part of the base 2 facing the fourth through hole 316, a fifth through hole 24 is formed along the Y-axis, directly opposite the fourth through hole 316. The diameter of the fifth through hole 24 is equal to the diameter of the fourth through hole 316. The end of the prismatic segment 32231 away from the threaded segment 32232 passes through the fourth through hole 316 and the fifth through hole 24 in sequence until it exits the fifth through hole 24. At the end of the prism segment 32231 that passes through the fifth through hole 24, a head with a diameter or size much larger than the fifth through hole 24 is fixedly connected to facilitate the rotation of the locking pin 3223. The structure defined in this embodiment makes the entire locking pin 3223 easy to disassemble and replace, so that it can be replaced in time when the locking pin 3223 is damaged and affects the use of the entire fixture. When replacing, simply rotate the head in the opposite direction to disengage the threaded segment 32232 from the first threaded hole 217 and then pull out the locking pin 3223 along the Y-axis to complete the disassembly.During installation, one end of the threaded section 32232 is passed sequentially through the fifth through hole 24, the fourth through hole 316, and the prismatic through hole 3224, and finally screwed into the first threaded hole 217. Through the cooperation between the first threaded hole 217 and the threaded section 32232, the connection stability between the locking pin 3223 and the base 311 is ensured, while limiting the rotation of the locking pin 3223 and the adjusting cylinder 3221. When the locking pin 3223 is rotated by external force, the locking pin 3223 and the adjusting cylinder 3221 will rotate. Otherwise, the adjusting cylinder 3221 will not rotate and will affect the cooperation between the pull rope 3222 and the first slider 3211. The entire process only requires one action of rotating the locking pin 3223 to complete multiple functions such as height adjustment of the support 321 and locking of the adjusting cylinder 3221, making it ingenious and easy to use.

[0044] In use, the sealing cover 1 is placed on the pad 3213. At this time, the height of the support part 321 needs to be adjusted based on the height difference between the top surface of the cover 12 and the top surface of the base 313. When the top surface of the cover 12 is lower than the top surface of the base 313, the head is rotated in the forward direction, and the threaded section 32232 rotates into the first threaded hole 217. The adjusting cylinder 3221, which is adapted to be inserted into the prism section 32231, rotates accordingly. The pull rope 3222 continues to be wound around the adjusting cylinder 3221 so that the two ends of the pull rope 3222 shorten towards each other, thereby pulling the two first sliders 3211 to slide towards each other, so that the telescopic frame 3212 extends along the Z-axis until the top surface of the cover 12 is higher than the top surface of the base 313, and at least a part of the outer shell 11 is located within the operating space 312, thus completing the height adjustment. When the bottom surface of the outer shell 11 is higher than the top surface of the base 313, the head is rotated in the opposite direction, and the threaded section 32232 moves outward toward the first threaded hole 217. The adjusting cylinder 3221 also rotates in the opposite direction, causing the two ends of the pull rope 3222 to loosen from the adjusting cylinder 3221 and extend in the opposite direction. The two first sliders 3211, which gradually lose the restraint of the pull rope 3222, slide in the opposite direction under the action of the spring until the bottom surface of the outer shell 11 is lower than the top surface of the base 313, and then the head stops rotating. In this way, the height adjustment of the sealing cover 1 can be completed, so that there is always a height difference between the top surface of the cover 12 and the top surface of the base 313, so that the wrench connector 4 can hold the cover 12.

[0045] The top surface height of the first clamping unit 33 is equal to the top surface height of the support unit 31, so that it will not affect the use of the wrench connector 4. The first clamping unit 33 includes two clamping blocks 331 disposed on both sides of the operating space 312 along the X-axis direction, and abutment portions 332 for respectively pressing the two clamping blocks 331 against both sides of the base 311 along the X-axis direction. The two clamping blocks 331, like the base 311, are slidably disposed on the base 2 along the X-axis direction. The two clamping blocks 331 move towards each other in cooperation with the abutment portions 332 to clamp and fix the two long sides of the outer shell 11 in the operating space 312, thereby facilitating the operation of the cover 12.

[0046] Between the two long sides of the base 311 and the two long sides of the mounting cavity 21, there are two adjustment spaces for the two clamping blocks 331 to pass through. The two clamping blocks 331 are respectively located in the two adjustment spaces, and the length direction of the two clamping blocks 331 is arranged along the Y-axis. Preferably, the two clamping blocks 331 are the same in shape and size, and the length of the clamping block 331 is equal to the length of the base 311, and the height of the clamping block 331 is equal to the height (thickness) of the base 311, so that the clamping blocks 331 and the base 311 can be installed together in the mounting cavity 21 and maintain the same height. A sixth through hole 333 is formed along the X-axis on both clamping blocks 331 at a position directly opposite the first through hole 314. During installation, the first screw 23 passes through the second through hole 22, then through the sixth through hole 333 and the first through hole 314, and finally exits through another second through hole 22, thereby achieving a sliding fit between the base 311 and the two clamping blocks 331 on the X-axis. It should be noted that the pin 13 of the encapsulation cover plate 1 is located between the outer shell 11 and the clamping block 331. The clamping of the outer shell 11 by the clamping block 331 mainly acts on the pin 13, clamping the outer shell 11 simultaneously by clamping the pin 13.

[0047] The supporting part 332 includes a first bolt screwed onto the base 2 along the X-axis at a position corresponding to the clamping block 331. The shank of the first bolt is inserted into the mounting cavity 21 to move the clamping block 331 toward the long side of the outer shell 11 until it abuts against the outer shell 11, thus restricting the degree of freedom of the outer shell 11 in the X-axis direction. In this embodiment, a second threaded hole 25 is provided along the X-axis on both sides of the long side of the base 2, i.e., on both sides of the base 2 where the second through hole 22 is provided. The first bolt is screwed onto the second threaded hole 25 and extends along the shank into the adjustment space. After the height of the supporting part 321 is adjusted appropriately, the first bolts on both sides of the base 311 are rotated until the two clamping blocks 331 are pressed against the outer shell 11, thereby achieving the positioning of the outer shell 11.

[0048] As shown in Figures 2 to 4, the wrench connector 4 includes a second clamping unit 41 located on the top surface of the adjusting positioner 3 for clamping or loosening the cover 12 along the X-axis direction, and a connecting unit 42 mounted on top of the second clamping unit 41 for connecting a torque wrench and locking the torque wrench in the X and Y axis directions. When a torque test is required, after the second clamping unit 41 clamps the cover 12, the torque wrench is connected to the connecting unit 42, causing the torque wrench to rotate and transmit torque to the second clamping unit 41 and the cover 12 on the second clamping unit 41 through the connecting unit 42, until the cover 1 is broken, thus obtaining the test result. The cooperation between the second clamping unit 41 and the connecting unit 42 allows the torque wrench to accurately transmit torque to the cover 12 without direct contact, thereby testing the breakage threshold between the cover 12 and the outer shell 11 and achieving the test objective.

[0049] The second clamping unit 41 includes a first clamp 411 and a second clamp 412 spaced apart along the X-axis for clamping the cover 12, and a tightening part 413 disposed along the X-axis on the first clamp 411 and the second clamp 412 for adjusting the distance between the first clamp 411 and the second clamp 412. The first clamp 411 and the second clamp 412 are located on both sides of the cover 12. The tightening part 413 causes the first clamp 411 and the second clamp 412 to move towards each other until the cover 12 is clamped. The connecting unit 42 is connected to the first clamp 411 and the second clamp 412. After the first clamp 411 and the second clamp 412 clamp the cover 12, the torque wrench can transmit torque to the cover 12 through the connecting unit 42.

[0050] The first chuck 411 and the second chuck 412 are identical in size and shape. The length of the first chuck 411 and the second chuck 412 corresponds to the Y-axis direction, the width of the first chuck 411 and the second chuck 412 corresponds to the X-axis direction, and the height of the first chuck 411 and the second chuck 412 corresponds to the Z-axis direction. Both the first clamp 411 and the second clamp 412 are rectangular flat structures, with one side of the first clamp 411 and the second clamp 412 facing each other being a vertical plane for clamping the cap 12. The bottom surfaces of the first clamp 411 and the second clamp 412 are flush and can be supported on the top surface of the clamping block 331 and the base 313. This allows the first clamp 411 and the second clamp 412 to be supported on the top surface of the base 313 before clamping the cap 12 via the tightening part 413, eliminating the need for manual handling and lifting of the first clamp 411 and the second clamp 412, thus reducing the labor intensity of the operator. Correspondingly, the length of the first clamp 411 and the second clamp 412 is greater than the length of the operating space 312, so that the first clamp 411 and the second clamp 412 can be supported on the base 313.

[0051] Preferably, both the first chuck 411 and the second chuck 412 have through slots 414 along the X-axis that are adapted to the bottom sides of the connecting unit 42. The slots 414 on the first chuck 411 and the second chuck 412 are directly opposite each other in the X-axis direction. The bottom sides of the connecting unit 42 are respectively fitted into the two slots 414 along the X-axis direction. Before the first chuck 411 and the second chuck 412 adjust the distance through the tightening part 413, the bottom sides of the connecting unit 42 are respectively fitted into the two slots 414. When the cover 12 is clamped by the first chuck 411 and the second chuck 412, the slots 414 simultaneously restrict the degree of freedom of the connecting unit 42 in the X-axis and Y-axis, so that the connecting unit 42 can drive the first chuck 411 and the second chuck 412 to rotate when the torque wrench is rotated, thereby transmitting torque to the cover 12. A flange is formed along the X-axis on either the facing or back-facing side of the first chuck 411 and the second chuck 412. The top surface of the flange is flush with the bottom surface of the locking slot 414 to support the connecting unit 42 and improve the durability of the first chuck 411 and the second chuck 412.

[0052] The tightening part 413 includes at least two second bolts, and third threaded holes 415 are respectively opened on the first chuck 411 and the second chuck 412 in the X-axis direction corresponding to the number of second bolts. The third threaded holes 415 on the first chuck 411 and the second chuck 412 are evenly distributed and sequentially distributed in the Y-axis direction. The third threaded holes 415 on the first chuck 411 and the second chuck 412 are arranged facing each other in the X-axis direction so that each second bolt can pass through the third threaded holes 415 on the first chuck 411 and the second chuck 412 in the X-axis direction, so that each second bolt is distributed perpendicular to the first chuck 411 and the second chuck 412. After rotating the second bolt, the distance between the first chuck 411 and the second chuck 412 can be adjusted, thereby clamping the part of the cover 12 that is higher than the base 313 until the cover 12 is clamped. Finally, a second nut is screwed on the end of each second bolt that protrudes from the two chucks. The third threaded hole 415 can be replaced with the eighth through hole, and the cap 12 can be clamped by the cooperation between the second bolt and the second nut.

[0053] In use, after the outer shell 11 is clamped by the two clamping blocks 331, the first clamp 411 and the second clamp 412 are supported on the base 313, so that the cover 12 is located between the first clamp 411 and the second clamp 412. Then, the second bolt is rotated so that the first clamp 411 moves towards each other to gradually approach the cover 12. The first clamp 411 and the second clamp 412 clamp the cover 12, thus completing the clamping of the cover 12.

[0054] The connecting unit 42 includes a connecting block 421 arranged along the X-axis and adapted at both ends to be inserted into two slots 414, and a connecting rod 422 adapted at the bottom along the Z-axis to be inserted into the connecting block 421. The length of the connecting block 421 is greater than the width of the cover 12, and the length of the connecting block 421 is arranged in the X-axis direction. After the two ends of the connecting block 421 are inserted into the two slots 414, the connecting block 421 is perpendicular to the first clamp 411 and the second clamp 412. After the first clamp 411 and the second clamp 412 clamp the cover 12, the position of the connecting block 421 relative to the first clamp 411 and the second clamp 412 is also relatively restricted. The connecting block 421 has a cuboid structure. The length and width of the locking slot 414 correspond to and fit the width and height of the connecting block 421, respectively. The locking slot 414 has a rectangular hole structure, and the length of the locking slot 414 is greater than the width of the connecting block 421. The difference between the length of the locking slot 414 and the width of the connecting block 421 is within 1 mm to ensure proper fitting during insertion. The width of the locking slot 414 is greater than the height of the connecting block 421, and the difference between the width of the locking slot 414 and the height of the connecting block 421 is within 1 mm, so that the connecting block 421 can only move along the X-axis relative to the locking slot 414. A square hole 4211 is provided in the middle of the connecting block 421 along the Z-axis. A square head 4221 is provided at the bottom of the connecting rod 422 corresponding to the square hole 4211. The square head 4221 is a quadrangular prism structure. The square head 4221 is fitted into the square hole 4211 along the Z-axis so that when the connecting rod 422 rotates, it can drive the connecting block 421 to rotate, thereby driving the first chuck 411 and the second chuck 412 to rotate. An action end 4222 for connecting and locking the torque wrench is formed at the top of the connecting rod 422. The action end 4222 is designed according to the sleeve structure of the torque wrench. When the sleeve has a hexagonal groove at the bottom, the action end 4222 is hexagonal. When the sleeve has a hexagonal or square head, the top surface of the action end 4222 is recessed to form a hexagonal or square groove. When the action end 4222 is engaged with the sleeve, there is a gap of less than 1 mm between the action end 4222 and the side wall of the sleeve in contact.

[0055] In use, the connecting block 421 is inserted sequentially into the two slots 414 along the X-axis, and the square head 4221 of the connecting rod 422 is inserted into the square hole 4211. The sleeve of the torque wrench is connected to the working end 4222. Then, turning the connecting rod 422 means driving the connecting block 421 to rotate, and transmitting torque to the cover 12 through the first clamp 411 and the second clamp 412 until the experimental result is obtained, thus completing the torque test of the sealing cover 1.
