The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Structure of the present invention sees that Fig. 1 is to shown in Figure 10.Figure grade explanation: drill gun main body 1, self-tightening screw 2, centralized positioning plate 3, reference column 31, drill chuck 4, ring washer 41, cross recess 42, runing rest 5, centre bore 51, suppending hole 52, center positioning hole 53, plane bearing 6, pad 7, central shaft 8, flexible locating support 9, the inclined-plane 91 of turning back, groove 92, connecting hole 93, connecting hole 94, connecting hole 95, connecting hole 96, wind spring 10, annulus button 101, crotch 102, flexible locating support seat 11, connecting hole 111, connecting hole 112, rectangular through hole 113, T type groove 114, rectangular through hole 115, rocking bar 12A, through hole 12A1, flange 12A2, rectangular breach 12A3, rocking bar core 12B, rectangular breach 12B1, flange 12B2, through hole 12B3, T type groove 12B4, spring 12C, shouldered shaft 13, retaining lock 14.
The flexible location locking mechanism of rocker-type is fitted in the flexible locating support 9 and the space that relatively moves between the flexible locating support seat 11 of drilling tool conversion equipment, this rocking bar 12A is tabular, one end is the parallel plane of turning back, be shaped on through hole 12A1 on the plane, be fixed on behind shouldered shaft 13 external diameters and the through hole 12A1 kink in the connecting hole 96 of flexible locating support 9; Rocking bar core 12B one end is the parallel plane of turning back, and is shaped on through hole 12B3 on the plane, is fixed on behind shouldered shaft 13 external diameters and the through hole 12B3 kink in the connecting hole 111 of flexible locating support seat 11; Rocking bar core 12B is shaped on T type groove 12B4, rocking bar 12A is inlaid in the T type groove 12B4, the two can be in T type groove telescopic moving relatively, because rocking bar 12A, the relative end of rocking bar core 12B all is shaped on rectangular breach 12A3 and 12B1, be placed with shared spring 12C in the rectangular breach, the both ends of the spring endoporus is inlaid on flange 12A2 and the flange 12B2, after spring 12C settles in this total rectangular breach, spring 12C is under external force is compressed power effect with expansionary force, the relative telescopic moving of rocking bar 12A with rocking bar core 12B, it is because promotion or the pulling of hand to stretching locating support that above-mentioned said spring 12C is compressed with expanding, force spring to be compressed after driving rocking bar and rocking bar core, when expansion, help flexible locating support to push terminal point to again.
One end of flexible locating support 9 is a groove 92, and this groove 92 is installing spaces of the flexible location locking mechanism of rocker-type; Its path one end is fixed in the connecting hole 96 of flexible locating support 9 behind the through hole 12A1 of shouldered shaft 13 external diameters connection rocking bar 12A; Its path one end is fixed in the connecting hole 111 of flexible locating support seat 11 behind the through hole 12B3 of shouldered shaft 13 external diameters connection rocking bar core 12B, after above-mentioned said member connection and the combination, when pulling moving or promote drill chuck together with flexible locating support 9, flexible locating support 9 relatively moves with flexible locating support seat 11, so the shouldered shaft 13 that is fixed on the connecting hole 111 on shouldered shaft 13 and the flexible locating support seat on the connecting hole 96 of flexible locating support moves as rightabout respectively, connected thereupon rocking bar 12A and rocking bar core 12B also do the rightabout swing, because they wave the change that the variation of angle brings the radial distance size thereupon, force rocking bar flexible in rocking bar core, force compression or the expansion of spring 12C simultaneously, when expansion, flexible locating support is pushed to terminal point, backing pin 14 moves rectangular through hole 113 1 ends that end flexible locating support seat and is blocked locking, for guaranteeing that the locking dynamics increases on the rocking bar core limit wind spring 10 is installed, wind spring 10 1 ends are shaped on annulus button 101, in the connecting hole 93 that is fixed on flexible locating support 9 behind shouldered shaft external diameter and annulus button 101 kinks, the other end is shaped on crotch 102 and is inlaid in the connecting hole 112 of flexible locating support seat 11, flexible like this locating support 9 is pulled out or is advanced in flexible locating support seat 11 when ending terminal point, the tension force of wind spring 10 can help to strengthen locking force, the dynamics of the two is enough to the issuable alien influence of balance, especially only advance and to have reciprocal external force effect behind the terminal point, this moment, the tension force of two springs forced the backing pin 14 that is fixed on the flexible locating support to be returned to rectangular through hole 113 left side terminal locations rapidly, because above technical measures, make the rear end face of drill chuck and the end face of suppending hole 52 remain bigger clearance distance, more do not have any contact or friction; At flexible locating support 9 other ends are the inclined-planes 91 of turning back, by the centre bore 51 of central shaft 8 with runing rest, and 6 two of plane bearings, pad 7 connects on the connecting hole 95 on the inclined-plane 91 of turning back that is placed in flexible locating support; The two port of runing rest 5 claims to be shaped on the plane respectively one of center positioning hole 53, be enclosed within the drill gun main shaft after drill chuck 4 is pressed locking and lock regularly when holding, along with flexible locating support advances inwards, center positioning hole 53 is also followed the reference column 31 that is inserted in band awl on the centralized positioning plate 3, because above-mentioned said technical measures, suppending hole 52 internal diameters of runing rest at this moment and the drillstock external diameter of drill chuck keep bigger gap uniformly; The work that can be driven to rotate after along with the propelling of flexible locating support and drill gun main shaft flange setting-in of the cross recess 42 of drill chuck 4; When needs transposing another drilling tool, at first hand push cover after the locking of the drill chuck 4 on the drill gun main shaft together with flexible locating support 9 outwards pulling with the tension force acting in conjunction of spring 12C under, backing pin 14 on the flexible locating support is blocked by the other end of the rectangular through hole 113 of flexible locating support seat 11, at this moment change another drill chuck 4 again before the drill gun main shaft, said operating process gets final product above repeating.At the suppending hole 52 that can be provided with on the drilling tool conversion equipment more than two, so that hang the transposing use that a plurality of drill chucks are realized a plurality of drilling tools.
The invention has the advantages that: rocking bar and rocking bar core adopt the work of T type groove to be connected, and its socket is convenient, and the space of being occupied is little; Hand impels the spring compressing and expanding to the promotion or the pulling of flexible locating support, and the tension force of expansion helps the locking force of flexible locating support in terminal again; The tension force of wind spring is the another measure that increases locking force, needs only the transfer process that a hand just can be finished whole drilling tool easily now, and is simple to operation, rational in infrastructure.
Though the present invention illustrates and describes by embodiment,, those skilled in the art should understand, and in the claim scope, can do the various variations on form and the details.
