Description

Technical Field

[0001] The invention relates to the field of welding rod quality detection, and more specifically to a cobalt-based alloy welding rod quality detection device. Background Art

[0002] Cobalt-based alloy welding rod is a kind of welding material with excellent heat resistance, corrosion resistance and oxidation resistance. After the production of welding rod is completed, it is necessary to carry out sampling quality inspection on the welding rod. The detection of coating eccentricity in welding rod quality inspection is an important indicator of whether the welding rod is qualified.

[0003] Traditional welding rod eccentricity detection usually uses manual visual observation methods. Workers measure the maximum and minimum offsets between the outer side of the welding rod coating and the center of the welding core by naked eye to calculate the eccentricity. This detection method has low accuracy and increases the workload of workers. Summary of the invention

[0008] Furthermore, the end of the clamping plate close to the rack and away from the second ring body is a 45° inclined surface, and the vertical section of a single tooth shape of the rack is a right triangle inclined toward the second ring body, so that the movement of the shell away from the welding core is restricted.

[0009] Furthermore, an annular protrusion is provided at one end of the second screw rod close to the first compression spring, and the clamping plate matches the groove, so that the second screw rod can drive the clamping plate to move, and the clamping plate can be inserted into the middle of the groove.

[0010] Furthermore, the elastic coefficient of the second compression spring is smaller than the elastic coefficient of the third compression spring, and the lower end of the columnar block is an arc surface, so that the second compression spring is not likely to cause the columnar block to overcome the third compression spring and enter the middle of the shell, and the columnar block is not likely to damage the drug coating.

[0011] Furthermore, a side of the first screw rod close to the friction block is located in the middle of the friction block, and an end of the first screw rod close to the friction block is provided with a cylindrical protrusion, so that the first screw rod can drive the friction block to move.

[0012] Furthermore, the first vertical rod and the outer side of the shell are marked with scale lines, and the inner material of the friction block is wear-resistant rubber, so that the staff can calculate the eccentricity of the welding rod through the first vertical rod and the scale lines on the outer side of the shell, and the friction block is not easily damaged.

[0013] Furthermore, the shell passes through the second ring body, and the first vertical rod passes through the first ring body and contacts the surface of the coating, so that the shell and the first vertical rod can measure data through the scale line.

[0034] See also Figure 2-8The first limiting device 7 includes a first bracket 701, a through hole 702 is provided in the middle of the first bracket 701, first limiting frames 703 are fixedly connected at both ends of the first bracket 701, friction blocks 704 are slidably connected at the middle of both ends of the first bracket 701, and a first screw 705 is threadedly connected at the middle of the first limiting frame 703, so that the maximum offset distance of the coating 5 can be measured. The end of the side of the clamping plate 1002 close to the rack 1009 away from the second ring body 9 is an inclined surface inclined at 45°, and the vertical section of a single tooth shape of the rack 1009 is a right triangle inclined toward the second ring body 9, so that the movement of the housing 1012 away from the welding core 4 is limited.

[0035] See also Figure 7-9 The second screw 1006 has an annular protrusion at one end close to the first compression spring 1004, and the clamping plate 1002 matches the groove 1008, so that the second screw 1006 can drive the clamping plate 1002 to move, and the clamping plate 1002 can be inserted into the middle of the groove 1008. The elastic coefficient of the second compression spring 1010 is smaller than the elastic coefficient of the third compression spring 1013, and the lower end of the columnar block 1014 is an arc surface, so that the second compression spring 1010 is not likely to cause the columnar block 1014 to overcome the third compression spring and enter the middle of the housing 1012, and the columnar block 1014 is not likely to damage the drug cover 5.

[0036] See also Figure 3-9 , the side of the first screw 705 close to the friction block 704 is located in the middle of the friction block 704, and the end of the first screw 705 close to the friction block 704 is provided with a cylindrical protrusion, so that the first screw 705 can drive the friction block 704 to move. The first vertical rod 8 and the outer side of the shell 1012 are marked with scale lines, and the internal material of the friction block 704 is wear-resistant rubber, so that the staff can calculate the eccentricity of the welding rod through the first vertical rod 8 and the scale lines on the outer side of the shell 1012, and the friction block 704 is not easily damaged. The shell 1012 passes through the second ring body 9, and the first vertical rod 8 passes through the first ring body 6 and contacts the surface of the coating 5, so that the shell 1012 and the first vertical rod 8 can measure data through the scale lines.

[0037] During the inspection, the staff randomly samples the cobalt-based alloy welding rods from a batch, removes the outer coating 5 of one end of the welding core 4 covered by the coating 5, and fixes the welding rod between the two clamp modules 2;

[0038] The first measuring structure is slid to one side of the coating 5 through the cross bar 3, so that the four first vertical rods 8 are in contact with the outer surface of the coating 5, and the first screw 705 is rotated so that the first screw 705 drives the friction block 704 to limit the first vertical rod 8 by rotation. At this time, the friction block 704 limits the first vertical rod 8 by friction, and pushes the first measuring structure to slide to the other side of the coating 5. When the first vertical rod 8 contacts the outer side of the coating 5 and there is a larger offset between the center of the welding core 4, the coating 5 pushes the first vertical rod 8 to move to a position away from the center of the welding core 4, and the first vertical rod 8 overcomes the friction of the friction block 704 and moves a corresponding distance. After that, the first vertical rod 8 continues to be limited by the friction block 704. When the movement of the first measuring structure is completed, the scale value S1 of the four first vertical rods 8 located on the outer surface of the first ring body 6 is recorded, and the maximum value after calculation is taken as the maximum offset;

[0039] The second measuring structure is slid to one side of the drug coating through the cross bar 3, so that the ends of the four columnar blocks 1014 are in contact with the outer surface of the drug coating 5. At this time, under the action of the second compression spring 1010 and the third compression spring 1013, the ends of the columnar blocks 1014 continue to contact with the outer surface of the drug coating 5, and because the elastic coefficient of the second compression spring 1010 is smaller than the elastic coefficient of the third compression spring 1013, the third compression spring 1013 makes the tray 1015 located at the bottom of the shell 1012, and the second screw 1006 is rotated so that the second screw 1006 drives the card plate 1002 away from the tip of one end of the second screw 1006 and contacts the rack 1009, pushing the second measuring structure to slide to the other side of the drug coating 5. When the columnar block 1014 contacts the outer side of the drug coating 5 and there is a smaller offset with the center of the welding core 4, under the action of the second compression spring 1010, the shell 1012 moves toward the welding core 4. Since the card plate 1002 is close to one side of the rack 1009 The end away from the second ring body 9 is a slope with an angle of 45°, and the vertical section of a single tooth shape of the rack 1009 is a right triangle inclined toward the second ring body 9, so the shell 1012 is not restricted in moving toward the direction close to the welding core 4, and the tray 1015 is still located at the bottom of the shell 1012 at this time. When the cylindrical block 1014 contacts the outer side of the coating 5 and the center of the welding core 4 during movement, and there is an offset greater than the contact during the previous movement, since the end of the side of the clamping plate 1002 close to the rack 1009 away from the second ring body 9 is a slope with an angle of 45°, and the vertical section of a single tooth shape of the rack 1009 is a right triangle inclined toward the second ring body 9, the shell 1012 is restricted in moving away from the welding core 4. At this time, the coating 5 pushes the cylindrical block 1014 to move toward the inside of the shell 1012. When the movement of the second measuring structure is completed, the scale values ​​S2 of the four shells 1012 on the outer surface of the second ring body 9 are recorded, and the minimum value is taken as the minimum offset after calculation;

[0040] The eccentricity value of the welding rod is calculated by the maximum offset and the minimum offset, and the eccentricity value of the batch of welding rods is estimated by performing the above operation on multiple samples. The maximum offset between the outer side of the coating 5 and the center of the welding core 4 can be detected by the first measuring structure, and the minimum offset between the outer side of the coating 5 and the center of the welding core 4 can be detected by the second measuring structure, thereby improving the accuracy of welding rod eccentricity detection and reducing the workload of staff.

[0041] The above is only a preferred specific implementation of the present invention; however, 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 solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
