1 to 4 clearly illustrate only the main features in order to conceptually clearly understand the angle adjusting device of the welding torch with the ball joint of the present invention, as a result of which various modifications of the diagram are expected, The scope of the invention need not be limited by the particular shapes shown.

First, referring to FIG. 1, the angle adjusting device 100 of the welding torch having the illustrated ball joint includes a clamp 112 for fixing a torch at one end thereof and a ball rotating body 114 at the other end thereof. ) And a spherical socket groove 122 for partially inserting and embedding the ball rotator 114 so that an angle displacement of the welding arm 110 and the ball rotator 114 may be constrained, but the position is constrained. Ball rotating body fixing device 130 is provided to press and fix the ball rotating body 114 through the joint housing 120 for fixing the angle of the joint housing 120 and the ball rotating body (114). It consists of a configuration including.

First, the angle adjusting device 100 of the welding torch having the ball joint of the present invention is equipped with a torch T, so that the angle of the torch T can be flexibly flexed so as to achieve an optimal welding posture according to the welding target. At the same time, it is a device that can be fixed quickly and accurately to the adjusted angle.

To this end, the present embodiment includes a welding arm 110, a joint housing 120, and a ball rotator fixture 130, which are largely three configurations, each of which will be described in detail with reference to FIG. Let's do it.

2 is a view schematically showing a three-dimensional shape of the angle adjusting device of the welding torch having a ball joint according to an embodiment of the present invention.

As shown in FIG. 2, the welding arm 110 includes a clamp 112 that fixes the torch (T in FIG. 1) at one end thereof, and protrudes outward from the other end to extend outwardly. It is made in the form provided with).

The clamp 112 of the welding arm 110 should be able to be firmly fixed by mounting a torch (T in Fig. 1) of various diameters, for this purpose, both ends are divided into 1/2, each inside A groove corresponding to the diameter of the torch (T in FIG. 1) may be formed in a form of 1/2.

In order to firmly fix the torch (T in FIG. 1) mounted on the clamp 112, each of the divided ends may be formed to further include a separate fastening means (not shown) to be integrally fastened. .

The clamp 112 may be formed integrally with the welding arm 110 at the tip of the welding arm 110, but more preferably, the clamp 112 and the welding arm 110 is separated In other words, it is preferable that the clamp 112 has a form detachable from the tip of the welding arm 110.

According to the detachable and detachable form, the clamp 112 having various shapes, functions, and sizes may be interchangeably used at the tip of the welding arm 110, and thus may be useful for general use of the welding device. In addition, as another effect, when the endurance of the use of the clamp 112 is finished, there is an advantage that the new clamp 112 provided in the form of accessories can be replaced.

On the other hand, one end of the welding arm 110, that is, the front end is provided with a clamp 112 for fixing the torch (T), while the other end of the welding arm 110 is formed to protrude further outward Rotator 114 is formed.

Here, the ball rotator 114 corresponds to a constituent part forming an important feature of the present invention, the material may be a steel material with improved durability by securing a predetermined hardness and toughness, but this is only one example. However, the present invention need not be limited to the limitation of such materials. Therefore, various materials may be used.

The diameter of the ball rotating body 114 is proportional to the size of the spherical socket groove 122 inside the joint housing 120 to be described later, which is the total volume of the ball rotating body 114 in the spherical socket groove 122. This is because more than half of the parts are inserted and embedded in each other.

However, when the diameter of the ball rotating body 114 is the same as the size of the spherical socket groove 122, the frictional resistance is severe due to the contact between each other, so that the ball rotating body 114 embedded in the spherical socket groove 122 Since there may be a problem that can not be rotated flexibly, when considering a more flexible angle adjustment of the torch, it is preferable that the diameter of the ball rotating body 114 is formed to be slightly smaller than the diameter of the spherical socket groove 122.

A detailed description thereof will be made later when describing the necessity of forming a small play between the ball rotating body 114 and the spherical socket groove 122.

On the other hand, any one of the upper surface, the lower surface, the left side, the right side of the welding arm 110, the level (140 of FIG. 4) that can check the horizontal reference angle inclination of the welding arm 110 is further one. It may be provided.

Referring to Figure 4, it can be seen the appearance of the welding arm 110 is provided with such a level (140).

The level 140 is formed in the form of a small glass tube containing alcohol or a similar liquid and bubbles in a sealed inner space, and is a device that can check the angle of inclination on a horizontal basis through the movement of bubbles.

When the posture of the welding arm 110 is variously adjusted in conjunction with the free rotation of the ball rotator 114, whether the welding arm 110 is in a horizontal posture through the level 140, or further, the welding arm 110. ) The torch fixed to the vertical position can be confirmed.

Referring to FIG. 2 again, the joint housing 120 will be described.

The joint housing 120 is a member connected to the welding arm 110 provided with the ball rotating body 114 described above.

In other words, the connection between the joint housing 120 and the welding arm 110 is enabled by the joint housing 120 having the ball housing 114 protruding from the protruding rear end of the welding arm 110 embedded therein. The ball socket body 114 is inserted into the spherical socket groove 122.

Since the ball rotor 114 partially embedded in the spherical socket groove 122 should have a form capable of angular displacement and rotation for various degrees of freedom, the diameter of the spherical socket groove 122 is the diameter of the ball rotor 114. It is desirable to have a somewhat larger form than.

Due to the difference in diameter between the spherical socket groove 122 and the ball rotating body 114, a minute gap is formed in the parts facing each other.

3 is a view schematically showing the cross-sectional shape of the angle adjusting device of the welding torch having a ball joint according to an embodiment of the present invention. Referring to FIG. 3, a spherical socket groove 122 and a ball rotating body ( Due to the difference in diameter of the 114) it can be seen that the small clearance (C) formed in the parts facing each other.

Through the connection between the spherical socket groove 122 and the ball rotating body 114, in order to be able to adjust the angle more comfortably with respect to the joint housing 120, the welding arm 110 is the minute play (C) ) May be considered to be insufficient, so a lubricant for reducing frictional resistance may be filled and used on such a small clearance (C).

In addition, the lubricant is preferably supplied to the micro-gap phase even after the initial joint housing 120 and the welding arm 110 are fastened. For this purpose, the spherical socket groove 122 is provided from the outside of the joint housing 120. Until the fine needle injection hole can penetrate the injection needle can be formed.

The appearance of such a lubricant injection hole can be confirmed through Figure 4, as shown, the lubricant injection hole 126 is preferably formed on the upper side of the joint housing 120 as possible to prevent the outflow of the lubricant already filled. .

The joint housing 120 may be formed in the form of a joint that is permanently constrained with each other in a state in which it is coupled with the welding arm 110, but as a preferred embodiment, the replacement for the replacement of the welding arm 110 may be performed. In order to be detachable, the joint housing 120 may be formed in a form in which the tip 124 may be fastened and detached based on the spherical socket groove 122.

Therefore, even if wear, damage, breakage, or the like occurs in any one of the joint housing 120 and the welding arm 110, it is possible to replace with new parts, in addition, the spherical socket groove 122 And maintenance on the ball rotating body 114 can be facilitated.

The ball rotator fixture 130 is fastened to be released and released through a fastening hole (125 in FIG. 2) formed at one side of the tip 124 of the joint housing 120 to fix the angle of the ball rotator 114. As a means, as the end is firmly pressed against the outer circumferential surface of the ball rotating body 114 as it rotates in the fastening direction, the angular displacement of the ball rotating body 114 is fixed.

As shown in FIG. 3, when the torch angle is fixed, the ball rotator fixture 130 penetrates one side of the tip 124 of the joint housing 120 and enters the outer circumferential surface of the ball rotator 114. To take the form of pressing the ball rotating body 114, on the contrary, in the case of adjusting the torch angle, the ball is retracted to the outside of the tip 124 of the joint housing 120 to release the pressure of the ball rotating body 114.

According to the illustrated embodiment, this ball rotator fixture 130 appears to be a fixing bolt, but this is only an example, the present invention need not be limited thereto. Therefore, other fixing means may be used by changing various embodiments.

In addition, according to the illustrated embodiment, the ball rotator fixture 130 is made of a single configuration, which is intended to conceptually clearly explain the function of the ball rotator fixture 130, a plurality of ball rotator fixture The form having 130 is also included in the scope of the present invention.

However, the increase in the number of the ball rotator fixture 130 may also act as a means that the time required to fix the torch at a set angle can be increased, the size of the ball rotator 114 in each embodiment and It may be desirable to appropriately adjust the number depending on the material and the welding object and method.
