Embodiment Construction
[0027] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0028] Such as Figure 2-5 As shown, a fast-moving and precisely positioned transmission device includes a screw, a half-round nut, a rotating rod, a rotating handle, a slider, and a guide rail; the screw and the guide rail are parallel to each other, and the slider is slid on the guide rail, rotating The rod runs through the slider and is perpendicular to the screw rod. The rotating rod is flexibly connected to the slider. One end of the rotating rod facing the screw rod is connected to the half-round nut. The other end of the rotating rod is provided with a rotating handle. When the rotating rod rotates, the half-round nut does not follow the rotation. When...

Abstract
The invention discloses a transmission device with rapid moving and precise positioning functions as well as a using method thereof. The transmission device comprises a lead screw, a semicircular nut, a rotary rod, a rotary handle, a slide block and a guide rail. The using method comprises the following steps: step 1, pulling the semicircular nut out of the lead screw; step 2, rapidly moving the semicircular nut; step 3, meshing the semicircular nut with the lead screw again; and step 4, achieving position fine-tuning. Compared with the prior art, the transmission device and the using method disclosed by the invention have the beneficial effects that the purpose of rapid moving can be fulfilled by releasing the semicircular nut from the lead screw and meshing the semicircular nut with the lead screw again; the adjustment time is saved, and the operation is convenient and rapid; and furthermore, more precise positioning can be achieved due to the coordination with gear transmission.
Description
technical field [0001] The invention relates to a transmission device capable of rapid movement and precise positioning and a method for using the same. Background technique [0002] Among the mechanisms that require transmission, the commonly used mechanisms are screw mechanisms, rack and pinion mechanisms, etc. An example of the description of the screw drive mechanism, such as figure 1 As shown, when the slider moves from position A to position B, the hand wheel needs to rotate n times through the reduction mechanism. When it needs to move several times the distance from position A to position B, it needs to rotate several times n times. When working When frequently adjusting the position, it is necessary to shake the handwheel frequently. This method has the following defects: [0003] 1. When the moving distance is large, the handwheel needs to be rotated dozens or even hundreds of times to reach the position; [0004] 2. When the position needs to be changed frequen...
