Vacuum adsorption device

Abstract

The invention relates to a vacuum adsorption device, which is used for assembling two magnetic steel tiles in a motor shell with a magnetic steel tile positioning block. The device comprises a mounting bottom plate, a placement column, a second vacuum pipeline, a third vacuum pipeline, a first vacuum pipeline, a right vacuum meter and a left vacuum meter, wherein the placement column is fixedly connected to the bottom surface of the mounting bottom plate; the outer edge of the placement column is fixedly connected with the magnetic steel circumferential positioning block and is also provided with a first square groove and a second square groove which are symmetrically distributed on the two sides of the magnetic steel circumferential positioning block; the right vacuum meter is communicated with the second vacuum pipeline and the third vacuum pipeline; and the left vacuum meter is connected and communicated with the first vacuum pipeline. The vacuum adsorption device has the advantages of rational, compact and simple structure, easiness for manufacturing, low cost and convenience for use; and by replacing the placement columns of different diameters, vacuum adsorption of the various magnetic steel tiles of different specifications and automatic detection for existence and correctness of the specification of the magnetic steel tiles before assembly can be realized.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a vacuum adsorption device for assembling magnetic steel tiles in a DC motor casing. Background technique [0002] During the assembly process of the permanent magnet DC motor, two magnetic steel tiles are usually assembled in place in the electrode housing first, and then magnetized. However, the existing fixtures cannot ensure that the magnetic steel tiles are reliably and accurately clamped or adsorbed before being assembled to the motor housing, nor can they ensure that the circumferential positions of the two magnetic steel tiles are consistent; After finishing the magnetic steel tiles, manual adjustment is required, which is not only time-consuming and laborious, but also easy to damage the magnetic steel tiles, thus affecting the overall quality of the motor. In view of the foregoing, it is currently necessary to improve the jig for assembling the magnetic steel tiles in the DC motor ...
