In people's eyes, welding positioner may be considered as an insignificant product. However, internationally, there are more than 100 series, including products with various functions. There are common types in technology; With or without gap drive servo control type; The rated load range of the product reaches 0. 1kn ~ 18000kn. It can be said that the welding positioner is a product with many varieties, high technical level, small, medium and large development.
Generally speaking, most manufacturers of welding equipment such as welding manipulator, roller frame and welding system produce welding positioner; Most welding robot manufacturers produce robot welding locators. However, there are very few enterprises taking welding positioner as the leading product. Severt company in Germany and Aroson company in the United States are typical enterprises that produce welding positioner. CLOOS in Germany, igm in Austria, Panasonic Robotics in Japan, etc. They all produce welding positioner with servo control and robot matching. The following only introduces the type of displacement machine, the first main parameter and so on. The company mainly produces 8 kinds of products, 7 of which are welding positioner. According to their functions, each type of welding positioner includes four products: basic type, speed regulation type, numerical control program control type and robot matching type.

[6] [6] S60: including S60. 1 and S62 product series. Namely: ① tilt-rotation (0 ~ 90); (2) Tilt-rotate (90).
(7) ⑺S70: It includes S70. 1, 2 and 3 product series. Namely: ① Vertical multi-station 4-axis (4-DOF) single rotation; ② Vertical multi-station 2× tilting type (6 degrees of freedom); ③ Vertical 4-station vertical 4-axis single rotation.
The above ***33 product types, each of which includes products with the above four functions, are equivalent to 132 product series. The rated load is 100 DN ~ 10 KDN. The welding equipment produced by Aroson company in the United States includes welding positioner, manipulator, roller frame and so on. , is the best in the world. The welding positioner produced by our company mainly includes tilting, tilting and lifting, double-seat and double-rotating, double-seat and single-rotating and double-seat and single-rotating lifting. Its carrying capacity ranges from 1 1 kg to 18 10 ton.
(1) Manual double return type. Series C, model C 1000, 2000, 4000. Load 25 pounds to 4000 pounds.
(2) Small tilting rotary type. LD series, models LD 60N, LD 150N, LD 300N, with carrying capacity of 132lbs, LD 330lbs and LD 660lbs respectively.
(3) Tilting type, inclination angle 135. D, HD series, bearing capacity of 3 14 lbs ~ 70000 lbs.
(4) Tilt-rotate (pin changing) positioning lifting type, tilt angle 135. AB series (30~ AB 1200) has a bearing capacity of 4,300 lbs ~120,000 lbs.
5] Tilting-rotating (rack and pinion) stepless lifting type, GE series, tilting angle 135, model (GE25~GE3500, bearing 2500 ~ 350000 pounds.

(7) Two-seat double rotary type, DCG series, with the maximum product bearing capacity of 500 tons.
Being single rotary HTS series, HTS5, 9, 12, 20, 32, 40, 50, 60, 90, 160, 240, bearing 500-240,000 pounds.
⑼ Single rotation (rack and pinion) lifting type, HTS- GE series, HTS5 GE and HTS 240GE, with a bearing capacity of 500-240,000 lbs. It involves the user's concept of equipment and equipment, and considers the different uses of manual welding and automatic welding. When selecting and designing welding positioner, in addition to the main displacement degree of freedom, we should also consider increasing the auxiliary displacement degree of freedom. For example, welding large pieces can increase the freedom of lifting movement, such as the American and German products mentioned above.
In addition, for some weldments, due to the simple distribution of welds, most of the ship welding requirements of important welds can be met with a degree of freedom of rotation, and a few non-important welds can be welded at right angles, although ship fillet welds cannot be implemented. In this way, in order to simplify the equipment cost, the welding positioner with single degree of freedom or degraded function is considered in the process, that is, the single-turn positioner. Auxiliary degrees of freedom can also be increased according to the use requirements. For example, lifting and tailstock movement.
And some shifters. In order to meet the technological requirements of welding station, some degrees of freedom of these welding positioner have nothing to do with welding. In addition, considering the design and stability of work station, two or more welding positioner are combined together, which produces a variety of work station transformation and combined multi-degree-of-freedom welding positioner products.
