The positioning assembly 426 is used to determine a minimum spacing between the first block 423 and the second block 424.

Referring to fig. 5 and 6, in some embodiments of the invention, the mounting base 410 is fastened to the third mounting plate 340 by screws, the mounting base 410 includes a bottom plate 411, a supporting block 412 and a top plate 413, the top plate 413 is located above the bottom plate 411, two ends of the supporting block 412 are fastened to the top plate 413 and the bottom plate 411 respectively, and the supporting block 412 is provided with a plurality of blocks.

Therefore, during the process of the pin 810 bending upward or downward to enter the calibration opening 614, the pin is constrained by the first calibration surface 613 or the second calibration surface 615 to deform and no longer bend upward or downward.

Referring to fig. 3 to 5, in some embodiments of the invention, the limiting member 422 includes a first pressing block 621 and a second pressing block 622, the first pressing block 621 and the second pressing block 622 are both fastened and fixed to the left end of the top plate 413 by screws, and the lower end of the first pressing block 621 is located at the front side of the lower end of the second pressing block 622.

Thus, the first clamping arm 631 and the second clamping arm 638 are both rotatably connected with the mounting seat 410.

The first clamping block 423 is fixed to the left end of the first clamping arm 631 by screws, and is located at the front side of the first clamping arm 631. The second clamping block 424 is fixed to the left end of the second clamping arm 638 by screws, and is located at the rear side of the second clamping arm 638. The first clamping block 423 and the second clamping block 424 are arranged oppositely, and when the first clamping arm 631 and the second clamping arm 638 clamp or open, the first clamping block 423 and the second clamping block 424 can be close to or separated from each other.

The first roller 632 is rotatably connected to an end (i.e. right end) of the first arm 631 away from the first clamping block 423, and the second roller 637 is rotatably connected to an end (i.e. right end) of the second arm 638 away from the second clamping block 424.

The right end of the first sliding plate 634 and the right end of the second sliding plate 633 are both fixedly connected with the push plate 636, and the output end of the first driving element 635 is connected with the push plate 636. Thus, when the first driving element 635 drives the first and second sliding plates 634 and 633 to the left, the first and second clamp arms 631 and 638 are clamped.

The first drive element 635 may be selected from a pneumatic cylinder or a hydraulic cylinder.

Specifically, the elastic element is a compression spring, the first clamping arm 631 is fixed with a sleeve 641, the compression spring is inserted into the sleeve 641, the second clamping arm 638 is fixed with a baffle 643 through a screw, and the baffle 643 abuts against the compression spring. When the first and second clamp arms 631 and 638 are clamped, the compression spring is compressed, and when the first and second sliding plates 634 and 633 move to the right, the compression spring is deformed again, and the first and second clamp arms 631 and 638 are spread.

In addition, the elastic member may also be a torsion spring, one pin of the torsion spring abuts against the first clamping arm 631, and the other pin of the torsion spring abuts against the second clamping arm 638.

In another embodiment, an inclined first kidney-shaped hole may be formed in the first sliding plate 634, an inclined second kidney-shaped hole may be formed in the second sliding plate 633, a right end of the first clip arm 631 slides in the first kidney-shaped hole, and a right end of the second clip arm 638 slides in the second kidney-shaped hole. By driving the first and second sliding plates 634 and 633 to slide in the left and right directions, the clamping or spreading of the first and second clamp arms 631 and 638 can be directly achieved without providing an elastic member.

Referring to fig. 8 and 9, to adjust the minimum spacing between the first and second shaping surfaces 661, a positioning assembly 426 is provided. The positioning assembly 426 includes a first positioning block 651, a second positioning block 652, a fixing block 653, a second rotating shaft 654, a second micrometer 655 and a first micrometer 656. The fixing base 653 is fixed to the top plate 413 by a screw lock, the first micrometer 656 includes a first micrometer screw 671 and a first fixed scale portion 672, the first fixed scale portion 672 is fixed to the fixing base 653, and the first micrometer screw 671 and the first fixed scale portion 672 are in threaded fit. The first positioning block 651 is rotatably connected to the fixing base 653 through the second rotating shaft 654, a lower end of the first positioning block 651 can abut against the first sliding plate 634, and an upper end of the first positioning block 651 abuts against the first micrometer screw 671.

Therefore, by adjusting the extension length of the first micrometer screw 671, the rotation position of the first positioning block 651 can be changed, and the limit position of the first sliding plate 634 capable of sliding leftward can be adjusted, so that the final clamping position of the first clamping arm 631 can be adjusted.

The fitting relationship between the second micrometer 655 and the second positioning block 652 is similar to the fitting relationship between the first micrometer 656 and the first positioning block 651, and will not be described again here.

By adjusting the minimum spacing between the first shaping surface 661 and the second shaping surface, different widths of the pins 810 can be accommodated, avoiding improper adjustment or over-clamping of the pins 810.

In addition, the first positioning block 651 is provided with a groove 662, and the groove 662 can be retracted from the alignment block 612, so that the first shaping surface 661 can enter the alignment opening 614, thereby aligning the pin 810 in place.

In conjunction with the above, referring to fig. 2, 5 and 7, after the relay 800 with the pin 810 is placed on the carrier platform 100, the second driving assembly 200 inserts the pin 810 on the front side of the relay 800 into the calibration opening 614. Because the distance between the first alignment surface 613 and the second alignment surface 615 gradually decreases along the direction of inserting the pin 810 into the alignment opening 614, the pin 810 will complete alignment in two bending directions (the pin will not bend upward or downward) during the process of inserting the pin 810 into the alignment opening 614. After the pin 810 is inserted into the alignment opening 614, the first and second shaping surfaces 645 are brought close to the pin 810 and engage the pin 810 under the action of the first driving assembly 425, and alignment in two other bending directions is completed (the pin is not bent to the left or to the right). At this point, the pins are fully aligned, and then the first and second shaping surfaces 645 are separated from the pins 810 by the first driving assembly 425, and the second driving assembly 200 disengages the pins 810 from the alignment openings 614, completing the alignment operation of the pins 810 on the front side.

Then, the third driving assembly 300 moves the calibration assembly 400 backward a certain distance to align the pin 810 at the front side of the relay 800 with the calibration hole 614, and then repeats the above operations to complete the calibration of the pin 810 at the rear side. In the whole calibration process, the operation is labeling and automatic, the calibration efficiency is high, and the consistency of pins is good.

Referring to fig. 2, in a further embodiment of the present invention, 4 calibration units 420 are provided in the front-rear direction, and 4 relays 800 are also placed on the loading platform 100 in the front-rear direction. Therefore, the pin calibration device can complete the pin calibration of the 4 relays 800 at one time, and the calibration efficiency is high.

Of course, the number of the calibration units 420 may be set according to needs, for example, the number of the calibration units 420 may also be 3, 5 or other numbers.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
