Description

Technical Field

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

[0002] As the foundation of the automotive industry, auto parts are necessary factors to support the sustainable and healthy development of the automotive industry. There are many types of auto parts, among which tubular auto parts are also a type of auto parts. When tubular auto parts are being processed, a positioning mechanism is required to position them in the appropriate position.

[0003] For example, Chinese patent publication number CN220575697U discloses a positioning mechanism for automobile parts processing, which belongs to the field of automobile parts processing technology, including a connecting assembly, wherein a driving assembly and a transmission assembly are provided in the connecting assembly, and four adjusting assemblies and four guide assemblies are provided on the connecting assembly, and the transmission assembly is connected to the four adjusting assemblies; the utility model controls the operation of the driving assembly, and when the forces acting on the clamping assembly are consistent, the driving assembly automatically stops working, and the four clamping assemblies that are close to or far away from each other position the tubular automobile parts to a position coaxial with the transmission assembly, so that the positioning mechanism is not likely to cause damage to the tubular automobile parts due to large forces during the positioning process, and because the strokes of the four adjusting assemblies are long, the four clamping assemblies that are close to or far away from each other can position tubular automobile parts of a larger size range, thereby improving the applicability of the device;

[0004] The technical solution recorded in this proposal utilizes a threaded rod to pull the movable plate to move and clamp and fix the cylindrical parts. However, since the threaded rod and the guide assembly are both arranged at the bottom end of the movable plate, when the movable plate moves inward to clamp the cylindrical parts, since its force point is at the bottom end, the clamping force at the bottom end is greater than the clamping force at the upper end of the movable plate, resulting in an unbalanced clamping force of the clamping plate, affecting the clamping effect of the parts.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a positioning mechanism for automobile parts processing is provided, in order to achieve a purpose with greater practical value. Utility Model Content
