Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
As depicted in figs. 1 and 2; Test pin mechanism comprises: spacing adjuster bar 1, locating piece 4 and positive stop 8 are circular configuration at spacing adjuster bar 1 for xsect, 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 among the figure detects the special-shaped test pin structure that detects the hole for being used for, and can divide body structure with the employing of spacing adjuster bar 1, also can be shaped in the end of spacing adjuster bar 1; Locating piece 4 wherein is to be used for being fixedly connected with the cubing base plate; Form circular pilot hole 6 on it, preferred, a guide 5 is set in pilot hole 6; Guide 5 connects with pilot hole 6 interference fit; Spacing adjuster bar 1 places in the guide 5 and vertically is provided 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 to adopt the form of one-body molded multidiameter, and its top is gag lever post 12, and its underpart is an 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 places in the pilot hole 6; The bottom of gag lever post 13 forms one section 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 of length more than or equal to positive stop 8; Make the semi circular surface of its lower end be placed in the upper surface of positive stop 8 through rotary stopper bar 12, 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 equates with the depth dimensions that test pin 3 inserts the detection hole 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 can gag lever post 12 be placed on the upper surface of positive stop 8, thereby makes it break away from the profiled holes of surveying, and makes it be in off-position, and is as shown in Figure 2; Simultaneously through rotary stopper bar 12,, make positive stop 8 avoid the semi circular surface of gag lever post 12 lower ends with D type chamfered edge 7 Rotate 180s on the gag lever post 12 °; 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, and is as shown in Figure 1.
Like Fig. 3 and shown in Figure 4; Be provided with an adjusting handle ball 10 in the lower end of adjuster bar 13; Be provided with spring 11 between the lower surface of handle ball 10 and locating piece 4, spring 11 is placed on the adjuster bar 13, and test pin 3 is arranged at the upper end of gag lever post 12; When the lower surface of gag lever post 12 was placed in positive stop 8 upper surfaces, spring 11 was in compressive state.Through 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 receives spring 11, test pin 3 is withdrawn into the off working state position automatically; Otherwise, when making test pin 3 in running order, driving handle ball 10; Gag lever post 12 is shifted onto 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, under the effect of spring 11, makes the stationkeeping of gag lever post 12; Move on test pin 3 positions this moment, and that has so just realized test pin 3 moves back the function of pulling out detection fast.Test pin shown in the figure 3 is used to detect circular port, also can be used to detect the profiled holes corresponding with it through changing test pin.
Embodiment shown in Figure 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, is used for the position of restraining spring 11.When carrying out testing; Whole spacing adjuster bar 1 among Fig. 1 need move down; The restriction that need the semi circular surface of gag lever post 12 lower ends be broken away from 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 embodiment shown in Figure 3 is when carrying out testing; Need to move on the whole spacing adjuster bar 1, the duty of Fig. 1 and Fig. 3 is just in time opposite like this.
The invention described above embodiment sequence number is not represented the quality of embodiment just to description.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
