Description

Technical Field

[0001] The invention belongs to the field of steel plate detection, in particular to a multi-point strength testing device for electromechanically manufactured steel plates. Background Art

[0002] The strength of steel plates is an important physical indicator that describes their ability to resist external forces. In electromechanical manufacturing, the strength of steel plates is crucial because it directly affects the performance, durability and safety of manufactured products.

[0003] In a Chinese patent with publication number CN110160886A, a stress detection device for welding steel plates is mentioned, including a workbench, a support seat is fixedly installed on the bottom surface of the workbench, and a box is fixedly installed on the top surfaces of both ends of the workbench. A first cylinder is embedded in the center of the bottom surface of the workbench, and the stress at the welding point at the right end of the steel plate body can be conveniently detected by moving the second cylinder to the right, and the threaded rod can be reversed to drive the second cylinder to move to the left. The stress at the welding point at the left end of the steel plate body can be conveniently detected by moving the second cylinder to the left.

The two groups of gears 28 are meshed, and the side wall of the gear 28 is rotatably connected to a clamping plate 29.

[0036] As can be seen from the above, by the rotation of the motor 3, the pulley 12 is driven to rotate when the motor 3 rotates, and the belt 14 between the pulleys 12 is used to make the three groups of pulleys 12 rotate in a synchronous state, and the rotation connection between the pulley 12 and the reciprocating screw 10 is used to make the pulley 12 drive the reciprocating screw 10 to rotate. It is worth noting that both ends of the reciprocating screw 10 are inside the limit plate 13, so as to ensure the normal rotation of the reciprocating screw 10, and the threaded connection between the reciprocating screw 10 and the slider 6 is used to make the sliders 6 on both sides relatively far away from each other. When the slider 6 moves, the two sides of the slider 6 contact the inner wall of the connecting seat 2 to achieve the effect of limiting the position of the slider 6. After the slider 6 moves to the appropriate position, the steel plate material is placed on the top of the slider 6. By pulling the pin 32, one end of the pin 32 is moved away from the interior of the slider 6, so that the arc plate 7 moves downward. It is worth noting that the two ends of the support rod 9 are fixedly connected to the interior of the slider 6. In order to ensure that the arc plate 7 moves downward normally, a groove is provided inside the arc plate 7, and the support rod 9 is located inside the groove. When the arc plate 7 moves downward, the support rod 9 limits the position of the arc plate 7 to avoid the situation where the arc plate 7 cannot move. By rotating the rotating plate 8, the rotating plate 8 drives the screw to rotate when rotating. The rotating connection between the rotating plate 8 and the fixed plate 31 is utilized to make the bottom of the fixed plate 31 contact the top of the steel plate material. At the same time, in order to ensure the friction effect between the fixed plate 31 and the steel plate material, an anti-slip pad is provided on the bottom of the fixed plate 31 to improve the friction between the fixed plate 31 and the steel plate The friction force of the material is achieved through the fixing effect between the fixed plate 31 and the steel plate material. Through the rotation of the motor 3, the motor 3 drives the reciprocating screw 10 to rotate. The threaded connection between the reciprocating screw 10 and the slider 6 is used to move the slider 6. The fixing effect between the slider 6 and the fixed plate 31 is used to achieve the stretching effect on the steel plate material, thereby realizing the stretching detection effect on the entire steel plate material. Through the reverse rotation of the motor 3, the motor 3 drives the reciprocating screw 10 to rotate, so that the side wall of the slider 6 is close to the side wall of the steel plate material. By pushing the arc plate 7 downward, the arc plate 7 and the steel plate material move downward synchronously. At the same time, when the arc plate 7 moves downward, the arc plate 7 pushes the reciprocating screw 10 to move downward, and the limit plate 13 on the side wall of the reciprocating screw 10 moves synchronously. The movable seat 30 is moved synchronously by the limit plate 13, and a rotating rod is provided in the movable seat 30, and the rotating rod is hinged and rolls inside the movable seat 30, and one side of the movable seat 30 is clamped in the inside of the groove plate 16 through the sliding connection between the movable seat 30 and the groove plate 16, and the limit plate 13 is fixed inside the connecting seat 2, and the support of the spring 11, the movable rod and the groove plate 16 are utilized.To achieve the overall fixing effect of the limit plate 13, to avoid the situation that the reciprocating screw 10 is damaged during the steel plate material inspection, by pulling the clamp ring 4, the clamp ring 4 drives the clamping plate 29 to move, to achieve the clamping connection between the clamping plates 29, by the rotation of the motor 3, the motor 3 drives the gear 28 on the side wall of the pulley 12 to rotate, by utilizing the gear meshing between the gears 28, the gear 28 drives the clamping plate 29 to rotate, by utilizing the gear 28 to drive the screw 23 to rotate, by utilizing the threaded connection between the screw 23 and the support seat 5, the support seat 5 is moved to a suitable position, the first connecting plate 19 is pushed downward by the cylinder 15, and the first connecting plate 19 and the second connecting plate are connected. The limit block 27 between the second connecting plate 20 and the first connecting plate 19 makes the second connecting plate 20 move synchronously with the first connecting plate 19. When the push rod 22 contacts the top of the steel plate material, the cylinder 15 is used to continuously push downward to make the push rod 22 extrude the steel plate material. At the same time, after the second connecting plate 20 contacts the top of the steel plate material, the bottom of the first connecting plate 19 contacts the top of the second connecting plate 20. The connection between the push rod 22 and the fixing ring 21 is used to increase the overall friction of the push rod 22. When the top of the steel plate material is slightly uneven, the steel plate material will push the push rod 22 to appear slightly uneven. The stress detection effect on the top of the steel plate material is achieved by detecting the height of the push rod 22 through the detection box 26.

[0037] Embodiment 2: This embodiment is basically the same as the previous embodiment, with the difference that a retaining ring 4 is provided in the connecting seat 2, one end of the screw rod 23 is rotatably connected to the side wall of the retaining ring 4, a gear 28 is provided on the side wall of the fixed seat 25, and two groups of gears 28 are provided. The two groups of gears 28 are meshed, and the side wall of the gear 28 is rotatably connected with a clamping plate 29.

[0038] From the above, it can be seen that by pulling the snap ring 4 in the reverse direction, the snap ring 4 drives the clamping plate 29 to separate, so that the support seat 5 cannot move. When the motor 3 rotates in the reverse direction, the snap ring 4 is pulled again, so that the snap ring 4 drives the clamping plate 29 to contact, thereby realizing the overall movement effect of the support seat 5 and the cylinder 15, thereby ensuring the overall detection effect of the steel plate material.

[0040] As can be seen from the above, the fixing ring 21 is driven by the push rod 22 so that the fixing ring 21 and the push rod 22 contact the inside of the second connecting plate 20. It is worth noting that the fixing ring 21 is sponge-shaped. When the fixing ring 21 is embedded in the inside of the second connecting plate 20, the different moving positions of the push rod 22 allow the steel plate material to be tested at different positions. When the test is completed, the second connecting plate 20 moves downward to move the push rod 22 downward. At the same time, the fixing ring 21 limits the position of the push rod 22 to prevent the push rod 22 from moving out of the inside of the second connecting plate 20.

When the slider 6 moves, the two sides of the slider 6 contact the inner wall of the connecting seat 2, so as to achieve the effect of limiting the position of the slider 6. After the slider 6 moves to the appropriate position, the steel plate material is placed on the top of the slider 6.

When the arc plate 7 moves downward, the support rod 9 limits the position of the arc plate 7 to avoid the situation where the arc plate 7 cannot move. By rotating the rotating plate 8, the rotating plate 8 drives the screw to rotate when rotating. The rotating connection between the rotating plate 8 and the fixed plate 31 is utilized to make the bottom of the fixed plate 31 contact the top of the steel plate material. At the same time, in order to ensure the friction effect between the fixed plate 31 and the steel plate material, an anti-slip pad is provided on the bottom of the fixed plate 31 to improve the friction between the fixed plate 31 and the steel plate The friction force of the material is achieved through the fixing effect between the fixed plate 31 and the steel plate material.
