Problems solved by technology

[0002] At present, most existing vibration motor excitation force adjustment structures use rivets to fix aluminum signs with scales on the active eccentric block. This structure requires drilling rivet holes on the active eccentric block, and the tightening of the active and driven eccentric blocks The holes must be processed manually after the mold is opened, which increases the cost of labor processing. Although there are also flanges on the aluminum sign to prevent the customer from reversely adjusting the driven eccentric block, but because the strength is not strong and the customer will not Very important, unable to play its due role

Abstract

The invention discloses an adjustable eccentric block device which comprises a spindle. Eccentric blocks are disposed at two ends of the spindle. Each eccentric block is detachably connected with the spindle. Each eccentric block includes a master eccentric block and a slave eccentric block, the master eccentric block and the slave eccentric block are symmetrically disposed on the spindle, and a dial is disposed on the master eccentric block. The adjustable eccentric block device has the advantages that the master eccentric blocks and the slave eccentric blocks are symmetrically distributed on the spindle, the vibration frequency of a vibration motor is adjusted by adjusting the slave eccentric blocks, the vibration frequency of the vibration motor can be displayed by the dial on the master eccentric block, vibration motor assembling is facilitated, the vibration frequency of the vibration motor can be adjusted conveniently, assembling efficiency is increased, and manpower cost is lowered to a certain extent.

Description

technical field [0001] The invention relates to an installation tool, more specifically, the invention relates to an adjustable eccentric mass device. Background technique [0002] At present, most existing vibration motor excitation force adjustment structures use rivets to fix aluminum signs with scales on the active eccentric block. This structure requires drilling rivet holes on the active eccentric block, and the tightening of the active and driven eccentric blocks The holes must be processed manually after the mold is opened, which increases the cost of labor processing. Although there are also flanges on the aluminum sign to prevent the customer from reversely adjusting the driven eccentric block, but because the strength is not strong and the customer will not It is very important and cannot play its due role. Contents of the invention [0003] The purpose of the present invention is to solve the existing above-mentioned problems and provide an adjustable eccentri...
