Abstract
The invention provides a nut detection fixture structure comprising a positioning bakelite, a threaded rod, a metal inductive switch and a lower positioning screw, wherein the metal inductive switch is fixedly arranged at the top end of the threaded rod; and the threaded rod penetrates through the positioning Bakelite so that threaded rod can move up and down. The nut detection fixture structure further comprises: a fixation baffle plate, which is fixedly arranged at the upper end of the threaded rod, and an elastic structure penetrating through the threaded rod, wherein the upper end of the elastic structure is connected to the fixation baffle plate while the lower end thereof is connected to the positioning bakelite. Compared with the prior art, the nut detection fixture structure is capable of accurately detecting a nut when the distance between the metal inductive switch and the nut is overlarge by changing a fixed height detection manner of the threaded rod into an self-adaptive height detection manner of the elastic structure of the screwed rod; therefore, the accuracy of the detection result is improved.
Description
[technical field]
The present invention relates to a kind of nut detecting tool, particularly a kind of hot-melting nut detects jig structure.
[background technology]
In electronic product assembling processing procedure, usually need first hot-melting nut on the part of electronic product, and then each parts and components of product is screwed assembles.Before the hot-melting nut, to manually be placed in nut on the plastic parts first, and then by hot melting fixture with nut heating and be pressure bonded on the plastic parts.On the one hand, because the work major part of putting nut and hot-melting nut is by manually finishing, and the nut quantity on machine is more, and the people pendulum can occur unavoidably leaking or leak the molten operation carelessness that waits when operation, cause the top nut of product plastic parts to lack.Therefore, after hot-melting nut is finished, need to detect the nut on the product plastic parts by detecting tool, guaranteeing does not have nut loss.
See also Fig. 1, it illustrates a kind of nut detecting tool structure of prior art, and it comprises location bakelite 30, one screw rods 40 and a metal inductive switch 41.This metal inductive switch 41 is fixedly arranged on the top of this screw rod 40, in order to detect nut 20.This screw rod 40 wears by upper set screw 42 and lower set screw 43 and is fixed on this location bakelite 30, it can adjust height with respect to these location bakelite 30 projections by regulating upper set screw 42 and lower set screw 43, thereby debugs the detection height of this metal inductive switch 41.
During detection, operating personnel are positioned over plastic parts 10 on this nut detecting tool, make this metal inductive switch 41 corresponding to nut 20 positions on this plastic parts 10, and press plastic parts 10 downwards, when nut 20 and this metal inductive switch 41 approach within the distance of reaction, this metal inductive switch 41 is sensed this nut 20, the inductive switch action, and the sensor circuit response concurrent of this nut detecting tool goes out cue; When nut 20 disappearance, this metal inductive switch 41 is failure to actuate because sensing nut 20, and this moment, the sensor circuit of nut detecting tool did not have response not send cue.
But the nut detecting tool of prior art is when detecting, and when following situation occurring, the distance of metal inductive switch and nut is excessive, when surpassing this distance of reaction, and metal inductive switch induction inefficacy, shine into testing result inaccurate:
(1) the plastic parts distortion causes nut and metal inductive switch apart from excessive;
(2) detection of metal inductive switch is highly debugged to such an extent that too low nut and the metal inductive switch distance that causes is excessive;
(3) screw nut hot melting on the lower side depth stop be absorbed in and cause nut and metal inductive switch distance excessive in the plastic parts.
Therefore, be necessary to develop a kind of nut detecting tool structure in fact, overcome the defective of prior art, make when distance is larger between metal inductive switch and the nut and also can accurately detect nut, improve the accuracy rate of testing result.
[summary of the invention]
In view of this, the object of the present invention is to provide a kind of nut detecting tool structure, overcome the defective of prior art, make when distance is larger between metal inductive switch and the nut and also can accurately detect nut, improve the accuracy rate of testing result.
For achieving the above object, the invention provides a kind of nut detecting tool structure, comprise that a location bakelite, a screw rod, a metal inductive switch reach set screw, this metal inductive switch is fixedly arranged on the top of this screw rod, it is characterized in that, this screw rod is arranged on this location bakelite up and downly, and this nut tool detection architecture also comprises:
One fixed dam, it is fixedly arranged on the upper end of this screw rod;
One elastic construction, it is arranged on this screw rod, and its upper end connects this fixed dam, and its lower end is connected in this location bakelite.
Preferably, nut detecting tool structure of the present invention also comprises a buffering spacer, its be movably set on this screw rod and be padded on this elastic construction lower end and this location bakelite between.This buffering spacer prevents that in order to cushion the elastic force of this elastic construction the elastic force of this elastic construction from directly acting on this location bakelite its injury.
Preferably, this elastic construction is a spring.Elastic reaction by this spring, the height of the metal inductive switch of this screw tip can rely on operating personnel to pressing of plastic parts and adaptively buffering adjustment downwards, thereby make the distance between the nut in this metal inductive switch and the plastic parts approach to this distance of reaction, guarantee that this metal inductive switch detects nut, improve the accuracy rate of testing result.
Compared to prior art, nut detecting tool structure of the present invention is by changing screw rod level altitude detection mode into the self-adaptation height detection mode of screw rod elastic construction, when making the distance of metal inductive switch and nut excessive, can accurately detect nut, improve the accuracy rate of testing result.

Fig. 2 is the diagrammatic cross-section of nut detecting tool structure of the present invention preferred embodiment.
[embodiment]
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
See also Fig. 2, it illustrates the diagrammatic cross-section of nut detecting tool structure of the present invention preferred embodiment.The invention provides a kind of nut detecting tool structure, comprise that a location bakelite 50, a screw rod 60, a metal inductive switch 61 reach set screw 65, this metal inductive switch 61 is fixedly arranged on the top of this screw rod 60, it is characterized in that, this screw rod 60 is arranged on this location bakelite 50 up and downly, and this nut detecting tool structure also comprises a fixed dam 62, a spring 63 and a buffering spacer 64.
This fixed dam 62 is fixedly arranged on the upper end of this screw rod 60.This spring 63 is arranged on this screw rod 60, and its upper end connects this fixed dam 62, and its lower end is connected in this location bakelite 50 by this buffering spacer 64.This buffering spacer 64 is movably set on this screw rod 60 and is padded between these spring 63 lower ends and this location bakelite 50.This buffering spacer 64 prevents that in order to cushion the elastic force of this spring 63 elastic force of this spring 63 from directly acting on this location bakelite 50 its injury.
