Description

Technical Field

[0001] This utility model relates to the field of inspection tool technology, specifically a nine-parameter inspection tool. Background Technology

[0002] The nine-section pneumatic external measurement parameter gauge is a high-precision pneumatic measurement technology, mainly used for the outer diameter measurement of complex cross-sections (such as porous or irregularly shaped structures). Its core principle is to simultaneously collect dimensional data at different positions of the cross-section using multiple sets of pneumatic probes, and combine this with the float or digital display system of the pneumatic gauge to achieve rapid calibration and error analysis.

[0003] Existing external pneumatic calibration gauges typically require individual, sequential measurements of each parameter, or the use of multiple independent gauges, resulting in low testing efficiency. Furthermore, they cannot ensure a unified and stable positioning benchmark for all measurements, leading to accumulated errors due to multiple clamping or benchmark conversions. Additionally, existing external pneumatic calibration gauges usually require each pneumatic probe to be independently connected to the air source or measuring instrument, resulting in messy piping behind the equipment, easy connection errors, and space consumption. Therefore, there is an urgent need for a nine-parameter gauge to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a nine-parameter gauge to solve the problems mentioned in the background art regarding existing external pneumatic calibration parameter gauges. In use, each parameter usually needs to be measured individually and sequentially, or multiple independent gauges are required, resulting in low detection efficiency and the inability to ensure that all measurements have a unified and stable positioning reference, which leads to accumulated errors due to multiple clamping or reference conversion. Furthermore, in existing external pneumatic calibration parameter gauges, each pneumatic probe usually needs to be independently connected to the air source or measuring instrument, resulting in messy pipelines behind the equipment, easy connection errors, and space occupation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A nine-parameter gauge includes a base, an integrated positioning block on the top of the base, multiple calibration gauge heads on both the front and rear sides of the integrated positioning block, a protective block on the top of each calibration gauge head, a standard component between the front and rear calibration gauge heads, a venting interface on each calibration gauge head, and a compressed gas interface terminal on the bottom of the base.

[0006] As a preferred technical solution of this utility model, the two calibration gauge probes arranged one in front of the other constitute a measurement group, and the measurement group is set to nine groups.

[0007] As a preferred embodiment of this utility model, one end of the compressed gas interface terminal has nine interfaces connected to nine gas and electricity meters.

[0008] As a preferred embodiment of this utility model, the standard component is located directly above the integrated positioning block.

[0009] As a preferred technical solution of this utility model, the base has four openings, and the four openings are arranged in pairs opposite each other about the base.

[0010] As a preferred technical solution of this utility model, the calibration gauge heads on the front and rear sides are arranged symmetrically about the standard part.

[0011] As a preferred embodiment of this utility model, the nine measurement groups are arranged side by side.

[0012] As a preferred embodiment of this utility model, all of the multiple ventilation ports are connected to one end of the compressed gas interface terminal via connecting pipes.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model integrates all gas circuits onto a single terminal, enabling one-wire connection, which makes the connection with external gas and electricity meters very simple, standardized, and easy to install and maintain.

[0014] 2. This utility model, through nine sets of measurement groups arranged side by side, allows for the simultaneous detection of nine parameters after the workpiece is placed in one go, which greatly improves the detection efficiency. Secondly, the integrated positioning block ensures that all measurements have a unified and stable positioning reference, avoiding the cumulative error caused by multiple clamping or reference conversion. At the same time, the position of all probes relative to the positioning block is fixed, ensuring the consistency of measurement conditions each time, and the measurement results are more reliable.

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0018] Please see Figure 1-3 A nine-parameter gauge includes a base 1, with an integrated positioning block 2 on the top of the base 1. The integrated positioning block 2 ensures that all measurements have a unified and stable positioning reference, avoiding cumulative errors caused by multiple clamping or reference conversion. At the same time, the position of all probes relative to the positioning block is fixed, ensuring the consistency of measurement conditions each time and making the measurement results more reliable. Multiple calibration gauge probes 3 are set on the front and rear sides of the integrated positioning block 2. Protective blocks 4 are set on the top of the multiple calibration gauge probes 3. Standard parts 5 are set between the front and rear calibration gauge probes 3. Air inlets 6 are set on the multiple calibration gauge probes 3. Compressed gas interface terminals 7 are set on the bottom of the base 1, integrating all gas paths into one terminal, realizing one-line access, making the connection with external gas and electrical meters very simple and standardized, and easy to install and maintain.

[0019] Among them, two calibration gauge measuring heads 3 set in front and behind each other constitute a measurement group, and the measurement group is set into nine groups.

[0020] Among them, one end of the compressed gas interface terminal 7 has nine interfaces that can be connected to nine gas and electricity meters. Through the nine sets of measurement groups arranged side by side, it is possible to put the workpiece under test in one go and complete the detection of nine parameters simultaneously, which greatly improves the detection efficiency.

[0021] Among them, the standard part 5 is located directly above the integrated positioning block 2. The standard part 5 is a high-precision reference block with known dimensions, and its dimensions represent the ideal state of the workpiece being measured.

[0022] The base 1 has four openings, which are arranged in pairs opposite each other about the base 1.

[0023] Among them, the front and rear calibration gauge heads 3 are arranged symmetrically about the standard part 5.

[0024] The nine measurement groups are arranged side by side.

[0025] Among them, multiple ventilation ports 6 are connected to one end of the compressed gas interface terminal 7 via connecting pipes.

[0026] The working principle and usage process of this utility model are as follows: First, connect the external compressed air source to the compressed gas interface terminal 7 at the bottom of the fixture. The compressed gas interface terminal 7 integrates all the air paths, realizing one-line access. At the same time, use nine air pipes to connect the nine outlets at the other end of the terminal to nine gas-electric meters respectively. Before starting the test, the fixture needs to be calibrated using the standard part 5. The operator places the standard part 5 in the designated position of the integrated positioning block 2. At this time, the gap between the nozzles of all nine calibration gauge heads 3 and the corresponding surfaces of the standard part 5 is at the preset ideal value. Observe the readings of the nine gas-electric meters and adjust or set them to zero or standard values. This step ensures the reference accuracy of the entire measurement system. Remove the standard part 5 and place the workpiece to be tested on the integrated positioning block 2. The integrated positioning block 2 serves as a unique and unchanging mechanical positioning reference, ensuring that the position and posture of the workpiece are exactly the same each time it is placed. This fundamentally eliminates the cumulative error caused by reference conversion or multiple clamping, which is the key to ensuring the consistency and reliability of the measurement results. Once the workpiece is in place, its nine test locations will simultaneously correspond to nine sets of measurement groups arranged side by side. Each measurement group consists of two calibration gauge probes 3 arranged one in front of the other, used to measure a specific parameter, such as the height of a plane or the width of a groove. Compressed gas enters from the interface terminal 7, is distributed to the nine air inlets 6 through the internal connecting pipe, and finally enters each calibration gauge probe 3. The nozzle at the end of the calibration gauge probe 3 will spray a stable airflow onto the workpiece surface. When the workpiece size is ideal, the gap between the nozzle and the workpiece surface is equal to the gap with the standard part during calibration. At this time, the airflow resistance is stable, and the gas-electric meter displays zero or the standard value. If the workpiece size deviates, this gap will change. If the gap becomes larger, the airflow will dissipate more easily, and the back pressure inside the probe will decrease. If the gap becomes smaller, the airflow will be more severely obstructed, and the back pressure inside the probe will increase. The operator can simultaneously observe the display screens of nine gas and electricity meters. The reading on each screen directly corresponds to the dimensional deviation of a parameter of the workpiece. Based on the preset tolerance zone, the operator can immediately determine whether each parameter is qualified. The contents not described in detail in this instruction belong to the prior art known to those skilled in the art.

[0027] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
