TECHNICAL FIELD

[0001] The utility model relates to the technical field of clamp, especially relates to a vacuum chuck clamp. BACKGROUND

[0002] The main difficulties of thin-walled part machining include part wall thin deformation, tool wear quickly and low machining efficiency and the like problems. These problems are particularly prominent in the field of aerospace energy manufacturing, especially in the machining of titanium alloy thin-walled parts.

[0003] Specifically,

[0004] Deformation: thin-walled parts are prone to deformation during machining, making it difficult to control the size and shape accuracy. The reasons for deformation include internal stress redistribution, insufficient positioning surface flatness, improper clamping position, machining allowance and cutting force, cutting heat and unreasonable part structure, etc.

[0005] Tool wear: during thin-walled part machining, the tool is prone to wear, resulting in reduced machining efficiency and increased cost.

[0006] Low machining efficiency: traditional machining methods cannot balance machining efficiency and machining accuracy, resulting in long production cycle and high cost. Therefore, a new type of clamp is needed to solve the above problems. INVENTION CONTENTS

[0007] The utility model discloses a vacuum chuck clamp, which solves the technical problems of deformation and low efficiency of existing thin-walled parts during machining.

[0008] The vacuum chuck clamp of the utility model has a plurality of installation grooves for installing workpieces on the base, a plurality of air passages in the base, air passages in communication with each installation groove, a back-shaped installation frame in the installation groove, a supporting rod in the installation frame, and the air passages in communication with the installation frame.

[0009] Preferably, the workpiece lower part is provided with a supporting rod on both sides, and the supporting rod is placed outside the installation frame.

[0010] Preferably, the installation groove is provided with a groove on both sides.

[0011] Preferably, the installation frame is provided with a plurality of limiting convex grooves, and the workpiece inner side is provided with a limiting column corresponding to the limiting convex groove.

[0012] Preferably, the air passage is connected with a vacuum device to supply air for the vacuum chuck clamp.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] This vacuum suction cup clamp mainly includes a base with multiple mounting slots arranged in multiple rows to ensure that multiple workpieces can be processed at once. The mounting slots are used to mount and place workpieces. The base has an air passage, one end of which is connected to the mounting slot and the other end is connected to an external vacuum device to supply air to the vacuum suction cup clamp, thereby achieving the effect of clamping the workpiece. A mounting frame is set in the mounting slot, and a support rod is set in the mounting frame. The mounting frame has a U-shaped structure. The mounting frame and the support rod provide support and prevent the workpiece from being concave and deformed inward when vacuum suction is applied. Attached Figure Description
