Embodiment 1

[0022] Such as figure 1 , the deformable clamping device of the present invention is used to clamp various shapes of parts 4 to be clamped. The device comprises a soft clamping element 5 and a control device 1 . The soft clamping element 5 is used to cover the object 4 to be clamped. The control device 1 is arranged on the periphery of the soft clamping element 5 . The flexible clamping element 5 includes a cladding layer 2 and a filler 3 , and the filler 3 is filled in the cladding layer 2 . The filler 3 can flow, move or deform as the shape of the cladding layer 2 changes. The material of the cladding layer 2 is deformable soft material such as silica gel. The deformation of the soft clamping element 5 is by the flow, movement or deformation of the filler 3 .

[0023] In this embodiment, the control system 1 includes a pushing device, a magnetic field generating device and a magnetic field intensity control device. The driving device can be cylinder, hydraulic cylinder...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that the filling in the flexible clamping element 5 is electrorheological fluid, and the electrorheological fluid filling can be made to phase by changing the electric field strength of the flexible clamping element 5. Change into a solid-like form, thereby generating a clamping force on the part 4 to be clamped, and achieve the purpose of stably clamping the part 4 to be clamped.

[0031] Equally, the control system in the present embodiment comprises propulsion device, electric field generating device and electric field strength control device, and propulsion device can adopt air cylinder, hydraulic cylinder, electric push rod etc., and electric field generating device is connected on the propelling device and is connected with electric field strength control device. electrical connection. The coating 2 of the flexible clamping element 5 is attached to the electric field generating means. The pushing device p...

Abstract

The invention relates to a deformable clamping device, which comprises a soft clamping element and a control system. The control system is arranged on the periphery of the soft clamping element and is used for extruding the soft clamping element, so that the soft clamping element gets close to a piece to be clamped and is deformed along with a shape of the piece to be clamped so as to wrap the piece to be clamped. According to the device, through extruding the soft clamping element, the soft clamping element is in direct contact with the piece to be clamped and is deformed along with the shape of the piece to be clamped so as to wrap the piece to be clamped, and the phase change of a filler in the soft clamping element is controlled to convert into a solid state or a quasi-solid state from a liquid state, so that the soft clamping element can stably clamp the piece to be clamped, and the deformable clamping device belongs to flexible clamping, and has the characteristics of wide applicability and clamping stability.

Description

technical field [0001] The invention relates to a device for clamping special-shaped products, in particular to a deformable clamping device. Background technique [0002] With the advancement of science and technology, various products are constantly being introduced. Many products focus on appearance design in order to conform to ergonomics or appeal to visual effects. For example, a desktop speaker may be designed as a streamlined curved structure, or a trendy concept of a triangular shape. [0003] These special-shaped products must be clamped for assembly or inspection on the production line. However, when the appearance of the product changes frequently, the traditional clamping device cannot be applied to various products, and it is necessary to use manpower to move the product, or purchase a variety of different fixtures to clamp the product. This greatly reduces the efficiency or reliability of gripping these products. [0004] For large and complex parts, such ...
