- the device proposed in Patent Document 1 as an apparatus for automatically fitting the C-shaped clip includes an extrusion cylinder, a positioning cylinder, and a fitting cylinder, and includes one C-shaped clip held in the holder. Pushing diagonally in the cylindrical member with the diameter reduced by the extrusion cylinder, then lowering the cylindrical member by the positioning cylinder to contact the piston, and further engaging the clip in the annular groove with the fitting cylinder I have to.
- a cylinder containing parts is disposed obliquely, a spiral bar that is rotated by a motor is provided in the cylinder, and the cylinder is rotated as the spiral bar rotates.
- Upper end opening force Supply parts one by one.
- the slider is disposed obliquely and a stagger is provided at the lower end of the slider so that the parts sliding down the slider are separated one by one by the strobe.
- Patent Document 1 Japanese Patent Laid-Open No. 9-225754
- Patent Document 2 Japanese Patent Laid-Open No. 9-135099
- Patent Document 3 Japanese Patent Laid-Open No. 2003-175425
- Annular workpieces such as C-shaped clips and piston rings are often thin and thin. Also in some cases, oil and wrinkle-preventing agents are attached to these workpieces, and in a cartridge or the like in which a large number of annular workpieces are bundled, the annular workpieces are attached to each other. ! /
- an annular workpiece cutting device includes a guide rod on which a large number of annular workpieces are slidably loaded on an outer peripheral portion, and an opening through which one end of the guide rod passes.
- the annular work is urged in the direction of the separation plate along the guide rod by the urging means, and the separation plate is reciprocated by the driving means in the radial direction of the guide rod,
- the width of the opening of the separation plate is larger than the outer diameter of the guide rod and smaller than the outer diameter of the annular workpiece.
- a wedge portion is provided on the inner peripheral surface of the opening, and the separation plate is guided by the guide plate. By moving in the radial direction of the rod, the wedge portion is inserted between the most advanced annular workpiece and the next annular workpiece to separate the most advanced annular workpiece.
- a step portion is provided on the inner peripheral surface of the opening to contact the state-of-the-art annular workpiece.
- the thickness of the stepped portion is set to a thickness at which the tip of the wedge member is positioned between the annular work abutting and the next annular work.
- the annular workpiece can be smoothly fed to the separating portion from the beginning to the end.
- FIG. 1 is a front view of an annular workpiece cutting device according to the present invention.
- Figure 2 Enlarged side view from the direction A in Figure 1
- FIG. 7] (a) to (c) are diagrams illustrating the operation of the clipping device.
- FIG. 8 Diagram explaining the action of the C-clip mounting jig as an annular workpiece
- FIG. 1 is a front view of an annular workpiece cutting device according to the present invention
- FIG. 2 is an enlarged side view seen from the direction A in FIG. 1
- FIG. 3 is a front view of a separating plate that forms part of the cutting device
- FIG. Fig. 3 is a cross-sectional view taken along the line B-B in Fig. 3
- Fig. 5 is a rear view of the separating plate that forms part of the cutting device.
- it is fitted as an annular workpiece into the piston pin mounting hole for retaining.
- the shape clip will be described.
- a rail 2 is provided horizontally on a base 1, a guide rod 3 that is also a pipe material is disposed above the rail 2, and a moving body 4 is provided on the rail 2.
- the movable body 4 is provided with an upright piece 5 extending upward.
- a constant load panel 7 is provided between the moving body 4 and the support plate 6 attached to the base 1, and the moving body 4 is urged to the right side in the figure with a constant force.
- a V-shaped guide plate 8 is attached to the tip of the support plate 6, and a shaft portion of a C-clip mounting jig is placed on the guide plate 8. In this way, centering can be performed.
- the distal end portion (right end in FIG. 1) of the guide rod 3 penetrates the separation plate 9, and a ring member 10 is slidably mounted on the outer periphery of the guide rod 3.
- the upright piece 5 of the moving body 4 is in contact with the rear end (left end).
- the urging force of the constant load panel 77 is applied to the C-shaped clip W group via the moving body 4 and the ring member 10, and the C-shaped talp W group is urged to the right side in the figure and is located at the rightmost end.
- the leading C-shaped clip W contacts the separation plate 9 with a constant load.
- the separating plate 9 is bolted to the bifurcated connecting portion 12 of the cylinder unit 11 fixed to the base 1. It is attached at 13 so that its position can be adjusted, and can be reciprocated in the vertical direction by driving the cylinder unit 11.
- the shape of the separating plate 9 is rectangular when viewed from the front, and an elliptical (ellipsoidal) opening 14 is formed in the center, and the width of the opening 14 is The dimension tl is set larger than the outer diameter of the guide rod 3 and smaller than the outer diameter of the C-shaped clip W.
- a step portion 15 and a wedge portion 16 are formed on the left and right side surfaces of the inner circumferential surface of the opening portion 14 that are linear.
- the distance t2 between the outer edges in the width direction of the left and right step parts 15, 15 is a C-shaped clip.
- the thickness t3 of the stepped portion 15 is such that the leading end (lower end) of the wedge portion 16 is the leading C-shaped clip with the leading C-shaped clip W in contact with the stepped portion 15.
- the dimension is set between W and the next C-shaped clip W.
- FIG. 6 is a diagram showing another embodiment of the separation plate 9.
- the opening 14 is not closed and has a shape opened upward. Further, the opening 14 may have a shape opened downward.
- the shaft 101 at the tip of the mounting jig 100 is positioned by the guide plate 8, and the shaft 101 is inserted into the inner hole of the guide rod 3. Then, by operating the lever 102, a part of the C-shaped clip W separated between the tip shaft portion 101 and the clamp member 103 is pressed and cut out.
- a procedure for attaching the C-shaped clip to the annular groove of the piston mounting hole using the mounting jig 100 in which the C-shaped clip W is set will be described with reference to FIG.
- the shaft portion 101 is inserted into the piston pin mounting hole 104 of the piston.
- the lower end portion of the C-shaped clip W is fitted into the annular groove 105.
- the lever 102 is released to release the holding state by the clamp member 103 and the shaft 101 is further advanced, the remaining portion of the C-shaped clip W is pushed into the annular groove 105.
- the worker holds the mounting jig 100 by hand and cuts out the C-shaped clips one by one.
- a loading jig setting device is arranged adjacent to the cutting device. Install it so that the C-shaped clip is automatically set on the mounting jig 100.
- the annular workpiece cutting device according to the present invention can be used in a process of mounting a C-shaped clip in an annular groove of a piston pin mounting hole.
