Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a three-point circle clamp. Background Art

[0002] A three-point circular fixture is a fixture used to position and clamp a workpiece. It typically consists of three positioning points and a corresponding clamping mechanism. This fixture is designed to ensure that the workpiece maintains a stable and precise position during machining, thereby ensuring machining accuracy and product quality. The working principle of a three-point circular fixture is based on the basic principle of geometry: three points define a circle. By securing the workpiece with three positioning points, it can be ensured that the workpiece remains stationary within two planes perpendicular to the pins, thereby achieving precise control and machining of the workpiece. To improve the efficiency of automotive parts machining, a three-point circular fixture is required. However, existing three-point circular fixtures still have the following shortcomings:

[0003] For example, the utility model with publication number CN221416367U discloses a fixture for processing automobile parts. The utility model drives the driving wheel by motor 2, and drives the driven wheel to rotate together through a belt, thereby driving the positive and negative screw rods to rotate, so that the clamping plate is clamped close to the center, and then driven by motor 1 to rotate, which solves the problem of being unable to flip the clamped parts independently. However, similar to the comparative documents of the above-mentioned application, when the existing three-point circle clamp is used, since most three-point circle clamps do not have a structure for auxiliary positioning of the product, it is difficult to quickly fix and limit the product during the processing process, resulting in a decrease in the practicality of the three-point circle clamp and a decrease in its use efficiency.

[0004] Therefore, in view of this, the existing structure and defects were studied and improved, and a three-point circle clamp was proposed. Utility Model Content
