Description
Technical field
The utility model relates to electric tool technical field, refers in particular to the PTO drive disk of electric tool output shaft.
Background technology
Rotating electric tool, except using as electric drill, also can be used as electric screw driver, as long as there is suitable chuck can for clamping drill bit or screwdriver, optional by electronic or manual different purposes.Existing electric tool is rotated via directly driving fixture after reducing gear by motor, if electric tool is used as electric screw driver, the cutter of motor and clamp end is direct-drive, cutter end is directly used for rotation screw time, output shaft for jockey causes the active force of reversion, motor along with rotation, therefore cannot directly can be used as hand-operated tools.Therefore, at the output shaft installing locking mechanism of reducing gear, make the motor of electric tool can forward outputting power, to drive output shaft rotation by this locking mechanism; When this output shaft counter-rotating exerts a force, namely this locking mechanism locks this output shaft makes this output shaft rotate, and the locking of this output shaft can be used as hand-operated tools like this.
The patent No. be 200520009023.5 Chinese patent disclose the locking device of electric tool output shaft, comprise: main shaft, scotch, PTO drive disk, stopper ring, multiple lock pin, main shaft interts in scotch and PTO drive disk, main shaft is connected can realizes Power output with the fin in PTO drive disk, and main shaft is connected by scotch can realizes lock function with lock pin.As shown in Figure 1, existing PTO drive disk has generally comprised circular output panel main body 10, output panel main body 10 upper surface is convexly equipped with multiple along the circumferential direction equally distributed drive block 11, on PTO drive disk, there is obvious step drive block 11 lateral surface and output panel main body 10 junction, because fill out the uneven meeting of powder in the different phenomenon of generation top and the bottom, faying face place bit density during PTO drive disk powder compacting, cause the bond strength of drive block and card poor, stress is concentrated, torsion fracture resistant intensity and shear strength poor, easily rupture.
Utility model content
The purpose of this utility model is exactly the deficiency that exists for prior art and provides a kind of PTO drive disk improving drive block and output panel body bond strength, improve the electric tool output shaft of torsion fracture resistant intensity and shear strength.
To achieve these goals, the technical solution adopted in the utility model is: the PTO drive disk of electric tool output shaft, it includes circular output panel main body, output panel main body upper surface is convexly equipped with multiple along the circumferential direction equally distributed drive block, the maximum gauge enclosing the circle of formation between multiple drive block is mutually less than the external diameter of output panel main body, position output panel main body is positioned at outside each drive block offers avoiding hollow groove along the outer surface profile of respective drive block respectively, the lateral surface that avoiding hollow groove extends radially outward out output panel main body forms the nick shaped structure running through the upper and lower both ends of the surface of output panel main body.
The inner surface of each drive block is respectively equipped with drive surface.
Described drive surface is the V-type angle faces structure protruding be to the inside made up of two vertical plane at an angle to each other.
Described drive block has 3.
Medial surface and the lateral surface of described drive block are arcwall face.
Be entity structure in the middle part of described output panel main body.
The utility model beneficial effect is: the PTO drive disk of the electric tool output shaft that the utility model provides, it includes circular output panel main body, output panel main body upper surface is convexly equipped with multiple along the circumferential direction equally distributed drive block, the maximum gauge enclosing the circle of formation between multiple drive block is mutually less than the external diameter of output panel main body, position output panel main body is positioned at outside each drive block offers avoiding hollow groove along the outer surface profile of respective drive block respectively, the lateral surface that avoiding hollow groove extends radially outward out output panel main body forms the nick shaped structure running through the upper and lower both ends of the surface of output panel main body, drive block lateral surface is made to form straight-through face, avoid like this forming step with the junction of output panel main body outside drive block, can not exist and fill out the uneven problem of powder, each position even density after PTO drive disk powder compacting, eliminate stress concentrated problem, the bond strength of drive block and output panel main body is higher, improve torsion fracture resistant intensity and shear strength, be not easy fracture.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing PTO drive disk.
Fig. 2 is the structural representation of the utility model PTO drive disk.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, as shown in Figure 2, the utility model includes circular output panel main body 20, output panel main body 20 upper surface is convexly equipped with multiple along the circumferential direction equally distributed drive block 21, the maximum gauge enclosing the circle of formation between multiple drive block 21 is mutually less than the external diameter of output panel main body 20, position output panel main body 20 is positioned at outside each drive block 21 offers avoiding hollow groove 22 along the outer surface profile of respective drive block 21 respectively, the lateral surface that avoiding hollow groove 22 extends radially outward out output panel main body 20 forms the nick shaped structure running through output panel main body about 20 both ends of the surface, drive block 21 lateral surface is made to form straight-through face, avoid like this forming step with the junction of output panel main body 20 outside drive block 21, can not exist and fill out the uneven problem of powder, each position even density after PTO drive disk powder compacting, eliminate stress concentrated problem, the bond strength of drive block 21 and output panel main body 20 is higher, improve torsion fracture resistant intensity and shear strength, be not easy fracture.
The inner surface of each drive block 21 is respectively equipped with drive surface 23, for being connected drive shaft with main shaft.Drive surface 23 is the V-type angle faces structure protruding be to the inside made up of two vertical plane at an angle to each other, has better motive force to main shaft.Drive block 21 has 3, can certainly the quantity such as 2,4,5,8.
Medial surface and the lateral surface of drive block 21 are arcwall face, can reduce stress, improve structural strength, and can coordinate with main shaft, stopper ring better.It is entity structure in the middle part of output panel main body 20.
Certainly, the above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
