Description
Technical field
The present invention relates to the processing of four oilholes on piston of automobile, particularly a kind of device of novel machining piston upper oil hole.
Background technology
Piston of automobile cans be compared to the central position of automobile engine, account for extremely important status when engine start.Piston of automobile is used to bear gas pressure, and orders about crankshaft rotating by piston pin by connecting rod, top land or the part of combustion chamber.And general piston of automobile is divided into: diesel engine piston, piston of gasoline engine, universal piston three major types.
Piston is hat-shaped, is provided with four oilholes on the cylinder of piston and along the circumferencial direction of piston, and four oilholes are uniformly distributed, and these four oilholes are the important feature on piston, and therefore, the position accuracy demand of four oilholes is very high.The method of existing machining piston upper oil hole normally workman is rule in advance on piston, by the drill bit on vertical rig floor, drilling is carried out to line place again, thus complete the processing of four oilholes, but, not only increased the labour intensity of workman by the method for manually ruling, and be easy to line and make mistakes, machining accuracy is caused not reach national standard, product can only be worked as and scrapped, and therefore, does not promote the use of.In addition, piston adopts scroll chuck to clamp piston usually, and the clamping force of scroll chuck is easy to cause piston face to damage, and has a strong impact on the quality of piston, therefore, does not promote the use of.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide that a kind of compact conformation, machining accuracy are high, clamp piston is firm, save the device of the novel machining piston upper oil hole of workman's amount of labour.
Object of the present invention is achieved through the following technical solutions: a kind of device of novel machining piston upper oil hole, it comprises cylinder, stepper motor and reduction box, the output of described stepper motor is connected with the power shaft of reduction box, the output shaft of reduction box is provided with disk, disk is arranged on the outside of reduction box, disk is provided with the lead perpendicular to disk, lead is cylindric, disk is provided with two cylinders perpendicular to disk, two cylinders are symmetricly set on the both sides of lead, the pressing plate perpendicular to lead is provided with between the piston rod of two cylinders.
Described reduction box is made up of cabinet, drive bevel gear and driven wheel of differential, drive bevel gear and driven wheel of differential are all arranged in cabinet, drive bevel gear is connected with power shaft, and driven wheel of differential is arranged on output shaft, and driven wheel of differential engages with drive bevel gear.
The present invention has the following advantages: (1) disk of the present invention is provided with the lead perpendicular to disk, disk is provided with two cylinders perpendicular to disk, two cylinders are symmetricly set on the both sides of lead, the pressing plate perpendicular to lead is provided with between the piston rod of two cylinders, workman only need first by piston bush hole to be drilled on lead, the piston rod controlling two cylinders is again retracted simultaneously, piston is fixed on disk by pressing plate firmly, thus prevent crushing of piston face, ensure that the crudy of piston.(2) automatically a period of time can be stopped after stepper motor of the present invention often rotates 90 °, so that the vertical rig floor of operative carries out the processing of oilhole, automatically 90 ° can be rotated again after stepper motor dwell time terminates, to carry out the processing of second oilhole, circulation like this can process remaining two oilholes, thus ensure that the positional precision of four oilholes, and without the need to ruling on piston, alleviate the labour intensity of workman.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the front view of Fig. 1;
In figure, 1-cylinder, 2-stepper motor, 3-disk, 4-lead, 5-cabinet, 6-drive bevel gear, 7-driven wheel of differential, 8-pressing plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As depicted in figs. 1 and 2, a kind of device of novel machining piston upper oil hole, it comprises cylinder 1, stepper motor 2 and reduction box, described stepper motor 2 can stop a period of time after often rotating 90 ° automatically, so that the vertical rig floor of operative carries out the processing of oilhole, automatically 90 ° can be rotated again, to carry out the processing of second oilhole after stepper motor 2 dwell time terminates.As depicted in figs. 1 and 2, the output of stepper motor 2 is connected with the power shaft of reduction box, the output shaft of reduction box is provided with disk 3, disk 3 is arranged on the outside of reduction box, disk 3 is provided with the lead 4 perpendicular to disk 3, lead 4, in cylindric, disk 3 is provided with two cylinders 1 perpendicular to disk 3, two cylinders 1 are symmetricly set on the both sides of lead 4, are provided with the pressing plate 8 perpendicular to lead 4 between the piston rod of two cylinders 1.
As shown in Figure 1, reduction box is made up of cabinet 5, drive bevel gear 6 and driven wheel of differential 7, and drive bevel gear 6 and driven wheel of differential 7 are all arranged in cabinet 5, and drive bevel gear 6 is connected with power shaft, driven wheel of differential 7 is arranged on output shaft, and driven wheel of differential 7 engages with drive bevel gear 6.
The course of work of the present invention is as follows: when processing oilhole on piston, first by piston bush on lead 4, and make the end face of piston be against on disk 3, the piston rod controlling two cylinders 1 is again retracted simultaneously, piston is pressed on disk 3 by pressing plate firmly, then stepper motor 2 is started, stepper motor 2 drives drive bevel gear 6 to rotate, drive bevel gear 6 drives driven wheel of differential 7 to rotate, driven wheel of differential 7 drives disk 3 to rotate 90 °, now stepper motor 2 stops operating, the workman only drill bit that need operate on desk-top rig floor does feed motion downwards, thus complete the processing of first oilhole, stepper motor 2 starts automatically again subsequently, workman operates desk-top rig floor drilling second oilhole again, circulation like this just can complete the processing of residue two oilholes.
