It can be understood that the target angle value is one of multiple angle values. The target angle value is determined according to the angle that the workpiece to be processed needs to be fixed on the processing machine table to ensure that the angle between the reference plane 11 and the mounting surface 21 is the target angle. value, the angle of the workpiece to be processed on the processing machine table is the required angle.

For example, the angle θ in FIG. 2 is the angle between the reference surface 11 and the mounting surface 21 .

When the jig provided in this embodiment is used, the base 1 is installed on the processing machine table, the workpiece to be processed is connected to the mounting surface 21 of the movable block 2, and the reference part corresponding to the target angle value is first found on the base 1 13. The indicator part 22 on which the movable block 2 moves is aligned with the reference part 13. Then, the movable block 2 is fixed to the base 1 using a fixing component. At this time, the angle θ between the reference surface 11 and the mounting surface 21 is The target angle value, that is, the angle of the workpiece to be processed on the processing machine table is the required angle, and the workpiece to be processed is stably fixed, ensuring the accuracy of the angle of the workpiece to be processed, and a batch can be processed once fixed The workpiece to be processed does not need to frequently correct the angle.

Alternatively, in other embodiments, the reference part 13 can be a scale line, each scale line corresponds to an angle value, and the indicator part 22 is a straight line or a plane. When the straight line or plane is aligned with the scale line, the reference plane 11 and the installation The angle θ between the surfaces 21 is the angle value corresponding to the scale line.

For example, in this embodiment, one end of the movable block 2 is rotatably connected to the connecting surface 12 through the rotating shaft 5. The indicating part 22 is spaced apart from the rotating shaft 5. The indicating part 22 is the first hole and the reference part 13 is the third hole. When the first hole slot and the second hole slot corresponding to the target angle value are aligned and connected, the angle θ between the reference plane 11 and the mounting surface 21 is the target angle value. With such a structure, it is possible to check whether the first hole slot and the second hole slot are aligned and connected through the insertion of the shaft pin. Compared with the method of observing whether the scale lines are aligned through the human eye, this embodiment can avoid lower accuracy due to human error. Low problems occur.

For example, the fixing component includes an angle positioning pin 31, and the angle positioning pin 31 can be inserted into the first hole slot and the second hole slot that are aligned with each other and communicated with each other. The angle positioning pin 31 not only checks whether the first hole slot and the second hole slot are aligned and connected, but also plays a role in fixing the movable block 2 .

The hole diameter of the reference part 13 matches the diameter of the small diameter section. The small-diameter section of the angle positioning pin 31 is inserted from the opening of one end of the indication part 22 away from the reference part 13 , thereby realizing the fitting and insertion of the angle positioning pin 31 with the indication part 22 and the reference part 13 .

Illustratively, as shown in Figures 3 and 4, in this embodiment, the movable block 2 has an operating surface 27 adjacent to the installation surface 21, and the indicating portion 22 is provided on the operating surface 27. The deviation operation of the movable block 2 The side surface of the surface 27 is rotated to fit on the connecting surface 12 .

For example, the first connection hole 15 is opened on the connection surface 12 of the base 1, the second connection hole 26 is opened on the operating surface 27 of the movable block 2, and the rotation shaft 5 rotates through the first connection hole 15 and the second connection hole 15. Two connecting holes 26 realize the rotational connection between the movable block 2 and the base 1.

Alternatively, in other embodiments, an indication part 22 may be provided on the movable block 2, and the indication part 22 can be aligned with multiple reference parts 13 one by one. In this case, the multiple reference parts 13 surround the first The connecting holes 15 are arranged at intervals in the circumferential direction of the center of the circle.

By way of example, in this embodiment, multiple indicating parts 22 are provided on the movable block 2 , and each reference part 13 can be aligned with one indicating part 22 . When the fixture is fixed, first find the reference part 13 corresponding to the target angle value, and then move the movable block 2 until an indicating part 22 on it is aligned with the reference part 13 corresponding to the target angle value. At this time, the reference plane The angle θ between 11 and the mounting surface 21 is the target angle value. Multiple indicating parts 22 are provided, and each reference part 13 can be aligned with one indicating part 22 , so that the multiple reference parts 13 do not need to be distributed around the circumference of the first connection hole 15 . If the multiple reference parts 13 are arranged around the first connecting hole 15 The connecting holes 15 are distributed circumferentially, and there must be a gap between two adjacent reference parts 13, and the reference part 13 in this embodiment is a second hole slot, causing the movable block 2 to move from one reference part 13 to another adjacent one. The rotation angle of one reference part 13 is large, that is, the difference in angle values corresponding to two adjacent reference parts 13 is large, and the multiple reference parts 13 in this embodiment can be at any position on the connecting surface 12 The distribution, in this way, reduces the angle difference between the angle values corresponding to adjacent reference portions 13, thereby increasing the number of adjustable angles and thereby expanding the applicable scope.

For example, as shown in FIG. 1 , an anti-collision avoidance slope 23 is provided at one end of the movable block 2 away from the rotation axis 5 and away from the mounting surface 21 . Taking the orientation shown in Figure 2 as an example, the arrangement is such that when the movable block 2 rotates, the movable block 2 will not exceed the right side wall of the base 1, thereby preventing the movable block 2 from colliding with the processing machine.

Exemplarily, the fixing assembly includes at least one threaded connector 32, a plurality of fixing holes 24 are opened on the movable block 2, a plurality of threaded holes 14 are opened on the connecting surface 12, and the indicator part 22 is aligned with the target angle value. When referring to the reference portion 13 , at least one of the plurality of fixing holes 24 is aligned and connected with at least one of the plurality of threaded holes 14 , and each set of aligned and connected fixing holes 24 and threaded holes 14 can be threaded with one thread at the same time. Connector 32. The threaded connector 32 is locked to the fixing hole 24 and the threaded hole 14, thereby improving the firmness of the connection between the movable block 2 and the base 1. In this embodiment, the threaded connector 32 is a screw or bolt.

For example, as shown in Figures 1 and 4, the base 1 has a plurality of reference planes 11, which are connected end to end and are surrounded by the connection surface 12. The connection surface 12 corresponds to each The reference surface 11 is provided with a plurality of reference parts 13. The angle values corresponding to the reference parts 13 corresponding to any two reference surfaces 11 are different from each other. When the indicating part 22 is aligned with the reference part 13 corresponding to the target angle value, the reference part 13 corresponds to the target angle value. The angle θ between the reference plane 11 corresponding to the part 13 and the mounting surface 21 is the target angle value. Such an arrangement allows the fixture to have more adjustable angles and expands its scope of application.

Illustratively, in this embodiment, as shown in Figure 1, the base 1 is a cubic structure, and its periphery includes two opposite squares and four rectangles arranged between the two squares, one of which is a connecting square. Surface 12, the four rectangles are all reference surfaces 11. When the jig is installed on the processing machine (the paper surface in Figure 5 is the processing machine table), as shown in Figure 5, one of the four reference surfaces 11 faces the processing On the machine table, the other datum plane 11 faces the front side of the processing machine. The movable block 2 rotates until the indicating part 22 is aligned with the reference part 13 corresponding to the forward datum plane 11, so that the forward datum plane 11 and the installation The angle θ between the surfaces 21 is a target angle value. For example, as shown in Figures 2 and 5, the angle values corresponding to the two reference portions 13 corresponding to the forward reference plane 11 are 12° and 20°, and the two reference portions 13 are arranged upward and movable. When the block 2 rotates until the indicator part 22 is aligned with the reference part 13 corresponding to 12°, the angle θ between the forward reference surface 11 and the mounting surface 21 is 12°.

It should be noted that the fixed orientation of the base 1 of the jig on the processing machine is not fixed. The fixed orientation of the base 1 needs to be determined according to the target angle value. For example, the reference plane 11 corresponding to the target angle value is It is arranged forward, and the reference part 13 corresponding to the target angle value is arranged upward.

For example, the angle values corresponding to all reference portions 13 corresponding to the reference plane 11 are engraved on it. Such an arrangement makes it easy to quickly determine the fixed orientation of the base 1 and improves work efficiency.

For example, the outer edge of each reference portion 13 is engraved with an angle value corresponding thereto. Such an arrangement makes it easy to quickly find the reference portion 13 corresponding to the target angle value, thereby improving work efficiency.

Illustratively, in this embodiment, as shown in Figures 1 and 4, eight reference portions 13 are provided on the connection surface 12, and 12°, 20°, 15°, 22°, 14°, 17°, 10°, 18°. Correspondingly, two indicating parts 22 are provided on the movable block 2.
