Description

Technical Field

[0001] This utility model belongs to the field of balance shaft machining technology, specifically involving a precision machining fixture for balance shaft mechanisms. Background Technology

[0002] The function of an engine balance shaft is simple: to reduce engine vibration during operation. An engine equipped with a balance shaft will run more smoothly. The principle is also simple: the balance shaft is located with the crankshaft, and the direction of rotation of the balance shaft is opposite to that of the crankshaft, which can counteract some of the vibration. Usually, there are some balance weights on the engine balance shaft. The function of the engine balance bar is to reduce the vibration of the entire vehicle, make the engine run more smoothly, reduce noise, and improve riding comfort. Balance shaft technology is a widely used technology in motorcycle engines. Its structure is simple and practical, and it can effectively reduce the vibration of the entire motorcycle and improve riding comfort.

[0003] Currently available fixtures for balance shaft mechanisms are not fully functional when users need to clamp and adjust the balance shaft. Furthermore, auxiliary tools are required when users need to install the entire fixture, which increases the user's time and cost. Utility Model Content

[0006] The inner ring surface of the nut is fitted with a threaded rod for limiting, the inner ring surface of the connecting frame is fitted with a protective shell for limiting, and the inner ring surface of the protective shell is fitted with a connecting block.

[0007] A motor is installed on the side surface of the connecting block, a processing plate is fixedly sleeved on the top of the output shaft of the motor, a telescopic rod is installed on the side surface of the processing plate, a pressing plate is installed on the bottom surface of the telescopic rod, and a processing anti-slip plate is installed on the upper surface of the processing plate.

[0008] This utility model further illustrates that a protective shaft is fixedly connected to the inner surface of the protective shell, and the size of the protective shaft and the output shaft of the motor are matched.

[0009] The present invention further illustrates that the bottom surface of the support foot is fitted with a mounting plate, and there are multiple mounting plates that are parallel to each other.

[0010] The present invention further describes that the upper surface of the mounting plate is provided with mounting openings, and the number of mounting openings is multiple.

[0011] This utility model further illustrates that the nut is connected between a fixing block and a connecting frame, and the fixing block is symmetrically arranged with the vertical center line of the nut as the axis of symmetry.

[0014] This utility model provides a precision machining fixture for a balance shaft mechanism. Through the coordinated use of the precision machining fixture connecting main mechanism, support feet, mounting plate, mounting opening, nut, threaded rod, fixing block, connecting block, connecting frame, protective shell, machining anti-slip plate, machining plate, pressing plate, telescopic rod, motor, and protective shaft, it facilitates efficient adjustment of the machining fixture by the user. When the user needs to adjust the angle of the balance shaft mechanism, the user places the balance shaft mechanism on the machining anti-slip plate, then activates the telescopic rod. After activation, the telescopic rod pushes the pressing plate, thus clamping the balance shaft mechanism. After the user starts the motor, the motor drives the machining plate, which is fixedly sleeved at the top of its output shaft, to rotate, allowing the user to adjust the angle of the balance shaft mechanism by rotation. After the user tightens the threaded rod and loosens the nut, the user can adjust the vertical angle of the connecting frame on the precision machining fixture connecting main mechanism. This allows for efficient vertical angle adjustment of the machining fixture, meeting the user's needs for efficient machining and adjustment of the balance shaft mechanism.
