Abstract
Description
Technical Field
[0001] This utility model belongs to the field of welding equipment, specifically referring to a welding pre-positioning structure for automobile parts production. Background Technology
[0002] In automobile manufacturing, welding is one of the important processes for connecting parts, especially for complex components such as subframes. Welding often requires adjustments at multiple angles to ensure welding accuracy. With the development of the automotive industry, the requirements for welding accuracy and production efficiency are getting higher and higher.
[0003] Traditional welding positioning methods typically use fixed-angle worktables, which are difficult to meet the welding requirements of different tilt angles. During the clamping and fixing process, workers need to adjust the worktable to the required angle before fixing it. Furthermore, it is impossible to adjust the worktable to the required angle for support during the fixing process, resulting in complex clamping and low efficiency. Currently, the common solution is to use multi-degree-of-freedom robotic arms for positioning. Although this method is highly flexible, it is expensive and complex to operate. Utility Model Content
[0004] The technical problem this invention aims to solve is that fixed-structure clamping makes it difficult to meet welding requirements at different angles, and multi-degree-of-freedom robotic arms are costly.
[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: The welding pre-positioning structure for automobile parts production proposed by this utility model includes a worktable, a movable support plate, and a drive mechanism:
[0006] The movable support plate is rotatably connected to one end of the worktable, and the driving mechanism is located on the side of the worktable and connected to the movable support plate to control the rotation of the movable support plate.
[0007] The workbench and the movable support plate are symmetrically equipped with clamping mechanisms on both sides of the upper part.
[0008] Furthermore, rotating rods are fixed on both sides of the adjacent end of the movable support plate and the worktable. The rotating rods are rotatably connected to the side of the worktable, and one end of the rotating rod passes through the worktable.
[0009] Furthermore, the drive mechanism includes an electro-hydraulic push rod, a rack, and a gear. A mounting frame and a limiting plate are fixedly provided on the side of the worktable. The fixed end of the electro-hydraulic push rod is fixedly mounted on the mounting frame. The movable end of the electro-hydraulic push rod is fixedly connected to the rack. The rack and the limiting plate are slidably connected. The gear is rotatably located on the side of the worktable. One end of the rotating rod is fixedly connected to the gear. The rack and the gear are meshed and connected.
[0010] Furthermore, a limiting strip is fixedly provided on the outer side of the rack, and a limiting groove is provided on the inner side of the limiting plate. The limiting strip and the limiting groove are slidably fitted together.
[0011] Furthermore, the clamping mechanism includes a vertical plate, a hydraulic push rod, and a clamping plate. The vertical plate is fixedly mounted on the upper part of the workbench and the movable support plate, respectively. The fixed end of the hydraulic push rod is fixedly connected to the vertical plate, and the movable end of the hydraulic push rod is fixedly connected to the clamping plate.
[0012] Furthermore, the clamping mechanisms on both sides of the worktable and the movable support plate are symmetrically arranged.
[0013] Furthermore, the adjacent surfaces of the clamps on both sides are designed with anti-slip surfaces.
[0014] The beneficial effects of this utility model by adopting the above structure are as follows:
[0015] The proposed welding pre-positioning structure for automotive parts production uses a movable support plate and a worktable that are rotatably connected. A drive mechanism is installed on the outside of the worktable to start the movable support plate to rotate, thereby achieving the function of automatically adjusting the tilt level before welding. This facilitates the clamping and fixing of automotive parts with different tilt welding requirements, is easy to adjust, has a simple and reliable structure, moderate cost, and is easy to promote and use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1-3 As shown, this utility model proposes a welding pre-positioning structure for automotive component production, including a workbench 1. A mounting bracket 101 is fixedly mounted on one side of the workbench 1. It also includes a movable support plate 2 and a drive mechanism 3. The movable support plate 2 is rotatably connected to one end of the workbench 1. The drive mechanism 3 is located on the side of the workbench 1 and is connected to the movable support plate 2 to control its rotation. Rotating rods 201 are fixedly mounted on both sides of the adjacent end of the movable support plate 2 and the workbench 1. The rotating rods 201 are rotatably connected to the side of the workbench 1 via bearings, and one end of each rod passes through the workbench 1. The drive mechanism 3 includes an electro-hydraulic push rod 301, a rack 302, and a gear 303. The fixed end of the rod 301 is fixed on the mounting frame 101. The movable end of the electric hydraulic push rod 301 is fixed to the rack 302. A limiting plate 102 is fixed on the lower side of the mounting frame 1. The rack 302 and the limiting plate 102 are slidably connected. The gear 303 is rotatably located on the side of the workbench 1. One end of one of the rotating rods 201 is fixed to the gear 303. The rack 302 and the gear 303 are meshed and connected. A limiting strip 304 is fixed on the outer side of the rack 302. A limiting groove 305 is opened on the inner side of the limiting plate 102. The limiting strip 304 and the limiting groove 305 are slidably fitted together to assist in supporting and limiting the position and direction of movement of the rack 302.
[0024] like Figure 1 As shown, clamping mechanisms 4 are symmetrically arranged on both sides of the upper part of the workbench 1 and the movable support plate 2. The clamping mechanism 4 includes a vertical plate 401, a hydraulic push rod 402 and a clamping plate 403. The vertical plate 401 is fixedly installed on the upper part of the workbench 1 and the movable support plate 2 respectively. The fixed end of the hydraulic push rod 402 is fixedly connected to the vertical plate 401, and the movable end of the hydraulic push rod 402 is fixedly connected to the clamping plate 403. The clamping mechanisms 4 on both sides of the workbench 1 and the movable support plate 2 are symmetrically arranged. The adjacent surfaces of the clamping plates 403 on both sides are glued with anti-slip surface structures. The anti-slip surface structure can be selected from rubber anti-slip pads.
[0025] In practical use, a portion of the automotive subframe that needs to be welded at different angles is placed on the movable support plate 2 and fixed. The hydraulic push rod 402 on the movable support plate 2 is activated to control the movement of the clamping plate 403 to clamp and fix the placed component. According to the required welding angle, the electric hydraulic push rod 301 is activated to push the rack 302. Under the meshing transmission, the gear 303 and the rotating rod 201 are driven to rotate, thereby adjusting the angle between the movable support plate 2 and the worktable 1. After adjusting to the required welding angle, the other part of the automotive subframe is placed on the worktable 1 and moved to align with the welding point of the automotive subframe portion on the movable support plate 2. The hydraulic push rod 402 on the worktable 1 is activated to control the movement of the clamping plate 403 to clamp and fix the placed component. The self-locking function set in the electric hydraulic push rod 301 locks the position of the rack 302 and the tilt of the movable support plate 2. After fixing, the welding operation is carried out. The tilt position of the processed component is automatically adjusted according to the welding requirements, making adjustment convenient.
