Description

Technical Field

[0001] The invention relates to the technical field of crankshaft drilling, in particular to an engine crankshaft oil hole machining center. Background Art

[0002] The crankshaft is the most important component in the engine. It bears the force transmitted from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsional loads. The lubrication between the crankshaft and the bearing is an important guarantee for the reliable operation of the engine. The function of the crankshaft oil hole is to connect the oil path between the crankshaft and the bearing.

The outer wall of the first threaded rod 9 is threadedly connected to a threaded seat 11 fixed to the first clamping plate 303 toward one end of the I-shaped plate 302. The handle 10 can drive the first threaded rod 9 to rotate and then drive the first clamping plate 303 to move left and right through the threaded seat 11, so that the distance between the first clamping plate 303 and the second clamping plate 306 can be adjusted, so that crankshafts of different sizes can be clamped at the same time, which is convenient for the staff to quickly install and fix the crankshafts and perform processing and drilling. When the crankshaft is processed on the front side, the rear side can not only install and clamp another group of crankshafts, but also clamp and fix crankshafts of different sizes, which has a wide range of applications.

An oil circular groove 704 is provided inside the rotating seat 703, and an oil channel 705 controlled by a solenoid valve to be closed is equidistantly connected to the outer wall of the oil circular groove 704. A drilling machine 706 extending to the outside of the rotating seat 703 is installed inside the oil channel 705. Oil is injected into the oil circular groove 704, and the communication with the oil channel 705 can be controlled by a solenoid valve in the prior art. By controlling the oil in the oil circular groove 704 to enter the corresponding oil channel 705, the drilling machine 706 can be driven to move outward to drill the crankshaft.

[0025] like Figure 1-7 As shown, a hydraulic rod 18 is installed at one end of the connecting seat 702, and the telescopic end of the hydraulic rod 18 passes through the oil circular groove 704 and is connected to a push plate 19. A driving device 20 for driving the rotating seat 703 to rotate is installed at one end of the other group of connecting seats 702. The set driving device 20 can control the rotation of the rotating seat 703 so that the drilling rigs 706 set equidistantly on the outside are oriented to the position where the hole needs to be drilled, and then the push plate 19 is driven by the set hydraulic rod 18 to squeeze the oil into the oil channel 705 opened by the solenoid valve, so that the corresponding drilling rig 706 can move to the outside.

[0026] like Figure 1-7 As shown, a mounting rod 21 is connected to the center of one end of the I-shaped plate 302 facing the connecting plate 305, and a Z-shaped plate 22 is installed on the outer wall of the mounting rod 21.

[0027] Working principle: When in use, the first clamping plate 303 and the second clamping plate 306 can clamp and fix two groups of crankshafts, and the electric rod 301 can drive the I-shaped plate 302 to move toward the connecting plate 305 so as to clamp and fix crankshafts of different sizes, and the flip motor 304 can rotate the processed crankshaft to the rear side, and the crankshaft on the rear side can be rotated to the front side for processing, saving time and improving efficiency. The handle 10 can drive the first threaded rod 9 to rotate and then drive the first clamping plate 303 to move left and right through the threaded seat 11, so as to adjust the distance between the first clamping plate 303 and the second clamping plate 306, so as to clamp crankshafts of different sizes at the same time, which is convenient for the staff to quickly install and fix the crankshafts and perform processing and drilling. When processing the crankshaft on the front side, the rear side can not only install and clamp another group of crankshafts, but also clamp and fix crankshafts of different sizes. The crankshaft has a wide range of applications. The oil circular groove 704 is filled with oil, and the communication with the oil channel 705 can be controlled by the solenoid valve in the prior art. By controlling the oil in the oil circular groove 704 to enter the corresponding oil channel 705, the drill 706 can be driven to move outward to drill the crankshaft. The driving device 20 can control the rotating seat 703 to rotate so that the drill 706 equidistantly arranged on the outside is directed to the position where the hole needs to be drilled. Then, the push plate 19 is driven by the hydraulic rod 18 to squeeze the oil into the oil channel 705 opened by the solenoid valve, so that the corresponding drill 706 can move outward. The Z-shaped plate 22 can separate the crankshaft after clamping and fixing. The waste chips splashed by the crankshaft during drilling will not affect another group of crankshafts, and one end of the Z-shaped plate 22 is always under the crankshaft during drilling to collect the waste chips.
