Diesel engine crank automatic pipe bender

Abstract

The invention discloses a diesel engine crank automatic pipe bender comprising a workbench, a ring-shaped support, a bearing, a torque output shaft, a rotary rod, an air cylinder and an eccentric pipe bending shaft. The workbench face is provided with an eccentric pipe bending shaft hole and a plurality of crank locating holes. An outer ring of the bearing is fixed in the ring-shaped support. The torque output shaft is fixed to an inner ring of the bearing, and the top center of the torque output shaft is provided with a square hole. One end of the rotary rod is fixed to the bottom of the torque output shaft. A connecting rod is hinged to the other end of the rotary rod. A cylinder body is hinged to the workbench. The bottom of the eccentric pipe bending shaft is square and can be inserted into the square hole of the torque output shaft. The eccentric pipe bending shaft rotates along with the torque output shaft. An eccentric rod is arranged at the top of the eccentric pipe bending shaft. The eccentric pipe bending shaft penetrates out from the eccentric pipe bending shaft hole of the workbench. The connecting rod of the air cylinder acts and can drive the eccentric pipe bending shaft to rotate, and finally an oil supply copper pipe can be bent. The installing position of the cylinder body of the air cylinder can be adjusted so that the bending angle of the oil supply copper pipe can be adjusted conveniently. The diesel engine crank automatic pipe bender has the beneficial effects that cost is low, pipe bending is convenient, the pipe bending size can be adjusted, and work efficiency is high.

Description

technical field [0001] The invention relates to an automatic pipe bending machine for a diesel engine crank. Background technique [0002] The crank throw of a diesel engine is one of the three major components in the crankshaft assembly. The crank throw is mainly assembled and connected with the connecting rod. Through the internal combustion and explosion of the piston, the power is pushed to the crankshaft assembly by means of the connecting rod, so that the crankshaft assembly rotates and works. The crankshaft is in contact with the bearing bush, and a layer of lubricating oil will be produced between the crankshaft radius and the bearing bush, and the lubricating oil is provided from the oil hole on the crankshaft radius to satisfy the rotation lubrication between the crankshaft radius and the bearing bush. The two crankshafts need to be connected by bolts, and one of the bolts must pass through the center of the connecting rod shaft. Because there is an oil supply co...

AI Technical Summary

Problems solved by technology

The two crankshafts need to be connected by bolts, and one of the bolts must pass through the center of the connecting rod shaft. Because there is an oil supply copper pipe in the center of the connecting rod shaft, it just blocks the passage of the bolts, so the oil supply copper pipe must be bent to a certain extent. The angle can only be passed. Since the oil supply copper pipe is on the horizontal center of the connecting rod shaft, the two ends are only about the size of the bolt holes. It is impossible to bend it with pipe tools. You can only bend the oil supply copper pipe with a small cylindrical rod

Because the controllability of the above method is not strong, the oil supply copper pipe blocks the bolts and cannot be assembled, the oil supply copper pipe is bent too much, the inner hole of the oil supply copper pipe is squeezed flat, and the oil supply cannot be supplied, so problems such as lava appear.
