Abstract
The utility model provides a novel leakproof mechanism for a built-in weld nut, which comprises a proximity sensor; one end of a sleeve is connected with an end cap; the proximity sensor penetrates through and is connected with the end cap; one end of a detection pin is arranged in the sleeve; the other end of the detection pin penetrates through the sleeve; a wear-resisting bushing is arranged between the sleeve and the detection pin; one end of a spring is sleeved on the detection pin; and the other end of the spring abuts against the end cap. The leakproof mechanism can be used for effectively preventing the splash produced during the welding from adhering to the inductive surface of a proximity switch and for preventing collision of workpieces, and is easy to maintain; the damage of the proximity switch is avoided, the production cost is lowered and the quality of products is ensured.
Description
Technical field:
The utility model relates to a kind of novel anti-leakage mechanism, particularly a kind of leakage preventing mechanism of the part built-in nut of using on weld jig.
Background technology:
In automobile body manufacture process; workpiece itself needs to install the various parts of welding; as various single smallclothes; project-welding nut, bolt etc.; owing to need the part of welded and installed too many,, will badly influence the product quality of welding work pieces so therefore in the phenomenon of welding process through regular meeting's appearance leakage weldering, wrong weldering; cause product percent of pass low, reprocess problems such as cost height.
Summary of the invention:
The purpose of this utility model provides a kind of weld jig mistake proofing sensor attachment mechanism, and splashing of producing when it can effectively prevent to weld is bonded near on the sensitive surface of switch and the collision of workpiece; Easy care; Avoided damage, reduced production cost, guaranteed the quality of product near switch.
Technical scheme: a kind of novel built-in welded nut leakage preventing mechanism, it comprises proximity transducer; One end of sleeve is connected with end cap, and proximity transducer passes end cap, and proximity transducer is connected with end cap, and an end of test pin is arranged in the sleeve, and the other end of test pin passes sleeve, is provided with wear-resistant sleeve between sleeve and the test pin; One end of spring is enclosed within on the test pin, and the other end of spring withstands on the end cap.
The beneficial effects of the utility model: a kind of novel built-in welded nut leakage preventing mechanism, it adopts the mode of test pin to detect whether leak the weldering nut on the workpiece, it is provided with sleeve, and splashing of producing when it can effectively prevent to weld is bonded near on the sensitive surface of switch and the collision of workpiece; Easy care; Avoided damage, reduced production cost, guaranteed the quality of product near switch.
Description of drawings:
Fig. 1: be structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of novel built-in welded nut leakage preventing mechanism, one end of sleeve 3 is connected with end cap 2, proximity transducer 1 passes end cap 2, and proximity transducer 1 is connected with end cap 2, one end of test pin 5 is arranged in the sleeve 3, and the other end of test pin 5 passes sleeve 3, is provided with wear-resistant sleeve 6 between sleeve 3 and the test pin 5; One end of spring 4 is enclosed within on the test pin 5, and the other end of spring 4 withstands on the end cap 2; When having nut 8 to exist on the workpiece 7, test pin 5 is withstood by nut 8, and toward sleeve 3 interior pumpbacks, this moment, proximity transducer 1 was sensed test pin 5, promptly allowed the welding gun welding; When nut 8 leaked weldering, test pin 5 can pass from workpiece 7 unthreaded holes of project-welding nut, and proximity transducer 1 detects less than test pin 5, and then do not allow welding gun welding because proximity transducer 1 no signal is sent this moment.
