Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a component gripping device, and more specifically, it has a link-type parallel chuck that operates using air as a driving source, and a fixed V-shaped reference block. The present invention relates to a component gripping device equipped with a component gripping device.

Configuration of conventional examples and their problems Conventional component gripping devices have link-type parallel chucks that operate using air as a driving source, but the positioning accuracy when gripping an object is dependent on the links, pivots, and Since it is affected by the accuracy of the links and the continuous parts of the links, the positioning accuracy of the article becomes unstable, and there is a drawback that reliability and stability are poor when automatically handing over the article with an automatic production machine.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and has a link-type parallel chuck operated by air as a driving source, a fixed V-shaped reference block, and a simple construction. It is an object of the present invention to provide an optimal component gripping device that makes it possible to improve the positioning accuracy of articles, and also to improve the reliability and stability of article delivery.

Structure of the Invention The component gripping device of the present invention includes a piston that moves linearly using pressure fluid, a fluid pressure cylinder having a pressure fluid connection port, and a cylinder cover provided with a pressure fluid connection port to configure the fluid pressure cylinder. and,
a rod constituting the other end of the piston, a link connected to the rod, a main body case integral with the fluid pressure cylinder, an arm pivotally supported by the main body case and connected to the link, and an arm connected to the main body case. The device includes a pivoted lever, a claw connected to the arm and the lever and having one end tapered, and a reference block attached to the main body case having a V-shaped portion, and the reference block is attached to the main body case to move the fluid pressure cylinder for a predetermined stroke. By operating within the range, the claws move in parallel and can grip a cylindrical article using the V-shaped portion of the reference block as a reference, and the simple structure improves the positioning accuracy of the article. Furthermore, it is possible to realize a component gripping device that can improve the reliability and stability of article delivery.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
This will be explained based on the diagram.

A piston 4 that moves linearly using pressure fluid, for example air, a fluid pressure cylinder 3 having a pressure fluid connection port 1, and a cylinder cover 2 provided with the pressure fluid connection port 1 to configure the fluid pressure cylinder 3.
, a rod 5 forming the other end of the piston 4, a link 6 connected to the rod 5, a body case 16 integral with the fluid pressure cylinder 3, and a link 6 that is pivotally supported 8 by the body case 16. an arm 7 connected to the main body case 16, a lever 10 pivotally supported 9 to the main body case 16, a claw 11 connected to the arm 7 and the lever 10 and having one end tapered 12;
It consists of a reference block 13 to which the main body case 16 having a letter-shaped portion 14 is attached.

The operation of the component gripping device configured as described above will be explained below.

When pressure fluid, for example air, is sent from the pressure fluid connection port 1 of the cylinder cover 2 to the fluid pressure cylinder 3 to move the piston 4 forward, the rod 5 moves forward and the arm 7 and lever 10 are moved through the link 6. , swings relative to the shaft supports 8 and 9.

Then, the claws 11 perform a parallel motion and operate in a direction to grip the cylindrical article 15. During its operation, the article 15 is pushed against the taper 12 of the pawl 11 and positioned along the V-shaped portion 14 of the reference block 13.

Therefore, the positioning accuracy when gripping the article 15 is improved regardless of the backlash of the link 6, arm 7, and lever 10, and the tapered shape 12 of the claw 11 presses the article 15 against the reference block 13. Therefore, the article 15 is stabilized in the gripped state.

As described above, according to the present invention, it is possible to improve the positioning accuracy of articles with a simple configuration, and also to provide an optimal component gripping device that makes it possible to improve the reliability and stability of article delivery. Can be provided.

Effects of the Invention As described above, the component gripping device of the present invention has a link-type parallel chuck that operates using air as a driving source, has a tapered claw for gripping an article, and has a fixed V-shape. Equipped with a reference block that
The simple configuration makes it possible to improve the positioning accuracy of articles.

Furthermore, since the automatic delivery of goods has the advantage of being highly reliable and stable, the apparatus has great economic effects and has excellent practical effects.
