A Surface Adaptive Fixture Based on Motor-Spring Mechanism and Its Working Method

Abstract

The invention discloses a curved surface self-adaptive fixture based on a motor-spring mechanism. The fixture comprises a workpiece, a fixed frame, a pressing device, a spring and an operation mechanism, wherein the pressing device consists of a connecting plate and a pressing rod; the workpiece is arranged on a working table; the fixed frame is arranged on the working table, and is movably connected with the operation mechanism through a connecting shaft; the connecting plate is arranged in a fixing device; the pressing rod is arranged on the connecting plate; the spring coats the connecting plate; and the operation mechanism is arranged at one end of the fixed frame. The curved surface self-adaptive fixture based on the motor-spring mechanism coats the spring on the pressing rod to enable the pressing rod to perform self-adaptive adjustment in downward pressing process according to the workpiece surface flatness, so that the downward pressing quality is greatly improved, the application range of the motor fixture is widened, and the fixture preferably satisfies production demands.

Description

technical field [0001] The invention relates to a clamp, in particular to a curved surface adaptive clamp based on a motor-spring mechanism and a working method thereof. Background technique [0002] With the rapid development of social economy, science and technology are also constantly developing. In order to better meet the needs of society, all walks of life are constantly accelerating their own development pace. The same is true in the processing and manufacturing industries, where most industries have replaced manual labor through mechanized production. [0003] For example, in the process of workpiece processing, it is often necessary to press the surface. Due to the different types of workpieces, some of the surfaces are relatively flat, and some have uneven surfaces. However, although the existing motor fixtures have a large Improve its production efficiency, and in the process of pressing down, the compression rod will not be adjusted according to the flatness of ...

Problems solved by technology

[0003] For example, in the process of workpiece processing, it is often necessary to press the surface. Due to the different types of workpieces, some of the surfaces are relatively flat, and some of the surfaces are uneven surfaces. However, although the existing motor fixtures have a large Improve its production efficiency, and in the process of pressing down, the compression rod will not be adjusted according to the flatness of the workpiece surface, so the pressing quality of the workpiece with a relatively flat surface will not have too much deviation, and for the curved surface Due to the uneven surface of the workpiece, in the process of pressing down, the pressing rod is also pressed down in one step. If the force is too large, it will lead to unqualified pressing of the workpiece, or even crush the curved surface of the workpiece surface, and the yield rate is low. Low, unable to meet the needs of production, so the existing motor fixtures can not really meet the needs of production
