Abstract

The invention discloses an automatic welding fixture for an elbow. The fixture comprises a fixing rack (1), an adjusting rack (2) and the elbow (4) which are arranged correspondingly, wherein a first automatic lifting device capable of enabling the elbow (4) to move up and down is arranged on the adjusting rack (2), and a hydraulic locking device is fixed on the first automatic lifting device; and a second automatic lifting device corresponding to the first automatic lifting device is on the fixing rack (1), a second chuck (3) is arranged corresponding to the hydraulic locking device on the second automatic lifting device, and the elbow (4) is arranged between the hydraulic locking device and the second chuck (3). According to the fixture, the elbows can be welded automatically and appearance quality is high; the operating speed and height can be adjusted automatically; the fixture is suitable for elbow workpieces with the nominal diameter of 600mm-1200mm; the clamping is convenient and the working efficiency is improved; and the hydraulic locking device is adopted, accidents of the workpieces can be avoided during the operation, and the fixture is safe and reliable.

Description

technical field [0001] The invention relates to the production field of pipe fittings, in particular to an automatic elbow welding jig. Background technique [0002] The traditional elbow is usually firmly welded. Firstly, it is made into half of the elbow section, and then the two sections are welded together. The surface of the product produced by this method is rough. And in the welding process of the elbow, accidents are prone to occur during the operation of the workpiece, which poses a certain threat to the personal safety of the operating workers. Therefore, a fixture for clamping the elbow has appeared to facilitate welding. However, the existing fixture is difficult to clamp and cannot adjust the height. The nominal diameter of the clamping elbow is limited to a certain extent, and the scope of use is narrow. Contents of the invention [0003] In order to solve the problem that the use range of the tools for clamping the elbow is narrow and the clamping is diffic...
