Description
Technical Field
[0001] This utility model relates to the field of automotive parts welding technology, and in particular to an angle adjustment mechanism for welding automotive parts. Background Technology
[0002] As the automotive industry continues to introduce new models and automobile production increases, the demands on workers to operate faster and the requirements for welding quality and accuracy also become higher. During the welding process of automotive parts, it is necessary to use fixtures to clamp the automotive parts. However, the existing fixtures are not convenient for the welding angle of the automotive parts after clamping them. Sometimes it is necessary to repeatedly disassemble and reassemble the automotive parts, which will affect the welding effect.
[0003] Furthermore, some automotive parts have a non-planar bottom structure, making them inconvenient to clamp and fix.
[0004] Chinese utility model patent CN 220330449 U discloses an angle adjustment fixture for welding automotive parts, including a base plate with a support mechanism at its bottom. A rotating seat is fixedly connected to the center of the top surface of the base plate, and a rotating ball is engaged with the top of the rotating seat. In this utility model, the automotive parts are placed on a fixture platform, and a first electric push rod drives a clamping block to move and fix the automotive parts. When it is necessary to change the welding angle of the automotive parts, multiple first electric hydraulic rods are activated to extend or retract, changing the height of the support ball at the top of the multiple first electric hydraulic rods supporting the fixture platform. This causes the fixture platform to rotate around the rotating ball, thereby adjusting the angle of the automotive parts on the fixture platform. This facilitates welding operations and has good practicality.

[0039] Hereinafter, an angle adjustment mechanism for welding automotive parts, which is one embodiment of the present invention, will be described with reference to the accompanying drawings.
[0040] Please refer to Figures 1-4 As shown, an angle adjustment mechanism for welding automotive parts includes a clamping mechanism and an adjustment mechanism. The clamping mechanism is used to clamp the automotive parts, and the adjustment mechanism is used to adjust the angle of the clamping mechanism that clamps the automotive parts.
[0041] Regarding the clamping mechanism, it includes:
[0042] Main body 1 is used as a load-bearing installation component;
[0043] The clamping screw 101 passes through the main body 1 and is slidably disposed with the main body 1;
[0044] Specifically, the main body 1 has a through hole for accommodating the clamping screw 101;
[0045] The clamping nut 101-1 is assembled on the clamping screw 101;
[0046] The clamping plate 101-2 is fixed to the outer wall of the clamping screw 101;
[0047] In use, the clamping plate 101-2 and the clamping nut 101-1 are located outside the clamping bolt and on both sides of the main body 1. When a workpiece is placed on one side of the main body 1, the clamping plate 101-2 is moved around the clamping nut 101-1 until the clamping plate 101-2 can clamp the workpiece with the end face of the main body 1. Then, the clamping nut 101-1 on the other side of the main body 1 that is compatible with the clamping screw 101 is rotated, thereby realizing the clamping of the workpiece by the clamping plate 101-2 and the main body 1.
[0048] The clamping plate 101-2, the clamping screw 101, and the clamping nut 101-1 are each provided in at least 3 units, and are located on the outside of the main body 1 and are evenly distributed in a circle.
[0049] Because the clamping screw 101 is slidably set with the main body 1, and in conjunction with the clamping nut 101-1, it can clamp workpieces of different specifications.
[0050] The clamping mechanism also includes a positioning pin 102, which is threadedly assembled with the main body 1;
[0051] Specifically, the main body 1 is provided with a threaded hole that matches the positioning post 102, and the positioning post 102 is provided with an external thread that matches the threaded hole on its outer side.
[0052] When in use, the operator rotates the positioning column 102 and adjusts the position of the positioning column 102 relative to the end face of the main body 1 based on the bolt and nut assembly principle until the positioning column 102 can support the workpiece, thereby improving the clamping stability of the clamping mechanism on the workpiece.
[0053] Regarding regulatory bodies, including:
[0054] Fixing sleeve 103 is provided on the end face of the main body 1;
[0055] Specifically, the fixing sleeve 103 is disposed on the end face of the main body 1 on the side away from the clamping plate 101-2;
[0056] More specifically, the fixing sleeve 103 is welded to the main body 1;
[0057] The fixed column 103-1 is rotatably installed inside the fixed sleeve 103;
[0058] Specifically, a protrusion is provided on the inner side of the fixing sleeve 103 to prevent the fixing post 103-1 from detaching from the fixing sleeve 103;
[0059] The connecting column 103-3 is located on the end face of the fixed column 103-1 away from the main body 1;
[0060] That is, the connecting column 103-3 is fixed to a plane, and the main body 1 can rotate about the axis of the fixed column 103-1 relative to the plane;
[0061] Fastening screw 103-2 is installed through fixing post 103-1;
[0062] Specifically, at least one fastening screw 103-2 is provided, and the fixing post 103-1 is provided with a threaded through hole that is compatible with the fastening screw 103-2;
[0063] A handwheel (not shown in the figure) is provided at the end of the fastening screw 103-2 away from the main body 1;
[0064] When in use, the operator turns the handwheel, thereby turning the fastening screw 103-2. Based on the principle of thread transmission, the fastening screw 103-2 is pushed to the end face of the inner side of the fixing sleeve 103 near the main body 1, so as to realize the limit between the fixing sleeve 103 and the fixing column 103-1. That is, the connecting column 103-3 and the main body 1 can rotate and have the limit function.
[0065] The regulating mechanism also includes:
[0066] The first rocker arm 2 is installed on the end face of the connecting column 103-3 away from the main body 1;
[0067] The second rocker arm 201 is rotatably connected to the first rocker arm 2 via a rotating plate 202;
[0068] Fastening screws 203 and fastening nuts are installed through the rotating plate 202;
[0069] When in use, the operator rotates the first rocker arm 2 and the second rocker arm 201 to a suitable position (the suitable position is the position that is convenient for welding the workpiece / automotive parts), tightens the fastening nut, and uses the fastening screw 203 to press the rotating plate 202, thereby achieving relative fixation of the first rocker arm 2 and the second rocker arm 201.
[0070] Mounting flange 2-1 is located at the end of the second rocker arm 201 away from the first rocker arm 2, and is used to fix the second rocker arm 201 to the working plane;
[0071] The rocker arm assembly consists of the first rocker arm 2, the second rocker arm 201, the rotating plate 202, the fastening screw 203, and the fastening nut. The number of rocker arm assemblies is set to at least one. When the actual working conditions require it, the operator can add the rocker arm assembly to the end of the second rocker arm 201 according to the connection method of the first rocker arm 2 and the second rocker arm 201. The rotation direction of the rocker arm assembly is set according to the actual processing conditions, which facilitates the angle adjustment of the automotive parts.
[0072] Normal usage status
[0073] Workers select an appropriate number of rocker arm assemblies based on the workpiece shape and processing requirements, and fix at least one clamping mechanism and adjustment mechanism to the working plane (in automotive parts welding, if workpiece A is to be welded to workpiece B, workpiece B is fixed on the tooling, and the aforementioned working plane is the plane on one side of the tooling; after installation, the main body 1 of the clamping mechanism is close to the tooling) via the mounting flange 2-1. The workpiece to be welded is clamped onto the main body 1 via the clamping mechanism, and the main body 1 is deflected and rotated via the adjustment mechanism until the workpiece clamped on the main body 1 and the weld seam of the workpiece to be welded are aligned, and the welding operation is performed.
[0074] Compared with the prior art, this utility model has the following characteristics:
