Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Embodiment one
As shown in figs. 1 to 6, in the present embodiment, a kind of sliding block 2 of bender of the present invention and the connection of oil cylinder 1
Structure, including anti-rotation mechanism and stud 6, one end of the stud 6 spins with the piston rod 19 of oil cylinder 1, another
End spins with sliding block 2, and the anti-rotation mechanism includes the first anti-rotation mechanism and the second anti-rotation mechanism, and described first prevents certainly
Rotation mechanism is arranged on the piston rod 19, and for preventing the piston rod 19 from being rotated around its own axis, described second prevents certainly
Rotation mechanism is arranged between the stud 6 and the sliding block 2, for preventing the stud 6 around its own rotary shaft
Line.
The piston rod 19 of oil cylinder 1 is connected with the sliding block 2 of bender by stud 6, the piston rod 19 of oil cylinder 1 is by upper
Down move, drive the sliding block 2 of bender to move from top to bottom.Specifically, the piston rod 19 of oil cylinder 1 and the sliding block of bender
2 offer the screwed hole that spins for being spun with the stud 6 respectively.First anti-rotation mechanism is set, can
Prevent rotation of the piston rod 19 around its own axis, avoided when the bender works the piston rod 19 in oil cylinder 1 on toward
Piston rod 19 rotates around the axis of its body while lower motion, effectively avoid due to piston rod 19 from then cause double
Hook bolt 6 loosens, and prevents stud 6 from departing from one end that piston rod 19 spins out of piston rod 19 the hole that spins.In cunning
The side that the Cheng Zhonghui that block 2 moves causes the sliding block 2 of stud 6 to abut rubs, and is arranged on spinning on the sliding block 2
Abrasion, which occurs, for the screw thread in hole easily makes the rotation of stud 6, by setting the second anti-rotation mechanism, can prevent stud
6 rotate around its own axis, and the one end for avoiding stud 6 from being spun with sliding block 2 takes off out of the hole that spins that be arranged on sliding block 2
From.It is capable of the piston rod 19 of the anti-disengaging of limited slip block 2 oil cylinder 1 by anti-rotation mechanism, effectively prevents piston rod 19 and sliding block 2
Between connection loosening, improve bender operation when security.
Wherein, first anti-rotation mechanism includes locating part, and one end of the locating part is connected with the piston rod 19,
The other end is hung on the side of the sliding block 2, and horizontal clearance is provided between the locating part and the sliding block 2, described spacing
