High-stability clamping mechanism for annular workpiece

Abstract

The invention discloses a high-stability clamping mechanism for an annular workpiece. The high-stability clamping mechanism comprises supporting mechanisms, a connecting motor, a connecting support, a transmission shaft, positioning supports, connecting mechanisms, guiding devices, a connecting cylinder, limiting mechanisms and limiting rollers, and the upper end faces of the connecting mechanisms are fixedly connected with the positioning supports used for limiting. By arranging the supporting mechanisms, the connecting mechanisms and the guiding devices, when the workpiece is clamped, the guiding devices can drive the four supporting mechanisms to rotate at the same time through guiding gears, and therefore the multiple supporting mechanisms can drive the limiting mechanisms to conduct adaptive elastic limiting on the interior of the annular workpiece at the same time, and the clamping stability is improved; and meanwhile, positioning clamping blocks can be limited through the guide gears and limiting sliding grooves, the workpiece limiting accuracy of the device can be improved to the maximum degree, and then the subsequent clamping limiting or conveying stability is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a clamping mechanism for an annular workpiece with strong stability. Background technique [0002] In the process of workpiece production and processing, fixtures are indispensable. Fixtures can fix and limit the processing objects during the process of mechanical manufacturing of products or workpieces, or quickly clamp and transport the processed workpieces. In order to improve the efficiency of processing or conveying products or workpieces, [0003] However, when the existing workpiece clamping mechanism clamps and limits the annular workpiece, the stability of clamping the inner wall of the annular workpiece is insufficient, and it is easy to cause the annular workpiece to fall during the clamping and conveying process, which in turn leads to the life of the workpiece.

Problems solved by technology

[0003] However, when the existing workpiece clamping mechanism clamps and limits the annular workpiece, the stability of clamping the inner wall of the annular workpiece is insufficient, and it is easy to cause the annular workpiece to fall during the clamping and conveying process, which in turn leads to the life of the workpiece. At the same time, the adaptability of the existing workpiece clamping mechanism is insufficient, and it cannot adapt to workpieces with different radii, which reduces the convenience of the device. Therefore, there is an urgent need for a stable annular workpiece clamping mechanism to solve the above existing problems.
