Description

Technical Field

[0001] This utility model relates to the field of quality engineering testing technology, and in particular to a quality engineering testing and measurement device. Background Technology

[0002] Metrological inspection refers to the inspection method of measuring a certain quantitative characteristic of each individual in a sample for sampling inspection. During the inspection process, the values ​​of quality characteristics are measured and recorded, and the values ​​are compared with the standard to determine whether they are qualified. Therefore, in the current quality engineering inspection process, it is often necessary to use testing and metrological equipment to ensure that the weight of the test samples is the same and that the data comparison is more standardized.

[0003] In the prior art, such as Chinese patent CN217543025U, a quality engineering testing and measurement device includes a main body of the measuring device with a display fixedly mounted on one side and a supporting mechanism fixedly set on the top of the main body. The supporting mechanism includes a tray, a magnetic block, and an inner liner movably disposed within the tray. Keyways are formed at both ends of both sides of the tray, and hollow positioning keys extending into the keyways are formed at both ends of both sides of the inner liner. Locking mechanisms can be detachably installed at both ends of both sides of the tray corresponding to the keyways. Positioning mechanisms adapted to the locking mechanisms are movably disposed within each of the multiple magnetic blocks. Internal thread seats are formed at the four corners of the bottom of the measuring device main body, and threaded holes for knob threaded connections are centrally located at the bottom of the internal thread seats. This quality engineering testing and measurement device effectively avoids contamination of the tray and prevents it from affecting subsequent use, facilitating the normal operation of testing and measurement work, and has strong applicability.

[0004] While the aforementioned patent can effectively prevent the tray from being contaminated and thus avoid affecting its subsequent use, facilitating the normal operation of testing and measurement, it is not convenient for measuring the height of fixed objects. Measurement can only be performed by finding additional tools such as rulers, which increases the operation steps and is prone to measurement errors due to the introduction of external tools, affecting the accuracy and convenience of measurement. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of the above-mentioned patent, which, although it can effectively avoid contamination of the tray and prevent it from affecting subsequent use, and facilitate the normal operation of testing and measurement work, makes it inconvenient to measure the height of objects. It can only be measured by finding additional tools such as rulers, which increases the operation steps and is prone to measurement errors due to the introduction of external tools, affecting the accuracy and convenience of measurement. Therefore, a quality engineering testing and measurement device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quality engineering testing and measurement device, comprising a base, an electronic scale fixedly connected to the top of the base, an outer tray fixedly connected to the top of the electronic scale, a fixing block fixedly connected to the top of the outer tray near the rear side, an infrared receiver fixedly connected to the top of the fixing block, a support frame fixedly connected to the top of the base near the rear side, a sliding sleeve movably connected to the outer surface of the support frame, a lead screw threaded through the top of the sliding sleeve, a measuring plate fixedly connected to the front surface of the sliding sleeve, an infrared transmitter fixedly connected to the bottom of the measuring plate, a scale groove formed on one side of the outer surface of the support frame, and an indicator fixedly connected to the front surface of the support frame near the bottom.

[0013] 1. In this utility model, by rotating the rotating ring, the measuring plate is brought into contact with the top of the solid sample. Then, under the action of the infrared emitter and infrared receiver, the height of the solid sample is calculated by the time difference or phase difference of the infrared light from emission to reception. At the same time, the position of the fixed block in the scale groove and the position of the bottom of the sliding sleeve in the scale groove can be collected.

Furthermore, fixing the fixed block and infrared receiver on the inner tray can avoid the problem of the inner tray moving downwards during measurement due to the weight of the solid sample, which would cause inaccurate measurement. It has high practicality.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-5As shown, this utility model provides a quality engineering testing and measurement device, including a base 9, an electronic scale 8 fixedly connected to the top of the base 9, an outer tray 7 fixedly connected to the top of the electronic scale 8, a fixing block 15 fixedly connected to the top of the outer tray 7 near the rear side, an infrared receiver 14 fixedly connected to the top of the fixing block 15, a support frame 3 fixedly connected to the top of the base 9 near the rear side, a sliding sleeve 2 movably connected to the outer surface of the support frame 3, a lead screw 5 threaded through the top of the sliding sleeve 2, a measuring plate 4 fixedly connected to the front surface of the sliding sleeve 2, and a fixed bottom of the measuring plate 4. An infrared transmitter 16 is connected to the support frame 3. A scale groove 1 is opened on one side of the outer surface of the support frame 3. An indicator 18 is fixedly connected to the front surface of the support frame 3 near the bottom. The position of the infrared receiver 14 is matched with the position of the infrared transmitter 16. The top of the lead screw 5 is rotatably connected to the inner top of the support frame 3. The bottom of the lead screw 5 is rotatably connected to the top of the base 9. A rotating ring 13 is fixedly connected to the outer surface of the lead screw 5 near the bottom. The indicator 18 is matched with the scale groove 1. An inner tray 6 is provided on the inner surface of the outer tray 7. Multiple counterweight rings 17 are provided at the bottom of the outer tray 7.

[0024] The overall effect of Embodiment 1 is that, when measuring fluid samples, the fluid sample can be placed inside the inner tray 6 for weight measurement. After measurement, the inner tray 6 can be removed from the outer tray 7 for cleaning to prevent contamination. When measuring solid samples, the sample is placed inside the inner tray 6, and its weight is measured using an electronic scale 8. After measurement, the rotating ring 13 can be rotated to drive the lead screw 5 to rotate along the base 9 and support frame 3, causing the sliding sleeve 2 to move downwards along the support frame 3, causing the measuring plate 4 to fit against the top of the solid sample. Then, the infrared emitter 16 can be turned on to emit infrared light, which is received by the infrared receiver 14. The infrared receiver 14 is used to calculate the height of the solid sample by measuring the time difference or phase difference between the infrared light emission and reception. The data is then transmitted to the control panel on the base 9. Simultaneously, the position of the fixing block 15 in the scale groove 1 is determined by the position of the fixing block 15 pointing to the indicator 18, and the data is collected. The bottom of the acquisition sliding sleeve 2 is located in the scale groove 1. The height of the solid sample is calculated by converting the two collected data. Using two different measurement methods allows for mutual verification of the data accuracy, improving the accuracy of the measurement. Furthermore, fixing the fixing block 15 and the infrared receiver 14 to the inner tray 6 can avoid the problem of the inner tray 6 moving downwards during measurement due to the weight of the solid sample, which would cause inaccurate measurement. This makes the method highly practical.

[0025] Example 2, as Figures 1-5As shown, the bottom of the base 9 is rotatably connected to multiple threaded sleeves 10, and the inner surfaces of the multiple threaded sleeves 10 are rotatably connected to threaded rods 11. The bottom of the multiple threaded rods 11 is fixedly connected to a placement seat 12, and the inner surface of the outer tray 7 matches the outer surface of the inner tray 6.

[0026] The effect achieved by the entire embodiment 2 is that when placing the base 9, the placement seat 12 can be pressed down, and the threaded sleeve 10 can be rotated to make the threaded sleeve 10 rotate along the threaded rod 11, thereby driving the base 9 to rise and fall. The level on the base 9 can be used to detect and adjust the levelness of the base 9, so as to adapt to different placement planes and improve the accuracy of measurement. At the same time, multiple counterweight rings 17 at the bottom of the outer tray 7 can ensure the center of gravity position of the outer tray 7.

[0027] Working principle: When measuring a solid sample, the placement seat 12 can be pressed down, and the threaded sleeve 10 can be rotated along the threaded rod 11, causing the base 9 to rise and fall. The level on the base 9 is then checked and adjusted using a level instrument. The sample is then placed inside the inner tray 6, and its weight is measured using an electronic scale 8. After measurement, the rotating ring 13 can be rotated, causing the lead screw 5 to rotate along the base 9 and support frame 3, causing the sliding sleeve 2 to move downwards along the support frame 3, bringing the measuring plate 4 into contact with the top of the solid sample. Then, the infrared emitter 16 can be turned on, emitting infrared light which is received by the infrared receiver 14. The height of the solid sample is calculated by the time difference or phase difference between the infrared light emission and reception. The data is then transmitted to the control panel of the base 9. At the same time, the position of the fixing block 15 in the scale groove 1 is determined by the position of the indicator 18, and the data is collected. The bottom of the acquisition sleeve 2 is in the scale groove 1. The height of the solid sample is calculated by converting the two collected data. Using two different measurement methods can verify the accuracy of the data and improve the accuracy of the measurement. Furthermore, fixing the fixing block 15 and the infrared receiver 14 to the inner tray 6 can avoid the problem of the inner tray 6 moving downward due to the weight of the solid sample during measurement, which would cause inaccurate measurement.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
