Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically to an aluminum alloy grinding device. Background Technology

[0002] In the process of polishing aluminum alloy tubes, polishing equipment is used to save labor. This equipment can improve polishing efficiency and is not only faster but also has a better polishing effect compared with manual polishing. However, this equipment also has certain drawbacks, namely, it cannot polish multiple sets of aluminum alloy tubes at the same time.

[0003] To solve the above-mentioned technical problems, some grinding equipment uses multiple grinding structures. However, this method results in a large overall size of the device and is inconvenient for centralized grinding. In the grinding of aluminum alloy tubes, grinding is usually achieved by rotating the grinding belt. Existing methods typically involve clamping the aluminum alloy tube and pushing it towards the grinding belt. However, if multiple sets are used, it is necessary to consider how to grind multiple sets of aluminum alloy tubes without interfering with each other. This aspect is the key to the entire device. Nowadays, grinding equipment usually uses a single-tube grinding method. Although the structure of the device is simple, its efficiency is greatly reduced compared to devices that grind multiple sets of tubes simultaneously.

[0004] In order to solve the above-mentioned technical problems, realize the ability to grind multiple sets of aluminum alloy tubes simultaneously without affecting adjacent aluminum alloy tubes, and improve the grinding efficiency of aluminum alloy tubes, an aluminum alloy grinding device is proposed to solve the technical problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy grinding device, including a worktable, a feeding structure on the upper surface of the worktable, and a housing plate bolted to the upper surface of the worktable. A grinding structure capable of simultaneous grinding of multiple sets is also installed on the inner side of the housing plate. This grinding structure includes a drive structure and grinding components, which include a rotating shaft, a bearing seat, a pulley, and a grinding belt. Three sets of openings are triangularly formed on the left and right sides of the housing plate, and a bearing seat is installed at each of these openings. The inner ring of the bearing seat is connected to the rotating shaft, which is located inside the housing plate. Each of the rotating shafts is equipped with a pulley, and a grinding belt is fitted on the surface of two adjacent sets of pulleys. The feeding structure holds at least three sets of aluminum alloy tubes, and one end of each set of aluminum alloy tubes is located in the middle of the corresponding grinding belt surface. The feeding structure consists of a moving structure, a rotating structure, and a clamping structure. The aluminum alloy tubes are clamped by the clamping structure. The driving structure is connected to one of the rotating shafts and rotates through the rotating structure. The moving structure drives the rotating structure to move. The inner side of the outer shell plate is also provided with a support structure to support the grinding belt. The surface of the aluminum alloy tube contacts the surface of the grinding belt and is pressed against the surface of the grinding belt in the direction of the grinding belt.

[0007] Further, the support structure includes a mounting plate, a connecting plate, an arc-shaped plate, a insert shaft, a bearing I, and a pulley II, as described above. Two sets of mounting plates are installed on the top surface of the inner side of the outer shell plate, and another set of mounting plates is installed on the bottom surface of the inner side of the outer shell plate. A connecting plate is fixedly installed on the surface of the mounting plate, and an arc-shaped plate is installed on the inner side of the connecting plate by bolts. An opening is provided on the surface of the arc-shaped plate, and a bearing I is installed in the opening. The inner ring of the bearing I is connected to an insert shaft, and a pulley II is installed on the surface of the insert shaft and contacts the grinding belt.

[0008] Furthermore, the drive structure includes a servo motor, pulley three, and a transmission belt; the servo motor is mounted on the rear side of the outer shell plate, and pulley three is mounted on both the output end and the surface of the rotating shaft one, with the transmission belt sleeved on the surfaces of the two sets of pulley three.

[0009] As a preferred technical solution, the moving structure includes a guide rail, a rack, a moving seat, and a stepper motor; the guide rail and the rack are both mounted on the upper surface of the worktable, and the moving seat is movably mounted on the guide rail. A stepper motor is mounted on the bottom inner side of the moving seat, and the output end of the stepper motor is connected to a gear and meshes with the rack to form a transmission. The rotating structure is mounted on the moving seat.

[0010] Furthermore, the rotating structure includes a mounting base one, a reduction motor, a bearing two, a rotating shaft two, and sprockets; the mounting base one is installed on the upper end face of the movable seat, and the upper end face of the movable seat is provided with an elongated opening. The reduction motor is installed on the surface of the mounting base one. Three sets of openings are passed through the surface of the movable seat, and the bearing two is installed in the holes. The inner ring of the bearing two is connected to the rotating shaft two. Sprockets are installed on the output end of the reduction motor and on the surface of the rotating shaft two located inside the movable seat. Chains are sleeved on the surfaces of the multiple sets of sprockets. The clamping structure is installed on the rotating shaft two.

[0011] As a preferred technical solution, the clamping structure includes a threaded shaft and clamping plates; the surface of the rotating shaft is provided with an opening, the threaded shaft is inserted into the opening, and two sets of clamping plates are threadedly connected to the surface of the threaded shaft.

[0012] Furthermore, a rotating support structure is installed on both the left and right sides of the outer shell plate. The rotating support structure includes a rotating shaft three, a mounting seat two, and a bearing seat two. The mounting seat two is installed on the left and right sides of the outer shell plate and is symmetrically arranged along the transverse longitudinal section of the outer shell plate. The bearing seat two is installed on the outer side of the mounting seat two, and the rotating shaft three is connected to the inner ring of the bearing seat two. The rotating shaft three located on the right side of the outer shell plate is lower than the rotating shaft three on the other side.

[0013] As a preferred technical solution, the upper end face of the outer shell is provided with an opening that can be connected to a dust removal device, and an observation window is installed on the front side of the outer shell.

[0014] Compared with the prior art, the present invention provides an aluminum alloy grinding device, which has the following beneficial effects: This grinding device simultaneously clamps three sets of aluminum alloy tubes via a movable structure, and can rotate the three sets of aluminum alloy tubes synchronously, driving the aluminum alloy tubes to move towards the outer side of the outer shell plate. Secondly, when installing the aluminum alloy tubes, one end of the aluminum alloy tube is located in the middle of the grinding belt, so the movable structure can drive the aluminum alloy tube to the left to achieve grinding. Through this setting, the device can process three sets of aluminum alloy tubes at one time, greatly improving the grinding efficiency of aluminum alloy tubes.

[0015] To improve the polishing effect on aluminum alloy tubes, a support structure is used to support the polishing belt. (See [reference]). Figure 5 It is evident that this design provides the grinding belt with sufficient support, ensuring that when the aluminum alloy is pressed against the grinding belt, it not only does not hinder the grinding of adjacent aluminum alloy tubes but also effectively increases the contact area between the grinding belt and the aluminum alloy tubes.

[0016] To facilitate the movement of the aluminum alloy tube via the moving structure, mounting base two, bearing base two, and rotating shaft three are installed on the outer side of the outer shell plate. This effectively provides support for the aluminum alloy tube, preventing it from sagging due to its own weight. Furthermore, the height of rotating shaft three on the left side of the outer shell plate is lower than that on the right side. This is to prevent the aluminum alloy tube from colliding with rotating shaft three when the moving structure moves the aluminum alloy tube to the left. Moreover, as the aluminum alloy tube continues to move to the left, it will inevitably sag due to its weight. This lower height allows the moving structure to pull the aluminum alloy tube to the left while providing support for it in the subsequent movement. Attached Figure Description

Detailed Implementation

[0019] 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. Example

[0020] Please see Figure 1-7 This utility model provides the following technical solution: an aluminum alloy grinding device, including a worktable 1, a feeding structure on the upper surface of the worktable 1, and a housing plate 6 bolted to the upper surface of the worktable 1. A grinding structure capable of simultaneous grinding of multiple sets is also installed on the inner side of the housing plate 6. The grinding structure includes a drive structure and a grinding assembly, which includes a rotating shaft 9, a bearing seat 10, a pulley 11, and a grinding belt 12. Three sets of openings are triangularly formed on the left and right sides of the housing plate 6, and bearing seats 10 are installed at the openings on the left and right sides of the housing plate 6. The inner ring of the bearing seat 10 is connected to the rotating shaft 9, and the rotating shaft 9 is located inside the housing plate 6 on its surface. Each set is equipped with pulleys 11, and a grinding belt 12 is fitted on the surface of two adjacent sets of pulleys 11. At least three sets of aluminum alloy tubes 23 are clamped on the feeding structure, and one end face of each set of aluminum alloy tubes 23 is located in the middle of the surface of the corresponding grinding belt 12. The feeding structure consists of a moving structure, a rotating structure, and a clamping structure. The aluminum alloy tubes 23 are clamped by the clamping structure. The driving structure is connected to the surface of one set of rotating shafts 9 and is driven to rotate through the rotating structure. It is driven to move through the moving structure. The inner side of the outer shell plate 6 is also provided with a support structure to support the grinding belt 12. The surface of the aluminum alloy tube 23 contacts the surface of the grinding belt 12 and is pressed against the surface of the grinding belt 12 in the direction of the grinding belt 12.

[0021] In this implementation scheme, the specific working principle is as follows: First, the aluminum alloy tube 23 is installed into the clamping structure in the moving structure, so that one end of the aluminum alloy tube 23 is located in the middle of the grinding belt 12. At this time, the drive structure is activated to make the rotating shaft 9 rotate. Since multiple sets of rotating shafts 9 are connected to pulleys 11, the three sets of rotating shafts 9 start to run synchronously, which drives the grinding belt 12 to grind the surface of the aluminum alloy tube 23. At this time, the rotating structure in the moving structure runs, which drives the aluminum alloy tube 23 to start to rotate slowly through the clamping structure, and slowly moves to the left through the moving structure, thereby completing the grinding operation of the aluminum alloy tube 23. Through this structure, the device can grind three sets of aluminum alloy tubes 23 at one time, thereby greatly improving the grinding efficiency of the device. Through the continuous leftward movement of the moving structure, the aluminum alloy tube 23 is moved out of the outer shell plate 6, and then removed from the clamping state of the aluminum alloy tube 23 and the clamping structure.

[0022] Based on the above, in order to ensure that the grinding belt 12 can be properly pressed against the aluminum alloy tube 23 without affecting other structures, please refer to the following for details. Figure 5 and Figure 7As can be seen, the support structure includes a mounting plate 13, a connecting plate 14, an arc-shaped plate 15, a shaft 16, a bearing 17, and a pulley 18. Two sets of mounting plates 13 are mounted on the top surface of the inner side of the outer shell plate 6, and another set of mounting plates 13 is mounted on the bottom surface of the inner side of the outer shell plate 6. A connecting plate 14 is fixedly mounted on the surface of the mounting plate 13, and an arc-shaped plate 15 is bolted to the inner side of the connecting plate 14. An opening is formed on the surface of the arc-shaped plate 15, and a bearing 17 is installed in the opening. The inner ring of the bearing 17 is connected to the shaft 16, and a pulley 18 is mounted on the surface of the shaft 16 and contacts the grinding belt 12. Figure 5 The display shows a situation where the aluminum alloy tube 23 is not compressed. In actual operation, the aluminum alloy tube 23 is compressed with the grinding belt 12 at this location. The structure of the arc plate 15 provides sufficient compression space, which facilitates the compression operation between the aluminum alloy tube 23 and the grinding belt 12. This increases the contact area between the grinding belt 12 and the surface of the aluminum alloy tube 23, thereby improving the grinding effect of the grinding belt 12 and the aluminum alloy tube 23.

[0023] Secondly, for details on the driving structure, please refer to [link / reference]. Figure 3 and Figure 4 As can be seen, the drive structure includes a servo motor 26, pulleys 27, and a transmission belt 28. The servo motor 26 is mounted on the rear side of the outer casing plate 6, and pulleys 27 are mounted on the output end and the surface of the rotating shaft 9. The transmission belt 28 is sleeved on the surface of the two sets of pulleys 27. The servo motor 26 drives the pulleys 27 to rotate, thereby causing the rotating shaft 9 to rotate. Since the surfaces of the three sets of rotating shafts 9 are all sleeved on the pulleys 11 by the grinding belt 12, the three sets of rotating shafts 9 can run synchronously, thereby driving the grinding belt 12 to rotate, so as to perform grinding operations on the aluminum alloy tube 23.

[0024] For details on the moving structure, please refer to [link / reference]. Figure 3 and Figure 4 As can be seen, the moving structure includes a guide rail 2, a rack 3, a moving seat 4, and a stepper motor 5. The guide rail 2 and the rack 3 are both mounted on the upper surface of the worktable 1, and the moving seat 4 is movably mounted on the guide rail 2. The stepper motor 5 is mounted on the bottom inner side of the moving seat 4. The output end of the stepper motor 5 is connected to a gear and forms a meshing transmission with the rack 3. The rotating structure is mounted on the moving seat 4. The stepper motor 5 drives the meshing transmission between the gear and the rack 3, thereby driving the moving seat as a whole to move along the direction of the guide rail 2, and thus driving the rotating structure to move in conjunction with the clamping structure.

[0025] Based on the above, the details of the rotating structure can be found in [reference needed]. Figure 3-5As can be seen, the rotating structure includes a mounting base 7, a reduction motor 8, a bearing 19, a rotating shaft 20, and sprockets 29. The mounting base 7 is installed on the upper end face of the movable seat 4, and the upper end face of the movable seat 4 is provided with an elongated opening. The reduction motor 8 is installed on the surface of the mounting base 7. Three sets of openings are passed through the surface of the movable seat 4, and the bearing 19 is installed in the holes. The inner ring of the bearing 19 is connected to the rotating shaft 20. Sprockets 29 are installed on the output end of the reduction motor 8 and on the surface of the rotating shaft 20 located inside the movable seat 4. Chains are sleeved on the surfaces of the multiple sets of sprockets 29. The clamping structure is installed on the rotating shaft 20. The reduction motor 8 drives the sprockets 29 to rotate, and the multiple sets of sprockets 29 drive the rotating shaft 20 to rotate through the transmission action of the chain. In turn, the clamping structure drives the aluminum alloy tube 23 to rotate, so that the grinding belt 12 can grind and cover the entire surface of the aluminum alloy tube 23.

[0026] Based on the above, please refer to the details of the clamping structure. Figure 6 As can be seen, the clamping structure includes a threaded shaft 24 and a clamping plate 25. The surface of the rotating shaft 9 is provided with an opening, into which the threaded shaft 24 is inserted. Two sets of clamping plates 25 are threadedly connected to the surface of the threaded shaft 24. The aluminum alloy tube 23 is sleeved on the outside of the clamping plate 25. Then, the threaded shaft 24 is rotated, causing the two sets of clamping plates 25 to move in opposite directions, thereby clamping and fixing the aluminum alloy tube 23. It should be noted that due to the weight of the aluminum alloy tube 23, when it is located on the outside of the clamping plate 25, it is in contact with the upper clamping plate 25. Since the surface of the clamping plate 25 is curved, it can fit the aluminum alloy tube 23 well. Therefore, the clamping plate 25 itself is already stuck and will not affect the clamping effect. Furthermore, the rotation of the threaded shaft 24 will not cause the clamping plate 25 to rotate.

[0027] For details on providing support for the aluminum alloy tube 23, please refer to [link / reference needed]. Figure 1 and Figure 2 As can be seen, a rotating support structure is installed on both the left and right sides of the outer shell plate 6. The rotating support structure includes a rotating shaft 22, a mounting seat 30, and a bearing seat 31. The mounting seat 30 is installed on the left and right sides of the outer shell plate 6 and is symmetrically arranged along the transverse longitudinal section of the outer shell plate 6. The bearing seat 31 is installed on the outer side of the mounting seat 30. The inner ring of the bearing seat 31 is connected to the rotating shaft 22. The rotating shaft 22 on the right side of the outer shell plate 6 is lower than the rotating shaft 22 on the other side. The lower rotating shaft 22 is mainly for supporting the aluminum alloy tube 23 when it is being discharged, while the higher rotating shaft 22 provides some support for the aluminum alloy tube 23 when it is being polished.

[0028] For easier connection to dust removal equipment and to facilitate observation of the grinding process by staff, please refer to the following: Figure 1 and Figure 2As can be seen, the upper surface of the outer shell plate 6 is provided with an opening, which can be connected to the dust removal equipment. Secondly, an observation window 21 is installed on the front side of the outer shell plate 6.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
