Abstract
The utility model belongs to the technical field of machine tools and provides a self-centering fixture for a two-sided two-station milling and drilling combined machine tool. The self-centering fixture is formed by a hydraulic motor, a fixture body, a left-right-handed lead screw, a left-rotating nut, a right-rotating nut, nut bases, V-shaped clamping blocks and a coupler. The hydraulic motor is connected with the left-right-handed lead screw through the coupler, the left-right-handed lead screw is sleeved with the left-rotating nut and the right-rotating nut, the two nut bases are fixed to the two nuts respectively, and the two V-shaped clamping blocks are fixed to the two nut bases respectively. The self-centering fixture fully overcomes defects of an existing fixture, and is structurally formed by the hydraulic motor, the fixture body, the left-right-handed lead screw, the nut bases, the V-shaped clamping blocks, the coupler and the like. The hydraulic motor drives the left-right-handed lead screw through the coupler, then the left-right-handed lead screw drives the left-rotating nut base and the right-rotating nut base, and the V-shaped clamping blocks 1 and 2 are fixed to the nut bases, so that the purpose of clamping a workpiece is achieved. On the contrary, the hydraulic motor rotates reversely to loosen the workpiece.
Description
Technical field
The utility model relates to a kind of clamping device of mechanical processing industry milling Double End centering lathe.
Background technology
At present, the clamp mechanism of using on market adopts as shown in Figure 1 linear oil cylinder 1-6 to drive initiatively to clamp 1-5 more and driven pincers 1-3 realizes self-centering clamping workpiece.In figure, 1-1 is fixture stand.
The shortcoming of this fixture is:
1, clamp the restriction that stroke is subject to linear oil cylinder stroke, holding workpiece 1-4 can only be in very limited scope;
2, service life short, known, end face milling centering equipment is applicable to large batch of workpiece processing, is clamping and is loosening in process frequently, rack and pinion 1-2 only weares and teares in very little scope, is easy to cause tooth bar or gear to fall tooth and damages phenomenon;
3, positioning precision is poor, fixture in use rack and pinion can produce wear phenomenon, thereby produce larger gap, now initiatively pincers are directly promoted by oil cylinder, and driven pincers will be subject to the indirect action of tooth bar and gear to realize motion, once generation gap, initiatively pincers will produce asynchrony phenomenon with driven pincers.So center can be offset, and lose clamp precision.
Summary of the invention
The utility model object is to overcome the deficiency that existing double end milling machine rig fixture exists, and designs a kind of two-sided two station millings and bores building-block machine self-centering fixture.
Briefly, building-block machine self-centering fixture is bored in two-sided two station millings, it is characterized in that adopting fluid motor-driven left-right turning screw rod, then realizes by described leading screw drive left-right rotary nut seat two clamping V-block clamping work pieces that are fixed on nut seat.
Specifically, building-block machine self-centering fixture is bored in described two-sided two station millings, it is characterized in that being comprised of fluid-power motor, clamp body, left-right turning screw rod, left-right rotary screw, nut seat, clamping V-block and shaft coupling.Fluid-power motor is connected with left-right turning screw rod by shaft coupling, and two nut sleeves of left rotation and right rotation are on left-right turning screw rod, and two nut seats are separately fixed on two screws, and two clamp V-block and are separately fixed on two nut seats.
Described leading screw adopts hardened steel fine grinding to form, and described screw adopts wear-resisting copper material to process.
The utility model has solved the deficiency of existing fixture completely, and its framework is comprised of 6 parts such as fluid-power motor, clamp body, positive and reverse return leading screw, nut seat, clamping V-type body and shaft couplings.
Its operation principle is by shaft coupling, to drive left-right turning screw rod by fluid-power motor, then drives left-right rotary nut seat by leading screw, and clamping V-type 1,2 is fixed on nut seat, thereby realizes the object of clamping work pieces, otherwise fluid-power motor reversion realizes loosening of workpiece.
The advantage of this fixture is:
1, fluid-power motor can unlimited rotary, and stroke is just unrestricted, and clamping diameter range just increases greatly;
2, leading screw adopts hardened steel fine grinding to form, and screw adopts wear-resisting copper material to process, and during rotation, full-depth tooth engagement, has improved service life greatly;
3, by left-right turning screw rod and screw, solved two and clamped the nonsynchronous problem of V-type, even if produce gap between screw and leading screw, because leading screw is whole one, regardless of active, driven, remained synchronous clamping or loosen, thereby having solved the poor deficiency of positioning precision.

Fig. 1 is existing jig structure chart.
Fig. 2 is the utility model structural representation.
The specific embodiment
Provided as shown in Figure 2 the utility model specific embodiment.Building-block machine self-centering fixture is bored in two-sided two station millings, it is characterized in that adopting fluid motor-driven positive and reverse return leading screw, then realizes by described leading screw drive positive and reverse return nut seat two clamping V-block clamping work pieces that are fixed on nut seat.It is comprised of fluid-power motor 6, clamp body, left-right turning screw rod 4, left-right rotary screw 1, nut seat 2, clamping V-block 3 and shaft coupling 5, fluid-power motor 6 is connected with positive and reverse return leading screw 4 by shaft coupling 5, two screws 1 of left rotation and right rotation are enclosed within on left-right turning screw rod 4, two nut seats 2 are separately fixed on two screws 1, and two clamp V-block 3 and are separately fixed on two nut seats 2.Described leading screw 4 adopts hardened steel fine grinding to form, and described screw 1 adopts wear-resisting copper material to process.
