Description

Technical Field

[0001] The utility model relates to the technical field of fixed tooling equipment, in particular to a fixed tooling for processing a vibration motor. Background Art

[0002] The vibration motor has a set of adjustable eccentric blocks installed at both ends of the rotor shaft, and the centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks is used to obtain the exciting force. The vibration motor has a wide vibration frequency range. Only when the exciting force and power are properly matched can the mechanical noise be reduced. There are six types of vibration motors, including those classified by starting and running mode and those classified by running speed. During the processing, it is necessary to support a variety of vibration motor workpieces on the processing equipment and tighten them through tooling restrictions so that the corresponding workpieces are well restricted. However, it still has the following disadvantages in actual use: the fixed tooling used for vibration motor processing directly fixes the corresponding workpiece on the corresponding processing equipment. When performing the corresponding processing, the restriction applicability of workpieces with different diameters is poor, and the restriction of workpieces with different diameters is inconvenient. When different products need to be replaced, it is usually necessary to remove the entire fixed tooling, which is troublesome, time-consuming and labor-intensive. Utility Model Content
