As shown in FIGS. 1 and 3 , the row position processing jig 10 in one embodiment of the present invention includes a jig body 12 , and the jig body 12 includes a locking portion 122 and a support portion located on one side of the locking portion 122 124. The supporting part 124 is used as a supporting part of the row position 20 , and the locking part 122 is used for fixing the row position processing jig 10 on the CNC machine tool processing platform 40 , and cooperates with the support part 124 to position the row position 20 .

The support portion 124 has a support surface 1242 as the top surface of the support portion 124, the locking portion 122 has an abutment surface 1222 adjacent to the support surface 1242, the support surface 1242 and the abutment surface 1222 have a preset Angle settings. In the positioning of the row position 20, one side of the row position 20 is against the abutment surface 1222, the bottom is supported by the support part 124, and the support surface 1242 and the abutment surface 1222 are set at a preset angle, so that the row position 20 Predetermined inclined processing can be realized.

The positioning tool 10 also includes a positioning piece 14 and a pressing piece 16. The positioning piece 14 is disposed on the support surface 1242 to cooperate with the support surface 1242 and the abutment surface 1222 to form a fixed position (not shown). The pressing member 16 is disposed on the support surface 1242 for fixing the row position 20 at the fixed position.

Please refer to FIG. 2 and FIG. 3 , in this embodiment, the row position 20 is a cuboid structure, which has a first side 22 along a first direction, and a second side 24 along a second direction, and the second side 24 is adjacent to each other. Connected to the first side 22, specifically, the first direction is perpendicular to the second direction, more specifically, the first direction is the transverse direction as shown in Figure 3, and the second direction is the longitudinal direction as shown in Figure 3 direction.

The row position processing jig 10 includes a positioning state. When the row position processing jig 10 is in the positioning state, that is, when the row position 20 is fixed to the CNC machine tool processing platform 40 by the row position processing jig 10, the row position One side of the position 20 along the first direction is against the abutting surface 1222 , one side of the row position 20 along the second direction is close to the positioning member 14 , and the pressing member 16 is pressed against the top of the row position 20 .

Specifically, in the process of positioning and fixing, the second side 24 of the row position 20 is firstly pressed against the positioning member 14 , and the first side 22 is pressed against the abutting surface 122 to position the row position 20 at the aforementioned fixing position. Then lock the pressing member 16 so that the row position 20 is fixed relative to the row position processing jig 10 , so as to realize the positioning and fixing action of the row position 20 . After the row position 20 is positioned, set the slope gauge on the row position 20, and use the calibration table to correct the plane parallelism and line parallelism of the slope gauge, and then perform centering.

It should be noted that the centering refers to the step of accurately determining the center position of the workpiece to be processed in the machining of the numerical control machine tool. Its working principle is to select one side of the processed workpiece on the X-axis as the zero point, then select the other side to measure the value, and then divide the obtained value by 2, which is the center of the X-axis direction; the measurement principle of the center of the Y-axis direction is the same, In this way, the center of the XY plane of the workpiece is determined.

In this embodiment, the second side 24 of the row position 20 is the X-axis collision surface. Since the row position 20 is skewed, the number obtained from the Y-axis zero position can only touch the sharp corner, that is, the two surfaces meet. At the included angle, as shown in Figure 2, A is the zero position of the Y-axis at row position 20. Then when the row position 20 is fixed at the aforementioned fixed position, the Y-axis zero position of the row position 20 and the junction B between the supporting surface 1242 and the abutting surface 1222 belong to the same position. The horizontal distance between the junction B of the support surface 1242 and the abutment surface 1222 and the side of the support portion 124 away from the locking portion 122 is fixed, therefore, it can be replaced by directly using the side of the support portion 124 away from the locking portion 122 The zero position of the Y-axis at the row position 20 takes the digit, and the measured value can be converted.

In this way, the steps of scoring are simplified, the difficulty of scoring is reduced, and the abnormality caused by the calibration table of scoring is reduced.

It should be understood that the row position 20 is positioned by the support surface 1242, the abutment surface 1222 and the positioning member 14, and is fixed by the pressing member 16. When the row position 20 is processed in batches, only the first workpiece needs to be corrected for parallelism , In the center, when the subsequent workpiece is processed, it can be processed directly after positioning and fixing. And the side of the supporting part 124 away from the locking part 122 is used as the Y-axis zero-position collision surface instead of the Y-axis zero position of the row position 20 to obtain the digital position. Compared with the traditional vise, the positioning is fixed, the steps are simple, the assembly and disassembly are convenient, and it is easy to center, which improves the processing efficiency, ensures the processing quality, and thus improves the utilization rate of the machine.

The supporting surface 1242 is inclined relative to the horizontal plane, and the abutting surface 1222 is set at an angle with the supporting surface 1242. Specifically, in this embodiment, the row position 20 is a cuboid structure, which respectively joins the supporting surface 1242 and the abutting surface 1222. If the surfaces are perpendicular to each other, the abutting surface 1222 and the supporting surface 1242 are also perpendicular to each other, that is, the angle between them is 90 degrees.

It should be understood that the support portion 124 is flush with the bottom plane of the locking portion 122 and parallel to the horizontal plane, and the support surface 1242 and the abutment surface 1222 are perpendicular to each other, then the inclination angle of the support surface 1242 relative to the horizontal plane determines the row position 20 The degree of inclination relative to the horizontal plane.
