Abstract
The utility model discloses an extending boring frame structure which comprises a flange connecting part (1), a middle sleeve body (2) and a tail end supporting ring sleeve (3), wherein countersinking holes (1a) which are used for connection are formed in a flange surface of the flange connecting part (1) and are circumferentially distributed, the tail end supporting ring sleeve (3) is divided into a half-ring supporting sleeve (3a) and a half-ring pressing sleeve (3b), and the half-ring pressing sleeve (3b) can be separated from the whole extending boring frame structure. The extending boring frame structure has the advantages of simple and reasonable structure and strong structural stiffness, and when the extending boring frame structure is used for supporting a boring bar, the problems of bending deformation and vibration of the boring bar in a boring process can be effectively solved even avoided, thereby increasing the boring precision.
Description
Technical field
The utility model belongs to the Machining Technology field, and the boring machine boring bar that relates in particular to a kind of boring major diameter slotted hole is with extending the boring frame.
Background technology
Along with Development in Machine Industry, in mechanical processing process, often run into the phenomenon of some major diameter slotted holes of processing.Because boring bar is as the wall that overhangs, and when boring major diameter slotted hole; The length of stretching out is longer, cutting force is bigger to the effect of boring bar in the boring process, can make boring bar produce bigger amount of deflection and flexural deformation, and boring bar rotation running can cause bigger vibration when being, reduce the surface quality and the bore hole precision of boring processing, the service life of also having reduced lathe simultaneously.
Summary of the invention
The purpose of this utility model is for solving the shortcoming of prior art, provides a kind of rational in infrastructure simple and can guarantee the extension boring frame of the axial precision of boring bar.
For solving the problems of the technologies described above, concrete technical scheme of the present utility model is as follows:
A kind of extension boring shelf structure is characterized in that: comprise flange coupling part, middle body, end support annulus cover;
Have the counterbore that connects usefulness on the flange surface of described flange coupling part, described counterbore is circumference uniform distribution;
Described end support annulus cover is divided into semicircular ring support set and semicircular ring clamping sleeve, and described semicircular ring clamping sleeve can be realized separating with integral body.
Further, cut two platforms of horizontal symmetrical on the described semicircular ring clamping sleeve arc surface, on described two platforms, have counterbore; On described semicircular ring support set horizontal plane, have the screwed hole that is connected with the semicircular ring clamping sleeve, adopt screw to be fastenedly connected between described semicircular ring clamping sleeve and the semicircular ring support set.
Further, described middle body is divided into three sections, and the internal diameter and the external diameter of three sections bodies reduce successively.
Further, the axiality scope between described flange coupling part and the support annulus cover is 0.01 ~ 0.15 mm.
Further, the squareness tolerance between described bottom surface, flange coupling part and its axis is less than 0.01 mm.
The utility model advantage is: the utility model is simple and reasonable, self has the very strong rigidity of structure; Simultaneously boring bar is supported, can reduce even avoid boring bar effectively, thereby improved the precision of bore hole in flexural deformation of boring process and vibration problem.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the utility model end support annulus cover schematic cross-section.
Fig. 3 is the utility model user mode schematic diagram.
The specific embodiment
Come the utility model is further described below in conjunction with accompanying drawing.
Shown in Fig. 1,2 and 3, structure of the present utility model comprises flange coupling part 1, middle body 2 and end support annulus cover 3.Have the counterbore 1a of the connection usefulness that is circumference uniform distribution on 1 flange surface of described flange coupling part.Described end support annulus cover 3 is divided into semicircular ring support set 3a and semicircular ring clamping sleeve 3b, and described semicircular ring clamping sleeve 3b can realize separating with integral body; Cut two platform 3b1 of horizontal symmetrical on the semi arch clamping sleeve 3b arc surface, the setting of two platforms is convenient to have the counterbore 3b2 that connects usefulness on described semicircular ring clamping sleeve 3b, has the screwed hole 3a1 that is connected with the semicircular ring clamping sleeve on described semicircular ring support set 3a horizontal plane; Adopt screw to be fastenedly connected between semicircular ring clamping sleeve 3b and the semicircular ring support set 3a.Middle body 2 is divided into three sections, and the external diameter and the internal diameter of three sections bodies reduce successively, and such structural design greatly reduces deadweight of the present utility model, thereby has reduced the amount of deflection that produces because of deadweight greatly; Such structure setting simultaneously has higher rigidity, is difficult for producing flexural deformation.
The utility model is when concrete the use, flange coupling part 1 is connected and fixed on the boring machine boss 4 by screw, boring machine boring bar 5 passes from the utility model boring bar support set, and terminal semicircular ring clamping sleeve 3b is fixed on semicircular ring support set 3a by screw in compression boring bar 5 and goes up the holistic annulus support set 3 of formation.In order to make the utility model that higher precision be arranged in use, flange coupling part 1 and the axiality that supports between the annulus cover 3 require at 0.01 ~ 0.15 mm.Squareness tolerance between 1 bottom surface, flange coupling part and its axis is less than 0.01.Boring machine is when carrying out boring, cutter produces active force to boring bar 5, impels boring bar 5 flexural deformations, and the 3 pairs of boring bars of boring bar support set end support annulus cover 5 that are connected on the boring machine boss 4 support, the distortion of restriction boring bar 5, thus the quality and the precision of boring processing improved greatly.
