[0023] Embodiments

[0024] Referring to Figures 1-2 As shown in the drawings, the present application discloses a vertical hole processing positioning jig, which comprises a bottom plate 10. Specifically, the bottom plate 10 is further fixed with a strip-shaped plate 106. A plurality of positioning holes are formed in the strip-shaped plate 106. A bolt passes through the positioning hole to vertically fix the bottom plate 10 on a rotating machine table 20, and the rotation of the bottom plate 10 is driven by the rotating machine table 20.

[0025] Referring to Figures 3-4As shown, the bottom plate 10 is provided with a positioning module, a pressing module and a clamping module. The positioning module includes a circular table arranged on the bottom plate 10. Specifically, the circular table includes a large circular table 101 and a small circular table 102. The large circular table 101 is fixed on the bottom plate 10, and the small circular table 102 is fixed on the large circular table 101. The fixed hole 301 in the middle of the workpiece 30 is sleeved into the small circular table 102 and abuts against the end face of the large circular table 101. The small circular table 102 is used to fix the workpiece 30 on the bottom plate 10. The end face of the large circular table 101 serves as a positioning reference, so that the workpiece 30 is in a vertical state, thereby ensuring the drilling accuracy.

[0026] Referring to Figures 3-4 As shown, the pressing module includes a pressing rod 1031 arranged around the circular table. Specifically, the pressing module includes two pressing cylinders 103 arranged symmetrically. One end of the pressing rod 1031 is installed on the piston rod of the pressing cylinder 103, and the other end of the pressing rod 1031 is installed with a pressing block. The pressing cylinder 103 is controlled to retract to drive the pressing rod 1031 to press the workpiece 30 on the large circular table 101, so as to avoid the workpiece 30 from rotating around the small circular table 102 during the rotation of the bottom plate 10, thereby achieving the function of pressing and fixing the workpiece 30.

[0027] Referring to Figures 3-4 As shown, the clamping module includes a push rod 1041 and a positioning block 105. The push rod 1041 is pressed against the positioning block 105. Specifically, the positioning block 105 is in an L shape. A support plate is installed on the bottom plate 10. A clamping cylinder 104 is installed on the support plate. The push rod 1041 is installed on the piston rod of the clamping cylinder 104. The workpiece 30 sleeved on the small circular table 102 is rotated until a protruding part 302 of the workpiece 30 abuts against the positioning block 105. The clamping cylinder 104 is controlled to push the push rod 1041 to press the protruding part 302 against the positioning block 105, thereby achieving the positioning function of the positioning block 105.

[0028] Working process: The fixed hole 301 of the workpiece 30 is sleeved on the small circular table 102 and abuts against the end face of the large circular table 101. The workpiece 30 is rotated until the protruding part 302 of the workpiece 30 abuts against the positioning block 105. The clamping cylinder 104 is controlled to push the push rod 1041 to press the protruding part 302 against the positioning block 105. Finally, the pressing cylinder 103 is controlled to retract to drive the pressing rod 1031 to press the workpiece 30 on the large circular table 101. The bottom plate 10 is installed on the rotary machine table 20. The workpiece 30 is rotated by 90° through the rotation of the rotary machine table 20. Each rotation is sequentially corresponding to the drilling of the protruding part 302 by the drill, thereby completing the machining of the threaded hole 303. The workpiece 30 is quickly fixed, the efficiency is improved, and the dimensional error is reduced.

[0029] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
