Guide plate sprocket wheel detection device

Abstract

The invention discloses a guide plate sprocket wheel detection device, which comprises a push cylinder, a driving motor, a fixation block and a sprocket wheel. The sprocket wheel is engaged with a chain on a guide plate; the fixation block is in an L-shaped structure formed by two metal plates; a rotation shaft of the driving motor is connected with a speed reducer; an output shaft of the speed reducer passes through one metal plate of the fixation block, and is sleeved by a main shaft; a base is provided with a torque detection assembly; the torque detection assembly is linked with a connecting shaft; and during detection, the push cylinder pushes the fixation block to the guide plate, and enables the sprocket wheel to be engaged with the chain on the guide plate. According to the guide plate sprocket wheel detection device, through the arrangement of the driving motor and the sprocket wheel, the guide plate chain can be driven to rotate through a sprocket wheel engaging manner; and meanwhile, through arrangement of the torque detection assembly, output torque of the driving motor can be detected effectively, such that whether the current guide plate sprocket wheel is too tight or too loose can be detected.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for a guide plate sprocket. Background technique [0002] During the production process of the guide plate, a sprocket needs to be sandwiched between the two guide plates. After the riveting of the two guide plates is completed, the production of the guide plate can be initially completed by installing a chain on the guide plate. [0003] However, in the prior art, the riveting tightness of the guide plate is uncertain, and it is very likely that the guide plate clamps the sprocket too tightly or too loosely, which will affect the rotation of the sprocket during the use of the chainsaw. Influence, that is, when the clamp between the guide plates is too tight, the friction between the sprocket and the guide plate becomes larger, making it difficult to rotate the sprocket, and when the clamp between the guide plates is too loose, the friction between the sprocket and the gui...

[0003] However, in the prior art, the riveting tightness of the guide plate is uncertain, and it is very likely that the guide plate clamps the sprocket too tightly or too loosely, which will affect the rotation of the sprocket during the use of the chainsaw. Influence, that is, when the clamp between the guide plates is too tight, the friction between the sprocket and the guide plate becomes larger, making it difficult to rotate the sprocket, and when the clamp between the guide plates is too loose, the friction between the sprocket and the guide plate If the friction force is too small, the rotation speed of the sprocket will be faster than that of the gear in the chain saw body during the use of the chain saw, and the problem of loose chain will easily occur, so it is necessary to adjust the guide plate. The installation situation is tested, and when the installation situation of the existing guide plate is tested, the chain on the guide plate is manually pulled to realize the detection, and the human feeling is used to judge whether the guide plate is installed too loosely or too loosely. However, using the manual method first requires the inspector’s hand feeling to be very accurate. At the same time, using the hand feel method cannot be digitized, so the accuracy of the inspection is not high enough, and it is easy to make detection errors, resulting in quality problems of the subsequent guide plate. question
