As shown in Figures 1, 2, 5 and 6, a carbon-free trolley fine-tuning mechanism includes an XY-axis mover, an X-axis mover and a Y-axis mover, and the X-axis mover and Y-axis mover are perpendicular to each other. The XY-axis mover includes a carrier plate 1, a guide rod 2, a slider 3 and a rubber band connector connected up and down in sequence. The slider 3 can move left and right along the guide rod 2; the carrier plate 1 is connected with the Y-axis mover, and the slide Block 3 is connected with the X axis mover. Since the X-axis mover is connected to the slider 3, and the Y-axis mover is connected to the carrier plate 1, the X-axis mover and the Y-axis mover can work together to connect the rubber band connected to the slider 3 when in use. Even if the X-axis mover slides horizontally on the guide rod 2 with the slider 3 to realize the movement of the rubber band connector in the horizontal direction, the Y-axis mover moves vertically with the slider 3 and the guide rod 2 at the same time. The movement realizes the movement of the rubber band connector in the vertical direction, so that the horizontal position of the rubber band connector can be adjusted by the X-axis mover, and the vertical position of the rubber band connector can be adjusted by the Y-axis mover.

The rubber band connector includes a screw box 4 and a screw 5. The middle part of the screw 5 is provided with a first through hole 6, and the lower part is provided with threads. There is a rubber band, and the rubber band controls the position change of the rubber band connector.

When the present invention is in use, the rubber band is worn and bound in the first through hole 6, and the bottom of the screw 5 is screwed into the screw box 4. In detail, one end of the rubber band is fixed on the screw 5, and the other end can be connected with the mechanism of the cam mechanism of the carbonless trolley, so that the elastic force of the rubber band on the mechanism can be fine-tuned while the position remains unchanged. Then use the X-axis mover to control the position of the rubber band in the horizontal direction, use the Y-axis mover to control the position of the rubber band in the vertical direction, and use the rubber band connector to achieve fine-tuning of the position.

As shown in Figure 3, the Y-axis mover includes a first cylinder 7 and a first screw 8, the first cylinder 7 is connected to the first screw 8, and the first screw 8 is covered with a carrier plate from bottom to top 1 and the first screw connector 9, the first screw connector 9 is connected with the carrier board 1, the first screw rod 8 is rotated by rotating the first cylinder 7, and the first screw rod 8 drives the carrier board 1 to move up and down. When in use, rotate the first cylinder 7, the first screw mandrel 8 rotates with the first cylinder 7, the first screw mandrel connector 9 moves up and down on the first screw mandrel 8, because the first screw mandrel connector 9 and the load The boards 1 are connected, and the carrier board 1 moves up and down on the first screw rod 8 along with the first screw rod connector 9 to realize the movement of the XY axis mover and the rubber band connector in the Y axis direction.

As shown in Figure 4, the X-axis mover includes a second cylinder 10 and a second screw 11, the second cylinder 10 is connected to the second screw 11, and the second screw 11 is covered with a screw box 4 from right to left , rotating the second cylinder 10 makes the second screw 11 rotate, and the second screw 11 drives the screw box 4 to move left and right, so as to realize the movement of the XY axis mover and the rubber band connector in the X axis direction.

Further, the screw box 4 is a square body, and a screw hole is provided on the top of the screw box 4, and the bottom of the screw 5 is screwed into the screw hole; the left and right sides of the screw box 4 are perforated with a second through hole 13, through which the second The through hole 13 is sleeved on the second screw mandrel 11, so that the second screw mandrel 11 drives the screw box 4 to move left and right.

Furthermore, five screw holes are arranged on the top of the screw box 4, and the five screw holes are respectively arranged on the four corners on the top of the screw box 4 and the middle part of the screw box 4. The five screws 5 are all used to connect the rubber bands, so that the adjustable range of the original length of the rubber bands becomes larger. At the same time, under the joint force of multiple rubber bands, it not only breaks the limitation of fine-tuning the force of one rubber band, Moreover, the fixed relative positions between the multiple rubber bands make the resultant force of the multiple rubber bands on the fine-tuning mechanism or the stress relationship of each rubber band calculable, which reduces the limitation of the fine-tuning mechanism and makes the fine-tuning of the carbon-free trolley more accurate. mathematical basis.

The tops of the first cylinder 7 and the second cylinder 10 are all provided with a word boss, and the ends of the first screw mandrel 8 and the second screw mandrel 11 are correspondingly provided with a word concave hole, and the word boss and the word concave hole are paired and connected. Preferably, the first cylinder 7 is detachably connected to the first screw rod 8 , and the second cylinder 10 is detachably connected to the second screw rod 11 . In detail, the slotted boss of the first cylinder 7 is paired with the slotted hole of the first screw 8, and the slotted boss of the second column 10 is paired with the slotted hole of the second screw 11. When needed, only need to rotate the first cylinder 7 or the second cylinder 10 to drive the rotation of the first screw mandrel 8 and the second screw mandrel 11 respectively. After the adjustment is completed, the first cylinder 7 and the second cylinder 10 can be disassembled to make the Debugging is more convenient and labor-saving.

As shown in Figure 7, a carbon-free trolley includes the above-mentioned fine-tuning mechanism for the carbon-free trolley. The carbon-free trolley includes a bottom plate 14, and a bracket 15 is arranged on one side of the bottom plate 14.

Since the aperture of the third through hole 12 is smaller than the horizontal section diameter of the first cylinder 7, when the first cylinder 7 is rotated, the first cylinder 7 and the first screw mandrel 8 will not move up and down together when the first cylinder 7 rotates. Situation, can guarantee the effect of first screw mandrel connector 9 moving up and down like this.

When the carbon-free trolley of the present invention is in use, rotate the first cylinder 7 to adjust the vertical position of the rubber band connector to achieve the effect of lifting, and rotate the second cylinder 10 to adjust the horizontal position of the rubber band connector to realize The effect of moving left and right. And the rubber band is connected with the rubber band connector, that is, by twisting the first cylinder 7 and the second cylinder 10 respectively, the vertical and horizontal positions of the end points of the rubber band can be adjusted, so that the impact of the rubber band on other mechanisms of the trolley can be adjusted. direction of force. At the same time, the elongation of the rubber band can be adjusted by twisting the screw 5 connected together with the rubber band, that is, the elastic force output by the rubber band is adjusted. Compared with the fine-tuning of the rubber band without the fine-tuning mechanism, such a fine-tuning mechanism can make the fine-tuning of the rubber band more convenient and efficient. In addition, the fine-tuning mechanism is highly transplantable, and the size parameters of the fine-tuning mechanism only need to be scaled according to the size of the carbon-free trolley, and the modified mechanism can be added without much modification to the carbon-free trolley.

Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
