Description

Technical Field

[0001] The utility model relates to the technical field of compressor air valve plate processing, in particular to a clamp for processing a reciprocating compressor air valve plate. Background Art

[0002] At present, piston compressors are widely used in industrial production, and the stability of their operation is particularly important. The air valve is one of the key components of the piston compressor. It is usually installed on the compressor cylinder to control the inlet and outlet of the gas. The structure and performance of the air valve have a great influence on the exhaust volume, power consumption and reliability of the piston compressor. It is often compared to the "heart" of the piston compressor. Nowadays, the air valve used for piston compressors is usually an automatic valve, and its opening and closing are mainly determined by the pressure difference between the gas in the cylinder and the valve cavity. As we all know, the core components of the air valve usually include a valve seat, a valve plate, a spring and a lift limiter. Among them, the valve seat has a gas channel that can be covered by the valve plate. It is a part that closes the intake (or exhaust) channel together with the valve plate and bears the pressure difference between the inside and outside of the cylinder; the valve plate is used to open or close the valve seat channel, and is usually made into a sheet, ring or mesh; the spring is a component that pushes the valve plate to fall to the valve seat when closed, and inhibits the valve plate from hitting the lift limiter when opened; the lift limiter is a component that limits the lift of the valve plate.

[0003] The existing technology requires the valve plate to be finely processed, including milling, turning, drilling and other processes to meet the size and surface quality requirements of the valve plate. Various processing equipment and tools, such as CNC machine tools, milling machines, lathes, etc., are used in this step to ensure that the valve plate reaches the precise size and shape. Therefore, the valve plate needs to be clamped and fixed during the processing. The existing clamping and fixing mechanism has a single clamping size, and different sizes of workpieces need to be replaced with different fixtures, which has low processing efficiency. Utility Model Content

[0004] In order to solve the deficiencies mentioned in the above-mentioned background technology, the purpose of the utility model is to provide a clamp for processing valve plates of reciprocating compressor air valves. By rotating the rotating handle, the screw sleeve moves up and down on the support rod, thereby driving the ring to move up and down, and the rotating rod and the clamp assembly rotate around the connection, thereby reducing or increasing the distance between multiple clamp assemblies, thereby adjusting the diameter of the clampable valve plate, realizing the clamping of valve plates of different diameters, and improving the versatility and processing efficiency of the clamp.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

By rotating the rotating handle 5, the screw sleeve 4 moves up and down on the support rod 2, thereby driving the collar 6 to move up and down, and the rotating rod 7 and the fixture assembly rotate around the connection, thereby reducing or increasing the distance between multiple fixture assemblies, thereby adjusting the diameter of the clampable valve disc, realizing the clamping of valve discs of different diameters, and improving the versatility and processing efficiency of the fixture.

[0025] Further preferably, the leveling rod 9 and the rotating rod 7 are arranged parallel to each other, and the leveling rod 9 and the rotating rod 7 have the same length. This ensures that the clamp assembly maintains stability during movement and adjustment.

[0026] Further preferably, a fixing ring 10 is fixedly connected to one end of the collar 6 away from the rotating rod 7, a sliding sleeve 11 is sleeved on the collar 6, a spring 12 is sleeved on the collar 6, the spring 12 is located between the fixing ring 10 and the sliding sleeve 11, the two ends of the spring 12 are respectively fixedly connected to the fixing ring 10 and the sliding sleeve 11, a pull rod 13 is rotatably connected to the sliding sleeve 11, the top end of the pull rod 13 is rotatably connected to an inner rod 14, and the inner rod 14 penetrates the parallel plate 8. Through the elastic force of the spring 12, the sliding sleeve 11 can be kept at a certain position on the collar 6, so that the clamping width of the clamp assembly can be adjusted through the pull rod 13 and the inner rod 14.

[0027] Further preferably, the clamp assembly includes a first clamping plate 15 and a second clamping plate 16, wherein the first clamping plate 15 is fixedly mounted on the parallel plate 8, and the second clamping plate 16 is fixedly mounted on the inner rod 14, and the first clamping plate 15 and the second clamping plate 16 are parallel to each other.

[0033] Adjust the clamping width: First, pull the rod 13 outward to make the sleeve 11 slide outward on the collar 6 and stretch the spring 12. At this time, the position of the inner rod 14 on the parallel plate 8 changes, thereby driving the second clamping plate 16 to move and further adjusting the distance between the first clamping plate 15 and the second clamping plate 16. When the appropriate width is adjusted, place the valve sheet to be processed between the first clamping plate 15 and the second clamping plate 16 to ensure that the valve sheet is firmly clamped, release the rod 13, and the elastic force of the spring 12 pushes the sleeve 11 back to its original position, fixing the position of the inner rod 14, thereby fixing the distance between the first clamping plate 15 and the second clamping plate 16.
