Abstract

The invention provides a tapered wedge type clamping mechanism which comprises at least two clamping plates which are oppositely arranged, and further comprises a tapered wedge mechanism capable of driving the clamping plates to move horizontally; the tapered wedge mechanism comprises crank arm levers for driving the clamping plates to move horizontally, second tapered wedges for pushing the crankarm levers to rotate, first tapered wedges for pushing the second tapered wedges to move, and gears for driving the first tapered wedges to move horizontally; the gears are connected through a transmission shaft; the two gears on the transmission shafts rotate synchronously; and the gears drive the clamping plates to clamp or release a workpiece through the first tapered wedges, the second tapered wedges and the crank arm levers sequentially. The opening distance of the tapered wedge type clamping mechanism is increased effectively through the first tapered wedges, the second tapered wedges and the crank arm levers, and with the mutual combination of the crank arm levers, the first tapered wedges, the second tapered wedges and the gears, the clamping precision is improved effectively, andthe weight of the tapered wedge type clamping mechanism is reduced remarkably.

Description

technical field [0001] The invention relates to the field of mechanical clamping mechanisms, in particular to a wedge type clamping mechanism. Background technique [0002] The existing clamping chucks include rotatable pneumatic (or electric) self-centering six-jaw chucks. There are two types of chucks: wedge clamping and collet clamping. These two products are very popular in the market. Mature technology, there are a large number of professional manufacturers, the main technical parameters are similar, the defect of this type of product is that the accuracy of the chuck can only reach 0.025, the distance between the wedge type opening and clamping can only reach 6mm at most, the collet method Accuracy The distance between opening and clamping can only reach 2mm. The greater the opening, the worse the accuracy. The diameter must reach φ145, and the weight exceeds 100KG. None of the existing chucks can achieve high opening and high precision at the same time. skills requir...
