Abstract

A kind of classification positioning buffer protection mechanism, mechanism installation is protected by classification positioning buffer protection in the lead screw tail portion of screw mechanism, it includes sleeve that classification positioning buffer protection, which protects mechanism, ring flange and multiple butterfly springs, sleeve is set in the tail portion of screw rod, the outer end face of sleeve offers the annular groove being connected to barrel bore, spacer is successively set in annular groove from bottom to top, locking nut and multiple butterfly springs, locking nut is fixed to each other with the lead screw, it is shored by locking nut the bottom of butterfly spring, butterfly spring is resisted against fixed lid loaded on the ring flange of sleeve;The lead screw tail portion is provided with the inductive switch with lead screw cooperation.The utility model protects mechanism by the way that classification positioning buffer protection is arranged in the tail portion of lead screw; classification positioning buffer protection, which protects mechanism, has suitable pressing force by the compression of lead screw; to reduce the abrasion of the contact surface to classification positioning tooth bar; maintenance cost is reduced, service life is improved and is classified the precision of positioning mechanism.

Description

A kind of classification positioning buffer protection mechanism
Technical field
The utility model belongs to machine tool component device field, especially related with a kind of classification positioning buffer protection mechanism.
Background technique
Classification positioning mechanism is suitable for most lathes for having large-scale pillar construction and having longer stroke on column.Classification Positioning mechanism is arranged usually on column classification positioning tooth bar, classification positioning tooth bar be bonded with column and with relatively move Component carries out stablizing high-precision position control.Inductive switch is arranged in every grade of positioning in existing classification location structure, is feeling It answers the laggard line delay in position to fall, make the block being arranged on the nut of screw mechanism and is classified the work face contact of positioning tooth bar, This structure manually rule of thumb adjusts the extruding degree needs of contact surface during component is delayed and falls, and contacts Surface pressure floats larger, situations such as be easy to causeing the excessive deformation of tooth surface of pressure or pressure too small influence precision.
Utility model content
The flank of tooth is caused to become for pressure is excessive present in working face contact process of the existing block with classification positioning tooth bar The problems such as shape or pressure too small influence precision, the utility model are intended to provide a kind of classification positioning buffer protection mechanism.
For this purpose, the utility model uses following technical scheme: a kind of classification positioning buffer protection mechanism, characterized in that silk The lead screw tail portion of thick stick mechanism positions buffer protection by the classification and protects mechanism installation, classification positioning buffer protection Bao Jigoubao Sleeve, ring flange and multiple butterfly springs are included, the sleeve is set in the tail portion of screw rod, and the outer end face of sleeve is offered and covered The annular groove of tube inner chamber connection, annular groove are successively set with spacer, locking nut and multiple butterfly springs, lock from bottom to top Tight nut is fixed to each other with the lead screw, and the bottom of butterfly spring is shored by the locking nut, butterfly spring against In on the ring flange of the opening of fixed annular groove of the lid loaded on sleeve outer end;The lead screw tail portion is provided with matches with lead screw The inductive switch of conjunction.In use, be provided with the flexible block of hydraulic-driven on nut seat, when nut seat is brought by lead screw to dividing At the specified positioning grade space of grade positioning tooth bar, block is stretched out by hydraulic-driven, and lead screw continues to rotate at this time, due to lead screw Tail portion has certain axial float relative to sleeve by housing supports, lead screw, and lead screw will continue to upward play and squeeze at this time Pressure butterfly spring, and contact face contact of the block with positioning tooth bar, when lead screw cooperates with the inductive switch, inductive switch Signal is provided, lead screw stops operating, and due to the effect of elastic force, elastic force can be applied on nut seat disc spring, to reduce nut seat Abrasion to the contact of positioning tooth bar reduces maintenance cost, improves service life and is classified the precision of positioning mechanism.
The utility model can achieve following the utility model has the advantages that 1, the utility model, which passes through, is arranged classification calmly in the tail portion of lead screw Mechanism is protected in bit buffering protection, and classification positioning buffer protection, which protects mechanism, has suitable pressing force by the compression of lead screw, thus The abrasion for reducing the contact surface to classification positioning tooth bar, reduces maintenance cost, improves service life and is classified positioning mechanism Precision.2, length of the utility model by the spacer of replacement lead screw, the quantity of adjustable butterfly spring, to make butterfly bullet Spring reaches best dynamics to the elastic force that nut seat discharges, and guarantees to reduce nut seat to the abrasion dynamics of positioning tooth bar.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is partial enlargement diagram at a in Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.
As Figure 1-Figure 2, the lead screw tail portion of screw mechanism positions buffer protection by the classification and protects mechanism installation, It includes sleeve 3, ring flange 6 and multiple butterfly springs 7 that classification positioning buffer protection, which protects mechanism, and sleeve is set in the tail portion of screw rod 1, The outer end face of sleeve offers the annular groove being connected to barrel bore, and annular groove is successively set with spacer 8, locking nut from bottom to top 9 and multiple butterfly springs, locking nut be fixed to each other with the lead screw, the bottom of butterfly spring passes through the lock Tight nut is shored, and butterfly spring is resisted against on the ring flange of the opening of fixed annular groove of the lid loaded on sleeve outer end;It is described Lead screw tail portion be provided with lead screw cooperation inductive switch 10.In use, it is flexible to be provided with hydraulic-driven on nut seat 2 Block 5, when nut seat is brought by lead screw to the specified positioning grade space of classification positioning tooth bar 4, block is stretched by hydraulic-driven Out, lead screw continues to rotate at this time, and since the tail portion of lead screw is by housing supports, lead screw relative to sleeve there is certain axial direction to alter Dynamic, lead screw will continue to upward play and squeeze butterfly spring at this time, and contact face contact of the block with positioning tooth bar, when lead screw with When the inductive switch cooperates, inductive switch provides signal, and lead screw stops operating, effect of the disc spring due to elastic force, elastic force meeting It is applied on nut seat, to reduce the abrasion of contact of the nut seat to positioning tooth bar, reduces maintenance cost, improve using the longevity The precision of life and classification positioning mechanism.
