Four rectangular support components are arranged below the test bench body. A connecting component is slidably connected between the two support components on the front side and between the two support components on the rear side. This greatly reduces the volume of the multifunctional mechanical metrology test bench of this utility model, making it easy to store and transport, and easy to promote to the market. As described in the above patent, when using existing mechanical metrology test benches, most devices are difficult to limit the hanging, prevent detachment, and perform tensile force detection on the test object of the corresponding size before mechanical measurement, which affects the adaptability of the device to test objects of different sizes and thus affects the testing efficiency.

[0012] Beneficial effects

[0013] This invention provides a test bench for mechanical metrology testing. Compared with the prior art, it has the following advantages:

[0014] 1. This mechanical metrology testing bench, by setting up an adjustment component within the device, allows the first handwheel to drive two sets of movable frames to move towards both sides of the object via a bidirectional screw, thus limiting the two sets of movable frames to the sides of the object and facilitating subsequent stretching operations. Two sets of second handwheels, in conjunction with two sets of first unidirectional screws, adjust the height of the two sets of movable frames, the limiting rods, the spring assembly, and the limiting plate, respectively, ensuring the limiting plate fits snugly against the top of the object. This improves the device's adaptability to objects of different sizes, enabling the detection of applied force during subsequent stretching operations and providing an anti-detachment function, thereby improving the accuracy of mechanical metrology testing.

[0015] 2. This mechanical measurement test bench, by setting a tensioning component inside the device, allows the motor and the second one-way screw to work together to adjust the height of the slide frame, tension plate, and hook. This helps the hook to hang on items of the corresponding height and perform tensioning treatment, improving the adaptability of the tensioning end to items of different sizes to be tested.

[0022] See Figures 1-4 This utility model provides the following two technical solutions:

[0023] First embodiment: A test bench for mechanical metrology testing, including a support base 1, with a test piece for mechanical metrology testing connected to the upper end of the support base 1, the test piece including:

Each limiting component 24 includes a movable frame 241 slidably connected to the two sets of sliding rods 23 and threadedly connected to the bidirectional screw 21. A vertically rotatable component is connected to the middle of the movable frame 241. A first one-way screw 242 is provided, a second handwheel 243 is installed on the top of the first one-way screw 242, a movable frame 244 is slidably connected to the movable frame 241 and threadedly connected to the first one-way screw 242, two sets of limiting rods 245 are vertically installed on both sides inside the movable frame 244, a spring assembly 246 is installed on the upper side of the movable frame 244 near the outer side of the limiting rods 245, a limiting plate 247 is installed at the bottom of the spring assembly 246 and slidably connected to the two sets of limiting rods 245, and a tensioning member 25 for pulling ropes of items is installed in the middle of the support base 1;

[0025] Two sets of storage bins 3 are placed on both sides of the bottom of the support base 1 for storing materials; two sets of sliding rods 23 are respectively set along the X-axis on the front and rear sides of the top of the support base 1; the inner ends of the movable frame 241 are respectively provided with guide rods that are slidably connected to the movable frame 244; a pressure sensor fixedly connected to the spring assembly 246 is installed on the top of the movable frame 244; the bottom of the limiting plate 247 is in contact with the movable frame 244; two sets of limiting members 24 are respectively located on both sides of the tension member 25; a support block for providing support for the materials is installed at the middle of the top of the support base 1; Wheel 22 drives two sets of movable frames 241 to move toward both sides of the item via bidirectional screw 21, so that the two sets of movable frames 241 limit the two sides of the item. Through the cooperation of two sets of second handwheels 243 and two sets of first one-way screws 242, the height of the two sets of movable frames 244, limit rods 245, spring assembly 246 and limit plate 247 are adjusted respectively, so that the limit plate 247 fits with the top of the item.

[0026] The main difference between the second implementation method and the first implementation method is that:

[0027] The tension member 25 includes a slide frame 251 that is vertically slidably connected to the support base 1. A tension plate 252 is installed on the top of the slide frame 251. An array of hooks 253 is installed on the bottom of the tension plate 252. A motor 255 is installed on the bottom of the support base 1.

[0030] In use, the user takes the item to be tested from the storage box 3, places the item on the top center of the support base 1, and rotates the first handwheel 22. The first handwheel 22 drives the two sets of moving frames 241 to move towards both sides of the item through the bidirectional screw 21. After the two sets of moving frames 241 are in contact with the sides of the item, the user stops rotating the first handwheel 22. The two sets of second handwheels 243 drive the two sets of first one-way screws 242 to rotate. The first one-way screws 242 drive the moving frame 244, the limiting rod 245, the spring assembly 246, and the limiting plate 247 to move downwards, so that the limiting plate 247... The slide frame 251, tension plate 252, and array of hooks 253 are moved to the upper side of the material by the motor 255 and the second one-way screw 254 in cooperation with the top of the material. The hooks 253 are hung on the upper end of the material. The slide frame 251, tension plate 252, and hooks 253 are moved upward by the motor 255 and the second one-way screw 254. The moving material pushes up the two sets of limiting plates 247. The limiting plates 247 compress the spring in the spring assembly 246. The spring assembly 246 transmits the force to the pressure sensor end to realize the mechanical measurement test of the material.
