As a typical automatic centering clamping device, the working principle and process of Spring collet are quite precise and efficient. The following is a detailed explanation of how Spring collet works to position and clamp the workpiece:
1. Overview of working principle
Spring collet mainly achieves the positioning and clamping of the workpiece through its unique structure and material properties. When the workpiece is placed in the center hole of Spring collet, the operating element will apply an axial pulling force in the backward direction to Spring collet. Under the action of this pulling force, the clamping part of Spring collet will produce a slight elastic deformation in the radial direction, making the hole diameter smaller, so as to achieve uniform clamping of the workpiece.
2. Specific working process
Workpiece placement: Place the workpiece to be processed into the center hole of Spring collet to ensure that the workpiece is aligned with the center of the chuck.
Applying pulling force: Apply axial pulling force in the backward direction to Spring collet through the operating element. This can be achieved by connecting and tightening the external thread of the machine tool spindle tie rod with the rear end internal thread of Spring collet.
Elastic deformation: Under the action of tension, the clamping part of the Spring collet will produce a slight elastic deformation in the radial direction, making the aperture smaller. This deformation is uniform and precise, which can ensure that the workpiece obtains uniform clamping force during the clamping process.
Positioning and clamping: As the aperture is reduced, the workpiece is precisely positioned in the center of the chuck and is evenly clamped. This positioning and clamping method can ensure the stability and accuracy of the workpiece during processing.
Processing process: After the workpiece is positioned and clamped, various processing operations such as turning and milling can be performed.
Release the workpiece: When the processing is completed, the external tension of the operating element is cancelled, and the elastic deformation of the Spring collet disappears under the action of its own rigidity, the aperture becomes larger, and the clamping state of the workpiece is cancelled. The workpiece can be removed manually or automatically at this time.
Spring collet achieves precise positioning and uniform clamping of the workpiece through its unique structure and material properties. This positioning and clamping method not only improves processing accuracy and stability, but also improves production efficiency. At the same time, Spring collet is easy and flexible to operate and can adapt to the processing needs of workpieces of different shapes and sizes.
