Abstract

The utility model provides the technical proposal of a digital control deep hole boring machine in a digital control system. The scheme is characterized in that on the basis of an existing deep-hole boring machine, a component clamping trailing bar is provided with a digital control device, and the digital control device is used to control a Z-direction feeding box and an X-direction feeding box. A controlled servo motor is used to drive a couple of gears meshed with the rack bar of the machine tool through a planetary gear train and a gear group to compose the Z-direction feeding box which is used to control the axial direction position of the diameter changing boring cutter of a controlling drilling rod in the hole. The controlled servo motor is used to drive a ball screw pair through a serrated belt to compose the X-direction feeding box which is used to control the diameter changing bar in the boring bar; the digital control deep hole boring machine can be used to process deep holes with special shapes such as the conic shape, the bottle neck shape, the curved face, the deep part incising groove shape, etc.

Description

CNC deep-hole drilling ﹠ boring machine

It is machining equipment that the utility model relates to, and especially adopts the digital control CNC deep-hole drilling ﹠ boring machine that can process special moldeed depth hole.

In recent years, all propose to process the requirement of special-shaped deep holes such as taper shape, bottleneck in industries such as Aeronautics and Astronautics, plastics machinery, light industry and machinery.Yet domestic present employed deep hole drilling and boring machine can only processing column shape deep hole, still can't process such as special-shaped deep holes such as bottleneck, curved surface shaped.Even if processing is the conical deep hole of rule relatively, also need the time of the high operator of technical merit and tens of days to finish, process extremely difficult.

The purpose of this utility model, can't process the problem in special-shaped hole exactly at deep hole drilling and boring machine of the prior art, and a kind of employing digital control technology is provided, can process taper shape, bottleneck, curved surface shaped, deep and cut the technical scheme that boring machine is bored in the numerical control of special-shaped deep holes such as groove.

For finishing above-mentioned task, this programme has adopted following technical characterstic.By lathe bed with and on headstock, tight part planker, the feed box of awarding oily device, drilling rod, drill rod box and dragging drill rod box, in addition, also having at headstock and awarding between the oily device has centre frame, is awarding on the deep hole drilling and boring machine basis of being made up of the support of supports drill rods between oily device and the drill rod box.Adopt again on tight part planker and install numerical control device additional, and the described feed box that drags drill rod box, then be to drive the planet circular system that constitutes by gear ring z3, planetary gear z2, gear z4 with gear z1 by the servomotor that is subjected to numerical control device control to drive two coaxial gear z5 by transition gear, z5 meshing gear z6, the coaxial connection gear of z6 z7, two gear z7 then are meshed the Z that constitutes to feed box with tooth bar on the lathe bed.Drilling rod main shaft in described drilling rod and the drill rod box all is cover shape bars of hollow, and the reducing bar is housed in its cavity, one end of this reducing bar is regulated mandrel with the reducing of reducing boring cutter and is connected, and the X of the other end and drill rod box side has connected and composed the CNC deep-hole drilling ﹠ boring machine of this programme to feed box.

This programme is owing to adopted numerical control device, and have by the Z of its control to feed box and X to feed box, so can control the axial location of reducing boring cutter in the hole that is contained on the drilling rod and the position of controlling reducing adjusting mandrel in the reducing boring cutter by numerical control system, reducing amount with control reducing boring cutter, interpolation principle by numerical control system realizes the diaxon continuous control again, can reach the various special-shaped deep hole purposes of processing, and the high-tech operator does not save process time again.As seen the utility model has replenished the defective that prior art can not be processed the special-shaped deep hole, and its effect is significant.

Below by a specific embodiment, and, this programme is described in detail in conjunction with its accompanying drawing.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 be among Fig. 1 embodiment Z to the transmission schematic diagram of feed box;

Fig. 3 be among Fig. 1 embodiment drill rod box and X to the transmission schematic diagram of feed box.

CNC deep-hole drilling ﹠ boring machine be by lathe bed 1 with and on headstock 2, tight part planker 5, award oily device 4, drilling rod 7, drill rod box 9 and drag the feed box of drill rod box 9, in addition, also have at headstock 2 and award centre frame 3 between the oily device 4, on the basis of awarding the existing deep hole drilling and boring machine of forming by the support 6 of supports drill rods 7 between oily device 4 and the drill rod box 9, on tight part planker 5, add numerical control device 14 again.The described feed box that drags drill rod box 9 then is to drive the planet circular system that is made of gear ring z3, planetary gear z2, gear z4 by the servomotor 16 usefulness gear z1 that are subjected to numerical control device 14 controls to drive two coaxial gear z5 by transition gear, z5 meshing gear z6, the coaxial connection gear of z6 z7, two gear z7 then are meshed the Z that constitutes to feed box 12 with tooth bar 13 on the lathe bed 1.The drilling rod main shaft 18 that is used for jointed rod 7 in described drilling rod 7 and the drill rod box 9 all is cover shape bars of hollow, and reducing bar 8 is housed in its cavity, one end of this reducing bar 8 is regulated mandrel with the reducing of reducing boring cutter and is connected, and the other end is connected to feed box 10 with the X of drill rod box 9 sides.Above-mentioned X is to drive ball-screw G by the servomotor 17 that is subjected to numerical control device 14 controls by synchronous cog belt to feed box 10, and the nut of ball-screw G then connects and composes with reducing bar 8.And described drill rod box 9 is to connect two groups of reduction gearing by motor 15 by electromagnetic clutch B to remove driven wheel z8, the gear z8 formation that is meshed with gear z9 on being fixed on drilling rod main shaft 18.The numerical control device 14 that is adopted in the present embodiment is KERNEL800T type twin shaft numerical control systems.And servomotor 16 employings is FB25B molded breadth speed-regulated DC motor.What servomotor 17 adopted is FB11 molded breadth speed-regulated DC motor.
