Title
(EN) Pneumatic clamp for preventing metal part from deformation
(ZH) 一种防止金属零件变形的气动夹具
Abstract
(EN) The invention provides a pneumatic clamp for preventing a metal part from deformation. Thepneumatic clamp comprises a supporting rod and a workpiece, a first plug is arranged on one side of the supporting rod in a transmission connection mode, one end of the first plug is in transmission connection with a driving motor located at the other end of the supporting rod through a rotating shaft, the outer side of the first plug is sleeved with the workpiece, and the workpiece is of an internally hollow cylindrical structure. According to the pneumatic clamp, an outer clamping mechanism capable of being freely adjusted is arranged at the bottom of the workpiece, the outer side of the workpiece can be clamped through two arc-shaped clamping pieces on the outer clamping mechanism, meanwhile, ballsare arranged in the arc-shaped clamping pieces, so that the workpiece can be assisted in rotating, and the stability of the workpiece in the later machining process is guaranteed; and by means of cooperation of the first plug and a second plug, the first plug and the second plug can extrude and fix the workpiece from the interior of the workpiece, so that the condition that the workpiece is fixedfrom the interior and the exterior at the same time is ensured, the workpiece is prevented from deformation in the later machining process, and the stability of the workpiece is higher.
(ZH) 本发明提供一种防止金属零件变形的气动夹具,包括支撑杆和工件,支撑杆的一侧设置有传动连接有第一堵头,其中第一堵头的一端通过转轴与位于支撑杆另一端的驱动电机传动连接,第一堵头的外侧套接有工件,其中工件呈内部中空式圆柱形结构。本发明中,通过在工件的底部设置可自由调节的外夹持机构,通过外夹持机构上的两个弧形夹持件可对工件的外侧进行夹持,并同时弧形夹持件内部设置有滚珠,能够辅助工件进行转动,保证工件在后期加工时的稳定性,通过配合第一堵头和第二堵头,第一堵头和第二堵头可从工件的内部对工件进行挤压固定,进而保证工件从内部和外部同时固定,防止工件在后期加工时发生形变,使得工件稳定性更高。
