Description

Technical Field

[0001] The utility model relates to the technical field of scale beam fracture detection, in particular to a scale beam fracture detection device for an electronic scale. Background Art

[0002] An electronic scale is a type of weighing instrument. It is a tool that uses Hooke's law or the principle of lever balance of force to measure the mass of an object. An electronic scale mainly consists of three parts: a weighing system (such as a scale pan and a scale body), a force transmission conversion system (such as a lever force transmission system and a sensor), and an indication system (such as a dial and an electronic display instrument).

[0003] The scale bar of an electronic scale is an important structure inside the scale. In the weighing process, it is the main force-bearing mechanism, so there are high requirements for the strength of the scale bar. After the scale bar breaks, a detailed analysis of the fracture surface is required. Use a magnifying glass to check the longitudinal section of the metal surface. The method of various structural and fracture defects is called macro testing. Through macro inspection, the full picture of the metal can be seen, and the structural unevenness in terms of color, corrosion, location and direction of cracks, as well as the shape and distribution of various defects can be quickly and accurately identified. The cracks can be macro-analyzed. The approximate outline of the fracture surface can be obtained, and the cause of the damage can be understood to some extent. It can determine the crack starting position of the broken piece, the direction of crack extension, the type of fracture, the type of stress the component is subjected to, the influence of environmental media, the influence of temperature on component fracture, the degree of deformation and wear.

[0004] In order to accurately obtain the fracture surface of the scale bar, it is necessary to take photos of the fracture surface for analysis. However, the existing detection device can only take photos of a certain position of the scale bar, and it is necessary to manually change the position many times, which is troublesome to use.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figure 1-3 As shown, the electronic scale rod fracture detection device comprises a base plate 1, a gantry 2 is fixedly connected to the top of the base plate 1, an electron microscope 3 is fixedly connected to the top of the gantry 2, a fixing seat 4 is fixedly connected to the top of the base plate 1, an arc guide rail 6 is fixedly connected to the top of the fixing seat 4, a movable block 13 is slidably connected to the inside of the arc guide rail 6, a column 7 is arranged at the top of the movable block 13, a clamping assembly is installed at the top of the column 7, an arc rack 12 is fixedly connected to the front side of the arc guide rail 6, a gear 11 is meshedly connected to one side of the arc rack 12, a motor is fixedly connected to the rear end of the gear 11, and the motor is fixedly connected to the inside of the movable block 13, an electromagnetic brake is installed inside the motor at the rear end of the gear 11, the arc guide rail 6 is semicircular, and the clamping assembly is arranged at the center of the arc guide rail 6;

[0023] The broken weighing beam is fixedly clamped by the clamping assembly, with the fracture surface facing the electron microscope 3. The electron microscope 3 takes a picture of the fracture surface for analysis. When the position needs to be changed, the motor drives the gear 11 to rotate. The rotating gear 11 is subjected to the reaction force of the arc-shaped rack 12, driving the movable block 13 to move along the arc-shaped guide rail 6, thereby changing the inclination angle of the column 7. The direction of the fracture surface on the weighing beam is changed, reducing manual work and making it more convenient to use.

[0024] Specifically, Figure 1 As shown, the clamping assembly includes a bidirectional threaded rod 9, and the bidirectional threaded rod 9 is rotatably connected to the top of the column 7, and the left and right sides of the bidirectional threaded rod 9 are threadedly connected with clamps 8, and the clamps 8 are slidably connected to the top of the column 7. The width of the clamps 8 is greater than the width of the top of the column 7, so the clamps 8 can clamp the weighing beam through both sides to avoid interference between the weighing beam and the column 7. The bidirectional threaded rod 9 is rotated to make the two clamps 8 move towards each other, and the two clamps 8 act at the same time to clamp the weighing beam, which is convenient for fixing the weighing beam.

[0025] Specifically, Figure 2 and Figure 3As shown, the movable block 13 is internally rotatably connected with a connecting shaft 14, and the top end of the connecting shaft 14 is fixedly connected to the column 7, the middle part of the connecting shaft 14 is fixedly connected with a worm wheel 15, the side of the worm wheel 15 is meshingly connected with a worm 16, one end of the worm 16 is fixedly connected with a motor, and the motor is fixedly connected to the inside of the movable block 13, the motor drives the worm 16 to rotate when it works, the rotating worm 16 drives the connecting shaft 14 to rotate through the worm wheel 15, and then the column 7 is rotated at the top end of the movable block 13, thereby changing the position of the cross section of the weighing beam, and the fracture surface can be photographed and analyzed from different positions, which is more convenient to use.

[0026] Specifically, Figure 1 As shown, the left and right sides of the top of the base plate 1 are fixedly connected with fixing rods 5, and the top of the fixing rods 5 is fixedly connected to the arc guide rail 6. The arc guide rail 6 is supported by two fixing rods 5 to improve the stability of the arc guide rail 6 and prevent the arc guide rail 6 from deformation.

[0027] Specifically, Figure 1 As shown, one end of the bidirectional threaded rod 9 is fixedly connected to a handwheel 10, and an anti-skid groove is provided on the side of the handwheel 10. The handwheel 10 increases the force arm for rotating the bidirectional threaded rod 9, which is more labor-saving. The anti-skid groove is added to prevent the palm and the handwheel 10 from slipping.

[0028] Working principle: The two-way threaded rod 9 is rotated by the hand wheel 10 to make the two clamps 8 move towards each other. The two clamps 8 act at the same time to clamp the scale bar, and the fracture surface faces the electron microscope 3. The electron microscope 3 takes a picture of the fracture surface for analysis. When the position needs to be changed, the motor drives the gear 11 to rotate. The rotating gear 11 is subjected to the reaction force of the arc-shaped rack 12, driving the movable block 13 to move along the arc-shaped guide rail 6, thereby changing the inclination angle of the column 7, and the direction of the fracture surface on the scale bar changes. The motor drives the worm 16 to rotate. The rotating worm 16 drives the connecting shaft 14 to rotate through the worm gear 15, thereby causing the column 7 to rotate at the top of the movable block 13, thereby changing the position of the cross section of the scale bar. The fracture surface can be photographed and analyzed from different positions, which is more convenient to use.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
