Abstract
The utility model relates to a machining mechanism, in particular to a tight-pushing mechanism for fixing a workpiece. The floating type pneumatic tight-pushing mechanism comprises a base, a support, a tight-pushing end, a sliding shaft, a floating connector, an air cylinder, an extending-out beam and an air cylinder support. The support is fixedly connected to the base. The extending-out beam is fixedly connected to the support. The sliding shaft is movably connected to the support. The end of the sliding shaft is connected with the floating connector and the air cylinder in sequence. The end of the other side of the sliding shaft is provided with a tight-pushing end. The outer portion of the tight-pushing end is of a cone structure. A gap is arranged between the tight-pushing end and the sliding shaft. The gap is arranged between the tight-pushing end and the sliding shaft. When a certain distance exists between the rotating center of a workpiece and the center axis of the sliding shaft and the distance is smaller than the size of the gap at the same time, the tight-pushing end can move in the radial direction relative to the sliding shaft, and floating type tight pushing is achieved.
Description
Technical field
The utility model relates to a kind of machining mechanism, particularly a kind of jacking mechanism that workpiece is fixed.
Background technology
On machined and weld jig, often require fixture quick-clamping and accurately locate.Common jacking mechanism has the tailstock of lathe.It adopts the mode of hand drive to clamp, complex operation.
The for example jacking mechanism of tail stock class, the centre of gyration of its tailstock center and lathe chuck needs highly coaxial, and no person can affect the quality of institute's converted products; Moreover the adjusting of tail stock is more loaded down with trivial details, takes time and effort.
The utility model proposes a kind of can raising the efficiency, the jacking mechanism of compact conformation.
Utility model content
The purpose of this utility model is to provide a kind of floating type pneumatic jacking mechanism, and the utility model is applied to mechanical manufacturing field, and to realize fixing to workpiece, the utility model adopts pneumatic element as driving, has improved operating efficiency; Meanwhile, adopt the floating type terminal that holds out against to act on workpiece as holding out against element, in the time that workpiece need to rotate, also can flexible rotating.
A kind of floating type pneumatic jacking mechanism, comprises base, support, holds out against terminal, sliding axle, floating junction, cylinder, stretches out beam, air cylinder support; Described support is fixed on described base, described in stretch out beam and be fixed on described support, described sliding axle is movably connected on described support; Connect successively described floating junction and described cylinder in the end of described sliding axle, be provided with and hold out against terminal in the end of described sliding axle opposite side, described in hold out against terminal outside become conical structure; Be provided with gap described holding out against between terminal and described sliding axle.
Preferably, the size in described gap is between 0.5mm to 2mm.
Preferably, described sliding axle is cylindrical structural, on described support, is provided with sliding bearing, and described sliding axle and described sliding bearing match, and described sliding axle is through described sliding bearing.
The beneficial effect of the utility model floating type pneumatic jacking mechanism:
Described sliding axle is movably connected on described support, under the driving of described cylinder, realizes the action of stretching out and retracting, and manner of execution is convenient and swift.
The described terminal that holds out against acts on workpiece as holding out against element, and in the time that workpiece need to rotate, workpiece can flexible rotating.
Be provided with gap described holding out against between terminal and described sliding axle.In the time that the pivot of workpiece and the central axis of described sliding axle exist certain distance, this distance is less than the size in gap simultaneously, described in hold out against terminal can be with respect to described sliding axle generation radial motion, to realize floating type holding out against.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but does not form any restriction of the present utility model, in accompanying drawing, similarly element numbers represents similar element.
A kind of floating type pneumatic jacking mechanism, comprises base 1, support 2, holds out against terminal 3, sliding axle 4, floating junction 5, cylinder 6, stretches out beam 7, air cylinder support 8; Described support 2 is fixed on described base 1, described in stretch out beam 7 and be fixed on described support 2, described sliding axle 4 is movably connected on described support 2; Connect successively described floating junction 5 and described cylinder 6 in the end of described sliding axle 4, be provided with and hold out against terminal 3 in the end of described sliding axle 4 opposite sides, described in hold out against terminal 3 outside become conical structure; Be provided with gap 51 described holding out against between terminal 3 and the boss 41 of described sliding axle 4.
More specifically, be connected with pad 11 and bolt 12 in the end of described sliding axle 4.Described pad 11 and described in hold out against and between terminal 3, also have gap.Described pad 11 comes off from described boss 41 for holding out against terminal 3 described in preventing.More specifically, the size in described gap is between 0.5mm to 2mm.More specifically, described sliding axle is cylindrical structural, on described support, is provided with sliding bearing, and described sliding axle and described sliding bearing match, and described sliding axle is through described sliding bearing.
Below in conjunction with Fig. 1 to 3, further describe operation principle of the present utility model and the course of work:
Described sliding axle 4 is movably connected on described support 2, under the driving of described cylinder 6, realizes the action of stretching out and retracting, and manner of execution is convenient and swift.The described terminal 3 that holds out against acts on workpiece as holding out against element, and in the time that workpiece need to rotate, workpiece can flexible rotating.Be provided with gap 51 described holding out against between terminal 3 and described sliding axle 4.In the time there is certain distance in the pivot of workpiece and the central axis of described sliding axle 4, this distance is less than the size in gap simultaneously, can there is radial motion with respect to described sliding axle 4 in the described terminal 3 that holds out against, the described terminal 3 that holds out against moves with workpiece, to realize floating type holding out against.
