Detailed Description
The technical solution of the present invention is further specifically described below by way of examples with reference to fig. 1-2.
As shown in fig. 1-2, the present embodiment provides a novel screwing device, which includes a motor device 1, a first worm wheel 2, a second worm wheel 5, a housing 3 and a screwdriver head 4.
The motor device 1 is L-shaped and convenient to hold, and a driving motor is arranged in the motor device 1 and used for providing power for the screwdriver head 4. The output end of the motor device 1 is provided with a clamp for connecting a coupler. One end of the coupler is connected with the motor device 1, and the other end of the coupler is provided with a first spline and connected with a first worm wheel 2; the center of the first worm wheel 2 is provided with a first spline groove for connecting with a coupler. The first worm wheel 2 and the coupling can also adopt an integrated design structure, and the direct drive of the motor device 1 to the first worm wheel 2 is realized.
The second worm wheel 5 is matched with and vertical to the first worm wheel 2 to realize 90-degree reversing, and a second spline groove is formed in the center of the second worm wheel 5 and used for connecting the screwdriver head 4 and realizing synchronous rotation.
The two ends of the screwdriver head 4 are respectively provided with a cross screwdriver head and a straight screwdriver head, the middle part of the screwdriver head is provided with a second spline, and the second spline is matched with a second spline groove of the second worm wheel 5, so that the screw driving device can realize the reversing of +/-90 degrees.
The first worm wheel 2 and the 5 outsides of second worm wheel are equipped with shell 3 of cuboid form, 3 inner structure of shell are used for supporting and fixed first worm wheel 2 and second worm wheel 5 to set up the trompil for shaft coupling and screwdriver head 4 respectively, the trompil size respectively with shaft coupling and screwdriver head 4 phase-match, and maintain shaft coupling and the stable rotation of screwdriver head 4, the diameter that is used for installing two holes of screwdriver head 4 all is less than second spline cross sectional dimension, make the second spline can fix in shell 3, avoid axial float.
This novel beat screw device concrete theory of operation does:
after electrifying the electric device 1, the motor drives the first worm wheel 2 to rotate through the coupler, the first worm wheel 2 is matched with the second worm wheel 5, the rotation is transmitted to the screwdriver head 4, the screwdriver head 4 is aligned to a screw which needs to be screwed or loosened, and the reversing and the quick screwing are realized.
Although the present invention has been described in connection with the preferred embodiments, the embodiments are not intended to limit the present invention. Any equivalent changes or modifications made without departing from the spirit and scope of the present invention also belong to the protection scope of the present invention. The scope of protection of the invention should therefore be determined with reference to the claims that follow.
