Description

Technical Field

[0001] This utility model relates to the field of automotive parts welding technology, and in particular to a positioning mechanism and its automotive parts welding device. Background Technology

[0002] Currently, many automotive parts need to be connected and fixed by welding, especially some metal sheets. Due to usage requirements, it is necessary to press the end face of one sheet against the side wall of another sheet and keep them at a preset angle before welding.

[0003] In existing technologies, for welding metal sheets at a preset angle, workers need to position the two metal sheets before using a welding torch. However, there are currently no specific auxiliary tools for positioning the metal sheets. Workers mainly rely on measuring and positioning the sheets manually to perform preliminary welding and then supplementary welding. This not only increases the difficulty of the work but also affects the stability of the welding quality, which is not conducive to the stable and efficient operation of the welding work. Therefore, we propose a positioning mechanism and its automotive parts welding device. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figures 1-3 The positioning mechanism shown includes a base plate 100, with a vertically upward-facing vertical plate 101 integrally formed on the back of the base plate 100. An adjusting plate 103 is rotatably connected to the bottom of the vertical plate 101. A clamping mechanism is provided at the top of the adjusting plate 103. A positioning component is positioned between the adjusting plate 103 and the vertical plate 101, locking the position of the adjusting plate 103 after it rotates along the vertical plate 101. A pressing mechanism is located at the top of the base plate 100. By integrally forming the vertically upward-facing vertical plate 101 on the back of the base plate 100 and rotatably mounting the adjusting plate 103 on it, the clamping mechanism mounted on the adjusting plate 103 can clamp the workpiece to be welded. The positioning component locks the position of the adjusting plate 103, allowing for adjustment of the tilt angle of the workpiece clamped by the clamping mechanism. Then, the pressing mechanism horizontally presses another workpiece to be welded, resulting in an adjustable tilt angle between the two workpieces and stable positioning without the need for manual support, making subsequent welding operations more convenient and efficient.

[0019] The positioning component includes an L-shaped plate 110, which is fixedly connected to the top of the back of the adjusting plate 103. The top of the vertical plate 101 is an arc shape with its center corresponding to the rotation point of the adjusting plate 103. The inner side of the L-shaped plate 110 is slidably sleeved with the outer wall of the vertical plate 101. The clamping bolt 111 is threaded into the bottom of the back of the L-shaped plate 110, and one end of the clamping bolt 111 abuts against the back of the vertical plate 101. After the adjusting plate 103 is rotated to the designated position on the front of the vertical plate 101, the clamping bolt 111 is simply turned clockwise to press one end of the clamping bolt 111 against the back of the vertical plate 101. The clamping force is used to lock the position of the adjusting plate 103 and the vertical plate 101. The operation is simple and convenient, and the positioning is stable.

[0020] The clamping mechanism includes a clamping frame 105 and a first knob screw 107. A clamping plate 106 is movably mounted inside the clamping frame 105. The first knob screw 107 is threaded into one side of the clamping frame 105, and one end of the first knob screw 107 extends into the inner side of the clamping frame 105 and is rotatably connected to the middle of the clamping plate 106. By turning the first knob screw 107, the clamping plate 106 is driven to move within the clamping frame 105, thus clamping the workpiece by cooperating with the inner wall of the clamping frame 105. Fixed; A connecting rod 104 is fixedly connected to the back of the clamping frame 105. An assembly screw 108 is fixedly connected to one end of the connecting rod 104 away from the clamping frame 105. The end of the assembly screw 108 passes through the back of the adjusting plate 103 and is threadedly connected to a clamping nut 109. When it is necessary to adjust the angle of the workpiece clamped by the clamping mechanism, simply loosen the clamping nut 109 and then rotate the connecting rod 104 to make the adjustment. After the adjustment is completed, simply tighten the clamping nut 109 again. The operation is simple and convenient.

[0021] The clamping mechanism includes a pressure plate 112 and a translational drive component. A stepped groove 102 is formed at the top of the base plate 100. The pressure plate 112 is movably fitted to the bottom of the stepped groove 102. The translational drive component is fixedly installed on the front side of the stepped groove 102 and is used to drive the pressure plate 112 to move towards the inner wall of the stepped groove 102. Preferably, the translational drive component includes a nut seat 113 and a second knob screw 114. The nut seat 113 is fixedly connected to the front side of the stepped groove 102, and the outer wall of the second knob screw 114 is connected to the nut seat 113. The second knob screw 114 is rotatably connected to the middle of the pressure plate 112 via a central threaded connection. The workpiece is placed against the inner wall of the stepped groove 102. By driving the second knob screw 114 to rotate, and cooperating with the threaded connection between the second knob screw 114 and the nut seat 113, the second knob screw 114 can be rotated while pushing the pressure plate 112 to move horizontally towards the inner wall of the stepped groove 102, thereby pressing and positioning the workpiece. It should be noted that the outer wall of the second knob screw 114 needs to be cleaned after each use to avoid affecting subsequent use.
