Set hydraulic pressure automatic locking mechanism 38, be to be equipped with on the right side of saddle 9 with saddle 9 is fixedly connected by screw to place base 40 on the body of lathe bed 39, in the central vertical elongated circular hole of base 40, be equipped with by cylinder head 41, cylinder body 42, cylinder cap 43, piston 44, what piston rod 45 constituted fixes with base 40, and the hydraulic cylinder 46 that is connected with the oil circuit of traverse feed hydraulic cylinder 13, the bottom of its piston rod 45 is fixedly connected with pyramidal locking member 47, in other two corresponding vertical elongated circular holes on base 40, the inboard that respectively is equipped with its bottom of " L " type that is connected with base by bearing pin 48 and bearing pin 49 places locking member 47 both sides and corresponding jaw 50 and jaw 51, the end of two jaw bottom inside, connect respectively between the screw that has on

roller

52 and 53, two jaws of roller by bearing pin and to be connected with extension spring 54.

When utilizing the utility model Milling Process lenticular shaped riffled roll, after starting lathe, the rotation of lathe chuck 1 and splined shaft 2 drives transmission and milling mechanism work, milling is carried out in milling cutter 7 revolutions on roll, its feed is to drive milling mechanism by transverse feed mechanism to do traverse feed, milling cutter 7 feeds meet the requirements of increased pressure after the degree of depth, 13 automatic reverses of traverse feed hydraulic cylinder, and milling cutter 7 returns to original position.In the time of the milling cutter withdrawing, the hydraulic cylinder 16 of vertical intermittent feeding mechanism drives clamp 18 fast moving to the left by piston rod wherein, this moment, clamp 18 slided on the inclined-plane of sour jujube bar 17, after moving a pitch, milling cutter 7 also just in time withdrawing finish, the travel switch that is equipped with on the feeding slide block 12 of transverse feed mechanism touches the contact at this moment, send signal, make 13 commutations of traverse feed hydraulic cylinder, hydraulic cylinder 16 drives pitch of knife rest 8 fast moving simultaneously, because the sequence valve of Hydraulic Station makes traverse feed hydraulic cylinder 13 begin oil-feeds, feeding slide block 12 is moved to left on roll, carry out the milling of next lenticular shaped groove, behind the intact row's groove of roll milling, rotate the handle 22 of longitudinal feed mechanism, clamp 18 cards are moved break away from sour jujube bar 17, utilize fast moving handle 15 to make knife rest 8 move to the original position of first groove of left side again, use precision round subsection mechanism 25 to carry out calibration.

When using precision round subsection mechanism 25 to carry out calibration, rotate rotary handle 29 earlier, the gear 36 that the rotation drive of rotating shaft 34 is meshed and the rotation of gear 35, and then the rotation of drive dividing gear 28, dividing gear 27 and worm screw 32, the rotation of final worm gear 26 impels roll 24 to turn round on slotting roller 23, the number of divisions that needs calibration is to realize by the number of teeth that changes dividing gear 28, when dividing gear 28 rotates the integer circle, calibration Fixed latches 37 is inserted in the circular hole of dividing gear 28 and fixed base plate, be fixed.Owing to adopt gear compound graduation, improved indexing accuracy, and owing to have only a hole on the fixed base plate, dividing gear 28 rotates the integer circle again, calibration Fixed latches 37 jacks are wanted a wrong just wrong circle fixedly the time, at this moment the milling cutter position detects by an unaided eye and very easily finds, just with correction, so calibration is accurate, can avoid fully because of the indexing operation mistake cause processed after roll quality problems appear, or even waste product appears, and guaranteed crudy, improved working (machining) efficiency.

When using original processing riffled roll device Milling Process rollet roll, milling cutter is fragile, roll is vulnerable to damage, to cause processed roll to become waste product when serious, because when Milling Process, milling cutter axis and roll axis are 45, and be again to be interrupted milling, produced and be interrupted the axial force that changes, made milling cutter produce side-to-side vibrations, influenced Milling Process amount and machining accuracy, the particularly easier damage of milling cutter under the stubbed situation of milling cutter, axial force strengthens when forging a knife, and moves axially and vertically the sour jujube bar of intermittent feeding mechanism can only unidirectional control milling cutter, causes one to damage milling cutter and will damage roll.The utility model just can have been avoided the generation of the problems referred to above fully owing to be provided with the hydraulic pressure automatic locking mechanism.

The hydraulic pressure automatic locking mechanism 38 that the utility model is provided with, because the sequence valve of Hydraulic Station makes traverse feed hydraulic cylinder 13 begin oil-feeds, when feeding slide block 12 moves to left, milling cutter carries out in the milling on roll, hydraulic oil in the traverse feed hydraulic cylinder 13 enters in the hydraulic cylinder 46 of hydraulic pressure automatic locking mechanism by pipeline road again, the increase of the interior oil pressure of cylinder promotes its piston 44 and piston rod 45 moves down, jaw 50 and jaw 51 that the cone-shaped locking member 47 of piston rod 45 bottoms just promotes its both sides laterally rotate, making it two jaws tightly blocks mutually with the body of lathe bed 39, making it whole hydraulic pressure automatic locking mechanism is fixed firmly, and then the knife rest 8 that makes it to be fixedly connected indirectly with the hydraulic pressure automatic locking mechanism firmly fixed, and finally reaches to make the milling cutter can not side-to-side vibrations, improve the purpose of Milling Process amount and assurance crudy.Otherwise during withdrawing, two jaws unclamp, and can carry out vertically intermittently moving.
