Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, and in particular relates to a flexible welding tooling for vehicle body panels. Background Technology

[0002] The flexible welding fixture for vehicle body panels is a modular welding and positioning equipment for large covering parts such as the side panels and front panels of automobiles. Its core is to enable the co-production of multiple vehicle models through replaceable components and standardized interfaces. When welding the outer panels, it is inconvenient to limit and fix the outer panels, which reduces the stability of the welding. Therefore, a flexible welding fixture for vehicle body panels is needed.

[0003] For example, Chinese patent CN220093548U discloses a welding fixture for a reactor core conduit assembly, including: a base, six columns, several convex fixture rings, and a top cover plate. The outer circumferential contour of each convex fixture ring corresponds to and matches the inner wall contour of the core conduit plate on the reactor core conduit assembly. The bottoms of the six columns are fixedly connected to the platform of the base, and the six columns are distributed in a rotationally symmetrical manner around the central vertical axis of the platform. Several connecting plates are fixedly installed at intervals from top to bottom on the inner wall of each column. After the top cover plate is placed on the top surface of the six columns, it is fixedly connected to the top of each column through a corresponding detachable connection structure.

[0004] The existing technical documents have the following problems:

[0005] Existing technical documents have some drawbacks in use, such as: difficulty in limiting and fixing the outer panels during welding, thus reducing the stability of the welding process; and difficulty in controlling the spacing at the weld joint when welding between outer panels, leading to deformation and defects, thereby reducing the welding quality. Therefore, we propose a flexible welding fixture for vehicle body outer panels. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned technical problems by providing a flexible welding fixture for vehicle body panels, which facilitates the limiting and fixing of the outer panels and allows for easy control of the welding spacing.

[0007] In view of this, the present invention provides a flexible welding fixture for vehicle body panels, including a connecting frame, and further comprising: a positioning strip fixedly installed on one side of the connecting frame, adjusting shims equidistantly installed at the bottom of the positioning strip, a fixing shaft fixedly installed on one side of the positioning strip, an adjusting bushing fixedly installed at the bottom end inside the fixing shaft, a limit post through-installed at the top of the adjusting bushing, a welding frame fixedly installed at the bottom of the connecting frame, a positioning seat fixedly installed at the top of the welding frame, a connecting arm fixedly installed at one end of the positioning seat, a fixing block fixedly installed at the top of the connecting arm, and a gap plate fixedly installed at the top of the fixing block.

[0008] Based on the above structure, the adjustment bushing and the limiting post are used together to clamp the edge of the outer plate, thereby fixing and limiting the irregular outer plate. The spacer is installed using the fixing block. Then, the spacer is used to facilitate the adjustment of the spacing at the welding point when welding the outer plate, ensuring that the welded parts are in the theoretical assembly position and reducing dimensional deviations caused by thermal deformation.

[0009] Preferably, a positioning block is fixedly installed at one end of the connecting frame, and a pressure arm is fixedly installed between the positioning blocks, thereby using the positioning block to connect and install the pressure arm.

[0010] Preferably, a connecting sleeve is movably installed on the top of the pressure arm, and a pair of pliers is fixedly installed on the other side of the connecting sleeve, so as to connect the pair of pliers using the connecting sleeve.

[0011] Preferably, a handle is fixedly installed on one side of the fixed shaft. The handle is made of alloy material, which facilitates the use of the fixed shaft.

[0012] Preferably, an installation block is fixedly installed on the other side of the welding frame, and a telescopic pin assembly is fixedly installed on the top of the installation block, which facilitates the fastening and adjustment of the outer panel.

[0013] Preferably, a positioning pin is installed through the surface of the telescopic pin assembly to limit the telescopic pin assembly.

[0014] The beneficial effects of this utility model are:

[0015] 1. This flexible welding fixture for vehicle body outer panels uses positioning strips to install adjusting shims, then positioning strips to install and connect a fixed shaft, then the fixed shaft to install an adjusting bushing, and finally the adjusting bushing to install a limiting post. When limiting the outer panel, the adjusting bushing and the limiting post work together to clamp the edge of the outer panel, thereby fixing and limiting the irregular outer panel and improving the stability of welding irregular outer panels.

[0016] 2. This flexible welding fixture for vehicle body outer panels uses a welding frame to install a positioning seat, then uses the positioning seat to install and connect a connecting arm, then uses the connecting arm to install a fixing block, and then uses the fixing block to install a spacer. During welding of the outer panel, the connecting arm facilitates the connection between the fixing block and the positioning seat, and the fixing block is used to install the spacer. The spacer then allows for adjustment of the welding distance during welding, ensuring the welded components are in their theoretical assembly position, reducing dimensional deviations caused by thermal deformation, and thus improving the quality of the outer panel welding.
