Description

Technical Field

[0001] The present application relates to the technical field of processing and clamping devices, and more specifically, to a rapid clamping device for precision metal processing. Background Art

[0002] When clamping precision metal workpieces, it is necessary to ensure that the metal workpieces remain stable during the processing. Otherwise, it may affect the processing accuracy and efficiency. This requires an appropriate clamping force, correct position, and high precision. Otherwise, during processing, the workpiece will be unstable due to improper clamping position, and the clamping efficiency of the clamping device is also one of the important factors reflecting the processing efficiency of precision metal workpieces. A clamping mechanism for precision sheet metal processing proposed in the existing public technology number CN210360435U. This device can perform blanking operations on different types of sheet metal by using a turntable that can rotate and tilt, enabling the sheet metal to move stably to the desired clamping mechanism without falling, eliminating the need for manual movement of the sheet metal. Then, through three different types of clamping mechanisms, different types of sheet metal can be clamped, improving the clamping effect of the device on the sheet metal and facilitating the processing operation of the staff on the sheet metal. In view of the above-mentioned related technologies, the utility model person believes that there are still the following defects: The clamping device in the comparative literature cannot perform center calibration operations on precision metal parts when clamping them. As a result, when changing the processing operation of precision metal parts, it is necessary to re-calibrate the precision metal parts and the tool, resulting in low processing efficiency and reduced clamping efficiency. In view of this, we propose a rapid clamping device for precision metal processing. Summary of the Utility Model

[0004] The purpose of the present application is to provide a rapid clamping device for precision metal processing, which solves the technical problem that the clamping device in the comparative literature in the above background art cannot perform center calibration operations on precision metal parts when clamping them. As a result, when changing the processing operation of precision metal parts, it is necessary to re-calibrate the precision metal parts and the tool, resulting in low processing efficiency and reduced clamping efficiency. The rapid clamping device realizes the embedded positioning installation of the positioning disk and the processing equipment installation base by using the arc groove and the center hole, and uses bolts for positioning. The positioning disk is simultaneously installed with three center positioning mechanisms and three clamping mechanisms, and the center positioning mechanisms and the clamping mechanisms are arranged at intervals. By synchronously starting three first cylinders, the top block moves towards the center hole to achieve the center positioning effect of the precision metal part. By synchronously starting three second cylinders, the mounting block moves towards the center hole, and then the threaded rod is locked, so that the T-shaped pressing seat slides along the two guide rods. The three T-shaped pressing seats are evenly distributed along the circumference of the precision metal part, enabling the precision metal part to be quickly clamped stably and with high firmness.
