[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Please refer to Figures 1-3 A high-efficiency precise drilling jig, comprising a jig body 1, two limiting blocks 2 are oppositely arranged on the top surface of the jig body 1 and located at the side edges of the jig body 1, and a working groove 3 is formed between the two limiting blocks 2. The limiting block 2 is provided with a clamping groove 21 penetrating through the two side walls and the top surface thereof, the opposite two side walls of the clamping groove 21 are provided with vertically extending arc-shaped grooves 22, the two arc-shaped grooves 22 cooperate with the clamping groove 21 to form a drill positioning hole 4 for the drill to pass through, and the drill positioning hole 4 is used for accurately guiding the drill to perform drilling work on the workpiece. The opposite two side walls of the clamping groove 21 are provided with horizontally extending limiting grooves 23, and the two limiting grooves 23 cooperate with the clamping groove 21 to form a workpiece positioning hole 5 for the end part of the workpiece to pass through.

[0026] In the embodiment, the specification of the cross section of the workpiece positioning hole 5 is consistent with the specification of the cross section of the end part of the workpiece, the drill positioning hole 4 vertically penetrates to the top surface of the limiting block 2, the workpiece positioning hole 5 horizontally penetrates to the two side walls of the limiting block 2, the workpiece positioning hole 5 cooperates with the drill positioning hole 4 to form an inverted T-shaped structure, and an external stop block (not shown in the figure) is arranged at the connection between the workpiece positioning hole 5 and the outer wall of the limiting block 2, the external stop block is used for limiting the length of the workpiece and has a positioning effect on the workpiece.

[0027] This invention inserts the two ends of the workpiece into the workpiece positioning holes 5 of the two limiting blocks 2. The workpiece positioning holes 5 limit and position the workpiece, preventing circumferential rotation during drilling. The drill bit positioning hole 4 accurately positions the workpiece drilling area and guides the drill bit to drill in the correct direction. Furthermore, the external stop block further limits and positions the workpiece ends, preventing lateral movement of the workpiece during drilling. This ensures reliable fixation of the workpiece during drilling, thereby improving the drilling accuracy, reducing the workpiece scrap rate, and significantly improving the production efficiency of the workpiece.

[0028] Please see Figure 1 and Figure 3 The limiting groove 23 has a circular arc groove at the bottom and a horizontally extending limiting plane 231 at the connection between the upper part of the limiting groove 23 and the side wall of the clamping groove 21. The limiting planes 231 of the two limiting grooves 23 and the clamping groove 21 form a right-angle keyway structure. The end of the workpiece is positioned by the right-angle keyway structure, thereby preventing the workpiece from rotating circumferentially during the drilling operation, and the positioning effect is better.

[0029] Please see Figure 1 The bottom wall of the working groove 3 is provided with a template fixing bolt hole 6 that extends through to the bottom surface of the fixture body 1.
