Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings so that the technical solutions of the present invention can be more clearly understood.

The utility model discloses balancing piece automated inspection frock on BLDC rotor, the automated inspection of mainly used rotor middle and upper balancing piece in the assembling process detects whether the through-hole meets the requirements on the balancing piece to guarantee that the high efficiency of follow-up equipment goes on.

The specific structure is as shown in fig. 1-4, and comprises a workbench 1 and a placing table 2 fixedly mounted on the upper surface of the workbench 1, wherein the workbench 1 is correspondingly arranged at the end part of a vibration disc and used for receiving an upper balance block conveyed from the vibration disc, a placing groove 201 for placing the balance block is integrally arranged on the placing table 2, and the lower bottom surface of the placing groove 201 and the workbench 1 are provided with detection holes 3 corresponding to through holes of the upper balance block; in order to make the upper balance weight on the vibration plate enter the placing groove 201 smoothly, a notch 202 for the upper balance weight to pass through is arranged on one side of the placing groove 201 facing the conveying belt.

Continuing to refer to fig. 1-4, in order to realize the quick detection of the quality of the through hole of the upper balance block, a through hole detection mechanism of the balance block is arranged on the lower surface of the workbench 1, the through hole detection mechanism of the balance block comprises a positioning pin 4 of the balance block and a positioning pin driving mechanism, the positioning pin 4 of the balance block is correspondingly arranged under the detection hole 3, and in order to realize the one-time detection, the number of the detection hole 3 and the positioning pin 4 of the balance block corresponds to the number of the through holes of the upper balance block one by one. The positioning pin driving mechanism comprises a positioning pin mounting plate 5 and a cylinder 6 mounted below the workbench 1 through a cylinder mounting plate 7, the end part of a cylinder rod of the cylinder 6 is fixedly connected with the positioning pin mounting plate 5, and a balance block positioning pin 4 is vertically mounted on the positioning pin mounting plate 5.
