Description

Technical Field

[0001] The utility model relates to the technical field of vibration motors, in particular to a vibration motor which is easy to install stably. Background Art

[0002] A vibration motor is an electric motor that combines the principles of electromagnetic force and mechanical vibration. The main structure of this device includes a fixed iron core, a coil wound with copper wire, and a rotatable eccentric wheel. When current passes through the coil, a rotating magnetic field is generated, which causes the eccentric wheel to be unbalanced, thereby generating vibration. By adjusting the magnitude and frequency of the current, the vibration amplitude and frequency of the vibration motor can be controlled. Vibration motors are widely used in many industries, such as coal, metallurgy, building materials, chemicals, etc., for operations such as material transportation, screening, and sorting. Their characteristics include large amplitude, adjustable vibration frequency, low noise, and long service life. The working principle of the vibration motor is to drive the eccentric block through the rotation of the motor, which in turn causes the bearing to vibrate eccentrically to achieve the vibration function.

[0003] When some existing vibration motors are in use, their base structures are only fixed to the equipment by bolts. Although rubber pads are provided to improve stability, the vibration generated when the vibration motor is working may still cause the bolts to loosen, thereby causing the vibration motor to deviate.

[0004] For example, a vibration motor with a stable base is disclosed in the announcement number CN220401559U. The patent makes the vibration motor stably installed by providing a main body, a fixed block, a base body and a rubber pad, and can reduce the wear between the vibration motor and the equipment. A fixed block is provided at the bottom of the main body, and a base body is provided at the bottom of the fixed block. The fixed block and the base body are both made of metal. The vibration motor base body is directly installed on the equipment, which can easily cause friction between metals during vibration, causing wear of the base body and easy loosening of the bolts. Therefore, a rubber pad is provided at the bottom of the base body. The rubber pad has a certain elasticity, which can avoid wear between the motor and the equipment, and can also avoid loosening of the bolts, so that the vibration motor can be stably installed.

[0005] This patent has a rubber pad at the bottom of the base body. Although the rubber pad has the effect of isolating friction and absorbing shock, it cannot completely isolate the vibration generated when the vibration motor is working. The bolts may still loosen due to vibration, which will cause the vibration motor to shift.

[0006] Therefore, it is necessary to invent a vibration motor that is easy to install stably to solve the above problems. Utility Model Content

[0010] Preferably, the connecting column is a variable diameter structure, and the bottom diameter of the connecting column is larger than the top diameter of the connecting column.

[0011] When the limiting disc is lifted, the bottom end of the connecting column will not be separated from the inside of the lifting slot.

[0012] Preferably, the number of the side through holes and the number of the limiting slots are both three, and the three side through holes and the three limiting slots are alternately arranged.

[0013] The angle between the side through hole and the limit card slot is 60 degrees. After the limit disc is lifted, it can be rotated to facilitate the limit card block to switch between the side through hole and the limit card slot.

Side through holes 7 are provided on the side walls of the main through holes 6. A limit slot 8 is provided on the top edge of the main through hole 6. The top four corners of the fixing plate 5 are fixedly connected with fixing columns 9. A lifting slot 10 is provided inside the fixing column 9. A connecting column 11 is slidably connected inside the lifting groove 10, and the connecting column 11 can rotate inside the lifting groove 10. The top of the connecting column 11 penetrates the lifting groove 10 and extends to the outside of the fixed column 9. The top of the connecting column 11 is fixedly connected to a limiting disc 12. The diameter of the limiting disc 12 is equal to the diameter of the fixed column 9. The outer edge of the limiting disc 12 is fixedly connected to a limiting block 13. The limiting disc 12 and the fixed column 9 are arranged through the main through hole 6, and the limiting block 13 is arranged through the side through hole 7. The limiting block 13 matches the limiting slot 8.

[0036] In one aspect of the present embodiment, the connecting column 11 is a variable diameter structure, the bottom end diameter of the connecting column 11 is larger than the top end diameter of the connecting column 11, the number of side through holes 7 and limit slots 8 are both set to three, the three side through holes 7 and the three limit slots 8 are staggered, a mounting groove 14 is opened on the surface of the bottom plate 4, a screw hole 15 is opened on the surface of the fixing plate 5, a bolt 16 is penetrated inside the mounting groove 14, and the bottom end of the bolt 16 is threadedly connected to the screw hole 15, a rubber pad 17 is provided between the fixing plate 5 and the bottom plate 4, the rubber pad 17 is fixedly connected to the top of the fixing plate 5, a lifting platform 18 is fixedly connected to the middle of the top of the bottom plate 4, the top of the lifting platform 18 is welded and fixed to the bottom of the motor body 1, and reinforcing ribs 19 are fixedly connected on both sides of the lifting platform 18, the top of the reinforcing rib 19 is welded and fixed to the bottom of the motor body 1, and the bottom of the reinforcing rib 19 is welded and fixed to the top of the bottom plate 4, and the four corners of the edge of the fixing plate 5 are fixedly connected to welding feet 20.

[0037] Working principle of this utility model:

[0038] Refer to the instruction manual Figure 1-6 When using the utility model, first place the limiting fixing mechanism 3 on the equipment, weld the welding foot plate 20 to the equipment, and install the fixing plate 5.
