ELECTRODE HOLDER

TECHNICAL FIELD

The present invention relates to an electrode holder having at least one body for use in welding processes, at least one first housing on said body, at least one grabber which can at least partially enter into said first housing, at least one jaw provided on said grabber, at least one coupling housing provided in the vicinity of said jaw.

PRIOR ART

Welding is a method used in joining the same or similar alloyed parts, materials or metals whose melting temperatures are close to each other. One of the primary welding methods is the electrical arc supply. The electric arc supply is the process of melting metal and solidifiying metal after the welding process is completed by using or by not using additional wire. In electrical arc supply applications; welding machine, chassis, electrode, electrode holder and welding protective equipment are used.

An electrode holder compresses the electrode between two jaws and melts the electrode by means of electrical current. Moreover, there are grooves for providing connection of electrode on jaws at different angles. Today the most practical usage of electrode holder is as such. However, during the use of such electrode holder, some problems are faced. The most frequent of them is that the jaws of the holders are worn in time. The worn jaws lead to malfunctioning of the electrode holder. The most important reasons of the wearing are that the electrode short-circuits depending on the contact formed by the electrode during use and overheating of the electrode during melting and the incompliancy of the grooves of the jaws with the electrode diameter, and subjecting of the electrode holder to impact during use. In such cases, the jaws are deformed and become useless.

As a result, because of all of the abovementioned problems, an improvement is required in the related technical field. BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to an electrode holder, for eliminating the above mentioned disadvantages and for bringing new advantages to the related technical field.

An object of the present invention is to provide an electrode holder with long lifetime and for use in welding processes.

In order to realize the abovementioned object and the objects which are to be deducted from the detailed description below, the present invention is an electrode holder having at least one body for use in welding processes, at least one first housing on said body, at least one grabber which can at least partially enter into said first housing, at least one jaw provided on said grabber, at least one coupling housing provided in the vicinity of said jaw. Accordingly, the subject matter electrode holder comprises at least one arm where the grabber is connected from one end in a removable manner for providing movement of the grabber inside the housing, at least one spring configured to continuously draw said arm into the first housing, at least one formed part configured to narrow the coupling housing. Thus, the grabbing of the electrode is made practical and can be changed easily without losing time in case the grabber is worn.

In a possible embodiment of the present invention, at least one of the first housing and the grabber has a cross-section which narrows towards the side where the spring is provided. Thus, the jaws are drawn towards the housing by the spring and the electrode is compressed inside the coupling housing.

In a possible embodiment of the present invention, the arm is connected to the jaw from one side and connected to at least one button from the other side. Thus, the movement of the arm by the user is made ergonomic.

In a possible embodiment of the present invention, the body has at least one step at the inner part thereof. Thus, the arm can linearly move inside the body and it functions as a base for the spring.

In a possible embodiment of the present invention, said spring is positioned between said button and said step. Thus, the spring continuously draws the grabber towards the first housing, and the separation of the electrode from the grabber during use is prevented. In a possible embodiment of the present invention, the spring is positioned around the arm. Thus, during linear movement of the arm inside the body, the undesired compression of the spring is prevented during linear movement and long usage lifetime is provided.

In a possible embodiment of the present invention, the spring has a conical shape. Thus, when the button is pressed, the spring is compressed more and the coupling housing is separated more.

In a possible embodiment of the present invention, the arm and the grabber are connected in a removable manner by means of at least one grabber connection and arm connection. Thus, the grabber can be easily changed in case it is deformed.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter electrode holder (10) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

In Figure 1 , a representative cross-sectional view of the subject matter electrode holder (10) is given. Accordingly, the subject matter electrode holder (10) has at least one body (30) for holding the electrode used in the welding process and at least one rod (20) for providing guiding of said body (30) by the user. Moreover, the electrode holder (10) comprises at least one sheath (70) which at least partially closes the rod (20) and the body (30).

In Figure 2, a representative cross-sectional view of said sheath (70) which at least partially encircles the subject matter electrode holder (10) is given. Accordingly, the sheath (70) has insulation characteristic and has at least one handle (71 ) thereon which encircles the rod (20). Said handle (71 ) provides handling of the electrode holder (10) by the operator in an ergonomic manner.

In Figure 3, a representative cross-sectional view of the rod (20) and the body (30) in the subject matter electrode holder (10) is given. Accordingly, the rod (20) and the body (30) are made of conductive material. The electrical current desired to flow through the rod (20) and through the body (30) is provided by means of at least one electric connection (21 ) positioned at one side of the rod (20). In a possible embodiment of the present invention, said electric connection (21 ) is connected to the rod (20) and to the electrical cable in a conductive manner.

The body (30) has a cylindrical hollow shape and essentially has at least one step (60) in the middle thereof. At least one first housing (40) is positioned at one side of said step (60) and at least one second housing (50) is positioned at the other side of said step (60). At least one grabber (41 ) is positioned for providing grabbing of the welding electrode inside said first housing (40). Said grabber (41 ) can move linearly along the body (30) by means of at least one arm (51 ) being connected. Said arm (51 ) and said grabber (41 ) are connected to each other in a removable manner by means of at least one arm connection (52) and at least one grabber connection (42). The arm (51 ) essentially extends longitudinally at the inner part of the body (30) and one side thereof remains inside the first housing (40) and the other side thereof remains inside the second housing (50). The arm (51 ) is also connected to at least one button (53) on the second housing (50) side. Between said button (53) and said step (60), at least one spring (54) is positioned which is wrapped around the arm (51 ). Said spring (54) is stopped onto the step (60) from one side and exerts continuous pressure onto the button (53). In a preferred embodiment of the present invention, the spring (54) has a diameter which narrows from the step (60) towards the button (53). By means of this, the spring (54) is compressed more and the arm (51 ) enters into the first housing (40). When the operator desires to move the grabber (41 ), he/she presses the button (53). When the operator stops exerting pressure to the button (53), the button (53) returns back by means of the spring (54).

The grabber (41 ) has at least one jaw (43) for grabbing the welding electrode. At least one coupling housing (45) is positioned in the vicinity of said jaw (43). In a preferred embodiment of the present invention, there are at least four jaws (43) and they are positioned such that there is essentially equal angle in between in the inner side of the first housing (40). Said coupling housing (45) is preferably positioned between the jaws (43). The coupling housing (45) can receive the electrode at least partially. Moreover, there is at least one each formed parts (44) on the jaws (43). Said formed part (44) provides the jaw (43) to narrow towards the side which faces the spring (54). In the alternative embodiments of the present invention, the formed part (44) can also be provided on the first housing (40). The formed parts (44) are stopped onto the inner side of the first housing (40) during the linear movement of the grabber (41 ) and provides bending of the jaws (43) towards the coupling housing (45) and provides compressing and holding of the electrode. In the opposite case, the formed part (44) loosens in the first housing (40) and widens the coupling housing (45) and releases the electrode. Said grabber connection (42) and said arm connection (52), which provide connection of the grabber (41 ) and of the arm (51 ), preferably have gears and these can be separated from each other as desired by the operator.

In an exemplary usage of the present invention, the user presses the button (53) and the jaws (43) can widen the coupling housing (45). Meanwhile, the user changes electrode and ends the pressure exerted to the button (53). By means of the spring (54), the arm (51 ) draws the jaws (43) back towards the first housing (40). The jaws (43) narrow the coupling housing (45) by means of the movement of said formed part (44) with respect to the first housing (40). As pluralities of jaws (43) are provided on the grabber (41 ), the electrode is prevented from short-circuiting, and the usage lifetime of the grabber (41 ) is increased. However, in long-duration usage, it can be deformed as the grabber (41 ) is damaged. In this case, the grabber connection (42) and the arm connection (52) are separated from each other and the grabber (41 ) can be changed. Since the grabber (41 ) is changeable, the lifetime of the electrode holder (10) extends, and grabber (41 ) can be preferred according to different electrode diameters.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
