Stroke amplification device

Abstract

The invention discloses a stroke amplification device, comprising a first support body (1), a second support body (2), a third support body (3), a first screw rod mechanism (4), a second screw rod mechanism (5) and a driving mechanism (6), wherein the first screw rod mechanism (4) is fixedly arranged on the first support body (1), the second support body (2) is movably arranged on the first screwrod mechanism (4), the second screw rod mechanism (5) is fixedly arranged on the second support body (2), the third support body (3) is movably arranged on the second screw rod mechanism (5), the driving mechanism (6) drives the first screw rod mechanism (4) and the second screw rod mechanism (5) to move, the first screw rod mechanism (4) drives the second support body (2) to move relative to thefirst support body (1), the second screw rod mechanism (5) drives the third support body (3) to move relative to the second support body (2), and the first screw rod mechanism (4) and the second screwrod mechanism (5) are parallel to each other. The stroke amplification device is used for the amplification of telescopic strokes.

Description

Technical field [0001] The invention relates to the technical field of telescopic drive mechanisms in mechanical equipment, and in particular to a stroke enlargement device. Background technique [0002] In mechanical equipment, telescopic motion is the most common type of motion. Many components require telescopic motion to complete the work. Generally, telescopic motion can be achieved by air cylinders, screw rods, etc. When these tools are used to achieve telescopic motion, the amount of motion is limited, such as the The maximum expansion and contraction amount does not exceed its own length, and the expansion and contraction amount of the screw rod does not exceed its own length. For long-distance expansion and contraction driving, it is necessary to adopt a longer or two consecutive cylinders and screw rods to drive. This method requires more There is a large space to install the cylinder or the screw rod, and sometimes the space in the equipment cannot be installed due to ...

Problems solved by technology

[0002] In mechanical equipment, telescopic movement is the most common kind of movement. Many parts require telescopic movement to complete the work. Usually, telescopic movement can be realized by cylinders, screw rods, etc. When using these tools to achieve telescopic movement, the amount of movement is limited, such as cylinders. The maximum telescopic amount does not exceed its own length, and the telescopic amount of the screw rod does not exceed its own length. When driving a long-distance telescopic drive, it is necessary to adopt a longer or continuously set two cylinders and screw rods to drive. This method requires more There is a large space to set the cylinder or screw, and sometimes the space in the equipment cannot be installed, so the telescopic drive cannot be realized
