Abstract

The invention belongs to the technical field of lubricating and maintaining guide rails of machine tools, and specifically relates to a dovetail guide rail lubricating and maintaining device for machining equipment, which includes an operating rod, a lubricating block, a telescopic unit, a pressurizing unit and a turntable; the end of the operating rod is provided with a guide rod ; Both ends of the guide rod are slidingly connected to a turntable; one side of the turntable is fixedly connected to the lubricating block; the other side of the turntable is screwed to the telescopic unit; the telescopic unit is rotatably installed inside the operating rod; One side, and fixedly connected to the lubricating block through the pipeline. Rotate the rotating rod inside the operating rod, snap the two lubricating blocks into the dovetail groove, push the tool along the direction of the dovetail groove, the balls set on the lubricating block will spread the grease evenly on the surface that needs to be lubricated. The invention can conform to the shape of the dovetail groove for lubricating operation, improves the uniformity of lubrication, reduces the relative wear of the dovetail guide rail and the dovetail groove, and increases the service life of the machine tool.

Description

technical field

[0001] The invention belongs to the technical field of lubricating and maintaining machine tool guide rails, in particular to a dovetail guide rail lubricating and maintaining device for machining equipment. Background technique

[0002] Guide rail: A groove or ridge made of metal or other materials that can bear, fix, guide a moving device or equipment and reduce its friction. Longitudinal grooves or ridges on the surface of rails for guiding and fixing machine parts, special equipment, instruments, etc. Guide rails, also known as slide rails, linear guide rails, and linear slide rails, are used in linear reciprocating motion applications. They have a higher rated load than linear bearings, and can bear a certain torque at the same time. They can achieve high-precision linear motion under high load conditions. .

[0003] The dovetail guide rail is a kind of guide rail on the machine tool, and the screw drives the table to slide on the guide rail. The cros...

Embodiment approach

[0026] As an embodiment of the present invention, the turntable 5 includes a left connecting plate 51, a right connecting plate 52, a rotating shaft 53 and a rubber wheel 54; the left connecting plate 51 is screwed to one side of the telescopic unit 3 and is slidably connected to Guide rod 11; the right connecting plate 52 is fixedly installed on one side of the slider 2; the rotating shaft 53 is connected between the left connecting plate 51 and the right connecting plate 52; a rubber wheel 54 is fixedly installed on the outer periphery of the rotating shaft 53; The inside of the rubber wheel 54 is provided with a cavity, and lubricating grease is injected into the cavity. The middle part of the rubber wheel 54 is provided with a micro hole 55 inclined towards the end of the rotating shaft 53. When the tool is pushed, the rubber wheel 54 rotates. Grease is extruded to the rotating shaft 53 to improve the flexibility of the device.

[0027] As an embodiment of the present inve...
