The utility model locking type spanner drill chuck advantage is: at work, drill chuck is hit under the effect of load, because the effect of retaining mechanism, the drill bit of clamping also can clamp reliably.
Description of drawings
Fig. 1 is the half sectional view of a kind of embodiment of locking type spanner drill chuck, and the internal structure of locking type spanner drill chuck is shown;
Fig. 2 is the vertical view of locking type spanner drill chuck;
Fig. 3 is the cutaway view along A-A among Fig. 1, and the retaining mechanism of locking type spanner drill chuck is shown.
The specific embodiment
Before describing the utility model in detail, define relational language earlier:
Alleged " front end " of the utility model means in the locking type spanner drill chuck, an end of each jaw clamping drilling bit, the i.e. lower end of Fig. 1;
Alleged " rear end " of the utility model mean in the locking type spanner drill chuck, with the machining tool for example end that is connected of drilling machine, the i.e. upper end of Fig. 1.
Below in conjunction with the embodiment shown in the figure the utility model is described further:
As shown in Figure 1, the locking type spanner drill chuck that the utility model provides comprises drill body 1, shell 2, gear ring 3, jaw 4 and retaining mechanism.Drill body 1 is loaded in the shell 2.Drill body 1 is hollow form, along the inclined hole that circumferentially equidistantly is provided with three inclinations, slidably jaw 4 is housed in each inclined hole in the hollow drill body 1, and the outside of jaw 4 is provided with screw thread.Drill body 1 middle part is provided with gear ring 3, and gear ring 3 is a two halves formula structure, and inboard tapered, the inboard of gear ring 3 is provided with the screw thread that cooperatively interacts with jaw, and gear ring 3 outer round surface and shell 2 are interference fit.Hollow drill body 1 is provided with cannelure with the auxiliary section of gear ring 3, and this cannelure matches with the endoporus of gear ring 3 bottoms.Radially have two square holes on the annular surface that shell 2 upper ends dwindle, be provided with the spring leaf 6 of locking effect together in the hole, the annular surface that shell 2 upper ends dwindle is equipped with a lock sleeve 5 outward, and the inner surface of lock sleeve 5 offers some grooves, and drill body 1 rear end is provided with a circlip for shaft 5.
As shown in Figure 3, the shell 2 tops left side as shown have a big square hole 21, the right has a small square hole 22 relatively, the large U type projection 61 of spring leaf 6 is placed in the big square hole 21, corresponding little U type projection 62 is placed in the small square hole 22, have three grooves on lock sleeve 5 inner peripheral surfaces as shown, the large U type projection 61 of spring leaf 6 withstands in the big V-type groove 51 of lock sleeve 5, little U type projection 62 withstands in the little V-type groove 52, (from the drill chuck front end) rotation lock cover 5 clockwise, the inclined-plane of the V-type trough rim in the lock sleeve 5 just forces spring leaf 6 inwardly to compress, sawtooth 11 clampings on the perk 63 of spring leaf 6 and drill body 1, and the little U type projection 62 of spring leaf 6 slips over groove 53 from little V-type groove 52, shell 2 just is connected together with drill body 1 like this, and shell 2 is interference fit with gear ring 3, thereby has realized locking.As shown in Figure 2, the circlip for shaft 7 of drill body 1 rear end can prevent coming off of lock sleeve 5.
