Description

Technical Field

[0001] The invention relates to a plate hardness detection device, in particular to a hardness detection device for new material processing. Background Art

[0002] Hardness is a professional term in physics. The ability of a material to resist the penetration of a hard object into its surface is called hardness. The local resistance of a solid to the invasion of an external object is an indicator for comparing the hardness of various materials. Due to different test methods, there are different hardness standards. The mechanical meanings of various hardness standards are different and they cannot be directly converted to each other, but they can be compared through experiments.

[0003] At present, the hardness of plates is usually measured by the indentation method (Brinell, Rockwell, Vickers). The hardness value indicates the ability of the material surface to resist the plastic deformation caused by another object pressing into it. The calculation of the hardness is related to the indentation distance and the indentation area, and the indoor temperature also has a certain influence on the experimental results. The current plate hardness test requires manual detection for the measurement of the indentation distance, which has large errors and is cumbersome to operate. In addition, the existing plate hardness measuring devices on the market have complex structures, high energy consumption, and poor detection effects.

[0004] In order to improve product quality, simplify the testing process and improve testing efficiency, we need to design a hardness testing device for new material processing that can automatically clamp, quickly and accurately test hardness, and quickly collect and take materials.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0026] Example 1

[0027] A hardness testing device for new material processing, such as Figure 1-4 As shown, it includes a first link rod 1, a knocking block 2, a first compression spring 3, a second compression spring 4, a knocking mechanism 5 and a transmission mechanism 6. The transmission mechanism 6 is provided below the knocking mechanism 5, and the transmission mechanism 6 cooperates with the knocking mechanism 5. The first link rod 1 is provided on the rear side of the knocking mechanism 5. A knocking block 2 is slidably provided in the first link rod 1. The first compression spring 3 is wound around the upper part of the knocking block 2. The upper and lower ends of the first compression spring 3 are respectively connected to the knocking block 2 and the knocking mechanism 5. The second compression spring 4 is wound around the lower part of the knocking block 2. The upper and lower ends of the second compression spring 4 are respectively connected to the knocking mechanism 5 and the knocking block 2.

[0028] When people need to test the hardness of the plate, they can use a hardness testing device for new material processing. First, put the plate into the transmission mechanism 6, and then start the transmission mechanism 6. The transmission mechanism 6 drives the plate to move backward. When the transmission mechanism 6 component contacts the knocking mechanism 5 component, it drives the knocking mechanism 5 component to flip up and down. When the knocking mechanism 5 component flips down, it drives the knocking block 2 to contact the plate and move upward, so that the first compression spring 3 and the second compression spring 4 are compressed, and the knocking block 2 will knock the plate, thereby achieving the purpose of automatically detecting the hardness of the plate. After the detection, the first compression spring 3 and the second compression spring 4 are reset, driving the knocking block 2 to move downward until it is reset. When the hardness test of the plate is not needed, the transmission mechanism 6 can be closed. The above actions can be repeated to test the hardness of the next plate.

[0029] The striking mechanism 5 includes a first fixed block 51, a rotating rod 52, a link block 53, a first wedge block 54 and a first torsion spring 55. A link block 53 is provided between the upper and lower ends of the first link rod 1, a rotating rod 52 is rotatably provided between the front sides of the link block 53, the left and right parts of the rotating rod 52 are symmetrically provided with first wedge blocks 54, the left and right ends of the rotating rod 52 are symmetrically provided with first fixed blocks 51, the left and right ends of the rotating rod 52 are both wound with first torsion springs 55, and the two ends of the two first torsion springs 55 are respectively connected to the first wedge block 54 and the first fixed block 51.

[0030] When people need to test the hardness of the plate, they first put the plate in the transmission mechanism 6, manually push the first wedge block 54 forward, and the first torsion spring 55 is compressed and twisted, thereby driving the link block 53 to flip upward through the rotating rod 52, and then driving the knocking block 2 to flip upward. After letting go, the first torsion spring 55 is reset, driving the link block 53 and the knocking block 2 to flip downward, so that the knocking block 2 contacts the plate, so that the purpose of hardness testing of the plate can be achieved.

[0031] The transmission mechanism 6 includes a support frame 61, a rotating shaft 62, a servo motor 63, a pulley 64, a transmission belt 65 and a second wedge block 66. The support frames 61 are symmetrically provided at the lower ends of the two first fixed blocks 51. The rotating shaft 62 is rotatably provided on both sides of the upper front and rear of the two support frames 61. The servo motor 63 is installed on the right end of the front rotating shaft 62. Pulleys 64 are provided on the left and right sides of the rotating shaft 62. A transmission belt 65 is connected between the two pulleys 64 on the same side. Four second wedge blocks 66 are evenly arranged on the transmission belt 65, and the second wedge blocks 66 are intermittently in contact with the first wedge blocks 54 on the same side.

[0032] When people need to test the hardness of the plate, start the servo motor 63, and the motor output shaft drives the rotating shaft 62 to operate, thereby driving the pulley 64 to operate, and then driving the transmission belt 65 to operate, and then driving the second wedge block 66 to operate. When the second wedge block 66 contacts the first wedge block 54, it drives the knocking mechanism 5 to flip upward, and then drives the knocking block 2 to knock the plate. In this way, the effect of automatic hardness testing of the plate can be achieved. When the hardness test of the plate is not needed, the servo motor 63 can be turned off.

[0033] Example 2

[0034] On the basis of Example 1, Figure 5-8 As shown, it also includes a clamping mechanism 7, which includes a slide plate 71, a fixed frame 72, a link frame 73, a second link rod 74, a tightening block 75 and a second torsion spring 76. The slide plates 71 are symmetrically arranged on the upper front sides of the two support frames 61, and four fixed frames 72 are evenly arranged between the two transmission belts 65. Link frames 73 are symmetrically arranged on the left and right sides of the fixed frames 72. Second link rods 74 are rotatably arranged between the upper parts of the link frames 73. A tightening block 75 is arranged in the middle of the second link rod 74, and the inner side of the tightening block 75 cooperates with the slide plate 71. Second torsion springs 76 are wound around the front and rear sides of the second link rod 74, and both ends of the second torsion spring 76 are respectively connected to the tightening block 75 and the link frame 73.

[0035] After the motor is started, the transmission belt 65 drives the fixing frame 72 to move backward, thereby driving the link frame 73 to move backward. When the link frame 73 moves to contact the lower part of the slide plate 71, the clamping block 75 is pressed and pushed open to turn outward, causing the second torsion spring 76 to twist and deform. When the link frame 73 moves to contact the corresponding slot on the upper part of the slide plate 71, the second torsion spring 76 is reset, and the clamping block 75 is pressed to turn inward to clamp the plate, thereby achieving the purpose of clamping the plate.

[0036] It also includes a material receiving mechanism 8, which includes a second fixed block 81, a loading frame 82, a pulling rope 83 and a sliding plate 84. The second fixed blocks 81 are symmetrically arranged on the rear side of the lower part of the two support frames 61, and a loading frame 82 is rotatably arranged in the rear part between the two second fixed blocks 81. A pulling rope 83 is connected between the upper front side of the loading frame 82 and the upper rear side of the support frame 61, and a sliding plate 84 is symmetrically arranged on the middle and lower part of the front wall of the loading frame 82.

[0037] When the plate after hardness testing moves backward with the link frame 73 until it contacts the sliding plate 84, the plate will move backward with the sliding plate 84 and slide into the loading frame 82. When the plate needs to be taken out, the pulling rope 83 is manually untied to make the loading frame 82 flip backward and downward, and the plate slides out of the loading frame 82, achieving the effect of quickly collecting and taking materials. After taking out the plate, the loading frame 82 is flipped up by the manual pulling rope 83, and then the pulling rope 83 is tied tightly.

[0038] It also includes a moving mechanism 9, which includes a third fixed block 91, a threaded rod 92 and a moving wheel 93. The third fixed blocks 91 are symmetrically provided on the front and back parts of the lower side of the support frame 61. The third fixed block 91 is threadedly provided on the outside and inside of the third fixed block 91, and a moving wheel 93 is provided at the bottom end of the threaded rod 92.

[0039] Manually rotate the threaded rod 92, the threaded rod 92 moves downward, thereby driving the moving wheel 93 to move downward, so that the support frame 61 leaves the ground, and the support frame 61 can move freely with the moving wheel 93. Then manually reverse the threaded rod 92, the threaded rod 92 moves upward, thereby driving the moving wheel 93 to move upward, so that the support frame 61 contacts the ground and is placed firmly. In this way, the purpose of easily and conveniently performing hardness testing on any plate can be achieved.
