Abstract
Description
Technical Field
[0001] This invention relates to the field of weighing characteristic testing, and in particular to a weighing characteristic testing device with tilt testing function. Background Technology
[0002] While traditional weighing equipment can achieve relatively accurate weight measurements, in practical use, factors such as unevenness of the placement platform or shaking during transportation can lead to deviations in the weighing results. To ensure measurement accuracy, the industry commonly uses calibration methods under static conditions to reduce the influence of these external factors. However, this method cannot fully simulate the real working environment, especially in situations where weighing stability under dynamic conditions needs to be considered.
[0003] Currently, there are two main approaches to addressing the stability issues of weighing equipment. The first is to indirectly improve the overall system's anti-interference capability by increasing the sensitivity and accuracy of the weighing sensor itself. This method has the advantage of significantly improving measurement accuracy under static conditions, but it is costly and has limited resistance to external physical disturbances. The second method involves installing vibration damping devices or balancing mechanisms on the weighing platform to absorb or counteract the impact of external vibrations on the measured values. While this approach can alleviate measurement errors under dynamic conditions to some extent, it does not effectively handle the problem of center of gravity shift caused by changes in tilt angle, and therefore requires further improvement. Summary of the Invention
[0004] To improve the problem of poor stability test results of weighing devices in related technologies, the present invention provides a weighing characteristic testing device with tilt test function.
[0005] The weighing characteristic testing device with tilt testing function provided by the present invention adopts the following technical solution: A weighing characteristic testing device with tilt testing function includes a test bracket, an adjustable base at the bottom of the test bracket, a support plate on the test bracket, the support plate being located above the adjustable base, an adjusting cylinder on the top wall of the adjusting base, one end of the adjusting cylinder near the support plate being rotatably connected to the bottom wall of the support plate, a tilting shaft on the adjusting base, the adjusting base being hinged to the support plate via the tilting shaft, a pair of adjusting cylinders being provided, the line connecting the pair of adjusting cylinders and the tilting shaft being perpendicular, a string of weights on the test bracket, the weights being located above the support plate, and a driving device on the test bracket for moving the string of weights.
[0006] By adopting the above technical solution, when the weighing characteristic testing device with tilt testing function of the present invention is used, the operator places the scale on the support plate. Then, the operator controls the adjusting cylinder to move the support plate. Through the cooperation of the adjusting cylinder and the support plate, the support plate tilts 1-6 degrees under the action of the tilting shaft. Then, the weight string is placed on the scale for weighing. By comparing the scale reading and the weight string reading, it is determined whether the scale will produce errors when weighing in the tilted state, and the range of errors. In addition, by simulating the environment of the scale in actual use, the accuracy of the scale is tested. By adjusting the scale with poor accuracy, the accuracy of the scale during weighing is increased.
[0007] Optionally, the bottom wall of the support plate is provided with clamping rods, and there are two pairs of clamping rods. Each pair of clamping rods is positioned above an adjusting cylinder. Each pair of clamping rods is arranged in parallel. A sliding groove is formed on the side wall opposite to each pair of clamping rods. A sliding rod is inserted into the sliding groove and is slidably connected to the sliding groove. A sliding ring is provided at the output end of the adjusting cylinder, and the sliding ring is rotatably connected to the output end of the adjusting cylinder.
[0008] By adopting the above technical solution, when the output end of the adjusting cylinder moves up and down, the adjusting cylinder drives the sliding rod to move in the sliding groove. As the sliding rod moves, the bearing plate tilts, causing the scale placed on the bearing plate to shift, thereby adjusting the shift angle of the scale and increasing the stability of the bearing plate when bearing the scale.
[0009] Optionally, the test bracket is provided with a limiting plate, which is located on the side of the bearing plate away from the tilting axis. A clearance groove is provided through the side wall of the limiting plate, through which the weight string passes. The diameter of the clearance groove is larger than the maximum diameter of the weight string.
[0010] By adopting the above technical solution, the structure of the relief groove makes it less likely for the weight string to swing when it passes through the relief groove and is placed on the support plate of the scale, thereby increasing the stability of the measurement when the scale is deviated.
[0011] Optionally, the driving device includes a drive motor and a drive screw. The drive motor is mounted on the test bracket, and the drive screw is located at the output end of the drive motor. The test bracket has a drive hole, through which the drive screw passes. The drive screw is connected in series with weights.
[0012] By adopting the above technical solution, the operator can control the weight string to move towards the support plate through the drive motor and drive screw, so that when the scale is placed on the support plate, the weight string can fall into the scale in the vertical direction, and thus the scale in the offset state can weigh the weight string.
[0013] Optionally, the weight string includes measuring weights, an upper connecting part, and a connecting part. The upper connecting part includes a connecting rod and a locking disc. The connecting rod is connected to the end wall of the drive screw. The end of the connecting rod away from the drive screw is connected to the upper connecting part. The measuring weights are disposed at the end of the drive screw away from the drive motor. Several measuring weights are disposed. A locking groove is formed on the top wall of the measuring weights near the drive screw. The locking disc is inserted into the locking groove and is fixedly connected to the locking groove.
[0014] By adopting the above technical solution, when the drive motor drives the drive screw to move towards the support plate, the drive screw drives the weight string to move down. When the bottom of the weight string is connected to the support plate, the drive motor can control the number of weights falling onto the support plate, thereby obtaining multiple sets of readings from the scale. By using multiple sets of measurement data, the weighing accuracy of the scale can be tested, thus improving the accuracy of the test results.
[0015] Optionally, a first connecting groove is formed on the bottom wall of the measuring weight, a connecting block is provided in the first connecting groove, a second connecting groove is formed on the bottom wall of the first connecting groove, the first connecting groove and the second connecting groove are connected, a connecting pin is provided in the second connecting groove, the connecting block is clearance-fitted with the first connecting groove, and a connecting pin of the measuring weight is integrally formed with the connecting block in the measuring weight below the measuring weight.
[0016] By adopting the above technical solution, the structure of the first connecting groove, the second connecting groove and the connecting block allows several weights to be dropped onto the scale in sequence when the driving screw moves the weight string downward, thereby facilitating the acquisition of multiple sets of readings and improving the accuracy of the test results.
[0017] Optionally, a connecting rope is provided on the side wall of the test bracket, and a number of sensitive weights are threaded through the connecting rope, arranged vertically.
[0018] By adopting the above technical solution, the structure of the sensitive weight allows workers to measure the flicker point of the scale by placing the sensitive weight on it, further increasing the accuracy of the test results.
[0019] Optionally, the support plate is detachably connected to the tilting shaft, and the support plate is detachably connected to the adjusting cylinder.
[0020] By adopting the above technical solution, the detachable connection between the bearing plate, the adjusting cylinder, and the tilting shaft allows the staff to replace the bearing plate more conveniently, reducing the possibility of inaccurate measurement results due to the bearing plate being used for too long.
[0021] Optionally, the test bracket is provided with a recording device, which is positioned toward the support plate.
[0022] By adopting the above technical solution, the recording device can read and record the scale reading on the support plate in real time, which facilitates the analysis and testing of the scale reading.
[0023] In summary, the present invention has at least one of the following beneficial effects: 1. In the weighing characteristic testing device with tilt testing function of the present invention, when in use, the operator places the scale on the support plate. Then, the operator controls the adjusting cylinder, which moves the support plate. Through the cooperation of the adjusting cylinder and the support plate, the support plate tilts 1-6 degrees under the action of the tilting shaft. Then, a string of weights is placed on the scale for weighing. By comparing the scale reading and the reading of the weight string, it is determined whether the scale will produce errors when weighing in the tilted state, and the range of errors. In addition, by simulating the environment of the scale in actual use, the accuracy of the scale is tested. By adjusting the scale with poor accuracy, the accuracy of the scale during weighing is increased.
[0024] 2. The drive motor drives the drive screw to move towards the support plate. The drive screw drives the weight string to move down. When the bottom of the weight string is connected to the support plate, the drive motor can control the number of weights falling onto the support plate, thereby obtaining multiple sets of readings from the scale. By using multiple sets of measurement data, the weighing accuracy of the scale can be tested, thus improving the accuracy of the test results. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.
[0027] This invention discloses a weighing characteristic testing device with tilt testing function. (Refer to...) Figure 1 and Figure 2 The weighing characteristic testing device with tilt testing function includes an adjusting base 11, which is placed vertically. A test bracket 1 is bolted to the top wall of the adjusting base 11, and an adjusting cylinder 13 is bolted to the top wall of the adjusting base 11. A support plate 12 is detachably connected to the test bracket 1 by bolts. The support plate 12 is used to place the scale and is located above the adjusting cylinder 13. A tilting shaft 14 is bolted to the adjusting base 11 and is detachably connected to the center of the bottom wall of the support plate 12 by bolts. As the tilting shaft 14 rotates, the support plate 12 can tilt. The output end of the adjusting cylinder 13 is rotatably connected to the bottom wall of the support plate 12, and as the output end of the adjusting cylinder 13 moves, the support plate 12 is driven to tilt.
[0028] A connecting rope is glued to the side wall of the test bracket 1, and a sensitive weight is threaded through the connecting rope. Operators can measure the flicker point of the scale by placing the sensitive weight on it, further increasing the accuracy of the test results. A recording device 7, which is a camera, is fixedly installed on the test bracket 1. The recording device 7 is used to read the readings of the scale placed on the support plate 12.
[0029] Reference Figure 2 and Figure 3A pair of adjusting cylinders 13 are provided, and the pair of adjusting cylinders 13 are respectively located on adjacent sides of the adjusting base 11. The line connecting the pair of adjusting cylinders 13 and the inclined rotating shaft 14 is perpendicular to each other. Clamping rods 2 are welded and fixed to the bottom wall of the bearing plate 12. Two pairs of clamping rods 2 are provided, with each pair of clamping rods 2 corresponding to one adjusting cylinder 13. Each pair of clamping rods 2 is arranged in parallel, and a sliding groove 21 is formed on the side wall of each pair of clamping rods 2 near the adjusting cylinder 13. A sliding rod 22 is inserted into the sliding groove 21, and the sliding rod 22 slides along the length of the sliding groove 21. A sliding ring 23 is fixedly connected to the end wall of the adjusting cylinder 13 near the clamping rod 2. The sliding rod 22 is inserted into the sliding groove 21, the side wall of the sliding groove 21 is inclined, and the end wall of the sliding rod 22 is fitted against the inner side wall of the sliding groove 21. When the output end of the adjusting cylinder 13 moves up and down, the adjusting cylinder 13 drives the sliding rod 22 to move within the sliding groove 21. As the sliding rod 22 moves, the bearing plate 12 tilts, causing the scale placed on the bearing plate 12 to shift, thereby adjusting the shift angle of the scale and increasing the stability of the bearing plate 12 when bearing the scale.
[0030] Reference Figure 2 A limiting plate 3 is provided on the top wall of the support plate 12, and a clearance groove 31 is provided through the center of the limiting plate 3. A weight string 15 is provided on the top of the test bracket 1, and the weight string 15 passes through the clearance groove 31. A driving device is provided on the top of the weight string 15, and the driving device is used to control the movement of the weight string 15. The driving device includes a drive motor 4 and a drive screw 41. The drive motor 4 is fixedly connected to the top of the test bracket 1 by bolts. A drive hole 42 is provided vertically through the top wall of the test bracket 1, and the drive screw 41 passes through the drive hole 42. The drive screw 41 is located on the bottom wall of the drive motor 4, and the weight string 15 is connected to the drive screw 41. When the drive motor 4 drives the drive screw 41 to move downward, the weight string 15 moves to the scale located on the support plate 12, and, in conjunction with the adjusting cylinder 13, offsets the support plate 12 and the scale, thereby realizing the detection of the weighing status of the scale under different offset conditions.
[0031] Reference Figure 2 and Figure 4The weight string 15 is composed of several weighing weights. Each weighing weight has a first connecting groove 61 on its bottom wall and a second connecting groove 62 on its inner side wall. The first connecting groove 61 and the second connecting groove 62 are connected. A connecting block 6 is inserted into the first connecting groove 61 and a connecting pin 63 is inserted into the second connecting groove 62. The connecting pin 63 and the second connecting groove 62 are fitted with a clearance. The connecting pin 63 on a weight string 15 is integrally formed with the connecting block 6 in the weighing weight below it. A locking groove 53 is provided on the top wall of the weighing weight closest to the driving device. A locking plate 52 is fixedly inserted into the locking groove 53. A connecting rod 51 is fixedly connected to the end wall of the driving screw 41 near the locking plate 52 by bolts. The locking plate 52 of the connecting rod 51 is connected to the bottom end of the driving screw 41.
[0032] The implementation principle of a weighing characteristic testing device with tilt testing function according to an embodiment of the present invention is as follows: When the weighing characteristic testing device with tilt testing function of the present invention is used, the operator places the scale on the support plate 12 and adjusts the tilt of the support plate 12 by adjusting the cylinder 13. As the output end of the adjusting cylinder 13 extends, the drive motor 4 is controlled to drive the drive screw 41 and the weight string 15 to move down, so that the weight string 15 falls onto the support plate 12 in sequence. The scale reading is read by the recording device 7. By comparing the scale reading and the reading of the weight string 15, it is determined whether the scale will produce an error when weighing in a tilted state, and the range of the error. Then, by simulating the environment of the scale in actual use, the accuracy of the scale is tested, and the scale with poor accuracy is adjusted to increase the accuracy of the scale when weighing.
[0033] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
