Abstract
The utility model provides a novel rapid-replacement type drilling and clamping head. A step with a spring is arranged at the rear end, corresponding to a clamping claw, of a drilling body of the drilling and clamping head, and the spring is mounted on the step and backwards supports an operation sleeve; the middle of the operation sleeve is further connected with a stopping part of a limiting component, and the stopping part is operated and controlled by the operation sleeve and then is in a locking and unlocking state. When in a locking state, the stopping part presses the limiting component towards the inner end of a sliding through hole so that the limiting component can protrude in a motor shaft hole and lock a motor shaft. The novel rapid-replacement type drilling and clamping head is simple in structure, the spring backwards supports the operation sleeve from the rear end of the clamping claw, movement of the clamping claw is guaranteed, the operation sleeve is supported more stably, and therefore the performance of the rapid-replacement type drilling and clamping head is more stable and reliable.
Description
Technical field
The utility model relates to a kind of drill chuck, relates in particular to a kind of for example drill chuck on drilling machine, electric drill of machining equipment and electric tool that is arranged on.
Background technology
In prior art, in drill chuck, be provided with drill body, jaw, thereby by rotation screwing element, driving jaw to travel forward or move backward clamps or the drilling tool that gets loose drill chuck, the rear end face of drill body offers the motor axis hole being connected with motor shaft, and drill chuck utilizes this motor axis hole to be connected with lathe or pistol electric drill.The current drill chuck with quick change syndeton, structure is often very complicated, is not easy to manufacture, and performance is also not easy to stablize.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of novel Quick action type chuck of drilling bit of simple in structure, dependable performance.For this reason, the utility model is by the following technical solutions:
Novel Quick action type chuck of drilling bit, comprises drill body, from the rear end of drill body, to extending in drill body, is provided with axial motor axis hole; Described motor shaft hole wall is provided with the movable through hole of limiting component, in the movable through hole of limiting component, is provided with the mobilizable limiting component for motor shaft; The rear portion of described drill chuck is also provided with control cover, the spring of support and control cover, the backward travel locating part of control cover that can slide vertically, it is characterized in that, the drill body of described drill chuck has the step that carries spring in the rear end of corresponding jaw, described spring carries on described step and to operating sleeve described in rear support; The centre of described operating sleeve is also connected with the block piece of limiting component, described block piece is controlled by described operating sleeve and in locking state and released state, when in locking state, by described block piece, to the inner extruding of slip through hole, limiting component is given prominence in motor axis hole described limiting component motor shaft is pinned.
Adopting on the basis of technique scheme, the utility model also can adopt following further technical scheme:
Described spring is tower spring.
Owing to adopting the technical solution of the utility model, the utility model structure is very simple, and spring from the rear end of jaw support operation cover backward, can ensure jaw motion, simultaneously more stable to the supporting of operating sleeve, make the performance of Quick-change drill chuck more stable, reliable.
Accompanying drawing explanation
Fig. 1 is the partial sectional view of embodiment provided by the utility model.
The specific embodiment
With reference to accompanying drawing.Novel Quick action type chuck of drilling bit provided by the utility model, comprises drill body 1, from the rear end of drill body, to extending in drill body, is provided with axial motor axis hole 11; Described motor shaft hole wall is provided with the movable through hole 14 of limiting component, in the movable through hole 14 of limiting component, is provided with the mobilizable limiting component 7 for motor shaft; The rear portion of described drill chuck is also provided with control cover 3, the spring 6 of support and control cover, the backward travel locating part 24 of control cover that can slide vertically, described drill chuck has the step 12 that carries spring in the rear end of corresponding jaw 4, described spring 6 carries on described step 12 and to operating sleeve described in rear support; The centre of described operating sleeve 3 is also connected with the block piece 30 of limiting component, described block piece 30 is controlled by described operating sleeve and in locking state and released state, when in locking state, by described block piece 30, to the inner extruding of slip through hole 14, limiting component 7 is given prominence to described limiting component 7 pins motor shaft 9 in motor axis hole 11, drawing reference numeral 91 is the arc groove coordinating with limiting component 7 on motor shaft, makes limiting component 7 can pin motor shaft 9.
Described spring 6 can be selected tower spring.
Described backward travel locating part 24 can be a collar being connected with drill body 1 rear end, and block piece 30 can be screwed on the centre bore of controlling cover rear end, and matches with stroke limit part 24, and the backward travel of cover is controlled in restriction.Described limiting component can adopt the rolling elements such as steel ball, also can adopt the slide masses such as pin, post.
