In general, welding using a welding machine is to join and melt a welding rod and a base material by heat generated by a current (about 6000 ° C.) between the welding rod and the base material, and a base material to be welded and a ground wire connecting them are required. Reaction electrode is composed of a welding electrode holder for generating an arc and a welding electrode and the welding electrode to connect the welding electrode and the welding electrode holder.

In order to weld with the above equipment, the base metal to be welded must first be grounded. The equipment used for this is a ground clamp.

In general, the ground clamp 1 'used to connect the ground wire to the base material during welding has a c-shaped clamp main body 15' having legs at both sides as shown in FIG. 5, and the clamp main body ( 15 ') a crimp terminal 32' to which a ground wire fastening piece 31 'which is fixed by an ordinary bolt, a ground wire crimped using a crimp lug terminal is connected, and the crimp terminal 32' ) Is fixed to the upper portion of the other side of the clamp main body 15 ') and constitutes a ground wire connecting portion 2' made of a crimp terminal fixing bolt 33 'for connecting the ground wire and the clamp main body 15'. The clamping bolt 19 'is penetrated in the direction of one leg in the middle of the other leg portion of the'), and the base material 30 is positioned between the legs, and then the clamping bolt 19 'is tightened to tighten the base material ( 30, the clamp main body 15 'is fixed.

However, the conventional ground clamp as described above should use several types of ground clamps according to the thickness of the base material, and when the ground wire is connected to the ground clamp, many preparations such as crimping lug terminals, crimping lugs clamps, and crimping terminal fixing bolts are provided. Not only is it necessary, but it takes a lot of work time and the crimping lug is not complete.Therefore, there was a problem that the ground wire and the ground clamp were disconnected when welding to the base material. The breakage of the ground wire clamping part of the ground wire and the part fixed to the ground clamp is peeled off, and the clamping bolt is naturally disconnected from the strong wind due to shaking of the ground wire in strong winds or the impact of surroundings. There was a problem that caused.

The present invention is to solve the problems as described above is equipped with a clamp body that can be separated and coupled to perform a variety of functions irrespective of the size of the base material, using a ground wire case to replace the existing crimp lug It can be connected in a short time with less tools than the method used, and the elastic rubber tube is inserted between the grounding wire holder and the grounding wire to prevent the grounding wire from being easily peeled off or disconnected due to shaking or twisting during long-term use. The purpose is to provide an improved universal ground clamp for welding in which the clamping bolts do not loosen naturally even in strong winds or shaking using nuts.

To achieve this purpose, the universal grounding clamp of the present invention is composed of a metal grounding wire connecting part and a clamp body, and the grounding wire connecting part is provided with a grounding wire case, but one side of the grounding wire is inserted into the grounding wire. The holder is to be inserted through the clamp body, the clamp body is composed of a fixed clamp and a movable clamp fixed to the bottom of the ground wire case, the fixed clamp is provided with a vertical anchor to the clamp fastening bolt through the center portion One side of the movable clamp support is fixedly attached to the center of the upper part in the horizontal direction, and the clamp support jaw is attached to the upper left and right sides of the vertical fixing stand, and the movable clamp release prevention plate is fixedly attached to the upper end of the movable clamp support. Union to clamp support jaw The movable clamp is prevented from escaping toward the upper side, and the movable clamp is fixed side by side with the other side of the adjuster spaced apart at regular intervals on both sides of the upper end of the vertically movable movable support, and at the center of the movable clamp support. There is a feature of the present invention that a plurality of clamp support jaw insertion grooves are formed at predetermined intervals at which the clamp clamp is inserted into the movable clamp support insertion grooves to be fitted.

Covered in and around the ground wire case (3), the elastic rubber tube 14 is inserted between the ground wire (8) and the ground wire holder (5) and the ground core wire (10) is completely connected to the ground wire case (3) Ground core fixing bolts 13a and 13b to ground core fixing holes 14a and 14b to be fixed. And fasten to the ground line holder fixing hole (7) to the ground line holder fixing hole (7) so that the ground line holder (5) does not move or deviate.

The ground wire holder 5 extends 10-30 mm out of the ground wire case 3, and the rubber tube 14 extends 10-30 mm out of the ground wire holder 5 to surround the ground wire 8, and thus the ground wire 8 ) Is to prevent the coating (9) from being peeled off or disconnected by shaking or twisting when used for a long period of time in contact with the ground clamp.

The clamp body 15 is composed of a fixed clamp 16 and a movable clamp 25 that can be separated and coupled as shown in Figures 1 to 3 and 5, the fixed clamp 16 is clamped in the center portion A vertical fixing stand 17 is formed of a rectangular parallelepiped into which the tightening bolt 19 is fastened. The vertical fixing stand 17 has one side of the movable clamp support 18 of a rectangular parallelepiped in the horizontal direction at the center of the upper end. The clamp support jaw 21a, 21b is protruded from the upper left and right sides of the vertical fixing stand 17, but the movable clamp release preventing plate 22 is integrally formed at the upper end of the movable clamp support 18. It is fixed to support the grounding wire case (3) is fixed to the upper portion while supporting the movable clamp (25) coupled to the clamp support jaw (21a) (21b) to prevent the separation to the upper side.

In addition, the movable clamp release prevention plate 22 has a ground line case support jaw 23 protrudingly formed at the center of one side thereof, thereby easily tilting the adjusters 27a and 27b into the spaces on both sides of the ground line case support jaw 23. While supporting the one side of the ground wire case (3).

That is, the upper portion of the movable clamp release preventing plate 22 and the ground line case support jaw 23 is fixedly attached to the ground line case 3 at the top as shown in FIG.

The movable clamp 25 is fixed side by side fixed side by side with the other side of the control member 27a (27b) made of a rectangular parallelepiped on both sides of the upper end of the vertical movement support (26) vertically spaced, A movable clamp support insertion groove 29 is formed in which the clamp support 18 is fitted in a concave-convex manner, and the clamp support jaws 21a and 21b are inserted into the lower portions of the adjusters 27a and 27b. A plurality of clamp support jaw insertion grooves 28a and 28b are formed at a predetermined interval so that the clamp support jaw 21a and 21b of the fixed clamp 16 is the clamp support jaw insertion groove 28a of the movable clamp 25. 5, the movable clamp 25 is inserted inclined horizontally to be inserted into the 28b, and the clamping jaw insertion grooves 28a and 28b are inserted and fastened according to the thickness of the base material 30. It is.

The clamp tightening bolt 19 has a long rod-shaped clamp tightening bolt rotating rod 24 through the head portion to tighten the clamp tightening bolt 19 more easily and tighten the clamping tightening bolt 19 to ground.
