Description
Technical field
The utility model relates to brake drum manufacturing technology field, is specifically related to a kind of gang tool for processing automobile brake drum bottom surface
Background technology
The similar peviform of automobile brake drum drum body global shape, be generally pure Mechanical processing of casting and form, in vehicle actual travel process, the frequency of utilization of brake drum is higher.Automobile brake drum comprises brake drum openend and brake drum bottom surface, the process of current brake drum bottom surface is taked to change cutter and is processed the inside and outside plane of bottom surface respectively, cutter in multiple clamping, change, align the flatness technological requirement that manual operation in process can not ensure inside and outside two planes of bottom surface, cause the prolongation of process time, and badly influence the quality of processing, increase production cost.Therefore, urgently need a kind of gang tool, can realize processing targetedly the inner plane of brake drum bottom surface and outerplanar simultaneously, shorten process time, ensure crudy, thus reach the object saved production cost.
Utility model content
The deficiency that the utility model exists for prior art, provides a kind of structure simple, easy to process, the gang tool for processing automobile brake drum bottom surface, not only shorten process time, improve the crudy of automobile brake drum bottom surface, and improve working (machining) efficiency, reduce processing cost.
The utility model is as follows for solving above-mentioned brake drum bottom surface process technology scheme: a kind of gang tool for processing automobile brake drum bottom surface, comprise cutter and knife rest, it is characterized in that, described cutter comprises the first cutter and the second cutter, described knife rest bottom transverse is provided with cutter groove, institute's cutter groove comprises upper knife groove and lower knife groove, described first, second cutter respectively correspondence is arranged in described upper knife groove and lower knife groove, described first cutter is relative with the edge of a knife of the second cutter, described first cutter is used for the inner plane of processing brake drum bottom surface, described second cutter is used for the outerplanar of processing brake drum bottom surface, described knife rest is also provided with the through hole for being fixed on boring head.
Further, described knife rest is provided with screwed hole, is fixed in described cutter groove by described cutter through described screwed hole by bolt.
When the utility model uses, described knife rest is laterally provided with upper and lower two cutter grooves, by the first Cutting tool installation manner in upper knife groove, second Cutting tool installation manner is in described lower knife groove, then by the screwed hole through knife rest side of bolt respectively, first, second cutter is fixed, be fixedly connected on the boring head of lathe by the through hole on knife rest by knife rest again, boring head band movable knife rack moves, and cutter just can realize processing the inner plane of automobile brake drum bottom surface and outerplanar.
The beneficial effect of this practicality is: structure is simple, easy to process, the automation processing of the inside and outside plane of the bottom surface of automobile brake drum is achieved respectively by first, second cutter be accurately positioned on same knife rest, need multiple clamping with existing cutter, adjust to process respectively with outerplanar the inner plane of bottom surface respectively and compare, not only save the time of processing, meet the technological requirement of the flatness of brake drum bottom surface, and improve production efficiency, achieve reduction production cost.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is machining sketch chart of the present utility model;
In figure, 1, knife rest; 2, upper knife groove; 3, the first cutter; 4, the second cutter; 5, through hole; 6, screwed hole; 7, lower knife groove; 8, brake drum bottom surface; 9, inner plane; 10, outerplanar.
Detailed description of the invention
Be described the principle of this practicality and feature below in conjunction with accompanying drawing, example, only for explaining this practicality, is not intended to limit the scope of this practicality.
As shown in FIG. 1 to 3, a kind of gang tool for processing automobile brake drum bottom surface, comprise cutter and knife rest, described cutter comprises the first cutter and the second cutter, described knife rest bottom transverse is provided with cutter groove, institute's cutter groove comprises upper knife groove and lower knife groove, described first, second cutter respectively correspondence is arranged in described upper knife groove and lower knife groove, described first cutter is relative with the edge of a knife of the second cutter, described first cutter is used for the inner plane of processing brake drum bottom surface, described second cutter is used for the outerplanar of processing brake drum bottom surface, described knife rest is also provided with the through hole for being fixed on boring head.
Described first tool selection model DWLNL2525MO8 clamped cutting bit; Described second tool selection model DWLNR2525MO8 clamped cutting bit.
Described knife rest is provided with screwed hole, is fixed in cutter groove by described cutter through described screwed hole by bolt.
During use, described knife rest is provided with, lower two cutter grooves, by the first Cutting tool installation manner in upper knife groove, second Cutting tool installation manner is in lower knife groove, knife rest is processed with through hole and screwed hole, first cutter and the second cutter are distinguished in the cutter groove of immovable support by bolt through corresponding screwed hole, adjustment first, distance between second cutter and the consistent size needing brake drum bottom surface to process, knife rest uses screw to be fixedly connected with the boring head of lathe by through hole, boring head motion drives the motion of described knife rest, thus drive first, second cutter is processed the inner plane of the workpiece brake drum bottom surface between cutter and outerplanar simultaneously, disposable removal excess stock.
And when carrying out fine finishining to brake drum bottom surface: need the distance first adjusted between first, second cutter to be greater than the size of brake drum bottom surface requirement processing, lower mobile in the vertical direction by boring head band movable knife rack, realize the outerplanar of the second cutter to brake drum bottom surface respectively first to process, then the inner plane of brake drum bottom surface is being processed, finally realizing the fine finishining to automobile brake drum bottom surface.
The foregoing is only the preferred embodiment of this practicality, not in order to limit this practicality, within all spirit in this practicality and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in this practicality.
