Problems solved by technology

[0007] The above-mentioned variable force wheel is controlled by air pressure and needs to be equipped with a clean air source; when using a cylinder, there are problems such as air leakage and oil leakage; due to the use of air pressure control, the sealing requirements are high, and the processing accuracy and roughness of the cylinder and plunger high degree requirements
This increases processing difficulty and manufacturing cost, and these are the deficiencies of the cylinder-cylindrical piston variable force wheel

Embodiment 1

[0035] refer to figure 1 , the vibration motor 3 proposed by the present invention uses a fan-shaped eccentric block force converter and a vibration motor 3, including:

[0036] A connecting sleeve 5 is connected circumferentially with the shaft end of the main shaft of the vibration motor 3 by a key, and rotates synchronously with the main shaft of the vibration motor 3;

[0037] A fixed eccentric block 2 and a movable eccentric block 1 are sleeved on the connecting sleeve 5, the fixed eccentric block 2 is fixedly arranged on the side of the connecting sleeve 5 close to the vibration motor 3, and the movable eccentric The block 1 is located on the side of the fixed eccentric block 2 away from the vibration motor 3 and is in clearance fit with the connecting sleeve 5;

[0038] A sliding core 6 is arranged in the connecting sleeve 5, the sliding core 6 rotates synchronously with the connecting sleeve 5, and can be axially displaced relative to the connecting sleeve 5; specific...

Embodiment 2

[0052] refer to figure 2 The vibration motor proposed by the present invention includes the force converter 20 as described in Embodiment 1, and the force converter 20 is symmetrically arranged on both sides of the vibration motor 3 . The pull shaft sleeve 11 of the torque converter 20 controls its rotation through the handle 12 fixedly connected with it. The handle 12 can be fixed on the supporting circular plate 13 by a locking bolt to fix the eccentricity. The locking bolt can keep the movable eccentric wheel 1 Set position, until it is adjusted again, then loosen the locking bolt. A dial for determining the angle of rotation of the handle 12 is also included. When the pulling bearing 11 on one side is adjusted to a suitable angle, the dial will display the rotation angle of the handle 12, and then the pulling bearing 11 on the other side can be directly rotated to the angle.

Embodiment 3

[0054] refer to image 3 , The vibration motor proposed by the present invention includes the force converter 20 as described in Embodiment 1, and the force converter 20 is symmetrically arranged at both ends of the main shaft of the vibration motor 3 . The rotation of the pulling bushing 11 of the force converter 20 is controlled by a manual torque converter 18 , and the manual torque converter is connected with the pulling bushing through a flexible shaft 19 . The pull bushings on both sides of the vibration motor are adjusted by direct synchronization with a manual torque converter.

Abstract

The invention discloses a fan-shaped eccentric block force converter for a vibration motor and the vibration motor. The fan-shaped eccentric block force converter comprises a connecting sleeve, a fixed eccentric block, a movable eccentric block, a sliding core, a shifting shaft sleeve and a driving assembly for controlling the axial displacement of the sliding core. According to the fan-shaped eccentric block force converter, the combined eccentric distance of the eccentric blocks is changed through the force converter, the exciting force is changed, and the technical effect that the exciting force is continuously and steplessly adjusted within the range of 0-100% in the rotating state of the vibration motor is achieved; zero-amplitude starting and stopping can be achieved, and excessive amplitude caused by the fact that equipment passes through a resonance area is avoided. Meanwhile, the force converter can be manually controlled and adjusted or electrically controlled and adjusted, an air source device and an air cylinder do not need to be additionally arranged, and the problems of air leakage, oil leakage and the like which pollute the environment are solved. As the force converter does not need to be sealed, the requirements for parts machining precision and roughness are not high, and the advantages of low cost and simple field operation are achieved.

Description

technical field [0001] The invention relates to the technical field of vibration motors, in particular to a fan-shaped eccentric block force converter for a vibration motor and a vibration motor. Background technique [0002] At present, the excitation force adjustment of the vibration motor is to open the protective cover when the vibration motor stops running, loosen the fastening bolts with a wrench, move the movable eccentric block to a roughly suitable position, tighten the bolts, and then put the protective cover Only when the cover is installed can the vibration motor be started to see the adjustment effect. Because it is not adjusted in real time online, there are problems of under-adjustment or over-adjustment, and repeated adjustments are required, which is very troublesome. The key is that it is difficult to adjust to a suitable state after repeated several times. The success rate of debugging is very low. [0003] At the same time, some industries, such as the...
