Description

Technical Field

[0001] This utility model relates to the field of fiberglass testing technology, and in particular to a device for testing the performance of fiberglass composite panels. Background Technology

[0002] Fiberglass composite panels are high-performance materials made from glass fiber and resin matrix through a composite process. Their density is 1 / 4 to 1 / 5 that of steel. They are lightweight yet strong, have excellent impact resistance, and can resist corrosion from acids, alkalis, salt spray, and organic solvents. They also have good electrical insulation properties and are widely used in construction, transportation, chemical and other fields.

[0003] When producing fiberglass composite panels, it is necessary to perform performance testing on the finished products. During existing testing, some defective fiberglass panels will crack. In the next test, the cracked glass shards need to be cleaned up separately, but cleaning up the glass shards is troublesome and may also cause injury to workers. Therefore, this application provides a fiberglass composite panel performance testing device to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a performance testing device for fiberglass composite panels to solve the problem that some defective fiberglass panels will crack during testing. In the next test, the cracked glass fragments need to be cleaned up separately, but cleaning up the glass fragments is troublesome and may also cause injury to the staff.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A performance testing device for fiberglass composite panels includes a housing. A worktable with a sloping top is fixedly connected to the inner wall of the housing. A groove parallel to the sloping top of the worktable is formed on one side of the worktable. A motor is mounted on the top of the housing. A gear one is fixedly connected to the output end of the motor. Gears two and three are rotatably connected to the top of the housing, both meshing with gear one. Rotary rods penetrating the housing and the worktable are fixedly connected to the sides of gears two and three near the housing. The outer wall of the rotary rod is threaded inside the housing. A moving plate is helically connected between the threads. A testing mechanism is mounted at the bottom of the moving plate. A detection mechanism is mounted on the worktable. An adjustment mechanism for adjusting the size of the fiberglass sheet to be tested includes a first movable block located at the lower part of the worktable and a second movable block located at the higher part of the worktable. A slider is fixedly connected to one side of both the first and second movable blocks, and the slider is slidably connected to the slide groove. A rack is fixedly connected to the side of the first and second movable blocks that are close to each other. The racks on the first and second movable blocks are symmetrically arranged. Both the first and second movable blocks have through grooves that allow the racks to pass through. A fixed block is fixedly connected to one side of the second movable block. A retaining rod is rotatably connected to the top of the first movable block, and a rotating block for placing the fiberglass sheet to be tested is fixedly connected to one end of the retaining rod.

[0007] Preferably, a limiting pin is rotatably connected in the middle of the inner side of the slide groove, and a gear four is fixedly connected to the limiting pin and penetrated by the limiting pin. The rack on the first moving block and the rack on the second moving block both mesh with the gear four.

[0008] Preferably, the top of the movable block is fixedly connected to a limiting shell that can limit the rotation angle of the lever.

[0009] Preferably, the testing mechanism includes a pressure block fixedly connected to the bottom of the moving plate and located directly above the rotating block and the fixed block. The bottom of the pressure block is parallel to the top inclined surface of the workbench and is fixedly connected to a plurality of equally spaced support rods. The bottom of the support rods is fixedly connected to a strength testing head.

[0010] Preferably, a number of equally spaced protrusions are fixedly connected to the lower part of the top slope of the workbench.

[0011] Preferably, a housing is fixedly connected to one side of the box body, and a sliding rod 1 that penetrates the box body is fixedly connected to one side of the movable plate. The sliding rod 1 is slidably connected to the box body. The end of the sliding rod 1 away from the movable plate is located inside the housing and is rotatably connected to a transmission rod. The end of the transmission rod away from the sliding rod 1 is rotatably connected to a sliding rod 2. The end of the sliding rod 2 away from the transmission rod penetrates the box body and is slidably connected to the box body. The end of the sliding rod 2 located inside the box body is fixedly connected to a push block.

[0012] Preferably, a drawer is slidably connected to the bottom of the box, and the drawer has an opening on the side near the push block that allows the push block to move into the drawer.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects:

[0014] In the above scheme, by setting an adjustment mechanism, when inspecting the fiberglass sheet, one end of the limiting pin can be rotated first, causing the limiting pin to drive the gear four to rotate. This causes the racks on moving block one and moving block two to move in opposite directions, adjusting appropriately according to the size of the fiberglass sheet to be inspected. Then, the fiberglass sheet to be inspected is inserted between moving block one and moving block two to check the alignment of the two sides of the fiberglass sheet. If it can be inserted smoothly, it proves that the fiberglass sheet to be inspected is a qualified product with parallel alignment on both sides. If there is great resistance when inserting, it proves that the fiberglass sheet to be inspected is a defective product with insufficient alignment on both sides. After the two blocks are in place, the bottom of the fiberglass sheet to be inspected will be clamped by the rotating block and the fixed block. At this time, the motor is started, and the first gear rotates, which drives the second and third gears to rotate, thereby rotating the rotating rod. Through the thread, the moving plate moves towards the worktable, allowing the inspection mechanism on the moving plate to inspect the fiberglass sheet to be inspected. The advantage of this is that before inspection, the alignment of the two sides of the fiberglass sheet to be inspected can be judged by the first and second moving blocks, thereby screening out some defective products in terms of shape. Furthermore, by rotating the limit pin, the distance between the first and second moving blocks can be adjusted to change the inspectable size of the fiberglass sheet, thus accommodating the inspection of more fiberglass sheets.

[0015] By setting up a testing mechanism, as the moving plate moves closer to the worktable, it drives the pressure block to move, causing the strength testing head at the bottom of the support rod to gradually come into contact with the fiberglass sheet to be tested, applying pressure. If the fiberglass sheet is undamaged when a certain pressure value is reached, it indicates that the strength of the fiberglass sheet is qualified; if it breaks, it indicates that the strength of the fiberglass sheet is unqualified. Then, the motor is controlled to rotate in the opposite direction, which drives the rotating rods at the bottom of gears two and three to rotate in the opposite direction through gear one, causing the moving plate to move upward and reset. If the strength of the fiberglass sheet to be tested is unqualified... After the moving plate is reset, rotate the lever so that it contacts the inner top wall of the limiting shell. When the lever rotates, it will cause the rotating block to rotate upward. When the rotating block rotates upward, the glass fragments on the rotating block are no longer blocked by the rotating block. The glass fragments will slide down the inclined surface of the worktable. When they slide down, they will hit the protrusion and break the larger glass fragments into smaller pieces. The advantage of this is that there is no need to clean the glass fragments of defective products separately. After the inspection is completed, rotating the lever will cause the rotating block to rotate upward, allowing the glass fragments of defective products to slide directly down the inclined surface of the worktable, so as to quickly and safely clean up the glass fragments.

[0016] By setting up a push block, glass shards will fall onto the push block after sliding down the inclined surface of the workbench. When the moving plate moves closer to the workbench during the next detection, the moving plate will drive the slide rod one to slide on the cabinet. When slide rod one moves downward, the transmission rod will be forced to slide slide rod two towards the inside of the cabinet. When slide rod two slides, it will push the push block, which will push the glass shards into the inside of the drawer, preventing too much glass shards from clogging up. It also makes it easier to collect the glass shards. When cleaning is needed, simply pull out the drawer, which is convenient and quick. Attached Figure Description

According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0026] The performance testing device for fiberglass composite panels provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0027] like Figures 1-4As shown, an embodiment of this utility model provides a performance testing device for fiberglass composite panels, including a housing 1. A workbench 2 with a sloping top is fixedly connected to the inner wall of the housing 1. A groove 19 parallel to the sloping top of the workbench 2 is provided on one side of the workbench 2. A motor 5 is installed on the top of the housing 1. A gear 6 is fixedly connected to the output end of the motor 5. Gears 7 and 8 are rotatably connected to the top of the housing 1. Gears 7 and 8 mesh with gear 6. Rotating rods 9 that penetrate the housing 1 and the workbench 2 are fixedly connected to the side of gears 7 and 8 near the housing 1. The outer wall of the rotating rods 9 is provided with threads 10 inside the housing 1. The threads 10 are helically connected to the same moving plate 3. A testing mechanism is installed at the bottom of the moving plate 3. An adjustment mechanism 4 is installed on the workbench 2 to adjust according to the size of the fiberglass panel to be tested. The adjustment mechanism 4 includes a moving block located at the lower part of the workbench 2. 41 and 42 are located at a higher position on the workbench 2. A slider 48 is fixedly connected to one side of both the first and second movable blocks 41 and 42. The slider 48 is slidably connected to the slide groove 19. A rack 43 is fixedly connected to the side of the first and second movable blocks 41 that is close to each other. The rack 43 on the first and second movable blocks 41 are symmetrically arranged. A through groove 47 is opened on both the first and second movable blocks 41 to allow the rack 43 to pass through. A fixed block 45 is fixedly connected to one side of the second movable block 42. A retaining rod 46 is rotatably connected to the top of the first movable block 41. A rotating block 44 for placing the fiberglass plate to be tested is fixedly connected to one end of the retaining rod 46. A limiting pin 17 is rotatably connected in the middle of the slide groove 19. A gear 48 that is penetrated by the limiting pin 17 is fixedly connected to the limiting pin 17. The rack 43 on the first and second movable blocks 41 meshes with the gear 48.

[0028] By setting the adjustment mechanism 4, when inspecting the fiberglass sheet, one end of the limiting pin 17 can be rotated first, causing the limiting pin 17 to drive the gear 18 to rotate. This causes the rack 43 on the first moving block 41 and the rack 43 on the second moving block 42 to move in opposite directions, adjusting appropriately according to the size of the fiberglass sheet to be inspected. Then, the fiberglass sheet to be inspected is inserted between the first moving block 41 and the second moving block 42 to check the alignment of the two sides of the fiberglass sheet. If it can be inserted smoothly, it proves that the fiberglass sheet to be inspected is a qualified product with parallel alignment on both sides. If there is a large resistance when inserting it, it proves that the fiberglass sheet to be inspected is a defective product with insufficient alignment on both sides. After being inserted between the first moving block 41 and the second moving block 42... The bottom of the fiberglass sheet to be inspected is clamped by the rotating block 44 and the fixed block 45. At this time, the motor 5 is started, causing the gear 1 6 to rotate, which in turn drives the gear 2 7 and the gear 3 8 to rotate, thereby causing the rotating rod 9 to rotate. Through the thread 10, the moving plate 3 is moved towards the worktable 2, allowing the inspection mechanism on the moving plate 3 to inspect the fiberglass sheet to be inspected. The advantage of this is that before inspection, the alignment of the two sides of the fiberglass sheet to be inspected can be judged by the moving block 1 41 and the moving block 2 42, thereby screening out some defective products in terms of shape. Furthermore, by rotating the limit pin 17, the distance between the moving block 1 41 and the moving block 2 42 can be adjusted to change the inspectable size of the fiberglass sheet, thus accommodating the inspection of more fiberglass sheets.

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the top of the moving block 41 is fixedly connected to a limiting shell 49 that can limit the rotation angle of the lever 46. The detection mechanism includes a pressure block 21 fixedly connected to the bottom of the moving plate 3 and located directly above the rotating block 44 and the fixed block 45. The bottom of the pressure block 21 is parallel to the top slope of the workbench 2 and is fixedly connected to a plurality of equally spaced support rods 22. The bottom of the support rods 22 is fixedly connected to a strength detection head 23. A plurality of equally spaced protrusions 20 are fixedly connected to the lower part of the top slope of the workbench 2.

[0030] By setting up a testing mechanism, as the moving plate 3 moves closer to the worktable 2, it drives the pressure block 21 to move, causing the strength testing head 23 at the bottom of the support rod 22 to gradually come into contact with the fiberglass sheet to be tested, applying pressure to the sheet. If the sheet remains undamaged when a certain pressure value is reached, it indicates that the strength of the sheet is qualified. If it breaks, it indicates that the strength of the sheet is unqualified. Then, the motor 5 is controlled to rotate in the opposite direction, which drives the rotating rod 9 at the bottom of the gear 7 and gear 8 to rotate in the opposite direction through the gear 1 6, allowing the moving plate 3 to move upward and reset. If the strength of the sheet is unqualified, the moving plate 3 will be moved upward and reset. After plate 3 is reset, rotate lever 46 so that lever 46 abuts against the top inner wall of limit shell 49. When lever 46 rotates, it will drive rotating block 44 to rotate upward. When rotating block 44 rotates upward, the glass fragments on rotating block 44 are no longer blocked by rotating block 44. The glass fragments will slide down the inclined surface of worktable 2. When they slide down, they will hit protrusion 20 and break larger pieces of glass fragments into smaller pieces. The advantage of this is that it is not necessary to clean the glass fragments of defective products separately. After the inspection is completed, rotating lever 46 will drive rotating block 44 to rotate upward, allowing the glass fragments of defective products to slide directly down the inclined surface of worktable 2, so as to clean the glass fragments quickly and safely.

[0031] like Figure 1 As shown, a shell 11 is fixedly connected to one side of the box body 1, and a sliding rod 12 penetrating the box body 1 is fixedly connected to one side of the movable plate 3. The sliding rod 12 is slidably connected to the box body 1. The end of the sliding rod 12 away from the movable plate 3 is located inside the shell 11 and is rotatably connected to a transmission rod 13. The end of the transmission rod 13 away from the sliding rod 12 is rotatably connected to a sliding rod 14. The end of the sliding rod 14 away from the transmission rod 13 penetrates one side of the box body 1 and is slidably connected to the box body 1. The end of the sliding rod 14 located inside the box body 1 is fixedly connected to a push block 15. A drawer 16 is slidably connected to the bottom of the box body 1. An opening is provided on the side of the drawer 16 near the push block 15, allowing the push block 15 to move into the drawer 16.

[0032] By setting the push block 15, glass shards will fall onto the push block 15 after sliding out along the inclined surface of the workbench 2. When the moving plate 3 moves closer to the workbench 2 during the next detection, the moving plate 3 will drive the slide rod 12 to slide on the box 1. When the slide rod 12 moves downward, the transmission rod 13 will be forced to slide the slide rod 14 towards the inside of the box 1. When the slide rod 14 slides, it will push the push block 15, allowing the push block 15 to push the glass shards into the inside of the drawer 16, avoiding excessive glass shards from clogging together. It also facilitates the collection of glass shards. When cleaning is needed, simply pull out the drawer 16, which is convenient and quick.

[0033] The technical solution provided by this utility model, by setting an adjustment mechanism 4, allows for the following steps when inspecting a fiberglass sheet: First, one end of the limiting pin 17 can be rotated, causing the limiting pin 17 to drive the gear 4 18 to rotate. This causes the rack 43 on moving block 1 41 and the rack 43 on moving block 2 42 to move in opposite directions, adjusting appropriately according to the size of the fiberglass sheet to be inspected. Then, the fiberglass sheet to be inspected is inserted between moving block 1 41 and moving block 2 42 to check the alignment of the two sides. If it can be inserted smoothly, it proves that the fiberglass sheet to be inspected is a qualified product with parallel alignment on both sides. If there is significant resistance during insertion, it proves that the fiberglass sheet to be inspected is a defective product with insufficient alignment on both sides. After the two blocks 42 are positioned between the two sides, the bottom of the fiberglass plate to be inspected will be clamped by the rotating block 44 and the fixed block 45. At this time, the motor 5 is started, which makes the gear 6 rotate, driving the gear 7 and the gear 8 to rotate, thereby making the rotating rod 9 rotate. Through the thread 10, the moving plate 3 is moved towards the worktable 2, so that the inspection mechanism on the moving plate 3 can inspect the fiberglass plate to be inspected. The advantage of this is that before inspection, the alignment of the two sides of the fiberglass plate to be inspected can be judged by the moving blocks 41 and 42, thereby screening out some defective products in terms of shape. Furthermore, by rotating the limit pin 17, the distance between the moving blocks 41 and 42 can be adjusted to change the inspectable size of the fiberglass plate, thus accommodating the inspection of more fiberglass plates.

[0034] By setting up a testing mechanism, as the moving plate 3 moves closer to the worktable 2, it drives the pressure block 21 to move, causing the strength testing head 23 at the bottom of the support rod 22 to gradually come into contact with the fiberglass sheet to be tested, applying pressure to the sheet. If the sheet remains undamaged when a certain pressure value is reached, it indicates that the strength of the sheet is qualified. If it breaks, it indicates that the strength of the sheet is unqualified. Then, the motor 5 is controlled to rotate in the opposite direction, which drives the rotating rod 9 at the bottom of the gear 7 and gear 8 to rotate in the opposite direction through the gear 1 6, allowing the moving plate 3 to move upward and reset. If the strength of the sheet is unqualified, the moving plate 3 will be moved upward and reset. After plate 3 is reset, rotate lever 46 so that lever 46 abuts against the top inner wall of limit shell 49. When lever 46 rotates, it will drive rotating block 44 to rotate upward. When rotating block 44 rotates upward, the glass fragments on rotating block 44 are no longer blocked by rotating block 44. The glass fragments will slide down the inclined surface of worktable 2. When they slide down, they will hit protrusion 20 and break larger pieces of glass fragments into smaller pieces. The advantage of this is that it is not necessary to clean the glass fragments of defective products separately. After the inspection is completed, rotating lever 46 will drive rotating block 44 to rotate upward, allowing the glass fragments of defective products to slide directly down the inclined surface of worktable 2, so as to clean the glass fragments quickly and safely.

[0035] By setting the push block 15, glass shards will fall onto the push block 15 after sliding out along the inclined surface of the workbench 2. When the moving plate 3 moves closer to the workbench 2 during the next detection, the moving plate 3 will drive the slide rod 12 to slide on the box 1. When the slide rod 12 moves downward, the transmission rod 13 will be forced to slide the slide rod 14 towards the inside of the box 1. When the slide rod 14 slides, it will push the push block 15, allowing the push block 15 to push the glass shards into the inside of the drawer 16, avoiding excessive glass shards from clogging together. It also facilitates the collection of glass shards. When cleaning is needed, simply pull out the drawer 16, which is convenient and quick.
