Technical Field

[0001] This utility model relates to the technical field of deburring fixtures, specifically a quick clamping device for deburring and chamfering. Background Technology

[0002] After processing, some parts require deburring or chamfering on corresponding edges. Due to the different sizes and shapes of the parts, existing technologies require different clamping devices to be set according to the shape of the parts during deburring or chamfering. This allows the upper grinding wheel to reliably grind the corresponding edges of the parts, thereby completing the deburring or chamfering operation. In actual operation, it is necessary to change the corresponding clamping device according to different workpieces, resulting in high manufacturing costs and time-consuming and labor-intensive replacement of the clamping device, leading to low production efficiency. Therefore, there is an urgent need to develop a universal clamping device. Utility Model Content
