Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of CNC machine tool technology, and more specifically, to a multi-functional CNC machine tool for machining engine crankshafts. Background Technology
[0002] The engine crankshaft is the core component of an internal combustion engine, responsible for converting the reciprocating motion of the piston into rotational motion, thereby outputting power. It is usually forged or cast from high-strength alloy steel. The crankshaft needs to undergo precision machining and heat treatment to ensure wear resistance, fatigue resistance and dynamic balance performance. Its design directly affects the smoothness, efficiency and life of the engine. It is widely used in automobiles, ships and industrial machinery and is a key hub for power transmission.
[0003] During the machining of engine crankshafts, operators frequently use corresponding CNC machine tools. While existing CNC machine tools possess basic machining functions, a significant amount of machining debris tends to accumulate on the top of the worktable after each machining operation. This debris buildup not only affects subsequent machining operations but also poses a risk of burns or cuts from sharp edges when operators attempt to clean it, given that the debris is typically hot.

Finally, the two sealing plates will drive the two limiting blocks to move horizontally towards each other under the limiting action of the machine housing. When the two sealing plates are in contact, the front of the machine housing will be sealed, preventing debris from splashing from the front of the machine housing during subsequent processing.

[0031] like Figures 1-5 As shown, a multi-functional CNC machine tool for machining engine crankshafts according to an embodiment of the present disclosure is illustrated. It includes a housing 1, a platform 2 movably connected to the bottom of the inner cavity of the housing 1, a support base 3 fixedly connected to the right side of the platform 2, a power motor 4 movably connected inside the support base 3, a rotating shaft 5 fixedly sleeved at the other end of the output shaft of the power motor 4, a rotating rod 6 fixedly sleeved at the other end of the rotating shaft 5, a hollow rod 7 movably connected to the outer surface of the rotating rod 6, a connecting rod 8 fixedly connected to the left side of the hollow rod 7, the other end of the connecting rod 8 penetrating the platform 2 and extending into the interior of the platform 2 and fixedly connected to a push plate 9, the bottom of the push plate 9 movably connected to the top of the platform 2, baffles 10 fixedly connected to both the left and right sides of the top of the platform 2, the outer surface of the push plate 9 movably connected to the inner side of a collection box 11, and a collection box 11 movably connected to the interior of the platform 2.
[0032] When the power motor 4 starts running, it will cause the rotating shaft 5 to drive the rotating rod 6 to rotate, and the rotating rod 6 will squeeze and push the hollow rod 7. At this time, the hollow rod 7 will drive the connecting rod 8 to move horizontally to the left under the limiting action of the platform 2. Finally, the push plate 9 will push the processing debris along the top of the platform 2 into the inside of the collection box 11 for centralized collection.
[0033] In some examples, a fixing plate 12 is fixedly connected to both the left and right sides of the bottom of the inner cavity of the housing 1. A drive motor 13 is fixedly connected to the left side of the fixing plate 12. A first threaded rod 15 is fixedly sleeved at the other end of the output shaft of the drive motor 13. The other end of the first threaded rod 15 passes through the fixing plate 12 and the shelf 2 and extends into the interior of the fixing plate 12 and is threadedly sleeved with the interior of the shelf 2. A protective shell 14 is fixedly installed on the outer surface of the drive motor 13.
[0034] When the drive motor 13 starts running, it will cause the first threaded rod 15 to rotate, at which time the platform 2 will move left and right.
[0035] In some examples, a first limiting rod 16 is fixedly connected between drive motors 13, and the outer surface of the first limiting rod 16 is movably connected to the inside of the shelf 2.
[0036] Due to the limiting effect of the first limiting rod 16, the shelf 2 can only move horizontally left and right.
[0037] In some examples, vertical plates 17 are fixedly connected to the front and rear sides of the top of the housing 1. A first motor 18 is fixedly connected to the back of the vertical plate 17. A second threaded rod 19 is fixedly sleeved at the other end of the output shaft of the first motor 18. The other end of the second threaded rod 19 passes through the vertical plate 17 and extends into the interior of the vertical plate 17 and is threadedly sleeved with a sliding block 20.
[0038] When the first motor 18 starts running, it will cause the second threaded rod 19 to rotate, at which time the sliding block 20 will move back and forth.
[0039] In some examples, the outer surface of the sliding block 20 is movably connected to the interior of the top of the housing 1, and a pneumatic cylinder 21 is fixedly connected to the top of the sliding block 20. The bottom end of the pneumatic cylinder 21 passes through the sliding block 20 and extends into the interior of the sliding block 20 and is fixedly connected to the machining tool body 22.
[0040] When the pneumatic cylinder 21 starts running, it will cause the machining tool body 22 to move vertically downward.
[0041] In some examples, a rectangular plate 23 is fixedly connected to the front of the vertical plate 17, a second motor 24 is fixedly connected to the top of the rectangular plate 23, and a rotating rod 25 is fixedly sleeved at the other end of the output shaft of the second motor 24.
[0042] When the second motor 24 starts running, it will cause the swivel rod 25 to rotate.
[0043] In some examples, the other end of the swivel 25 passes through the rectangular plate 23 and extends to the outside of the rectangular plate 23 and is fixedly sleeved with a gear 26. The top and bottom of the outer surface of the gear 26 are respectively meshed with a first toothed plate 27 and a second toothed plate 28.
[0044] When the rotating rod 25 rotates, it will cause the gear 26 to start rotating, and cause the first toothed plate 27 and the second toothed plate 28 to move in opposite directions.
[0045] In some examples, the top of the housing 1 is fixedly connected with a second limiting rod 31. There are two second limiting rods 31, and the outer surfaces of the two second limiting rods 31 are respectively movably sleeved with the inside of the first toothed plate 27 and the second toothed plate 28.
[0046] Due to the design of the second limiting rod 31, the first toothed plate 27 and the second toothed plate 28 can only move horizontally left and right.
[0047] In some examples, the bottom of the first toothed plate 27 and the second toothed plate 28 are both fixedly connected to a sealing plate 29, an observation window 30 is fixedly installed inside the front of the sealing plate 29, and the back of the sealing plate 29 is movably connected to the front of the housing 1.
[0048] When the first toothed plate 27 and the second toothed plate 28 move in opposite directions, they will drive the two sealing plates 29 to move, ultimately releasing the sealing effect on the front of the casing 1.
[0049] In some examples, a limiting block 32 is fixedly connected to the back of the enclosure 29, and the outer surface of the limiting block 32 is movably connected to the interior of the front of the housing 1.
[0050] Due to the limiting effect of the housing 1, the sealing plate 29 will drive the limiting block 32 to move horizontally left and right.
[0051] The working principle and usage process of this disclosure are as follows:
[0052] After the workpiece is placed on top of the platform 2, the second motor 24 is started, which will cause the rotating rod 25 to drive the gear 26 to rotate. At this time, under the limiting action of the second limiting rod 31, the first toothed plate 27 and the second toothed plate 28 will move horizontally towards each other. Finally, the two sealing plates 29 will drive the two limiting blocks 32 to move horizontally towards each other under the limiting action of the housing 1. When the two sealing plates 29 are in contact, the front of the housing 1 will be sealed, preventing the debris from splashing from the front of the housing 1 during subsequent processing.
[0053] Then, by starting the drive motor 13 and the first motor 18, the machining tool body 22 is moved to the designated machining position. Then, the pneumatic cylinder 21 is activated, causing the machining tool body 22 to move vertically downwards. Finally, when the machining tool body 22 contacts the workpiece, machining operations begin. After the machining operation is completed, the drive motor 13 and the first motor 18 are started again to reset the worktable 2 and the machining tool body 22. The power motor 4 is then started. At this time, the rotating shaft 5 drives the rotating rod 6 to rotate, causing the rotating rod 6 to press and push the hollow rod 7. The hollow rod 7 then drives the connecting rod. Under the limiting action of the platform 2, the 8 moves horizontally to the left, which eventually causes the push plate 9 to push the processing debris along the top of the platform 2 into the inside of the collection box 11. This realizes the function of centralized collection of processing debris, avoiding excessive accumulation of debris that affects subsequent processing operations. At the same time, it eliminates the need for operators to clean regularly, reducing the risk of safety accidents and the labor intensity of operators. After the processing debris is collected, the second motor 24 is started again, causing the two closed plates 29 to move horizontally in opposite directions and open. At this time, the operator can directly take out the collection box 11.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
