Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0026] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features; in the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0027] Referring to Figure 1-6 , the present utility model provides a FA device positioning and clamping device, including a base 1; a fixed clamping block 2 is provided on the base 1; a first movable jaw 3 and a second movable jaw 5 are respectively provided on both sides of the fixed clamping block 2 and are matched with it; a clamping station for the transmitting end FA 9 is provided between the first movable jaw 3 and the fixed clamping block 2; a clamping station for the receiving end FA 10 is provided between the second movable jaw 5 and the fixed clamping block 2. The back and bottom of the base 1 are preferably designed as high-precision support planes. When in use, such as Figure 1As shown, place the entire FA device on the base 1. Place the transmitting end FA9 and the receiving end FA10 in their corresponding work positions. Activate the first movable jaw 3 and the second movable jaw 5, which cooperate with the side wall of the fixed clamping block 2 to clamp and fix the receiving end FA10 and the transmitting end FA9. Then place the entire device on the detection table of the three-dimensional detector, and adjust the contact surface between the base 1 and the detection table according to the dimensions to be measured, and sequentially complete the fiber pitch measurement in the horizontal and vertical dimensions. After the detection is completed, release the first movable jaw 3 and the second movable jaw 5, and take out the FA device.

[0028] Further, as Figure 5 shown, the above-mentioned first movable jaw 3 includes a first jaw body 301; one end of the first jaw body 301 is connected with a first clamping block 303 that matches the fixed clamping block 2, and the other end is connected to the base 1 through a first elastic member. The relative distance between the first clamping block 303 and the fixed clamping block 2 is adjusted by the expansion or compression of the first elastic member, and pressure is provided for FA clamping. The first elastic member preferably includes a first spring 4; one end of the first spring 4 is fixedly connected to the base 1, and the other end is fixedly connected to the first jaw body 301. In the initial state, the first spring 4 is not subjected to an external force, and at this time, the relative distance between the first clamping block 303 and the fixed clamping block 2 is small. When in use, apply a force to the first spring 4 to compress it. The lower end of the first jaw body 301 approaches the base 1 along with the spring, and the upper end connected with the first clamping block 303 moves in the opposite direction, away from the fixed clamping block 2, exposing the clamping position of the transmitting end FA9. After placing the transmitting end FA9 in the work position, release the first spring 4, and under the action of the resilience force, the first clamping block 303 and the fixed clamping block 2 cooperate to clamp the transmitting end FA9.

The first hinge portion 302 protrudes on the adjacent surfaces of the first jaw body 301 and the base 1, driving the first jaw body 301 and the first clamping block 303 to rotate around the first rotating shaft 101 together with the compression or rebound of the first elastic member.

[0030] Optionally, the structure of the second movable jaw 5 is the same as that of the first movable jaw 3, as Figure 6 shown, that is, the second movable jaw 5 includes a second jaw body 501; one end of the second jaw body 501 is connected with a second clamping block 503 that matches the fixed clamping block 2, and the other end is connected to the base 1 through a second elastic member. The second elastic member preferably includes a second spring 6.

[0031] Furthermore, a second hinged portion 502 is provided at one end of the second clamping jaw body 501 close to the second clamping block 503 ; a second rotating shaft 102 is provided on the base 1 ; the second hinged portion 502 is sleeved on the second rotating shaft 102 and rotates around the second rotating shaft 102 .

[0032] In a detailed implementation, the transmitting terminal FA9 clamping station is provided with a first limiting groove 7 matching the transmitting terminal FA9; the receiving terminal FA10 clamping station is provided with a second limiting groove 8 matching the receiving terminal FA10. Figure 4 As shown, the first limiting groove 7 and the second limiting groove 8 are open limiting grooves. In addition to sharing a side wall with the fixed clamp block 2, a side wall is only set on the lower side to limit the height of FA so that the position of FA is consistent each time to ensure detection consistency. No side wall is set on the side away from the fixed clamp block 2 to avoid interference with the clamping of the movable clamping claw, and no side wall is set on the upper side to facilitate the detection of the vertical dimension of FA.

[0033] The utility model also provides a FApitch detection device including the above-mentioned FA device positioning and clamping device, and the device also includes a three-dimensional detector. The FA device positioning and clamping device can be detachably mounted on the detection table of the three-dimensional detector. After the FA device positioning and clamping device loads the FA device, the FA device positioning and clamping device is mounted on the detection table of the three-dimensional detector to measure the fiber pitch size of each of the transmitting end FA 9 and the receiving end FA 10.
