Abstract
A radial cutting device for internal hole is composed of an elastic sleeve for the cutter rod, a slant boss in the gap at head of cutter rod, a cutter body with cutting blade passing through the gap and installed in the radial through hole at head of cutter rod sleeve, a slant slot matched with said slant boss at one side of cutter body, a thrust bearing, a thrust block and a nut. The utility model is suitable for a processing drill way is less, and the great work piece of downthehole machined surface diameter can realize advancing, going out smoothly of cutter arbor, cutter body to accomplish radial feed cutting in axial feed, thereby improve the work efficiency, reduce the processing cost, guarantee machining precision and uniformity.
Description
Technical field
The utility model relates to a kind of machining topping machanism, particularly a kind of topping machanism of realizing radially feed in endoporus.
Background technology
In the machining, it is less to tend to run into the aperture, and situation about will in the hole, cut on the big surface of revolution, for example, 475 diesel-engine body cylinder sleeves, there is one 2.5 * 45 ° inner conical surface its underpart, in order to the sealing hydrosphere to be installed, because inner conical surface aperture maximum gauge and minimum-value aperture, sleeve port top are almost equal, adopt the fixed common boring cutter structure of cutter head, be difficult to stretch into the accurate processing that realizes inner conical surface in the hole.As adopting axial feed, the two-way mobile machining tool that crosses feed again then obviously reduces work efficiency, increases processing cost, also influences machining accuracy.
The utility model content
The technical problems to be solved in the utility model is the weak point that overcomes existing common boring cutter structure, provide a kind of being used in to carry out on the common boring machine adding man-hour in the hole, in the knife bar axial feed, realize radially feed of cutter head simultaneously, thereby improve work efficiency and machining accuracy, the internal orifice dimension that cuts down finished cost is to topping machanism.
The technical solution of the utility model is: internal orifice dimension is to topping machanism, comprise knife bar and as the cutter hub of cutting tool, improvements are the flexible knife bar covers of knife bar peripheral hardware, become axial sliding fit between the two, and synchronous rotating mechanism arranged, knife rod head has the breach that cuts half, on the axial plane in the breach the oblique boss that becomes inclination alpha with the knife bar axis is arranged, the breach that described cutter hub crosses knife rod head is installed in the radial direction through hole of knife bar cover head, one side of cutter hub has the oblique groove that matches with above-mentioned oblique boss, between knife bar cover tail end and the knife bar root compression spring is arranged, there is thrust bearing knife bar cover afterbody shoulder inboard.
Further scheme is: the synchronous rotating mechanism of knife bar, knife bar cover is that the knife bar side has axial notch, and there is screw knife bar cover corresponding position, and the screw front end stretches in the groove, and the screw point diameter is consistent with recess width; The inclination alpha of oblique boss is 15 °～30 °; The cross section of oblique boss is a rectangle; Thrust bearing is provided with thrust block and pieces together jack panel towards a side of knife bar cover front end.
Adopt above technical scheme, this device is used for endoporus and adds man-hour, knife bar is fixed on the special-purpose boring head by screw, knife bar drives the rotation together of knife bar cover by screw or feather key, stretch into the workpiece endoporus jointly, when thrust block is run into the workpiece end face, the knife bar cover stops axially-movable, and knife bar continues to protract, at this moment, the oblique boss of knife rod head produces slip in the oblique groove of cutter hub, and the correct direction of its inclination alpha and rationally angle just in time force the cutting edge of cutter hub protruding, to realize the processing of the surface of revolution in the hole.After the completion of processing, knife bar withdraws from backward, and compression spring forces knife bar interplanting short stay, at this moment, cutter hub withdrawal origin-location, knife bar, knife bar cover withdraw from workpiece together.Before the processing,, adjust the thickness of thrust block, piece together tightly, determine the distance of thrust block bottom surface, calculated the out reach of cutter hub cutting edge simultaneously, to guarantee the dimensional accuracy of workpiece endoporus machined surface to the cutter hub center by nut according to workpiece size.
It is less that the utility model is used to process the aperture, and during the workpiece that the machined surface diameter is bigger in the hole, can realize knife bar, cutter hub smoothly into and out of, and in an axial feed, finish radially feed and cut, thereby the raising work efficiency reduces cost, and guarantees machining accuracy and uniformity.

Fig. 1 is the utility model structural representation;
Fig. 2 is an A-A place part sectioned view among Fig. 1;
Fig. 3 is a B-B place part sectioned view among Fig. 1.
The specific embodiment
As figure, knife bar 2 is provided with knife bar cover 6, and both become axial cunning to join, and its afterbody has compression spring 1, is fixed in screw 7 that knife bar puts and stretches in the axial notch 8 on the knife bar, and the knife bar cover is rotated synchronously with knife bar.There is thrust bearing 3 knife bar cover afterbody shoulder inboard, thrust block 4 and assembly jack panel 5.Knife rod head has the breach 9 that cuts half, and the oblique boss 13 that becomes inclination alpha=20 ° with the knife bar axis is arranged in the breach 9, and its cross section is a rectangle.Cutter hub 12 crosses in the radial direction through hole 10 that breach 9 is installed on knife bar cover head, and one-tenth is slidingly matched, and a side of cutter hub 12 has the oblique groove 14 that matches with oblique boss 13, and the head of cutter hub 12 has cutting edge 11.
