[0023] Please refer to Figure 2-Figure 4 , Figure 2 is a three-dimensional diagram of the bolt fixture in this embodiment, Figure 3 is a cross-sectional view of the bolt fixture in this embodiment, Figure 4 It is an enlarged view of part A in this embodiment. This embodiment provides a bolt jig, which includes a jig body 1, and the jig body 1 is provided with a plurality of mounting portions 11. Along the height direction of the jig body 1, each mounting portion 11 extends downward from the upper surface of the jig body 1, and each mounting portion 11 is connected to a bolt 10. The plurality of mounting portions 11 are arranged at equal intervals, so that the jig can be installed with a plurality of bolts 10. The axis of each mounting portion 11 is perpendicular to the bottom surface of the jig body 1, and the groove wall of the mounting portion 11 is provided with a locking thread 110 matching the bolt 10, and the bolt 10 is fixed in the jig body 1 by a threaded connection. Compared with the conventional clamping method of the chuck 100, this solution avoids the problem of direct contact between the bolt 10 and the clamp of the chuck 100, and the thread of the bolt 10 itself is connected with the locking thread, which effectively reduces the scratches and indentations on the surface of the bolt 10 and improves the yield rate of the bolt 10.

[0024] Please refer to Figure 5 , Figure 5 In this embodiment, the fixture body 1 is provided with a total of sixty-two mounting portions 11, which are arranged in an array, so that the fixture body 1 can clamp sixty-two bolts 10 at a time, effectively improving the production efficiency of the bolts 10.

[0025] When in use, the bolt fixture is placed horizontally on the workbench, and multiple bolts 10 are connected to multiple mounting parts 11 respectively, and each mounting part 11 is connected to a bolt 10. When connected, one end of the bolt 10 extends into the mounting part 11, and the other end is exposed outside the mounting part 11, and then the bolt 10 is screwed to connect the bolt 10 with the locking thread 110 in the mounting part 11, so that the bolt 10 is fixedly connected to the mounting part 11, and the axis of the bolt 10 is kept perpendicular to the horizontal plane to avoid the bolt 10 tilting during drilling, resulting in the drill hole and the bolt 10 not being coaxial. During the drilling operation, the drill bit of the drilling equipment is kept perpendicular to the horizontal plane, and then the multiple bolts 10 are drilled one by one by the drilling equipment.

[0026] In addition, when connecting multiple bolts 10 to the mounting portion 11, the bolts 10 can be connected to the locking threads 110 in the mounting portion 11 by using a torque wrench. By setting the torque of the torque wrench and connecting the bolts 10 to the locking threads 110 in the mounting portion 11 using the torque wrench, the torque force of the multiple bolts 10 and the mounting portion 11 is the same. In this way, the locking force of the multiple bolts 10 and the fixture body 1 is kept consistent.

[0027] Please refer to Figure 3 Furthermore, the mounting portion 11 includes a guide hole 111 and a connecting hole 112, the guide hole 111 and the connecting hole 112 are connected, one end of the guide hole 111 away from the connecting hole 112 extends to the upper surface of the fixture body 1 along a direction perpendicular to the bottom surface of the fixture body 1, and the guide hole 111 is coaxially arranged with the connecting hole 112, and the locking thread 110 is arranged on the peripheral wall of the connecting hole 112.

[0028] The guide hole 111 is used to guide the bolt 10 to extend into the mounting portion 11 . When the bolt 10 is connected to the mounting portion 11 , the bolt 10 extends into the guide hole 111 and is connected to the locking thread 110 of the connecting hole 112 .

[0029] Furthermore, the diameter of the guide hole 111 is greater than the diameter of the connecting hole 112 , so that the bolt 10 can pass through the guide hole 111 and the interference between the guide hole 111 and the bolt 10 can be avoided.

[0030] Please refer to Figure 6 , Figure 6 It is a three-dimensional diagram of the jig body. In addition, the jig body 1 is also provided with a plurality of chip removal holes 12, and each chip removal hole 12 extends upward from the lower surface of the jig body 1 along the height direction of the jig body 1. Each chip removal hole 12 corresponds to a mounting portion 11, and the chip removal hole 12 and the corresponding mounting portion 11 are coaxially arranged, and each chip removal hole 12 is connected to the corresponding mounting portion 11. By providing the chip removal hole 12, after the bolt 10 completes the punching operation, the debris generated by the punching operation can be discharged from the jig body 1 through the chip removal hole 12.

[0031] Furthermore, the bolt 10 jig also includes an electromagnetic chuck 2. The electromagnetic chuck 2 is a prior art and will not be described in detail here. The electromagnetic chuck 2 is used to fix the jig body 1. When in use, the electromagnetic chuck 2 is placed horizontally on the workbench, the jig body 1 is placed on the electromagnetic chuck 2, and then the electromagnetic chuck 2 is energized. The internal coil of the electromagnetic chuck 2 generates magnetic force after being energized, and the jig body 1 is tightly adsorbed on the surface of the electromagnetic chuck 2, so that the jig body 1 remains fixed. When not in use, the electromagnetic chuck 2 is powered off, so that the jig body 1 can be removed from the electromagnetic chuck 2.

[0032] In addition, in order to ensure accurate alignment and installation of the fixture body 1 , a reference surface 14 is formed on one side of the fixture body 1 , and the reference surface 14 and the bottom surface of the fixture body 1 are perpendicular to each other.

[0033] The fixture body 1 is also provided with a reference hole 13, the axis of which is parallel to the axis of each mounting portion 11. The reference hole 13 is used for the mounting portion 11 to find a reference and ensure the position accuracy of the mounting portion 11.

[0034] In summary, by providing a plurality of mounting portions 11 on the fixture body 1, each mounting portion 11 is connected to a corresponding bolt 10, so that the fixture can carry multiple bolts 10 at a time, greatly improving the working efficiency. The axis of each mounting portion 11 is perpendicular to the bottom surface of the fixture body 1, and the bolt 10 is connected in the mounting portion 11, so that the axis of the bolt 10 always remains perpendicular to the bottom surface of the fixture. A locking thread 110 is provided in the mounting portion 11, and the bolt 10 is fixed in the mounting portion 11 by the locking thread 110. Compared with the clamping method using the chuck 100, this solution avoids the problem of direct contact between the bolt 10 and the clamping of the chuck 100. The thread of the bolt 10 itself is connected to the locking thread, which effectively reduces the scratches and indentations on the surface of the bolt 10 and improves the yield rate of the bolt 10.

[0035] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
