Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a multi-angle adjustable structure for the grinding wheel head of a grinding machine. Background Technology

[0002] In the field of machining, grinding machines, as precision machining equipment, directly affect the workpiece machining quality through the accuracy of the grinding wheel head angle adjustment. For complex curved surfaces and multi-station machining scenarios, the grinding wheel needs to achieve multiple precise angle switching settings to adapt to the grinding requirements of different workpieces.

[0003] Traditional grinding machine wheel heads mostly employ manual angle adjustment, relying on operator experience for positioning. This is not only inefficient but also results in insufficient torque output, making them prone to angle deviation under heavy loads and failing to meet the consistency requirements of batch precision machining. Some electrically adjustable grinding wheel heads use ordinary gear transmission structures, which suffer from insufficient torque transmission. They are prone to jamming and adjustment lag when switching between high-load grinding wheel angles, and their multi-position positioning accuracy is poor, making it difficult to achieve stable locking of fine-tuned angles. A few use hydraulic or pneumatic angle adjustment structures, which can improve driving force, but they suffer from drawbacks such as complex structure, high maintenance costs, and slow response speed. They also cannot flexibly adapt to the needs of rapid switching between multiple angles, making them unsuitable for integrated applications in small and medium-sized precision grinding machines. Utility Model Content

[0004] The technical problem to be solved by this utility model is the lack of torque in the adjustment process of the existing technology. To address this, we propose a multi-angle adjustment structure for the grinding wheel head of a grinding machine.

[0005] To achieve the above objectives, this application adopts the following technical solution: a multi-angle adjustment structure for the grinding wheel head of a grinding machine, including a mounting frame, a grinding wheel mounted at the bottom of the mounting frame, a control component provided on the back of the mounting frame, the control component including an assembly cylinder, a drive roller built into the assembly cylinder, a drive gear fixedly connected to the output end of the drive roller, multiple connecting gears arranged around the drive gear, a rotating ring sleeved on the outer ring wall of the annular structure formed by the multiple connecting gears, multiple evenly distributed tooth grooves opened on the inner ring wall of the rotating ring, the rotating ring meshing with the connecting gears through the tooth grooves, the connecting gears meshing with the drive gear, and a connecting ring sleeved on the outer ring wall of the rotating ring.

[0006] Preferably, a drive component is mounted on one side of the mounting bracket.

[0007] Preferably, a rotating roller is rotatably sleeved in the middle of the connecting gear, and a fixed cylinder is rotatably connected to the end of the rotating roller away from the connecting gear.

[0008] Preferably, the diameter ratio of the drive gear to the rotating ring is 1:5.

[0009] Preferably, the outer ring wall of the rotating ring has a sliding ring surface, the sliding ring surface has a built-in sliding seat, and a positioning plate is fixedly connected to the side of the sliding seat away from the rotating ring.

[0010] Preferably, the connecting ring has multiple threaded holes on the side near the mounting bracket, and the connecting ring is fixed to the mounting bracket by bolts.

[0011] Preferably, the outer ring wall of the rotating ring is fixedly connected with a plurality of embedded seats, and the inner ring wall of the connecting ring is provided with a plurality of embedded grooves, and the embedded seats are inserted into the embedded grooves.

[0012] Preferably, the plurality of connecting gears are evenly distributed around the axis of the driving gear.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This utility model discloses a multi-angle adjustment structure for a grinding wheel head on a grinding machine. It employs a combination of independent drive and planetary gear transmission to achieve precise, stable, and efficient angle adjustment. The device includes a mounting frame (with the grinding wheel mounted at the bottom), a drive unit on one side, and a control assembly at the back. The control assembly includes an assembly cylinder and a built-in drive roller. The drive sources for the grinding wheel rotation and angle adjustment are independent of each other. The driving gear is driven by the drive roller and meshes with multiple connecting gears around its circumference. The connecting gears are rotatably connected to the fixed cylinder via a rotating roller and simultaneously mesh with a rotating ring with toothed grooves on the inner side. The diameter ratio between the driving gear and the rotating ring is 1:5. The rotating ring is precisely inserted into the connecting ring's groove via an outer ring wall embedding seat. The connecting ring is fixed to the mounting frame by bolts, and its outer ring sliding surface cooperates with the sliding seat to provide guiding support.

[0015] The angle adjustment is powered by a dedicated drive source. Power is transmitted to the drive gear via the drive roller, which in turn drives the connecting gear to perform planetary motion, rotating on its own axis and revolving around the sun. This motion, in turn, drives the rotating ring to rotate as a whole through the meshing of the gear teeth. The power is then smoothly transmitted to the mounting frame via the connecting ring, thus achieving the adjustment of the grinding wheel angle. The planetary gear transmission disperses power, increases torque, avoids stress concentration, and enhances stability and load-bearing capacity under heavy load conditions, solving the problem of insufficient torque in traditional adjustment methods. The structure is simple and compact, requiring no complex auxiliary equipment. The electric drive stepless adjustment combined with the planetary gear precision transmission allows for multi-level switching and fine-tuning of the angle, adapting to precision machining needs.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: a multi-angle adjustment structure for the grinding wheel head of a grinding machine, including a mounting frame 1, a grinding wheel 2 mounted at the bottom of the mounting frame 1, a drive component 101 mounted on one side of the mounting frame 1, and a control component 3 provided on the back of the mounting frame 1. The control component 3 includes an assembly cylinder 301, and a drive roller 302 is built into the assembly cylinder 301. The drive component 101 that drives the grinding wheel 2 to rotate and the drive roller 302 that adjusts the angle are provided with independent drive sources. When the angle is adjusted, the dedicated drive source of the drive roller 302 is activated, and the power is transmitted to the drive roller 302 inside the assembly cylinder 301. The drive roller 302 then drives the subsequent fixed drive gear 303 to rotate.

[0025] Multiple connecting gears 304 are arranged around the driving gear 303. A rotating roller 305 is rotatably sleeved in the middle of the connecting gear 304. A fixed cylinder 306 is rotatably connected to the end of the rotating roller 305 away from the connecting gear 304. A rotating ring 307 is sleeved on the outer ring wall of the annular structure formed by the multiple connecting gears 304. Multiple evenly distributed tooth grooves 308 are formed on the inner ring wall of the rotating ring 307. The rotating ring 307 is meshed with the connecting gears 304 through the tooth grooves 308. The connecting gears 304 are meshed with the driving gear 303. The diameter ratio of the driving gear 303 to the rotating ring 307 is one. Fifthly, the outer ring wall of the rotating ring 307 has a sliding ring surface 309, and a sliding seat 311 is built into the sliding ring surface 309. A positioning plate 310 is fixedly connected to the side of the sliding seat 311 away from the rotating ring 307. A connecting ring 312 is sleeved on the outer ring wall of the rotating ring 307. The side of the connecting ring 312 near the mounting bracket 1 has multiple threaded holes 315. The connecting ring 312 is fixed to the mounting bracket 1 by bolts. Multiple insert seats 313 are fixedly connected to the outer ring wall of the rotating ring 307. Multiple insert grooves 314 are opened on the inner ring wall of the connecting ring 312, and the insert seats 313 are inserted into the insert grooves 314. The driving gear 303 meshes with multiple connecting gears 304 surrounding it. The connecting gears 304 are rotatably connected to the fixed cylinder 306 through the central rotating roller 305. The fixed cylinder 306 provides a stable support base for the connecting gears 304, so that the connecting gears 304 simultaneously perform planetary motion of rotation and revolution under the drive of the driving gear 303. Since the connecting gear 304 also meshes with the toothed groove 308 on the inner ring wall of the rotating ring 307, this meshing relationship transforms the planetary motion of the connecting gear 304 into the overall rotation of the rotating ring 307. The rotating ring 307 is precisely inserted into the groove 314 of the connecting ring 312 via the insert seat 313 on the outer ring wall, ensuring synchronous transmission between the two. The connecting ring 312 is firmly connected to the mounting bracket 1 by bolts, ultimately transmitting the rotational power smoothly to the mounting bracket 1, driving the grinding wheel 2 at the bottom to achieve angle adjustment. During the rotation of the rotating ring 307, the sliding ring surface 309 on its outer ring wall closely cooperates with the sliding seat 311, providing continuous guidance and support for the rotating ring 307, effectively reducing radial offset during rotation, and ensuring a smooth and wobbly angle adjustment process.

[0026] Employing a planetary gear transmission design, the driving gear 303, connecting gear 304, and rotating ring 307 form a complete planetary gear set. This transmission method efficiently enhances torque output. The driving force is distributed through the driving gear 303 to multiple connecting gears 304, and then synchronously acts on the rotating ring 307, resulting in more uniform and efficient power transmission, avoiding stress concentration issues common in single-gear transmissions. Even under heavy-load conditions, this enhanced torque output effectively resists external interference, preventing angular misalignment of the grinding wheel holders. This significantly improves the stability and load-bearing capacity of the adjustment structure, fully meeting the stringent requirements for angular consistency in batch precision machining, and solving the core defects of insufficient torque in traditional manual adjustment and ordinary electric gear transmissions.

[0027] The solution features a simpler and more compact structure, eliminating the need for complex hydraulic lines, cylinders, air tanks, and other auxiliary equipment. The combination of electric drive stepless adjustment and planetary gear transmission provides highly flexible angle adjustment, enabling rapid adaptation to the switching needs of multiple angle settings. The precision transmission characteristics of the planetary gear set allow for accurate angle control, and combined with the electric drive stepless adjustment function, continuous fine-tuning of the angle can be achieved to meet the precise angle requirements of precision machining.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
