The operation of the groove deburring device according to the present invention will be described. As shown in FIG.
To the workpiece W ₁ is set, as shown in FIG. 2, the engaging pin 1 forming the workpiece positioning unit U ₂
0 moves back and forth, entire positioning unit U ₂ is by being rotated, the work W ₁ is positioned with respect to a number of the blade body 7 constituting the blade head H. In this state, the workpiece fixing unit U _3, the workpiece W ₁ is fixed in its position.

[0016] Next, as shown in FIG. 6, lowers the blade head H in the raised end position, is disposed in the neutral position (state in which the respective blade 7 twice force F ₂ is not applied) each blade member 7 which are to be inserted between and if inward protrusion P ₁ adjacent the workpiece W _1. Each blade 7 is to be inserted between and if inward protrusion P ₁ in the work W _1, it does not damage the ends of the workpiece W _1. Each blade 7 is shown in FIG.
As shown in ( ₁₎ , between the inwardly protruding portions P ₁ , it is temporarily stopped at an intermediate position immediately above the ring groove 1. FIG.
As shown in (1), a burr B is formed on one side surface 1a of the ring groove 1. A space V is provided between each blade body 7 and both connecting portions P ₁ "facing each other.
Are formed. That is, the blade head H is moved to the workpiece W _1.
Are arranged at a non-pressurized position with respect to. The distance between the side surface 7b of the blade body 7 and the side surface 1a where the burr B is formed in each space portion V is defined as e ₁ and e ₂ , respectively. In this state, the pressurizing unit U ₁ is operated and the direction to approach the side surface 1a of burrs B occurs the blade head H of each inward protrusion P ₁ direction (the positioned workpiece W ₁ of the arrow R ). As a result, as shown in FIG. 8, each blade 7 is pressurized to the side surface 1a of one side of the inward protrusion P _1.

[0017] Here, if a variation occurs in the formation position of the inward protrusion P ₁ of the workpiece W ₁ (or the outward protrusion P ₁ '), i.e., the inward protrusion P ₁ and the workpiece W ₁ Axis C of
Angle theta ₁ which bets forms, (in the example shown in FIG. _{8, θ 1 <θ 2)} θ 2 are different if there is. In this case, towards the interval e ₁ it is wider than the distance e _2. As a result, the blade unit head H is moved by the pressing unit U ₁ around the axis C of the workpiece W ₁ as indicated by the arrow R.
In a state where the direction is fixed by an angle rotation, pressure between the side surface 1a of the blade 7 and the inward protrusion P ₁ is different. That is, as shown in FIG. 8, than pressure T ₁ of the blade 7 of the right and left in the drawing view, the larger pressure T ₂ of the blade between them (specific blade 7 '). Therefore, the specific blade body 7 'is more strongly pressed to the side surface 1a. The blade body 7 'in this state is shown by a chain line. However, each blade body 7 constituting the groove deburring apparatus of the present embodiment is attached to the blade body head H via a floating means. That is, each blade body 7 is mounted so as to be finely movable around the fulcrum pin 15 of each blade body support member 14 to which they are mounted. Therefore, the specific blade body 7 'in FIG.
By fine movement along the arrangement direction, it is substantially the same the pressure T ₂ is the pressure T ₁ of the upper and lower blade 7. That is, all the blades 7 including the specific blade 7 'are arranged at the pressing position. As a result, all the blades 7 are almost uniformly pressed against the side surface 1a where the burr B is formed.

In this state, the pneumatic cylinder 6 is operated again, and as shown in FIG. 10, the blade body head H stopped at the intermediate position is lowered. Blade 7, by being slid in a pressurized state to the side surface 1a of the inward protrusion on one side of P _1, burr B is removed resulting in the partial. This operation, since simultaneously performed in all the inward protrusion P ₁ in the work W _1, all the burrs B are removed at a time.

[0019] In this way, when the burr B workpiece W ₁ is removed, the blade head H is stopped at the lowered end position. In this state, the pressurizing unit U ₁ is operated, all of the blade 7 is rotated in the direction opposite to the arrow R (see FIG. 7), the blade head H is non-pressurized position (the inward protrusion P ₁ is disposed if during and). At the same time, each blade body 7 is arranged at the neutral position. The pneumatic cylinder 6 is operated, and the blade body head H is raised to the raised end position. Subsequently, after the work fixing unit U ₃ is operated to release the fixation of the work W ₁ ,
Activating the work positioning unit U ₂ and engaging the pin 10
Evacuation. The work W _{1 from} which the burr B has been removed is discharged, and a new work W ₁ is set on the work mounting seat 12. Through the same steps as above, the work W
_One burr B is removed.

In this embodiment, as shown in FIG.
Inwardly and the protruding portions P ₁ of the outer, P ₁ 'has been described with respect to the workpiece W ₁ provided along the radial direction at its end. However, as shown in FIG. 12 and the claw clutch shaped workpiece W ₂ shown in FIG. 13, a number of projections P ₂ which is provided along its axis C, your predetermined spacing in the circumferential direction In the case where the burrs are provided, the burrs B are removed by the same operation as described above.

[0021] In this embodiment, the workpiece W ₁ which is fixed in a state of being positioned, although a configuration in which the blade head H is raised and lowered, the workpiece W ₁ relative to the fixed blade body head H It may be configured to approach / separate. Similarly, it may be any of the blade head H and the workpiece W ₁ is rotated.

Each of the blade bodies 7 in this embodiment is mounted on the blade head H via floating means so as to be finely movable along the direction in which the blade bodies 7 are arranged.
For each fulcrum pin disposed along a direction perpendicular to the axis C of the workpiece W _1, it may be a finely movable mounted configuration.

In this embodiment, the case where the burrs B of the workpieces W ₁ and W ₂ in which the ring grooves 1 are provided on the inner peripheral surfaces of the many projecting portions has been described. However, it is also possible to remove burrs of a work having a ring groove provided on the outer peripheral surface of a number of protrusions by a groove deburring device having almost the same configuration. Further, when the interference portion exists inside the work, it is possible to remove the burr by configuring the blade body outside the work with reference to the work. When the processing accuracy of a large number of projecting portions of the workpiece is high, even if a large number of blades are fixed to the blade body head (that is, even if they are not mounted via floating means), deburring is possible. is there.

[0024]

According to the groove deburring apparatus of the present invention, a large number of radially or axially projecting portions of a cylindrical work whose both side surfaces are substantially parallel to the axial direction are formed in the circumferential direction. In a work provided at a predetermined interval along, a burr generated on one side surface of the protruding portion by providing a groove on either the inner or outer peripheral surface of the protruding portion, The burr is removed by moving the pressurized blade body relatively to the work. Therefore, burrs generated on one side surface of a number of protrusions in the work can be automatically and simultaneously removed, and
After the blade body attached to the blade body head is inserted between adjacent protrusions of the work, the blade body head and the work are relatively rotated to damage the end of the work. I will not let you. As a result, the work efficiency in the deburring work is improved. When each blade body is attached to the blade body head via floating means, even if there are variations in processing at the formation positions of a number of projecting portions of the work, all blade bodies are pressed almost evenly. Therefore, it is possible to deburr the work described above.
