A spraying equipment for the inner wall of a circular pipe

Abstract

The invention relates to spraying equipment for an inner wall of a circular tube. The spraying equipment mainly comprises a base, a mounting cylinder, an inner-frame support and an outer-frame support, wherein a subplate is arranged in the mounting cylinder; the upper end of the mounting cylinder is provided with an inner rail; the upper part of the mounting cylinder is provided with a positioning cover, and the lower end of the positioning cover is provided with a fixture block; a spray gun is arranged above the positioning cover, and is connected with a lateral extension frame; the inner side of the inner-frame support is provided with a sliding rail fame, and the sliding rail fame is provided with a falling gap; two ends of the falling gap are provided with a shaft and a limiting groove, and the shaft is connected with a brake plate; the shaft is connected with gears; an idle wheel is arranged between every two gears; the outer-frame support is provided with a slide; a small lead ball is arranged in the slide and is connected with an L connecting rod, and the upper end of the L connecting rod is connected with an N connecting rod welded with the lateral extension frame. The spraying equipment has the advantages that based on automatically achieving the function of spraying the inner wall of the circular tube with high quality, the operation is convenient, and the phenomena that power wires and nanometer material supply lines knot and are tightly twisted can be effectively prevented.

Description

technical field [0001] The invention relates to the field of supersonic spraying, in particular to a spraying equipment for the inner wall of a circular pipe. Background technique [0002] Generally speaking, for some high-precision instruments or devices, supersonic spraying of nanomaterials is often required on the surface, but some devices are inconvenient to spray due to shape problems, especially the inner wall of the round tube, manual spraying is not only The operation is very inconvenient, and the quality of spraying is also very low. [0003] For the above problems, some people have also come up with the idea of ​​controlling the spray gun in an automated way to spray the inner wall of the circular tube. The specific method is to use the corresponding power components and transmission equipment to synchronously control the spray gun to rotate and feed. The movement like spring stroke, the spraying in this way not only has good spraying quality, but also has a high ...

[0003] For the above problems, some people have also come up with the idea of ​​controlling the spray gun in an automated way to spray the inner wall of the circular tube. The specific method is to use the corresponding power components and transmission equipment to synchronously control the spray gun to rotate and feed. The movement like spring stroke, the spraying in this way not only has good spraying quality, but also has a high degree of automation and is very convenient to control, but the problem is that although the spray gun can complete such a movement, the power line and nanomaterial supply line connected to the back end of the spray gun are in this way. Under the action of repeated unidirectional rotation, the power line and nanomaterial supply line will often be knotted and hanged, which will lead to greater safety hazards such as spray gun failure or line short circuit.
