Problems solved by technology
However, the structural rigidity of the inspection tool is poor, and the tool needs to be manually rotated during the inspection process, which cannot fit the shape of the intake port; the template and the positioning ring will be heated and deformed during the welding process, and the accurate relative position cannot be maintained, resulting in low positioning accuracy; The existence of gaps needs to be observed by quality inspectors with naked eyes, and inspectors with rich experience are required to operate. Even so, the accuracy of gap observation with naked eyes is still difficult to guarantee

The invention discloses an air blower diffuser profile inspection tool. The air blower diffuser profile inspection tool comprises a tool body and a supporting frame detachably connected with the toolbody. The tool body comprises a base, a curved surface inspection part integrally formed with the base and extending upwards from the base and a neck formed in the curved surface inspection part, theside face of the curved surface inspection part is a standard curved surface consistent with the bending direction of the air inlet channel molded line of the diffuser, and the supporting frame is clamped into the neck to be connected with the tool body. The supporting frame comprises a supporting rod clamped into the neck, a pressing plate arranged at the bottom of the base, a locking screw usedfor connecting the supporting rod and the pressing plate and a handle connected with the tail end of the locking screw, and the tool body can be driven to rotate by rotating the handle.
Description
technical field [0001] The invention relates to the technical field of blower detection, in particular to a blower diffuser profile inspection tool. Background technique [0002] The impeller of the blower is installed inside the diffuser. The profile of the fan inlet is used to control the gap between the inlet and the impeller. The gap has an important impact on the performance of the blower. If the gap is too large, the efficiency of the blower will be reduced. If the gap is too small, the impeller will The operation is blocked, and even the impeller blades are worn, reducing the life of the impeller. The diffuser is installed on the outside of the air flow channel, and the cylindrical boss at the bottom of the diffuser goes deep into the air flow channel, and the outer circle size is the matching size. If the size of the outer circle at the bottom of the diffuser is too large, the diffuser cannot be installed into the air flow channel, and if it is too small, there will...
