For solving the problems of the technologies described above, technical scheme of the present invention is: the special profile planer-type broaching of multitool lathe, comprise base, and also comprise workbench, said workbench is arranged on the said base, drives the vertical linear reciprocating motion along said base by power set; Gantry type frame, said gantry type frame are arranged on the said base, and said gantry type frame comprises two columns and the back timber that is arranged on said column top; Crossbeam, said crossbeam are installed on said two columns and are positioned at the below of said back timber, and the bottom of said crossbeam is equipped with a plurality of tool rests, on each said tool rest broaching tool is installed, and the broaching tool on said a plurality of tool rests is specification of the same race or different size.
As preferably, be separately installed with ball-screw on said two columns by driven by servomotor, said crossbeam is connected through the leading screw pair of nut with said ball-screw.
As preferably, said broaching tool is the combined type broaching tool.
As preferably, said power set comprise hydraulic cylinder.
Owing to adopted technique scheme, the invention has the beneficial effects as follows: because the base of the special profile planer-type broaching of multitool of the present invention lathe is provided with gantry type frame, said gantry type frame comprises two columns and the back timber that is arranged on the column top; The crossbeam that is positioned at the back timber below also is installed on said two columns, and the bottom of said crossbeam is equipped with a plurality of tool rests, on each said tool rest broaching tool is installed, and the broaching tool on said a plurality of tool rests is specification of the same race or different size.The special profile planer-type broaching of this multitool lathe adds man-hour in that some workpiece of unified specification are broached; A broaching tool is installed on each tool rest, and the specification of all broaching tools is identical, fixing some workpiece to be processed on workbench; The arrangement mode of workpiece is: the position corresponding to each broaching tool is provided with a row workpiece; Like this can be on workbench fixing multiple row workpiece, each row comprises a plurality of workpiece, adjusts the position of crossbeam; When power set drove the workbench moving linearly through gantry type frame, many broaching tools that are provided with on a plurality of tool rests were realized the disposable broaching processing to the multiple row workpiece.Add man-hour in that some workpiece of different size are broached, only need the broaching tool corresponding to workpiece to be processed is installed on each tool rest, can carry out disposable broaching processing some workpiece of different size.With once can only compare the broach broaching machine of prior art of processing of a workpiece, the special profile planer-type broaching of multitool of the present invention lathe can greatly improve broaching production efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is that sketch map is looked on the left side of Fig. 1;
Among the figure: the 1-base; The 2-workbench; The 3-workpiece; The 4-tool rest; The 5-crossbeam; The 6-column; 7-tool rest fixed head; The 8-broaching tool; The 9-back timber; The 10-servomotor; The 11-ball-screw; The 12-hydraulic cylinder.
The specific embodiment
Shown in Fig. 1 and Fig. 2 were common, the special profile planer-type broaching of multitool lathe comprised base 1; Workbench 2, said workbench 2 are arranged on the said base 1, drive the vertical linear reciprocating motion along said base 1 by power set, and power set wherein adopt hydraulic cylinder 12, in order to drive workbench 2 and to control its stroke; Gantry type frame, said gantry type frame are arranged on the said base 1, and said gantry type frame comprises two columns 6 and the back timber 9 that is arranged on said column 6 tops; Also be provided with crossbeam 5 on the said gantry type frame; Said crossbeam 5 is installed on said two columns 6 and is positioned at the below of said back timber 9; The bottom of said crossbeam 5 is provided with tool rest fixed head 7; A plurality of tool rests 4 are installed on this tool rest fixed head 7, through bolt broaching tool 8 are installed on each said tool rest 4, the broaching tool 8 on said a plurality of tool rests 4 is specification of the same race or different size.
Conventional broaching machine adopts broaching tool motion, the fixing mode of workpiece, and its stroke is mostly at 2000mm, and the broaching machine stroke of indivedual models reaches 3000 mm.Broaching machine adopted gantry type frame structure of the present invention, and the broaching layout of broaching tool fixation workpiece motion, the broaching stroke is long, and stroke is at least 3000 mm, according to user's needs 6000 mm, 12000 mm strokes can be provided, and maximum can reach 25000 mm strokes.Because of workbench has long length; Bigger area; The more conventional broaching machine of workpiece quantity that can install on the workbench can improve tens times, can accomplish the broaching of a plurality of (special profiles such as plane or arcwall face) simultaneously, and gross efficiency improves than conventional broaching machine can reach hundreds of times.
The workbench 2 of this broaching lathe is low apart from ground location, and area is big, can carry out clamping or dismounting, high efficiency to workpiece 3 simultaneously by many people.
In the present embodiment, be separately installed with the ball-screw 11 that is driven by servomotor 10 on said two columns 6, said crossbeam 5 is connected through the leading screw pair of nut with said ball-screw 11.The height of the said crossbeam 5 of scalable when servomotor 10 drives ball-screw 11 rotations is to adapt to the needs of broaching processing.
In the present embodiment, said broaching tool 8 adopts the combined type broaching tools, and promptly every broaching tool 8 combines by several sections.Broaching tool is generally made with valuable cutter materials such as carbide alloy, costs an arm and a leg.After the cutter tooth of a certain section broaching tool or indivedual broaching tool wearing and tearing or breakage, only need carry out local replacing, can reduce the manufacturing and the reconditioning cost of broaching tool like this, the risk of having avoided whole cutter to scrap has prolonged service life of whole broaching tool, has saved valuable cutter material.The combined type broaching tool is easy to adjust, and applicability is wide.
In the present embodiment, said power set comprise hydraulic cylinder 12, drive workbench 2 is also controlled workbench 2 through the control system stroke by hydraulic cylinder 12.Adopt Driven by Hydraulic Cylinder, stable drive can be carried out stepless speed regulation as required, and is easy to adjust, quick, reliability is high.
Operation principle: add man-hour when broaching to some workpiece 3 of unified specification; A broaching tool 8 is installed on each tool rest 4, and the specification of all broaching tools 8 is identical, fixing some workpiece to be processed 3 on workbench 2; The arrangement mode of workpiece 3 is: the position corresponding to each broaching tool 8 is provided with a row workpiece; Like this can be on workbench 2 fixing multiple row workpiece, each row comprises a plurality of workpiece, adjusts the position of crossbeam 5; When hydraulic cylinder 12 drove workbench 2 moving linearlies through gantry type frame, many broaching tools 8 that are provided with on a plurality of tool rests 4 were realized the disposable broaching processing to the multiple row workpiece.Add man-hour when broaching, only need the broaching tool 8 corresponding to workpiece to be processed is installed on each tool rest 4, can carry out disposable broaching processing some workpiece of different size to some workpiece 3 of different size.Production practices prove: with once can only compare the broach broaching machine of prior art of processing of a workpiece, the special profile planer-type broaching of multitool of the present invention lathe can greatly improve broaching production efficiency.
The above is giving an example of best mode for carrying out the invention, and the part of wherein not addressing in detail is those of ordinary skills' common practise.Protection scope of the present invention is as the criterion with the content of claim, and any equivalent transformation that carries out based on teachings of the present invention is also within protection scope of the present invention.
