The to-be-solved technical problem of the utility model is to provide a satisfy the atress requirement to the cylinder piston rod and the piston connection structure of the concentricity at piston rod both ends have fully been guaranteed. A connecting structure of a piston rod and a piston of a cylinder comprises an end cover and the like; a movable piston seat is arranged between the end covers, a piston rod is arranged on the end covers and the piston seat and is in transmission connection with the piston seat, a groove is formed in the piston rod and corresponds to the piston seat, and fillers are pressed into the groove through a riveting tool. The utility model discloses reach and satisfy the atress requirement to the effect of the concentricity at piston rod both ends has fully been guaranteed.
Description
Technical Field
The utility model relates to a cylinder especially relates to a piston rod of cylinder and piston connection structure.
Background
The utility model provides a cylinder piston rod and piston connection structure, its piston rod divide into two sections, and middle screw rod that uses is connected, because machining error and equipment error lead to both ends piston rod concentricity not good like this, can not satisfy customer operation requirement in some important occasions, consequently need to research and develop a cylinder piston rod and piston connection structure who satisfies the atress requirement to the concentricity at piston rod both ends has fully been guaranteed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome a piston rod of cylinder and piston connection structure, its piston rod divide into two sections, and the centre is connected with the screw rod, because machining error and equipment error lead to both ends piston rod concentricity not good like this, can not satisfy customer operation requirement's shortcoming in some important occasions, the to-be-solved technical problem of the utility model is to provide a satisfy the atress requirement to the piston rod of cylinder and the piston connection structure of the concentricity at piston rod both ends has fully been guaranteed.
The utility model is achieved by the following concrete technical means:
a connecting structure of a piston rod and a piston of an air cylinder comprises an end cover, a cylinder barrel, a piston seat, a piston rod and filler; the end covers are arranged in two ends of the cylinder barrel, the movable piston seat is arranged between the end covers, the piston rod is arranged on the end covers and the piston seat and is in transmission connection with the piston seat, the piston rod is provided with a groove, the groove is corresponding to the piston seat, and the filler is pressed into the groove through a riveting tool.
Further, the number of the grooves is two.
Further, the filler is a piston material.
Furthermore, the riveting tool is a special riveting tool for the piston rod and the piston seat.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses reach and satisfy the atress requirement to the effect of the concentricity at piston rod both ends has fully been guaranteed.
The utility model respectively processes the piston seat and the piston rod, and two grooves are processed on the piston rod for absorbing the material extruded by the special piston seat under the action of external force; during assembly, a special piston rod and a piston seat riveting tool are adopted, fillers are extruded into two grooves of the piston rod and are fully filled, and the fillers and the piston are made of residual materials, so that the energy-saving requirement is met, and the structure is tested by pressure resistance, so that the structure can completely meet the stress requirement, and the concentricity of two ends of the piston rod is fully guaranteed.
