Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of impellers, in particular to a hardness detection device for a high-strength fiber-reinforced impeller. Background Art
[0002] The impeller is an important mechanical component, primarily used for energy conversion and fluid transmission. The impeller works by rotating blades to achieve energy conversion. When the impeller is in operation, liquid, gas, or other fluids interact with the blades, transferring the fluid's kinetic energy to the blades, causing the impeller to rotate. Because the impeller is frequently used, its strength determines its service life. To increase its strength, high-strength fiber is generally used to reinforce it. After the impeller is reinforced, its hardness needs to be tested to determine the pressure it can withstand.
[0003] A detection device is used when testing the hardness of an impeller. However, there are still some problems with the traditional detection device when it is used. When the traditional detection device is used to test the impeller, since the bottom end of the impeller is round, it is easy to cause unstable clamping when clamping it, causing the position to move during testing, affecting the test data. Therefore, a high-strength fiber-reinforced impeller hardness detection device is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] The present invention provides a device for detecting the hardness of a high-strength fiber-reinforced impeller. Figure 1-Figure 7 As shown, a hardness detection device for a high-strength fiber-reinforced impeller includes a workbench 1 and a support frame 2; a support frame 2 is provided at the top of the workbench 1, a cylinder 3 is provided at the top of the support frame 2, a detection head 4 is provided at the bottom end of the cylinder 3, and a pressure detection module 6 is provided inside the detection head 4; a placement seat 5 is provided at the top of the workbench 1, fixed plates 8 are provided on both sides of the placement seat 5, a clamping structure 9 is provided inside the fixed plate 8, and an adjustment structure 7 is provided on one side of the fixed plate 8.
[0025] In a further preferred embodiment of the present invention, Figure 1-Figure 7As shown in the figure: the adjustment structure 7 includes a fixed block 701, a rotary cover 702, a guide seat 703, a screw sleeve 704, a screw 705 and a guide block 706. The fixed block 701 is arranged at the front end of the fixed plate 8 at the top of the workbench 1, and the guide seat 703 is arranged at the rear end of the fixed plate 8 at the top of the workbench 1. The interior of the fixed block 701 is provided with a screw rod 705, and the outer side of the screw rod 705 is provided with a screw sleeve 704. One end of the screw sleeve 704 is connected to one end of the fixed plate 8, and the interior of the guide seat 703 is provided with a guide block 706. One end of the guide block 706 is connected to the other end of the fixed plate 8. The top of the screw rod 705 is provided with a rotary cover 702, and the guide block 706 is inserted into the interior of the guide seat 703. A sliding connection is formed between the guide block 706 and the guide seat 703. The outer side of the screw rod 705 is provided with an external thread, and the inner side of the screw sleeve 704 is provided with an internal thread. A threaded connection is formed between the screw 705 and the screw sleeve 704.
[0026] Specifically, when testing the hardness of the impeller, its bottom end is inserted into the interior of the placement seat 5. After the insertion is completed, the position of the clamping plate 903 is adjusted according to the length of the bottom end. The rotary cover 702 is rotated during adjustment. As the rotary cover 702 rotates, the screw 705 is driven to rotate. The rotating screw 705 will move the screw sleeve 704 to a position. When the screw sleeve 704 moves, it will drive the fixed plate 8 to move as well, thereby indirectly driving the clamping plate 903 to move a position. When the clamping plate 903 is adjusted to a suitable clamping position, it stops moving, thereby completing the height adjustment of the clamping plate 903.
[0027] In a further preferred embodiment of the present invention, Figure 1-Figure 7 As shown: the clamping structure 9 includes a rotating rod 901, a guide rod 902, a clamping plate 903, an adjustment groove 904 and a rotating groove 905. The rotating groove 905 is opened inside the fixed plate 8, and a rotating rod 901 is arranged inside the rotating groove 905. One end of the rotating rod 901 is movably connected to the clamping plate 903. Guide rods 902 are provided at both ends of one side of the clamping plate 903. One end of the guide rod 902 passes through the interior of the fixed plate 8. The adjustment groove 904 is opened at the middle position on both sides of the placement seat 5. The rotating rod 901 is inserted into the interior of the rotating groove 905. A threaded connection is formed between the rotating rod 901 and the rotating groove 905. Two groups of guide rods 902 are provided, and the two groups of guide rods 902 are symmetrically distributed on one side of the clamping plate 903.
[0028] Specifically, after the height adjustment of the clamping plate 903 is completed, the rotating rod 901 is rotated. As the rotating rod 901 and the rotating groove 905 rotate, the clamping plate 903 is pushed to one side so that it rests against the bottom end of the impeller. By using two sets of clamping plates 903, the impeller is clamped so that it will not move around during testing. After the clamping is completed, the cylinder 3 is started to push the detection head 4 downward to perform a strength squeeze on the impeller. In the process of squeezing, the pressure detection module 6 is used to synchronously transmit data to the terminal, thereby completing the strength test of the impeller.
[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
