Description

Technical Field

[0001] This utility model relates to the field of adhesive material performance testing technology, specifically, to an adhesive material shear performance testing fixture. Background Technology

[0002] Experimental studies on the shear properties of composite materials mainly employ methods such as the orbital shear method (including the double-orbit and triple-orbit shear methods), the Iosipescu shear method, and the V-notch orbital shear method. Among these, the Iosipescu shear method is widely used in the field of composite material shear property testing due to its simplicity, ease of operation, readily available V-notch beam specimens, and relatively ideal test results. It has also been established as the test standard ASTM D5379.

[0003] The utility model with publication number CN 216669511U discloses a fixture for testing the shear properties of composite materials, including an upper pressure block, a lower pressure block, a left wedge-shaped locking block, a right wedge-shaped locking block, a left fastening bolt, a right fastening bolt, a V-shaped notched beam specimen, an upper clamping bolt, a lower clamping bolt, an upper centering device, a lower centering device, an upper guide post, a lower guide post, an upper loading rod, and a lower loading rod.

[0004] In the aforementioned application, the cooperation between the upper and lower pressure block components makes it difficult to clean the material after testing in the fixture. This results in the need for manual cleaning of residual material after the test, which increases labor costs. Therefore, we propose a fixture for testing the shear properties of adhesive materials. Utility Model Content

[0005] This utility model proposes a fixture for testing the shear properties of adhesive materials.

[0006] The technical solution of this utility model is as follows: A shear performance testing fixture for adhesive materials includes a worktable, a support column fixedly connected to the bottom of the worktable, and an adjustment mechanism provided on the top of the worktable; the adjustment mechanism includes a bidirectional motor, the bottom of which is fixedly connected to the top of the worktable, a rotating shaft fixedly connected to the output shaft of the bidirectional motor, a threaded rod fixedly connected to the end of the rotating shaft away from the output shaft of the bidirectional motor, a threaded sleeve threadedly connected to the circumferential surface of the threaded rod, a connecting rod fixedly connected to the side of the threaded sleeve, a lower clamping plate fixedly connected to the end of the connecting rod away from the side of the threaded sleeve, a moving groove provided on the top of the worktable, the bottom of the lower clamping plate slidingly connected to the interior of the moving groove, a threaded adjusting rod fixedly connected to the top of the lower clamping plate, and an upper clamping plate threadedly connected to the circumferential surface of the threaded adjusting rod.

[0007] The threaded adjusting rod has an adjusting nut threadedly connected to its circumferential surface. The circumferential surface of the threaded rod is fixedly connected to a limiting plate. The function of the adjusting nut threadedly connected to the circumferential surface of the threaded adjusting rod is to clamp and adjust the upper clamping plate through the threaded adjusting rod by adjusting the adjusting nut. The function of the limiting plate fixedly connected to the circumferential surface of the threaded rod is to limit the movement distance of the threaded sleeve.

[0008] The bidirectional motor has a limiting shaft fixedly connected to its side. The circumferential surface of the limiting shaft penetrates the side of the threaded sleeve and is slidably connected to the side of the threaded sleeve. The function of the limiting shaft in penetrating the side of the threaded sleeve and slidingly connecting to the side of the threaded sleeve is to prevent the threaded sleeve from rotating during movement.

[0009] The number of threaded sleeves, lower clamping plates, and upper clamping plates is set to two, and they are symmetrical to each other along the vertical central axis of the worktable. Their function is to double-clamp the material through the two lower clamping plates and the upper clamping plate.

[0010] The top of the workbench is equipped with a cleaning mechanism, which includes a gear. The side of the gear is fixedly connected to the circumferential surface of the rotating shaft. A sliding groove is formed on the top of the workbench, and a sliding column is slidably connected inside the sliding groove. A rack is fixedly connected to the end of the sliding column away from the inside of the sliding groove. A moving rod is fixedly connected to the side of the rack, and a cleaning brush is fixedly connected to the end of the moving rod away from the side of the rack. The top of the workbench has a cleaning groove. The function of the cleaning mechanism on the top of the workbench is to clean the residual material on the top of the workbench after the material test is completed.

[0011] The cleaning tank has a cleaning port inside, and a support plate is fixedly connected to the top of the workbench. A collection box is slidably connected to the side of the support plate. The purpose of the cleaning port inside the cleaning tank is to allow the cleaned material to leave the cleaning tank through the cleaning port, and the purpose of the collection box slidably connected to the side of the support plate is to collect the cleaned material through the collection box.

[0012] The bottom of the cleaning brush contacts the inner wall of the cleaning tank, and the top of the collection box is located directly below the cleaning opening. The bottom of the cleaning brush contacts the inner wall of the cleaning tank to ensure that the cleaning brush can accurately remove the material inside the cleaning tank when it moves. The top of the collection box is located directly below the cleaning opening to ensure that the material can accurately fall into the collection box through the cleaning opening.

[0013] The circumferential surface of the gear meshes with the side surface of the rack. The purpose of this meshing is to ensure that the gear can drive the rack to move when it rotates.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. This utility model utilizes the interoperability of components such as the bidirectional motor, upper clamping plate, and threaded adjustment rod of the adjustment mechanism. When shear performance testing of adhesive materials is required, the operator first starts the bidirectional motor to expand the threaded sleeve outward, causing the lower clamping plate to move inside the moving groove. At this time, the operator adjusts the width to an appropriate size based on the size of the adhesive material. After adjustment, the operator places the adhesive material inside the lower clamping plate and then tightens the adjusting nut to adjust the upper clamping plate through the threaded adjustment rod, so that the upper clamping plate tightly fixes the adhesive material on the lower clamping plate. This design achieves the effect of adjusting the width of the clamping component, effectively improving the flexibility of the clamping component.

[0016] 2. This utility model utilizes the interplay between components such as gears, racks, and cleaning brushes in the cleaning mechanism. After the adhesive material test is completed, residual adhesive material accumulates inside the cleaning tank on the workbench. At this point, the operator can activate the bidirectional motor, which, through the meshing of the gears and rack, moves the rack from right to left, thereby driving the cleaning brush to move from right to left via a moving rod. During the right-to-left movement, the cleaning brush cleans the residual adhesive material inside the cleaning tank. The cleaned adhesive material falls into the collection box through the cleaning port. This design achieves the effect of cleaning the workbench after testing, effectively preventing excessive residual material accumulation on the workbench surface from affecting the next test, while also reducing manual labor.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-5As shown, this embodiment proposes a shear performance testing fixture for adhesive materials, including a workbench 1. A support column 2 is fixedly connected to the bottom of the workbench 1, and an adjustment mechanism 3 is provided on the top of the workbench 1. The adjustment mechanism 3 includes a bidirectional motor 31, the bottom of which is fixedly connected to the top of the workbench 1. A rotating shaft 32 is fixedly connected to the output shaft of the bidirectional motor 31. A threaded rod 33 is fixedly connected to the end of the rotating shaft 32 away from the output shaft of the bidirectional motor 31. A threaded sleeve 34 is threadedly connected to the circumferential surface of the threaded rod 33. A connecting rod 35 is fixedly connected to the side of the threaded sleeve 34. A lower clamping plate 36 is fixedly connected to the end of the connecting rod 35 away from the side of the threaded sleeve 34. A moving groove 37 is provided on the top of the workbench 1. The bottom of the lower clamping plate 36 is slidably connected to the interior of the moving groove 37. A threaded adjusting rod 38 is fixedly connected to the top of the lower clamping plate 36. An upper clamping plate 39 is threadedly connected to the circumferential surface of the threaded adjusting rod 38. An adjusting screw is threadedly connected to the circumferential surface of the threaded adjusting rod 38. The circumferential surface of the threaded rod 33 is fixedly connected to the limiting plate 311. The circumferential surface of the threaded adjusting rod 38 is threadedly connected to the adjusting nut 310. The function of the adjusting nut 310 is to clamp and adjust the upper clamping plate 39 through the threaded adjusting rod 38. The circumferential surface of the threaded rod 33 is fixedly connected to the limiting plate 311 to limit the movement distance of the threaded sleeve 34. The side of the bidirectional motor 31 is fixedly connected to the limiting shaft 312. The circumferential surface of the limiting shaft 312 passes through the side of the threaded sleeve 34 and is slidably connected to the side of the threaded sleeve 34. The function of the limiting shaft 312 is to prevent the threaded sleeve 34 from rotating during movement. The number of threaded sleeve 34, lower clamping plate 36 and upper clamping plate 39 is set to two, and they are symmetrical about each other along the vertical central axis of the worktable 1. The function is to double clamp the material through the two lower clamping plates 36 and the upper clamping plate 39.

[0028] In this embodiment, when it is necessary to test the shear performance of the adhesive material, the operator first starts the bidirectional motor 31. The output shaft of the bidirectional motor 31 rotates clockwise, which drives the rotating shaft 32 to rotate clockwise. The rotating shaft 32 rotates clockwise, which drives the threaded rod 33 to rotate clockwise. The threaded sleeve 34, which is threaded to the circumferential surface of the threaded rod 33, expands outward. The threaded sleeve 34 moves away from the bidirectional motor 31 and drives the lower clamping plate 36 to move inside the moving groove 37 through the connecting rod 35. At this time, the operator adjusts the adhesive material to an appropriate width according to its size. After adjustment, the operator places the adhesive material inside the lower clamping plate 36. After placement, the operator tightens the adjusting nut 310 to adjust the upper clamping plate 39 through the threaded adjusting rod 38, so that the upper clamping plate 39 tightly fixes the adhesive material on the lower clamping plate 36. After the preparation is completed, the adhesive material is tested.

[0029] Example 2

[0030] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the top of the workbench 1 is provided with a cleaning mechanism 4. The cleaning mechanism 4 includes a gear 41, the side of which is fixedly connected to the circumferential surface of the rotating shaft 32. A sliding groove 42 is opened on the top of the workbench 1. A sliding column 43 is slidably connected inside the sliding groove 42. A rack 44 is fixedly connected to one end of the sliding column 43 away from the inside of the sliding groove 42. A moving rod 45 is fixedly connected to the side of the rack 44. A cleaning brush 46 is fixedly connected to one end of the moving rod 45 away from the side of the rack 44. A cleaning groove 47 is opened on the top of the workbench 1. The function of the cleaning mechanism 4 on the top of the workbench 1 is to clean the material remaining on the top of the workbench 1 after the material test is completed. A cleaning port 48 is opened inside the cleaning groove 47. A support plate 49 is fixedly connected to the top of the workbench 1. A collection box 410 is slidably connected to the side of the support plate 49. The cleaning tank 47 has a cleaning port 48 inside, which allows the cleaned material to leave the cleaning tank 47. The support plate 49 has a collection box 410 slidably connected to its side, which collects the cleaned material. The bottom of the cleaning brush 46 is in contact with the inner wall of the cleaning tank 47, and the top of the collection box 410 is located directly below the cleaning port 48. The bottom of the cleaning brush 46 is in contact with the inner wall of the cleaning tank 47 to ensure that the cleaning brush 46 can accurately remove the material inside the cleaning tank 47 when it moves. The top of the collection box 410 is located directly below the cleaning port 48 to ensure that the material can accurately fall into the collection box 410 through the cleaning port 48. The circumferential surface of the gear 41 meshes with the side of the rack 44. The meshing of the circumferential surface of the gear 41 with the side of the rack 44 ensures that the gear 41 can drive the rack 44 to move when it rotates.

[0031] In this embodiment, after the adhesive material test is completed, residual adhesive material accumulates inside the cleaning tank 47 on the workbench 1. At this time, the operator can start the bidirectional motor 31. The output shaft of the bidirectional motor 31 rotates clockwise, which drives the rotating shaft 32 to rotate clockwise. The gear 41, which is fixed to the circumference of the rotating shaft 32, rotates clockwise along with the rotating shaft 32. Because the gear 41 and the rack 44 mesh with each other, the clockwise rotation of the gear 41 drives the rack 44 to move from right to left inside the slide groove 42 through the sliding column 43. The movement of the rack 44 from right to left drives the cleaning brush 46 to move from right to left through the moving rod 45. During the movement of the cleaning brush 46 from right to left, the residual adhesive material inside the cleaning tank 47 is cleaned. The adhesive material cleaned by the cleaning brush 46 falls into the collection box 410 through the cleaning port 48.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
