Problems solved by technology
Among them, the rack and gear are used as the transmission means, although they have better rigidity, but the component cost is relatively high compared to the belt and pulley
On the other hand, using a belt with a pulley as a means of transmission has the advantage of relatively low component costs. However, because the belt is flexible, the main problem in transmission is insufficient rigidity, especially when the distance to be transmitted by the belt is relatively long. When it is longer, the belt will deflect due to insufficient tension provided, and the problem of insufficient rigidity will be more obvious, resulting in poor precision of the slider transmission
[0004]
Therefore, how to solve the problem of the above-mentioned conventional sliding seat transmission, especially the obvious insufficient rigidity of the belt transmission, is the key point of the present invention.

The invention provides a belt moving mechanism with rigidity improvement, which comprises a base, a sliding seat, a driving unit, a positioning belt and a transmission belt, the sliding seat is arranged on the base and can slide back and forth along a straight line direction, the driving unit is arranged on the sliding seat, two ends of the positioning belt and two ends of the transmission belt are fixedly arranged on the base and are respectively provided with a tooth row, tooth rows of the positioning belt and the transmission belt are oppositely meshed, and a winding section is wound out ofthe positioning belt to be wound on a driving wheel of the driving unit in a meshed transmission mode. When the driving wheel rotates, the winding section is driven to continuously change the position on the transmission belt, meanwhile, the sliding seat is dragged to slide on the base in the linear direction, rigidity is improved through combination of the positioning belt and the transmission belt, and therefore the device is formed.
Description
technical field [0001] The invention relates to a transmission mechanism of mechanical equipment, in particular to a belt moving mechanism with rigid lifting. Background technique [0002] At present, industrial mechanical equipment, such as the workbench where the machine tool drives the workpiece to move, or the tool removal mechanism of the tool changer, often requires linear movement in one or more axes, so there will be slippage on the mechanical equipment. necessary for seat installation. Generally, it is better to use a servo motor with a lead screw as the transmission means for the drive of the sliding seat. Although it can meet the requirements of high movement precision, the component cost is relatively high. [0003] In order to reduce the cost of sliding seat drive, some sliding seats use racks and gears as transmission means, and some sliding seats use belts and pulleys as transmission means. Among them, the rack and the gear are used as the transmission means...
