Relative slide occurs for the axial direction of the first cutter groove.
By using above-mentioned technical proposal, using the internal thread of installed part endoporus with treating that the fastener external screw thread of grooving coordinates
So that fastener obtain in the axial direction it is spacing, after installed part is connected in mounting groove, some blade meetings in mounting groove
It is inserted into the first cutter groove that mounting groove is opened up, finally installed part, which is exerted a force, using drive mechanism causes installed part slowly to knife
The lateral movement of piece one, realize to externally threaded grooving operations, and correspondingly set according to grooving position, grooving quantity and cutting groove depth
The length of blade position in mounting groove, knife number and blade is put, the grooving operations of different requirements can be achieved；Secondly can one
Secondary performance completes the operation to a plurality of grooving, improves processing efficiency.
Preferably, the blade plate is further opened with stopper slot, and the stopper slot includes connecting and being used for mounting groove
The cutter head groove for housing the second cutter groove of blade and being connected with the second cutter groove, the end of the blade, which is additionally provided with, can be placed in knife
Cutter head in head groove, the maximum gauge of wherein cutter head are greater than the thickness of blade.
By using above-mentioned technical proposal, blade can be contained in the second cutter groove of blade plate, and utilizes blade end institute
The cutter head of setting be contained in cutter head groove so that blade obtain in the horizontal direction it is spacing, as long as and lower end on blade axial direction
Be connected to arbitrary plane upper limit axially downwardly displacement can grooving work, such set facilitate the dismounting of blade, be applied to
Different grooving requirements.
Preferably, the fixture also includes pressing plate and the fixation for being individually fixed in blade plate upper surface and lower surface
Plate, the blade and cutter head are pressed between pressing plate and fixed plate；The pressing plate and fixed plate correspond to the position of mounting groove
Put the first resigning hole and the second resigning hole for offering and being connected with mounting groove.
By using above-mentioned technical proposal, the setting of pressing plate and fixed plate is spacing in the axial direction with cutter head by blade first；
Secondly the first resigning hole effect positioning hole opened up on pressing plate facilitates installed part through snapping onto in mounting groove, institute in fixed plate
The second resigning hole opened up improves axially directed property of the installed part in displacement process, improves the essence of grooving as guide effect
Degree.
Preferably, first resigning hole, the second resigning hole are identical with the shape and size of mounting groove.
By using above-mentioned technical proposal, the depth of the first resigning hole and the second resigning hole intensification mounting groove, installation is improved
Guidance quality of the part when being subjected to displacement, and then improve the precision of grooving.
Preferably, in addition to an ejecting mechanism, the ejecting mechanism are connected to the second resigning hole including partial slip
In support base and located at support base bottom and the elasticity that forces support base upper surface to be abutted all the time with the lower surface of installed part
Part.
By using above-mentioned technical proposal, support base synchronous shift can be promoted when installed part is subjected to displacement in blade plate,
So that being connected to the elastic component compression storage elastic potential energy of support base lower surface, after grooving operations are completed, drive mechanism is removed
Driving force support base can reset in the presence of the elastic component and promote installed part slowly eject in the mounting groove from blade plate, it is convenient
Installed part is taken out, improves processing efficiency.
Preferably, the fixture also includes backing plate and bottom plate, and the backing plate is fixed on the lower section of fixed plate, bottom plate
It is fixed on the lower section of backing plate, the backing plate and bottom plate are offered for support base guide groove in axial sliding；The ejecting mechanism is also
Including upper limit plate and lower limiting board, the elastic component is located between upper and lower limiting plate, the end abutment of the support base in
Upper limit plate, wherein upper and lower limiting plate is located at the lower section of bottom plate, the upper limit plate and lower limiting board by some connectors
Axial displacement can occur along connector.
By using above-mentioned technical proposal, the guide groove mating part that is opened up on backing plate slides on fixed plate second and stepped down
The support base in hole preferably improves the guidance quality of whole support base；The upper and lower limiting plate being connected secondly by connector with bottom plate
Elastic component is spacing, and acting on upper limit plate using support base makes its opposite joints that axial displacement compression elastic piece or logical occur
Cross elastic component release elastic potential energy and act on the promotion support base reset operation of upper limit plate.
Preferably, the connector is screw rod, and the threaded one end of the screw rod is connected on bottom plate, other end screw thread
It is connected with adjusting nut.
By using above-mentioned technical proposal, connection fixing is improved using the thread connecting mode of screw rod and bottom plate, and
It can be increased with the decrement of regulation elasticity part or reduce the elastic force suffered by support base, it is ensured that tight using adjusting nut
Grooving is processed on firmware external screw thread, is avoided due to the too small effect for having influence on grooving of installed part bottom support force.
Preferably, be additionally provided with support block in the endoporus, the upper surface of the support block and the side wall of endoporus it
Between form a hole shoulder.
By using above-mentioned technical proposal, after fastener threads are connected to installed part, bottom can be connected to the support of endoporus
Position-limiting action can be played on block first；Secondly can guarantee that when fastener is driven with installed part the driving force that mechanism applied
Installed part and fastener synchronizing moving, avoid fastener that axially opposite movement occurs with installed part.
Preferably, the drive mechanism includes drift and hydraulic cylinder, and the piston rod of the drift and hydraulic cylinder connects
Connect.
By using above-mentioned technical proposal, it is applied to using the hydraulic coupling of hydraulic cylinder by piston rod on drift, drift exists
Effect promotes installed part to realize grooving operations in generation axial movement in mounting groove on mountings, using hydraulic coupling with respect to other
Driving force has power big, drives stable effect, it is ensured that the stable progress of grooving operations.
Two purposes of the present invention are to provide the method for external screw thread axial direction grooving a kind of, can once property is cut out on external screw thread
The grooving of requirement, improve processing efficiency.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of grooving method of external screw thread axial direction groover described in use, comprises the following steps：
1）The fastener for treating external screw thread grooving is connected through a screw thread into mode first to be tightened in the endoporus of installed part, and fastened
The lower surface of part will be abutted in the support block in endoporus；
