Technical Field
[0001] This invention relates to the field of glass testing equipment technology, and specifically to a glass panel impact testing device. Background Technology
[0002] Glass panels are widely used in household appliances; for example, most refrigerators use doors with glass panels. These panels need to undergo impact testing to determine their strength. Currently, most glass panel impact testing equipment uses a falling ball impact tester. However, existing falling ball impact testers lack protective devices, making it easy for the ball to accidentally fall and injure operators. Furthermore, glass fragments generated after the test tend to accumulate inside the tester, making cleaning difficult and reducing testing efficiency for subsequent tests. Summary of the Invention
[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a glass panel impact testing device that has advantages such as preventing the sphere from accidentally falling and facilitating the cleaning of glass fragments after the test.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a glass panel impact testing device, comprising: Impact seat, with an impact platform groove provided on the top surface of the impact seat; The impact table is rotatably mounted in the impact table slot via a tilting shaft. Clamping components are provided on both opposite side walls of the impact table; Impact test steel ball assembly, the impact test steel ball assembly is set on the top surface of the impact seat away from the end of the impact table groove; The impact table is a groove-shaped structure with an open top surface, and a discharge port is provided on the side wall of the impact table away from the clamping component. The clamping assembly includes a threaded rod that is movably disposed through the side wall of the impact table. A pressure plate and a locking nut are respectively movably disposed at both ends of the threaded rod along its length, and the pressure plate is located inside the impact table. The impact test steel ball assembly includes a test frame vertically mounted on the top surface of the impact seat. A ball is movably attracted to the test frame by an electromagnet. The position of the ball corresponds vertically to the position of the impact table. A support ring is movably mounted below the ball.
[0005] Preferably, the flipping shaft is rotatably positioned at the end of the impact table groove away from the impact test steel ball assembly, so that when the glass panel impact test is completed and broken glass is generated inside the impact table, the impact table can be flipped to facilitate the cleaning of the broken glass.
[0006] Preferably, a drive motor is rotatably mounted on the top surface of the impact seat near the impact table end. A pressure shaft is coaxially mounted on the output shaft of the drive motor. Multiple pressure plates corresponding to the position of the impact table are mounted on the pressure shaft. The pressure plates abut against the opening on the top surface of the impact table. The drive motor drives the pressure shaft to rotate, thereby pressing and fixing the impact table through the pressure plates, which facilitates the stability of the impact table when the glass panel is subjected to impact testing.
[0007] Preferably, the pressure plate is provided with a stepped through groove adapted to the threaded rod, and a stepped plate adapted to the stepped through groove is rotatably provided on the threaded rod. The stepped plate is movably disposed in the stepped through groove. The side wall of the pressure plate near the bottom of the impact table has an arc-shaped structure, which makes it easy to adjust the position of the pressure plate according to the glass panel of different thicknesses, so that the glass panel can be pressed and fixed by the pressure plate.
[0008] Preferably, the locking nut abuts against the side wall of the impact table, making it easy to tighten the locking nut. At the same time, it can fix the pressure plate under the combined action of the step plate, thereby realizing the pressing and fixing of the glass panel.
[0009] Preferably, the test frame is equipped with a movable sleeve, and a lifting cylinder is provided on the top surface of the impact seat. The piston rod of the lifting cylinder is connected to the movable sleeve. A horizontal bar is provided on the movable sleeve, and a ball seat is provided on the end of the horizontal bar away from the movable sleeve. The bottom surface of the ball seat is open, and an electromagnet is embedded in the top of the opening on the bottom surface of the ball seat. The ball is movably positioned in the opening on the bottom surface of the ball seat. According to different test requirements, the lifting cylinder can be activated to drive the ball seat to adjust its position in the vertical direction, so that the ball can fall from different heights and thus achieve different test effects.
[0010] Preferably, the bottom opening of the ball seat is circular, and the diameter of the bottom opening of the ball seat is larger than the diameter of the ball, so as to facilitate the placement of balls of different diameters as needed to achieve different test results.
[0011] In this configuration, multiple adjusting threaded rods are evenly distributed circumferentially on the outer peripheral wall of the ball seat. The adjusting threaded rods move through the outer peripheral wall of the ball seat to the bottom opening of the ball seat. Depending on the diameter of the ball, the adjusting threaded rods can be rotated to allow different lengths of the adjusting threaded rods to penetrate into the ball seat, thereby facilitating the stability of the ball's position when it is placed in the bottom opening of the ball seat.
[0012] Preferably, the support ring comprises: Rotate the motor base, which is connected to the piston rod of the lifting cylinder; A rotating motor is embedded inside a rotating motor housing. The annular support ring is horizontally connected to the output shaft of the rotating motor via a connecting rod. This allows the rotating motor to be started and rotated to the underside of the ball after the ball is attracted to the electromagnet, thus preventing the ball from falling accidentally.
[0013] Preferably, the inner diameter of the annular support is smaller than the diameter of the ball, and the axis of the annular support and the axis of the output shaft of the rotating motor are both perpendicular to the horizontal plane. When the ball falls accidentally, it can fall onto the annular support, preventing the ball from falling onto the impact platform.
[0014] The beneficial effects of the present invention are as follows: 1. The setting of the support ring can prevent the ball from falling accidentally. It can fall onto the circular support ring seat, thereby avoiding the ball falling directly onto the impact platform and causing personnel injury.
[0015] 2. A discharge port is provided on the side wall of the impact table away from the clamping component. The glass fragments generated during the test can be poured out through the discharge port by flipping the impact table, which is convenient for the operators to clean up and facilitates the subsequent test, thus improving the work efficiency and ease of operation.
[0016] 3. The clamping components are designed to allow for adjustment of the pressure plate position when testing glass panels of different thicknesses is required. This allows the pressure plate to press and fix glass panels of different thicknesses, improving the versatility of the tests. Attached Figure Description

[0027] 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.
[0028] Example 1 like Figures 1 to 7As shown, the present invention provides a glass panel impact testing device, including an impact seat 1, an impact table groove 11 provided on the top surface of the impact seat 1; an impact table 2 rotatably disposed in the impact table groove 11 via a flipping shaft 3; clamping assemblies 4 are provided on the opposite side walls of the impact table 2; an impact test steel ball assembly 5 is disposed on the top surface of the impact seat 1 away from the impact table groove 11; the impact table 2 is a groove-shaped structure with an open top surface, and a discharge port 21 is provided on the side wall of the impact table 2 away from the clamping assembly 4; the clamping assembly 4 includes a threaded rod 41 movably disposed through the side wall of the impact table 2, and a pressure plate 42 and a locking nut 43 are movably disposed at both ends of the threaded rod 41 along its length, and the pressure plate 42 is located inside the impact table 2; the impact test steel ball assembly 5 includes a test frame 51 vertically disposed on the top surface of the impact seat 1, and a ball 53 is movably attracted on the test frame 51 by an electromagnet 52, the position of the ball 53 corresponding vertically to the position of the impact table 2, and a support ring 54 is movably disposed below the ball 53.
[0029] Before conducting the impact test on the glass panel, the impact table 2 is rotated into the impact table slot 11 around the flipping shaft 3. The glass panel is then placed horizontally in the opening on the top surface of the impact table 2. Rotating the threaded rod 41 allows the pressure plate 42 to press onto the glass panel, and tightening the locking nut 43 secures the glass panel through the pressure plate 42. Before the test, the ball 53 is attached to the electromagnet 52, and the support ring 54 is positioned directly below the ball 53. During the test, the support ring 54 is moved to a position offset from the ball 53, and the electromagnet 52 is turned off, causing the ball 53 to fall onto the glass panel. The test conclusion can then be drawn based on the height from which the ball 53 falls from the test frame 51 and the damage to the glass panel.
[0030] When the glass panel impact test is completed and the glass panel breaks, the impact table 2 can be flipped over so that the glass fragments in the impact table 2 can be poured out through the pouring port 21 on the side wall away from the clamping component 4.
[0031] The ring 54 is designed to prevent the ball 53 from falling directly onto the annular ring seat 544 when it accidentally falls, thus avoiding the ball 53 falling onto the impact platform 2 and causing injury to personnel.
[0032] Example 2 Based on Example 1, such as Figure 1 , Figure 5As shown, the flip shaft 3 is rotatably set at the end of the impact table groove 11 away from the impact test steel ball assembly 5. When the glass panel impact test is completed and the glass panel breaks (at this time the broken glass panel is located inside the impact table 2), the impact table 2 can be flipped with the flip shaft 3 as the axis, so that the glass fragments inside the impact table 2 can be poured out through the pouring port 21 on the side wall of the impact table 2 away from the clamping assembly 4, which facilitates the cleaning of broken glass; at the same time, it is also convenient to continue to place new glass panels in the impact table 2 for continued testing, which improves the operating efficiency.
[0033] A baffle of a matching shape (not shown in the attached drawing) can also be movably installed on the pouring port 21 to reduce or prevent glass fragments from the glass panel from splashing out from the pouring port 21 during the test.
[0034] Example 3 Based on Example 1, such as Figure 1 , Figure 5 , Figure 8 As shown, a drive motor 6 is rotatably mounted on the top surface of the impact seat 1 near the impact table 2. A pressure shaft 61 is coaxially mounted on the output shaft of the drive motor 6. Multiple pressure plates 62, corresponding to the positions of the impact table 2, are mounted on the pressure shaft 61, and the pressure plates 62 abut against the opening on the top surface of the impact table 2. Before conducting an impact test on the glass panel, the impact table 2 is rotated about the flipping shaft 3 into the impact table groove 11. The glass panel is then placed horizontally in the opening on the top surface of the impact table 2. After the glass panel is fixed using the clamping assembly 4, the drive motor 6 is started to drive the pressure shaft 61 and the pressure plates 62 to rotate simultaneously, thereby allowing the pressure plates to rotate. The outer peripheral wall of the plate 62 abuts against the top opening of the impact table 2 (the plate 62 can be set as a peach-shaped plate structure, which makes it easy to use the large diameter end or the small diameter end of the plate 62 to abut against the top opening of the impact table 2 and to press and fix the impact table 2. At the same time, when the impact table 2 needs to be flipped, the small diameter end or the large diameter end of the plate 62 can be rotated to be offset from the position of the impact table 2), so that the impact table 2 can be pressed and fixed in the impact table groove 11; which makes it easy to keep the impact table 2 stable when the glass panel is subjected to impact test, that is, when the ball 53 falls onto the glass panel, the impact table 2 is prevented from shaking.
[0035] Example 4 Based on Example 1, such as Figures 1 to 4 As shown, the pressure plate 42 is provided with a stepped through groove 421 that matches the threaded rod 41. A stepped plate 422 that matches the stepped through groove 421 is rotatably provided on the threaded rod 41. The stepped plate 422 is movably disposed in the stepped through groove 421. The side wall of the pressure plate 42 near the bottom of the impact table 2 has an arc-shaped structure. The locking nut 43 abuts against the side wall of the impact table 2.
[0036] Before conducting the impact test on the glass panel, the impact table 2 is rotated around the rotating shaft 3 into the impact table groove 11. The glass panel is then placed horizontally in the opening on the top surface of the impact table 2. The threaded rod 41 is rotated so that the pressure plate 42 abuts against the top surface of the glass panel and simultaneously against the side wall of the impact table 2. The locking nut 43 is then tightened. At this point, the pressure plate 42, the stepped plate 422, and the locking nut 43 work together to clamp and fix the pressure plate 42, thereby pressing and fixing the glass panel. When testing glass panels of different thicknesses is required, the position of the pressure plate 42 can be adjusted (so that the stepped plate 422 can move within the stepped through groove 421 for position adjustment). The pressure plate 42 can be used to press and fix glass panels of different thicknesses, thereby improving the versatility of the test.
[0037] Example 5 Based on Example 1, such as Figure 1 , Figures 5 to 7 As shown, the test frame 51 is externally fitted with a movable sleeve 511. A lifting cylinder 512 is installed on the top surface of the impact seat 1. The piston rod of the lifting cylinder 512 is connected to the movable sleeve 511. A horizontal bar 513 is installed on the movable sleeve 511. A ball seat 514 is installed at the end of the horizontal bar 513 away from the movable sleeve 511. The bottom surface of the ball seat 514 is open. An electromagnet 52 is embedded in the top of the bottom opening of the ball seat 514. A ball 53 is movably installed in the bottom opening of the ball seat 514. The bottom opening of the ball seat 514 is circular, and the diameter of the bottom opening of the ball seat 514 is larger than the diameter of the ball 53. Before conducting the impact test on the glass panel, the impact table 2 is rotated into the impact table groove 11 around the flipping shaft 3. The glass panel is then placed... After being placed horizontally in the top opening of the impact table 2, the lifting cylinder 512 can be activated to drive the ball seat 514 to adjust its position in the vertical direction according to different test requirements, so that the ball 53 can fall from different heights and thus achieve different test effects. That is, before the test, the ball 53 is attracted to the electromagnet 52 (at this time, the ball 53 is located in the bottom opening of the ball seat 514), and the support ring 54 is located directly below the ball 53. During the test, the support ring 54 (circular support ring seat 544) is moved to a position that is offset from the ball 53, and the electromagnet 52 is turned off so that the ball 53 falls onto the glass panel. The test conclusion can be drawn based on the height from which the ball 53 falls from the test frame 51 and the damage to the glass panel.
[0038] Multiple adjusting threaded rods 515 are evenly distributed circumferentially on the outer peripheral wall of the ball seat 514. The adjusting threaded rods 515 move through the outer peripheral wall of the ball seat 514 to the bottom opening of the ball seat 514. Depending on the diameter of the ball 53 (i.e., when the diameter of the ball 53 is small), the length of the adjusting threaded rods 515 that pass through the bottom opening of the ball seat 514 can be adjusted by rotating the adjusting threaded rods 515. This helps to keep the ball 53 in the middle position of the bottom opening of the ball seat 514, making it easier to accurately grasp the position of the ball 53 when it falls, and also preventing the ball 53 from wobbling easily in the bottom opening of the ball seat 514.
[0039] Example 6 Based on Example 1, such as Figure 1 , Figures 5 to 7 As shown, the support ring 54 includes a rotating motor base 541, which is connected to the piston rod of the lifting cylinder 512; the rotating motor 542 is embedded inside the rotating motor base 541; the annular support ring seat 544 is horizontally connected to the output shaft of the rotating motor 542 via a connecting rod 543; the inner diameter of the annular support ring seat 544 is smaller than the diameter of the sphere 53, and the axis of the annular support ring seat 544 and the axis of the output shaft of the rotating motor 542 are both perpendicular to the horizontal plane.
[0040] Before conducting the impact test on the glass panel, the impact table 2 is rotated around the flipping shaft 3 into the impact table slot 11; the glass panel is placed horizontally in the top opening of the impact table 2; before the test, the ball 53 is attracted to the electromagnet 52 (at this time, the ball 53 is located in the bottom opening of the ball seat 514); at the same time, the rotating motor 542 is started to drive the connecting rod 543 and the annular support ring 544 to rotate towards a position close to the bottom of the ball 53. When the annular support ring 544 is directly below the ball 53, the test is complete. It can prevent the ball 53 from falling accidentally (when the ball 53 falls accidentally, it can fall directly onto the annular support 544, avoiding the ball 53 falling onto the impact table 2 and causing personnel injury); when conducting the test, the rotating motor 542 can be started to drive the connecting rod 543 and the annular support 544 to rotate away from the position below the ball 53 (so that the position of the annular support 544 is offset from the position below the ball 53). When the electromagnet 52 is turned off, the ball 53 can fall onto the glass panel to complete the test.
[0041] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
