The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
The anti-fall mechanism of robot arm as shown in Figure 1-Figure 3, the utility model is that a kind of band signal detects, the anti-fall mechanism of feedback device.Comprise anti-fall cylinder, magnetic valve and air pressure protection switch.
Anti-fall cylinder comprises cylinder body 1, and piston 9 is set in cylinder body, and guidance tape 8 and C type circle 10 are housed on the piston 9; Piston 9 two ends are equipped with secondary piston bar 5 and back piston bar 12 respectively, and its connected mode is for being threaded, and make cylinder body form two cavitys of A, B; Secondary piston bar 5 is equipped with drive end bearing bracket 4 with cylinder body 1 front end junction, dust ring 6, end cap O type circle 2 and piston rod O type circle 3 is housed successively below the drive end bearing bracket 4, and the hole is equipped with back-up ring 7 in drive end bearing bracket 4 and cylinder body 1 junction; Being with on the back piston bar 12 resets uses spring 11, and back piston bar 12 is equipped with spring seat end cover 14 with junction, cylinder body 1 rear end, and spring seat end cover 14 is equipped with dust ring 15 with back piston bar contact site; Cylinder body 1 is provided with two holes, and Kong Yiyong sintered copper bead seal pretends to be noise elimination post 13 that hole two is used for installing gas-tpe fitting 16.
