Description
Technical field
The utility model relates to a kind of rig, especially a kind of centre bore special drilling machine that is used for the processing of turbine rotor centre bore.
Background technology
At present in the processing industry of steam turbine spare and accessory parts, the processing of turbine rotor centre bore adopts floor-type milling ﹠ boring machine and turning milling center to process usually, though this traditional processing mode can guarantee machining accuracy, but because floor-type milling ﹠ boring machine and turning milling center are for the comparatively inconvenience of clamping of turbine rotor, and operation is comparatively complicated when looking for location, the center of circle, not only production efficiency is low, when looking for the center of circle, location, do not have slightly and very just can influence crudy, take simultaneously this nervous machine tooling ability again in a large number, become the bottleneck of steam turbine spare and accessory parts processing.Along with the demand in steam turbine market constantly increases, the significantly raising of product sales volume, existing production and processing progress can't satisfy the production demand, so people thirst for a kind of structure special drilling machine simple and direct, easy to use always and solve bottleneck problem in the process of manufacture.
Summary of the invention
The purpose of this utility model is that provide for the deficiency that solves above-mentioned technology a kind of clamps conveniently, the centre bore special drilling machine of accurate positioning.
In order to achieve the above object, the centre bore special drilling machine that the utility model is designed, it mainly comprises base, drilling equipment and clamping device, drilling equipment and clamping device are arranged on the base, described clamping device comprises screw mandrel, two binding nut pieces and guide rail, two binding nut pieces be arranged on the screw mandrel by being threaded and direction of rotation opposite, two binding nut pieces are slidingly connected on the guide rail simultaneously, described screw mandrel and guide rail are arranged on the base, and described drilling equipment is positioned at the side of two binding nut pieces.Wherein said being slidingly connected can be that chute is set on the guide rail, and the binding nut piece is arranged in the chute.
As preferably, described screw mandrel two ends are provided with the adjustment nut.
As preferably, the below of described binding nut piece is provided with linear rolling guide, and described linear rolling guide comprises guide rail and two slide blocks, and slide block can slide on guide rail, described binding nut piece is fixedly installed on the slide block respectively, thereby forms and being slidingly connected of guide rail.Binding nut piece thread rotary orientation one the first from left right side, and the worm drive between the screw mandrel make that two binding nut pieces are approaching simultaneously or leave the purpose that reaches quick clamping and unclamp workpiece fast simultaneously.Adopting linear rolling guide in addition in this mechanism mainly is that nut block and screw mandrel reduce the power that is bent upwards and guarantee that the centralized positioning of binding nut piece is accurate when getting rid of clamping work pieces, strengthens the intensity of screw mandrel simultaneously.Because screw mandrel can produce the power of overturning that makes progress when clamping work pieces, make screw mandrel can produce bending, so being installed, line slideway auxiliary can not only offset the power of overturning that screw mandrel clamps generation below the binding nut piece, the power of overturning about also producing when boring in addition, line slideway auxiliary also can overcome this and overturn power.
As preferably, described drilling equipment is arranged on the base by the liftable structure.Thereby can the bit central of drilling equipment be adjusted to consistent by lifting with the machining center of workpiece.
As preferably, described binding nut piece is a V-type binding nut piece.
The centre bore special drilling machine that the utility model obtains, simple in structure, easy to carry.Rotor need be driven a vehicle usually to lift on floor-type milling ﹠ boring machine and the turning milling center and be processed in the past, and this centre bore special drilling machine only need lie in rotor on the rotor rack, the bit central of drilling equipment is adjusted to consistent with rotor center, direct clamping rotor can be finished and clamp when treating position suitable, reduce the lifting and a lot of auxiliary clamping time of driving, and look for the center of circle, location more accurate, when improving working (machining) efficiency, also improved crudy.
Description of drawings
Fig. 1 is the front view of embodiment 1 centre bore special drilling machine;
Fig. 2 is the side view of embodiment 1 centre bore special drilling machine.
Among the figure: V-type binding nut piece 1, screw mandrel 2, adjustment nut 3, slide block 4, linear rolling guide 5, base 6, drilling equipment 7, guide rail 8.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1
As shown in Figure 1, the described centre bore special drilling machine of present embodiment, it mainly comprises base 6, drilling equipment 7 and clamping device, drilling equipment 7 and clamping device are arranged on the base 6, clamping device comprises screw mandrel 2, two V-type binding nut pieces 1 and guide rail 8, two V-type binding nut pieces 1 be arranged on the screw mandrel 2 by being threaded and direction of rotation opposite, the below of V-type binding nut piece 1 is provided with linear rolling guide 5, linear rolling guide 5 comprises guide rail 8 and slide block 4, V-type binding nut piece 1 is fixedly installed on respectively on the slide block 4, thereby formation is slidingly connected with guide rail, screw mandrel 2 and guide rail 8 are arranged on the base 6, drilling equipment 7 is positioned at the side of two V-type binding nut pieces 1, and screw mandrel 2 two ends are provided with adjusts nut 3.Drilling equipment 7 is the rig of prior art, does not add tired stating at this.
During use, make the right V-type binding nut of the first from left piece 1 to the mobile clamping work pieces in centre by hand rotation screw mandrel 2, screw mandrel 2 reduces the power that is bent upwards when making V-type binding nut piece 1 clamping work pieces, so linear rolling guide 5 is installed on base 6, prevent V-arrangement nut block generation disturbing moment and cause V-arrangement nut block center and the dislocation of drilling equipment 7 alignments of shafts, increase the intensity of screw mandrel 2 simultaneously.The center of workpiece centre and drilling equipment 7 main shafts can by about adjustment nut 3 regulate (adjustment when installing).This clamping device utilizes equidistant left and right sides spiral to drive two slide constant speed movement to the therebetween clamping of workpieces by 1 centering of V-type binding nut piece, when outwards separating, then unclamps workpiece.Rotor need be driven a vehicle usually to lift on floor-type milling ﹠ boring machine and the turning milling center and be processed in the past, and only rotor need be lain on the rotor rack now, utilize the hand propelled lift cart to adjust to the rig center of drilling equipment 7 consistent with rotor center, directly clamp rotor when treating position suitable, because two V-type nut block centers are consistent with the rig center, therefore can process as long as clamp.Can reduce the lifting and a lot of auxiliary clamping time of driving like this.
In order to make drilling equipment 7 can carry out lifting more easily, described drilling equipment 7 is arranged on the base 6 by the liftable structure.The liftable structure can be the wheel and rack structure, also can be screw mandrel 2 and nut structure, can also be sprocket wheel and chain structure, and the liftable structure is a prior art, is not described further at this.
The drilling equipment 7 that present embodiment is described, can adopt magnetic force to bore transformation forms, the magnetic bases 6 that magnetic force is bored remove, directly be connected on the base 6 by bolt, this spline structure was both small and exquisite and reduced the machinery and the electrical design of drilling equipment 7, the magnetic force brill itself has two grades of stepless speed regulations of machinery, can satisfy the requirement of centre bore processing to rotating speed.
