Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a ground positioning system. Background Art

[0002] Positioning the automobile frame before machining is a crucial step. As an important load-bearing structure of the automobile, the machining accuracy of the frame directly affects the overall performance and safety of the automobile. Through precise positioning, the position and size of the frame during machining can be ensured to be accurate, thereby ensuring that the machined frame meets the design requirements. Positioning can reduce the adjustment and trial and error time during the machining process, allowing operators to enter the machining state more quickly, thereby improving production efficiency.

[0003] Currently, during the frame processing, manual measurement and positioning of the frame are required, resulting in limited positioning accuracy, which in turn affects the processing quality and subsequent assembly effects. Manual positioning and adjustment of the frame position takes a long time and is prone to errors, resulting in low production efficiency. In addition, frequent shutdowns, adjustments and rework will further reduce production efficiency. Manual operation and positioning may pose safety hazards, such as equipment damage or personal injury caused by improper operation. In addition, errors in the processing process may also affect product safety. Utility Model Content

When the staff places the frame to be processed on the ground positioning frame 1, the second roller 9 and the first roller 6 can effectively lift and support the frame, and after the frame is positioned, the second roller 9 and the first roller 6 can transport the frame so that the frame can be subsequently processed.

[0024] The height of the top of the guide seat 12 is lower than the height of the second roller 9, and the positioning rod 13 is slidably connected to the inner wall of the guide seat 12. When the frame is placed above the ground positioning frame 1, the guide seat 12 can avoid collision with the bottom of the frame, so as to facilitate subsequent movement of the frame.

[0025] The adjustment structure 14 includes a fixing plate 141, a screw 142, an adjustment slot 143, a nut 144 and a connecting plate 145. The fixing plate 141 is slidably connected to the left and right sides of the surface of one side of the ground positioning frame 1.

The output shaft of the cylinder 10 pushes the positioning rod 13 to rise, and the positioning rod 13 is inserted into the corresponding positioning hole on the surface of the frame. If it cannot be inserted, the position of the frame needs to be adjusted. After the positioning is completed, the staff controls the cylinder 10 to open again, so that the positioning rod 13 falls again, and the staff can push the frame to move. The first roller 6 and the second roller 9 below rotate to transport the frame so that subsequent processing operations can be performed on the frame after positioning.
