Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a stop ring insertion tool for inserting an E ring or the like, which is a stop ring, into an object to be inserted.

(Prior Art) Conventionally, as this type of insertion tool, in a washer inserter that pushes out a single washer from a washer guide in which a large number of washers are stacked and inserts the washer into an object to be inserted. A receiving plate having a plate thickness smaller than the thickness of the washer is provided on the lower surface of the fixing table to which the washer guide is attached, and an inserter for pushing out the washer is slidably provided between the receiving plate and the fixing table. It is known that the inserter is arranged and the insert is made into a flexible thin plate (see, for example, Japanese Utility Model Laid-Open No. 59-42827).

(Problems to be solved by the invention) In the conventional technique, a washer guide and a fixing base with a washer guide are formed at the tip of the tool, so that the washer may change depending on the shape of the object to be inserted or the place where the washer is inserted. There is a problem that the guide cannot interfere with the object to be inserted and the tool cannot be used.

The present invention has been made in view of the above problems of the conventional technique, and an object of the present invention is to make it possible to easily insert a stop ring into an object to be attached and to provide a stopper with good workability. It is intended to provide a ring insertion tool.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a retaining ring insertion tool for inserting a retaining ring into an object to be inserted, and fixing a guide for stacking a plurality of retaining rings at one end. A grip portion is provided in which a holder having a long hole formed at the other end is slidably and rotatably connected to the long hole via a pin, and recesses for holding a retaining ring are formed at both ends of the holder.

(Operation) According to the present invention configured as described above, when the stopper ring sandwiched between the one recesses of the holder is inserted into the insert, the other recessed portion of the holder simultaneously sandwiches the stopper rings stacked on the guide. , Further pull the holder out of the object to be inserted 180
The same operation can be repeated by rotating the same degree.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partially exploded perspective view of a retaining ring insertion tool according to the present invention.

The retaining ring insertion tool is long enough to be held by human hands,
It is composed of a handle portion 1 having a width, a guide 3 for accommodating a large number of E-rings 2 which are stop rings and accommodating them, and a holder 5 having recesses 4 at both ends for holding the stop rings.

The guide 3 has a plurality of rod-shaped grooves 6 that engage with the E-ring 2 in the axial direction, and the lower end is screwed and fixed to one end of the handle 1. Further, the stopper 7 is provided on the upper end of the guide 3.
Is screwed in and fixed, and as shown in FIG. 4, the lower end of the stopper 7 and the E-ring 2 stacked on top
The coil spring 8 is compressed between and.

Further, since the concave portion 4 of the holder 5 forms a stepped portion 4a as shown in FIG. 1 in the lower portion of the guide 3, a receiving plate 9 is provided at a portion where the upper surface of the handle portion 1 and the guide 3 are in contact with each other. A circular guide 10 is formed in the upper part so that only the E-ring 2 held by the holder 5 can be removed.

The holder 5 is formed with a long hole 11 and the long hole 11 and the concave portion 4 in the vicinity of the concave portion 4 so that a concave portion 4 for holding the E ring 2 is formed at both ends and an elastic force acts when the concave portion 4 holds the E ring 2. A groove 12 is formed therethrough. Further, a long hole 13 is formed in the center of the holder 5, and a pin 14 is screwed into the handle portion 1 through the long hole 13 at a portion opposite to the portion of the handle portion 1 to which the guide 3 is fixed. The holder 5 is slidably and rotatably connected to the handle 1.

Reference numeral 15 is a retractable positioning guide that restrains the relative positions of the handle portion 1 and the holder 5 with moderation.

The operation of the retaining ring insertion tool configured as described above will be described below.

FIGS. 2 to 4 show a state in which the operator holds the insertion tool and inserts the E-ring 2 into the object to be inserted (not shown). That is, when the E-ring 2 held in the recess 4 on the object to be inserted is inserted into the object to be inserted, the holder 5 slides to the guide 3 side by the elongated hole 13, and the recess 4 on the guide 3 side also moves to the guide 3. Hold the E-ring 2 stacked at the bottom.

Next, pull the handle part 1 away from the object to be attached
4 presses the inner peripheral surface of the elongated hole 13 of the holder 5, and the holder 5 is also pulled out in a direction away from the object to be inserted. As a result, one of the E-rings 2 is detached from the recess 4 while being inserted into the object to be inserted, and the other of the E-rings 2 engaged with the circular guide 10.
Is clamped in the recess 4.

Further, as shown in FIG. 5, the holder 5 is rotated 180 degrees about the pin 14 as a fulcrum, and the elongated hole 11 and the positioning guide 15 are engaged with the concave portion 4 not holding the E ring 2 at a position facing the guide 3. And position it.

Then, the E-ring 2 on the side of the object to be inserted is inserted into the object to be inserted into the state shown in FIG. Similarly, the above operation can be repeated to perform the work of inserting the E-ring 2.

In the present embodiment, the E-ring 2 is used as the stop ring, but it goes without saying that it can be applied to a C-ring, a U-ring, and the like.

(Effects of the Invention) As described above, according to the present invention, the guides for stacking a large number of retaining rings do not interfere with the object to be inserted and can be applied to any insertion position.

Further, since the other recess of the holder clamps the stop ring at the same time when the stop ring is inserted into the object to be inserted in one operation, the workability can be improved.
