[0002] The tensile test of building materials is a test method for determining the mechanical properties of materials by applying axial tensile load, which is mainly used for evaluating the key indicators such as strength, stiffness and ductility of materials. The test principle is that the sample is deformed by gradually increasing the tension until it breaks, and the stress-strain relationship of the material is measured during the process, and then the parameters such as elastic limit, tensile strength, yield strength and elongation are calculated. The test object is suitable for performance detection of building materials such as steel bars, insulation boards and water stops.

Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Examples, such as Figures 1-13 As shown, a testing device for the tensile strength of building materials includes a testing device body, which includes a support frame 1. A shell 2 is mounted above the support frame 1, and a conveying mechanism 3 is mounted on the rear side of the shell 2. The conveying mechanism 3 can transport batches of workpieces to be tested from the outside toward the testing position to ensure the smooth progress of subsequent testing and replace manual feeding. A partition mechanism 4 is mounted at the tail end of the conveying mechanism 3. The partition mechanism 4 can facilitate the loading of externally transported workpieces to be tested, especially to achieve intermittent loading of materials, replacing manual labor and saving labor and time costs, thus meeting the usage requirements. A picking and placing mechanism 5 is mounted on one side of the partition mechanism 4. The picking and placing mechanism 5 can transport the transported materials toward the testing position and can also transport materials at multiple workstations to ensure the smooth progress of testing at each processing point. To enhance practicality, a tensile testing mechanism is installed inside the housing 2 on both sides of the partition mechanism 4. The tensile testing mechanism includes a drive assembly 6, an installation assembly 7 on one side of the drive assembly 6, and a clamping mechanism 8 that can be adjusted laterally on the front side of the installation assembly 7. The clamping mechanism 8 can adaptably clamp the workpiece and, under the action of the drive assembly 6 and the installation assembly 7, perform a tensile test on the material to achieve the purpose of the device. A pressing mechanism 10 is installed on one side of the clamping mechanism 8, and a pushing mechanism 11 is installed on the housing 2 below the installation assembly 7. A collection box 12 is installed inside the housing 2 below and in front of the pushing mechanism 11. The pushing mechanism 11 can centrally export the material after testing and collect it using the collection box 12 for centralized processing. The whole process has a high degree of automation, reduces labor costs, and meets the usage requirements. In the above process: the established conveying mechanism 3 can transport batches of workpieces to be tested from the outside towards the testing position to ensure the smooth progress of subsequent testing work and replace the manual feeding process. The established partition mechanism 4 can facilitate the loading of workpieces to be tested from the outside, especially to achieve intermittent loading of materials, replacing manual labor and saving labor and time costs, and meeting the usage requirements. The established picking and placing mechanism 5 can transport the conveyed materials towards the testing position on the one hand, and can also transport materials to multiple workstations on the other hand, ensuring the smooth progress of testing work at each processing point and improving practicality. The established clamping mechanism 8 can adaptably clamp the workpieces and drive the assembly. Under the action of component 6 and mounting assembly 7, the material is subjected to tensile testing to achieve the purpose of the device. The established pushing mechanism 11 can centrally export the material after testing and collect it using the collection box 12 for convenient subsequent centralized processing. The whole process has a high degree of automation, reducing labor costs and meeting usage requirements. This device is reasonably designed, simple in structure, easy to process, and integrates tensile testing and strength testing functions, improving the functionality of the device and ensuring the smooth progress of different testing tasks. At the same time, the entire testing process is achieved through the cooperation of mechanical equipment components, improving the automation level of the device, reducing labor costs, reducing labor intensity, fully improving the work process, and effectively meeting usage requirements.

[0021] To facilitate the transport of workpieces to be tested, the conveying mechanism includes a mounting frame 31. A conveyor belt 32 is mounted above the mounting frame 31. Two sets of conveyor belts 32 are arranged side by side and mirror images of the mounting frame 31, extending into the housing 2. Specifically, the two sets of conveyor belts 32 are located near the two sides of the housing 2, with the middle position providing convenient space for the partition mechanism 4. The operation of the conveyor belts 32 is driven by an intermediate drive mechanism. Of course, the specific working method and working principle of this conveying mechanism 3 are readily known to those skilled in the art. In this embodiment, batches of workpieces to be tested can be transported towards the testing position to ensure the smooth progress of subsequent tensile testing and improve the functionality of the device.

[0022] To facilitate the loading of externally transported test workpieces, the partition mechanism 4 includes a mounting plate 41. A lifting screw 42 is located at the geometric center of the mounting plate 41, and a screw nut 421 is located at the connection between the lifting screw 42 and the mounting plate 41. Limit sleeves 43 are provided on both sides of the mounting plate 41, and a lifting rod 44 is provided inside the limit sleeves 43. A lifting plate 45 is provided at the upper end of the lifting screw 42 and the lifting rod 44, and a partition 46 is provided on the lifting plate 45. The partition 46 is designed in an L-shape. Furthermore, the width of its short side is adapted to the gap between two adjacent materials. A support plate 47 is provided at the lower end of the lifting rod 44, and a motor 48 is provided above one side of the support plate 47. A drive wheel 481 is provided at the output end of the motor 48. A driven wheel 49 is provided at the lower end of the lifting screw 42. A synchronous belt 410 is provided on the outer side of the drive wheel 481 and the driven wheel 49. It should be further explained that the partition mechanism 4 established in this embodiment has the function of partitioning materials. That is, when in use, the motor 48 is controlled to run, and the drive wheel 481 at its output end rotates. The driving force is transmitted through the synchronous belt 410 to the driven wheel 49. When the driven wheel 49 rotates, it drives the lifting screw 42, which can move vertically and rotate relative to the screw nut 421 on the mounting plate 41. In particular, it can drive the support plate 47 to move upward, so as to separate two adjacent materials to be tested. That is, when it rises, the upper end face of the lifting plate 45 is flush with the upper end face of the conveying mechanism 3, and the partition plate 46 will extend, so that the material that comes first can continue to be conveyed by the conveying mechanism 3 toward the pick-and-place machine. The material is conveyed at the clamping mechanism 13 in the middle of structure 5, and then the clamping mechanism 13 is used to clamp the material, which provides convenient conditions for subsequent conveying to the clamping mechanism 8, greatly improving the convenience of the feeding process. After the material is conveyed first, the partition mechanism 4 descends, and then another material is conveyed forward a certain distance. Then the partition mechanism 4 is used to partition the subsequent workpieces, and the material in the first place is in a waiting state. This process is repeated, which can realize the intermittent feeding of materials, and can also replace manual labor to save manpower and time costs, thus meeting the usage requirements.

[0023] To ensure the smooth conduct of the tensile test, the drive assembly 6 includes a horizontal plate 61, with a stand 62 positioned on one side above the horizontal plate 61. A motor 63 is located behind the stand 62, and a drive disc 64 is located at the output end of the motor 63. The drive disc 64 has a connection hole 641. The mounting assembly 7 includes an I-shaped frame 71 with a transverse sliding assembly 72. The transverse sliding assembly 72 typically includes a slide rail and a slide block assembly as in the prior art to ensure smooth movement. A transverse sliding plate 73 is mounted on the transverse sliding assembly 72, and a connecting rod 74 is located on one side of the transverse sliding plate 73. One end of the connecting rod 74 is connected to the connection hole 641. Specifically, for the drive assembly 6, the operation of the motor 63 provides driving power to the drive disc 64, causing it to move smoothly. When rotation occurs, the transverse slide plate 73 can be moved and adjusted relative to the I-beam 71 in the transverse direction for the installed assembly 7. In particular, for the installed connecting rod 74, when the drive disc 64 in the drive assembly 6 has driving power due to rotation, it can act on the transverse slide plate 73 of the installed assembly 7 through the connecting rod 74, that is, the transverse slide plate 73 has a tendency to move laterally, and can drive the clamping mechanism 8 to move, so that the clamping mechanism 8 can perform tensile testing, ensuring the smooth progress of the testing work. Of course, for the process of performing tensile testing in the transverse direction to achieve tensile force detection, its specific working method can refer to the horizontal tensile testing machine. The specific working principle can be known by those skilled in the art. This embodiment aims to solve the automation level of the entire testing process, so as to reduce labor intensity and workload.

[0024] To facilitate the clamping of the workpiece to be tested and ensure the smooth conduct of the tensile test, the clamping mechanism 8 includes an L-shaped seat 81 connected to the transverse slide plate 73. One side of the L-shaped seat 81 has a mounting ear 82, and a drive rod 83 is positioned between the two mounting ears 82. One side of the mounting ear 82 has a mounting base 84, within which a driven rod 86 and a drive rod 85 are arranged vertically. One side of the drive rod 85 has a drive gear 851, and one side of the driven rod 86 has a driven gear 861. The drive gear 851 and the drive gear 851... Gears 851 mesh, and the driving gear 851 and the driving rod 85 rotate synchronously relative to the mounting base 84. The driven rod 86 does the same, and the two can rotate synchronously in opposite directions to ensure the clamping action. The outer side of the drive rod 83 has a tooth groove 831 that meshes with the driving gear 851. For the drive rod 83 in this embodiment, it uses lifting to drive the driving gear 851. That is, a cylinder is set above the L-shaped base 81, and the extension and retraction of the cylinder provides driving power to the drive rod 83. When the drive rod 83 rises and falls, the tooth groove 831 meshes with the drive gear 851, providing driving power for clamping the material. Alternatively, the connection between the drive rod 83 and the cylinder can be replaced with a worm gear and motor 48. Similarly, the driving power is applied to the drive gear 851, and the meshing causes the driven gear 861 to rotate, providing driving power for the rotating plate 87. A rotating plate 87 is provided on the other side of both the drive rod 85 and the driven rod 86. A self-adaptive clamping assembly 9 is provided on the rotating plate 87, specifically described as: utilizing... The established material handling mechanism 5 transports the workpiece to be tested on the conveying mechanism 3 upward to a suitable position, controls the movement of the drive rod 83, causing the drive gear 851 to rotate, which in turn drives the driven gear 861 to rotate, thereby causing the drive rod 85 and the driven rod 86 to rotate together and act on the rotating plate 87. Of course, the rotating plate 87 also rotates with the drive rod 85 and the driven rod 86 respectively. In this way, the self-adaptive clamping assembly 9 can approach the two ends of the workpiece in a rotating manner to complete the clamping, providing convenient conditions for subsequent tensile testing.

[0025] In order to further improve the rationality of the device and equipment, especially to ensure the clamping effect of the workpiece during the tensile test and reduce the possibility of damage at the clamping position, the self-adaptive clamping component 9 includes a connecting rod 91. On the outer side of the connecting rod 91, there is a placement plate 92 designed in a Chinese character shape. At the corner of the middle position of the placement plate 92, there is a damping telescopic rod 93. For the established damping telescopic rod 93, a spring is established at the bottom side of its interior. When the clamping plate 95 inclines towards the end edge of the placement plate 92 near one limit rod 97, the damping telescopic rod 93 near this limit rod 97 is compressed and has a pushing force. The other two damping telescopic rods 93 will also elongate due to the expansion and contraction of the springs in their interiors in the compressed state. The maximum elongation distance is adapted to the maximum inclination state of the clamping plate 95 under the spherical joint 94. When the self-adaptive clamping component 9 changes from the inclined state to the horizontal state, the compressed spring returns to its original state, waiting for the next clamping of the material. Below the connecting rod 91, there is a spherical joint 94. Below the spherical joint 94, there is a clamping plate 95. The spherical joint 94 can achieve omnidirectional rotation adjustment. Its upper end is connected to the connecting rod 91, and the lower end is connected to the bottom of the clamping plate 95, enabling the clamping plate 95 to achieve multi-directional inclination adjustment relative to the connecting rod 91. On the clamping plate 95 below the damping telescopic rod 93, there is a protective sleeve 951. At the corners of the clamping plate 95, there are suction cups 96. On both sides of the placement plate 92, there are limit rods 97. Specifically described as follows: For the established self-adaptive clamping component 9, the limit rods 97 on both sides are on the same horizontal plane as the rotating plate 87. In the static state, restricted by the establishment of the damping telescopic rod 93, the clamping plate 95 is in a planar state. Subsequently, the clamping mechanism 8 is controlled to operate, enabling the self-adaptive clamping component 9 to contact the outer surface of the workpiece. First, the suction cups 96 act on the workpiece to complete the preliminary clamping. During use, on the one hand, after the power received by the driving rod 83 acts on the workpiece through the rotating frame, stable clamping of the workpiece can be achieved. On the other hand, for the end face conditions of different workpieces, the self-adaptive clamping component 9 can be adaptively fitted to the workpiece, ensuring the smooth realization of the clamping work. At the same time, this design can reduce the possibility of damage to the workpiece, providing convenience for the subsequent strength detection work, ensuring the accuracy of the detection, and meeting the use requirements.

[0026] To facilitate the pressure strength testing of workpieces after tensile testing, the pressing mechanism 10 includes a stable seat 101 connected to a transverse slide plate 73. A screw lifting assembly 102 is positioned above one side of the stable seat 101. Above the screw lifting assembly 102, a device component such as a motor 48 is also provided to provide driving power. An adjustable plate 103, which can be raised and lowered, is positioned on the outer side of the screw lifting assembly 102. The rear side of the adjustable plate 103 slides vertically relative to the transverse slide plate 73. A pressure block 104 is positioned below the adjustable plate 103. A receiving plate 105 is positioned on the horizontal plate 61 below the pressure block 104. Specifically, for the screw lifting assembly 102, the screw component itself... When the driving power is applied, the plate rotates and applies the driving power to the adjusting plate 103, causing it to move vertically up and down relative to the transverse sliding plate 73. This, in turn, causes the pressure block 104 to move vertically up and down. When pressure strength testing is performed, the pressure block 104 is moved down and acts on the workpiece. A pressure sensor can be installed in the receiving plate 105 to detect the pressure on the workpiece during the pressing process, facilitating the recording of test data. Once the workpiece is cracked by the pressing component or reaches the required pressure strength test standard, the control screw lifting component 102 is reset, ready for the next testing and processing operation. At the same time, it also ensures that workpieces that have completed the strength test are collected and exported to avoid motion interference and improve functionality.

[0027] To facilitate convenient adjustment of the position of the material being tested, the material handling mechanism 5 includes a key-shaped concave lifting seat 51. A first vertical sliding component 52 is located on the front side of the lifting seat 51, and a second vertical sliding component 53 is located on the rear side. A vertical sliding plate 54 is located on one side of the first vertical sliding component 52, and a clamping mechanism 13 is mounted on the vertical sliding plate 54. A vertical rack 55 is located on the other side of the vertical sliding plate 54. A stepper motor 56 is located on one side of the lifting seat 51, and a drive gear 561 is mounted on the drive end of the stepper motor 56, meshing with the vertical rack 55. A transverse extension component 14 is located above the lifting seat 51. Two sets of transverse extension components 14 are arranged symmetrically above and below each other. Each transverse extension component 14 includes a first sliding bar. 141. A first slide block 142 is provided on the first slide bar 141. A second slide bar 143 is provided on one side of the first slide block 142. A second slide block 144 is provided on the second slide bar 143. A connecting plate 145 is provided on the second slide block 144. An L-shaped opening and closing plate 146 is provided on the outer side of the connecting plate 145. The two opening and closing plates 146 are staggered. Specifically, when the two opening and closing plates 146 are in the middle position, one opening and closing plate 146 is placed inside the other opening and closing plate 146 to prevent movement interference. When the two opening and closing plates 146 are in the middle position, the left and right clamping mechanisms 13 and the clamping mechanism 8 are close to each other, so that the clamping mechanism 13 can clamp the stretched material. After the work is completed, a clamping mechanism 13 is also provided on the outer side of the opening and closing plate 146, and an adjusting rod 147 is provided between the vertical sliding plate 54 and the inner side of the opening and closing plate 146. Specifically, when it is necessary to convey the material at the conveying mechanism 3 toward the clamping mechanism 8, the clamping mechanism 13 is first used to clamp the material, and then the stepper motor 56 is controlled to run, so that the drive gear 561 rotates and acts on the vertical rack 55, so that the vertical sliding plate 54 is adjusted vertically relative to the lifting seat 51. At the same time, when the vertical sliding plate 54 moves upward, the adjusting rod 147 will receive the driving power and act on the opening and closing plate 146, so that the opening and closing plate 146 achieves secondary expansion on the sliding bar and sliding seat, thereby opening and closing the plate. When the hinge plate 146 is unfolded, and the vertical sliding plate 54 moves to its highest position, the clamping mechanism 8 clamps the material. Then, the lifting seat 51 is controlled to move vertically relative to the first vertical sliding assembly 52, allowing the material clamped by the clamping mechanism 13 on the hinge plate 146 to be placed towards the lower position of the pressing mechanism 10. The lifting seat 51 is then controlled to return to its vertical position, waiting for the clamping mechanism 8 to complete the tensile test on the material. Simultaneously, the vertical sliding plate 54 also descends vertically to return to its vertical position, clamping the next workpiece. After the previous material is placed below the pressing mechanism 10, the tensile test on the next material is completed. Once the tensile test is complete, the pressing mechanism 10 is controlled to be positioned above the appropriate position of the workpiece. If the material breaks due to prior tensile testing...If the drive disk 64 fails to reach the farthest position, the drive assembly 6 continues to run to the farthest position, then waits for the pressing mechanism 10 to complete the pressing strength test of the material. Once the strength test is complete, the drive assembly 6 continues to run, driving the clamping mechanism 8 towards the geometric center. At this time, the two clamping mechanisms 13 on the loading and unloading mechanism 5 will clamp the workpiece that has completed the tensile test, and the above process is repeated. This cycle is repeated, thus achieving both the tensile test and the strength test of the material to be tested. Furthermore, the entire process is mechanized, greatly improving the automation level of the equipment, ensuring the work progress, and meeting usage requirements.

[0028] To facilitate convenient gripping of the material to be tested and subsequent adjustment of its position, thereby automating various testing tasks, the clamping mechanism 13 includes a base 131. An extension plate 1311 is provided on the front side of the base 131. A rotating gear 132 is positioned between the two extension plates 1311. A fixed gripper 133 is located above the base 131. A limit strip 1312 is provided on the base 131 below the extension plates 1311. An adjusting gripper 134 is provided on one side of the rotating gear 132. A U-shaped adjusting rack 1341 is located below the adjusting gripper 134 and interacts with the rotating gear. The gears 132 and 132 are engaged. A drive motor 135 is provided on the outer side of the base 131, and its output end is connected to the rotating gear 132. Specifically, during use, the drive motor 135 is controlled to run, and the driving power acts on the rotating gear 132. Through meshing, it acts on the adjusting rack 1341, so that the adjusting jaw 134 can move and adjust relative to the limiting bar 1312 until the fixed jaw 133 and the adjusting jaw 134 can contact the two sides of the workpiece respectively, thereby completing the clamping of the building material. This design can be adapted to workpieces of different sizes, improving the functionality of the device and meeting the usage requirements.

[0029] To facilitate the convenient export of the tested materials, the pushing mechanism 11 includes a pushing cylinder 111. The output end of the pushing cylinder 111 is equipped with a pushing plate 112, which corresponds to the lower part of the pressing mechanism 10. Specifically, after the pressing mechanism 10 completes the strength test of the material, it controls the pressing mechanism 10 to rise and reset. Then, it controls the pushing cylinder 111 to extend and drive the pushing plate 112 to move forward, thereby acting on the building material on the receiving plate 105 and pushing it into the collection box 12 to complete the convenient collection of the material. After all the testing work is completed, the collection box 12 is taken out, and the tested material is processed for subsequent processing. The operation is simple and convenient, and the functionality is strong.
