Problems solved by technology
[0004] However, due to the complex structure of this device, large footprint, cumbersome installation technology and operation, the production cycle is long, which affects production efficiency.
At the same time, it is impossible to make the axis of the camshaft coincide with the axis of the camshaft mounting hole of the body to meet the accuracy requirements, which will cause eccentricity, fail to achieve the required positioning accuracy, and the probability of damage to the camshaft bearing bush is very high
[0005] Therefore there is above-mentioned inconvenience and problem in known camshaft assembly method

The invention relates to an assembly device for a cam shaft of a large-sized diesel engine. In the assembly device, a longitudinal sliding rail and a transverse sliding rail are arranged on an operating platform (14); a front support (5) and a rear support (6) are two vertical bars; V-shaped groove blocks with upward openings are arranged on the upper ends of the supports, and a calibration bar (13) or a cam shaft (15) is placed on the front V-shaped groove block and the rear V-shaped groove block; a hand wheel (2) arranged at one side of the operating platform (14) drives the front support (5) and the rear support (6) to move transversely through a screw pair mechanism; the operating platform (14) is connected with a base (12) through four lifting guide pillars (4) positioned at corners, and a lifting mechanism (11) controls lifting guide pillars (4) to rise or fall through a speed reducer (3); and a guide sleeve (1) is inserted on the front end of the cam shaft (15) through a thread. The assembly device has the advantages of greatly improved cam shaft assembly quality and high precision, and being easy and convenient for assembly and operation as well as adjustment.
Description
technical field [0001] The invention relates to a camshaft of a large diesel engine, in particular to an assembly device of the camshaft. Background technique [0002] In the engine, the camshaft is an important part of the valve train, and the camshaft has high requirements on the cam phase angle and axial spacing, so how to ensure the assembly accuracy of the assembled camshaft is extremely important. The existing camshaft assembly is completed by hoisting, and the hoisting mechanism is composed of a power unit and a bracket. The power unit is composed of motor, reducer, clutch, brake, rope drum and wire rope. The support part is composed of a main rod and a rotating arm composed of a screw rod, a jack nut and a vertical rod. [0003] The installation process of the camshaft adopts hoisting: first clamp the camshaft with the clamp installed at the lower end of the hoisting frame and lift it vertically, turn the camshaft box over 90 degrees and place it on the ground, and...
