[0002] The excitation coil of the vibration table needs to be processed multiple times during the production process.

Since the excitation coil of the vibration table is composed of multiple turns of coils wound together, it is easy to be subjected to uneven force during the positioning process, causing the position of some coils to move, thereby damaging the overall structure of the excitation coil of the vibration table.

[0041] The working principle of the utility model is as follows: before using a vibrating table excitation coil limiting and fixing device, install the vibrating table excitation coil limiting and fixing device on the production line; when using a vibrating table excitation coil limiting and fixing device: the external transport mechanism transports the vibrating table excitation coil that needs to be positioned to the base 1, during this process, a plurality of positioning members 5 are fitted into the interior of the vibrating table excitation coil, at which time the vibrating table excitation coil is initially positioned, and then the external control system ventilates the middle member 7 through the air pipe joint 8, during this process, the air pressure in the cavity of the middle member 7 and the connecting member 6 increases, thereby stretching a plurality of telescopic tubes of the connecting member 6, during this process, the connecting member 6 pushes the positioning member 5 to move in the limiting groove 3, during this process, a plurality of positioning members 5 make centrifugal motion to approach the inner wall of the vibrating table excitation coil, and then press against the inside of the vibrating table excitation coil, when the positioning member 5 reaches the limit position, the extension tube of the connecting member 6 is in the longest extension state, and then the pushing member 11 starts to work under the control of the external control system, and then During this process, the push rod of the pushing member 11 extends to drive the driving member 12 to move between the multiple positioning members 5. During this process, the side of the positioning member 5 contacts the positioning member 5. During this process, the side of the driving member 12 contacts the upper part of the positioning member 5, and then under the drive of the first surface, the upper part of the positioning member 5 performs partial centrifugal movement. When the second surface of the driving member 12 contacts the upper part of the positioning member 5, the positioning member 5 stops working and moving. The positioning member 5 is in a vertical state at this time. At this time, the excitation coil of the vibration table is in a completely positioned state, and the external mechanism begins to process the excitation coil of the vibration table. When the processing is completed, under the control of the external control system, the pushing member 11 first drives the driving member 12 to reset, and then the external control system evacuates the connecting member 6 through the air pipe joint 8. During this process, driven by the connecting member 6, the positioning member 5 slides in the limiting groove 3 to move toward the middle member 7. When the positioning member 5 is reset, the external transport mechanism moves the processed excitation coil of the vibration table away, and places a new vertical magnetic coil of the vibration table on the base 1, and repeats the above process until the work is completed.
