Description

Technical Field

[0001] This utility model relates to the technical field of eccentric disk mechanisms, and in particular to an eccentric disk mechanism with adjustable eccentricity. Background Technology

[0002] An eccentric disk is a common mechanical component used in many mechanical devices. It is typically a circular, disc-shaped object whose center and axis of rotation are eccentric. That is, the axis of rotation does not pass through the geometric center of the disk. This eccentric design is its key feature. For example, in some simple eccentric disk models, the distance between the center hole (for mounting on a shaft) and the edge of the disk is unequal, thus creating the eccentric structure.

[0003] The eccentricity of the eccentric disk determines its maximum displacement (i.e., stroke) during rotation. In many mechanical systems, the equipment needs to adjust the stroke according to different working conditions or processing requirements. The eccentric position of the eccentric output shaft on the existing drive disk is fixed and cannot be adjusted. When different degrees of eccentric movement are required for processing, the fixed eccentric disk cannot meet the processing requirements and has poor adaptability. Therefore, an eccentric disk mechanism with adjustable eccentricity is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an eccentric disk mechanism with adjustable eccentricity to solve the aforementioned problems.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the eccentric disk mechanism with adjustable eccentricity has multiple eccentric mounting posts at the bottom of the eccentric disk body. The multiple eccentric mounting posts are located at different diameter positions on the eccentric disk body. By selecting a suitable eccentric mounting post and connecting it to the eccentric shaft, the eccentricity can be adjusted. The set plug-in positioning component can realize a stable connection between the shaft end block and the eccentric mounting post.

Detailed Implementation

[0021] 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.

[0022] Example: Refer to Figure 1-5 An adjustable eccentric disk mechanism includes an eccentric disk body 1, a rotary drive assembly located below the eccentric disk body 1, a shaft end block 4 connected to the rotary drive assembly, and multiple eccentric mounting posts 5 fixedly mounted on the bottom of the eccentric disk body 1. During use, the eccentricity of the eccentric disk body 1 is adjusted according to different usage requirements. The multiple eccentric mounting posts 5 are located at different diameter positions on the eccentric disk body 1 and are staggered or horizontally positioned, fixedly installed according to actual processing needs. The position of 5 is set according to the position required by frequent use, without the need for fine adjustment of the eccentricity. An insertion positioning component is provided between the eccentric mounting column 5 and the shaft end block 4. An anti-detachment positioning component is provided on the eccentric mounting column 5, which is adapted to the shaft end block 4. An external clamping component is provided on the eccentric mounting column 5, which is adapted to the anti-detachment positioning component. The rotation drive component includes a drive motor 2 located below the eccentric disk body 1. The output end of the drive motor 2 is connected to the eccentric shaft 3. The top end of the eccentric shaft 3 is fixedly connected to the side of the shaft end block 4. The rotation drive component facilitates the rotation of the eccentric shaft 3.

[0023] Furthermore, the insertion positioning assembly includes a mounting positioning groove 6 formed at the end of the eccentric mounting column 5, and a mounting positioning block 7 fixedly installed on the side of the shaft end block 4. The mounting positioning block 7 is engaged within the mounting positioning groove 6. Both the mounting positioning groove 6 and the mounting positioning block 7 are cross-shaped. After selecting a suitable eccentricity position, the mounting positioning block 7 is inserted into the mounting positioning groove 6. The mounting positioning block 7 is cross-shaped, and after installation, it can achieve a stable rotational driving effect. The anti-detachment positioning assembly includes a mounting positioning groove 6 formed on the side of the eccentric mounting column 5. The mounting groove 8 of the part is fixedly installed with a rotating shaft 9. A rotating pressure rod 10 is rotatably sleeved on the rotating shaft 9. An anti-detachment positioning block 11 is fixedly installed on one side of the rotating pressure rod 10. A positioning slot 12 is opened on the side of the shaft end block 4. The anti-detachment positioning block 11 is locked in the positioning slot 12. After being inserted into the position, the anti-detachment positioning block 11 is rotated and rotated into the positioning slot 12. The width of the positioning slot 12 is slightly larger than that of the anti-detachment positioning block 11 to facilitate the rotation and locking of the anti-detachment positioning block 11.

[0024] Furthermore, the external clamping assembly includes a threaded groove 13 on the eccentric mounting post 5, with a nut 14 threaded onto the threaded groove 13. The outer side of the rotating pressure rod 10 has an arc-shaped structure, and the rotating pressure rod 10 is adapted to the nut 14. A tail stop 15 and an end stop 16 are fixedly installed on the outer side of the eccentric mounting post 5. The tail stop 15 and the end stop 16 are located on both sides of the nut 14. After snapping, the shaft end block 4 will be stably connected to the eccentric mounting post 5 without detachment. Then, the nut 14 is rotated downwards and rotated to the outside of the rotating pressure rod 10, where the rotating pressure rod 10 will be blocked. At this time, the anti-detachment positioning block 11 will not detach from the positioning slot 12, and a stable connection will be formed. The tail stop 15 and the end stop 16 can block the position of the nut 14.

[0025] In use: When the eccentricity of the eccentric disc body 1 needs to be adjusted, select a suitable eccentricity position and insert the mounting positioning block 7 into the mounting positioning groove 6. This will enable stable rotation. After insertion, rotate the anti-detachment positioning block 11 until it rotates into the positioning groove 12. The shaft end block 4 will then be stably connected to the eccentric mounting column 5, preventing detachment. Rotate the nut 14 until it rotates to the outside of the rotating pressure rod 10. The rotating pressure rod 10 will then be blocked, and the anti-detachment positioning block 11 will not detach from the positioning groove 12. This makes it convenient to use.
