[0020] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Example

[0022] A positioning fixture for drilling molds, as shown in the figure, includes a rear fixed plate 1. Positioning drill holes 2 are arrayed inside the rear fixed plate 1. A drive motor 3 is fixedly installed on the upper side of the rear fixed plate 1. A gear 4 is fixedly installed at the output end of the drive motor 3. The gear 4 is located inside the rear fixed plate 1. Two sets of translation plates 5 are installed on both the front and rear sides of the gear 4. A rack 6 is installed on the inner wall of the two sets of translation plates 5 at the position corresponding to the gear 4. A gripper 8 is installed on the left side of one set of translation plates 5 and a gripper 8 is installed on the right side of the other set of translation plates 5. The two sets of grippers 8 are installed opposite each other. A flexible inner plate 9 is fixedly installed on the inner wall of the gripper 8. An installation groove 11 is opened at the front of the rear fixed plate 1. A rotating plate 14 is fixedly installed inside the installation groove 11. A front fixed plate 12 is fixedly installed in front of the rotating plate 14. The front fixed plate 12 has the same structure as the rear fixed plate 1.

[0023] The translation strip 5 forms a translation structure through the rack 6 and the gear 4. The two sets of translation strips 5 move in opposite directions. When in use, the drive motor 3 drives the gear 4 at the bottom to rotate. At the same time, the gear 4 meshes with the rack 6 on the inner wall of the translation strip 5. Therefore, the translation strip 5 is driven by the gear 4 to translate inside the device. During the translation process, the position of the flexible inner plates 9 on both sides inside the device is adjusted to adapt to the width of the position to be drilled, so that the device can be clamped and fixed by the gripping plate 8.

[0024] A translation groove 7 is provided on the side of the translation strip 5 near the inner wall of the rear fixed plate 1. A slider of the corresponding size is provided on the inner wall of the rear fixed plate 1 at the position corresponding to the translation groove 7. During use, when the translation strip 5 is translated left and right, the slider fixedly installed on the inner wall of the rear fixed plate 1 will slide inside the translation groove 7 to prevent the translation strip 5 from shifting during the translation of the device and affecting its use.

[0025] Two sets of positioning bolts 10 are symmetrically arranged at the bottom of the gripper plate 8. During use, the device is fixed to the mold that needs to be drilled by the gripper plate 8, and then the positioning bolts 10 are used to lock the device and the mold together. At the same time, during the fixing process, the flexible inner plate 9 is used to space the mold and the gripper plate 8 to prevent the device from damaging the mold. A rotating shaft 13 is installed through the lower left of the rotating plate 14. A limit groove 15 is opened at the top of the rotating plate 14. A limit slider 16 is fixedly installed on the inner wall of the mounting inner groove 11. The position of the limit slider 16 matches the limit groove 15. During use, the front fixing plate 12 can be rotated inside the mounting inner groove 11 by the rotating shaft 13 through the rotating plate 14 on the back, which facilitates the adjustment of the angle of the front fixing plate 12, improves the flexibility of the device, and facilitates fixing at different drilling positions, which can avoid the need to repeatedly install the device.

[0026] The front fixed plate 12 forms a rotating structure with the rotating plate 14 and the rotating shaft 13. The rear fixed plate 1 forms a translational structure with the rotating plate 14 through the cooperation between the limiting slider 16 and the limiting groove 15. The center of the limiting groove 15 coincides with the center of the rotating shaft 13. During the translation of the rotating plate 14, the limiting slider 16 installed on the inner wall of the mounting inner groove 11 will slide inside the limiting groove 15, which can limit the position of the limiting groove 15, improve the stability of the rotating plate 14, and prevent the rotating plate 14 from falling out of the device.

[0027] Working principle: During use, the device is aligned with the position to be drilled by positioning drill hole 2. Then, drive motor 3 drives gear 4 at the bottom to rotate. At the same time, gear 4 meshes with rack 6 on the inner wall of translation strip 5. Therefore, translation strip 5 is driven by gear 4 to move inside the device. During the translation process, the position of flexible inner plates 9 on both sides inside the device is adjusted to adapt to the width of the position to be drilled, so that the device can be clamped and fixed by gripping plate 8. At the same time, the sliding strip fixedly installed on the inner wall of the rear fixing plate 1 will slide inside the translation groove 7 to prevent the translation strip 5 from shifting during the device translation process and affecting the use. Then, positioning bolts 10 are tightened to fix the device and mold together. During the fixing process, the flexible inner plate 9 is used to space the mold and gripping plate 8 to prevent the device from damaging the mold. Finally, the front fixing plate 12 can be rotated inside the mounting inner groove 11 by rotating shaft 13 through rotating plate 14 on the back, so as to adjust the angle of the front fixing plate 12 and improve the flexibility of the device.
