Background

In the fan field, the detection of fan blades is vital, the precision of the height of the fan blades influences the performance of the fan, and if the height of the fan blades does not reach the required precision, the performance of the fan is inevitably influenced. In the detection process, manual direct measurement is generally adopted, although the operation steps are simple, the error is easy to see due to the fact that no process or tool is provided for ensuring, the detection is too subjective, the product quality completely depends on the responsibility of an operator, the quality is uncontrollable and unstable, for example, a mechanical vernier caliper is used for measuring a large batch of products, the error-seeing probability is very high, the production efficiency is low due to the fact that the detection is purely manual, automation is not facilitated, the mass production accuracy is low, and not only is the production efficiency low, but also the production efficiency is purely dependent on the experience of the operator, the operator needs to measure the lower height and the upper height and also needs to take the correction into consideration, and a new hand is easy to be busy and disorderly.

Chinese patent publication No. CN217483406U discloses an integrative detection device for measuring fan blade height, it includes: the base and the go gauge are used for detecting that the actual fan blade height accords with the preset fan blade height condition; the no-go gauge is arranged on the go gauge and used for detecting the height of the fan blade and the condition that the tolerance range of the fan blade meets the requirements; the fan blade inspection part is arranged on the base, is parallel to the go gauge and the no-go gauge and is used for installing and fixing the fan blade to be inspected; lead to the rule with the integrative setting of no-go gage for detect the size precision condition of fan blade height, lead to the rule and set up in the detection direction that corresponds and detect the groove, lead to the rule rigid coupling in the base has reduced the flow for product technology standardization and degree of automation are higher, have improved production efficiency, have reduced the cost of labor.

However, the above inventions and the background art have significant disadvantages: the device for automatically detecting the height of the fan blade is disclosed in the patent, but the length of the fan blade cannot be detected at the same time, so that whether the overall performance of the fan blade reaches the standard cannot be guaranteed only through the height detection, the length of the fan blade cannot be confirmed, the space range required by the circular motion of the fan blade cannot be confirmed, and the installation precision of the fan blade is also influenced.

Firstly, detecting the height and thickness of the blade:

referring to fig. 8, when the arc edge of the blade collides with the connecting rod 401, a thrust is provided to the rotatably connected connecting rod 401, so that the connecting rod 401 linearly moves in the sliding groove 3 through the sliding block 302, and referring to fig. 1, the sliding groove 3 is tangent to the periphery of the connecting shaft 201, so that when the connecting rod 401 is extruded by the arc edge of the blade, the moving direction of the connecting rod 401 and the arc edge of the blade form a larger included angle, thereby ensuring that the connecting rod 401 can normally horizontally slide;

referring to fig. 7, 8 and 9, in the process, the upper and lower first probes 404 respectively detect the distances between the top surface and the bottom surface of the rightmost end of the blade and the corresponding first probe 404, and the values detected by the upper and lower first probes 404 are a and c in sequence, and the detection data table refers to fig. 13;

the distance between the two first probe 404/second probe 405 on the same side is X, and referring to the schematic diagrams in fig. 9 and 12, it can be mathematically found that: x-a-d = blade height, X-a-c or X-b-d = blade thickness;

it should be noted that, in the process of measuring and calculating data by reciprocating movement, for example, the fan blade 2 is divided into a plurality of vertical areas, and the thickness of each area is applied to the formula of X-a-c or X-b-d = blade thickness, so that the data of a plurality of groups of thicknesses of the fan blade 2 can be monitored, and the uniformity of the blade thickness of the fan blade 2 can be compared.

Second, blade length detection

Referring to fig. 10, in the position of fig. 10, the distance between the horizontal probe 4 and the connecting shaft 201 is farthest, and when the connecting rod 401 is located at the rightmost side, that is, when the connecting rod is abutted against the outer wall of the connecting shaft 201, the distance between the horizontal probe 4 and the connecting shaft 201 is the smallest, so that the length of the blade is obtained by subtracting the minimum distance from the maximum distance;

therefore, along with the rotation of the fan blades 2, the length, thickness and height data of a plurality of groups of blades can be obtained at the same time, and the detection efficiency is improved;

it is noted that the first probe 404 and the second probe 405 are both laser detection probes.

The top of the connecting rod 401 is fixedly connected with a balancing weight 406.

Specifically, the method comprises the following steps: the balancing weight 406 can make the whole center of gravity of connecting rod 401 offset upwards to make the whole center of gravity of connecting rod 401 be in below the minimum height of flabellum 2, thereby blade arc limit in the flabellum 2 is when producing thrust to connecting rod 401, and thrust can be more smooth promote connecting rod 401.

The threaded post 504 has a diameter greater than the diameter of the attachment post 5.

Specifically, the method comprises the following steps: the support ring 507 supports the limit ring 505, the connecting column 5 and the fan blades 2 can be supported, and then the pushing strip 503 has a clamping effect on the limit strip 501 in the horizontal direction, so that the output shaft of the driving motor 101 can drive the connecting column 5 to rotate, the connecting column 5 drives the limit strip 501 to rotate through the pushing strip 503, and the fan blades 2 can slowly rotate;

it can be understood that the fan blade 2 is located above the output shaft of the driving motor 101, and if there is no supporting effect of the supporting ring 507, the whole weight of the fan blade 2 presses on the output shaft of the driving motor 101, which results in the power of the driving motor 101 being increased, and in severe cases, the output shaft of the driving motor 101 being broken;

it is worth noting that the diameter of the connecting column 5 is smaller than the diameter of the threaded column 504, and is also smaller than the diameter of the connecting shaft 201, so that a space for the first probe 404 to enter is formed between the outer peripheral wall of the connecting shaft 201 and the outer peripheral wall of the connecting column 5, and referring to fig. 7, before the connecting rod 401 abuts against the outer peripheral wall of the connecting shaft 201, the first probe 404 can normally detect height data of the fan blades 2.

the detection assembly can detect a plurality of blades in the fan blade 2 while independently detecting a single blade to obtain a plurality of groups of data, so that the data of the plurality of blades are compared, the quality parameters of the blades are confirmed, and the detection efficiency of the fan blade 2 is improved.
