Description

Technical Field

[0001] The present invention relates to the technical field of glass impact resistance testing, and particularly to a multi-directional stress glass impact resistance testing device based on hydraulic servo loading. Background Art

[0002] A glass impact resistance testing device is a device specifically used to evaluate the anti-extrusion impact ability of glass products. Its working principle is mainly to simulate various impact situations that may occur in actual use and conduct impact tests on glass products.

[0003] After retrieval, a Chinese patent with the publication number CN218412103U discloses a glass impact resistance testing device, including a test base and a support rod installed on the back of the test base; a chute is provided at the top of the support rod, and a moving plate is slidably arranged in the chute; a sunken placement cavity is formed in the center of the test base, and a steel ball adsorption component is installed below the moving plate, and the position of the steel ball adsorption component corresponds to the central position of the placement cavity. The above scheme is convenient for detecting the damage suffered by tempered glass, laminated glass, and insulating glass under different impact forces, and does not require manual throwing, which is convenient for operation. However, when the above scheme is actually used, there are still the following deficiencies:

[0004] The glass impact testing device proposed by the above scheme can only perform free-fall impact tests and cannot perform pendulum impact tests. Its functional singularity brings significant drawbacks, mainly reflected in the inability to comprehensively simulate and evaluate the diverse impact scenarios that glass may encounter in actual use. Since different impact forms result in different stress distributions and failure modes on glass, the lack of pendulum impact test capabilities means it is difficult to accurately predict the impact resistance of glass under complex conditions such as direct impact of objects and dynamic load effects. This not only limits the comprehensiveness and accuracy of test results but may also reduce the reliability of products in specific application scenarios due to the failure to detect potential safety hazards in a timely manner.

[0005] Therefore, it is necessary to design a multi-directional stress glass impact resistance testing device based on hydraulic servo loading to solve the above problems. Summary of the Invention

[0021] The present invention has the following beneficial effects:

[0022] 1. The glass impact resistance test device proposed by the present invention integrates two test functions of drop impact and pendulum impact, achieving a comprehensive coverage of various impact types of glass. Its significant advantage is that it can use multi-dimensional test data for cross-verification, greatly improving the accuracy and reliability of the impact resistance performance evaluation, and at the same time broadening the applicable scenarios of the test results;

[0023] 2. The connection and separation between the impact block and the rotating seat are realized through the connecting assembly. The advantage is that the staff only needs to simply pull the plug rod to move the plug rod out of the channel, and then the connecting block can be inserted into the channel to complete the assembly. When the connecting block is in place and the slot is aligned with the socket, release the plug rod, and the plug rod automatically inserts into the slot under the action of the return spring to fix the connecting block. This design greatly simplifies the connection and separation operations of the impact block and the rotating seat, improving the work efficiency and convenience;

[0024] 3. In the pendulum impact test, by designing a device that can adjust the number of counterweight plates, the staff can easily change the impact force exerted by the impact block on the glass. This device allows the staff to retract the pressing plate into the through-hole by pinching the pushing block, so as to smoothly insert or remove the counterweight plate. After the counterweight plate is assembled in place, release the pushing block, and the pressing plate will reset under the action of the spring and fix the counterweight plate. This design greatly simplifies the adjustment process of the counterweight plate, improves the operation efficiency, enables the staff to quickly and accurately adjust the impact force to meet different test requirements, and further enhances the flexibility and accuracy of the pendulum impact test.

[0025] 4. The rotatable cover plate provided on the impact block is connected to the torsion spring through a hinge and always has a tendency to cover the impact block, forming a spherical structure. When the staff releases the cover plate, the cover plate will automatically reset. The advantage of this design is that the cover plate can effectively ensure the stability of the overall structure of the impact block and the counterweight plate on it, prevent the counterweight plate from falling off during the impact test, and thus ensure the accuracy and safety of the test.

[0040] Referring to Figures 1-12 , a multi-directional stress glass impact resistance testing device based on hydraulic servo loading includes a frame 1, a hydraulic push rod 2 is installed on the frame 1, a lifting frame 3 is slidably arranged on the frame 1, the telescopic end of the hydraulic push rod 2 is connected to the lifting frame 3, a first glass clamp 4 and a second glass clamp 5 are installed on the frame 1, the first glass clamp 4 is arranged horizontally, the second glass clamp 5 is arranged vertically.

The staff can flexibly select the drop impact testing function to simulate the scenario of glass free fall, or use the pendulum impact testing function to accurately reproduce the dynamic process of object impact. Compared with traditional single-function testing devices, its significant advantage is that it can comprehensively cover various impact types that glass may encounter in actual applications. Through cross-verification of multi-dimensional test data, it not only greatly improves the accuracy and reliability of the impact resistance performance evaluation, but also effectively expands the applicable scenario range of the test results, providing strong technical support for the quality control, safety performance optimization and application field expansion of glass products;

[0041] A swing unit is provided on the lifting frame 3. The swing unit consists of a swing component and a locking component. The swing component includes a fixed frame 61 and a swing rod 63. The fixed frame 61 is fixed on the side of the lifting frame 3. A fixed shaft 62 is fixed at one end of the fixed frame 61 close to the lifting frame 3. One end of the swing rod 63 is rotatably connected to the fixed shaft 62. The locking component is arranged on the fixed frame 61 and is used to provide a limit for the swing rod 63. The locking component includes an opening 64, a fixed block 65, a guide sleeve 66 and a positioning rod 67. The opening 64 is opened on the top surface of the fixed frame 61. The fixed block 65 is fixed on the swing rod 63 and extends into the opening 64. A hole is opened on the fixed block 65. The guide sleeve 66 is fixed on the top surface of the fixed frame 61. The positioning rod 67 is movably inserted into the guide sleeve 66, and one end of the positioning rod 67 extends into the hole. The positioning rod 67 and the guide sleeve 66 are connected by a tension spring 68. The staff pulls the positioning rod 67 to disengage it from the hole. Without the positioning function of the positioning rod 67, the swing rod 63 and the impact block 81 will swing under the action of gravity, so that the swing rod 63 and the impact block 81 rotate around the fixed rod, enabling the impact block 81 to impact the glass in a swinging posture, and thus realizing the pendulum impact test on the glass;

[0042] An impact unit is provided at one end of the fixed frame away from the lifting frame 3. The impact unit includes an impact block 81. The impact unit also includes a plurality of slots 83 and a plurality of counterweight components. The plurality of slots 83 are all opened on the impact block 81. The plurality of counterweight components are respectively arranged in the plurality of slots 83. A cover plate 82 is rotatably installed on the impact block 81, and the cover plate 82 and the impact block 81 are connected by a hinge. A torsion spring is arranged on the hinge. The impact block 81 and the cover plate 82 together form a spherical structure. The counterweight component includes a counterweight plate 84, an installation groove 85, two through openings 86, two sliding plates 87 and two pressing plates 88. The counterweight plate 84 is inserted into the slot 83. The installation groove 85 is opened on the side of the counterweight plate 84. The two through openings 86 are respectively opened on both sides of the counterweight plate 84, and both of the two through openings 86 are communicated with the installation groove 85. The two sliding plates 87 are both slidably arranged in the installation groove 85. The two sliding plates 87 are connected by two connecting springs 89. The two pressing plates 88 are respectively fixed on the two sliding plates 87 and respectively slide in the two through openings 86. One end of each of the two sliding plates 87 is fixed with a push block 810. The two push rods are both located outside the installation groove 85. The side surface of the counterweight block is in mutual fit with the groove wall of the slot 83. The staff can change the impact force applied by the impact block 81 on the glass by adjusting the number of the counterweight plates 84;

[0043] An adjustment assembly is provided at the end position of the swing rod 63. The adjustment assembly includes a rotating seat 72. The adjustment assembly further includes a mounting rod 71, a fixed ear 73, a limit pin 74, and a limit rod 75. The mounting rod 71 is fixed to the end of the swing rod 63 away from the fixed shaft 62. The rotating seat 72 is rotatably mounted on the mounting rod 71. A channel is provided on the side surface of the rotating seat 72. The fixed ear 73 is fixed to the side surface of the rotating seat 72, and two through holes are provided on the fixed ear 73. The limit pin 74 is inserted into the two through holes. The limit rod 75 is fixed to the mounting rod 71, and a through opening 76 is provided on the limit rod 75. First, the staff pulls out the limit pin 74 from the fixed ear 73, and then rotates the impact block 81 to drive the rotating seat 72 to rotate until the rotating seat 72 rotates 90°. When the rotating seat 72 rotates 90°, the two through holes on the fixed ear 73 are exactly aligned with the through opening 76 on the limit rod 75. At this time, the staff inserts the limit pin 74 into the two through holes and the through opening 76 to fix the position of the fixed ear 73. When the fixed ear 73 is fixed, the positions of the rotating seat 72 and the impact block 81 are fixed accordingly;

[0044] The impact block 81 and the rotating seat 72 are connected by a connecting assembly. The adjustment assembly is used to adjust the angle of the impact block 81. The connecting assembly includes a connecting block 91, a socket 92, a plug rod 93, and a slot 95. The connecting block 91 is fixed to the impact block 81. The shape of the connecting block 91 is adapted to the shape of the channel. The slot 95 is provided on the side surface of the connecting block 91. The socket 92 is provided on the side surface of the rotating seat 72, and the socket 92 is communicated with the channel. The plug rod 93 is movably inserted into the socket 92. The plug rod 93 and the rotating seat 72 are connected by a return spring 94. For the impact block 81 and the rotating seat 72, the two are connected by a connecting assembly. When connecting the impact block 81 and the rotating seat 72, the staff first pulls the plug rod 93 to move the plug rod 93 out of the channel, and then inserts the connecting block 91 into the channel. When the connecting block 91 is assembled in place, the slot 95 on the connecting block 91 is exactly aligned with the socket 92. At this time, the staff releases the plug rod 93 to make the plug rod 93 reset under the elastic force of the return spring 94. When the plug rod 93 resets, it can be inserted into the slot 95 and fix the connecting block 91. Through this design, the rapid connection and separation of the impact block 81 and the rotating seat 72 are realized.

[0045] The specific working principle of the present invention is as follows:

[0046] The glass impact resistance testing device proposed by the present invention integrates the functions of drop impact testing and pendulum impact testing. Staff can flexibly select the drop impact testing function to simulate the scenario of glass free fall, or use the pendulum impact testing function to accurately reproduce the dynamic process of object impact. Compared with traditional single-function testing devices, its significant advantage is that it can comprehensively cover the diverse impact types that glass may encounter in actual applications. Through cross-verification of multi-dimensional test data, it not only greatly improves the accuracy and reliability of impact resistance performance evaluation, but also effectively expands the applicable scenario range of test results, providing strong technical support for the quality control, safety performance optimization and application field expansion of glass products;

[0047] For the drop impact testing function, the staff clamps the glass to be tested on the first glass fixture 4. At this time, the impact block 81 is located directly above the glass. When conducting the test, the staff first pulls the insertion rod 93 to move the insertion rod 93 until it disengages from the slot 95. Without the restriction of the insertion rod 93, the connecting block 91 can disengage from the channel. Under the action of gravity, the impact block 81 will fall downward and land on the glass, enabling the drop impact test of the glass. When it is necessary to change the impact force exerted by the impact block 81 on the glass, the staff can activate the hydraulic push rod 2 to drive the lifting frame 3 to move upward. When the lifting frame 3 moves upward, it can drive the fixed frame to move, and the impact block 81 moves upward accordingly. When the falling stroke of the impact block 81 increases, the impact force exerted by the impact block 81 on the glass increases. Therefore, the staff can adjust the height of the impact block 81 through the hydraulic push rod 2, thereby adjusting the impact force exerted by the impact block 81 on the glass;

[0048] For the impact block 81 and the rotating seat 72, they are connected by a connecting component. When connecting the impact block 81 and the rotating seat 72, the staff first pulls the insertion rod 93 to move it out of the channel, and then inserts the connecting block 91 into the channel. When the connecting block 91 is assembled in place, the slot 95 on the connecting block 91 is exactly aligned with the socket 92. At this time, the staff releases the insertion rod 93, and the insertion rod 93 is reset under the elastic force of the return spring 94. When the insertion rod 93 is reset, it can insert into the slot 95 and fix the connecting block 91. Through this design, the rapid connection and separation of the impact block 81 and the rotating seat 72 are realized;

[0049] Such as Figure 8As shown, for the pendulum impact test, the staff clamps the glass to be tested onto the second glass fixture 5, and then adjusts the position of the impact block 81 through the adjustment component. Specifically, the staff first pulls out the limit pin 74 from the fixed ear 73, and then rotates the impact block 81 to drive the rotating seat 72 to rotate until the rotating seat 72 rotates 90°. When the rotating seat 72 rotates 90°, the two through holes on the fixed ear 73 are exactly aligned with the through openings 76 on the limit rod 75. At this time, the staff inserts the limit pin 74 into the two through holes and the through openings 76 to fix the position of the fixed ear 73. When the fixed ear 73 is fixed, the positions of the rotating seat 72 and the impact block 81 are fixed accordingly. Further, the staff pulls the positioning rod 67 to disengage it from the hole position. Without the positioning function of the positioning rod 67, the swing rod 63 and the impact block 81 will swing under the action of gravity, causing the swing rod 63 and the impact block 81 to rotate around the fixed rod, so that the impact block 81 can impact the glass in a swinging posture, and the pendulum impact test of the glass can be realized;

[0050] During the pendulum impact test, the staff can change the impact force exerted by the impact block 81 on the glass by adjusting the number of counterweight plates 84. Specifically, when increasing the counterweight plates 84, the staff first pinches the two push blocks 810, causing the two push blocks 810 to drive the two sliding plates 87 to approach each other. When the two sliding plates 87 approach each other, the two pressing plates 88 approach each other accordingly and retract into the two through openings 86 respectively. Further, the staff keeps the two pressing plates 88 in the state of approaching each other and inserts the counterweight plate 84 into the slot 83. Since the two pressing plates 88 are respectively located in the two through openings 86, the two pressing plates 88 will not hinder the smooth insertion of the counterweight plate 84 into the slot 83. When the counterweight plate 84 is assembled in place, the staff releases the two push blocks 810, causing the two sliding plates 87 to reset under the elastic force of the two connecting springs 89. When the two sliding plates 87 reset, the two sliding plates 87 and the two pressing plates 88 will move away from each other until the two pressing plates 88 jointly press against the slot wall of the slot 83. At this time, the two pressing plates 88 play a role in fixing the counterweight plate 84, and the counterweight plate 84 can be fixed in the slot 83. Through this design, it is convenient for the staff to quickly adjust the number of counterweight plates 84, and thus adjust the impact force exerted by the impact block 81 on the glass;

[0051] It should be noted that a rotatable cover plate 82 is provided on the impact block 81. The cover plate 82 is connected to the impact block 81 through a hinge, and a torsion spring is provided on the hinge. Under the action of the torsion spring, the cover plate 82 always has a tendency to cover the impact block 81. When the cover plate 82 covers the impact block 81, the cover plate 82 and the impact block 81 together form a spherical structure. When the staff releases the cover plate 82, the cover plate 82 will automatically reset under the elastic force of the torsion spring. By providing the cover plate 82, the stability of the overall structure of the impact block 81 and several counterweight plates 84 thereon can be ensured, and the situation of the counterweight plates 84 falling off when the impact block 81 impacts the glass can be avoided.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
