Abstract
The utility model discloses a feed device of a rotating spindle, and relates to the technical field of machining equipment manufacturing. A motor drives a roller screw to rotate, and a nut arranged on the roller screw moves horizontally on the roller screw and drives a bracket connected with the nut to move, so that the bracket drives a boring shaft connected with the bracket to move linearly. According to the feed device of the rotating spindle, the problems that a conventional feed system is low in rigidity, large in transmission error and low in transmission efficiency can be solved.
Description
Technical field
The utility model relates to machining equipment manufacturing technology field, especially a kind of rotary main shaft feed arrangement for large-size numerical control machine.
Background technology
The feeding of current Digit Control Machine Tool parts moving linearly, still takes as the leading factor in the mode that servomotor adds mechanical drive train, and this traditional feed system exists many problems, such as, rigidity is low, driving error is large, transmission efficiency is low etc.
Summary of the invention
The purpose of this utility model is to provide a kind of rotary main shaft feed arrangement, and it can solve the problem that traditional Rigidity of Feed System is low, driving error is large and transmission efficiency is low.
In order to address the above problem, the technical solution adopted in the utility model is: this rotary main shaft feed arrangement, comprise outer container, in described outer container, be provided with roller screw mandrel, boring axle, for the backstay of locating, with motor and the bracket that is provided with upper hole, mesopore and lower hole of brake, between the outer wall in hole and hole, be provided with through hole on described, the inwall of this through hole is provided with screw thread; Described motor is connected with one end of described roller screw mandrel by shaft coupling, and described roller screw mandrel is provided with connected nut, and this nut connects described upper hole and is fixedly connected with described bracket; The other end of described roller screw mandrel is connected with support; One end of described boring axle connects described mesopore and is connected with described bracket, and the other end of this boring axle runs through described outer container tank wall; One end of described backstay is run through described lower hole and is connected with supporting member, and its other end is connected with holder.
In technique scheme, more specifically scheme can also be: on one end end face of described nut, be provided with several interior threaded holes.
Further: on the end face of the same one end in the He Xia hole, upper hole of described bracket, be provided with several interior threaded holes.
Further: described backstay (3) is linear bearing.
Owing to having adopted technique scheme, compared with prior art, the beneficial effect having is the utility model: owing to adopting motor directly to drive roller screw mandrel by shaft coupling, the mechanical drive trains such as gear have been deducted, thereby simplified drive mechanism, improved transmission efficiency, reduced driving error.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Embodiment:
Rotary main shaft feed arrangement shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, in outer container, be provided with roller screw mandrel 1, boring axle 2, for the backstay 3 of locating, motor 4 and the bracket 6 that is provided with upper hole 6-1, mesopore 6-2 and lower hole 6-3 with brake, between the outer wall of upper hole 6-1 and hole, be provided with through hole, the inwall of this through hole is provided with screw thread; On the end face of same one end of the upper hole 6-1He Xia hole 6-3 of bracket 6, be provided with several interior threaded holes; In the present embodiment, the end face of upper hole 6-1 has 6 holes, and lower hole 6-3 has 4 holes; On the end face of nut 5 one end, be provided with threaded hole in 6,6 holes of this Yu Shang hole, 6 holes 6-1 end face are corresponding.Motor 4 is connected with one end of roller screw mandrel 1 by shaft coupling, and the other end of roller screw mandrel 1 is connected with support 7; On roller screw mandrel 1, be provided with nut 5, this roller screw mandrel 1 is threaded with nut 5, nut 5 connects upper hole 6-1, nut 5 has the end face of screwed hole and the end face butt that upper hole 6-1 has screwed hole, with bolt, they is fixedly connected with, simultaneously, female through hole between outer wall by upper hole 6-1 and hole, with bolt, nut 5 is fixedly connected with bracket 6, like this, nut 5 is more firm with being connected of bracket 6.One end of boring axle 2 connects mesopore 6-2 and is connected with bracket 6 with screw, and the other end of boring axle 2 runs through the equipment connection outside outer container tank wall and case; In backstay 3(the present embodiment, backstay 3 is linear bearing) one end run through lower hole 6-3 and be connected with supporting member 8 with a flange, an end face butt of one end face of flange and lower hole 6-3 is also screwed, thereby by backstay 3 lockings, backstay 3 other ends are connected with holder 9.
When work, motor 4 drives roller screw mandrel 1 to rotate by shaft coupling, and nut 5 is transverse shifting on roller screw mandrel 1, and because bracket 6 is to be fixedly connected with nut 5 with boring axle 2, so nut 5 drives bracket 6 to move, bracket 6 also just drives boring axle 2 to do rectilinear motion; In order to make the feed motion of lathe more steady, so be provided with backstay 3, one end of backstay 3 is run through lower hole 6-3 and is connected with supporting member 8, makes bracket 6 can only follow nut 5 and laterally moves along backstay 3 axis directions, thereby make straight-line feed motion more steady.In the present embodiment, backstay 3 is linear bearings, with linear bearing, slip can be become to rolling, can reach the object reducing friction like this.
