Abstract

(57) [Summary] [Purpose] To provide a temporary fixing jig for nuts that can be tightened with appropriate strength in a short time when attaching nuts to bolts. [Structure] By rotating a rubber roller 3 attached to a drive shaft of a motor 1 and pressing a nut 8 attached to a tip portion of a bolt against the rubber roller 3, the nut 8 is attached to a bolt 7
A nut temporary fixing jig characterized by moving to a predetermined position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nut attaching / detaching jig for carrying nuts attached to bolts to a predetermined position, tightening or removing them.

[0002]

2. Description of the Related Art Conventionally, when an electronic component is mounted on a board or a device, necessary nuts are attached to bolts and terminals of the electronic component as accessories. To attach the nut to the bolt, tighten with an electric wrench, Or it is done manually.

[0003]

In the work of attaching the nut to the bolt, when the electric wrench is used, the nut is tightened, and the accessory attached to the bolt of the electronic component for the user to attach the electronic component to the board or the device. It was difficult to remove the nut that is the product.

Further, when the nut is attached to the bolt by hand, when the nut is removed, a proper tightening state is obtained, but there is a problem that it takes time because it is done manually.

SUMMARY OF THE INVENTION An object of the present invention is to provide a nut temporary fixing jig capable of tightening with a proper strength in a short time when attaching a nut to a bolt.

[0006]

[Means for Solving the Problems] The above-described object is to attach a rubber roller to a drive shaft of a motor, and to screw a nut attached to a bolt tip of an electronic component to a rotating rubber roller by pressing the nut to the root of the bolt. It is a jig.

That is, a nut temporary fixing jig characterized in that a rubber roller attached to a drive shaft of a motor is rotated, and a nut attached to the tip of the bolt is pressed against the rubber roller to move the nut to a predetermined position of the bolt. Can be achieved by using.

[0008]

According to the nut temporary fixing jig of the present invention, by changing the motor torque, the number of revolutions or the diameter of the rubber roller, the nut can be easily tightened in a short time and the degree of tightening of the nut can be easily removed by the user. You can now tighten it weakly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a nut temporary fixing jig of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a nut temporary fixing jig of the present invention, and FIG. 2 is a perspective view for explaining a state in which the nut is pressed against the nut temporary fixing jig to rotate the nut. ing.

In FIG. 1, a motor 1 is fixed on a pedestal 6, and a rubber roller 3 at least the outer circumference of which is made of rubber is attached to the shaft of the motor 1 via a gear (not shown) in a gear head 2.
Is provided. The rubber roller 3 can be rotated both clockwise and counterclockwise by a combination of gears in the gear head 2 when the motor 1 is driven. A protective cover 4 is fixed on the pedestal 6 in the lower half of the rotating rubber roller 3. Further, a switch 5 for driving the motor 1 is attached to the protective cover 4, and the switch 5
When put in, the rubber roller 3 rotates in the direction of arrow 9.

The operation of temporarily screwing the nut into the bolt of the electronic component by the temporary nut fixing jig will be described below with reference to FIG.

In FIG. 2, when the nut 8 attached to the tip of the bolt 7 of the electronic component is pressed against the rotating rubber roller 3, the nut 8 indicates the direction of rotation of the rubber roller 3 as indicated by the arrow 9.
It is rotated in the direction of the arrow 10 opposite to the above. Therefore, the nut 8 moves in the direction of the arrow 11 to the root of the bolt of the electronic component. Further, the moving speed of the nut is proportional to the peripheral speed of the rubber roller 3, and the tightening force of the nut is proportional to the torque of the motor 1. Therefore, in order to change the moving speed and the tightening force of the nut, the inside of the gear head 2 shown in FIG. Change the gear ratio of the rubber roller 3
It can be easily changed by changing the diameter of.

[0014]

As described above, according to the nut temporary fixing jig of the present invention, it is possible to provide a nut temporary fixing jig capable of tightening with a proper strength in a short time when the nut is attached to the bolt. Can improve work efficiency.
