Description

Technical Field

[0001] The present invention relates to the field of metal processing, and more specifically, to a surface treatment device for non-ferrous metal castings. Background Art

[0002] Non-ferrous metals, in the narrow sense, also known as non-ferrous metals, are collectively referred to as all metals other than iron, manganese, and chromium. In the broad sense, non-ferrous metals also include non-ferrous alloys. A non-ferrous alloy is an alloy composed of a non-ferrous metal as the matrix (usually more than 50%) and one or several other elements added. Modern non-ferrous metals and their alloys have become indispensable structural materials and functional materials in the fields of machinery manufacturing, construction, electronics industry, aerospace, nuclear energy utilization, etc.

[0003] In the existing equipment, the grinding disc is controlled in height by a hydraulic rod. When the grinding disc is grinding, its height remains fixed. For some deep burrs on the surface, it is impossible to grind well, resulting in too shallow grinding and incomplete grinding. Moreover, the feed rates required for grinding different non-ferrous metals are inconsistent. If the feed rate of the grinding disc is controlled by a hydraulic rod, due to the large thrust of the hydraulic rod, the instantaneous contact force between the grinding disc and the metal surface is too large, easily causing the grinding to be too deep and damaging the casting, and it is impossible to accurately control the feed rate of grinding. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a surface treatment device for non-ferrous metal castings.

[0011] Further, the grinding and polishing component includes a mounting plate fixed on the outer surface of the discharge pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In this solution, by setting the control component, as the grinding progresses, the first spring pushes the moving plate and the entire grinding and polishing assembly to move downward. When the moving plate contacts the nut, the moving plate cannot continue to move downward, and the grinding and polishing assembly cannot move downward either, indicating that the required grinding feed amount has been completed. Thus, it is possible to avoid the continuous grinding and polishing of non-ferrous metals by the grinding and polishing assembly, prevent the over-grinding and polishing of non-ferrous metals, resulting in material waste, as well as the problems of increasing unnecessary processing time and resource consumption.

[0019] 2.

The polishing paste can be added intermittently during grinding and polishing, which not only avoids the trouble of stopping the machine to add the polishing paste, but also ensures the safety of workers and effectively improves the work efficiency.

[0020] 3. This solution sets up a grinding and polishing assembly, rotates the first annular rack to drive the four first gears to rotate synchronously, and the first gears simultaneously drive the connecting bolts to rotate, so that the internal threaded sleeve gradually moves down on the outside of the connecting bolts and moves out from the inside of the slot, thereby completing the replacement of the grinding disc.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figures 1 to 12, A surface treatment device for non-ferrous metal castings, including a bottom plate 1. On both sides of the upper surface of the bottom plate 1, there are fixedly connected support frames 2. On the upper surface of the support frames 2, there is fixedly connected an electric push rod 3. The output end of the electric push rod 3 penetrates through the support frame 2 and is fixedly connected to an electric slide rail 4. Inside the electric slide rail 4, there is a slidably arranged electric slider 7 that matches it. The lower surface of the electric slider 7 is slidably connected to a control component 5 for grinding and treating the metal surface. In the middle of the upper surface of the bottom plate 1, there is fixedly connected a flipping component 6.

[0045] As Figure 2 and Figure 3 As shown, the control component 5 includes a motor frame 51 fixed to the lower surface of the electric slider 7. At the inner top of the motor frame 51, there is fixedly connected a first driving motor 52. The output end of the first driving motor 52 is fixedly connected to a spline shaft 59. In the middle of the lower surface of the motor frame 51, there is fixedly connected an external threaded rod 53. An outer threaded rod 53 is slidably sleeved with a moving plate 58. The outer surface of the external threaded rod 53 is sleeved with a first spring 54. The outer surface of the external threaded rod 53 is threadedly connected to a nut 55. At the front end of one side of the lower surface of the motor frame 51, there is fixedly connected a scale 511. In the middle of the moving plate 58, there is rotatably connected a driving sleeve 510.

[0046] The bottom of the scale 511 penetrates through the inside of the moving plate 58. The scale 511 and the moving plate 58 slide relative to each other. The first spring 54 is located between the motor frame 51 and the moving plate 58. The top and bottom of the first spring 54 are respectively fixedly connected to the motor frame 51 and the moving plate 58. The bottom of the spline shaft 59 extends out of the driving sleeve 510. An adding component 56 is arranged on the outer surface of the driving sleeve 510. A grinding and polishing component 57 is arranged on the adding component 56.

[0047] When grinding non-ferrous metals, it is necessary to adjust the grinding feed rate according to different non-ferrous metals and the burrs on their surfaces. Therefore, before grinding, by rotating the nut 55, under the action of the thread, the nut 55 moves upward on the outer side of the outer threaded rod 53, driving the moving plate 58 to move upward on the outer surface of the outer threaded rod 53 and compress the first spring 54. When the first spring 54 is compressed to the limit and the moving plate 58 cannot move, at this time, the upper surface of the moving plate 58 is aligned with the "0" scale on the scale 511. When a certain amount of grinding is required, rotate the nut 55 in the reverse direction, so that the moving plate 58 moves downward on the outer side of the outer threaded rod 53. When the upper surface of the moving plate 58 reaches the corresponding value, stop rotating the nut 55. At this time, the electric push rod 3 drives the grinding and polishing assembly 57 as a whole to contact the metal surface and continue to press down, so that the driving sleeve 510 drives the moving plate 58 to continue to move upward on the outer side of the outer threaded rod 53 until the moving plate 58 cannot move. At this time, turn on the first driving motor 52. Through the cooperation of the spline shaft 59 and the driving sleeve 510, the grinding and polishing assembly 57 can be driven to rotate to grind the non-ferrous metal. As the grinding progresses, the first spring 54 pushes the moving plate 58 and the grinding and polishing assembly 57 as a whole to move downward. When the moving plate 58 contacts the nut 55, the moving plate 58 cannot continue to move downward, and the grinding and polishing assembly 57 cannot move downward either, indicating that the required grinding feed rate has been completed. Thus, it is possible to avoid the grinding and polishing assembly 57 continuing to move downward to continue grinding and polishing the non-ferrous metal, preventing over-grinding and polishing of the non-ferrous metal, resulting in material waste, as well as increasing unnecessary processing time and resource consumption.

[0048] As Figure 3 and Figure 4 shown, the adding component 56 includes two connecting plates 5610 fixed on the outer surface of the driving sleeve 510 and two triangular blocks 568 fixed on the lower surface of the moving plate 58. The lower surface of the connecting plate 5610 is fixedly connected with a storage cylinder 561. The bottom of the storage cylinder 561 is fixedly connected with a discharge pipe 569. The outer surface of the storage cylinder 561 is symmetrically provided with a second one-way valve 564 and a first one-way valve 562. A piston 563 is slidably connected inside the storage cylinder 561. The upper surface of the piston 563 is fixedly connected with two driving rods 565. Second springs 567 are symmetrically and fixedly connected to the outer surface of the storage cylinder 561 near the top. One side of the two driving rods 565 away from each other is fixedly connected with a fixing plate 566.

[0049] The top of the second spring 567 is fixedly connected with the lower surface of the fixing plate 566. A material injection port for adding materials is provided inside the piston 563, and a sealing plug is provided on the material injection port. The flow directions of the second one-way valve 564 and the first one-way valve 562 are from the outside to the inside of the storage cylinder 561. The grinding and polishing assembly 57 is arranged on the outer surface of the discharge pipe 569.

[0050] When the grinding and polishing assembly 57 is grinding, it is often necessary to add polishing paste to assist in polishing, which can not only effectively improve the polishing efficiency, but also improve the quality of non-ferrous metal polishing. However, when adding polishing paste during the operation of the equipment, the machine needs to be stopped, which not only wastes time, but also may accidentally touch the switch and cause the equipment to start unexpectedly, increasing the risk for workers.

[0051] Therefore, during grinding and polishing, a storage cylinder 561 is provided. The required polishing paste is added inside the storage cylinder 561. When the spline shaft 59 drives the drive sleeve 510 to rotate at a high speed, the drive sleeve 510 will simultaneously drive the storage cylinder 561 to rotate synchronously. The storage cylinder 561 will drive two drive rods 565 to rotate at the same time. The top of the drive rod 565 will contact the hypotenuse of the triangular block 568. When the drive rod 565 contacts the hypotenuse of the triangular block 568, the drive rod 565 will move downward, driving the piston 563 to move downward inside the storage cylinder 561, and squeezing the polishing paste inside the storage cylinder 561 into the inside of the discharge pipe 569, and adding it to the grinding area through the discharge pipe 569. When the drive rod 565 passes through the triangular block 568, the two second springs 567 reset and drive the drive rod 565 and the piston 563 to move upward. At this time, the gas will enter the inside of the storage cylinder 561 through the second one-way valve 564 and the first one-way valve 562. During grinding and polishing, the polishing paste can be added intermittently, which can not only avoid the trouble of stopping the machine to add polishing paste, but also ensure the safety of workers and effectively improve the work efficiency.

[0052] As Figure 5 - Figure 7 As shown in the figure, the grinding and polishing assembly 57 includes a mounting plate 571 fixed on the outer surface of the discharge pipe 569. The upper surface of the mounting plate 571 is rotatably connected with a first annular rack 574. Four connecting bolts 572 are evenly rotatably connected inside the mounting plate 571. The tops of the four connecting bolts 572 are fixedly connected with a first gear 573. Four slots 577 are evenly opened on the lower surface of the mounting plate 571. The outer surface of the connecting bolt 572 is threadedly connected with an internal thread sleeve 576. The lower surface of the internal thread sleeve 576 is fixedly connected with a grinding disc 575.

[0053] The lower part of the connecting bolt 572 extends into the inside of the slot 577. The internal thread sleeve 576 is located inside the slot 577. The first gear 573 and the first annular rack 574 are meshed with each other. The discharge pipe 569 penetrates through the inside of the grinding disc 575.

[0054] During the long-term grinding and polishing of the grinding disc 575, its surface will be ground smooth, resulting in low grinding efficiency and poor grinding quality. At this time, it needs to be replaced. However, the traditional grinding disc 575 is fixed to the equipment by bolts, and it takes a lot of time to disassemble multiple groups of bolts, and it is also easy to have the situation of thread slipping.

[0055] When it is necessary to replace the grinding disc 575, the first annular rack 574 is rotated at this time to drive the four first gears 573 to rotate synchronously. The first gear 573 drives the connecting bolt 572 to rotate at the same time, so that the internal thread sleeve 576 gradually moves downward outside the connecting bolt 572 and moves out of the inside of the slot 577, thus completing the replacement of the grinding disc 575. Align the internal thread sleeve 576 on the new grinding disc 575 and insert it into the inside of the slot 577, and then reverse the first annular rack 574 to drive the connecting bolt 572 to reverse through transmission, and gradually insert the internal thread sleeve 576 into the inside of the slot 577 to complete the installation.

[0056] As Figure 8 and Figure 9 shown, the flipping assembly 6 includes a cleaning pool 61 fixed on the upper surface of the bottom plate 1. One side of the cleaning pool 61 is fixedly connected with a third driving motor 610. The output end of the third driving motor 610 is fixedly connected with a transmission rod 62. Cross plates 63 are symmetrically and fixedly connected to the outer surface of the transmission rod 62. A cleaning assembly 64 is arranged at the inner bottom of the cleaning pool 61. Four corners on one side of one cross plate 63 are fixedly connected with hydraulic push rods 65. A support shaft 611 is fixedly connected to one side of the other cross plate 63. A pressing disc 66 is rotatably connected to the sides of the support shaft 611 and the hydraulic push rod 65 close to each other. A second annular rack 67 is fixedly connected to one side of the pressing disc 66 on the support shaft 611. Second driving motors 69 are fixedly connected to the four corners on one side of the cross plate 63. The output ends of the second driving motors 69 are fixedly connected with fourth gears 68.

[0057] The fourth gear 68 and the second annular rack 67 are meshed with each other, and a rubber pad is arranged on one side of the pressing disc 66.

[0058] After grinding and polishing are completed, there will be a certain amount of polishing paste on the upper surface of the non-ferrous metal. If it is not cleaned in time, it will cause unnecessary trouble in the subsequent processing of non-ferrous metal. At this time, turn on the third driving motor 610 to drive the transmission rod 62 to rotate. The transmission rod 62 drives the two cross plates 63 to rotate at the same time, and rotates the metal fixed between the two pressing discs 66 into the inside of the cleaning pool 61 for cleaning. While the non-ferrous metal is being cleaned, the non-ferrous metal above is simultaneously ground and polished, achieving twice the result with half the effort and greatly improving the work efficiency. Moreover, the non-ferrous metals on both sides can be loaded and unloaded. The second driving motor 69 drives the fourth gear 68 to rotate, and through the transmission of the second annular rack 67, drives the pressing disc 66 to rotate, so as to drive the metal between the pressing discs 66 to turn over, and comprehensive grinding and polishing and subsequent cleaning can be carried out.

[0059] As Figure 10 - Figure 12As shown in the figure, the cleaning component 64 includes a disk 641 rotatably disposed at the bottom inside the cleaning tank 61, a third gear 649 rotatably disposed at one side edge of the cross plate 63, a worm 645 rotatably disposed at one side bottom inside the cleaning tank 61, and a rectangular frame 644 slidably disposed on the front and rear sides of the inner surface of the cleaning tank 61. A second gear 646 is fixedly connected to the outer surface of the worm 645. A driving block 643 is fixedly connected to the edge of the upper surface of the disk 641. A worm gear 648 is fixedly connected to the bottom of the disk 641. Connecting rods 647 are fixedly connected to both sides of the rectangular frame 644. A buffer member is fixedly connected to one side of the connecting rod 647. A cleaning brush 642 is disposed on the buffer member.

[0060] The buffer member includes a rectangular groove 6410 fixedly connected to one side of the connecting rod 647. Two third springs 6412 are fixedly connected to the inside of the rectangular groove 6410. A telescopic block 6411 is fixedly connected to the top of the third spring 6412. A cleaning brush 642 is fixedly connected to the top of the telescopic block 6411.

[0061] During cleaning, manual cleaning is required, which not only has low cleaning efficiency but also increases the labor intensity of the staff. Therefore, when non-ferrous metals enter the inside of the cleaning tank 61, the corresponding third gear 649 comes into contact and meshes with the second gear 646. At this time, the corresponding second drive motor 69 is started. The second drive motor 69 drives the second annular rack 67 and the third gear 649 to rotate through transmission. The second annular rack 67 drives the metal to rotate inside the cleaning tank 61 through the pressing disk 66. The third gear 649 drives the worm 645 to rotate through the second gear 646. The worm 645 drives the disk 641 to rotate through the worm gear 648. The disk 641 drives the driving block 643 to move circumferentially, driving the rectangular frame 644 to swing left and right. The rectangular frame 644 drives the cleaning brush 642 to wipe back and forth on the surface of the metal through the connecting rod 647. At the same time, the metal rotates inside the cleaning tank 61, enabling the cleaning brush 642 to wipe the metal comprehensively. When the metal rotates, it continuously presses the cleaning brush 642. The cleaning brush 642 cooperates with the telescopic block 6411 and the third spring 6412 to continuously contract and reset, avoiding hindering the rotation of the metal.

[0062] Usage method: First, through the mutual cooperation of the various parts of the control component 5, the feed amount of grinding and polishing can be accurately controlled to avoid excessive grinding. At the same time, during grinding, the piston 563 continuously moves up and down inside the storage cylinder 561, intermittently adding the polishing paste inside the storage cylinder 561 to the grinding area. Rotating the first annular rack 574 drives the four connecting bolts 572 to rotate through transmission, quickly disassembling the grinding disk 575.

[0063] Then, the second annular rack 67 drives the pressing disk 66 to rotate, synchronously driving the metal to rotate, enabling rapid turning of the metal. The operations of grinding and cleaning can be carried out synchronously within the same time. Through the cooperation of the components of the cleaning assembly 64, the cleaning brush 642 continuously moves left and right to wipe the metal surface. The self-rotation of the metal can achieve comprehensive cleaning and improve efficiency.

[0064] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent replacements or changes, should be covered by the protection scope of the present invention.
