The positioning plate is formed with a first positioning groove coaxially aligned with the threaded pins and a second positioning groove coaxially aligned with the anti-leakage punches. The top of the threaded pins passes through the first positioning groove and is exposed outwards, and the anti-leakage punches pass through the second positioning groove and are exposed outwards. The cover plate is detachably installed on top of the positioning plate and is formed with a guide groove for inserting the product.

[0007] Furthermore: the base plate is equipped with an upright positioning pin, and the positioning plate is formed with a first central positioning hole that is coaxially engaged with the positioning pin.

[0008] Furthermore: a foot block is installed at the bottom of the base plate, a positioning post is installed at the top of the foot block, and the positioning plate is formed with a second central positioning hole that is coaxial with the positioning post.

[0009] Furthermore: the cover plate is equipped with a top locking screw, the cover plate is formed with a top connecting hole that mates with the top locking screw, and the positioning plate is formed with a central connecting hole that is coaxially aligned with the top connecting hole.

[0010] Furthermore: the cover plate is formed with a top positioning hole that is coaxially aligned with the first central positioning hole.

[0011] Furthermore: the base plate is also formed with a bottom movable hole, the positioning plate is formed with a middle movable hole coaxially aligned with the bottom movable hole, and a top column is provided between the bottom movable hole and the middle movable hole, which can move axially to push the product out of the guide groove.

[0012] Furthermore, the base plate is equipped with a bottom drive mechanism that drives the top column to move up and down.

[0013] The beneficial effects of this utility model are as follows: The base plate, positioning plate, and cover plate are assembled, with the top of the perforation needle protruding through the first positioning groove and exposed to the top of the positioning plate, and the anti-leakage punch protruding through the second positioning groove and exposed to the top of the positioning plate. The cover plate is installed on top of the positioning plate, and then the product to be inspected can be placed into the guide groove. If there are defects in the appearance, it cannot be embedded into the guide groove, thus achieving shape inspection. If the appearance is qualified, the perforation needle and the anti-leakage punch cooperate with the product simultaneously, enabling punching inspection and perforation position inspection. Three functional inspections are simultaneously achieved within one fixture, integrating the original three inspection fixtures into one fixture, reducing labor costs and increasing inspection sales.

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-3As shown, the three-piece integrated inspection fixture includes a base plate 1, a positioning plate 2, and a cover plate 25. The base plate 1 has multiple thread pins 14 and anti-leakage punches 15 mounted on its top. The positioning plate 2 is formed with a first positioning groove 21 coaxially aligned with the thread pins 14 and a second positioning groove 22 coaxially aligned with the anti-leakage punches 15. The tops of the thread pins 14 are exposed outward through the first positioning groove 21, and the anti-leakage punches 15 are exposed outward through the second positioning groove 22. The cover plate 25 is detachably mounted on the top of the positioning plate 2 and is formed with a guide groove 26 for inserting the product.

[0027] Assemble the base plate 1, positioning plate 2, and cover plate 25. The top of the threaded pin 14 passes through the first positioning groove 21 and protrudes to the top of the positioning plate 2. The anti-leakage punch 15 passes through the second positioning groove 22 and protrudes to the top of the positioning plate 2. The cover plate 25 is installed on the top of the positioning plate 2. Then, the product to be inspected can be placed into the guide groove 26. If there are defects in the appearance, it cannot be embedded into the guide groove 26, thus achieving shape inspection. If the appearance is qualified, the threaded pin 14 and the anti-leakage punch 15 cooperate with the product at the same time to perform punching inspection and threaded hole position inspection on the product. Three functions of inspection are realized simultaneously in one fixture, integrating the original three inspection fixtures into one fixture, reducing labor costs and increasing inspection sales.

[0028] Furthermore, the base plate 1 is equipped with an upright positioning pin 11, and the positioning plate 2 is formed with a first central positioning hole 23 that coaxially engages with the positioning pin 11. The cover plate 25 is formed with a top positioning hole 30 that is coaxially aligned with the first central positioning hole 23. In this embodiment, when the base plate 1, the positioning plate 2, and the cover plate 25 are assembled, the positioning pin 11 sequentially engages with the first central positioning hole 23 of the positioning plate 2 and the top positioning hole 30 of the cover plate 25 to achieve precise assembly and ensure the accuracy of the test.

[0029] Furthermore, a foot pad 16 is installed at the bottom of the base plate 1, and a positioning post 17 is installed at the top of the foot pad 16. The positioning plate 2 is formed with a second central positioning hole 24 that mates coaxially with the positioning post 17. The foot pad 16 is connected to the base plate 1 through the positioning post 17, and the top of the positioning post 17 mates with the second central positioning hole 24 of the positioning plate 2, thereby further connecting the positioning plate 2 and the base plate 1 and ensuring the stability of the connection.

[0030] Furthermore, the cover plate 25 is equipped with a top locking screw 27, and the cover plate 25 is formed with a top connecting hole 28 that mates with the top locking screw 27. The positioning plate 2 is formed with a central connecting hole 29 that is coaxially aligned with the top connecting hole 28. When the cover plate 25 is installed, it is connected to the positioning plate 2 through the top locking screw 27 and the central connecting hole 29, thereby achieving a fixed connection between the cover plate 25 and the positioning plate 2, and it can also be disassembled and replaced.

[0031] Furthermore, the base plate 1 is also formed with a bottom movable hole 12, and the positioning plate 2 is formed with a central movable hole 18 coaxially aligned with the bottom movable hole 12. A top post 13 is provided between the bottom movable hole 12 and the central movable hole 18, which can move axially to push the product out of the guide groove 26. After the inspection is completed, since the product is embedded in the guide groove 26 of the cover plate 25, when it is necessary to eject the product, the top post 13 can be moved longitudinally to push the product out of the guide groove 26, thereby detaching it and allowing the next product to continue to be inspected.

[0032] Furthermore, the base plate 1 is equipped with a bottom drive mechanism that drives the top column 13 to move up and down. The bottom drive mechanism is a vertically moving lifting block. The vertical movement of the lifting block drives the top column 13 to move vertically, pushing the product out of the guide groove 26.

[0033] Preferably, the bottom drive mechanism further includes a longitudinally arranged lifting cylinder, the drive end of which is connected to the lifting block. In addition, a longitudinally arranged guide rail is provided at the bottom of the base plate 1, and the lifting block is slidably mounted on the guide rail. Two infrared sensors are arranged at intervals along the guide rail. The lifting block is equipped with a sensing block that cooperates with the infrared sensor. When the lifting block moves to cooperate with the infrared sensor at the bottom, the lifting cylinder stops working, and the top column 13 does not protrude at this time. When it is pushed out, the lifting cylinder moves, and when the lifting block moves to cooperate with the infrared sensor at the top, the lifting cylinder stops working. At this time, the top column 13 is pushed out completely. After a moment, the lifting cylinder drives the lifting block to move to cooperate with the infrared sensor at the bottom.

[0034] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
