The utility model discloses a tool for processing the inner circle of a thin-walled cylinder with a large diameter. In order to solve the problem that the large-diameter thin-walled cylinder is easily deformed during processing, the inner circle processing tooling of the large-diameter thin-walled cylinder includes a tooling body composed of a plurality of arc plates, and the inner diameter of the tooling body with a round hole is the same as the diameter of the tooling body to be processed. The outer diameter of the large-diameter thin-walled cylinder is uniform; one end of each arc plate has a claw that is convenient for the lathe chuck to fix the tooling body. The utility model solves the problems of clamping deformation of a large-diameter thin-walled cylinder, difficult clamping, unstable clamping, and slow heat dissipation. The process is simple, safe and reliable, and the operation is convenient.
Description
Technical field
The utility model relates to machine components jig Design field, is specially a kind of large-caliber thin-walled cylinder inner circle processing tool.
Background technology
In mechanical field, jig Design is particularly important, is the key technology of strength member processing, and its general complex procedures, required precision is higher, and a large amount of man power and materials are also saved in the success or failure that rationally not only determined project of its design.
Large diameter thin wall cylindrical shell is processed and is had a following difficult problem on lathe:
1, due to the fastening difficulty of the thin clamping of workpiece wall, during clamping, easily produce distortion, even machine after unclamping clamping, also there will be certain elastic deformation amount, cause workpiece defective or directly scrap.
2, dynamics can not be excessive during Workpiece clamping, crosses conference and make workpiece deformation, and too small workpiece easily departs from fastening in process, occurs security incident.
3, in process, workpiece also needs to bear certain extruding force except bearing normal cutting force, makes the workpiece work in-process state in strain always, and processing dimension is difficult to guarantee.
4, in process, can produce a large amount of heats, because thin-wall part rigidity is not enough, cause workpiece is the state in continuous variation in process always, and size is difficult to control, and final size is difficult to ensure.
5, because workpiece work in-process exists distortion all the time, make process velocity slack-off, cutter loss strengthens, and precision is difficult to control, and processing cost improves.
Therefore, need the processing tool of a kind of large diameter thin wall cylindrical shell of exploitation badly.
Utility model content
In order to develop a kind of processing tool of large diameter thin wall cylindrical shell, the utility model aims to provide a kind of large-caliber thin-walled cylinder inner circle processing tool, and this processing tool can be processed the inner circle of large diameter thin wall cylindrical shell easily, prevents barrel distortion.
To achieve these goals, the technical scheme that the utility model adopts is:
A large-caliber thin-walled cylinder inner circle processing tool, its design feature is, comprises by polylith arc plate and is spliced to form the round-meshed frock body of tool, the interior circular diameter of this frock body is consistent with the external diameter of large-caliber thin-walled to be processed; One end of every block of arc plate has the claw of being convenient to lathe chuck fixing tool body.
Be below the technical scheme of further improvement of the utility model:
In order to improve the intensity of arc plate, prevent further barrel distortion, described every block of arc plate is provided with deep floor.
Preferably, described every arc plate internal face has escape.
According to embodiment of the present utility model, described frock body is comprised of three arc plate splicings.
Compared with prior art, the beneficial effects of the utility model are: the utility model is applicable to the inner circle processing of large diameter thin wall cylindrical shell, have solved large diameter thin wall cylindrical shell clamping distortion, clamping difficulty, clamp unstable, the slow difficult problem of dispelling the heat, operation is simple and safe reliable, controls conveniently.
Below in conjunction with drawings and Examples, the utility model is further elaborated.

The specific embodiment
In order to make of the present utility modelly to realize technological means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of large-caliber thin-walled cylinder inner circle processing tool, according to the selected scroll chuck model of large diameter thin wall cylindrical shell necessary requirement, with the wild card on chuck, change system into shape as shown in Figure 3, and assurance meets the demand of processing thin-walled cylindrical shell, claw 6 internal faces are reserved certain allowance, reduce the gap between claw 6 and claw after clamping as far as possible.
Three blocks of arc plates 4 after making and claw 6 are loaded on lathe chuck, form frock 2, process inner circle and escape, the interior circular diameter that guarantees claw 6 is consistent with the cylindrical of thin-wall barrel 3, thin-wall barrel 3 can be fitted tightly with claw after clamping, and increasing friction force, thin-wall barrel 3 work in-processes can not be shifted and produce distortion, and can improve workpiece radiating effect, make thin-wall barrel 3 work in-processes obtain best environment.
Clamping thin-wall barrel, processes and obtains finished product as shown in Figure 2.
The content that above-described embodiment is illustrated should be understood to these embodiment only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
