Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-3, a screw positioning device on screw gun, including installation sleeve 5 and screw 8, 5 top elastic sliding installs screw gun 4 in the installation sleeve, holding ring 1 is installed to 5 bottoms of installation sleeve, 5 internally mounted of installation sleeve has elastic support column 3, 3 outside sliding mounting of elastic support column have be used for right screw 8 carries out spacing fixed elastic positioning claw 2, 2 surfaces of elastic positioning claw are provided with sliding tray 201, 3 sliding mounting of elastic support column be in the sliding tray 201, the inside support frame 7 that is provided with of installation sleeve 5, install in the support frame 7 outside will elastic positioning claw 2 to the spring leaf 6 that screw 8 elasticity compressed tightly.

In this embodiment, a tension spring 9 is installed between the elastic support column 3 and the inner wall of the top of the sliding groove 201.

In this embodiment, the elastic positioning claws 2 are at least provided in two groups and are uniformly arranged outside the screw 8.

In this embodiment, the elastic positioning pawl 2 includes a claw portion 202 and a connecting portion 203, the connecting portion 203 is integrally formed with the claw portion 202, and the sliding groove 201 is located in the connecting portion 203.

In this embodiment, a clamping groove for facilitating the clamping of the screw 8 is formed at the bottom of the clamping claw portion 202.

In this embodiment, the elastic support column 3 includes the cylinder 302, cylinder 302 slidable mounting is in the sliding tray 201, fixed sleeve 301 is installed in the cylinder 302 outside, fixed sleeve 301 inner wall with install torsional spring 303 between the connecting portion 203, torsional spring 303 with connecting portion 203 sliding connection, torsional spring 303 with fixed sleeve 301 fixed connection, torsional spring 303 suit is in the cylinder 302 outside.

In this embodiment, a limiting cap 304 is installed at the end of the column 302 penetrating through the sliding groove 201.

In this embodiment, the positioning ring 1 is an elastic ring.

In this embodiment, the positioning ring 1 is connected to the mounting sleeve 5 through an elastic connecting piece.

When the screw 8 is sleeved in the positioning ring 1, the head of the screw 8 is positioned between the clamping grooves at the bottom of the clamping claw part 202 of the elastic positioning claw 2, the tail of the screw 8 is positioned in the positioning ring 1, when the screw gun 4 works, the screw gun 4 moves downwards in the mounting sleeve 5 until the output end is connected with the head of the screw 8 and drives the screw 8 to move downwards, in the moving process, the spring leaf 6 at the outer side of the support frame 7 always keeps a compression state on the elastic positioning claw 2, the elastic positioning claw 2 elastically limits the head of the screw 8, when the screw gun continuously moves downwards, the elastic positioning claw 2 overcomes the elastic force of the tension spring 9 and moves downwards under the guiding action of the elastic support column 3 and the sliding groove 201, at the moment, the clamping claw part 202 overcomes the torsion force of the torsion spring 303, rotating around the column 302, keeping the elastic limit of the screw 8 until the elastic positioning claw 2 contacts with the positioning ring 1, continuing to move downwards, moving the screw 8 to a slot at the bottom of the clamping claw part 202 separated from the elastic positioning claw 2 and the positioning ring 1, thus completing the installation of the screw 8, precisely installing the screw 8 at a specified position through the limit positioning of the elastic positioning claw 2 and the positioning ring 1, after the installation of the screw 8, because the screw gun 4 is elastically and slidably connected with the installation sleeve 5, the screw gun 4 elastically retreats, the clamping claw part 202 rotates around the column 302 under the torsion of the torsion spring 303 and the elastic force of the spring plate 6 to the original position, and the elastic positioning claw 2 lifts to the original position under the elastic force of the tension spring 9 and the spring plate 6, the next operation can be performed.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
