Description

Double-end grabbing device

Technical Field

The utility model belongs to the automation field relates to the clamping jaw technique, especially a double-end grabbing device.

Background

On the automatic production line, snatch or place the product through grabbing device, grabbing device's structural design needs set for according to the structure of the own of product, to some special-shaped product, how to guarantee the steadiness and the degree of accuracy of snatching, improves the efficiency of snatching simultaneously, is the problem that needs the solution.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's weak point, provide a double-end grabbing device, realize that the automation of product snatchs and places.

The utility model provides a technical scheme that technical problem adopted is:

the utility model provides a double-end grabbing device, the camera includes the backup pad, four cylinders, four clamping jaws, the guide rail, correlation sensor, two guide rails are adorned admittedly to bottom surface bilateral symmetry in the backup pad, equal slidable mounting two sliders on each guide rail, totally four sliders, four cylinders are installed to the bottom surface symmetry of backup pad between two guide rails, four cylinders and four sliders one-to-one, the cylinder passes through the connecting plate with the slider and is connected, cylinder drive slider slides on the guide rail, each slider all connects a clamping jaw, two clamping jaws that two sliders that gliding sliders are connected on same guide rail are a pair of, a pair of clamping jaw is through the clamp of relative movement or unclamp the work piece in opposite directions.

And a spring pressing block supporting plate is fixedly arranged on the bottom surface of the supporting plate between the two pairs of clamping jaws respectively, and a plurality of spring pressing blocks and a plurality of positioning pins are arranged on the bottom surface of the spring pressing block supporting plate according to the shape of a workpiece.

And a row of photoelectric switches are fixedly arranged on the supporting plate through a bracket.

And two pairs of correlation sensors are symmetrically and fixedly arranged between the two pairs of clamping jaws through a bracket connected with the supporting plate.

And the top surface of the supporting plate is provided with a shaft hole, and the shaft hole is provided with a rotating shaft which is connected with the rotating mechanism.

The utility model has the advantages that:

1. the gripping device adopts two opposite grippers to alternately grip and place products, thereby saving the production rhythm of parts.

2. Except for the positioning parts, other parts of the gripping device are made of light aluminum alloy materials, so that the weight is reduced, and the load of a conveying device connected with the gripping device is reduced.

Detailed Description

The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.

The utility model provides a double-end grabbing device, includes the backup pad, four cylinders, four clamping jaws, guide rail, correlation sensor, adorns two guide rails 6 admittedly in the bottom surface bilateral symmetry of backup pad 1, equal slidable mounting two sliders 12 on each guide rail, four sliders in total, four cylinders 8 of bottom surface symmetry installation of backup pad between two guide rails, four cylinders and four slider one-to-one, the cylinder passes through the connecting plate with the slider and is connected, and cylinder drive slider slides on the guide rail. Each sliding block is connected with a clamping jaw 2, two clamping jaws connected with the two sliding blocks sliding on the same guide rail are a pair, and the pair of clamping jaws clamp or loosen a workpiece through opposite or relative movement. And the workpiece is ensured not to move transversely during clamping. And a spring pressing block supporting plate 5 is fixedly arranged on the bottom surface of the supporting plate between the two pairs of clamping jaws respectively, and a plurality of spring pressing blocks 7 are arranged on the bottom surface of the spring pressing block supporting plate according to the shape of the workpiece and are used for ensuring that the workpiece cannot swing in the longitudinal direction. And a plurality of positioning pins 3 are fixedly arranged on the bottom surface of the spring pressing block supporting plate. A row of photoelectric switches 4 are fixedly arranged above the spring pressing block supporting plate through a support and used for detecting whether each position of a workpiece is in place or not.

Two pairs of opposite emission sensors 10 are symmetrically and fixedly arranged between the two pairs of clamping jaws through a bracket 9 connected with the supporting plate and used for detecting whether a workpiece exists or not.

The top surface of the supporting plate is provided with a shaft hole 11, and the shaft hole is provided with a rotating shaft which is connected with the rotating mechanism.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the spirit of the present invention, and these modifications and improvements are all within the protection scope of the present invention.
