Description
Technical Field
[0001] This utility model relates to the field of grinding and polishing equipment, and in particular to a pressure device for grinding and polishing spheres of high-hardness and brittle materials. Background Technology
[0002] High-hardness and brittle material spheres refer to spherical workpieces made of materials with both high hardness and high brittleness. Extremely high requirements are placed on the sphericity, surface roughness, and dimensional accuracy of the spheres. Grinding and polishing pressure devices are special equipment designed for workpiece surface processing. Their function is to apply precisely controllable pressure in the two key processes of grinding and polishing, while coordinating with the movement of the workpiece or grinding wheel, to ensure that the processing force is applied evenly to the workpiece surface. This avoids damage to the workpiece due to excessive pressure and affects processing efficiency due to insufficient pressure, ultimately achieving a balance between workpiece shape accuracy, surface quality, and processing efficiency.
[0003] However, traditional grinding and polishing pressure devices for high-hardness and brittle materials have shortcomings. First, traditional grinding and polishing pressure devices are mostly single clamping structures, and the balls lack a limiting structure during the grinding process, making them prone to displacement and falling off. Second, the grinding debris and dust are easily scattered, which can harm human health, and the dust is difficult to clean up after falling to the ground. Therefore, a grinding and polishing pressure device for high-hardness and brittle materials is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a high-hardness and brittle material sphere grinding and polishing pressure device, which aims to improve the problems of simple clamping structure, lack of limiting structure for the sphere during grinding, easy displacement and fall off, easy dispersion of grinding debris and dust, which poses a threat to human health, and difficulty in cleaning up dust that falls on the ground.

[0018] Reference Figures 1-6This utility model provides an embodiment of a high-hardness, brittle material spherical grinding and polishing pressure device, including a base plate 1. The base plate 1 is the installation foundation of the entire device and can bear the weight of each component. Two support frames 3 are fixedly connected to both sides of the top of the base plate 1. The support frames 3 are used to support the guide plate 10, build a frame for the movement of the grinding wheel 7, and ensure the stable installation of the guide plate 10. The top of the four support frames 3 is fixedly connected to the guide plate 10, which can restrict the movement trajectory of the moving plate 5. It is driven by the cylinder 11 to achieve the desired effect. The grinding wheel 7 is directionally moved by sliding plates 5 connected to the inner walls of the four guide plates 10. The sliding plates 5, which carry the grinding wheel 7, are key components connecting the grinding wheel 7 and the guide plates 10. Support plates 12 are fixedly connected to one side of each of the two support frames 3. The support plates 12 are used to fix the cylinder 11, providing a stable mounting platform for it. Cylinder 11 is fixedly mounted on the top of each of the two support plates 12. Cylinder 11 can push and pull the fixing block 16, providing power for the directional movement of the grinding wheel 7. The output end of cylinder 2 11 is fixedly connected to a fixing block 16 through the support frame 1 3. The fixing block 16 can transmit the power of cylinder 2 11, driving the moving plate 5 to move. One side of the fixing block 16 is fixedly connected to the moving plate 5 located at the rear. The connection between the two can move with the fixing block 16, thereby driving the grinding wheel 7 to adjust its position. A motor 1 4 is fixedly installed on one side of the moving plate 5 located at the front. The motor 1 4 can drive the grinding wheel 7 to rotate, providing power for grinding and polishing the ball. The grinding wheel is rotatably connected between two adjacent moving plates 5 through bearings. 7. When the grinding wheel 7 rotates, it can contact the ball to achieve grinding and polishing of the ball. A dust collection box 14 is fixedly connected to the middle of the top of the base plate 1. The dust collection box 14 is used to store the sucked dust and is the core container for dust collection. A dust collection port 15 is fixedly connected to one side of the top of the dust collection box 14. The dust collection port 15 can expand the dust suction range and facilitate the fan 13 to suck the dust into the dust collection box 14. A fan 13 is fixedly installed at one end of the dust collection box 14. After the fan 13 is started, it can form a negative pressure and suck the dust generated by grinding into the dust collection box 14.
[0019] Reference Figure 3Support frame 22 is fixedly connected to the top center of the base plate 1. Support frame 22 supports multiple components and provides a stable installation base for the ball limiting mechanism. Cylinder 6 is fixedly installed at the top center of support frame 22. Cylinder 6 can push linkage plate 23 to provide power for the movement of baffle 27. Linkage plate 23 is rotatably connected to the output end of cylinder 6. Linkage plate 23 can transmit the power of the cylinder and drive rotating plate 9 to rotate. It is a key component for power transmission. Rotating plate 9 is rotatably connected to one end of linkage plate 23, which can convert the linear motion of cylinder 6 into the rotational motion of rotating plate 9. Rotating plate 24 is fixedly connected to one end of rotating plate 9. The rotating plate 24 can rotate under the drive of the linkage plate 23, and drive the rotating plate 24 to move. Both sides of the rotating plate 24 are rotatably connected to the drive plate 8. The drive plate 8 can rotate with the rotating plate 24, causing the two baffles 27 to move closer or further away from each other. Both drive plates 8 are rotatably connected to one side of the baffles 27, which can move under the drive of the drive plate 8 to limit the ball. Multiple springs 26 are fixedly connected to the inner wall of the bottom of the two baffles 27, which can provide elastic buffer to avoid hard contact damage to the hard and brittle ball. One end of the multiple springs 26 is fixedly connected to the compression plate 25. The compression plate 25 can fit against the ball under the action of the springs 26 to enhance the limiting effect.
[0020] Reference Figure 4 Both support frames 22 are fixedly connected to the top of their respective support frames 22. The support frames 2 are used to support the sprockets 20 and ensure their stable rotation. One of the support frames 2 has a motor 2 17 fixedly mounted on its surface. The motor 2 17 can drive the sprockets 20 to rotate, providing power for the chain 21 to run. The inner walls of both support frames 2 are rotatably connected to the sprockets 20 through bearings. When the sprockets 20 rotate, they can drive the chain 21 to run, indirectly driving the ball to roll. The two sprockets 20 have chains 21 fitted on their surfaces. The chains 21 can carry the ball and drive it to roll, so that the ball can be polished in different positions.
[0021] Reference Figure 4 The extrusion plate 25 is engaged with the inner wall of the bottom of the baffle 27 and can move along the inner wall of the baffle 27 to adapt to the extrusion of balls of different sizes. The top of the baffle 27 is slidably connected to the support frame 22, which guides the movement of the baffle 27 and enables it to move in a straight line.
[0022] Reference Figure 3 and Figure 5 The dust collection port 15 is funnel-shaped, which can increase the dust suction area and improve the dust collection efficiency. The two baffles 27 are located above the chain 21, and their positional relationship can ensure that the ball on the chain 21 is limited.
[0023] Reference Figure 5A dust filter 19 is fitted onto one side of the inner wall of the dust collection box 14. The dust filter 19 can block dust from entering the fan 13 and protect the fan 13. The input end of the fan 13 is connected to the inside of the dust collection box 14 to ensure that the fan 13 can smoothly suck in dust.
[0024] Reference Figure 4 The output end of motor 217 is fixedly connected to sprocket 20. The connection between the two can directly drive sprocket 20 to rotate. The output end of motor 14 is fixedly connected to grinding wheel 7. Motor 14 can directly drive grinding wheel 7 to rotate.
[0025] Reference Figure 1 The bottom end of the guide plate 10 is fixedly connected to a support frame 3 18, which supports the guide plate 10. The bottom end of the support frame 3 18 is fixedly connected to the base plate 1, which can enhance the stability of the guide plate 10 and ensure the precise movement of the grinding wheel 7.
[0026] Working principle: The cylinder 11 pushes and pulls the fixed block 16, thereby driving the moving plate 5 to move within the guide plate 10. Since the grinding wheel 7 is fixedly connected to the moving plate 5 through the bearing, the grinding wheel 7 can move in a directional manner. By starting the motor 4, the grinding wheel 7 rotates through the bearing. When the two grinding wheels 7 approach each other in a certain position, the ball can be polished. When the ball is placed at the middle of the top of the chain 21, the cylinder 6 pushes the linkage plate 23, causing the linkage plate 23 to drive the rotating plate 9 to rotate, thereby driving the rotating plate 24 to rotate. At the same time, it drives the two drive plates 8 to rotate, thereby causing the two baffles 27 to approach each other, changing the distance to limit the ball. At the same time, the baffles 27... Multiple springs 26 and extrusion plates 25 are provided at the bottom to provide elastic support and prevent hard contact from causing extrusion damage to the high-hardness and brittle material sphere. This prevents the sphere from shifting and falling during processing, thus improving stability. By starting the motor 17, the sprocket 20 rotates through the bearing, which in turn drives the chain 21 to run on the surface of the two sprockets 20. This causes the sphere to roll between the top surface of the chain 21 and the two baffles 27, thereby achieving grinding and polishing of the sphere in different directions. In addition, by installing a fan 13 on one side of the dust collection box 14, when the fan 13 is started, the grinding dust is sucked into the dust collection box 14 through the dust collection port 15. The dust is prevented from entering the fan 13 by the dust screen 19, thus achieving dust collection.
