The top position of the outer wall of the vertical frame 13 is installed with a first driving component, and the outer walls of the two groups of first driving components are both installed with a second vertical plate 14.

[0032] Start the two sets of telescopic cylinders 6 to extend and drive the connecting block 4 and the two sets of second vertical plates 14 to move so as to increase the distance between them; then place the pressing flange to be processed vertically between the two sets of second vertical plates 14; restart the two sets of telescopic cylinders 6 to contract and drive the two sets of second vertical plates 14 to be squeezed onto the two sides of the pressing flange.

[0033] Please refer to the attached figure in the instruction manual Figure 1 , 2 3. A center of gravity block 19 is fixed at the central position of the outer wall of one side of the two sets of second vertical plates 14, and multiple sets of springs 20 are evenly installed on the outer walls around the two sets of center of gravity blocks 19.

Press the multiple sets of abutment plates 18 to move toward the side of the center of gravity block 19 and drive the multiple sets of springs 20 to contract and produce elastic deformation. Then, the buckling flange is sleeved on the outside of the multiple sets of abutment plates 18, and the abutment plates 18 are loosened and driven to move synchronously outward and tightly engage the buckling flange under the elastic performance of the multiple sets of springs 20. Since the specifications of the multiple sets of springs 20 are the same, the multiple sets of abutment plates 18 move the same distance, so that the center of the buckling flange can be automatically aligned.

A second driving motor 17 is fixed to the inner wall of the third mounting frame 16, and a second rotating shaft 15 fixed to the outer wall of the second vertical plate 14 is installed at the output end of the second driving motor 17. The two sets of second driving motors 17 are started synchronously to drive the second rotating shaft 15 and the second vertical plate 14 to rotate in the same direction, thereby driving the pressing flange to rotate, which is convenient for drilling and chamfering at different angles of the pressing flange.

[0036] Please refer to the attached figure in the instruction manual Figure 1 The outer wall of the first vertical plate 1 is evenly provided with a plurality of positioning holes 2, and the bottom end of the outer wall of the vertical frame 13 is provided with positioning bolts 3 that match the threads of the positioning holes 2. The positioning bolts 3 are screwed to separate them from the positioning holes 2 at the corresponding positions, and then the vertical frame 13 is moved up and down to the appropriate position, and then the positioning bolts 3 are screwed in the opposite direction to be threadedly connected with the positioning holes 2 at the corresponding positions, thereby adjusting the vertical height between the second vertical plate 14 and the first mounting frame 7, so as to be convenient for buckling flanges of different diameters.

[0037] Please refer to the attached figure in the instruction manual Figure 1 The second drive assembly is fixed to the bottom wall of the second mounting base plate 12, and the first mounting base plate 11 is fixed to the bottom wall of the second drive assembly. The second drive assembly includes a second mounting frame 9, which is fixed at the center of the top wall of the first mounting base plate 11. The first drive motor 8 is fixed to the top wall of the inner cavity of the second mounting frame 9, and the first rotating shaft 10 that penetrates the top wall of the second mounting frame 9 and is fixed to the bottom wall of the second mounting base plate 12 is installed at the output end of the first driving motor 8. Starting the first driving motor 8 drives the first rotating shaft 10 to rotate, thereby driving the second mounting base plate 12 to rotate synchronously, so that the angle of the buckling flange can be adjusted.

[0038] Please refer to the attached figure in the instruction manual Figure 1 , multiple groups of abutment wheel frames 5 are evenly fixed on the top wall of the first mounting base plate 11, and the multiple groups of abutment wheel frames 5 are arranged at the outer position of the second mounting frame 9, and the top walls of the abutment wheel frames 5 are in contact with each other at the bottom wall of the second mounting base plate 12. The second mounting base plate 12 can move on the top of the multiple groups of abutment wheel frames 5 during the rotation process, so that the stability of the upper part of the second mounting base plate 12 can be improved under the auxiliary support of the multiple groups of abutment wheel frames 5.

[0039] Working principle: When using the positioning auxiliary tooling for the high-strength press-fit flange drilling and chamfering process, the positioning auxiliary tooling for the high-strength press-fit flange drilling and chamfering process is stably placed on the workbench through the first mounting base plate 11, and the two groups of telescopic cylinders 6 are started to extend to drive the connecting block 4 to move on the top wall of the second mounting base plate 12, thereby driving the two groups of second vertical plates 14 to move back to back to increase the distance between the two. Then, the press-fit flange to be processed is vertically placed in the position between the two groups of second vertical plates 14, and the two groups of telescopic cylinders 6 are restarted to contract to drive the two groups of second vertical plates 14 to be squeezed on both sides of the press-fit flange. The drilling equipment and chamfering equipment in the prior art are used to drill and chamfer the press-fit flange in turn.

[0040] During the process of clamping the pressing flange, the staff first manually presses the multiple groups of abutment plates 18, so that the abutment plates 18 move toward the side of the center of gravity block 19 and drive the multiple groups of springs 20 to contract and produce elastic deformation, and then puts the pressing flange on the outside of the multiple groups of abutment plates 18, loosens the abutment plates 18 and drives the multiple groups of abutment plates 18 to move synchronously outward under the action of the elastic properties of the multiple groups of springs 20 and tightly engage the pressing flange. Since the specifications of the multiple groups of springs 20 are the same, the multiple groups of abutment plates 18 move the same distance and can automatically align with the center of the pressing flange. When moving, the abutment plates 18 can drive the multiple groups of limit blocks 21 to move synchronously in the inner cavity of the limit slide groove 22, thereby limiting the movement path of the abutment plates 18 and preventing their position from shifting.

[0041] When drilling and chamfering are performed, two groups of second drive motors 17 are started synchronously to drive the second rotating shaft 15 and the second vertical plate 14 to rotate in the same direction, thereby driving the pressing flange to rotate, and then the angle of the pressing flange can be adjusted in time when the drilling equipment and the chamfering equipment do not rotate, which is convenient for drilling and chamfering at different angles of the pressing flange. The first drive motor 8 is started to drive the first rotating shaft 10 to rotate, thereby driving the second mounting base plate 12 to rotate synchronously, thereby adjusting the angle of the pressing flange, and facilitating automatic adjustment of the direction of the pressing flange when the drilling equipment and the chamfering equipment do not rotate, so as to facilitate double-sided processing.

[0042] The second mounting base plate 12 can move on the top of the multiple sets of abutment wheel frames 5 during the rotation process, so that the stability of the upper part of the second mounting base plate 12 can be improved under the auxiliary support of the multiple sets of abutment wheel frames 5, and the positioning bolts 3 are screwed to separate them from the positioning holes 2 at the corresponding positions, and then the vertical frame 13 is moved up and down to move it to the appropriate position on the outer wall of the first vertical plate 1, and then the positioning bolts 3 are screwed in the opposite direction to be threadedly connected with the positioning holes 2 at the corresponding positions, and then the height of the vertical frame 13 can be adjusted to adjust the vertical height between the second vertical plate 14 and the first mounting frame 7, which is convenient for use with buckled flanges of different diameters.
