specific Embodiment approach 1

[0026] Embodiment 1: Combining figure 1 Illustrating this embodiment, an automatic inner support fixture assembled before welding of special-shaped components in this embodiment includes a base module, a motion module, a power module and a control module;

[0027] The base module consists of a base 1, an end positioning plate 2, an end cover A7, an end cover B10 and a shaft end block 11;

[0028] The motion module is composed of a wedge-shaped spacer 3, a connecting rod 4, a connecting rod block 5, a casing 6, a return spring 8, a roller 9, an inner support shaft 12 and a top block 13;

[0029] The power module is composed of a shaft sleeve 14, a positioning sleeve 15, an output screw 16, a reducer 17 and a servo motor 18;

[0030] The control module consists of a mechanical sensor built in the wedge-shaped spacer 3 and a control box 19 located behind the servo motor;

[0031] The base 1 is an I-shaped wheel structure, the end positioning plate 2 is a disc structure with hol...

specific Embodiment approach 2

[0036] Specific implementation mode 2: Combining figure 1 This embodiment is described. The difference between this embodiment and the specific embodiment 1 is that the number of the wedge-shaped spacers 3, connecting rods 4, connecting rod blocks 5, return springs 8, rollers 9 and top blocks 13 are all six. . Other compositions and connection methods are the same as those in the first embodiment.

specific Embodiment approach 3

[0037] Specific implementation three: combination figure 1 Describing this embodiment, the difference between this embodiment and the specific embodiment 1 is that the movement range of the wedge-shaped spacer 3 in the radial direction is 0-30 mm.

[0038] Other compositions and connection methods are the same as those in the first embodiment.

Abstract

An automatic internal support tooling fixture for pre-welding assembly of special-shaped components, which relates to a tooling fixture, and the invention aims to solve the problems of inaccurate centering, loose clamping and poor assembly accuracy during pre-welding assembly of special-shaped structures such as shells and low assembly efficiency. The fixture includes a base module, a motion module, a power module and a control module; the motion module is located on the end face of the base module, and the power module and the control module are built in the base module. When the fixture is working, the control module controls the power module to output power. The motion module located on the end face is driven by the power module to clamp the workpiece. The base module is used for positioning during the clamping process and for controlling the control module and power. module for protection. The invention is applied in the field of welding.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to an automatic inner support tooling fixture for special-shaped components assembled before welding. Background technique [0002] Welding technology occupies an extremely important position in today's national manufacturing industry, and has been more and more widely used. After decades of development, welding technology has formed a relatively complete system in my country's energy industry, transportation industry, aerospace industry and marine engineering. In recent years, with the development of modern welding technology and the needs of the manufacturing industry, scientific and rational design of tooling and fixtures has become more and more important. The prerequisite for welding parts is to make the fixtures install and fix each part accurately and scientifically. The fixture has a direct and key influence on the quality, cost and productivity of the welding of parts. Compared with t...
