Achieve the above object, base case of the present utility model is as follows: thrust clamping device, comprises pedestal, link gear and the boss for clamp shaft, the slide block, cavity and the groove that are provided with pilot hole in described pedestal, are slidably connected with pilot hole, described link gear comprises the jaw be articulated with on cavity inner wall, be slidably connected to the power rail on pedestal and gangbar, be articulated with the connecting plate on pedestal, be arranged at the pressing plate in groove, be fixed in the threaded rod on pressing plate, one end and the power rail of described jaw offset, the other end and the slide block of jaw are hinged, one end and the power rail of described connecting plate are hinged, the other end and the gangbar of connecting plate are hinged, described linkage board is slidably connected away from one end of connecting plate and pressing plate, described threaded rod is provided with extension spring through one end of pedestal and pedestal, the other end of threaded rod is connected with nut, described boss is arranged at pressing plate one end away from threaded rod.
The principle of base case: during operation, first promotes slide block and moves right; Then slide block drives one end of jaw to move right, the pin joint of jaw on pedestal is rotated counterclockwise, make the other end of jaw extrude power rail to be moved to the left, power rail drives one end of connecting plate to be moved to the left, the pin joint of connecting plate on pedestal turns clockwise, and makes the other end of connecting plate drive gangbar to move right, and gangbar extruding pressing plate moves right, threaded rod also moves right simultaneously, makes extension spring be in extended state; Move right finally by pressing plate, the boss on pressing plate and axle are offseted, realizes the clamping to axle with this.Otherwise pull slide block to be moved to the left, slide block drives one end of jaw to be moved to the left, the pin joint of jaw on pedestal turns clockwise, and makes the other end of jaw no longer extrude power rail, and now extension spring gives threaded rod one pulling force left, band dynamic pressure plate is moved to the left, and makes boss unclamp axle.
The advantage of base case: this programme drives jaw to be rotated counterclockwise mainly through promoting slide block, power rail, connecting plate and gangbar is coordinated to drive pressing plate to move right, boss and axle are offseted, the clamping to axle is realized with this, its overall structure is simple, easy to operate, and effectively raise the operating efficiency of machining shaft.
Preferred version one: based on the preferred version of scheme, described pedestal is provided with alignment pin, and one end of described alignment pin and pressing plate are slidably connected, by above-mentioned setting away from one end of boss, utilize alignment pin to prevent the rotation of pressing plate, limit pressing plate and move in the horizontal direction.
Preferred version two: the preferably preferred version of, described pressing plate is also provided with L-type plate, one end face of described L-type plate is arranged between nut and pressing plate, the other end of L-type plate is arranged on pedestal, by above-mentioned setting, because an end face of L-type plate is fixed on pressing plate, the other end of L-type plate is arranged on pedestal, limits push rod further and moves in the horizontal direction.
Preferred version three: the preferably preferred version of two, described boss is used for the projection that the end face of clamp shaft is provided with two arc-shapeds, by above-mentioned setting, replace plane to the clamping of axle by boss, reduce contact area, significantly reduce the wearing and tearing to brake rim, and plane holder mandrel compared by boss, impetus is more concentrated, also better to the clamping effect of axle.
Preferred version four: the preferably preferred version of three, described pin joint is all fixed on pedestal by bearing pin, by above-mentioned setting, bearing pin make cam and rocking arm more stable when pin joint rotates, and convenient for assembly and dismounting.
