Description

Metal sleeve sand blasting machine containing fixing tool

Technical Field

The utility model belongs to the technical field of metal surface treatment, specificly belong to metal surface sand blasting field.

Background

A metal casing sand blasting machine is a sand blasting machine aiming at metal casings. When the surface of the metal sleeve is subjected to sand blasting treatment, the metal sleeve needs to be fixed on a rotating disc of a sand blasting machine, and a binding tool capable of stretching up and down needs to be installed on the rotating disc of the sand blasting machine; when the fixing is performed, the knot is inserted into the inner hole of the metal sleeve for fixing. The currently used tie comprises a first part and a second part, wherein the outer part of the first part of the tie is made of wear-resistant rubber materials, and the inner part of the first part of the tie is provided with a hollow aluminum alloy shaft sleeve; the outer part of the second part of the knot tool is made of wear-resistant rubber materials, the inner part of the second part of the knot tool is a solid aluminum alloy shaft and extends out of the rubber sleeve, and when the knot tool is used, the aluminum alloy shaft of the second part of the knot tool is inserted into the aluminum alloy shaft sleeve of the first part of the knot tool and then fixed by bolts.

In the prior art, the rubber material on the outer side of the first part of the knot is fixed with the hollow aluminum alloy shaft sleeve on the inner side by bolts, and the bolts are exposed on the outer side of the rubber material, so that the bolts are seriously abraded and difficult to replace during sand blasting; the first part of the existing knot tool adopts a hollow aluminum alloy shaft sleeve, so that the knot tool is inconvenient to install, easy to wear and high in cost; and the second part of the existing knot is sleeved in the metal sleeve and is circular, so that the conical inner hole of the metal sleeve cannot be cleaned during sand blasting.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pair of metal casing sand blasting machine who contains fixed knot utensil to solve the problem that proposes among the above-mentioned background art.

To the above-mentioned problem that current metal casing sand blasting machine exists, the utility model discloses a following technical scheme: the first part of the knot tool adopts a hollow rubber cement tool without an aluminum alloy shaft sleeve, and the upper part of the second part of the knot tool still adopts a solid aluminum alloy shaft neck but the lower part of the second part of the knot tool is additionally provided with an inverted cone-shaped contact surface. The upper part and the lower part of the knot adopt matching connection, and exposed bolt connection is cancelled.

Furthermore, the first part of the structure of the sand blasting machine is fixedly connected with the telescopic shaft, and the bolt penetrates through the gasket with the inner diameter smaller than the diameter of the telescopic shaft and the threaded hole at the lower end of the telescopic shaft to complete the fixed connection.

Through adopting above-mentioned technical scheme, the completion knot that can be swift possesses the first portion and the fixed of telescopic shaft, avoids inconvenient because of the installation that uses the aluminum alloy axle sleeve to lead to, easy wearing and tearing, problem with high costs.

Furthermore, the second part of the knot is made of wear-resistant rubber materials on the outer portion, and a solid aluminum alloy shaft extends out of the rubber sleeve on the inner portion. The aluminum alloy shaft neck protruding from the second part of the knot tool is slightly larger than the inner diameter of the lower part of the first part of the knot tool, and the first part of the knot tool is made of rubber materials, so that the aluminum alloy shaft neck can be directly plugged into the inner diameter of the first part of the knot tool to realize interference fit and complete fixed connection.

By adopting the technical scheme, the fixed connection can be directly completed for the first part of the knot tool and the second part of the knot tool, and the problems that bolts are seriously abraded and difficult to replace due to the use of bolt connection are avoided.

Furthermore, a reverse conical contact surface capable of being processed is additionally arranged below the second part of the sand blasting machine. Because the outer material of the second part of the knot is wear-resistant rubber, the conical surface of the knot at the lower part can be processed according to the angle of the metal sleeve, and the inner surface of the metal sleeve can be cleaned when the sand blasting rotation is carried out.

Through adopting above-mentioned technical scheme, the staff of being convenient for when the sand blasting machine sandblast is rotatory cleans metal sleeve hole internal surface, avoids leading to the unable cleanness of metal sleeve internal surface because of using the circular shape knot utensil contact surface.

Compared with the prior art, this kind of metal casing sand blasting machine who contains knot utensil possesses following beneficial effect: 1. the utility model has the advantages that the direct interference fit connection between the first part and the second part of the knot tool avoids the problems of serious abrasion and difficult replacement of the bolt caused by the use of bolt connection, and is convenient to install; 2. the rubber knot without the aluminum alloy shaft sleeve is adopted in the first part of the knot, so that the cost is reduced, and the problems of inconvenient installation, easy abrasion and high cost caused by the use of the aluminum alloy shaft sleeve are solved; 3. the utility model discloses a knot utensil second part below increases workable back taper contact surface, and the staff of being convenient for cleans metal sleeve hole internal surface when the sand blasting machine sandblast is rotatory, avoids because of using the circular shape knot utensil contact surface, leads to the contact surface of knot utensil and metal sleeve internal surface unable cleanness.
