Abstract
The utility model discloses a numerically-controlled processing device for shielding case type thin-walled parts. The numerically-controlled processing device comprises a part carrier and a clamping sleeve, wherein the part carrier comprises a main body; the left side of the main body is provided with a connecting round platform, and the right side of the main body is provided with a positioning round platform; the clamping sleeve is locked on the circumference of the main body spirally; the clamping sleeve enwraps the positioning round platform inside the clamping sleeve; and a shielding case is clamped between the main body and the clamping sleeve, and sleeved on the circumference of the positioning round platform. When a part is mounted and clamped by applying the device, as the radial clamping force to the part is changed into axial clamping force, and the workpiece is not directly clamped, the deformation of the workpiece is reduced, and the problem of high possibility for deformation of parts caused by the situation that a three-jaw chuck is used for directly mounting and clamping the thin-walled parts is solved, the processing technology flow of the parts is simplified, the mounting and clamping as well as positioning operation is simple and convenient and feasible, the processing efficiency is improved, and the most important of all is that the processing quality of the parts is ensured, by tracking measurement, the common difference is basically controlled between 0.02 mm and 0.03 mm, and qualified parts are provided for manufacturing of high-voltage switch equipment.
Description
Technical field
The utility model relates to a kind of frock, particularly a kind of numerical control processing apparatus for processing radome class thin-walled parts.
Background technology
The processing of thin wall component is the processing difficult problem that mechanical processing industry exists all the time; The kernel component radome of high-tension switch gear isolating switch is characterized in that wall is thin, and wall thickness is only 3 ~ 5mm, mutability, and size is wayward, and because bore portion in it has the shrink fit size, tolerance is high again, substantially will be controlled in 0.05mm.If adopt the direct installation way processing of common scroll chuck, after machining on lathe, in case unclamp claw, the deflection of part can't guarantee the accessory size machining accuracy in the 0.3mm left and right.
The utility model content
The purpose of this utility model is to provide a kind of numerical control processing apparatus for radome class thin-walled parts, to solve the problems of the technologies described above.
To achieve these goals, the utility model adopts following technical scheme:
A kind of numerical control processing apparatus for radome class thin-walled parts comprises part carrier and gripping sleeve; The part carrier comprises main body, and main body left side is provided with the connection round platform, and the main body right side is provided with positioning round table; The gripping sleeve screw lock is in the main body periphery, and gripping sleeve is surrounded in it positioning round table.
The utility model further improves and is: the gripping sleeve cylindrical is provided with reticulate pattern.
The utility model further improves and is: the gripping sleeve cylindrical is provided with the spanner hole.
The utility model further improves and is: radome is held between main body and gripping sleeve, and is placed in the positioning round table periphery.
The utility model further improves and is: the fit clearance control between the endoporus of positioning round table and radome is less than 0.05mm.
compared with prior art, the utlity model has following advantage: use this device clamping parts, be axial chucking power by the radially chucking power that changes part, not direct holding workpiece, reduce the deflection of workpiece, solved the direct clamping thin wall component of use scroll chuck, make the easily deformable problem of part, simplified the processing process of such part, clamping and positioning action are all simple and easy to do, improved working (machining) efficiency, the most important thing is to guarantee the crudy of such part, through tracking measurement, its tolerance basic controlling is between 0.02mm ~ 0.03mm, for the manufacturing of high-tension switch gear provides qualified parts.
Description of drawings
Fig. 1 is the structural representation of device of the present utility model.
In Fig. 1: 1, part carrier, 11, connect round platform; 12, positioning round table; 2, gripping sleeve, 3, radome.
The specific embodiment
Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
See also shown in Figure 1ly, a kind of numerical control processing apparatus for radome class thin-walled parts of the utility model comprises part carrier 1 and gripping sleeve 2; Part carrier 1 comprises main body and is connected the connection round platform 11 in main body left side, is arranged at the positioning round table 12 on main body right side, and the main body periphery is provided with external screw thread; Connect round platform 11 and be used for adding connecting the lathe three-claw chuck man-hour, positioning round table 12 is used for adding man-hour radome 3 to be mounted thereon positioning; Positioning round table 12 is controlled in 0.05mm with the endoporus fit clearance of radome 3, after radome 3 is positioned positioning round table 12, the periphery of using gripping sleeve 3 to be threadedly connected to part carrier 1 clamps radome 3, part carrier 1 and gripping sleeve 2 are taked threaded connection mode, gripping sleeve 2 cylindricals are provided with reticulate pattern, increasing cylindrical frictional force, and be equipped with the spanner hole, so that loading and unloading.By this device, realize the processing of the interior hot pressing size of this type of thin-walled parts.
During processing radome class thin-walled parts, first process by normal turner processing method, guarantee overall length, cylindrical, interior step circle and the inside groove size of part, shrink fit size diameter direction made allowance 1.5mm.After processing above-mentioned all process steps, can process the hot pressing size.At first the left side in part carrier 1 shown in Figure 1 is connected round platform 11 clampings in the scroll chuck of lathe, again with radome 3 clampings on the positioning round table 12 of part carrier 1, making it axially reach radial position determines, in order to determine the coordinate figure of part in digital control processing, then gripping sleeve shown in Figure 12 be tightened on part carrier 1.So just, complete the clamping of part, then just can carry out the processing of this inner bore of part hot pressing size.This clamping structure is converted into axial clamping direction with traditional radially method of clamping to part, can avoid the radial force of part, makes the part work in-process not yielding, thereby has guaranteed the requirement on machining accuracy of such part.
