Description
Technical field
The utility model relates to a kind of right boring crankshaft hole and processes automatic toolsetting control system, is used for the cutter toolsetting control in the high parts hole of boring machine processing diameter required precision.
Background technology
Engine cylinder-body crankshaft hole (or cylinder hole, camshaft hole, balance axis hole) is the crucial working position of engine cylinder-body, the product design hole tolerance is very little-be generally 0.016mm～0.022mm, the right boring crankshaft hole is owing to adopt non-shaping processing, size needs constantly to adjust in the process, could guarantee that machining accuracy is not overproof.Both at home and abroad right boring crankshaft hole (or camshaft hole, balance axis hole) is mostly by artificial toolsetting, adopt artificial toolsetting the tool setting device peace of the band amesdial that school is good can be ridden over fine boring cutter knife bar corresponding position, the measuring contacts of amesdial is got to the peak of point of a knife, block two grooves that are distributed on around the tool rest wherein with special-purpose toolsetting spanner, left rotation and right rotation is adjusted the overhang of boring cutter sheet, changes the size of processing.
Guarantee to process the aperture, require the operator to have consummate technical ability, and labour intensity is big.Therefore, artificial toolsetting is difficult to guarantee that size is not overproof.Many companies are developing automatic toolsetting technology very early, but because its technical difficulty is big, the example of successful Application are aborning arranged seldom.
Summary of the invention
The purpose of this utility model is: because crankshaft hole right boring size is adjusted by artificial, labour intensity is big, and the craftsmanship is required height, and is overproof easily.The purpose of this utility model is that a kind of right boring crankshaft hole of design is processed automatic toolsetting control system, realizes the automatic toolsetting of crankshaft hole, eliminates artificial toolsetting error, alleviates labor strength.
The technical solution of the utility model: right boring crankshaft hole of the present utility model is processed automatic toolsetting control system and is comprised crankshaft hole detection signal collecting part, signal processing, toolsetting operating part, its crankshaft hole detection signal collecting part adopts MARPOSS crankshaft hole self-operated measuring unit, signal processing is right boring crankshaft hole machining tool PMC, and the toolsetting operating part is the knife adjusting device that servomotor drives; The toolsetting signal processing comprises signal acquisition module, comparison module and counting, calculating and output module among the right boring crankshaft hole machining tool PMC; Signal acquisition module is gathered the axis hole detection signal of MARPOSS axis hole self-operated measuring unit, compares with setting value, writes down underproof number and error amount; When underproof number is 2～4 continuously, should organize data and deliver to computing module, computing module is obtained the mean value of 2～4 underproof error amounts, and exports the anglec of rotation number of degrees that this error amount mean value is converted into the knife adjusting device servomotor to the knife adjusting device servomotor; Servomotor drives knife adjusting device and rotates corresponding angle, and knife adjusting device drives tool rest and rotates corresponding angle, and cutter head is adjusted to the right place.
Advantage of the present utility model:
1, adopt signal acquisition process, logic control to realize that automatic toolsetting replaces manual work.
2, correctly use the cutter material, optimize cutting parameter, guarantee the hole surface roughness.
After adopting the utility model, the operator easily realizes the toolsetting operation, guarantees that this key position size is not overproof.Cylinder body crankshaft hole, balance axis hole aperture, surface quality satisfy product requirement fully.Aperture error is controlled in the 0.019mm scope.

The specific embodiment
Fig. 1 is a logic diagram of the present utility model, and Fig. 2 is the logic diagram of signal processing:
Right boring crankshaft hole of the present utility model is processed automatic toolsetting control system and is comprised axis hole detection signal collecting part, signal processing, toolsetting operating part, its axis hole detection signal collecting part adopts MARPOSS axis hole self-operated measuring unit, signal processing is right boring crankshaft hole machining tool PMC, and the toolsetting operating part is the knife adjusting device that servomotor drives; The toolsetting signal processing comprises signal acquisition module, comparison module and counting, calculating and output module among the right boring crankshaft hole machining tool PMC; Signal acquisition module is gathered the axis hole detection signal of MARPOSS axis hole self-operated measuring unit, compares with setting value, writes down underproof number and error amount; When underproof number is 2～4 continuously, generally select continuous 3, should organize data and deliver to computing module, computing module is obtained the mean value of 2～4 underproof error amounts, and exports the anglec of rotation number of degrees that this error amount mean value is converted into the knife adjusting device servomotor to the knife adjusting device servomotor; Servomotor drives knife adjusting device and rotates corresponding angle, and knife adjusting device drives tool rest and rotates corresponding angle, and cutter head is adjusted to the right place.
The automatic knife adjusting device of MARPOSS judges whether to carry out toolsetting according to the aperture comparing data of processing three workpiece continuously, the processing work aperture needs the toolsetting action during less than normal value, the MARPOSS self-operated measuring unit is given machining tool PMC this signal feedback, and machining tool PMC is converted into the action of control signal control knife adjusting device to this signal.Knife adjusting device moves knife adjusting device to boring cutter tool rest cylindrical after by machining tool X, Y to guide rail according to machining tool PMC feedback signal, block the right boring tool rest by the dop of knife adjusting device with three " V " type block structures of its inside, by gear drive cutter holder is rotated to an angle according to feedback signal by servomotor, finish the toolsetting action.
