Specific implementation mode
Structure, ratio, size depicted in Figure of description etc., only to coordinate the revealed content of specification, with
Understand for those skilled in the art and read, is not limited to the enforceable qualifications of the utility model, therefore does not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the utility model institute
Under the effect of capable of generating and the purpose that can reach, the model that can cover in the revealed technology contents of the utility model should all be fallen
In enclosing.Meanwhile cited such as "upper", "lower", "front", "rear", " centre " term in this specification, it is merely convenient to describe
Be illustrated, rather than to limit the enforceable range of the utility model, relativeness is altered or modified, without substantive change
Under technology contents, when being also considered as the enforceable scope of the utility model.
In conjunction with Fig. 1-Fig. 3, the utility model is a kind of snap spring of transmission shaft neglected loading error-proof detection device, including holder 1, holder
1 is equipped with pressure head 2 moving up and down, and the pressure head 2 includes inner sleeve 21 and outer cover 22, and detection device includes locating rack 3 and position
Ruler 4 to be moved, vertical through-hole is provided on locating rack 3, floating axle 31 is equipped in through-hole, 31 lower end of floating axle is equipped with link block 32,
The link block 32 is connected with the movable head 41 of displacement ruler 4, and the locating rack 3 and displacement ruler 4 are installed on holder 1, institute
The outer cover 22 for stating link block 32 and pressure head 2 is engaged and synchronization action, and when outer cover 22 moves up and down, floating axle 31 is in through-hole
In slide up and down.Pressure head 2 as needed can be replaced, the link block 32 with outer cover 22 only with being engaged, that is, combine Fig. 1 with
Fig. 2, the outer cover 22 are resisted against the lower section of link block 32, link block 32 while being moved up, outer cover when outer cover 22 moves up
22 when moving down, and link block 32 is moved down automatically by gravity；The quick-replaceable for having reached pressure head 2 through this structure uses
Purpose.
With reference to figure 1- Fig. 3, the present apparatus can solve two technical problems, and whether one be arranged on detection seeker 100
There is clamp spring 200, the other is whether detection clamp spring 200 is installed in place.Specifically working process and principle are：
One, detect on seeker 100 and whether be arranged with clamp spring 200, with reference to figure 1, transmission shaft 300 by fixture vertically into
Row positioning, seeker 100 is placed on the upper end of transmission shaft 300, if being cased with clamp spring 200 on seeker 100, starts in work
Afterwards, holder 1 moves downwardly together with pressure head 2, locating rack 3 and displacement ruler 4, and inner sleeve 21 acts against clamp spring 200 and pushes it into biography
Moving axis 300, and outer cover 22 can be blocked, i.e., inner sleeve 21 continues to move down and outer cover 22 is motionless, and displacement ruler 4 is also continued to moving down
It is dynamic, and then relative displacement ruler 4 moves up floating axle 31, the movable head 41 of displacement ruler 4, which elongates, generates electric signal, and electric signal passes to
Explanatory note or prompt tone are generated in controller.
If neglected loading clamp spring 200 on seeker 100, holder 1 with pressure head 2, locating rack 3 and displacement ruler 4 together to
When lower mobile, inner sleeve 21 and outer cover 22 move synchronously, and do not relatively move, and not will produce electric signal, and controller will produce correlation
Explanatory note or prompt tone, staff handles in time.
Two, whether detection clamp spring 200 is installed in place, when being cased with clamp spring 200 on seeker 100, with pushing away for inner sleeve 21
Action is used, and clamp spring 200 is pulled in the card slot of transmission shaft 300, if position accurately if clamp spring 200 spring back, outer diameter reduces, and is
Outer cover 22, which moves down, concedes space, drives link block 32 to move downwardly together when outer cover 22 moves down, the activity of displacement ruler 4
First 41 shorten generation electric signal, and electric signal passes to controller and generates explanatory note or prompt tone.
If clamp spring 200 is not installed in place, outer diameter is constant, and outer cover 22 cannot move down, and not will produce electricity
Signal, controller will produce relevant explanatory note or prompt tone, and staff is handled in time.
In a preferred embodiment, as shown in figures 1 and 3, it is equipped between the link block 32 and locating rack 1 and is set in floating
Spring 33 on axis 31, in order to which outer cover 22 resets.
In a preferred embodiment, as shown in figure 3, in order to installation convenience, while avoid floating axle 31 from locating rack 3 take off
Go out, the upper end of the floating axle 31 is equipped with limited block 34.Further, 3 upper end of the locating rack is set there are two baffle 35, described
Limited block 34 is located between two baffles 35, and is only capable of moving in above-below direction, cannot rotate.
