Description
Technical field
The invention belongs to bearing pin processing technique field, and in particular to a kind of bearing pin fast turning device.
Background technology
The turning to bearing pin is carried out using engine lathe, typically will be by more than two knives or two knives could be by bearing pin turning
Shaping, the serious influence production efficiency of meeting, increases production cost, and the annual turning mining pin shaft month more than 14000 of my company 2016 is propped up,
Bearing pin according to φ 60*300 is calculated, and average turning has always a demand for half-hour period, and having 5 engine lathes carries out turning
Bearing pin, turning and completing above-mentioned bearing pin needs 5 people and the 5 chassis bed could to complete reluctantly for 180 days altogether.Because of the tradition of engine lathe
Turning process causes turning speed too slow, and strong influence operating efficiency and client govern to the problem of goods construction period
To the development of class processing enterprise.
The content of the invention
The present invention is in order to solve traditional lathe in batch turning bearing pin, because engine lathe tradition turning process causes car
Cut that speed is too slow, strong influence operating efficiency and client are to the problem of goods construction period and then fast there is provided a kind of bearing pin
Fast truning fixture.
The present invention is adopted the following technical scheme that：
A kind of bearing pin fast turning device, including main frame body, the first turning cutting tool and the second turning cutting tool, main frame body are installed on car
On bed, the first turning cutting tool and the second turning cutting tool are parallel to each other, edge of a knife setting direction is identical, and the first turning cutting tool is by flexible
Knife rest is installed on main frame body, and the first turning cutting tool is adjustable with respect to the radial feeds of bearing pin, and the second turning cutting tool is by fixing
Knife rest is fixedly installed on main frame body, the radial feeds of relative bearing pin are fixed；The radial feeds of second turning cutting tool
More than the maximum radial amount of feeding of the first turning cutting tool, and the turning cutting tool of direction of feed second is located at the first turning knife to axial
Tool rear.
The flexible knife rest uses the cylinder barrel of telescopic oil cylinder, telescopic oil cylinder to be fixedly installed on main frame body, the first turning knife
Tool is installed on piston rod top, and main frame body is provided with the hydraulic system electric-controlled switch of control telescopic oil cylinder piston rod action.
Cooling spraying device is installed, cooling spraying device is comprised at least after atomizing inlet mouthful water inlet on the main frame body
Two cooling spray loops a, loop cools down the first turning cutting tool, and another loop cools down the second turning cutting tool, on main frame body
It is provided with the cooling system electric-controlled switch of control cooling spraying device.
The turning control process of the truning fixture is：
The first step, by the device integral installation on the knife rest of lathe, the axial feed of the device uses the feeding system of former lathe
System, after adjusting first time axial feeding and radial feeds, opens cooling system electric-controlled switch；
Second step, starts turning, and the device is overall to be moved along lathe axial direction direction of feed by the setting amount of feeding, the first turning cutting tool
Just car is carried out to being turned on bearing pin material, Lathe quantity is d1, and the second turning cutting tool carries out secondary turning, car to the bearing pin material after first car
The amount of cutting is d2, realizes single axial feed, cuts twice；
3rd step, according to the shape and structure of bearing pin termination, after the first turning cutting tool turning to bearing pin termination specified location, presses
Hydraulic system electric-controlled switch, oil cylinder shrinks and drives the first turning cutting tool to leave cutting position and is retracted in main frame body, treats second
After turning cutting tool turning to the specified location of bearing pin termination, stop turning and cooling system electric-controlled switch, complete this feeding car
Cut；
4th step, adjusts the amount of feeding again, and flexible knife rest is stretched out again, opens cooling system electric-controlled switch, repeats above-mentioned second
Three steps, until pin diameter meets design requirement.
The radial cutting amount of described axial feed of bearing pin fast turning device（d1+ d2）It is 6-7mm.
The present invention has the advantages that：
1st, axial feed, twice radial cutting can be realized once using the device, increases the cutting output of single formation, relatively passed
The system technique turning bearing pin time saves more than 60%.For example, by 2 people and 2 chassis bed 180 workloads that could be completed, this dress
The manufacturing cost put is 680 yuan/set, and an engine lathe needs more than 150,000 yuan, and a wage for workmen is 140 yuan/day, so may be used
Directly to save expenses of labour：180 days=75600 yuan of * 3 people * of 140 yuan/day+purchase lathe expense：150000 yuan/platform * 2=300000 units
+ the electricity charge and other loss 60 yuan/day * 3*180=32400 unit=408000 yuan, the two present apparatus that compares substantially save the time,
Production cost is reduced, carrying out traditional turning process costs using engine lathe can have a strong impact on the development of enterprise.
2nd, the device is in addition to it can be used to process bearing pin, it can also be used to the processing of the component such as axle class, piston rod class, as long as relating to
And axial feed, radial cutting are generally applicable.
