Description
Technical field
The utility model relates to the metal cutting machine technical field, and specifically a kind of metal cutting machine is used the cutter automatic tool retracting unit.
Background technology
At present, the cutter tool retracting device of the workpiece that is used on the planer to plane has two kinds usually, and a kind of is the manual type withdrawing, and another kind is mechanical automatic tool retracting unit; The manual type withdrawing is that cutter does reciprocating linear motion on lathe bed along ram with knife rest; When backstroke,, realize the cutter lifting action near the inertia and the corresponding member that continues of drawback movement because automatic tool retracting unit is not set; Existing work piece surface is prone to pulled and reduce precision by planing tool; And the wearing and tearing of planing tool major cutting edge are very fast, pulled by planing tool in order to reduce because of the planing tool surface, utilize manual type to carry out the cutter lifting withdrawing usually; Increased operator's labour intensity virtually, and crudy can not guarantee; The machinery automatic tool retracting unit is made up of ram, tool-post structure, rocking arm, ratchet mechanism, rotating shaft and electromagnetic driver, and electromagnetic driver is made up of electromagnet winding, power supply and microswitch, and the electromagnet core in the electromagnetic driver is fastened on the cutter fluctuating seat of tool-post structure; Convex edge on the crankwheel is the circular ring plate that is fastened on the wheel rim periphery, and circular ring plate curved arc institute is 175 ° to central angle, when crankwheel rotates; Ram, knife rest are done in the half cycle of auto-feed campaign, and the microswitch disconnection, the electromagnet that are installed on the hub do not attract armature, and planing tool is done the feeding cutting in as-machined workpiece surface; After the auto-feed campaign finished, after crankwheel turned over half cycle, microswitch push-button was depressed in the convex edge on it; Energized and electromagnet coil are because armature by adhesive, makes planing tool lift certain angle around axle through armed lever; Leave the workpiece to be machined surface, finish until backhaul, after the convex edge at 175 ° of angles turns over microswitch; Electromagnet winding and power supply break off, and planing tool leans on from repeats bits, and its advantage is to have improved machining accuracy; Alleviated the wearing and tearing of planing tool, its deficiency is that planing tool knife bar stroke is little, and the processing work scope is little.
Summary of the invention
The purpose of the utility model is the deficiency that solves above-mentioned prior art, provide a kind of rational in infrastructure, easy to operate, the knife bar stroke big, enlarge the range of work, working (machining) efficiency is high, labour intensity is low metal cutting machine is used the cutter automatic tool retracting unit.
The utility model solves the technical scheme that its technical problem adopted:
A kind of metal cutting machine is used the cutter automatic tool retracting unit, is provided with ram, rotating shaft, knife bar and tool-post structure, it is characterized in that ram one side is provided with positioning seat; The knife bar upper end is fixedly connected with positioning seat, and the lower end is hinged through rotating shaft and tool-post structure, and tool-post structure is made up of cutter fluctuating seat, cutter head and tensioning spring; Cutter rises and falls, and the seat upper end is middle to be provided with positioning boss, and a side and knife bar are inconsistent, and tensioning spring and the knife bar lower end of opposite side in the tensioning spring locating hole that is provided with is inconsistent; Be beneficial to add man-hour, tool-post structure drives the cutter autofeed, during the completion of processing withdrawing; Because the effect of tensioning spring, cutter is only kept pressure seldom to surface of the work, to guarantee cutter safety withdrawing; And do not damage on the finished surface, reach the effect that easy to operate, knife bar stroke is big, enlarge the range of work.
The utility model can be provided with lubrication channel in rotating shaft, be beneficial to the lubricated of countershaft, and cutter fluctuating seat rotates effect flexibly when reaching the cutter head withdrawing.
The utility model has rational in infrastructure, easy to operate, advantages such as the knife bar stroke big, the expansion range of work, working (machining) efficiency is high, labour intensity is low owing to adopt said structure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model tool-post structure.
Reference numeral: ram 1, rotating shaft 2, knife bar 3, positioning seat 4, cutter fluctuating seat 5, cutter head 6, tensioning spring 7, positioning boss 8.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Shown in accompanying drawing, a kind of metal cutting machine is used the cutter automatic tool retracting unit, is provided with ram 1, rotating shaft 2, knife bar 3 and tool-post structure; It is characterized in that ram 1 one sides are provided with positioning seat 4, knife bar 3 upper ends are fixedly connected with positioning seat 4, and the lower end is hinged through rotating shaft 2 and tool-post structure; Tool-post structure is made up of rise and fall seat 5, cutter head 6 and tensioning spring 7 of cutter, cutter rise and fall seat 5 upper ends middle be provided with positioning boss 8, one sides and knife bar 3 inconsistent; The tensioning spring 7 of opposite side in the tensioning spring locating hole that is provided with is inconsistent with knife bar 3 lower ends, is beneficial to add man-hour, and tool-post structure drives the cutter autofeed; During the completion of processing withdrawing; Because the effect of tensioning spring 7, cutter is only kept pressure seldom to surface of the work, to guarantee cutter safety withdrawing; And do not damage on the finished surface, reach the effect that easy to operate, knife bar stroke is big, enlarge the range of work.
The utility model can be provided with lubrication channel in rotating shaft, be beneficial to the lubricated of countershaft, and cutter fluctuating seat rotates effect flexibly when reaching the cutter head withdrawing.
Cutter in the utility model under free state because gravity and the effect of tensioning spring tension force, cutter rise and fall seat 5 and knife bar 3 tightly near; Knife bar 3 drive cutters rise and fall seat 5, when cutter head 6 moves downward through ram 1, cutter head 6 cuts, and workpiece is processed; Completion of processing, knife bar 3 drive cutter fluctuating seat 5, cutter head 6 moves upward, the tension force effect of the tensioning spring 7 of cutter head 6 between cutter fluctuating seat 5 and knife bar 3; Cutter head 6 back sides are contacted with the workpiece machined surface, and cutter head 6 back sides only need overcome the effect of spring and gravity, and this part pressure is very little; Therefore can guarantee that cutter head 6 is under the situation of not damaging surface of the work; Safety withdraws from, and to process next time, reaches the effect that the workpiece machining accuracy is high, working (machining) efficiency is big, labour intensity is low.
The utility model has rational in infrastructure, easy to operate, advantages such as the knife bar stroke big, the expansion range of work, working (machining) efficiency is high, labour intensity is low owing to adopt said structure.The utility model can be used on slotting machine or the planer.
