Description
Technical field
The present invention relates to provision for disengagement technical field, more particularly to a kind of provision for disengagement of threaded insert.
Background technology
The need for bonding strength etc., application of the metal insert in plastic products is more and more wider.And in working of plastics
In production in enormous quantities, because the product quality caused by a variety of causes is unqualified, much discarded parts are produced.Material to discarding part
Carry out recycling to be highly desirable to, it is therefore desirable to which the metal insert in discarded part is taken out into classification, realize to different materials
Recycle, be conducive to environmental protection and cost-effective.Therefore, rapidly realize that metal insert separates that have very much must with working of plastics
Will.
Existing metal insert is pulled down in the reality plastic products using the method for tapping general at present, but due in engineering plastics
Mostly added with glass fibre, intensity is higher, and this kind of method is not only laborious and less efficient.Therefore, a kind of screw thread how is provided embedding
The provision for disengagement of part, is succinctly dismantled with the high efficiency for realizing the threaded insert for meeting Multiple Type, is current art technology neck
Domain technical problem urgently to be resolved hurrily.
The content of the invention
The invention aims to overcome the shortcomings of above-mentioned background technology, there is provided a kind of threaded insert of simple structure is torn open
Handler, it is adaptable to the high efficiency dismounting of metal threaded inserts in plastic products.Technical scheme is as follows：
A kind of threaded metal inserts provision for disengagement, for dismantling threaded metal inserts 11, including by motor-driven transmission
Axle 1, fixed hub 2, detachable axle sleeve 3, special bolt 4 and turning handle 10, it is characterised in that
Contain the screwed hole 6 for connecting special bolt 4 in one end of power transmission shaft 1；
Turning handle 10 is connected by ratchet structure 7 with power transmission shaft so that turning handle 7 can drive power transmission shaft 1 to rotate and power transmission shaft 1
Turning handle 7 can not be driven to rotate；
Fixed hub 2 is axially fixed on power transmission shaft 1 by thrust bearing 5, and power transmission shaft 1 and fixed hub 2 can be mutual
Rotate；
The two ends of special bolt 4 contain installation screw thread 13 and match screw thread 14, by installing screw thread 13 with the phase of power transmission shaft 1
Even, the matching diameter of screw thread 14 matches with the diameter of thread of inserts 11；
Detachable axle sleeve 3 is connected to fixed hub 2, and its internal diameter is more than the external diameter of inserts 11, and its axial length is more than inserts 11
Axial length.
Preferably, described threaded metal inserts provision for disengagement, it is characterised in that detachable axle sleeve 3 has
It is magnetic, realizes being connected with the weakness of fixed hub 2 by magnetic force；Contain one end end of matching screw thread 14 of special bolt 4
Cross groove 15.
The present invention is right compared with the prior art, fully shows that it is advantageous in that：Can be realized by different special bolts many
Plant the dismounting of the metal insert of different internal threads and removal efficiency is high.
Brief description of the drawings
Fig. 1 is the structural representation of this threaded insert provision for disengagement.
Fig. 2 is the structural representation and its right view of special bolt.
Specific implementation measure
Fig. 1 and Fig. 2 give this kind of application example of the embedding provision for disengagement of screw thread.Wherein Fig. 1 changes threaded insert provision for disengagement
Structural representation, Fig. 2 for special bolt structure and its right view.
The threaded insert provision for disengagement includes power transmission shaft 1, fixed hub 2, detachable axle sleeve 3, special bolt 4, the He of motor 9
Turning handle 10.Power transmission shaft 1 is needed containing various keyways, boss etc. according to its connection, and the screwed hole 6 of connection is contained in its one end；
Motor 9 is connected by shaft coupling 8 with power transmission shaft 1 so that motor 9 can drive power transmission shaft 1 to realize rotating；Turning handle 10 passes through ratchet
Structure 7 is connected with power transmission shaft so that turning handle 7 can drive that power transmission shaft 1 is rotated and power transmission shaft 1 can not drive turning handle 7 to rotate.It is fixed
Axle sleeve 2 is axially fixed on power transmission shaft by thrust bearing 5, there is certain interval between the two, both is mutually rotated；Can
Dismounting axle sleeve 3 is placed in fixed hub 2, there is certain interval between the two, and easy to disassemble, the internal diameter of detachable axle sleeve 3 is greater than
Inserts external diameter, its axial length is greater than the axial length of inserts, can accommodate inserts so that inserts is extracted completely, no
Just withstood when can pull out half.Detachable axle sleeve 3 has magnetic, realizes being connected with the weakness of fixed hub 2 by magnetic force.
The two ends of special bolt 4 contain installation screw thread 13 and match screw thread 14, are connected with power transmission shaft 1 by installing screw thread 13,
The matching diameter of screw thread 14 matches with the internal thread diameter of inserts 11, and cross groove is contained in matching screw thread 14 one end end
15.Multiple special bolts can be customized according to different metal insert internal thread diameters.
When being dismantled to metal insert 11, corresponding special bolt 4 is fixed on by cross groove 15 with screwdriver
One end of power transmission shaft 1, detachable axle sleeve 3 is placed on fixed hub 2；Handle 10 is slowly rotated, makes special bolt 4 embedding with metal
One end that the internal thread of part 11 matches is initially entered into metal insert 11；Then start motor 9, drive special bolt 4 to rotate, will
Metal insert 11 is forced to extract from working of plastics 12, and now metal insert 11 is placed on special bolt 4 and positioned at removable Lower shaft sleeve 3
It is interior；Finally detachable axle sleeve 3 is unloaded, metal insert 11 is back-outed, complete dismounting.
