Abstract
A clamp and quick change mechanism for plate-like tool which includes reduction box assembly from which an output shaft extends out. The end of the said output shaft is equipped with projection. And first spring, first clamping strap clamping strap, saw blade, as well as second clamping strap component are cased on the projection. A cam wheel pair is arranged between support plate and the second clamping strap of the second clamping strap assembly. First groove and axial groove are opened on the support plate, and disassembly and assembly actions of the saw blade are realized by cooperating the projection with the first groove or the axial groovy. The saw blade is shifted between clamping state and loading state by relative raise or falling between two groups of cam surface making up of the cam wheel pair.
Description
Technical field
The present invention relates to a kind of clamping and fast replacing device of plate-like instrument.
Background technology
In the prior art; saw blade as electric circular saw, diagonal cutting saw; and the clamping of the plate-like instruments such as grinding wheel of angle grinding machine; in the traditional design; the common pressing plate of general employing clamps; and it is fastening in addition by the threaded engagement between output shaft and nut or the screw; the inertia friction of the clamping meeting of this threaded engagement plate-like instrument because of the vibration of plate-like instrument in the cutting or when shutting down fluffs fastening threaded engagement; thereby can not clamp the plate-like instrument well, even have the plate-like instrument is flown out and the danger of hurting sb.'s feelings from the axle of at a high speed rotation.And, when the plate-like instrument is installed, also need aids such as screwdriver or spanner to tighten, also brought inconvenience to the user.Provide a kind of manual operation just can clamp the flange of plate-like instrument fast among U.S. Pat-A-5388942 (February 14 nineteen ninety-five is open), by the twisting ring-shaped article, pin on the ring-shaped article promotes middleware, the face of pearl up and down of the ball on the middleware is slided along the ascent direction of the projection that is oppositely arranged on chassis and the top board respectively, produce axial compressive force, and, after middleware turns over certain angle, the chassis is locked by relative with middleware, can not relatively rotate again, this moment, the plate-like instrument was clamped, oppositely twists ring-shaped article in the time of need unloading the plate-like instrument whole device disengaging locking state is got final product.The shortcoming of this device is, the various and a plurality of parts of part complex-shaped, thus this device complexity, structure manufacturing cost height, and whole device is installed the assembly difficulty.
Summary of the invention
The present invention aims to provide a kind of clamping and the fast replacing device that manually just can change the plate-like instrument of plate-like instrument fast.
The invention provides a kind of clamping and fast replacing device of plate-like instrument, comprise the reduction box assembly, one output shaft passes from described reduction box assembly, end at described output shaft is provided with projection, and be with first spring on the described output shaft successively, first pressing plate, saw blade, and second Anchor plate kit, described second Anchor plate kit includes second pressing plate, gripper shoe, and the connector that second pressing plate and gripper shoe are linked together, have groove and axial groove on the described gripper shoe, when described projection matches with described groove, described saw blade is in the state of loading onto, described gripper shoe is provided with first group of cam surface, described second pressing plate is provided with second group of cam surface, described first group of cam surface is corresponding with the shape of described second group of cam surface, when described gripper shoe during by described output shaft driven rotary, the described relatively second group of cam surface of described first group of cam surface rotates and rises, this moment, saw blade was clamped, when described output shaft stops the rotation, described rise falls after rise, at this moment, described saw blade returns to the described state of loading onto, and after described projection was deviate from from described axial groove, described saw blade can unload from described output shaft.
The present invention compared with prior art has following advantage:
During the machine dismounting, manual operation gets final product, and does not need aid; In the course of work, reliable clamping anti-loose situation can not appear; Part is less, and is cheap for manufacturing cost; The dismounting operating process is simple and reliable.
