Abstract
Description
Technical Field
[0001] This utility model relates to the field of inspection tool technology, specifically an alloy three-parameter inspection tool. Background Technology
[0002] Inspection tools are simple testing tools used in industrial production to control parameters such as product aperture and spatial dimensions. They improve efficiency and quality in mass production scenarios through standardized processes and can replace traditional measuring tools such as plug gauges and calipers. Their core functions include part surface inspection, hole position verification, and dimensional evaluation. The main structure consists of a positioning device, a measuring device, and a fixture.
[0003] Existing inspection fixtures require workers to clamp, inspect, read, and record the workpiece sequentially on three independent, single-function fixtures before switching to the next fixture. This method is not only extremely inefficient, but the repeated clamping introduces positioning errors, affecting the consistency of the inspection results. Furthermore, the relative positions of the probes in existing parametric fixtures are usually fixed, meaning that each fixture can only be used to inspect a specific type of workpiece, making it unsuitable for different series or specifications of products. For companies producing a wide variety of products in small batches, this necessitates equipping a large number of dedicated fixtures, resulting in very high costs. Therefore, there is an urgent need for an alloy three-parameter fixture to solve the aforementioned technical problems. Utility Model Content
[0004] The purpose of this invention is to provide an alloy three-parameter inspection tool to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An alloy three-parameter gauge includes a base, an air inlet at the bottom of the base, a guide plate at the top center of the base, a positioning block on one side of the guide plate, a first external air measuring head on both the front and rear sides of the positioning block, a second external air measuring head on both the front and rear sides of the positioning block and to the right of the two first external air measuring heads, and a third external air measuring head on both the front and rear sides of the positioning block and to the right of the two second external air measuring heads. Each of the first, second, and third external air measuring heads has an air inlet, and a standard component is provided on the top of the positioning block.
[0006] As a preferred embodiment of this utility model, the number of guide plates is set to two, and the two guide plates are arranged symmetrically about the positioning block.
[0007] As a preferred technical solution of this utility model, the side calibration diameter of the first external gas measuring head is 13mm.
[0008] As a preferred embodiment of this utility model, the side calibration diameter of the second external gas measuring head is 24mm.

[0010] As a preferred technical solution of this utility model, the positioning block, the first external gas measuring head, the second external gas measuring head and the third external gas measuring head can all be axially moved and adjusted along the guide plate.
[0011] As a preferred technical solution of this utility model, the first external gas measuring head, the second external gas measuring head, and the third external gas measuring head are at the same horizontal height.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The positioning block and the first, second and third external gas measuring heads of this utility model can all be moved and adjusted axially along the guide plate. This design allows the inspection fixture to be flexibly configured according to the specific size of the workpiece, adapting to the inspection needs of alloy workpieces of different specifications, improving the versatility and applicability of the inspection fixture, reducing the frequency of changing tooling or special inspection fixtures, reducing costs and improving inspection efficiency.
[0014] This invention features three external calibration heads, each with a different side calibration diameter and the same horizontal height, enabling simultaneous detection of multiple external dimensional parameters of the workpiece. This integrated design allows for multi-parameter measurement to be completed in a single clamping operation, avoiding the cumbersome step-by-step detection process required by traditional gauges. This significantly improves detection accuracy and efficiency while reducing human error. Attached Figure Description

Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0018] Please see Figure 1-3 An alloy three-parameter inspection fixture includes a base 1, an air inlet 2 at the bottom of the base 1, a guide plate 7 at the top center of the base 1, a positioning block 6 on one side of the guide plate 7, a first external air measurement head 3 on both the front and rear sides of the positioning block 6, a second external air measurement head 4 on both the front and rear sides of the positioning block 6 and to the right of the two first external air measurement heads 3, and a third external air measurement head 5 on both the front and rear sides of the positioning block 6 and to the right of the two second external air measurement heads 4. Each of the first external air measurement head 3, the second external air measurement head 4, and the third external air measurement head 5 has an air inlet 8, and a standard part 9 is provided on the top of the positioning block 6.
[0019] The number of guide plates 7 is set to two, and the two guide plates 7 are arranged symmetrically about the positioning block 6.
[0020] The side calibration diameter of the first external air calibration head 3 is 13mm.
[0021] The side calibration diameter of the second external air calibration head 4 is 24mm.
[0022] The side calibration diameter of the third external gas measuring head 5 is 20mm.
[0023] The positioning block 6, the first external gas measuring head 3, the second external gas measuring head 4, and the third external gas measuring head 5 can all be axially moved and adjusted along the guide plate 7. This design allows the inspection fixture to be flexibly configured according to the specific size of the workpiece, adapting to the inspection needs of alloy workpieces of different specifications, improving the versatility and applicability of the inspection fixture, reducing the frequency of changing tooling or special inspection fixtures, reducing costs, and improving inspection efficiency.
[0024] Among them, the first external air measuring head 3, the second external air measuring head 4, and the third external air measuring head 5 are all at the same horizontal height. The three external air measuring heads are set up with different side calibration diameters and the same horizontal height. They can simultaneously detect multiple external dimensional parameters of the workpiece. This integrated design realizes the completion of multi-parameter measurement in one clamping, avoids the cumbersome process of step-by-step detection required by traditional inspection tools, significantly improves detection accuracy and efficiency, and reduces human error.
[0025] The number of air intake ports 2 is set to three.
[0026] In addition, all components in this technical solution are made of alloy materials.
[0027] The working principle and usage process of this utility model are as follows: First, connect the external compressed air pipeline to the three air inlet ports 2 on the base. Place the standard part 9 on the positioning block 6. The three diameters to be measured of the standard part 9 are aligned with the measurement positions of the first external air measuring head 3, the second external air measuring head 4, and the third external air measuring head 5. With the standard part 9 in place, introduce compressed air. By adjusting the pneumatic gauge connected to the air inlet 8 of each external air measuring head (not shown in the figure, but the pneumatic gauge is a standard and conventional component of the pneumatic measurement system and belongs to the existing technology in this field, so it will not be shown or described in detail), the reading of the instrument is set to the zero position or the reference value of the qualified range. This process establishes the reference correspondence between the size and the air pressure signal. Remove the standard part 9 and place the alloy workpiece to be tested in the same position on the positioning block 6. The two guide plates 7 form a guide rail to ensure that the workpiece can be pushed into the measurement position along the preset axis direction to achieve accurate positioning and avoid tilting or offset during measurement. When the workpiece is pushed into place, a tiny gap will be formed between its three outer circular surfaces to be measured and the measuring nozzles of the corresponding three pneumatic measuring heads. The size of this gap directly reflects the diameter of the workpiece at that point. The operator can make a judgment immediately by observing the readings of the three pneumatic measuring instruments. Positioning block 6, first external gas measuring head 3, second external gas measuring head 4, and third external gas measuring head 5 can all be axially moved and adjusted along guide plate 7. This design allows the fixture to be flexibly configured according to the specific size of the workpiece, adapting to the inspection needs of alloy workpieces of different specifications, improving the versatility and applicability of the fixture, reducing the frequency of changing tooling or special fixtures, reducing costs, and improving inspection efficiency. The three external gas measuring heads are set up, each with a different side calibration diameter and the same horizontal height, which can simultaneously detect multiple external dimensional parameters of the workpiece. This integrated design realizes the completion of multi-parameter measurement in one clamping, avoiding the cumbersome process of step-by-step inspection required by traditional fixtures, significantly improving inspection accuracy and efficiency, and reducing human error. The contents not described in detail in this specification are prior art known to those skilled in the art.
[0028] 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. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
