Description

Technical Field

[0001] The present invention relates to the technical field of grinding equipment, and particularly to a grinding machine for processing master alloy bars. Background Art

[0002] During the processing of master alloy bars, defects such as oxide layers, burrs, and unevenness often exist on the surface, and surface treatment is required by a grinding machine to improve its surface quality and dimensional accuracy. Existing grinding machines usually use a clamping structure to fix the bar and drive a grinding wheel to perform grinding through a driving motor. However, the existing equipment has the following problems in practical applications:

[0003] Limited all-round grinding: Although some equipment is equipped with a rotating structure to enable the bar to rotate 360 degrees, due to the long length of the bar, a transverse movement structure is still required to achieve continuous grinding. This design makes it difficult to uniformly process the entire outer surface of the bar during grinding.

[0004] Insufficient adaptability: Existing rotating and moving structures usually can only adapt to bars of a single diameter. Even if the clamping structure can be adjusted to adapt to bars of different diameters, the rotating and moving structures are difficult to automatically adapt, and manual intervention is often required for adjustment. This limitation significantly reduces the production efficiency and increases the operation complexity when processing bars of multiple specifications and diameters.

[0005] The clamping position affects the grinding effect: When the existing clamping structure clamps the bar, the clamped part cannot be ground, resulting in this area becoming a grinding blind spot. To complete the surface treatment of the entire bar, the operator needs to adjust the clamping position multiple times, which not only increases the workload but also may cause uneven grinding and affect the final product quality.

[0006] Low degree of automation: When adjusting the clamping, rotating, and moving structures of existing equipment, manual operation is usually relied on, lacking automation functions. This not only increases the labor intensity of the operator but also easily leads to a decrease in grinding accuracy due to human errors, making it difficult to meet the requirements of high-precision processing.

[0007] In summary, existing grinding machines have obvious deficiencies in terms of adaptability, degree of automation, and grinding efficiency, and are difficult to meet the requirements of high efficiency, high precision, and multi-specification processing in modern industrial production. Therefore, there is an urgent need for a device that can automatically adapt to master alloy bars of different diameters and achieve continuous and efficient grinding to solve the above problems.

Detailed implementation manners

[0067] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0068] In an embodiment of the present application, by providing a grinding machine for processing master alloy bars, the problem is solved that existing rotating structures and moving structures are usually set for master alloy bars of a single diameter. Even if the clamping structure is convenient for clamping master alloy bars of different diameters, it is difficult for the rotating structure and the moving structure to automatically adapt to master alloy bars with changed diameters. Even if adjustment can be made, manual assistance is required for adaptation. If a relatively large number of master alloy bars of different diameters need to be processed, the processing efficiency will be greatly reduced.

[0069] The driving unit 5 can drive the rotating unit 2 and the moving unit 3 to drive the bar body 6 to move respectively until the bar body 6 approaches the grinding unit 4. At this time, the grinding unit 4 can grind the outer side of the bar body 6. The rotating unit 2 drives the bar body 6 to cooperate with the grinding unit 4 to achieve 360-degree grinding, so that the bar body 6 repeats the process of horizontal movement and rotation. Furthermore, all-round grinding of the outer side of the bar body 6 can be realized, there is no grinding blind area, no repeated clamping is required, and the support unit 1 and the grinding unit 4 can be adjusted according to the diameter of the bar body 6, while the rotating unit 2 and the moving unit 3 can adapt to the diameter of the bar body 6. Therefore, it can adapt to master alloy bars of different diameters and carry out continuous grinding work.

[0070] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners. Embodiment

[0071] An embodiment of the present invention discloses a grinding machine for processing master alloy bars. As shown in the attached Figures 1-12 drawing, it includes:

[0072] A support unit 1, which can optionally be provided with bar bodies 6 of different specifications inside, and the support unit 1 can support and center-position the bar body 6 inside during the processing and movement.

[0073] A rotating unit 2, which is located on the side of the support unit 1 and is arranged outside the bar body 6, and the rotating unit 2 can drive the bar body 6 inside it to rotate along the axis.

[0074] A moving unit 3, which is located on the side of the rotating unit 2 and is arranged outside the bar body 6, and the moving unit 3 can drive the bar body 6 inside it to move along the axis.

[0075] A grinding unit 4, which is located on one side of the bar body 6 and can grind the outer sides of bar bodies 6 of different specifications.

[0076] A driving unit 5 is provided between the rotating unit 2 and the moving unit 3, and the driving unit 5 can drive the rotating unit 2 and the moving unit 3 to drive the bar body 6 to move respectively.

[0077] It should be emphasized that the quantities of the supporting unit 1, the rotating unit 2, the moving unit 3, the grinding unit 4 and the driving unit 5 can be set optionally, so that when the bar body 6 passes through multiple supporting units 1, it can be rotated and moved by the rotating unit 2 and the moving unit 3. At this time, the outer side of the bar body 6 is ground by the grinding unit 4. Meanwhile, if the length of the bar body 6 is relatively large, multiple grinding units 4 can be preset to grind different sections simultaneously to improve the grinding efficiency.

[0078] During the use process, first, according to the diameter of the bar body 6, the supporting unit 1 is preset so that the bar body 6 can be inserted into the supporting unit 1. Meanwhile, the supporting unit 1 supports and centers the bar body 6 inside it. Then, the end of the bar body 6 is inserted into the rotating unit 2 and the moving unit 3. At this time, the driving unit 5 is used to make the moving unit 3 contact the bar body 6 and make the rotating unit 2 separate from the bar body 6. Then, the moving unit 3 can drive the bar body 6 to move in the horizontal direction;

[0079] Until the bar body 6 is close to the grinding unit 4. At this time, the grinding unit 4 can grind the outer side of the bar body 6. At this time, the driving unit 5 is used to make the rotating unit 2 contact the bar body 6 and make the moving unit 3 separate from the bar body 6. Then, the rotating unit 2 drives the bar body 6 to cooperate with the grinding unit 4 to achieve 360-degree grinding. Repeat the above actions to make the bar body 6 repeat the process of horizontal movement and rotation, so as to realize the all-round grinding of the outer side of the bar body 6, there is no grinding blind area, and there is no need for repeated clamping;

[0080] Moreover, the supporting unit 1 and the grinding unit 4 can be adjusted according to the diameter of the bar body 6, while the rotating unit 2 and the moving unit 3 can adapt to the diameter of the bar body 6, so as to be able to adapt to different-diameter master alloy bars and carry out continuous grinding work.

[0081] Furthermore, the supporting unit 1 includes:

[0082] A first supporting component 11;

[0083] A first adjusting component 12, which is arranged on the side of the first supporting component 11;

[0084] A supporting bar 13, which is arranged on the outer side of the bar body 6 and is in transmission connection with the first adjusting component 12. A plurality of balls 131 are embedded on the side of the supporting bar 13 close to the bar body 6, and the plurality of balls 131 are in contact with the bar body 6;

[0085] The first drive motor 14 is arranged outside the first support assembly 11 and is in transmission connection with the first adjustment assembly 12.

[0086] The first drive motor 14 can drive the first adjustment assembly 12. Under the action of the first adjustment assembly 12, a plurality of support bars 13 can be driven to move towards the center or move outwards, so as to adapt to bar bodies 6 with different diameters. When the balls 131 in multiple directions are in contact with the bar body 6, the bar body 6 can be supported and centered, and at the same time, the bar body 6 can be translated and rotated relative to the support bars 13 by means of the plurality of balls 131.

[0087] Specifically disclosed, the rotating unit 2 includes:

[0088] A second support assembly 21, whose structure is the same as that of the first support assembly 11;

[0089] A second adjustment assembly 22, which is arranged on the side of the second support assembly 21 and has the same structure as the first adjustment assembly 12;

[0090] A rotating roller 23, which is arranged outside the bar body 6 and is in transmission connection with the second adjustment assembly 22;

[0091] A transmission assembly 24, which is arranged on the second support assembly 21 and can drive the rotating roller 23 to rotate.

[0092] Under the action of the second adjustment assembly 22, a plurality of rotating rollers 23 can be driven to move towards the center or move outwards, so as to adapt to bar bodies 6 with different diameters. Under the action of the transmission assembly 24, the rotating roller 23 can be driven to rotate. When the rotating roller 23 is in close contact with the outer side of the bar body 6, the bar body 6 can be driven to rotate accordingly.

[0093] Specifically disclosed, the second support assembly 21 includes:

[0094] An annular support frame 211, at the bottom of which a bottom support frame 212 is fixedly installed;

[0095] A fixing bar 213, which can be selectively installed on the side of the annular support frame 211. A through slot is formed inside the fixing bar 213;

[0096] A movable rod 214, which is movably inserted into the slot, and one end of the movable rod 214 extends outwards and is connected to the rotating roller 23.

[0097] The bottom support frame 212 and the annular support frame 211 can effectively support a plurality of fixing bars 213. At the same time, the movable rod 214 is movably inserted into the slot formed inside the fixing bar 213, so that the movable rod 214 can drive the rotating roller 23 to move accordingly when it moves.

[0098] Specifically disclosed, the second adjusting component 22 includes:

[0099] A rotating ring 221, which is rotatably arranged on the side surfaces of the annular support frame 211 and the bottom support frame 212. The rotating ring 221 is provided with a plurality of arc-shaped grooves 224, and a limiting rod 225 is inserted into the arc-shaped groove 224. The end of the limiting rod 225 extends towards the inside of the fixing bar 213 and is fixedly connected to the end of the movable rod 214;

[0100] An arc-shaped strip 222, which is fixedly arranged on the side surface of the bottom support frame 212, and the rotating ring 221 is in contact with the inner wall of the arc-shaped strip 222;

[0101] A limiting strip 223, which is fixedly arranged on the side surface of the fixing bar 213, and the rotating ring 221 is in contact with the inner wall of the limiting strip 223;

[0102] An arc-shaped rack 226, which is fixedly connected to the outside of the rotating ring 221 and is located in the arc-shaped strip 222. The arc-shaped rack 226 is meshed with a transmission gear 227. A rotating rod 228 is fixedly inserted into the inner wall of the transmission gear 227, and the rotating rod 228 is rotatably arranged on the bottom support frame 212.

[0103] When the rotating rod 228 rotates, it can drive the transmission gear 227 at its end to rotate. Since the transmission gear 227 is meshed with the arc-shaped rack 226, the arc-shaped rack 226 and the rotating ring 221 as a whole rotate. At this time, the arc-shaped strip 222 and the limiting strip 223 limit the rotating ring 221, so that the rotating ring 221 can rotate stably as a whole;

[0104] When the rotating ring 221 rotates, the plurality of arc-shaped grooves 224 on its outer side can push the limiting rod 225 on its inner wall to move. Then, according to the rotation direction of the rotating ring 221 and the trajectory of the arc-shaped groove 224, the limiting rod 225 can move outwards or inwards, which can drive the movable rod 214 to move accordingly, achieving the effect of simultaneously adjusting the positions of a plurality of rotating rollers 23. Then, the first driving motor 14 and the first adjusting component 12 can achieve the effect of simultaneously adjusting the positions of a plurality of support bars 13.

[0105] Specifically disclosed, the transmission component 24 includes:

[0106] The transmission rod 241 is rotatably arranged on the sides of the fixed strip 213 and the rotating roller 23 through a plurality of bearing seats. A spline groove 2411 is formed on the outer side of the transmission rod 241, and a second bevel gear 246 is slidably connected to the outer side of the transmission rod 241 through the spline groove 2411;

[0107] The movable shaft 242 is fixedly inserted into the inside of the rotating roller 23. First bevel gears 243 are fixedly sleeved on the ends of the transmission rod 241 and the movable shaft 242, and the two first bevel gears 243 are meshed and connected;

[0108] The fixed frame 244 is fixedly connected to the side of the fixed strip 213. The end of the fixed frame 244 is movably sleeved on the outer side of the transmission rod 241. A driving rod 245 is also rotatably connected to the fixed frame 244. A third bevel gear 247 is fixedly sleeved on the end of the driving rod 245, and the second bevel gear 246 and the third bevel gear 247 are meshed and connected.

[0109] Furthermore, a second driving motor 248 is fixedly connected to the side of the annular support frame 211, and a first belt transmission member 249 is connected in a transmission manner between the second driving motor 248 and the driving rod 245.

[0110] By using the provided second driving motor 248, when it works, the driving rod 245 can be driven to rotate through the first belt transmission member 249. The third bevel gear 247 at the end of the driving rod 245 is meshed and connected with the second bevel gear 246 on the outer side of the transmission rod 241, so that the transmission rod 241 can be driven to rotate. At this time, the transmission rod 241 can drive the rotating roller 23 to rotate through the two first bevel gears 243 and the movable shaft 242. When the rotating roller 23 is in contact with the outer side of the bar body 6, the bar body 6 can be driven to rotate accordingly;

[0111] When the position of the rotating roller 23 is adjusted, the transmission rod 241 can be driven to move accordingly. The outer side of the transmission rod 241 is connected to the second bevel gear 246 through the spline groove 2411. Since the second bevel gear 246 is rotatably connected to the fixed frame 244, and at the same time the end of the fixed frame 244 is fixedly connected to the fixed strip 213, the position of the fixed frame 244 is fixed. Therefore, the second bevel gear 246 will not be displaced under the action of the fixed frame 244. Then, when the transmission rod 241 moves, it will not drive the second bevel gear 246 to move. Thus, the driving rod 245 can still drive the transmission rod 241 to rotate through the third bevel gear 247 and the second bevel gear 246.

[0112] Specifically disclosed, the moving unit 3 includes:

[0113] The fixed frame 31 is located on the outer side of the bar body 6 and the side surface of the annular support frame 211. A moving groove 32 is formed on the inner wall of the fixed frame 31. A bidirectional lead screw 33 is rotatably arranged on the inner wall of the moving groove 32. Two nut blocks 34 are symmetrically and threadedly connected to the outer side of the bidirectional lead screw 33. A rotating cylinder 35 is rotatably connected to the nut block 34, and an extrusion groove is formed on the rotating cylinder 35.

[0114] The second belt transmission member 36 is installed between the outer ends of the two bidirectional lead screws 33.

[0115] The rotating motor 37 is slidably arranged below the fixed frame 31. An empty groove communicating with the moving groove 32 is formed below the fixed frame 31. The output end of the rotating motor 37 extends through the empty groove towards the moving groove 32, and the output end of the rotating motor 37 passes through the nut block 34 and is fixedly connected to the end of the rotating cylinder 35.

[0116] The bidirectional lead screw 33 is horizontally connected to the nut block 34, and the output end of the rotating motor 37 passes through the nut block 34 from the vertical direction and is fixedly connected to the end of the rotating cylinder 35. The output end of the rotating motor 37 passes through the nut block 34 from the vertical direction, forming a spatial separation from the horizontal layout of the bidirectional lead screw 33, avoiding movement interference. In this embodiment, one of the rotating cylinders 35 is provided with the rotating motor 37. In actual settings, two rotating motors 37 can be symmetrically arranged. The two rotating motors 37 drive the two rotating cylinders 35 to rotate simultaneously, thereby more conveniently driving the bar body 6 to move.

[0117] When the rotating motor 37 is started, its output end drives the rotating cylinder 35 to rotate. The rotating cylinder 35 contacts the bar body 6 through the extrusion groove and generates frictional force, thereby driving the bar body 6 to move axially. At the same time, when the bidirectional lead screw 33 rotates, it can drive the two rotating cylinders 35 to move towards or away from each other through the nut block 34. On the one hand, it can adapt to bar bodies 6 of different diameters.
