Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
Fig. 1 to Fig. 6 is please referred to, the utility model provides a kind of magnetic tooth machining unit, including pedestal 1, is fixed on pedestal 1
Support arm 2 and the sleeve 3 that 2 free end of support arm is arranged in, the pedestal 1 are magnet base, and magnet base has switch 14, the sleeve
Bearing 4 is equipped in 3, bearing 4 includes outer ring, ball and inner ring, and rotary shaft 5, the rotary shaft 5 are inserted in the axis hole of inner ring
Upper end be arranged handle 6, lower end have mounting hole 7, gripping sleeve 8 is embedded in mounting hole 7, a screw tap 9 is plugged into gripping sleeve 8
Interior, screw tap 9 has upper section 10, middle section 11 and lower section 12, and upper section 10 is square shaft, and middle section 11 is circular shaft, and lower section 12 is cutting cone, institute
State 11 position of middle section that gripping sleeve 8 is in screw tap 9；One locking screw mother set, 13 twist-on is in the lower end of rotary shaft 5, to compress clamping
Set 8, shrinks gripping sleeve 8 radially inward, and clamp screw tap 9.
The gripping sleeve 8 includes ontology 15 and the axis hole 16 that 15 center of ontology is arranged in, and the ontology 15 includes epicone
Body 17 and lower cone 18, on the outer peripheral surface of ontology 15 be between upper cone 17 and lower cone 18 equipped with annular groove 19, is described
The free end of cone 17 is equipped with several upper elastic grooves 20, and upper elastic groove 20 is axially extended to 18 position of lower cone；The lower cone
The free end of body 18 is equipped with several lower elastic grooves 21, and lower elastic groove 21 is axially extended to 17 position of upper cone；The upper cone
17 minimum outer diameter is less than the internal diameter of mounting hole 7, and maximum outside diameter is greater than the internal diameter of mounting hole 7；Shape in the locking screw mother set 13
At cavity 24, the inclined-plane 22 for matching corresponding lower cone 18 is provided in cavity 24；The internal diameter of the axis hole 16 is greater than or equal to
11 outer diameter of middle section of screw tap 9；The length of the lower cone 18 is less than the length of upper cone 17.
The upper elastic groove 20, lower elastic groove 21 are in be spaced apart.
Gripping sleeve 8 is that boundary line is divided into upper cone 17 and lower cone 18 with annular groove 19, by the effect of annular groove 19, upper cone
17, the elastic bearing strength that suffers oppression of lower cone 18 is bigger, and whole elastic property improves, in addition, upper elastic groove 20 and lower bullet
Property slot 21 development length, and interval setting, so that upper cone 17 and lower cone 18 form multiple elastic monomers, elasticity is single
The elastic effect of body is more preferably.
The use principle of the utility model is as follows:
The magnetic tooth machining unit of the utility model first back-outs locking screw mother set 13 when installing screw tap 9, by gripping sleeve 8
Lower cone 18 be directed at 13 cavity 24 of locking nut, and the whole insertion mounting hole 7 of related locking nut 13, at this point, gripping sleeve 8
A part of upper cone 17 is in mounting hole 7, and 13 twist-on of locking nut is in the lower end of rotary shaft 5, slightly rotation to locking
Nut 13 is not fallen, and then screw tap 9 is packed into gripping sleeve 8, until gripping sleeve 8 is clamped to 11 circular shaft of middle section of screw tap 9
Part continues thereafter with and screws locking screw mother set 13, with constantly screwing for locking screw mother set 13, the inclined-plane in locking screw mother set 13
22 squeeze the outer peripheral surface of lower cone 18, and at the same time, the inner face of locking screw mother set 13 squeezes gripping sleeve 8 axially towards installation
It is moved in hole 7, finally, inclined-plane 22 makes lower cone 18 inwardly shrink clamping screw tap 9, and upper cone 17 is pressed against by mounting hole 7
Contract clamps screw tap 9, reaches pretensioning effect.Since required clamping force is larger, locking nut 13 finally is directed at using wrench 23
Two opposite of hexagonal, rotating spanner 23 completes to fix to clamp work to screw tap 9 to tight.
The cavity 24 of locking screw mother set 13, inclined-plane 22 dimensions have it is a variety of, to be generated to gripping sleeve 8 different
Clamping force, to make the screw tap 9 of the clamping different size of gripping sleeve 8.
The upper elastic groove 20 of the upper cone 17 of gripping sleeve 8 extends to lower cone 18, and the lower elastic groove 21 of lower cone 18 extends
To upper cone 17, this makes, and gripping sleeve 8, can be sensitiveer when the nut set 13 that is locked squeezes, and clamp speeds faster, are pressed from both sides
Clamp force is bigger.
In use, selecting a workbench 25 first, this 25 mesa material of workbench is ferrimagnet, then by pedestal
1 is placed on workbench 25, and by the rotation of switch 14 to " ON ", at this point, the magnetic of magnet base is opened, pedestal 1 is adsorbed on workbench
On 25, to complete the fixation of magnetic tooth machining unit, the magnetism of magnet base is siphoned away by foreign object in order to prevent causes adsorption capacity to reduce, special
Other, using the magnetic material of high-intensitive isolation as pedestal 1 and support arm 2 manufacture material, later, we are just able to rotate rotation
Axis 5, while rotary shaft 5 is pushed, move down rotary shaft 5 constantly along axial direction while rotation, to realize spiral shell to work piece
Line processing.
Due to using magnet base as the fixed structure adsorbed, so, the magnetic tooth machining unit of the utility model can will be whole
Body laterallys secure, and successfully can also carry out tapping to work piece.
