Detailed Description

The invention will be further described by way of examples with reference to the accompanying drawings:

referring to fig. 1 and 2, a double-side processing and fixing structure of a large thin-wall plate on a grinding machine workbench is provided, and the grinding machine workbench 1 is provided with an electromagnet suction device 2. The large thin-wall plate 4 is divided into a first machined surface and a second machined surface, and double-side grinding is required. The large thin-walled sheet 4 is warped and deformed in a natural state.

The pre-processed surface is adhered to the grinding machine workbench 1 in a buckling deformation state through the adhesive fixing layer 3, and all buckling deformation areas of the large thin-wall plate 4 are filled with the adhesive fixing layer 3, so that the pre-processed surface can be ground in the buckling deformation state. The electromagnet holding device 2 is used for holding the workpiece when the front processing surface faces downwards so as to grind the rear processing surface. The machined surface is ground under the state of maintaining buckling deformation, and after the grinding is finished, the workpiece is turned over to enable the machined surface to face downwards. The viscose fixed layer 3 fills all the warping deformation areas with the viscose fixed layer 3, a good supporting effect can be achieved, the workpiece is fixed during grinding, the electromagnet suction device 2 is not needed to suck tightly during grinding of the machined surface firstly, and magnetic force can be loaded when the other surface of the workpiece is ground as long as the flatness of one surface of the workpiece is solved.

Preferably, the adhesive fixing layer 3 adopts hot melt adhesive or sealing silicon rubber; when hot melt adhesive is used, a hot melt adhesive heating device is provided to thermally melt the cured adhesive fixing layer 3. The curing time of the selected hot melt adhesive is preferably 5 to 8 minutes. When the sealing silicon rubber is adopted, the tapping hammer is arranged and used for tapping from the side surface of the large thin-wall plate 4 after the grinding of the machined surface is finished, so that the large thin-wall plate 4 can be taken down and turned over. The knocking hammer is preferably a rubber hammer, and may also be a metal rod or other knocking tools.

The grinding wheel is particularly suitable for large thin-wall plates 4 with the thickness less than or equal to 5.0mm and used for double-sided grinding processing on a grinding machine, such as a cover plate of a 70% low-floor gearbox.

The specific processing process when selecting the sealing silicon rubber is as follows:

(1) the method is characterized in that sealing silicon rubber (rubber used on site in the company) is approximately and uniformly coated on a workbench of a grinding machine, a workpiece is placed on the workbench, and the surface of the part to be ground is tapped by a rubber hammer or a copper bar so that the part presses the silicon rubber uniformly, and thus, the space for part deformation can be filled with the silicon rubber.

(2) The part is placed for a certain time and begins to be ground after the silicon rubber is solidified, and no magnetic force is needed to be loaded during grinding (because the deformation area of the part is filled with the silicon rubber, the influence of magnetic force loading grinding on the flatness is small, and the silicon rubber plays a good supporting role in the magnetic force and grinding stress on the part).

(3) The side surface of the workpiece is forced to move, the workpiece is taken down (the part surface is larger, the adhesive force of the adhesive is relatively larger, the workpiece is taken down relatively, and the part and the workbench are cleaned.

(4) The part is placed on a workbench of a grinding machine, and the other surface of the part is ground by loading magnetic force (as long as the flatness of one surface of the part is solved, the magnetic force can be loaded when the other surface of the part is ground).
