Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices for processing, and in particular to a cutting device for processing parts used in mechanical engineering. Background Art

[0002] Parts usually refer to the components of industrial products. When parts are produced and processed, they need to be cut. The structures of existing part cutting devices are relatively simple and their functions are relatively single. They do not have the function of polishing the cutting surface during operation. Therefore, we propose a cutting device for processing parts used in mechanical engineering.

[0003] Currently, during the cutting process of the cutting devices on the market, only vertical cutting operations can be performed. Therefore, when inclined cutting is required subsequently, the cutting device needs to be adjusted and the metal parts need to be repositioned. This process not only increases the time cost of cutting but also increases the chance of cutting errors.

[0004] Secondly, after the cutting operation is completed, the cutting opening needs to be polished to ensure the subsequent welding effect. However, few devices on the market perform grinding operations on the parts after cutting, which affects the subsequent welding or connection.

[0005] In addition, most of the conveying devices on the market use manual conveying by workers, which results in small errors in the cut metal parts, so secondary cutting is required subsequently.

[0006] Therefore, we specifically propose a cutting device for processing parts used in mechanical engineering. Summary of the Invention

[0044] 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.

[0045] Please refer to Figures 1 to 11 , the present invention provides a technical solution:

[0046] A cutting device for machining parts in mechanical engineering, including a fixed installation table 1. The fixed installation table 1 has a T-shaped structure. And, horizontally symmetric support legs 2 are fixedly installed on the lower end surface of the fixed installation table 1. With the support of the support legs 2, the fixed installation table 1 can be kept away from the ground. Then, a first U-shaped frame 3 is fixedly installed alone on the left side surface of the fixed installation table 1. Two symmetric springs 5 are fixedly installed on the lower left end surface of the first U-shaped frame 3. And a discharge plate 4 is fixedly installed on the lower end surface of the spring 5. The front and rear sides of the right end of the discharge plate 4 are rotatably installed on the lower end surface of the first U-shaped frame 3, as Figure 1 shown.

[0047] During the operation, the cut metal part 16 will fall into the interior of the discharge plate 4. Under the action of the spring 5, the discharge plate 4 can move downward and then upward, thereby reducing the height of the downward movement of the metal part 16 to ensure the safety of the cut metal part 16. Then, it slides downward along the inclined angle of the discharge plate 4 to complete the automatic discharging operation.

[0048] Then, on the upper left end face of the fixed installation table 1, a limit plate 6 is fixedly installed. Inside the limit plate 6, four first sliding grooves 601 are evenly arranged in a circular array. Then, inside the limit plate 6, on one side of the first sliding groove 601, gear grooves 602 are arranged, and an annular groove 603 is arranged inside the limit plate 6, as Figure 6 shown.

[0049] Inside the first sliding groove 601, a rack bar 606 is slidably installed. Inside the gear groove 602, a first gear 608 is rotatably installed. It should be noted that both ends of the first gear 608 are rotatably installed on the inner wall of the limit plate 6, so as to ensure that the first gear 608 will not collide with the gear groove 602. Then, inside the annular groove 603, a gear ring 609 is rotatably installed. Finally, at one end inside the rack bar 606, first clamping plates 607 are fixedly installed. The first gear 608 meshes with the toothed end of the adjacent rack bar 606, and the first gear 608 also meshes with the gear ring 609.

[0050] On the right side surface of the limit plate 6, a first motor 605 is fixedly installed, and the output shaft of the first motor 605 is fixedly connected to the central position of the adjacent first gear 608.

[0051] During use, when the first motor 605 is started, the output shaft of the first motor 605 will drive the fixedly connected first gear 608 to rotate. At this time, the rotating first gear 608 will drive the gear ring 609 and the engaged rack bar 606 to rotate. The gear ring 609 will drive the other three first gears 608 to rotate synchronously. As a result, the first gear 608 will drive the rack bar 606 to slide. During the sliding process of the rack bar 606, it will drive the first clamping plate 607 to move. During the movement of the first clamping plate 607, it can clamp the metal part 16 sliding in the through hole 604 opened inside the limit plate 6, so as to ensure that the metal part 16 is in a centered state, thereby ensuring the subsequent cutting operation, and ensuring that during the cutting process, the metal part 16 will not vibrate greatly, thus ensuring the smoothness of the cutting operation and ensuring that there will be no large misalignment after cutting.

[0052] Then, convex chute rods 7 in a front-back symmetric state are fixedly installed on both the right side and the left side of the limit plate 6, as Figure 1 shown.

[0053] At the upper part of one end of each convex chute rod 7 close to the limit plate 6, a second motor 12 is fixedly installed. On the output shaft of each second motor 12, a first adjusting rod 10 is fixedly installed. One end of the first adjusting rod 10 far from the second motor 12 is rotatably installed with a second adjusting rod 11. One end of the second adjusting rod 11 far from the first adjusting rod 10 is rotatably installed with a first sliding table 9. The first sliding table 9 has a convex structure and is slidably installed inside the convex chute rod 7. A through groove 8 is formed on the inner wall surface of the convex chute rod 7, and the through groove 8 is in a through state with the inside of the convex chute rod 7, as Figure 4 shown.

[0054] One end of the two adjacent first sliding tables 9 on the right side passes through the through groove 8 and is jointly fixedly installed with a first mounting ring 13. On the outer circumferential surface of the first mounting ring 13, first telescopic pumps 14 are fixedly installed in a uniformly annular array. Among them, the telescopic rods of the first telescopic pumps 14 pass through the first mounting ring 13 and are located inside the first mounting ring 13. And on the telescopic rods of the first telescopic pumps 14 located inside the first mounting ring 13, clamping arc-shaped rods 15 are fixedly installed, as Figure 5 shown.

[0055] During the use process, start the first telescopic pump 14. The telescopic rods of the first telescopic pump 14 drive the clamping arc-shaped rods 15 to move synchronously. The clamping arc-shaped rods 15 perform clamping operations on metal parts 16 with different diameters, making the metal parts 16 in a centered state.

[0056] Start the second motor 12. The output shaft of the second motor 12 drives the first adjusting rod 10 to rotate. During the rotation of the first adjusting rod 10, it will drive the second adjusting rod 11 to rotate synchronously. And during the movement of the second adjusting rod 11, it will drive the first sliding table 9 to slide inside the convex chute rod 7. In this way, the first adjusting rod 10 and the second adjusting rod 11 can form an inverted "V" shape structure during the operation process. And during the sliding of the first sliding table 9, it will drive the first mounting ring 13 to move synchronously. Furthermore, the first mounting ring 13 will drive the metal parts 16 to adjust the distance under the action of the clamping arc-shaped rods 15, making the distance of each movement the same.

[0057] Then, a third motor 17 is fixedly installed at a position near the edge of the top center of the limit plate 6. A reciprocating screw rod 18 is fixedly installed on the output shaft of the third motor 17. A second sliding table 19 is threadedly and rotatably installed on the circumferential surface of the reciprocating screw rod 18. The outer side of the lower end of the second sliding table 19 is rotatably installed with a cavity ring 20. It should be noted that the position where the second sliding table 19 and the cavity ring 20 are rotatably connected uses a damping structure for rotational connection. Therefore, during the rotation process, the position where the cavity ring 20 and the second sliding table 19 are rotatably connected will not automatically rotate. On the outer circumferential surface of the cavity ring 20, an adjusting gear 32 is rotatably and fixedly installed front and back. On the outer side surface of the adjusting gear 32, a moving block is rotatably installed. The moving block is slidably installed inside a through groove 8 formed on the inner surface of the adjacent left convex-shaped chute rod 7 front and back.

[0058] It should be noted that during the subsequent use process, it is necessary to rotate the adjusting gear 32 to drive the cavity ring 20 to rotate, so that the cavity ring 20 rotates from a vertical state to an inclined state to perform inclined plane cutting operations.

[0059] During the use process, the adjusting gear 32 can be manually rotated by hand, or a driving device such as a motor or other structural driving device can be fixedly installed inside the moving block to rotate the adjusting gear 32, and then rotate the cavity ring 20. However, the specific setting can be based on the actual situation, and this provides a basic reference operation here.

[0060] Then, moving ring grooves 21 are respectively formed on the left and right side surfaces of the cavity ring 20, and a convex ring groove 22 is formed on the inner circumferential surface inside the cavity ring 20, as Figure 9 shown, and tooth grooves 23 are formed on the left and right sides of the opening inside the convex ring groove 22.

[0061] Moving rods 24 are slidably installed inside the moving ring grooves 21. A connecting rod 25 is fixedly installed inside the lower ends of the two moving rods 24 together. A fourth motor 26 is fixedly installed on the top of the connecting rod 25. Second gears 27 are fixedly installed on the output shafts at both ends of the fourth motor 26. The second gears 27 are meshed with the tooth grooves 23. Then, a micro telescopic pump 28 is fixedly installed at the lower end of the connecting rod 25. A second U-shaped frame 29 is fixedly installed on the telescopic rod of the micro telescopic pump 28. Fifth motors 30 are fixedly installed on the outer sides of the lower ends of the second U-shaped frame 29. A cutting blade 31 is fixedly installed on the output shafts of the left and right fifth motors 30 together, as Figure 10 operation.

[0062] During the use process, the output shaft of the third motor 17 drives the reciprocating screw 18 to rotate. The reciprocating screw 18 drives the second slide table 19 to move. Due to the limitation of the cavity ring 20, the second slide table 19 can only move horizontally, and then drives the cavity ring 20 to move. Then, the fourth motor 26 is started. The output shaft of the fourth motor 26 drives the second gear 27 to rotate. Under the action of the second gear 27, the moving rod 24 can slide inside the moving ring groove 21, and then drives the connecting rod 25 to move synchronously. In this way, the connecting rod 25 can drive the micro telescopic pump 28 to rotate inside the cavity ring 20. The micro telescopic pump 28 drives the second U-shaped frame 29 to rotate synchronously. The second U-shaped frame 29 drives the fifth motor 30 and the cutting blade 31 to rotate synchronously, so as to perform cutting operations on the metal part 16. At this time, it is decided whether to start the micro telescopic pump 28 according to the situation, so that the second U-shaped frame 29 can move away from the connecting rod 25, and then the second U-shaped frame 29 drives the cutting blade 31 to change the cutting depth of the metal part 16, so as to completely perform cutting operations on the metal part 16.

[0063] Then, according to the requirements of the operation, the adjusting gear 32 is started. The adjusting gear 32 drives the cavity ring 20 to rotate, so as to perform subsequent inclined plane cutting operations.

[0064] Secondly, a second mounting ring 33 is fixedly installed between the interiors of the two first slide tables 9 on the left side of the limit plate 6. The outer side surface of the second mounting ring 33 is fixedly installed with second telescopic pumps 34 in a uniform annular array. The telescopic rods of the second telescopic pumps 34 pass through the second mounting ring 33 and are fixedly installed with polishing rods 35, as Figure 11 shown.

[0065] During the use process, after the cutting operation is completed, the left side surfaces of the cavity ring 20 and the limit plate 6 are closely attached.

[0066] At this time, under the action of the second motor 12, the first adjusting rod 10, the second adjusting rod 11 and the second slide table 19, the second mounting ring 33 can be gradually moved closer to the edge of the cut end of the metal part 16. After moving to a suitable position, the second telescopic pumps 34 are started clockwise or counterclockwise in sequence. The telescopic rods of the second telescopic pumps 34 drive the polishing rods 35 to perform deburring operations on the left end of the metal part 16 in sequence. After the operation is completed, a reset operation is performed.

[0067] Working principle: First, the operator slides one end of the metal part 16 through the through hole 604. At this time, the operator adjusts the initial position of the metal part 16 according to the required cutting distance to achieve the required movement distance.

[0068] At this time, the first motor 605 is started, and the first motor 605 drives the first gear 608 to rotate. The first gear 608 drives the gear ring 609 to rotate. The gear ring 609 drives the first gear 608 in the area to rotate. The first gear 608 drives the rack bar 606 to slide inside the first chute 601. The sliding of the rack bar 606 drives the first clamping plate 607 to stably clamp the metal part 16.

[0069] The fourth motor 26 drives the second gear 27 to rotate, which can then make the moving rod 24 rotate. The moving rod 24 drives the connecting rod 25. The connecting rod 25 drives the micro telescopic pump 28. The micro telescopic pump 28 drives the second U-shaped frame 29 to move. Under the action of the fifth motor 30, it can drive the cutting blade 31 to rotate. At this time, the cutting blade 31 cuts the metal part 16. The cut metal part 16 falls into the inside of the discharge plate 4 and then slides off.

[0070] At this time, under the action of the second motor 12, the first adjusting rod 10, the second adjusting rod 11 and the second sliding table 19, the second mounting ring 33 can gradually approach the edge of one end of the metal part 16 after being cut. After moving to a suitable position, start the second telescopic pump 34 clockwise or counterclockwise in sequence. The telescopic rod of the second telescopic pump 34 drives the grinding rod 35 to perform the grinding operation on the left end of the metal part 16 in sequence. After the operation is completed, perform the reset operation.

[0071] Start, the first telescopic pump 14 drives the clamping arc rod 15 to move. The clamping arc rod 15 clamps the metal part 16. At this time, the first clamping plate 607 releases the clamping and limitation of the metal part 16.

[0072] Under the action of the second motor 12, the first adjusting rod 10, the second adjusting rod 11 and the second sliding table 19, the clamping arc rod 15 can drive the metal part 16 to move the same distance, and then repeat the above steps.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
