Description

Technical Field

[0001] The present invention relates to the technical field of fastener tapping, and more specifically, to a multi-station fastener production and manufacturing tapping machine. Background Art

[0002] Fasteners such as bolts, nuts, screws, etc. are one of the most common components in industrial production and are widely used in multiple fields such as machinery manufacturing, automotive industry, construction engineering, aerospace, etc. The quality of fasteners directly affects the assembly quality and service life of the final product. In the production process of fasteners, the processing of threaded holes is a crucial link, and tapping is a common method for processing threaded holes. Tapping is a technique of cutting internal threads on a workpiece by rotating a cutting tool, such as a tap.

[0003] In order to improve the tapping efficiency, a multi-station tapping machine is usually set up. The existing multi-station tapping machine generally drives the fasteners to move in a circular motion through a turntable, so that multiple fasteners can sequentially pass through the bottom of the tap of the tapping machine for tapping. However, as the use time increases, components such as the turntable, guiding system, and driving system of the tapping machine may be worn, resulting in a decrease in positioning accuracy. The movement of the turntable driving the fasteners is no longer completely accurate, causing slight deviation of the fasteners during rotation, thereby affecting the centering of tapping.

[0020] The multi-station fastener production and manufacturing tapping machine provided by the present invention has the following beneficial effects:

[0021] 1. By setting up a tapping mechanism, the second motor can drive the first rotating shaft to rotate, driving the first gear to drive the gear ring and the placement disk to rotate, and sequentially sending the nuts in the placement cavity to the bottom of the tapping machine. Subsequently, the first motor drives the tapping machine to descend to tap the nuts.

[0022] 2. By setting up a fixing mechanism, after the nuts to be tapped are conveyed to the placement cavity through the feeding belt, as the placement disk rotates, the contact ring gradually rotates to the convex surface of the elliptical block, thereby driving the moving frame to move towards the placement cavity, and squeezing the wedge surface of the first driving plate through the driving shaft, driving the two first clamping blocks to move towards the surface of the nut to clamp and fix the nut. Subsequently, when the first motor drives the tapping machine to descend to tap the nuts, the mounting seat squeezes the pressing plate and drives the pressing plate to move downward, squeezing the wedge part of the second driving plate through the squeezing block, thereby driving the second clamping block to move towards the surface of the nut to perform secondary positioning on the nut, ensuring the tapping quality.

[0023] 3. By setting up a chip removal mechanism, in the initial state, the coolant in the box body can be sent into the first nozzle through the first water pipe and the third water pipe by the water pump to wash the tap, avoiding debris remaining on the surface of the tap and ensuring the tapping quality; when the first motor drives the tapping machine to descend to tap the nuts, it drives the second gear to drive the rotating wheel to rotate by 90 degrees, driving the three-way valve to rotate synchronously, making the second water pipe communicate with the third water pipe, and then the coolant can be sent into the second nozzle to wash the debris on the surface of the nut, facilitating cleaning.

[0047] In a preferred embodiment, in the initial state, the cutting fluid in the box body 503 can be sent into the first nozzle 501 through the first water pipe 505 and the third water pipe 507 by the water pump 504 to wash the tap, avoiding debris remaining on the surface of the tap and ensuring the tapping quality; when the first motor 303 drives the tapping machine 305 to descend to tap the nut, the second gear 322 is driven to drive the runner 320 to rotate by 90 degrees, driving the three-way valve 508 to rotate synchronously, so that the second water pipe 506 is communicated with the third water pipe 507, and the cutting fluid can be sent into the second nozzle 502 to wash the debris on the surface of the nut, facilitating cleaning.

[0048] Specifically, the working principle of the multi-station fastener production and manufacturing tapping machine is as follows: during use, the nut to be tapped can be conveyed to the placement cavity 309 through the feeding belt 2, and the first rotating shaft 311 can be driven to rotate by the second motor 313, driving the first gear 312 to drive the gear ring 310 and the placement disk 307 to rotate, and the nuts in the placement cavity 309 are sequentially sent to the bottom of the tapping machine 305. Subsequently, the tapping machine 305 is driven to descend by the first motor 303 to tap the nut. The mounting seat 304 squeezes the pressing plate 316 and drives the pressing plate 316 to move downward, thereby driving the second gear 322 to drive the runner 320 to rotate by 90 degrees through the first toothed plate 319, and driving the positioning plate 325 to move upward through the eccentric shaft 323, so that the positioning rod 314 is inserted into the positioning groove 326 to position the placement disk 307, realizing the centering of the nut and the tapping machine 305 and ensuring the tapping quality.

[0049] After the nut to be tapped is conveyed to the placement cavity 309 through the feeding belt 2, as the placement disc 307 rotates, the contact ring 409 gradually rotates to the convex surface of the elliptical block 410, thereby driving the moving frame 405 to move towards the placement cavity 309, and squeezing the wedge surface of the first driving plate 402 through the driving shaft 406, driving the first clamping blocks 401 on both sides to move towards the surface of the nut to clamp and fix the nut. Subsequently, when the first motor 303 drives the tapping machine 305 to descend to tap the nut, the mounting seat 304 squeezes the pressing plate 316 and drives the pressing plate 316 to move downward, squeezing the wedge part of the second driving plate 415 through the squeezing block 418, thereby driving the second clamping block 414 to move towards the surface of the nut to perform secondary positioning on the nut and ensure the tapping quality.

[0050] In the initial state, the cutting fluid in the box body 503 can be sent into the first nozzle 501 through the first water pipe 505 and the third water pipe 507 by the water pump 504 to wash the tap, avoiding debris remaining on the surface of the tap and ensuring the tapping quality; when the first motor 303 drives the tapping machine 305 to descend to tap the nut, it drives the second gear 322 to drive the runner 320 to rotate 90 degrees, driving the three-way valve 508 to rotate synchronously, making the second water pipe 506 communicate with the third water pipe 507, and then the cutting fluid can be sent into the second nozzle 502 to wash the debris on the surface of the nut for easy cleaning.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
