Problems solved by technology

[0004] The purpose of the present invention is to design a method that can prolong freezing and solidification in view of the problems that the existing bearing devices made of cast iron have too fast melting speed and short life, and the bearing devices made of non-metallic materials have poor rigidity and poor polishing efficiency. The service life of the abrasive polishing pad can guarantee a certain rigidity of the frozen solidified abrasive polishing pad bearing device. At the same time, a polishing pad with both rigidity and uniform heat dissipation is designed to meet the requirements of the frozen solidified abrasive polishing process

Embodiment 1

[0029] Such as figure 1 , 2 , 3, 4 shown.

[0030] A frozen solidified abrasive polishing pad bearing device aims at making the frozen solidified abrasive polishing disc bearing device have a certain rigidity and uniformly controlling the melting rate of the frozen solidified abrasive polishing disc. The carrying device is mainly composed of a stiffness providing layer 1 and a heat insulating layer 2. The greater the difference in thermal conductivity between the stiffness providing layer 1 and the heat insulating layer 2, the better, and the diameters of the stiffness providing layer 1 and the heat insulating layer 2 are the same, such as figure 1 As shown, the thermal insulation layer 2 is above the stiffness-providing layer 1, and the rigidity-providing layer 1 and the thermal insulation layer 2 can be connected through a screw structure, or can be connected in a form similar to a dovetail groove structure, such as figure 2 shown. The overall shape of the stiffness-prov...

Embodiment 2

[0033] Such as figure 1 shown.

[0034] A kind of frozen solidified abrasive polishing pad with heat insulation layer, it is mainly made up of carrying device and polishing disk 3 of embodiment one, as figure 1 According to the method, the carrying device is mainly composed of a rigidity providing layer 1 made of cast iron and a heat insulating layer 2 made of polytetrafluoroethylene. The heat insulating layer 2 is located between the rigidity providing layer 1 and the polishing disc 3, and the heat insulating layer 2 One side of the heat insulating layer 2 is connected with the rigidity providing layer 1, and the other side of the heat insulating layer 2 is frozen and connected with the frozen solidified abrasive layer forming the polishing disc 3. layer infiltrated so as to connect the thermal insulation layer 2 and the polishing disc 3 by freezing a plurality of annular dovetail grooves 4 with an equal difference in diameter ( image 3 ) or evenly and symmetrically arrang...

example 1

[0037] The melting thickness curve of the ice plate adopting the traditional cast iron plate and the polishing pad carrying device of the present invention is as follows Figure 4 shown. It can be seen that due to the heat exchange between the traditional cast iron plate and the surrounding environment, the melting rate of the ice plate is very fast, and the melting thickness reaches 11.5mm in 60 minutes, while the freezing thickness of the general frozen solid abrasive polishing plate is about 15mm. Therefore, basically the service life of the frozen solidified abrasive polishing disc is about 60 minutes. However, after adopting the polishing pad carrying device of the present invention, due to the existence of the heat insulating layer, the melting thickness of the polishing pad is only 6 mm after 60 minutes. The service life of the frozen solidified abrasive polishing disc is increased by more than 100%.

[0038] At the same time, by adopting the invented polishing pad ca...

Description

technical field [0001] The invention relates to a precision machining device, in particular to a bearing device for a frozen-fixed abrasive polishing pad and the polishing pad, in particular to a device capable of providing sufficient rigidity for the frozen-fixed abrasive polishing pad and enabling freezing and solidification of the polishing pad. The utility model relates to a frozen solidified abrasive polishing pad carrying device and a polishing pad thereof whose melting rate of the frozen solidified abrasive polishing pad is uniformly controlled. Background technique [0002] The frozen solidified abrasive polishing disc uses ice as a binding agent to prepare the polishing abrasive into a colloidal freeze, which belongs to the low-temperature polishing technology. In a low temperature environment, it can reduce residual stress, microscopic cracks and surface damage on the processed surface. Due to the special properties of frozen solidified abrasives, it is not possib...
