Dual-Motor Machining Assembly With Cable-Free Feed Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining assemblies for drilling into hard materials, such as concrete, often require separate housings for the drive motor and feed motor, leading to increased weight, size, and complexity, as well as the need for electric cables in the feed module.
Innovation Solution
A machining assembly with a drive unit housing containing both the drive motor and feed motor, eliminating the need for separate housings and electric cables in the feed module, and allowing for automatic movement along a guide track using a torque-transmitting coupling mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate housings are used for drive motor and feed motor, then functional separation is achieved, but weight and size increase
Solution Approach 1:
The patent combines the drive motor and feed motor into a single common housing, eliminating the need for separate housings. This merging approach reduces the overall weight and size of the machining assembly while maintaining all necessary functions, directly resolving the contradiction between functional separation and weight reduction.
Solution Approach 2:
The common housing serves multiple functions by accommodating both the drive motor and feed motor, as well as providing structural support and mounting points. This multi-functional design eliminates redundant components and reduces overall weight while maintaining functional integrity.
2Ease of manufacture
If separate housings are used for drive motor and feed motor, then functional separation is achieved, but device complexity increases
Solution Approach 1:
By merging the drive motor and feed motor into a single housing, the patent reduces the number of separate components and assembly steps. This simplifies the overall construction and reduces device complexity while maintaining functional separation through internal arrangement.
Solution Approach 2:
The common housing performs multiple functions including motor mounting, structural support, and cable routing, eliminating the need for separate housings and reducing overall construction complexity.
3Ease of operation
If feed motor is in separate housing, then independent control is achieved, but electric cables are required in feed module
Solution Approach 1:
By placing both motors in the same housing, the patent eliminates the need for electric cables to pass through the feed module. Power and control signals can be routed directly to both motors from a single location, simplifying the electrical architecture while maintaining independent control capability.
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 design reduces the overall weight and size of the machining assembly, simplifies the construction of the feed module, and eliminates the need for electric cables, while enabling efficient automatic movement and tool rotation for precise drilling operations.
Implementation Method 1
a first electric motor arranged in the drive unit housing; a spindle configured for connection to a machining tool, the spindle being rotatably mounted to the drive unit housing; a first transmission mechanism arranged in the drive unit housing for transmitting torque from the first electric motor to the spindle so as to allow the spindle to be rotated under the effect of the first electric motor
Implementation Method 2
a second electric motor arranged in the drive unit housing; a drive member rotatably mounted to the drive unit housing; and a second transmission mechanism arranged in the drive unit housing for transmitting torque from the second electric motor to the drive member so as to allow the drive member to be rotated under the effect of the second electric motor
Implementation Method 3
a feed gear wheel, which is rotatably mounted to the feed module housing and configured for engagement with a cog track arranged on the machine stand in parallel with said guide track in order to allow the feed module to move along the guide track by rotation of the feed gear wheel

AI summary
A machining assembly with a drive unit (10) detachably mountable to the feed module (30) and moveable along a guide track on a machine stand via the feed module. The feed module is provided with a feed gear wheel (33) configured for engagement with a cog track on the machine stand. An electric drive motor (12) for rotating a spindle (13) and an electric feed motor (16) for rotating the feed gear wheel are arranged in a housing (11) of the drive unit. The drive unit comprises a drive member, which is rotatable by the feed motor and which is operatively connectable to the feed gear wheel via a torque transmitting coupling mechanism (50) when the drive unit is mounted to the feed module so as to allow the feed gear wheel to be rotated under the effect of the feed motor when the drive unit is mounted to the feed module.
