The invention relates to the technical field of welding clamping tools, in particular to a clamping device. The clamping device provided by the embodiment of the invention comprises a clamping piece and an adjusting frame used for adjusting the height and the angle of the clamping piece, and the adjusting frame comprises an angle adjusting piece and a height adjusting piece used for adjusting the angle adjusting piece to ascend and descend. According to the clamping device, in the using process, the height of the angle adjusting piece is adjusted through the height adjusting piece, and then the height of the clamping piece is adjusted; the angle of the clamping piece is adjusted through the angle adjusting piece, and then the rotating angle of a to-be-clamped piece is adjusted conveniently, the height and the direction of the to-be-clamped piece can be rotated freely, and a welder can operate conveniently; and angle scale marks are arranged on the outer side wall of a rotating pipe, and then the accuracy of the rotating angle of the to-be-clamped piece is guaranteed, the accuracy of flat welding and vertical welding can be guaranteed, the welding position is in a standardized state, and relevant standard requirements are met.
Description
technical field [0001] The invention relates to the technical field of welding clamping tools, in particular to a clamping device. Background technique [0002] Welding technology is widely used in the manufacturing industry. Relevant standards require welders to be trained and process parameters tested before manufacturing. For example, in the ISO9606 welder certification standard, welders are required to carry out flat welding, vertical welding, horizontal welding and For the examination of welding positions such as overhead welding, the test plate with a groove type of a certain thickness is generally selected for welding, and then evaluated according to the requirements of the standard. Before welding, the test plate is spot-welded, and then on a special device, the welding is performed in strict accordance with the specified welding position. Generally, it is performed on a fixture, but generally lacks control of precise welding positions. [0003] In the prior art sol...
