Detailed Description
As shown in fig. 1 and 2, a cylinder end face hole site inspection tool comprises a gauge substrate 1, a first positioning pin 2, a second positioning pin 4, a second screw hole pin 5, two handles 7, a first screw hole pin 3 and two via hole pins 6; the inspection tool base plate 1 plays a role in assembling other parts, the first positioning pin 2 and the second positioning pin 4 are assembled on the inspection tool base plate 1 through interference connection to play a role in positioning reference, the second screw hole pin 5 and the first screw hole pins 3 are assembled on the inspection tool base plate 1 through interference connection to play a role in screw hole position inspection, the two via hole pins 6 are assembled on the inspection tool base plate 1 through interference connection to play a role in via hole position inspection, the two handles 7 are assembled on the inspection tool base plate 1 through threaded connection, an operator inspects the handheld effect, and the positions of the first positioning pin 2, the second positioning pin 4, the first screw hole pin 3, the second screw hole pin 5 and the via hole pin 6 correspond to the positions of the first positioning pin hole 8, the second positioning pin hole 10, the first screw hole 9, the second screw hole 11 and the via hole 12 of the cylinder body.
The two handles 7 are respectively arranged at two ends of the checking fixture substrate 1.
The handle 7 is arranged on one side face of the checking fixture substrate 1, and the first positioning pin 2, the second positioning pin 4, the first screw hole pin 3, the second screw hole pin 5 and the via hole pin 6 are arranged on the other side face of the checking fixture substrate 1.
The gauge base plate 1 is a large semicircular ring plate. The middle hole of the checking fixture base plate 1 has the function of reducing weight.
The working method comprises the following steps: an operator holds the handle 7 by hand, and the positioning pin I2, the positioning pin II 4, the screw hole pin I3, the screw hole pin II 5 and the via hole pin 6 are respectively checked corresponding to the positioning pin hole I8, the positioning pin hole II 10, the screw hole I9, the screw hole II 11 and the via hole 12 of the cylinder body shown in the attached drawing 3.
The inspection principle of the screw hole pin and the via hole pin is as follows: calculating the distance size tolerance from each screw hole I9, screw hole II 11, via hole 12 to positioning pin I8 and positioning pin II 10 of the cylinder body in the figure 3 through GB/T8069 and 1998, determining the size of each hole position of the detection tool substrate 1, assembling the positioning pin I2, the positioning pin II 4, the screw hole pin I3, the screw hole pin II 5 and the via hole pin 6 to the detection tool substrate 1, and detecting each hole of the cylinder body in the figure 3.
