[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. The fan blades are an important component of the fan. The fan blades are driven by a motor and rotate to generate wind.

[0003] Large size fan blades (greater than or equal to 57 inches) are generally sheet-shaped (such as Figure 1 As shown in A), after the fan blades are processed, the dimensions of each part of the fan blades need to be measured, such as the angle difference between the two ends of the fan blades, the length of the fan blades, the data of each part of the fan blade body, etc., to ensure that the fan blades meet the production and use requirements before being put into use;

[0004] The existing technology for measuring the length of fan blades mainly relies on workers to use handheld measuring tools to measure various parameters of the fan blades. This not only has low measurement efficiency but also has large measurement errors.

[0005] In view of this, there is an urgent need for a fan blade measuring tool to solve the above problems. Summary of the Invention

[0006] In order to help solve the problems existing in the prior art, the present application provides a fan blade measuring tool, which adopts the following technical solution: comprising: a load-bearing tool and a measuring tool, the load-bearing tool comprising a fan blade head support member and a fan blade tail support member, the top end of the fan blade head support member is provided with a first load-bearing surface adapted to the fan blade head ring side, and the top end of the fan blade tail support member is provided with a second load-bearing surface adapted to the fan blade tail ring side;

[0007] The measuring fixture includes a bracket and a measuring head. The measuring head is arranged on the bracket and is used to measure the fan blade body at the support fixture from top to bottom.

[0008] It is further characterized in that

[0009] It also includes an operating platform, and the carrying tooling and the measuring tooling are both arranged on the operating platform.

[0010] The measuring tool further comprises a sliding base, a slide rail is provided on the operating platform, the sliding base is clamped on the slide rail, and the bracket is provided on the sliding base.

[0011] The bracket comprises a vertical rod and a horizontal rod, the vertical rod is vertically arranged on the sliding base, the horizontal rod is horizontally arranged on the vertical rod, and the measuring head is arranged on the horizontal rod.

[0012] The cross bar is slidably arranged on the vertical bar.

[0013] A digital display screen is provided on the cross bar.

[0014] The load-bearing tooling also includes a blade head limiting column, which is arranged on a side of the blade head support member away from the blade tail support member.

[0015] A sliding rod is provided through the blade head limiting column, and the sliding rod extends from the blade head support to one side of the blade tail support. A limiting plate is provided at one end of the sliding rod close to the blade tail support, and the limiting plate is adapted to the limiting hole on the end face of the blade head.

[0016] The fan blade tail support is provided with a fan blade tail positioning plate on a side of the second bearing surface away from the fan blade head support.

[0017] There are two blade head support members, and the top ends of the two blade head support members are both provided with a first bearing surface. The top ends of the two blade head support members are both provided with a blade head positioning plate on one side away from each other.

[0018] The above structure of the present application can achieve the following beneficial effects:

[0019] When measuring the fan blade, the head and tail of the fan blade are placed on the fan blade head support and the fan blade tail support respectively. Since the first bearing surface and the second bearing surface are respectively adapted to the head and tail ring sides of the standard fan blade, if the fan blade head or tail placed on the fan blade head support and the fan blade tail support cannot adapt to the corresponding bearing surface, it means that the fan blade has defects and does not meet the specifications. The fan blade body at the bearing tooling is measured from top to bottom by the measuring head to obtain the parameters of the fan blade body. The parameters are compared with the standard parameters to determine whether the fan blade body meets the specification requirements.

In this way, when measuring the fan blade, the head and tail of the fan blade are respectively placed on the fan blade head support 1 and the fan blade tail support 2 (such as Figure 1 and Figure 3As shown), since the first bearing surface 11 and the second bearing surface 21 are respectively adapted to the head and tail ring sides of the standard fan blade, if the head or tail of the fan blade placed on the fan blade head support 1 and the fan blade tail support 2 cannot be adapted to the corresponding bearing surfaces (the first bearing surface 11 and the second bearing surface 21), it means that the fan blade is defective and does not meet the specifications, and the fan blade body at the bearing fixture is measured from top to bottom by the measuring head 4 to obtain the parameters of the fan blade body, and the parameters are compared with the standard parameters to determine whether the fan blade body meets the specification requirements. In this way, the measurement of multiple parts of the fan blade is completed, which is convenient and fast, and the error is small.

[0029] like Figure 2 As shown, this embodiment further includes an operating platform 5, on which both the carrying tooling and the measuring tooling are arranged, thereby completing the integration of the carrying tooling and the measuring tooling, and facilitating positioning operations.

[0030] like Figure 2 As shown, the measuring tool also includes a sliding base 6, a slide rail 51 is provided on the operating platform 5, the sliding base 6 is clamped on the slide rail 51, and the bracket is provided on the sliding base 6, so that the measuring head can be moved in the length direction of the fan blade to measure different positions of the fan blade body, and the bracket includes a vertical rod 7 and a cross bar 3, the vertical rod 7 is vertically provided on the sliding base 6, the cross bar 3 is horizontally provided on the vertical rod 7, the measuring head 4 is provided on the cross bar 3, and the cross bar 3 is slidingly provided on the vertical rod 7, so that the position of the measuring head 4 is adjusted by sliding the cross bar 3 on the vertical rod 7 (the sliding direction includes the vertical direction and the horizontal direction), and in order to facilitate the observation of the measurement results, a digital display screen 31 is provided on the cross bar 3, and the measurement results can be observed conveniently and in real time through the digital display screen 31.
