Problems solved by technology

[0002] In the prior art, the chamfering of the center hole of the crankshaft shaft end is completed by an ordinary drilling machine. When chamfering, the crankshaft is first clamped with a clamp, and then the chamfering bit is moved downwards. After the chamfering bit moves in place, the chamfering is performed. The positioning accuracy of the chamfering method is not high, and it is easy to cause chamfering. In addition, due to the high strength and hardness of the crankshaft, the chamfering drill needs to use special cooling oil. The existing cooling oil oiling method is all through manual brushes. Apply it on the drill bit, and apply it once for each chamfer, which is labor-intensive and time-consuming

Abstract

The invention discloses a chamfering device for a central hole of a crankshaft. The chamfering device comprises a chamfering workbench, wherein a crankshaft clamping plate and a chamfering instrument are arranged on the chamfering workbench; the chamfering instrument comprises a chamfering drill bit, a drill chuck and a driver; a driver bracket is arranged on the chamfering workbench; the driver bracket comprises a support frame and a rotating shaft arranged on the support frame; a connecting rod is arranged between the rotating shaft and the driver; a cooling oil supply column is arranged on the chamfering workbench; the height of the cooling oil supply column is as same as that of the crankshaft. The chamfering device provided by the invention can quickly and effectively complete the chamfering tasks for the central holes in the two ends of the crankshaft. The chamfering device is higher in chamfering precision and excellent in cooling effect.

Description

technical field [0001] The invention relates to a chamfering device, in particular to a chamfering device for a crankshaft center hole. Background technique [0002] In the prior art, the chamfering of the center hole of the crankshaft shaft end is completed by an ordinary drilling machine. When chamfering, the crankshaft is first clamped with a clamp, and then the chamfering bit is moved downwards. After the chamfering bit moves in place, the chamfering is performed. The positioning accuracy of the chamfering method is not high, and it is easy to cause chamfering. In addition, due to the high strength and hardness of the crankshaft, the chamfering drill needs to use special cooling oil. The existing cooling oil oiling method is all through manual brushes. Apply it on the drill bit, and apply it once for each chamfer, which is labor-intensive and time-consuming. Contents of the invention [0003] In view of this, the object of the present invention is to provide a cranksh...
