Universal flexible jaw vice for machining

Abstract

The invention relates to the field of machining, in particular to a universal flexible jaw vice for machining. The jaw vice comprises a jaw vice base, and a parallel jaw vice seat and a movable jaw seat which are mounted on the jaw vice base, the movable jaw seat comprises an adjustable jaw seat and a movable jaw, the movable jaw is connected with the adjustable jaw seat under the action of a guide pin, a screw rod is rotated to drive the movable jaw and a jaw block to horizontally move on the guide pin together, a pin sleeve matched with the guide pin is embedded in the movable jaw, and the guide pin is in small clearance fit with the pin sleeve; and two flexible jaw blocks are symmetrically arranged in the movable jaw, and the flexible jaw blocks are rotary jaw blocks of 1 / 4 discs and are connected to the two ends of the movable jaw through two reamed hole bolts. The jaw vice is simple in structure, reliable in clamping, convenient to operate, capable of effectively reducing labor intensity, low in manufacturing and modification cost, capable of being self-adaptive to different shapes of contour surfaces of parts and easy to implement and maintain.

Description

technical field [0001] The invention relates to the field of machining, in particular to a general flexible vise for machining. Background technique [0002] Flat vise is the main fixture of planer, milling machine, drilling machine, grinding machine and slotting machine. It is widely used in milling machine, drilling machine, etc. to process various surfaces, grooves, angles and other parts. With the continuous development of advanced manufacturing industry, the contour shape of mechanical parts is becoming more and more complex, and the precision is getting higher and higher, while the clamping problem of machine tools has always affected the quality of parts. In addition, in order to meet the needs of market competition such as informatization, automation, and specialization in the processing and manufacturing industry, the design and manufacture of fixtures are particularly important. [0003] At present, the design and manufacture of fixtures at home and abroad are mai...
