Multipoint positioning auxiliary device

Abstract

The invention relates to a multipoint positioning auxiliary device. The multipoint positioning auxiliary device comprises a cylindrical base and a cylindrical indexing and positioning mechanism on the base. The indexing and positioning mechanism comprises an indexing disc and an aligning disc which can rotate relatively, the aligning disc is provided with a hemispherical positioning base, the positioning base is provided with a cross positioning groove penetrating through the hemisphere, a positioning wing groove is formed in the position, corresponding to the notch of the cross positioning groove, of the aligning disc, a spherical positioning groove is formed in the centre of sphere of the positioning base, a universal ball connected with a cylindrical scale pole is embedded in the spherical positioning groove, a positioning rod and a positioning wing are arranged between the universal ball and a scale pole body in sequence, the positioning rod is matched with the cross positioning groove, the section of the positioning rod is square, the positioning wing is matched with the positioning wing groove, and a positioning vernier which can slide along the scale pole body is arranged on the scale pole. The multipoint positioning auxiliary device has the advantages of being simple in structure, accurate in positioning, convenient to operate, store and carry and the like, multipoint positioning can be achieved conveniently and rapidly, operation is simplified, and working efficiency is improved.

Description

technical field [0001] The invention relates to a tool for point positioning, in particular to an auxiliary device for multi-point positioning. Background technique [0002] In the daily work of the power company, it is necessary to install various boxes and brackets. Usually, in the installation operation, it is necessary to mark the corresponding holes on the corresponding walls and other surfaces according to the distribution of the installation holes on the objects to be installed. The location of the installation hole can usually be determined by the following methods: 1) Manually place the object to be installed on the surface of the wall, and mark it on the surface of the wall according to the location of the installation hole, but some objects are large in size and heavy in weight , which makes the operation inconvenient. At the same time, the positions of the mounting holes on some objects are relatively hidden, and it is not easy to make comparison marks; 2) By mea...

[0002] In the daily work of the power company, it is necessary to install various boxes and brackets. Usually, in the installation operation, it is necessary to mark the corresponding holes on the corresponding walls and other surfaces according to the distribution of the installation holes on the objects to be installed. The location of the installation hole can usually be determined by the following methods: 1) Manually place the object to be installed on the surface of the wall, and mark it on the surface of the wall according to the location of the installation hole, but some objects are large in size and heavy in weight , which makes the operation inconvenient. At the same time, the positions of the mounting holes on some objects are relatively hidden, and it is not easy to make comparison marks; 2) By measuring the distance between the mounting holes, use a scale to mark the surface of the wall, but this method will lead to installation problems. The operation is cumbersome, and the installation is tilted and unsightly; 3) Auxiliary devices such as punching templates are used for auxiliary installation. The existing installation hole positioning auxiliary devices are basically composed of several scales, such as the Chinese patent application CN201310646287.0 A meter box installation auxiliary tool and its use method, Chinese patent application CN201310427075.3 A meter box installation locator, etc. These auxiliary tools have the following disadvantages: they are large in size and cannot be stored, making these tools not easy to carry; It can only locate the installation holes with relatively regular position distribution, such as four-hole distribution in square or rectangular distribution; the number of positioning holes is limited, and only a small number of holes can be positioned; it cannot be positioned on non-planar wall surfaces , these auxiliary tools cannot work on relatively narrow surfaces
