Description
Technical field
The present invention relates to field of fixtures, be specifically related to a kind of Wedge type clamping device of axle.
Background technology
In a broad sense, any operation in technical process, is used for rapidly, installs easily and safely the device of workpiece, all can be described as fixture.Such as weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often referred to as fixture.On lathe during processing work, the dimensions reaching drawing for making the surface energy of workpiece and specify, geometry and with the technical requirements such as the relative-position error on other surfaces, workpiece must be installed before processing, clip.Fixture is made up of setting element, clamping device, tool setting induction element, indexing means, Connection Element and clamp body etc. usually.Fixture and grip device are widely known by the people, and are widely used for manufacturing.Particularly, fixture has various reference surface and point, and parts or instrument can accurately be located.In many process, this is general to clamp member, so that these parts can keep correct juxtaposition relationship in such as punching press, riveted joint, welding, the process of pasting or solidifying.
Axle is through the cylindrical object in the middle of bearing or in the middle of wheel or in the middle of gear, but also have small part to be square.Axle is the machine components that support rotary part turning round therewith transmits motion, moment of torsion or moment of flexure.Be generally round metal shaft-like, each section can have different diameters.The part doing gyration in machine is just contained on axle.Along with the development of Chinese national economy, also growing to the demand of axle, according to different demand, axle needs for further processing, and the fixture therefore for machining shaft is of crucial importance, and the usual overall structure of existing fixture is more complicated, operate more loaded down with trivial details, reduce the operating efficiency to axle processing.
Summary of the invention
The invention is intended to provide the Wedge type clamping device of the axle that a kind of structure is simple, easy to operate, operating efficiency is high.
Achieve the above object, base case of the present invention is as follows: the Wedge type clamping device of axle, comprise fixed mechanism, driving mechanism and hold-down mechanism, described fixed mechanism comprises pedestal, for the projection of placing axle and the supporting seat be arranged on pedestal, be provided with transverse holes and vertical hole in described pedestal, described transverse holes and vertical hole are mutually vertical and be communicated with; The actuating unit that described driving mechanism comprises push pedal, is fixedly connected with push pedal, the clamping limb be positioned on supporting seat and the declivity tapered bar be arranged in transverse holes is provided with in described push pedal, be provided with the upper wedge bar offseted with declivity tapered bar in described vertical hole, between described push pedal and pedestal, be provided with lower stage clip; Described hold-down mechanism comprises the pressing plate for compression axis, described pressing plate and pedestal hinged, one end of described pressing plate is fixedly connected with upper wedge bar one end away from declivity tapered bar.
The principle of base case and advantage: during operation, be first positioned on boss by axle; Then push pedal is driven to be moved to the left by actuating unit, push pedal drives clamping limb to be moved to the left together with declivity tapered bar, the upper wedge bar of declivity tapered bar extruding moves up, because upper wedge bar is fixedly connected with pressing plate, upper wedge bar band dynamic pressure plate moves up away from one end of compression axis, pressing plate turns clockwise around its pin joint, and the other end of pressing plate and the upper end of axle offset, and clamping limb offsets away from one end of push pedal and the right-hand member of axle simultaneously; Finally by boss and axle a left side, lower end offsets, clamping limb is away from one end of push pedal and the right-hand member of axle offsets and pressing plate offsets away from upper one end of wedge bar and the upper end of axle, realize the clamping to axle with this, now descend stage clip to be in impaction state.Otherwise, lower stage clip gives push pedal one thrust to the right, push pedal drives clamping limb to move right together with declivity tapered bar, because declivity tapered bar no longer extrudes upper wedge bar, upper wedge bar band dynamic pressure plate moves down away from one end of compression axis, the pressing plate other end is separated with the upper end of axle, and clamping limb is separated with the right-hand member of axle away from one end of push pedal simultaneously, realizes unclamping axle with this.This programme mainly promotes push pedal by actuating unit and is moved to the left, and coordinate the clamping of clamping limb, declivity tapered bar, upper wedge bar and pressing plate realization to axle, its overall structure is simple, easy to operate, effectively raises the operating efficiency of machining shaft.
Preferred version one: based on the preferred version of scheme, described actuating unit comprises fixed head, screw rod, is fixedly connected with the fore-set of push pedal and fixed head, described screw rod is fixedly connected with push pedal through fixed head, described screw rod being connected with nut is arranged on fixed head, by above-mentioned setting, drive fixed head to be moved to the left by tightening nuts, fore-set drives push pedal to be moved to the left, give push pedal one power left, realize the clamping to axle.
Preferred version two: the preferably preferred version of; the packing ring of rubber is provided with between described nut and fixed head; by above-mentioned setting; packing ring has certain elasticity; the surface of fixed head can be protected not to be subject to the wearing and tearing of nut; add the service life of fixed head, effectively save cost.
Preferred version three: the preferably preferred version of two, is provided with compression spring between described push pedal and fixed head, by above-mentioned setting, stage clip has very strong compression capability, and when tightening nuts, fixed head promotes push pedal and is moved to the left, realize the clamping to axle, now compression spring is in impaction state; When unscrewing nut, compression spring gives fixed head one thrust to the right, and fixed head drives push pedal to move right faster, effectively decreases the time of unclamping axle.
Preferred version four: the preferably preferred version of three, described pressing plate is provided with the knee of L-type away from one end of compression axis, extension spring is provided with between described knee and pedestal, by above-mentioned setting, extension spring has certain tension force, and because the upper wedge bar of declivity tapered bar extruding moves up, upper wedge bar band dynamic pressure plate moves away from one end of compression axis, the other end compression axis of pressing plate, now extension spring is in extended state; Instantly wedge bar no longer extrudes wedge bar, and extension spring gives pressing plate away from the downward pulling force in one end of compression axis, and the other end accelerating pressing plate unclamps the time of axle.
Preferred version five: based on the another preferred version of scheme, described pressing plate by bearing pin and pedestal hinged, by above-mentioned setting, bearing pin makes pressing plate more stable when pin joint rotates, and convenient for assembly and dismounting.
