Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing inspection, in particular to an inner diameter detector. Background Technique

[0002] In traditional inner diameter inspection, micrometers, tool microscopes, all-round length comparators, vertical length gauges, vertical electro-optical gauges, pneumatic gauges, etc. are usually used. Usually, after measuring one inner diameter section, it is manually transferred to the next inner diameter section for measurement. Due to the particularity of the measurement of these devices, a large amount of preparation time is required. When detecting the inner diameter of a long pipe with a small inner diameter (inner hole diameter less than 2 mm), ordinary measuring tools cannot measure, and due to a large number of factors such as manual operation, environmental temperature, and tooling positioning, these factors will have an adverse impact on the measurement of multiple inner diameter sections of long pipe-shaped parts with small inner diameters, thus affecting the actual inspection results. Content of the Utility Model

[0003] To solve the problems raised in the above background technique, the purpose of the present utility model is to provide an inner diameter detector, which has the advantages of automatically detecting parts, reducing the generation of adverse effects, and improving the inspection results of parts, and solves the problem that the actual inspection results of parts are affected by factors such as manual operation during part inspection.

[0005] Preferably, a connecting plate is fixedly connected to the right side of the floating mechanism, and the connecting plate is movably connected to the probe lowering mechanism through bolts.

[0006] Preferably, a positioning hole is opened inside the bracket, and the positioning hole is movably connected to the base through bolts.

[0009] 1. By setting up a probe lowering mechanism and matching with different pneumatic measuring heads, the present utility model can not only measure multiple inner diameter cross-sections, mainly including small-diameter inner holes that cannot be measured by general equipment and methods, but also greatly reduce the participation of manual labor. Matching with a manipulator to place parts can achieve full-automatic detection, which can greatly reduce labor costs, improve detection efficiency, and complete the detection of multiple cross-sections of small inner diameters that cannot be completed by general detection.

[0026] Working principle and usage process of the utility model: Before starting the device, ensure that the pipe jacking 10 is in the falling state and the probe lowering mechanism 5 is at the high point. At this time, place the part to be detected into the positioning tooling 11, press the measurement start button 9, the probe lowering mechanism 5 will drive the floating mechanism 6 to descend, and at the same time drive the air measuring head 7 to slowly descend. The air measuring head 7 will enter the inner hole of the part to be detected, and the air measuring head 7 is electrically connected to the pneumatic measuring instrument 13. The air measuring head 7 and the probe lowering mechanism 5 are electrically connected to the control panel 3. The required measurement cross-section and interval can be set on the control panel 3. The probe lowering mechanism 5 will descend according to the operation instructions issued by the control panel 3. The air measuring head 7 starts to measure and obtains the inner diameter data of each cross-section based on the pneumatic measuring instrument 13 set on the control panel 3 and feeds it back to the control panel 3 for recording. After the part measurement is completed, press the stop button 2, the probe lowering mechanism 5 will rise to the high point again, and at the same time the air measuring head 7 will push out of the inner diameter of the part. Press the part button 8, and the part will be jacked out by the pipe jacking 10, thus completing the measurement effect of the part. Among them, the probe lowering mechanism 5 consists of a linear motion die, which can drive the floating mechanism 6 to rise or fall, so that the air measuring head 7 can move inside the part, and then cooperate with the control panel 3 to obtain multiple groups of measurement data. Secondly, the positioning tooling 11 consists of a set of precision positioning fixtures. When the part is placed inside the positioning tooling 11, the air pump 12 will drive the pipe jacking 10 to descend, so that the positioning tooling 11 can fix the part.
