Embodiment Construction

[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0014] like figure 1 As shown, a checker for detecting the beating of fan blades includes a supporting base 1 for supporting. The supporting base 1 is provided with a shaft sleeve 11, and a rotating shaft 2 is arranged inside the shaft sleeve 11. The rotating shaft 2 is installed through a bearing 3. In the shaft sleeve 11, one end of the rotating shaft 2 extends into the shaft sleeve, and the other end 21 of the rotating shaft 2 extends to the upper end of the shaft sleeve 11 for connecting the fan blades. There is a dial indicator on the frame for detecting the beating rate of the fan blades. The support base 1 is in the shape of a disc. The bushing 11 is located in the middle of the upper part of the support base 1 and is integrated with the ...

Abstract

The invention discloses a tool for detecting runout of fan blades and relates to the technical field of measuring devices. The tool for detecting runout of the fan blades comprises a support base used for supporting. A shaft bushing is arranged on the support base, a rotating shaft is arranged in the shaft bushing through a bearing, one end of the rotating shaft extends into the shaft bushing, and the other end of the rotating shaft extends to the upper end of the shaft bushing and is used for connecting the fan blades. A dial indicator holder is arranged on one side of the support base, and a dial indicator used for detecting runout frequency of the fan blades is arranged on the dial indicator holder. The tool for detecting runout of the fan blades is simple in structure and convenient to use, and can detect quality of the fan blades by fixing the fan blades at the upper end of the rotating shaft, rotating the fan blades and measuring runout frequency of the fan blades by the dial indicator, detecting difficulty is greatly reduced, time and labor are saved, and detecting efficiency is evidently improved.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to a checker for detecting the beating of fan blades. Background technique [0002] Fan products are commonly used in industrial equipment and daily life, especially on various radiators. In the production process, the fan needs to be tested for jumping, that is, to detect the balance of the fan during rotation. At present, the conventional measuring tool is to use a three-coordinate measuring instrument for measurement. Due to the complicated operation of the three-coordinate measuring instrument, it is difficult for ordinary technicians to use It is very inconvenient, and the measurement needs to be carried out one by one, which takes a long time and improves the work efficiency. Patent No. 201020512521.2 discloses a checker for measuring fan beating. The checker includes a base, a rotating part mounted on the base to drive the fan to rotate, and a standard measuring pi...
