Abstract
A fast cutting tool detaching mechanism for borer features that a guide sleeve with an axial long slot is installed to the front end of mainshaft to make it be fit with the boring rod with very small gap, a slide sleeve is arranged around the guide sleeve, and a pin is fixed to the slide sleeve in such manner that it passes through said long slot on guide sleeve and the tool detaching slot on boring rod. When the borning rod is withdrawn, the pin can quickly detach the cutting tool.
Description
The present invention relates to the cutter disassembling machine structure of Metal Cutting Machine Tool, the cutter disassembling machine structure of especially common horizontal boring machine.
In the present common horizontal boring machine main shaft movably boring bar is arranged, on the boring bar structure of mounting cutter be the taper hole that matches with tool shank and taper hole rear portion radially connect main shaft unload the cutter groove.Taper hole mainly plays the centering effect that cutter is installed.The cutter groove that unloads that radially connects main shaft matches with the tang of cutter, rises and transmits torsional interaction.Available dedicated contract iron inserts and unloads in the cutter groove simultaneously, utilizes the inclined-plane of contract iron to withstand the tang rear end, and cutter is unloaded.When on boring machine, processing bulk of components, when needing frequently the loading and unloading cutter.Unloading cutter with contract iron extremely bothers: unloading the cutter groove and must be able to insert contract iron the position of conveniently unloading cutter when 1, unloading cutter on the main shaft.And the main shaft stopping time, the position of unloading the cutter groove on it is at random, generally rotating spindle just can make the position of unloading the cutter groove be fit to unload cutter again; Will catch contract iron on the other hand when 2, unloading cutter, the another hand knocks contract iron with hammer, behind the pine of cutter top, puts down contract iron or hammer in the hand, and cutter is taken down.The whole cutter process of unloading is cumbersome, and the long and main shaft of damaging easily of holding time influences its precision.As overexert, cutter is fallen down, damage machine tool guideway or damage cutter.
The objective of the invention is to overcome the defective of prior art, a kind of quick cutter disassembling machine structure is provided, make and unload cutter safety again fast.
The objective of the invention is to realize as follows: the front end at boring spindle installs and fixes a guide pin bushing, and making itself and the boring bar of boring machine is very little the cooperating in gap.One elongated slot that axially connects is arranged on the guide pin bushing.Guide pin bushing is equipped with the sliding sleeve that is slidingly matched with it outward, installs and fixes one in the appropriate location of sliding sleeve and passes the pin that elongated slot and boring bar on the guide pin bushing unload the cutter groove.When rotating lathe boring bar advance and retreat handle, when boring bar was drawn back, pin withstood cutter tang rear end, fast cutter is unloaded.
The advantage of the quick cutter disassembling machine structure of this boring machine is: utilize lathe boring bar advance and retreat handle, finish the cutter work of unloading when boring bar retreats.Unloading the cutter action just can carry out when main shaft does not stop fully.Can a hand turning handle boring bar is retreated cutter is unloaded, the another hand be taken the cutter that is removed simultaneously, therefore unload cutter safety, fast, reliable.Owing to increased guide pin bushing, prolonged the bearing length of boring bar, strengthened the rigidity of boring bar greatly, very favourable to process.Be specially adapted to boring machine and process workpiece in enormous quantities, need the frequent situation of changing cutter.
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing is the cross section view that passes through boring bar axial line and pin axial line of the quick cutter disassembling machine structure of boring machine of the present invention.Accompanying drawing 1 is that the boring spindle front end is the installation diagram of the cutter disassembling machine structure of facing head, and accompanying drawing 2 is installation diagrams that the boring spindle front end does not have the cutter disassembling machine structure of facing head.
With reference to accompanying drawing 1, the boring spindle front end is the cutter disassembling machine structure of facing head: the cylindrical and the end face of cover 2 usefulness its rear end cooperate with boring spindle facing head 1, are fixed on the facing head 1 with T-slot bolt 16, plain washer 15, spring washer 14, nut 13.The endoporus of guide pin bushing 2 and the boring bar of boring machine 5 fit clearances are the 0.005-0.015 millimeter.The elongated slot that radially connects is arranged in the appropriate location of guide pin bushing 2.The sliding sleeve 3 that is slidingly matched with it is housed outside guide pin bushing 2, and pin 4 is contained in and passes through on the sliding sleeve 3 to be fixed on the sliding sleeve 3 with packing ring 10, spring washer 11, screw 12 in the radial hole of its axial line.Pin 4 can be free to slide in the elongated slot that unloads guide groove, guide pin bushing 2 of boring bar 5.The front end of sliding sleeve 3 is equipped with the rubber ring 6 that is used to seal boring bar 5, with screw 8 and cover plate 7 rubber ring 6 is fixed on the sliding sleeve 3.When the corresponding handle that shakes lathe retreated boring bar 5, pin 4 just can eject the cutter 9 that is contained in the boring bar taper hole.Make and unload cutter process safety, quick, reliable.
With reference to accompanying drawing 2, the cutter disassembling machine structure that the boring spindle front end the does not have a facing head fixedly method of guide pin bushing 2 is: hole of guide pin bushing 2 usefulness its rear end and inner face match with boring spindle front end cylindrical, end face, with bolt 18, plain washer 15, spring washer 14, be fixed in main shaft 17.Other structures and boring machine front end are that the cutter disassembling machine structure of facing head is the same.
