Abstract

The invention 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

A kind of indirect induction installation detecting for nut
Technical field
The present invention relates to a kind of device detecting for nut, especially relate to a kind of indirect induction installation detecting for nut.
Background technology
Along with the fast development of domestic car industry, nut weld technique adopts in a large number.On a body in white, be generally welded with 60-80 nut, for fixing 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 for the detection of workpiece, extensively use is closely to connect inductor directly to respond to.Proximity sense detects by induction area and coverage.In nut pattern welding equipment, while having multiple nut model, can not effectively detect the size of nut simultaneously.And the accuracy that the existence of welding slag and dust impact detects.
Summary of the invention
Object of the present invention is exactly to provide a kind of usable range wide, the safe and reliable indirect induction installation detecting for nut in order to overcome the defect of above-mentioned prior art existence.
Object of the present invention can be achieved through the following technical solutions:
A kind of indirect induction installation detecting for nut, 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 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 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.
In described holder, be provided with register pin, this register pin is for locating the position that closely connects inductor.
In described holder, be provided with spring stationary shaft, the lower end of described spring is set on spring stationary shaft.
The size of described test pin is corresponding with the size of 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 encountered nut and depressed by nut, test pin drives kinematic axis and coupling shaft to move downward, and 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 there is no nut, test pin is not affected by external force, and now coupling shaft is subject to the support of spring and away from the breach of the axis of guide, therefore, closely connects inductor induction less than the existence of coupling shaft, does not send signal, draws the non-existent conclusion of nut.
Compared with prior art, the present invention has the following advantages:
One, the present invention is simple in structure, is easy to manufacture;
Two, usable range is wide; By changing test pin, can detect the nut of different sizes;
Three, safe and reliable: in soldering cramping apparatus, can effectively to avoid the interference of welding slag and dust;
Four, can design by modularity: except test pin, remaining part all can large-scale production.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention;
Fig. 2 is plan structure schematic diagram of the present invention.
In figure, 1 is test pin, and 2 is coupling shaft, and 3 is kinematic axis, and 4 is the axis of guide, and 5 is register pin, and 6 is spring, and 7 is holder, and 8 is spring stationary shaft, and 9 for closely connecing inductor.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
A kind of indirect induction installation detecting for nut, as Fig. 1, shown in Fig. 2, this device comprises holder 7, the axis of guide 4, closely connect inductor 9, kinematic axis 3, test pin 1, coupling shaft 2 and spring 6, the lower end of the axis of guide 4 is positioned at holder 7, the axis of guide 4 is positioned at a side of holder 7 and offers breach, closely connecing inductor 9 is located in holder 7, the induction zone that closely connects inductor 9 is positioned at the indentation, there of the axis of guide 4, kinematic axis 3 is set in the outside of the axis of guide 4 upper ends, test pin 1 is located at the upper end of kinematic axis 3, coupling shaft 2 is set in the axis of guide 4, the upper end of coupling shaft 2 and test pin 1 butt.In holder 7, be provided with register pin 5, this register pin 5 is for locating the position that closely connects inductor 9.In holder 7, be provided with spring stationary shaft 8, the lower end of coupling shaft 2 is hollow structure, and the upper end of spring 6 is connected in this hollow structure, and the lower end of spring 6 is located on spring stationary shaft 8.The size of test pin 1 is corresponding with the size of nut to be measured, and test pin 1 is made by metal material, and through heat treated.Test pin 1 is replaceable.
When test pin 1 is encountered nut and depressed by nut, test pin 1 drives kinematic axis 3 and coupling shaft 2 to move downward, coupling shaft 2 extrusion springs 6 also move downward, when coupling shaft 2 moves to the indentation, there of the axis of guide 4, closely connect inductor 9 and sense the existence of coupling shaft 2 and send signal, confirm that nut exists.When there is no nut, test pin 1 is not affected by external force, and now coupling shaft 2 is subject to the support of spring 6 and away from the breach of the axis of guide 4, therefore, closely connects inductor 9 inductions less than the existence of coupling shaft 2, does not send signal, draws the non-existent conclusion of nut.
