Description

Technical Field

[0001] The utility model relates to the technical field of X-thread packaging box testing, in particular to a fixing tension testing device for an X-thread packaging box. Background Art

[0002] X threaded packaging box fixed tensile test equipment is usually used to test the tensile performance of the fixed connection parts of threaded packaging boxes when subjected to force. In this test equipment, the main test object is the connection of the threaded packaging box, which is used to evaluate its firmness and durability when subjected to tension. Therefore, it is necessary to test the coordinated tension of the tool and the base to avoid the situation where the tool is easy to fall off in the packaging box due to too small tension.

[0003] The conventional testing method of traditional tensile testing equipment requires that the outer cover of the tool box be cut open each time, so that the tool can pass through the outer cover and be inserted into the X-thread of the base, and then the tool box is fixed by bolt compression, one for clamping the threaded packaging box, and the other for fixing the bolt. There are some problems. The outer cover of the tool box must be cut open during the test of the traditional X-threaded packaging box fixing tensile testing equipment, so the test efficiency is too low and each tool box can only be scrapped after being tested once, and cannot be tested repeatedly. At the same time, the tensile test of the tool box fixed by bolt compression may cause the damage of the tool box and cannot be used again. This destructive testing method is not suitable for situations that require repeated testing because the tool box needs to be replaced for each test. Utility Model Content

Then, the external pulling tool is fixed to the mounting ring 4 at the telescopic end of the electric hydraulic push rod 3, so that the pulling tool and the drill bits and other tools are fixed. Then, the single-chip microcomputer 8 is used to control the operation of the motor 68, and the output shaft of the motor 68 drives the rotating shaft 67 to rotate, and the rotating shaft 67 drives the strip plate 66 to rotate clockwise at a certain angle, and the strip plate 66 drives the connecting rods 65 at the left and right ends to connect the strip plate 66 with the connecting rods. The pin point between the rods 65 is the center and rotates in the opposite direction to the strip plate 66, and then the pin point between the connecting rod 65 and the pressing block 63 is used as the center to rotate and drive the pressing block 63 to slide in the slide groove 64, so that the pressing block 63 can slide and avoid inside the slide groove 64, and finally the two pressing blocks 63 are moved closer to the inside until the two pressing plates 62 are in contact with the outer surface of the box body 9 and squeezed and fixed, so that more precise force application and control can be achieved, and more uniform force distribution can be brought about, avoiding the situation of local overload or uneven force application that may be caused by bolt fixing, and effectively improving the accuracy, stability and reliability of the test;

[0033] After the fixation is completed, the operation of the electric hydraulic push rod 3 is regulated by the single-chip computer 8. The telescopic end of the electric hydraulic push rod 3 applies an upward pulling force to the drill bit and other tools through the fixing device between the mounting ring 4 and the drill bit and other tools, and records the real-time tension data during the test. At the same time, the test data is recorded in time, including the applied force, deformation, etc. After the test is completed, the test data is analyzed to evaluate the tensile performance of the sample, including indicators such as tensile strength and breaking point.
