Embodiment
Below in conjunction with accompanying drawing to the utility model provided a kind of device that is used to detect the screw relative height further explain.
Wherein, said screw relative height is the height of screw with respect to car light 11 lamp bodies.
The concrete connected mode of said a kind of device that is used to detect the screw relative height is following:
Be connected with cylinder 2 on the support 1; Said cylinder 2 lower ends are connected with web joint 4, and said web joint 4 ends are fixedly connected with bearing 3, and said bearing 3 is socketed on the axis of guide 5 upper ends; The said axis of guide 5 lower ends are connected with sensor stand 8 upper surfaces; The said axis of guide 5 surfaces are provided with elastomeric element 6, and said elastomeric element 6 upper ends contact with bearing 3 lower surfaces, and the length of said elastomeric element 6 is the distance between bearing 3 lower surfaces to sensor stand 8 upper surfaces; Said sensor stand 8 lower surfaces are connected with sensor 9; Said sensor 9 lower surfaces and screw 10 upper surface joints are provided with baseline rod 7 between the body of vehicle light surface 12 of said sensor stand 8 and car light 11, fix through nut 14 between said sensor stand 8 and the baseline rod 7; Said baseline rod 7 lower surfaces contact with body of vehicle light surface 12, and said car light 11 is fixed on the car light jig 13.
Wherein, Said elastomeric element 6 is preferably spring, said elastomeric element act as the driving force of transmitting between bearing 3 and the sensor stand 8, make maintenance one fixed range between bearing 3 and the sensor stand 8; And when device receives big external force, play buffering, protect.Said nut 14 plays the role of positioning, and promptly controls the position of sensor stand 8 on baseline rod 7.
Wherein, The principle of work of sensor 9 is: when (not duty), the value on its display panel is 0 to sensor 9 in the raw, when sensor stand 8 drives sensors 9 and moves downward; Sensor 9 produces contraction with the contact site of screw 10 upper surfaces because of being squeezed; At this moment, the value shown in the display panel of sensor 9 is the distance that sensor 9 is shunk.
Said a kind of Device Testing mode that is used to detect the screw relative height is following:
At first, confirm detection reference through baseline rod 7:
This standard is exactly the length that baseline rod 7 stretches out with respect to sensor stand 8; It is the distance on sensor stand 8 and body of vehicle light surface 12; The value (being assumed to be S) that this moment, sensor 9 display panels showed; Promptly confirm as specification product (qualified screw 10 is with respect to car light 11 lamp body surface height), this numerical value S is detection reference.
Confirm a tolerance value then; Be the tolerance interval value of screw 10 relative heights, promptly when the device that provides with the utility model detects the relative height of screw 10, if measured value drops in the scope of S-tolerance value～S+ tolerance value; Then this moment, screw 10 promptly met the requirements; Otherwise if the relative height of screw to be detected 10 is low, the value that display panel showed of sensor 9 can be lower than the S-tolerance value so; If the relative height of screw 10 is high, the value that display panel showed of sensor 9 will be higher than the S+ tolerance value so.
The detection step is following:
Through the motion of cylinder 2, drive web joint 4 motions, the motion of web joint 4 drives bearing 3 motions; The motion extrusion spring 6 of said bearing 3 moves; And then drive sensor stand 8 movement therewith, and then promote to be connected sensor 9 and baseline rod 7 on the sensor stand 8, at this moment; Sensor 9 shows numerical value with the contact segment of screw 10 because of being squeezed on display panel, thereby detects the relative height of screw 10 with respect to body of vehicle light surperficial 12.
In a kind of Device Testing mode that is used for detecting the screw relative height that the utility model provided, cylinder 2 only plays a role in promoting, and the reference field of detection is car light 11 self face, and promptly the body of vehicle light surface 12.What be associated with detection has only baseline rod 7, sensor stand 8 and sensor 9, and this three is relatively for being rigidly connected.Therefore, when sensor stand 8 is directed to after the spring 6 of axle on 5 promote, no matter how many lamp body deflections of car light 11 is, the value that sensor 9 is detected is the height of screw 10 with respect to car light 11 lamp bodies.
Use a kind of device that is used to detect the screw relative height that the utility model provided; In testing process; Needn't consider what of body of vehicle light deflection; Make the sensor value be the height of screw, thereby improve the efficient of equipment process with respect to body of vehicle light, and the apparatus structure advantages of simple.
