Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, easy to operate, applied widely piston heavy boring pin-and-hole centralising device.
For solving above-mentioned technical problem, one piston heavy boring pin-and-hole centralising device of the present invention, including lathe, it is provided with base on described lathe, being provided with rabbet seat on described base, described rabbet seat is arranged above the clamping block being connected with lathe, and described lathe side is provided with boring bar；Described lathe opposite side is provided with " " type base plate, and described " " type base plate is fixed with flap, and described flap is provided with the pin-and-hole centering block relative with boring bar.Need before operation of the present invention to find pin-and-hole centering block position accurately with the standard piston of same model, carry out the heavy boring of blank piston pin hole the most again.Being placed in above rabbet seat by blank piston during pin-and-hole heavy boring, hinge-opening plate, on flap, the pin-and-hole centering block of location is relative with the pin-and-hole of blank piston, starts the HYDRAULIC CONTROL SYSTEM clamping block clamping piston of lathe；After piston realizes clamping position, lathe boring bar side translation in operation, boring bar is to piston pin hole heavy boring, when boring bar touches pin-and-hole centering block and persistently pressure is touched, flap closure；Boring bar exits pin-and-hole and completes one-stop operation.Blank piston pin hole before clamping can be accurately positioned by the pin-and-hole centering block of the present invention, improves pin-and-hole heavy boring precision, it is ensured that product quality.
Preferably, described rabbet seat is Height Adjustable.It can realize high being adjusted flexibly in seam center, and convenient working improves working performance simultaneously.
Preferably, described flap is flexibly connected with " " type base plate and flap can be along " " type base plate anterior-posterior translation；Described pin-and-hole centering block is flexibly connected with flap and pin-and-hole centering block can be along flap upper and lower translation；Described " " type base plate is flexibly connected with lathe and " " type base plate can translate along about lathe.Technique scheme is applicable to the blank Piston Machining of different model, and the pin-and-hole centering block center height mated with pin-and-hole is adjustable, interchangeable, adapts to difference and compresses the blank Piston Machining of high and different pin-and-hole diameter, easy to operate, applied widely.
Preferably, described flap fixes bolt by flap, flap bar hole is flexibly connected with " " type base plate；Described pin-and-hole centering block fixes bolt by centering block, centering block bar hole is flexibly connected with flap；Described " " type base plate fixes bolt by base plate, base plate bar hole is flexibly connected with lathe.Through production practices, this technical scheme can improve notable operation work efficiency, ensures pin-and-hole heavy boring precision and the stability of operation.
To sum up, present configuration is simple, easy to operate, while improving piston pin hole heavy boring work efficiency, it is achieved the lifting of pin-and-hole heavy boring precision, and the constant product quality of its processing.

Detailed description of the invention
The present invention is further illustrated below in conjunction with the accompanying drawings:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, one piston heavy boring pin-and-hole centralising device of the present invention, including lathe 1, it is provided with base 2 on described lathe 1, it is provided with rabbet seat 3 on described base 2, described rabbet seat 3 is arranged above the clamping block 4 being connected with lathe 1, and described lathe 1 side is provided with boring bar 9；It is characterized in that: described lathe 1 opposite side is provided with " " type base plate 5, described " " type base plate 5 is fixed with flap 6, and described flap 6 is provided with the pin-and-hole centering block 7 relative with boring bar 9.
Described rabbet seat 3 Height Adjustable.
Described flap 6 is flexibly connected with " " type base plate 5 and flap 6 can be along " " type base plate 5 anterior-posterior translation；Described pin-and-hole centering block 7 is flexibly connected with flap 6 and pin-and-hole centering block 7 can be along flap 6 upper and lower translation；Described " " type base plate 5 is flexibly connected with lathe 1 and " " type base plate 5 can translate along lathe about 1.
Described flap 6 fixes bolt 6b by flap, flap bar hole 6a is flexibly connected with " " type base plate 5；Described pin-and-hole centering block 7 fixes bolt 6d by centering block, centering block bar hole 6c is flexibly connected with flap 6；Described " " type base plate 5 fixes bolt 5b by base plate, base plate bar hole 5a is flexibly connected with lathe 1.
The present invention changes the mentality of designing of conventional piston pin hole centralising device, flap 6, " " type base plate 5, pin-and-hole centering block 7 position is adjustable, it is applicable to the processing of different-diameter blank piston 8, the center height of pin-and-hole centering block 7 is adjustable, interchangeable, is suitable for the different blank piston 8 compressing high and different pin-and-hole diameter and processes.
Embodiment (the pin-and-hole heavy boring of 4100QB-A piston in cloud)
First standard piston is installed on the rabbet seat 3 of lathe 1, adjust " " type base plate 5 to correct position to fix, the pin-and-hole centering block 7 consistent with standard piston specification is selected to be clamped on flap 6, and precision adjusts the optimal center position of pin-and-hole centering block 7 to standard piston pin-and-hole, flap 6 is closed after pin-and-hole centering block 7 is fixing, take off standard piston and same model blank piston 8 is placed in rabbet seat 3, the pin-and-hole of manual unlocking flap 6 to pin-and-hole centering block 7 centering blank piston 8, clamping block 4 compresses blank piston 8 top planes, after manual closing flap 6, boring bar 9 can be to the pin-and-hole heavy boring of blank piston 8, can produce in batches after initial workpiece Product checking is qualified.
