A kind of saw blade guide frame for gear grinding machinesTechnical field
This utility model belongs to saw blade processing technique field, particularly relates to a kind of saw blade guide frame for gear grinding machines.
Background technology
Bi-metal bandsaw blades is made up of sawtooth and hump, is mainly used in cutting various metal material, in machine-building, smeltingThe sector applications such as gold, chemical industry, military project are extensive.When saw blade carries out roll flute operation on gear grinding machines, it is necessary to have guider to ensure millThe stability of saw blade during tooth.
Common guider is all made up of two vertical rollers and two pieces of base plates that can regulate, by regulation two piecesDistance between base plate is suitable for the saw blade of each width and passes through.But this device has following defects that the roller system that (1) is verticalBeing required comparison high, abrasion is very fast；(2) the most unsettled during bands for band circulation, reverse the most up and down, damage saw blade.
The Chinese utility model patent that patent publication No. is CN 202667805 U, publication date is 2013.01.16 disclosesA kind of bands for band guider, including base be arranged on base two directive wheels that described saw blade is guided, describedThe front of two directive wheel guiding is provided with the blade support device being fixed on base, and described blade support device is provided with for instituteState the gap that saw blade passes through.
But it is complicated that this utility model exists structure, guide the problem that operation easier is big and guide effect is poor.
Utility model content
The purpose of this utility model is to provide a kind of saw blade guide frame for gear grinding machines, and it can carry out roll flute at saw bladeSaw blade carries out during operation effectively easily guide effect, and it is effective that this utility model has simple in construction, guide easy to operate soonVictory, guide effect is good, service life length advantage.
This utility model solves the problems referred to above and the technical scheme is that a kind of saw blade guide frame for gear grinding machines,Including guide frame base, described guide frame base is provided with for carrying out spacing rear alignment unit, use from the saw blade back sideIn carry out above saw blade side spacing upper limit unit, be arranged on described guide frame base side pilot unit andThe saw blade roll flute machine table slided for saw blade.Guide frame described in this setting is fixed on described saw blade roll flute by spacing for saw bladeIn machine table, and carry out from three directions spacing or guide, it is ensured that saw blade has mobile uniform and stable excellent during roll flutePoint.
Further preferred technical scheme is: described rear alignment unit includes aliging mainboard and being arranged on described alignmentThe mainboard mounting blocks of mainboard rear end, described mainboard mounting blocks is provided with the master corresponding with installing hole on described guide frame basePlate mounting groove.
Further preferred technical scheme is: described mainboard mounting groove is straight-line groove.
Further preferred technical scheme is: described upper limit unit includes being fixed on described guide frame baseSpacing framework and be arranged on the limited block on described spacing framework, described limited block is fixed on described by limited block installing holeSpacing framework is on the side of described pilot unit side.
Further preferred technical scheme is: described limited block is provided with the straight line for regulating described limited block heightMounting groove, the distance between described limited block lower surface and described guide frame base is 0.5-1.5cm.
Further preferred technical scheme is: described limited block installing hole is evenly provided on described spacing framework,Distance between two described straight line mounting grooves in distance between adjacent two described limited block installing holes and described limited blockEqual.
Further preferred technical scheme is: described pilot unit includes being fixed on leading on described guide frame baseTo base and be arranged on the prerotation vane in described guide seats, the quantity of described pilot unit is at least two groups.
Further preferred technical scheme is: described prerotation vane includes prerotation vane fixed part and prerotation vane service portion,Described prerotation vane service portion is arranged on compared to described prerotation vane fixed part near the position of described upper limit unit.
Further preferred technical scheme is: described guide frame base is provided with for discharging removing of roll flute rear impurityMiscellaneous passage.
Further preferred technical scheme is: described saw blade roll flute machine table is provided with for described saw blade guide frameFixing counter sink is installed.
This utility model can carry out guide effect the most easily when saw blade carries out roll flute operation to saw blade, and this practicality is newIt is effective that type has simple in construction, guides convenient to operation, and guide effect is good, service life length advantage.
