For the purpose of illustrating the objects, technical solutions and advantages of the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

As shown in fig. 1, a finished part is obtained by forming a plurality of through holes or threaded holes with different diameters at preset positions on the square frame edge of a square workpiece.

As shown in fig. 2, a positioning tool auxiliary tool includes: the device comprises a panel 1, a stud 2, a workpiece 3 and a pressing block 4;

the panel 1 is of a plate-shaped structure, a central cross-shaped scribed line is scribed at the center of the panel, a workpiece is scribed with a central line according to a part drawing, and then the central line of the panel is superposed with the central line of a processed part through manual adjustment; the upper surface, the lower surface, the front surface and the rear surface of the panel are positioning reference surfaces; the panel is provided with 8 phi 20 holes, the central position line of the panel is consistent with the central position line of 8 phi 16 holes to be processed of a workpiece, and a through hole is formed by programming according to the position size requirement of the hole on the drawing through a numerical control milling machine, and the panel has the main functions of facilitating tool setting, removing chips and preventing a tool from accidentally damaging a workbench; the panel is provided with 16M 20 threaded holes, the workpiece 3 is limited on the panel through 16 stud locks, different vertical and horizontal movement is realized, the studs are matched with the workbench, and the panel is positioned on the workbench. The tool can ensure the clamping and positioning precision of workpieces for batch of parts without alignment.

The stud 2 is provided with 16 pieces and is of a columnar thread structure, and the positioning of the workpiece 3 in the XY direction is realized through the close fit of the panel 1, the stud 2 and the workbench and the workpiece 3; the function is convenient to position and prevent the workpiece from moving;

the pressing blocks 3 are 4 pieces (the number of the pressing blocks can be adjusted according to needs), as shown in figure 3, the pressing blocks are of plate-shaped structures, and a central hole is formed in the middle of the pressing blocks; the central hole is matched with the stud to compress the workpiece, so that the Z-direction positioning of the workpiece is realized.

The connection relation of the parts is as follows:

the stud 2 is matched with the workbench, the panel 1 is fixed on the workbench, and the workpiece 3 is arranged in the limiting space of the stud 2, so that the workpiece 3 is positioned in the XY direction; the pressing block is matched with the stud to tightly attach the workpiece 3, so that the workpiece is fixed in the 3Z direction.

Furthermore, for better limiting the workpiece 3, a groove matched with the workpiece 3 in shape is formed in the panel 1 corresponding to the installation position of the workpiece 3, so that the workpiece 3 can be clamped in the groove in the panel.

Through the positioning tool, because the panel is square structure, on the one hand can be very convenient fix on the workstation, on the other hand, regard it as the position reference surface, be convenient for calculate the hole site position that needs processing, after once calculating, just can realize repeated batch processing through simple getting of work piece, need not the staff at every turn the clamping work piece and all need marking off once more and calculate the position of punching, and the work piece maintenance is stable, can not be in the phenomenon of the in-process shake that appears, greatly reduced staff's intensity of labour, machining efficiency and processingquality have been improved, waste product loss and product cost have been reduced.
