[0041] Specifically, two first positioning holes 210 and two second positioning holes 230 are respectively provided at both ends of the part 200, and the two second positioning holes 230 are respectively provided close to the two first positioning holes 210. Two positioning posts 21 extending in the up-down direction are respectively provided on the upper end surfaces of the two support blocks 13. In the process of placing the part 200 in the placement area 11 in the horizontal direction, the two second positioning holes 230 on the part 200 can be aligned with the two positioning posts 21 on the base 1 respectively, and then the part 200 can be placed on the base 1, so that the preliminary installation and positioning of the part 200 on the base 1 can be achieved through the positioning cooperation between the two second positioning holes 230 and the two positioning posts 21.
[0042] The upper end surface of the support block 13 is provided with a positioning column 21. The specific arrangement of the positioning column 21 is not particularly limited.

A mounting hole extending in the up-down direction is provided on the upper end surface of each support block 13, and a second positioning pin 2b is inserted into the mounting hole, and the lower end of the second positioning pin 2b is inserted into the mounting hole, and the upper end of the second positioning pin 2b extends upward out of the mounting hole to form a positioning column 21.
[0043] See also Figures 1 to 4 Two first positioning pins 2a are provided corresponding to the two first insertion holes 12, and the lower end of each first positioning pin 2a is used to pass through the first positioning hole 210 and then be inserted into a corresponding first insertion hole 12, so as to position the part 200 through the two first positioning pins 2a.

Two first clamps 6a are provided on the upper surface of the base 1, and the two first clamps 6a are respectively used to clamp and cooperate with the holding ends of the two first positioning pins 2a. The two first positioning pins 2a are detachably provided at the two first clamps 6a by clamping and fixing, and the two first clamps 6a are used to store the two first positioning pins 2a.
[0046] For further information, see Figures 1 to 4 In this embodiment, the two first clips 6 a are arranged on a side of the placement area 11 that is away from the movable seat 4 in the longitudinal direction.
[0047] See also Figures 1 to 4 Two clamping mechanisms 3 are arranged in the placement area 11, and each clamping mechanism 3 has a clamping state abutting against the upper side of one end of the part 200 in the lateral direction, and a releasing state opposite to the clamping state, and is used to clamp and fix the two ends of the part 200 in the lateral direction through the two clamping mechanisms 3 after the part 200 is positioned.
[0048] Specifically, each clamping mechanism 3 includes a pressure head and a pressure head driving mechanism, and the pressure head driving mechanism is coupled to the pressure head power, and is used to drive the pressure head through the pressure head driving mechanism, so that the pressure head has a clamping position and a release position. When the pressure head is in the clamping position, the pressure head abuts against the upper side of the part 200, and the clamping mechanism 3 is in a clamping state. When the pressure head is in the release position, the pressure head and the part 200 are staggered upward and downward, and the clamping mechanism 3 is in a release state.
[0049] After two first positioning pins 2a are inserted into the two first positioning holes 210 of the part 200, two clamping mechanisms 3 are used to clamp and fix the two ends of the part 200 in the lateral direction, so as to precisely position and fix the part 200 in the placement area 11. The clamping mechanism 3 can be a quick clamp or the like.
[0050] Optionally, see Figures 1 to 4In this embodiment, the part of the clamping mechanism 3 used to abut the part 200 is provided with a boss 31, so as to abut the part 200 through the boss 31. The pressing head of the clamping mechanism 3 is provided with a boss 31, and when the pressing head is in the clamping position, the pressing head abuts the part 200 through the boss 31, which is conducive to pressing the part 200 flatly through the pressing head.

The lower ends of the plurality of first detection pins 5a are used to be respectively inserted into the plurality of first assembly holes 220 to detect the position of the plurality of first assembly holes 220.
[0053] Specifically, after using two clamping mechanisms 3 to precisely position and fix the part 200 in the placement area 11, the movable seat 4 is moved toward the part 200 so that the lower end of a first detection pin 5a on the movable seat 4 is opposite to a corresponding first assembly hole 220 up and down, thereby completing the movable adjustment of the movable seat 4, and then pressing multiple first detection pins 5a in sequence, so as to quickly detect whether the multiple first assembly holes 220 of the part 200 are smooth. If there is interference, it means that the part 200 is unqualified. If there is no interference, it means that the part 200 is qualified.
[0054] Optionally, see Figures 1 to 4 In this embodiment, a handle 43 is provided at one end of the movable seat 4 away from the placement area 11 in the longitudinal direction, and a plurality of first detection pins 5a are provided at intervals in the transverse direction at one end of the movable seat 4 close to the placement area 11 in the longitudinal direction.

[0055] Optionally, see Figures 1 to 4In this embodiment, a base 14 is provided on the base 1, and the base 14 is located on one side of the placement area 11 in the longitudinal direction. The base 14 is provided with a guide rail 15 extending in the longitudinal direction, and the movable seat 4 can be arranged on the guide rail 15 so as to be movable and adjustable in the longitudinal direction. The movable seat 4 is arranged on the base 14, so that other components on the base 1 can avoid interference with the sliding of the movable seat 4, and the guide rail 15 can realize the sliding guidance of the movable seat 4.
[0056] A limiting structure is usually provided between the guide rail 15 and the movable seat 4, so that after the movable seat 4 is adjusted, the movable seat 4 is limited by the limiting structure. The specific setting method of the limiting structure can be set according to actual conditions. For example, the limiting structure can be a locking screw, which is installed on the guide rail 15. After the movable seat 4 is adjusted, the tail of the locking screw is pressed against the movable seat 4 to limit the movable seat 4.

[0058] The utility model places a part 200 on a base 1, inserts two first positioning pins 2a into two first positioning holes 210 of the part 200 respectively, then uses two clamping mechanisms 3 to precisely position and fix the part 200, and then moves the movable seat 4 toward the part 200. After the movable seat 4 is positioned, multiple first detection pins 5a are pressed in sequence to quickly detect whether multiple first assembly holes 220 of the part 200 are smooth, so as to quickly determine whether the part 200 is qualified. The operation of the part assembly hole position inspection fixture 100 is simple and fast, and the comprehensive detection cost is low.

If there is interference at any second detection pin 5b, that is, the insertion end of the second detection pin 5b (that is, the lower end of the second detection pin 5b) cannot enter the corresponding second plug hole 16 from the second detection pin 5b, it means that the part 200 is unqualified.
[0061] For further information, see Figures 1 to 4 In this embodiment, a positioning block 17 is provided in the placement area 11, and the positioning block 17 is used to support one end of the part 200 away from the movable seat 4 in the longitudinal direction, and a plurality of second plug holes 16 are provided on the upper end surface of the positioning block 17. The positioning block 17 and two supporting blocks 13 are provided on the upper surface of the base 1, and the three ends of the part 200 are supported by the positioning block 17 and the two supporting blocks 13, which is conducive to stably placing the part 200 in the placement area 11.

The three processing reference holes 19 are used as a reference for setting the first socket 12, the second socket 16, the second positioning pin 2b, and the first detection pin 5a.
[0067] The working principle of the part assembly hole position inspection fixture 100 can be as follows: 1. Place the part 200 on the base 1, use two first positioning pins 2a to insert them into the two first positioning holes 210 of the part 200 respectively, and then use two clamping mechanisms 3 to accurately position and fix the part 200; 2. Move the movable seat 4 toward the part 200, and then use the limit pin 41 to press down for precise positioning; 3. After positioning is completed, press multiple first detection pins 5a in turn to quickly detect whether the multiple first assembly holes 220 of the part 200 are smooth. If there is interference, it means that the part 200 is unqualified; 4. Take three second detection pins 5b and put them into the multiple second assembly holes 240 in turn. According to the three-point positioning principle, a single quick detection of the position of the second assembly hole 240 is performed to determine whether it is smooth. If there is interference, it means that the part 200 is unqualified.
[0068] The operation of the part assembly hole position gauge 100 is simple and fast, and the comprehensive inspection cost is low. It only takes 10 seconds to determine whether a single part 200 meets the drawing requirements, and it can be fully inspected in batch production. Ordinary personnel only need a short training to master the use of the part assembly hole position gauge 100. The life of a set of part assembly hole position gauge 100 is about 200,000 pieces / time, and the inspection cost of a single unit is about 0.01 yuan.
