Description

Technical Field

[0001] This application relates to the field of vibration motor technology, and in particular to a vibration motor that is easy to assemble. Background Technology

[0002] Currently, vibratory motors are widely used in industrial production for various processes such as feeding, screening, and conveying. However, traditional vibratory motors present several inconveniences during assembly. First, the motor housing is typically a one-piece structure, limiting operating space and making assembly difficult when installing the motor body and eccentric blocks. Furthermore, the motor housing and end cover are generally connected by bolts, requiring individual bolt tightening during installation, which is time-consuming and demands a high level of operator skill. In situations requiring frequent disassembly and assembly of the vibratory motor, such as equipment maintenance and component replacement, traditional assembly methods significantly increase maintenance costs and downtime, impacting production efficiency. Moreover, because vibratory motors generate significant vibrations during operation, prolonged use may cause bolt connections to loosen, leading to decreased stability between motor components, affecting normal motor operation, and potentially causing safety accidents.

[0003] To address this problem, a vibration motor that is easy to assemble has been invented. Utility Model Content

[0004] The purpose of this invention is to provide a vibration motor that is easy to assemble, in order to solve the problems of complex assembly process, time and labor-intensive process of existing vibration motors, and instability caused by loose connections during operation, thereby improving the assembly efficiency and operational stability of vibration motors.

[0005] This application provides a vibration motor that is easy to assemble, which adopts the following technical solution: it includes a motor housing, a motor body, eccentric blocks, end caps, and a quick-connect mechanism. Eccentric blocks are respectively provided at both ends of the motor body, the motor body is located inside the motor housing, and end caps are respectively provided at both ends of the motor housing. The motor housing is a split structure and is composed of two half-shells. The two half-shells are connected to each other and to the end caps through a quick-connect mechanism.

[0006] Optionally, the quick-connect mechanism includes a positioning seat, a connecting seat, and quick-connect components. The positioning seat and the connecting seat are respectively installed at one end of the two connected components. The positioning seat and the connecting seat are connected by a plurality of quick-connect components. The quick-connect components include a first positioning groove, which is formed on the periphery of the connecting seat. The positioning seat is provided with a first positioning protrusion that can be inserted into the first positioning groove. The connecting seat is provided with a second positioning groove, and the positioning seat is provided with a second positioning protrusion that can be inserted into the second positioning groove.

[0007] Optionally, the number of quick-connect components is set to two and they are evenly distributed around the periphery of the connector.

[0008] Optionally, the connecting seat has a slot, and a swingable arc-shaped clamping rod is hinged in the slot. One end of the arc-shaped clamping rod has a fixed protrusion. A slidable limiting rod is provided in the slot, and a fixed compression spring is provided on the limiting rod. The other end of the fixed compression spring is fixed in the slot. The positioning seat has a limiting groove communicating with the slot. The limiting rod can be inserted into the limiting groove. When the arc-shaped clamping rod rotates, it can push the limiting rod into the limiting groove.

[0009] Optionally, the other end of the arc-shaped clamping rod is provided with a rotatable rotating bolt, and the positioning seat is provided with a threaded hole, into which the rotating bolt can be inserted.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. Easy assembly: The motor housing adopts a split structure, consisting of two half-shells. The half-shells are connected to each other and to the end cover through a quick-connect mechanism. Compared with the traditional bolt connection method, this greatly reduces assembly time and improves assembly efficiency.

[0012] 2. Precise positioning: The positioning seat and connecting seat in the quick connection mechanism achieve precise positioning through the cooperation of the first positioning protrusion and the first positioning groove, the second positioning protrusion and the second positioning groove, which ensures the accuracy of the relative position of each component of the motor after assembly and is conducive to the stable operation of the motor.

[0013] 3. Stable connection: The arc-shaped clamping rod, limit rod, and fixing spring on the connecting seat can provide reliable clamping force after assembly, preventing the connection from loosening due to vibration during motor operation, thus improving the motor's operational stability and safety.

[0014] 4. Easy to operate: The rotating bolt at one end of the arc-shaped clamping rod engages with the threaded hole on the positioning seat. During assembly and disassembly, simply rotating the rotating bolt is enough to swing the arc-shaped clamping rod, thereby completing the connection and disassembly operations. The operation is simple and convenient. Attached Figure Description

In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the present utility model.

[0026] Reference Figure 1 , Figure 2 , Figure 3One embodiment shown is a vibration motor that is easy to assemble, comprising a motor housing 1, a motor body 2, eccentric blocks 3, end caps 4, and a quick-connect mechanism 5. In this embodiment, the motor body 2 serves as the power core of the vibration motor, and the eccentric blocks 3 are respectively installed at both ends of the motor body 2 via key connections or interference fits. When the motor body 2 is energized and rotates, the eccentric blocks 3 rotate accordingly, generating centrifugal force using their eccentric mass, thereby causing the entire motor to vibrate. This is the basis for the vibration motor to achieve its vibration function. The motor body 2 is located inside the motor housing 1, which has a split structure consisting of two half-shells 7. The two half-shells 7 are connected by the quick-connect mechanism 5. This connection method replaces the traditional bolt connection, avoiding the tedious operation of tightening bolts one by one. The motor body 2 is fixed inside the half-shells 7, which prevent external dust, moisture, and other impurities from entering and affecting the normal operation of the motor body 2. End caps 4 are respectively provided at both ends of the motor housing 1, and the end caps 4 are also connected to the half-shells 7 via the quick-connect mechanism 5. The end cap 4 further seals the inside of the motor, reducing the impact of the external environment on the internal components, and also provides some support and protection. This method of connecting the components through the quick-connect mechanism 5 greatly improves the assembly efficiency of the vibration motor, making the assembly process simpler and faster.

[0027] The implementation principle of the above embodiment is as follows: When assembling the vibration motor, the eccentric blocks 3 are first installed at both ends of the motor body 2, and then the motor body 2 is placed inside one of the half-shells 7. Then, the other half-shell 7 is connected to the first half-shell 7 via the quick-connect mechanism 5, forming a complete motor housing 1 that encloses the motor body 2. Finally, the end caps 4 are installed at both ends of the motor housing 1 using the quick-connect mechanism 5, completing the assembly of the entire motor. This design of a split housing and quick-connect mechanism 5 simplifies the assembly steps and shortens the assembly time.

[0028] Reference Figure 3 , Figure 4 , Figure 7 , Figure 8One embodiment shown is as follows: The quick-connect mechanism 5 includes a positioning seat 8, a connecting seat 9, and a quick-connect assembly 10. In this embodiment, the positioning seat 8 and the connecting seat 9 are respectively installed at one end of two connected components (such as two half-shells 7 or half-shell 7 and end cap 4). The positioning seat 8 and the connecting seat 9 are connected by a plurality of quick-connect assemblies 10. A first positioning groove 11 in the quick-connect assembly 10 is formed on the periphery of the connecting seat 9, and a first positioning protrusion 12 that can be inserted into the first positioning groove 11 is fixedly formed on the positioning seat 8. The first positioning protrusion 12 and the first positioning groove 11 have a concave-convex fit connection relationship. When assembling, the positioning seat 8 and the connecting seat 9 are brought close together, so that the first positioning protrusion 12 is aligned with the first positioning groove 11 and inserted. This fit can limit the relative movement of the positioning seat 8 and the connecting seat 9 in one direction, achieve preliminary positioning, and ensure that the two connected components are accurately positioned in that direction. At the same time, a second positioning groove 13 is also formed on the connecting seat 9, and a second positioning protrusion 14 that can be inserted into the second positioning groove 13 is fixedly formed on the positioning seat 8. The second positioning protrusion 14 and the second positioning groove 13 also have a concave-convex fit relationship. After insertion, they can restrict the relative movement of the positioning seat 8 and the connecting seat 9 in another direction, further refining the relative position of the positioning seat 8 and the connecting seat 9. Through the cooperation of the first positioning protrusion 12 and the first positioning groove 11, and the second positioning protrusion 14 and the second positioning groove 13, the precise positioning of the positioning seat 8 and the connecting seat 9 in the plane is achieved, providing an accurate foundation for subsequent fastening and connection. This ensures that the two connected parts can be accurately aligned during connection, improving the assembly accuracy and stability.

[0029] The implementation principle of the above embodiment is as follows: When connecting two components via the quick-connect mechanism 5, the positioning seat 8 and the connecting seat 9 are first brought close together, so that the first positioning protrusion 12 aligns with the first positioning groove 11 and the second positioning protrusion 14 aligns with the second positioning groove 13. Then, the positioning protrusions are inserted into the corresponding positioning grooves. The cooperation between these two positioning protrusions and positioning grooves is like two pieces of a jigsaw puzzle fitting together, restricting the relative movement of the positioning seat 8 and the connecting seat 9 in the plane, ensuring the positional accuracy of the two components during connection, thereby improving the stability and reliability of the entire connection structure.

[0030] Reference Figure 1 , Figure 4 , Figure 6One embodiment shown depicts two quick-connect components 10 evenly distributed around the periphery of the connector 9. In this embodiment, the use of two quick-connect components 10 evenly distributed around the connector 9 results in a more balanced and stable connection between the positioning base 8 and the connector 9. The two quick-connect components 10 function at different positions around the connector 9, collectively constraining the relative positions of the positioning base 8 and the connector 9. When the two connected components are connected to the connector 9 via the positioning base 8, the two quick-connect components 10 can simultaneously provide positioning and connection functions at different positions, avoiding connection instability caused by single-point connections.

[0031] The implementation principle of the above embodiment is as follows: During motor operation, the force generated by vibration will affect the connection between the positioning seat 8 and the connecting seat 9. Two evenly distributed quick-connect components 10 can distribute these forces to different locations, avoiding excessive local stress that could lead to loosening of the connection. By evenly arranging two quick-connect components 10 around the connecting seat 9, during assembly, the two components simultaneously serve as positioning and connecting components, ensuring that the positioning seat 8 and the connecting seat 9 are effectively constrained in multiple directions, thereby improving the stability and reliability of the entire connection structure.

[0032] Reference Figure 7 , Figure 8 , Figure 9One embodiment is shown: a slot 15 is provided on the connecting seat 9, and a swingable arc-shaped clamping rod 16 is hinged within the slot 15. In this embodiment, the arc-shaped clamping rod 16 is connected to the inner wall of the slot 15 via a hinge shaft. This hinged connection allows the arc-shaped clamping rod 16 to swing freely around the hinge shaft within the slot 15. A fixed protrusion 17 is provided at one end of the arc-shaped clamping rod 16, and a slidable limiting rod 18 is slidably connected within the slot 15. The positional relationship between the fixed protrusion 17 and the limiting rod 18 ensures that when the arc-shaped clamping rod 16 swings, the fixed protrusion 17 can contact the limiting rod 18 and push it to move. A fixed compression spring 19 is fixed to the limiting rod 18, with one end of the fixed compression spring 19 connected to the limiting rod 18 and the other end fixed within the slot 15. This connection method ensures that the limiting rod 18 is in a relatively stable position under the elastic force of the fixed compression spring 19 when no external force is applied. The positioning seat 8 has a limiting groove 20 communicating with the slot 15. When the arc-shaped clamping rod 16 rotates in a specific direction, the fixed protrusion 17 pushes the limiting rod 18 to overcome the elastic force of the fixed spring 19 and slide towards the limiting groove 20 on the positioning seat 8. Finally, the limiting rod 18 is inserted into the limiting groove 20. At this time, the arc-shaped clamping rod 16, through the cooperation of the fixed protrusion 17 and the limiting rod 18 with the limiting groove 20, tightly fixes the positioning seat 8 and the connecting seat 9 together, realizing a tight connection between the positioning seat 8 and the connecting seat 9. The effect of this connection method is that when the motor vibrates, the limiting rod 18 is stably held in the limiting groove 20 under the action of the fixed spring 19, preventing the limiting rod 18 from accidentally slipping out, and ensuring a stable and reliable connection between the positioning seat 8 and the connecting seat 9. At the same time, the insertion and withdrawal of the limiting rod 18 can be controlled by the swing of the arc-shaped clamping rod 16, making the operation convenient and quick.

[0033] The implementation principle of the above embodiment is as follows: When it is necessary to connect the positioning seat 8 and the connecting seat 9, the arc-shaped clamping rod 16 is rotated, causing the fixed protrusion 17 to push the limiting rod 18 to move. During the movement, the limiting rod 18 compresses the fixed spring 19. When the limiting rod 18 moves to align with the limiting groove 20, it is inserted into the limiting groove 20 under the continuous pushing of the arc-shaped clamping rod 16. After the limiting rod 18 is inserted into the limiting groove 20, the fixed spring 19 provides a reverse elastic force, so that the limiting rod 18 is stably held in the limiting groove 20. In this way, through the cooperation of the arc-shaped clamping rod 16, the limiting rod 18, the fixed spring 19, and the limiting groove 20, a reliable connection between the positioning seat 8 and the connecting seat 9 is achieved, and this connection method can also maintain stability when the motor vibrates.

[0034] Reference Figure 5 , Figure 7One embodiment is shown where a rotatable rotating bolt 21 is movably connected to the other end of the arc-shaped clamping rod 16. A threaded hole 22 is provided on the positioning seat 8, into which the rotating bolt 21 can be inserted. In this embodiment, when connecting the positioning seat 8 and the connecting seat 9, the arc-shaped clamping rod 16 is first manually pushed. The arc-shaped clamping rod 16 is connected to the inner wall of the slot 15 on the connecting seat 9 via a hinge shaft. This hinged connection gives the arc-shaped clamping rod 16 the freedom to swing around the hinge shaft, thus allowing it to be pushed smoothly. When the arc-shaped clamping rod 16 is pushed to fit against the connecting seat 9, its motion characteristics begin to function. A fixed protrusion 17 at one end of the arc-shaped clamping rod 16 contacts a sliding limiting rod 18 within the slot 15. As the arc-shaped clamping rod 16 swings, the fixed protrusion 17 applies a pushing force to the limiting rod 18. A fixing spring 19 is provided on the limiting rod 18. One end of the fixing spring 19 is connected to the limiting rod 18, and the other end is fixed in the slot 15. Under the push of the fixing protrusion 17, the limiting rod 18 overcomes the elastic force of the fixing spring 19 and begins to slide. The positioning seat 8 has a limiting groove 20 that communicates with the slot 15. During the sliding process, the limiting rod 18 gradually approaches and finally inserts into the limiting groove 20. This process initially achieves the relative fixation between the positioning seat 8 and the connecting seat 9. After the limiting rod 18 is inserted into the limiting groove 20, the rotating bolt 21 is then rotated. When the rotating bolt 21 is rotated, due to the transmission action of the thread, the rotating bolt 21 will move axially along the threaded hole 22. As the rotating bolt 21 is screwed into the threaded hole 22, the arc-shaped clamping rod 16 and the positioning seat 8 are finally fastened. This connection method achieves significant results. By manually pushing the arc-shaped clamping rod 16, the limiting rod 18 is inserted into the limiting groove 20, completing the initial positioning and pre-fixation, providing a good foundation for the subsequent tightening of the rotating bolt 21. The tightening between the arc-shaped clamping rod 16 and the positioning seat 8 achieved by rotating the bolt 21 further enhances the stability and reliability of the connection between the positioning seat 8 and the connecting seat 9. Under conditions of motor vibration, this double-connection structure effectively prevents loosening, ensuring a stable connection between motor components and extending the motor's service life. Furthermore, when disassembly is required, simply rotating the rotating bolt 21 in the reverse direction causes the arc-shaped clamping rod 16 to swing in the opposite direction, and the limiting rod 18 slides out of the limiting groove 20 under the action of the fixed compression spring 19, easily disengaging the connection and improving the efficiency of motor assembly and maintenance.

[0035] The implementation principle of the above embodiment is as follows: Utilizing the swing characteristics of the arc-shaped clamping rod 16 and the thread transmission principle of the rotating bolt 21, the arc-shaped clamping rod 16 is first manually operated to drive the limiting rod 18 into the limiting groove 20, achieving initial positioning and pre-fixation. Then, by screwing in the rotating bolt 21, the arc-shaped clamping rod 16 and the positioning seat 8 are further tightened, completing the entire connection process. Disassembly is performed in reverse; by rotating the bolt 21 in the opposite direction, the arc-shaped clamping rod 16 swings, and the limiting rod 18 slides out of the limiting groove 20, releasing the connection. This operation method combines the flexibility of manual operation with the stability of threaded transmission, making the connection and disassembly process between the positioning seat 8 and the connecting seat 9 both convenient and reliable.

[0036] The working principle of this device is as follows: When assembling the vibratory motor, the eccentric blocks 3 are first installed at both ends of the motor body 2, and their stability is ensured by key connection or interference fit. Then, the motor body 2 with the eccentric blocks 3 is placed inside one of the half-shells 7. Next, the other half-shell 7 is aligned with the first half-shell 7. At this time, the first positioning protrusion 12 on the positioning seat 8 aligns with the first positioning groove 11, and the second positioning protrusion 14 and the second positioning groove 13 on the connecting seat 9, respectively, and are inserted to achieve preliminary precise positioning, restricting the relative movement of the positioning seat 8 and the connecting seat 9 in the plane. After the preliminary positioning is completed, the fastening connection operation is performed. First, the arc-shaped clamping rod 16 hinged in the groove 15 of the connecting seat 9 is manually pushed to fit against the connecting seat 9. Since the fixed protrusion 17 at one end of the arc-shaped clamping rod 16 is in contact with the sliding limiting rod 18 in the slot 15, as the arc-shaped clamping rod 16 swings, the fixed protrusion 17 pushes the limiting rod 18 to overcome the elastic force of the fixed compression spring 19 and slide towards the limiting groove 20 on the positioning seat 8 until the limiting rod 18 is inserted into the limiting groove 20, thus completing the initial fixation.

[0037] Next, rotate the rotating bolt 21 at the other end of the arc-shaped clamping rod 16. The rotating bolt 21 is fixedly connected to the arc-shaped clamping rod 16 and threadedly engaged with the threaded hole 22 on the positioning seat 8. As the rotating bolt 21 is screwed into the threaded hole 22, the axial movement of the rotating bolt 21 drives the arc-shaped clamping rod 16 to move further towards the positioning seat 8, thereby achieving a tight connection between the arc-shaped clamping rod 16 and the positioning seat 8. This ensures a firm connection between the positioning seat 8 and the connecting seat 9, thus completing the connection between the two half-shells 7 or between the half-shell 7 and the end cover 4.

[0038] When the motor needs to be disassembled, the rotating bolt 21 is rotated in the reverse direction. Rotating the bolt 21 causes the arc-shaped clamping rod 16 to swing in the opposite direction. Under the action of the fixed spring 19, the limiting rod 18 slides out of the limiting groove 20, releasing the connection between the positioning seat 8 and the connecting seat 9. This allows for easy separation of the components, facilitating motor maintenance or component replacement. During motor operation, the quick-connect mechanism 5 provides dual fixing: the cooperation between the limiting rod 18 and the limiting groove 20, and the tightness between the arc-shaped clamping rod 16 and the positioning seat 8. This effectively resists the forces generated by motor vibration, prevents loosening of the connection, and ensures stable motor operation.

[0039] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
