DETAILED DESCRIPTION
[0023] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.
[0024] A molybdenum wire tensile strength detection device according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.
[0025] Example 1
[0026] For easier understanding, see Figures 1 to 4 , an embodiment of a molybdenum wire tensile strength detection device provided by the utility model comprises a fixed seat 1, a slide bar 2 is fixedly installed inside the fixed seat 1, a driving screw 3 is rotatably connected to the middle of the inner side of the fixed seat 1, a driving motor 4 is fixedly installed at one end of the fixed seat 1, a movable seat 5 is slidably connected to the outer wall of the slide bar 2, a tension sensor 6 is fixedly installed on one side of the top of the movable seat 5, a clamping assembly and a reset assembly are both provided at the detection end of the tension sensor 6 and one end of the fixed seat 1, the driving screw 3 is meshed with the bottom of the movable seat 5, and one end of the output shaft of the driving motor 4 is matched with one end of the driving screw 3;
[0027] It should be noted that the molybdenum wire is fixed by the provided clamping assembly, and then the driving screw 3 is driven to rotate by the driving motor 4. The driving screw 3 will engage with the movable seat 5 at the same time, driving the movable seat 5 to move on the slide rod 2, thereby stretching the molybdenum wire. While stretching, the tension is measured by the tension sensor 6.
[0028] The clamping assembly includes two fixed sleeves 701, several first movable grooves 702, a clamping block 703, a ball 704, an adjusting sleeve 705 and an extrusion slope 706. One end of the two fixed sleeves 701 is fixedly installed on the inner side of the detection end of the tension sensor 6 and one end of the fixed seat 1 respectively. Several first movable grooves 702 are opened at one end of the fixed sleeve 701, one end of the clamping block 703 is slidably connected to the inner side of the first movable groove 702, the ball 704 is rotatably connected to one end of the clamping block 703, the adjusting sleeve 705 is rotatably connected to the outer wall of the fixed sleeve 701, and the extrusion slope 706 is opened on the inner wall of one end of the adjusting sleeve 705. Several first movable grooves 702 are arranged in a circular array at one end of the fixed sleeve 701, one end of the adjusting sleeve 705 is sleeved on the outside of the clamping block 703, the extrusion slope 706 is against the outer wall of the ball 704, and one end of the adjusting sleeve 705 is threadedly engaged with the outer wall of the fixed sleeve 701.
[0029] It should be noted that, by providing a fixed sleeve 701, a first movable groove 702 is provided in the fixed sleeve 701, a clamp block 703 which can move up and down is installed inside the fixed sleeve 701, and then an adjustment sleeve 705 is provided, and an extrusion slope 706 is provided inside the fixed sleeve 701. By rotating the adjustment sleeve 705 to engage with the fixed sleeve 701, the extrusion slope 706 can squeeze the clamp block 703, so that the clamp block 703 is tightened, and multiple molybdenum wires are clamped from multiple angles. Moreover, as the adjustment sleeve 705 rotates, the contraction of the clamp block 703 can be changed. The tightness can freely clamp molybdenum wires of different thicknesses, thereby improving the clamping stability of the molybdenum wire, ensuring the accuracy of the molybdenum wire pulling rope strength test, and the adaptability of the pulling rope strength test for molybdenum wires of different sizes. The role of arranging the ball 704 is that when the extrusion inclined surface 706 squeezes the clamping block 703, it will produce a relative rotation of the clamping block 703 at the same time. The ball 704 can reduce the friction between the two, and as shown in the figure, the surface of the clamping block 703 used for clamping adopts a rough surface to ensure that the molybdenum wire will not slip when clamping.
[0030] Example 2
[0031] In some embodiments, Figure 4 As shown, the reset assembly includes a second movable groove 801, a support block 802 and a reset spring 803. The second movable groove 801 is opened on the inner side of the clamping block 703, the support block 802 is fixedly installed on the inner side of the first movable groove 702, the reset spring 803 is fixedly installed on the top of the support block 802, the support block 802 is located on the inner side of the second movable groove 801, and one end of the reset spring 803 is against one end of the inner wall of the second movable groove 801.
[0032] It should be noted that, by providing a reset spring 803 and a support block 802, the function of the support block 802 is to fix the reset spring 803. After the test, the adjusting sleeve 705 is rotated to retract the extrusion slope 706. At this time, the reset spring 803 is used to support the clamping block 703 so that the clamping block 703 can be automatically opened, which is convenient for next use and quick removal of the molybdenum wire.
[0033] Working principle: When in use, first insert one end of the molybdenum wire to be tested between the clamping blocks 703 on the inner side of the fixed sleeve 701, and then rotate the adjusting sleeve 705 to engage with the fixed sleeve 701, so that the extrusion bevel 706 squeezes the clamping block 703, so that the clamping block 703 is tightened, and multiple molybdenum wires are clamped from multiple angles to ensure the stability of the molybdenum wire clamping, thereby preventing the molybdenum wire from slipping or deflecting during the tensile test, thereby improving the accuracy of the molybdenum wire tensile strength test, and then drive the driving screw 3 to rotate through the driving motor 4, and the driving screw 3 will also engage with the movable seat 5, driving the movable seat 5 to move on the slide bar 2, so as to stretch the molybdenum wire, and measure the tension through the tension sensor 6 at the same time. After the test is completed, rotate the adjusting sleeve 705 to retract the extrusion bevel 706. At this time, the reset spring 803 is used to support the clamping block 703, so that the clamping block 703 can automatically open and remove the tested molybdenum wire.
