Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a spring spring mounting apparatus for a fastener magazine mounted on a fastening machine such as a nailing machine, and more particularly, to a spring spring mounting apparatus for a fastener magazine that facilitates assembly.
[0002]
[Prior art and problems to be solved by the invention]
In a fastening machine such as a staple driving machine or a nail driving machine, a fastener magazine connected to the nose part of the fastening machine is provided with a spring-driven pusher, and the staple or nail is pushed forward by the pusher and supplied to the nose part. Is widely used.
[0003]
The fastener magazine is composed of a guide rail for guiding fasteners (nails or staples), a pusher, and a spring, and the inner peripheral end of the mainspring is fixed to the pusher, and the outer peripheral end is connected to the front portion and the nose portion of the fastener magazine. The pusher is always urged forward by the spring force of the mainspring spring, and the fastener on the guide rail is pumped forward by the pusher.
[0004]
At the time of manufacturing the fastening machine or when reattaching the fastener magazine removed to replace the spring, it is formed at the tip by pulling the tip of the outer periphery of the spring mounted on the pusher forward. Align the holes with the bolt holes at the front of the fastener magazine, and align these two holes with the bolt holes at the nose of the fastening machine. Insert the bolts into the three holes and screw them. That is, there is a problem that it is difficult to assemble the fastener magazine and the spring spring because it is necessary to hold the fastener magazine while pulling the spring spring, align the three holes, and insert the bolt.
[0005]
Therefore, a technical problem to be solved in order to facilitate the assembly of the fastener magazine to the fastening machine arises, and the present invention aims to solve the above problem.
[0006]
[Means for Solving the Problems]
The present invention is proposed to achieve the above object, and is a fastener magazine which is coupled to a nose portion of a fastening machine such as a nail driving machine or a staple driving machine with a bolt, and is a fastener such as a nail or a staple. Guide spring, a pusher that can slide back and forth along the guide rail, and a spring spring interposed between the pusher and the front portion of the guide rail. The spring is applied to the front end of the guide rail by the spring force of the spring. In the fastener magazine, the mainspring spring locking tool has claws at both front and rear ends, and a bolt hole is formed in the center, and the length in the front and rear direction is behind the bolt hole formed at the front of the guide rail. a hole provided over the front claw portion of the spiral spring fastener guide rail to the front edge, a rear claw portion is inserted into the elongated hole, Zenma When the spring locking tool is overlaid on the guide rail, the bolt hole of the guide rail and the bolt hole of the mainspring spring locking tool are formed to coincide with each other, and the inner peripheral side end of the spring spring is locked to the pusher. The locking hole formed on the outer peripheral side end of the mainspring spring is engaged with the rear claw portion of the mainspring spring locking tool, and the bolt hole of the guide rail and the bolt hole of the mainspring spring locking tool and the bolt hole of the nose portion are formed. Provided is a spring spring mounting device for a fastener magazine configured such that the tip end of the spring spring is fixed by matching and inserting the bolts into the three bolt holes to join the guide rail and the nose portion. .

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. 1 shows a nose portion of a nailing machine, FIG. 2 is a sectional view taken along line AA in FIG. 1, FIG. 3 is a sectional view taken along line BB in FIG. A nose portion 2 is attached to a front end opening (not shown), and 2 is a nail magazine.
[0008]
A nail magazine 2 coupled to a nose portion 1 by bolts and nuts on the back side of FIG. 1 comprises a guide rail 3, a pusher 4 and a spring 5 that guide the nail, and the guide rail 3 is rearward (right in FIG. 1). ) Extending diagonally upward. Although not shown, the upper surface of the rear half of the guide rail 3 is open, and the pusher 4 is manually retracted so that the connecting nail N is loaded into the guide rail from above.
[0009]
FIG. 4 shows the spring spring locking tool 6, the front shape of which is a trapezoid that matches the shape of the tip of the guide rail 3 of the nail magazine 2, the bolt hole 7 is formed at the center, and a square detent washer. The upper and lower sides are bent at right angles to form claw portions 8 and 9, and the left and right sides are also formed with claw portions 10 and 11 that are bent at right angles. Among these, the claw portion 11 on the left side which is the rear side is press-molded in a crescent shape, and is used as a spring locking claw to be inserted into a round hole 5 a formed in the distal end portion of the mainspring spring 5.
[0010]
As shown in FIGS. 3 and 5, a bolt hole 12 is formed at the tip of the guide rail 3 of the nail magazine 2, and a long long hole 13 is provided in the front and rear thereof, and the spring of the mainspring spring locking tool 6. If the locking claw 11 is inserted into the elongated hole 13 and the upper and lower and front (right) claw portions 8, 9, 10 are engaged with both the upper and lower sides and the front end side of the guide rail 3, the bolt of the spring spring locking tool 6 The hole 7 and the bolt hole 12 of the guide rail 3 coincide with each other, and the spring spring locking tool 6 cannot be rotated.
[0011]
When assembling the nail magazine 2 to the nose portion 1 of the nailing machine, the pusher 4 of the nail magazine 2 is slid to the front end of the moving range, and the tip of the mainspring 5 attached to the pusher 4 is pulled forward. As shown in FIG. 6, the spring locking claw 11 of the mainspring spring locking tool 6 is inserted into the elongated hole 13, and the spring locking claw 11 is inserted into the round hole 5 a of the mainspring spring 5.
[0012]
Then, by pulling the spring spring locking tool 6 forward (right side) and engaging the upper and lower and right claw portions 8, 9, and 10 with both the upper and lower sides and the front end side of the guide rail 3, the spring spring 5 is tensioned, Moreover, the bolt hole 7 of the spring spring locking tool 6 and the bolt hole 12 of the guide rail 3 match. In this state, the nail magazine 2 is held and the bolt holes 7 and 12 of the guide rail 3 and the spring spring locking tool 6 are aligned with the bolt holes 1a of the nose portion 1 of the nailing machine as shown in FIG. When the bolt 14 is inserted and the bolt 14 and the nut 15 are fastened, the nail magazine 2 is coupled to the nose portion 1 of the nailing machine.
[0013]
The present invention is not limited to the above-described embodiment, and various modifications are possible within the technical scope of the present invention, and it is natural that the present invention extends to those modifications.
[0014]
【The invention's effect】
As described above, according to the spring spring mounting device of the fastening machine of the present invention, the tip of the spring spring for driving the pusher can be locked and fixed to the front portion of the fastener magazine. When attaching, align the bolt hole of the nail magazine and the bolt hole of the nailing machine and tighten the bolt, and pull the spring spring to pull the spring spring hole, the bolt hole of the nail magazine and the bolt hole of the nailing machine Compared to the conventional procedure in which the three holes are aligned and the bolt is inserted, the assembly is very easy, and the workability of manufacturing and maintenance is remarkably improved.
