Description

Technical Field

[0001] This invention relates to the field of pressure resistance testing technology in glass-ceramic processing, specifically to a shielded and protective pressure resistance testing machine for glass-ceramic processing. Background Technology

[0002] Microcrystalline glass is one of many new materials. Due to its advantages such as high light transmittance, high hardness and high toughness, microcrystalline glass has well demonstrated the performance advantages of new materials. Therefore, it is widely used in fields such as cameras, mobile phone cover plates, tablets and automotive glass. After the production and processing of microcrystalline glass, a pressure resistance testing machine is also needed to test the pressure resistance performance of microcrystalline glass, so as to determine whether the production of microcrystalline glass is qualified.

[0003] The prior art patent with publication number "CN113075063B" entitled "A Comparative Impact Test Device for Glass" involves placing a complete glass piece inside a support block, with its four corners secured within the block. After adjusting the height of the platform and the iron ball, the lever is manually pulled, causing the guide element to rotate via the transmission shaft, closing the baffle inward. The stopper passes through the support column, compressing the spring. Once adjusted to the appropriate position, the pin is inserted into the through hole on the upper support column. Under the action of the spring, the stopper securely holds the platform in place, completing the positioning. The servo motor is then activated, and the iron ball falls downward, striking the complete glass piece. The shattered glass fragments fall into the collection box. After the test is completed, users pull the handle to remove the collection box and properly collect the glass fragments, achieving both user safety and convenient glass fragment collection.

[0004] 1. The pressure resistance tester described above tests the pressure resistance of glass by starting a servo motor and dropping an iron ball downwards to strike the intact glass. If it is necessary to adjust the impact force of the iron ball falling downwards, in addition to changing to iron balls of different sizes, the only way to adjust the impact force of the iron ball falling downwards is to adjust the height of the iron ball. Each time, it is also necessary to use a ruler to measure the placement height of the iron ball. Therefore, it is not convenient to adjust the impact force of the iron ball falling downwards.

[0005] The prior art patent with publication number "CN116448581B" is entitled "A Test Device for the Pressure Resistance Strength of RV Glass". It is connected to a connecting gear via a rotating shaft. When the first connecting rack pushes the connecting gear to rotate, the main bevel gear disk and the secondary bevel gear disk can be driven to rotate through the connection of the rotating shaft. The secondary bevel gear disk drives the rotating rod to rotate, and the rotating rod drives the protective door to flip. Therefore, when the glass is transported to the bottom of the protective mechanism, the protective door can be driven to flip and fit against the frame at the same time. In this way, during the glass impact, the protective door blocks the debris and prevents the debris from splashing out of the frame and causing danger to the staff. When the glass is moved out of the bottom of the protective mechanism, the protective door resets. The dust removal mechanism, the squeezing mechanism and the protective mechanism are all driven by the regulating cylinder, which reduces the number of power sources. The protective door makes it convenient for the staff to change the impact head of different weights. When the protective door resets, it can be changed. The transparent observation window allows the staff to observe the situation when the glass is impacted.

[0006] 2. Although the protective door installed in the pressure testing machine mentioned above can block debris and prevent it from splashing out of the frame, the debris will have a certain impact force on the inner wall of the frame and the inner wall of the protective door, resulting in a lot of noise. Therefore, it cannot provide good shielding and protection. Moreover, since the protective frame formed by the protective door and the frame has a large area, the debris will be scattered randomly in various positions within the protective frame formed by the protective door and the frame, which is not convenient for subsequent collection. Summary of the Invention

[0007] The purpose of this invention is to provide a shielded and protective pressure testing machine for microcrystalline glass processing, in order to solve the problems mentioned in the background art. Currently, the impact force of an iron ball falling downwards can only be adjusted by adjusting the height of the iron ball. Each time, a ruler is needed to measure the placement height of the iron ball, which is inconvenient for adjusting the impact force of the iron ball falling downwards. Debris will have a certain impact force on the inner wall of the frame and the inner wall of the protective door, resulting in a large noise. Therefore, it cannot provide good shielding and protection. Moreover, since the area of ​​the protective frame formed by the protective door and the frame is large, debris will be scattered randomly in various positions within the protective frame, which is inconvenient for subsequent collection.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a shielded and protective pressure testing machine for microcrystalline glass processing, comprising a worktable and a support frame with an inverted "L" shape structure installed on the rear side above the worktable;

[0009] A rotating rod is rotatably mounted on the support frame, and a lifting rope is wound around the outside of the rotating rod. The rear end of the rotating rod is connected to an external motor.

[0010] The lower end of the lifting rope passes through the upper surface of the support frame and connects to the middle of the upper surface of the iron ball assembly;

[0011] A force adjustment rod is provided on the upper right side of the iron ball assembly. The rear end of the force adjustment rod passes through the rear side of the rotatable connection support frame. An inclined force application plate is installed on the left side of the force adjustment rod. The iron ball assembly is located below the force application plate.

[0012] The upper surface of the workbench is provided with a ring-shaped receiving groove, and a support ring plate is slidably connected inside the receiving groove.

[0013] A protective cover made of umbrella fabric is installed above the support ring plate, and a sponge layer is pasted on the inner wall of the protective cover.

[0014] A ring of fixed rods is installed above the support ring plate, and the inner side wall of the fixed rods is connected to the outer side of the shielding cover.

[0015] An automatic lifting control assembly is installed below the support ring plate.

[0016] Preferably, a manual telescopic rod is installed on the upper front side of the iron ball assembly, and the upper end of the manual telescopic rod is connected to the support frame.

[0017] Furthermore, the manual telescopic rod described above ensures that the iron ball assembly can fall vertically downwards stably, thus facilitating pressure resistance testing of the iron ball assembly.

[0018] Preferably, the lowest point of the force-applying plate is higher than the highest point of the iron ball assembly, the lowest point of the force adjustment rod is lower than the highest point of the iron ball assembly, the rotation speed of the force-applying plate is greater than the free fall speed of the iron ball assembly, and a distance sensor is installed on the upper surface of the iron ball assembly.

[0019] Furthermore, by setting the lowest point of the force plate higher than the highest point of the iron ball assembly, the force plate can apply a downward thrust to the iron ball assembly when it rotates, which facilitates increasing the falling speed of the iron ball assembly and thus increasing the downward impact force of the iron ball assembly.

[0020] Preferably, a threaded rod is rotatably installed in the slotted workbench on the rear side of the receiving groove, and a limit rod is installed in the slotted workbench on the front side of the receiving groove. A first spiral spring is nested and connected to the outer side of the bottom end of the threaded rod.

[0021] Furthermore, the slots in the worktable facilitate the placement of the threaded rod and the limiting rod. At the same time, the slots in the worktable can also limit the push rod, so that the push rod can move up and down stably.

[0022] Preferably, the lifting automatic control assembly includes two push rods with an "L" shape structure symmetrically installed below the support ring plate, and the push rods on the lower rear side of the support ring plate have a threaded rod connected through them;

[0023] Furthermore, the rotating shaft of the threaded rod can drive the push rod connected to the outer thread to rise.

[0024] The push rod on the lower front side of the support ring plate has a sliding connection to a limit rod.

[0025] Preferably, the support ring plate forms a lifting structure with the worktable via a push rod.

[0026] Furthermore, the support ring plate can drive the protective shield to rise steadily.

[0027] Preferably, the lower end of the control rope is wound around the upper outer side of the threaded rod, and the upper end of the control rope passes through the interior of the workbench and support frame and is connected to the upper part of the iron ball assembly through a guide wheel.

[0028] Furthermore, the control rope can automatically drive the threaded rod to rotate, eliminating the need for an external power source.

[0029] Preferably, a movable shaft is rotatably mounted on the upper surface of the support ring plate with a slot, a second magnet block is fixed through the outer side of the movable shaft, a second spiral spring is nested and connected to the outer side of the other end of the movable shaft, and a fixed rod is fixed above the second magnet block.

[0030] Furthermore, the storage of energy by the second spiral spring facilitates the subsequent reset of the fixed rod.

[0031] Preferably, the upper surface of the workbench is slidably connected with a ring of vertical plates at equal angles around the center of the receiving groove. A push plate and a first magnet block are installed on the inner side of the vertical plates, and a first magnet block is provided below the push plate.

[0032] The push plate is arranged in an arc shape at one end near the fixed rod. The length of the push plate is greater than the length of the first magnet block. The fixed rod forms a rotating structure with the support ring plate through the push plate.

[0033] The first magnet and the second magnet are opposite magnetic poles, and the first magnet and the second magnet are arranged in a one-to-one correspondence. The first magnet and the worktable form a sliding structure through the second magnet.

[0034] Furthermore, by setting the first and second magnets as opposite magnetic poles, the second magnet can generate an attractive force on the first magnet, causing the first magnet to move automatically toward the second magnet.

[0035] Preferably, the upper surface of the workbench has a rectangular mounting groove formed at equal angles around the center of the receiving groove.

[0036] A horizontal bar is installed inside the mounting slot, and a vertical plate is slidably connected to the outside of the horizontal bar. A connecting spring is nested on the outside of one end of the horizontal bar.

[0037] Furthermore, the horizontal bars ensure stable sliding of the vertical plates.

[0038] Compared with the prior art, the beneficial effects of the present invention are as follows: This shielded and protective pressure testing machine for microcrystalline glass processing applies a downward striking force to the iron ball assembly when the force plate rotates. The rotation speed of the force plate can be controlled by an external motor, thus adjusting the impact force of the falling iron ball assembly. This convenient adjustment allows the pressure testing machine to meet different usage requirements. The support ring plate drives the shielding cover and sponge layer to move upwards, shielding and protecting the outer sides of the descending iron ball assembly. The sponge not only reduces the noise generated by debris and fragments splashing onto the sponge layer, but also adsorbs small particles and debris. The specific details are as follows:

[0039] As the iron ball assembly falls, an external motor drives the force adjustment rod and the force plate to rotate. This causes the force plate to apply a downward striking force to the iron ball assembly as it rotates. By controlling the rotation speed of the force plate through the external motor, the impact force of the force plate on the falling iron ball assembly can be adjusted. The adjustment is convenient, allowing the pressure testing machine to meet different usage requirements.

[0040] Furthermore, by setting up a manual telescopic rod, it can be ensured that the iron ball assembly falls stably vertically downwards, ensuring that the force plate applies a stable vertical downward striking force to the iron ball assembly, while also preventing the iron ball assembly from shifting its falling position. This makes it easier for the iron ball assembly to apply stable pressure to the microcrystalline glass in the later stages, thereby further improving the accuracy of the pressure resistance tester for the microcrystalline glass.

[0041] When the iron ball assembly moves downward, it applies a downward pull to the control rope. At this time, the other end of the control rope drives the threaded rod to rotate. The rotation of the threaded rod drives the push rod and support ring plate in the lifting automatic control assembly to move upward. This causes the support ring plate to move the shielding cover and the sponge layer upward to shield and protect the outer sides of the descending iron ball assembly, preventing the debris and fragments generated when the iron ball assembly is pressing the microcrystalline glass from flying outward and causing damage. Because the diameter of the shielding cover is small, the debris will not be scattered everywhere, which is convenient for later collection. At the same time, the debris and fragments splash onto the sponge layer. Therefore, the sponge can not only reduce the noise generated by the debris and fragments splashing onto the sponge layer, but also absorb small particles and debris, preventing them from being dispersed in the air.

[0042] The umbrella material shield can be supported by the vertically set fixed rod, so that the shield and sponge layer are in a cylindrical shape for shielding and protection.

[0043] When the shielding cover rises, the second magnet and the corresponding first magnet are attracted by opposite magnetic poles. This causes the first magnet to slide the vertical plate and the push plate inward. As a result, the push plate pushes the fixed rod to tilt. This causes the fixed rod to cause the shielding cover and the sponge layer to form a frustum shape with a smaller upper diameter than a lower diameter. This results in a smaller opening at the top of the shielding cover and the sponge layer, which further improves the shielding and protective effect. Attached Figure Description

Detailed Implementation

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Please see Figures 1-8 The present invention provides the following technical solution:

[0055] Example 1: The pressure testing machine in this example allows for easy adjustment of the punching pressure, meeting various application requirements. See attached diagram for details. Figures 1-3 As shown, the assembly includes a workbench 1 and a support frame 2 with an inverted "L" shape installed on the rear side above the workbench 1. A rotating rod 3 is rotatably mounted on the support frame 2, and a lifting rope 4 is wound around the outside of the rotating rod 3. The rear end of the rotating rod 3 is connected to an external motor. The lower end of the lifting rope 4 passes through the upper surface of the support frame 2 and connects to the middle of the upper surface of the iron ball assembly 5. A manual telescopic rod 8 is installed on the front side above the iron ball assembly 5, and the upper end of the manual telescopic rod 8 is connected to the support frame 2. A force adjustment rod 6 is set on the upper right side of the iron ball assembly 5, and the rear end of the force adjustment rod 6 passes through and is rotatably connected to the rear side of the support frame 2. An inclined force application plate 61 is installed on the left side of the force adjustment rod 6. The iron ball assembly 5 is set below the force application plate 61. The lowest point of the force application plate 61 is higher than the highest point of the iron ball assembly 5, and the lowest point of the force adjustment rod 6 is lower than the highest point of the iron ball assembly 5. The rotational speed of the force application plate 61 is greater than the free fall speed of the iron ball assembly 5.

[0056] Move the entire pressure testing machine to the working area and connect the rotating rod 3 to an external motor. The motor drives the rotating rod 3 to rotate, pulling and winding the lifting rope 4, causing the lower end of the lifting rope 4 to move the iron ball assembly 5 upwards and reset. When the iron ball assembly 5 rises to a certain position, stop the motor. Then place the microcrystalline glass in the middle of the upper surface of the worktable 1. Next, separate the motor from the rotating rod 3 and connect another motor to the rear end of the force adjustment rod 6, causing the other motor to drive the force adjustment rod 6 and the force plate 61 to rotate. When the motor separates from the rotating rod 3, the weight of the iron ball assembly 5 pulls the lifting rope 4 downwards. At this time, the rotating rod 3 rotates and releases the wire. Simultaneously, the force plate 61 rotates and applies a downward impact force to the iron ball assembly 5, thus further increasing the falling speed of the iron ball assembly 5. As the ball falls downwards, the manual telescopic rod 8 is pulled, supporting the iron ball assembly 5 and ensuring it falls vertically downwards. This also prevents the ball assembly 5 from shifting its position during the fall, allowing it to apply stable pressure to the microcrystalline glass. This improves the accuracy of the pressure resistance tester. The rotation speed of the force plate 61 is greater than the falling speed of the iron ball assembly 5. Therefore, when the iron ball assembly 5 begins to fall, the rapid rotation of the force plate 61 applies a downward striking force. The faster the iron ball assembly 5 falls, the greater the impact force on the microcrystalline glass. Thus, by controlling the rotation speed of the force plate 61 via another motor while the iron ball assembly 5 is in free fall, the impact force can be adjusted, allowing the pressure resistance tester to meet different usage requirements.

[0057] Example 2: Based on Example 1, the pressure testing machine in this example can not only shield and protect the debris and fragments generated during pressure testing and facilitate their collection, but also reduce the impact noise caused by debris splashing and adsorb debris and fine particles. See attached diagram for details. Figure 3 and attached Figure 6As shown, the upper surface of the workbench 1 has a ring-shaped receiving groove 102, and a support ring plate 12 is slidably connected inside the receiving groove 102; a protective cover 10 made of umbrella fabric is installed above the support ring plate 12, and a sponge layer 11 is pasted on the inner wall of the protective cover 10; a ring of fixed rods 13 is installed above the support ring plate 12, and the inner wall of the fixed rods 13 is connected to the outer side of the protective cover 10; an automatic lifting control assembly is installed below the support ring plate 12, and the rear side of the receiving groove 102... A threaded rod 14 is rotatably mounted in a slot within the workbench 1. A limit rod 15 is installed in a slot within the workbench 1 on the front side of the receiving slot 102. A first spiral spring 141 is nested and connected to the outer side of the bottom end of the threaded rod 14. The automatic lifting control assembly includes two push rods 16 with an "L" shape structure symmetrically mounted below the support ring plate 12. The push rod 16 on the lower rear side of the support ring plate 12 is threadedly connected to the threaded rod 14. The push rod 16 on the lower front side of the support ring plate 12 is slidably connected to the limit rod 15. The support ring plate 12 and the workbench 1 form a lifting structure through the push rods 16. The lower end of the control rope 7 is wound and connected to the outer side of the upper part of the threaded rod 14, and the upper end of the control rope 7 passes through the interior of the workbench 1 and the support frame 2 and is connected to the upper part of the iron ball assembly 5 through a guide wheel.

[0058] As the iron ball assembly 5 descends, it pulls the upper end of the control rope 7. Guided by the guide wheel, the lower end of the control rope 7 effectively drives the threaded rod 14 to rotate. The first spiral spring 141 stores energy, and the rotating threaded rod 14 drives the outer threaded push rod 16 to rise. At this time, the rear push rod 16 moves the support ring plate 12 upward. The push rod 16 at the lower front end of the support ring plate 12 slides outside the limit rod 15, ensuring the support ring plate 12 moves stably upward within the annular accommodating groove 102. Simultaneously, the support ring plate 12 moves the fixed rod 13, the protective shield 10, and the sponge layer 11 upward together. The fixed rod 13 then pushes against the protective shield 10. The support structure ensures that the protective shield 10 is placed in a cylindrical shape, allowing the umbrella-cloth protective shield 10 and the sponge layer 11 to effectively shield and protect the outer sides of the falling iron ball assembly 5. This prevents the debris and fragments generated by the iron ball assembly 5 during the pressure test of the microcrystalline glass from flying too far outwards and becoming difficult to collect. As a result, the debris and fragments fall inside the protective shield 10, making them easier to collect later. At the same time, the debris and fragments will impact the inner wall of the sponge layer 11 inside the protective shield 10, thus reducing the impact noise and preventing excessive noise from debris flying during the use of the pressure tester. In addition, the sponge layer 11 can also absorb debris and small particles, preventing them from being scattered in the air.

[0059] Because the thread pitch of the threaded rod 14 is large, the rotation of the threaded rod 14 can drive the push rod 16 to move upward quickly. Moreover, the elastic force of the first spiral spring 141 is much smaller than the weight of the iron ball assembly 5. The overall weight of the shielding cover 10, the sponge layer 11, the support ring plate 12 and the fixed rod 13 is small. Therefore, the control rope 7 and the threaded rod 14 will not exert too much resistance on the free fall of the iron ball assembly 5 and will not affect the pressure resistance test of the iron ball assembly 5.

[0060] After the pressure testing machine finishes its work, the sponge layer 11 can be disassembled and replaced.

[0061] Example 3: This example further improves the shielding and protection effect of the withstand voltage testing machine. See attached diagram for details. Figures 7-8 As shown, a movable shaft 18 is rotatably mounted on the upper surface of the support ring plate 12 with slots. A second magnet block 17 is fixed through the outer side of the movable shaft 18, and a second spiral spring 19 is nested and connected to the outer side of the other end of the movable shaft 18. A fixed rod 13 is fixed above the second magnet block 17. A vertical plate 9 is slidably connected at equal angles around the center of the receiving groove 102 on the upper surface of the worktable 1. A push plate 91 and a first magnet block 92 are installed on the inner side of the vertical plate 9. The first magnet block 92 is located below the push plate 91. The end of the push plate 91 near the fixed rod 13 is arranged in an arc shape. The length of the push plate 91 is greater than the length of the first magnet block 92. The fixed rod 13 forms a rotating structure with the support ring plate 12 through the push plate 91. The first magnet block 92 and the second magnet block 17 are opposite magnetic poles. The first magnet block 92 and the second magnet block 17 are arranged in a one-to-one correspondence. The first magnet block 92 forms a sliding structure with the worktable 1 through the second magnet block 17. The upper surface of the workbench 1 has a rectangular mounting groove 101 with the center of the receiving groove 102 as the center. A crossbar 93 is installed inside the mounting groove 101. A vertical plate 9 is slidably connected to the outside of the crossbar 93. A connecting spring 94 is nested on the outside of one end of the crossbar 93.

[0062] When the support ring plate 12 moves the fixed rod 13, the shielding cover 10, and the sponge layer 11 upward to a certain position, the second magnet block 17 below the fixed rod 13 and the corresponding first magnet block 92 attract each other with opposite magnetic poles, causing the corresponding first magnet block 92 to move towards the second magnet block 17. At this time, the first magnet block 92 drives the vertical plate 9 and the push plate 91 to move together towards the second magnet block 17. At this time, the vertical plate 9 slides outside the horizontal bar 93 installed in the mounting groove 101, thus ensuring the stable movement of the vertical plate 9. At the same time, the vertical plate 9 compresses and stores force on the connecting spring 94 when it moves. When the push plate 91 moves, it pushes the fixed rod 13, causing the fixed rod 13 and the second magnet block 17 to rotate around the center of the movable shaft 18. At this time, the second spiral spring 19 stores force, causing the push plate 91, which has an arc shape at one end, to push the fixed rod 13 to be set in an inclined position. Then, the inclined fixed rod 13, in conjunction with the shielding cover 10 and the sponge layer 11, causes the shielding cover 10 and the sponge layer 11 to form a frustum shape with the upper diameter smaller than the lower diameter. Therefore, the upper opening diameter of the shielding cover 10 and the sponge layer 11 is smaller, thereby improving the shielding and protection effect of the shielding cover 10 and the sponge layer 11.

[0063] After the iron ball assembly 5 completes the pressure resistance test on the microcrystalline glass, as described above, the external motor is connected to the rotating rod 3, causing the rotating rod 3 to rotate and wind the lifting rope 4, which in turn causes the lifting rope 4 to move the iron ball assembly 5 upward and reset. At this time, the control rope 7 is released, causing the threaded rod 14 to rotate in the opposite direction through the stored force of the first spiral spring 141, which causes the push rod 16 to drive the support ring plate 12 and the shielding cover 10 to descend. Then, the stored force of the connecting spring 94 drives the vertical plate 9 to reset. The surface of the microcrystalline glass on the workbench 1 can then be observed, and the pressure resistance performance of the microcrystalline glass can be judged, thus completing a series of tasks.

[0064] Example 4: This example discloses another solution for adjusting the impact pressure of the pressure testing machine to meet different testing requirements. The specific operation steps are as follows: A distance sensor is installed on the upper surface of the iron ball assembly 5, allowing the distance sensor to measure the distance between the upper surface of the iron ball assembly 5 and the bottom surface above the support frame 2. First, move the entire pressure testing machine into the working area. Connect the rotating rod 3 to an external motor. The motor drives the rotating rod 3 to rotate, and the rotating rod 3 pulls and winds the lifting rope 4, causing the lower end of the lifting rope 4 to move the iron ball assembly 5 upward. At this time, the distance sensor on the upper surface of the iron ball assembly 5 can detect the distance between it and the bottom surface above the support frame 2 in real time. When the detected distance is 10cm, 20cm, or other values, the distance is... The sensor transmits this signal to the central processing module, which then controls the motor to stop working. The microcrystalline glass is then placed in the middle of the upper surface of the worktable 1. Next, the motor is separated from the rotating rod 3. At this point, the weight of the iron ball assembly 5 pulls the lifting rope 4 downward. The rotating rod 3 rotates and releases the wire. The iron ball assembly 5 then falls automatically, generating a certain impact force on the microcrystalline glass. Therefore, by setting the distance sensor, the iron ball assembly 5 can be controlled to rise to different heights. The higher the iron ball assembly 5 falls, the greater the impact force it generates on the microcrystalline glass. Thus, the pressure resistance of the microcrystalline glass after being subjected to different impact forces can be detected, facilitating the adjustment of the impact pressure of the pressure testing machine and enabling the pressure testing machine to meet different testing needs.
