Machine Tool Work Transfer Layout for Shorter Spindle Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools lack a structure that effectively reduces operation time during work reception and delivery between the main spindle and the work transferring mechanism.
Innovation Solution
The machine tool divides its internal space into machining and transferring areas using a shutter, allowing the work retainer to move to the vicinity of the main spindle during machining, and includes a main spindle moving mechanism to relocate the main spindle towards the transferring space, thereby shortening the distance and time required for work transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the work retainer moves to the vicinity of the main spindle during machining, then the operation time is reduced, but the machining space and transferring space need to be separated requiring a shutter
Solution Approach 1:
The internal space of the machine tool is divided into a machining space and a transferring space using a shutter. This segmentation allows the work retainer to preliminarily move to the vicinity of the main spindle during machining operations, enabling quick approach after machining completion and reducing overall operation time while maintaining safe separation between machining and transferring operations.
2Length of moving object
If the main spindle is relocated towards the transferring space, then the work transfer distance is reduced, but the machining space configuration becomes more complex
Solution Approach 1:
The main spindle is preliminarily relocated towards the transferring space before work transfer operations. This preliminary positioning reduces the distance the work retainer must travel to reach the main spindle, thereby shortening the work transfer time and improving overall operational efficiency.
3Speed
If the work retainer preliminarily moves during machining, then the approach time after machining is reduced, but the shutter mechanism is required
Solution Approach 1:
The work retainer performs preliminary movement to the vicinity of the main spindle during the machining process. By positioning the work retainer in advance, the approach time required after machining completion is significantly reduced, enabling faster work transfer operations.
Solution Approach 2:
A shutter mechanism divides the internal space into machining space and transferring space, allowing the work retainer to preliminarily move during machining without interfering with the machining process. This spatial segmentation enables parallel operations and reduces overall cycle time.

AI summary
A machine tool with work transferring mechanism 1 provided with a work transferring mechanism 8 which transfers a work 10 and receives/delivers the work 10 from/to a main spindle 3, wherein in the front-rear direction, the space inside the machine tool 1 is divided via a shutter 11 into a machining space 12 in which the main spindle 3 is arranged and a transferring space 13 in which the work transferring mechanism 8 transfers the work 10; the work transferring mechanism 8 is equipped with a work retainer 9 retaining the work 10, and a moving mechanism moving the work retainer 9; and while the work 10 attached to the main spindle 3 is being machined, the work retainer 9 is preliminarily moved by the moving mechanism to a vicinity of the main spindle 3 via the shutter 11.
