Description

Technical Field

[0001] The invention belongs to the technical field of motor testing, and in particular relates to a complete motor testing device. Background Art

[0002] The motor complete machine test device is a test device used to comprehensively test various performance indicators of the motor;

[0003] Conventionally, when inspecting the inner circle of a motor, a handheld instrument is inserted into the inner circle of the motor manually, and then the inner circle is scanned and inspected by a scanner. However, it is difficult to keep the scanner at the same distance from each point of the inner circle manually, and the range of a single scan is limited, which requires multiple scans, and the position needs to be adjusted for each scan, which leads to low inspection efficiency.

[0004] In view of this, a whole motor testing device is proposed. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] In view of the following technical problems in the prior art: conventionally, when inspecting the inside of the motor circle, a handheld instrument is manually inserted into the inside of the motor circle, and then the inner circle is scanned and inspected by a scanner. However, it is difficult to manually keep the scanner at the same distance from each point of the inner circle, and the range of a single scan is limited, which requires multiple scans, and the position needs to be adjusted for each scan, which leads to low detection efficiency.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a motor whole machine testing device, comprising a bearing platform, a detection platform and a rotating platform;

[0008] The detection platform is telescopically installed below the bearing platform, and the detection platform and the bearing platform are distributed in parallel. A through hole is opened at the center of the bearing platform, wherein the through hole is used for the telescopic movement of the rotating platform and the scanning probe, so as to facilitate the testing of the inside of the motor body. A limiting groove is milled on the periphery of the bearing platform near the through hole, and the motor body is placed on the limiting groove;

[0009] A shaft sleeve is installed at the center of the detection platform, a transmission shaft is hingedly connected to the shaft sleeve and the middle of the detection platform, a rotating platform is arranged on the top periphery of the transmission shaft, a scanning probe is installed on the periphery of the rotating platform, wherein the scanning probe is used to scan and detect the inner edge of the motor body;

[0010] A linkage structure is arranged at the edge of the bearing platform.

[0011] As an optimal technical solution for a complete motor testing device, a guide column and a cylinder are installed on the supporting platform. The output end of the guide column passes through the supporting platform and is connected to the testing platform, so that the testing platform can be controlled to perform telescopic movement to detect different positions in the motor body. The cylinder and the supporting platform are in a telescopic connection relationship, and the bottom end of the cylinder is fixedly connected to the testing platform. Under the action of the cylinder, a stable guiding effect is provided for the movement of the testing platform.

When the transmission plate moves in telescopic motion, the transmission wheel can rotate on its own due to the meshing, and under the action of the transmission shaft and the rotating table, the scanning probe can comprehensively scan and detect the inner edge of the motor body.

[0014] As an optimal technical solution for a motor whole machine testing device, a vertical plate is installed on the back of the test platform, and a connecting rod is hinged between the bottom end of the vertical plate and the upper surface of the transmission plate. When the vertical plate is lifted, the transmission plate can telescopically move on the guide shaft through the connecting rod.
