Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
As depicted in figs. 1 and 2, test pin mechanism comprises: spacing adjuster bar 1, locating piece 4 and positive stop 8, spacing adjuster bar 1 for xsect be circular configuration, one spacing preiection 2 of moulding at an upper portion thereof, test pin 3 is arranged at the lower end of spacing adjuster bar 1, test pin 3 in figure detects the special-shaped test pin structure that detects hole for being used for, and can, with the employing Split type structure of spacing adjuster bar 1, also can be shaped in the end of spacing adjuster bar 1; Locating piece 4 is wherein to be fixedly connected with for same cubing base plate, on it, form circular pilot hole 6, preferably, at the interior guide 5 that arranges of pilot hole 6, guide 5 connects with pilot hole 6 interference fit, spacing adjuster bar 1 is placed in guide 5 and vertically arranges with the upper surface of locating piece 4, and spacing adjuster bar 1 moves axially along guide 5, and guide 5 is with the employing H7/h6 fit system of spacing adjuster bar 1.
In addition, the shape of preferred spacing adjuster bar 1 is the form that adopts one-body molded multidiameter, and its top is gag lever post 12, and its underpart is adjuster bar 13, and the diameter of axle of gag lever post 12 is greater than the diameter of axle of adjuster bar 13, and adjuster bar 13 is placed in pilot hole 6; The bottom of gag lever post 13 forms one section of D type chamfered edge 7, D type chamfered edge 7 extends axially to its variable cross section place along gag lever post 12, D type chamfered edge 7 extend axially the axial width that length is more than or equal to positive stop 8, by rotary stopper bar 12, make the semi circular surface of its lower end be placed in the upper surface of positive stop 8, or make its lower surface be placed in the upper surface of locating piece 4, thereby realize test pin 3 fast detecting or move back and pull out.In addition, positive stop 8 is equal with the depth dimensions in test pin 3 insertion detection holes along the gauge of spacing adjuster bar axial direction.
Preferably, test pin 3 is with the end of spacing adjuster bar 1 structure that is formed in one.
In this mechanism, the semi circular surface of gag lever post 12 lower ends is equivalent to the lower surface of spacing preiection 2, relies on this semi circular surface gag lever post 12 can be placed on the upper surface of positive stop 8, thereby makes it depart from the profiled holes of surveying, and makes it in off-position, as shown in Figure 2; By rotary stopper bar 12, D type chamfered edge 7 Rotate 180s ° by gag lever post 12, make positive stop 8 avoid the semi circular surface of gag lever post 12 lower ends simultaneously, thereby whole spacing adjuster bar 1 is moved down, test pin 3 inserts in institute's gaging hole, makes test pin 3 its in running order positions, as shown in Figure 1.
As shown in Figure 3 and Figure 4, in the lower end of adjuster bar 13, be provided with an adjusting handle ball 10, between the lower surface of handle ball 10 and locating piece 4, be provided with spring 11, spring 11 is placed on adjuster bar 13, test pin 3 is arranged at the upper end of gag lever post 12, when the lower surface of gag lever post 12 is placed in positive stop 8 upper surface, spring 11 is in compressive state.By rotary handle ball 10, make adjuster bar 13 rotate to the position of D type chamfered edge 7, dodge out the position-limiting action of positive stop 8, under the elastic force effect that is subject to spring 11, test pin 3 is withdrawn into off working state position automatically; Otherwise, while making test pin 3 in running order, driving handle ball 10, gag lever post 12 is shifted onto to the spacing position of positive stop 8, rotary handle ball 10, the upper surface that makes positive stop 8 contacts with the semi circular surface of gag lever post 12 lower ends, makes the position of gag lever post 12 fix under the effect of spring 11, now on test pin 3 positions, move, that has so just realized test pin 3 moves back the function of pulling out detection fast.Test pin shown in figure 3, also can be by changing test pin for detection of the profiled holes corresponding with it for detection of circular port.
Embodiment shown in Fig. 1 is as follows with difference embodiment illustrated in fig. 3:
Be inverted the position of test pin 3 and handle ball 10, and a position-limitting pin 9 is installed in the bottom of adjuster bar 13, as shown in Figure 1, and for the position of restraining spring 11.When carrying out testing, whole spacing adjuster bar 1 in Fig. 1 need to move down, the semi circular surface of gag lever post 12 lower ends need to be departed to the restriction of positive stop 8 like this, under the elastic force effect of spring 11, make its semi circular surface be placed in the upper surface of locating piece 4, and the embodiment shown in Fig. 3 is when carrying out testing, need to move on whole spacing adjuster bar 1, the duty of Fig. 1 and Fig. 3 is just in time contrary like this.
The invention described above embodiment sequence number, just to describing, does not represent the quality of embodiment.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
