Abstract

PURPOSE: To make welding easy and an object to be welded travel on table by setting the center part of table for fixed part and both sides for slide part and providing the groove of slide part arranged with exposed place due to moving away/traveling and a free caster placed in the groove free to elevate. CONSTITUTION: When an object to be welded placed on a table 21 is traveled, by actuating air cylinder, the object is traveled so that a slide part 23 moves away from a fixed part 22. Then, a groove 25 is exposed. When an universal caster supporting part in the groove is elevated, the caster is brought into contact with the object to be welded to lift. When the object to be welded is newly placed on the table 21, by elevating the free caster supporting part in the same way as before, the object to be welded is sent in on the universal caster. The spot welding is executed so that the slide part 23 is traveled to the fixed part side and is closed so as not to have clearance between the slide part 23 and fixed part 22, the object to be welded is set on the table 21 having no clearance.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spot gun table. More specifically, it relates to a spot gun table in which an object to be welded can slide on a table which is a spot surface (copper plate).

[0002]

2. Description of the Related Art Conventionally, in order to move an object to be welded on a table, several grooves, for example, two rows of concave grooves are provided on the surface of the table, and a plurality of free casters are arranged in each groove and are vertically movable. Tables for guns are known.
Then, when the object to be welded is slid, the universal caster is raised and the object to be welded is supported by the universal caster protruding from the table surface. Then, when the object to be welded is pressed, the universal caster is rotated and the object to be welded moves smoothly on the table surface. When the object to be welded is not moved, lower the free caster and store it in the groove. Then, at the time of spot welding, the universal caster is lowered to be housed in the groove, and the object to be welded is set on the table.

[0003]

However, in the conventional spot gun in which the object to be welded can move on the surface of the table, several recessed grooves are formed and the universal caster is always exposed. There was a problem that the part located above the groove could not be welded.

[0004]

Means for Solving the Problems

A fixed portion formed of a plate-shaped body installed in the central portion, a slide portion formed of a plate-shaped body installed adjacent to the fixed portion and moving toward and away from the fixed portion, and a separation of the slide portion from the fixed portion. A spot gun table characterized by comprising a groove provided at an exposed position by movement and a universal caster which is vertically movable within the groove,

[0006] and

[0007] A fixed portion formed of a plate-shaped body installed in the central portion, a slide portion formed of a plate-shaped body installed adjacent to the fixed portion and moving toward and away from the fixed portion, and a separation of the slide portion from the fixed portion. It is composed of a groove provided at an exposed position by movement and a free caster installed so as to be able to move up and down in the groove, and when the free caster is raised, one end side of the free caster is raised higher than the other end side. Spot gun table,

[0008]

When the object to be welded is loaded onto the table for installation, or when the object to be welded installed on the table is moved and unloaded, the slide portion is moved so as to be separated from the fixed portion. Then, the groove is exposed. Therefore, when the object to be welded is installed on the table, the universal caster in the groove is raised to feed the object to be welded to the table. Alternatively, when the object to be welded installed on the table is carried out, the universal caster is raised, and the universal caster comes into contact with the object to be lifted. When the object to be welded is pressed in the moving direction, the object to be welded moves on the table and is carried out. Alternatively, it is possible to rotate the object to be welded on a plane and change the direction because of the free caster.

When one end of the groove of the universal caster is raised higher than the other end of the universal caster when the universal caster is raised, it tilts toward the universal caster on the one end of the groove, so that the object to be welded can be moved in the inclined direction. .

Embodiments of the present invention will be described with reference to FIG. 1 showing a front view, FIG. 2 showing the same side view, FIG. 3 showing the same plan view, and FIG. 4 showing an enlarged view of the same portion.

Reference numeral 11 is a spot gun. Reference numeral 12 is a shaft that supports the spot gun 11, 13 is an arm that supports the shaft 12, and 14 is a column that supports the arm 13. A welding tip 15 is installed at the tip of the spot gun 11.

Reference numeral 21 is a table. Table 21
Is composed of a fixed part 22 made of a plate-like body installed in the central part of the table 21, and slide parts 23, 23 made of plate-like bodies installed adjacent to both sides of the fixed part 22. Two
4 is an air cylinder. The air cylinder 24 is
By the expansion and contraction operation, the slide portion 23 is moved toward and away from the fixed portion 22. A motor may be installed instead of the air cylinder 24 and the slide portion 23 may be moved. Reference numeral 31 is a guide, and the table 2 extends in the direction of the operator and the support 14 side.
1. Installed between the base.

Reference numerals 25 and 25 are grooves. The groove 25 and the groove 25 are provided at exposed portions by the movement of the slide portions 23, 23 away from the fixed portion 22. 26 is a universal caster support. The free caster support portion 26 is installed in the groove 25. The free caster support portion 26 is supported by the air cylinder 28 at both ends. Reference numeral 27 denotes a universal caster, which can rotate 360 degrees and is installed in large numbers on the universal caster support portion 26. Universal caster 27 is 360
Since the object to be welded is rotated once, the object to be welded installed on it can be moved in any direction, and the object to be welded can be rotated on the spot. The air cylinder 28 can be raised and lowered in two stages.

When moving the object to be welded installed on the table 21, the air cylinder 24 is operated to move the slide portion 23 so as to be separated from the fixed portion 22. Then, the groove 25 is exposed. Then, when the universal caster supporting portion 26 in the groove 25 is raised, the universal caster 27 comes into contact with the object to be welded and lifted. Table 21
When a new object to be welded is installed on the upper part, the universal caster support portion 26 is similarly lifted and then the object to be welded is fed onto the universal caster 27. When the object to be welded is pressed in the moving direction, the object to be welded moves on the table 21.

When the universal caster support portion 26 is raised, one end side of the universal caster support portion 26 is raised higher than the other end side. That is, when the air cylinder 28 supporting one end side of the universal caster support portion 26 is raised in two stages and the air cylinder 28 supporting the other end side thereof is raised by one stage, the universal caster support portion 26 is raised in two stages. Becomes higher and tilts, so that the workpiece can be moved in the tilted direction.

Free caster support 26 installed in two rows
One of the two is in two stages, and the other row is the free caster support portion 26.
When one is raised, the one free caster support 2
6 is positioned higher than the other free caster support portion 26, and the workpiece can be moved in the inclined direction.

When performing spot welding, the slide portion 23 is moved to the fixed portion 22 side, the slide portion 23 is fixed so that there is no gap between the fixed portion 22, and the object to be welded is placed on the table 21 with no gap. Let me do it.

[0018]

[Effects of the Invention] Therefore, according to the present invention, there is provided a spot gun table in which an object to be welded can be easily welded and which can be moved on the table.
