Description

Technical Field

[0001] The utility model belongs to the technical field of detection devices, and in particular relates to a rock wool board tensile strength detection mechanism. Background Art

[0002] Rock wool board is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. After production and preparation, the rock wool board needs to be tested for its tensile properties by a tensile testing agency.

[0003] The Chinese utility model patent with announcement number CN212432766U discloses a rock wool board tensile strength testing mechanism, comprising a support platform, two fixed blocks fixedly connected to the top of the support platform, a control rod rotatably connected between the fixed blocks, a scale fixedly connected between the two fixed blocks, and two movable blocks threadedly connected to the control rod. The utility model, by providing a first control gear and a second control gear, can achieve the following: when the rock wool board is initially stretched, the first control gear and the transmission gear cooperate to drive the control rod to rotate, thereby achieving the two movable blocks to move at a relatively fast speed. When the pulling force gradually increases, the second control gear and the transmission gear cooperate to achieve the two movable blocks to move at a relatively slow speed, thereby achieving precise control of the rock wool board, and avoiding the situation where the two movable blocks move too much when the rock wool board is broken, resulting in inaccurate final measurement data.

[0004] However, the above device has the following technical problems when actually used:

[0005] 1. The above-mentioned device fixes the rock wool board by placing the two ends of the rock wool board in two oppositely arranged movable blocks and moving the fixed plate downward. However, this fixing method can only fix the rock wool board from both ends, and the clamping range is small. In addition, when the two movable blocks move away from each other during actual testing, the rock wool board will generate a reverse contraction force, which will cause the end of the rock wool board to easily fall off from the clamping mechanism, which is not conducive to actual testing.

[0006] Second, in addition, the above device can only detect the tensile properties of the rock wool board in the horizontal direction, and cannot perform separate detection on a specific position on the rock wool board. The detection method is relatively simple. Utility Model Content

[0034] Specifically, in order to avoid damaging the surface of the rock wool board body when clamping it, protrusions are provided on the first pressure plate 224, the second pressure plate 237, the inner bottom wall of the first clamping groove 222, and the inner bottom wall of the second clamping groove 236. The protrusions are made of rubber material. On the one hand, they can reduce hard scratches on the outer surface of the rock wool board body, and on the other hand, they can also increase the friction between the rock wool board body and the rock wool board body, thereby preventing the rock wool board body from falling off.

[0035] Furthermore, the driving component 21 includes: a first movable groove 211 opened on the workbench 1, a bidirectional screw 212 is rotatably connected in the first movable groove 211, a first motor 213 is also fixedly connected to the side wall of the workbench 1, and its output end is fixedly connected to one end of the bidirectional screw 212, and two sliders 214 are also slidably connected in the first movable groove 211, and the two sliders 214 are symmetrically arranged and are respectively screwed on two opposite thread segments of the bidirectional screw 212.

[0036] Furthermore, the first stretching assembly 22 includes: a first clamping seat 221 is fixedly installed on each of the two sliders 214, and a first clamping groove 222 that can accommodate the end of the rock wool board body is opened on the side walls adjacent to the two first clamping seats 221, and a first adjusting screw 223 is threadedly connected to the top wall of the first clamping seat 221, and the bottom end of the first adjusting screw 223 is movably connected to the top wall of the first pressure plate 224 arranged in the first clamping groove 222.

The inner diameter of the through hole matches the outer diameter of the first adjusting screw 223 (second adjusting screw 238), and the inner diameter of the through hole is smaller than the size of the inner cavity of the protrusion. At the same time, the bottom end of the first adjusting screw 223 (second adjusting screw 238) passes through the through hole and is located in the inner cavity of the protrusion, and the first adjusting screw 223 (second adjusting screw 238) is located on the outer wall of the inner cavity of the protrusion and a limit block is fixedly installed. The outer diameter of the limit block is larger than the inner diameter of the through hole (so the limit block will not detach from the protrusion). When the first adjusting screw 223 (second adjusting screw 238) is rotated, the limit block follows the rotation and plays a limiting role, thereby pulling the first pressure plate 224 and the second pressure plate 237 up and down according to the first adjusting screw 223 (second adjusting screw 238).

[0041] Specifically, the strip-shaped pressing block 46 is in a strip shape and can cover a larger range when pressed downward, thereby achieving deformation testing of the ductility and tensile properties of the surface of the rock wool board body at a specific position.

[0042] The working principle and use process of this utility model:

[0043] The output end of the first motor 213 controls the rotation of the bidirectional screw 212, which drives the two first clamping seats 221 to move relative to each other through the sliders 214 on both sides, so that the two ends of the rock wool board body are respectively placed in the first clamping grooves 222 on both sides. Then, the first adjusting screw 223 is rotated to control the first pressing plate 224 to move downward, so that the first pressing plate 224 is pressed on the end of the rock wool board;

[0044] At the same time, on each first clamping seat 221, the connecting plate 234 is pulled toward the two side edges of the rock wool board body, so that it drives the second clamping seat 235 to move to the side edge of the rock wool board. Then, the side edge of the rock wool board body is inserted into the second clamping groove 236. At the same time, the second adjusting screw 238 is rotated to drive the second pressing plate 237 to move downward and press on the side edge of the rock wool board end.

[0045] Subsequently, the first clamping seats 221 on both sides move away from each other to perform a tensile test on the rock wool board body;

[0046] Then, the second motor 43 is used to control the rotation of the driving screw 42. After the driving screw 42 controls the moving block 44 to move to the specified position, the output end of the telescopic cylinder 45 extends to push the strip pressure block 46 down to the specified position on the rock wool board body, and the specified position is deformed.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
