Description

Technical Field

[0001] The present application relates to the field of grinding equipment, and in particular to a forging external grinding device. Background Art

[0002] Forging grinding equipment is a machine used to process the surface of metal forgings. It removes burrs, oxides and other unevenness on the surface of forgings by grinding, polishing or brushing, thereby improving the quality and finish of forgings. Forging grinding machines are generally composed of motors, grinding heads, control systems, protective covers, etc. The motor provides power to make the grinding head produce rotational motion. The grinding head can be a grinding head, grinding wheel, etc. of various shapes and specifications to adapt to the grinding of different shapes of forging surfaces. The protective cover is set outside the grinding head to prevent the operator from contacting the rotating grinding head and ensure safe operation.

[0003] The grinding process of forgings generally includes two parts: rough grinding and fine grinding. Rough grinding is first used to remove burrs, protrusions, oxide layers and other defects on the surface of the forgings to make the surface of the forgings smooth. Fine grinding is then used to enable the steel to maintain the most precise geometric shape and fine crack depth, achieve higher precision requirements, and prepare for the subsequent polishing process.

[0004] In response to the above-mentioned related technologies, the inventors found that the grinding heads corresponding to coarse grinding and fine grinding have different finenesses. Therefore, different grinding heads need to be replaced according to the grinding requirements, but the process of replacing the grinding heads is relatively cumbersome. First, the fasteners that fix the protective cover need to be unscrewed, the protective cover needs to be removed from the frame, and then the grinding head needs to be removed from the rotating shaft. Next, the new grinding head needs to be installed on the rotating shaft, and then the protective cover needs to be installed on the frame again, and the fasteners of the protective cover need to be tightened to complete the replacement of the grinding head. The whole process takes a long time and is quite cumbersome. In addition, some grinding heads are relatively large in size and heavy in weight, and are more difficult to carry. Therefore, for workers, replacing the grinding head is time-consuming and labor-intensive, which affects work efficiency. Summary of the invention

[0050] The switching mechanism 5 can be used to switch the transmission wheel 42 and the rough grinding pulley 45 or the fine grinding pulley 46 connected by the first belt 47. When the transmission wheel 42 is connected to the rough grinding pulley 45 by the first belt 47, the rough grinding mechanism 6 is driven to operate and the forging is rough ground; when the transmission wheel 42 is connected to the fine grinding pulley 46 by the first belt 47, the fine grinding mechanism 7 is driven to operate and the forging is fine ground.

[0051] Reference Figure 3 The switching mechanism 5 includes a lifting assembly 51, a tensioning assembly 52 and a switching assembly 53. The lifting assembly 51 is used to drive the fine grinding mechanism 7 to slide up and down. When the rough grinding mechanism 6 is working, the lifting assembly 51 drives the fine grinding mechanism 7 to rise, which is convenient for the rough grinding mechanism 6 to work. When the fine grinding mechanism 7 needs to work, the lifting assembly 51 drives the fine grinding mechanism 7 to descend and contact with the forging, thereby fine grinding the forging. In this process, the fine grinding pulley 46 rises and falls, and the tension of the first belt 47 is adjusted by the tensioning assembly 52 to adapt to the fine grinding pulley 46.

[0052] Reference Figure 4 The lifting assembly 51 includes a first slider 511, a second slider 512, a push rod 513 and a lifting screw 514. The lifting screw 514 is rotatably connected to the top of the support seat 3 and extends into the support seat 3. The lifting screw 514 is axially vertically arranged.

[0053] Reference Figure 4A driving spring 516 is fixedly connected between the top surface of the second slider 512 and the top wall of the second slide groove 32. When it is necessary to raise the fine grinding mechanism 7, the lifting screw 514 is rotated, and the lifting screw 514 drives the first slider 511 to slide downward. Due to the action of the guide inclined surface 517, the first slider 511 pushes the push rod 513 to slide in the direction close to the second slider 512, and pushes the second slider 512 to slide upward, thereby driving the second rotating shaft 44 to slide upward, and the second rotating shaft 44 drives the fine grinding mechanism 7 to slide upward. At this time, the driving spring 516 is in a compressed state; when it is necessary to lower the fine grinding mechanism 7, the lifting screw 514 is rotated, and the lifting screw 514 drives the first slider 511 to slide downward. Due to the action of the guide inclined surface 517, the first slider 511 pushes the push rod 513 to slide in the direction close to the second slider 512, and pushes the second slider 512 to slide upward. When the fine grinding mechanism 7 is turned, the lifting screw 514 is rotated in the opposite direction, and the lifting screw 514 drives the first slider 511 to slide upward. At this time, the first slider 511 is no longer pressed against the push rod 513, and the driving spring 516 drives the second slider 512 to slide downward. Due to the action of the guide inclined surface 517, the second slider 512 drives the push rod 513 to slide in the direction close to the first slider 511. When the push rod 513 and the first slider 511 are pressed against each other, the second slider 512 stops sliding, thereby driving the second rotating shaft 44 to slide downward, and the second rotating shaft 44 drives the fine grinding mechanism 7 to slide downward. In order to facilitate the rotation of the lifting screw 514, a hand wheel 515 is fixedly connected to the top of the lifting screw 514.

The rough grinding wheel 61 is arranged on the first rotating shaft 43, and is used to perform overall rough grinding on the surface of the forging. The rough grinding head driving assembly 63 is driven by the first rotating shaft 43. The rough grinding head driving assembly 63 drives the rough grinding head 62 to perform detailed rough grinding on the grooves on the surface of the forging that are not easy to grind, so that the grinding is more complete, and it is also more convenient to grind the surface of the forging, and the scope of application of grinding is wider. The rough grinding wheel 61, the rough grinding head 62 and the rough grinding head driving assembly 63 are all located in the protective cover 65, and the protective cover 65 plays a protective role to prevent workers from accidentally touching the rough grinding wheel 61 or the rough grinding head 62, and ensure the safety of the grinding process.

The protective cover 65 is fixedly connected to the side of the support seat 3 facing the rough grinding wheel 61 and the rough grinding wheel 61 is located in the protective cover 65.

[0060] Reference Figure 7The rough grinding head driving assembly 63 includes a fixed shaft 631, a first bevel gear set 632, and a second bevel gear set 633. The fixed shaft 631 is rotatably connected to the support seat 3 and the axial direction of the fixed shaft 631 is parallel to the axial direction of the first rotating shaft 43. The first rotating shaft 43 and the fixed shaft 631 are coaxially fixedly connected with a second pulley 634. The two second pulleys 634 are connected by a second belt 635.

One end of the fixed shaft 631 extends into the first gear box 636 and is coaxially fixedly connected to one of the bevel gears of the first bevel gear set 632. A telescopic rod 638 is coaxially fixedly connected to the other bevel gear of the first bevel gear set 632. The telescopic rod 638 passes through the first gear box 636 and is located below the first gear box 636. The telescopic rod 638 is axially vertically arranged. A second gearbox 637 is disposed below the first gearbox 636. A fine-tuning cylinder 639 is fixedly connected between the first gearbox 636 and the second gearbox 637.

The connecting shaft 640 is axially parallel to the fixed shaft 631 and extends out of the second gearbox 637. The rough grinding head 62 is coaxially fixedly connected to the connecting shaft 640.

[0061] Reference Figure 7 and Figure 8 The telescopic rod 638 includes a first telescopic rod 6381 and a second telescopic rod 6382. The first telescopic rod 6381 is rotatably connected to the bottom of the first gear box 636, and the second telescopic rod 6382 is rotatably connected to the top of the second gear box 637.

When the first bevel gear set 632 drives the first telescopic rod 6381 to rotate, due to the connection of the clamping block 6384, the first telescopic rod 6381 drives the second telescopic rod 6382 to rotate, and the second telescopic rod 6382 drives the second bevel gear set 633 to rotate.

[0062] When the rough grinding wheel 61 is grinding the forging surface as a whole, the fine adjustment cylinder 639 contracts to drive the rough grinding head 62 to rise. At this time, the height of the bottom surface of the rough grinding head 62 is higher than the height of the bottom surface of the rough grinding wheel 61, so that the rough grinding wheel 61 can grind. When there are some grooves on the forging surface that are not easy to grind, the fine adjustment cylinder 639 drives the rough grinding head 62 to descend, the first rotating shaft 43 drives the fixed shaft 631 to rotate through the second belt 635, the fixed shaft 631 drives the telescopic rod 638 to rotate through the first bevel gear set 632, the telescopic rod 638 drives the second bevel gear set 633 to rotate, and then drives the rough grinding head 62 to rotate through the connecting shaft 640, so as to grind the parts that are not easy to grind by the rough grinding wheel 61, so that the grinding of the forging surface is more sufficient, and at the same time, there is no need to replace the rough grinding wheel 61, and fine grinding can be completed, which is convenient and fast, and improves work efficiency.

[0063] Reference Figure 6 and Fig. 9 The fine grinding mechanism 7 includes a fine grinding wheel 71, a fine grinding head 72, a fine grinding head driving assembly 73 and a protective cover 65. The fine grinding wheel 71 is arranged on the second rotating shaft 44. The installation method of the fine grinding wheel 71 and the fine grinding head 72, and the structure of the fine grinding head driving assembly 73 are consistent with those of the rough grinding mechanism 6, and will not be described in detail here. The only difference between the two is that the protective cover 65 of the fine grinding mechanism 7 is fixedly connected to the second slider 512, and the fixed shaft 631 of the fine grinding head driving assembly 73 is rotatably connected to the inner wall of the protective cover 65 of the fine grinding mechanism 7. The second slider 512 slides up and down to drive the protective cover 65 to move up and down, thereby driving the fine grinding mechanism 7 to move up and down as a whole.

[0064] Similarly, when the fine grinding wheel 71 is grinding the entire surface of the forging, the fine adjustment cylinder 639 contracts to drive the fine grinding head 72 to rise, and the height of the bottom surface of the fine grinding head 72 is higher than the height of the bottom surface of the fine grinding wheel 71, so that the fine grinding wheel 71 can grind. When there are some grooves on the surface of the forging that are not easy to grind, the fine adjustment cylinder 639 drives the fine grinding head 72 to descend, and then drives the fine grinding head 72 to rotate through the fine grinding head driving assembly 73, so as to grind the parts that are not easy to grind with the fine grinding wheel 71.

[0065] Reference Figure 1 and Fig.10In order to facilitate the inspection and maintenance of the rough grinding mechanism 6 and the fine grinding mechanism 7, an inspection port 651 is provided at one end of the protective cover 65 away from the support seat 3, and a cover plate 652 is hinged on the inspection port 651 to facilitate opening the inspection port 651. A hanging rod 653 is rotatably connected to the cover plate 652, and a locking block 654 is fixedly connected to the protective cover 65. A groove is provided on the locking block 654 to accommodate the hanging rod 653. When the cover plate 652 is located in the inspection port 651, the hanging rod 653 is rotated into the locking block 654, thereby locking the cover plate 652; when it needs to be opened, the hanging rod 653 is rotated to disengage from the locking block 654, thereby opening the cover plate 652, which is convenient and quick.

[0066] The implementation principle of a forging external grinding device in an embodiment of the present application is: when the forging surface needs to be ground, the forging is first fixed on the workbench 1, the first drive motor 213, the second drive motor 223 and the third drive motor 233 are adjusted, and the positions of the rough grinding mechanism 6 and the fine grinding mechanism 7 are adjusted along the X-axis, Y-axis and Z-axis directions. When the rough grinding wheel 61 is aligned with the forging, the position adjustment is completed.

[0067] The grinding drive motor 41 is started, and the grinding drive motor 41 drives the rough grinding wheel 61 to rotate through the first belt 47, and the rough grinding wheel 61 performs rough grinding on the forging surface as a whole. At this time, the height of the rough grinding head 62, the fine grinding wheel 71 and the bottom surface of the fine grinding head 72 are all higher than the rough grinding wheel 61, so that the rough grinding wheel 61 can perform grinding. When there are some grooves on the forging surface that are not easy to grind, the fine adjustment cylinder 639 drives the rough grinding head 62 to descend, the first rotating shaft 43 drives the fixed shaft 631 to rotate through the second belt 635, the fixed shaft 631 drives the telescopic rod 638 to rotate through the first bevel gear set 632, the telescopic rod 638 drives the second bevel gear set 633 to rotate, and then drives the rough grinding head 62 to rotate through the connecting shaft 640, so as to grind the parts that are not easy to grind by the rough grinding wheel 61, so that the grinding of the forging surface is more sufficient, and at the same time, there is no need to replace the rough grinding wheel 61, and fine grinding can be completed, which is convenient and fast, and improves work efficiency.

[0068] After the rough grinding is completed, the fine grinding mechanism 7 is switched to perform fine grinding on the forging. When switching, the fine adjustment screw 536 is rotated to drive the clamping frame 531 to move toward the fine grinding pulley 46, and the clamping frame 531 drives the first belt 47 to move from the second rotating wheel 539 to the fine grinding pulley 46, and at the same time, the first belt 47 is also moved from the rough grinding pulley 45 to the first rotating wheel 538, thereby completing the adjustment of the position of the first belt 47, and switching from driving the rough grinding pulley 45 to driving the fine grinding pulley 46. The second slider 512 is pushed downward by the driving spring 516. Due to the action of the guide inclined surface 517, the second slider 512 pushes the push rod 513 to slide in the direction close to the first slider 511. When the push rod 513 and the first slider 511 are pressed against each other, the second slider stops sliding, thereby driving the second rotating shaft 44 to slide downward. The second rotating shaft 44 drives the fine grinding mechanism 7 to slide downward. When the height of the bottom surface of the fine grinding wheel 71 is lower than the rough grinding wheel 61, the hand wheel 515 is stopped. At this time, the position of the sliding seat 522 is adjusted to tighten the first belt 47. Then the rotating handle 527 is rotated to lock the sliding seat 522, and the switching and tensioning of the first belt 47 are completed.

[0069] Start the grinding drive motor 41 again, and the grinding drive motor 41 drives the fine grinding wheel 71 to rotate through the first belt 47. The fine grinding wheel 71 performs overall fine grinding on the surface of the forging. When encountering some grooves and other places on the surface of the forging that are difficult to grind, the fine-tuning cylinder 639 drives the fine grinding head 72 to descend, and then drives the fine grinding head 72 to rotate through the fine grinding head driving assembly 73, so as to grind the parts that are difficult to grind with the fine grinding wheel 71.

[0070] Through this device, the integrated rough grinding and fine grinding of the outer part of the forging can be completed, and the grinding wheel does not need to be replaced in the middle. The switching of the driving of the rough grinding wheel 61 and the fine grinding wheel 71 can be completed through the cooperation of the same grinding drive motor 41 and the switching mechanism 5. The operation is simple and convenient, which greatly reduces the workload of workers and improves the grinding efficiency. At the same time, for the parts of the forging surface that are not easy to grind with the grinding wheel, the rough grinding head 62 and the fine grinding head 72 can be used in combination for grinding. The rough grinding head 62 and the fine grinding head 72 are also driven by the grinding drive motor 41. On the one hand, energy is saved, and on the other hand, the surface of the forging is more convenient to grind, and the scope of application is wider. At the same time, the problem of replacing the grinding head is avoided, and the grinding efficiency is higher.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
