Description

Welding method of rotator and rotator

Technical Field

The invention relates to a welding method of a rotator and the rotator, and belongs to the technical field of welding.

Background

The rotator belongs to a rotator of a rotary assembly, a plurality of notches are required to be designed on the edge of the rotator, a block body with a smaller size is required to be welded on one side of each notch, and the block bodies are bilaterally symmetrical about the axial lead of a base of the rotator;

at present, a scribing is adopted, a welding line is scribed at a position of a block to be welded according to the distance between the axis of a base of a rotator, the welding line is the position of the block to be welded, the distance between the welding line and the axis is Y, as shown in figures 1 to 2, but the block is mainly held by a hand to be welded during welding, but the requirement on the position size Y is high, and during scribing and butt welding, the welded size error is large, the subsequent assembly of parts is affected, and the repair rate is high.

Disclosure of Invention

In order to solve the technical problem, the invention provides a welding method of a rotator and the rotator.

The invention is realized by the following technical scheme.

The invention provides a welding method of a rotator, which comprises the following steps:

step three, block welding: the block uses the radial tangential direction of pedestal to carry out quick location with the positioning section terminal surface as the locating surface and hugs closely, and spacing section and breach gomphosis are now restricted welding frock displacement and are obtained stably, then with the accurate definite welding of block in distance pedestal axial lead Y distance department.

Before step three, the method also comprises step two, the welding tool is matched: the limiting section at the upper part of the welding tool is embedded with the notch of the pedestal, and the end surface of the positioning section at the lower part of the welding tool forms a positioning surface for welding the block;

step one is further included before the step two, the welding tool is placed: and placing the welding tool on the platform surface at the lower part of the pedestal.

In the third step, the positioning section can stretch and retract to move the position.

The spinner formed by the welding method of the spinner comprises the following components: the pedestal is provided with an upper table top and a lower table top, and a plurality of gaps which are spaced and extend along the radial direction of the pedestal are arranged on the periphery of the pedestal;

and two ends of each block body are fixedly connected with the upper table top and the lower table top at a distance Y away from the axis line of the pedestal.

The block body is welded and fixed with the upper table-board and the lower table-board of the pedestal.

The bottom of the pedestal is fixedly connected with a plurality of spaced screws.

The number of the screws is at least three.

The screw is screwed and fixed with the bottom of the pedestal through threads.

And the screw is fixedly welded with the bottom of the pedestal.

The invention has the beneficial effects that: the block uses the radial tangential direction of pedestal to carry out quick location with the location section terminal surface as the locating surface and hugs closely, and spacing section and breach gomphosis restrict now that the welding frock displacement obtains stably, then with the accurate definite welding of block apart from pedestal axial lead Y apart from the department, has solved the great problem of dimensional error of marking off butt welding after the welding, has guaranteed the follow-up assembly of part, has reduced the rate of reprocessing of part.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1-4.

The invention discloses a welding method of a rotator, which comprises the following steps:

step one, placing a welding tool 4: placing a welding tool 4 on a platform surface at the lower part of the pedestal 1;

step two, the welding tool 4 is matched: the limiting section 41 at the upper part of the welding tool 4 is embedded with the notch 11 of the pedestal 1, and the end surface of the positioning section 42 at the lower part of the welding tool 4 forms a positioning surface for welding the block body 2;

step three, welding the block 2: block 2 is used 1 radial tangential direction of pedestal to carry out quick location with location section 42 terminal surface as the locating surface and hugs closely, and spacing section 41 obtains stably with the 4 displacements of the present restriction welding frock of 11 gomphosis of breach, then with the accurate definite welding of block 2 apart from 1 axial lead Y distance department of pedestal, has solved the great problem of dimensional error of marking off butt welding after the welding, has guaranteed the follow-up assembly of part, has reduced the rate of reprocessing of part.

The positioning section 42 is preferably telescopically adjustable, so that the position can be conveniently adjusted to different positions, and the universality of the welding tool 4 is improved.

The spinner formed by the welding method of the spinner comprises the following components: a pedestal 1 with an upper and a lower platforms, a plurality of gaps 11 which are spaced and extend along the radial direction of the pedestal 1 are arranged on the periphery of the pedestal 1;

the two ends of each block body 2 are fixedly connected with the upper table top and the lower table top at the position which is at the distance Y from the axis line of the pedestal 1.

The block body 2 is welded and fixed with the upper and lower table-boards of the pedestal 1.

A plurality of spaced screws 3 are fixedly connected to the bottom of the pedestal 1.
