[0023] Please refer to Figures 1-3 An auxiliary clamping device for steel pipe processing as shown, which includes a workbench 1. There are several fixed bases 1a on the workbench 1. A clamping tooling 2 is provided on the fixed base 1a. The clamping tooling 2 includes a top fixing plate 2a and side plates 2b. The top fixing plate 2a and the side plates 2b are fixedly connected. There is a threaded hole in the top fixing plate 2a. A threaded column 3 is provided in the threaded hole. A pressing component 4 is provided below the top fixing plate 2a. One end of the threaded column 3 is fixedly connected to the pressing component 4. The pressing component 4 includes a lower pressing plate 4a, a hollow slot 4b and a plug pin 4c. The side plate 2b is arranged in the hollow slot 4b. A sliding slot 2c is opened on the side plate 2b. A cushion block 5 is provided below the lower pressing plate 4a. A cushion block 5 is also provided below the side plate 2b. A slot 6 is provided at the bottom of the side plate 2b.
[0024] The slot 6 is in a rectangular hollow shape. The fixed base 1a is rectangular. The slot 6 covers the fixed base 1a. The clamping tooling 2 is connected to the fixed base 1a through the slot 6. During use, the slot 6 is inserted on the fixed base 1a, and the entire clamping tooling 2 can be fixed on the workbench 1 through the slot 6. And there are several fixed bases 1a with a fixed distance left, used to clamp steel pipes of different lengths. The number of clamping toolings 2 can be reduced or increased according to the length of the steel pipe, or the relative distance can be shortened by reducing the middle clamping tooling 2, which is suitable for steel pipe welding.
[0025] A handle 3a is provided at the top of the threaded column 3. The threaded column 3 is rotated through the handle 3a and cooperates with the thread so that the threaded column 3 can rise or fall through the top fixing plate 2a, thereby driving the pressing component 4 to rise or fall, so as to clamp the steel pipe.
[0026] Please refer to Figure 2 , the top fixing plate 2a is in an I-shaped structure. The top of the side plate 2b and the top fixing plate 2a are fixedly connected by bolts. Both the top fixing plate 2a and the side plate 2b are of double-layer structures, which is convenient for connection between them.
[0027] The side plate 2b is L-shaped, the sliding groove 2c is obliquely grooved, the side plate 2b is a double-layer structure, the side plate 2b includes an inner side plate 2ba and an outer side plate 2bb, a connecting shaft 2bc is provided between the inner side plate 2ba and the outer side plate 2bb, a cushion block 5 is provided at the end of the side plate 2b to form a bottom support, and the lower pressing plate 4a is connected to the sliding groove 2c through a pin 4c and can move in the sliding groove 2c driven by the pin 4c. When the lower pressing assembly 4 presses down through the threaded column 3, the lower pressing plate 4a slides obliquely downward along the sliding groove 2c. Through the hollowing of the hollow groove 4b, there is no obstruction during the downward sliding process, so that the lower pressing plate 4a can reciprocate along the sliding groove 2c.
[0028] The lower pressing plate 4a is also I-shaped, the hollow groove 4b is also obliquely grooved, and the pin 4c is inserted into the sliding groove 2c.
[0029] The cushion block 5 is made of rubber or polyurethane. One side of the cushion block 5 is arc-shaped, and the cushion block 5 is used to contact the surface of the steel pipe to form clamping and protection.
[0030] The specific working principle is as follows: Place an appropriate number of clamping tools 2 according to the length of the steel pipe, and pass the steel pipe through several clamping tools 2. The cushion block 5 on the side plate 2b forms a bottom support for the steel pipe. Then, turn the threaded column 3 to drive the lower pressing assembly 4 to press down until the cushion block 5 on the lower pressing plate 4a contacts the surface of the steel pipe and forms clamping. At this time, subsequent processing of the steel pipe can be carried out.
