Fig. 4 is the sectional view of impact head 110 in electric impacting head provided in this embodiment；Fig. 5 is provided in this embodiment
The structural schematic diagram of transmission shaft 120 in electric impacting head.Please refer to Fig. 4 and Fig. 5, in the present embodiment, 120 company of being set to of transmission shaft
It connects in hole 111 and the outer wall of transmission shaft 120 is provided with the first driving groove 121, the inner wall of connection through-hole 111 is provided with and first
Corresponding second driving groove 116 of driving groove 121, ball 140 are set in the first driving groove 121 and the second driving groove 116.
Wherein, the first driving groove 121 is corresponding with the second driving groove 116 refers to the first driving groove 121 and the second driving groove 116
Shape it is consistent, notch direction is opposite, to enable ball 140 that the first driving groove 121 and the second driving groove to be arranged in simultaneously
It in the first driving groove 121 and rolls in 116 and in the second driving groove 116.
Transmission shaft 120 includes interconnecting piece 122 and transmission shaft body 123, and one end of transmission shaft body 123 is set to interconnecting piece
122, the other end of transmission shaft body 123 passes through connection through-hole 111.The one end for being driven the separate interconnecting piece 122 of shaft body 123 is set
It is equipped with the first driving groove 121, the second driving groove 116 is located at the inner wall of the connection through-hole 111 at the first impact head 1141, due to the
Fluted 113 are arranged at two impact heads 1142, so, the second driving groove 116 is set at the first impact head 1141, the second transmission
Slot 116 is set to one end of the notch of the separate groove 113 of the inner wall of connection through-hole 111.
A part of ball 140 is located in the first driving groove 121, and a part is located in the second driving groove 116, makes ball
140 can be rolled in the structure that the first driving groove 121 and the second driving groove 116 are formed, and realize impact.
In the present embodiment, output shaft 160 and transmission shaft 120 are coaxially disposed, and output shaft 160 is made to be applied to protrusion impact block
The effect of 112 power is more preferable.
First driving groove 121 has interconnected first end 1211, second end and connecting pin 1213,1211 He of first end
Second end is symmetrical arranged relative to connecting pin 1213, and the separate protrusion of first end 1211 and second end towards connecting pin 1213 rushes
The one end for hitting block 112 extends.
Correspondingly, the shape of the second driving groove 116 is consistent with the shape of the first driving groove 121, makes ball 140 while being arranged
In the first driving groove 121 and the second driving groove 116, increase the stroke of ball 140, to increase impact torsion.
First end 1211, connecting pin 1213 and the equal rounding off of second end, enable ball 140 in the first driving groove 121
It is rolled in the second driving groove 116, the stroke of ball 140 is longer, and impact torsion is big.
In the present embodiment, ball 140 is steel ball, and the first driving groove 121 is the first steel bead groove, and the second driving groove 116 is the

Hole 111 is connected to be set in rolling bearing 150.
Transmission shaft 120 is made by the setting of rolling bearing 150 since a protrusion impact block 112 being arranged on impact head 110
In the rotation with impact head 110, biggish centrifugal force will not be generated, keeps its impact effect more preferable.
The work of electric impacting head provided by the embodiment of the utility model, electric impact screw batch and electric impact wrench is former
Reason are as follows:
One end of the separate transmission pin block 162 of output shaft 160 is applied using screw trundle or spanner trundle straight
The power in line direction moves output shaft 160 towards the direction of impact head 110, the transmission impact protrusion impact block 112 of pin block 162, punching
Tap the head 110 and transmission shaft 120 rotate together and, ball 140 rotates in the first driving groove 121 and the second driving groove 116, thus
So that impact head 110 is directed away from the direction movement of output shaft 160, compresses compressed spring 130, in screw trundle or spanner
After the power that trundle applies terminates, due to the rebound of compressed spring 130, pass ball 140 in the first driving groove 121 and second
Rotation in dynamic slot 116, impact head 110 are moved towards the direction of output shaft 160, make to protrude the impact transmission pin block of impact block 112
162.Impact stroke is larger, has bigger impact torsion.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
