Thin-wall sphere supporting device

Abstract

The invention discloses a thin-wall sphere supporting device. The device comprises a machine base and a driving device; the machine base comprises a top plate, a base plate, vertical rods, a fixed hinge support and a movable hinge support; the top plate and the base plate are arranged in parallel and fixedly connected through the four vertical rods, reducing mechanisms are arranged between the adjacent vertical rods, and the fixed hinge support is arranged at the bottom of the top plate; the fixed hinged support is used for being connected with the fixed ends of the reducing mechanisms, and the movable hinged support is used for being connected with the telescopic ends of the reducing mechanisms; and the output end of the driving device is connected with the movable hinged support, and the driving device rotates to drive the movable hinged support to move up and down, so that the reducing mechanisms are held tightly or withdrawn. According to the variable-diameter thin-wall sphere supporting device, the multiple sets of reducing mechanisms are adopted for clamping or supporting a sphere, an accurate spherical surface is defined by supporting blocks, deformation of the supported sphere cannot be caused, and the thin-wall sphere or a low-rigidity spherical object is well protected.

Description

technical field [0001] The invention relates to a thin-walled spheroid supporting device, which belongs to the technical field of tools. Background technique [0002] In view of the fact that the fixed cylindrical foam stabilizer in the foam stabilizer of the film winding device cannot be stretched, etc., and there is no ideal foam stabilizer in the industry, Liaocheng Huasu Industry Co., Ltd. designed a telescopic ring foam stabilizer, application number 201110053399.6 , the end-to-end connection of the telescoping ring structure forms a circular ring. However, according to theoretical analysis and animation simulation, this design cannot realize telescoping, has serious technical defects, and cannot be used in practice. Therefore, designing a sphere that can dynamically adjust the diameter of the sphere to adapt to the change of the supported bubble can more accurately stabilize the bubble of the blown film; the device can also be used to grab other thin-walled low-rigidit...

[0002] In view of the fact that the fixed cylindrical foam stabilizer in the foam stabilizer of the film winding device cannot be stretched, etc., and there is no ideal foam stabilizer in the industry, Liaocheng Huasu Industry Co., Ltd. designed a telescopic ring foam stabilizer, application number 201110053399.6 , the end-to-end connection of the telescopic ring structure forms a circular ring. However, according to theoretical analysis and animation simulation, this design cannot achieve telescopic expansion and has serious technical defects, so it cannot be used in practice.
