RU2463154C1 - Angular adapter - Google Patents

Abstract

FIELD: process engineering.

SUBSTANCE: invention relates to machine building, namely, to working tool holders made up of angular adapters to be fitted on rotary drive. Proposed adapter comprises casing, handle and body accommodating two shafts with bevel gears fitted thereon. Section of one of said shafts has tetrahedron to receive wrench and thread whereon screwed are discs or nuts to lock grinding wheel of saw blade. Another shaft is to be coupled with rotary drive.

EFFECT: compact and simple design.

Description

The sample product proposed in the drawings is called the "corner nozzle." This product allows, using rotating shafts (or axes), to replace the missing special tool (such as an angle grinder (vernacularly “grinder”), a circular saw, socket wrenches, drill), saving time and money, and sometimes even replacing tools that are not in production. The product can be used in automobile transport, housing and communal services, the Ministry of Emergencies and other industries where the use of a special tool is necessary.

The closest analogue of the claimed product is an invention registered in the FIPS databases under No. GB 2449490 A, 11/26/2008

The product consists (figure 1, top view) of the housing 1, in which there are shafts 3A and 3B with bevel gears fixed to them. For ease of assembly, the housing should be prefabricated, of two halves fastened together by means of bolts through the eyes 5 (the shape of the eyes may be different). The shafts 3A and 3B, during rotation, rotate in the bearings 2, and the inner diameter of the bearing race and the outer diameter of the shafts must match.

A thread 10 is cut on the rear of the shaft 3B, onto which two plates 12 are wound (ordinary nuts can be used instead of the plates), locked with a nut 9, the rear of the shaft 11 is faceted under a tetrahedron. A casing 8 is fixed to the eyes 5 of the housing 1 (figure 1) through the lugs 16 that are in place, which during operation protects the user from sawdust, sparks and scraps of material (figure 4, view from the front of the casing).

Also, the handle 4 is attached to the eye 5 of the housing 1 with the help of a bolt 15 (figure 2, side view, without casing).

On the back of the shaft 3A, a shank is fastened with bolts 7 and nuts 13, consisting of two inner linings 6 and two outer linings 14 (Figure 3, A is a side view, B is an end view), the shank is used if it is impossible to fix the shaft 3A otherwise with a source of rotational motion.

We will consider the operation of the device using an example of a drill as a source of rotational motion.

The back of the shaft 3A (in this case, without a shank) is fixed in the drill chuck. Between the plates 12 we fix the cutting emery wheel used in the work of cutting metal or stone (or a circular saw blade, or we put a socket wrench on the tetrahedron 11). When the drill cartridge rotates, the shaft 3A rotates, rotating the gear of the shaft shaft 3B with the necessary equipment installed on it by the user, the product is ready for use.

If necessary, use the shaft (or axis) as the source of rotational motion on the rear of the shaft 3A and put the shank on the existing axis (or shaft) and tighten with bolts 7 and nuts 13.

Claims (1)

An angular nozzle for mounting on a source of rotational motion, designed to install an emery wheel or a circular saw blade or a socket wrench on it, characterized in that it comprises a housing with eyes, in which there are two shafts with bevel gears rigidly fixed to them, and the casing and the handle fixed in the eyes of the housing, while on the part of one of the said shafts a tetrahedron is made for installing a socket wrench and a thread is cut on which plates or nuts are screwed ki for fixing between them an emery wheel or a blade of a circulation saw, and another specified shaft is intended for fastening with a source of rotational motion.
