Description

Technical Field

[0001] The present invention relates to the technical field of pulling test, and more particularly to an adjustable automatic pulling test device. Background Art

[0002] Pull-out tests are usually conducted by applying pressure to test the adhesion between two objects or the strength of the object itself. Different pull-out equipment is required for testing different objects.

[0003] Testing is a measurement with experimental nature, that is, a combination of measurement and experiment. The means of testing is instruments. Since testing and measurement are closely related, they are often not strictly distinguished in actual use. The basic task of testing is to obtain useful information. By using special instruments and equipment, designing reasonable experimental methods, and performing necessary signal analysis and data processing, information related to the object being tested can be obtained. The final result of the test is to input the displayed information into the information processing library for control.

[0004] The most common method to evaluate the quality of bonding is to measure the bonding strength. Strength data is often required to characterize the performance of adhesives. Bonding strength is an important indicator in adhesive technology. It is very instructive for selecting adhesives, developing new adhesives, designing joints, improving bonding processes, and correctly applying adhesive structures. Bonding strength refers to the stress required to cause the interface between the adhesive and the adherend in the adhesive part or its vicinity to be destroyed under the action of external force. Bonding strength is also called bonding strength.

[0005] Bond strength is the stress required for the adhesive system to break. Its magnitude depends not only on the bonding force, the mechanical properties of the adhesive, the nature of the adherend, and the bonding process, but also on the joint form, stress conditions (type, size, direction, frequency), environmental factors (temperature, humidity, pressure, medium), test conditions, experimental technology, etc. It can be seen that bonding force is only one of the important factors that determine bonding strength, so bonding strength and bonding force are two completely different concepts and must not be confused.

[0006] The decorative materials on the wall surface, such as decorative panels or wallpaper, are partially bonded. When it is necessary to hang items on the decorative panels or wallpaper surface, the bonding performance between the wallpaper or decorative panels and the wall becomes particularly important. Therefore, relevant personnel need to have a clear understanding of the bonding strength. Therefore, it is necessary to perform a pull-out test between the wallpaper or decorative panels and the wall. Materials such as asphalt and glue need to test their bonding strength to judge the performance of the glue itself, or the bonding of asphalt to the cement pavement. Therefore, a pull-out test is also required. Even after welding is completed, whether the welding effect between different parts is good, whether there is a cold weld or a loose weld, so a pulling device is also required to judge the welding effect.

[0007] For example, a Chinese patent (application number: CN104655563A) discloses a pull-out test device, including a frame, a base, a jack, a truss, a force multiplier and a tension sensor, wherein the base is located in the frame, the top rod of the jack is connected to the crossbeam of the frame, the lower part of the truss is connected to one end of the force multiplier, the other end of the force multiplier is connected to the base seat through the tension sensor, and the tension sensor is connected to the data acquisition device. The present invention has a simple structure, is easy to operate, is less affected by external conditions, and can conveniently, quickly and accurately complete the pull-out test of the bonding force between the thermal insulation layer of the wall and the wall matrix.

[0008] However, it is difficult to adjust the direction of the applied pulling force, and the pulling force applied is mostly in a single fixed direction. If the object is pulled obliquely during actual use, the object cannot fully simulate its use environment during the pulling test, resulting in obvious limitations and deficiencies in the pulling test. At the same time, when the adhesion performance between objects is pulled out, dust may exist on the surface of the object, which will affect the connection between it and the pulling test device. Even the connection between the pulling device and the object to be tested is achieved through glue during the pulling process, and it may be difficult to remove the glue after it solidifies. Therefore, an adjustable automatic pulling test device is needed to solve the above problems. Summary of the invention

At the same time, when the first driving component 12 stops working, the self-locking function of the first driving component 12 can position the first gear 10 and the connecting tube 9 to avoid the electric hydraulic rod 13 from rotating randomly. The lower surface of the connecting tube 9 is fixedly connected to the top of the electric hydraulic rod 13.

[0033] The bottom end of the electric hydraulic rod 13 is fixedly connected to the upper surface of the force measuring assembly 14. By setting the electric hydraulic rod 13, the electric hydraulic rod 13 can be extended and shortened to adjust the positions of the connecting mesh plate 20, the suction cup 22 and the glue coating cylinder 23.

The lower surface of the force measuring assembly 14 is fixedly connected to the upper surface of the ball joint head 17. By setting a force measuring component 14, the force measuring component 14 is used to connect the electric hydraulic rod 13 and the connecting mesh plate 20.

The outer surface of the ball hinge shell 18 is provided with a connecting frame 19, and the lower surface of the connecting frame 19 is fixedly connected to the upper surface of the connecting mesh plate 20. The lower surface of the connecting mesh plate 20 is provided with four suction cups 22.

The lower surface of the connecting mesh plate 20 is clamped with a glue coating cylinder 23, and the lower surface of the inner wall of the glue coating cylinder 23 is provided with a connecting hole 24. By setting the glue coating cylinder 23, when the surface of the object to be tested is an uneven surface, after the glue is injected into the glue coating cylinder 23, the glue passes downward through the connecting hole 24 and contacts the surface of the object to be tested, thereby achieving the connection between the glue coating cylinder 23 and the object to be tested. The front and back sides of the connecting mesh plate 20 are provided with guide grooves 26.

[0034] The inner wall of the guide groove 26 is slidably connected with the outer surface of the guide block 27. By setting the guide groove 26 and the guide block 27, it is convenient to control the connecting rod 29 and the cleaning roller 30 to move left and right along the guide groove 26, so as to control the cleaning roller 30 to move to clean the surface of the object to be tested. The opposite sides of the two guide blocks 27 are provided with second bearings 28. By setting the second bearings 28 and the connecting rods 29, the second bearings 28 and the connecting rods 29 are interference fit. The connecting rod 29 will only rotate when it is rotated by the staff, so as to avoid the connecting rod 29 and the cleaning roller 30 from rotating randomly, so as to ensure that the connecting rod 29 and the cleaning roller 30 can be controlled by people, so as to facilitate the cleaning process of the cleaning roller 30 contacting with the surface of the object to be tested. At the same time, after the cleaning is completed, the cleaning roller 30 and the connecting rod 29 are controlled to rotate, so as to realize the storage of the cleaning roller 30. The inner walls of the two second bearings 28 are provided with connecting rods 29, and the opposite ends of the two connecting rods 29 are respectively fixedly connected with the front and back sides of the cleaning roller 30. The upper surface of the bottom plate 1 is fixedly connected with the lower surfaces of the two support plates 38. The opposite surfaces of the two support plates 38 are provided with clamping assemblies 39. By providing the clamping assemblies 39, the clamping assemblies 39 can clamp and place the sample-type test object. When the test object needs to be pulled out in the up and down directions, the object can be clamped and positioned. The opposite surfaces of the two vertical frames 2 are provided with connecting grooves 31. The upper surface of the vertical frame 2 is provided with a second driving assembly 36. By providing the second driving assembly 36, the screw rod 34 and the connecting nut 35, the second driving assembly 36 rotates while controlling the screw rod 34 to rotate. At this time, the screw rod The threaded action between 34 and the connecting nut 35 can control the movement of the connecting nut 35 to adjust the height of the cross bar 6 and the first drive assembly 12. In cooperation with the electric hydraulic rod 13 and the first drive assembly 12, the connecting mesh plate 20 and the suction cup 22 can be controlled to move to various heights and angles. The output shaft of the second drive assembly 36 is fixedly connected to the top of the screw rod 34, and the outer surface of the screw rod 34 is threadedly connected to the inner wall of the connecting nut 35. The opposite surfaces of the two connecting nuts 35 are respectively fixedly connected to the opposite back surfaces of the two connecting blocks 5.

[0035] like Figure 1 As shown, the front and back sides of the bottom plate 1 are fixedly connected to the opposite sides of four connecting plates 8 respectively. By providing the connecting plates 8, it is convenient for the staff to assemble the device, and the working process of the device is made more stable. A middle hole 37 is opened on the upper surface of the bottom plate 1, and the position of the middle hole 37 corresponds to the position of the connecting mesh plate 20.

[0036] like Figure 2 and Figure 4As shown, the upper surface of the bottom plate 1 is fixedly connected to the lower surfaces of the two storage frames 33. By setting the storage frames 33, the storage frames 33 are used to store the items and tools carried by the staff, which is convenient for the staff to take and put and the work process.

The third bearing 32 is provided on the lower surface of the inner wall of the connecting groove 31, and the opposite surfaces of the two vertical frames 2 are fixedly connected to the left and right side surfaces of the top frame 3 respectively.

[0037] like Figure 6 , Figure 7 and Figure 8 As shown, the guide block 27 is set to be rectangular, the shape of the guide groove 26 is adapted to the shape of the guide block 27, and a sealing cover 21 is set on the upper surface of the connecting frame 19. By setting the sealing cover 21, the staff can add glue to the inside of the glue coating cylinder 23 and clean the glue coating cylinder 23 through the sealing cover 21. A heating tube 25 is set on the inner wall of the glue coating cylinder 23. By setting the heating tube 25, the glue inside the glue coating cylinder 23 can be heated when the heating tube 25 is working. Since the glue has hot melt properties, after completing the pull-out test, the glue is melted, and the connection between the object to be tested and the device is released, thereby avoiding damage caused by pulling and disconnecting the glue connection.

[0038] like Figure 2 and Figure 3 As shown, the upper surface of the connecting frame 19 is connected with the bottom end of the connecting tube 16. By setting the connecting tube 16, the connecting tube 16 can realize the connection between the vacuum pump assembly 15 and the connecting frame 19, and the connecting tube 16 adopts a hose. When the positions of the connecting frame 19 and the suction cup 22 change, the connecting tube 16 can be deformed, while maintaining the connection between the vacuum pump and the connecting frame 19, to ensure that the suction inside the suction cup 22 is smoothly evacuated to create a negative pressure environment. The top of the connecting tube 16 is connected with the lower surface of the vacuum pump assembly 15, and the upper surface of the vacuum pump assembly 15 is fixedly connected to the lower surface of the cross bar 6. The back side of the first gear 10 on the right side is meshed with the front side of the second gear 11, and the right side of the second gear 11 is fixedly connected to the output shaft of the first drive assembly 12, and the front side of the first drive assembly 12 is fixedly connected to the back side of the cross bar 6.

[0039] like Figure 5As shown, the suction cup 22 is connected to the connecting mesh plate 20. By setting the connecting mesh plate 20 and the suction cup 22, the number of the suction cups 22 is four. The vacuum pump assembly 15 can simultaneously extract gas from the inside of the four suction cups 22 through the connecting pipe 16 and the connecting mesh plate 20, ensuring that the adsorption connection of the four suction cups 22 to the surface of the object to be tested is more stable and comprehensive. The connecting mesh plate 20 is connected to the connecting pipe 16 through the connecting frame 19, and the positions of the two clamping assemblies 39 correspond to each other.

[0040] Working principle of the present invention: when the device needs to be used, the second drive assembly 36 is directly controlled to work, at which time the second drive assembly 36 drives the screw rod 34 to rotate, and the threaded action between the screw rod 34 and the connecting nut 35 controls the connecting nut 35 and the moving block to move upward, and the connecting block 5 and the connecting tube 9 move upward. At this time, the electric hydraulic rod 13 drives the connecting mesh plate 20 and the suction cup 22 to move upward. When the suction cup 22 moves to a suitable position, the second drive assembly 36 is directly controlled to stop working, and then the first drive assembly 12 drives the second gear 11 to rotate. At this time, the second gear 11 drives the first gear 10 and the connecting tube 9 to rotate, and at the same time the electric hydraulic rod 13 rotates upward. When the electric hydraulic rod 13 rotates to a suitable angle, the second drive assembly 36 is controlled to stop. The work is stopped, and then the connecting rod 29 and the cleaning roller 30 are controlled to rotate downward by ninety degrees. Subsequently, the electric hydraulic rod 13 is controlled to drive the suction cup 22 to move until the cleaning roller 30 contacts the surface of the object to be tested. At this time, the cleaning roller 30 and the guide block 27 are controlled to move, and the cleaning roller 30 cleans the debris and dust on the surface of the object to be tested. When the dust is cleaned, the connecting rod 29 is directly controlled to rotate ninety degrees. When the cleaning roller 30 is separated from the object to be tested, the electric hydraulic rod 13 is controlled to drive the suction cup 22 to contact the object to be tested, and then the vacuum pump assembly 15 works. At this time, the vacuum pump assembly 15 draws vacuum from the inside of the suction cup 22, and the suction cup 22 is tightly adsorbed on the surface of the object to be tested. Subsequently, the electric hydraulic rod 13 is controlled to shorten. At this time, the pulling process can be observed through the force measuring assembly 14.

[0041] In summary, in the present invention:

[0042] The present invention is provided with a first driving assembly 12, a second driving assembly 36, a screw 34, a connecting tube 9, a connecting nut 35, a cross bar 6, a first gear 10, a second gear 11, an electric hydraulic rod 13, a force measuring assembly 14, a suction cup 22, a vacuum pump assembly 15 and a glue coating tube 23. If the surface of the object to be measured is smooth, the second driving assembly 36 is directly controlled to drive the screw 34 to rotate. At this time, the screw 34 drives the connecting nut 35 and the cross bar 6 to move downward, and at the same time, the cross bar 6 drives the suction cup 22 to move downward. When the suction cup 22 moves to a suitable position, the first driving assembly 12 is controlled to rotate. The first driving assembly 12 drives the second gear 11 to control the first gear 10 and the connecting tube 9 to rotate. At this time, the electric hydraulic rod 13 and the suction cup 22 rotate upward. When the electric hydraulic rod 13 rotates to a suitable angle, the suction cup 22 and the connecting mesh plate 20 are controlled to rotate to the corresponding surface angle of the object to be measured, and then the electric hydraulic rod 13 is controlled. The suction cup 22 is driven to move to contact the surface of the object to be tested, and then the vacuum pump component 15 is controlled to work. At this time, the vacuum pump component 15 drives the suction of the air inside the suction cup 22, and at the same time, the suction cup 22 is adsorbed on the surface of the object to be tested by the negative pressure environment. Then the electric hydraulic rod 13 is controlled to shorten. At this time, the mesh plate 20 and the suction cup 22 are connected to pull the object, and the test result can be read through the force measuring component 14. The device can adjust the angles of the suction cup 22 and the electric hydraulic rod 13 according to the different objects to be tested, and can apply pulling forces at different angles to achieve pulling tests on the object to be tested at multiple angles. It can be used for the pull-out test of the surface of the physical object while the sample of the object to be tested is directly placed on the surface of the bottom plate 1 for testing. The connection method of the suction cup 22 or glue bonding can be selected according to the situation of the surface of the object, so that the flexibility of the device is more ideal, and it can be applied to pull-out tests at different angles and on different surfaces of objects to be tested, and the application range is wider.

[0043] The present invention adopts a guide block 27, a guide groove 26, a second bearing 28 and a cleaning roller 30. The second bearing 28 and the connecting rod 29 are interference fit, so the connecting rod 29 and the cleaning roller 30 can be kept in a certain position and will not swing at will. Before connecting the device to the object to be tested, the connecting rod 29 and the cleaning roller 30 are controlled to rotate downward by ninety degrees, and then the guide block 27 is controlled to slide to the left in the guide groove 26. The cleaning roller 30 first contacts the connection between the object to be tested and the device, and cleans it, thereby reducing the influence of debris on the detection result and ensuring the stability of the connection between the object to be tested and the device.

[0044] The present invention adopts a clamping component 39 and a middle hole 37. The clamping component 39 can clamp and position the object to be tested when it is a sample, or directly place the object to be tested on top of the object to be tested when it needs to be pulled up and down. At the same time, when the object to be tested needs to be pulled forward and backward, the suction cup 22 can be controlled to rotate for adsorption testing, so that the flexibility and scope of use of the device are relatively ideal, and it has obvious economic value and promotion value.
