Description

Technical Field

[0001] This utility model relates to the field of machining and grinding equipment technology, specifically to a grinding tool angle adjustment and vibration reduction device. Background Technology

[0002] In the field of machining, tool sharpening is a crucial step in ensuring machining accuracy and efficiency. Grinding wheel sharpening devices are commonly used sharpening equipment, and their core requirement is to precisely maintain the relative angle between the grinding wheel and the cutting tool, ensuring stability during high-speed grinding and preventing vibration. Existing sharpening devices generally have several shortcomings: First, the angle adjustment mechanism is often complex, requiring replacement of the entire component or tedious disassembly and adjustment, making it difficult to quickly adapt to different sharpening angle requirements and resulting in poor flexibility. Second, the grinding wheel generates lateral forces and vibrations during high-speed grinding. Traditional mounting structures lack sufficient rigidity or effective vibration damping measures, easily leading to slight wobble or vibration in the grinding wheel mounting seat. This vibration not only reduces the quality of the ground surface, causing serrations or burns on the cutting edge and affecting tool life, but also causes uncontrollable deviations in the preset sharpening angle during machining, seriously affecting the safety and reliability of sharpening.

[0003] Therefore, there is an urgent need for a device that can conveniently and quickly adjust the angle, and effectively suppress vibration and maintain the stability of the grinding wheel posture during operation. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Furthermore, the mounting plate and the fixing plate are connected by an adjustable structure; the adjustable structure includes two spaced-apart locking holes on the fixing plate and a round hole and an elliptical hole on the mounting plate that correspond to and cooperate with the two locking holes respectively; a bolt passes through the round hole and the corresponding locking hole in sequence to enable the mounting plate to rotate around the axis of the bolt; another bolt passes through the elliptical hole and the other locking hole in sequence to lock and fix the mounting plate with the adjusted angle.

[0008] Furthermore, the linkage assembly includes an upper linkage and a lower linkage arranged in parallel, as well as a left cantilever and a right cantilever arranged in parallel; the middle part of the upper linkage and the lower linkage is movably connected to the mounting plate through a first rotating shaft structure and a second rotating shaft structure; the upper part of the left cantilever and the right cantilever is movably connected to the two ends of the upper linkage and the lower linkage through a bearing structure to form a parallel four-bar linkage mechanism.

[0014] 1. The design of the combination of round and elliptical holes enables stepless adjustment of the angle between the mounting plate and the fixed plate.

[0024] 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.

[0025] See Figure 1-6As shown, this embodiment provides a grinding angle adjustment and vibration damping device, including a fixing plate 1 for fixing the entire device to an external base. An adjustable mounting plate 2 is provided on one side of the fixing plate 1. A connecting rod assembly 3 is movably connected to one side of the mounting plate 2, and a drive mechanism 4 (a motor) is provided on the other side to drive the connecting rod assembly 3 to swing. A grinding wheel mounting seat 5 is connected to the end of the connecting rod assembly 3 away from the mounting plate 2, and the grinding wheel mounting seat 5 is used to mount the grinding wheel assembly. A vibration damping mechanism 6 is provided on the connecting rod assembly 3, and the telescopic end of the vibration damping mechanism 6 acts on the grinding wheel mounting seat 5 to suppress vibration. With this grinding angle adjustment and vibration damping device, the operator can change the initial angle of the grinding wheel assembly as a whole according to the grinding requirements of different tools, without needing to replace the entire device or perform complex disassembly and assembly. The telescopic end of the vibration damping mechanism 6 acts directly on the grinding wheel mounting seat 5, actively counteracting the sway caused by lateral forces or vibrations during operation, forcing the grinding wheel mounting seat 5 to remain stable. This minimizes large angle sway of the grinding wheel during grinding, improving the stability and safety of the grinding.

[0026] See Figures 3 to 4 As shown, the mounting plate 2 and the fixed plate 1 are connected by an adjustable structure. The adjustable structure includes two spaced-apart locking holes 11 on the fixed plate 1, and a round hole 21 and an elliptical hole 22 on the mounting plate 2 that correspond to and engage with the two locking holes 11. A bolt passes through the round hole 21 and the corresponding locking hole 11 in sequence to allow the mounting plate 2 to rotate around the bolt's axis. Another bolt passes through the elliptical hole 22 and the other locking hole 11 in sequence to lock and fix the adjusted mounting plate 2. Loosening the bolt on the elliptical hole 22 allows the mounting plate 2 to rotate around the axis of the bolt in the round hole. The angle adjustment is very simple and requires no special tools. After adjusting to the desired angle, simply tighten the bolt on the elliptical hole 22; the friction between the bolt head and the plate surface will achieve a secure lock. To further improve the connection stability between the mounting plate 2 and the fixing plate 1, an adjustable connection position is added between the mounting plate 2 and the fixing plate 1. The upper adjustable structure of this connection position is basically the same as the one mentioned above, except that two spaced-apart lock holes 11 are provided on the mounting plate 2, and round holes 21 and elliptical holes 22 that correspond to the two lock holes 11 are provided on the fixing plate 1.

[0027] See Figure 3 , Figure 5As shown, the linkage assembly 3 includes an upper linkage 31 and a lower linkage 32 arranged in parallel, and a left cantilever 33 and a right cantilever 34 arranged in parallel. The middle parts of the upper linkage 31 and the lower linkage 32 are movably connected to the mounting plate 2 through a rotating shaft structure 1 7 and a rotating shaft structure 2 8. The upper parts of the left cantilever 33 and the right cantilever 34 are movably connected to the two ends of the upper linkage 31 and the lower linkage 32 through a bearing structure 9 to form a parallel four-bar linkage mechanism. The grinding wheel mounting base 5 is movably connected to the lower part of the left cantilever 33 and the right cantilever 34. The symmetrical double cantilever design makes the load and force evenly distributed, making the grinding wheel run more smoothly and further enhancing the rigidity and stability of the entire system during operation.

[0028] The lower part of the left cantilever 33 and the right cantilever 34 is provided with a mounting groove 35. The grinding wheel mounting seat 5 is disposed in the mounting groove 35 and connected to the left cantilever 33 and the right cantilever 34. The end of the grinding wheel mounting seat 5 away from the cantilever is provided with a connecting part 51 for connecting the grinding wheel. By providing the mounting groove 35 in the lower part of the left cantilever 33 and the right cantilever 34, an enclosed and stable mounting space is provided for the grinding wheel mounting seat 5, which improves the support rigidity and stability of the grinding wheel mounting seat 5.

[0029] The drive mechanism 4 is connected to the rotating shaft structure 7. A drive block 71 is fixedly installed at the end of the rotating shaft structure 7, and a drive groove 311 adapted to the drive block 71 is provided in the middle of the upper connecting rod 31. The drive mechanism 4 drives the rotating shaft structure 7 to rotate, and drives the upper connecting rod 31 to move through the cooperation of the drive block 71 and the drive groove 311. The fitting design of the drive block 71 and the drive groove 311 ensures that the rotational motion input by the drive mechanism 4 is accurately converted into the swing of the connecting rod, thereby improving the control accuracy and response speed of the entire device.

[0030] See Figure 3 , Figure 6 As shown, the vibration damping mechanism 6 is symmetrically arranged on opposite sides of the left cantilever 33 and the right cantilever 34. The vibration damping mechanism 6 includes a telescopic cylinder 61 and a cylinder mounting seat 62. The cylinder mounting seat 62 is fixedly installed on the side of the cantilever, and the telescopic cylinder 61 is mounted on the cylinder mounting seat 62. Its telescopic end 611 passes through the cylinder mounting seat 62 and abuts against the side wall of the grinding wheel mounting seat 5. The two symmetrically arranged telescopic cylinders 61 can simultaneously apply a balanced locking force from both sides, actively constraining the horizontal degree of freedom of the grinding wheel mounting seat 5, suppressing sway, and maintaining stability. By controlling the air pressure of the telescopic cylinder 61, the locking force on the grinding wheel mounting seat 5 can be flexibly adjusted to adapt to different power and different grinding conditions. The cylinder mounting seat 5 is fixed on the cantilever and moves with the linkage mechanism without interfering with other parts of the device. At the same time, the telescopic end 611 of the telescopic cylinder 61 can always effectively act on the grinding wheel mounting seat 5.

[0031] A spring is installed between the cylinder mounting base 62 and the grinding wheel mounting base 5, with both ends of the spring abutting against the side walls of the cylinder mounting base 62 and the grinding wheel mounting base 5, respectively. The spring and the telescopic cylinder are connected in parallel, forming a double safety mechanism of "pneumatic rigid locking + elastic flexible buffering." The spring can continuously absorb high-frequency micro-vibrations, while the telescopic cylinder provides active suppression of sway. Furthermore, in the event of an unexpected loss of pressure in the telescopic cylinder due to a failure in the air supply, the spring can still provide a certain degree of buffering and limiting effect, preventing the grinding wheel mounting base 5 from suddenly shaking violently, thus improving the safety and reliability of the device.

[0032] The working principle of this utility model is as follows:

[0033] When the grinding angle needs to be adjusted, the operator simply needs to loosen the bolt passing through the elliptical hole 22. At this time, the mounting plate 2 can rotate freely around the bolt axis passing through the circular hole 21. After rotating the mounting plate 2 and the connected linkage mechanism and grinding wheel assembly to the desired angle, the bolt on the elliptical hole 22 is tightened again to complete the fine adjustment of the angle.

[0034] During the grinding process, the telescopic end 611 of the telescopic cylinder 61 is always pressed against the side wall of the grinding wheel mounting base 5 with a certain pressure, providing a balanced locking force from both sides, actively constraining its horizontal degree of freedom, and suppressing the wobble and vibration caused by the grinding force. The parallel spring continuously absorbs high-frequency micro-vibrations, playing a flexible buffering role. The two work together to ensure that the grinding wheel mounting base 5 maintains extremely high stability throughout the entire working cycle.
