Description

Quick installation equipment for the open steel ring on the manual piston rod

technical field

The utility model relates to the field of mechanical manufacturing, in particular to a manual quick installation device for an upper opening steel ring on a piston rod.

Background technique

The piston rod is an important part of the cylinder and oil cylinder motion executive parts, and has a wide range of applications. Its main function is to support the piston to do work through reciprocating motion. During the reciprocating movement of the piston rod, the position of the accessories on the piston rod, such as the piston, the guide sleeve, etc., is limited. Usually, the opening steel ring is installed in the groove at a specific position on the piston rod to realize the position limitation. Therefore, the installation of the open steel ring on the piston rod is an indispensable part of the installation of the piston rod accessories, and also determines the quality of the cylinder. Due to the relatively high hardness of the split steel ring, currently in small and medium batch production, most enterprises use split ring pliers to install it manually, which is cumbersome and inefficient. In the face of fierce market competition, enterprises need to realize the fast and accurate installation of the steel ring on the piston rod.

Above-mentioned purpose of the utility model is realized through the following technical solutions:

Manual fast installation equipment for the open steel ring on the piston rod, including the open steel ring expanding mechanism 1 and the open steel ring conveying mechanism 2, the open steel ring expanding mechanism 1 and the open steel ring conveying mechanism 2 pass through the hole and the shaft The interference is connected together.

The opening steel ring expanding mechanism 1 is as follows: the upper end shaft of the opening steel ring expanding cylinder 101 is connected with the hole on the guide mandrel 201 with interference, and the lower end is sleeved on the front end of the piston rod 4 to be processed.

The open steel ring conveying mechanism 2 is: one end of the compression spring 203 is located in the groove at the upper end of the guide mandrel 201, the other end is connected to the compression spring end cover 204, and the compression spring end cover 204 is connected to the grip sleeve 205 by screws. Together, the limit pin 202 passes through the through hole on the guide mandrel 201, and its end is located in the U-shaped groove on both sides of the handle sleeve 205, which limits the movement distance of the handle sleeve 205, thereby opening The steel ring 3 is accurately delivered to the designated location.

The beneficial effects of the utility model are: simple structure, simple and quick operation, and precise installation. The split ring is expanded by using the expander instead of the traditional split ring pliers. It is easy to use, simple in structure and low in cost. Improve production efficiency and save production cost. Strong practicality.

Detailed ways

Further illustrate the detailed content of the utility model and its specific implementation below in conjunction with accompanying drawing.

Referring to Fig. 1 to Fig. 3, the manual fast installation equipment for the open steel ring on the piston rod of the utility model makes the installation of the open steel ring on the piston rod convenient and fast, and improves the production efficiency under the premise of ensuring the assembly quality . It includes a split steel ring expansion mechanism 1 and a split steel ring delivery mechanism 2. The split steel ring expansion mechanism 1 is connected to the hole on the guide mandrel 201 in the split steel ring delivery mechanism 2 through a small interference connection between the hole and the shaft. together.

Referring to Fig. 2, the described opening steel ring expansion mechanism 1 is: the upper end shaft of the open steel ring expansion tube 101 and the hole on the guide mandrel 201 are connected together through the small interference of the hole and the shaft, and the lower end sleeve At the front end of the piston rod 4 to be processed.

Referring to Fig. 3, the described open steel ring conveying mechanism 2 is: one end of the compression spring 203 is located in the groove on the upper end of the guide mandrel 201, and the other end is connected to the compression spring end cover 204, and the compression spring end cover 204 is connected by a screw and a hand. The holding sleeve 205 is connected together, the limit pin 202 passes through the through hole on the guide mandrel 201, and its end is located in the U-shaped groove on both sides of the holding sleeve 205, and the movement distance of the holding sleeve 205 plays a role. The limit function, so that the split steel ring 3 can be accurately transported to the designated position. When the sleeve 205 is pulled down, the open steel ring 3 moves down along the open steel ring expansion tube to the designated position on the piston rod to be assembled, so as to realize the fast and accurate installation of the steel ring. Using the expander to expand the split ring instead of the traditional split ring pliers makes the operation easier and improves the production efficiency; simply changing the size of a few parts can be applied to the assembly of different types of piston rods. It has a wide range of applications and is especially suitable for the degree of automation. Not high small and medium batch production.

Referring to shown in Fig. 1 to Fig. 3, the work process of the present utility model is as follows:

Align the opening of the split steel ring 3 with the opening of the split steel ring expansion tube 101, install the split steel ring 3 on the split steel ring expansion tube 101, and start the split steel ring 3 along the slope of the split steel ring expansion tube 101 Slide down a little, because the diameter of the lower part of the split steel ring expansion tube 101 is larger than the inner diameter of the split steel ring, so the split steel ring 3 will not slide down all the time; the diameter of the lower part of the grip sleeve 205 is smaller than the outer diameter of the split steel ring 3, so When the sleeve 205 is pulled down, the open steel ring 3 will move down along the open steel ring expansion tube 101, and the open steel ring 3 will be enlarged; when the upper end of the U-shaped groove on the sleeve 205 touches the limit pin When holding the sleeve 205 at 202, the downward movement is stopped, so the distance of the downward movement of the split steel ring 3 can be set, thereby ensuring that the split steel ring 3 is installed at a specific position of the piston rod 4, and realizing that the split steel ring 3 precise installation.
