Abstract
The utility model discloses a chuck assembly on an electric or pneumatic tool. The chuck assembly comprises a rotating shaft and a clamping shaft. An installation hole is formed in the rotating shaft. The two axial ends of the clamping shaft are a threaded end and a conical clamping portion respectively. The clamping shaft comprises a clamping hole for installing the tool. The clamping hole penetrates through the threaded end and the clamping portion respectively. A plurality of cutting grooves communicated with the clamping hole are formed in the wall face of the clamping portion in the axial direction. The threaded end and the clamping portion are inserted into the installation hole, and the threaded end and the installation hole are in threaded connection to enable the clamping portion to axially move. When moving, the clamping portion makes contact with the installation hole, and therefore the clamping portion clamps the tool in a matched mode. The chuck assembly on the electric or pneumatic tool is simple in structure, so that the cost is saved, and use is more convenient.
Description
Technical field
The utility model belongs to the frock field on electronic or pneumatic tool, is specifically related to the chuck component on a kind of electronic or pneumatic tool.
Background technology
As shown in Figure 1, existing chuck component generally includes rotating shaft 1, nut 11 and folder axle 2, described folder axle 2 is plugged in the installing hole of rotating shaft 1, then nut 11 cover odd even volumes are being pressed from both sides in axle 2 and rotating shaft 1, nut 11 is threaded with rotating shaft 1, thereby make to press from both sides axle 2 to installing hole medial movement, because press from both sides axle 2 with the handle part that cuts groove and cone shape, thereby its outer wall can move to the center of handle part compression cutter when the outer wall of handle part contacts with installing hole.But such modular construction is complicated, so return, cause cost to increase, and handling cutter bother very much.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to propose a kind of chuck component simple in structure, high to solve in conventional art cost, the problem of handling cutter trouble.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the chuck component on a kind of electronic or pneumatic tool, comprises rotating shaft and folder axle; Described rotating shaft is provided with an installing hole; The axial two ends of described folder axle are respectively the end of thread and cone shape clamping part; Described folder axle includes the folder hole of a mounting cutter, and described folder hole runs through respectively the end of thread and clamping part; On the wall of described clamping part, be provided with vertically the groove that cuts that several are communicated with folder hole; The described end of thread and clamping part are all plugged in installing hole and the end of thread is threaded clamping part is moved axially with installing hole, thereby described clamping part makes clamping part cooperation clamp-on tool by contacting with installing hole when mobile.
The end face of described clamping part is provided with axial locking end; The two ends, left and right of described locking end wall are provided with otch.
Described folder hole upwards runs through locking end.
The described groove that cuts upwards runs through locking end.
The described groove that cuts be take the axial line of folder hole and is distributed on the wall of clamping part and locking end as axle center annular.
(3) beneficial effect
Chuck component on electronic or pneumatic tool of the present utility model, by the end of thread being set on folder axle, the end of thread is directly threaded with the installing hole of rotating shaft, thereby can make handle part move axially, therefore can, by the aperture of the touch controls folder hole with installing hole, make handle part directly be fixed cutter, and without realizing by nut, therefore simple in structure, therefore not only provide cost savings, and handling cutter is very convenient.
Accompanying drawing explanation
Fig. 1 be prior art electronic or pneumatic tool on the structural representation of chuck component;
Fig. 2 is the structural representation of the chuck component on electronic or pneumatic tool of the present utility model;
Fig. 3 is the stereogram of folder axle;
In figure, 1 for installing hole, 10 for cutter, 11 is nut for otch, 9 for cutting groove, 7 for locking end, 8 for folder hole, 6 for clamping part, 5 for the end of thread, 4 for folder axle, 3 for rotating shaft, 2.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Chuck component on a kind of electronic or pneumatic tool as shown in Figures 2 and 3, comprises rotating shaft 1 and folder axle 2; The axial two ends of described folder axle 2 are respectively the end of thread 3 and cone shape clamping part 4; Described folder axle includes the folder hole 5 of a mounting cutter 10, and described folder hole 5 runs through respectively the end of thread 3 and clamping part 4; The all once machine-shaping on lathe of the described end of thread 3, folder hole 5 and clamping part 4, so guaranteed the precision of its axiality.On the wall of described clamping part 4, be provided with vertically 4 be communicated with folder hole 5 cut groove 6, and described in cut groove and take the axial line of folder hole 5 and be distributed on the wall of clamping part 4 as axle center annular.By cutting groove 6, can make clamping part 4 move along its axle center, described rotating shaft 1 is provided with an installing hole 9; The described end of thread 3 and clamping part 4 are all plugged in installing hole 9 and the end of thread 3 is threaded clamping part 4 is moved axially with installing hole 9, described clamping part 4 when mobile by contacting with installing hole 9, thereby control folder hole 5 aperture, therefore make clamping part 4 coordinate clamp-on tools 10.Therefore without nut, can realize operation.
For conveniently assemble and disassemble, the design personnel are provided with an axial locking end 7 at the end face of described clamping part 4; The two ends, left and right of described locking end wall are provided with otch 8, and described folder hole 5 upwards runs through locking end 7, described in cut groove 6 and upwards run through locking end 7, this structural reinforcing the length of folder hole 5, thereby increased the contact area of cutter 10 with folder hole, clamp more firm.And facilitate vice control locking end 7 to make the end of thread 3 rotations drive clamping part 4 to move axially by breach 8.
Chuck component on electronic or pneumatic tool of the present utility model is when assembling cutter 10, first cutter is plugged in folder hole 5, then the end of thread 3 and clamping part 4 are plugged in the installing hole 9 of rotating shaft 1, then by vice, control the end of thread 3 rotations moves clamping part 4 at the bottom of the hole of installing hole 9, after the lateral wall of clamping part 4 contacts with installing hole 9, thereby described clamping part 4 is by conical structure and cut groove 6 and move folder hole 5 apertures are diminished to folder hole 5, therefore can clamp-on tool 10, thereby without nut is set, make chuck component overall structure simple, therefore reduced cost, assemble convenient again.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
