Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing equipment, and in particular to a tapping machine used for bolt production. Background Art

[0002] A tapping machine is a mechanical device used to process threads. It is widely used in manufacturing and engineering fields. It cuts threads on the surface of the workpiece by rotating and advancing it. It is often used to manufacture fasteners such as bolts and nuts. The tapping machine can adjust the rotation speed and feed speed of the tool and workpiece according to needs to accurately control the specifications and quality of the thread. It is simple and efficient to operate, and can greatly improve production efficiency and product quality. It is one of the indispensable key equipment in the modern manufacturing process.

[0003] When producing bolts, operators often use tapping machines to process threads on the outer surface of the bolts. In actual use, although the existing tapping machines have basic thread processing functions, they can generally only process threads on one type of bolt. If the operator needs to process bolts of other sizes, the tapping die needs to be manually replaced, and the replacement of the tapping die is very time-consuming and cumbersome, which greatly increases the labor burden of the operator. Therefore, it is necessary to improve it. Utility Model Content

[0035] When the No. 1 motor 6 is running, the rotating shaft 7 and the No. 1 gear 8 will start to rotate. Since the No. 1 gear 8 and the outer surfaces of the toothed plate 9 are meshed with each other, the toothed plate 9 and the mounting plate 5 will start to move left and right driven by the No. 1 gear 8.

[0036] Among them, a No. 1 fixing seat 14 is fixedly connected to the left side of the upper surface of the processing table 1, and a die 10 is fixedly installed on the inner surface of the mounting plate 5.

At the same time, the three clamps 23 start to move toward the bolt under the drive of the other ends of the three connecting rods 22. Finally, when the three clamps 23 contact the outer surface of the bolt, the bolt will be fixed in the current position by the three clamps 23.

[0056] At this time, the operator starts the No. 1 motor 6 again. As the No. 1 motor 6 runs, the rotating shaft 7 and the No. 1 gear 8 will start to rotate, and the rotation of the No. 1 gear 8 will drive the tooth plate 9, so that the tooth plate 9 and the mounting plate 5 start to move left and right under the limit of the limit clamp 4, until the die 10 that meets the thread processing requirements is aligned with the bolt, and then the operator starts the No. 2 motor 11 and the No. 3 motor 15 again. The operation of the No. 2 motor 11 will cause the lead screw 12 to start rotating. At this time, the moving platform 2 as a whole will start to move toward the bolt direction driven by the lead screw 12, and the operation of the No. 3 motor 15 will cause the round shaft 16, the connecting circular plate 17, the hollow box 18 as a whole and the bolt to start rotating. Finally, under the joint action of the bolt and the die 10, the die 10 will complete the thread processing on the outer surface of the bolt.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
