Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass testing technology, specifically a material strength testing device. Background Technology
[0002] Tempered glass is widely used in construction projects due to its high strength, safety, and aesthetics. However, the strength of tempered glass is directly related to the safety and reliability of buildings, making accurate and efficient strength testing crucial.
[0003] Traditional testing equipment mainly consists of a fixed worktable and a movable pressure head. The glass to be tested is placed on the worktable, and pressure is applied by the press to complete the test. The strength is evaluated by measuring the pressure value that the glass bears. Without effective restraint of the glass, the glass may slide outward during the pressure process, resulting in uneven stress distribution. Due to the sliding of the glass, the actual applied pressure may not accurately reflect the true strength of the material, thus affecting the reliability of the test results. Utility Model Content
[0004] To achieve the above objectives, the present invention provides the following technical solution: a material strength testing device, comprising a rotating worktable mounted on a testing platform, and a feeding assembly and a discharging assembly located around the rotating worktable. The rotating worktable is divided into a rotating disk and a fixed disk. Multiple clamps are mounted on the rotating disk, and two opening and closing assemblies located above two of the clamps are mounted on the fixed disk. A pressure testing assembly located above one of the clamps is mounted on the fixed disk.
[0005] The testing platform is also equipped with a support assembly located below the rotating disk;
[0006] The fixture includes a support plate and side blocks located on both sides of the support plate. The support plate is slidably connected with relatively distributed clamping plates, and a spring connected to the corresponding side block is fixed on one side of the clamping plate.
[0007] The pressure detection assembly includes a pressure frame, a push cylinder is installed on one side of the pressure frame, the piston rod of the push cylinder is fixed to a T-shaped plate that slides on the pressure frame, a limit plate is installed on the T-shaped plate, and a pressure block that is not on the same horizontal line as the limit plate is installed on the limit plate.
[0008] Furthermore, the limiting plate is located above the two clamping plates, and a trapezoidal groove adapted to the two clamping plates is opened at the bottom.
[0009] Furthermore, a sleeve block is fixed to one side of the limiting plate, the pressure block is T-shaped and passes through the sleeve block, and the top of the sleeve block is rotatably connected to an adjusting bolt that is threadedly connected to the T-shaped plate.
[0010] Furthermore, a spring is fitted onto the outer side of the adjusting bolt between the T-shaped plate and the pressure block.
[0011] Furthermore, the support assembly includes a slide table, a push cylinder is installed on one side of the slide table, the piston rod of the push cylinder is fixed with a push plate that slides with the slide table, and an L-shaped support block is fixed on the push plate.
[0012] Furthermore, a stop block is fixed on one side of the slide table, and a lifting block located below the stop block is fixed on one side of the push plate.
[0013] Furthermore, the support assembly also includes a base plate, the slide is slidably connected to the base plate, and a locking block is fixed to the side of the base plate. A bolt is threaded onto the locking block, and one end of the bolt is rotatably connected to the slide.
[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0015] The strength testing device for this material uses clamps to hold and fix the sample glass. Then, the rotating worktable is moved to the bottom of the pressure testing component. When the pressure testing component moves the pressure block to press down on the glass to test the strength, the limiting plate moves down with it, covering the two clamps in the slot and limiting them. This can prevent the glass from sliding during the test, which would cause uneven stress distribution and affect the test results. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This embodiment of a material strength testing device includes a rotary worktable 1 fixed on a testing platform, and a feeding assembly 4, a discharging assembly 5, and a support assembly 6 located around the rotary worktable 1. The rotary worktable 1 is divided into a rotating disk and a fixed disk. The fixed disk is located above the rotating disk and has a smaller diameter than the rotating disk. The driving end of the rotary worktable 1 drives the rotating disk to rotate. The fixed disk extends into the driving end and is fixed, so the fixed disk does not rotate with it. Multiple sets of clamps 2 are installed on the rotating disk. Two sets of opening and closing assemblies 3 are installed on the fixed disk, which are perpendicular and symmetrical to two of the clamps 2. A pressure detection assembly 7 located above one of the clamps 2 is also installed on the fixed disk. The support assembly 6 is located below the pressure detection assembly 7, and its support end can be attached to the bottom of the rotating disk to support it.
[0023] In the above structure, the opening and closing component opens the clamp, the feeding component places the sample glass into the clamp and fixes it, the rotating table drives the rotating disk to rotate, thereby moving the clamp carrying the sample below the pressure detection component, and then the support component moves up to support the rotating disk, while limiting one end of the clamp opening. Then the pressure detection component presses down to complete the strength test of the glass sample. During the pressure test, it also limits the clamp to prevent the test results from being affected by the sliding of the glass.
[0024] like Figure 2 In the aforementioned direction, the clamp 2 includes a support plate 21 fixed on a rotating disk and side blocks 22 fixed on both sides of the support plate 21. Two sets of opposing clamping plates 24 are slidably connected to the support plate 21. A spring 25 connected to the corresponding side block 22 is fixed on the opposite side of the two clamping plates 24. A protrusion and an inner plate are formed on the support plate 21 between the two sets of clamping plates 24. By pressing down on the opening and closing assembly, the clamping plates can be squeezed to move and open, so the feeding assembly can place the product between the two clamping plates. Then, the spring 25 pushes the clamping plates to clamp the glass and complete the clamping and fixing.
[0025] like Figure 4In the indicated direction, the support assembly 6 includes a base plate 61 fixed to the testing table. A locking block 62 is fixed to the front of the base plate 61, and a slide 63 slides on the top. A bolt 64 is threaded onto the locking block 62 and rotates with the front of the slide 63. A push cylinder 66 is installed on the left side of the slide 63. A push plate 67 that slides with the slide 63 is fixed to the piston rod of the push cylinder 66. A support block 68 is fixed to the left side of the push plate 67. A protrusion is formed on the left side of the support block 68. A lifting block 610 is fixed to the left side of the push plate 67. A stop block 69 located above the lifting block 610 is fixed to the back of the slide 63.
[0026] By tightening the bolts, the slide can be finely adjusted, allowing the support block to be precisely positioned. Then, the push cylinder moves the push plate upward, causing the protrusion of the support block to support the rotating disk. At the same time, the support block also blocks the gap between the two sets of clamping plates, acting as a limit. During the movement of the push plate, the stop block limits the lifting block, ensuring that the support block stops precisely in the designated position, thus completing the functions of support and limitation.
[0027] like Figure 3 In the indicated direction, the pressure detection assembly 7 includes a pressure frame 71 fixed on a fixed plate. A push cylinder 72 is installed on the left side of the pressure frame 71. The piston rod of the push cylinder 72 is fixed with a T-shaped plate 73 that slides with the pressure frame 71. A limit plate 75 is fixed on the right side of the T-shaped plate 73. A trapezoidal slot is opened at the bottom of the limit plate 75. A sleeve block 76 is also fixed on the right side of the limit plate 75. A T-shaped pressure block 77 is inserted through the sleeve block 76. The width of the pressure block 77 is smaller than the width of the trapezoidal slot. An adjusting bolt 78 that is threadedly connected to the top of the pressure block 77 is rotatably connected to the T-shaped plate 73. A spring 79 located between the pressure block 77 and the T-shaped plate 73 is sleeved on the outside of the adjusting bolt 78. First, by turning the adjusting bolt, the pressure block can be raised and lowered until the concave block is adjusted to the appropriate height. The elasticity of the second spring can also improve the locking effect of the adjusting bolt, pushing the cylinder to move the T-shaped plate down, thereby enabling the pressure block to press down on the glass for testing. At the same time, the limiting plate will cover the two sets of clamping plates in the groove to limit them, preventing the clamping plates from moving left and right and affecting the subsequent pressure test of the glass.
[0028] Therefore, during the pressure test, the limiting block can limit the clamping plate. Because the bottom of the limiting block is a ladder-shaped groove, the further the limiting block moves downward, the more stable the clamping plate is. At the same time, in conjunction with the inner plate and support block in the fixture, the glass can be limited on all four sides to avoid sliding and displacement during the pressure process, which would affect the results of subsequent tests.
[0029] The working principle of the above embodiments is as follows:
[0030] First, the opening and closing assembly presses down to push the two clamping plates apart. The feeding assembly places the glass between the clamping plates. The opening and closing assembly retracts, and the spring force pushes the clamping plates to clamp and fix the glass. The rotating worktable rotates, causing the pressure block to move downwards. The push cylinder moves upwards, and the support block supports the rotating disk and extends to the top to block the gap between the clamping plates. The inner plate, in conjunction with the support, can limit the glass on all four sides. Then, the cylinder moves downwards, and the concave surface of the limiting plate covers the two clamping plates inside, which can limit the movement of the clamping plates and prevent the glass from moving along with them, affecting the test. Finally, the pressure provided by the pressure block is used to determine the strength of the glass.
[0031] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
