Technical Field

[0001] The utility model relates to the technical field of butterfly valve processing equipment, and more specifically, to a burr grinding device for butterfly valve processing. Background Art

[0002] A butterfly valve, also called a flap valve, is a simple regulating valve that can be used for the on-off control of low-pressure pipeline media. A butterfly valve is a valve with a disc as the closing part, which rotates around the valve axis to open and close. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting off and throttling in pipelines.

[0003] When butterfly valves are produced, burrs will appear on the edges of the butterfly valves. Therefore, in order to ensure the quality, burr grinding operations are required. However, the existing burr grinding devices mainly perform grinding through fixed grinding heads, which cannot adapt to butterfly valves of different sizes. At the same time, the operability is poor, thereby reducing the deburring efficiency of the butterfly valve. Utility Model Content

[0023] Lifting legs 2 are fixedly installed at both ends of the upper part of the processing table 1. The upper telescopic ends of the two lifting legs 2 are respectively fixedly connected to the two ends of the bottom of the linear guide 3. The lifting legs 2 can be a hydraulic cylinder or an electric push rod in the prior art.

A circular groove 11 is opened in the middle of the upper surface of the processing table 1, and the turntable 5 is located in the circular groove 11. A motor 7 for driving the turntable 5 to rotate is installed inside the processing table 1, and the clamping mechanism 6 is slidably installed on the turntable 5.

[0025] In this embodiment, the openings on both sides of the grinding block 4 are arc-shaped, and the inner side walls of the openings are provided with a grinding layer, which is a frosted layer in the prior art.

[0026] Furthermore, in order to facilitate the smooth insertion of the inner ring of the valve body into the outer sides of the two pressing blocks 61 , in this embodiment, an inclined surface is provided on the outer sides of the upper ends of the pressing blocks 61 .

[0027] Furthermore, in order to prevent the pressing block 61 from damaging the butterfly valve body and to increase the friction between the pressing block 61 and the valve body, in this embodiment, a rubber sheet 62 is fixedly installed on the outer side of the pressing block 61 at the lower end of the inclined surface.
