Ram Drop Compensation via Elastic Counter-Guides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Milling machines face precision errors due to deviations in the ram and tool head caused by gravitational effects during transverse movement, which are difficult to correct using numerical control systems, especially as the tool moves away from the machine column.
Innovation Solution
A compensation system using bending counter-guides, comprising perforated plates with notches for elastic deformation, linked with sliding blocks and a continuous measuring control system to lift the ram and maintain a perfect horizontal position, ensuring precise transverse and vertical alignment of the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If numerical control systems are used to correct ram deviation, then positioning precision can be improved, but the correction becomes more complicated and less effective as the tool moves away from the machine column
Solution Approach 1:
The patent replaces complex numerical control programming with a mechanical compensation system using elastic counter-guides that automatically correct ram deviation through elastic deformation, eliminating the need for complicated CNC correction algorithms
Solution Approach 2:
The elastic counter-guides automatically compensate for ram drop through their inherent elastic properties during transverse movement, providing self-correcting functionality without requiring external control systems or programming
2Manufacturing precision
If rotational elements or pulley systems are used to correct ram drop, then the ram horizontal position can be maintained, but the device complexity increases
Solution Approach 1:
The patent changes the physical state of the counter-guides from rigid to elastic, allowing them to deform and absorb the ram drop through elastic bending rather than requiring complex rotational or pulley mechanisms
Solution Approach 2:
The patent uses elastic counter-guides that function as flexible structural elements, allowing controlled deformation to compensate for ram drop without the complexity of rigid rotational or pulley systems
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
The system effectively corrects ram drop errors by continuously monitoring and adjusting the ram's position, ensuring a perfectly horizontal ram exit and vertical tool arrangement, improving machining precision and reducing equipment wear.
Implementation Method 1
The concept distinguishing the system object of the invention from the systems based on rotational elements described above is the elastic bending deformation of the counter-guide plates which can be provided with notches in their side profiles to favor bending precisely at said points.
Implementation Method 2
A continuous measuring control controls the drop of the ram by means of checking its transverse movement and the vertical position of its head, sending a signal to an operating assembly acting on the counter-guide plates

AI summary
The present invention relates to a compensation system for compensating for the drop of the ram in a machine tool, comprising a vertical translation carriage (1) incorporating the application ram, at least one and preferably two perforated plates (2) being arranged on said carriage (1), on each of which there is incorporated a fixed sliding block (3) and movable sliding blocks (4), which blocks are linked with a guide for the transverse movement of the ram, such that the drop of the ram is compensated for by means of the controlled bending of the plates (2).
