Problems solved by technology
[0003] The existing thermal calibration fixture has a complex structure and poor versatility. Usually, one calibration fixture corrects a titanium alloy thin-walled welded component. The calibration method of this method increases the calibration cost and reduces the production efficiency of the product. In addition, the correction effect and efficiency of the correction fixture and method used are far from meeting the requirements, and it is difficult to meet the requirements of thermal correction of titanium alloy thin-walled parts

Embodiment
[0048] A batch calibration fixture, such as Figure 1 to Figure 3 As shown, it includes a lower die 1 for assembling the part to be calibrated and an upper die 2 matched with the lower die and used for clamping the part to be calibrated. A profile 3, the lower end face of the upper die 2 is provided with a second profile 4 corresponding to the first profile, the first profile 3 and the second profile 4 are assembled to form a profile correction cavity and used for assembling Correction pieces.
[0049] In this embodiment, a set of fixtures are provided with multiple profiles for shape correction to realize shape correction of more thin-walled titanium alloy welding components. Compared with the traditional process, this design makes full use of the clamping surface area of the fixture, and uses as much of the limited area as possible for shape correction. In this design, the part to be calibrated is a thin-walled titanium alloy welded component. Due to the characteristics ...

The invention discloses a shape correction clamp, particularly relates to a batched shape correction clamp for a thin-walled titanium alloy welding assembly and belongs to the technical field of aerospace devices. The device comprises a lower mold for assembling a workpiece to-be-corrected in shape and an upper mold matched with the lower mold used for clamping the workpiece to-be-corrected in shape. Multiple first molded surfaces matched with the shape correction shape are arranged on the end face of the upper portion of the lower mold. Second molded surfaces are arranged on the end face of the lower portion of the upper mold. A shape correction cavity is formed after the first molded surfaces and the second molded surfaces are assembled and is used for assembling the workpiece to-be-corrected in shape. By the adoption of the batched shape correction clamp for the thin-walled titanium alloy welding assembly, the problems that the function of a traditional shape correction clamp is singular, and the production efficiency is low are solved, through the ingenious design, the production efficiency is improved effectively in combination with the shape correction process, and large-batch workpieces to-be-corrected in shape can be corrected in shape due to optimization of the process and optimization of the assembly design.
Description
technical field [0001] The invention relates to a shape correction fixture, in particular to a batch shape correction fixture and a shape correction method for thin-walled titanium alloy welding components, belonging to the technical field of aerospace devices. Background technique [0002] Titanium alloy is a material with good thermoplasticity and is easily deformed by heat. Therefore, thin-walled parts made of such materials are prone to deformation during welding and heat treatment, especially thin-walled parts with complex shapes. The deformation is more serious. The material is titanium alloy parts that meet the design requirements, and must be calibrated after welding, and a calibration jig must be used during heat treatment. [0003] The existing thermal calibration fixture has a complex structure and poor versatility. Usually, a calibration fixture is used to shape a titanium alloy thin-walled welded component. The calibration method of this method increases the cal...
