Description

Technical Field

[0001] This utility model relates to the field of ring forging production equipment, specifically to a tooling for inspecting threaded holes in ring forgings. Background Technology

[0002] The threaded holes on the end face of ring forgings are usually inspected using thread plug gauges. Thread plug gauges consist of a go gauge and a no-go gauge. The standard for a qualified thread in a threaded hole is that the go gauge can be screwed into the threaded hole and the no-go gauge cannot be screwed into the threaded hole. Whether the thread in a threaded hole is qualified is inspected by thread plug gauges. However, the inspection efficiency of the thread length and the depth of the threaded hole is low and the inspection is inconvenient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tooling for detecting threaded holes in ring forgings that can detect whether the thread is qualified and can quickly and accurately detect the length of the thread and the depth of the threaded hole.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a tooling for inspecting threaded holes in ring forgings, comprising: a thread plug gauge, which consists of a go gauge and a no-go gauge, with the go gauge located below the no-go gauge and the two arranged coaxially. The tooling is characterized by: two guide rails, an upper laser rangefinder, a lower laser rangefinder, and a depth measuring rod arranged between the go gauge and the no-go gauge. The two guide rails are parallel and pass through the left and right sides of the two laser rangefinders respectively. The two guide rails are perpendicular to the end faces of the go gauge and the no-go gauge respectively, and their ends are fixed to the go gauge and the no-go gauge respectively. The two laser rangefinders are guided by the two guide rails when moving up and down. The upper end of the depth measuring rod is fixed to the upper laser rangefinder, and the depth measuring rod passes downwards through... The lower laser rangefinder has a tapered lower end for its depth sensing rod. The upper laser rangefinder measures the distance between itself and the lower end face of the stop gauge. When the upper laser rangefinder is against the stop gauge, the distance between them is zero, and the lower end of the depth sensing rod is flush with the lower end face of the go gauge. The lower laser rangefinder measures the distance between itself and the upper end face of the go gauge. When the lower laser rangefinder is against the go gauge, the distance between them is zero. Support plates are provided on the left and right sides of the lower laser rangefinder. The support surfaces of the two support plates are flush with the lower measuring reference surface of the lower laser rangefinder. The two support plates can abut against the end face of the ring forging to support the lower laser rangefinder, preventing it from entering the threaded hole.

[0005] Furthermore, in the aforementioned ring forging thread hole inspection fixture, a locking knob is threadedly connected to one side of the upper laser rangefinder and the lower laser rangefinder respectively. When the locking knob is screwed in, it can press against the guide rail, thereby fixing the upper laser rangefinder and the lower laser rangefinder.

[0006] Furthermore, in the aforementioned ring forging thread hole inspection fixture, the depth detection rod is threadedly connected to the upper laser rangefinder.

[0007] Furthermore, in the aforementioned ring forging thread hole inspection fixture, the outer end of the support plate is rounded, and a weight-reducing elongated hole is provided on the support plate.

[0008] Furthermore, in the aforementioned ring forging thread hole inspection fixture, two guide rails are threadedly connected to a go gauge and a no-go gauge, respectively.

[0009] The advantages of this utility model are: the aforementioned ring forging thread hole inspection fixture can quickly detect whether the thread is qualified by using a go gauge and a no-go gauge, and can quickly and accurately detect the length of the thread and the depth of the thread hole by using two laser rangefinders and a depth measuring rod, which greatly improves the inspection quality and inspection efficiency.

[0012] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0013] like Figure 1 , Figure 2As shown, the tooling for inspecting threaded holes in ring forgings includes: a thread plug gauge, which consists of a go gauge 1 and a no-go gauge 2. The go gauge 1 is located below the no-go gauge 2, and the two are arranged coaxially. Between the go gauge 1 and the no-go gauge 2 are two guide rails 3, an upper laser rangefinder 4, a lower laser rangefinder 5, and a depth measuring rod 6. The two guide rails 3 are parallel and pass through the left and right sides of the two laser rangefinders respectively. The two guide rails 3 are perpendicular to the end faces of the go gauge 1 and the no-go gauge 2 respectively, and their ends are fixed to the go gauge 1 and the no-go gauge 2 respectively. The two laser rangefinders are guided by the two guide rails 3 when moving up and down. The upper end of the depth measuring rod 6 is fixed to the upper laser rangefinder 4, and the depth measuring rod 6 passes downward through the lower laser rangefinder 5. The lower end is set as a cone. The upper laser rangefinder 4 is used to detect the distance between it and the lower end face of the stop gauge 2. The upper laser rangefinder 4 abuts against the stop gauge 2. At this time, the distance between the two is zero. The lower end of the depth detection rod 6 is flush with the lower end face of the go gauge 1. The lower laser rangefinder 5 is used to detect the distance between it and the upper end face of the go gauge 1. The lower laser rangefinder 5 abuts against the go gauge 1. At this time, the distance between the two is zero. Support plates 7 are set on the left and right sides of the lower laser rangefinder 5. The support surfaces of the two support plates 7 are flush with the lower measuring reference surface of the lower laser rangefinder 5. The two support plates 7 can abut against the end face of the ring forging to support the lower laser rangefinder 5, so that the lower laser rangefinder 5 does not enter the threaded hole 10.

[0014] In this embodiment, a locking knob 8 is threaded onto one side of the upper laser rangefinder 4 and the lower laser rangefinder 5 respectively. When the locking knob 8 is screwed in, it can press against the guide rail 3, so that the upper laser rangefinder 4 and the lower laser rangefinder 5 can be fixed.

[0015] The depth sensing rod 6 is threadedly connected to the upper laser rangefinder 4. The lower conical tip of the depth sensing rod 6 will become dull after repeated use, requiring frequent replacement. The threaded connection facilitates this replacement. The outer end of the support plate 7 is rounded, and a long, narrow hole 9 for weight reduction is provided on the support plate 7. The two guide rails 3 are threadedly connected to the go gauge 1 and the no-go gauge 2, respectively. This arrangement facilitates the manufacturing of the tooling.

[0016] During inspection, the standard for acceptable thread quality in threaded holes is: GO gauge 1 can be screwed into threaded hole 10, and NO-GO gauge 2 cannot be screwed into threaded hole 10; For example... Figure 2As shown, the length of the thread and the depth of the threaded hole are detected as follows: The GO gauge 1 is screwed into the bottom of the thread in the threaded hole 10. The lower laser rangefinder 5 is placed on the end face of the ring forging via the support plates 7 on both sides. At this time, the distance between the lower laser rangefinder 5 and the upper end face of the GO gauge 1 can be directly read from the lower laser rangefinder 5, and the value is B. Therefore, the length of the thread in the threaded hole 10 is the thickness of the GO gauge 1 plus B. The upper laser rangefinder 4 is moved down until the lower end of the depth detection rod 6 abuts against the bottom center of the threaded hole 10. At this time, the distance between the upper laser rangefinder 4 and the lower end face of the no-go gauge 2 can be directly read from the upper laser rangefinder 4, and the value is A. Therefore, the depth of the threaded hole 10 is A + B + the thickness of the GO gauge 1.
