Abstract
The invention discloses an extension boring carriage structure, which comprises a flange connecting part (1), a middle sleeve body (2) and a tail support circular sleeve (3), wherein the surface of a flange of the flange connecting part (1) is provided with a countersunk holes (1a) for connecting, the countersunk holes (1a) isare uniformly distributed along the circumference of the surface of the flange, the tail support circular sleeve (3) is separated into a semicircular support sleeve (3a) and a semicircular compressing sleeve (3b), and the semicircular support sleeve (3a) can be separated from the integral body. The extension boring carriage structure has the advantages that the structure is simple and reasonable, and the structure strength is higher; a boring rod is supported, so the problems of deformation and vibration of the boring rod during boring can be effectively reduced, and further the precision of the boring rod is improved.
Description
Technical field
The invention belongs to the Machining Technology field, relate in particular to a kind of boring machine boring bar of boring major diameter slotted hole with extending the boring frame.
Background technology
Along with the development of mechanical 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 larger to the effect of boring bar in the Boring Process, can make boring bar produce larger amount of deflection and flexural deformation, and boring bar rotation running can cause larger vibration when being, reduce surface quality and the bore hole precision of boring processing, the service life of also having reduced lathe simultaneously.
Summary of the invention
Purpose of the present invention 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 invention 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, have counterbore at described two platforms; Have the screwed hole that is connected with the semicircular ring clamping sleeve at described semicircular ring support set horizontal plane, adopt screw fastening to be connected between described semicircular ring clamping sleeve and the semicircular ring support set.
Further, described middle body is divided into three sections, and internal diameter and the external diameter of three sections bodies reduce successively.
Further, the axiality scope between described flange connecting portion and the support annulus cover is 0.01 ~ 0.15 mm.
Further, the squareness tolerance between described flange connecting portion bottom surface and its axis is less than 0.01 mm.
The invention has the advantages that: the present invention is simple and reasonable, self has the very strong rigidity of structure; Simultaneously boring bar is supported, can effectively reduce even avoid boring bar in Boring Process flexural deformation and vibration problem, thereby improved the precision of bore hole.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is end support annulus cover schematic cross-section of the present invention.
Fig. 3 is that the present invention uses view.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1,2 and 3, structure of the present invention 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 at described semicircular ring clamping sleeve 3b, has the screwed hole 3a1 that is connected with the semicircular ring clamping sleeve at described semicircular ring support set 3a horizontal plane; Adopt screw fastening to be connected between semicircular ring clamping sleeve 3b and the semicircular ring support set 3a.Middle body 2 is divided into three sections, and external diameter and the internal diameter of three sections bodies reduce successively, and such structural design greatly reduces deadweight of the present invention, thereby has greatly reduced the amount of deflection that produces because of deadweight; Simultaneously such structure setting has higher rigidity, is difficult for producing flexural deformation.
The present invention is when concrete the use, flange connecting portion 1 is connected by screw and is fixed on the boring machine boss 4, boring machine boring bar 5 passes from boring bar support set of the present invention, and terminal semicircular ring clamping sleeve 3b is fixed on the holistic arch brace cover 3 of the upper formation of semicircular ring support set 3a by screw in compression boring bar 5.In order to make the present invention that higher precision be arranged in use, flange connecting portion 1 and the axiality that supports between the annulus cover 3 require at 0.01 ~ 0.15 mm.Squareness tolerance between flange connecting portion 1 bottom surface 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 quality and the precision of boring processing greatly improved.
