Technical Field

[0001] The utility model relates to the technical field of weighing sensor detection, in particular to a detection device for a weighing sensor. Background Art

[0002] A truck weighing sensor, also known as a truck scale, is a large electronic weighing device that is used to measure the total weight of a vehicle and its cargo. It usually consists of a solid table and one or more weighing sensors that detect weight changes on the table and convert them into electrical signals. The working principle of a truck scale is based on gravity. When a vehicle enters the table, its weight is captured by the sensor and converted into electrical signals. These signals are then sent to the weighing display, which is processed to display the net weight, tare weight and gross weight of the vehicle. Truck scales are widely used in transportation companies, warehouses, ports, mines and garbage disposal to ensure transportation safety, control loading volume and meet weighing needs in commercial transactions.

[0003] At present, after the production of automobile weighing sensors is completed, it is necessary to use a detection device to detect its structural strength. However, the existing detection device has a complex structure and is inconvenient to use, which affects the detection efficiency of the automobile weighing sensor. In addition, the detection accuracy is not high and cannot meet the existing needs.

[0004] To this end, a detection device for a weighing sensor is proposed. Summary of the invention

The utility model provides a technical solution: To achieve the above-mentioned purpose, the utility model provides the following technical solution: A detection device for a weighing sensor 3, comprising: a platform 1; two support blocks 2 are symmetrically fixed on the top of the platform 1, and weighing sensors 3 are placed on the top of the two support blocks 2; a U-shaped frame 4 is fixed on the top of the platform 1, a hydraulic cylinder 5 is installed on the top of the U-shaped frame 4, and a hydraulic rod 6 penetrating the U-shaped frame 4 is installed on the bottom of the hydraulic cylinder 5; a pressing plate 7 is fixed at the bottom of the hydraulic rod 6; a mounting plate 8 is fixed between the two support blocks 2, a contact sensor 9 is installed on the top of the mounting plate 8, the top of the contact sensor 9 is 1mm away from the bottom of the weighing sensor 3, the contact sensor 9 is electrically connected to the external terminal, and a support column 10 is fixed on the top of the mounting plate 8, and the tops of the support column 10 and the contact sensor 9 are level.

[0034] Specifically, the utility model places the weighing sensor 3 on the top of the two support blocks 2, and then adjusts the stroke of the hydraulic cylinder 5 and starts the hydraulic cylinder 5. The hydraulic cylinder 5 drives the pressing plate 7 to move downward through the hydraulic rod 6, and the pressing plate 7 abuts against the weighing sensor 3 and applies pressure thereto, thereby achieving the purpose of detecting the structural strength of the weighing sensor 3. Then, the staff can use the external terminal to determine whether the contact sensor 9 is in contact with the weighing sensor 3, and then determine whether the weighing sensor 3 is deformed. According to whether the weighing sensor 3 is deformed, it can be determined whether its quality is qualified;

[0035] In summary, compared with the existing ones, the overall structure of the utility model is simple and easy to use, thereby improving the detection efficiency of the weighing sensor 3, and by judging whether the contact sensor 9 and the weighing sensor 3 are in contact, it is possible to judge whether the quality of the weighing sensor 3 is qualified, thereby improving the detection accuracy of the weighing sensor 3 and meeting the existing needs;

[0036] A support column 10 is fixed on the top of the mounting plate 8. The support column 10 and the top of the contact sensor 9 are flush with each other. If the weighing sensor 3 is of unqualified quality and is deformed during testing, the support column 10 can prevent the weighing sensor 3 from pressing on the contact sensor 9, thereby preventing the contact sensor 9 from being damaged. Example

[0037] See also Figure 1 , 2The utility model provides a technical solution: a detection device for a weighing sensor 3, wherein a limit plate 18 and a connecting plate 14 are fixed on the top of two support blocks 2, and the limit plate 18 abuts against one end of the weighing sensor 3; a threaded hole 15 is provided on the outer wall of the connecting plate 14, and a threaded rod 16 is threadedly connected to the threaded hole 15, a rotating shaft 17 is fixed to one end of the threaded rod 16, and a fixing plate 13 is rotatably connected to the other end of the threaded rod 16; the fixing plate 13 abuts against the other end of the weighing sensor 3, and a slide groove 11 is provided on the top of the two support blocks 2, and a slider 12 is installed in the slide groove 11; the support block 2 is fixed on the top of the slider 12.

[0038] Specifically, the utility model rotates the rotating shaft 17, which drives the threaded rod 16 to move in the threaded hole 15. After the fixing plate 13 at one end of the threaded rod 16 abuts against the weighing sensor 3, the weighing sensor 3 can be fixed under the action of the fixing plate 13 and the limiting plate 18, so as to avoid the weighing sensor 3 from being offset when being detected, thereby improving the detection efficiency and detection accuracy of the weighing sensor 3.

[0039] Furthermore, the distance that the threaded rod 16 moves in the threaded hole 15 can be controlled by the rotating shaft 17, so that the distance between the fixing plate 13 and the limiting plate 18 can be controlled, so that it can meet the use of weighing sensors 3 of different sizes, and the overall practicality is high.

[0040] Working principle:

[0041] First, the weighing sensor 3 is placed on the top of the two support blocks 2, and then the stroke of the hydraulic cylinder 5 is adjusted and the hydraulic cylinder 5 is started. The hydraulic cylinder 5 drives the pressing plate 7 to move downward through the hydraulic rod 6, and the pressing plate 7 abuts against the weighing sensor 3 and applies pressure to it, so as to achieve the purpose of detecting the structural strength of the weighing sensor 3. Then, the staff can use the external terminal to determine whether the contact sensor 9 is in contact with the weighing sensor 3, and then determine whether the weighing sensor 3 is deformed. According to whether the weighing sensor 3 is deformed, its quality can be determined.

[0042] In summary, compared with the existing ones, the overall structure of the utility model is simple and easy to use, thereby improving the detection efficiency of the weighing sensor 3, and by judging whether the contact sensor 9 and the weighing sensor 3 are in contact, it is possible to judge whether the quality of the weighing sensor 3 is qualified, thereby improving the detection accuracy of the weighing sensor 3 and meeting the existing needs;

[0043] Secondly, a support column 10 is fixed on the top of the mounting plate 8. The support column 10 and the top of the contact sensor 9 are level. If the weighing sensor 3 is of unqualified quality and deforms during detection, the support column 10 can prevent the weighing sensor 3 from pressing the contact sensor 9, thereby preventing the contact sensor 9 from being damaged.

[0044] Finally, by rotating the rotating shaft 17, the rotating shaft 17 will drive the threaded rod 16 to move in the threaded hole 15. After the fixing plate 13 at one end of the threaded rod 16 abuts against the weighing sensor 3, the weighing sensor 3 can be fixed under the action of the fixing plate 13 and the limiting plate 18, so as to avoid the displacement of the weighing sensor 3 during the detection, thereby improving the detection efficiency and detection accuracy of the weighing sensor 3.

[0045] Furthermore, the distance that the threaded rod 16 moves in the threaded hole 15 can be controlled by the rotating shaft 17, so that the distance between the fixing plate 13 and the limiting plate 18 can be controlled, so that it can meet the use of weighing sensors 3 of different sizes, and the overall practicality is high.
