Description

Technical Field

[0001] The utility model relates to the technical field of piston ring disassembly devices, and specifically relates to a piston ring disassembly device. Background Technique

[0002] A piston ring is a metal ring used to be embedded inside a piston groove. Piston rings are divided into two types: compression rings and oil rings. Compression rings can be used to seal the combustible mixture inside the combustion chamber; the oil ring is used to scrape off the excess oil on the cylinder. A piston ring is a metal elastic ring with a large outward expansion and deformation. It is assembled into the corresponding annular groove of its cross-section. The reciprocating and rotating piston rings rely on the pressure difference of gas or liquid to form a seal between the outer circular surface of the ring and the cylinder and one side of the ring and the ring groove.

[0003] The prior art can disassemble the piston ring manually. However, when manually spreading the piston ring, it is necessary to always maintain the manually spread state to disassemble it. In addition, if too much force is used during manual disassembly, it is easy to cause the piston ring to break and hurt the staff. Therefore, those skilled in the art have provided a piston ring disassembly device to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to provide a piston ring disassembly device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A piston ring disassembly device includes a guide rail, a handle, an arc-shaped clamping plate and a fixing ring. A chute is opened on the front surface of the guide rail, and a servo motor is fixedly installed at the upper end of the guide rail. The power output end of the servo motor is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the guide rail. The lower end of the rotating shaft is fixedly connected to a first bevel gear, and a second bevel gear is meshed on one side of the first bevel gear. A left threaded rod is fixedly connected to the left side of the second bevel gear, and the left threaded rod is rotatably connected to the guide rail. A right threaded rod is fixedly connected to the right side of the second bevel gear, and the right threaded rod is rotatably connected to the guide rail.

[0007] As a further scheme of the utility model: Sliders are threadedly connected to both the left threaded rod and the right threaded rod, and the sliders are clamped in the chute. The rear end of the guide rail is fixedly connected to a handle, and the front end of the guide rail is fixedly connected to a fixing ring.

[0008] As a further scheme of the utility model: Two groups of left and right spring rods are penetrated through the fixing ring, and arc-shaped clamping plates are fixedly connected to one ends of the spring rods, and grooves are opened on one side of the arc-shaped clamping plates.

[0009] As a further solution of the utility model: slots are provided on the front surfaces of the sliders, support blocks are inserted into the slots, and fixing screws are threadedly connected to one sides of the sliders. The support blocks can be fixed on the sliders by the fixing screws.

[0010] As a further solution of the utility model: a first control button is arranged on the upper side of the handle, a second control button is arranged behind the first control button. The second control button is arranged on the handle, a storage battery is clamped inside one side of the handle, and a battery cover is hinged to one side of the handle.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. Fit the left and right support blocks to the inner side of the opening of the piston ring, and start the servo motor, so that the left and right support blocks can move to the left and right sides. Then the support blocks can stably expand the piston ring, which is convenient for the subsequent disassembly of the piston ring. The depth of the support blocks in the slots can be adjusted, so as to be suitable for the transverse lengths of different piston ring openings.

[0013] 2. When disassembling, the piston ring will be expanded, and a part of the outer side of the piston ring will be stuck in the groove of the arc-shaped clamping plate. Under the action of the spring rod, the arc-shaped clamping plate will clamp and fix the piston ring. In this way, the piston ring can be prevented from falling off the disassembly device, and the piston ring can be prevented from hurting the staff after breaking. Description of the Drawings

A chute 2 is opened on the front surface of the guide rail 1, and a servo motor 5 is fixedly installed at the upper end of the guide rail 1. A rotating shaft is fixedly connected to the power output end of the servo motor 5. The rotating shaft is rotatably connected to the guide rail 1, and a first bevel gear 6 is fixedly connected to the lower end of the rotating shaft. A second bevel gear 7 is meshed on one side of the first bevel gear 6. A left threaded rod 3 is fixedly connected to the left side of the second bevel gear 7. The left threaded rod 3 is rotatably connected to the guide rail 1. A right threaded rod 4 is fixedly connected to the right side of the second bevel gear 7.
