Abstract
Description
Technical Field
[0001] The utility model relates to a precision manufacturing technology and use equipment, in particular to a valve plate electrophoresis shielding fixture. Background Art
[0002] like Figure 1 The valve plate 100 shown in the figure needs to be electrophoretically treated on the periphery of the valve plate 100, and the valve plate surface 101 requires complete grinding treatment. The current process is: rough grinding - polishing and deburring - electrophoresis - fine grinding. The product is electrophoretically processed after rough grinding, and then the electrophoretic paint on the end face of the valve plate 100 is ground off with fine grinding equipment.
[0003] During fine grinding, the valve plate 100 is fixed on the jig through the valve plate assembly hole 102 to ensure that the coating along the periphery of the valve plate 100 is not damaged. This results in some high-efficiency through-type end face grinders being unable to be used for the production of such parts. Only single-end face grinders can be used in the production of valve plate parts, with very low production efficiency and relatively high fine grinding costs.
[0004] Therefore, it is necessary to provide a valve plate electrophoresis shielding fixture to solve the above problems. Utility Model Content
[0005] The utility model aims to provide a valve plate electrophoresis shielding jig.
[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0007] A valve plate electrophoresis shielding jig comprises a lower fixed plate, on which a plurality of positioning posts are arranged, and one of the valve plate or the isolation gasket is loaded in a precisely positioned manner through the positioning posts to form a high-precision positioning loading structure, and the other of the valve plate or the isolation gasket is again isolated through the high-precision positioning loading structure to form a gasket isolation gasket combination structure, and then loaded in turn through the high-precision positioning loading structure and the gasket isolation gasket combination structure to the required number of electrophoresis operations; and an upper pressure plate is arranged corresponding to the positioning post to form a valve plate electrophoresis shielding jig that only performs electrophoresis around the valve plate.
[0008] Furthermore, the isolation gasket is composed of a high temperature resistant silicone pad.
[0009] Furthermore, the diameter of the isolation gasket is 0.3 mm to 0.8 mm larger than the valve plate.
[0010] Furthermore, the number of positioning columns is 2-5.
[0011] Furthermore, the lower fixing plate and the upper pressure plate are provided with a polished light-resistant layer on the corresponding valve plate loading surface.
[0012] Furthermore, the diameter of the visible layer is ground to be consistent with the valve plate and in contact with the high temperature resistant shielding gasket to prevent the accumulation of electrophoretic paint after electrophoresis.
[0013] Furthermore, a lifting ring is provided on the upper pressure plate.
[0014] Compared with the prior art, the utility model uses a valve plate electrophoresis shielding fixture that only performs electrophoresis on the periphery of the valve plate. There is no need to subsequently remove the electrophoretic paint from the pad surface, and there is no problem of electrophoretic damage. High-efficiency double-end surface grinding equipment can be used to greatly improve production efficiency and reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS
