Equipment for spraying lubricating grease on inner wall of pipe

Abstract

The invention discloses equipment for spraying lubricating grease on the inner wall of a pipe. The equipment comprises a rack, and further comprises a metal pipe X-direction electric clamping device, a metal pipe Y-direction electric clamping device, an electric lifting device and a spraying device, wherein the metal pipe X-direction electric clamping device and the metal pipe Y-direction electric clamping device are arranged on the rack, and the electric lifting device and the spraying device are arranged on the rack; the inner end of a supporting base of the spraying device is connected with the electric lifting device and is driven, and the outer end of the supporting base is provided with the spraying device communicating with a pressure lubricating grease conveying device and a grease atomization device; and the axis of a spraying pipe of the spraying device and the axis of a spray head which is arranged at the top of the spraying device and used for spraying the lubricating grease on the inner wall of the metal pipe are located on the same plumb line with the axis of the clamped metal pipe, and the spray head enters the metal pipe from the bottom end of the clamped metal pipe. The equipment further comprises a master controller, and the X-direction electric clamping device, the Y-direction electric clamping device, the electric lifting device, the pressure lubricating grease conveying device and the grease atomization device are all electrically connected with the master controller. The lubricating grease can be sprayed on the inner wall of the metal pipe of an outer pipe of a table leg of an electric lifting table, uniformity is achieved, and the spraying efficiency is high.

Description

technical field [0001] The invention relates to the technical field of pipe lubrication and rust prevention, in particular to a device for spraying lubricating grease on the inner wall of a pipe. Background technique [0002] In many occasions, inner and outer sleeves are required. For example, the legs of electric lift tables in intelligent office equipment adopt inner and outer sleeve structures, and generally use rectangular inner and outer sleeves of metal materials. The ball screw pair drives the inner casing up and down in the outer casing to drive the desktop up and down. In order to ensure the flexibility and service life of the sliding of the inner and outer sleeves, it is necessary to apply grease to the inner wall of the outer sleeve to lubricate the inner and outer sleeves and prevent rust. Grease generally uses calcium-based grease, commonly known as butter, of course, lithium-based grease or lithium-complex grease is also used. [0003] The traditional lubric...

Problems solved by technology

[0003] The traditional lubricating grease on the inner wall of the smearing tube is applied manually with a rod-shaped tool that extends into the tube, which has low efficiency and uneven application. The grease is missing or too thin to have lubricating and anti-rust effects, and too much grease is squeezed out and wasted. and pollute

[0004] In recent years, there are records on the Chinese patent website that the inner wall of the tube is sprayed with grease, but it cannot be used for the outer tube of the table leg of the electric lift table, such as a height or length of about 1 meter, and a rectangle such as a rectangle whose long side does not exceed 10 cm metal pipe

In addition, the grease delivery device of the prior art generally only relies on the pump supply, and its continuity and reliability are not enough. How to ensure smooth and continuous supply of the grease required for atomized spraying to the nozzle, the prior art does not provide a solution Strong technical solution
