[0038] Reference Figure 1-6A pin detection fixture includes two product bodies 10, two displacement sensors 1, a support shell 11, and a mounting plate 2. The mounting plate 2 is bolted to the upper side of the support shell 11. The support shell 11 and the mounting plate 2 form a bottom platform. Corresponding buttons and switches are installed on the support shell 11, and the electronic components required by the device are installed inside the support shell 11 for easy use. Four feet are installed on the lower side of the support shell 11 to buffer and support the device. The product bodies 10 are located on the upper side of the mounting plate 2, and the displacement sensors 1 are installed on the lower side of the mounting plate 2. The upper side of the mounting plate 2 has an A-hole, through which the detection rod of the displacement sensor 1 can pass.

The fixture also includes: two A-clamps 3, two A-connecting blocks 4, two pressure plates 5, a connecting plate 6, two connecting parts 7, a lifting unit 8, and two linkage units 9.

[0039] A clamp 3 is provided with a clamp 12 on its upper side, and the product body 10 is located between clamp 3 and clamp 12;

[0040] The connecting part 7 is located between clamp A 3, clamp B 12, and mounting plate 2. The connecting part 7 includes four connecting bolts 71. Clamp B 12 has rotating holes at its four upper corners, allowing the connecting bolts 71 to rotate within these rotating holes. Clamp A 3 has A mounting holes and two A threaded holes at its four upper corners. Mounting plate 2 has four B threaded holes and two B through holes on its upper side. A positioning cylinder 72 is installed inside the A mounting holes and mounted on the upper side of mounting plate 2. The connecting bolts 71 are detachably connected to the positioning cylinder 72 and the inner side of the B threaded holes via a threaded engagement shell. A positioning bolt 73 is located inside the B through holes and engages with the A threaded holes. The inner side of the hole is detachably connected by threads. Now, clamp A 3 is installed on the mounting plate 2 through positioning cylinder 72. Then, using a special device, four connecting bolts 71 are rotated simultaneously to install clamp B 12 on the upper side of clamp A 3. The height of clamp B 12 on clamp A 3 can be adjusted as needed. Clamp A 3, together with connecting block A 4, can position the product body 10. The product body 10 can be compressed and deformed. When the deformation limit is reached, clamp B 12 can limit the upper outer part of the product body 10, reducing the probability of damage to the product body 10 and improving the inspection quality of the product body 10.

[0041] The pressure plate 5 is located on the upper side of the product body 10; the connecting plate 6 is located on the upper side of the two pressure plates 5, and two support plates 13 are installed on the rear side of the connecting plate 6. The support plates 13 are detachably connected to the upper side of the mounting plate 2.

[0042] The lifting unit 8 is located between the connecting plate 6 and the two pressure plates 5. The lifting unit 8 includes two electric push rods 81. A B connecting block 82 is installed on the upper side of the pressure plate 5. Two reinforcing blocks 84 connect the pressure plate 5 and the B connecting block 82. The B connecting block 82 improves the connection strength between the B connecting block 82 and the pressure plate 5. The shaft end of the electric push rod 81 is connected to the upper side of the B connecting block 82. A buffer block 86 is installed on the lower side of the pressure plate 5. A limit block 87 is provided on the lower side of the buffer block 86. The limit block 87 is connected to the upper side of the mounting plate 2. The buffer block 86 and the limit block 87 limit the downward movement of the pressure plate 5, preventing the pressure plate 5 from pressing down excessively, reducing the probability of pressure damage to the product body 10, and improving the inspection quality. A C-shaped sliding surface is provided on the outer side of the pressure plate 5. The guide plate 83 and the C-shaped guide plate 83 are detachably connected to the upper side of the mounting plate 2 and the rear side of the connecting plate 6. The pressure plate 5 has positioning grooves on both the left and right sides. Two positioning plates 85 are fixed inside the C-shaped guide plate 83. The positioning plates 85 can slide inside the positioning grooves. The positioning plates 85 guide and position the pressure plate 5, making the movement of the pressure plate 5 within the C-shaped guide plate 83 more stable. The electric push rod 81 is installed on the front side of the connecting plate 6. The electric push rod 81 is connected to the power supply and the controller through wires. The electric push rod 81 carries the pressure plate 5 up and down within the C-shaped guide plate 83 through the B connecting block 82, so that the pressure plate 5 presses on the product body 10, causing the product body 10 to change, realizing automatic detection of it, and improving the detection efficiency of the device.

[0043] A connecting block 4 is located inside A clamp 3, and A connecting block 4 is detachably connected to the upper side of mounting plate 2 by bolts;

[0044] The linkage unit 9 is located between the A connecting block 4 and the displacement sensor 1. The linkage unit 9 includes an A spring 91 and an A sliding plate 92. The A connecting block 4 has an A sliding hole on its lower side and two B sliding holes on its upper side. The A sliding hole and the B sliding holes are connected. An A sliding cylinder 93 is fixed to the lower side of the A sliding plate 92, and two contact rods 94 are fixed to the upper side of the A sliding plate 92. The A sliding plate 92 and the A sliding cylinder 93 can slide inside the A sliding hole, and the contact rods 94 can slide inside the B sliding holes. An A limiting ring 95 is provided on the lower side of the A sliding cylinder 93. The A limiting ring 95 is installed inside the A sliding hole. An auxiliary rod 96 slides inside the A limiting ring 95 and is fixedly connected to the lower side of the A sliding plate 92. The A spring 91 is located inside the A sliding cylinder 93 and between the A sliding plate 92 and the A limiting ring 95. When the pressure plate 5 presses on the product body 10, causing the product body 10 to deform, the product body... When the body 10 deforms, it moves along with the pins inside the product body 10. At the same time, the pins come into contact with the contact rod 94 and press the contact rod 94 down. The contact rod 94 moves down with the auxiliary rod 96 through the sliding plate A 92, so that the auxiliary rod 96 comes into contact with the detection rod on the displacement sensor 1 and moves together. The displacement sensor 1 determines the displacement of the pins when the product body 10 deforms, thereby determining whether the pins of the product body 10 are installed in place. If the pins are not installed, it can be determined by the displacement, which can detect the pins of the product body 10 more quickly and improve the detection efficiency. When the product body 10 is reset, the contact rod 94 automatically resets upward under the action of the spring A 91. At the same time, the sliding cylinder A 93 and the sliding hole A have damping, so the contact rod 94 will not reset quickly after resetting upward, which improves the stability of the device operation.

[0045] An auxiliary reset part 97 is provided between the displacement sensor 1 and the mounting plate 2. The auxiliary reset part 97 includes a B spring 971 and a B sliding cylinder 972. The B sliding cylinder 972 can slide inside the A through hole. B limiting rings 973 are provided on both the upper and lower sides of the B sliding cylinder 972. The detection rod on the displacement sensor 1 can slide inside the B limiting rings 973. The B spring 971 is located between the lower side of the B sliding cylinder 972 and the B limiting rings 973. After the product body 10 is reset, the detection rod on the displacement sensor 1 will follow and reset upward. The B spring 971 will provide assistance for the reset, making the reset of the detection rod on the displacement sensor 1 more convenient. At the same time, even after the displacement sensor 1 has been used for a long time, it can still be reset to the position, which improves the service life of the device. In addition, the B sliding cylinder 972 and the A through hole have damping, which prevents the B sliding cylinder 972 from sliding back to the reset position quickly in the A through hole, thus improving the stability of the device operation.
