The length of card mark 42 is the lower limit value that 1 length of part allows；Inside caliper mark include under internal diameter difference card mark 51 and be printed in testing stand 3
On internal diameter on difference control figure 52, the diameter of difference card mark 51 is the lower limit value of 1 internal diameter of part, poor comparative diagram on internal diameter under internal diameter
The diameter of shape 52 is the upper limit value of 1 internal diameter of part, and difference card mark 51 is compareed in the projection B on testing stand 3 with difference on internal diameter under internal diameter
52 eccentric setting of figure, and 51 projection B on testing stand 3 of difference card mark under the top of difference control figure 52 and internal diameter on internal diameter
Intersection；The front of difference card mark 51 is equipped with upright support frame 6 under internal diameter, and support frame 6 is equipped with first light source component 53 and first
Light source switch 54, first light source switch 54 connect first light source component 53, and the light-emitting surface of first light source component 53 faces internal diameter
Lower difference card mark 51.
Preferably, as shown in Figure 2 and Figure 5, testing stand 3 is equipped with dark bottom plate 31, and difference control figure 52 is on internal diameter
White, and being printed on bottom plate 31 makes part 1 in the projection A on testing stand 3, difference control figure 52 and bottom plate on internal diameter
There is more striking contrast, to enable detection work more easily laborsaving between 51.
Preferably, as depicted in figs. 1 and 2, first light source component 53 includes that the first pcb board 531 of annular and several weld
The first LED532 being connected on the first pcb board 531, the internal diameter of the first pcb board 531 are more than or equal to difference card mark 51 under internal diameter
Diameter, so that the light for emitting the first LED532 faces difference card mark 51 under internal diameter, convenient for observation part 1 in testing stand
Projection on 3.
Preferably, as shown in Figures 2 to 4, length card mark include along the radial card parameter 43 set gradually from the inside to the outside,
Second light source component 44 and light-transmission tube 45, second light source component 44 include that the second pcb board 441 and several are welded in the 2nd PCB
The light-emitting surface of the 2nd LED442 on plate 441, the 2nd LED442 are towards light-transmission tube 45.The light of 2nd LED442 transmitting passes through saturating
Light pipe 45, so that length card mark be made to shine.
Preferably, second light source component 44 and light-transmission tube 45 are all set in length card and put on one end far from testing stand 3, by
Only need to observe the light conditions that length card puts on one end far from testing stand 3, therefore, the second light when detecting the length of part
