Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical testing, in particular to a horizontal tensile mechanical testing machine system. Background Art

[0002] Material mechanical property test is a test to determine the tensile, compression, bending and other characteristics of materials. Traditional material performance tests are usually carried out on large testing machines. The material is tested from the initial stress to being broken or peeled off, and a stress-strain curve is given, or the peel strength is recorded when the peeling force is stable.

[0003] In the related art, when testing the peel strength of a material tape or adhesive tape, a material tray of the material tape is usually placed on a driving mechanism, the ends of the material tape are fixed, and then the driving mechanism drives the material tray to move, thereby testing the peel strength of the material tape.

[0004] Many commonly used furniture are assembled from different boards, rather than cut into pieces. This is because a large number of board scraps can be re-used by assembly, effectively reducing board waste. Whether the assembled boards meet the actual requirements requires mechanical performance testing. Assembled boards that do not meet the mechanical requirements cannot be used in real life, otherwise serious accidents will occur.

[0005] At present, the tensile mechanical properties of conventional assembled panels, such as the locking force performance test of the floor, are tested in accordance with the national standard GB / T18102-2020. The locking force, that is, the tensile force test, is the maximum tensile force that the assembled specimen is initially subjected to by applying a tensile load. This has an important impact on the evaluation of the performance of the assembled panels.

[0006] However, the plate tensile mechanical properties testing equipment in the prior art has been greatly limited in its promotion and application due to a series of problems such as poor testing accuracy, small load input, poor stability, and poor impact resistance. It is urgent to make technical improvements to the existing equipment in order to obtain a high-quality tensile mechanical testing machine with good automation and intelligence, higher testing accuracy, and better use effect.

By applying tensile force on a horizontal plane, the maximum tensile force that various assemblies can withstand is tested, and the horizontal tensile mechanical performance test data thereof is obtained, so as to evaluate the horizontal tensile mechanical performance of the assemblies. The tensile effect in the vertical to horizontal direction is realized through dual synchronous stepping lifting drive combined with a simple chain structure transmission, so as to realize the automation and intelligent control of the whole system, significantly improve the testing efficiency of the system, greatly reduce the consumption of manpower and material resources, realize the available load of 0-1000N, and effectively expand the scope of use of the system.

[0042] During operation, the furniture board, wooden board, floor and other test pieces that need to be tested for horizontal tensile mechanical properties are assembled first, and one end of the test piece is mounted on the test machine fixed clamp 23 on the test machine fixed clamp mounting seat 22, and the other end is mounted on the test machine movable clamp mounting seat 34 and mounted on the test machine movable clamp 30, and the test machine fixed clamp 23 and the test machine movable clamp 30 are tightened by the movable clamp plate tightening knob 24 through the test machine fixed clamp 23 and the test machine movable clamp 30 and the test machine movable extrusion plate 25, so that the test piece is firmly fixed between the test machine fixed clamp 23 and the test machine movable clamp 30;

[0043] The movable clamp sensor connector 31, the horizontal tensile force sensor 32, and the sensor tensile connector 33 are installed and connected through the sensor connector screw group 43 and the tensile connector screw group 42 respectively, and the horizontal tensile chain 27 is installed and connected with the sensor tensile connector 33 through the horizontal tensile chain connector 37, and the horizontal tensile force sensor 32 on one side of the sensor tensile connector 33 is adjusted by rotating the connector horizontal adjustment knob 36 to keep the horizontality of the horizontal tensile chain connector 37 and the horizontal tensile chain 27 consistent;

[0044] The horizontal stretch chain 27 is extended into the L-shaped transmission chain frame 20 of the testing machine, and the horizontal stretch chain 27 is turned from horizontal to vertical upward through the first stretch chain transmission gear 28 at the lower end thereof, and rises to a certain position along the L-shaped transmission chain frame 20 of the testing machine, and is restored to a horizontal position and extended back through the second stretch chain transmission gear 28, and then passes through the third stretch chain transmission gear 28 at the top of the L-shaped transmission chain frame 20 of the testing machine;

[0045] The horizontal stretching chain 27 is turned from horizontal to vertical upward again, and the vertical stretching chain connector 13 is inserted into the primary stretching installation connector 10 through the primary installation connector pin to realize the installation connection of the vertical stretching chain connector 13 and the primary stretching installation connector 10, and the primary stretching installation connector 10 is inserted into the secondary stretching installation connector 8 through the secondary installation connector pin 9 to realize the installation connection of the primary stretching installation connector 10 and the secondary stretching installation connector 8, and finally the secondary stretching installation connector 8 is fixedly installed on the stretching lifting platform 4 of the testing machine to realize the installation connection of the overall structure;

[0046] Press the test machine control button 14 to start the data acquisition and analysis system 15. At this time, the data acquisition and analysis system 15 can also be a PC data acquisition and analysis control terminal or a mobile data acquisition and analysis control terminal. The horizontal tensile mechanical testing machine system works as a whole, and the dual synchronous lifting stepper motor 6 located in the test machine screw lifting support column 3 is started to realize the synchronous stepping rotation of the dual synchronous lifting stepper motor 6 in the test machine screw lifting support column 3 located on both sides of the mechanical testing machine body 1, thereby driving the lifting stepping rotating screw 5 installed and connected with the dual synchronous lifting stepper motor 6 to perform stepping rotation. Since the lifting stepping traction screw sleeve platform 7 integrally connected with the test machine tensile lifting platform 4 is threadedly engaged with the lifting stepping rotating screw 5, when the lifting stepping traction screw sleeve platform 7 is restricted by the fixed sliding sleeve rod in the test machine screw lifting support column 3, the stepping rotation of the lifting stepping rotating screw 5 will cause the lifting stepping traction screw sleeve platform 7 to move up and down;

[0047] Then, the data acquisition and analysis system 15 is used to precisely control the lifting stepping rotating screw 5 and the dual synchronous lifting stepping motor 6 in the screw lifting support column 3 of the testing machine, thereby precisely controlling the lifting and lowering of the screw lifting support column 3 of the testing machine, and precisely controlling the lifting and lowering of the tensile lifting platform 4 of the testing machine between the screw lifting support columns 3 of the testing machine;

[0048] As the tensile lifting platform 4 of the testing machine moves vertically upward, the secondary tensile installation connector 8, the primary tensile installation connector 10 and the vertical tensile chain connector 13 are pulled upward, and the tensile force is horizontally applied to the sensor tensile connector 33 through the testing machine L-shaped transmission chain frame 20 and the horizontal tensile chain 27. The horizontal tensile force transmitted by the sensor tensile connector 33 acts on the horizontal tensile force sensor 32, and further acts horizontally on the movable clamp sensor connector 31, and finally acts on the testing machine movable clamp 30, driving the testing machine movable clamp 30 to generate a horizontal tensile force on the test piece.

[0049] When the tensile force reaches a certain critical degree, the test piece is subjected to the maximum tensile force and breaks or separates. At this time, the horizontal tensile force sensor 32 obtains a maximum tensile force critical value, and transmits the data information to the data acquisition and analysis system 15 through the sensor data connector 40 and the data transmission wire 11. At this time, the dual synchronous stepping driving force data information generated by the tensile lifting platform 4 of the test machine will also be transmitted to the data acquisition and analysis system 15 through the data transmission wire 11. The data acquisition and analysis system 15 performs data acquisition and analysis, and the above operation is repeated to obtain multiple test data;

[0050] After the test is completed, stop the entire horizontal tensile mechanical testing machine system and cut off the power supply, and disassemble and place all components.

[0051] The entire system effectively achieves a load range of 0-1000N, with a measurement accuracy of ≤1% of the load.

[0052] Example 2

[0053] The difference between this embodiment and embodiment 1 is that:

[0054] See also Figure 2 , 3 4. In an embodiment of the utility model, a horizontal tensile mechanical testing machine system is provided with a testing machine elastic buffer pad at the lower end of the testing machine L-shaped transmission chain frame 20. The testing machine elastic buffer pad does not interfere with the normal operation of the horizontal tensile chain 27 and the sensor tensile connector 33. When the tensile force reaches a certain critical degree, the test piece is subjected to a large tensile force and breaks or separates. At this time, the horizontal tensile force sensor 32 obtains a maximum tensile force critical value. At this time, the sensor tensile connector 33 will rapidly approach the testing machine L-shaped transmission chain frame 20 under the action of the tensile force. When it hits the testing machine L-shaped transmission chain frame 20, a high-speed destructive force will be generated to damage the horizontal tensile force sensor 32. By adding the testing machine elastic buffer pad, it is beneficial to buffer and offset the high impact destructive force, thereby avoiding damage to the testing machine L-shaped transmission chain frame 20, the horizontal tensile force sensor 32, and the sensor tensile connector 33.

[0055] Example 3

[0056] The difference between this embodiment and embodiment 1 is that:

[0057] See also Figure 2 , 3 In the embodiment of the utility model, a horizontal tensile mechanical testing machine system is provided, in which the connection mode between the testing machine movable slide rail 26 and the testing machine sensor mounting seat 29 and the testing machine movable clamp mounting seat 34 is upgraded and improved from the original slide rail and slide groove connection mode to an electromagnetic suspension connection, and the testing machine movable slide rail 26 generates a magnetic force opposite to that of the testing machine sensor mounting seat 29 and the testing machine movable clamp mounting seat 34, so that the testing machine sensor mounting seat 29 and the testing machine movable clamp mounting seat 34 are suspended in the air, and the suspension height and horizontality are adjusted by controlling the size of the electromagnetic force, thereby reducing or eliminating the influence of various friction forces on the water quality tensile mechanical test.

[0058] In the utility model, the maximum tensile force that various assemblies can withstand is tested by applying tensile force on the horizontal plane, and the horizontal tensile mechanical performance test data is obtained, so as to evaluate the horizontal tensile mechanical performance of the assemblies. The tensile effect in the vertical to horizontal direction is realized through dual synchronous stepping lifting drive combined with a simple chain structure transmission, so as to realize the automation and intelligent control of the whole system, significantly improve the testing efficiency of the system, greatly reduce the loss of manpower and material resources, realize the available load of 0-1000N, and effectively expand the scope of use of the system. The whole system is simple and convenient to operate, and has strong usability, and has obvious practicality and application promotion value.
