[Industrial Application Field] The present invention relates to a processing jig used for polishing both end faces of a cylindrical glass rod (hereinafter referred to as rod). [Prior Art] Various machining jigs of this type have been proposed in the past, and one example is a jig for simultaneous machining of multiple pieces disclosed in Japanese Patent Publication No. 54545/1983. As shown in FIG. 3, in order to process a large number of rods 1 at the same time, a top plate 2 and a bottom plate 3 are connected to each other by a cylindrical or cylindrical connecting member 4. A plurality of adhesive grooves 5 and 6 are formed at equal intervals in the circumferential direction on the outer circumferential surfaces of rods 2 and 3, respectively, and each end of the rod 1 is fitted into these adhesive grooves 5 and 6 and fixed with adhesive. This is what I did. As an adhesive, it has a certain adhesive strength,
A material that is easy to adhere and remove is required, and thermoplastic adhesives such as paraffin wax are usually used. Reference numerals 8 and 9 denote dummy glasses that are adhesively fixed between adjacent adhesive grooves on the upper surface of the top plate 2 and the lower surface of the bottom plate 3, respectively, and these dummy glasses 8 and 9 increase the apparent polishing area. to improve the stability and flatness of the processing jig 10,
Also, the edges of the rod end surfaces 11a and 11b may sag, chip, or
It is installed to prevent the occurrence of scratches, etc.
The degree of wear is set to be the same as or lower than that of the rod 1. And dummy glass 8,9
is bonded and fixed with a thermoplastic adhesive having a high softening point, which is different from the adhesive used to bond the rod 1. This is to prevent the adhesive on the dummy glasses 8, 9 from melting and the glasses 8, 9 coming off when the top plate 2 and bottom plate 3 are heated when the rod 1 is bonded. To explain the case where the rod 1 is polished using the processing jig 10 having such a configuration, the processing jig 10 is attached to an arm that can reciprocate on the polishing surface plate of a polishing machine, and the jig 10 is Polishing sand such as alumina oxide is applied to the surface using a cast iron surface plate, and then polishing is carried out while constantly supplying an appropriate amount of abrasive such as cerium oxide using a pitch surface plate. As soon as polishing of one side of the rod 1, for example, the end surface 11b on the bottom plate 3 side, is completed, the processing jig 10 is reversed and the end surface 11a of the rod 1 on the top plate 2 side is polished. To adjust the parallelism at this time, an autocollimator is used and observation is performed in a usual manner, and sand polishing is performed by applying an uneven load to the processing jig 10 so that both end surfaces are parallel. Note that the processing jig 10 is mainly used for processing rods whose both end faces are inclined at a certain angle with respect to the circumferential surface of the rod 1, so the diameters of the top plate 2 and bottom plate 3 are changed, and each bonding groove 5 is , 6 are tilted at the same angle. [Problems to be solved by the invention] However, in the conventional processing jig 10, since the rod 1 is fixed to the adhesive grooves 5 and 6 with an adhesive, the jig itself must be placed in a temperature-controlled oven. As a result, the installation and removal of the rod 1 is troublesome and time-consuming, and in addition, if excess adhesive adheres to an area, it must be removed. The drawback was that it was a hassle. Therefore, the present invention has been made to solve the above-mentioned problems, and is intended to provide a processing jig that can securely fix the rod without using adhesive. [Means for Solving the Problems] In order to achieve the above object, the present invention provides a rod holding plate in which a pressing plate storage hole is formed and a V-shaped rod holding groove is formed in the plate thickness direction. ,
A rod holding hole is formed in the center of the upper surface of the rod holding plate, and the rod is arranged in correspondence with the rod holding groove, and the rod is pressed against both side walls of the groove and is stored in the pressing plate storage hole. a pressing plate, a moving means for moving the pressing plate toward and away from the rod holding groove, and a dummy glass fixed to the peripheral edge of the bottom surface on the polishing side of the rod holding plate so as to surround the rod holding groove. It is composed of [Function] In the present invention, the rod is held and fixed by the V-shaped rod holding groove of the rod holding plate and the pressing plate. [Example] Hereinafter, the present invention will be described in detail based on an example shown in the drawings. FIG. 1 is a perspective view showing an embodiment of a processing jig according to the present invention, and FIG. 2 is a bottom view of the same jig. In these figures, this embodiment shows one end surface 11 of two rods 1A and 1B each formed in a cylindrical shape.
An example is shown in which a and 12a are polished at the same time. The processing jig 20 is made of aluminum or the like in a rectangular shape, for example, with a length of 100 mm, a width of 100 mm, and a plate thickness.
A rod holding plate 21 having a size of 10 mm is provided, and a substantially hemispherical fitting hole 23 is formed in the center of the upper surface of this plate 21, into which the lower end of the knife 22 of the Oscar type polisher is fitted. is,
Further, on both sides of this hole 23, two press plate storage holes 24 and 25 are formed which penetrate the front and back surfaces of the plate 21. These press plate storage holes 24, 25
are each made of a rectangular hole, and each of the rods 1A,
Pressing plates 26 and 27 for pressing and fixing 1B are housed, and inner wall surfaces 24a facing back to back with the fitting holes 23 of the holes 24 and 25 sandwiched therebetween;
V-shaped rod holding grooves 28 and 29 are formed in the center of 25a by electric discharge machining or the like, corresponding to the plates 26 and 27, respectively. Each pressing plate 26,
27 are screws 32 and 33 as moving means, respectively.
Accordingly, a pair of guide bars 30a and 30b, 3
1a and 31b, each of the rod holding grooves 28,
It is configured to be moved in a direction toward and away from 29. The respective screws 32 and 33 are screwed into screw holes (not shown) provided on the mutually opposing side surfaces 21a and 21b of the rod holding plate 21 and communicating with the respective press plate storage holes 24 and 25, and their tips As shown in FIG. 2, spherical portions provided in the press plates 26 and 27 are rotatably connected to the center portions of the pressing plates 26 and 27, respectively. Each of the rod holding grooves 28 and 29 has a substantially equilateral triangular shape in plan view, and is formed with precision in the thickness direction of the rod holding plate 21 at an angle of 90°±2' or less with respect to the bottom surface of the plate 21. . Each of the above rods 1
The lower end portions of A and 1B are the respective rod holding grooves 28 and 2.
9 from above, and is fixed in the holding grooves 28, 29 by being pressed by the respective pressing plates 26, 27. In this case, if the length of one side of the rod holding grooves 28 and 29 is to fix the rods 1A and 1B with a diameter of 6 mm, the length of one side of the rod holding grooves 28 and 29 should be √3 times the length, that is, the length of 6×√3 mm. If there is, press plate 2
6 and 27 as well as the lower end peripheral surface 3 of the rods 1A and 1B.
Points can be held at equal intervals shifted by 120 degrees. In reality, it is necessary to provide an appropriate distance between the press plates 26 and 27, so each side has the above dimensions of 6 x √3 mm.
It is an equilateral triangular rod holding groove that is about 1 mm shorter than the rod holding groove. Also, on both side walls of each rod holding groove 28, 29 and on the rod pressing surface of each pressing plate 26, 27, a 0.2 mm
A tape (not shown) made of tetrafluoroethylene or the like having a certain thickness is attached to prevent damage to the rods 1A, 1B due to direct contact between the rods 1A, 1B and the processing jig 20. are doing.
Each of the pressing plates 26 and 27 is connected to the rod 1A,
When 1B is pressed and fixed, it is pressed by a pair of left and right setscrews 35a and 35b, 36a and 36b, which are fixing means, and is fixed at that position, that is, the rod pressing position. A plurality of pins 37 are implanted in the upper peripheral edge of the rod holding plate 21, and button weights 38 for unbalanced loads are fitted onto these pins 37 as necessary. On the other hand, the rod holding plate 2
1 and the respective rod holding grooves 28, 29.
A dummy glass 40 is adhesively fixed to the peripheral edge of the frame. The dummy glass 40 has a plate thickness of, for example, 5 mm,
The glass is polished parallel to the upper surface of the rod holding plate 21, and the lower surface of the glass and the lower end surfaces 11a and 12a of each of the rods 1A and 1B are substantially on the same plane. Of course, the rod holding plate 21 itself is also finished to have highly accurate parallelism (2μ or less) and flatness (2μ or less). In the processing jig 20 having such a configuration, when installing the rods 1A and 1B, first set the processing jig 20 on a flat plate such as a stone surface plate, and chamfer the end faces 11a, 11b, 12a, and 12b, respectively. Place the rods 1A and 1B into the rod holding groove 2.
8, 29 from above and its lower end surface 11a,
12a is brought into contact with the flat plate, and then the screw 3
By tightening the rods 2 and 33 and moving the pressing plates 26 and 27 forward, the rods 1A and 1B are pressed and fixed in the rod holding grooves 28 and 29 with a pressing force of approximately 3 kg. After this, set screws 35a, 35b, 3
6a and 36b fix the pressing plates 26 and 27 at the rod pressing position to prevent the pressing plates 26 and 27 from wobbling due to loosening of the screws 32 and 33 during processing. In particular, when using an Oscar-type polisher, forces are applied from multiple directions within the contact surface to the end surfaces 11a, 12a of the rods 1A, 1B, which are the workpieces. This can prevent wobbling. In this state, each rod 1A, 1B is set perpendicularly to the rod holding plate 21, and its lower end surface 11
a and 12a form the same plane as the lower surface of the dummy glass 40. At this time, the lower end circumferential surface of each rod 1A, 1B has three locations shifted by 120° in the circumferential direction, which are connected to each of the pressing plates 26, 27 and each rod holding groove 2.
It is held in line contact with two inclined side walls 8 and 29, respectively. Since the end surfaces 11a and 12a to be actually polished are separated from this holding portion by the thickness of the dummy glass 40, the pressing plate 26,
The strain stress caused by 27 does not affect the end surfaces 11a and 12a. Next, I will explain the sand polishing of Rods 1A and 1B. This sand polishing is divided into two steps. The first step involves using a sanding machine, which is a commonly used cast iron surface plate, and a silicon carbide grinder. Using sand, a processing jig 20 is mounted on a surface plate so as to rotate, and sand is applied to each side of the rods 1A and 1B. That is, as shown in FIG.
B is attached to the processing jig 20, and the rod 2 is inserted into the fitting hole 23 of the rod holding plate 21.
2 are fitted together, the plate 21 is rotated about this as the center of rotation, and the lower end surfaces 11a and 12a of each rod 1A and 1B are sanded and polished first. Here, if the back surface of the rod holding plate 21 and the bottom surface of the dummy glass 40, that is, the polished surface, are sanded in parallel, the end surfaces 11 of the rods 1A and 1B
a, 11b, 12a, 12b are for the cylinder side
An angle of 90° is guaranteed. That is, if the thickness error between the polished surfaces of the rods 1A and 1B and the dummy glass 40 and the upper surface of the rod holding plate 21 is eliminated, the angle of 90° is guaranteed. By the way, in the first step mentioned above, we achieved an accuracy of less than 90°±2' with a plate thickness error of less than 2μ. In the second process, the amount that had to be removed in the second process was removed while maintaining this plate thickness error of 2μ. The purpose of sanding in this second step is to adjust the length of the rods 1A, 1B and to smoothen the sanding surface as a pre-polishing step. When the polishing of the end surfaces 11a, 12a is completed in this manner, the rods 1A, 1B are reversed and the opposite end surfaces 11b, 12b are polished with sand.
However, the processing of the end faces 11b and 12b is done using rod 1A,
Perform 1B one by one. This is rod 1A, 1B
When trying to obtain a highly accurate parallelism of several seconds, use the rods 1A, 1 as in this machining jig 20.
This is because even if the rod holding grooves 28 and 29 for holding and fixing B are machined with high precision, they cannot be formed exactly the same. Also, Rod 1
This is because it is impossible to simultaneously polish the upper end surfaces 11b and 12b of the two rods 1A and 1B to achieve a parallelism of less than a few seconds for both rods, due to the straightness of the cylindrical side surfaces of A and 1B. be. Thus, the processing jig 20 having such a configuration
According to the table below, as is clear from the table below, compared to the conventional jig shown in Fig. 3, both flatness and parallelism are highly accurate and there is no edge droop, both during mounting on the jig and after removal. Rod 1A in good polishing condition,
1B is obtained.
