Description
Technical Field
[0001] This utility model relates to the field of vibratory wheel technology, and in particular to a thin oil lubricated vibrator. Background Technology
[0002] A thin oil-lubricated vibrator is a vibration device that uses a thin oil film to reduce friction and wear. It achieves relative motion between the vibrating components by forming an oil film between them. When the vibrator's motor drives the eccentric block to rotate, an outward centrifugal force is generated because the eccentric block's center of mass is not on the rotation axis. The magnitude and direction of this force change as the eccentric block rotates.
[0003] Some existing technologies use a fixed eccentric block design, which means that the magnitude and direction of the excitation force are fixed. When the vibrator is adjusting the eccentric block, it is often necessary to disassemble the eccentric block and then reinstall it in the appropriate position as needed. This process is not only time-consuming and labor-intensive, but also increases the difficulty and cost of equipment maintenance.
[0004] Therefore, this utility model provides a thin oil lubricated vibrator. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a thin oil lubricated vibrator.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a thin oil lubricated vibrator, characterized in that it comprises;
[0007] Vibration shaft;
[0008] Adjustment assembly; the adjustment assembly includes an active eccentric block fixedly connected to the vibration shaft, an adjustment groove is provided inside the active eccentric block, a rotating shaft is rotatably connected to the bottom end of the adjustment groove, and an auxiliary adjustment eccentric block is fixedly connected to the outside of the rotating shaft;
[0009] A fixing component, one end of which is fixedly connected to a pressure component; the fixing component includes an adjusting block fixedly connected to an auxiliary adjusting eccentric block, a limiting washer is sleeved on the outer side of the adjusting block, a threaded groove is opened on the outer side of the adjusting block, and a connecting post is threadedly connected to the threaded groove.
[0010] The technical advantages of adopting the above solution are: users can change the position of the auxiliary adjusting eccentric block by adjusting the connecting column according to different working requirements, thereby changing the magnitude and direction of the excitation force. Due to the structural design of the adjusting component, the adjustment process does not require disassembling the eccentric block, greatly simplifying the operation process and reducing maintenance difficulty and cost.
[0011] In a preferred embodiment, the pressure assembly includes a threaded post fixedly connected to a connecting post, a rotating block threadedly connected to the outer side of the threaded post, a hollow rotating post rotatably connected to the end of the rotating block near the limiting washer, and a pressure spring sleeved on the outer side of the threaded post.

[0013] In a preferred embodiment, the outer side of the adjusting block is slidably connected to the inside of the active eccentric block.
[0014] The technical effect of adopting the above technical solution is that the sliding connection between the adjusting block and the active eccentric block allows the user to adjust the eccentricity of the exciter more flexibly.
[0015] In a preferred embodiment, the outer side of the auxiliary adjustment eccentric block is slidably connected to the adjustment groove via a rotating shaft.
[0016] The technical effect of adopting the above technical solution is that it enables users to flexibly adjust the eccentricity of the vibrator according to actual working conditions.
[0017] The outer side of the auxiliary adjustment eccentric block is slidably connected to the adjustment groove via a rotating shaft, allowing the eccentric block to be freely adjusted in angle within the adjustment groove.
[0018] In a preferred embodiment, one end of the limiting washer is in contact with the connecting post, and the other end of the limiting washer is in contact with the outer side of the active eccentric block.
[0019] The technical effect of adopting the above technical solution is that the setting of the limiting washer ensures that the relative position between the active eccentric block and the vibration shaft remains stable when the vibrator is working, preventing excessive displacement caused by vibration.
[0020] In a preferred embodiment, one end of the pressure spring is rotatably connected to a threaded column, and the other end of the pressure spring is rotatably connected to a hollow rotating column.
[0021] The technical effect of adopting the above technical solution is that the two ends of the pressure spring are fixedly connected to the threaded column and the hollow rotating column respectively, which ensures that the screws are reduced from loosening during the operation of the vibrator.
[0022] In a preferred embodiment, the outer side of the active eccentric block is fixedly connected with scale lines.
[0023] The technical effect of adopting the above technical solution is that, by setting the scale lines, the operator can intuitively observe the adjustment position of the eccentric block, thereby accurately controlling the vibration amplitude of the exciter.
[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0025] In adjusting the centrifugal force, this invention first rotates the rotating block to release the pressure of the vibration shaft pressure assembly on the connecting column. Then, the connecting column is rotated to release the contact between the limiting washer and the active eccentric block. The operator can hold the connecting column and slide it towards the active eccentric block, assisting the eccentric block to slide on the adjustment groove. The required centrifugal force is selected according to the scale lines on the active eccentric block. After adjustment, the connecting column is rotated to make the limiting washer and the active eccentric block tightly connected. Finally, the adjustment groove is rotated to compress the pressure spring on the threaded column, enhancing the connection between the connecting column and the threaded groove. This design allows for adjustment of the magnitude and direction of the excitation force without disassembling any components, greatly simplifying the adjustment process, improving the convenience and efficiency of operation, and reducing the maintenance difficulty and cost of the equipment. Furthermore, the pressure spring can stably provide continuous pressure to the connecting column, ensuring a stable connection between the connecting column and the threaded groove.

[0035] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a thin oil lubricated vibrator, comprising;
[0037] Vibration shaft 1;
[0038] Adjustment component 2; Adjustment component 2 includes an active eccentric block 21 fixedly connected to the vibration shaft 1. An adjustment groove 22 is provided inside the active eccentric block 21. A rotating shaft 23 is rotatably connected to the bottom end of the adjustment groove 22. An auxiliary adjustment eccentric block 24 is fixedly connected to the outside of the rotating shaft 23. The outside of the auxiliary adjustment eccentric block 24 is slidably connected to the adjustment groove 22 through the rotating shaft 23. A scale line 25 is fixedly connected to the outside of the active eccentric block 21.
[0039] The vibration shaft 1 is the core component of the vibrator. It generates excitation force through rotation, causing the equipment to vibrate. The active eccentric block 21 achieves excitation through the centrifugal force generated by its eccentric mass. The adjustment groove 22 is used to accommodate the rotating shaft 23 and the auxiliary adjustment eccentric block 24, allowing the rotating shaft 23 and the auxiliary adjustment eccentric block 24 to rotate flexibly, facilitating the adjustment of the magnitude and direction of the excitation force. The rotating shaft 23 is connected to the auxiliary adjustment eccentric block 24, and the auxiliary adjustment eccentric block 24 slides in the adjustment groove 22 to achieve fine adjustment of the excitation force. The auxiliary adjustment eccentric block 24 is connected to the rotating shaft 23, and the excitation force is finely adjusted by changing its position. The scale line 25 provides an intuitive reference, allowing the operator to accurately adjust the position of the eccentric block and ensure that the working state of the vibrator meets expectations.
[0040] like Figure 1 - Figure 4 As shown, the fixing component 3 includes an adjusting block 31 fixedly connected to the auxiliary adjusting eccentric block 24. The outer side of the adjusting block 31 is slidably connected to the inside of the active eccentric block 21. A limiting washer 32 is sleeved on the outer side of the adjusting block 31. The other end of the limiting washer 32 contacts the outer side of the active eccentric block 21. A threaded groove 33 is opened on the outer side of the adjusting block 31. A connecting post 34 is threadedly connected to the threaded groove 33. One end of the limiting washer 32 contacts the connecting post 34.
[0041] The adjusting block 31 is fixedly connected to the auxiliary adjusting eccentric block 24, and its outer side is slidably connected to the inside of the active eccentric block 21. It is used to adjust the working state of the vibrator. The limiting washer 32 is used to limit the movement range of the adjusting block 31 to prevent it from moving excessively and to ensure that the adjusting block 31 will not exceed the predetermined position during the adjustment process. The threaded groove 33 is used to thread the connecting column 34, providing a way to adjust and fix the position of the adjusting block 31. The connecting column 34 provides a reliable fixing method through threaded connection, ensuring that the adjusting block 31 can be stably maintained after being adjusted to the appropriate position, and avoiding displacement due to vibration or impact.
[0042] like Figure 1 , Figure 3 and Figure 4 As shown, a pressure component 4 is fixedly connected to one end of the fixing component 3. The pressure component 4 includes a threaded post 41 fixedly connected to the connecting post 34. A rotating block 42 is threadedly connected to the outer side of the threaded post 41. A hollow rotating post 43 is rotatably connected to one end of the rotating block 42 near the limiting washer 32. A pressure spring 44 is sleeved on the outer side of the threaded post 41. One end of the pressure spring 44 is rotatably connected to the threaded post 41, and the other end of the pressure spring 44 is rotatably connected to the hollow rotating post 43.
[0043] The threaded post 41 provides a linear adjustment point. The rotation of the rotating block 42 achieves linear movement by rotating with the threaded post 41. The design of the hollow rotating post 43 prevents the rotating block 42 from deforming the spring during rotation. Subsequently, one end of the pressure spring 44 is rotatably connected to the threaded post 41, and the other end is rotatably connected to the hollow rotating post 43 to provide stable pressure on the connecting post 34 and increase the stability of the connection.
[0044] Working principle: such as Figure 1 - Figure 4As shown: During use: In the process of adjusting the centrifugal force, firstly, the pressure applied to the connecting column 34 by the vibration shaft 1 pressure assembly 4 needs to be released by rotating the rotating block 42. Then, continue to rotate the connecting column 34 to release the contact between the limiting washer 32 and the active eccentric block 21. At this time, the operator can hold the connecting column 34 and slide it to one side of the active eccentric block 21 to assist in adjusting the eccentric block 24 so that it can slide on the adjustment groove 22 via the rotating shaft 23. During the adjustment process, the operator can select the desired centrifugal force according to the scale line 25 on the active eccentric block 21. After adjusting the centrifugal force, the connecting column 34 needs to be rotated so that it moves closer to the active eccentric block 21 along the threaded groove 33. In this way, the limiting washer 32 can be tightly connected to the active eccentric block 21. Finally, by rotating the adjusting groove 22 and rotating it on the threaded column 41, it moves towards the active eccentric block 21, causing the pressure spring 44 connected to the threaded column 41 to be compressed. This series of actions will ultimately increase the connection force between the connecting column 34 and the threaded groove 33, ensuring the stability and accuracy of the entire system.
[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
