Description

Technical Field

[0001] This utility model relates to a crankshaft assembly device for a press, and more particularly to a horizontal assembly and disassembly device for a crankshaft of a press. Background Technology

[0002] According to existing assembly technology, when hoisting a crankshaft, the crossbeam needs to be flipped over along its length and stood upright. For crossbeams longer than 6 meters, there is no safety hazard after flipping and standing upright. However, there is also a risk of damage to the workpiece during the flipping process. When disassembling and repairing the crankshaft later, if the crankshaft is disassembled upright, not only will a large crane be needed to remove the crossbeam module, but the crossbeam also needs to be flipped over and stood upright, resulting in high maintenance costs and considerable time consumption.

[0007] The workpiece beam is provided with an inlet for crankshaft installation, and the center sleeve is located at the inlet;

[0008] The aforementioned intermediate support rods are connected to the workpiece crossbeam.

[0014] Figure 1 This is a schematic diagram of the structure of this utility model.

[0015] In the diagram, 1 is the support rod, 2 is the fixed crossbeam, 3 is the mobile hand chain hoist, 4 is the center sleeve, 5 is the workpiece crossbeam, 6 is the leveling block, 7 is the intermediate support rod, and 8 is the crankshaft. Detailed Implementation

[0016] A horizontal assembly and disassembly device for a press crankshaft, the device comprising a support rod 1, a fixed crossbeam 2, a crankshaft suspension mechanism, a center sleeve 4, a workpiece crossbeam 5, multiple intermediate support rods 7 and multiple height equalizing blocks 6;

[0017] The aforementioned multiple equal-height blocks 6 are arranged below the workpiece crossbeam 5;

[0018] The fixed crossbeam 2 is fixedly connected to the workpiece crossbeam 5, the support rod 1 is connected below the fixed crossbeam 2, the crankshaft suspension mechanism is set on the fixed crossbeam 2, and the crankshaft suspension mechanism is used to suspend the crankshaft 8 and control the crankshaft 8 to be horizontal.

[0019] The workpiece beam 5 is provided with an inlet for the crankshaft 8 to be installed, and the center sleeve 4 is located at the inlet;

[0020] The multiple intermediate support rods 7 are connected to the workpiece crossbeam 5.

[0021] The crankshaft suspension mechanism includes multiple sets of movable hand chain hoists 3, which suspend the crankshaft 8 directly below the fixed crossbeam 2.

[0022] The center sleeve 4 is provided with a wedge-shaped block, which facilitates the contact between the center sleeve 4 and the outer circle of the crankshaft 8 and supports the crankshaft 8.

[0023] The multiple intermediate support rods 7 are respectively arranged between the workpiece crossbeams 5, and the multiple intermediate support rods 7 are placed at the same height.

[0024] The intermediate support rod 7 is equipped with a rotating shaft, which controls the needle rollers on the intermediate support rod 7 to support the crankshaft 8.

[0025] The working process of this utility model is as follows: The workpiece crossbeam 5, support rod 1, and fixed crossbeam 2 are all padded with appropriate height leveling blocks 6. The center sleeve 4 is assembled to the crankshaft 8 inlet end face of the workpiece crossbeam 5. The crankshaft 8 is rotated to be directly below the fixed crossbeam 2. The crankshaft 8 is lifted by three suitable nylon ropes. The crankshaft 8 is kept horizontally stable by three sets of movable hand chain hoists 3. The movable hand chain hoists 3 are slowly pushed to push the front end of the crankshaft 8 into the hole of the center sleeve 4. The wedge blocks in the center sleeve 4 are adjusted to ensure that the needle rollers in the center sleeve 4 contact the outer circle of the crankshaft 8 and support the crankshaft 8. The three sets of movable hand chain hoists 3 and the wedge blocks in the center sleeve 4 are repeatedly adjusted to ensure that the crankshaft 8 can be easily pushed into the workpiece crossbeam 5. When the front end of crankshaft 8 moves to the position of intermediate support rod 7, due to its own weight, the front end of crankshaft 8 will definitely sag, making it difficult to push crankshaft 8 forward further. At this point, by adjusting the rotation axis of intermediate support rod 7, the needle rollers on intermediate support rod 7 are controlled to support crankshaft 8, allowing crankshaft 8 to be reassembled into the workpiece beam 5 until it is pushed to the designated position. Then, release the three sets of movable hand chain hoists 3 and the intermediate support rod 7 to complete the assembly. Disassembly is performed by reversing the operation.
