[0003] Metal barrels are generally made of steel plates. After the steel plates are rolled into circles, they are welded into shape, and the end caps are fixedly connected to the welded barrel body through curling, and finally sealed into finished products. Before the steel plates are rolled into circles and welded into shape, it is necessary to position the two ends to be welded of the steel plates. An upper pressing plate is required for positioning. The positioning mechanism in the prior art has low accuracy, which affects the qualification rate of the barrels. Now, an upper positioning device for a laser welding machine for making barrels is proposed to solve the problems in the prior art. Summary of the Utility Model

[0014] Compared with the prior art, the advantages of the present utility model are as follows:

[0015] (1) In the upper positioning device for a laser welding machine for making barrels in the present utility model, the first linear module improves the vertical lifting precision of the positioning plate, and the second linear module improves the overall horizontal movement of the first driving component, thereby improving the precision of positioning the to-be-welded end of the coiled steel plate by the positioning plate before welding, and thus improving the qualification rate of the barrels.

[0016] (2) In the present utility model, the positioning plate includes a first rectangular plate with a rectangular vertical section, a triangular plate with a triangular vertical section, and a second rectangular plate with a rectangular vertical section, which are arranged in sequence from top to bottom and have gradually decreasing widths.

Compared with a regular plate with a rectangular vertical section in the prior art, the positioning plate has greater strength. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0022] The following combines specific embodiments to further elaborate on the content of the present utility model:

[0023] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the utility model.

[0024] As Figures 1 - 3 shown, an upper positioning device for a laser welding machine for making barrels includes a vertically arranged positioning plate 1, a first driving component for driving the vertical lifting of the positioning plate 1, and a second driving component for driving the overall horizontal movement of the first driving component; the first driving component includes a first guiding component for guiding the vertical lifting of the positioning plate 1, and the second driving component includes a second guiding component for guiding the overall horizontal movement of the first driving component. The first driving component and the second driving component can be cylinders and electric cylinders. In this embodiment, both the first driving component and the second driving component are cylinders.

[0025] The positioning plate 1 is composed of multiple pieces arranged side by side in segments or the positioning plate 1 is a single integral plate. When the multiple positioning plates 1 are arranged side by side in segments, that is, each positioning plate 1 is equipped with a first cylinder 10 and a pair of first linear modules. The cylinder block of each first cylinder 10 is fixed on the vertical part of the adapter plate 9. The multiple first cylinders 10 act simultaneously. The advantage of this setting is that the force applied to the end to be welded of the coiled steel plate is more uniform and the positioning accuracy is higher.

[0026] The positioning plate 1 includes a first rectangular plate 2 with a rectangular cross-section arranged from top to bottom and gradually decreasing in width, a triangular plate 3 with a triangular cross-section, and a second rectangular plate 4 with a rectangular cross-section. The part of the positioning plate 1 that contacts the end to be welded of the coiled steel plate is the bottom surface of the second rectangular plate 4. One side of the first rectangular plate 2, the triangular plate 3, and the second rectangular plate 4 is in the same vertical plane. The triangular plate 3 and the second rectangular plate 4 together form an avoidance notch for other mechanisms to avoid interference. Since the strength of the positioning plate 1 is related to its width, if the width is too narrow, the force applied by the positioning plate 1 to the end to be welded of the coiled steel plate will be insufficient. Therefore, in this embodiment, the positioning plate 1 is designed to have a larger width at the top and a smaller width at the bottom. Compared with the positioning plate 1 in the prior art which is a regular plate with a rectangular cross-section, the positioning plate 1 has greater strength.

[0027] The second driving assembly is fixed on the fixed plate 5. The second driving part is the second cylinder 6, and the second guiding assembly is the second linear module. The second linear module includes a second linear guide rail 7 and a second slider 8 slidably fitted on the second linear guide rail 7. The first driving assembly is fixed on the adapter plate 9 with an L-shaped cross-section. The first driving part is the first cylinder 10, and the first guiding assembly is the first linear module. The first linear module includes a first linear guide rail 11 and a first slider 12 slidably fitted on the first linear guide rail 11. The cylinder block of the second cylinder 6 is fixed on the fixed plate 5, and the adapter plate 9 is fixed on the piston rod of the second cylinder 6. The second linear guide rail 7 is fixed on the fixed plate 5, and the second slider 8 is fixed on the horizontal part of the adapter plate 9. The cylinder block of the first cylinder 10 is fixed on the vertical part of the adapter plate 9. The positioning plate 1 is arranged on the piston rod of the first cylinder 10. The first linear guide rail 11 is fixed on the vertical part of the adapter plate 9, and the first slider 12 is fixed on the positioning plate 1. The number of the second cylinders 6 is two, and the number of the second linear modules is two. A pair of second linear modules are located on both sides of the two second cylinders 6. There is a pair of first linear modules on both sides of each first cylinder 10. The first linear module improves the vertical lifting accuracy of the positioning plate 1, and the second linear module improves the overall horizontal movement of the first driving assembly, thereby improving the positioning accuracy of the positioning plate 1 for the end to be welded of the coiled steel plate before welding.

[0028] The working principle of the upper positioning device of the laser welding machine for making barrels in the present utility model is as follows:Figure 3 Taking the orientation in [description] as an example, when the positioning plate 1 needs to act, the piston rod of the second cylinder 6 extends, pushing the whole first driving assembly to move horizontally to the left, thereby driving the positioning plate 1 to move horizontally to the left. Then, the piston rod of the first cylinder 10 extends, pushing the positioning plate 1 to descend and press on the end to be welded of the coiled steel plate. When resetting, the piston rod of the first cylinder 10 retracts first, and then the piston rod of the second cylinder 6 retracts.
