Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a welding surface used when performing a steel welding operation.

[0002]

[Prior art]

 Conventional welding surfaces are integrated, and when performing work, hold the welding surface with one hand, or operate the welding surface attached to the belt fixed to the head up and down while Although it is a work mode in which the holder is operated by hand, it does not cause much trouble if the welding object is a large inanimate object, but if the welding object is small, the welding object is It requires moving, twisting, turning angles, re-setting many times, and having auxiliary workers. When working alone, it is often troublesome to support the welding target with one hand, operate the holder with the other hand, and not to use the welding surface, which causes eye burns and suffers for several days. , Anyone involved in welding work should have experienced it many times. Although it is an inevitable work-related accident, it is naturally left as a labor practice in the industry.

[0003]

[Problems to be solved by the device]

 This plan frees the hands that were previously operating the welding surface from the operation of the welding surface, and enables the work of setting and fixing the welding target, while it is naturally left as a labor practice and is not used for welding work. It solves the problem of eye burns experienced by workers and saves labor for assistant workers.

[0004]

[Means for Solving the Problems]

 (B) As shown in Fig. 2, a hollow pipe (3) (4) acting as a hinge is provided on one side of the frame (1) into which the light shielding glass (2) is fitted, and the inner wire of the guided wire (6) is A terminal (5) for fixing the tip is provided. (B) As shown in Fig. 1, adjust the tip of the viewing window of the welding surface (7) so that it will engage with the inside of the frame (1) of the light-shielding glass to prevent light from entering from the front and to protect the light-shielding glass. The hollow hinge pipe for hinge (8) (9) (10) (11) is installed in a position that works well with the hollow hive pipe for hinge (3) (4) of the frame (1) of the glass, and the frame (1) of light-shielding glass Engage with each other, set the pin (12) to the inner diameter of the hollow pipe (3) (4) (8) (9) (10) (11), and the frame (1) of the light-shielding glass works smoothly with the hinge. To do so. (C) Make a hole in the welding surface (7) at a position matching the wire mounting terminal (5) of the frame (1), fit the tip of the guide of the guided wire (6), and attach the guide to the welding surface (7). Fasten inside with fasteners (21) (22). (D) Provided on the upper and lower sides of the guide pipe (13) are blades (14) and (15) for attaching to the inside of the welding surface (7), and on the surface opposite to the blade mounting surface, the same point on the circumference of the pipe is vertically grooved. Cut it open and attach it to the lower part inside the welding surface (7) as a guide pipe (13). (E) A hollow pipe is used as the slide shaft (16) that moves up and down in the guide pipe (13), and a plate (17) that is operated by placing a chin on the shaft to open and close the frame (1) is attached to the slide pipe. Pass the inner wire of the guided wire (6) through the shaft (16). (F) Insert the coil spring (18) between the upper end of the guide of the guided wire (6) and the wire attachment terminal (5), and pass the upper end of the inner wire of the guided wire (6) through the tip of the wire. Tighten the retaining nut (19) on the outside of the wire mounting terminal (5). (G) After covering the welding surface (7) on the head and checking that the detachable belt (23) fits on the head, close the mouth and engage the teeth, and fill the lower jaw with the plate (17) fully. Move the slide shaft (16) to a touching position, and at the lower end of the slide shaft (16), attach the inner wire tip lock nut (20) of the guided wire (6) to the inner wire of the guided wire (6). Tighten. (H) When working on the welding surface (7), the welding surface (7) escapes to the front, the plate (17) that opens and closes by placing the chin off the chin, and opening and closing the light-shielding glass (2). To prevent inability to operate, turn the necklace (24) to the back of the neck and attach both ends of the necklace (24) to the lower part of the welding surface (7) matching the position of the necklace. In order to make it easy to put on and take off, connect the middle of the necklace (24) with a cloth zipper (25).

[0005]

[Action]

 Since this plan is constructed as described above, when using it, put the welding surface (7) on your head and turn the necklace (24) to the back of your neck to secure it with the cloth zipper (25). By moving the chin up and down, the light-shielding glass (2) fitted in the frame (1) can be freely opened and closed without using hands.

[0006]

【Example】

 For the implementation of the present invention, after putting on the welding surface (7) on the head and confirming that the detachable belt (23) fits on the head, attach the neck string (24) and lower the chin to remove the frame (1 ), The light-shielding glass (2) opens, the field of view opens, and when the jaw is raised, the light-shielding glass (2) closes together with the frame (1) due to the expanding action of the coil spring (18), and the flash light generated by the welding work is It can be prevented.

[0007]

[Effect of device]

 When the welding surface of the present invention is attached, the hand is not necessary for operating the welding surface, so that one hand can operate the welding holder and the other hand is free so that the work piece can be supported. Become. When using a conventional welding surface, when it is necessary to work with both hands, it is possible to avoid the pain from eye burns, which was caused by the inability to support the welding surface, and the conventional Since the auxiliary worker who used to be required is no longer needed, human labor can be saved.
