Embodiment Construction
[0031] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.
[0032] Such as Figure 1-3 As shown, the centering installation method of the fan sample test in this preferred embodiment includes the following steps:
[0033] Step 1. Flip the test sample 1 to the angle to be tested;
[0034] Step 2. Laser crosshair installation: align the bracket structure as Figure 4-7 As shown, first connect the adapter block 21 to the test sample 1 through structural glue, and dry it with a hair dryer to cure the structural glue, then install the supporting plate 22 on the adapter block 21 with screws, Calibration determines that the supporting plate 22 is located on a horizontal plane, the screw 23 passes through the supporting plate 22 and is fixed by a flange nut 24, and finally the laser crosshair is installed on the supporting plate 22 through the screw 23;
[0035] Step 3. Adjustment of the la...

The invention discloses an aligning bracket and a centering installation method. The aligning bracket comprises an adapter plate, a support plate, and a screw. The adapter plate and the support plate are connected through screws. The screw passes through the support plate and is fixed by a flange screw nut. The method centering installation comprises the following steps: turning a test sample piece into an angle to be tested; then successively installing an adapter block, the support plate, a laser cross curve instrument; adjusting the laser cross curve instrument in order that a horizontal line emitted from the laser cross curve instrument coincides with the horizontal line of the test sample piece; finally, enabling the cross curve emitted from the laser cross curve instrument to coincide with the standard cross curve of a projection plane to achieve the centered installation of the test sample piece. The centering installation method converts the position parameters of a blower fan sample piece posture into the cross curve for fitting so as to greatly improve the centering installation speed of the blower fan sample piece, solve the various drawbacks in a visual inspection method and improve the use efficiency of the whole test platform and a test operator safety factor.
Description
technical field [0001] The invention relates to an alignment bracket and a centering installation method for fan sample testing. Background technique [0002] In today's global energy shortage and emphasis on environmental protection, the development of renewable energy has undoubtedly become an important part of sustainable development. Wind energy is a clean and renewable energy. According to the analysis of the World Meteorological Organization (WMO), the total global wind energy is 3×10 17 kW, of which the available wind energy is 2×10 10 kW. In wind turbines, composite material components mainly include blades, nacelle covers, shrouds, etc., among which the blades are the most used. Fan blades have the characteristics of large size, complex shape, high precision requirements, high requirements for strength and stiffness, high surface roughness requirements, and good quality distribution uniformity. It is the core part of the entire fan, accounting for 1 / 4 to 1 / 3 of ...
