Description

Technical Field

[0001] The invention relates to the technical field of balance shaft curvature detection, in particular to a tool for detecting curvature of a balance shaft of an automobile engine. Background Art

[0002] Balance shaft technology is a widely used technology in automobile engines. It has a simple and practical structure and can effectively reduce the vibration of the entire vehicle and improve driving comfort. Simply put, the balance shaft is actually a shaft equipped with an eccentric weight and rotates synchronously with the crankshaft. The reverse vibration force generated by the eccentric weight is used to make the engine obtain a good balance effect and reduce engine vibration. The balance shaft is used to balance and reduce the vibration of the engine, thereby reducing engine noise, extending service life, and improving driver and passenger comfort. However, not all engines require a balance shaft. For example, "V"-type and horizontally opposed engines, these engines already have good vibration balance and there is no need to design a balance shaft. There are two types of balance shafts used in engines: double balance shaft and single balance shaft. The two methods are the same in working principle, but the specific structure is different.

[0003] The balance shaft technology is a widely used technology in engines. It has a simple and practical structure, can effectively reduce the vibration of the whole vehicle, and improve driving comfort. The existing automobile engine balance shaft needs to be tested for the curvature of the balance shaft after production. To this end, the present invention provides an automobile engine balance shaft curvature detection tool (specifically refer to patent number: 202121774696.5), including a top plate, both sides of the bottom of the top plate are fixedly connected with a clamping mechanism, the bottom of the top plate is fixedly connected with a rodless cylinder, and the bottom of the rodless cylinder movable block is fixedly connected with a connecting tube, and the inner surface of the connecting tube is A spring is fixedly connected to the top, and a lifting plate is fixedly connected to the bottom end of the spring. The bottom of the lifting plate extends to the outside of the connecting tube, and a detection roller is rotatably connected to the bottom of the lifting plate. The automobile engine balance shaft curvature detection tooling, after the clamping mechanism clamps the balance shaft, drives the detection roller to slide horizontally along the surface of the balance shaft through the rodless cylinder, and judges whether the balance shaft curvature meets the requirements according to the lifting distance of the lifting plate, thereby realizing the detection of the balance shaft curvature. Through the graded adjustment setting of the stop column, the maximum lifting range of the lifting plate can be adjusted to adapt to balance shafts of different specifications, thereby improving the application scope of the device.
