Description

Technical Field

[0001] The utility model relates to the technical field of piston rod storage, in particular to a piston rod placement rack. Background Art

[0002] The deformation of long shaft parts is common in all stages of machining of long shaft parts, especially the thin and long piston rod body. The piston rod body is very easy to deform during storage. The main reason is that the existing piston rods are generally placed directly on the ground with square wooden pillows. Although this method is relatively direct, the ground cannot be absolutely flat, and there are mostly point contacts between the piston rod and the wooden square. If stored for a long time, the suspended part or the supporting force part will inevitably deform.

[0003] Since the piston rod reciprocates in the oil cylinder, if there is any deformation, it will affect the smoothness of the movement of the piston rod, resulting in uneven force on the sealing ring, and the oil cylinder will leak oil, affecting the service life of the oil cylinder. Therefore, a piston rod placement device is very needed to solve the above problems.

[0004] In order to solve the above technical problems, a Chinese utility model patent application with publication number CN210757672U discloses a piston rod placement rack, which belongs to the field of mechanical processing technology. The left and right vertical plates are connected by three horizontal frame plates, one in the middle and the other in the lower. A pair of threaded holes are provided at both ends of the three horizontal frame plates. Bolts pass through the vertical plates and then are screwed into the threaded holes to fix the three horizontal frame plates. Base rods are welded at the bottom of the vertical plates. Support rods are welded between the base rods and the vertical plates. The width of the upper horizontal frame plate is the same as that of the vertical plate. The width of the middle horizontal frame plate is half of the width of the upper horizontal splint and is located below the front half of the upper horizontal frame plate. The width of the lower horizontal frame plate is half of the width of the middle horizontal frame plate and is located below the rear side of the middle horizontal frame plate. U-shaped notches with equal spacing are provided on the front and rear end surfaces of the three horizontal frame plates. The upper horizontal frame plate has a large-sized notch, the middle horizontal frame plate has a medium-sized notch, and the lower horizontal frame plate has a small-sized notch. The depth of the U-shaped notch is less than half of the width of the plate body. The U-shaped notch can hang a piston rod of a corresponding shaft diameter. This structure facilitates the placement of the piston rod to a certain extent, but if it encounters an external object, the bottom of the piston rod is not protected and is prone to swinging outward. If the swing amplitude is too large, it is easy to hit the staff and even knock down the entire rack. Therefore, how to design a piston rod placement rack that can increase the anti-collision force and ensure that the internal piston rod is stable and not easy to shake is a technical problem that technical personnel in this field currently need to solve.
