Abstract

The invention discloses a quick clamping device, which comprises a press block, a clamp body, a clamping screw, an anti-rotating pin, a handle, a mandril, a spring, a gland and a positioning pin, wherein the clamping screw is in threaded connection with the clamp body; the right end of the clamping screw is provided with the handle; the mandril is in clearance fit with the clamping screw; the anti-rotating pin can prevent the rotation of the clamping screw; the other side of an anti-rotating bolt on the clamping screw is provided with the positioning pin for preventing the backward movement of the mandril; and the spring and the gland are arranged between the anti-rotating pin and the positioning pin; and the head of the mandril is provided with the swing smooth-surfaced press block or groove-surfaced press block. The quick clamping device has the advantages of simple structure, low requirements on size and accuracy, quick clamping, convenient and fast travel adjustment, and the like.

Description

technical field [0001] The invention relates to a machining equipment, in particular to a quick clamping device. Background technique [0002] As we all know, the screw clamping mechanism is the most widely used clamping mechanism. It mainly uses threads to directly clamp the workpiece, or forms a composite clamping mechanism with other components or mechanisms to clamp the workpiece. The screw clamping mechanism has the advantages of simple structure, easy manufacture, reliable clamping, large force ratio, and unlimited stroke. But at the same time, it also has the disadvantages of slow clamping action, long auxiliary time, and low efficiency. Especially when workpieces of different sizes are alternately clamped frequently with the same fixture, it is necessary to continuously rotate the screw to change the stroke (such as a profile cutting machine). In order to make the screw clamping mechanism play a better role, make full use of strengths and avoid weaknesses. Various...
