Description
Technical Field
The utility model relates to a fan blade dynamic balance detects technical field, especially indicates a combination use mechanism for angle location sign.
Background
The fan is a conventional facility for reducing the temperature of equipment and the ambient temperature in industry and life. Through simple rotary motion of the blades, air convection is formed in local areas, so that hot air is dissipated, and the aim of cooling is fulfilled.
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 the mold, and errors in processing and assembling, etc., so that the mass distribution thereof with respect to the axis is not uniform, thereby generating 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, the balance testing and correction thereof is 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 points on the surface of the fan blade F are calibrated by a fixed cursor, as shown in fig. 1, the star light points on the surface of the fan blade F are calibrated by a laser head 5, so that the initial test position is consistent with the test position of the test software, and in the adjustment process, skilled working skills of a user are required, so that the defects of low labor efficiency and the like are caused.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a combination use mechanism for angle location sign.
The utility model adopts the following technical scheme: a combined use mechanism for angle positioning marks comprises a machine table, a fan blade dynamic balancing machine and a laser head, wherein the fan blade dynamic balancing machine is fixed on the machine table, the laser head is fixed on one side of the machine table, a supporting plate is covered at the output position of a transmission shaft of the fan blade dynamic balancing machine and fixed on the machine table, and hole positions are formed in the output position of the transmission shaft of the supporting plate; the hole site-specific scale is covered with a scale matched with the hole site, and the circumferential surfaces of the two sides of the scale are engraved with 360-degree graduations.
The 360 degrees graduations on the circumferential surfaces on the two sides of the dial are opposite to each other.
The position where the hole position of the supporting plate is jointed with the dial is provided with a step for accommodating the dial.
The steps of the hole positions of the supporting plate are tightly matched with the outer edge of the dial.
The utility model discloses owing to adopt radium-shine laser head and calibrated scale combination to use, the concrete position of the star light spot on location flabellum F surface that can be quick to make it initial test position unanimous with test software's test position, rapid completion flabellum unbalance amount and the test work of the demarcation of angle of locating.
