Description of the Related Art Conventionally, when a reference surface or a reference hole, which is a processing reference, is generally formed on a cast work, one of two positioning casting holes provided in advance in the work is provided in the axial direction of the reference positioning pin device. A reference positioning pin that moves only is fitted in the other casting hole, and the other casting hole has a positioning pin device for absorbing a pitch error, which is a line segment direction connecting the axial direction and the center of the two casting holes (hereinafter, pitch direction). ), A movable positioning pin is fitted, and the pitch error between the two casting holes is absorbed by the movement of the latter positioning pin in the pitch direction.
Further, the draft of the casting hole and the variation of the hole diameter are absorbed by the axial movement of the corresponding positioning pin in each casting hole to position the work. In the latter positioning pin device, a slider shaft 5 is movably supported by a linear bush 4 in a pitch direction on a support case 3 integrally fixed to a jig base 1 as shown in FIG.
The positioning pin 7 is movably inserted in the axial direction orthogonal to the pitch direction to the support sleeve 6 integrally fixed to the support sleeve 6, and is biased by the spring 8 toward the head portion 7a of the positioning pin 7. The head portion 7a was fitted into one of the casting holes H. Further, in this positioning pin device, a dustproof seal is attached to the moving slider shaft 5, the positioning pin 7, and the support sleeve 6 to prevent chips, coolant, and the like from entering.

Therefore, in order to absorb these errors, the positioning pin device described above is used. Then, a device for moving the casting pin of the positioning pin 7 in the pitch direction and in the axial direction is separately housed in the support case and the hollow sleeve 6. Therefore, there is a first problem that the entire apparatus becomes large and the mounting space for the jig base 1 becomes large.
Further, the seal of this device is exposed to the outside, and there is a second problem that is insufficient to prevent the intrusion of foreign matter such as chips and coolant. A first object of the present invention is to obtain a positioning pin device which is compact and has a small mounting area. A second object of the invention is to obtain a positioning pin device having a cover structure having a small number of sealing portions and good dustproofness.

The rocking support pin 16 is inserted into the long hole 15a of
The locating pin 15 is movably supported in the pitch direction and movable in the axis CL1 direction with the oscillating support pin 16 as a reference. In addition, a spring 17 is built in between the swing support pin 16 and the positioning pin 15,
5 is biased toward the head 14 by a spring force. The pin body 15A of the positioning pin 15 and the head portion 14 are integrated by screwing the screw portion at the lower end of the head portion 14 into the pin body 15A. The head portion 14 is formed in a tapered shape with a small diameter portion d2 at the upper end and a large diameter portion d3 at the lower end with reference to a reference portion d1 that is equal to the diameter D1 of the casting hole H1.
Even if there is a hole diameter error of 1 and a draft, the small diameter portion d2 is inserted into the casting hole H1 and the positioning pin 15 descends,
An appropriate diameter portion of the head 14 is fitted into the diameter D1 of the casting hole H1 to position the work W on the jig base 1.

うにしてある。The positioning pin 15 has a support case 12 attached thereto.
A dustproof cover 18 for covering the support case 12 is integrally provided by screwing the head portion 14 toward the support case 12 from the lower end of the head portion 14 protruding outward from the upper end. The dust-proof cover 18 has a skirt 18a facing downwards in the support case 12.
The outer periphery of the upper end of the support case 12 is surrounded while covering the upper part so that a small gap is formed between the outer periphery and the outer periphery of the support case 12 to prevent chips and coolant from entering. Further, the inner space of the dustproof cover 18 communicating with this gap provides a space between the upper end of the support case 12 and the support case 12 so that the dust cover 18 can move toward the support case 12.

することになる。Next, the reference positioning pin device 11 is used in combination with the positioning pin device 10. The difference from the positioning pin device 10 is that the positioning pin 15 moves in the direction of its axis CL1. By itself, there is no swing in the pitch direction, and the other support case 12A corresponding to the support case 12 of the positioning pin device 10 is not provided with the gap ε formed in the pitch direction.
The point is that the hollow hole of 2A is circular. Therefore, the positioning pin device 11 only absorbs the error of the draft of the casting hole H2 and the hole diameter, and the positioning pin 15 of the positioning pin device 10 swings in the pitch direction with respect to the positioning pin device 11. This absorbs the pitch error.

When the workpiece W is placed on the jig base 1 for processing the reference surface A or the like, the positioning pin 15 of the positioning pin device 11 is lowered by engaging with the casting hole H2, and the head portion is moved. An appropriate diameter portion of the tapered surface of 14 is fitted into the casting hole H2 to absorb the draft of the casting hole H2 and the variation in hole diameter. On the other hand, the head 1 of the positioning pin 15 of the positioning pin device 10
No. 4 engages with the casting hole H1 when the workpiece W is placed on the processing table 2 on the jig base 1, and the positioning pin 15 moves in the direction of the axis CL1 against the spring force of the spring 17. By moving in the pitch direction, variations in hole diameter and pitch error are absorbed, and the diameter D1 of the casting hole H1 and an appropriate diameter portion of the taper portion of the head portion 14 match each other so that the casting hole H1 is completely removed. Be inserted. Thus, the work W is the jig base 1
It is placed and positioned on top.
