Gas-liquid pressurization type pinion press-fitting machine

Abstract

The invention relates to the technical field of gear press fitting, in particular to a gas-liquid pressurization type pinion press fitting machine. According to the technical scheme, the device comprises a base, a connecting plate, a supporting plate, a protective cover and a first connecting block, the connecting plate is installed on one side of the outer wall of the upper end of the base, the supporting plate is arranged on one side of the outer wall of the upper end of the base, the first connecting block is installed in the supporting plate, and a second connecting block is arranged in the first connecting block; a third connecting block is arranged in the second connecting block, safety grating bodies are installed on the outer walls of the two sides of the connecting plate, a pushing device body is installed on one side of the upper end of the inner wall of the connecting plate, and the effect of improving the press-fitting efficiency is achieved by arranging the connecting plate, a supporting plate and a protective cover; and the situation that workers need to replace the positioning jig manually is avoided, the press-fitting efficiency of the gear is improved, the output efficiency of equipment is guaranteed, the situation that splashed chippings injure the workers is avoided, and the use safety of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of gear press-fitting, in particular to a gas-liquid pressurized pinion press-fitting machine. Background technique [0002] Gear refers to a mechanical element that continuously meshes with gears on the rim to transmit motion and power. When the gear is mounted on the outside of the drive shaft, the drive shaft needs to be press-fitted into the gear through a press-fitting device, while the existing press-fitting device Usually, a gas-liquid supercharger is used as the power mechanism. The working principle of the gas-liquid supercharger is similar to that of a pressure supercharger. It applies a very low pressure to the large-diameter air-driven piston. When this pressure acts on a small-area piston, generate a high pressure. The booster pump can be operated continuously by means of a 5 / 2 air-controlled reversing valve. The high-pressure plunger controlled by the one-way valve continuously discharges the...

Problems solved by technology

[0004] During the use of the existing press-fitting mechanism, for gears of different sizes, the staff needs to manually replace the positioning jig, and the replacement efficiency is low, which directly affects the press-fitting efficiency of the gears and the output efficiency of the equipment. Moreover, the existing press-fitting mechanism lacks a protective structure and cannot cover the gears. When the gears break during the press-fitting process, the flying debris will cause harm to the staff, resulting in low equipment safety.
