[0002] In the quality evaluation of welding process, the processing quality of welding joint impact specimen is very important. The traditional welding joint impact specimen processing device and method have a series of problems that need to be solved.

The width and thickness of the specimen meet the specification size requirements, and the length reserved size is 80-120mm. In terms of processing length control, the traditional processing method first requires three positioning markings and two positioning cuts on the test specimen, and then the specimen is manually pushed for cutting. This measurement method is complicated and has poor accuracy.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Embodiment 1:

[0029] Reference Figure 1 - Figure 7 , a welding joint impact specimen processing device, comprising a main body component and a cutting component:

[0030] The main assembly is composed of four support columns 1, a motor 2, a screw rod 3, and a slide rod 18. The four support columns 1 are stacked, the two ends of the screw rod 3 are rotatably connected to two of the support columns 1, the two ends of the slide rod 18 are fixedly connected to the other two support columns 1, the motor 2 is installed on the outer wall of one of the support columns 1, and the output shaft of the motor 2 is fixedly connected to the screw rod 3;

[0031] The cutting assembly is composed of a slider 10, two groups of first piston cylinders 7, two groups of first springs 8, two groups of first piston rods 9, a fixed block 1002, a second motor 1001, a transmission shaft 1003 and a cutting blade 1004, wherein two support columns 1 are provided with sliding grooves 6, two groups of first piston cylinders 7 are respectively arranged in the two sliding grooves 6, the first piston rod 9 is slidably connected to the inner wall of the first piston cylinder 7, one end of the first spring 8 is fixedly connected to the inner wall of the first piston cylinder 7, and the other end is fixedly connected to the lower end of the first piston rod 9, the upper ends of the two first piston rods 9 are commonly fixedly connected to the lower end of the slider 10, the slider 10 is slidably connected to the two sliding grooves 6, the fixed block 1002 is fixedly connected to the lower end of the slider 10, the second motor 1001 is installed on the outer wall of the fixed block 1002, the output shaft of the second motor 1001 is fixedly connected to the transmission shaft 1003, and the cutting blade 1004 is fixedly connected to the axial outer wall of the transmission shaft 1003;

[0032] The side walls of the four support columns 1 are fixedly connected with a placement plate 4 , and a placement groove 201 is formed at the upper end of the placement plate 4 .

[0033] In this embodiment, the welding joint to be cut is first placed in the placement groove 201, and the part of the welding joint to be cut is pushed out of the placement groove 201, and then the second motor 1001 is started. The output shaft of the second motor 1001 drives the transmission shaft 1003 to rotate, thereby causing the cutting blade 1004 fixed on the axial outer wall of the transmission shaft 1003 to rotate at high speed, and at this time, the slider 10 is pressed to move downward. When the slider 10 moves downward, the first piston rod 9 will slide in the first piston cylinder 7, compressing the first spring 8, thereby playing a shock absorbing and protective role when cutting the welding joint, thereby improving the accuracy of cutting and avoiding cracks. Then, when the welding joint is cut, stop pressing the slider 10, and the first spring 8 is reset at this time, thereby pushing the slider 10 to reset and completing the cutting.

[0034] Embodiment 2:

[0035] Reference Figure 1 - Figure 7 Compared with the first embodiment, in this embodiment, the upper end of the slider 10 is fixedly connected to a fixed plate 11, the side wall of the fixed plate 11 is fixedly connected to a slider 12, a slide groove 13 is provided on the slider 12, a T-shaped slider 14 is slidably connected to the slide groove 13, a second piston cylinder 15 is fixedly connected to the side wall of the fixed plate 11, a second piston rod 16 is slidably connected to the inner wall of the second piston cylinder 15, and a second spring 17 is provided on the outer sleeve of the second piston rod 16;

It should be noted that the origin position of the T-shaped slider 14 is the middle position of the placement groove 201, and it should be noted that the lower end of the V-shaped block 1404 is provided with a printed cloth with ink.

[0037] In this embodiment, when the slider 10 moves downward and drives the cutting blade 1004 to cut the welding joint, it will synchronously drive the slider 12 through the fixed plate 11. When the slider 12 moves downward, it will drive the T-shaped slider 14 downward, thereby driving the telescopic cylinder 1401 downward and driving the telescopic rod 1402 downward, and then driving the V-block 1404 downward. When the V-block 1404 contacts the welding joint, it will apply a downward pressure on the welding joint to ensure that the welding joint will not move. At the same time, the welding joint will be marked with a V-shape through the ink on the V-block 1404, so as to facilitate the positioning when opening the V-groove in the next step. When the slider 10 moves downward, the telescopic rod 1402 slides in the telescopic cylinder 1401, thereby avoiding blocking the cutting blade 1004 from cutting the welding joint. When the cutting is completed, the slider 10 is reset and the V-block 1404 is reset under the action of the reset spring 1403.

[0038] Embodiment three:

[0039] Reference Figure 1 - Figure 7 Compared with the second embodiment, in this embodiment, a side wall of one of the support columns 1 is fixedly connected to a support plate 19, an upper end of the support plate 19 is rotatably connected to a first rotating shaft 503, an upper end of the support plate 19 is rotatably connected to a second rotating shaft 505, an axial outer wall of the first rotating shaft 503 is fixedly connected to a first gear 502, an axial outer wall of the second rotating shaft 505 is fixedly connected to a second gear 504, an axial outer wall of the second rotating shaft 505 is fixedly connected to a differential gear 507, and a support The upper end of the plate 19 is provided with an L-shaped slide groove 1901, the L-shaped slide groove 1901 is slidably connected with the second rack 506, the screw rod 3 is threadedly connected with the push plate 5, the slide rod 18 is slidably connected with the push plate 5, the upper end of the push plate 5 is fixedly connected with the rack 501, the rack 501 is meshed with the first gear 502, the first gear 502 is meshed with the second gear 504, the differential gear 507 is meshed with the second rack 506, and the upper end of the second rack 506 is fixedly connected with the transmission rod 508;

[0040] The side walls of the two support columns 1 are fixedly connected with support blocks 101, and the upper ends of the two support blocks 101 are commonly fixedly connected with a measuring ruler 102. It should be noted that the starting point of the push surface of the push plate 5 is the starting point of the placement groove 201. It should be noted that the tooth ratio of the first gear 502 and the second gear 504 is 2:1. It should be noted that the tooth ratio of the differential gear 507 and the first gear 502 is 1:1. It should be noted that the transmission rod 508 is located at the front end of the T-shaped slider 14. It should be noted that the measurement starting point of the measuring ruler 102 is the push surface of the push plate 5.

[0041] In this embodiment, the weld joint to be cut is placed in the placement groove 201, and the motor 2 is started according to the measuring ruler 102, and the output shaft of the motor 2 drives the screw rod 3 to rotate. Since the push plate 5 cooperates with the screw rod 3 through threads and is slidably connected with the slide rod 18, when the screw rod 3 rotates, the push plate 5 will move linearly along the slide rod 18 and the screw rod 3, thereby pushing the weld joint to the specified length required for cutting;

[0042] At the same time, when the push plate 5 moves, since the rack 501 fixedly connected to the upper end of the push plate 5 meshes with the first gear 502, when the push plate 5 moves, the rack 501 drives the first gear 502 to rotate, and the first gear 502 meshes with the second gear 504. The rotation of the first gear 502 drives the second gear 504 to rotate. When the second gear 504 rotates, it drives the differential gear 507 to rotate. Since the differential gear 507 meshes with the second rack 506, when the second gear 504 rotates, it drives the second rack 506 to slide in the L-shaped slide groove 1901 through the differential gear 507. When the second rack 506 moves, it pushes the T-shaped slider 14 through the transmission rod 508, thereby driving the telescopic cylinder 1401 and the V-shaped block 1404 below to move horizontally. At the same time, when the T-shaped slider 14 moves, it also pushes the second piston cylinder 15. When the second piston cylinder 15 moves, the second piston rod 16 inside it contracts under the pressure. The transmission ratio of gear 502 and the second gear 504 is 2:1. When the first gear 502 rotates one circle, the second gear 504 rotates half a circle, and can only drive the differential gear 507 to rotate half a circle. Since the tooth number ratio of the differential gear 507 and the first gear 502 is 1:1, the transmission ratio of the push plate 5 and the transmission rod 508 is 2:1, so that the moving distance of the T-shaped slider 14 is only half of the push plate 5, so that the T-shaped slider 14 is always in the middle position of the welding joint with the required retained length, so that the positioning position of the V-block 1404 is at the center point of the welding joint to avoid eccentricity during grooving.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
