DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See Figures 1 to 5 A drilling fixture includes a first support plate 100, which is connected to a fixed plate 200 and a rotatable movable plate 300, and the movable plate 300 is located above the fixed plate 200. A jaw for clamping a ring rod 102 is formed between the fixed plate 200 and the movable plate 300, and a U drill 101 is inserted into the jaw to drill a hole in the ring rod 102.

[0024] Two movable plates 300 are provided, and the two movable plates 300 are connected by a rotating shaft 330. One end of the rotating shaft 330 is connected to the first support plate 100, and the other end is connected to the second support plate 400. The fixed plate 200 and the movable plate 300 are located between the first support plate 100 and the second support plate 400. The two movable plates 300 and the fixed plate 200 form two jaws on both sides, so that the two legs of the ring rod 102 can be fixed separately and drilled in the two jaws at the same time.

[0025] Each movable plate 300 is connected to a movable arm 310, and a second power source 320 is installed on the top of the movable arm 310 to drive the movable arm 310 to rotate. The second power source 320 is a cylinder. Through the action of the cylinder, the two movable arms 310 can move away from each other, and the movable plate 300 can move toward the fixed plate 200, so that the jaws can clamp the ring rod 102.

[0026] The first support plate 100 is equipped with two first adjustment plates 110, each of which is provided with a first adjustment slot. The first adjustment plates 110 are fixed to the first support plate 100 by fasteners passing through the first adjustment slot. The first adjustment plates 110 can be moved by being fastened into the first adjustment slot. The two movable arms 310 are connected to a first tension spring 111, the other end of which is connected to the corresponding first adjustment plate 110, so that when the second power source 320 drives the movable arms 310 to move, the two movable arms 310 can move simultaneously, thereby ensuring that the pressure of the two jaws on the ring rod 102 is consistent. At the same time, the first support plate 100 is also equipped with two second adjustment plates 120, each of which is provided with a second adjustment slot. The second adjustment plates 120 are fixed to the first support plate 100 by fasteners passing through the second adjustment slot. The second adjustment plates 120 can be moved by the movement of the fasteners in the second adjustment slot. The fixing plate 200 is connected to a second tension spring 121 , and the other end of the second tension spring 121 is connected to the second adjustment plate 120 , which can further ensure the stability of the pressure of the jaws on the ring rod 102 .

[0027] The second support plate 400 is equipped with the first power source 600, and the first power source 600 is a hydraulic cylinder, which is connected to a hydraulic station. The first power source 600 is connected to a support 610 that extends axially outward along its output shaft, and the support 610 is equipped with a rotatable drive rod 620. The drive rod 620 comprises a first end 621 and a second end 622, and the support 610 is connected between the first end 621 and the second end 622. The first end 621 is rotationally connected with the output shaft of the first power source 600, and the second end 622 is equipped with an adjusting rod 630. The second section stretches into the jaws so that the adjusting rod 630 can resist the ring rod 102, thereby the ring rod 102 is played to the effect of the axial pressure when the U drill 101 is drilled, thereby preventing the ring rod 102 from deflecting and affecting the precision of drilling.

[0028] The second end 622 of the driving rod 620 is provided with a threaded hole, and the adjusting rod 630 is a threaded rod. The adjusting rod 630 is threadedly connected to the threaded hole, and the distance between the adjusting rod 630 and the ring rod 102 can be adjusted by rotating the adjusting rod 630, or the adjusting rod 630 of different lengths can be replaced to adapt to different types of ring rods 102. The pressure output by the second power source 320 is controlled by the hydraulic station, so that appropriate pressure can be applied to different ring rods 102.

[0029] The movable plate 300 and the fixed plate 200 are both equipped with a pad 500. The pad 500 contacts the ring rod 102 to maintain the stability of the ring rod 102. The edges of the movable plate 300 and the fixed plate 200 are provided with a plurality of first limiting protrusions 210. Adjacent first limiting protrusions 210 form a first limiting groove 220 between two adjacent first limiting protrusions 210. The pad 500 is provided with a plurality of second limiting protrusions 510. Adjacent second limiting protrusions 510 form a second limiting groove 520. The pad 500 is provided with a mounting hole 501. The fixed plate 200 and the movable plate 300 are provided with a mounting groove 201. The pad 500 is fixed by a fastener that passes through the mounting hole 501 and extends into the mounting groove 201. When the pad 500 is fixed to the fixed plate 200 or the movable plate 300 , the first limiting protrusion 210 is embedded in the second limiting groove 520 , and the second limiting protrusion 510 is embedded in the first limiting groove 220 , thereby ensuring the stability of the connection.
