Micro clamping finger air cylinder and drive method thereof

Abstract

The invention discloses a micro clamping finger air cylinder and a drive method thereof. The micro clamping finger air cylinder comprises a cylinder body, a piston body, clamping finger sliding seatsand clamping fingers. The piston body is arranged in the cylinder body and is provided with motion rods perpendicular to the surface of the piston body. The lower ends of the motion rods are fixed tothe piston rod, and the upper end of each motion rod is of a bevel structure. A reverse bevel structure corresponding to the bevel structure of the corresponding motion rod is arranged at the lower end of each clamping finger sliding seat, fixed holes are formed in the clamping finger sliding seats, the clamping finger sliding seats are connected to guide shafts in a sleeving manner through the fixed holes, and therefore the clamping finger sliding seats are driven by the motion rods to move on the guide shafts. The clamping fingers are fixedly arranged at the upper ends of the clamping fingersliding seats and move along with the clamping finger sliding seats, and then articles are clamped and fixed. The air cylinder is simple in structure and convenient to use, the stress direction is changed completely through the bevel structures, and therefore interconversion, between the vertical direction and the horizontal direction, of the stress direction of components is achieved.

Description

technical field [0001] The invention relates to the field of automation, in particular to a micro-finger cylinder and a driving method thereof. Background technique [0002] Cylinders are commonly used in industry for handling, positioning and driving other devices. In order to prevent scratching the surface of the object, the cylinder holds the object through the hole in the object. Some cylinders mainly include a cylinder body, a piston assembly installed in the cylinder body, and a plurality of jaws movably installed on the outside of the piston assembly. Pushed by the air source, the piston assembly drives the clamping assembly to clamp the object, but the devices for driving the clamping motion collected at present are relatively complicated, using gears or setting multiple piston rods to realize the clamping of the object, but These will increase the volume of the entire cylinder, and this type of cylinder has many components, which is inconvenient for maintenance.

Problems solved by technology

Pushed by the air source, the piston assembly drives the clamping assembly to clamp the object, but the devices for driving the clamping motion collected at present are relatively complicated, using gears or setting multiple piston rods to realize the clamping of the object, but These will increase the volume of the entire cylinder, and there are many components of this type of cylinder, which is inconvenient for maintenance. Therefore, we need a new type of cylinder, which can not only effectively reduce the volume of the cylinder, but also facilitate maintenance.
