Abstract

The utility model discloses a piston ring assembly machine which comprises a machine frame. Two or more assembly mechanisms are arranged on the machine frame. Each assembly mechanism comprises a workbench, a connecting rod and a pressing board. Each pressing board is provided with a guide hole, each connecting rod perpendicularly penetrates through the corresponding guide hole and is fixed to the corresponding workbench, and each pressing board is driven by a screw rod nut pair to move vertically along the corresponding connecting rod. Each connecting rod is sleeved with a piston ring sleeve, multiple piston rings are arranged between each connecting rod and the corresponding piston ring sleeve, and each piston ring sleeve and the corresponding piston rings respectively move vertically along with the corresponding pressing board. When each assembly mechanism is in work, each pressing board drives the corresponding piston ring sleeve and the corresponding piston rings to move upwards and the piston rings are pressed into piston grooves through the corresponding piston ring sleeve. Due to the fact that two or more assembly mechanisms are arranged on the piston ring assembly machine, each pressing board is driven by the corresponding screw rod nut pair to accurately control the strength and the speed of upward motion of the corresponding piston rings, the piston rings are accurately pressed into the piston grooves, the assembly mechanisms can be operated by operators in turn, waiting time of the workers is saved, and the work efficiency is improved.

Description

Piston ring assembly machine

technical field

The utility model relates to the field of metal processing, in particular to a piston ring assembly machine.

Background technique

At present, when installing the piston ring, the piston ring is mostly pressed into the piston by manual operation. Not only is the operation efficiency low, but more operators are required, and the manual pressing of the piston ring usually has deviations in the pressing position and deviation. The piston ring will cause the cylinder to leak air or scratch the cylinder. In order to avoid these problems, after manually pressing the piston ring, it needs to pass inspection. If the position is found to be inaccurate, it needs to be taken out and re-pressed. This is time-consuming and laborious.

Piston ring assembly machine, the piston ring assembly machine includes a frame, the frame is provided with more than two sets of assembly mechanisms, the assembly mechanism includes a workbench, a connecting rod, and a pressure plate, and the pressure plate is provided with a guide hole , the connecting rod is vertically pierced with a guide hole and fixed on the workbench, the pressure plate is driven by the screw nut pair to move up and down along the connecting rod; the outer cover of the connecting rod is provided with a piston ring sleeve, and the connecting rod and There are multiple piston rings between the piston ring sleeves, and the piston ring sleeves and piston rings move up and down with the pressure plate; when the assembly mechanism is working, the piston is fixed on the positioning structure on the top of the connecting rod, and the pressure plate drives the piston ring sleeve and the piston The rings move upwards, and under the action of the piston ring sleeve, the piston ring is pressed into the piston groove.

A guide sleeve is fixed on the guide hole of the pressure plate, and the guide sleeve is sleeved outside the connecting rod. The setting of the guide sleeve can drive the movement of the piston ring sleeve more accurately.

There are two sets of assembly mechanisms.

The piston ring assembling machine of the utility model is equipped with more than two sets of assembling mechanisms at the same time, so that the operator can operate more than two sets of assembling mechanisms in turn, saving workers' waiting time and improving work efficiency. The pressure plate is driven by the screw nut pair to precisely control the strength and speed of the upward movement of the piston ring, and the piston ring to be assembled is accurately pressed into the piston groove.

As shown in Figures 1-3, the utility model piston ring assembly machine, the piston ring assembly machine includes a frame 1, the frame 1 is provided with more than two sets of assembly mechanism 2, the assembly mechanism 2 includes a working Platform 21, connecting rod 22, pressing plate 23, described pressing plate 23 is provided with guide hole 24, and described connecting rod 22 vertically passes through guiding hole 24 and is fixed on the workbench 21, and described pressing plate 23 is made of screw mandrel nut pair 4 Drive to move up and down along the connecting rod 22; the outer sleeve of the connecting rod 22 is provided with a piston ring sleeve 25, and a plurality of piston rings 26 are arranged between the connecting rod 22 and the piston ring sleeve 25, and the piston ring sleeve 25 and The piston ring 26 moves up and down with the pressure plate 23; when the assembly mechanism 2 is working, the piston 3 is fixed on the positioning structure 28 on the top of the connecting rod 22, and the pressure plate 23 drives the piston ring sleeve 25 and the piston ring 26 to move upward, and the piston ring sleeve Under the action of 25, the piston ring 26 is pressed into the piston groove.

A guide sleeve 27 is fixed on the guide hole 24 of the pressure plate 23 , and the guide sleeve 27 is sheathed outside the connecting rod 22 . The setting of the guide sleeve 27 can drive the movement of the piston ring sleeve 25 more accurately.

There are two sets of the assembly mechanism 2 .

The working process of the piston ring assembly machine of the utility model is: the piston ring 26 to be assembled is pre-set on the connecting rod 22, and then the piston 3 is placed on the positioning structure 28 on the top of the connecting rod 22, and the screw nut pair 4 Driven by the driving force, the pressure plate 23 presses the piston ring 26 vertically upward along the connecting rod 22 into the piston groove through the piston ring sleeve 25, thus completing the work of assembling the piston ring 26 for a piston 3; taking off the assembled piston 3. On the positioning structure 28 at the top of the connecting rod 22, replace the new piston 3 to be assembled with the piston ring 26, and repeat the work; After the piston is installed, the operator can replace the piston 3 for another assembly mechanism 2 while waiting for the assembly to be completed. Such an operation improves the work efficiency of the operator.
