[0018] like Figures 1 to 7As shown, a pin hole position vertical measuring gauge comprises a measuring seat main body structure 1, a main body avoidance matching groove 2 which opens upward and completely penetrates the overall rear side is provided on the front side of the measuring seat main body structure 1, a first main body placement groove 3 which opens to the left is provided on the left side of the main body avoidance matching groove 2, a main body placement detection avoidance groove 4 which opens to the right is provided on the right side of the main body avoidance matching groove 2, a workpiece to be detected is placed at the positions of the first main body placement groove 3 and the main body placement detection avoidance groove 4, a avoidance matching groove is provided at the front end position on the left side of the main body avoidance matching groove 2, an assembly-level inverted L-shaped limiting pressure plate 5 is provided at the position of the avoiding matching groove, the limiting pressure plate 5 is connected to the measuring seat main body structure 1 through a pressure plate fastening bolt 6, a detection measuring groove 7 which is evenly distributed on the left and right and completely penetrates the overall front and rear direction and opens upward is provided at the front position of the main body placement detection avoidance groove 4, the position of the detection measuring groove 7 is matched with a measuring pin 8, and the detection measuring groove 7 is processed in stages, and can simultaneously meet the detection of multiple hole positions when in use, and can also meet the detection of pin shafts of different specifications, and has greater flexibility when in use. It adopts a brand-new structural design, and can detect the verticality of the hole position in the vertical direction on the pin shaft when in use, which solves the problem that the prior art cannot directly detect, and ensures the accuracy of the pin hole position, so that the pin shaft can be safer and more durable in later use. It is relatively convenient to use, and can be used with pin shafts of various specifications for detection as needed, and is more flexible in use. When measuring, first use the graded measuring pin to detect the size of the pin shaft aperture, select a measuring pin that is close to the size of the pin shaft aperture and can smoothly pass through the pin shaft aperture, put the pin shaft into the pin shaft reference positioning groove of the measuring seat, and insert the measuring pin through the measuring groove on one side of the measuring seat into the measuring groove on the other side of the measuring seat. If it can pass smoothly, it is qualified, and the size of the verticality of the pin hole position can be roughly determined by the size of the graded measuring groove of the measuring seat and the size of the measuring pin.
