Spindle Unit Modular Drive for Quick Motor Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool configurations require significant time for replacing drive motors due to complex setups and numerous parts that need to be detached and reassembled, complicating the motor replacement process in spindle and table units.
Innovation Solution
The spindle and table units are designed with first and second power transmission mechanisms and drive source devices arranged in parallel, with taper gears and offset output shafts, allowing for direct detachment and attachment of drive source devices through dedicated holes in the side walls, simplifying the replacement process and reducing assembly time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex drive system configuration is used to transmit rotational drive power to the tilt shaft, then the drive function is achieved, but the time required for replacing the motor increases significantly
Solution Approach 1:
The drive system is segmented into modular components: drive source devices with output shafts, power transmission mechanisms with gears, and tilt shaft assemblies. Each module can be independently replaced, allowing the motor to be changed without dismantling the entire drive system. The segmentation enables quick detachment and attachment of individual components.
Solution Approach 2:
The drive source device is extracted as a separate, removable module from the main spindle head support structure. The output shaft of the drive source device can be detached from the power transmission mechanism, allowing the motor to be replaced independently without affecting other parts of the system.
2Volume of moving object
If multiple parts are arranged in a compact configuration to save space, then the device size is reduced, but the complexity of assembly and disassembly increases
Solution Approach 1:
The compact device is divided into standardized modular segments that can be quickly assembled and disassembled. The drive source device, power transmission mechanism, and tilt shaft are separate modules that fit together in a compact arrangement but can be independently removed and replaced.
Solution Approach 2:
Mounting holes are pre-positioned in the side walls of the spindle head support, and mounting protrusions are pre-formed on the drive source devices. These preliminary structural features enable rapid attachment and detachment without requiring complex alignment procedures during assembly.
3Reliability
If drive source devices are arranged in parallel with offset output shafts, then the tilt shaft can be driven from both sides, but the configuration becomes more complex
Solution Approach 1:
The drive source devices are arranged asymmetrically in parallel positions with offset output shafts, allowing each drive source to independently drive the tilt shaft from different sides. The asymmetric arrangement is compensated by the symmetric power transmission mechanisms (gears) that transfer power to the common tilt shaft.
Solution Approach 2:
Power transmission mechanisms acting as intermediaries (gears) are introduced between the drive source devices and the tilt shaft. These intermediaries transfer and synchronize the rotational motion from the offset output shafts to the tilt shaft, enabling coordinated operation despite the asymmetric arrangement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables quick and easy replacement of tilt shaft drive motors, reducing the time required for motor changes and improving operational efficiency by minimizing the need for extensive disassembly and reassembly.
Implementation Method 1
The first and second power transmission mechanisms have taper gears (11a, 11b, 12a, 12b) attached to the output shafts (15a, 15b) of the first and second drive source devices (7, 8), respectively
