[0033] The outer wall of the circular frame 9 is fixedly connected with a ring-shaped rotating mechanism 23, which is mainly composed of a motor and a rotating transmission structure and can drive the telescopic tapping device 1 to rotate beside the circular frame 9. It is a mature technology in the prior art and will not be described in detail here.

It is a mature technology in the prior art and will not be described in detail here.

[0034] The driving mechanism includes a driving motor 17. An upper circular groove is opened on the side wall of the circular frame 9. The driving motor 17 is fixedly connected to the inner side of the upper circular groove. The side wall of the upper circular plate 12 is rotatably connected to the middle circular plate 18. Four arcuate grooves 19 are opened on the side wall of the middle circular plate 18 at equal intervals. The distances from the two ends of each arcuate groove 19 to the center of the middle circular plate 18 are different. The inner side of the upper straight groove 13 is slidably connected to the moving frame 14.

The side wall of the middle circular plate 18 is fixedly connected to the gear ring 20. The output end of the driving motor 17 is fixedly connected to a gear 22 that meshes with the gear ring 20.

[0035] The lifting mechanism includes a lifting motor 27, and the inner side of the fixed frame 4 is rotatably connected to a screw rod 28, which is threadedly connected to the inner side of the lifting frame 5. A pair of lifting motors 27 are provided, and the output end of the lifting motor 27 passes through the top of the fixed frame 4 and is fixedly connected to the top of the screw rod 28. The lifting mechanism facilitates the rapid lifting of the circular frame 9 to the position where the workpiece needs to be tapped;

[0036] The electromagnetic clamp 3 is arranged beside the movable guide rail 2. A pair of positioning blocks 16 for positioning the workpiece are fixedly connected to the electromagnetic clamp 3. The positioning blocks 16 can play a positioning role for large parts to avoid deviation when the parts are placed, which affects the subsequent normal positioning.

[0037] When tapping the connecting holes around the circular cavity of a large component, first place the large component between the positioning blocks 16 on the electromagnetic clamp 3 through the overhead crane, then control the electromagnetic clamp 3 to start adsorption and fix the component, then control the lifting motor 27 to start and drive the screw rod 28 to rotate, thereby driving the threaded lifting frame 5 to slide between the fixed frame 4, and at the same time drive the circular frame 9 and the telescopic tapper 1 to move, and move the circular frame 9 to the circular cavity of the component, and then control the electric telescopic cylinder 42 to start, driving the horizontal frame 6, the vertical frame 7, the positioning rod 15 and the telescopic tapper 1 to start. The retractable tapper 1 moves so that the positioning rod 15 is inserted into the circular cavity of the component, and at the same time, the retractable tapper 1 is driven to move to the side of the component, and then the drive motor 17 is controlled to start and drive the gear 22 to rotate, thereby driving the meshing gear ring 20 to rotate, and at the same time driving the middle circular plate 18 to rotate on the side wall of the upper circular plate 12. At the same time, since the circular frame 9 is inserted into the arc groove 19, and the distance between the two ends of the arc groove 19 and the center of the middle circular plate 18 gradually increases, then under the action of the rotation of the arc groove 19, the circular frame 9, the sliding frame 41 and the positioning rod 15 will be squeezed to move away from each other;

[0038] If the center of the circular frame 9 and the circular cavity of the part is in a deviated state at this time, the two positioning rods 15 will first contact the inner side of the circular cavity of the part, and the position of the part is fixed, so under the action of the continuous pressing force of the positioning rods 15, it will push the circular frame 9 and the sliding frame 41 to move, so that the sliding frame 41 slides in the longitudinal frame 7, and the upper and lower springs 11 are compressed and stretched, or the longitudinal frame 7 or the sliding block 8 slides in the horizontal frame 6, and the upper springs 10 on both sides are compressed or stretched, until the four positioning rods 15 are pressed on the inner side of the circular cavity of the part, so as to complete the rapid positioning of the telescopic tapping device 1, that is, the driving motor 17 is controlled to stop running, and then the horizontal mover 24 is controlled to install the predetermined program to adjust the position of the telescopic tapping device 1 (it is necessary to explain that through the machining drawing of the part, the distance between the circular cavity of the part and the connecting hole can be known, so that after the position of the circular frame 9 is positioned, the telescopic tapping device 1 can be accurately controlled to move to the side of the connecting hole), then the telescopic tapping device 1 is controlled to start tapping the connecting hole, and after the processing is completed, the annular rotating mechanism 23 is controlled to start driving the horizontal mover 24, the longitudinal mover 25, the moving plate 26 and the telescopic tapping device 1 to rotate, and the telescopic tapping device 1 is rotated to the next connecting hole, and the telescopic tapping device 1 is controlled to start tapping again. In this way, the automatic positioning and tapping of the connecting holes on the part can be realized.

[0039] In summary, through the design of the above structure, when tapping the large mechanical parts, the positioning rod 15 is first inserted into the circular cavity of the part, and then the driving mechanism drives the positioning rod 15 to move around. At this time, if the center of the circular frame 9 and the circular cavity of the part is in a deviated state, the two positioning rods 15 will be pressed on the inner side of the circular cavity of the part, so as to complete the rapid positioning of the telescopic tapping device 1, and then the annular rotating mechanism 23 and the telescopic tapping device 1 are started to tap the connecting holes on the outside of the part. In this way, the automatic positioning and tapping of the connecting holes on the large part can be realized, and the positioning of the circular cavities of different sizes can also be realized, greatly improving the flexibility and processing efficiency of the device.

[0040] On the basis of the above embodiment, it is found that the above structure can only automatically position and tap the connecting holes beside the circular cavities on the large parts, which is relatively limited. In order to solve the above problem, the above structure is further improved.

[0043] The outer wall of the positioning rod 15 is provided with a middle groove, the inner side of the circular frame 21 is fixedly connected with a middle plate 39 at a position inside the middle groove, and the side wall of the middle groove is fixedly connected with a return spring 40 between the side wall of the middle plate 39.

[0044] When the multiple connecting holes on the rectangular part need to be tapped, first, the rotary motor 36 is controlled to start to drive the disc 35 to rotate, and at the same time, the adjusting plate 37 is driven to rotate, at this time, the inclined surface of the adjusting plate 37 extrudes the arc surface of two L-shaped rods 34, so that the L-shaped rods 34 slide in the U-shaped frame 33 and compress the return springs 38, at the same time, through the movement of the L-shaped rods 34, the inclined surface of the L-shaped rod 34 extrudes the inclined surface of the right-angle block 32, so that two right-angle blocks 32 and extrusion blocks 30 slide in the rectangular groove and compress the extrusion springs 31, then the inclined surface of the extrusion block 30 moves to the side of the positioning rod 15, and gradually releases the extrusion on the positioning rod 15, then the positioning rod 15 is pulled to slide to the side of the lifting frame 5 under the elastic force of the return spring 40, at this time, the positioning rod 15 moves along the inclined surface of the extrusion block 30, and then the part of the two positioning rods 15 extending out of the upper circular plate 12 is retracted (it should be noted that, according to the shape of the part, the positioning position of the positioning rod 15 can be selected, when the other two positioning rods 15 need to be retracted, the rotary motor 36 is controlled to continue to start, and correspondingly, the L-shaped rods 34 fall off the adjusting plate 37, then the adjusting plate 37 is rotated to the other two groups of L-shaped rods 34, and the above process is repeated until the positioning rod 15 that needs to be retracted is extruded);

[0045] Then the lifting mechanism moves the round frame 9 to the side of the part connecting hole, and then controls the electric telescopic cylinder 42 to start, moves the two extended positioning rods 15 to the outside of the rectangular part, and then controls the driving motor 17 to reverse rotation, extrudes the two positioning rods 15 to the middle, and then extrudes the bottom end and the side wall of the rectangular part through the positioning rod 15, at this time, the upper spring 10 or the lower spring 11 is extruded and stretched as in the above operation, so as to determine the position of the round frame 9, finally, according to the size of the connecting hole and the outside and the top end of the part drawing, the position of the connecting hole is calculated, then the horizontal mover 24 and the vertical mover 25 are controlled to start, and the telescopic tapping device 1 is moved to the side of the connecting hole, and then the telescopic tapping device 1 is controlled to start to automatically tap the connecting hole.

[0046] In summary, through the design of the above structure, two positioning rods 15 can be retracted, and the other two positioning rods 15 are extruded to the middle through the driving mechanism, so that the positioning rods 15 are extruded and fitted on the bottom end and the side wall of the rectangular part respectively, so as to complete the automatic positioning of the rectangular workpiece, once the positioning is completed, the telescopic tapping device 1 can perform tapping operation on each hole position of the rectangular workpiece according to the preset program, ensure the accuracy and consistency of thread processing, greatly improve the production efficiency and processing quality, and make the equipment flexible, improve the application range of the device.
