DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable spot gun which is used to suspend a portable spot gun by means of, for example, a hanging fixture suspended from a ceiling or the like. It relates to a base for mounting a hanging bracket for a spot gun.

[0002]

2. Description of the Related Art Conventionally, a hanging spot mounting bracket for a portable spot gun, which has been used to suspend a portable spot gun by means of a hanging bracket and is fixed to both sides of the portable spot gun, is a gun. It is generally known that a long hole is formed along the axial direction of the hanging hole, and a pivot that can be fixed to an arbitrary position of the long hole and that is connected to both lower ends of the hanging fittings is arranged.

[0003]

By the way, in a portable spot gun, there are various types of gun arms and pressurizing cylinders as pressurizing driving devices corresponding to the workpieces, and the center of gravity of each gun is different. Also, in the same portable spot gun, it is necessary to change the suspension position depending on the hitting position of the gun. By the way, in the above prior art, since the pivots connected to both lower ends of the hanging bracket can be fixed at any positions of the elongated holes formed along the axial direction of the gun, the center of gravity of the portable spot gun is Even if the gun is displaced, there is no problem in using the portable spot gun in a horizontal state.However, when the gun is used with an inclination with respect to the horizontal direction or when the gun is used in a vertical state, There is a problem in that the center of gravity of the gun is displaced from the hanging position, and the hanging balance of the gun is lost during use of the gun, so that the gun becomes unstable and accurate welding cannot be expected.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to set a hanging position of a gun in an axial direction of the gun and in a direction perpendicular to the axial direction. The portable can be selected at any position with the center of gravity of the gun displaced, and the gun can be suspended in a stable manner in accordance with the usage posture of the gun, enabling accurate welding. It is an object of the present invention to provide a base for mounting a hanging bracket for a spot gun.

[0005]

In order to achieve the above-mentioned object, a base for mounting a hanging metal fitting for a portable spot gun according to the present invention comprises a base having a substantially fan-shaped plate in front view. A base support hole is formed under the fan, a base position adjusting slot is formed along the arc of the fan, and one side of the base is extended to form a protrusion. A pivot connected to the hanging bracket is disposed on the protruding portion, and bolts respectively inserted into the base supporting hole and the position adjusting elongated hole are formed in base mounting holes formed in the side surface of the gun. The base is fixed to the gun by screwing.

Reference numeral 8 denotes a base formed of a substantially fan-shaped plate when viewed from the front. A base support hole 9 is formed below the fan, and the base 8 extends along an arc 10 of the fan. A long hole 11 for adjusting the position of the base is formed, and one side of the base 8 is extended to form a protruding portion 12. The protruding portion 12 is formed at the lower end of the hanging metal fitting 7. A pivot 14 connected to the bore 13 is arranged.

Reference numerals 15 and 15 denote base mounting members disposed on both lower side surfaces of the fixed arm 6 of the portable spot gun 1. Each base mounting member 15 has an axial direction of the gun 1. Screw holes 16 and 17 are formed at right angles to the base supporting hole 9 and the base position adjusting elongated hole 11.

In the portable spot gun 1 provided with the base 8 having the above structure, FIG.
As shown in (a), the base supporting hole 9 of the base 8 is aligned with the screw hole 16 of the base mounting member 15, and the base position adjusting slot 11 is disposed at the upper right in the figure. When a part of the elongated hole 11 and the screw hole 17 of the base mounting member 15 are aligned with each other, the base 8 can be turned around the base supporting hole 9 and the projecting portion is formed. 12 and the hole 1 of the suspension fitting 7
The pivot 14 connected to 3 has a locus movable in the range indicated by a, and can be arbitrarily fixed to a desired position in the range of a1 in the axial direction of the gun and a2 in the direction perpendicular to the axis.
