Description

Technical Field

[0001] The present invention relates to the technical field of pressure resistance detection in microcrystalline glass processing, and in particular to a shielding and protective pressure resistance detection machine for microcrystalline glass processing. Background Art

[0002] Glass-ceramics is one of many new materials. As glass-ceramics has the advantages of high light transmittance, high hardness and high toughness, it has well demonstrated the performance advantages of new materials. Therefore, it is widely used in cameras, mobile phone covers, tablets and automotive glass. After the production and processing of glass-ceramics, a pressure tester is also needed to test the pressure resistance of glass-ceramics, so as to judge whether the production of glass-ceramics is qualified. The patent name disclosed in the prior art with the announcement number "CN113075063B" is "A glass comparison impact test device". The complete glass is placed inside the support block, and the four corners are stuck in the placement block. After the height adjustment of the stage and the iron ball is completed, the pull rod is manually pulled, and the guide original is rotated through the transmission shaft to close the baffle inward. The stopper passes through the support column, and the spring is compressed. After adjusting 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 fixes the stage, completes the positioning, starts the servo motor, and the iron ball falls down and hits the complete glass. The broken glass slag falls into the storage box. After the test is completed, people pull the handle to pull out the storage box and properly collect the glass slag, so as to ensure the safety of people's use while facilitating the collection of glass slag. 1. The pressure tester described above detects the pressure resistance of glass by starting the servo motor and dropping an iron ball to hit the intact glass. If the impact force of the iron ball falling down needs to be adjusted, in addition to replacing iron balls of different sizes, the impact force of the iron ball falling down can only be adjusted by adjusting the height of the iron ball. Each time, a ruler is required to measure the placement height of the iron ball, so it is not convenient to adjust the impact force of the iron ball falling down; The patent name disclosed in the prior art with the announcement number "CN116448581B" is "A kind of RV glass compressive strength detection device", which is connected to the connecting gear through a rotating shaft. When the first connecting rack pushes the connecting gear to rotate, the main bevel gear plate and the secondary bevel gear plate can be driven to rotate through the connection of the rotating shaft, and the secondary bevel gear plate 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 synchronously driven to flip to fit with the frame. In this way, in the process of hitting the glass, the protective door blocks the debris, which can prevent the debris from splashing out of the frame and causing danger to the staff. When the glass moves out from the bottom of the protective mechanism, the protective door is reset, and the power for the operation of the dust removal mechanism, the extrusion mechanism and the protective mechanism are all driven by the adjusting cylinder, which reduces the number of power supplies. Through the setting of the protective door, it is convenient for the staff to replace the impact heads of different weights. When the protective door is reset, it can be replaced. Through the setting of the transparent observation window, the situation when the glass hits can be observed; 2. Although the protective door provided in the above-mentioned withstand voltage testing machine can block the debris and prevent the debris from splashing out of the frame, the debris will produce a certain impact force on the inner wall of the frame and the inner wall of the protective door, making the noise louder, so it cannot provide good shielding and protection. Moreover, since the protective frame composed of the protective door and the frame has a large area, the debris will be randomly scattered in various positions in the protective frame composed of the protective door and the frame, which is not convenient for subsequent collection work. Summary of the invention

[0003] The object of the present invention is to provide a shielding and protective pressure resistance testing machine for microcrystalline glass processing, so as to solve the problem proposed by the above-mentioned background technology that the impact force of the iron ball falling downward can only be adjusted by adjusting the height of the iron ball, and the placement height of the iron ball needs to be measured by a ruler each time, so it is not convenient to adjust the impact force of the iron ball falling downward, and the debris will produce a certain impact force on the inner wall of the frame and the inner wall of the protective door, resulting in a large noise, so it cannot be well shielded and protected, and because the area of ​​the protective frame composed of the protective door and the frame is large, the debris will be scattered randomly at various positions in the protective frame composed of the protective door and the frame, which is not convenient for subsequent collection work.

[0008] 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, thereby increasing the descending speed of the iron ball assembly and thereby increasing the downward impact force of the iron ball assembly.

[0009] Preferably, a threaded rod is rotatably installed in a slot in the workbench at the rear side of the accommodating groove, a limiting rod is installed in a slot in the workbench at the front side of the accommodating groove, and a first vortex spring is nested and connected to the outer side of the bottom end of the threaded rod.

[0010] Furthermore, the threaded rod and the limiting rod can be placed conveniently by opening grooves in the workbench. Meanwhile, the grooves in the workbench can also limit the push rod, so that the push rod can move up and down stably.

[0011] Preferably, the lifting automatic control assembly includes two push rods in an "L" shape symmetrically installed below the support ring plate, and a threaded rod is threadedly connected to the push rod below the rear side of the support ring plate; Furthermore, the push rod connected with the outer thread can be driven to rise by the rotating shaft of the threaded rod.

[0020] Furthermore, by setting the first magnet block and the second magnet block to have opposite magnetic poles, the second magnet block can generate an adsorption force on the first magnet block, so that the first magnet block automatically moves in the direction of the second magnet block.

[0021] Preferably, a circle of installation grooves in a rectangular structure is provided on the upper surface of the workbench at equal angles with the center of the accommodating groove as the center; A cross bar is installed inside the installation groove, a vertical plate is slidably connected to the outer side of the cross bar, and a connecting spring is nested and connected to the outer side of one end of the cross bar.

[0022] Furthermore, by setting the cross bar, the stable sliding of the vertical board can be ensured.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the shielding and protective pressure-resistant testing machine for glass-ceramic processing applies a downward beating force to the iron ball assembly when the force plate rotates, and then the rotation speed of the force plate is controlled by an external motor, so that the impact force of the force plate on the falling iron ball assembly can be controlled to adjust, and the adjustment is convenient, so that the pressure-resistant testing machine can meet different usage requirements, and the supporting ring plate drives the shielding protective cover and the sponge layer to move upward to shield and protect the outer sides of the iron ball assembly after the iron ball assembly is dropped. The sponge can not only reduce the noise generated by the splashing of debris and fragments onto the sponge layer, but also absorb tiny particles and debris. The specific contents are as follows: When the iron ball assembly falls, the external motor drives the force adjustment rod and the force plate to rotate, so that the force plate applies a downward slapping force to the iron ball assembly when it rotates. Then, the rotation speed of the force plate is controlled by the external motor, so that the impact force of the iron ball assembly falling can be controlled by the force plate. The adjustment is convenient, so that the pressure tester can meet different usage requirements. Furthermore, by setting the manual telescopic rod, it can be ensured that the iron ball assembly stably falls vertically downward, and the force plate stably applies a vertical downward beating force to the iron ball assembly, while preventing the iron ball assembly from shifting in the falling position, so that the iron ball assembly can apply a stable pressure to the microcrystalline glass in the later stage, and then the accuracy of the pressure resistance test of the microcrystalline glass by the pressure resistance test machine in the later stage can be further improved; When the iron ball assembly moves downward, it will exert a downward pulling force on 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 the support ring plate in the lifting automatic control assembly to move upward, so that the support ring plate drives the shielding protective cover and the sponge layer to move upward to shield and protect the surrounding outer sides of the iron ball assembly after the descent, so as to prevent the debris and fragments generated by the iron ball assembly when stamping the microcrystalline glass from splashing outward and causing damage. Since the diameter of the shielding protective cover is small, the debris will not be scattered everywhere at will, which is convenient for the later collection work. At the same time, the debris and fragments splash onto the sponge layer, so that the sponge can not only reduce the noise generated by the debris and fragments splashing onto the sponge layer, but also absorb the tiny particles and debris to prevent the tiny particles and debris from floating in the air. The shielding and protective cover made of an umbrella material can be supported by a vertically arranged solid rod, so that the shielding and protective cover and the sponge layer are in a cylindrical shape for shielding and protective operations; When the shielding protective cover rises, the second magnet block and the first magnet block at the corresponding position are attracted by opposite magnetic poles, and then the first magnet block drives the vertical plate and the push plate to slide inward, so that the push plate pushes the solid rod to be inclined, and then a circle of solid rods drives the shielding protective cover and the sponge layer to be a truncated cone shape with an upper diameter smaller than a lower diameter, and then the upper openings of the shielding protective cover and the sponge layer are smaller, which can further improve the shielding protection effect of the shielding protective cover and the sponge layer.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 8 , the present invention provides the following technical solutions: Embodiment 1: The pressure tester in this embodiment is convenient for adjusting the pressure intensity and can meet different usage requirements. Figure 1-Figure 3 As shown, it includes a workbench 1 and a support frame 2 in an inverted "L" shape structure installed on the upper rear side of the workbench 1; a rotating rod 3 is rotatably installed on the support frame 2, and a lifting rope 4 is wound around the outer side of the rotating rod 3, and 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 is connected to the middle position of the upper surface of the iron ball assembly 5, and a manual telescopic rod 8 is installed on the upper front side of 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 arranged on the upper right side of the iron ball assembly 5, and the rear end of the force adjustment rod 6 passes through the rear side surface of the support frame 2, and an inclined force plate 61 is installed on the left side of the force adjustment rod 6, and the iron ball assembly 5 is arranged below the force plate 61, the lowest point of the force plate 61 is higher than the highest point of the iron ball assembly 5, the lowest point of the force adjustment rod 6 is lower than the highest point of the iron ball assembly 5, and the rotation speed of the force plate 61 is greater than the free fall speed of the iron ball assembly 5.

[0028] Move the entire pressure resistance testing machine into the working area, connect the rotating rod 3 with the external motor, the motor drives the rotating rod 3 to rotate, the rotating rod 3 pulls and reels the lifting rope 4, so that the lower end of the lifting rope 4 drives the iron ball assembly 5 to move upward and reset, when the iron ball assembly 5 rises to a certain position, stop the motor at this time, and then place the microcrystalline glass in the middle position on the upper surface of the workbench 1, and then separate the motor from the rotating rod 3, and connect another motor to the rear end of the force adjustment rod 6, so that the other motor drives the force adjustment rod 6 and the force plate 61 to rotate, when the motor is separated from the rotating rod 3, the gravity of the iron ball assembly 5 pulls the lifting rope 4 downward, and the rotating rod 3 rotates and releases the line, and at the same time, the force plate 61 applies a downward impact force to the iron ball assembly 5 when it rotates, thereby further increasing the falling speed of the iron ball assembly 5. When falling downward, the manual telescopic rod 8 is pulled at the same time, so that the manual telescopic rod 8 supports the iron ball assembly 5, ensuring that the iron ball assembly 5 always falls vertically downward, and at the same time avoiding the deviation of the falling position of the iron ball assembly 5. Therefore, the iron ball assembly 5 can apply stable pressure to the microcrystalline glass in the later stage, which is convenient for improving the accuracy of the pressure resistance detection of the microcrystalline glass by the later pressure resistance testing machine, so that 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 just starts to fall, the force plate 61 rotates quickly, which can make the force plate 61 apply a downward slapping force to the iron ball assembly 5. Therefore, the faster the falling speed of the iron ball assembly 5, the greater the impact force of the iron ball assembly 5 on the microcrystalline glass. Therefore, when the iron ball assembly 5 is free falling, the rotation speed of the force plate 61 is controlled by another motor, so that the falling impact force of the iron ball assembly 5 can be adjusted, so that the pressure resistance testing machine can meet different usage requirements.

[0029] Embodiment 2: Based on Embodiment 1, the pressure tester in this embodiment can not only shield and protect the debris and fragments generated by the pressure test and facilitate collection, but also reduce the impact noise generated by the splashing of debris and absorb the debris and tiny particles. For details, please refer to the attached Figure 3 and attached Figure 6 As shown, a receiving groove 102 with a circular ring structure is provided on the upper surface of the workbench 1, and a supporting ring plate 12 is slidably connected inside the receiving groove 102; a shielding protective cover 10 made of umbrella cloth is installed above the supporting ring plate 12, and a sponge layer 11 is pasted on the inner side wall of the shielding protective cover 10; a circle of fixing rods 13 is installed above the supporting ring plate 12, and the inner side wall of the fixing rods 13 is connected to the outer side of the shielding protective cover 10; an automatic lifting control component is installed below the supporting ring plate 12, and the rear side of the receiving groove 102 is connected to the inner side wall of the supporting ring plate 12. A threaded rod 14 is rotatably installed in the groove in the workbench 1, and a limit rod 15 is installed in the groove in the workbench 1 in front of the accommodating groove 102. A first vortex spring 141 is nested and connected to the outer side of the bottom end of the threaded rod 14. The lifting automatic control component includes two push rods 16 in an "L" shape structure symmetrically installed below the support ring plate 12. The push rod 16 below the rear side of the support ring plate 12 is threadedly connected to the threaded rod 14; the push rod 16 below the front side of the support ring plate 12 is slidably connected to the limit rod 15. The support ring plate 12 forms a lifting structure with the workbench 1 through the push rod 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 inside of the workbench 1 and the support frame 2 and is connected to the upper part of the iron ball assembly 5 through the guide wheel.

[0030] When the iron ball assembly 5 is in the process of descending, the iron ball assembly 5 will pull the upper end of the control rope 7. Since the control rope 7 is guided by the guide wheel, the lower end of the control rope 7 can well drive the threaded rod 14 to rotate, and the first vortex spring 141 accumulates force. When the threaded rod 14 rotates, it drives the push rod 16 connected to the outer thread to rise. At this time, the push rod 16 on the rear side drives the support ring plate 12 to move upward. At this time, the push rod 16 at the lower end of the front side of the support ring plate 12 slides on the outside of the limit rod 15, thereby ensuring that the support ring plate 12 stably moves upward in the accommodating groove 102 with a circular ring-shaped structure. At this time, the support ring plate 12 drives the fixing rod 13, the shielding protective cover 10 and the sponge layer 11 to move upward together, and the fixing rod 13 pushes the shielding protective cover 10 The shielding protective cover 10 is supported so that the cylindrical structure is placed, so that the shielding protective cover 10 made of umbrella cloth and the sponge layer 11 can well shield and protect the outer sides of the falling iron ball assembly 5, and prevent the debris and fragments generated by the iron ball assembly 5 when performing pressure resistance test on the microcrystalline glass from splashing too far outward and being inconvenient to collect. Therefore, the debris and fragments fall on the inner side of the shielding protective cover 10, which is convenient for later collection. At the same time, the debris and fragments will hit the inner wall of the sponge layer 11 on the inner side of the shielding protective cover 10, so the sponge layer 11 can reduce the noise of impact, and avoid the noise of debris splashing when the pressure resistance testing machine is in use. At the same time, the sponge layer 11 can also absorb the debris and tiny particles, and prevent the debris and tiny particles from floating in the air at will.

[0031] Since the pitch of the thread on the surface of the threaded rod 14 is large, the threaded rod 14 can drive the push rod 16 to move upward quickly when it rotates, and the elastic force of the first vortex spring 141 is much smaller than the gravity of the iron ball assembly 5. The overall weight of the shielding protective cover 10, sponge layer 11, support ring plate 12 and solid rod 13 is relatively small. Therefore, the control rope 7 and the threaded rod 14 will not exert too much resistance to the free fall of the iron ball assembly 5, and will not affect the pressure resistance detection work of the iron ball assembly 5.

[0032] When the pressure test machine finishes working, the sponge layer 11 can be disassembled and replaced.

[0033] Embodiment 3: In this embodiment, the shielding and protection effect of the pressure tester can be further improved. Figure 7-Figure 8As shown, a circle of movable shaft rod 18 is rotatably installed on the upper surface of the support ring plate 12, and a second magnet block 17 is fixedly inserted through the outer side of the movable shaft rod 18, and a second vortex spring 19 is nested and connected to the outer side of the other end of the movable shaft rod 18, and a solid rod 13 is fixed above the second magnet block 17. A circle of vertical plates 9 are slidably connected to the upper surface of the workbench 1 with the center of the circle of the accommodating groove 102 as the center of the circle, and a push plate 91 and a first magnet block 92 are installed on the inner side of the vertical plate 9, and the first magnet block 92 is arranged below the push plate 91; the end of the push plate 91 close to the solid rod 13 is arranged in an arc-shaped structure, and the length of the push plate 91 is greater than the length of the first magnet block 92, and the solid 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 of different magnetic poles, and the first magnet block 92 and the second magnet block 17 are arranged one by one, and the first magnet block 92 forms a sliding structure with the workbench 1 through the second magnet block 17. The upper surface of the workbench 1 is provided with a circle of rectangular mounting grooves 101 with equal angles with the center of the accommodating groove 102 as the center; a cross bar 93 is installed inside the mounting groove 101, and a vertical plate 9 is slidably connected to the outer side of the cross bar 93, and a connecting spring 94 is nested and connected to the outer side of one end of the cross bar 93.

[0034] When the support ring plate 12 drives the solid rod 13, the shielding protective cover 10 and the sponge layer 11 to move upward to a certain position, the second magnet block 17 under the solid rod 13 and the first magnet block 92 at the corresponding position are attracted to each other by opposite magnetic poles, and then the first magnet block 92 at the corresponding position moves toward the direction of 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 in the direction of the second magnet block 17. At this time, the vertical plate 9 slides on the outside of the cross bar 93 installed in the installation groove 101, thereby ensuring the stable movement of the vertical plate 9. At the same time, when the vertical plate 9 moves, it squeezes and accumulates force on the connecting spring 94 When the push plate 91 moves, it pushes the solid rod 13, so that the solid rod 13 and the second magnet block 17 rotate with the center of the movable shaft rod 18 as the center. At this time, the second vortex spring 19 accumulates force, so that the push plate 91 with an arc shape at one end pushes the solid rod 13 to be set in an inclined state, and then the cooperation of the inclined circle of solid rods 13 drives the shielding protective cover 10 and the sponge layer 11 to be in the shape of a truncated cone with an upper diameter smaller than the lower diameter, so that the upper opening diameter of the shielding protective cover 10 and the sponge layer 11 is smaller, thereby improving the shielding and protection effect of the shielding protective cover 10 and the sponge layer 11.

[0035] After the iron ball assembly 5 has completed the pressure resistance test on the microcrystalline glass, at this time, as shown above, the external motor is connected to the rotating rod 3, so that the rotating rod 3 rotates to reel in the lifting rope 4, so that the lifting rope 4 drives the iron ball assembly 5 to move upward and reset, and then the control rope 7 is paid out, so that the threaded rod 14 rotates in the opposite direction through the stored force of the first vortex spring 141, so that the push rod 16 drives the support ring plate 12 and the shielding protective cover 10 to descend, and then the vertical plate 9 is reset by the stored force of the connecting spring 94, and then the surface of the microcrystalline glass on the workbench 1 can be viewed, and then the pressure resistance performance of the microcrystalline glass can be judged, thereby completing a series of tasks.

[0036] Embodiment 4: This embodiment discloses another scheme that can adjust the punching force of the pressure tester, and then can meet different detection requirements. The specific operation steps are as follows: a distance sensor is installed on the upper surface of the iron ball assembly 5, so that the distance sensor can measure the distance between the upper surface of the iron ball assembly 5 and the upper bottom surface of the support frame 2. First, move the entire pressure tester into the working area, connect the rotating rod 3 with the external motor, the motor drives the rotating rod 3 to rotate, and the rotating rod 3 pulls and reels the pulling rope 4, so that the lower end of the pulling rope 4 drives the iron ball assembly 5 to move 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 upper bottom surface of the support frame 2 in real time. When the distance is detected to be 10cm or 20cm or other values, the distance The sensor transmits this signal to the central processing module, at which point the central processing module controls the motor to stop working, and then places the microcrystalline glass in the middle position on the upper surface of the workbench 1, and then separates the motor from the rotating rod 3. At this point, the iron ball assembly 5 is pulled downward by its own gravity to pull the pull rope 4, and the rotating rod 3 then rotates and releases the wire, and then the iron ball assembly 5 automatically falls, producing 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 height of the iron ball assembly 5 that falls, the greater the impact force that the iron ball assembly 5 produces on the microcrystalline glass. Therefore, the pressure resistance of the microcrystalline glass after being subjected to different impact forces can be detected, which facilitates the adjustment of the punching strength of the pressure resistance testing machine, so that the pressure resistance testing machine can meet different testing requirements.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
