Abstract

The utility model discloses a dovetail forming milling cutter, comprising a face milling cutter 101, an angle cutting tool 105, a dovetail milling cutter 106, and a gouging milling cutter 107 which are sequentially combined. A positioning core shaft is used to integrally position, with a joint element fixing by screws, at the time of combining, and a combination spacers 102 are arranged among the milling cutters. The utility model makes the processing of a dovetail slot and a guide rail singly cut and formed, having the advantages of labor saving and low cost. When one of blades is abrased, the abrased blade can be conditionally replaced. The dovetail forming milling cutter is suitable for processing lathe bed dovetail, the dovetail of a guide rail revolving tray, a guide rail, a lifting platform dovetail, a guide rail, a worktable dovetail, a guide rail, a saddle dovetail slide bearing, etc.

Description

Milling cutter for dovetail grooves forming

The utility model is a kind of combined type dovetail profile milling cutter, is applicable to machining dovetail groove and dovetail guide.

The dovetail groove on the plant equipment and the processing of dovetail guide, because machined surface is many, and machined surface precision, fineness require highly, generally adopts various cutter sequentially a face, a face ground machining, operation is many, time-consuming taking a lot of work, speed is slow, the cost height.

Task of the present utility model is to propose a kind of dovetail profile milling cutter that can finish processing tasks to dovetail groove, guide rail in a procedure simultaneously to each machined surface.

The technical solution of the utility model is the processing request according to dovetail groove, guide rail, with the milling cutter of each face of processing: face cutter, side angle milling cutter, angle cutting tool, dovetail cutter, cut slotting cutter, by connector and shim pack synthesis type.

Because technical scheme of the present invention, the milling cutter combination forming with each face of processing dovetail groove can make the processing of dovetail groove, guide rail finish in a procedure, reduces operation, has saved the man-hour and the energy, reduces cost, and has finished the invention task.

Describe the utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is the structure chart of the utility model dovetail profile milling cutter

Fig. 2 is the structure chart of guide rail

Fig. 3 is the structure chart of dovetail groove 1

Fig. 4 is revolution oat tail groove structure figure

Combination forming milling cutter (see figure 1) of the present utility model is face cutter (101), angle cutting tool (105), and dovetail cutter (106), it is superimposed in regular turn to cut slotting cutter (107), and superimposed back is by the positioning core axle location, and the back, location is fixed by the connector screw.Face cutter (101) is the upper surface (21) that is used for milling guide rail (Fig. 2), dovetail groove (Fig. 3) and revolution dovetail (Fig. 4).Angle cutting tool (104) be specifically designed to milling revolution dovetail groove concave plane (25) (Fig. 4).This face need not processed on guide rail.Angle cutting tool (105) is the chamfering (26) that is used for milling dovetail groove, guide rail.Cutting slotting cutter is to be used for going out to consider to be worth doing escape (23) and going up baseplane (24) of milling dovetail groove, guide rail.Dovetail cutter (106) is the inclined-plane (22) that is used for milling dovetail groove and guide rail.Each milling cutter is made up of cutterhead and blade.Blade can press-fit and is fixed on the cutterhead with the back pressure type, and blade can be fitted on the cutterhead with preceding pressure type, also can be fixed on the cutterhead with welding procedure.The blade milling cutter different with the combination of cutterhead can be different.Face cutter (101) can adopt preceding pressure type, also can adopt the back pressure type, promptly with briquetting blade is fixed on the cutterhead, and blade can be before or after briquetting.Cut slotting cutter (107) and can adopt welded type, be about to cutter hub and directly be welded on the cutterhead.

For making each milling cutter can closely connected each other and location in when combination, design has bonding pad (102) (Fig. 1).Needs when the shape of bonding pad is made up by each milling cutter decide.Bonding pad is positioning action originally.Fixing of each milling cutter relative position by positioning core axle (109) positioning and fixing, fixedly connected by connector behind the location.This connector is screw (110).

Combining structure decides according to processing work, combining structure shown in Figure 1 is suitable for processing revolution dovetail groove (Fig. 4), use the processing work that it can finish dovetail plane, inclined-plane, chamfering, go out to consider to be worth doing escape in one in-process, make the disposal molding that is processed into of dovetail groove.But when processing general dovetail groove and guide rail (Fig. 2,3), because concave plane (25) need not process, so will unload side angle milling cutter (104) and side angle milling cutter lid (103) in the combining structure (Fig. 1), because side angle milling cutter (104) is exclusively used in milling plane (25) (Fig. 4).As long as unload screw (108), promptly detachable downside angular cutter (104) and side angle milling cutter lid (103).

The quantity of the blade on the cutterhead of each milling cutter can be many, is distributed on the cutterhead by certain circumference angle.

(Fig. 3) processing is lateralized when using the utility model dovetail profile milling cutter processing dovetail groove, can process a side earlier, processes opposite side then.The processing guide rail then can be processed in two sides with two milling cutters when (Fig. 2) simultaneously, if only use singly during the dovetail profile milling cutter, then also can only divide two sides to process certainly.

Use the utility model dovetail profile milling cutter and can process lathe bed dovetail, guide rail, rotating disk dovetail (see figure 4), guide rail, lifting platform dovetail, guide rail, workbench dovetail, guide rail, saddle dovetail, guide rail, for the size difference of workpiece, the size of cutterhead must adapt to it, and the milling cutter quantity in the combining structure can be done an amount of increase and decrease according to the designing requirement of workpiece.

Because the utility model adopts combining structure, can make the processing one-shot forming of workpiece, saving of work and time when for a certain blade in the profile milling cutter wearing and tearing taking place, can be changed pointedly, does not need globality to change and causes the waste of material and cutter.

Claims

1, a kind of dovetail profile milling cutter is characterized in that the dovetail profile milling cutter by face cutter (101), angle cutting tool (105), and dovetail cutter (106), it is superimposed in regular turn to cut slotting cutter (107), and superimposed back is by the positioning core axle location, and the back, location is by the fixing typing of connector screw.

2, dovetail profile milling cutter according to claim 1 is characterized in that, bonding pad is arranged between the milling cutter when superimposed.
