Abstract
The utility model belongs to machining equipment field, is specifically related to a kind of gang tool, comprises knife bar, is fixed on the cutter on knife bar, and described cutter comprises cutterhead and blade, cutterhead is evenly provided with 4 ~ 6 insert grooves; Described blade comprises blade and boss, and boss is arranged in insert groove; Described cutter head center place is provided with screwed hole; Described knife bar one end outer surface is provided with screw thread, and the other end is provided with keyway, knife bar is positioned at the cutterhead back side and is also provided with limiting plate.Cutter of the present utility model is assembled by cutterhead and blade, instead of integrally-built cutter, in process, blade place often easily damages, once damage, in order to ensure that crudy needs whole cutter to discard, cause waste, too increase processing cost, and the cutter of assembling can change the blade of damage at any time, also can change the cutter of different structure as required, effectively reduce processing cost.
Description
Technical field
The utility model belongs to machining equipment field, is specifically related to a kind of gang tool.
Background technology
When processing engine cylinder-body oil pump hole, need reaming on special purpose machine tool, and reaming cutter used be generally blade and cutterhead is a cutter overall structure, then by Cutting tool installation manner on knife bar, drives knife bar to rotate by boring car and hole.But blade often easily damages in process, in order to ensure crudy, needing to change the cutter damaged in time, causing a large amount of wastes, increasing processing cost.
Utility model content
For solving the problem, the utility model provides a kind of gang tool, and its concrete technical scheme is as follows:
A kind of gang tool, comprise knife bar, be fixed on the cutter on knife bar, described cutter comprises cutterhead and blade, cutterhead is evenly provided with 4 ~ 6 insert grooves; Described blade comprises blade and boss, and boss is arranged in insert groove; Described cutter head center place is provided with screwed hole; Described knife bar one end outer surface is provided with screw thread, and the other end is provided with keyway, knife bar is positioned at the cutterhead back side and is also provided with limiting plate.
Further, the insert groove of described cutterhead is arranged perpendicular to cutterhead edge, on each insert groove, insert groove is provided with bolt hole.
Further, described boss is provided with bolt hole.
Further, described boss stepped, and upper strata step 10 ~ 20mm narrower than lower floor step.
Further, the described blade back side and boss upper surface angle are 15 ~ 30 degree.
Cutter of the present utility model is assembled by cutterhead and blade, in process, if blade damages, can removal of inserts at any time, and do not need to change whole cutter, both ensure that the quality of processing, and avoided again waste, cut down finished cost, in addition, when processing the hole of different pore size or shape, the also replaceable blade with the blade of different size and structure, makes cutterhead to recycle.

Detailed description of the invention
The technical solution of the utility model is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing of the present utility model; clear, complete description is carried out to the technical solution of the utility model; based on the embodiment in the application; other roughly the same embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all should belong to the scope of the application's protection.
A kind of gang tool, described cutter is assembled, in process by cutterhead and blade, if blade damages, can removal of inserts at any time, and do not need to change whole cutter, both ensure that the quality of processing, avoid again waste, cut down finished cost, in addition, when processing the hole of different pore size or shape, the also replaceable blade with the blade of different size and structure, makes cutterhead to recycle.
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
Embodiment one:
As shown in Figure 1 to Figure 3, a kind of gang tool, comprises knife bar 1, is fixed on the cutter on knife bar 1, and described cutter comprises cutterhead 2 and blade 3, cutterhead 2 is evenly provided with 4 ~ 6 insert grooves 4; Described blade comprises blade 5 and boss 6, and boss 6 is arranged in insert groove 4, and the structure of insert groove 4 and boss 6 matches, and leaves opening, makes blade 5 can be extended out cutterhead 2 surface; Described cutterhead 2 center is provided with screwed hole; Described knife bar 1 one end outer surface is provided with screw thread, be connected by threaded engagement between cutterhead 2 with knife bar 1, and adding man-hour, knife bar 1 direction of rotation is consistent with screwed tight direction, avoids cutterhead 2 to come off, and knife bar 1 other end is provided with keyway, rotate at knife bar 1 and add man-hour, can prevent knife bar 1 from loosening with the junction of lathe and knife bar 1 cannot be driven to rotate, knife bar 1 being positioned at cutterhead 2 back side is also provided with limiting plate 7, for limiting the link position of cutterhead 2 and reinforcing the connection of knife bar 1 and cutterhead 2.
Embodiment two:
As Fig. 1 charts shown in 3, a kind of gang tool illustrated by embodiment one, the insert groove 4 of described cutterhead 2 is arranged perpendicular to cutterhead 2 edge, the boss 6 being arranged on insert groove 4 inside is inner along the diameter insertion cutterhead 2 of cutterhead 2 disk, when cutterhead 2 drives boss 6 to rotate, minimum to the pressure effect of blade 3 cell wall, the damage of cutter can be reduced, on each blade 3 groove, insert groove 4 is provided with through hole 8, described boss 6 is provided with bolt hole 9, by the bolt arranged in through hole 8, boss 6 is fixed on insert groove 4 inside; Described boss 6 stepped, and upper strata step 10 ~ 20mm narrower than lower floor step, avoid adding man-hour, blade 3 comes off in insert groove 4, blade 3 is installed more firm; Described blade 5 back side and boss 6 upper surface angle are 15 ~ 30 degree, the blade 5 of other size and dimensions also can be set as required, as long as boss 6 physical dimension is identical, the blade 3 of a replaceable multiple framework of cutterhead 2 and size, save material, reduce processing cost.
Below the utility model is described in detail, the above, be only the preferred embodiment of the utility model, when not limiting the utility model practical range, namely allly do impartial change according to the application's scope and modify, all should still belong in the utility model covering scope.
