[0033] The present invention will be further described in conjunction with the following embodiments.

[0034] Example 1.

[0035] like Figs. 1-3 As shown, a fixture for bending sheet metal parts includes a support frame 1, on which a rotating fixture mechanism 2 is mounted. Two ends of the rotating fixture mechanism 2 are engaged with sheet metal parts 3. The bottom of the sheet metal parts 3 is abutted against a bending die 4, which is the lower die of the bending equipment. The bending die 4 is a set of dies with different bending angles, which need to be selected according to the bending angle of the sheet metal parts 3 in actual production.

[0036] The bending die 4 abuts against the middle of the rotating tooling mechanism 2. The upper die of the bending equipment presses down on the sheet metal part. The bottom of the sheet metal part contacts the bending die 4 and the rotating tooling mechanism 2 to bend the sheet metal part into shape. The bending equipment is existing technology and will not be described in detail here. The upper die of the bending equipment consists of multiple dies with different bending angles, and the upper die of the bending equipment and the bending die 4 are dies that cooperate with each other.

[0037] During the production process of the sheet metal body 3, the rotating tooling mechanism 2 installed on the support frame 1 can be used to position and clamp sheet metal bodies 3 of different sizes and bending angles.

[0038] like Figs. 1-3As shown, the rotating tooling mechanism 2 includes two positioning support plates 5. The two ends of the bending die 4 abut against the two positioning support plates 5. The two positioning support plates 5 are movably connected. Any one of the positioning support plates 5 is axially connected to a motor A 6. The motor A 6 is fixedly installed on the support frame 1. The support frame 1 is movably connected to the other positioning support plate 5 through a bearing. Each positioning support plate 5 is equipped with a clamping assembly 7. The two clamping assemblies 7 are respectively clamped to both ends of the sheet metal body 3.

[0039] A positioning support plate 5 is driven to rotate by a motor A 6. The rotating positioning support plate 5 acts as the driving component, and the other positioning support plate 5 acts as the driven component. During the production process of the sheet metal body 3, by controlling the bending angle between the two positioning support plates 5 and cooperating with the clamping component 7, sheet metal body 3 of different sizes and bending angles can be positioned and clamped.

The motor A 6 is axially driven and installed at the end of one positioning support plate 5 where the gear ring 8 is installed. The end of the other positioning support plate 5 where the gear ring 8 is installed is movably connected to the support frame 1 through a bearing. The positioning support plate 5 includes a telescopic plate body 15. A telescopic spring B16 is installed inside the telescopic plate body 15 for elastically adjusting the length of the positioning support plate 5, so as to adapt to the bending and forming of sheet metal parts 3 of different sizes.

[0041] A positioning support plate 5 is driven to rotate by motor A6. The rotating positioning support plate 5 drives the gear ring 8 to rotate. The rotating gear ring 8 is the driving member, and the other gear ring 8 is the driven member. The transmission connection between the two gear rings 8 can control the rotation angle of the two positioning support plates 5 in a coordinated manner. At the same time, the two positioning support plates 5 are always vertically symmetrical, which is convenient for measuring the bending angle.

[0042] like Figs. 1-3 As shown, the clamping assembly 7 includes a slide rail 9, which is mounted on a positioning support plate 5. A base 10 is slidably mounted on the slide rail 9, and a support rod 11 is hinged to the base 10. A telescopic spring A12 is installed between the bottom of the support rod 11 and the base 10 to facilitate adjustment of the clamping angle for sheet metal parts 3 of different sizes. A buckle 13 is slidably mounted on the support rod 11, and a positioning block 14 is installed between the buckle 13 and the support rod 11. The positioning block 14 positions the buckle 13 slidably mounted on the support rod 11, so that the buckle 13 clamps and positions the sheet metal parts 3 of different sizes, achieving a better clamping effect on the sheet metal parts 3.

[0043] This utility model includes a rotating tooling mechanism 2, with sheet metal body 3 clamped at both ends of the rotating tooling mechanism 2. A bending die 4 abuts against the bottom of the sheet metal body 3. The bending die 4 abuts against the rotating tooling mechanism 2. During the production process of the sheet metal body 3, by controlling the bending angle between the two positioning support plates 5 and cooperating with the clamping assembly 7, sheet metal body 3 of different sizes and bending angles can be positioned and clamped. A telescopic spring A12 is installed between the bottom of the support rod 11 and the base 10 to facilitate adjustment of the clamping angle of sheet metal body 3 of different sizes. The positioning block 14 positions the buckle 13 that slides on the support rod 11, so that the buckle 13 clamps and positions the sheet metal body 3 of different sizes, achieving a better clamping effect on the sheet metal body 3.
