[0054] A first laser rangefinder 41 is installed above the fixed measuring rod 23 on the side near the movable measuring rod 24, and a second laser rangefinder module 42 is installed at the top of the auxiliary measuring plate 25 near the fixed measuring rod 23.

[0055] The auxiliary rod assembly includes an auxiliary rod 8. An auxiliary slider is installed above and below the side of the auxiliary rod 8 adjacent to the limiting structure 7. A fifth auxiliary groove is provided through the sliding block 5 at the location of the auxiliary rod 8, and the fifth auxiliary groove is parallel to the limiting rod 752. A sixth auxiliary groove is provided in the sliding block 5 at the location of the auxiliary slider, and the side of the auxiliary slider away from the limiting structure 7 is connected to the sixth auxiliary groove through multiple second springs 81.

[0056] The initial state of the auxiliary rod assembly is that the auxiliary rod assembly is located in the corresponding pressing slider 5. When the limiting rod 752 presses against the auxiliary rod 8, the other side of the auxiliary rod 8 is inserted into the locking cavity of the auxiliary measuring plate 25. At this time, the second spring 81 is in a deformed state. When the limiting rod 752 no longer presses against the auxiliary rod 8, the auxiliary rod 8 is reset under the action of the second spring 81, and the auxiliary rod assembly is located in the pressing slider 5.

[0057] Multiple first limiting components 91 and second limiting components 92 are symmetrically arranged on both sides below the auxiliary measuring component 26 inside the auxiliary measuring plate 25. A movable pressing rod 93 driven by a second servo motor is provided on one side inside the auxiliary measuring plate 25. The second servo motor is not shown in the figure.

[0058] The first limiting component 91 is located on the side away from the limiting structure 7, and the second limiting component 92 is located on the side close to the limiting structure 7. At the same time, the fixing axis of the first limiting component 91 is located on the side adjacent to the fixed measuring rod 23, and the fixing axis of the second limiting component 92 is located on the side away from the fixed measuring rod 23.

[0059] Meanwhile, both the first limiting component 91 and the second limiting component 92 include a connecting slide rod 95 and multiple movable rocker plates 901. An movable cavity is provided in the auxiliary measuring plate 25 at the movable rocker plate 901. A fixed shaft is inserted through one side of the movable rocker plate 901. Both ends of the fixed shaft are connected to the inner wall of the adjacent movable cavity. A fifth spring 903 is provided on the bottom side of the movable rocker plate 901 away from the fixed shaft. Each movable rocker plate 901 is connected to the connecting slide rod 95 through an independent auxiliary pull rope 904. At the same time, an cavity is provided in the auxiliary measuring plate 25 at the connecting slide rod 95. A fourth spring 94 is provided on the side of the cavity away from the movable rocker plate 901.

[0060] T-shaped limiting members 902 are installed at the middle of both ends of the movable rocker 901 and on the side adjacent to the fixed shaft. The T-shaped limiting members 902 are slidably disposed in the auxiliary measuring plate 25. The auxiliary measuring plate 25 has a first auxiliary slide groove on both sides of the movable cavity and at the corresponding auxiliary measuring plate 25.

[0061] The limiting structure 7 includes a turntable 72. A second rotating shaft is connected to one side of the turntable 72. The second rotating shaft is driven by a first servo motor 71. A T-shaped fixing member 76 is fixedly installed at the lower part of the middle of the other end of the turntable 72. A movable connecting member 73 is provided at the other end of the turntable 72 through the T-shaped fixing member 76. A second auxiliary slide groove is vertically opened in the movable connecting member 73. The width of the second auxiliary slide groove is the same as the outer diameter of the T-shaped fixing member 76.

[0062] Furthermore, movable rods 74 are fixedly installed at the middle of both ends of the movable connector 73. A rod assembly 75 is slidably mounted on the end of the movable rod 74 away from the turntable 72. A third auxiliary groove is formed within the movable rod 74 at the rod assembly 75. The rod assembly 75 includes a limiting slider 751, into which a limiting rod 752 is inserted. The limiting rod 752 is parallel to the pressing slider 5. The cross-sectional area of ​​the limiting slider 751 is larger than that of the limiting rod 752. A third through hole is formed within the limiting slider 751 at the limiting rod 752. T-shaped limiting blocks are symmetrically arranged on both sides of the third through hole. A fourth auxiliary groove is formed on each side of the limiting rod 752 at the adjacent T-shaped limiting blocks. The end face of the limiting rod 752 away from the pressing slider 5 is arc-shaped.

[0063] Meanwhile, a second movable cavity is provided in the auxiliary measuring plate 25 at the turntable 72 and the T-shaped fixing part 76, and a third movable cavity is provided in the auxiliary measuring plate 25 at the movable connecting part 73, and a sliding groove cavity is provided in the auxiliary measuring plate 25 at the movable rod 74.

[0064] The auxiliary measuring plate 25 has a first guide groove, a transition guide groove, and a second guide groove sequentially opened on one side of the slide cavity. The depth of the first guide groove is greater than the depth of the second guide groove. An inclined transition guide groove is provided between the first guide groove and the second guide groove.

[0065] The auxiliary measuring plate 25 has a locking cavity on both sides of the slide groove and at the corresponding first guide groove, and the cross-sectional area of ​​the locking cavity is the same as the cross-sectional area of ​​the limiting rod 752.

[0066] When the center of the T-shaped fastener 76 and the turntable 72 are on the same vertical line, both sets of insert rod assemblies 75 are located in the third auxiliary slide groove and on the side away from the turntable 72, and the limiting insert rod 752 of the insert rod assembly 75 is located in the second movable cavity.

[0067] Furthermore, when the hand grip plate is located at one end of the adjacent limiting auxiliary groove, its first spring 51 is in a deformed state, and at this time its auxiliary rod assembly is aligned with its locking cavity.

[0068] Meanwhile, it is worth noting that the second spring 81, the third spring 64, the fourth spring 94, and the fifth spring 903 are all equipped with damping components, which are not shown in the diagram. The model of the first laser rangefinder 41 is KJT-FG30, and the model of the second laser rangefinder module 42 is VL53L0X.

[0069] It is worth noting that the specific structure and working principle of the first laser rangefinder 41, the second laser rangefinder module 42, the first electric telescopic rod 3, the second servo motor and the hydraulic rod assembly, and the first servo motor 71 are all existing technologies that are currently publicly available on the market, and are not the main technical problems that this invention needs to solve, so they will not be described in detail.

[0070] It is also worth mentioning that when the first servo motor 71 rotates toward the fixed measuring rod 23, it is in forward rotation; when the first servo motor 71 rotates away from the fixed measuring rod 23, it is in reverse rotation. When the second servo motor rotates toward the second limiting component 92, it is in forward rotation; when the second servo motor rotates toward the first limiting component 91, it is in reverse rotation.

[0071] When the first servo motor 71 is in the initial position, its T-shaped fixing member 76 is on the same vertical line as the center of the turntable 72, and the T-shaped fixing member 76 is located below the second rotating shaft. The limiting rod 752 of its limiting structure 7 limits the adjacent pressing slider 5. When the second servo motor is in the initial position, the movable rocker plate 901 of its first limiting component 91 and second limiting component 92 are both in an inclined state.

[0072] Meanwhile, the initial state of the elastic block 61 is that the elastic block 61 is partially located outside the auxiliary measuring component 26, and its spring is in a deformed state, and its limiting protrusion is located in the middle of the heart-shaped guide groove 621 and on the side of the elastic block 61.

[0073] In this invention, when it is necessary to measure the pins of the male connector of the radio frequency connector to be tested, the male connector to be measured is placed below the measuring component 2, and the fixed measuring rod 23 of the measuring component 2 is initially positioned inside the male connector and above its pins by controlling the hydraulic rod assembly. Then, the measuring component 2 drives its movable block 22 to move through the first electric telescopic rod 3, so that the fixed measuring rod 23 and the movable measuring rod 24 are respectively located on both sides of the pins.

[0074] Continuing, control the hydraulic rod assembly to move its fixed measuring rod 23 and movable measuring rod 24 toward the male end until the bottom of the fixed measuring rod 23 and the bottom of the movable measuring rod 24 are in contact with the bottom of the male end. Then, drive its movable block 22 to move through the first electric telescopic rod 3 until the fixed measuring rod 23 is in contact with the outer wall of the pin. Then, measure the distance from the transmitting end to the corresponding auxiliary measuring plate 25 through the first laser rangefinder 41, where the height of the male end's pin = the reading of the first laser rangefinder 41 - the thickness of the auxiliary measuring plate 25.

[0075] When it is necessary to measure the outer diameter of the male connector pin, the first servo motor 71 is controlled to rotate forward, and the limiting rod 752 on the side away from the fixed measuring rod 23 moves along the transition guide groove into the first guide groove. Under the action of the second spring 81, one end of the limiting rod 752 moves away from the pressing slider 5 and loses its limiting effect on the pressing slider 5.

[0076] Simultaneously, the second servo motor is reversed, causing its movable pressing rod 93 to rotate. One end of the movable pressing rod 93 presses against the connecting slide rod 95 of the first limiting component 91. At this time, its fourth spring 94 is in a deformed state, and the movable rocker 901 of the second limiting component 92 rotates to a certain extent under the action of the fifth spring 903. The movable rocker 901 is in an inclined state, and at this time, the other end of its movable pressing rod 93 moves away from its second limiting component 92. The connecting slide rod 95 of the second limiting component 92 is in a free state under the fourth spring 94, causing its connecting slide rod 95 to move toward the movable pressing rod 93 and move its auxiliary pull rope 904, driving the movable rocker 901 to rotate and placing the movable rocker 901 in the movable cavity.

[0077] At the same time, the limiting rod 752 of the rod assembly 75 on the side of the limiting structure 7 away from the fixed measuring rod 23 is located in the first guide groove and loses its limiting effect on the pressing slider 5 on the side away from the fixed measuring rod 23. Meanwhile, the pressing slider 5 on the side away from the fixed measuring rod 23 moves towards the movable measuring rod 24 and presses against it under the action of the first spring 51.

[0078] At the same time, the limiting rod 752 of the rod assembly 75 on the side of the limiting structure 7 away from the fixed measuring rod 23 is located in the adjacent first guide groove, and loses its limiting effect on the pressing slider 5 on the side close to the fixed measuring rod 23. Meanwhile, the pressing slider 5 on the side close to the fixed measuring rod 23 moves towards the movable measuring rod 24 and presses against it under the action of the first spring 51 until the movable measuring rod 24 is basically in contact with the outer wall of its male pin.

[0079] Meanwhile, when the pressing slider 5 moves, the movable rocker plate 901 of its first limiting component 91 does not prevent the pressing slider 5 from moving toward the movable measuring rod 24. Through the setting of the movable rocker plate 901, when the pressing slider 5 retracts under the action of the first spring 51, its adjacent movable rocker plate 901 limits and blocks it, preventing the pressing slider 5 from retracting under the action of the first spring 51.

[0080] Simultaneously, the pressing slider 5 presses its elastic block 61, causing the elastic block 61 to move into the limiting groove, and its limiting protrusion slides along the heart-shaped guide groove 621. When the pressing slider 5 retracts under the action of the first spring 51, the pressing slider 5 loses its pressure on the elastic block 61, and the pressing slider 5 moves outward of the auxiliary measuring component 26 under the action of the third spring 64. At this time, its limiting protrusion slides along the heart-shaped guide groove 621 and moves away from the elastic block 61. When its limiting protrusion slides in the heart-shaped guide groove 621, the positioning rod rotates synchronously in the movable cavity and presses against the pressing slider 5 through the elastic block 61, causing its movable measuring rod 24 to further fit against the outer wall of the male pin. The distance from the emitter of the second laser ranging module 42 to the auxiliary measuring component 26 is measured through the second laser ranging module 42, where the measured value of the outer diameter of the male pin = the reading of the second laser ranging module 42 - the length of the second laser ranging module 42.

[0081] When it is necessary to measure the depth of the female connector's insertion hole, the female connector to be measured is placed below the measuring component 2, and the fixed measuring rod 23 is initially positioned inside the female connector and above its insertion hole by controlling the hydraulic cylinder component. Then, the measuring component 2 moves its movable block 22 by the first electric telescopic rod 3, so that the fixed measuring rod 23 and the movable measuring rod 24 are respectively located inside the insertion hole.

[0082] Then, the hydraulic rod assembly is controlled to move the fixed measuring rod 23 and the movable measuring rod 24 into the female head until the bottom of the fixed measuring rod 23 and the bottom of the movable measuring rod 24 are in contact with the bottom of the female head. The movable block 22 is driven by the first electric telescopic rod 3 to move until the fixed measuring rod 23 is in contact with the inner wall of the insertion hole. At this time, the bottom of the auxiliary measuring plate 25 of the measuring assembly 2 is in contact with the top of the female head insertion pin. The distance from the transmitting end to the auxiliary measuring plate 25 is measured by the first laser rangefinder 41, where the depth of the female head insertion hole = the reading of the first laser rangefinder 41 - the thickness of the auxiliary measuring plate 25.

[0083] When it is necessary to measure the inner diameter of the female connector's socket, the first servo motor 71 is controlled to reverse, and the limiting rod 752 on the side near the fixed measuring rod 23 moves along the transition guide groove into the first guide groove. Under the action of the second spring 81, one end of the limiting rod 752 moves away from the pressing slider 5 and loses its limiting effect on the pressing slider 5.

[0084] Simultaneously, the second servo motor is controlled to rotate forward, causing its movable pressing rod 93 to rotate. One end of the movable pressing rod 93 presses against the connecting slide rod 95 of the second limiting component 92. At this time, its fourth spring 94 is in a deformed state, and the movable rocker 901 of the second limiting component 92 rotates to a certain extent under the action of the fifth spring 903. The movable rocker 901 is in an inclined state, and at this time, the other end of its movable pressing rod 93 moves away from its first limiting component 91. The connecting slide rod 95 of the first limiting component 91 is in a free state under the fourth spring 94, causing its connecting slide rod 95 to move towards the movable pressing rod 93 and move its auxiliary pull rope 904, driving the movable rocker 901 to rotate and placing its movable rocker 901 in the movable cavity.

[0085] At the same time, the limiting rod 752 of the rod assembly 75 on the side of the limiting structure 7 near the fixed measuring rod 23 is located in the adjacent first guide groove and loses its limiting effect on the pressing slider 5 on the side near the fixed measuring rod 23. Meanwhile, the pressing slider 5 on the side near the fixed measuring rod 23 moves towards the movable measuring rod 24 and presses against it under the action of the first spring 51 until the movable measuring rod 24 is basically in contact with the inner wall of its female head insertion hole.

[0086] Meanwhile, when the pressing slider 5 moves, the movable rocker plate 901 of its second limiting component 92 does not prevent the pressing slider 5 from moving toward the movable measuring rod 24. Through the setting of the movable rocker plate 901, when the pressing slider 5 retracts under the action of the first spring 51, its adjacent movable rocker plate 901 limits and blocks it, preventing the pressing slider 5 from retracting under the action of the first spring 51.

[0087] Simultaneously, the pressing slider 5 presses its elastic block 61, causing the elastic block 61 to move into the limiting groove, and its limiting protrusion slides along the heart-shaped guide groove 621. When the pressing slider 5 retracts under the action of the first spring 51, the pressing slider 5 loses its pressure on the elastic block 61, and the pressing slider 5 moves to the outside of the auxiliary measuring component 26 under the action of the third spring 64. At this time, its limiting protrusion slides along the heart-shaped guide groove 621 and moves away from the elastic block 61. When its limiting protrusion slides in the heart-shaped guide groove 621, the positioning rod rotates synchronously in the movable cavity and presses against the pressing slider 5 through the elastic block 61, causing its movable measuring rod 24 to further fit against the inner wall of the female connector hole, and the distance from the emitter of the second laser ranging module 42 to the auxiliary measuring component 26 is measured through the second laser ranging module 42, and one side of the second laser ranging module 42 fits against the outer wall of the adjacent fixed measuring rod 23.

[0088] The measured value of the inner diameter of the female connector is equal to the reading of the second laser ranging module 42 plus (the diameter of the fixed measuring rod 23 plus the diameter of the auxiliary measuring component 26 plus the length of the second laser ranging module 42).

[0089] Specifically, when the height of the male connector pin is the same as the depth of the female connector hole, the male connector pin height matches the depth of the female connector hole, and the measured value of the inner diameter of the female connector hole is the same as the measured value of the outer diameter of the male connector pin, the male and female connectors can be smoothly connected.

[0090] When it is necessary to measure a new male or female connector, first hold the hand grip of the sliding block 5 and move it until the hand grip is located at one end of the adjacent limiting auxiliary groove. At this time, the first spring 51 is in a deformed state, and the auxiliary rod assembly is aligned with the locking cavity, and the first servo motor 71 is in the initial position.

[0091] In this invention, the test unit 11 of the test device body 1 can simultaneously measure the pin height and outer diameter of the male connector of the RF connector, or simultaneously measure the depth and inner diameter of the socket of the female connector, thereby improving measurement efficiency. Through the cooperation of the hydraulic rod assembly, the first electric telescopic rod 3, and the auxiliary pressing assembly 6, the measuring assembly 2 can accurately contact and fit with the part being measured, ensuring the accuracy of the measurement data.

[0092] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
