Problems solved by technology

The traditional angle welding fixture consists of two test plates, one end is fixed, and the other end is rotated. The fixed end limits the welding position and the movable end is easy to cause defects such as misalignment of the test piece, which virtually increases the consumption of manpower, material resources and other resources. The quality of the entire weldment

specific Embodiment approach

[0014] The preferred embodiment of the multi-angle welding fixture of the present invention is:

[0015] Including main plate rotation mechanism, sub-plate rotation mechanism and lap welding adjustment mechanism;

[0016] The main board rotation mechanism includes a bracket, a worm wheel, a key shaft, a worm, a bearing, a main board, and a copper pad. side and engages with the worm gear;

[0017] The sides of the main board are fastened to the groove plate by screws, two chute guide rails are fixed on the upper surface of the main board, and copper pads are also installed on the upper surface of the main board.

[0018] A copper backing is used to protect the backside of the weld.

[0019] The sub-board rotating mechanism includes a sub-board, two screws, and a rotating shaft. One end of the sub-board is connected to the main board through the rotating shaft.

[0020] The main board and the sub-board rotate around the same axis. The second screw connected to the side of th...

specific Embodiment

[0026] Such as figure 1 , figure 2 As shown, the multi-angle welding fixture includes a main board rotation mechanism, a sub-board rotation mechanism and a lap welding adjustment mechanism. The main board rotation mechanism is composed of a bracket 1, a worm wheel 2, a key shaft 3, a worm screw 4, a bearing 5, a main board 6, and a copper pad 18, wherein the main board 6 is connected to the worm wheel 2 through a key shaft 3, and the key shaft 3 is connected The bearing 5 is installed on the support 1, and the worm 4 is installed on the side of the support 6 to mesh with the worm wheel 2. The mainboard 6 sides are fastened groove dish 15 by screw three 17, and mainboard 6 upper surface is fixed with two chute guide rails 8 by screw, also adorns the copper liner 18 that is beneficial to butt weld backside forming.

[0027] Described sub-board rotating mechanism is made up of sub-board 13, screw two 14, groove plate 15, rotating shaft 16, screw three 17, wherein one end of su...

Abstract

The invention discloses a multi-angle welding jig which comprises a main board rotating mechanism, an auxiliary board rotating mechanism and a lap welding regulating mechanism. Butt joint, corner joint, T-shaped connection, lap joint and end connection welding of test pieces can be achieved. The main board rotating mechanism comprises a support, a worm gear, a spline shaft, a worm, a bearing, a main board and a copper liner. The auxiliary board rotating mechanism comprises an auxiliary board, a second screw, a groove disc, a rotating shaft and a third screw. The lap welding regulating mechanism comprises a lap joint board, a first screw, a sliding groove guide rail and a main board. A whole system is rational in structure, convenient to manufacture and simple and convenient to operate, the angle between the two test pieces can be regulated accurately and continuously, the adjustable range of the angle is larger than 300 degrees, and the shortcoming of test piece misalignment is overcome due to the spatial constraint of the rotating shaft.

Description

technical field [0001] The invention relates to a multi-angle welding fixture, which can realize butt joint, corner joint, T-joint, lap joint and end joint welding of test pieces. Background technique [0002] Welding fixture is the process equipment used for assembly and welding after the weldment is correctly positioned and clamped. Its reliability and flexibility directly affect the quality and efficiency of welding. The traditional angle welding fixture consists of two test plates, one end is fixed, and the other end is rotated. The fixed end limits the welding position and the movable end is easy to cause defects such as misalignment of the test piece, which virtually increases the consumption of manpower, material resources and other resources. the quality of the entire weldment. Contents of the invention [0003] The purpose of the present invention is to provide a multi-angle welding fixture with simple structure, reliable performance and large angle adjustable ra...
