Abstract

PURPOSE:To obtain the titled equipment with improved efficiency by calculating correction of the quantity of fine adjustment of a welding condition and providing a condition correction means to store the result to omit the time to set the welding condition again by a welding condition setter. CONSTITUTION:After the welding is finished, a storage command switch 21 is pushed to correct the stored welding condition. A CPU 5 receives this command and begins working to read in order the quantity of fine adjustment of a fine adjustment dial 1. An A/D converter 20 A/D converts each adjustment quantity in order of a welding current, the welding voltage and the welding speed and the CUP 5 taken in these as the fine adjustment data through an I/O 7. The CPU 5 then taken out the data of a welding condition group designated by a designation switch 2 in order by a RAM 12 and calculates the correction by the fine adjustment data and stores the result again in the RAM 12. Accordingly, the fine adjustment is converted and the welding condition is corrected and the time to set the welding condition again by the welding condition setter is omitted and the extremely highly efficient equipment is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial f'November Edition] The present invention relates to a self-visit welding device having various welding conditions V constant return capability and output control function.

[Conventional technology]

In general, in the case of arc welding, the output is often controlled based on various welding conditions.The conditions to be controlled are welding current and welding voltage.

The main factors are welding speed, etc., but v! When it comes to a device with a coarse +s function, the oscillation width and other characteristics often vary.

Conventionally, there has been a device of this type as shown in Figure 2.

In the figure, (1) is means for fine-tuning welding conditions.

(2) is a welding condition group designation switch, and C is a setting device for IF# moxibustion condition. The fine adjustment means (1) and the designation switch (2) are located in the crushing box (4).

In addition, (5) is the APD (central processing unit) that is the center of control.
, (6), and (7) are interface circuits (hereinafter referred to as 10) that connect C20 (5) to external circuits.8Furthermore, (8) is a welding power source, and (9) is a welding torch (□□□
(not shown), etc., and each is connected to the I/O (7) through amplifier circuits αQ and αυ. In addition, the fine adjustment means (1) is the amplifier times vP hitting, Q
It is grounded at ℃. Also, 4 is RAM, OFσ(
5) is directly connected to store welding conditions, etc. α) stores the control program in ROM and b7+.

Next, the operation will be explained.

The bath contact conditions are set using the condition setting device (3).

The set conditions are stored in the RAM (2) under the control of C20 (5) through the process/○ (6). Next, the welding condition group, that is, the bus number, is designated by the designation switch (2).

After preparing for welding as described above and looking at the start switch (not shown), COσ (5) takes out the welding condition group specified by the designation switch (2) from RAM (L15) and calculates for output. After that, output control is started for the amplifier sections +lQ and (6) through the I/O (7).

Note that the output control sequence control is stored in the ROM, and the C20(5) follows this. Furthermore, while checking the welding state, the operator can adjust the welding conditions to a desired level using the r/image adjustment dial (1). Of the fine adjustment dials (1), welding current stagnation and welding pressure 1 are connected to Ampro 28aO, and melting speed is connected to Ampro 1 σ°C, which is connected to C20 (5
), that is, the output value of the stored conditions.

It is a comparative increase @. This results in a welding power source (8).

As for the output control value for the welding head (9), the value adjusted by wL adjustment diamond /L/(1) becomes the final output side control value.

[Problem that the invention seeks to solve]

Since conventional automatic welding equipment is rioted as described above, it is not possible to leave the fine adjustment 1 during welding as a welding condition in some form, and after welding is completed, the fine adjustment is converted into welding conditions. There have been problems such as the need to correct the condition and set it again using the condition setting device (3).

This invention was made in order to solve the above-mentioned problems, and the description for f1! The purpose is to obtain an automatic welding device that can perform correction instantly.

[Means for resolving related points]

The automatic welding device according to the present invention) is suitable for the set welding conditions group! It is equipped with a condition correction means for performing correction calculation and storage for the data of the welding condition group based on the stage I:f and its adjustment It.

[Effect]

The condition correction means in this invention calculates fine adjustment ILK correction for the stored welding conditions, and corrects the stored welding conditions as a result.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. 1st
In the figure, parts having the same invasive ability as in FIG. 2 are designated by the same reference numerals, and their explanation will be omitted.

In the figure, [Co., Ltd.] is connected to the *A adjustment diamond A/(1) with an A, /D converter, and /O(7).

Also, it is a memory command switch for storing corrected welding conditions.

(2) is a fine adjustment diamond) v(1), a welding condition 1kf designation switch (2), a memory command switch t2n, and an operation box that is installed together. The threat is conditional correction f-stage, but this means is different from each other) 1 publication? It also has A+a functions, such as sequence control functions.

Next, 1171 works will be explained.

Setting of welding conditions and designation of welding condition groups are the same as in the conventional example. Further, the operation in which one operator starts welding and finely adjusts the conditions is the same as in the conventional example.

After welding is completed, press the memory command switch (c) to correct the memorized bath contact conditions.

C0U (5) receives this command and fine-tunes the diamond /I/(

The converter ■ has 1 welding voltage and 1 welding speed, respectively.
14 constant quantity, that is, each voltage land is used as A, /D, C20
(5) imports this as *m complete data through /O(7).

C20 (5) then sequentially retrieves the data of the welding condition group specified by the designation switch (2) from RAM (13), performs correction calculations using the aforementioned wL adjustment data, and stores the results in RAM Mυ again. .

Since all of the above operations are performed by C20(5), the operation time is only a few μs.

In the above example, the correction calculation was performed at the time when the command switch was manually turned to 1.

This may be synchronized with some timing (for example, a welding end signal), and corrected and stored in the automatic adjustment.

[Effects of the Invention] As described above, according to the present invention, the amount of fine adjustment of welding conditions is instantaneously converted into a correction meter and stored, so that the amount of fine adjustment can be changed and the welding conditions can be corrected. .

It is possible to save the amount of balls that must be set and removed again using a welding condition setting device, and it is possible to obtain an extremely efficient self-121fPf welding device.
