Description

Technical Field

[0001] The invention relates to the technical field of precision weighing, in particular to an automatic precision experimental weight tester. Background Art

[0002] Automated precision testing is a method of using automation technology to conduct high-precision tests, which can reduce errors caused by manual operations and improve the accuracy and repeatability of tests. During field resource exploration, some laboratories are mostly temporary and their internal environment is relatively poor. In order to obtain test targets and collect test data as quickly as possible, quantitative sample weighing tests are usually carried out on-site in temporary laboratories.

[0003] At present, the existing equipment using weights for mass measurement usually encounters the following problems when using weights:

[0004] 1. Manually loading weights is not only inefficient, but also prone to weight drops, causing the weights to collide and be damaged, resulting in deviations in their own values, affecting the measurement accuracy during subsequent use;

[0005] Second, the outdoor environment is relatively harsh. After being used many times, some dirt will adhere to the surface of the weights. The weight of the dirt itself will increase the deviation of the final measurement data collection during the automated precision test, thereby reducing the accuracy of the test results. Manual loading of weights cannot clean the surface of the weights in time, resulting in the inability to ensure the consistency of the weight of each loaded weight during the multiple weight addition process, which makes the test results non-repeatable, increases the randomness of the test results, and causes the test results to be inaccurate. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides an automated precision test weight tester, which adopts a mechanical method of adding weights instead of manually adding weights, and at the same time uses a brush to clean the outer surface of the weight before loading it to ensure the accuracy of the weight's own value.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Embodiment 1:

[0039] See also Figure 1-8 An automated precision test weight tester comprises a support platform 1, wherein the lower end surface of the support platform 1 is provided with feet 11 arranged in a matrix, the lower end of the support platform 1 is provided with threaded holes arranged in a matrix, the upper end of the feet 11 is provided with a threaded section and is screwed into the threaded hole, a weighing balance 2 is fixedly provided at the upper left end of the support platform 1, an L-shaped plate 3 is fixedly connected to the upper end of the support platform 1, a strip through groove is provided at the lower middle part of the left side of the L-shaped plate 3, the right side of the weighing balance 2 passes through the strip through groove and is located on the inner side of the L-shaped plate 3, and a weight storage assembly 4 is fixedly provided at the upper right end of the support platform 1.

[0040] The weight storage assembly 4 includes a rotating unit 41, a cleaning sleeve 42, flexible bristles 43, a support spring 44 and a support plate 45. The rotating unit 41 is fixedly arranged on the upper end of the right side of the support platform 1, and the cleaning sleeve 42 is fixedly connected to the upper end of the rotating unit 41. Flexible bristles 43 are evenly arranged on the inner wall of the cleaning sleeve 42. A support spring 44 is fixedly installed on the bottom of the cleaning sleeve 42, and a support plate 45 is fixedly connected to the upper end of the support spring 44. The edge of the support plate 45 is in contact with the flexible bristles 43, and a double-sided adhesive layer is arranged on the side wall of the edge of the support plate 45.

[0041] The rotating unit 41 includes a servo motor 411, a first gear 412, a second gear 413 and a rotating shaft 414. The servo motor 411 is fixedly installed on the upper right end of the support platform 1 through a motor base. The first gear 412 is fixedly installed on the upper end of the servo motor 411.

The second gear 413 is fixedly installed on the rotating shaft 414, and the lower end of the rotating shaft 414 is rotatably installed on the upper end of the support platform 1.

[0042] During specific work, before weighing, the weight is manually placed in the cleaning sleeve 42. Under the action of the weight's own gravity, the support spring 44 will be compressed, and the support plate 45 will move downward. After the weight loading assembly 5 clamps the weight, the servo motor 411 is started, and the first gear 412 is driven to rotate by the servo motor 411.

At this time, the reaction force of the support spring 44 will drive the support plate 45 to move upward and shake off the dirt inside the flexible bristles 43. Since a double-sided adhesive layer is provided on the edge side wall of the support plate 45, the double-sided adhesive layer can absorb this part of the dirt, thereby ensuring the cleanliness of the flexible bristles 43, thereby improving its cleaning effect.

The lower end of the rectangular block 515 is rotatably mounted with the vertical shaft 521, and the third gear 522 is fixedly mounted on the vertical shaft 521. A rectangular rack 523 is fixedly arranged at the lower end of the rear side of the circular ring plate 511. The rectangular rack 523 is meshed with the third gear 522. The lower end of the rectangular block 515 A connecting frame 525 is symmetrically installed, and a mounting plate 524 is fixedly connected to the lower end of the connecting frame 525. A rotating plate 526 is rotatably arranged in the middle of the mounting plate 524. The rotating plate 526 is fixedly connected to the lower end of the vertical shaft 521. An annular airbag 527 is fixedly arranged near the edge of the lower end of the mounting plate 524. A compression spring 528 is arranged inside the annular airbag 527. A plurality of air guide tubes 529 are installed along the circumference of the outer side wall upper end of the annular airbag 527. The lower end of the air guide tube 529 extends to the bottom of the mounting plate 524 and is installed with an air nozzle 5210.

[0048] The weight clamping unit 53 includes an electric push rod 531, a push plate 532, a through hole 533, a clamping bag ring 534, an electromagnet block 535, an expansion air bag 536, a reset spring 537, a magnet block 538 and a conveying pipe 539. The lower end of the rotating disk 526 is fixedly installed with an electric push rod 531 through a push rod base. The lower end of the electric push rod 531 is fixedly connected to the push plate 532. The push plate 532 is evenly provided with through holes 533. The diameter of the through holes 533 is gradually increased from top to bottom. Gradually decreasing, a clamping bag ring 534 is fixedly provided on the inner wall of the through hole 533, an electromagnet block 535 is fixedly provided at the lower end of the pushing plate 532, an expansion airbag 536 is fixedly installed at the lower end of the electromagnet block 535, a return spring 537 is provided inside the expansion airbag 536, a magnet block 538 is fixedly installed at the lower end of the expansion airbag 536, a plurality of conveying pipes 539 are evenly provided along the circumference of the upper end of the outer side wall of the expansion airbag 536, and the upper end of the conveying pipe 539 is connected with the inside of the clamping bag ring 534.

[0049] One point that needs to be explained is that, in this embodiment, the lower end of the annular airbag 527 and the upper end surface of the push plate 532 are slidably matched.

[0050] During the specific operation, when weighing, the test personnel firstly adjust the weighing balance 2 to zero, and then start the electric push rod 531, which drives the push plate 532 to move downward, so that the clamping bag ring 534 moves to the neck of the weight, and the electromagnet block 535 is energized. After the electromagnet block 535 is energized, it will generate a magnetic force that attracts the magnet block 538 and absorb the magnet block 538, and the reset spring 537 will be compressed, and the gas inside the expansion airbag 536 will enter the clamping bag ring 534 through the delivery pipe 539, so that the clamping bag ring 534 expands, so as to achieve the purpose of clamping and fixing the weight, and then the electric push rod 531 is reset and drives the push plate 532 and the clamped weight to move upward;

[0051] During the upward movement of the push plate 532, the push plate 532 will continuously squeeze the annular airbag 527. At this time, the air inside the annular airbag 527 will be transported to the air nozzle 5210 through the air guide tube 529, and then sprayed to the surface of the weight through the air nozzle 5210, so as to further improve the cleaning effect. At the same time, the driving motor 512 is started, and the threaded rod 514 is driven to rotate by the driving motor 512. Under the action of the limiting slide bar 516, the rectangular block 515 will move to the left. At the same time, under the meshing action of the rectangular rack 523 and the third gear 522, the vertical shaft 521 can rotate and drive the rotating plate 526, the electric push rod 531, the push plate 532 and the clamped weight to rotate. In this way, the air sprayed by the air nozzle 5210 can evenly and completely blow and clean the outer wall of the weight.

[0052] When the rectangular block 515 drives the limit slide bar 516 to move to the left, the cross bar 54 will also move to the left synchronously. At this time, the gravity of the T-shaped gravity rod 57 will drive the traction rope 58 to move downward. At the same time, the T-shaped gravity rod 57 itself will move downward and drive the limit ring plate 59 to move downward. When the push plate 532 moves to the same axis as the limit ring plate 59, the electric push rod 531 will drive the push plate 532 and the clamped weight to move downward. At this time, the electromagnet block 535 is powered off, and the reset spring 537 is reset. The reaction force will drive the expansion airbag 536 to expand, and the clamping bag ring 534 will shrink and contact to clamp and fix the weight. At this time, the weight will be placed in the weight pan on the right side of the weighing balance 2. At this time, the weighing balance 2 will be in a state of high on the left and low on the right. The experimenter will place the specimen resources in the loading pan on the left side of the weighing balance 2 until the weighing balance 2 is in a balanced state. During this process, the limiting ring plate 59 can play a certain limiting role on the weight in the weight pan, thereby preventing it from falling and being damaged.

[0053] The working principle of the present invention when in use:

[0054] 1. Before weighing, the weight is manually placed in the cleaning sleeve 42. Under the weight of the weight, the support spring 44 will be compressed, and the support plate 45 will move downward. Then, the electric push rod 531 is started, and the push plate 532 is driven downward by the electric push rod 531, so that the clamping bag ring 534 moves to the neck of the weight. The electromagnet block 535 is energized. After the electromagnet block 535 is energized, it will generate a magnetic force that attracts the magnet block 538 and attracts the magnet block 538. The reset spring 537 will be compressed, and the gas in the expansion airbag 536 will enter the clamping bag ring 534 through the delivery pipe 539, so that the clamping bag ring 534 expands, thereby achieving the purpose of clamping and fixing the weight.

[0055] 2. After the above step 1 is completed, the servo motor 411 is started, and the first gear 412 is driven to rotate by the servo motor 411. Under the action of the second gear 413, the rotating shaft 414 will also rotate and drive the cleaning sleeve 42 to rotate synchronously, and the flexible bristles 43 inside the cleaning sleeve 42 can evenly sweep the surface of the weight, thereby sweeping off the dirt on its surface, and then the weight loading assembly 5 will drive the weight to move upward. At this time, the reaction force of the support spring 44 will drive the support plate 45 to move upward and shake off the dirt inside the flexible bristles 43. Since a double-sided adhesive layer is provided on the edge side wall of the support plate 45, the double-sided adhesive layer can absorb this part of the dirt, thereby ensuring the cleanliness of the flexible bristles 43, thereby improving its cleaning effect;

[0056] 3: Then the electric push rod 531 is reset and drives the push plate 532 and the clamped weight to move upward. During the upward movement of the push plate 532, the push plate 532 will continuously squeeze the annular airbag 527. At this time, the air inside the annular airbag 527 will be transported to the air nozzle 5210 through the air guide tube 529, and then sprayed to the surface of the weight through the air nozzle 5210, further improving the cleaning effect. At the same time, the drive motor 512 is started, and the threaded rod 514 is driven to rotate by the drive motor 512. Under the action of the limiting slide bar 516, the rectangular block 515 will move to the left. At the same time, under the meshing action of the rectangular rack 523 and the third gear 522, the vertical shaft 521 can rotate and drive the rotating plate 526, the electric push rod 531, the push plate 532 and the clamped weight to rotate. In this way, the air sprayed by the air nozzle 5210 can evenly and completely blow and clean the outer wall of the weight.

[0057] Fourth: When the rectangular block 515 drives the limit slide bar 516 to move to the left, the cross bar 54 will also move to the left synchronously. At this time, the gravity of the T-shaped gravity rod 57 will drive the traction rope 58 to move downward. At the same time, the T-shaped gravity rod 57 itself will move downward and drive the limit ring plate 59 to move downward. When the push plate 532 moves to the same axis as the limit ring plate 59, the electric push rod 531 will drive the push plate 532 and the clamped weight to move downward. At this time, the electromagnet block 535 is powered off, and the reset spring 537 The reaction force will drive the expansion airbag 536 to expand, and the clamping bag ring 534 will shrink and contact the clamping and fixing effect on the weight. At this time, the weight will be placed in the weight plate on the right side of the weighing balance 2. At this time, the weighing balance 2 will be in a state of high on the left and low on the right. The test personnel will place the specimen resources in the loading plate on the left side of the weighing balance 2 until the weighing balance 2 is in a balanced state. In this process, the limiting ring plate 59 can play a certain limiting role on the weight in the weight plate, thereby preventing it from falling and being damaged;

[0058] Five: After the weighing test is completed, the weight is clamped and placed in the cleaning sleeve 42 through the above operation.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
