Description

Technical Field

[0001] The present invention belongs to the technical field of optical glass, and specifically relates to an impact test device for manufacturing optical glass. Background Art

[0002] Optical glass is an inorganic amorphous material designed and prepared with high precision, having excellent optical properties and optimized for controlling light propagation behaviors (such as refraction, reflection, dispersion). The impact test of optical glass is a key test to evaluate its anti-fragmentation performance, energy absorption capacity, and structural integrity under dynamic loads, and most of the test methods adopt the falling ball impact test.

[0003] The Chinese invention patent with the publication number CN117147343B discloses an impact test device for high-strength tempered glass, including a receiving platform and an impact device; a displacement device is arranged above the receiving platform; a mounting frame is fixedly arranged on the displacement device; a first gear is arranged inside the mounting frame, and no meshing teeth are arranged on the lower side of the first gear; a plurality of second gears are evenly arranged around the axis of the first gear, and the first gear and the second gears mesh with each other; a driving device is arranged on the mounting frame; a winding shell is arranged outside the second gear, and the winding shell moves synchronously with the second gear, and a release opening is arranged on the side wall of the winding shell; a rope is wound around a rotating shaft; a small ball is fixedly arranged at the end of the rope; an induction device is arranged on one side of the first gear. The present invention enables the device to automatically recover the small ball after releasing it, eliminating the need to replace the small ball, reducing the workload, and avoiding the influence on the test results when the small ball cannot be recovered after being released.

[0004] The above-mentioned prior art connects a steel ball through a rope, and the steel ball moves downward under its own weight to impact the glass, and then the steel ball is recovered through the rope, achieving the purpose of automatic recovery of the steel ball. Although the steel ball can be recovered, when the steel ball falls to impact the glass, the steel ball will rebound and impact the glass a second time, resulting in additional energy input, making the measured impact energy higher than the initial set value. At the same time, microcracks have been initiated in the glass during the first impact, and the second impact will accelerate the non-natural expansion of the cracks, leading to a distortion of the failure mode (such as changing from radial cracks to reticulated fragmentation), thus affecting the accuracy of the impact test data of the optical glass. Therefore, an impact test device for manufacturing optical glass is proposed now. Summary of the Invention

[0005] To solve the problems raised in the above background art, the present invention provides an impact test device for manufacturing optical glass, which solves the problem that when the existing steel ball falls to impact the glass, the steel ball will rebound and impact the glass a second time, affecting the accuracy of the impact test data.

[0006] To achieve the above object, the present invention provides the following technical solution: An impact test device for manufacturing optical glass, including a receiving platform, and further including: Guide assembly, which is installed on the receiving platform: A support assembly, the support assembly being arranged on the guide assembly; A protection component, the protection component is installed on the support component; A reset component is provided on the guide component; The support assembly includes a first support frame that slides on the guide assembly, a movable frame is movably provided inside the first support frame, a support roller rod is movably installed at one end of the movable frame, guide grooves are opened on both sides of the first support frame, and connecting members that slide in the guide grooves are fixed at both ends of the movable frame; A connecting plate is fixedly mounted on the side of the first support frame, and a second tension spring for pulling the connecting member is provided on the connecting plate; The supporting components are symmetrically arranged on both sides of the guiding component.

[0008] Preferably, a vertical groove for vertical sliding of the first support frame is provided on the side of the guide cover, and the support roller rod is located inside the guide cover; A cylinder is fixedly mounted on the side of the guide cover to drive the first support frame to move along the vertical slot; In the initial state, the movable frame is located at the upper end of the guide groove through the connecting piece. During the downward movement of the steel ball, the support roller rod and the movable frame are pushed to move along the guide groove, and are located at the lower end of the guide groove under the action of the second tension spring, thereby shortening the distance between the two support roller rods.

[0009] Preferably, the support assembly further comprises a protective cover fixedly mounted on the movable frame, the protective cover is connected to the first support frame via a rubber connector, and a rubber sealing pad for sealing the guide groove is provided on the outside of the first support frame.

[0010] Preferably, the protection component includes an annular tube fixedly mounted on the outside of the first support frame, the annular tube is connected to the gas injection equipment, and an air injection hole is provided at the bottom of the annular tube.

[0011] Preferably, a first guide plate and a second guide plate are fixedly mounted on the bottom of the annular tube, a convergent flow channel is formed between the first guide plate and the second guide plate, the air injection hole is located in the convergent flow channel, and the gap between the first guide plate and the second guide plate gradually decreases from top to bottom; When the first support frame is located at the lower end of the vertical slot of the guide cover, the first guide plate is overlapped on the top of the protective baffle.

[0012] Preferably, a second support frame is fixedly mounted on one end of the first support frame, and the second support frame is connected to the annular tube; An actuating rod is movably arranged inside the second support frame. An air inlet hole is formed in the second support frame, and a communication hole is formed in the actuating rod.

[0013] Preferably, transmission gears are fixedly installed at both ends of the movable frame, and sector gears are fixedly installed at both ends of the actuating rod. When the movable frame is located at the upper end of the first support frame, the communication hole does not coincide with the air inlet hole.

At the same time, the airflow is gathered by the first guide plate and the second guide plate to form an air curtain to prevent the debris from splashing, thereby improving the safety of the optical glass impact test. In the present invention, the steel ball drops to push the movable frame and the connecting piece to move along the guide groove to the vertical end of the second support frame, so that the transmission gear meshes with the sector gear. During the downward movement of the movable frame, the sector gear and the actuating rod are driven to rotate by the transmission gear, so that the annular pipe is communicated with the inside of the first support frame, and the gas in the annular pipe enters the first support frame to push the movable frame and the support roller rod to move in the opposite direction along the lower end of the guide groove, thereby increasing the pushing speed of the support roller rod and improving the stability of the support of the steel ball by the support roller rod.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figures 1 to 9 shown, the present invention provides an impact test device for manufacturing optical glass, including a receiving platform 1, and further including: A guiding component 2, the guiding component 2 is installed on the receiving platform 1: A support component 5, the support component 5 is arranged on the guiding component 2; A protective component 4, the protective component 4 is installed on the support component 5; A reset component 3, the reset component 3 is arranged on the guiding component 2; Among them, the support assembly 5 includes a first support frame 51 that slides on the guide assembly 2. An activity frame 52 is movably arranged inside the first support frame 51. One end of the activity frame 52 is movably installed with a support roller rod 55. Guide grooves 59 are formed on both sides of the first support frame 51. Connecting pieces 54 that slide in the guide grooves 59 are fixedly installed at both ends of the activity frame 52; A connecting plate 57 is fixedly installed on the side of the first support frame 51. A second tension spring 58 for pulling the connecting piece 54 is arranged on the connecting plate 57; The support assemblies 5 are symmetrically arranged on both sides of the guide assembly 2; The guide assembly 2 includes a magnetic attraction device 21 fixedly installed on the receiving platform 1. Steel balls 24 are adsorbed at the bottom of the magnetic attraction device 21. A guide cover 22 is fixedly installed outside the magnetic attraction device 21. A protective baffle 25 is fixedly installed at the bottom of the guide cover 22. A rectangular through groove 23 is formed in the middle of the guide cover 22; Vertical grooves for the first support frame 51 to slide vertically are formed on the side of the guide cover 22. The support roller rod 55 is located inside the guide cover 22; A cylinder for driving the first support frame 51 to move along the vertical groove is fixedly installed on the side of the guide cover 22; In the initial state, the activity frame 52 is located at the upper end of the guide groove 59 through the connecting piece 54. During the downward movement of the steel ball 24, the support roller rod 55 and the activity frame 52 are pushed to move along the guide groove 59 and are located at the lower end of the guide groove 59 under the action of the second tension spring 58, thereby shortening the distance between the two support roller rods 55.

[0020] By placing the optical glass on the receiving platform 1, the steel ball 24 adsorbed by the power-off magnetic attraction device 21 vertically falls and impacts the optical glass. During the falling process, the two support assemblies 5 are pushed to move in opposite directions, so that the activity frame 52 moves along the guide groove 59 to the vertical end through the connecting piece 54. At this time, the activity frame 52 and the support roller rod 55 move in the opposite direction along the lower end of the guide groove 59 under the action of the second tension spring 58, thereby reducing the distance between the two support roller rods 55. During the rebounding process of the steel ball 24, the two support roller rods 55 move downward and shorten the distance between them. The steel ball 24 is supported by the two support roller rods 55 to prevent the steel ball 24 from rebounding and impacting the optical glass for the second time, thereby ensuring the accuracy of the optical glass impact test.

[0021] It is hereby stated that on the basis of not deviating from the present application, a guide rail mechanism is added to the connection method between the magnetic attraction device 21 and the receiving platform 1, so that the guide assembly 2 can move horizontally, longitudinally and vertically on the receiving platform 1 to realize multi-point tests and tests at different heights of the optical glass.

[0022] Such as Figure 3 And Figure 9As shown, the support assembly 5 further includes a protective cover 53 fixed on the movable frame 52. The protective cover 53 is connected to the first support frame 51 via a rubber connector 56. A rubber sealing gasket 50 is provided on the outside of the first support frame 51 to seal the guide groove 59. The protection assembly 4 includes an annular tube 41 fixed to the outside of the first support frame 51. The annular tube 41 is connected to the gas injection device, and an air injection hole is opened at the bottom of the annular tube 41. A first guide plate 42 and a second guide plate 43 are fixedly mounted on the bottom of the annular tube 41. A convergent flow channel is formed between the first guide plate 42 and the second guide plate 43. The air injection holes are located in the convergent flow channel. The gap between the first guide plate 42 and the second guide plate 43 gradually decreases from top to bottom. When the first support frame 51 is located at the lower end of the vertical slot of the guide cover 22 , the first guide plate 42 overlaps the top of the protective baffle 25 .

[0023] Gas is injected into the annular tube 41 through the gas injection equipment. When the steel ball 24 falls to perform an impact test on the optical glass, the protective baffle 25 protects the flying debris generated by the impact. At the same time, the air flow is gathered by the first guide plate 42 and the second guide plate 43 to form an air curtain to prevent the flying of debris, thereby improving the safety of the optical glass impact test.

[0024] The middle part of the receiving platform 1 is a mesh structure, and the optical glass is located on the top of the mesh structure. When the air curtain is gathered and injected into the middle part, the gas is discharged through the mesh structure to prevent the air flow from being discharged from all sides and carrying optical glass fragments.

[0025] like Figure 3 、 Figure 7 and Figure 9 As shown, a second support frame 511 is fixedly mounted on one end of the first support frame 51 , and the second support frame 511 is connected to the annular tube 41 ; The second support frame 511 is provided with a movable rod 516 movably disposed therein. The second support frame 511 is provided with an air inlet 513 , and the movable rod 516 is provided with a communication hole 514 . Transmission gears 512 are fixedly mounted on both ends of the movable frame 52, and sector gears 515 are fixedly mounted on both ends of the movable rod 516; When the movable frame 52 is located at the upper end of the first support frame 51, the communication hole 514 does not overlap with the air inlet hole 513; When the movable frame 52 moves along the guide groove 59 through the connecting member 54 , the transmission tooth 512 engages with the sector gear 515 and drives the movable rod 516 to rotate, thereby connecting the air inlet 513 with the annular tube 41 through the connecting hole 514 .

[0026] The steel ball 24 drops to push the movable frame 52 and the connecting member 54 to move along the guiding groove 59 towards the second support frame 511 until reaching the vertical end of the guiding groove 59, causing the transmission gear 512 to mesh with the sector gear 515. During the downward movement of the movable frame 52, the sector gear 515 and the movable rod 516 are driven to rotate through the transmission gear 512, enabling the annular pipe 41 to communicate with the inside of the first support frame 51. The gas in the annular pipe 41 enters the first support frame 51 to push the movable frame 52 and the support roller rod 55 to move in the reverse direction along the lower end of the guiding groove 59, thereby increasing the pushing speed of the support roller rod 55 and simultaneously enhancing the stability of the support of the support roller rod 55 on the steel ball 24.

[0027] As Figure 7 shown in Figure 8 Fig. 7, the reset assembly 3 includes a guide frame 31 fixedly installed outside the guide cover 22. A guide rod 34 is hinged to the top of the guide frame 31. A first tension spring 33 for pulling the guide rod 34 is arranged on the guide frame 31, and a damping pad 32 is arranged on the side of the guide frame 31.

[0028] After the steel ball 24 drops to impact the optical glass, the support roller rod 55 supports the steel ball 24 to prevent it from secondarily impacting the optical glass. At this time, the air cylinder retracts to drive the support assembly 5 and the steel ball 24 to move upward along the guide cover 22, and the steel ball 24 is adsorbed by the magnetic attraction device 21 during the upward movement; Meanwhile, during the upward movement of the connecting member 54, the guide rod 34 is pushed to rotate and is located at the top of the guide rod 34. Then, the air cylinder pushes the first support frame 51 downward. The connecting member 54 is guided by the guide rod 34 to move along the guiding groove 59 to the vertical end. At this time, the connecting member 54 contacts the damping pad 32 and moves downward, and under the action of the friction force of the damping pad 32, the connecting member 54 moves upward along the vertical end of the guiding groove 59 and is reset at the upper end of the guiding groove 59 under the guidance of the guiding groove 59 for recycling.

[0029] The working principle and usage process of the present invention: The optical glass is placed on the receiving platform 1, and the steel ball 24 adsorbed by the power-off magnetic attraction device 21 drops vertically to impact the optical glass. During the dropping process, the two support assemblies 5 are pushed to move in opposite directions, causing the movable frame 52 to move along the guiding groove 59 to the vertical end through the connecting member 54. At this time, the movable frame 52 and the support roller rod 55 move in the reverse direction along the lower end of the guiding groove 59 under the action of the second tension spring 58, thereby reducing the distance between the two support roller rods 55. During the rebound process of the steel ball 24, the two support roller rods 55 move downward and shorten the distance between them. The two support roller rods 55 support the steel ball 24 to prevent the steel ball 24 from rebounding and secondarily impacting the optical glass; When the steel ball 24 drops for the impact test on the optical glass, the protective baffle 25 is used to protect against the flying debris generated by the impact. At the same time, the airflow is gathered by the first guide plate 42 and the second guide plate 43 to form an air curtain to prevent the debris from splashing; The dropping of the steel ball 24 pushes the movable frame 52 and the connecting piece 54 to move along the guide groove 59 towards the second support frame 511 until the vertical end of the guide groove 59, causing the transmission gear 512 to mesh with the sector gear 515. During the downward movement of the movable frame 52, the sector gear 515 and the movable rod 516 are driven to rotate by the transmission gear 512, enabling the annular pipe 41 to communicate with the inside of the first support frame 51. The gas in the annular pipe 41 enters the first support frame 51 to push the movable frame 52 and the support roller rod 55 to move in the reverse direction along the lower end of the guide groove 59, thereby increasing the pushing speed of the support roller rod 55 and enhancing the stability of the support of the steel ball 24 by the support roller rod 55; After the steel ball 24 impacts the optical glass, the support roller rod 55 supports the steel ball 24 to prevent it from hitting the optical glass again. At this time, the cylinder retracts to drive the support assembly 5 and the steel ball 24 to move upward along the guide cover 22. During the upward movement, the steel ball 24 is adsorbed by the magnetic adsorption device 21; Meanwhile, during the upward movement of the connecting piece 54, the guide rod 34 is pushed to rotate and is located at the top of the guide rod 34. Then, the cylinder pushes the first support frame 51 downward. Guided by the guide rod 34, the connecting piece 54 moves along the guide groove 59 to the vertical end. At this time, the connecting piece 54 contacts the damping pad 32 and moves downward, and under the action of the friction force of the damping pad 32, the connecting piece 54 moves upward along the vertical end of the guide groove 59 and is reset to the upper end of the guide groove 59 under the guidance of the guide groove 59 for recycling.
