Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical assembly technical field, concretely is a kind of process equipment of assembling baffle ring for inner hole. BACKGROUND

[0002] Cylinder assembly is one of the core components of walking motor. Due to the structural characteristics of the product, the baffle ring for inner hole needs to be installed into the baffle ring groove of the cylinder hole to fix the spring inside the cylinder hole. Because the spring is rigid, two people are needed to work simultaneously for the assembly of the baffle ring for inner hole. One person presses down the pressure rod of the hand-operated press to keep the spring in a contracted state, and the other person uses a spring clamp to manually assemble the baffle ring for inner hole. This assembly method not only has high labor intensity and low efficiency, but also cannot accurately control the assembly position of the baffle ring for inner hole. Improper assembly of the baffle ring for inner hole can easily cause the baffle ring for inner hole to fall out of the baffle ring groove, which can cause unstable output and even failure of the driving system, aggravate mechanical wear and tear, and pose a safety hazard, thereby affecting the normal use of the walking motor.

[0003] Publication No. CN222037485U discloses an assembly tool for a steel wire baffle ring for hole, which comprises a pressure head and a guide sleeve. The two ends of the guide sleeve are respectively provided with a through hole A and a through hole B that are in communication with each other. The diameter of the through hole A is the same as the outer diameter of the shaft. The through hole B is in the shape of a circular truncated cone from inside to outside. The diameter of the end of the through hole B close to the shaft is the same as the inner hole diameter of the shaft. The pressure head is in the shape of a column. The through hole A of the guide sleeve is sleeved on the shaft. The steel wire baffle ring is placed in the through hole B of the guide sleeve. The pressure head pushes the steel wire baffle ring, and the steel wire baffle ring enters the inner hole of the shaft under the guidance of the through hole B.

[0004] When the existing technology is used for the installation of the baffle ring for inner hole of the cylinder, the static friction force between the gasket and the baffle ring for inner hole can affect the clamping of the baffle ring for inner hole into the baffle ring groove.
