Description

Technical Field

[0001] This invention relates to the field of machining tools, specifically a tool for machining feed ring die forming holes. Background Technology

[0002] In the feed processing industry, feed ring die forming hole machining tools play a crucial role. With the continuous development of feed processing technology, the requirements for machining accuracy and efficiency of feed ring die forming holes are becoming increasingly stringent. However, existing feed ring die forming hole machining tools have some significant shortcomings in design and use, particularly in tool changing operations.

[0003] Currently, the cutting tools commonly used for machining feed ring die forming holes on the market are typically of the traditional fixed type. This replacement method is cumbersome and requires a significant amount of time and manpower. First, the operator needs to stop the machine, then manually remove the old tool, install the new tool, and make the necessary adjustments. This process is not only inefficient but also prone to introducing human error, affecting machining accuracy.

However, existing machining tools are often only suitable for one or a few specific feed ring dies, failing to meet diverse machining needs. When machining feed ring dies of different sizes, frequent tool changes are required, further increasing operational difficulty and cost.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-8 A feed ring die forming hole machining tool includes a ring die machine tool transmission end 1, a tool mounting cylinder 2, a ring die hole-opening tool 3, and a mounting cap 4. The tool mounting cylinder 2 is fixedly mounted on the movable end of the ring die machine tool transmission end 1. The ring die hole-opening tool 3 is movably connected to the bottom end of the tool mounting cylinder 2, and the mounting cap 4 is fixedly connected to the middle end of the ring die hole-opening tool 3. The tool also includes: The transmission end 1 of the ring die machine tool is equipped with a clamping device for limiting and fixing the ring die hole-opening tool 3.

[0024] Furthermore, the clamping device includes a clamping cylinder 5 and a blocking ring 6. The clamping cylinder 5 is fixedly connected inside the tool mounting cylinder 2, and the blocking ring 6 is fixedly connected to the outer surface of the tool mounting cylinder 2. The top of the ring die opening tool 3 enters the clamping cylinder 5 inside the tool mounting cylinder 2. The clamping spring end of the clamping cylinder 5 clamps and limits the ring die opening tool 3, preventing the ring die opening tool 3 from shaking inside the clamping cylinder 5 and affecting the installation effect of the tool.

[0025] Furthermore, the outer surface of the tool mounting cylinder 2 is threaded to the bottom of the blocking ring 6, and the outer surface of the tool mounting cylinder 2 is movably connected to the top of the blocking ring 6. The outer surface of the movable ring 7 is fixedly connected to a connecting rod 8. One end of the connecting rod 8 is fixedly connected to a threaded tube 9, and the inside of the threaded tube 9 is threaded. The inside of the threaded tube 9 is threaded to a threaded rod 10, and the bottom end of the threaded rod 10 is fixedly mounted on the movable end of the motor 11.

[0026] Furthermore, the clamping cylinder 5 is formed by a tapered cylinder and a mounting ring fixedly connected together. The mounting ring is fixedly connected to the inner wall of the top end of the tool mounting cylinder 2, and the thinner end of the tapered cylinder is fixedly connected to the mounting ring. The thicker end of the tapered cylinder is divided into four equal parts to form a clamping spring.

[0027] Furthermore, the top of the conversion plate 27 has four placement openings 28, and a mounting cap 4 is placed on the top of each of the four placement openings 28. Ring die drilling tools 3 with different drilling diameters are placed in the four placement openings 28 through the four mounting caps 4. A groove 29 is opened on each of the four sides of the conversion plate 27, and an arc groove is opened between the four sides of the conversion plate 27 corresponding to the four grooves 29. A crank rod 19 is movably connected to one side of the arc groove of the conversion plate 27.

[0028] Furthermore, each of the four placement ports 28 has a friction layer 30 fixedly connected inside, and all four friction layers 30 are annular, with the inner surface of each friction layer 30 being triangular, and all four friction layers 30 are made of rubber.

[0029] Furthermore, the drive device includes a transmission rod 12, a connecting plate 13, a rotating handle 14, a fixing plate 15, a placement ring 21, a linkage rod 22, a connecting plate 23, a rotating rod 24, a toggle rod 25, and a limit rod 26. The bottom end of the motor 11 is fixedly connected to the transmission rod 12, the bottom end of the transmission rod 12 is movably connected to the fixing plate 15, and the bottom end of the transmission rod 12 passes through the fixing plate 15 to fixally install the connecting plate 13. A rotating handle 14 is fixedly connected to one side of the connecting plate 13. A placement ring 21 is movably connected to the middle end of the transmission rod 12. Two linkage rods 22 are fixedly connected to one side of the placement ring 21. A connecting plate 23 is movably installed on the top of the two linkage rods 22, and the top end of the connecting plate 23 is movably connected to... There is a rotating rod 24, and a toggle rod 25 is fixedly installed at one end of the rotating rod 24. A limit rod 26 is fixedly connected to the top of one end of the fixed plate 15. The top of the limit rod 26 is movably connected to the bottom center point of the conversion disk 27. The rotating rod 24 is driven to rotate through the steel column via the third gear 18, thereby driving the toggle rod 25 fixedly connected to the rotating rod 24 to rotate, so that the top of the toggle rod 25 rotates into the groove 29 of the conversion disk 27. When one end of the toggle rod 25 continues to rotate, it drives the conversion disk 27 to rotate on the limit rod 26, thereby driving the ring die opening cutter 3 that requires the feed ring die opening size to rotate to the lower end of the cutter mounting cylinder 2, thereby realizing the automation of cutter conversion.

[0030] Furthermore, a first gear 16 is fixedly connected to the bottom of the placement ring 21 on the outer surface of the transmission rod 12, and a second gear 17 is meshed with one side of the first gear 16, and a third gear 18 is meshed with one side of the second gear 17. The top of the second gear 17 is movably connected to the bottom of one of the linkage rods 22 through a steel column, and the top of the third gear 18 is movably connected to one end of the rotating rod 24 through a steel column.

[0031] Furthermore, the crank 19 is arc-shaped, and a fixed rod 20 is fixedly connected to each end of the crank 19. One end of each fixed rod 20 is fixedly connected to the outer surface of the transmission rod 12, and the arc-shaped surface of the crank 19 fits into the arc-shaped groove of the conversion disk 27. By tightly fitting the outer surface of the crank 19 into the arc-shaped groove on the conversion disk 27, the transmission rod 12 can rotate stably, thereby controlling the distance between the drive device and the conversion disk 27, so that the actuating rod 25 can better actuate the conversion disk 27 through the groove 29 to rotate.

[0032] Furthermore, two function buttons 31 are movably installed on the bottom of the connecting plate 13. One function button 31 is marked with forward rotation, and the other function button 31 is marked with reverse rotation. The two function buttons 31 are connected to the drive end 1 of the ring die machine tool and the motor 11 respectively through wires. The movable ends of the drive end 1 of the ring die machine tool and the motor 11 rotate in the same direction.

[0033] Working principle: When punching and forming feed rings, firstly, rotating the handle 14 drives the transmission rod 12 to rotate via the connecting plate 13, thereby driving the first gear 16 to rotate. Through the meshing connection between the first gear 16 and the second gear 17, the second gear 17 rotates around the outer surface of the first gear 16, and the second gear 17 itself also rotates. Through the meshing connection between the second gear 17 and the third gear 18, the third gear 18 is driven to rotate. Then, when the second gear 17 drives the third gear 18 to rotate below the conversion plate 27, the third gear 18 drives the rotating rod 24 to rotate via the steel column, thereby driving the fixed connection on the rotating rod 24. The actuating lever 25 rotates, causing its top end to rotate into the groove 29 of the conversion disc 27. As one end of the actuating lever 25 continues to rotate, it causes the conversion disc 27 to rotate on the limiting rod 26, thereby driving the ring die opening cutter 3, which requires the feed ring die opening size, to rotate to the lower end of the cutter mounting cylinder 2. Simultaneously, during the rotation of the conveying rod 12, it drives the two fixed rods 20 to drive the curved rod 19 to rotate. By utilizing the outer surface of the curved rod 19 to tightly contact the arc groove on the conversion disc 27, the conveying rod 12 can rotate stably, thereby controlling the distance between the drive device and the conversion disc 27. This allows the actuating lever 25 to better rotate the conversion disc 27 through the groove 29. Then, the forward rotation button marked on the connecting disc 13 is pressed. Pressing button 31 causes the movable end of the ring die machine tool transmission end 1 and the motor 11 to rotate in the forward direction. This causes the movable end of the ring die machine tool transmission end 1 to drive the threaded rod 10 to rotate. Then, through the threaded connection between the threaded rod 10 and the threaded tube 9, the motor 11 drives the ring die punching tool 3 and the mounting cap 4 to move upward via the fixed plate 15, the limit rod 26, and the conversion disc 27. This causes the top of the ring die punching tool 3 to enter the clamping cylinder 5 inside the tool mounting cylinder 2. The clamping spring end of the clamping cylinder 5 clamps and limits the ring die punching tool 3. As the mounting cap 4 rises, the ring die machine tool transmission end 1 drives the tool mounting cylinder 2 to rotate, causing the threads inside the mounting cap 4 and the threads on the surface of the tool mounting cylinder 2 to rotate. The threaded connection between the threads allows the mounting cap 4 to pass through the friction layer 30 on the placement port 28. The friction between the outer surface of the mounting cap 4 and the friction layer 30 causes the mounting cap 4, along with the ring die drilling tool 3, to screw onto the bottom of the tool mounting cylinder 2. When the mounting cap 4 is fully tightened onto the tool mounting cylinder 2, the tool mounting cylinder 2 drives the ring die drilling tool 3 to rotate via the mounting cap 4, allowing the ring die drilling tool 3 to drill holes in the feed ring die. Conversely, pressing the reverse function button 31 on the bottom of the connecting plate 13 causes the ring die machine tool transmission end 1 and the motor 11 to rotate in opposite directions, and the conversion plate 27 moves downwards. When the mounting cap 4 passes through the placement port 28 on the conversion plate 27, the friction between the friction layer 30 and the mounting cap 4 is utilized.This causes the mounting cap 4 to disengage the ring die opening cutter 3 from the cutter mounting cylinder 2, thereby removing the mounting cap 4 along with the ring die opening cutter 3. This process is repeated to change the cutter to meet the requirements of different opening sizes in the feed ring die.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
