Description
Technical Field
The utility model relates to the technical field of fan blade dynamic balance detection, in particular to a mechanism for universal calibration of a fan laser origin.
Background
The fan is a conventional facility for reducing the temperature of equipment and the ambient temperature in industry and life. Through the simple rotary motion of the blades, air convection is formed in local areas, so that hot air is dissipated, and the purpose of cooling is achieved.
The direct current fan belongs to a rotary product from the mechanical motion angle, and can also be called a rotary body, and ideally, the rotary product has uniform mass distribution, so that the pressure generated by the rotary fan on a bearing is the same regardless of whether the rotary fan rotates or not. However, in practice, it is difficult to control the factors due to unevenness of material or defects of a mold, and errors in processing and assembling, etc., so that the mass distribution thereof with respect to the axis is not uniform, thereby generating a centrifugal force. This unbalanced centrifugal force acts on the bearings, which generates noise, accelerates product wear, and further severely affects product performance and life. In the production and manufacture of such products, balance testing and correction thereof are based on this application.
The existing fan blade dynamic balancing machine uses a motor to drive a fan, detects starlight points on the surface of the fan blade through a light beam detection instrument to reflect the unbalance of the fan blade, converts the unbalance into vibration quantity through a mechanical structure, and then carries out data processing on the vibration quantity through a computer to obtain the unbalance and the angle of the fan blade. However, in the conventional fan blade dynamic balancing machine, the star light spot on the surface of the fan blade F is calibrated by a fixed cursor, as shown in fig. 1, when the fan blades F with different dimensions are replaced, screws need to be removed to adjust the laser head 5 and the star light spot on the fan blade (defined as an origin point/a zero degree point/a reference point), so that the relative position is inconvenient to adjust; and the position range of the adjustment is small, only the near distance can be adjusted, and the left and right offset cannot be adjusted.
