Problems solved by technology
[0002] Most crankshaft main journals are designed with straight oil holes. There are several main journals of multi-cylinder crankshafts with straight oil holes. For example, four-cylinder crankshafts have five main journals and four main journals have straight oil holes. When using a drilling machine to process one by one, the efficiency is low and the labor intensity is high. In mass production, multiple machine tools must be equipped to ensure the production cycle. Some crankshaft processing factories use special machines. The manufacturing cost of this special machine is high and expensive, and it is only suitable for a single type of crankshaft. Not convenient for multi-variety and small-batch production

The invention relates to a special device which utilizes a reconstituted old lathe to drill a crankshaft straight oilhole, wherein a drill (10) is rotated through a lathe spindle (2), a core shaft (3), a spindle universal coupling (4), a transmission case body (5), a drilling head universal coupling (6), a drilling head (8) and a drill chuck (9), a lathe lead screw (12) drives a tool on a lathe slide carriage (11) to realize a feed motion, so the crankshaft straight oilhole drilling is completed. The number of output shafts of the transmission case body can be designed according to the number of the crankshaft straight oilholes to be processed. The position of the drilling head on a fixing plate of the drilling head is designed according to the centre distance of the crankshaft straight oilholes to be processed. The device can be used for simultaneously processing the crankshaft straight oilholes through one-time clamping, so the working efficiency is improved by 4 times compared with the original device; the device is suitable for processing a small batch of various crankshafts; the labor intensity is relieved, and the number of drilling machines is reduced, and the power consumption is saved; the old device is repaired, the waste materials are reclaimed, so the investment is saved.
Description
Technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and specifically relates to a crankshaft drilling straight oil hole device. Background technique [0002] Most crankshaft main journals are designed with straight oil holes. For multi-cylinder crankshafts, several main journals have straight oil holes. For example, four-cylinder crankshafts have five main journals and four main journals have straight oil holes. In the past, straight oil holes were processed. Drilling machines are often used to process one by one, which is low in efficiency and labor-intensive. In mass production, multiple machine tools are required to ensure the production cycle. Some crankshaft processing plants use special machines. This special machine is expensive to manufacture and is only suitable for a single variety of crankshafts. It is not convenient for the production and use of multiple varieties and small batches. Summary of the invention [0003] The tec...
