Problems solved by technology

[0002] During the machining process of engine parts, three checks are generally required to ensure that the dimensions meet the requirements of the drawings. At present, there is no good detection device for judging whether the R0.5mm small fillet of the thrust shaft cover meets the process requirements. Relying on visual inspection, this will easily cause measurement errors, which may cause the R angle to be too large, resulting in unqualified batch processing, and the large R angle will cause interference between the thrust plate and the fillet, causing related parts to not rotate or not to rotate smoothly , it is often necessary to disassemble the machine and rework the fillet of the thrust face, which affects the beat of the assembly line

specific Embodiment 1

[0020] like figure 1 As shown, a simple measurement tool for measuring the small fillet of the thrust shaft cover includes a measuring head 1 and a connecting rod 2, and the lower end of the measuring head 1 and the connecting rod 2 is connected by a connecting bolt 3; the end of the measuring head 1 It is a rounded corner measuring head, and the rounded side head matches the small rounded corner 13-1 of the thrust surface of the thrust shaft cover 13 to be tested. When in use, a bottom surface of the measuring head 1 fits the thrust shaft cover The outer circular surface 13-2 of the thrust surface of 13 is irradiated by a light source on one side of the measuring head 1, and the human eye observes the light leakage on the other side, and rotates a circle along the small rounded corner (the small rounded corner 13-1 is in the A circle is distributed on the thrust shaft cover, such as Figure 5 Shown) to judge the eligibility of small rounded corners.

specific Embodiment 2

[0021] like Figure 2-5 As shown, a simple measuring tool for measuring the small fillet of the thrust shaft cover includes a probe 1 and a connecting rod 2. The probe 1 includes a fillet probe, and the two sides of the lower part of the fillet probe are respectively distributed There are a light-blocking plate 1-31 and a light-blocking plate 1-32 matching the small rounded corners of the thrust surface of the thrust shaft cover. There is a light-sensitive empty groove 1-1 between the two light-blocking plates. A photosensitive element 1-2 is distributed in the photosensitive cavity 1-1; of course, this embodiment is also provided with a control circuit and a liquid crystal display module 12; the control circuit is connected to the photosensitive element 1-2 and the liquid crystal display A module 12, the liquid crystal display module 12 is used to display the time and light intensity value of the photosensitive element 1-2. In order to improve the sensitivity of the photosen...

Abstract

The invention discloses a simple measuring tool for measuring a small round corner of a thrust shaft cover. The measuring tool comprises a measuring head and a connecting rod. The measuring head is connected with the lower end of the connecting rod. The tail end of the measuring head is a round corner measuring head. Light baffles matched with the small round corner on a thrust face of the thrustshaft cover are distributed on two sides of the lower part of the round corner measuring head. A light sensing slot is formed between the two light baffles, and a light sensing element is distributedin the light sensing slot. According to the simple measuring tool for measuring the small round corner of the thrust shaft cover, quick detection can be performed on the small round corner on the thrust surface of the thrust shaft cover with an accurate detection effect and high efficiency.

Description

technical field [0001] The invention relates to the technical field of engine inspection tools, in particular to a simple measuring tool for measuring the small fillet of a thrust shaft cover. Background technique [0002] During the machining process of engine parts, three checks are generally carried out to ensure that the dimensions meet the requirements of the drawings. At present, there is no good detection device for judging whether the R0.5mm small fillet of the thrust shaft cover meets the process requirements. Relying on visual inspection, this will easily cause measurement errors, which may cause the R angle to be too large, resulting in unqualified batch processing, and the large R angle will cause interference between the thrust plate and the fillet, causing related parts to not rotate or not to rotate smoothly , It is often necessary to disassemble the machine and rework the fillet of the thrust face, which affects the beat of the assembly line. [0003] The di...
