Abstract
The utility model discloses a kind of mill arc chamfering device.It comprises the supporting seat of being with connecting hole, is hinged with mill arc chamfering pivoted arm on the supporting seat, establishes abrasive stick on the mill arc chamfering pivoted arm.The cylinder Hole chamfering uses after this mill arc chamfering device, checks that chamfering meets the technological requirement of R0.2 fully.Stopped to scratch the situation of piston and piston ring during the dress piston fully, effectively avoided engine to scratch the hidden danger of the blow-by of piston that causes because of piston and piston ring, because abrasive stick has adopted diamond abrasive, whenever change an abrasive stick and can process 30000 cylinder bodies, effectively raise production efficiency and reduce cost; It is simple in structure, and it is low to make production cost; This mill arc chamfering device principle can not only be used for cylinder hole rounding arc angle, and can be used on the circular hole circular arc chamfering in other a large amount of productions.
Description
Technical field
The utility model is located at machine tools, is specifically related to a kind of hole interior angle mill arc facing attachment that is used for.
Technical background
At present, the cylinder body cylinder Hole chamfering technological requirement R0.2 of engine, the equipment of finishing this procedure is XF0131 cylinder Hole chamfering special purpose machine tool.The nylon brush that existing use scribbles abrasive material grinds off burr by rotation and finishes chamfering.But because last process is the mill cylinder deck, can produce big burr at edge, cylinder hole in the grinding process, by still leaving big overlap after the nylon brush chamfering.When adorning piston with this cylinder body in the cylinder hole, the overlap at edge, cylinder hole will scratch piston and piston ring, and causes engine to have the hidden danger of blow-by of piston.
Summary of the invention
The purpose of this utility model is to provide a kind of mill arc chamfering device that is directly installed on the circular hole facing attachment, addresses the above problem.
The technical solution of the utility model is: mill arc chamfering device comprises the supporting seat of being with connecting hole, is hinged with mill arc chamfering pivoted arm on the supporting seat, establishes abrasive stick on the mill arc chamfering pivoted arm.
The cylinder Hole chamfering uses after this mill arc chamfering device, checks that chamfering meets the technological requirement of R0.2 fully.Stopped to scratch the situation of piston and piston ring during the dress piston fully, effectively avoided engine to scratch the hidden danger of the blow-by of piston that causes because of piston and piston ring, because abrasive stick has adopted diamond abrasive, whenever change an abrasive stick and can process 30000 cylinder bodies, effectively raise production efficiency and reduce cost; It is simple in structure, and it is low to make production cost; This mill arc chamfering device principle can not only be used for cylinder hole rounding arc angle, and can be used on the circular hole circular arc chamfering in other a large amount of productions.

The specific embodiment
As shown in Figure 1a, mill arc chamfering device is installed on the main shaft 20 of XF0131 cylinder Hole chamfering special purpose machine tool.Mill arc chamfering device comprises supporting seat 1, and perforate 9 on the supporting seat 1, and main shaft 20 passes hole 9 and by bolt 8 supporting seat 1 is fixed on the main shaft 20.By bearing pin 7 hinged mill arc chamfering pivoted arms 3, establish the afterburning torsion spring 2 of grinding of mill arc chamfering pivoted arm on the bearing pin 7 on the supporting seat 1.Shown in Fig. 1 b, mill arc chamfering pivoted arm 7 comprises on two cutter holder bars, 71,72, the two cutter holder bars offers connecting hole 10, connects by bolt 5 between the connecting hole 10.Abrasive stick 4 has adopted diamond abrasive, for "T"-shaped, is clamped in twos between the cutter holder bar by bolt 5.
Its operation principle is shown in Fig. 2,3, when Y-axis 30 is rotated, be that main shaft 20 rotates, be the center of circle with O and apply certain torsion P to abrasive stick, abrasive stick can carry out grinding to the included angle A on flat 32 of hole face 31 and top, when Y-axis is done continuous moving axially downwards, continuous increment variation takes place in the angle α of abrasive stick and end face simultaneously, abrasive stick diagonal angle A wedge angle when the continuous change of α is big partly carries out continuous grinding, Y-axis obtains suitable α ' angle behind certain stroke H downwards, and the sharp corner of angle A will grind suitable circular arc.
