The invention discloses a clamping device for anti-deformation stress release, which comprises a hydraulic component, a connecting rod, a fixing seat, a main body, a connecting component and a clamping component. A connecting rod is fixedly installed on the hydraulic component, and a connecting rod is fixed on A fixed seat is installed, and the fixed seat is fixedly connected with the main body through a connecting component. The clamping component is fixedly installed on the main body. When the hydraulic pressure is activated, the hydraulic part can squeeze the slider to move to the right, and at the same time squeeze the component spring , the force applied to the tooling by the component spring can be deformed to further disperse the force applied to the tooling, release the stress generated by the workpiece during processing, and then drive the hydraulic connecting rod to move to the right in the sliding hole through the slider, so that the fixed corner can withstand The ball top of the workpiece, because the fixed angle can increase the contact area with the workpiece, convert the point contact between the tooling and the workpiece into surface contact, and disperse the pressure, so that the clamping sleeve can hold the workpiece, so that the end surface of the workpiece and the stop of the positioning sleeve Fit to achieve the effect of clamping the workpiece.
Description
technical field [0001] The invention relates to the technical field of clamping devices for medical instruments, in particular to a clamping device for anti-deformation stress release. Background technique [0002] For grid structure products or thin-walled products, there are more complicated characteristics in actual processing. If they are not handled well, problems such as deformation may occur and affect the quality and accuracy of parts. When processing acetabular cups It is necessary to use a clamping device. In order to ensure the stability of the machining under different cutting forces, it is necessary to be able to determine the clamping force with the maximum cutting amount. In order to meet the precision requirements of the parts, when there is When the amount of material removal is large and the parts have high requirements in terms of precision, the roughing-finishing route can be used. [0003] During the clamping process, due to the surface grid structure o...
