Description
Technical field
The utility model relates to proximity transducer.
Background technology
Adopt proximity transducer to control the riding position of welding part on frock clamp on the welding streamline, because the welding job environment is more abominable, the weld job of welding robot causes splashes and scorches reasons such as proximity transducer, it is very high to cause proximity transducer to damage the frequency, and because the installation site of many proximity transducers is special, it is also very high therefore to be broken the frequency of proximity transducer by miscellaneous part.
The utility model content
The purpose of this utility model is to provide the proximity transducer with protective device, to protect proximity transducer to avoid being collided by extraneous parts effectively or welding spark scorches.
For realizing the proximity transducer with protective device of described purpose; be characterized in comprising the bakelite protective sleeve; metal protection protector; push rod and proximity transducer; proximity transducer has induction end; the induction end of proximity transducer is in the bakelite protective sleeve; the bakelite protective sleeve outside puts metal protection protector; metal protection protector and bakelite protection are with corresponding through hole; push rod is inserted in this through hole movably; the outer end of push rod exposes to metal protection protector and the inner is positioned at the bakelite protective sleeve; be provided with back-moving spring between the outer end of push rod and the metal protection protector, the inner of push rod is relative in the bakelite protective sleeve with the induction end of proximity transducer.
Described proximity transducer with protective device, its further characteristics are that the inner attaching nut of push rod is to prevent to deviate from from the bakelite protective sleeve.
Described proximity transducer with protective device, its further characteristics are that there is external thread the end of the insertion push rod of metal protection protector, is engaged with nut on the external thread.
Described proximity transducer with protective device, its further characteristics be, there is external thread in the outside of bakelite protective sleeve, is exposed at outward on the external thread of metal protection protector and is engaged with nut.
Described proximity transducer with protective device, its further characteristics be, there is external thread in the outside of proximity transducer, is exposed at outward on the external thread of bakelite protective sleeve and is engaged with nut.
The utility model is improved to the front end push rod with Non-Contact Proximity Sensor and contacts with workpiece or anchor clamps, push rod backhaul inductive proximity sensors, effect reaches former designing requirement, that has avoided that welding robot causes when work the factor of damaging proximity transducer such as splashes, scorches, and also avoids the factor that breaks when parts are put into frock clamp simultaneously.Save transposing proximity transducer expense greatly, the length of push rod can be regulated the proximity transducer stroke.

Fig. 2 is the semisectional view with proximity transducer of protective device.
Embodiment
As depicted in figs. 1 and 2, the proximity transducer with protective device comprises bakelite protective sleeve 1, metal protection protector 2, push rod 3 and proximity transducer 4, and proximity transducer 4 has induction end 41.
The induction end 41 of proximity transducer 4 is inserted in the bakelite protective sleeve 1 from first end (lower end) of bakelite protective sleeve 1.Bakelite protective sleeve 1 outside puts metal protection protector 2; metal protection protector 2 and bakelite protective sleeve 1 have corresponding through hole; push rod 3 is inserted in this through hole movably; the outer end of push rod 3 exposes to metal protection protector 2 and the inner is positioned at bakelite protective sleeve 1; be provided with back-moving spring 5 between the outer end of push rod 3 and the metal protection protector 2, the induction end 41 of the inner of push rod 3 and proximity transducer 4 is relative.But the inner attaching nut 72 of push rod 3 is to prevent to deviate from from bakelite protective sleeve 2.There is external thread the end of the insertion push rod 3 of metal protection protector 2, can be fixedly connected on the relevant position by means of nut 71.Also there is screw thread in the outside of bakelite protective sleeve 1, by means of the induction end 41 of nut 73 scalable proximity transducers 4 and the distance of reaction between the push rod 3.Also there is external thread in the outside of proximity transducer 4, can fixedly connected miscellaneous part by means of nut 74.
Bakelite protective sleeve 1 plays isolated induction end 41, prevents improper signal source interference.Previous embodiment is improved to front end push rod 3 with Non-Contact Proximity Sensor 4 and contacts with workpiece or anchor clamps, push rod 3 backhaul inductive proximity sensors 4, and effect reaches former designing requirement.That has avoided that welding robot causes when work the factor of damaging proximity transducer such as splashes, scorches, and also avoids the factor that breaks when parts are put into frock clamp simultaneously.Save transposing proximity transducer expense greatly.
The length of push rod 3 can be regulated the proximity transducer stroke.
