Description

Technical Field

[0001] The utility model relates to the field of supporting tooling, in particular to a supporting tooling for punching metal plates. Background Art

[0002] Sheet metal refers to a plate-like material made of metal and is commonly used in industry, construction, and manufacturing.

[0003] In the prior art, metal plates are common items in life, which play a role in protection and decoration. In order to facilitate the use of metal plates, holes are usually punched on the metal plates and used with bolts to facilitate the installation and disassembly of the metal plates.

[0004] However, in order to ensure that the metal plate does not deviate when punching, it is particularly important to clamp and fix the metal plate. The traditional method of clamping the metal plate is to clamp and fix it on the supporting workbench with a claw. However, when clamping an irregularly shaped metal plate, the claw cannot find enough force-bearing area on the metal plate, making the clamping unstable and the metal plate easily detached during punching.

It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] For example 1, please refer to Figures 1-8 The utility model provides a technical solution: a supporting tool for punching holes in metal sheets, a screw 2 is movably inserted into the interior of the supporting workbench 1, and the screw 2 serves as a device for driving the installation platform 3 to move. A mounting platform 3 is provided on the surface of the supporting workbench 1, and a slider 16 is fixed to the bottom surface of the installation platform 3. A threaded hole 15 is provided inside the slider 16, and a first inner groove 11 is provided inside the installation platform 3. Due to the threaded fit and the slider 16 being restricted by the groove 8 and unable to rotate, the rotation of the screw 2 will drive the installation platform 3 to move along the groove 8 toward the metal sheet through the slider 16. A first spring 10 is provided on the inner wall of the first inner groove 11. Two groups of first springs 10 will squeeze the first baffle 17, so that the first sector block 4 can automatically reset when not in use.

[0029] A first baffle 17 is fixed to the curved surface of the first sector block 4, a second inner groove 20 is opened inside the first sector block 4, and a second spring 23 is provided on the inner wall of the second inner groove 20. When the second baffle 28 rotates, it will squeeze the second spring 23. When the second spring 23 is squeezed, it will exert a reaction force on the inner wall of the second inner groove 20, thereby driving the first sector block 4 to rotate around the first rotation axis 14 in the first sector groove 12. A second sector block 5 is movably provided on the inner wall of the second inner groove 20, and a second baffle 28 is fixed to the curved surface of the second sector block 5. A gasket 25 is fixed on the plane of the second sector block 5. The surface of the gasket 25 is rough, which can have sufficient friction with the metal sheet to prevent the metal sheet from loosening when clamped.

[0030] On the basis of Example 1, in order to enable the support workbench 1 to clamp irregularly shaped metal plates, a groove 8 and a through hole 6 are opened inside the support workbench 1, the through hole 6 and the groove 8 are connected, and an annular groove 7 is opened on the inner wall of the through hole 6 near the port, and an annular block 9 is fixed on the outer surface of the screw 2.

[0031] The annular block 9 corresponds to and is clamped in the annular groove 7 and is movably connected. The slider 16 corresponds to and is clamped in the groove 8 and is movably connected. The screw rod 2 corresponds to and is clamped in the threaded hole 15.

[0032] A first limiting block 13 is fixed to the inner wall of the first inner groove 11, a first fan-shaped groove 12 is opened on the plane of the mounting platform 3, a first rotating shaft 14 is fixed to the bottom surface of the mounting platform 3, a first limiting groove 18 is opened on the surface of the first baffle 17, and a first positioning hole 24 is opened on the axis center of the bottom surface of the first fan-shaped block 4.

[0033] The first limiting block 13 corresponds to and is clamped with the first limiting groove 18 and is movably connected. The first sector groove 12 corresponds to and is clamped with the first sector block 4 and is movably connected. The first rotating shaft 14 corresponds to and is clamped with the first positioning hole 24 and is movably connected.

[0034] A second limiting block 21 is fixed to the inner wall of the second inner groove 20, a second sector-shaped groove 19 is opened on the plane of the first sector-shaped block 4, a second rotating shaft 22 is fixed to the bottom surface of the first sector-shaped block 4, a second limiting groove 27 is opened on the surface of the second baffle 28, and a second positioning hole 26 is opened on the bottom axis of the second sector-shaped block 5.

[0035] The second limiting block 21 corresponds to and is clamped with the second limiting groove 27 and is movably connected. The second sector groove 19 corresponds to and is clamped with the second sector block 5 and is movably connected. The second rotating shaft 22 corresponds to and is clamped with the second positioning hole 26 and is movably connected.

[0036] In actual use, the mounting platform 3 is provided with two groups, one of which is interspersed with screws 2 and is movably connected on the supporting workbench 1, and the other group is fixedly installed on the supporting workbench 1. First, the metal sheet is placed between the two mounting platforms 3, and then the screw 2 is rotated. Due to the threaded fit and the slider 16 is restricted by the groove 8 and cannot rotate, the rotation of the screw 2 will drive the mounting platform 3 to move along the groove 8 toward the metal sheet through the slider 16. The first to contact the metal sheet is the second sector block 5. Due to the irregular shape of the metal sheet, the second sector block 5 will rotate around the second rotation axis 22 in the second sector groove 19, so that the gasket 25 can contact as much area of ​​the metal sheet as possible. When the rotation amplitude of the second sector groove 5 is not enough to allow the gasket to When the sheet 25 contacts a metal sheet with a sufficient area, the rotation of the second sector groove 5 will drive the second baffle 28 to rotate inside the second inner groove 20, and the second baffle 28 will squeeze the second spring 23 when it rotates. When the second spring 23 is squeezed, it will exert a reaction force on the inner wall of the second inner groove 20, thereby driving the first sector block 4 to rotate around the first rotation axis 14 in the first sector groove 12. The rotation of the first sector block 4 increases the rotation amplitude of the second sector block 5, so that the gasket 25 fixed on the second sector block 5 can contact a metal sheet with a sufficient area, so that the gasket 25 has sufficient clamping force points on the metal sheet, thereby realizing that the support workbench 1 can clamp irregularly shaped metal sheets.
