Description
Technical field
The utility model relates to a kind of fixture, specifically, relates to major axis special fixture, belongs to processing and manufacturing technical field.
Background technology
Major axis is a kind of common machine components, workpiece production being accustomed to be greater than by length-to-diameter 10 ~ 20 times is called major axis, because the rigidity of major axis own is poor, in process, easily occur buckling phenomenon, have a strong impact on the machining accuracies such as cylindricity, concentricity and surface roughness, fraction defective is higher, economic benefit is poor, therefore, production uses usually special fixture carry out clamping to major axis and fix, effectively can reduce fraction defective.But, existing major axis special fixture is set directly in the middle of workpiece usually, although the L/D ratio value of major axis can be made to reduce half, promote the rigidity of major axis to a certain extent, improve machining accuracy, but the bending stress that major axis produces because of self gravitation cannot be offset completely, the part gravity of major axis tail end also can affect the straightness of whole axle, bad phenomenon still occurs often, factory need to bear with absorb to scrap pressure still larger, therefore economic loss to a certain degree can be caused, be unfavorable for the QT Quality Target of factory and reaching of profit target, therefore, a kind of clamping is reasonable, clamping stability is high, the major axis special fixture that crudy is good is urgently released.
Summary of the invention
For the problems referred to above that prior art exists, the purpose of this utility model is to provide major axis special fixture, by the structure of appropriate design fixture, makes major axis clamping reasonable, clamping stability and reliability good, promote crudy, reduce and produce line fraction defective.
For realizing above-mentioned utility model object, the technical solution adopted in the utility model is as follows:
Major axis special fixture, comprise a bearing and multiple securing member, wherein, holder top have one put in, the V-shaped groove that runs through of head and the tail, bearing two side is symmetrically arranged with the guide-track groove that twice head and the tail run through, multiple securing member is arranged on bearing evenly and at intervals along guide-track groove direction, each securing member includes support, adjusting rod and clamping plate, support is provided with two slide blocks, support is arranged on the guide-track groove of bearing both sides by two slide blocks, and clamping plate are arranged on the top of V-shaped groove and are movably connected on support body by adjusting rod.
Preferably, the material of major axis special fixture adopts the carbon steel or stainless steel that moulding processability is good.
Preferably, the shape of cross section of guide-track groove is rectangle, T-shaped or swallow-tail form.
Preferably, major axis special fixture comprises three securing members, holds before, during and after three securing members are arranged on bearing evenly and at intervals along guide-track groove direction.
Preferably, consider machine-shaping convenience, Bracket setting is arched door shape.
Preferably, adjusting rod is screw rod, and cradle top has a threaded connection hole, and adjusting rod and support are spirally connected.
More preferably, conveniently control clamping plate action neatly, adjusting rod is provided with one handle or handwheel.
Preferably, in order to better carry out clamping to major axis, arc shape is arranged to by clamping plate, can better fit with major axis outer circumference surface, promotes clamping stability.
Relative to prior art, the beneficial effects of the utility model are: by the structure of appropriate design fixture, make major axis clamping in process more reasonable, clamping stability and reliability better, effectively improve major axis crudy, product line fraction defective is down to minimum, and this clamp structure is simple, dismounting is extremely convenient, time saving and energy saving, effectively improve production efficiency, create higher economic benefit.Therefore, there is very wide application prospect and promotional value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the major axis special fixture that the utility model provides.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, further detailed complete to illustrate is done to the utility model.
