Description
Technical Field
[0001] The utility model relates to the technical field of grinding devices for casting, in particular to a grinding device for valve casting which is convenient to adjust. Background Art
[0002] Valves are control components in fluid conveying systems, with functions such as shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems, from the simplest shut-off valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. Valves 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. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, plastic valves and non-standard customized valve materials according to their materials. During the production process, the valve may have impurities such as bumps or burrs on the surface due to some reasons, and generally requires a grinding device to polish it to complete the surface cleanliness.
[0003] For example, a grinding device for valve castings with the announcement number CN216759212U includes: a workbench, a drive shaft, a grinding column and a grinding seat; the workbench is provided with a fixed seat; the fixed seat is rotatably connected to the driving shaft; the driving shaft is fixedly mounted with the grinding seat; the grinding seat is rotatably connected to the driven shaft; the driving shaft is fixedly mounted with bevel gear 1; the driven shaft passes through a side of the driving shaft and is fixedly mounted with bevel gear 2; the workbench is provided with a motor between bevel gear 1 and bevel gear 2; the motor is fixedly mounted with bevel gear 3; the bevel gear 3 is meshed with both bevel gear 1 and bevel gear 2.
[0004] The above-mentioned device is suitable for internal grinding of valve castings of different sizes by being able to adjust the position of the grinding column. However, it can be seen from the structure that its grinding device is not convenient in adjustment, and both the drive shaft and the grinding column need to be adjusted. In addition, the design of the device's clamping seat is relatively limited to valve grinding. When the valve needs to be polished on the outside, the clamping of the device will cause part of the valve surface to be blocked by the clamping seat, and the required grinding effect cannot be achieved.

[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. Compared with other valve casting grinding devices, this device can adjust the grinding device in direction or distance by designing multiple adjustment mechanisms on the components. In addition, considering that the main shape of the valve is cylindrical, the design of the rotating disk is used to drive the grinding end, and the sliding groove is used to achieve the grinding effect of valves within multiple radius ranges, so that the device can be used for more types of valves.

The main gear and the driven gear mesh with the rotating disk 7 installed at the lower end. The meshing of the two forms a two-sided support and fixing effect for the rotating disk 7 when it rotates.
[0023] Figure 2This is an oblique angle side view of the device. The main body is a moving block 3. The positive surface of the moving block 3 is actively assembled with a rotating disk 7, and the surface of the rotating disk 7 is provided with a sliding groove. At the same time, a sliding block is assembled inside the sliding groove, and the sliding block is engaged with the sliding groove. The upper end of the sliding block is installed with a grinding body, and a rotating shaft is inserted in the middle of the grinding body. At the same time, a grinding end head 8 is installed at the front end of the rotating shaft. A rotating machine 10 is installed on the surface of the grinding body, and a control button is installed on the surface of the rotating machine 10. The control button is used to operate the switch of the rotating machine 10, providing rotational power for the grinding body, driving the front rotating end head to grind the required grinding object, and the position of the grinding body can be adjusted by using the sliding groove to change the grinding radius, which is suitable for grinding multiple types of valves.
[0024] Figure 3 This is a small angle top view of the device. The main body is a working platform 2. The surface of the working platform 2 is installed with a clamping mechanism 9, and a clamping plate is inserted inside the clamping mechanism 9. At the same time, a sliding plate 13 is installed inside the clamping plate.
