Description

[Detailed description of the invention] In this invention, a vehicle-shaped guide guide 2 is pivotally supported on a machine frame 1, and a short cylindrical fitting guide protrusion 3 supplied to each guide guide 2' is slidable along the guide 2'. A mutually meshing bevel gear 5 is provided at one end of each rotary screw punch 4 supported along each guide 2', and a screw 6 screwed into each screw punch 4 is connected to the projection 3. The side gap of the supply short cylinder l is used to pivotally support the incoming air 8 in the central space of the vehicle-shaped guide guide 2, and the rotating shaft 9 of the floor plan 8 is provided as a common shaft inside the support shaft 10 of the guide guide 2. This invention relates to a rim welding side positioning device supported on a line.

The vehicle-like guide guide 2 has a plurality of pieces (
A hollow support shaft 10 is horizontally supported on a bearing 11 provided on the machine frame 1, and a rotating shaft 9 is mounted inside the support shaft 10 on a bearing 12. Supported through.

A pinion 13 is provided at one end of the rotating shaft 9.
A rack 14 that meshes with the cylinder 15 is provided on the cylinder 15.

The rotary shaft 9 has an air passage 16 inside, and is connected to a small air cylinder 17 provided in the radial direction at the tip of the same shaft 9. is provided, the floor plan 8 can enter the gap t by the force of the piston pressing spring 19, and the piston rod 18 can be operated with compressed air against the spring 19 to retreat the pawl 8 from the gap t. .

The screw 6 and the protrusion 3 are connected with a connecting fitting 20.
A cylinder 21 for holding down the outer surface of the short supply cylinder T is provided, but if the inner diameter of the cylinder I is expanded by being guided by the projection 3, the cylinder 21 may not be necessary.

22 and 23 in the figure are compressed air hoses, 24 is a guide inside the sliding box of the pawl 8, and 25 is a manual nozzle 1 provided on the screw punch 4.
26 is a short cylindrical receiving plate that can be raised and lowered, 27 is a cylinder for raising and lowering it, 28 is a hydraulic cylinder for adjusting the raising and lowering of the machine frame 1, 29 is a short cylindrical suppression supply plate, 30 is a cylinder for suppressing it, 31 is an undulating axis of the suppression supply plate 29;
2 is a cylinder for raising and lowering the undulation, 33 is a short cylindrical upper attachment/detachment device provided on the upright rotating shaft 34, 35 is a short cylindrical lower attachment/detachment device orthogonal to the same device 33, 36 is a welding device for the gap t, and 37 is a welding bulge. part cutting device, 38 is a short cylindrical supply conveyor, 3
8' is a discharge conveyor, 39 and 40 are short cylindrical 90 degree turning devices, and 4L42 is a short cylindrical transfer device.

Therefore, when a short cylinder I made of thin steel plate with an unwelded side gap t is placed on the receiving plate 26, 26 and the cylinder I is pressed in the direction of the arrow a in FIG. The inner diameter of the tube T expands as it is guided by the guide surface 3' of 3, and is fitted and supported by the protrusion 3.

Then, by operating the cylinder 17, the claw 8 is pressed against the inner surface of the cylinder I by the force of the spring 19, and the rotating shaft 9 is rotated, so that the claw 8 is pressed against the inner surface of the cylinder I.
When it is rotated one turn in the direction of the clock hands from the hour position, the floor plan 8 comes into pressure contact with the inner surface of the short cylinder I and rotates, and the force of the spring 19 closes the gap t.
enter.

After entering, the short cylinder 7 and the vehicle-shaped guide guide 2 are also attached to the support shaft 10.
When the pawl 8 is rotated around the clock and reaches the 12 o'clock position, it is stopped by the control device, and the gap t of the short cylinder I is stopped at the 12 o'clock position, and the gap t is positioned.

In this state, the upper and lower surfaces of both side edges of the gap t are held by the upper attachment/detachment device 33 and pulled in the direction opposite to the arrow a, separated from the protrusion 3, and transported around the upright rotation shaft 34 toward the gap welding device 36. can do.

If the inner diameter of the short cylinder γ changes in size, fit the manual handle into the corner 25 of the screw punch 4 and rotate the handle in one direction or the other.The screw punch 4 will rotate in the same direction and six The six screw punches 4 are simultaneously rotated in the same direction or in opposite directions through the meshing gears 5.

Due to this simultaneous rotation, the screws 6 screwed into each screw 4 slide in one direction or the opposite direction along each guide guide 2', and can be adapted to the difference in the inner diameter of the supply short cylinder 1.

The 12 o'clock position level of the gap t due to the difference in the inner diameter can be maintained at a constant level by operating the hydraulic cylinders 28 and 28 to adjust the vertical movement of the machine frame 1.

Since the present invention is configured as described above, when manufacturing a rim of an automobile by welding the gap of the short cylinder 70 having the unwelded side gap t, the position of the gap t is automatically set to the welding part position of the welding device 36. There is a practical advantage that it can be applied not only to the short cylinder I having a large and small inner diameter.
