Description

Technical Field

[0001] This utility model belongs to the field of valve processing technology, and specifically relates to a valve flange grinding device for valve processing. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media. During valve manufacturing, the valve flange surface requires deburring and grinding.

[0003] Traditional grinding methods mostly rely on manual grinding, which is not only inefficient and of poor quality, but also cannot grind the end face and side of valve flanges simultaneously, increasing grinding time, reducing grinding efficiency and the practicality of the device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a valve flange grinding device for valve processing. This solves the problems mentioned in the background art, where traditional grinding methods are mostly done manually, which is not only inefficient and of low quality, but also cannot grind the end face and side face of the valve flange at the same time, which increases grinding time, reduces grinding efficiency and reduces the practicality of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a valve flange grinding device for valve processing, comprising a grinding box, a fixed base fixedly connected to one side inside the grinding box, a telescopic rod fixedly connected to one side of the fixed base in a circular shape, a clamping plate fixedly connected to one end of the telescopic rod, a screw symmetrically rotatably connected inside the grinding box, a moving plate threadedly connected to the outside of the screw, a second motor fixedly connected to the top of the moving plate, a rotating shaft fixedly connected to the output end of the second motor, a first grinding disc fixedly connected to the bottom of the rotating shaft, cylinders symmetrically arranged on one side of the first grinding disc, a moving block fixedly connected to the output end of the cylinder, and an electric push rod fixedly connected to one side of the moving block.

[0006] Preferably, the grinding box has a door on one side, the door is rotatably connected to the grinding box via a hinge, the door has an observation window inside, and a hand groove is provided on one side inside the door.

[0007] Preferably, a spring is fixedly connected between one side of the fixed base and one side of the clamping plate.

[0008] Preferably, a driven wheel is fixedly connected to the top of the screw, a driving wheel is meshed with the outer side of the driven wheel, a connecting rod is fixedly connected to one side of the driving wheel, and the outer side of the connecting rod is fixedly connected to the output end of the first motor.

[0009] Preferably, the first motor is fixedly connected to the grinding box via a fixing plate.

[0011] Preferably, the cylinder is fixedly connected to the first grinding disc via a connecting plate.

[0012] Preferably, the output end of the electric push rod is fixedly connected to a second grinding disc.

[0013] Compared with the prior art, this utility model provides a valve flange grinding device for valve processing, which has the following beneficial effects:

[0014] 1. This utility model sets up a fixed base, with the valve flange placed on top of the fixed base. The telescopic rod and spring push the clamping plate to move inside the valve flange, so that the clamping plate contacts the inner side of the valve flange, thereby clamping and fixing the valve flange. This improves the stability of the valve flange during the grinding process. The structure is simple and easy to install. It can fix valve flanges with different internal diameters, thus expanding the applicability of the device.

[0015] 2. This utility model, by setting up a first grinding disc and a second grinding disc, uses a first motor to drive a connecting rod and a drive wheel to rotate. The drive wheel meshes with the driven wheel, thereby driving a screw to rotate. The screw is threadedly connected to a moving plate, enabling the moving plate to move the first grinding disc up and down, so that the bottom of the first grinding disc contacts the end face of the valve flange. An electric push rod pushes the second grinding disc to contact the side of the valve flange. Then, a second motor drives a rotating shaft to rotate, thereby rotating the first and second grinding discs. At the same time, a cylinder can push a moving block up and down, facilitating grinding at different heights on the side of the valve flange. This allows for simultaneous grinding of the end face and side of the valve flange, reducing grinding time, improving grinding efficiency, and increasing the practicality of the device.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description
