A multi-station fastener manufacturing tapping machine

Abstract

This invention provides a multi-station fastener tapping machine, belonging to the field of fastener tapping technology. The multi-station fastener tapping machine includes a base and a conveyor belt. The conveyor belt is installed on the surface of the base, and a tapping mechanism is mounted on the base surface. The tapping mechanism includes a frame, a fixed cylinder, a gear ring, and a drive frame. The frame is fixedly installed on the base surface, and a lead screw is rotatably installed inside the frame cavity. By setting up the tapping mechanism, a second motor drives a first rotating shaft to rotate, causing a placement disc to rotate. Nuts in the placement cavity are sequentially fed to the bottom of the tapping machine. The tapping machine then descends to tap the nuts. The mounting base presses against the pressure plate and drives the pressure plate downwards. This, in turn, drives a second gear via a first gear plate to rotate a rotating wheel 90 degrees. An eccentric shaft drives a positioning plate to move upwards, causing a positioning rod to insert into a positioning groove, positioning the placement disc and achieving alignment between the nut and the tapping machine, ensuring tapping quality.

Description

Technical Field

[0001] This invention relates to the field of fastener tapping technology, and more specifically, to a multi-station fastener manufacturing tapping machine. Background Technology

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

[0003] To improve tapping efficiency, a multi-station tapping machine is usually installed. Existing multi-station tapping machines generally use a turntable to drive the fasteners to move in a circular motion, so that multiple fasteners can pass through the bottom of the tap of the tapping machine in sequence for tapping. However, with the increase of use time, the turntable, guide system and drive system of the tapping machine may wear down, resulting in a decrease in positioning accuracy. The movement of the fasteners driven by the turntable is no longer completely accurate, causing the fasteners to deviate slightly during rotation, which in turn affects the centering of the tapping. Summary of the Invention

[0020] The present invention provides a multi-station fastener manufacturing tapping machine, the beneficial effects of which include:

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

[0022] 2. By setting up a fixing mechanism, the nut to be tapped is transported to the placement cavity by the conveyor belt. As the placement plate rotates, the contact ring gradually rotates to the convex part of the elliptical block, thereby driving the moving frame to move towards the placement cavity. The drive shaft presses the wedge-shaped surface of the first drive plate, driving the first clamping blocks on both sides to move towards the nut surface and clamp and fix the nut. Then, the first motor drives the tapping machine to descend. When tapping the nut, the mounting base presses the pressure plate and drives the pressure plate to move down. The pressing block presses the wedge-shaped part of the second drive plate, thereby driving the second clamping block to move towards the nut surface and perform secondary positioning of the nut to ensure the tapping quality.

[0023] 3. By setting up a chip removal mechanism, in the initial state, the cutting fluid in the housing can be sent to the first nozzle through the first and third water pipes by the water pump to rinse the tap and prevent chips from remaining on the tap surface, thus ensuring the tapping quality. When the first motor drives the tapping machine to descend and tap the nut, it drives the second gear to rotate the wheel 90 degrees, which drives the three-way valve to rotate synchronously, so that the second and third water pipes are connected, and the cutting fluid can be sent to the second nozzle to rinse the chips on the surface of the nut for easy cleaning.

[0039] Reference Figures 1-6As shown, in a preferred embodiment, positioning rods 314 are symmetrically fixedly installed at the bottom of the gear ring 310 for positioning the placement tray 307.

When the first motor 303 drives the tapping machine 305 to descend and tap the nut, the mounting seat 304 presses the pressure plate 316 and drives the pressure plate 316 to move downward. This drives the second gear 322 through the first toothed plate 319 to rotate the rotating wheel 320 by 90 degrees. The eccentric shaft 323 drives the positioning plate 325 to move upward, so that the positioning rod 314 is inserted into the positioning groove 326 to position the placement plate 307, thereby achieving the alignment of the nut and the tapping machine 305 and ensuring the tapping quality.

[0040] In a preferred embodiment, during use, the nut to be tapped is conveyed to the placement cavity 309 by the conveyor belt 2, and the first rotating shaft 311 is driven to rotate by the second motor 313, which drives the first gear 312 to drive the gear ring 310 and the placement plate 307 to rotate, so that the nuts in the placement cavity 309 are sequentially sent to the bottom of the tapping machine 305. Then, the tapping machine 305 is driven to descend by the first motor 303 to tap the nut. The mounting seat 304 presses the pressure plate 316 and drives the pressure plate 316 to move down, thereby driving the second gear 322 through the first toothed plate 319 to drive the rotating wheel 320 to rotate 90 degrees, and driving the positioning plate 325 to move up through the eccentric shaft 323, so that the positioning rod 314 is inserted into the positioning groove 326 to position the placement plate 307, realizing the alignment of the nut and the tapping machine 305 and ensuring the tapping quality.

[0041] Reference Figures 1-8As shown, in a preferred embodiment, a fixing mechanism 4 is installed on the surface of the base 1 to fix the nut in the placement cavity 309.

A first connecting block 403 is fixedly installed at the bottom of the first driving plate 402. A second spring 404 is fixedly installed in the inner cavity of the placement tray 307. One end of the second spring 404 is fixedly connected to the placement tray 307, and the other end of the second spring 404 is fixedly connected to the first connecting block 403, for driving the first clamping block 401 to move away from the nut.

[0042] Reference Figures 1-8 As shown, in a preferred embodiment, a movable frame 405 is symmetrically slidably mounted on the surface of the placement tray 307. A drive shaft 406 is symmetrically fixedly mounted on the bottom of the movable frame 405. The drive shaft 406 is in close contact with the surface of the first drive plate 402 and is used to drive the first clamping block 401 to move towards the nut. A drive rod 407 is fixedly mounted on the side wall of the movable frame 405. A connecting frame 408 is fixedly mounted on the surface of the placement tray 307. The drive rod 407 is slidably connected to the connecting frame 408. A contact ring 409 is fixedly mounted on the other end of the drive rod 407.

The surface of the bearing ring 308 has a notch 413 for feeding. After the nut to be tapped is transported to the placement cavity 309 by the conveyor belt 2, as the placement plate 307 rotates, the contact ring 409 gradually rotates to the convex part of the elliptical block 410, thereby driving the moving frame 405 to move towards the placement cavity 309, and pressing the wedge surface of the first drive plate 402 through the drive shaft 406, driving the first clamping blocks 401 on both sides to move towards the nut surface, clamping and fixing the nut to ensure the tapping quality.

A pressing block 418 is fixedly mounted on the side wall of the pressure plate 316. The pressing block 418 is also wedge-shaped and is used to drive the second driving plate 415 to move outward. When the first motor 303 drives the tapping machine 305 to descend and tap the nut, the mounting seat 304 presses the pressure plate 316 and drives the pressure plate 316 to move downward. The pressing block 418 presses the wedge-shaped part of the second driving plate 415, thereby driving the second clamping block 414 to move towards the nut surface for secondary positioning of the nut, ensuring the tapping quality.

[0044] In a preferred embodiment, after the nut to be tapped is conveyed to the placement cavity 309 by the conveyor belt 2, as the placement plate 307 rotates, the contact ring 409 gradually rotates to the convex part of the elliptical block 410, thereby driving the moving frame 405 to move towards the placement cavity 309, and pressing the wedge-shaped surface of the first drive plate 402 through the drive shaft 406, driving the first clamping blocks 401 on both sides to move towards the nut surface to clamp and fix the nut. Subsequently, the first motor 303 drives the tapping machine 305 to descend. When tapping the nut, the mounting base 304 presses the pressure plate 316 and drives the pressure plate 316 to move down. The pressing block 418 presses the wedge-shaped part of the second drive plate 415, thereby driving the second clamping block 414 to move towards the nut surface to perform secondary positioning of the nut and ensure the tapping quality.

[0045] Reference Figures 1-10 As shown, in a preferred embodiment, a chip removal mechanism 5 is installed in the inner cavity of the base 1 to remove tapping chips. The chip removal mechanism 5 includes a first nozzle 501 and a second nozzle 502. Both the first nozzle 501 and the second nozzle 502 are installed on the side wall of the support 315. The first nozzle 501 is located on the side of the tap and is used to remove chips from the surface of the tap. The second nozzle 502 is located on the side of the placement plate 307 and is used to remove chips from the surface of the nut.

[0046] Reference Figures 1-10As shown, in a preferred embodiment, the inner cavity of the base 1 is provided with a housing 503 for storing cutting fluid. A water pump 504 is installed in the inner cavity of the housing 503. One end of the first nozzle 501 is connected to a first water pipe 505, one end of the second nozzle 502 is connected to a second water pipe 506, and the outlet end of the water pump 504 is connected to a third water pipe 507. A three-way valve 508 is connected between the first water pipe 505, the second water pipe 506, and the third water pipe 507. A third rotating shaft 509 is connected between the three-way valve 508 and the second gear 322.

[0047] In a preferred embodiment, initially, the cutting fluid in the housing 503 is pumped by the water pump 504 into the first nozzle 501 via the first water pipe 505 and the third water pipe 507 to rinse the tap, preventing debris from remaining on the tap surface and ensuring tapping quality. When the first motor 303 drives the tapping machine 305 to descend and tap the nut, the second gear 322 drives the rotating wheel 320 to rotate 90 degrees, which in turn drives the three-way valve 508 to rotate synchronously, making the second water pipe 506 and the third water pipe 507 connected, so that the cutting fluid can be sent into the second nozzle 502 to rinse the debris on the nut surface for easy cleaning.

[0048] Specifically, the working principle of this multi-station fastener manufacturing tapping machine is as follows: During use, the nut to be tapped can be transported to the placement cavity 309 by the conveyor belt 2, and the first rotating shaft 311 can be driven to rotate by the second motor 313, which drives the first gear 312 to drive the gear ring 310 and the placement plate 307 to rotate, so that the nuts in the placement cavity 309 are sent to the bottom of the tapping machine 305 in sequence. Then, the tapping machine 305 is driven to descend by the first motor 303 to tap the nut. The mounting seat 304 squeezes the pressure plate 316 and drives the pressure plate 316 to move down, thereby driving the second gear 322 through the first toothed plate 319 to drive the rotating wheel 320 to rotate 90 degrees, and driving the positioning plate 325 to move up through the eccentric shaft 323, so that the positioning rod 314 is inserted into the positioning groove 326 to position the placement plate 307, realize the alignment of the nut and the tapping machine 305, and ensure the tapping quality.

[0049] After the nut to be tapped is conveyed to the placement cavity 309 by the conveyor belt 2, as the placement plate 307 rotates, the contact ring 409 gradually rotates to the convex part of the elliptical block 410, thereby driving the moving frame 405 to move towards the placement cavity 309. The drive shaft 406 presses the wedge-shaped surface of the first drive plate 402, driving the first clamping blocks 401 on both sides to move towards the nut surface to clamp and fix the nut. Then, the first motor 303 drives the tapping machine 305 to descend. When tapping the nut, the mounting base 304 presses the pressure plate 316 and drives the pressure plate 316 to move down. The pressing block 418 presses the wedge-shaped part of the second drive plate 415, thereby driving the second clamping block 414 to move towards the nut surface to perform secondary positioning of the nut and ensure the tapping quality.

[0050] In the initial state, the cutting fluid in the housing 503 can be sent to the first nozzle 501 through the first water pipe 505 and the third water pipe 507 by the water pump 504 to rinse the tap and prevent debris from remaining on the tap surface, thus ensuring the tapping quality. When the first motor 303 drives the tapping machine 305 to descend and tap the nut, it drives the second gear 322 to rotate the wheel 320 ninety degrees, which drives the three-way valve 508 to rotate synchronously, so that the second water pipe 506 and the third water pipe 507 are connected, and the cutting fluid can be sent to the second nozzle 502 to rinse the debris on the surface of the nut for easy cleaning.

[0051] The above are merely 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 within the protection scope of the present invention.
