Sliding Table Lubrication Path Without Cover Plate Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-mover sliding table modules require cumbersome maintenance processes, including removal of protective cover plates and sealing members to lubricate sliding blocks, which can lead to improper lubrication and damage to other components.
Innovation Solution
The sliding table device features a design with oil inlets on sliding blocks and a lubricant-feeding fitting integrated into the sliding seat, allowing lubrication without removing the cover plate, where lubricant is injected through an insertion hole in the cover plate's outer surface, flowing through guiding and connecting passages to reach the oil inlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protective cover plate and sealing members are removed to lubricate the sliding blocks, then the oil inlet can be accessed for lubrication, but the maintenance process becomes troublesome and lubricating oil may be sprayed on other components
Solution Approach 1:
The patent extracts the oil inlet from the sliding block and relocates it to the cover plate, allowing lubrication to be performed through the cover plate's oil inlet without removing the cover plate or sealing members. This resolves the contradiction by enabling easy access to the lubrication point while maintaining the protective cover plate in place.
Solution Approach 2:
The patent introduces an intermediary oil inlet in the cover plate that serves as a mediator between the external lubrication source and the internal sliding block. Lubricating oil is injected through this intermediary inlet, flows through the sealing member and guide passage to reach the sliding block, thus enabling lubrication without direct exposure of the sliding block's original oil inlet.
2Ease of operation
If the sealing members are removed to access the oil inlet, then lubrication can be performed, but foreign objects or foreign matter may enter the system
Solution Approach 1:
The patent extracts the lubrication function from the sealed sliding block interior and relocates it to the cover plate area. The oil inlet is moved to the cover plate while maintaining the sealing member's integrity, allowing lubrication without compromising the sealing system.
Solution Approach 2:
The cover plate oil inlet acts as an intermediary that enables lubrication while the sealing member remains in place to prevent foreign objects from entering. The lubrication path is established through the sealing member without requiring its removal, thus maintaining both ease of lubrication and protection against contamination.
3Ease of operation
If the oil gun is not properly aligned with the oil inlet, then lubricating oil may be sprayed on other components, but proper alignment is difficult when the oil inlet is exposed
Solution Approach 1:
The patent extracts the oil inlet from the sliding block and relocates it to the cover plate, where it can be more easily accessed and aligned. The oil inlet in the cover plate is positioned in a location that facilitates proper alignment with the oil gun, reducing the risk of misalignment and spray contamination.
Solution Approach 2:
The cover plate oil inlet serves as an intermediary target for lubrication, providing a larger, more accessible target area for oil gun alignment compared to the original exposed oil inlet on the sliding block. This intermediary location improves alignment precision while maintaining ease of lubrication.

AI summary
A sliding table device includes a base unit, a sliding unit and a cover plate. The sliding unit includes two rails, two sliding blocks disposed respectively and slidably on the rails and each having an oil inlet, and a sliding seat mounted co-movably on the sliding blocks. The sliding seat includes a main portion having a flow passage and an insertion hole that interconnects the flow passage and external environment, two fixed portions mounted respectively to the sliding blocks and each having a connecting passage that communicates with the flow passage, and two guiding portions formed respectively on the fixed portions and each having a guiding passage that communicates with the corresponding connecting passage and the corresponding oil inlet. The cover plate covers a portion of the main portion, and the insertion hole is not covered by the cover plate.
