Description
Technical field
The present invention relates to provision for disengagement technical field, particularly relate to a kind of provision for disengagement of threaded insert.
Background technology
Due to the needs of bonding strength etc., the application of metal insert in plastic products is more and more wider.And in the production in enormous quantities of working of plastics, the product quality caused due to a variety of causes is defective, produce a lot of discarded part.The material of discarded part is recycled and is necessary very much, therefore need the metal insert in discarded part to take out classification, realize the recycling to different materials, be conducive to environmental protection and cost-saving.Therefore, metal insert is realized rapidly necessary with being separated of working of plastics.
Generally adopts at present in the method reality plastic products knocked and show pulling down of metal insert, but owing to being mostly added with glass fibre in engineering plastics, intensity is higher, this kind of method is not only required great effort and efficiency is lower.Therefore, how providing a kind of provision for disengagement of threaded insert, succinctly dismantle with the high efficiency realizing the threaded insert meeting Multiple Type, is current art technology field technical problem urgently to be resolved hurrily.
Summary of the invention
The object of the invention is the deficiency in order to overcome above-mentioned background technology, providing a kind of structure simple threaded insert provision for disengagement, be applicable to the high efficiency dismounting of metal threaded inserts in plastic products.Technical scheme of the present invention is as follows:
The provision for disengagement of a kind of threaded metal inserts, for dismantling threaded metal inserts 11, comprise by motor-driven power transmission shaft 1, fixed hub 2, detachable axle sleeve 3, special bolt 4 and turning handle 10, is characterized in that,
The screwed hole 6 for connecting special bolt 4 is contained in one end of power transmission shaft 1;
Turning handle 10 is connected with power transmission shaft by ratchet structure 7, and turning handle 7 can be driven, and power transmission shaft 1 rotates and power transmission shaft 1 can not drive turning handle 7 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 rotate mutually;
The two ends of special bolt 4 are contained installation screw thread 13 and mate screw thread 14, and be connected with power transmission shaft 1 by installing screw thread 13, the diameter of thread of coupling screw thread 14 diameter and inserts 11 matches;
Detachable axle sleeve 3 is connected to fixed hub 2, and its internal diameter is greater than inserts 11 external diameter, and its axial length is greater than the axial length of inserts 11.
Preferably, described threaded metal inserts provision for disengagement, is characterized in that, detachable axle sleeve 3 has magnetic, realizes being connected with the weakness of fixed hub 2 by magnetic force; Cross groove 15 is contained in the end, coupling screw thread 14 one end of special bolt 4.
The present invention is right compared with the prior art, and fully its superiority of display is: can be realized the dismounting of the metal insert of multiple different internal thread by different special bolts and removal efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of this threaded insert provision for disengagement.
Fig. 2 is structural representation and the right view thereof of special bolt.
Concrete implementing measure
Fig. 1 and Fig. 2 gives the application example of this kind of embedding provision for disengagement of screw thread.Wherein Fig. 1 changes the structural representation of threaded insert provision for disengagement, and Fig. 2 is structure and the right view thereof of special bolt.
This threaded insert provision for disengagement comprises power transmission shaft 1, fixed hub 2, detachable axle sleeve 3, special bolt 4, motor 9 and turning handle 10.Power transmission shaft 1 needs containing various keyway, boss etc. according to its connection, contains the screwed hole 6 connected in its one end; Motor 9 is connected with power transmission shaft 1 by shaft coupling 8, makes motor 9 that power transmission shaft 1 can be driven to realize rotating; Turning handle 10 is connected with power transmission shaft by ratchet structure 7, and turning handle 7 can be driven, and power transmission shaft 1 rotates and power transmission shaft 1 can not drive turning handle 7 to rotate.Fixed hub 2 is axially fixed on power transmission shaft by thrust bearing 5, has certain interval between the two, makes both mutually rotate; Detachable axle sleeve 3 is placed in fixed hub 2, has certain interval between the two, is convenient to dismounting, the internal diameter of detachable axle sleeve 3 is greater than inserts external diameter, and its axial length is greater than the axial length of inserts, can hold inserts, inserts is extracted completely, a half can not be pulled out and just withstood.Detachable axle sleeve 3 has magnetic, realizes being connected with the weakness of fixed hub 2 by magnetic force.
Special bolt 4 two ends are contained installation screw thread 13 and are mated screw thread 14, and be connected with power transmission shaft 1 by installing screw thread 13, coupling screw thread 14 diameter and inserts 11 internal thread diameter match, and cross groove 15 is contained in coupling end, screw thread 14 one end.Multiple special bolt can be customized according to different metal insert internal thread diameter.
When metal insert 11 is dismantled, by cross groove 15, corresponding special bolt 4 is fixed on one end of power transmission shaft 1 with screwdriver, detachable axle sleeve 3 is placed on fixed hub 2; Slowly turning handle 10, one end that special bolt 4 and metal insert 11 internal thread are matched tentatively enters in metal insert 11; Then starter motor 9, drive special bolt 4 to rotate, forced by metal insert 11 to extract from working of plastics 12, now metal insert 11 to be placed on special bolt 4 and to be positioned at removable Lower shaft sleeve 3; Finally detachable axle sleeve 3 is unloaded, metal insert 11 is back-outed, completes dismounting.
