Abstract
The utility model relates to a precision machining device for an actuating cylinder hole. The utility model adopts the technical scheme that the precision machining device comprises an oil stone, a connecting rod, a lock nut, an adjusting nut, a connecting pin, a tapered ejector rod and a connecting nut; the oil stone is mounted at one end of the connecting rod, one end of the ejector rod is mounted in a hole of the connecting rod, the other end of the connecting rod is inserted into the connecting nut after being connected with the lock nut and is in threaded connection with the connecting nut, the other end of the ejector rod is placed in the connecting nut, guide rails are symmetrically arranged on the connecting nut, the two ends of the connecting pin respectively extend out of the guide rails after the connecting pin penetrates through the ejector rod, the adjusting nut is in threaded connection with the connecting nut, and a handle is arranged on the adjusting nut. The precision machining device provided by the utility model has the benefits that through the precision machining device, precision machining can be carried out on the dimension and the roughness of the surface of the turned acting cylinder inner hole, and the effects that the dimensional precision of the internal diameter surface of a deep and long blind hole reaches the IT7-IT6 level, and the roughness Ra is not more than 0.2 mum are realized.
Description
Technical field
The invention relates to the device of surface of deep hole in the pressurized strut of a kind of Precision Machining small size.
Background technology
Working region, pressurized strut inner bore of part surface is conventionally to requirement on machining accuracy very high (IT 7-IT6) and surface roughness very little (Ra≤1.6), common machining process cannot be realized required precision, and the internal surface of hole of pressurized strut part mostly is enclosed construction, in process, not only need the roughness that guarantees piece surface to require also to guarantee not burnt in surface.At present, in the situation that there is no Special Equipment, need to solve the Precision Machining problem in pressurized strut hole.Therefore need a kind of pressurized strut precise processing device that can use on engine lathe.
Summary of the invention
In order to overcome the above problems, the invention provides one can utilize existing engine lathe, and precision machined device is carried out in surface, small size endoporus pressurized strut moving region.
To achieve these goals, the technical scheme that the invention adopts is: the precise processing device in a kind of pressurized strut hole, is made up of oilstone, connecting rod, locking nut, adjusting nut, connecting pin, push rod and attaching nut with tapering; Oilstone is installed in one end of connecting rod, one end of push rod packs in the hole of connecting rod, after the other end of connecting rod is connected with locking nut, insert in attaching nut, and be threaded with attaching nut, the other end of push rod is placed in attaching nut, on attaching nut, be arranged with guided way, connecting pin stretches out respectively guided way through two ends after push rod, and adjusting nut is threaded with attaching nut, and adjusting nut is provided with handle.
The beneficial effect of the invention is: the actual demand that the invention method of operating is simple, efficient, reliable, convenient, can effectively solve production.Can carry out Precision Machining to the size of pressurized strut bore area after turning and roughness by the invention, realize that profound blind hole inside diameter surface dimensional accuracy reaches IT 7-IT6 level and roughness Ra is not more than 0.2 μ m.The invention can utilize engine lathe to process small size pressurized strut internal diameter, also can in the situation that there is no Special Equipment, carry out Precision Machining to similar ultralong deep hole, eccentric orfice class and various aperture, reliable operation, and cost is low, profitable.

The specific embodiment
the precise processing device in a kind of pressurized strut of embodiment hole
As Figure 1-Figure 5, the precise processing device in a kind of pressurized strut hole, is made up of oilstone (1), connecting rod (2), locking nut (3), adjusting nut (4), connecting pin (5), push rod (6) and attaching nut (7) with tapering.
Oilstone (1) is installed in one end of connecting rod (2), the other end of connecting rod (2) is provided with external screw thread, one end of push rod (6) packs in the hole of connecting rod (2), locking nut (3) is connected with connecting rod (2) external screw thread, then connecting rod (2) is inserted in attaching nut (7), and be connected with attaching nut's (7) internal thread, with locking nut (3) by connecting rod (2) and attaching nut (7) locking, the other end of push rod (6) is placed in attaching nut (7), on attaching nut (7), be arranged with guided way (8), connecting pin (5) stretches out respectively guided way (8) through two ends after push rod (6), adjusting nut (4) is threaded with attaching nut (7), adjusting nut (4) is provided with handle (9).
When work, attaching nut (7) is connected with lathe, part to be processed rotates with the main shaft of lathe, pull the handle on adjusting nut (4), promote to be contained in connecting pin (5) on push rod (6) with adjusting nut (4) inner face mobile along guided way (8), thereby drive push rod (6) motion, according to the interior hole size of processing parts, adjust lift rod stroke, oilstone carries out micro cutting, burnishing-in, polishing, completes processing part with certain pressure.
Oilstone material can adopt carborundum.
