Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of flexible contact type oil cylinder displacement sensing apparatus, its structure is shown in Fig. 1-2: this device comprises sensor, casing assembly and mounting bracket 7, sensor is located at the middle part of this device, and casing assembly is located at the outside of sensor, and mounting bracket 7 is located at the middle part of shell.Wherein, sensor is comprised of magnetic railings ruler 11 and magnetic head 14, and the bottom of magnetic head 14 arranges magnetic head spacer ring 15.Casing assembly comprises jacking block 1, protecgulum 2, sliding sleeve 3, black box 4, spring seat 5, shell 6, mounting bracket 7, spring 8, main shaft 9, copper sheathing 12, guide pad 13, magnetic head spacer ring 15, magnetic scale protecting jacket 16, magnetic head blind flange 17, bonnet 18.The inside of sliding sleeve 3 arranges copper sheathing 12; the upper interior portion of sliding sleeve 3 arranges chuck 10; chuck 10 link magnetic railings rulers 11; jacking block 1 is embedded in the top of protecgulum 2; protecgulum 2 is fixed on the top of sliding sleeve 3; main shaft 9 is arranged on the middle part of this device; magnetic head 14 is arranged on the middle part of main shaft 9; one end of magnetic head 14 arranges guide pad 13; guide pad 13 is fixed by circlip for hole; one end of magnetic head 10 arranges magnetic head spacer ring 15; magnetic head spacer ring 15 1 ends arrange magnetic scale protecting jacket 16, and an end of magnetic scale protecting jacket 16 arranges magnetic head blind flange 17, magnetic head 14; magnetic scale protecting jacket 16; magnetic head spacer ring 15; magnetic head blind flange 17 is connected and fixed by screw rod; magnetic head blind flange 17 is connected and fixed by screw and main shaft 9, and bonnet 18 is connected on the main shaft 9 through screw.
