Description

Technical Field

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

[0002] During the processing of master alloy bars, there are often defects such as oxide layer, burrs and unevenness on the surface, which need to be treated by a grinder to improve its surface quality and dimensional accuracy. Existing grinders usually use a clamping structure to fix the bar and drive the grinding wheel through a drive motor for grinding. However, the existing equipment has the following problems in practical applications: Limited all-round grinding: Although some equipment is equipped with a rotating structure that allows the rod to rotate 360 ​​degrees, due to the long length of the rod, it still needs to rely on a lateral moving structure to achieve continuous grinding. This design makes it difficult to evenly treat the entire outer surface of the rod during the grinding process.

[0003] Insufficient adaptability: The existing rotating and moving structures can usually only adapt to bars of a single diameter. Even if the clamping structure can be adjusted to accommodate bars of different diameters, the rotating and moving structures are difficult to adapt automatically and often require manual intervention for adjustment. This limitation significantly reduces production efficiency and increases operational complexity when processing bars of multiple specifications and diameters.

[0004] The clamping position affects the grinding effect: When the existing clamping structure clamps the bar, the clamping part cannot be ground, causing this area to become a grinding blind area. In order to complete the surface treatment of the entire bar, the operator needs to adjust the clamping position many times, which not only increases the workload, but also may cause uneven grinding and affect the final product quality.

[0005] Low degree of automation: Existing equipment usually relies on manual operation when adjusting the clamping, rotating and moving structures, and lacks automation functions. This not only increases the labor intensity of operators, but also easily leads to a decrease in grinding accuracy due to human errors, making it difficult to meet the needs of high-precision processing.

[0006] In summary, the existing grinders have obvious deficiencies in adaptability, automation and grinding efficiency, and are difficult to meet the needs 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 DESCRIPTION

[0023] In order to make the purpose, 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 part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The embodiment of the present application provides a grinder for processing master alloy bars, which solves the problem that the existing rotating structure and movable structure 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 movable structure to automatically adapt to the master alloy bars of changed diameters. Even if they can be adjusted, manual auxiliary adjustment is required for adaptation. If a large number of master alloy bars of different diameters need to be processed, the processing efficiency will be greatly reduced.

[0025] The driving unit 5 can drive the rotating unit 2 and the moving unit 3 to respectively drive the rod body 6 to move until the rod body 6 is close to the grinding unit 4. At this time, the grinding unit 4 can be used to grind the outside of the rod body 6. The rotating unit 2 drives the rod body 6 to cooperate with the grinding unit 4 to achieve 360-degree grinding, so that the rod body 6 repeats the process of transverse movement and rotation, thereby achieving all-round grinding of the outside of the rod body 6. There is no blind spot for grinding, and no repeated clamping is required. The supporting unit 1 and the grinding unit 4 can be adjusted according to the diameter of the rod body 6, and the rotating unit 2 and the moving unit 3 can adapt to the diameter of the rod body 6, thereby being able to adapt to master alloy bars of different diameters and perform continuous grinding.

[0026] 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 and specific implementation methods. Example

[0027] The embodiment of the present invention discloses a grinding machine for processing master alloy bars. Figure 1-12 As shown, including: The support unit 1 may be selectively provided with a rod body 6 of different specifications, and the support unit 1 may support and center the rod body 6 therein during the processing and movement; The rotating unit 2 is located on the side of the supporting unit 1 and is arranged outside the rod body 6, and the rotating unit 2 can drive the rod body 6 inside it to rotate along the axis; The moving unit 3 is located on the side of the rotating unit 2 and is arranged outside the rod body 6, and the moving unit 3 can drive the rod body 6 inside it to move along the axis; A grinding unit 4, which is located on one side of the rod body 6 and is capable of grinding the outer side of the rod body 6 of different specifications; The driving unit 5 is disposed 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 respectively drive the rod body 6 to move.

[0028] It should be emphasized that the number of support units 1, rotating units 2, moving units 3, grinding units 4 and driving units 5 can be optionally set, so that when the rod body 6 passes through multiple support units 1, it can be rotated and moved by the rotating unit 2 and the moving unit 3. At this time, the grinding unit 4 is used to grind the outside of the rod body 6. At the same time, if the length of the rod body 6 is large, multiple grinding units 4 can be preset to grind different sections at the same time to improve the grinding efficiency.

[0029] During use, the support unit 1 is first preset according to the diameter of the rod body 6 so that the rod body 6 can be inserted into the support unit 1. At the same time, the support unit 1 supports and centers the rod body 6 inside it. Then, the end of the rod 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 with the rod body 6 and separate the rotating unit 2 from the rod body 6. Then, the moving unit 3 can drive the rod body 6 to move horizontally. Until the rod body 6 is close to the grinding unit 4, the grinding unit 4 can be used to grind the outer side of the rod body 6. At this time, the driving unit 5 is used to make the rotating unit 2 contact with the rod body 6 and separate the moving unit 3 from the rod body 6. Then, the rotating unit 2 drives the rod body 6 to cooperate with the grinding unit 4 to achieve 360-degree grinding. Repeat the above actions, so that the rod body 6 repeats the process of transverse movement and rotation, thereby achieving all-round grinding of the outer side of the rod body 6, without any grinding blind area, and without repeated clamping; The supporting unit 1 and the grinding unit 4 can be adjusted according to the diameter of the rod body 6, while the rotating unit 2 and the moving unit 3 can adapt to the diameter of the rod body 6, thereby being able to adapt to master alloy rods of different diameters and perform continuous grinding.

[0030] Furthermore, the support unit 1 comprises: A first supporting assembly 11; A first adjustment component 12, which is arranged on a side of the first support component 11; A support bar 13 is arranged outside the rod body 6 and is in transmission connection with the first adjustment assembly 12, and a plurality of balls 131 are embedded on one side of the support bar 13 close to the rod body 6, and the plurality of balls 131 fit the rod body 6; The first driving motor 14 is disposed outside the first supporting assembly 11 and is drivingly connected to the first adjusting assembly 12 .

[0031] The first driving motor 14 can be used to drive the first adjusting component 12, and under the action of the first adjusting component 12, the multiple support bars 13 can be driven to move toward the center or outward, so as to adapt to the rod body 6 of different diameters. When the balls 131 in multiple directions are in contact with the rod body 6, the rod body 6 can be supported and centrally positioned. At the same time, the multiple balls 131 can be used to enable the rod body 6 to move laterally and rotate relative to the support bars 13.

[0032] Particularly disclosed, the rotating unit 2 comprises: A second support assembly 21, whose structure is the same as that of the first support assembly 11; The second adjustment component 22 is disposed on the side of the second support component 21 and has the same structure as the first adjustment component 12; A rotating roller 23, which is arranged on the outside of the rod body 6 and is in transmission connection with the second adjusting assembly 22; The transmission assembly 24 is disposed on the second supporting assembly 21 and can drive the rotating roller 23 to rotate.

[0033] Under the action of the second adjustment component 22, multiple rotating rollers 23 can be driven to move toward the center or outward, so as to adapt to rod bodies 6 of different diameters, and under the action of the transmission component 24, the rotating rollers 23 can be driven to rotate. When the rotating rollers 23 are tightly against the outer side of the rod body 6, the rod body 6 can be driven to rotate accordingly.

[0034] Particularly disclosed, the second support assembly 21 comprises: The annular support frame 211 has a bottom support frame 212 fixedly mounted on its bottom; A fixing bar 213, which can be optionally installed on the side of the annular support frame 211, and a through slot is provided inside the fixing bar 213; The movable rod 214 is movably inserted into the slot, and one end of the movable rod 214 extends outward and is connected to the rotating roller 23 .

[0035] The bottom support frame 212 and the annular support frame 211 can effectively support the plurality of fixed bars 213 , and the movable rod 214 is movably inserted into the slot provided inside the fixed bar 213 , so that the movable rod 214 can drive the rotating roller 23 to move when moving.

[0036] Particularly disclosed, the second adjustment component 22 includes: A rotating ring 221 is rotatably arranged on the sides of the annular support frame 211 and the bottom support frame 212. The rotating ring 221 is provided with a plurality of arc grooves 224, and a limiting rod 225 is inserted in the arc groove 224. The end of the limiting rod 225 extends toward the inside of the fixing bar 213 and is fixedly connected to the end of the movable rod 214. The arc-shaped bar 222 is fixedly disposed on the side of the bottom support frame 212, and the rotating ring 221 is in contact with the inner wall of the arc-shaped bar 222; The limiting strip 223 is fixedly disposed on the side of the fixing strip 213, and the rotating ring 221 is in contact with the inner wall of the limiting strip 223; The arc-shaped rack 226 is fixedly connected to the outer side of the rotating ring 221 and is located in the arc-shaped bar 222. The arc-shaped rack 226 is meshedly connected with a transmission gear 227. A rotating rod 228 is fixedly inserted on the inner wall of the transmission gear 227, and the rotating rod 228 is rotatably set on the bottom support frame 212.

[0037] When the rotating rod 228 rotates, the transmission gear 227 at its end can be driven to rotate, and the transmission gear 227 is meshed and connected with the arc-shaped rack 226, so that the arc-shaped rack 226 and the rotating ring 221 rotate as a whole. At this time, the arc-shaped bar 222 and the limit bar 223 limit the rotating ring 221, so that the rotating ring 221 can rotate stably as a whole; When the rotating ring 221 rotates, the multiple arc grooves 224 on its outer side can push the limiting rod 225 on its inner wall to move, and then the limiting rod 225 can move outward or inward according to the rotation direction of the rotating ring 221 and the trajectory of the arc groove 224, which can drive the movable rod 214 to move accordingly, so as to achieve the effect of simultaneously adjusting the positions of multiple rotating rollers 23. The first drive motor 14 cooperates with the first adjustment component 12 to achieve the effect of simultaneously adjusting the positions of multiple support bars 13.

[0038] Specifically disclosed, the transmission assembly 24 includes: A transmission rod 241 is rotatably arranged on the sides of the fixed bar 213 and the rotating roller 23 through a plurality of bearing seats, and a spline groove 2411 is provided on the outer side of the transmission rod 241. The outer side of the transmission rod 241 is slidably connected to a second bevel gear 246 through the spline groove 2411; The movable shaft 242 is fixedly inserted into the rotating roller 23. The ends of the transmission rod 241 and the movable shaft 242 are both fixedly sleeved with a first bevel gear 243, and the two first bevel gears 243 are meshed and connected; The fixing frame 244 is fixedly connected to the side of the fixing bar 213, and the end of the fixing frame 244 is movably sleeved on the outside of the transmission rod 241. The fixing frame 244 is also rotatably connected to the driving rod 245, and the end of the driving rod 245 is fixedly sleeved with the third bevel gear 247, and the second bevel gear 246 and the third bevel gear 247 are meshingly connected.

[0039] 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 transmission-connected between the second driving motor 248 and the driving rod 245 .

[0040] By using the second driving motor 248, when it is working, the driving rod 245 can be driven to rotate through the first belt transmission member 249, and 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, thereby driving the transmission rod 241 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 fits the outer side of the rod body 6, it can drive the rod body 6 to rotate accordingly; When the rotating roller 23 is adjusted in position, the transmission rod 241 can be driven to move accordingly, and 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 rotationally connected to the fixing frame 244, and the end of the fixing frame 244 is fixedly connected to the fixing bar 213, the position of the fixing frame 244 is fixed, so that the second bevel gear 246 will not be displaced under the action of the fixing frame 244. When the transmission rod 241 moves, it will not drive the second bevel gear 246 to move, so that 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.

[0041] In particular, the mobile unit 3 comprises: The fixed frame 31 is located on the outer side of the rod body 6 and the side of the annular support frame 211, and a moving groove 32 is opened on the inner wall of the fixed frame 31, and a bidirectional screw rod 33 is rotatably arranged on the inner wall of the moving groove 32, and two nut blocks 34 are symmetrically threadedly connected to the outer side of the bidirectional screw rod 33, and a rotating cylinder 35 is rotatably connected to the nut block 34, and an extrusion groove is opened on the rotating cylinder 35; A second belt transmission member 36, which is installed between the ends of the two bidirectional screw rods 33 that are located outside; The rotating motor 37 is slidably arranged below the fixed frame 31. An empty slot connected to the movable slot 32 is opened below the fixed frame 31. The output end of the rotating motor 37 extends toward the movable slot 32 through the empty slot, 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.

[0042] The bidirectional screw rod 33 is connected to the nut block 34 in the horizontal direction, and the output end of the rotating motor 37 passes through the nut block 34 in 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 in the vertical direction and is spatially separated from the horizontal layout of the bidirectional screw rod 33 to avoid motion interference. In this embodiment, one of the rotating cylinders 35 is provided with a 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 at the same time, thereby more conveniently driving the rod body 6 to move.

[0043] When the rotating motor 37 is started, its output end drives the rotating cylinder 35 to rotate. The rotating cylinder 35 contacts the rod body 6 through the extrusion groove and generates friction, thereby driving the rod body 6 to move axially. At the same time, when the bidirectional screw 33 rotates, the two rotating cylinders 35 can be driven to move toward or away from each other through the nut block 34. On the one hand, it can adapt to rod bodies 6 of different diameters. On the other hand, when the rod body 6 needs to rotate, the rotating cylinder 35 is separated from the rod body 6, thereby not affecting the rotation of the rod body 6.

[0044] Particularly disclosed, the grinding unit 4 comprises: A base 41, with a slide rail 42 fixedly mounted on the top; The hydraulic cylinder 43 is fixedly connected to the end of the slide rail 42, and the hydraulic cylinder 43 is transmission-connected to the third drive motor 44, the third drive motor 44 is slidably arranged above the slide rail 42, and the output end flange of the third drive motor 44 is connected to the grinding wheel 45, and the grinding wheel 45 is located on the side of the rod body 6.

[0045] The output end of the third drive motor 44 can drive the grinding wheel 45 to rotate, thereby grinding the outer side of the rod body 6. At the same time, the hydraulic cylinder 43 can push the third drive motor 44 to slide on the slide rail 42, thereby adjusting the distance between the grinding wheel 45 and the rod body 6, which is convenient for grinding rod bodies 6 of different diameters.
