Problems solved by technology

However, because the shape of the workpiece surface is too complicated, the traditional operation is to absorb the dial indicator on the spindle of the machine tool, and then level it for alignment. In this process, it is often necessary to level it first, and then adjust multiple or individual supports Height, then leveling detection, and then adjust the height of the support, so repeated operations back and forth many times, making the shape-finding very laborious, and the work efficiency is particularly low

Embodiment 1

[0048] Such as figure 1 and figure 2 As shown, the present invention provides a magneto-rheological support device applied to complex curved surface structures, and its structure includes:

[0049] The base 6 is used to achieve detachable connection with the installation platform or the machine tool workbench. The base 6 can preferably be a magnetic base, which can be easily and quickly installed and disassembled from the installation platform.

[0050] The lifting assembly is fixed above the base 6, and the lifting assembly is used to realize the height adjustment of the device.

[0051] Specifically, the lifting component can be realized by a four-linkage lifting platform, or it can be realized by the following specific structure, which can realize folding shrinkage and lifting, and the structure includes:

[0052] A plurality of support plates 2 are vertically arranged above the base 6 , one end of the support plates 2 is fixed to the upper surface of the base 6 , and th...

Embodiment 2

[0079] As a further optimization scheme based on Embodiment 1, in order to change the position of the magnetic force control assembly, so as to change the position of the support point for the workpiece, and adapt to the clamping requirements of workpieces of different sizes and shapes, the structure of the present invention has been improved as follows:

[0080] A plurality of linear guide rails 21 electrically connected to the peripheral power supply are provided. The linear guide rails 21 are arranged in a ring and are evenly distributed. The extension lines of the length direction of the plurality of linear guide rails 21 intersect at the center of the ring. Each linear guide rail 21 and One motor one 19 corresponds, the fixed body of the linear guide rail 21 is fixed to the inner bottom surface of the cavity structure, and the moving body of the linear guide rail 21 is fixed to the motor one 19 .

[0081] When the linear guide rail starts, it can drive the motor one 19 to ...

Abstract

The invention belongs to the technical field of machining, and relates to a magneto-rheological supporting device applied to complex curved surface structures, including a base; On the top of the component, a groove is opened on the top surface, and a cavity structure is opened directly below the groove; the magnetorheological fluid is filled in the groove and communicated with the storage tank of the peripheral device through a pipeline; the double-acting pump is set in the On the pipeline, it is used to realize the suction of the magnetorheological fluid, so that the amount of the magnetorheological fluid in the groove changes; the magnetic force control component is arranged in the cavity structure, and the magnitude and direction of the magnetic force are adjustable. Realize the control of the path and deformation of the magnetorheological fluid, adapt to the curved surface shape of the workpiece, and realize the support for the workpiece; the pressing component, at least one, is detachably connected to the top surface of the workbench and distributed in the groove around. The invention has a reliable structure and improves the form-finding efficiency of complex curved surfaces.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a magnetorheological support device applied to complex curved surface structures. Background technique [0002] In mechanical processing, some thin-walled workpieces with complex surface shapes are often encountered. The stable and reliable clamping of these workpieces is a difficult problem in processing. When clamping, it is necessary to find the shape of the workpiece to facilitate the workpiece. further processing. However, because the shape of the workpiece surface is too complicated, the traditional operation is to absorb the dial indicator on the spindle of the machine tool, and then level it for alignment. In this process, it is often necessary to level it first, and then adjust multiple or individual supports Height, and then leveling detection, and then adjust the height of the support, so repeated operations back and forth many times, so that...
