Description
Technical field
The present invention relates to metal cutting machine technical field, specifically a kind of automatic tool retracting unit for metal cutting machine tool.
Background technology
At present, the cutter tool retracting device for workpiece of planing on planer has two kinds usually, and one is manual type withdrawing, and another kind is machine automatization tool retracting device, manual type withdrawing and cutter do reciprocating linear motion along ram with knife rest on lathe bed, when backstroke, owing to not arranging automatic tool retracting unit, inertia near drawback movement realizes cutter lifting action with the corresponding component that continues, there is work piece surface easily pulled by planing tool and reduce precision, and the wearing and tearing of planing tool major cutting edge are very fast, in order to reduce because planing tool surface is pulled by planing tool, usually manual type is utilized to carry out cutter lifting withdrawing, virtually add the labour intensity of operator, and crudy can not ensure, machine automatization tool retracting device is by ram, tool-post structure, rocking arm, ratchet mechanism, rotating shaft and electromagnetic driver composition, electromagnetic driver is by electromagnet winding, power supply and microswitch composition, electromagnet core in electromagnetic driver is fastened on the cutter fluctuating seat of tool-post structure, convex edge on crankwheel is the circular ring plate being fastened on wheel rim periphery, circular ring plate curved arc institute is 175 ° to central angle, when crankwheel rotates, make ram, knife rest does in the half cycle of auto-feed campaign, the microswitch be arranged on hub disconnects, electromagnet does not attract armature, planing tool is done feeding in as-machined workpiece surface and is cut, after auto-feed campaign terminates, after crankwheel turns over half cycle, convex edge pressure microswitch push-button on it, switch on power and electromagnet coil, because armature is by adhesive, planing tool is made to lift certain angle around axle by armed lever, leave workpiece to be machined surface, until backhaul terminates, after the convex edge at 175 ° of angles turns over microswitch, electromagnet winding and power supply disconnect, planing tool is by self-weight reset, its advantage improves machining accuracy, alleviate the wearing and tearing of planing tool, its deficiency is that planing tool knife bar stroke is little, processing work scope is little.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure, easy to operate, knife bar stroke large, expand the range of work, working (machining) efficiency is high, labour intensity is low automatic tool retracting unit for metal cutting machine tool.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of automatic tool retracting unit for metal cutting machine tool, be provided with ram, rotating shaft, knife bar and tool-post structure, it is characterized in that ram side is provided with positioning seat, knife bar upper end is fixedly connected with positioning seat, lower end is hinged through rotating shaft and tool-post structure, tool-post structure to be risen and fallen seat by cutter, cutter head and tensioning spring composition, positioning boss is provided with in the middle of cutter fluctuating seat upper end, side and knife bar inconsistent, tensioning spring in the tensioning spring locating hole of opposite side through being provided with and knife bar lower end inconsistent, be beneficial to add man-hour, tool-post structure carry its tools autofeed, during completion of processing withdrawing, due to the effect of tensioning spring, cutter only maintains little pressure to surface of the work, to ensure the safe withdrawing of cutter, and do not damage on finished surface, reach easy to operate, knife bar stroke is large, expand the effect of the range of work.
The present invention can be provided with lubrication channel in rotating shaft, is beneficial to the lubrication of countershaft, and when reaching cutter head withdrawing, cutter fluctuating seat rotates and acts on flexibly.
The present invention, owing to adopting said structure, has the advantages such as rational in infrastructure, easy to operate, knife bar stroke large, expand the range of work, working (machining) efficiency is high, labour intensity is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of tool-post structure of the present invention.
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.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of automatic tool retracting unit for metal cutting machine tool, be provided with ram 1, rotating shaft 2, knife bar 3 and tool-post structure, it is characterized in that ram 1 side is provided with positioning seat 4, knife bar 3 upper end is fixedly connected with positioning seat 4, lower end is hinged through rotating shaft 2 and tool-post structure, tool-post structure is by cutter fluctuating seat 5, cutter head 6 and tensioning spring 7 form, positioning boss 8 is provided with in the middle of cutter fluctuating seat 5 upper end, side and knife bar 3 inconsistent, tensioning spring 7 in the tensioning spring locating hole of opposite side through being provided with is inconsistent with knife bar 3 lower end, be beneficial to add man-hour, tool-post structure carry its tools autofeed, during completion of processing withdrawing, due to the effect of tensioning spring 7, cutter only maintains little pressure to surface of the work, to ensure the safe withdrawing of cutter, and do not damage on finished surface, reach easy to operate, knife bar stroke is large, expand the effect of the range of work.
The present invention can be provided with lubrication channel in rotating shaft, is beneficial to the lubrication of countershaft, and when reaching cutter head withdrawing, cutter fluctuating seat rotates and acts on flexibly.
Cutter in the present invention in a free state, due to gravity and the effect of tensioning spring tension force, cutter fluctuating seat 5 is tightly close with knife bar 3, knife bar 3 carry its tools fluctuating seat 5, when cutter head 6 is moved downward by ram 1, cutter head 6 cuts, workpiece is processed, completion of processing, knife bar 3 carry its tools fluctuating seat 5, cutter head 6 moves upward, cutter head 6 is through the tension force effect of the tensioning spring 7 between cutter fluctuating seat 5 and knife bar 3, cutter head 6 back side is contacted with work pieces process face, cutter head 6 back side only needs the effect overcoming spring and gravity, and this part pressure is very little, therefore can ensure that cutter head 6 is when not disfiguring workpiece surface, Safe withdrawing, to process next time, reach Workpiece Machining Accuracy high, working (machining) efficiency is large, the effect that labour intensity is low.
The present invention, owing to adopting said structure, has the advantages such as rational in infrastructure, easy to operate, knife bar stroke large, expand the range of work, working (machining) efficiency is high, labour intensity is low.The present invention can be used on slotting machine or planer.
