[0037] By using the first reference surface 32 as the support surface and the third positioning hole 38 as the fixing hole, the positioning seat 3 is installed on the machine tool, facilitating the machine tool to drill the positioning pin hole 42 in the adjustable optical fiber interface 4. By using the second reference surface 34 as the support surface, the positioning seat 3 is installed on the machine tool, facilitating the machine tool to drill the square inclined hole 43 in the adjustable optical fiber interface 4.

[0038] The axes of the positioning pin hole 42 and the square inclined hole 43 are inclined with respect to each other.

[0040] During the process of drilling the square inclined hole 43, the axis of the square inclined hole 43 is perpendicular to the second reference surface 34.

[0042] The lower part of the adjustable optical fiber interface 4 is placed in the third positioning hole 38, and both sides of the adjustable optical fiber interface 4 are respectively placed in the fixed slots 39 on both sides. The pressing bolt 2 fixes the pressing plate 1 on the top surface of the positioning seat 3, and the two pressing plates 1 respectively press down both sides of the adjustable optical fiber interface 4 into the fixed slots 39 for fixation.

[0043] The adjustable optical fiber interface 4 is pressed down into the positioning seat 3 through the pressing bolt 2 and the pressing plate 1. Among them, both sides of the adjustable optical fiber interface 4 are pressed into the fixed slots 39, and the middle part of the adjustable optical fiber interface 4 is pressed down into the third positioning hole 38, so as to fix the adjustable optical fiber interface 4 from above, below and the circumferential side, improving the stability during the processing.

[0044] The adjustable optical fiber interface 4 to be processed is firmly installed on the positioning seat 3, and the direction of the acting force of the tool is from the adjustable optical fiber interface 4 to the positioning seat 3, so that the adjustable optical fiber interface 4 is stably attached to the positioning seat 3 and the adjustable optical fiber interface 4 will not bulge.

[0045] Refer to Figure 3 , a chip removal groove 35 is opened in the seat body 31, and the chip removal groove 35 penetrates the seat body 31 along the transverse direction.

The second positioning hole 37 corresponds to the positioning pin hole 42, the first positioning hole 36 penetrates the seat body 31 and communicates with the third positioning hole 38, and the first positioning hole 36 and the third positioning hole 38 are coaxially arranged.

[0047] The chip removal groove 35, the first positioning hole 36, the second positioning hole 37, the third positioning hole 38 and the fixed slot 39 form an opening component for opening a hole in the adjustable optical fiber interface 4; a plurality of the opening components are distributed along the length direction of the seat body 31.

[0048] Each of the opening components can fix one adjustable optical fiber interface 4, which is convenient for processing a plurality of adjustable optical fiber interfaces 4 simultaneously to improve the processing efficiency.

[0049] Working principle:

[0050] When it is necessary to drill a positioning pin hole 42 in the adjustable optical fiber interface 4, the positioning seat 3 is installed on the machine tool with the first reference plane 32 as the supporting surface and the third positioning hole 38 as the fixing hole, which facilitates the machine tool to drill the positioning pin hole 42 in the adjustable optical fiber interface 4.

[0051] When it is necessary to drill a square inclined hole 43 in the adjustable optical fiber interface 4, the positioning seat 3 is installed on the machine tool with the second reference plane 34 as the supporting surface, which facilitates the machine tool to drill the square inclined hole 43 in the adjustable optical fiber interface 4.

[0052] By taking the first reference plane 32 as the supporting surface and the third positioning hole 38 as the fixing hole, the positioning seat 3 is installed on the machine tool, which facilitates the machine tool to drill the positioning pin hole 42 in the adjustable optical fiber interface 4. By taking the second reference plane 34 as the supporting surface, the positioning seat 3 is installed on the machine tool, which facilitates the machine tool to drill the square inclined hole 43 in the adjustable optical fiber interface 4.

[0053] By setting two supporting surfaces on a fixture and selecting one supporting surface, it is convenient to drill holes in one direction. By selecting the other supporting surface, it is convenient to drill holes in another direction. Thus, holes can be drilled in different directions on the adjustable optical fiber interface 4 on one fixture without replacing the fixture, and the operation is simple.

[0054] Moreover, the current fixture has high requirements for the degrees of freedom of the machine tool because it cannot adjust the orientation of the adjustable optical fiber interface 4 to be machined on the machine tool, and usually a four-axis machine tool is required. The positioning seat 3 of the present application can adjust the orientation of the adjustable optical fiber interface 4 on the machine tool by selecting the supporting surface, so that it is convenient for the tool of the machine tool to drill holes in different directions in the adjustable optical fiber interface 4, and the requirements for the degrees of freedom of the machine tool are reduced.

[0055] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
