Abstract
The utility model discloses a latching spanner drill chuck, which consists of a chuck body, a shell, a nut connected with a jaw, and which is further provided with a component for pulling the nut. The utility model is to pull the nut tightly by operating the component after the novel drill clamped, thereby, the nut doesn't reverse rotation when the drill chuck runs and eliminates the possibility that the chuck clamped by jaws come adrift when acted on impulse loading. The component for pulling the nut of the utility model maybe the one the nut tightly from the front or the back of the nut matched with a spring when the drill chuck is running, or pulling the nut tightly from the front or the back through the rotation of thread, such as a bolt, a nut, or some component matched with them.
Description
Technical field
The utility model relates to a kind of spanner drill chuck, relates in particular to a kind of for example spanner drill chuck on the drilling machine of machining equipment that is installed in.
Background technology
The jaw that spanner drill chuck generally comprises drill body, nut, is connected with nut thread by handling spanner, directly drives nut, or drives shell or other connectors, and and then drive the nut rotation, make the jaw advance and retreat, thereby clamp or the drilling tool that gets loose.Although this drill chuck clamping force is bigger, when being hit under the load effect, the drill bit of jaw clamping still might become flexible and skid even come off the continuity of influence processing.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of self-locking spanner drill chuck that overcomes above-mentioned defective.For this reason, the utility model by the following technical solutions: it comprises drill body, shell, nut, the jaw that is connected with nut thread, and it also is provided with the element that holds out against nut.The said element that holds out against nut of the utility model, can be when drill chuck is worked, the element that the place ahead or the rear from nut that cooperates with spring holds out against nut, it also can be rotation by screw thread, the element that holds out against nut from the place ahead or the rear of nut, such as screw, bolt, or the element that cooperates with screws bolts.
Owing to adopt above technical scheme, after drilling tool is clamped, hold out against the element of nut by operation, make it hold out against nut, like this, nut can not produce backward rotation when drill chuck is worked, and the drill bit that the load that can prevent to be hit is done time spent jaw clamping produces loosening possibility of skidding.
Description of drawings
Fig. 1 partly cuts open figure for a kind of embodiment's of the utility model.
The specific embodiment
With reference to accompanying drawing.The utility model comprises drill body 1, shell 2, nut 3, the jaw 4 that is connected with nut thread, and it is provided with the element that holds out against nut.
The described element of nut that holds out against is for screwing in and act on the screw 5 of nut front end face from the drill body front end.
Drawing reference numeral 11 is the set screwed hole that cooperates with screw 5 of drill body front end, and drawing reference numeral 51 is the interior hexagonal on the head of screw.
In the present embodiment, shell and nut interference fit.During drill chuck work, rotation case drives nut, after making jaw clamp drilling tool, turn screw 5, nut is held out against in nut groove 12 by screw 5, like this, the load effect even be hit, because held out against by screw, nut can not produce reverse rotation yet, the drill bit of jaw clamping can not become flexible and skid, thereby has guaranteed the continuity of processing.In the time will shirking drilling tool, earlier oppositely turn screw, it is removed the holding out against of nut, reverse rotation shell then, thus drive the nut reverse rotation, make the jaw drilling tool that gets loose.
Screw or bolt as the rotation by screw thread, hold out against or loosen the element of nut, are to hold out against a kind of preferred in the element of nut, and it makes that the structure of locking type spanner drill chuck is simpler, and the processing of being more convenient for is also convenient during operation.Especially, screw or bolt are arranged on the structure of the front end of drill body, not only can utilize spanner drill chuck front end cylindrical that the screwed hole of cooperation is set easily, make the structure of drill chuck more reasonable, simultaneously, from the angle of using, be more convenient for to the operation of screw or bolt.
Claims (2)
1, a kind of self-locking spanner drill chuck comprises drill body, shell, nut, the jaw that is connected with nut thread, it is characterized in that it is provided with the element that holds out against nut from the place ahead or the rear of nut.
2, a kind of self-locking spanner drill chuck as claimed in claim 1 is characterized in that described adjustable element of nut that holds out against is for screwing in and act on the screw of nut front end face from the drill body front end.
