It states above bottom plate, and by the spring and the bottom plate elastic connection, several locating pieces are fixed on the jig plate,
And one is formed on the jig plate for placing the localization region of plaque.
Further, being installed with linear bearing at four angles of the jig plate, insertion institute is installed in the bottom plate
State the guide post in linear bearing.
Further, supporting block is arranged in the top of the bottom plate, the jig plate falls within the supporting block after being pressed down
On.
The beneficial effects of the utility model are: 1. the utility model are adornd by the common end of PLC wiring board and on-off judgement
Board position whether neglected loading screw, simple and effective, as long as two gold-plated testing needles are contacted with screw, PLC controller can be done immediately
Judge out, it is fast not only to detect speed, but also erroneous detection and missing inspection can be prevented；2. utility model is gone by the jig of setting elasticity
The vibration generated when gold-plated testing needle is contacted with screw is absorbed, can prevent gold-plated testing needle from deforming or being broken, ensure that detection
Effective progress of work；3. the utility model goes to the neglected loading position for expressing plaque by setting touch screen or indicator light, so as to
Neglected loading position is rapidly found out in operator, it is simple and convenient.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.
Fig. 1 is the structure chart of plaque embedded screw neglected loading detection device disclosed in embodiment one；

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Embodiment one
Plaque embedded screw neglected loading detection device shown in Figure 1, comprising: jig 10, several detection mould groups 20, cylinder
30, PLC controller and alarm bell, jig 10 are used for the clamping position of plaque, and several detection mould groups 20 are set to the top of jig 10,
Cylinder 30 drives all detection mould groups 20 to rise or decline.Referring to fig. 2, detection mould group 20 is by bakelite 21 and two gold-plated tests
Needle 22 forms, and two gold-plated testing needles 22 are fixed in bakelite 21；A common end is provided on the wiring board of PLC controller,
And quantity input terminal corresponding with screw number, a gold-plated testing needle detected in mould group pass through conducting wire and common end
Connection, another gold-plated testing needle are connected by conducting wire with corresponding input terminal.
Cylinder 30 declines as power source drive detection mould group 20, and two gold-plated testing needles 22 are pressed on the screw of plaque,
