Detailed Description of the Invention

[0030] The following will further describe this application in detail with reference to the attached Figures 1-4 drawings.

[0031] Please refer to Figures 1-4 , an automatic tapping machine, including a base 1, a rotating component 2 installed on the base 1 for driving the workpiece to rotate, and a tapping component 4 arranged on one side of the rotating component 2 for tapping. The rotating component 2 is also provided with a clamping component 5 for positioning the workpiece;

[0032] The rotating assembly 2 includes a workbench 201. A driving gear ring 204 is arranged at the bottom of the workbench 201, and a driving gear 202 meshing with the driving gear ring 204 is arranged inside the driving gear ring 204. The lower part of the driving gear 202 is connected to the power output end of a stepping motor 203.

[0033] Six groups of pneumatic fingers 3 are evenly distributed at equal intervals on the top of the workbench 201. A discharge chute 6 is arranged on one side of one group of pneumatic fingers 3, and a feeding conveyor belt 7 is arranged on one side of another group of pneumatic fingers 3. The tapping assembly 4 is located on one side of the remaining pneumatic fingers 3.

[0034] With the above technical solution, multiple groups of workpieces can be placed by the six groups of pneumatic fingers 3 arranged. The workpieces reach inside one group of pneumatic fingers 3 through the feeding conveyor belt 7 for clamping. As the rotating assembly 2 rotates, this group of workpieces reaches the position of the first tapping assembly 4. By changing the size of the tapping assembly 4, complex tapping processing can be achieved. After the workpieces rotate with the rotating assembly 2, they reach the position of the discharge chute 6 and are discharged outward through the discharge chute 6, improving the tapping efficiency.

[0035] Refer to Figure 1 As shown, the tapping assembly 4 includes a feeding base 401. An installation base plate 402 is arranged above the feeding base 401, and an electric slide rail is arranged at the connection between the installation base plate 402 and the feeding base 401. A servo motor 403 is installed above the installation base plate 402 through bolts, and a tapping screw 404 is connected to the power output end of the servo motor 403. By arranging the feeding base 401, the servo motor 403 can be driven to move towards the pneumatic fingers 3 under the action of the electric slide rail. The axial direction of the tapping screw 404 faces the pneumatic fingers 3 respectively. By arranging the tapping screw 404, the workpieces placed in the pneumatic fingers 3 can be tapped.

[0036] Refer to Figure 2 and Figure 3, the clamping assembly 5 includes a lifting cylinder 509 installed at the bottom of the base 1. The telescopic end of the lifting cylinder 509 is provided with a lifting column 508, and a guiding sleeve 506 for guiding the lifting column 508 is sleeved outside the lifting column 508. The top of the guiding sleeve 506 is fixedly provided with a support plate 501. By setting the lifting cylinder 509, the lifting column 508 can be pushed to lift, so as to perform secondary clamping and positioning on the workpiece. The top of the lifting column 508 penetrates through the guiding sleeve 506 and is installed with a lifting plate 507, and the top of the lifting plate 507 is installed with a support plate 501. The periphery of the support plate 501 is provided with a support frame 502 adapted to the position of the pneumatic finger 3. The movement of the lifting column 508 is guided by the guiding sleeve 506. A clamping spring 503 is provided on one side of the support frame 502 close to the pneumatic finger 3, and a guiding telescopic rod 504 is inserted inside the clamping spring 503. By setting the clamping spring 503 and the guiding telescopic rod 504, a certain buffering effect can be achieved to avoid damaging the workpiece. The end of the guiding telescopic rod 504 is connected with a clamping head 505, and the clamping head 505 is parallel to the pneumatic finger 3. By setting the clamping head 505 made of rubber material, it can contact the workpiece placed in the pneumatic finger 3, so as to protect the workpiece.

[0037] The implementation principle of this application is as follows: When in use, first, the workpiece reaches inside one group of pneumatic fingers 3 through the feeding conveyor belt 7. In order to facilitate the workpiece in the feeding conveyor belt 7 to enter the pneumatic fingers 3, a mechanical claw can be set on one side of the feeding conveyor belt 7 to clamp the workpiece and place it inside the pneumatic fingers 3. Similarly, a mechanical claw can also be set on one side of the discharge chute 6 to clamp the workpiece and place it inside the discharge chute 6. The stepping motor 203 drives the driving gear 202 to rotate, which can drive the driving gear ring 204 to rotate, and the driving gear ring 204 can drive the workbench 201 to rotate. At this time, the second group of pneumatic fingers 3 reaches the position of the feeding conveyor belt 7, and the first group of pneumatic fingers 3 reaches the position of the first tapping assembly 4. The stepping motor 203 stops working, and the lifting cylinder 509 is started. The lifting cylinder 509 can drive the support frame 502 to descend through the lifting column 508, so that the support frame 502 moves in the direction close to the pneumatic finger 3 until the clamping head 505 can contact the workpiece placed in the pneumatic finger 3. At this time, the clamping spring 503 and the guiding telescopic rod 504 can play a certain buffering role to avoid damaging the workpiece;

[0038] Under the action of the mounting base plate 402, the servo motor 403 can slide on the feeding base 401, and the servo motor 403 drives the tapping screw 404 to rotate, so as to operate on the workpiece. The diameter of the tapping screw 404 can be replaced according to needs. At the same time, the feeding process of the tapping screw 404 can also be changed by adjusting the moving process of the electric slide rail. Thus, complex tapping operations can be realized through multiple tapping assemblies 4. After the workpiece is successively processed by the tapping screw 404, it reaches the position of the discharge chute 6 and is discharged outwards through the discharge chute 6, improving the tapping efficiency.

[0039] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
