Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a support device for a sheet metal work, and a positioning pin provided on a jig for supporting the sheet metal work has a positioning hole for the flexible sheet metal work. Insert and decide the position,
A small article provided with a projection such as a screw rod is supplied to a supply table, and the projection is inserted into a fitting hole provided in the supply table so that the axis intersects with the axis of the positioning pin. After welding to the work to be manufactured, the projections of the small articles can be smoothly removed from the supply base.

(Prior Art) A positioning pin for a flexible sheet metal work is inserted into a positioning pin provided on a jig for supporting a sheet metal work to determine the position, and a small article having a protrusion such as a screw rod is supplied. It is supplied to a table and the projection is inserted into a fitting hole provided in the supply table so that the axis intersects with the axis of the positioning pin, and the small article is welded to the sheet metal work, and then the projection of the small article. A structure for removing an object from a supply table is already known. However, conventionally, as shown in FIG. 7, there is no problem in supplying an insertion hole b which is provided on the supply table a and into which the protrusion c of the small article wa is inserted, and it is possible to push up the sheet metal work w in the arrow direction. Since the relief hole has an inverted trapezoidal shape that does not cause any trouble, it has a drawback that the supply of the small article wa having the protrusion c to the supply table a is not stable.

(Problems to be Solved by the Invention and Purpose of the Invention) In view of the above, the present invention stabilizes the supply of the small articles wa to the supply base, and the movement of the sheet metal work w in the push-up direction parallel to the positioning pin, The problem to be solved is to make it possible without causing resistance, and it is an object of the invention.

(Means for Solving Problems) The present invention has a specific configuration that meets the above-mentioned object,
Insert the positioning hole of flexible sheet metal work such as fuel tank band into the positioning pin provided on the jig to determine the position, and supply small articles with protrusions such as screw rods to the supply table. The projection is inserted into a fitting hole provided in a supply table so that the axis intersects with the axis of the positioning pin, and the small article is welded to the sheet metal work,
In a device that pushes up and removes the sheet metal work in the axial direction of the positioning pin, a rotary body having a fitting hole for inserting the protrusion into the supply table for small articles is pivotally supported so as to be movable back, When the work is pushed up in the axial direction of the positioning pin, the work made of sheet metal is bent, and accordingly, the rotating body is rotated until the fitting hole is parallel to the push-up direction. This relates to a work support device.

A preferred embodiment of the present invention will be described in the next section.

(Embodiment) In the embodiment of FIGS. 1 to 6, in order to support the fuel tank, a positioning hole 2 is provided at one end and a ring 3 is provided at the other end, and the bending is made to match the lower surface and the side surface of the vehicle fuel tank. The fuel tank band 1 subjected to the above is used as a sheet metal work w, and a small article wa having a protrusion 33 formed of a screw rod is fixed to the lower surface thereof by welding. The sheet metal work w is not rigid but has flexibility.

As shown in FIG. 1, the jig 10 for supplying the work w is provided with a stand 13 projecting a vertical positioning pin 14 on a support column 12 projecting on one side of a mounting table 11 and an upper side on the other side. A support plate 15 whose part is inclined toward the column 12 is attached, and the guide surface 18 and the bearing surface (electrode) of the ring 3 at the other end of the sheet-metal work w are mounted on the upper support plate 16 via an insulator. Surface 19), and a cylinder 21 on a cylinder base 20 fixed on the installation base 11 between the support column 12 and the support plate 15 and a cylinder 21.
And guide cylinders 23 on both sides thereof are provided, a lift plate 24 that moves in the axial direction of the positioning pin 14 is connected to the cylinder rod 22, and a sliding rod 25 that fits into the guide cylinder 23 is attached.
Several projecting pieces 26 for fitting the sheet metal work w on the lift plate 24
And a supply table 28 for small articles wa is provided on a block 27 which is mounted on the support plate 15 and is parallel to the relevant portion of the sheet metal work w. As shown in FIGS. 5 to 6, the small article wa has welding ears 31, 31 parallel to the sheet metal work w at both ends, but the bottom piece 32 formed by bending is used as the sheet metal work w. On the other hand, the protrusions 33 are tilted in the opposite direction and project from the bottom piece 32 by a screw rod having an axis line that is not parallel to the axis line of the positioning pin 14. As shown in FIG. 3, the bottom piece 32 of the small article wa is welded to the supply table 28 by the welding ears 31, 31.
Is a groove-shaped bearing surface 34 that bears parallel to the lower surface of the sheet metal work w.
Is provided, and a groove portion 35 which is further lowered is formed in the center of the bearing surface 34, and a rotating body 36 in a direction traversing the groove bearing surface 34 is supported so as not to project on the bearing surface 34. Then, the protrusion 33 of the small article wa appearing on the upper surface of the groove-shaped portion 35 is fitted almost intimately with the end portion of the L-shaped arm 37 provided at one end thereof being in contact with the balance weight 38 and the receiving plate 39. An insertion hole 40 is provided (see FIG. 4).

(Operation) As shown in FIG. 4, the present invention inserts the projection 33 of the small article wa into the insertion hole 40 of the rotary member 36 provided on the supply base 28 so that the axis of the small article wa intersects with the axis of the positioning pin 14. After supplying the same to the supply table 28, the positioning hole 2 of the sheet metal work w is fitted into the positioning pin 14 of the jig 10, the ring 3 at the other end is supported by the protruding piece 17, and the intermediate portion of the lift plate 24. The protrusion 26 is fitted into and supported by the upper end of the protrusion 26, and the welding ear 31 of the small article wa is welded to the sheet metal work w by the spot welding electrode (see FIG. 4). 14
The work w made of sheet metal is pushed up by extending in the axial direction.

At that time, the work w made of sheet metal is bent due to its flexibility, and accordingly, the rotating body 36 provided on the supply base 28 is rotated by the protrusion 33 and the fitting hole 40 is moved to the insertion hole 40 as shown in FIG. It becomes parallel to the thrust direction of the sheet metal work w. As a result, as shown in FIG. 6, the protrusion 33 completely comes out, and after the protrusion 33 comes out, the protrusion 33 automatically returns to the original angle by the balance weight and rotates.

(Effect) The present invention determines the position by inserting a positioning hole of a flexible sheet metal work such as a band of a fuel tank into a positioning pin provided on a jig, and a small article provided with a projection such as a screw rod. The article is supplied to the supply table, the projection is inserted into a fitting hole provided in the supply table so that the axis intersects with the axis of the positioning pin, and the small article is welded to the sheet metal work, In a device that pushes up a work made of sheet metal in the axial direction of the positioning pin to remove it, a supply base for small articles wa
Rotating body 36 having a fitting hole 40 into which the above-mentioned protrusion 33 is inserted in 28
When the sheet metal work w is pushed up in the axial direction of the positioning pin 14, the sheet metal work w bends, and the fitting hole 40 becomes parallel to the pushing direction. Since the rotating body 36 rotates until it becomes a small article
The protrusion 33 of wa can be removed and removed smoothly by rotating the rotating body 36 so that the rotating body 36 can return.
