Abstract
The utility model discloses a connecting structure convenient for matching a threaded sleeve with a piston rod, which comprises a piston rod and a threaded sleeve arranged on the piston rod; the device is characterized by further comprising a matching filling strip which is arranged on the piston rod and the threaded sleeve in an interference fit mode. The utility model has simple structure, convenient installation and low requirement on size, reduces the processing procedures and improves the production efficiency.
Description
Technical Field
The utility model relates to the technical field of connection modes, in particular to a connection structure convenient for matching of a threaded sleeve and a piston rod.
Background
The piston rod is generally applied to a hydraulic cylinder or an air cylinder, in the prior art, when the piston rod and the thread insert are installed, the thread insert is provided with a knurling shape on the surface matched with the thread insert to increase the size of the thread insert and install the piston rod, so that the machining process is increased, the production efficiency is reduced, or the size of the thread insert and the surface matched with the piston rod is increased to achieve the effect of tight fit with the piston rod, but the size processed by the mode is large in requirement, and the thread insert is not convenient to install. Therefore, the connecting structure convenient for the matching of the threaded sleeve and the piston rod is provided.
Disclosure of Invention
The utility model aims to solve the problems that in the prior art, when a piston rod and a thread sleeve are installed, the thread sleeve is increased in size by adopting a knurled shape on a matched surface to install the thread sleeve and the piston rod, so that the processing procedure is increased, the production efficiency is reduced, the size of the matched surface of the thread sleeve and the piston rod is increased to be matched with the piston rod to achieve the tight fit effect, but the size processed by using the method is high in requirement, the installation is inconvenient and the like, and the connection structure convenient for matching the thread sleeve and the piston rod is provided.
In order to achieve the purpose, the utility model provides the following technical scheme: a connecting structure convenient for matching a threaded sleeve with a piston rod comprises the piston rod and the threaded sleeve arranged on the piston rod; the piston rod is characterized by further comprising a matching filling strip which is arranged between the piston rod and the thread sleeve in an interference fit mode.
Preferably, the piston rod and the thread sleeve are fixedly installed through interference fit with the matched filling strip.
Preferably, the matching filler strip is a steel wire.
Preferably, the piston rod is provided with a mounting hole matched with the thread sleeve.
The utility model has the beneficial effects that: the connecting mode has the advantages of simple structure, convenience in installation, low requirement on size, reduction in processing procedures and improvement on production efficiency.

Illustration of the drawings: 1 a piston rod; 101, mounting holes; 2, thread sleeve; 3 fitting a filling strip.
Detailed Description
The following description will further describe a connection structure for facilitating the engagement of the threaded sleeve and the piston rod according to the present invention with reference to the accompanying drawings.
Referring to fig. 1-2, a connection structure for facilitating the engagement between a threaded sleeve and a piston rod in the present embodiment includes a piston rod 1 and a threaded sleeve 2 mounted on the piston rod 1; the device is characterized by further comprising a matching filling strip 3 which is arranged between the piston rod 1 and the thread sleeve 2 in an interference fit manner; the piston rod 1 and the thread sleeve 2 are fixedly installed through interference fit with the matched filling strip 3; the matching filling strips 3 are steel wires; through the setting of cooperation packing strip 3 between piston rod 1 and swivel nut 2, fill in the clearance between piston rod 1 and swivel nut 2 through cooperation packing strip 3, make between piston rod 1 and swivel nut 2 and the cooperation packing strip 3 through interference fit looks fixed mounting to be convenient for the installation between piston rod 1 and the swivel nut 2, reduce the process of processing, improve the efficiency of production.
Referring to fig. 1-3, the piston rod 1 is provided with a mounting hole 101 adapted to the thread insert 2; through the setting of mounting hole 101 on the piston rod 1, swivel nut 2 is through installing on piston rod 1 with mounting hole 101 looks adaptation to the installation of swivel nut 2 is convenient for.
According to the utility model, when the piston rod 1 and the threaded sleeve 2 are installed, the threaded sleeve 2 is firstly matched with the installation hole 101 on the piston rod 1, a part of the threaded sleeve 2 is placed in the installation hole 101, then a plurality of matching filling strips 3 made of steel wires are placed in a gap between the threaded sleeve 2 and the installation hole 101 of the piston rod 1, and then the threaded sleeve 2 is knocked to enable the matching filling strips 3 and the threaded sleeve 2 to move downwards together and be fixedly installed in the installation hole 101 of the piston rod 1.
The above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any simple modifications of the present invention are within the scope of the present invention.
