Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model detailed description of the invention is described:
Embodiment, see accompanying drawing 1, a kind of high-speed milling principal shaft locking locking gear, comprise main shaft 1, disk spring 2, pull bar 3, sliding sleeve 4, steel ball 5, pulling claw 6, handle of a knife 7, stop nut seat 8 and backing-up screw 9, it is characterized in that, described main shaft 1 right-hand member center is a cone-shaped inner hole, described handle of a knife 7 right-hand member is fixedly mounted in cutter left end centre bore by screw thread, described handle of a knife 7 left end is stuck in pulling claw 6 left end centre bore, described sliding sleeve 4 to be arranged in the middle part of main shaft 1 in cylindrical hole and with main shaft 1 endoporus matched in clearance, described sliding sleeve 4 right-hand member has an annular recess, described sliding sleeve 4 groove is stuck in pulling claw 6 left end centre bore, described stop nut seat 8 is fixedly mounted in the axial hole of sliding sleeve 4 center, described backing-up screw 9 is arranged in stop nut seat 8 internal thread hole, described backing-up screw 9 left end withstands on steel ball 5 outer surface, described steel ball 5 is stuck in pull bar 3 right-hand member taper hole, described pull bar 3 is arranged in the left end shaft inward hole of main shaft 1 center and its right-hand member is connected with sliding sleeve 4 left end by screw thread, between described pull bar 3 left end external cylindrical surface and main shaft 1 left end endoporus, disk spring 2 is installed, described disk spring 2 right-hand member is located by main shaft 1 left end endoporus step.
In connection transition piece sliding sleeve 4 between described pull bar 3 and pulling claw 6, increase steel ball 5, backing-up screw 9, stop nut seat 8; Sliding sleeve 4 and pull bar 3 adopt and are threaded; There are a taper hole and the tangent cooperation of steel ball 5 in pull bar 3 axle head inside, the axial force produced when being tightened by backing-up screw 9 promotes steel ball 5, this power indirectly-acting makes it to periphery uniform expansion in pull bar 3 internal taper hole, thus makes pull bar 3 and the distortion of sliding sleeve 4 connecting thread, allows connecting thread tooth evenly be engaged; When metal cutting process, under disk spring 2 acts on, pull bar 3 drives sliding sleeve 4 up to move, and pulls pulling claw 6 by handle of a knife 7 axial tightening, along with main shaft 1 High Rotation Speed cuts, even if handle of a knife 7 all can not come off when positive and negative rotation machining.
By reference to the accompanying drawings the utility model preferred embodiment is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
Locking locking gear is on locking syndeton basis, increase by backing-up screw, steel ball and and the steel ball effect taper hole that forms phase tangent line jointly form.Its working mechanism is: when adjustment backing-up screw after, screw axial feeding, promote steel ball by active force uniform load on steel ball and taper hole tangent circle. this similar is in power, displacement amplifier.I.e. force-increasing mechanism. will the distributed force that size is identical, tangent circle normal is passed through in direction be produced, make axle head outwards evenly finite deformation, and then locking screw circumference is closely engaged, and reduces thread pitch, reaches locking object.
