Description
Technical field
The present invention relates to end mill equipment auxiliary technical field, be specifically related to a kind of end mill cutter quick change construction.
Background technology
Existing end mill equipment cutter uses nut check on cutter shaft, in the time of tool changing, need to use two spanners, bothersome effort, and while carrying out tool changing operation, the positional distance cutter blade of hand is very near, and careless slightly just have the situation of hindering hand to occur, and operating personnel's personal safety is caused to certain threat.
Summary of the invention
The invention provides a kind of end mill cutter quick change construction, the problem that tool changing is wasted time and energy He easily the personnel that cause injure existing to solve prior art.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of end mill cutter quick change construction, mainly by cylinder, pull bar, casing, main shaft, synchronous pulley, Timing Belt, hold-down mechanism and gang tool composition, cylinder is fixed on cylinder block, cylinder head connects a jacking block, pull bar is positioned at cylinder top, the tail end of pull bar is fixed a spring capping, spring capping is by spring compression in the space between spring capping and main shaft, lower bearing gland is pressed on two bearings in the installing hole processing in casing, pull bar, main shaft, synchronous pulley and Timing Belt are all installed on box house, locknut is pressed on two angular contact bearings on main shaft, upper bearing (metal) gland is pressed on angular contact bearing in the installing hole processing in casing, synchronous pulley is connected with holding screw by key bar and is fixed on main shaft, hold-down mechanism comprises compact heap and compact heap axle, compact heap is connected to pull bar top by compact heap axle, compact heap axle is embedded in the installing hole that pull bar top processes, Timing Belt one end is connected on synchronous pulley, the Timing Belt other end is connected in external motor, gang tool is fixed on main shaft by hold-down mechanism.
A dust cover is installed at above-mentioned casing top, to prevent that machining chips from entering in the space of synchronous pulley and bearing.
Combinations thereof tool sharpening has the mating groove matching with compact heap.
Above-mentioned pull bar and spindle processing have the groove matching with compact heap.
Cylinder block is connected by screw and fixes cylinder, and on the predetermined installation site of the equipment that is fixed by screws in, for preventing misoperation, generally be arranged on head backhaul initial point under, slide away and add man-hour at whole head like this, even if there is misoperation and also can not push up below spring capping, can not cause cutter to get loose in cylinder.
In the time that needs are changed cutter, device powers down, under the condition that motor stops operating, head is positioned at backhaul initial point, at this moment give and make cylinder action by button or switch, upwards release cylinder rod, make jacking block contact also pushing drawing rod with spring capping and move upward, now compact heap can movablely in the mating groove of pull bar and main shaft and gang tool processing also rotate, and gang tool can take out from main shaft very easily.After new gang tool is placed on main shaft, compact heap is movable and rotation again, X button or switch make cylinder action, pull down air return cylinder bar, make jacking block and spring capping depart from and stand away, spring capping and pull bar move downward under the effect of spring, pull compact heap and make in its mating groove that is fixed on pull bar and main shaft and gang tool processing.So just, cutter is fixed on main shaft, and has prevented that the problem of rotation from appearring in gang tool with respect to main shaft.At this moment just can start motor processing, under the effect that is rotated in Timing Belt of motor, drive 15, synchronous pulley, by key bar and the rotation of holding screw interlock main shaft, under the effect of compact heap, drive tool sharpening.
The beneficial effect of apparatus of the present invention is:
1, simple in structure, cost is low
2, convenient to operation
3, fundamentally improved the processing safety of tool changing.
