In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0039] The present application will be described below with reference to the accompanying drawings and specific embodiments.

[0040] By providing a shaft flange boring machine in the embodiments of the present application, the technical problems in the prior art of poor positioning accuracy in the construction of reaming the shaft flange and easy scratching of the bolt holes are solved.

[0041] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations on the technical solution of the present application. Without conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0042] See Figure 1 , a shaft flange boring machine, which can limit the degree of deflection of the central axis of the boring bar 300, improve the positioning accuracy of the boring bar 300, and ensure that the distance between the inner wall of the bolt hole and the boring bar 300 can be maintained stably during disassembly, so as to avoid scratching and pulling the bolt hole.

[0043] Specifically, the shaft flange boring machine includes: a boring bar fixing tooling 100, a positioning sleeve 200, a boring bar 300, a boring tool 310, and a boring bar driving and feeding assembly 500. Among them, the boring bar driving and feeding assembly 500 serves as a power assembly, which is used to provide torque and axial moment, and drive the boring bar 300 and the boring tool 310 thereon to move axially and rotate circumferentially, so as to axially drive the boring bar 300 to gradually finish machining the bolt hole along the bolt hole on the shaft flange plate 610.

[0044] The boring bar 300 is rotatably arranged on the boring bar fixing tooling 100, so that the boring bar 300 is rotatably supported by the boring bar fixing tooling 100, and the amplitude of the radial swing of the boring bar 300 is restricted, thereby ensuring the machining accuracy of the boring bar 300. At the same time, when the boring bar 300 is disassembled, the inner wall of the bolt hole can be prevented from being scratched and damaged.

[0045] Meanwhile, the positioning sleeve 200 can be slidably sleeved on the boring bar 300, so as to serve as a positioning reference. That is, during the boring hole preparation operation, the positioning sleeve 200 is sleeved outside the boring bar 300, and the positioning sleeve 200 is pushed into the bolt hole formed by reaming on the shaft flange 310, so that a consistent gap is maintained between the circumferential surface of the boring bar 300 and the inner circumferential surface of the bolt hole, and a stable distance is maintained between the side wall of the boring bar 300 and the inner wall of the flange hole. At this time, the central axis of the boring bar 300 is basically consistent with the central axis of the bolt hole, thereby improving the quality and efficiency of the finish machining of the boring bar 300 and the boring tool 310. At the same time, when the boring bar 300 is disassembled after the machining is completed, the boring bar 300 can maintain a distance from the inner wall of the bolt hole, avoiding scratching and damaging the inner wall surface of the bolt hole.

[0046] In order to effectively control the opening specification, the boring tool 310 is detachably arranged on the boring bar 300, so that the specification of the boring tool 310 can be flexibly adjusted.

[0047] Therefore, through the cooperation of the positioning sleeve 200 and the boring bar fixing tooling 100, the boring bar 300 can be positioned with high precision and the distance between the boring bar 300 and the inner wall surface of the bolt hole can be maintained, avoiding damaging the inner wall surface of the bolt hole. At the same time, the operation efficiency is improved.

[0048] See Figure 5 , the positioning sleeve 200 includes: a positioning cylinder body 210; the specification of the positioning cylinder body 210 can meet the requirement that it can be stably embedded in the bolt hole while maintaining a small gap between the two. Generally speaking, its specific specification can be selected according to the inner diameter of the actual bolt hole, but the distance between the positioning cylinder body 210 and the inner wall surface of the bolt hole should be less than or equal to 0.02 mm. After the positioning sleeve 200 is installed in the bolt hole, the maximum deviation between the center line of the positioning sleeve 200 and the center line of the bolt hole is not greater than 0.02 mm. By arranging the positioning sleeve 200 at the head and tail of the bolt hole, the coincidence of the center line of the boring bar and the center line of the bolt hole is realized.

[0049] In order to facilitate operation and maintain the state, a radially protruding limit boss 220 is arranged on the outer peripheral surface of the positioning cylinder body 210, which can be abutted against the end surface of the bolt hole through the limit boss 220, so as to be stably arranged at the end of the shaft flange 310. For the convenience of disassembly and assembly operation, a radial flange 230 can be further arranged at the tail end of the positioning cylinder body 210 for easy holding.

[0050] On the other hand, for the convenience of disassembling, installing and replacing the boring tool 310, an embedded boring tool groove is formed on the boring bar 300, and the boring tool 310 is detachably arranged in the embedded boring tool groove.

[0051] It should be noted that the power structure for boring mainly lies in being able to provide torque output and axial moment output, so as to drive the boring bar 300 to rotate and at the same time be able to achieve axial pushing, so as to meet the axial pushing and axis rotation requirements of the boring bar 300.

[0052] Based on this, the boring bar driving and feeding assembly 500 includes: a spindle box 510, a servo motor 520, a speed reducer and a feed box 530; the output rotating shaft of the spindle box 510 is connected to the boring bar 300, the servo motor 520 is connected to the spindle box 530 through the speed reducer, and the feed box 530 is connected to the spindle box 510, so as to realize the output of driving torque for boring operation. Of course, there may be other implementation manners for such a driving structure, and the present application does not make any limitations.

[0053] In order to absorb the assembly connection error and reduce its influence on the boring accuracy and radial swing amplitude, the shaft flange boring machine further includes: a universal coupling 400; the output rotating shaft of the spindle box 510 is connected to the boring bar 300 through the universal coupling 400, so that there can be a certain deviation between the central axis of the boring bar 300 and the central axis of the output rotating shaft of the spindle box 510, without causing the deviation of the central axis of the boring bar 300 to affect the boring accuracy and scrape and damage the inner wall of the bolt hole.

[0054] In this embodiment, a fixing tooling that can be fixed to the shaft flange 600 is provided, and boring operation is carried out with it as the force application reference, so as to be able to form a boring basis with the shaft flange 600 as the unified reference, and avoid the influence of the matching error between different bases on the boring accuracy.

[0055] Specifically, the boring bar fixing tooling 100 includes: a fixing mechanism and a positioning bearing; the positioning bearing is arranged on the fixing mechanism; the boring bar 300 is rotatably arranged in the positioning bearing, so as to be able to rotatably support the boring bar 300 through the positioning bearing to limit its swing amplitude and ensure the accuracy.

[0056] Generally, the number of the positioning bearings is two, that is, the two positioning bearings can be arranged on both sides of the shaft flange 610, so as to limit the swing amplitude of the boring bar 300 through two rotatable fulcrums and ensure its accuracy; and with the cooperation of the universal coupling 400, while coordinating the torque output, the boring accuracy can also be ensured.

[0057] See Figure 2, Figure 3 and Figure 4 To facilitate adaptation to the morphological structure of the shaft body of the shaft flange 600 and ensure stable and reliable fixation, the fixing mechanism includes: an upper bottom plate 110, a lower bottom plate 180, a vertical plate 120, and a longitudinal pull rod 130.

[0058] Connect the upper bottom plate 110 and the lower bottom plate 180 through the longitudinal pull rod 130 to form a ring frame structure, thereby sleeving on the shaft body of the shaft flange 600 to achieve stable pressing and fixation.

[0059] The vertical plate 120 is fixed on the upper bottom plate 110, and a boring bar passing window 121 is provided on the vertical plate 120 for accommodating the boring bar 300; the positioning bearing is fixed on the vertical plate 120, and the axial end of the positioning bearing faces the window through which the boring bar 300 passes, so as to correspond to the reamed hole 611 provided on the shaft flange plate 610 to perform finish machining of the screw hole.

[0060] That is to say, the upper bottom plate 110 and the lower bottom plate 180 respectively abut against the circumferential surface of the shaft body of the shaft flange 600 to achieve stable surface-to-surface contact support, providing a stable support base structure for the positioning bearing and the boring bar 300.

[0061] To facilitate disassembly and assembly, a U-shaped groove 111 is provided on the upper bottom plate 110, so that one end of the pull rod 130 can be directly clamped in place, and the other end of the pull rod 130 is fixed on the lower bottom plate 180 through a screw and nut pair fixing member, improving the operation convenience.

[0062] The pull rod 130 can adopt a lead screw to improve the operation convenience.

[0063] To be able to adjust the position and attitude of the support base structure and ensure the reliability of the adjustment and maintenance of its central axis, through holes penetrating the plate surfaces are respectively provided on the upper bottom plate 110 and the lower bottom plate 180, and positioning adjustment bolts are screwed in the through holes for adjusting bolts, that is, the first positioning adjustment bolts 140 provided on the upper bottom plate 110. By abutting the two first positioning adjustment bolts 140 against the circumferential surface of the shaft flange 600, three-point support positioning of the upper bottom plate 110 is achieved to ensure the attitude and contact position of the upper bottom plate 110; similarly, the second positioning adjustment bolts 190 provided on the lower bottom plate 180, by abutting the two second positioning adjustment bolts 190 against the circumferential surface of the shaft flange 600, three-point support positioning of the lower bottom plate 180 is achieved to ensure the attitude and contact position of the lower bottom plate 180. Generally, to ensure the reliability of fixation, the upper bottom plate 110 and the lower bottom plate 180 can be arranged in parallel, so that the support structure is evenly stressed and its structure is stable and reliable.

[0064] On the other hand, by being fixed on the shaft body in a surface-to-surface contact manner, the upper bottom plate 110 and the lower bottom plate 180 can adapt to various specifications of the shaft body; of course, under the condition of known shaft body specifications, arc surfaces that match each other are provided on the upper bottom plate 110 and the lower bottom plate 180 to achieve stable adaptive nested support and improve the support reliability. Of course, this needs to be flexibly set according to actual operation requirements.

[0065] In order to adapt to two positioning bearings, two fixing mechanisms are arranged oppositely, and the two fixing mechanisms are connected by a transverse pull rod 160; a pressing bolt hole penetrating through the vertical plate 120 and a pressing bolt 150 screwed in the pressing bolt hole are provided on the vertical plate 120. By the pressing bolt 150 pressing against the shaft flange 610, the fixing mechanism can be stably fixed on the shaft flange 600 based on the circumferential surface fixing and the disk surface fixing methods, avoiding the vertical plate 120 from moving left and right, realizing the left-right direction fixing of the boring machine, and ensuring the boring accuracy.

[0066] That is to say, the fixing mechanism is fixed in the perpendicular directions by the pressing bolt 150, the second positioning adjustment bolt 190, and the first positioning adjustment bolt 140 to maintain a stable fixing state. In order to avoid scratching the workpiece, spherical surfaces can be provided at the ends of the pressing bolt 150, the second positioning adjustment bolt 190, and the first positioning adjustment bolt 140.

[0067] In order to further improve the reliability of the fixing structure, a reinforcing rib plate 170 can be provided between the upper bottom plate 110 and the vertical plate 120 to strengthen its structure, avoid deformation under stress, and ensure the morphological stability of the fixing structure.
