Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hand-held gripping device for workpieces, parts, etc. used in the assembly and production of electronic equipment, precision machinery, etc.

[Conventional technology]

BACKGROUND OF THE INVENTION Electronic devices, precision machines, etc. are becoming smaller and their performance is improving, and the parts used therein are also becoming extremely smaller.

As a result, it has become difficult to handle the parts with human fingers, and so-called tweezers have been used in the assembly and production of electronic devices and precision machines.

[Problem that the invention attempts to solve]

The use of the tweezers and the like requires skill and has the disadvantage that both hands cannot be used effectively.

That is, it requires skill to maintain a constant gripping state with the fingers of one hand and work with the remaining hand.

This invention allows anyone to quickly grasp and release parts by operating a switch, and furthermore, there is no need to maintain the gripping state with fingers etc. after gripping until it is released, increasing work efficiency. This is something that can be achieved.

[Means for solving problems]

This invention solves the above problems,
The piston portions of the gripping claws each having a piston at the rear end are adapted to face each other in a cylinder provided in the gripping portion main body, and a cylindrical handle having a switch is integrally provided at the rear of the gripping portion main body, and the cylinder One of the two ventilation passages consisting of an air hose extending inside and behind the handle communicates with the inner compartment of the cylinder, and the other communicates with the outer compartment.

[Effect]

In the present invention having the above structure, the air hoses 5 and 6 constituting the two ventilation paths 3 and 4 and the lead wire 8 from the switch 7 are connected to the control box 27.

Then, when the handle 2 is held in the hand and the switch 7 is operated, the solenoid valve provided in the control box 27 is switched, and the control box 2
Compressed air is supplied to one air hose 5 or 6 from a compressed air supply source such as a compressor provided in 7, and exhausted from the other air hose 6 or 5.

As a result, the inner compartment 18 of the cylinder 13
Alternatively, compressed air is supplied to the outer compartment 19,
When compressed air is supplied to the outer compartment 19, the gripping claws 11 and 12 are moved inward to grip the component X, and on the other hand, when compressed air is supplied to the inner compartment 18, The grip on the gripped component X is released.

In the present invention, the above operation is carried out by holding the two cylindrical handles in the hand, and an air hose is connected to the rear of the handle to facilitate hand-held movement. Further, the shapes of the gripping claws 11 and 12 are changed as appropriate depending on the parts X to be gripped.

Similarly, the gripping force and moving distance of the gripping claws 11 and 12 are also controlled according to the parts X to be gripped.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 and 2, 1 is a grip main body;
2, 2a are cylindrical handles integrally provided at the rear of the grip body 1; 3, 4 are two ventilation passages; 5,
6 is an air hose constituting the ventilation paths 3 and 4, 7 is a switch, and 8 is a lead wire.

First, an example of the gripping unit body 1 will be described. As shown in FIG. 4, the piston 9 portions of the gripping claws 11 and 12, which have a piston 9 and a rack 10 at their rear ends, are fitted opposite each other within a cylinder 13 provided inside, and the gripping claws 11 and 12 are configured to move in opposite directions.

In the case of the illustrated embodiment, the cylinder 13 is composed of a pipe 14 serving as a cylinder tube, a flange 15 provided around the outer surface of each piston 9, and a body-side fitting portion 16 that fits inside each flange 15. ing.

In the figure, reference numeral 17 denotes a partition wall provided at the center of the inside of the pipe 14.

In the above configuration, each cylinder 13 includes two inner compartments 18 and two outer compartments 19.

Next, the piston 9 is inserted between the main body side compatible part 16.
and a shaft 20 penetrating the partition wall 17, a through hole 21 provided from one end of the shaft 20 communicates with the outer compartment 19 via a through hole 22, and a through hole provided from the other end of the shaft 20. 23
are each opened into the inner compartment 18.

The through holes 21 and 23 provided at both ends of the shaft 20 are communicated with the main body side through holes 24 and 25 and opened to the outside.

In the figure, 26 is a synchronizing pinion.

Next, at the rear of the grip main body 1, cylindrical handles 2 and 2a having a switch 7 are integrally provided.

Two ventilation passages 3 and 4 are constituted by air hoses 5 and 6 extending inside and behind the cylindrical handles 2 and 2a;
is communicated with the inner compartment 18 of the grip main body 1.

That is, specifically, the ventilation path 3 is suitably connected to the main body side through hole 24 of the grip main body 1.

Further, the other ventilation path 4 is connected to the grip main body 1.
and the outer compartment 19 of the. Specifically, the ventilation passage 4 is suitably connected to the main body side through hole 25 of the grip main body 1.

In the present invention having the above structure, the air hoses 5 and 6 constituting the two ventilation paths 3 and 4 and the lead wire 8 from the switch 7 are bundled to form the control box 27.
guided by.

The control box 27 is provided with a compressed air supply source such as a compressor, a solenoid valve, etc. inside the control box 27, although its details are not shown. It is configured so that air can be supplied and exhausted from the other air hose 6 or 5.

FIG. 5 shows connectors 31 and 32 that integrally connect air hoses 5 and 6 and lead wires 8 for convenience when the control box 27 is shared and the grip body 1 is exchanged for various parts.
It is shown.

That is, after fitting the air hoses 5, 6 and 8 parts of the lead wires of the respective connectors 31, 32, it is sufficient to screw and tighten the nut 29 having the female thread 28 to the male thread 30 part on the control box 27 side. be.

In addition, the switch 7 in the above configuration is configured such that the first operation grips the component X, and the second operation releases the grip, and if the switch 7 is kept pressed, the grip state continues, and when the finger is released, the grip is released. It is also free to have a structure that

[Effect of idea]

According to the present invention, it is possible to easily and quickly grip and release small parts by operating a switch, thereby improving work efficiency.
