3 Terminology
3.1 Horizontal stroke L
Machine The maximum distance the welding gun on the head moves along the axis of the cross arm. 3.2 Vertical stroke H
The maximum distance the cross arm can lift along the column.
3.3 Lifting speed m
The speed at which the cross arm rises and falls along the column.
3.4 ??Idle speed VF
The moving speed of the column or cross arm or machine head during non-welding time. 4 Type classification
4.1 In addition to the two parts of the upright column and the transverse arm, the operating machine should also be equipped with a welding head connection slide, a welding wire bracket, etc. on the transverse arm. Flux recovery devices and layoff platforms can also be set up according to user needs. 4.2 According to whether the column can be moved, it is divided into two types: fixed type and movable type. 4.3 According to whether the horizontal arm extension length can be adjusted, it is divided into two types: fixed horizontal arm type and adjustable horizontal arm type. 4.4 According to whether the cross arm can rotate around the axis of the column, it is divided into two types: rotatable and non-rotatable. 5 model indication

Name code (Chinese Pinyin letters)
5.2 "HC" is the name code of the welding operator, which is the abbreviation of the Chinese Pinyin of "welding operator". 5.3 "X," is the value of the horizontal stroke L of the operating machine, the unit is mm. 5.4"X, \ is the value of the vertical stroke H of the operating machine, the unit is mm. 5.5" "Y" represents the movable type, \G" represents the fixed type. 5.6 "X," is the cross arm adjustment code, expressed in Arabic numerals. The cross arm adjustable type is "1", and the cross arm fixed type is "2". 5.7 "X," is the rotation code of the cross arm, expressed in Arabic numerals. The cross arm can be rotated as "1", and the cross arm cannot be rotated as "2". 5.8 Example
HCJ1250×1000Y-12 represents a welding manipulator with a horizontal stroke of 1250mm, a vertical stroke of 1000mm, a movable column, and an adjustable cross arm but cannot be rotated.
Basic parameters
6
6.1 The moving speed of the cross arm or machine head should ensure that the welding speed range is 100~1500mm/min. On the premise of meeting the requirements of this standard, the welding speed range is allowed to be expanded. 6.2 The maximum idle speed of the transverse hip or nose should not be less than 2000mm/min. 6.3 The cross-arm rotation angle of the cross-arm rotary manipulator should not be less than 270°. 6.4 Other parameters of the operating machine are shown in Table 1 and its type diagram (Figure 1). On the premise of meeting the requirements of this standard, the horizontal stroke and vertical stroke values ??are allowed to be appropriately changed from the values ??in the table according to the user's requirements.

1 machine head + 2-cross arm: 3-column
7.1 Whether the welding process is realized by the movement of the cross arm or the machine head, it should achieve stepless speed, and When the network voltage fluctuates ±10%, the welding speed fluctuation shall not exceed ±3%.
7.2 The rotation of the cross arm should be able to control the rotation angle, and there should be a rotation angle indication mark. 7.3 The lifting, telescopic, rotating and column movement of the cross arm should be positioned by locking mechanisms. 7.4 When the cross arm extends to its maximum, the downward slope of its end point in the vertical plane after loading shall not exceed 2 mm. If this requirement cannot be met, the machine head should be equipped with a height tracking device
7.5 When the cross arm is extended to its maximum and locked, its endpoint swing in the horizontal plane shall not be greater than ±0.5mm. 7.6 The movement of the cross arm and the machine head should be smooth, without crawling or shaking. 8 Others
8.1 The electrical equipment of the operating machine shall comply with the relevant provisions of ZBK90001. 8.2 The structure of the machine head should be convenient for installing welding devices such as the wire feeding mechanism. The structural form can also be determined by the manufacturer and the user through consultation. 83 The rated load that the cross arm can withstand when it reaches its maximum extension, as well as other functions of the operating machine, should be described in the instruction manual. 424
Inspection items and acceptance rules
