Abstract
The utility model discloses a boring tool device. The device comprises a boring bar connected with a power output shaft of a machine tool. A plurality of machining gears are arranged on the boring bar. Each machining gear is provided with a plurality of boring tools. Compared with the prior art, the boring tool device has the advantages that: the plurality of boring tools are arranged on the boring bar, so that the boring tools work all the time during machining, the stressed condition of a workpiece is uniform and steady, the stability of the machining quality is effectively improved and the machining efficiency is improved simultaneously.
Description
Technical field
The utility model relates to a kind of boring cutter device, relates in particular to a kind of boring cutter device that is suitable for processing semicircle orifice.
Background technology
In machine-building, often need the endoporus of processing semi-circular shape, such as the processing of cylinder of diesel engine axis hole.To this class endoporus, the processing of general in the past employing straddle mill.The defective of this processing unit (plant) is that the processing resistance is excessive, causes the crudy instability, influences the distribution of the allowance of next procedure, very easily produce substandard product, and working (machining) efficiency is low.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of boring cutter device, and working angles is more stable when using this device processing semicircle orifice, and can effectively improve machining accuracy and working (machining) efficiency.
For solving the problems of the technologies described above, the boring cutter that the utility model provides has following structure:
A kind of boring cutter device comprises the boring bar that is connected with the power output shaft of lathe, it is characterized in that, described boring bar is provided with a plurality of processing shelves, and each processing shelves is equipped with many boring cutter.
Preferably, described boring bar is provided with seven processing shelves.
Preferably, on each processing shelves two boring cutters are installed on the described boring bar.
Preferably, two boring cutters on described each processing shelves are 180 degree distributions on the circumference of boring bar.
Compared with prior art, the utility model is many boring cutter by being provided with on boring bar, and make has boring cutter man-hour in work adding always, and workpiece is stressed uniform and stable, has improved the stability of crudy effectively, has also improved simultaneously working (machining) efficiency.
Description of drawings
Fig. 1 is the assembling schematic diagram of the utility model under user mode;
Fig. 2 is the left view of Fig. 1.
The Reference numeral that is identified in the above-mentioned accompanying drawing is respectively:
The 1-boring bar; The 2-boring cutter; The 3-bearing block; The 4-housing screw; 5-location rhombus pin; The 6-rest pad; The 7-clamping fixture seat; The 8-boring cutter; 9-positioning round pin; The 10-cylinder block; 11-cylinder block semicircle orifice.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.
Illustrated in figures 1 and 2 is a kind of and the matching used boring cutter device of lathe, and this boring cutter device is used to process the spindle hole 11 of engine cylinder block 10.This boring cutter device comprises a cylindrical boring bar 1 of step, one end of boring bar 1 is connected with the power output shaft of lathe, when starting lathe, boring bar 1 can move as feed motion towards axial direction with as main motion under the drive of the power output shaft of lathe simultaneously in rotation.The two ends of boring bar 1 are subjected to the fixing of bearing block 3, and described bearing block 3 is fixedly set on the workbench.Described boring bar 1 is provided with seven and processes shelves, and each processing shelves is equipped with two boring cutters 2, and two boring cutters 2 are 180 degree distributions on the circumference of boring bar 1.
Wherein, the handle of a knife of boring cutter 2 is a rectangular shape, after installing by the square opening on the boring bar 1, uses 4 pairs of boring cutter cutters that are fixedly clamped of cutter housing screw.To this operation, the operator can adjust according to the requirement of process size in the machining.
During the processing cylinder block, cylinder block 10 is lifted this device top by suspender, slowly cylinder block 10 is fallen, cylinder block 10 is located by location rhombus pin 5 and positioning round pin 9 on the clamping fixture seat 7, placing four supporting block for locations 6 simultaneously on workbench supports as cylinder block, clamp the end face of cylinder block 10 then, thereby finish location, the clamping of cylinder block 10 at this device.After exhaust hood body 10 is installed, can starts machine tool and make boring bar 1 do rotation and axial linear movement is carried out the processing of cylinder block spindle hole 11.
Because being 180 degree on the circumference of boring bar 1, boring cutter 2 distributes, thereby guaranteed in process, to have remained a boring cutter 2 in work, realized the continuous machining of the spindle hole 11 semicircle blanks of 2 pairs of cylinder of diesel engine 10 of boring cutter, improve working (machining) efficiency, also avoided simultaneously using one boring cutter added to be easy to generate vibration, the unsettled shortcoming of crudy man-hour.
This device also can be advantageously used in processing semicircle orifice or the borehole structure on other products.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
