Description

Technical Field

[0001] The utility model relates to the technical field of welding turning platforms, in particular to a tool fixture turning platform. Background Art

[0002] After the fixture is installed on the flip platform, the flip platform can drive the fixture to rotate, causing the workpiece installed on the fixture to rotate a certain angle. The purpose of this is to allow the workpiece to rotate a preset angle under the drive of the flip platform, making it easier for the welding robot to weld.

[0003] There is usually only one driving device on the welding platform to drive the fixture to rotate. Figure 2 When the span is long, if the drive device is only connected to one end of the frame, the two ends of the frame will inevitably be subjected to uneven forces, which may easily lead to stress concentration problems.

[0004] For example, the document "CN205614277U" proposes a fixture turning platform. When in use, a servo motor drives the fixture mounting frame to rotate through a worm gear reducer. When the horizontal span of the fixture mounting frame is large, one end of the fixture is driven by the servo motor and is bound to be twisted, resulting in uneven force on both ends.

[0005] Or the document number "CN210849900U" proposes a tooling fixture flipping platform, which, when in use, drives the U-shaped mounting block to rotate by a servo motor. This solution also has the problem of uneven force on the end away from the drive motor when the span between the two U-shaped mounting blocks is large.

[0006] In summary, we propose a fixture flipping platform to solve the above technical problems. Utility Model Content

The two connecting plates 7 are connected to each other, and the connecting plates 7 and the connecting seat 8 and the support frame 10 are fastened and installed by bolts, which makes it convenient to disassemble the support frame 10.

[0031] The present application also installs a driving device in the middle of the base 4. The specific structure of the driving device includes a gear box 1 arranged in the middle of the top of the base 4. The two output shafts of the gear box 1 are respectively connected to the first drive shaft 3, and the input shaft of the gear box 1 is connected to the driving motor 2.

[0032] The first drive shaft 3 is parallel to the mounting shaft 16, and its ends are rotatably connected to the bracket 15.

The drive device synchronously drives the two first drive shafts 3 to rotate, and the two first drive shafts 3 synchronously drive the mounting shafts 16 through the transmission mechanism. Therefore, when the mounting shafts 16 rotate, they can also drive the support frame 10 to rotate, allowing the fixture on the support frame 10 to rotate by a preset angle.

[0033] The above transmission mechanism includes three modes:

[0034] 1. As Figure 2 As shown, the transmission mechanism includes a second drive shaft 13 rotatably mounted on the side surfaces of two brackets 15, and at least two supports 12 are rotatably mounted on the second drive shaft 13.
