Abstract
The utility model relates to an indirect sensor for nut detection. The sensor comprises a fixing base, a guiding shaft, a proximity sensor, a moving shaft, a detection pin, a connection shaft, and a spring. The bottom end of the guiding shaft is located inside the fixing base, and a notch is provided in one side of the guiding shaft inside the fixing base. The proximity sensor is arranged in the fixing base, and a sensing area of the proximity sensor is positioned in the notch of the guiding shaft. The top end of the guiding shaft is sleeved inside the moving shaft, in the top end of which the detection pin is arranged. The connection shaft is sleeved in the guiding shaft, and the top end of the connection shaft butts against the detection pin. The spring is clamped between the connection shaft and the fixing base. When the detection pin touches a nut and is pressed down by the nut, the detection pin drives the moving shaft and the connection shaft to move downwards; and when the connection shaft reaches the position of the notch, the proximity sensor senses the connection shaft and transmits a signal to confirm that the nut exists. Compared with the prior art, the sensor has such advantages as a wide range of uses, safety, and reliability.
Description
Technical field
The utility model relates to a kind of device for the nut detection, especially relates to a kind of indirect induction installation for the nut detection.
Background technology
Along with the fast development of domestic car industry, nut weld technique adopts in a large number.Generally be welded with 60-80 nut on the body in white, be used for the fixedly parts such as inside gadget and instrument panel.For the normal use of next procedure, need to confirm the having or not of nut, size.At present, in soldering cramping apparatus design, what extensively use for the detection of workpiece is closely to connect inductor directly to respond to.Proximity sense detects by induction area and coverage.In the nut pattern welding equipment, when multiple nut model is arranged simultaneously, can not effectively detect the size of nut.And the accuracy that the existence of welding slag and dust impact detects.
The utility model content
The purpose of this utility model is exactly to provide a kind of usable range wide, the safe and reliable indirect induction installation that is used for the nut detection for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of indirect induction installation for the nut detection, this device comprises holder, the axis of guide, closely connect inductor, kinematic axis, test pin, coupling shaft and spring, the lower end of the described axis of guide is positioned at holder, the axis of guide is positioned at a side of holder and offers breach, the described inductor that closely connects is located in the holder, the induction zone that closely connects inductor is positioned at the indentation, there of the axis of guide, described kinematic axis is set in the outside of axis of guide upper end, described test pin is located at the upper end of kinematic axis, described connecting bushing is located in the axis of guide, the upper end of coupling shaft and test pin butt, described Spring Card is located between coupling shaft and the holder.
The lower end of described coupling shaft is hollow structure, and the upper end of described spring is connected in this hollow structure, the lower end of spring and holder butt.
Be provided with the register pin that closely connects sensor location for the location in the described holder.
Be provided with the spring stationary shaft in the described holder, the lower end of described spring is set on the spring stationary shaft.
The size of described test pin is big or small corresponding with nut to be measured, and described test pin is replaceable.
Described test pin is made by metal material, and through heat treated.
When test pin is run into nut and is depressed by nut, test pin drives kinematic axis and coupling shaft moves downward, and the coupling shaft extrusion spring also moves downward, when coupling shaft moves to the indentation, there of the axis of guide, closely connect inductor and sense the existence of coupling shaft and send signal, confirm that nut exists.When not having nut to exist, test pin is not affected by external force, and coupling shaft was subject to the support of spring and away from the breach of the axis of guide, therefore, closely connect the inductor induction less than the existence of coupling shaft this moment, did not send signal, drew the non-existent conclusion of nut.
Compared with prior art, the utlity model has following advantage:
One, the utility model is simple in structure, is easy to make;
Two, usable range is wide: by changing test pin, can detect the nut of different sizes;
Three, safe and reliable: as in soldering cramping apparatus, can effectively to avoid the interference of welding slag and dust;
But four modularities design: except test pin, but all large-scale production of remaining part.
