Embodiment

For further understanding utility model content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

Consult accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7.

Embodiment 1

A kind of built-in push-down thread-hole part combined inspection tool comprises cannulated sleeve 1 and central shaft 2, and cannulated sleeve 1 and central shaft 2 are made by the high-hardness stainless steel material.Cannulated sleeve is a hollow cylinder, in central shaft is arranged, the cannulated sleeve both ends have two circular troughs of the depth of the cylindrical thread-hole part external diameter that detects two kinds of sizes, go side and not-go-end that two circular troughs of the identical size in two ends are respectively corresponding thread-hole part external diameters respectively.Central shaft is the screw thread core bar, there is the external thread of two kinds of sizes at both ends, central shaft is equipped with push-plate, cannulated sleeve has gathering sill 4, the gathering sill symmetry has two, the middle part has stationary point 7 and end that anchor point 6 is arranged, and push-plate 3 is a two halves formula structure, has tommy 5 that two halves formula push-plate is fixed on the central shaft 2.Manually push-plate drives central shaft to the middle part anchor point, realizes that the central shaft core bar is built-in, and manually push-plate drives central shaft to the end anchor point, realizes regulating the central shaft external thread and leans out cannulated sleeve, detects the diameter of screw size and screw thread effective length of thread-hole part.

The concrete assembling and the operation instruction of present embodiment:

Be built-in push-down thread-hole part combined inspection tool wiring layout as shown in Figure 1.Structure is formed: worker's type cannulated sleeve, and the central axle threads core bar, push-plate, worker's type cannulated sleeve has gathering sill.The two ends of worker's molded cannula shown in Figure 1 are respectively the go side and the not-go-end of primary connection terminal and inserts.Screw thread core bar one end is M10, and the other end is that M8 fits in worker's molded cannula.Push-plate is used for the double thread core bar and plays up-down adjustment, and plays spacing effect.The screw thread core bar is enclosed within worker's jacket tube, uses tommy again, tommy is done according to the fluting direction on the sleeve regulated and the location, so that control the use of screw thread core bar thread core lever lock tightening position.

The course of work: as shown in Figure 3 the screw thread core bar is adjusted to the gear place of M10, rotational lock is located left, and at this moment the screw thread core bar stretches out the screw rod of M10, is used for checking the size and the length of primary connection terminal M10 screw whether to meet examination requirements.As shown in Figure 5 the screw thread core bar is adjusted to the gear place of M8, rotational lock is located to the right, and at this moment the screw thread core bar stretches out the screw rod of M8, is used for checking the size of inserts M8 screw and length whether to meet examination requirements.As shown in Figure 6 a terminal is put into T-Φ 25 * M10 * 25, the logical not-go-end of Z-Φ 25 * M10 * terminal of 25 expression checks.T is the go side, and Z is a not-go-end, the go side is crossed and not-go-end to end the thread-hole part external diameter just qualified.The method of inspection of inserts external diameter is consistent with the method for inspection of a terminal as shown in Figure 7.

The effect of present embodiment is: solve former check primary connection terminal and inserts external diameter fit dimension and thread size and depth dimensional accuracy when incoming test, comprise that also some form and position tolerances such as right alignment can't accurately measure, so not only need to use more measurer, also influenced the time and the efficient of incoming test.By using cylinder rotating rod type combined inspection tool, this part volume is little, multiple functional, can not only check the size and the length of screw thread, can also check the logical not-go-end and the right alignment of terminal and inserts external diameter.Save a lot of loaded down with trivial details measuring means like this, also improved part by one-step incoming test qualification rate.

This tests using of tool and promotes and will directly and bring considerable economic as enterprise indirectly.
