Abstract
The utility model relates to a spanner drill chuck, including boring body, overcoat, ring gear, clamping jaw, wrenching wheel, it bores the body rear end and still is equipped with a locking cap, the two screw-thread fit, and locking cap and overcoat contact lean on friction and the power locking overcoat that rises. The utility model has the advantages of locking function, it is swift to use, and is convenient, can not make the drilling tool not hard up because of vibration or impact, has rational in infrastructure, convenient assembling, stable performance, reliable operation, safe in utilization, is applicable to the clamping of various drilling tools.
Description
The utility model relates to a kind of drilling tool clamping device, specifically a kind of spanner drill chuck.
We know, existing spanner drill chuck is generally by drill body, overcoat, gear ring, jaw, pulling wheel forms, the overcoat interference is connected on the gear ring, three jaws are installed in respectively in the inclined hole of three five equilibriums on the drill body, gear ring is installed in the gear ring groove of drill body, its underpart be provided with can with pull the tooth that cooperates of wheel, threaded engagement on gear ring and the jaw forms thread transmission, pull wheel by rotating jacket or use and drive the gear ring rotation, gear ring drives in the inclined hole of jaw on drill body through screw thread and moves forward and backward, thereby three-jaw is opened or closure, to reach the purpose of unclamping or clamping drilling tool, the deficiency of said structure is, drill chuck is when work, because vibration or impact, drill chuck is easily loosening, have a strong impact on operating efficiency, poor stability.
The purpose of this utility model is exactly to provide a kind of rational in infrastructure in order to overcome above-mentioned the deficiencies in the prior art, has locking function, high efficiency, safe in utilization, spanner drill chuck efficiently.
For achieving the above object, a kind of spanner drill chuck of the utility model includes drill body, overcoat, gear ring, jaw, pulls wheel, it is characterized in that the drill body rear end also is provided with a locking cap, the two threaded engagement, and locking cap contacts with overcoat.
The utility model is owing to adopt said structure, the rotation lock cap, and it can closely contact with overcoat, by rubbing and the tension locking jacket, has overcome the deficiency that present spanner drill chuck does not have locking device.It manipulates fast, reliable, convenient, have advantages such as rational in infrastructure, easy to assembly, stable performance, reliable operation, be applicable to the clamping of various drilling tools.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a kind of detent mechanism schematic diagram of the present utility model.
As shown in Figure 1, a kind of spanner drill chuck of the utility model, it is provided with drill body 1, overcoat 2, gear ring 3, jaw 4, pull wheel 5, wherein overcoat 2 interference are connected on the gear ring 3, three jaws are installed in respectively in the inclined hole of three five equilibriums on the drill body 1, gear ring 3 is installed in the gear ring groove of drill body, its underpart be provided with can with pull the wheel 5 teeth that cooperate, pull wheel 5 and realize operation by the wheel hole of pulling on the drill body 1, threaded engagement on gear ring 3 and the jaw 4 forms thread transmission, pull wheel 5 by rotating jacket 2 or use and drive gear rings 3 rotations, gear ring 3 drives in the inclined hole of jaw 4 on drill body 1 through screw thread and moves forward and backward, thereby three jaws is opened or closure.The pass of said structure and each parts is a prior art, and this does not describe in detail.
Characteristics of the present utility model are also to be provided with a locking cap 10 in drill body 1 rear end, the two threaded engagement, and locking cap 10 can contact with overcoat 2 upper edges or interior edge.Locking cap 10 available metal materials are made, and also can make of nonmetallic materials.Locking cap 10 is provided with detent mechanism, and it is made up of jackscrew 7, spring 8, steel ball 9, and correspondingly drill body 1 is provided with groove.For preventing that locking cap 10 from coming off, also be provided with back-up ring 6 on the drill body 1 at an upper portion thereof, can be jump ring such as it.
As shown in Figure 2, detent mechanism also can be made up of jackscrew 7, spring 8, locating detent 9 on the utility model locking cap 10, and correspondingly drill body 1 is provided with the groove that cooperates with locating detent 9.
When the utility model uses, pull wheel 5, fix drilling tool by operation.Rotation lock cap 10, it can closely contact with overcoat 2, by friction and tension locking jacket, has overcome the various deficiencies that present spanner drill chuck does not have locking device.
The utlity model has locking function, use fast, convenient, can or not impact because of vibration making brill Tool is loosening, and it is excellent to have rational in infrastructure, easy to assembly, stable performance, reliable operation, use safety etc. Point is applicable to the clamping of various drilling tools.
