Description
Technical field
The present invention relates to a kind of machinery, particularly relate to a kind of device that is suitable for little interior volume boring, tapping processing.
Background technology
In Drilling operation or the tapping of carrying out little interior volume, add man-hour, difficulty is larger.In most cases adopt 90 degree angle air drill processing, the perpendicularity in hole cannot guarantee, affect product processing quality.Patent of invention " a kind of processing unit (plant) of small space internal holes " (application number: 200920082932.0), improve, utilize magnetic force dial plate seat and adjust double-screw bolt to position, though the perpendicularity in the hole after processing increases, still utilize this device to add man-hour, need left hand to hold guider handle, the right hand is held 90 degree elbow gas handles, and labour intensity is large, and both hands are while using force unbalance, the perpendicularity in hole is affected, and cannot guarantee the quality of machining hole.Patent of invention " 90 ° of boring drill chucks " (application number: 201120058930.4), the hand held electric drill that carries out power commutation by a secondary bevel gear, can realize axis and turn to, but cannot adapt to the processing of the boring of little space inwall, tapping.In addition, above-mentioned two patents are all to utilize bimanualness, and two hands firmly need to keep evenly, and man's activity is large, and labour intensity is large, and machining accuracy is difficult to guarantee, is not more suitable for batch production processing.
Summary of the invention
The object of this invention is to provide the processing unit (plant) of a kind of little interior volume drilling, tapping, be suitable for the internal drilling of little space, tapping processing, machining accuracy is high, constant product quality, and labour intensity is low, adapts to produce in enormous quantities processing.In addition, also has following extreme processing environment: when little space inwall processing obstructed (blind) hole, existing technique is generally to adopt from the outside to get through, and then mends lastblock from the outside, by real outer end of hole envelope; If the original wall thickness of part is just very little, very tight again to hole depth requirement, prior art is obviously infeasible, then for the high product of environmental requirement, so just less qualified to do it.This device has just solved this problem, can be installed on lathe and bore blind hole from inside workpiece, then carry out tapping processing, and this has just solved above all difficulties, and machining accuracy is the same with lathe.
For solving the problems of the technologies described above, technical solution of the present invention is: comprise gear-box and axle sleeve for being connected described drilling, threading apparatus collar bush; Described gear-box has power shaft and output shaft, and power shaft is identical with output shaft direction of rotation and be parallel to each other, described power shaft from the end face of described gear-box stretch out and with the dead in line of described axle sleeve; Described output shaft stretches out from the bottom surface of described gear-box.
In described gear-box, between described power shaft and output shaft, by the intermeshing travelling gear of odd number, be connected.
Also comprise connecting plate, described axle sleeve is fixedly connected with gear-box by connecting plate.
Described axle sleeve and connecting plate are monoblock cast structure.
The present invention utilizes gear-box to realize the transverse translation of drill bit, and drill bit under, state in the same way parallel with axis, can be extend in small space keeping, and the radial blind holes of small space inwall is processed.With respect to this kind of extreme process environments, the rigidity of gear-box of the present invention reaches the requirement of machining accuracy completely, that is to say gear-box unlikely distortion when carrying drilling axial resistance.Exquisite composition of the present invention, has broken the traditional form processing in this area, has solved in prior art unsolved technical barrier always.
The advantage of apparatus of the present invention is: 1, gear-box is connected as one by connecting plate and axle sleeve, compact conformation, and integral rigidity is good; 2, the shank of cutter is an entirety as gearbox output shaft; 3, the axis of axle sleeve and the dead in line of power shaft, axle sleeve can be sleeved on the main shaft outer shaft of the equipment such as drilling machine, machining center like this, the power shaft of gear-box can with the main shaft joint transmissions such as machining center; 4, utilize gearbox drive, realize output shaft parallel offset main shaft certain distance, can stretch into parts small space inside, realization is holed in little space, tapping processing; 5, power shaft is identical with output shaft direction of rotation, and cutter advances or exits clearly, and manipulation is convenient; 6, utilize the transmission of gear bar case, rigidity is large, and machining accuracy height can reach the precision equal with lathe, and constant product quality can adapt to produce in enormous quantities processing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention,
Fig. 2 is the schematic perspective view one of application state of the present invention,
Fig. 3 is the schematic perspective view two of application state of the present invention;
In figure: 1-gear-box, 2-axle sleeve, 3-keyset, 4-cutter, 5-lock-screw, 11-gearbox input shaft, 12-gearbox output shaft, 13-travelling gear, 6-shaft coupling, 7-machine tool chuck, 8-main shaft.
The specific embodiment
As Figure 1-3, the little Space processing device of the present invention, comprises gear-box 1 and axle sleeve 2 for being connected described drilling, threading apparatus machine tool chuck 7; Described gear-box 1 has power shaft 11 and output shaft 12, and power shaft 11 is identical with output shaft 12 direction of rotation and be parallel to each other, described power shaft 11 from the end face of described gear-box 1 stretch out and with the dead in line of described axle sleeve 2; Described output shaft 12 stretches out from the bottom surface of described gear-box 1.Cutter 4 connects with output shaft 12.
Between the interior described power shaft 11 of described gear-box 1 and output shaft 12, by the intermeshing travelling gear 13 of odd number, be connected.Consistent with the choice direction of output shaft 12 to guarantee power shaft 11, when selecting gear, can select as required corresponding size, gearratio, to be applicable to the requirement of power shaft 11 and output shaft 12 deviation distances.Gear is many, size is large, and deviation distance is just large, and the distance that can " extend transversely into " is just far away.Otherwise quite different.
Also comprise connecting plate 3, described axle sleeve 2 is fixedly connected with gear-box 1 by connecting plate 3.
Described axle sleeve 2 is overall structure with connecting plate 3.For realization and the coordination of machining center, connecting plate 3 can be made into tubular.
For ease of with being connected of the drillings such as machining center, upright drill, threading apparatus main shaft core, shaft coupling 6 can also be set on power shaft top.
Because the equipment such as drilling machine, machining center have machine tool chuck 7 and main shaft 8, axle sleeve 2 utilizes the lock-screw 5 (note: machine tool chief axis 8 is only to move up and down that is connected with machine tool chief axis 8, machine tool chuck 7 is to rotatablely move, and moves up and down with main shaft 8), and then realize axial feed; Machine tool chuck 7, in company with main shaft 8 axial feeds, is also rotated, and then band driven input shaft 11 rotates.
The present invention utilizes the transmission of gear bar case, realize output shaft parallel offset main shaft, rigidity is large, and compact conformation can be used in conjunction with equipment such as drilling machine, machining centers, be suitable in little space (as the work piece of likeness in form lid in the leftmost side in Fig. 1, processing blind hole tapping on inner circle sidewall) boring, tapping processing, machining accuracy is high, constant product quality, labour intensity is low, adapts to produce in enormous quantities processing.Can be in drilling machine, machining center, even hand-held drilling machine coordination is used, and realizes the drilling processing to extreme occasion (narrow and small state space madial wall blind hole).
