Grinding device for machining butterfly valve for multifunctional ship

Abstract

The invention discloses a grinding device for machining a butterfly valve for a multifunctional ship. The grinding device comprises a base, two groups of reinforcing plates, a positioning assembly, grinding assemblies, a dish plate and a protective assembly, wherein the two groups of reinforcing plates are installed on the two sides of the upper surface of the base in parallel, and the positioning assembly is installed on one side of the top end of each reinforcing plate; the grinding assemblies are symmetrically installed on one side of the positioning assembly and connected with the reinforcing plates, the dish plate is assembled on the positioning assembly, and the protective assembly is installed below the positioning assembly and the grinding assemblies. A first air cylinder is electrically controlled, two groups of clamping plates are linked to get close to each other and get away from each other between positioning pieces, so that dish plates of different sizes can be rapidly positioned and fixed; in the subsequent grinding process, a driving motor drives two groups of linkage columns and the dish plate to rotate in the positioning pieces, and under cooperation with the grinding assembly, the dish plate can be automatically ground, so that the circumferential end face of the dish plate can be quickly and precisely ground, and the situation that the traditional grinding effect of the circumferential end face of the dish plate is poor is avoided.

Description

technical field [0001] The invention relates to the related technical field of butterfly valve processing equipment, in particular to a grinding device for processing multifunctional marine butterfly valves. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switching control of low-pressure pipeline medium. After the production is completed, the circumferential end face of the built-in disc needs to be polished to ensure the accuracy of the subsequent opening and closing inside the butterfly valve. Therefore, a grinding device is required to be used in conjunction with it. However, the existing butterfly valve is grinding the internal disc during production. , the overall operation is inconvenient, and the discs of different sizes cannot be quickly positioned and subsequently driven, and the full-range driving of the grinding work cannot be satisfied, which affects the grinding accuracy...

Problems solved by technology

[0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switching control of low-pressure pipeline medium. After the production is completed, the circumferential end face of the built-in disc needs to be polished to ensure the accuracy of the subsequent opening and closing inside the butterfly valve. Therefore, a grinding device is required to be used in conjunction with it. However, the existing butterfly valve is grinding the internal disc during production. The overall operation is inconvenient, and the discs of different sizes cannot be quickly positioned and subsequently driven, and the full-range driving of the grinding work cannot be satisfied, which affects the grinding accuracy of the discs.

[0003] The existing technology has the following disadvantages: in the production of the existing butterfly valve, when grinding the internal disc, the overall operation is inconvenient. The range drive affects the grinding accuracy of the disc. At the same time, the existing grinding device does not have an external protection function, and does not block and protect the grinding process, which is prone to waste debris splashing
