Abstract
The invention relates to a tool rest mechanism of a large-scale vertical lathe. A supporting seat is fixed on a top end face of a carriage sliding table; an upper bearing seat assembly is arranged on the supporting seat; a lower bearing seat assembly is arranged on the carriage sliding table; a ball screw rotates between the upper bearing seat assembly and the lower bearing seat assembly; a screw nut is connected to the ball screw through threads; a cover plate is fixedly arranged on one side of the carriage sliding table; an adjustment cushion block is arranged between the cover plate and the carriage sliding table; the section of a ram is in a polygonal shape; each top angle in the polygonal section is an obtuse angle; the polygonal section has at least two parallel edges; the adjustment cushion block is positioned on the side wall of the ram which corresponds to the two parallel edges in the section; a lathe tool seat is fixed at the bottom of the ram; a smart seat is fixed at the top of the ram; and the ram is fixedly connected with the screw nut into a whole. The tool rest mechanism of the large-scale vertical lathe has the advantages of simple structure, convenience for assembly, low processing cost, convenience for adjustment and the like.
Description
Technical field
The present invention relates to a kind of parts of the upper and lower motion of lathe tool of the large-scale vertical lathe that is used for large diameter ring, flange or forging processing, especially a kind of large-scale vertical lathe cutter frame mechanism.
Background technology
In existing technology, what the knife rest of large-scale vertical lathe generally adopted is square ram, and the clearance control between ram and the slide unit is to utilize wedge to control, and processing cost is high, the structure relative complex, and matching requirements are high.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, provide a kind of simple in structure, easy to assembly, processing cost is low, the large-scale vertical lathe cutter frame mechanism being convenient to adjust.
According to technical scheme provided by the invention; Said large-scale vertical lathe cutter frame mechanism; Be included in hard-wired bearing on the top end face of planker slide unit, the top chock assembly is installed on bearing, the step assembly is installed on the planker slide unit; Between top chock assembly and step assembly, be rotatablely equipped with ball screw, on ball screw, be bolted with the feed screw nut; Side at the planker slide unit is installed with cover plate, between cover plate and planker slide unit, is provided with the adjustment parallels; Described cover plate and planker slide unit surround the slide opening of vertical layout; The ram that in slide opening, has been slidingly installed, the section configuration of said ram is a polygon, each drift angle is the obtuse angle in the said polygonal section; And have two parallel edges in the polygonal section at least; Said adjustment parallels is arranged in the sidewall of the corresponding ram of section two parallel edges, and the bottom of ram is installed with the lathe tool seat, and the epimere of ram stretches in the bearing; The top ends of ram is installed with the spirit seat of living, and the spirit seat of living is fixedly connected one with described feed screw nut.
The section configuration of said ram is for having regular hexagon or octagon.
That the present invention has is simple in structure, easy to assembly, processing cost is low be convenient to advantage such as adjustment.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention.
Fig. 2 is A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure, the present invention mainly is made up of parts such as bearing 1, the spirit seat 2 of living, ram 3, cover plate 4, adjustment parallels 5, top chock assembly 6, ball-screw 7, step assembly 8, planker slide unit 9, lathe tool seat 10, feed screw nut 11 and slide openings 12.
This a kind of large-scale vertical lathe cutter frame mechanism; Be included in hard-wired bearing 1 on the top end face of planker slide unit 9; Top chock assembly 6 is installed on bearing 1; Step assembly 8 is installed on planker slide unit 9, between top chock assembly 6 and step assembly 8, is rotatablely equipped with ball screw 7, on ball screw 7, be bolted with feed screw nut 11; Side at planker slide unit 9 is installed with cover plate 4, between cover plate 4 and planker slide unit 9, is provided with adjustment parallels 5; Described cover plate 4 and planker slide unit 9 surround the slide opening 12 of vertical layout; The ram 3 that in slide opening 12, has been slidingly installed, the section configuration of said ram 3 is a polygon, each drift angle is the obtuse angle in the said polygonal section; And have two parallel edges in the polygonal section at least; Said adjustment parallels 5 is arranged in the sidewall of the corresponding ram 3 of section two parallel edges, and the bottom of ram 3 is installed with lathe tool seat 10, and the epimere of ram 3 stretches in the bearing 1; The top ends of ram 3 is installed with the spirit seat 2 of living, and the spirit seat 2 of living is fixedly connected one with described feed screw nut 11.
The section configuration of said ram 3 is for having regular hexagon or octagon.
Bearing 1 is connected with planker slide unit 9 usefulness bolts among the present invention, and top chock assembly 6 usefulness bolts are connected with bearing 1, and step assembly 8 usefulness bolts are connected with planker slide unit 9; Ball-screw 7 is installed between top chock assembly 6 and the step assembly 8, and the spirit seat 2 of living is connected with ram 3 usefulness bolts, and parallels 5 is adjusted in installation between cover plate 4 and the planker slide unit 9; Connect with bolt later on, according to the gap that requires of ram 3 and planker slide unit 9, as long as the thickness of reconditioning adjustment parallels 5 can reach requirement; Lathe tool seat 10 is installed in the bottom of ram 3; Through the rotation of ball screw 7, drive moving up and down of feed screw nut 11, drive the spirit seat 2 of living thus and move up and down; The spirit seat 2 of living drives ram 3 and moves up and down, and realizes the upper and lower motion of lathe tool seat 10 through ram 3.
