Utility model content
The purpose of this utility model is: propose a kind of for stator structure fixing, that connect, locate long stroke redundance linear movement pick-up.
The technical solution of the utility model is: a kind of long stroke redundance linear movement pick-up stator structure, comprise front plug 4, rear plug 5, stator case 3, front plug pilot hole bung flange 1, it is characterized in that: front plug 4, rear plug 5 and stator case 3 form housing parts; On front plug 4 and rear plug 5, be respectively arranged with corresponding pilot hole 12; There is the through hole 15 that can make sensor pass through at stator case 3 middle parts, and each single long stroke remaining linear movement pick-up passes after the pilot hole of pilot hole 12, through hole 15 and rear plug 5 of front plug 4 successively, is fixed on housing parts by front plug 4 pilot hole bung flanges 1.
On rear plug 5, there is stepped hole 13, on front plug 4, have screw thread 14 to coordinate with front plug pilot hole bung flange 1 and realize the fixing of linear movement pick-up; Pilot hole 12 has position degree and accuracy requirement to realize the positioning requirements of long stroke redundance linear movement pick-up, and housing 3 middle parts have through hole 15 to guarantee the resistance to mechanical vibration requirement of long stroke sensor.On above-mentioned front plug 4, rear plug 5, stator case 3, have lightening hole 11.
The utility model has the advantages that: for long stroke sensor request for utilization, adopt novel stator structure to solve the problem that conventional structure technique cannot realize, realizing remaining linear movement pick-up stator fixes, connects and locate, meet the request for utilization of long stroke sensor precision, remaining consistance and reliability, also can alleviate product weight simultaneously.
