Flywheel fixing tool for semi-automatic pin assembly mechanism

Abstract

The invention discloses a flywheel fixing tool for a semi-automatic pin assembly mechanism and relates to the technical field of installation of machinery. The flywheel fixing tool comprises an L-shaped base, a n-shaped avoiding plate, a bearing platform, a bearing plate, a push mechanism and an inserting mechanism; and the avoiding plate is fixed to the upper end of the bearing platform and is used for limiting the output end of a downward-pressing device. A pin feeding device is used for feeding a pin into the fixing tool disclosed by the invention; subsequently the bearing plate is presseddown by the output end of the downward-pressing device; the push mechanism is used for pushing the inserting mechanism to move upwards so as to realize automatic assembly of the pin; after assembly isended, the downward-pressing device is reset and returned; the bearing plate is used for driving a flywheel disc to move upwards under the elasticity effect of a reset spring; an operator can place aflywheel on the bearing plate or take down the flywheel from the bearing plate simply; the potential safety hazards are eliminated; and the production efficiency is improved as well.

Description

technical field [0001] The invention relates to the technical field of mechanical installation, in particular to a flywheel fixing tool of a semi-automatic pin assembly mechanism. Background technique [0002] The flywheel is a large disc-shaped part installed on the rear end of the crankshaft of the engine. The flywheel stores a part of the work input to the crankshaft during the work stroke with its own moment of inertia, and is used to overcome resistance in other strokes and drive the crank connecting rod. The mechanism crosses the top and bottom dead centers to ensure that the crankshaft rotation angular velocity and output torque are as uniform as possible, and make it possible for the engine to overcome short-term overload. During the processing of the flywheel, it is necessary to insert pins into the pin holes to transmit power And torque and realize the dynamic balance of the flywheel. [0003] At present, when our company performs pin assembly on the flywheel, the...

AI Technical Summary

Problems solved by technology

[0003] At present, when our company performs pin assembly on the flywheel, the method used is to place the flywheel disc directly on the fixed column in the fixed area. There is no special flywheel fixing tool, and then manually use a hammer to knock the pin into the pin hole to complete the assembly. During the long-term production and assembly process, it was found that manual placement of pins is easy to accidentally injure the operator, and there are potential safety hazards. Moreover, the operation requirements for the operator are high, but the production efficiency is not high, which cannot meet the current production needs.
