Description

Technical Field

[0001] The utility model relates to the technical field of hinge shaft production, in particular to a hinge shaft positioning device. Background Art

[0002] Hinge shafts are widely used in various mechanical devices, such as doors and windows, machinery and equipment, and automotive parts. They are used to connect parts and allow them to rotate around a fixed axis, thereby realizing the movement and function of the mechanical device. The main purpose of using a positioning device in the processing of hinge shafts is to ensure processing accuracy and product quality. The positioning device can help accurately position the workpiece on the processing equipment, so that it can maintain a fixed position and direction during the processing process, prevent the workpiece from shifting, shaking or misaligning, thereby ensuring processing accuracy and consistency;

[0003] The conventional hinge shaft positioning device reserves a positioning pin on the workbench that matches the positioning hole or groove on the hinge shaft. The hinge shaft is placed on the workbench so that it corresponds to the positioning pin in the workbench. The positioning pin matches the positioning hole or groove of the hinge shaft, which fixes the hinge shaft at a specific position on the workbench and keeps it stable.

[0004] The traditional hinge shaft positioning device has the following problems: if the sizes of the hinge shafts are different, it may be necessary to prepare positioning pins of various sizes to accommodate hinge shafts of different sizes, and positioning pins of different sizes need to be frequently replaced, which will increase the preparation time before processing and reduce production efficiency. For this reason, we propose a hinge shaft positioning device. Utility Model Content

The second slide groove is symmetrically distributed front and back with the adjacent first slide groove, and the inner wall of the second slide groove is slidably connected to the bottom end of the adjacent positioning block to provide sliding support.

[0011] Furthermore, the positioning mechanism also includes a rotating shaft, a rack plate and a gear. The rotating shaft is rotatably connected to the bottom wall of the workbench, and a gear is fixedly sleeved on the upper end of the rotating shaft.
