Abstract
The invention discloses a feeding device of a rotary spindle, and relates to the technical field of manufacturing of mechanical machining equipment. According to the feeding device, a motor drives a pin roller lead screw to rotate; a nut arranged on the pin roller lead screw transversely moves on the pin roller lead screw; the nut also drives a bracket connected with the nut to move, and therefore the bracket drives a boring shaft connected with the bracket to perform linear motion. According to the feeding device, the problems that a traditional feeding system is low in rigidity, large in transmission error and low in transmission efficiency are solved.
Description
Technical field
The present invention 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 take as the leading factor in the mode that servomotor adds mechanical drive train, there is many problems in this traditional feed system, such as, rigidity is low, driving error is large, transmission efficiency is low.
Summary of the invention
The object of this invention is to provide a kind of rotary main shaft feed arrangement, 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 solve the problem, the technical solution used in the present invention is: this rotary main shaft feed arrangement, comprise outer container, roller screw mandrel is provided with in described outer container, boring axle, for the backstay of locating, with brake motor and be provided with the bracket of upper hole, mesopore and lower opening, be provided with through hole between the outer wall in hole and hole on described, the inwall of this through hole is provided with screw thread; Described motor is connected by shaft coupling one end with described roller screw mandrel, and described roller screw mandrel is provided with connected nut, and the through described upper hole of this nut is fixedly connected with described bracket; The other end of described roller screw mandrel is connected with support; The through described mesopore in one end of described boring axle 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 opening and is connected with supporting member, and its other end is connected with holder.
In technique scheme, more specifically scheme can also be: one end end face of described nut is provided with several interior threaded hole.
Further: the end face of the upper hole of described bracket and same one end of lower opening is provided with several interior threaded hole.
Further: described backstay (3) is linear bearing.
Owing to have employed technique scheme, compared with prior art, the beneficial effect had is in the present invention: directly drive roller screw mandrel owing to adopting motor by shaft coupling, the mechanical drive trains such as gear are deducted, thus simplify drive mechanism, improve transmission efficiency, reduce driving error.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment:
Rotary main shaft feed arrangement shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, roller screw mandrel 1 is provided with in outer container, boring axle 2, for the backstay 3 of locating, with motor 4 and the bracket 6 being provided with upper hole 6-1, mesopore 6-2 and lower opening 6-3 of brake, between the outer wall and hole of upper hole 6-1, be provided with through hole, the inwall of this through hole is provided with screw thread; The end face of same one end of the upper hole 6-1 and lower opening 6-3 of bracket 6 is provided with several interior threaded hole; In the present embodiment, the end face of upper hole 6-1 has 6 holes, and lower opening 6-3 has 4 holes; The end face of nut 5 one end is provided with threaded hole in 6, these 6 holes are corresponding with 6 holes of upper hole 6-1 end face.Motor 4 is connected by shaft coupling one end with roller screw mandrel 1, and the other end of roller screw mandrel 1 is connected with support 7; Roller screw mandrel 1 is provided with nut 5, this roller screw mandrel 1 is threaded with nut 5, the through upper hole 6-1 of nut 5, nut 5 has the end face of screwed hole to have the end face of screwed hole to abut with upper hole 6-1, with bolt, they is fixedly connected with, simultaneously, by female through hole between the outer wall of upper hole 6-1 and hole, with bolt, nut 5 is fixedly connected with bracket 6, like this, nut 5 is more firm with the connection of bracket 6.The through mesopore 6-2 in one end of boring axle 2 is also 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 opening 6-3 and be connected with supporting member 8 with a flange, one end face of flange abuts with an end face of lower opening 6-3 and is screwed, thus is locked by backstay 3, and backstay 3 other end is connected with holder 9.
Operationally, motor 4 drives roller screw mandrel 1 to rotate by shaft coupling, and nut 5 is transverse shifting on roller screw mandrel 1, because bracket 6 and nut 5 are be fixedly connected with boring axle 2, so nut 5 drives bracket 6 to move, bracket 6 also just drive boring axle 2 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 opening 6-3 and is connected with supporting member 8, makes bracket 6 can only follow nut 5 and laterally moves along backstay 3 axis direction, thus it is more steady that straight-line feed is moved.In the present embodiment, backstay 3 is linear bearings, slip can be become rolling with linear bearing, can reach the object reduced friction like this.
