Description
Technical field
The present invention relates to machined field, particularly relate to a kind of Manual auxiliary support mechanism that elongated workpiece is processed.
Background technology
In part process, if in operation, the cutting force of process tool is large (as workpiece rough mill plane operation), part to be processed length is grown again (as the rear axle housing body of engine cylinder-body, cylinder cap, automobile), in process, workpiece very easily produces deflection deformation so, this deflection deformation often causes the non-constant of flatness precision of the workpiece planarization that machines, can directly cause the workpiece of processing defective.
Conventional solution is to increase auxiliary support mechanism on workpiece support face now, for the fixture that has hydraulic system, the general supplemental support unit that increases fluid pressure type, but the workpiece of producing for small lot processing, trial-production, what often adopt is manual, manual non-hydraulic system, and the supplemental support unit of fluid pressure type just cannot be used, and the supplemental support of fluid pressure type is expensive.So a lot of processing factories daily life of a family solves the deflection deformation in small batch workpiece process with increasing rigid support point, but there are following two problems:
1. the support force of rigidity supplemental support point is larger, and the size of power cannot regulate, bad for the deflection deformation effect reducing in workpiece process like this, can not guarantee that the flatness of processing work is qualified;
2., if processing work blank supporting plane height exists deviation, the whole height that must readjust rigidity supplemental support point of every processing, wastes time and energy.
Summary of the invention
The object of the embodiment of the present invention is to provide a kind of Manual auxiliary support mechanism, can automatically regulate supplemental support power, automatically adapt to the height error of the supporting plane of blank workpiece, solved rigidity supplemental support point and adjusted the problem that inconvenience is wasted time and energy, and avoided because cutting force changes the vibration problem of the supplemental support point causing.

The top view of the bearing that Fig. 9 provides for the embodiment of the present invention, Figure 10 be in Fig. 9 D-D to cutaway view.As shown in Fig. 9 Figure 10, bearing has the first screwed hole 181 matching with lock-screw 16, and the second screwed hole 182 matching with the second lock-screw 17.
The part using in the embodiment of the present invention is except trip bolt, pin 22, lock-screw 16, lock-screw 17, spring 19 and the nut 13 of national standard, and other each part is parts peculiar, is special designs and making.
In the process of workpiece 11, the deflection deformation producing because of cutting force in order to reduce workpiece 11, Manual auxiliary support mechanism is arranged on clamp body 20, by spring 19, adjust the size of height and the support force of support column 14, the height of support column 14 will be higher than the supporting plane of workpiece 11, after workpiece 11 is fallen in workpiece support plane, support column 14 is under the effect of spring 19 elastic forces, give 11 1 support forces that make progress of workpiece, this support force can be offset the cutting force of part cutter, make workpiece stress balance, reduce the deflection deformation of workpiece 11 in process, thereby guarantee the machining accuracy of workpiece 11.
It should be noted that, after workpiece 11 is fallen in workpiece support plane, roller 12 on support column 14 contacts with workpiece bottom, under the effect of spring 19, give 11 1 support forces that make progress of workpiece, but in workpiece process, variation due to Tool in Cutting power size, can cause that support column 14 fluctuates, cause Workpiece vibration, finally affect workpiece 11 machining accuracies, so after falling in workpiece support plane when workpiece 11, workpiece 11 first being processed, need to adjust lock-screw 16, locking support post 14, prevents that support column 14 from fluctuating.
In embodiments of the present invention, guide pin bushing 15 interference fit are arranged on bearing 18, with lock-screw 17 lockings, roller 12 use pins 22 are connected on support column 14, support column 14 is connected with push rod 21 matched in clearance, then, by spring 19, push rod 21 installations, finally total is arranged on clamp body 20 with screw, before formal processing, adjust the height of support column 14, just can process.
Visible, be different from traditional rigidity supplemental support, the size of support force of the present invention can be adjusted by adjusting the size of spring force, and for blank supporting plane height, has the workpiece of deviation, does not need frequently to adjust the height of the strong point.Can adjust the size of supplemental support power and the height of elasticity supplemental support point by changing the height of spring 19.
As from the foregoing, the embodiment of the present invention has following advantage:
1) for different blank workpiece, even if there is deviation in the supporting plane height of workpiece, also need not adjust bearing 18 and clamp body 20, spring is understood automatic telescopic to adapt to the height of supporting plane when supplemental support power is provided, therefore after changing blank workpiece, greatly reduced the adjustment time of supplemental support point.
2) after the supporting plane height of spring self-adapting blank workpiece, by lock-screw 16 locking push rods 21, prevent from because of the variation of cutting force, causing in working angles the vibration of supplemental support point, can better ensure machining accuracy.
3) supplemental support point contacts with workpiece 11 by roller 12, when being installed, elongated workpiece can directly promote on the roller of supplemental support point, in process, when elongated workpiece produces axial deformation because of cutting force or because of expanding with heat and contract with cold, roller can this distortion of self adaptation, avoids scratching the workpiece of processing.
4) volume of Manual auxiliary support of the present invention mechanism is little, easy to install, and cost is low, effective.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
