Description

Omnipotent milling overarm tooth bar milling tool

Technical field

The utility model relates to machinery manufacturing technology field, especially a kind of frock for the milling of omnipotent milling overarm tooth bar.

Background technology

In universal knee-and-column milling machine, the gear engagement on overarm rack and pinion axle, by the handle drives of the gear shaft other end, realizes overarm and moves forward and backward, and to realize in overarm, arbor support is installed, and improves the rigidity of milling arbor, guarantees the machining accuracy of part.This rack-driving is manual transmission, and therefore the requirement of tooth bar accuracy class is 9 grades.

When without special equipment, it is more difficult that processing length exceedes the tooth bar flank of tooth of 400 millimeters, at present 1000 millimeters of above tooth bars is normally adopted and connects cutter, design tooth bar milling head, repacking and turn to knife rest or design taper slotting cutter to process.In addition also have a lot of frocks, one of them is to install end mill head additional in omnipotent milling, the angle relevant to tooth bar pressure angle tilts, then with three sword dish milling cutters or metal saw one by one milling press the tooth bar of the longitudinal clamping of workbench, again by 180 ° of tooth bar reversions, repeat above step, finally with slotting cutter, apex angular milling is flat; This kind of method can substantially machine tooth bar without any special equipment and cutter in the situation that, but process complexity is loaded down with trivial details, adjusts difficulty, and machining accuracy is low, and machining period is long, and working (machining) efficiency is low, high to workman's technical requirement; And adopt other frocks also not reach good Expected Results.

Utility model content

The purpose of this utility model is to provide a kind of omnipotent milling overarm tooth bar milling tool, this omnipotent milling overarm tooth bar milling tool it can to solve overarm tooth bar Milling Processes complexity loaded down with trivial details, adjust difficulty, machining accuracy is low, machining period is long, working (machining) efficiency is low, and the problem high to workman's technical requirement.

In order to address the above problem, the technical solution adopted in the utility model is: this omnipotent milling overarm tooth bar milling tool includes support and end mill body; Described support is fixedly connected with universal milling head by bolt, and described end mill body one end is connected with described support, and the other end is connected with described universal milling head.

In above technical scheme, further scheme is: described end mill body includes milling arbor, is arranged at least two rack milling cutters that separate and locate on described milling arbor and with spacer, and milling arbor threaded one end is connected with locking nut.

Further: described support includes mutual rack connecting plate connected vertically and bracket leg fagging, between described rack connecting plate and bracket leg fagging, be provided with support gusset, described rack connecting plate offers the connecting hole for being connected with described universal milling head, and described bracket leg fagging offers the installing hole for fixing described end mill body.

Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, the utility model installation way becomes horizontal into longitudinally, has greatly increased processing length scope;

2, easy, the easy disassembling of the utility model combination, does not affect the original layout of lathe, easy to adjust, need not reverse, and does not need secondary clamping; Required parts are as universal milling head, the equal buyable of rack milling cutter, and support and spacer are also easy to processing.

3, the supporting role of the utility model support makes milling cutter physical efficiency bear larger cutting force; Can 5 slitting milling cutters millings simultaneously, raise the efficiency, time saving and energy saving.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

The omnipotent milling overarm tooth bar milling tool of Fig. 1, Fig. 2, Fig. 3 and Fig. 4, includes support 3 and end mill body 2; Support 3 is fixedly connected with universal milling head 1 by bolt 4, and end mill body 2 one end are connected with support 3, and the other end is connected with universal milling head 1.Shown in Fig. 5 and Fig. 6, end mill body 2 includes milling arbor 2-1, be arranged on milling arbor 2-1 go up and use spacer 2-4 to separate and locate 5 rack milling cutter 2-2, milling arbor 2-1 threaded one end is connected with locking nut 2-3.Shown in Fig. 7, Fig. 8, Fig. 9 and Figure 10, support 3 includes mutual rack connecting plate 3-1 connected vertically and bracket leg fagging 3-3, between rack connecting plate 3-1 and bracket leg fagging 3-3, be provided with support gusset 3-2, rack connecting plate 3-1 offers the connecting hole for being connected with universal milling head 1, bolt 4 is fixedly connected with support 3 by these connecting holes with universal milling head 1, bracket leg fagging 3-3 offers the installing hole for fixing end mill body 2, end mill body 2 one end are arranged on this hole, and the other end is connected with universal milling head 1.

To first installing support before tooth bar processing on universal milling head, notice guaranteeing that bracket holes axis overlaps with main-shaft axis; Add man-hour, overarm length direction is consistent with workbench longitudinal direction, is fixed on workbench, and 5 rack milling cutters are contained on milling arbor together, separates with spacer, and milling arbor, through use nut check after bracket holes, just can be processed after centering starting point; 5 tooth aftertables of every milling laterally exit, 5 times of pitches of length feed, then repeat milling.
