Abstract
The utility model provides a boring cutter row used for machining large-diameter inner holes. The boring cutter row used for machining large-diameter inner holes comprises a center fixing ring and is characterized in that a row wing is welded to one end of the center fixing ring, an end wing is welded to the other end of the center fixing ring, reinforcing ribs are welded between the center fixing ring and the row wing as well as between the center fixing ring and the end wing, the end of the row wing and the end of the end wing are respectively provided with a boring cutter clamping installation hole, and the axis of the boring cutter clamping installation hole in the row wing is perpendicular to the axis of the boring cutter clamping installation hole in the end wing. The boring cutter row is light in overall weight and large in torque, and a single boring cutter can be adjusted within a certain range so as to machine the inner holes with different diameters.
Description
technical field:
The utility model relates to a kind of for processing the boring cutter row of larger diameter internal bore, belongs to machining equipment technical field.
background technology:
Before small turbine, a representative workpiece of cylinder block is the about 1320mm in this part large aperture, the large about 746mm of hole depth, and the minimum about 500mm in small-bore, the complete about 1200mm of hole axial dimension, has many blade annular grooves to need processing in large aperture.This workpiece complex contour, on vertical car, processing and loading clamp is more complicated, time-consuming, and two large small-bores differ larger, axial dimension surpasses 1.2 meters, so the process of turning, except time-consuming, in-process gaging often, and be difficult for measuring, so working (machining) efficiency is low, operator's knack attainment also to be had relatively high expectations, quality is a little difficult control.In the time concentrating batch production cylinder block, two numerical control vertical lathes are often loaded and have heavily been formed the critical bottleneck of the production schedule.Utilize numerical control large floor boring machine to substitute vertical car to complete the processing of the front and back cylinder block of cylinder, get through bottleneck, greatly improve crudy and raise the efficiency, but the processing of cylinder before and after the configuration of the standard frock cutter of existing numerical control borer can not meet naturally, the axial length in hole is crossed 1.2 meter rulers cun, and the rigidity of boring axle even can not show a candle to vertical tool holder.These sizes are to some difficulty of the processing of existing numerical control floor boring machine, macropore diameter super large, and existing boring cutter row can not satisfy the demands.
summary of the invention:
The purpose of this utility model is to provide for the problem of above-mentioned existence that a kind of overall weight is light for processing the boring cutter row of larger diameter internal bore, and moment of torsion is large, and single boring cutter can regulate within the specific limits, to meet different-diameter processing.
Above-mentioned object realizes by following technical scheme:
For processing the boring cutter row of larger diameter internal bore, comprise center retainer plate, described retainer plate one end, center is welded with row's wing, the other end is welded with the end wing, between described center retainer plate and described row's wing, the end wing, be welded with respectively reinforcement, the termination of described row's wing and the described end wing has respectively boring cutter and clamps hole, and the axis that the boring cutter on described row's wing clamps hole is vertical with the axis that the boring cutter on the described end wing clamps hole.
Described for processing the boring cutter row of larger diameter internal bore, on described center retainer plate, there is the keyway coordinating with boring axle, on described center retainer plate, there is the bolt mounting holes one connecting with described keyway.
Described for processing the boring cutter row of larger diameter internal bore, on described center retainer plate, there is one group of bolt hole two.
brief description of the drawings:
Fig. 1 is top view of the present utility model.
Fig. 2 is front view of the present utility model.
In figure 1, center retainer plate; 2, row's wing; 3, the end wing; 4, reinforcement; 5, boring cutter clamps hole; 6, keyway; 7, bolt mounting holes one; 8 bolts hole two.
detailed description of the invention:
Of the present utility model for processing the boring cutter row of larger diameter internal bore as shown in Figure 1-2, comprise center retainer plate 1, described retainer plate one end, center is welded with row's wing 2, the other end is welded with the end wing 3, between described center retainer plate and described row's wing, the end wing, be welded with respectively reinforcement 4, the termination of described row's wing and the described end wing has respectively boring cutter and clamps hole 5, and the axis that the boring cutter on described row's wing clamps hole is vertical with the axis that the boring cutter on the described end wing clamps hole.Because aperture is large, boring cutter row of the present utility model is also very large, from the termination of row's wing to holding the termination length of the wing greatly about 1200mm left and right, therefore it is necessary alleviating component, so boring cutter row of the present utility model is designed to aluminium welding structural element, be directly enclosed within boring shaft end bolt fastening, with two 36mm key piece transmitting torques, single boring cutter can regulate within the specific limits, to meet different-diameter processing.
Described for processing the boring cutter row of larger diameter internal bore, on described center retainer plate, there is the keyway 6 coordinating with boring axle, on described center retainer plate, there is the bolt mounting holes 1 connecting with described keyway.
Described for processing the boring cutter row of larger diameter internal bore, on described center retainer plate, there is one group of bolt hole 28.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises by above technical characterictic and is equal to the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to those skilled in the art's common practise.
