Weld jig inductor error prevention device
Technical field
The utility model belongs to the error prevention device being used in conjunction with weld jig.
Background technology
Common weld jig there will be due to neglected loading or because operator's error is not closed and just started to weld at fixture in welding process, and causes the percent defective of finished product to raise, thereby causes cost up.
Summary of the invention
The utility model provides a kind of weld jig inductor error prevention device, to solve common weld jig, there will be due to neglected loading or because operator's error is not closed with regard to the problem that starts to weld at fixture in welding process.
The technical scheme that the utility model is taked is: cylinder is arranged in frame, line slideway is fixedly connected with frame, stop is fixedly connected with frame, base plate and line slideway are slidably connected, base plate is fixedly connected with cylinder, air cylinder support one is fixedly connected with base plate, two guide pillar cylinders are fixedly connected with air cylinder support, sensor is fixedly connected with sensor fixation plate, contiguous block one is fixedly connected with sensor fixation plate, contiguous block one is fixedly connected with two guide pillar cylinders, cylinder support two is fixedly connected with frame, clamping cylinder is fixedly connected with cylinder support two, contiguous block two is fixedly connected with clamping cylinder, compact heap is fixedly connected with contiguous block two, stroke sensor is fixedly connected with clamping cylinder, in described sensor, there is LC oscillator, this oscillator is connected with switching stage, this switching stage is connected with amplification output stage.
The utility model has the advantages that novel structure, simply, can coordinate welding robot to use, be applicable to the welding of instrument board framework assembly series of products, prevent in advance because of operator's error or neglected loading causes percent defective, thereby improve the quality of products and technological level, improve product percent of pass, reduce costs.

The specific embodiment
Cylinder 9 is arranged in frame 15, line slideway 7 is fixedly connected with frame, stop 8 is fixedly connected with frame, base plate 6 is slidably connected with line slideway 7, base plate 6 is fixedly connected with cylinder 9, air cylinder support 1 is fixedly connected with base plate 6, two guide pillar cylinders 5 are fixedly connected with air cylinder support 4, sensor 1 is fixedly connected with sensor fixation plate 2, contiguous block 1 is fixedly connected with sensor fixation plate, contiguous block 1 is fixedly connected with two guide pillar cylinders 5, cylinder support 2 11 is fixedly connected with frame 15, clamping cylinder 12 is fixedly connected with cylinder support two, contiguous block 2 14 is fixedly connected with clamping cylinder 12, compact heap 13 is fixedly connected with contiguous block 2 14, stroke sensor 10 is fixedly connected with clamping cylinder 12, in described sensor 1, there is LC oscillator 101, this LC oscillator is connected with switching stage 102, this switching stage is connected with amplification output stage 103.
Operation principle, clamping cylinder 12 drives compact heap 13 that metal works 16 is clamped, stroke sensor 10 is used for gathering clamping cylinder stroke, cylinder 9 drives base plate 6 horizontal slips, two guide pillar cylinders drive sensor fixation plate to move up and down, make sensor 1 approach metal works 16, when sensor 1 reaches distance of reaction, LC oscillator produces an alternating magnetic field, in metal works, produce eddy current, thereby generation oscillatory extinction, so that failure of oscillation, switching signal is processed and converted to the variation of oscillator vibration and failure of oscillation by rear class amplifying circuit, trigger and amplify output stage, send signal to host computer, when host computer is received after signal, turntable can rotate, after turntable is rotated in place, robot just can weld, if operating personnel's piece installing is not in place or single-piece size has deviation, sensor 1 surveys not in place or while surveying less than workpiece, no signal is sent, and turntable can not rotate, and robot does not receive turntable and is rotated in place signal and just can not welds.
