Description

Technical Field

[0001] The utility model relates to the technical field of steel ball processing, in particular to a steel ball grinding device. Background Art

[0002] Steel balls are important basic components. Especially, precision industrial steel balls play a huge role in the development of the national economy. Under some special conditions, steel balls made of special materials are often required to complete the functions required in different environments. Some of these special material steel balls have been widely used in various fields of the national economy. Their popularization and application not only promote the development of the steel ball production industry, but also promote the technological development and scientific and technological progress of related industries. Steel balls are divided into grinding steel balls, forging steel balls, and casting steel balls according to the production and processing technology, and are divided into stainless steel balls, carbon steel balls, alloy balls, etc. according to the processing materials.

[0003] For example, the Chinese utility model patent with the patent number CN220296704U provides a grinding device for steel ball production, including a water tank. The top of both sides of the inner cavity of the water tank is fixedly connected with slideways. A filter plate is slidably connected to the inner side of the slideways. The bottom of the back of the water tank is fixedly installed with a water pump. The input end of the water pump is fixedly connected with a second pipeline. The output end of the water pump is fixedly connected with a first pipeline. One end of the first pipeline is fixedly connected with a spray head. The top of both sides of the water tank is fixedly connected with vertical plates. An electric telescopic rod is fixedly connected to the inner side of the vertical plates. Through the settings of the water tank, the water pump, the first pipeline, the spray head and the second pipeline, the utility model solves the problem that the existing grinding device does not have the function of rapid cooling. Since the temperature of the steel balls after grinding is relatively high, it is inconvenient to take them, and the natural cooling time is relatively long, resulting in the inability of the device to carry out subsequent work, greatly reducing the work efficiency.

[0004] Although the above device shows a certain effect in rapidly cooling steel balls, its design has certain limitations. Specifically, although the device can drive the steel balls to rotate through the cooperation of the motor and the rotating rod, its rotation angle is strictly limited, which results in that the steel balls can only perform a single rotation movement in the horizontal direction. When it is necessary to grind the lower half of the steel balls, the operator has to manually turn the steel balls. This process not only takes time and effort, but also greatly drags down the grinding efficiency of the steel balls and affects the overall production progress. Summary of the Utility Model

[0005] The utility model discloses a steel ball grinding device, which solves the problem that in the process of using the traditional steel ball grinding device, due to the limited rotation angle of the steel balls, only a single rotation in the horizontal direction can be realized, resulting in the need to manually turn the steel balls when grinding the lower half, which is time-consuming and laborious and affects the grinding efficiency and production progress.

[0006] To solve the above technical problems, the following technical solutions are specifically adopted in the present utility model:

[0007] A steel ball grinding device includes a horizontally arranged workbench. A fixed seat is fixed on the top surface of the workbench. An arc-shaped placement groove is formed at the center of the top surface of the fixed seat, and the distance from the bottommost end of the placement groove to the center of the top surface of the fixed seat is less than the radius of the steel ball. A number of rolling balls are evenly and rotatably connected to the top edge of the placement groove. The number of rolling balls are all on the same horizontal plane and are distributed in a ring shape; A support frame is also fixed on the top surface of the workbench. A grinding component and an angle adjustment component are provided on the support frame and are respectively located on both sides of the fixed seat. When the steel ball is placed in the placement groove, the center of the steel ball, the central axis of the grinding component, and the central axis of the angle adjustment component are all at the same horizontal height; A fixing component is also provided on the support frame above the fixed seat. The projection of the fixing component in the vertical direction coincides with the center of the fixed seat. The fixing component is used for fixing and limiting the top of the steel ball; The angle adjustment component includes a horizontally arranged fixed cylinder rotatably connected to one side of the support frame. The end of the fixed cylinder not connected to the support frame is open and extends towards the grinding component. A horizontal automatic push rod is fixed inside the fixed cylinder. The output end of the automatic push rod is fixed with a U-shaped frame located outside the fixed cylinder. An adjustment wheel is rotatably connected inside the U-shaped frame. A motor for driving the adjustment wheel to rotate around its own axis is fixed on the U-shaped frame. A driving component for driving the fixed cylinder to rotate around its own axis is provided on the support frame.

[0008] Compared with the prior art, the present utility model has the following beneficial effects:

[0009] Place the steel ball to be processed in the placement groove of the fixed seat. Due to the setting that the distance from the bottommost end of the placement groove to the center of the top surface of the fixed seat is less than the radius of the steel ball, more than half of the steel ball will be located outside the placement groove. And since several rolling balls are evenly rotatably connected at the top edge of the placement groove, the part of the steel ball located in the placement groove will be in contact with the rolling balls. Subsequently, use the fixing component to fix and limit the top of the steel ball, so that the steel ball can be stably placed between the fixed seat and the fixing component. Then, the grinding component can be used to grind one side surface of the steel ball; when it is necessary to grind other parts of the surface of the steel ball, start the automatic push rod. The output end of the automatic push rod drives the U-shaped frame to move horizontally towards the steel ball, and then the adjusting wheel can be driven to move horizontally towards the steel ball. At the same time, use the motor to drive the adjusting wheel to rotate around its own axis. When the adjusting wheel is in contact with the surface of the steel ball, since the bottom of the steel ball is in contact with several rolling balls at this time, the steel ball can be smoothly driven to rotate in the placement groove, and the rotation direction is opposite to that of the adjusting wheel. While the steel ball is rotating, the grinding component can be used to continuously grind the surface of the steel ball, and the uniform grinding operation of the steel ball in the current rotation direction can be realized; when it is necessary to adjust the rotation angle of the steel ball, use the driving component to drive the fixed cylinder to rotate around its own axis, so that the adjusting wheel deviates from the initial position and forms a certain angle with the initial rotation direction, thereby driving the steel ball to rotate in different directions. In this way, through the rotation of the fixed cylinder, any position on the surface of the steel ball can be ground, and thus the surface of the steel ball can be ground more evenly. The utility model has strong practicability. By setting the placement groove, rolling balls, adjusting wheel, motor, automatic push rod, fixed cylinder and driving component, without manual operation, the rotation angle of the steel ball can be automatically adjusted, so that any position on the surface of the steel ball can be ground, and thus the surface of the steel ball can be ground more evenly, effectively improving the grinding efficiency and grinding quality.

Specific implementation mode

[0018] The following will describe in detail the specific content of the utility model in conjunction with the drawings and embodiments.

[0019] As Figure 1 , Figure 2 and Figure 6 shown, the utility model provides a steel ball grinding device, which includes a horizontally arranged workbench 1. A fixing seat 2 is fixed on the top surface of the workbench 1. An arc-shaped placing groove 21 is opened at the center of the top surface of the fixing seat 2, and the distance from the bottommost end of the placing groove 21 to the center of the top surface of the fixing seat 2 is less than the radius of the steel ball. A plurality of balls 22 are evenly and rotatably connected to the top edge of the placing groove 21. The plurality of balls 22 are all on the same horizontal plane and are distributed in a ring shape; A support frame 3 is also fixed on the top surface of the workbench 1. A grinding assembly and an angle adjustment assembly are provided on the support frame 3 and are respectively located on both sides of the fixing seat 2. When the steel ball is placed in the placing groove 21, the center of the steel ball, the central axis of the grinding assembly, and the central axis of the angle adjustment assembly are all at the same horizontal height; A fixing assembly is also provided on the support frame 3 and is located above the fixing seat 2. The vertical projection of the fixing assembly coincides with the center of the fixing seat 2; The angle adjustment assembly includes a fixing cylinder 6 that is rotatably connected to one side of the support frame 3 and is horizontally arranged. One end of the fixing cylinder 6 that is not connected to the support frame 3 is open and extends towards the grinding assembly. A horizontal automatic push rod 61 is fixed inside the fixing cylinder 6. The output end of the automatic push rod 61 is fixed with a U-shaped frame 62 located outside the fixing cylinder 6. An adjusting wheel 63 is rotatably connected inside the U-shaped frame 62. A motor 64 for driving the adjusting wheel 63 to rotate around its own axis is fixed on the U-shaped frame 62. A driving assembly for driving the fixing cylinder 6 to rotate around its own axis is provided on the support frame 3. Further, the adjusting wheel 63 can be made of rubber material with a large coefficient of friction, so that the adjusting wheel 63 can more easily drive the steel ball to rotate, and at the same time, it will not scratch the surface of the steel ball and affect the product quality.

[0020] As Figure 1 and Figure 6 shown, the driving component includes a toothed ring 7 fixedly connected to one end of the fixed cylinder 6 close to the support frame 3 and vertically arranged. External teeth are evenly arranged on the outer side of the toothed ring 7. A gear 71 is meshed with the toothed ring 7. A stepping motor 72 for driving the gear 71 to rotate around its own axis is arranged on the support frame 3. When it is necessary to adjust the rotation angle of the steel ball, the stepping motor 72 is started. The output end of the stepping motor 72 drives the gear 71 to rotate around its own axis, and the whole fixed cylinder 6 can be driven to rotate through the toothed ring 7, so that the adjusting wheel 63 deviates from the initial position and forms a certain angle with the initial rotation direction, and further enables the steel ball to rotate towards different angles; in the actual operation process, the stepping motor 72 can also be used to control the gear 71 to rotate intermittently at uniform intervals, so that the steel ball can stay for the same time in each rotation direction to ensure that the surface of the steel ball can be polished more evenly.

[0021] As Figure 1 and Figure 4 shown, the grinding component includes a first cylinder 4 arranged horizontally opposite to the fixed cylinder 6. The output end of the first cylinder 4 is fixed with a mounting seat 41. A vertical grinding disc 42 is rotatably connected to one end of the mounting seat 41 away from the first cylinder 4. A grinding motor 43 for driving the grinding disc 42 to rotate around its own axis is arranged in the mounting seat 41. The first cylinder 4 is started to drive the grinding disc 42 to move horizontally towards the fixed cylinder 6, so that the grinding disc 42 is in contact with the surface of the steel ball. The grinding motor 43 is started to drive the grinding disc 42 to rotate around its own axis, and the surface of the steel ball can be ground.

[0022] As Figure 1 and Figure 5 shown, the fixing component includes a limiting plate 51 horizontally arranged above the fixed seat 2. An arc-shaped fixing groove 52 is opened at the center of the bottom surface of the limiting plate 51. A second cylinder 5 for driving the limiting plate 51 to approach or move away from the fixed seat 2 is arranged on the support frame 3. When the steel ball is placed in the placing groove 21 of the fixed seat 2, the second cylinder 5 is started. The output end of the second cylinder 5 drives the limiting plate 51 to approach the fixed seat 2. Since the arc-shaped fixing groove 52 is opened at the center of the bottom surface of the limiting plate 51, the top of the steel ball can be tightly attached to the arc-shaped fixing groove 52, so as to effectively limit and fix the steel ball and prevent the steel ball from falling out of the fixed seat 2 during the processing; in addition, in the actual production process, when it is necessary to control the rotation of the steel ball, the second cylinder 5 can be used to control the limiting plate 51 to move slightly upward on the basis of being in close contact with the steel ball, so that the steel ball can rotate freely while being restricted by the limiting plate 51, making the processing process more convenient.

[0023] AsFigure 1 , Figure 2 and Figure 7 As shown in Figure 1 , Figure 2 and Figure 7 , the top surface of the fixed seat 2 is open, and a hollow plate 8 is provided at the open part of the top surface of the fixed seat 2. The bottom end of the fixed seat 2 penetrates through the workbench 1 and extends below the workbench 1. A blower 81 is connected to the bottom end of the fixed seat 2, and a filter plate 83 is detachably connected inside the fixed seat 2. The blower 81 is used to adsorb the debris generated during the grinding of the steel balls. Since the hollow plate 8 is provided at the open part of the top surface of the fixed seat 2, the debris can fall into the fixed seat 2 through the hollow plate 8, so as to collect and centrally process the debris to prevent it from polluting the environment. And due to the setting of the filter plate 83, it can prevent the debris from being sucked into the blower 81 and causing damage to the blower 81.

[0024] As Figure 1 and Figure 7 As shown in Figure 1 and Figure 7 , sliding rails 82 are respectively fixed on both sides of the inner bottom of the fixed seat 2. Both sides of the filter plate 83 are respectively slidably connected to the two sliding rails 82. A box door 9 is hinged to the part of the fixed seat 2 located below the workbench 1, and a handle 91 is fixed on the box door 9. By opening the box door 9 through the handle 91, the debris collected in the fixed seat 2 can be processed; and the setting of the sliding rails 82 can facilitate the staff to disassemble the filter plate 83, so as to realize the cleaning and replacement operation of the filter plate 83.

[0025] As Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , an annular connecting rod 23 is provided at the top edge of the placement groove 21. A number of balls 22 are sequentially sleeved on the connecting rod 23. A number of support rods 24 are provided on the placement groove 21, and one end of each of the number of support rods 24 is fixedly connected to the connecting rod 23. The number of support rods 24 evenly divides the number of balls 22 into several groups. The settings of the connecting rod 23 and the support rods 24 can play a role in fixing the balls 22, and at the same time, it will not affect the rotation of the balls 22.

[0026] As Figure 2 As shown in Figure 2 , a number of support bars 211 are fixed inside the fixed seat 2, and one end of each of the support bars 211 is fixed to the outer wall of the placement groove 21. The support bars 211 can play a role in fixing the placement groove 21. Further, when the fixed seat 2 is square, the support bars 211 can be arranged at the four corners to reduce the influence on the adsorption of debris.

[0027] As Figure 1 As shown in Figure 1 , a support 11 is fixed to the bottom surface of the workbench 1. The support 11 can support the entire device, making the use of the entire device more convenient.

[0028] During use, place the steel ball to be processed in the placement groove 21 of the fixed seat 2. Due to the distance from the bottommost end of the placement groove 21 to the center of the top surface of the fixed seat 2 being less than the radius of the steel ball, more than half of the steel ball will be outside the placement groove 21. And since a number of rolling balls 22 are evenly rotatably connected to the top edge of the placement groove 21, the part of the steel ball inside the placement groove 21 will come into contact with the rolling balls 22. Subsequently, start the second cylinder 5, and the output end of the second cylinder 5 drives the limiting plate 51 to approach the fixed seat 2. Since an arc-shaped fixing groove 52 is provided at the center of the bottom surface of the limiting plate 51, the top of the steel ball can be closely attached to the arc-shaped fixing groove 52, thereby fixing and limiting the top of the steel ball, so that the steel ball can be stably placed between the fixed seat 2 and the limiting plate 51. Then, start the first cylinder 4 to drive the grinding disc 42 to horizontally move towards the fixed cylinder 6, so that the grinding disc 42 is in contact with the surface of the steel ball. Start the grinding motor 43 to drive the grinding disc 42 to rotate around its own axis, and the surface of the steel ball can be ground. When it is necessary to grind other parts of the surface of the steel ball, start the automatic push rod 61, and the output end of the automatic push rod 61 drives the U-shaped frame 62 to horizontally move towards the steel ball, and then the adjusting wheel 63 can be driven to horizontally move towards the steel ball. At the same time, use the motor 64 to drive the adjusting wheel 63 to rotate around its own axis. When the adjusting wheel 63 is in contact with the surface of the steel ball, at this time, since the bottom of the steel ball is in contact with a number of rolling balls 22, the steel ball can be smoothly driven to rotate in the placement groove 21, and the rotation direction is opposite to that of the adjusting wheel 63. While the steel ball is rotating, the surface of the steel ball can be continuously ground by the grinding disc 42, and uniform grinding of the steel ball in the current rotation direction can be achieved. When it is necessary to control the rotation angle of the steel ball, start the stepping motor 72, and the output end of the stepping motor 72 drives the gear 71 to rotate around its own axis, and then the entire fixed cylinder 6 can be driven to rotate through the toothed ring 7, so that the adjusting wheel 63 deviates from the initial position and forms a certain angle with the initial rotation direction, thereby driving the steel ball to rotate in different directions. In this way, through the rotation of the fixed cylinder 6, any position on the surface of the steel ball can be ground, and thus the surface of the steel ball can be ground more evenly.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
