Description

Oblique row nail shooting striking tool

Technical Field

The utility model relates to a nail gun, in particular to an oblique-row nail shooting striking tool, and belongs to the technical field of electric tools.

Background

When the fastener striking tool such as an electric air spring nail gun works, a piston in a cylinder body is driven by compressed air power to drive a striker to drive a nail into a workpiece, and the tool is a tool commonly used in industries such as construction, decoration and the like, and the typical structure is disclosed in Chinese patent literature with the name of a power type fastener driver with the application number 202180025167.1, and comprises an energy storage mechanism consisting of the cylinder body and the piston in a shell, wherein a telescopic gun nozzle is arranged at the front end of a nailing seat, and a nail box is arranged at one side of the nailing seat; one side of the cylinder body is provided with a grab handle with a battery pack, one side of the gun nozzle is provided with a nail box, and the nail box is provided with a nail pusher for pushing the row nails to a nailing seat; an electric lifting mechanism for driving the piston to compress and store energy is arranged between the grab handle and the nail box, the lifting mechanism comprises a driving wheel meshed with the firing pin, and the driving wheel is in transmission connection with a motor for providing electric energy for the battery pack. When the gun nozzle is pressed down, the motor is started, the striker is driven by the lifting mechanism to drive the piston to compress air from the temporary locked preparation position, and after the striker is separated from the engagement with the lifting mechanism, the striker is released suddenly to drive the row nails of the nailing seat in the nailing box, so that the row nails are ejected from the gun nozzle.

The driving axis determined by the piston of the fastener striking tool and the symmetrical center plane of the grab handle are usually in the same vertical plane, so that the projection of the nail conveying direction of the nail box (also called a box and a nail groove) on the vertical plane is inclined with the driving axis (usually 60-80 degrees refer to fig. 1) to form an inclined row nail gun structure. Moreover, in order to avoid interference of the motor reducer power mechanism with the magazine, with the output axis immediately adjacent to the vertical plane (typically less than 30mm apart), the projection of the magazine perpendicular to the vertical plane is also skewed to one side (typically about 10 ° -30 ° -see fig. 2).

As a result, the drive teeth on the striker are correspondingly deflected from the striker body (see angle a in fig. 24 of 202180025167.1) and the striker tip is offset from the striker body (see offset B in fig. 7 of 202180025167.1) to ensure maximum contact area with the tip of the striker when a staple is struck into the staple channel. In addition, the assembly structure of the nailing seat and the installation position of the frame also need to be adaptively deflected and inclined, so that the manufacturing cost is increased due to the complicated structure, the development of series products on the original basis is not facilitated, and the stress state of the firing pin is poor and is easy to damage. In addition, the projection of the nail box in the prior art perpendicular to the plumb plane deflects to one side, so that the width of the whole machine is obviously increased, the center of gravity deviates from the symmetrical center plane of the grab handle, and the operation and control are not facilitated.

Detailed Description

Example 1

As shown in fig. 1 to 4, the basic structure of the oblique nail striking tool of this embodiment is that an energy storage mechanism 2 composed of a cylinder and a piston 2.1, a striking mechanism 3 composed of a telescopic gun nozzle 3.2 of a front-end nailing seat 3.1, a nailing mechanism 8 composed of a striker 8.1 connected with the piston 2.1 and extending to the gun nozzle 3.2, a lifting mechanism 4 composed of a driving wheel driven by a motor engaged with the striker, a nail feeding mechanism 5 composed of a nail magazine obliquely mounted on the nailing seat side, and a power mechanism 6 composed of a motor gear box located between the handle and the nail magazine are arranged in a housing 1 with a grip, and the power mechanism 6 is in driving connection with the lifting mechanism 4 through a power conversion mechanism 7. The energy storage mechanism 2, the striking mechanism 3, the nailing mechanism 8 and the lifting mechanism 4 are disclosed in Chinese patent document 202123051528.6.

In order to avoid operational interference, the extension direction of the magazine is projected in a lower end backward tilting shape on a vertical plane parallel to the movement direction of the striker and the axial direction of the motor. Specifically, the magazine feeding direction of the staple feeding mechanism 5 is projected on a vertical plane parallel to the striker moving direction and the motor axial direction, which are defined by the piston driving axis D, and inclined at about 70 ° to the driving axis. As shown in fig. 2 and 3, in order to facilitate the holding operation and to avoid the interference between the nail feeding mechanism 5 and the power mechanism 6, the magazine of the nail feeding mechanism 5, together with the nailing mechanism 8 and the striking mechanism 3, and the lifting mechanism 4, are deviated by about 20 ° toward the side of the motor reducer power mechanism 6 output axis M1 parallel to the vertical plane, forming a magazine center line M2 and a lifting mechanism center line M3.

In this case, in order to keep the parts of the striking mechanism 3, the lifting mechanism 4, the nail conveying mechanism 5 and the power mechanism 6 as universal as possible with the original series products, and avoid complex structure and increase of processing and assembling cost, an innovative design power conversion mechanism 7 shown in fig. 4 is adopted, and a fork-shaped coupling input rotating block 7.1 supported by a lower bearing 7.4 in the power conversion mechanism 7 is fixedly connected with a rotating output end of a motor of the power mechanism 6 after being decelerated by a planetary gear reducer, and is hinged with one of the hinge holes of a cross hinge block 7.2 through a first pin, and the hinge hole of the cross hinge block 7.2 is hinged with a reverse fork-shaped coupling output rotating block 7.3 supported by an upper bearing 7.5 through a second pin, so as to form a universal coupling structure. The rotating shaft of the coupling output rotating block 7.3 is fixedly connected with the rotating shaft of the driving wheel 4.1 supported on the frame 4.2 by the lifting mechanism 4. Therefore, even if the nail box of the nail conveying mechanism 5, the nailing mechanism, the striking mechanism and the lifting mechanism form an included angle with the axial line of the rotary output end of the power mechanism due to deflection towards one side, the smooth transmission of the rotary power to the lifting mechanism can be ensured.

Compared with the prior art, the embodiment has the advantages that the coupler power conversion mechanism is used, so that the firing pin is kept in an ideal stressed state, the contact area between the head of the firing pin and nails is large, the long-term stability of nailing operation is facilitated, a large number of universal parts can be adopted, and the design development period and the processing and manufacturing cost of the inclined chain riveting gun are reduced.

Example two

The basic structure of the oblique staple striking tool of this embodiment is shown in fig. 5 and 6, and the basic structure is the same as that of the first embodiment, except that: the motor shaft is parallel to the extending direction of the nail box. Therefore, the nail box of the nail conveying mechanism 5, the nailing mechanism 8, the striking mechanism 3 and the lifting mechanism 4 do not need to deflect towards one side of the output axis M1 of the motor reducer power mechanism 6 parallel to the plumb plane, the interference between the nail conveying mechanism 5 and the power mechanism 6 can be avoided, and the projection of the nail box perpendicular to the plumb plane does not need to deflect towards one side, so that the oblique-row nail shooting striking tool of the embodiment has the advantages of narrow width, compact structure and convenience in operation and control.
