Detailed description of the invention
As shown in figs. 1 to 6, a kind of nut screwing clamping anti-rotation device, comprises bearing 1 and turning arm 2, and bearing 1 is fixed on fixture 11, and bearing 1 end is provided with mounting screw, is fixed by screws on fixture 11.Bearing 1 is the tubular structure of hollow, and inner barrel socket rotating shaft 5, rotating shaft 5 can slide up and down and rotate around its axis.Rotating shaft 5 upper end is fixed in turning arm 2 one end, and rotates rising with it and rotate rising, and turning arm 2 other end is provided with anti-rotation chuck 3.
As shown in Figure 1, anti-rotation chuck 3 is provided with the channel-shaped structure of clamping hole 4 for bottom, and wherein the shape of clamping hole 4 can have polytype, can change according to clamped nut shape.When nut is clamped in square clamping hole 4, nut is fixed, and can effectively prevent from rotating in nut mounting process skidding.
In addition, the inner barrel of bearing 1 is also provided with spring 6, spring 6 lower end is fixed on the bottom of cylindrical shell, the other end is connected with the lower end of rotating shaft 5, it is rotatable that the end of rotating shaft 5 is connected with the end of spring 6, can not produce restoring force circumferentially like this at rotating shaft 5 when rotating around its axis.Rotating shaft 5 is in rising, and spring 6 is in the state be stretched.
The axis body of rotating shaft 5 is fixed with pin 7 radially, bearing 1 barrel offers the first chute 8 and the second chute 9 of corresponding pin 7, wherein the first chute 8 is arranged along bearing 1 tubular axis direction, second chute 9 is along bearing 1 cylindrical shell circumferential directions, and the first chute 8 is communicated with the second chute 9.Pin 7 is slidably connected in the first chute 8 and the second chute 9.
The pulling force effect of spring 6 can be subject to like this, because spring now 6 is in by the state of stretch-draw when pin 7 slides up and down in the first chute 8 time.When pin 7 runs in the second chute 9, by the barrier effect of barrel, pin 7 along the circumferential direction can move in the second chute 9, and turning arm 2 can realize rotating the position regulating clamping nut.
In order to when spring 6 retracts to lowermost end, fix turning arm 2 and prevent it from rotating, the upper end of bearing 1 is also provided with holddown groove 10, turning arm 2 when pin 7 is positioned at the lower end of the first chute 8 and holddown groove 10 be connected together.Like this, rotated by the effect restriction turning arm 2 of holddown groove 10.
During assembling, manually rotating shaft 5 is upwards stretched, spring 6 is in extended state, the position of adjustment turning arm 2 is to the A position in Fig. 6, connected nut is overlapped by the clamping hole 4 on upset chuck 3, unclamp turning arm 2, pin 7 slides in the first chute 8, utilizes the pulling force effect of spring 6 to make turning arm 2 clamp workpiece 12.Now turning arm 2 enters into holddown groove 10 and can not rotate, and completes the clamping of turning arm 2 pairs of Triangular Arm workpiece 12, then tights a bolt, complete installation process.
After completing the installation of screw bolt and nut, hand hoisting turning arm 2, clamping hole 4 and nut are thrown off, then rotates turning arm 2, pin 7 is slided in the second chute 9, turning arm 2 is rotated to the position not stopping workpiece 12, stop the rotation, namely turning arm 2 is arranged in the B position of Fig. 6, now, take off workpiece 12 from fixture 11, complete whole installation process.
The utility model, by effect clamping nut while turning arm and anti-rotation chuck, avoids and occurs the phenomenon that nut rotation skids improve installation effectiveness in the process of construction bolt, reduce installation difficulty, decrease the set-up time, and structure is simple, has great promotional value.
