Embodiment Construction

[0034] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0035] Such as figure 1 and figure 2 A three-jaw manipulator driven by a rotary cylinder includes a support housing 2 , a sliding seat 5 mounted on the support housing 2 , and three sliders 7 arranged on the sliding seat 5 . Each slider 7 is provided with a jaw 8 . When the sliding seat 5 and the supporting shell 2 are closed and installed, a cavity is formed, and a driving wheel 4 is arranged in the cavity, and a rotating cylinder 1 is installed on the lower end of the supporting shell 2, and the rotating cylinder 1 is driven by the positioning bushing 3 The driving wheel 4 rotates in the cavity. The support housing 2 is in the shape of a "concave" cylinder, and the cavity is a circular cavity, which is convenient for the driving wheel 4 to rotate in the cavity. The sliding seat 5 is a circular panel, which can cover the uppe...

Abstract

The invention relates to a three-jaw mechanical hand driven by a rotary air cylinder. The three-jaw mechanical hand comprises a supporting shell, a slide base which covers the supporting shell, and three slide blocks which are arranged on the slide base, wherein a clamping jaw is arranged on each slide block; a cavity is formed when the slide base covers the supporting shell, a drive wheel is arranged in the cavity, the lower end of the supporting shell is equipped with a rotary air cylinder, and the rotary air cylinder drives the drive wheel to rotate in the cavity through a positioning shaftsleeve; three arc-shaped guide slots are formed in the drive wheel, the three arc-shaped guide slots are distributed in the drive wheel in a centro-symmetric mode, three centripetal linear guide slots are formed in the slide base, the centripetal linear guide slots are connected with the arc-shaped guide slots through drive slide wheels, the drive slide wheels drive the slide blocks to slide towards the centripetal linear guide slots, and the clamping jaws are driven to open or close to clamp or loosen workpieces. The three-jaw mechanical hand converts rotary motion of the rotary air cylinderinto linear motion of the clamping jaws, so that opening and closing of the clamping jaws are realized.

Description

technical field [0001] The invention relates to a three-claw manipulator driven by a rotary cylinder. Background technique [0002] At present, pneumatic grippers are widely used in the automatic production process to realize the clamping and handling of workpieces. As a kind of pneumatic gripper, the three-jaw manipulator is used to grab the inner and outer diameters of circular parts, and has the characteristics of self-centering and large load torque. At present, the commonly used three-jaw manipulators have wedge-shaped slider type and crank-slider type structure. The stroke is generally small, and the model size is relatively concentrated. Higher requirements are put forward in terms of stroke, clamping force, and self-locking in the working process. When designing non-standard equipment, it is often impossible to select a suitable pneumatic gripper. [0003] For example, in the patent of a three-claw manipulator with application number 1320076755.0, the claw fingers ...
