Description
Technical field
The present invention relates to reactor manufacture technology field more particularly to a kind of spider arm welding toolings.
Background technology
The important component that air reactor is shown in is carry the entrance of reactor weight and electric current and output unique
Component.The quality manufactured quality and directly affect entire reactor of spider arm.So manufacturing for spider arm is the key that reactor
One of project.
As shown in figure 4, spider arm is divided into bottom spider arm and top spider arm, by central shaft 11, linking arm 12 and absolutely
The compositions such as edge case loading board 13 and nameplate fixed plate.After these components are all processing, an entirety is formed by welding, and it is necessary
Ensure the angular error of spider arm in 0.5 below, and insulator exists by loading board with spider arm vertical error after welding
Within 0.1mm.So this process influences the quality of spider arm and entire reactor and its important.Due to previously used star
Shape arm welding jig there are it is certain the defects of, so it is imperative to develop a kind of novel process equipment.
As soon as spider arm welding first is completed on piece iron plate, the planarity requirements of iron plate are very high.Not only processing is tired
Difficulty, and there is also stress deformations for iron plate over time.This just impacts the quality of spider arm.
Furthermore spider arm is before welding, it is necessary to correctly be well placed central shaft and then be fixed with spider arm.Original determines
Position method is that the iron rod of several groups of relative clearances two-by-two is distributed in around iron plate central shaft.Spider arm is placed in the iron rod of positioning
Between put.Since the aluminium sheet wall thickness of manufacture spider arm is different, when using thin aluminum sheet, welding is just to be present with gap, this will most
It may cause the increase of the starframe error after welding or even error too big eventually and scrap.
The content of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and a kind of spider arm welding tooling is provided, improve star
Arm welding quality.
The present invention to achieve the above object, using following technical scheme：
A kind of spider arm welding tooling, it is characterised in that：Including bearing, cushion block and clamping plate, the centre bit of the bearing
Positioning sleeve has been installed, has been fixed on the bearing in cushion block ring week centered on the positioning sleeve, the Boards wall is in institute
It states on cushion block, the one side of the clamping plate is uniformly provided with two row, four row's screw hole, and the screw thread coordinates with hold-down bolt.
Preferably, auxiliary cushion block is correspondingly provided on the outside of the cushion block, the auxiliary cushion block is equipped with auxiliary clamping plate.
The beneficial effects of the invention are as follows:Compared with the prior art, in order to reduce foozle, novel welding is equipped in bearing
The mutually level cushion block in top is padded.Spider arm is just placed in above spacer pad, and so design is reduced to deep bid essence
The spider arm that the requirement of degree the is again contact with deep bid in the fabrication process reduces the possibility of spider arm deformation.It is padding simultaneously
The opposite side of block devises pressing plate, it is therefore an objective to which arm body is adjacent to spider arm with cushion block in the welding process, so as to ensure to greatest extent
Angle and the error of position.
Description of the drawings

Spider arm stress situation map when Fig. 2 is single support during this practicality is new；
Spider arm stress situation map when Fig. 3 is dual-gripper during this practicality is new；
Fig. 4 is the structure diagram of spider arm in the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings and the preferred embodiment specific embodiment that the present invention will be described in detail.
In the description of the present invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instructions such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer " is based on attached drawing institutes
The orientation or position relationship shown is for only for ease of the description present invention and simplifies description rather than instruction or imply signified dress
It puts or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that limit of the invention
System.
As shown in Figs. 1-3, a kind of spider arm welding tooling, including bearing 1, cushion block 2 and clamping plate 3, in the bearing
Heart position is equipped with positioning sleeve 4, is fixed on the bearing in cushion block ring week centered on the positioning sleeve.
Since the small-sized aluminium sheet height used with large-scale spider arm differs nearly 150%, so locating compression screw
Position is also different.In order to adapt to the aluminium sheet of different height, two row, four row's screw hole 5 is uniformly provided on clamping plate, is used
It is freely adjusted with the positioning compression bolt location on different aluminium rows.
In order to reduce foozle, novel welding equipment is padded in the mutually level cushion block in bearing top.Spider arm is just
Be placed in above spacer pad, so design reduce spider arm that the requirement to deep bid precision is again in the fabrication process with
The contact of deep bid reduces the possibility of spider arm deformation.Pressing plate is devised in the opposite side of cushion block, it is therefore an objective to which spider arm exists simultaneously
Arm body is adjacent to cushion block in welding process, so as to ensure angle and the error of position to greatest extent.
As shown in figure 4, the enlargement of manufacture reactor will be a trend now, so also increase lengthens spider arm therewith.
This results in a difficulty when welding spider arm, since spider arm cushion block position is compared by inner, when large-scale spider arm is put
The range difference at cushion block both ends is away from larger, and the spider arm being well placed is there are a torque, and under the action of this torque, spider arm exists
It is the displacement that vertical direction will occur to put, so as to cause to scrap.In order to reduce this deflection torque, installed additional on the outside of cushion block
One auxiliary cushion block 6 is to balance this torque, and the auxiliary cushion block is equipped with auxiliary clamping plate 7 so that spider arm normal docile
On cushion block.
Production design among, the size difference of spider arm is larger, the especially most important more difference of thickness model compared with
Greatly.According to this case, according to maximum 25mm limit of thickness during design, ensure positioning accuracy when using maximum gauge.
When using the spider arm of thinner thickness, on the face of spacer pad then first cushioning gasket is using spider arm to position, this
Just the problem of eliminating the workpiece positioning of different wall thickness.
When putting central shaft, since the size dimension of central shaft is all different, especially the size of location hole also it is each not
It is identical.In order to can be in place equally by dress for different central shafts, we specially manufacture for the central shaft in each aperture
As soon as positioning sleeve so uses special positioning sleeve to solve the orientation problem of central shaft when using different central shafts.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
