Detailed Description
The valve rod bending device of the manual rod type gate valve is composed of a workbench 1, a rotary table 2 and a rotary motor 3, wherein the rotary motor 3 is fixedly arranged on the lower surface of the workbench 1, the rotary table 2 is arranged on the upper surface of the workbench 1, and the rotary table 3 is connected with a motor shaft of the rotary motor 3. The positive and negative switch 14 is arranged at the corner of one end of the worktable 1. The central part of the turntable 2 is provided with a central shaft 4, and a fixed shaft 5 is fixedly arranged on the turntable 2 at one side of the central shaft 4. A travel switch 6A is movably arranged on the workbench 1 on one side of the rotary disc 2 (the travel switch adopts a domestic conventional travel switch, and adopts LX19-001/111 in an LX19 series or LXK3-20S/T in an LXK3 series, the working principle is disclosed, and the inventor does not need to describe here any more), a travel switch B12 is movably arranged on the workbench 1 on the other side of the rotary disc 2, and the travel switch 6A and the travel switch B12 are spaced at 180 degrees along the circumference of the rotary disc 2 on both sides. The travel switch A6 and the travel switch B12 are respectively connected with the rotating motor 3 and the positive and negative switch 14; a touch piece A7 and a touch piece B13 are welded on the circumferential end surface of the rotary table 2 between the travel switch A6 and the travel switch B12 at intervals of 90 degrees, and the touch piece A7 and the touch piece B13 are both triangular. The touch piece 7 intermittently contacts with the travel switch 6 to realize the rotation angle control of the rotating motor 3, and further control the rotation angle of the turntable 2.
A positioning plate 8 is fixedly arranged on the workbench 1 at one end of the rotary table 2, a blocking piece 9 is movably arranged on the positioning plate 8 through an assembly shaft, one end of the blocking piece 9 extends to the rotary table 3, and the blocking piece 9 is connected with the rotary table 3 in a sliding contact manner.
