[0030] The connecting pin 33 includes an insertion pin 331, one end of which is provided with an introduction groove 332, the other end of which is fixedly connected to a handle 334, an outer wall of the insertion pin 331 is provided with a sliding groove 333, the inner wall of the first positioning frame 31 and the outer wall of the fixed protrusion 32 are both slidably connected to the outer wall of the insertion pin 331, the inner wall of the second positioning frame 34 and the outer wall of the sliding block 35 are both slidably connected to the outer wall of the insertion pin 331, and the outer wall of the insertion pin 331 is slidably connected to the outer wall of the anti-drop plate 36 through the sliding groove 333 Dynamic connection, when in use, the guide groove 332 of the insertion pin 331 is convenient for insertion. After the insertion pin 331 is inserted, the fixed protrusion 32 and the sliding block 35 slide on the sliding groove 333, and then the insertion pin 331 is rotated by twisting the handle 334, so that the fixed protrusion 32 and the sliding block 35 enter the groove of the sliding groove 333, thereby completing the preliminary fixation of the insertion pin 331, and then the anti-slip plate 36 is set with a small protrusion entering the sliding groove 333 to prevent rotation, and the position is fixed by the fixing bolt 37 to prevent the insertion pin 331 from falling out.

[0031] Working principle:

[0032] First, place the lower base 11 of the lower detection device 1 below the press, and then fix the position of the lower base 11 by bolts and fixing grooves 18, wherein the reinforcing ribs 13 on the lower base 11 enhance its structural strength, and the through grooves 12 and square blind holes 19 are arranged to reduce the overall mass of the lower base 11 while maintaining the overall structural strength of the lower base 11, and at the same time can improve the stress distribution of the mold, reduce stress concentration, and enhance the structural stability of the mold, so that it is not easy to break when subjected to pressure and impact. The label groove 14 is used to mark and distinguish different detection positions, and each label groove 14 position corresponds to a lower detection block 16, wherein the row sequence is arranged in Arabic numerals and the column sequence is arranged in letters. Before use, adjust the lower balance block 17 to make the height of all the lower balance blocks 17 consistent, thereby simulating the vehicle mold surface, and then place the lead block in the placement hole 165 of the lower detection block 16, and then install the upper detection device 2, the weight reduction groove 2 in the upper base 21 2 can reduce the overall weight, the upper base 21 is fixed to the output end of the press through the connecting groove 23, and then the upper balancing block 25 is adjusted so that all the upper balancing blocks 25 are flush, wherein the upper balancing block 25 and the lower balancing block 17, the upper detection block 24 and the lower detection block 16, and the upper connecting device 3 and the lower connecting device 4 have the same structure and function, and are numbered to distinguish the fixed position and the connection position for the convenience of distinguishing. After the upper base 21 is installed on the press, the press applies pressure, and the upper detection device 2 makes the upper detection device 2 move stably by making the positioning plate 26 of the upper detection device 2 slide with the limit block 15 of the lower detection device 1. The upper detection block 24 is close to the lower detection block 16 at this time. When the upper balancing block 25 and the lower balancing block 17 are in contact, the lead block is squeezed and deformed, and then the upper detection device 2 is removed, and the height of the lead block is measured with a caliper to obtain the required value. The cooperation between the upper detection device 2 and the lower detection device 1 can comprehensively and accurately detect the concavity of the mold.

[0033] The structural design of the lower balancing block 17 is convenient for adjusting the height. The purpose of simulating the automobile mold surface is achieved by adjusting the lower balancing block 17. When adjusting, the height of the lower balancing block 17 is adjusted by rotating the second hexagonal column 173 in the connecting hole 172 in the balancing plate 171 and using the second thread groove 174 to be threadedly connected to the lower base 11, so that all the lower balancing blocks 17 reach the same height, thereby simulating the mold surface; the structural design of the lower detection block 16 is convenient for adjustment and fixation. The height of the lower detection block 16 is adjusted by rotating the first hexagonal column 163 in the linkage hole 162 in the detection column 161 and using the first thread groove 164 to be threadedly connected to the lower base 11. The lower detection block 16 moves stably under the dual guidance of the limit column 166 and the first hexagonal column 163, and cooperates with the lower balancing block 17 to simulate the mold surface. Since the upper balancing block 25 and the lower balancing block 17 have the same structure, and the upper detection device 2 and the lower detection device 1 have the same structure, the upper detection device 2 can also be adjusted to simulate the mold surface.

[0034] The upper connecting device 3 is set, and the object to be connected is placed between the first positioning frame 31 and the second positioning frame 34, and then connected and fixed by the connecting pin 33, and fixed and anti-slipped by the anti-slip plate 36 and the fixing bolt 37 to ensure the stability of the connection. When in use, the introduction groove 332 of the insertion pin 331 is convenient for insertion. After the insertion pin 331 is inserted, the fixing protrusion 32 and the sliding block 35 slide on the sliding groove 333, and then the insertion pin 331 is rotated by twisting the handle 334 so that the fixing protrusion 32 and the sliding block 35 enter the groove of the sliding groove 333 to complete the preliminary fixation of the insertion pin 331, and then the small protrusion of the anti-slip plate 36 is set to enter the sliding groove 333 to prevent rotation, and the position is fixed by the fixing bolt 37 to prevent the insertion pin 331 from falling out. The position of the object connected in the upper connecting device 3 is stabilized through secondary fixation.
