Description

Technical Field

[0001] This utility model belongs to the field of vibration motor technology, and in particular relates to a vibration motor eccentric block adjustment disc mechanism. Background Technology

[0002] The eccentric block adjusting disc mechanism for vibratory motors is a device used to adjust the excitation force of a vibratory motor. The eccentric block is one of the core components of the vibratory motor, located on one side of the motor shaft, usually on the rotor. It generates centrifugal force through rotation to achieve vibration. This mechanism is widely used in vibratory equipment requiring adjustable excitation force, such as vibrating screens, vibrating feeders, and vibrating conveyors. By adjusting the position or angle of the eccentric block, the excitation force of the vibratory motor can be changed, thus meeting the needs under different working conditions. However, it still has the following drawbacks in practical use:

[0003] When the eccentric block adjustment disc mechanism of the vibrating motor is in operation, the disc mechanism is installed in a suitable position. When the eccentric block is rotated during operation, the rotating structure that mounts the eccentric block can rotate. However, the operator needs to manually support it to prevent the eccentric block from rotating with the disc mechanism, which makes adjustment inconvenient.

[0004] Secondly, in order to obtain different excitation forces, the phase of the two vibration-driven eccentric blocks needs to be changed during the adjustment of the eccentric block adjustment disc mechanism of the vibration motor. However, if only one eccentric block is rotated and adjusted during the phase adjustment of the two eccentric blocks, the phase adjustment accuracy is insufficient. Utility Model Content

[0005] The purpose of this utility model is to provide a vibration motor eccentric block adjustment disc mechanism. By setting up a double-headed motor, eccentric block, fixed chamber and mounting block, it solves the problems that the vibration motor eccentric block adjustment disc mechanism requires manual support and adjustment by the operator when rotating the eccentric block, which is inconvenient and the phase adjustment accuracy is insufficient.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a vibration motor eccentric block adjustment disc mechanism, comprising a dual-head motor, an eccentric block, a fixed chamber, and a mounting block. Both output ends of the dual-head motor are fixed with output shafts. A turntable is fixed to the end of each output shaft furthest from the dual-head motor. An eccentric block is centrally located at the end of each turntable furthest from the output shaft. Limiting sleeves are fixed in a circular array around the turntable. Fixed chambers are fixed to both ends of the dual-head motor. A mounting block is fixed to the upper part of each fixed chamber. A limiting screw is threaded through the mounting block. The limiting screw is movably connected to a limiting sleeve on the circumference of the turntable. A hexagonal insertion hole is provided at the end of the limiting screw furthest from the limiting sleeve. During operation, the dual-head motor drives the output shafts to rotate, causing the turntable to rotate. Simultaneously, the eccentric block rotates, generating a vibration force. The fixed chamber seals the turntable and eccentric block within it, providing a closed enclosure for the eccentric block. The limiting screw, threaded through the mounting block, is inserted into the limiting sleeve to fix the relative position of the turntable and the fixed chamber.

[0008] Furthermore, a rotating block is fixed at the center of the end of the turntable away from the output shaft. Threaded holes are arranged in a circular array inside the turntable outside the rotating block. Each threaded hole has a rounded corner at the edge away from the output shaft. The rotating block on the turntable is movably connected to an eccentric block.

[0009] Furthermore, the end of the eccentric block near the turntable is movably connected to the rotating block, and a mounting bolt is inserted through the upper part of the eccentric block. The mounting bolt is threaded into a threaded hole, so that the eccentric block is connected and fixed on the turntable during operation.

[0010] Furthermore, a support block is fixed to the lower periphery of the fixed chamber, the output shaft passes through the end of the fixed chamber, and the support block on the fixed chamber supports the fixed chamber on the equipment that needs to vibrate.

[0011] Furthermore, a fixing ring is fixed at the edge of the fixed chamber away from the dual-head motor, and the end of the fixing ring away from the dual-head motor is fixed with mounting studs in a circular array, and the fixing ring on the fixed chamber is connected to the mounting studs.

[0012] Furthermore, a sealing cover is provided at the end of the fixing ring and the fixing chamber away from the dual-head motor. The mounting studs pass through the sealing cover and extend out. Each part of the mounting studs extending out of the sealing cover is threaded with a nut, and the sealing cover is installed on the fixing chamber.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of inconvenience caused by the need for manual adjustment of the eccentric block in the vibratory motor eccentric block adjustment disc mechanism. By incorporating a dual-head motor, a fixed chamber, and a mounting block, the present invention addresses this issue. To adjust the eccentric block's position, ensure the dual-head motor is powered off, unscrew the nut from the mounting stud, and remove the sealing cap from the fixed chamber. Then, rotate the turntable, aligning a limiting sleeve on the turntable's periphery with a limiting screw. Insert a hex wrench into the hexagonal socket, and rotate the limiting screw until it enters the limiting sleeve, thus restricting the position of the turntable and the fixed chamber, facilitating the adjustment of the turntable and eccentric block's position.

[0015] This invention solves the problem of insufficient phase adjustment accuracy of the eccentric block adjustment disc mechanism in a vibratory motor by setting up a dual-head motor, eccentric blocks, and a fixed chamber. After the position of the turntable is set in the fixed chamber, a hex wrench is inserted into the mounting bolt. After rotating the mounting bolt away from the threaded hole in the turntable, the eccentric blocks can be rotated, changing the phase of rotation of the two eccentric blocks. Since the phases of the two eccentric blocks can be adjusted and set mutually, the vibration phase adjustment of the entire vibratory motor is more accurate. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0027] Please see Figure 1-5 This utility model relates to a vibration motor eccentric block adjustment disc mechanism, comprising a dual-head motor 1, an eccentric block 2, a fixed chamber 3, and a mounting block 4. Both output ends of the dual-head motor 1 are fixed with output shafts 101. When the dual-head motor 1 operates, it drives the two output shafts 101 to rotate, thereby driving two turntables 102 to rotate. Each output shaft 101 has a turntable 102 fixed at its end furthest from the dual-head motor 1. As the turntables 102 rotate, they drive the eccentric blocks 2 to rotate. An eccentric block 2 is positioned at the center of the end of each turntable 102 furthest from the output shaft 101. During rotation, the eccentric blocks 2 generate excitation force through eccentric vibration. Limiting sleeves 105 are fixed in a circular array around the circumference of the turntables 102, restricting the position between the turntables 102 and the fixed chamber 3. Both ends of the dual-head motor 1... A fixed chamber 3 is fixed, in which an eccentric block 2 is placed. An installation block 4 is fixed at the upper part of the fixed chamber 3, and a limiting screw 401 is threadedly connected to the installation block 4. The limiting screw 401 is threadedly connected through the installation block 4. The limiting screw 401 is movably connected to a limiting sleeve 105 on the periphery of the turntable 102. A hexagonal insertion hole 402 is opened at the end of the limiting screw 401 away from the limiting sleeve 105. During operation, after the sealing cover 5 is opened, the turntable 102 is rotated, and the limiting sleeve 105 on the periphery of the turntable 102 is aligned with the limiting screw 401. Then, a hexagonal wrench is inserted into the hexagonal insertion hole 402, and the limiting screw 401 is rotated until it enters the limiting sleeve 105, thus limiting the position of the turntable 102 and the fixed chamber 3.

[0028] Specifically, a rotating block 103 is fixed at the center of one end of the turntable 102 away from the output shaft 101. Threaded holes 104 are arranged in a ring array inside the turntable 102 outside the rotating block 103. Each threaded hole 104 has a rounded corner at its edge away from the output shaft 101. When the turntable 102 is in operation, the rotating block 103 is connected to the eccentric block 2, and the mounting bolt 201 is threadedly connected through the threaded hole 104.

[0029] Furthermore, the end of the eccentric block 2 near the turntable 102 is movably connected to the rotating block 103. An installation bolt 201 is inserted through the upper part of the eccentric block 2. The installation bolt 201 is threaded into a threaded hole 104. By rotating the installation bolt 201, the installation bolt 201 is screwed into the threaded hole 104, and then the eccentric block 2 and the turntable 102 are installed.

[0030] The operation process of this embodiment is as follows: During operation, after the position of the turntable 102 is set in the fixed chamber 3, the hex wrench is inserted into the mounting bolt 201. After rotating the mounting bolt 201 away from the threaded hole 104 in the turntable 102, the eccentric block 2 can be rotated to change the phase of the rotation of the two eccentric blocks 2. The phases of the two eccentric blocks 2 can be adjusted and set to each other, so that the adjustment of the vibration phase of the entire vibration motor is more accurate. Specific Implementation Example 2

[0031] Please see Figure 1-7 Based on the first specific embodiment, a support block 301 is fixed to the lower part of the periphery of the fixed chamber 3, and the output shaft 101 passes through the end of the fixed chamber 3. The support block 301 on the fixed chamber 3 is supported on the mounting device of the dual-head motor 1.

[0032] Specifically, a fixing ring 302 is fixed at the edge of the fixed chamber 3 away from the dual-head motor 1. The end of the fixing ring 302 away from the dual-head motor 1 is fixed with mounting studs 303 in a ring array. The fixing chamber 3 is fixed with mounting bolts 201 through the fixing ring 302 and connected with nuts 304 through the mounting studs 303.

[0033] Furthermore, a sealing cover 5 is provided at the end of the fixing ring 302 and the fixing chamber 3 away from the dual-head motor 1. The mounting studs 303 pass through the sealing cover 5 and protrude. Each part of the mounting studs 303 protruding from the sealing cover 5 is threadedly connected to a nut 304. The sealing cover 5 covers the fixing ring 302 and is fixed to the fixing chamber 3, so that the mounting studs 303 pass through the sealing cover 5. After the nut 304 is screwed onto the sealing cover 5 and tightened, the sealing cover 5 is fixed to the fixing chamber 3.

[0034] The operation process of this embodiment is as follows: During operation, the dual-head motor 1 is first installed on the equipment that requires vibration power. At this time, after the support block 301 on the lower part of the fixed chamber 3 is supported on the equipment on which the dual-head motor 1 is installed, the dual-head motor 1 can be started to drive the output shaft 101 and drive the turntable 102 to rotate. The rotation of the turntable 102 drives the two eccentric blocks 2 to rotate, generating excitation force. When it is necessary to adjust the position of the eccentric blocks 2, ensure that the dual-head motor 1 is de-energized, unscrew the nut 304 from the mounting stud 303, and after unscrewing the nut 304, remove the sealing cover 5 from the fixed chamber 3. Then, rotate the turntable 102 and align a limiting sleeve 105 on the side of the turntable 102 with the limiting screw 401. Then, insert a hex wrench into the hexagonal socket 402 and rotate the limiting screw 401 until it enters the limiting sleeve 105, thus limiting the position of the turntable 102 and the fixed chamber 3, which facilitates the adjustment of the position of the turntable 102 and the eccentric blocks 2.
