[0001] The utility model relates to the technical field of positioning structures, in particular to a positioning structure for precision hardware processing. Background Art

[0002] For some hardware processing, a positioning structure is generally provided on it for clamping and fixing the workpiece to be processed. When the workpiece is being processed, the workpiece to be processed can remain in a stable state, making it convenient for the processing mechanism on the machine tool to process the hardware.

[0003] The existing positioning structures for precision hardware processing have several obvious defects: for some hardware processing, the drilling positioning structures are generally fixed on the left and right sides of the workpiece by two clamping heads, and their pressure-bearing capacity is weak. When the positioning structure contacts the outside of the hardware, the force generated may cause a certain degree of bending in the middle of the workpiece, resulting in a certain deviation in the hole diameter. Therefore, improvements are now made to a positioning structure for precision hardware processing. Utility Model Content

[0028] The support assembly includes a sliding frame 12, the internal sliding sleeve of the sliding frame 12 is provided with a support frame 14, the internal threaded sleeve of the support frame 14 is provided with a screw 16, one end of the screw 16 is connected to a motor 15, the bottom of the motor 15 is fixedly connected to the sliding frame 12, and a support plate 13 is installed on the top of the support frame 14, and a slot 18 is opened on the outside of the support plate 13.

[0029] like Figure 4 As shown, the sliding assembly includes a slide rail 11 fixedly mounted on the outside of the mounting frame 2, and the outside of the slide rail 11 is slidably connected to an adjustment frame 10. The adjustment frame 10 is U-shaped, and the internal threaded sleeve of the adjustment frame 10 is provided with a bolt 20. The adjustment frame 10 is fixedly connected to the sliding frame 12, so that the adjustment frame 10 can be adjusted by moving the slider 17 to the left or right along the outside of the slide rail 11 until the adjustment frame 10 moves to the corresponding drilling position of the workpiece, so that the position of the hardware punching can be adjusted.

[0030] like Figure 2 and Figure 3As shown, the fixing assembly includes a mounting plate 1 4 slidably connected to one side of the top of the mounting frame 2, and a mounting plate 2 3 is fixedly connected to the other side of the top of the mounting frame 2. A fixing frame 7 is fixedly installed on the opposite side of the mounting plate 1 4 and the mounting plate 2 3. The internal thread of the fixing frame 7 is provided with a fixing rod 8, so that the mounting plate 1 4 moves to the right along the outside of the guide block 6 through the guide groove 19 at the bottom, so that the two sides of the hardware plate are fitted with the inner side of the fixing frame 7, and then the fixing rod 8 is rotated to move the fixing rod 8 downward, thereby fixing the hardware in the fixing frame 7. The fixing frame 7 has a sideways U-shaped structure, which is convenient for overall installation.

[0031] like Figure 2 and Figure 3 As shown, a connecting frame 5 is installed on the outside of the mounting frame 2, and a cylinder 9 is provided inside the fixing sleeve of the connecting frame 5. The output shaft of the cylinder 9 is fixedly connected to the outside of the mounting plate 4, and the output shaft of the cylinder 9 pushes the mounting plate 4 to move.

[0032] like Figure 4 As shown, a slider 17 is connected to the side of the adjusting frame 10 close to the slide rail 11. The adjusting frame 10 is slidably connected to the slide rail 11 through the slider 17. The adjusting frame 10 is adjusted by moving the slider 17 to the left or right along the outside of the slide rail 11 until the adjusting frame 10 moves to the corresponding drilling position of the workpiece. The slider 17 is a long strip structure, which is convenient for sliding guidance and installation of the adjusting frame 10.

[0033] like Figure 1 and Figure 4 As shown, a threaded hole is provided inside the support frame 14 , and the screw rod 16 is threadedly engaged with the support frame 14 , so that the support frame 14 outside the screw rod 16 can move vertically on the sliding frame 12 .

The guide groove 19 is slidably connected to the guide block 6. The output shaft of the cylinder 9 pushes the mounting plate 4 to move, so that the mounting plate 4 moves to the right along the outside of the guide block 6 through the guide groove 19 at the bottom, so that the two sides of the hardware plate are fitted with the inner side of the fixing frame 7, thereby adapting to the length of different hardware.

[0035] Working principle:

[0036] When in use, first place the two sides of the hardware plate to be punched in the fixing frame 7, and by controlling the cylinder 9 to start, the output shaft of the cylinder 9 can push the mounting plate 4 to move, so that the mounting plate 4 moves to the right along the outside of the guide block 6 through the guide groove 19 at the bottom, so that the two sides of the hardware plate fit into the inner side of the fixing frame 7, and then rotate the fixing rod 8 to move the fixing rod 8 downward, thereby fixing the hardware in the fixing frame 7, and then adjust according to the drilling position of the workpiece, so that the adjusting frame 10 moves to the left or right along the outside of the slide rail 11 through the slider 17 for adjustment, until the adjusting frame 10 moves to the right side in line with the workpiece. The drilling position of the workpiece can correspond to it, so that the position of the hardware drilling can be adjusted, and then the bolt 20 is rotated clockwise so that the end of the bolt 20 contacts the outer side of the slide rail 11, thereby fixing the position of the adjustment frame 10. When adjusting the height, the motor 15 is started by controlling the output shaft of the motor 15 to drive the screw 16 to rotate, so that the support frame 14 outside the screw 16 can move up vertically on the sliding frame 12 until the support plate 13 on the top of the support frame 14 contacts the bottom of the workpiece. After that, the processing mechanism can be started to drill the workpiece to avoid a certain degree of bending caused by the force applied to the hardware plate during drilling.

[0037] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
