Ring gear refers in Planetary Gear Transmission, the internal gear with the same axis of planet carrier, in the detection of ring gear, The diameter of ring gear is the most important thing, and it is unqualified that the excessive ring gear that may directly result in of error occurs in diameter, therefore in production, The diameter of ring gear detect particularly important, the outer ring measuring device of ring gear is a kind of race diameter measurement of ring gear Detection device.
According to Chinese invention patent (CN201810718978.X), which discloses a kind of diameter ring gear measurement work Tool, which is accurately positioned gear ring by setting scroll chuck, column and locating slot, thus keep measurement data accurate, Although the measuring tool structure is simple, need to be not convenient to use by artificial repeatedly manual operation when in use.
Utility model content
The purpose of this utility model is to provide a kind of outer ring measuring devices for ring gear, to solve above-mentioned background skill The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions: a kind of outer ring measurement dress for ring gear It sets, including bottom plate, the upper surface of the bottom plate is fixedly installed with loop bar, and one end of the loop bar is plugged with motion bar, the work Lever is slidably connected with the loop bar, and the motion bar one end and the loop bar far from the loop bar are far from the motion bar One end is fixedly installed with fixture, and the graduated scale being fixedly connected with the bottom plate, the scale are provided with above the fixture It is fixedly installed with fixed mark corresponding with the fixture on the loop bar on ruler, is provided with and the activity on the graduated scale The corresponding vernier of the fixture on bar, the vernier are fixedly connected with the graduated scale, and the loop bar is internally provided with bullet Spring, the both ends of the spring are fixedly connected with the loop bar and the motion bar respectively.
Preferably, the upper surface of the bottom plate corresponds to and is fixedly installed with connecting column at the position at the both ends of the graduated scale a。
Preferably, the middle position of the fixture is arcuation corresponding with the outer ring of ring gear.
Preferably, there are two the motion bar and the loop bar are set altogether, two motion bars and two loop bars one A pair should be symmetrically mounted between two fixtures.
Preferably, connecting column b is provided on the fixture, the fixed mark passes through institute with the fixture on the loop bar It states connecting column b to be fixedly connected, the vernier is fixedly connected with the fixture on the motion bar by the connecting column b.
Compared with prior art, the utility model has the beneficial effects that
1, the outer ring measuring device of the ring gear is the fixture of arcuation by the way that setting is intermediate, to make the outer wall of gear ring and tight Patch, so that ring gear be fixed, and then accurately measures the race diameter of ring gear, is effectively prevented from when in use because in Gear ring, which is not fixed, causes measurement data inaccurate, reduces measurement error;
2, the outer ring measuring device of the ring gear is acted on by setting loop bar, motion bar and spring by the elastic force of spring, So that motion bar is mobile with one section of motion bar of fixture, so that ring gear be fixed, carried out without using auxiliary tool It is fixed, data can be directly read, it is easy to use.
Detailed description of the invention

Fig. 2 is the overlooking structure diagram of the utility model;
Fig. 3 is the attachment structure schematic diagram of loop bar and motion bar in the utility model;
In figure: 1, bottom plate;2, motion bar;3, loop bar;4, fixture;5, connecting column a;6, fixed mark;7, graduated scale;8, it swims Mark;9, connecting column b;10, spring.
Specific embodiment
The utility model is further described below with reference to embodiment.
The following examples illustrate the utility model, but cannot be used to limit the protection scope of the utility model.Implement Condition in example can be adjusted according to actual conditions are further, to the utility model under the concept thereof of the utility model Method simple modifications belong to the requires of the utility model protection range.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of outer ring measuring device for ring gear, Including bottom plate 1, the upper surface of bottom plate 1 is fixedly installed with loop bar 3, and one end of loop bar 3 is plugged with motion bar 2, motion bar 2 and loop bar 3 are slidably connected, and the one end of one end and loop bar 3 far from motion bar 2 of motion bar 2 far from loop bar 3 is fixedly installed with fixture 4, folder The top of tool 4 is provided with the graduated scale 7 being fixedly connected with bottom plate 1, and it is right with the fixture 4 on loop bar 3 to be fixedly installed on graduated scale 7 That answers fixes mark 6, and vernier 8 corresponding with the fixture 4 on motion bar 2, vernier 8 and the fixed company of graduated scale 7 are provided on graduated scale 7 It connects, loop bar 3 is internally provided with spring 10, and the both ends of spring 10 are fixedly connected with loop bar 3 and motion bar 2 respectively.
Wherein, the upper surface of bottom plate 1, which corresponds to, is fixedly installed with connecting column a5 at the position at the both ends of graduated scale 7, pass through Graduated scale 7 is supported on the top of bottom plate 1 by connecting column a5, will be had certain space between graduated scale 7 and fixture, is avoided scale The fixation of the influence ring gear of ruler 7.
Wherein, the middle position of fixture 4 is arcuation corresponding with the outer ring of ring gear, uses centre for the fixture of arcuation 4, so that the inner wall of fixture 4 be made to be close to the appearance wall of ring gear, and then ring gear is made to keep stablizing, avoids the internal tooth in measurement Circle movement, influences measurement data.
