For the ease of describe this utility model and simplify description, rather than indicate or imply indication device or element must have it is specific
Orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.Additionally, term " the
One ", " second ", " the 3rd " are only used for describing purpose, and it is not intended that indicating or implying relative importance.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected, or be detachably connected, or integratedly
Connection；Can be mechanically connected, or electrically connect；Can be joined directly together, it is also possible to be indirectly connected to by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Concrete meaning of the language in this utility model.
With reference to Fig. 1, a kind of embodiment of this utility model.The present embodiment can be used on detection workpiece being provided with circular hole, and
Nut, unified specification workpiece of the circular hole aperture more than nut internal diameter are welded with circular hole.In the present embodiment, a kind of robot welding
The anti-nut of fixture omits alarm device, for workpiece of the detection with nut, including for putting the workpiece for being welded with nut 12
Fixture 1, be provided with installing hole 11 on the fixture, sensing pin 2 is provided with by spring 21 in the installing hole, the sensing is sold
Top end diameter is more than the nut internal diameter, and the installing hole bottom is provided with inductive proximity switches 3, and the inductive proximity switches connect
Central processing unit 4 is connected to, the central processing unit is connected with alarm 5, and inductive switch 6, the sense are additionally provided with the fixture
Inductive switch is processed with the central authorities and is connected.In the technical program, all streamlines unified specification workpiece to be welded is through fixture.
With reference to Fig. 2, after workpiece is put on fixture, workpiece signal is sent to central authorities by inductive switch on having sensed that workpiece is placed
Processor, simultaneously because the workpiece is unqualified workpiece, without bolt on workpiece, sensing pin is without action.Inductive proximity switches
Signal cannot be sensed, central processing unit does not receive inductive proximity switches signal, and then judges that workpiece is unqualified, by signal
It is sent to alarm to be reported to the police, points out workman's workpiece unqualified.With reference to Fig. 3, when workpiece is qualified workpiece, inductive switch is received
To induced signal, with reference to Fig. 4 nuts 9 pin pressure will be sensed, inductive proximity switches sense the signal of sensing pin, signal is sent
To central processing unit, central processing unit had both received inductive switch signal, also received inductive proximity switches signal, judged that the workpiece is
Qualified workpiece, alarm does not work, and workpiece continues traveling downwardly the welding process of robot.
This utility model inductive proximity switches can be 2D0 (distance of reaction 1mm) inductive proximity switches, and spring is avoided as far as possible
Interference.
With reference to Fig. 5, this utility model installs inductive switch and inductive proximity switches additional on the fixture of assembly line work, while
Using ripe PLC technology, simple structure low cost timely and effectively detects workpiece, improves later stage welding qualified
Rate, has liberated manpower, improve production efficiency.
The sensing pin is internal to be provided with connecting hole 21, and the spring is connected in connecting hole.In the technical program, in spring
Put pattern, it is ensured that sensing pin periphery is near enough with inductive proximity switches, while it also avoid spring and rocking in installing hole, bending
Cause erroneous judgement situation.
The inductive proximity switches are also associated with sensing lamp.In the technical program, inductive proximity switches connection sensing lamp, when
After sensing signal, central processing unit is sent a signal to, while sensing, lamp is bright, double insurance prevents qualified workpiece misjudged,
Whether break down with the judgment means of reporting situations of sensing lamp also dependent on central processing unit simultaneously.
The fixture is provided with the Magnet 8 for the workpiece to be sucked.In the technical program, prevent some lighter
Sensing pin pressure can not be increased workpiece captivation by the nut of workpiece, improve the sensitivity of reaction.
The installing hole includes the nut bore 12 of upper end and the spring eye 13 of bottom, and spring eye is exposed on the sensing pin top
Upper end and less than nut bore top.In the technical program, in order to increase this new detection range, it is ensured that as long as there is prominent spiral shell
Female welding portion can detect, and installing hole is fabricated to nut bore.With reference to Fig. 5 sensing pins in nut bore, workpiece does not have
Nut, central processing unit receives inductive switch signal, does not have inductive proximity switches signal, is reported to the police.It is qualified with reference to Fig. 6
Workpiece nut is entered in nut groove, and by sensing pin pressure, inductive proximity switches send signal, and central processing unit is not reported to the police, workpiece
It is qualified to enter next operation.
This utility model detects before workpiece welding to workpiece, improves solder yield, while simple structure, raising
Welding efficiency and qualification rate, reduce labour cost and human cost.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Personnel's some that to be made to some of which part variations embody principle of the present utility model, belong to this utility model
