Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for supplying an electrode tip for resistance welding.

[0002]

[Prior art]

 The electrode tip, which is used by fitting it to the tip of the resistance welding gun, wears its tip as the number of welding points increases. Therefore, the worn electrode tip is removed from the tip of the gun and replaced with a new electrode tip.

Conventionally, as a device for supplying a new electrode tip to the position of a tip of a resistance welding gun from which a worn electrode tip is removed, a spring or a hydraulically actuated plunger is used to sequentially feed and push the electrode tip. However, since the length of the spring or the stroke length of the plunger was required, the device inevitably became bulky, and it was difficult to secure the installation space at the welding site. Therefore, in order to improve the space efficiency at the welding site, a compact electrode tip supply device is desired.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems, and an object thereof is to provide an extremely compact electrode welding device for resistance welding that can improve the space efficiency at the welding site. To do.

[0005]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above object will be described with reference to the drawings corresponding to the embodiments. A partition 3 is vertically arranged in a supply container 1 having a compressed air connection port 2 at a head end thereof. The storage chambers 4 and 4 are divided into two parts in a split shape, and pressing blocks 5 and 5 which are pressed by compressed air are slidably fitted into the storage chambers 4 and 4, respectively, and the tip of the supply container 1 is formed. Electrode tips 8 and 8 are formed at both ends, and the electrode tips 6 and 6 inserted and arranged so as to face the storage chambers 4 and 4 are pressed toward the tip end by the pressing blocks 5 and 5. It is characterized by being configured as described above.

[0006]

[Action]

 When compressed air is press-fitted into the supply container 1 from the compressed air connection port 2 by the above means, the pressing blocks 5 and 5 in the storage chambers 4 and 4 in the supply container 1 respectively have their respective electrode chips 6 and 6. Is pressed toward the tip of the container.

Here, the tip ends of the pair of upper and lower sides of the resistance welding guns 9 and 9 are respectively attached to the respective electrode tip outlets 8 and 8 provided on the elastic members 7 and 7 at both end portions of the tip of the supply container 1. When inserted, the tip of each of the resistance welding guns 9, 9 is fitted with a fitting hole 10 formed in the back surface of the electrode tips 6, 6 located at the tips of the storage chambers 4, 4 in the supply container 1. 10, and the electrode chips 6, 6 are attached to the tip.

When the tips of the resistance welding guns 9, 9 are respectively retracted, the electrode chips 6, 6 attached to the tips are taken out of the supply container 1 through the electrode tip take-out ports 8, 8, respectively.

Then, the respective electrode tips 6, 6 remaining in the supply container 1 are sequentially extruded toward the tip of the container, stand by, and by repeating the above-described operation, the tip ends of the resistance welding guns 9, 9 are sequentially inserted. The electrode tips 6, 6 can be supplied to

[0010]

【Example】

 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described with reference to an illustrated embodiment. A hermetically-sealed supply container 1 has a compressed air connection port 2 at its head end and a partition 3 at a central position in the interior thereof. The storage chambers 4 and 4 are divided into two parts, and pressing blocks 5 and 5 that are pressed by compressed air are slidably fitted into the storage chambers 4 and 4, respectively. The pressing blocks 5 and 5 are formed with a concave curved surface on the front surface thereof so as to match the side peripheral surface of the electrode chip 6.

The supply container 1 is formed with elastic members 7 and 7 such as rubber plates at both ends of the tip, and the elastic members 7 and 7 are provided with electrode chip outlets 8 and 8 formed of holes or slits. In addition, the electrode chips 6 and 6 are inserted and arranged from the outlets 8 and 8 so as to face each other through the partition 3 in both storage chambers 4 and 4, so that the electrode chips 6 and 6 are stored in the storage chambers 4 and 4, respectively. Each of the electrode chips 6, 6 is configured to be pressed toward the tip of the container by the pressing blocks 5, 5.

In the figure, 9 and 9 are a pair of upper and lower resistance welding guns, and 10 is a fitting hole formed in the back surface of the electrode tip A so as to be fitted to the tip ends of the resistance welding guns 9 and 9. Show.
