Shown in composition graphs 1, Fig. 4 a and Fig. 4 b, the back-moving spring 14 that detecting module comprises bulb probing pin 20 and is set on bulb probing pin 20, bulb probing pin 20 is arranged in the upper chamber 161 of housing 10 along the longitudinally of housing 10.Particularly, bulb probing pin 20 comprises the detection bulb 21 and feeler 22 that set gradually from top to bottom.The first end 221 of feeler 22 is connected with detection bulb 21, and is disposed in the outside of housing 10 through centre bore 111 after connection together with detection bulb 21.Second end 222 of feeler 22 is disposed in the upper chamber 161 of housing 10, and the first end 221 of feeler 22 and the second end 222 are respectively the two ends of feeler 22.
In an example of the present invention, the shape of feeler 22 is set to cylindrical, and the shape of detection bulb 21 welds unthreaded hole (not shown) matching form with workpiece closes, the diameter simultaneously detecting the diameter of bulb 21 and the first end 221 of feeler 22 is all less than the diameter of workpiece welding unthreaded hole (not shown), by such design, when not being welded with workpiece at workpiece welding unthreaded hole place, the first end 221 of this detection bulb 21 and feeler 22 all can through workpiece welding unthreaded hole, and be pressed against to think that this place is welded with workpiece by mistake by workpiece welding unthreaded hole.Those skilled in the art can understand, detection bulb 21 can be set to spherical, also can be set to cuboid, cylinder etc., as long as when workpiece welding unthreaded hole place is welded with workpiece, being pressed against of workpiece can be subject to, and when not being welded with workpiece, can through workpiece welding unthreaded hole.Feeler 22 also can be designed to the shapes such as cuboid, cone or round platform, and those skilled in the art can select as required accordingly.
Shown in composition graphs 1, Fig. 4 a and 4b, feeler 22 is disposed with the first protuberance 223 and the second protuberance 224 from first end 221 towards the direction of the second end 222.And the first protuberance 223 and the second protuberance 224 extend along the direction of the longitudinally perpendicular to feeler 22 and cylindrical, the radial diameter of the second protuberance 224 is greater than the radial diameter of described first protuberance 223.Shown in composition graphs 1, Fig. 5 a and 5b, inner chamber between the upper end of the upper chamber 161 of the second protuberance 224 and housing 10 is provided with probing pin axle sleeve 23, and probing pin axle sleeve 23 is fixedly connected with the internal chamber wall of the upper chamber 161 of housing 10, such as probing pin axle sleeve 23 is connected by interference fit, buckle with between internal chamber wall or binding agent connection etc.In order to enable detecting module mobile along the longitudinally of housing 10 upper and lower (above-below direction as the Fig. 1 in the page) in the cavity of housing 10, matched in clearance between first protuberance 223 and probing pin axle sleeve 23, and matched in clearance between the internal chamber wall of the upper chamber 161 of the second protuberance 224 and housing 10.
As shown in Figure 1, in the upper chamber 161 between the second protuberance 224 and ring-shaped step 13, be provided with back-moving spring 14, and back-moving spring 14 is set on the feeler 22 below the second protuberance 224.When workpiece is pressed against detecting module, detection bulb 21 drives feeler 22 to move towards the lower cavity 162 of housing 10 in probing pin axle sleeve 23, make feeler 22 drive the first protuberance 223 and the second protuberance 224 along housing 10 longitudinally downwards (above-below direction as the Fig. 1 in the page) mobile, namely the second protuberance 224 moves towards ring-shaped step 13, and the second end 222 of feeler 22 moves in the lower cavity 162 of housing 10 through ring-shaped step 13 simultaneously.Because the second protuberance 224 is subject to the spacing of ring-shaped step 13, the longest stroke distances of the second protuberance 224 is made to be that the second protuberance 224 is in the distance of initial position between ring-shaped step 13, the impulse stroke scope of such detecting module can expand between 3 ~ 25mm, such as, the impulse stroke of detecting module can be set to 5mm, 10mm, 15mm, 17mm, 20mm, 22mm or 24mm etc.When the tests are completed, detecting module returns to initial position by means of the reaction force of the back-moving spring 14 be compressed on ring-shaped step 13.
In another example of the present invention, the diameter of the centre bore 111 on the lid 11 of housing 10 is greater than the diameter of detection bulb 21, make to detect bulb 21 when being subject to being pressed against of workpiece (not shown) by such design, along in the process of the longitudinally movement of housing 10, detection bulb 21 is pressed against in centre bore 111, now detects the longest distance of stroke for the movement of detection bulb 21 of bulb 21 movement.Certain those skilled in the art can understand, the diameter of centre bore 111 can also be less than the diameter of detection bulb 21, no matter the diameter of detection bulb 21 is greater than, is less than or equal to the diameter of detection bulb 21, detection bulb 21 is preferably made to be less than or equal to the second protuberance 224 in the distance of initial position between ring-shaped step 13 along the ultimate range of longitudinally (above-below direction as the Fig. 1 in the page) movement of housing 10 in the design.Certain those skilled in the art can be greater than the second protuberance 224 in the distance of initial position between ring-shaped step 13 by detecting the ultimate range of bulb 21 along longitudinally (above-below direction as the Fig. 1 in the page) movement of housing 10 as required.
Refer again to Fig. 1, Photoelectric Detection module 30 comprises the photoemission terminal 31 and opto-electronic receiver terminal 32 that are fitted to each other.Photoemission terminal 31 and opto-electronic receiver terminal 32 are separately positioned on the relative both sides of the lower cavity 162 of housing 10, and photoemission terminal 31 is all connected with control module with opto-electronic receiver terminal 32.When workpiece is pressed against the detection bulb 21 of detecting module, detecting module is mobile along the longitudinally downward (above-below direction as Fig. 1 in the page) of housing 10, to block the light wave transmissions between photoelectricity transmitting terminal 31 and opto-electronic receiver terminal 32, opto-electronic receiver terminal 32 trigger control module is sent and enters next step instruction operated.
As shown in Fig. 6 a to Fig. 6 c, in an example of the present invention, the lower end of housing 10 is provided with interface 15, and control module is programmable logic controller (PLC) (PLC), programmable logic controller (PLC) is connected with interface 15 powers to weld leak-proof device 100 to workpiece and and realizes the data that workpiece welds between leak-proof device 100 and external equipment and transmit.In another example of the present invention, workpiece welding leak-proof device 100 may be used for detection criterion part, such as projection welding part (in workpiece positive and negative), plant weldment, 3D blob of viscose etc.; Can also be used for detecting miniature parts, similar part (selecting moulding difference place); And independent detection or multiple positions combined detection of standard component or miniature parts can also be used for.In an also example of the present invention, workpiece welding leak-proof device 100 can be arranged on fixture, auxiliary mould or cubing, working position apparatus.When detecting soldering part, this device can be arranged on the fixed pedestal of fixture/auxiliary mould, the movable device that also can be arranged on fixture and/or auxiliary mould does to part to be detected and moves close to (being namely pressed against), unrestricted close to (being namely pressed against) direction, according to the difference of detected object, the impulse stroke of detecting module can be set in the scope of 3 ~ 25mm.
The concrete structure of workpiece welding leak-proof device 100 is further illustrated below by the operation principle describing workpiece welding leak-proof device 100 in detail.
When the assembly workpiece assembling of motor vehicles, such as move along the above-below direction of Fig. 1 in the page along certain direction, if part to be detected does not have solder skip, diameter due to part (such as project-welding nut) is less than the diameter of detection bulb 21, make to contact with bulb probing pin 20 and oppress (being namely pressed against) in motion process to detect bulb 21, bulb probing pin 20 is moved along the longitudinally of housing 10 towards Photoelectric Detection module 30 (namely towards the downward direction of Fig. 1 in the page).
When bulb probing pin 20 comes downwards to minimum point with workpiece, second end 222 of bulb probing pin 20 blocks the sub photoelectricity ripple sent of photoelectricity transmitting terminal, and then opto-electronic receiver terminal 32 cannot receive this photoelectricity ripple, opto-electronic receiver terminal 32 sends photoelectricity interrupt signal to PLC (programmable logic controller (PLC)) immediately, PLC (programmable logic controller (PLC)) is triggered and sends the action command (instruction such as such as fixture decline, clamping, soldering turret welding) carrying out next step, thus operator carries out the normal weld operation of postorder.According to being detected article structure difference, the impulse stroke of detecting module is between 3 ~ 25mm.After operation terminates, assembling finished piece(s) leaves, and bulb probing pin 20 is at the move under influence of back-moving spring 14 to initial position, and the photoelectricity ripple that photoemission terminal is launched is received terminal reception, and the leak-proof device 100 of workpiece welding afterwards enters next and detects circulation.
If a certain part of assembly workpiece solder skip, when workpiece is descending, the detection bulb 21 of bulb probing pin 20 is contactless or directly pass stamping holes (i.e. workpiece welding unthreaded hole), make bulb probing pin attonity, namely detecting module is owing to being in initial position and standby, therefore opto-electronic receiver terminal 32 continuous reception comes from the photoelectricity ripple of photoemission terminal 31, PLC (programmable logic controller (PLC)) is not triggered thus.Under the state that PLC (programmable logic controller (PLC)) is not triggered, PLC (programmable logic controller (PLC)) will not send the action command (instruction such as such as fixture decline, clamping, soldering turret action) entering next step, so just prevent the unexpected use of solder skip workpiece.Now operator will check workpiece, and withdraw fault part, and the leak-proof device 100 of workpiece welding afterwards enters next and detects circulation.
When using workpiece welding leak-proof device 100, workpiece can be welded leak-proof device 100 to be fixed on fixture fixed angles seat and to plant weldering bolt whether solder skip with what detect the workpiece (such as project-welding nut) that is positioned at inside workpiece stamping holes or be positioned at outside, workpiece can also be welded leak-proof device 100 and be contained in fixture lever arm adopts and detect finding whether solder skip close to mode.
