Embodiment Construction
[0015] Such as figure 1 As shown, a kind of instantaneous speed regulating device comprises lead screw 1, screw nut 2, lever 3, clutch device 4, top rod 5 and moving shaft 6, and described lead screw 1 passes through screw nut 2, and the screw nut 2 on Positioning hole 8 is arranged on connecting plate 7, and clutch device 4 with positioning shaft 9 is fixed on the connecting plate 7 of screw nut 2, and lever 3 is installed on the positioning shaft 9, and one end of lever 3 is provided with a so that moving shaft 6 can sliding device. There is a matching adjustable top bar 5 at the other end of the lever 3, and the top bar 5 is fixed on the body. The device for making the moving shaft 6 slidable is a hollow rounded rectangle 10 , and the width of the rounded rectangle 10 is greater than the diameter of the moving shaft 6 .
[0016] When the lead screw 1 is rotated to push the screw nut 2 to move in translation, the lever 3 will move in translation under the combination of th...

The invention discloses an instantaneous speed regulation device which comprises a lead screw, a nut, a lever, a clutch device, an ejector rod and a moving shaft. The lead screw penetrates the nut, positioning holes are formed in a connecting plate on the nut, the clutch device with a positioning shaft is fixed onto the connecting plate of the nut, the lever is mounted on the positioning shaft, and a device capable of driving the moving shaft to slide is arranged at one end of the lever. The adjustable ejector rod which is matched with the lever is arranged at the other end of the lever and is fixed onto a machine. The device capable of driving the moving shaft to slide is a hollow rounded rectangle, and the width of the rounded rectangle is larger than the diameter of the moving shaft. The instantaneous speed regulation device has the advantages that one end of the lever moves while the other end of the lever is forced to move under the effect of a fulcrum, the instantaneous speed of the other end of the lever is different owing to an instantaneous transformation effect of the clutch device and a ratio of distances from two end points of the lever to the fulcrum, and accordingly the purpose of adjusting a lag angle can be achieved; the position of the ejector rod fixed onto the machine can be adjusted, so that wire coils with different widths can be wound, and multiple functions of the machine can be realized.
Description
technical field [0001] The invention relates to the field of rotary propulsion equipment, in particular to an instantaneous speed regulating device. Background technique [0002] The application of rotation to push the translation of the workpiece is very common. How to adjust the speed instantaneously during the translation process, especially in the process of high-speed layer winding of the metal wire, when the layers alternate with each other, it is necessary to set an angle for the cycloid, that is, the lag angle. In the case of constant cable speed, change the cable angle instantly and return. Now it is mostly solved by cams, but the precision is not ideal enough for fine wires. It is difficult to set the electrical program with the lead screw. The invention adopts a mechanical method, which can instantly adjust the lag angle, makes the setting of the electrical program simple and easy, and can adjust the lag angle and realize multiple functions of one machine. Con...
