Clamping and rotating device for stainless steel insulation cups

Abstract

The invention aims at providing a clamping and rotating device reliable in clamping, capable of rotating at a high speed and used for stainless steel insulation cups. The clamping and rotating devicecomprises at least three clamping sticks with stick cores located in the vertical planes. Each clamping stick horizontally moves in the radial direction, cylinders defined by the stick cores of each set of corresponding clamping sticks share the core all the time during horizontal movement, and the clamping sticks are driven by drive units to rotate around the cylinder cores of the cylinders. According to outer diameters of the different stainless steel insulation cups, the clamping sticks can horizontally move in the radial direction to clamp the stainless steel insulation cups, all the clamping sticks simultaneously and synchronously move, the cylinders defined by the stick cores of each set of corresponding clamping sticks share the core all the time, and therefore it is ensured that the axis cores of the stainless steel insulation cups clamped on the clamping sticks are definite and stable; and the drive units drive the clamping sticks to rotate around the cylinder cores of the cylinders, and in other words, the rotation centers of the stainless steel insulation cups on the clamping sticks are definite and stable.

Description

technical field [0001] The invention relates to the technical field of clamping stainless steel thermos cups, in particular to a clamping and rotating device for stainless steel thermos cups. Background technique [0002] In the prior art, the spraying of the stainless steel thermos cup is mainly external spraying, and after a long time of use, the stainless steel surface of the thermos cup will still be stained or attached to the foreign matter in the cup due to personal habits and it is not easy to clean. Therefore, it is necessary to spray the inside of the stainless steel thermos cup. Before the internal spraying, the outside of the thermos cup must first be clamped, and in order to ensure the uniformity of the spraying, the clamp must be able to drive the thermos cup to rotate at high speed during the spraying process. The traditional clamping and rotating device has a three-jaw chuck. In the process of rotating processing, the clamping force of the three-jaw chuck is t...

AI Technical Summary

Problems solved by technology

The traditional clamping and rotating device has a three-jaw chuck. In the process of rotating processing, the clamping force of the three-jaw chuck is too large to cause damage to the outer wall of the thermos cup. If the clamping force is too small, it is easy to loosen, causing Processing error, so the three-jaw chuck is not suitable for the clamping rotation of the thermos cup
