Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

With reference to the attached drawings 1-5, the device for testing the welding of the motor shaft blade comprises a first sleeve 1 matched with a motor shaft, wherein a second sleeve 2 is arranged outside the first sleeve 1; a rotating structure is arranged between the first sleeve 1 and the second sleeve 2; the outside of second sleeve 2 be provided with guide way 3, the guide way 3 fit in is provided with slider 4, the one end of connecting rod 5 is connected fixedly with slider 4, the other end of connecting rod 5 is provided with inspection board 6.

Specifically, the rotating structure comprises a circumferential groove a7 formed in the outer surface of the first sleeve 1, a circumferential groove b8 is formed in the position, corresponding to the circumferential groove a7, of the inner surface of the second sleeve 2, and a ball 9 is arranged between the circumferential groove a7 and the circumferential groove b 8. The rotation of the second sleeve can be realized; the second sleeve drives the inspection plate to rotate, so that the position detection of the plurality of blades is realized; the annular grooves a7 and the annular grooves b8 are symmetrically arranged at the upper end and the lower end of the first sleeve 1 and the second sleeve 2 respectively, so that the stability of the rotating structure is better; the detection efficiency is improved; the section of the guide groove 3 is I-shaped, the sliding block 4 comprises two oppositely arranged convex blocks 4-1, and the sliding block 4 is matched with the guide groove 3 through the convex blocks 4-1; the up-and-down sliding of the sliding block is realized, so that the inspection plate is driven to move up and down, and the position of the inspection plate is convenient to adjust. And the top and the bottom of the guide groove 3 are provided with baffle plates 10. The inspection plate 6 is arranged as an arc-shaped plate, the included angle of the arc-shaped plate is theta, and the included angle is the same as the installation requirement angle of two adjacent blades.

When the device is specifically implemented, the utility model is sleeved on a motor shaft of a workpiece to be detected, and in a free state, a check plate of the device is in the same plane with the blade; therefore, when the device is used for detection, the sliding block needs to be pulled upwards to enable the inspection plate to move upwards in a horizontal mode, and meanwhile, the second sleeve is rotated to enable the inspection plate to be just arranged between adjacent blades; if the two side edges of the inspection board are attached to the side edges of the adjacent blades, the position degree of the blade meets the requirement; if a gap is formed between the two side edges of the inspection plate and the side edges of the adjacent blades or the gap is not uniform, the position degree of the blade does not meet the requirement and needs to be repaired.
