Description

Technical Field

[0001] This invention relates to the field of drill bit tooling equipment technology, and in particular to an automatic drill bit ring changing device. Background Technology

[0002] The drill bit collar is mainly used to determine the axial position of drill bits and other fixed-size cutting tools.

[0003] During actual use, the hole wall of the drill bit collar rubs against the cutting tool. When it can no longer meet the processing requirements, a new collar needs to be replaced.

[0004] In existing technologies, the replacement of the collar is mostly done by manually removing it. However, the manual removal method usually involves unlocking the collar from the drill bit, which cannot address situations where the drill bit cannot be removed due to collar damage.

[0005] In addition, in the prior art, there is a device that can remove the drill bit from the collar, but it is not possible to install a new collar on the existing device. It requires two separate devices to complete the task, which makes the mechanism of the device complex and inconvenient to use and maintain.

[0006] Therefore, solutions to the above problems are urgently needed. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic drill bit ring changing device that can automatically replace the ring. Moreover, the automatic drill bit ring changing device of this invention completes the ring replacement within a single ring changing chamber, has a simple structure, and is easy to maintain.

[0057] In existing technologies, the replacement of the collar is mostly done by manually removing it. However, the manual removal method usually involves unlocking the collar from the drill bit, which cannot address situations where the drill bit cannot be removed due to collar damage.

[0058] In addition, in the prior art, there is a device that can remove the drill bit from the collar, but it is not possible to install a new collar on the existing device. It requires two separate devices to complete the task, which makes the mechanism of the device complex and inconvenient to use and maintain.

[0059] Therefore, the actual problem solved by this invention is how to improve the structure of the automatic ring changing device in the automatic ring changing equipment for drill bits.

[0060] As an exemplary example of this embodiment, the drill bit to be processed in this embodiment is a drill bit with an old collar, and the finished product in this embodiment is a drill bit with a new collar. Figures 2 to 4 As shown, an automatic drill bit ring changing device includes:

[0061] A turntable device 1 has a movable turntable 11, on which a positioning fixture 12 is mounted for fixing the drill bit to be processed.

[0062] Positioning fixture 12 is provided with positioning hole 511. The drill bit to be processed is placed in positioning hole 511 to achieve positioning, thereby stabilizing the drill bit to be processed during transportation.

[0063] The feeding device 2 and the transferring device 3 are arranged around the turntable device 1. The feeding device 2 is used to transport and store the drill bit to be processed, and the transferring device 3 is used to transfer the drill bit to be processed to the positioning fixture 12.

[0064] The feeding device 2 transports the drill bit to be processed to the set position, and the transfer device 3 transfers the drill bit to be processed. This simplifies the mechanical setup structure for transferring the drill bit to be processed onto the positioning fixture 12, thereby saving setup costs.

[0065] The advance and retraction ring device 4 is located around the turntable device 1, that is, the advance and retraction ring device 4 is located on the rotation path of the turntable device 1. The advance and retraction ring device 4 is used to replace the collar on the drill bit to be processed.

[0066] The advancing / retreating ring device 4 includes:

[0067] The first positioning plate 41 has a ring-changing cavity 100 inside it;

[0068] The ejector mechanism 42 is located below the first positioning plate 41. The ejector mechanism 42 is used to lift the drill bit so as to separate the drill bit from the old collar.

[0069] A clamping mechanism 43 is disposed between the ejector mechanism 42 and the first positioning plate 41, and the clamping mechanism 43 is used to clamp the ejected drill bit;

[0070] The first pushing mechanism 44 is disposed on one side of the first positioning plate 41 and is used to push the new collar into the collar changing cavity 100.

[0071] The second pushing mechanism 45 is disposed on one side of the first positioning plate 41. The second pushing mechanism 45 is used to push the new collar to align it with the drill bit, and to push the old collar away and move it by pushing the new collar.

[0072] The pressing mechanism 46 is disposed above the first positioning plate 41. The pressing mechanism 46 is used to press down the drill bit so that the drill bit is embedded in the new collar.

[0073] When the positioning fixture 12, carrying the drill bit to be processed, moves into the ring-changing cavity 100 of the first positioning plate 41, the ejector mechanism 42 will push upwards, thereby separating the drill bit from the old collar. The clamping mechanism 43 clamps the ejected drill bit and places it at a high position. The first pushing mechanism 44 pushes the new collar into the ring-changing cavity 100, which is used to place the new collar in the ring-changing cavity 100. Then, the second pushing mechanism 45 pushes the new collar to be aligned with the drill bit, while simultaneously pushing open the old collar. The pressing mechanism 46 presses down the drill bit clamped by the clamping mechanism 43, so that the drill bit is embedded in the new collar. The replacement of the drill bit and collar can be completed within the ring-changing cavity 100.

[0074] This embodiment of an automatic drill bit ring changing device includes a turntable device 1, a feeding device 2, a transferring device 3, and a ring-advancing / retracting device 4. By arranging the feeding device 2, the transferring device 3, and the ring-advancing / retracting device 4 around the turntable device 1, the rotation of the turntable device 1 allows the drill bit with the ring to move to various work positions, enabling the ring-advancing / retracting device 4 to perform ring-advancing / retracting operations on the drill bit. Furthermore, a first positioning plate 41 is constructed within the ring-advancing / retracting device 4, and a ring-changing cavity 100 is provided within the first positioning plate 41. The positioning fixture 12 moves the drill bit to be processed into the ring-changing cavity 100 as the turntable 11 rotates. The ring is changed within the ring-changing cavity 100 by the ejector mechanism 42 and the pressing mechanism 46. This reduces the need for additional workpiece setup, simplifies the overall structure of the equipment, and the automatic drill bit ring changing device of this invention replaces manual ring changing, thus improving work efficiency.

[0075] In this embodiment, as Figure 5 As shown, the first pushing mechanism 44 includes a first pushing plate 441 and a first pushing plate cylinder 442; the second pushing mechanism 45 includes a second pushing plate 451 and a second pushing plate cylinder 452.

[0076] The ring-changing cavity 100 includes a first channel 101 and a second channel 102 arranged at an angle to each other;

[0077] The first pusher cylinder 442 can push the first pusher 441 into the first channel 101, and the second pusher cylinder 452 can push the second pusher 451 into the second channel 102.

[0078] Specifically, the first channel 101 and the second channel 102 are arranged perpendicularly to each other. Correspondingly, the first push plate 441 mechanism and the second push plate 451 mechanism are also arranged perpendicularly to each other. The first push plate cylinder 442 pushes the first push plate 441 to place the new collar in the ring changing cavity 100 and passes through the first channel 101 to reach the second channel 102. The second push plate cylinder 452 pushes the second push plate 451 to place the new collar below the drill bit.

[0079] In addition, the first positioning plate 41 has an opening that communicates with the second channel 102. The position of this opening is the placement position of the drill bit to be processed on the positioning fixture 12. When the drill bit is ejected and separated from the old collar, the drill bit passes through this opening and is clamped by the clamping mechanism 43.

[0080] In this embodiment, to prevent the old collar from being unable to separate from the drill bit when it is ejected, the opening is narrowed at the top so that only the drill bit can pass through while the old collar is blocked. After the drill bit separates from the old collar, the old collar falls onto the positioning fixture 12 and can be manually removed. In this embodiment, the old collar is pushed out of the positioning fixture 12 by the second pushing mechanism 45 to push the new collar.

[0081] In this embodiment, as Figure 3 As shown, a recycling mechanism 47 is provided on one side of the top material mechanism 42. The recycling port of the recycling mechanism 47 is located below the first positioning plate 41. The recycling mechanism 47 is used to recycle old collars.

[0082] The recycling port of the recycling mechanism 47 is located below the first positioning plate 41 and is positioned on the side close to the opening.

[0083] When the old collar is pushed off the positioning fixture 12, it can fall into the recycling port and be recycled by the recycling mechanism 47.

[0084] Specifically, the recycling mechanism 47 includes a guide groove 471 and a recycling box 472. The recycling port is located on the guide groove 471. When the second pushing mechanism 45 pushes the new collar, the old collar moves and falls into the guide groove 471. It is then guided by the guide groove 471 and slides into the recycling box 472 for recycling.

[0085] In this embodiment, as Figure 3 As shown, a shim 110 is provided below the first positioning plate 41. The shim 110 is used to partially close the first channel 101 and the second channel 102. The shim 110 is used to support the new collar, allowing the new collar to be pushed within the first channel 101 and the second channel 102. In addition, when the shim 110 is provided, the shim 110 and the first positioning plate 41 define the cross-sectional shape of the first channel 101 and the second channel 102. It matches the first push plate 441 and the second push plate 451, making the first push plate 441 and the second push plate 451 stable when pushed within the first channel 101 and the second channel 102, without shaking. This allows the new collar to be accurately pushed under the drill bit, improving accuracy.

[0086] In this embodiment, as Figure 3 As shown, the top material mechanism 42 and the first positioning plate 41 are assembled and fixedly connected;

[0087] In the use of the advance and retraction ring device 4, if the position of the first positioning plate 41 is fixed, when the positioning fixture 12 moves to the advance and retraction ring device 4, the drill bit to be processed on the positioning fixture 12 will interfere with the first positioning plate 41 and cannot move to the opening on the first positioning plate 41. Therefore, a first moving cylinder 481 is provided on one side of the ejector mechanism 42, and a first sliding mechanism 482 is provided below the ejector mechanism 42. The first moving cylinder 481 can drive the ejector mechanism 42 to move through the first sliding mechanism 482, so that the first positioning plate 41 moves synchronously.

[0088] The first positioning plate 41 is moved away from the turntable device 1 by the first moving cylinder 481. When the positioning fixture 12 carries the drill bit to be processed and rotates to be aligned with the first positioning plate 41, the first moving cylinder 481 drives the first positioning plate 41 to slowly approach the positioning fixture 12, and the drill bit to be processed passes through the opening and the old collar of the drill bit to be processed is placed in the second channel 102.

[0089] In this embodiment, as Figure 3 As shown, specifically, the pressing mechanism 46 includes:

[0090] A first bracket 461 and a transverse cylinder 462 mounted on the first bracket 461, wherein the drive end of the transverse cylinder 462 is connected to a mounting base; and

[0091] Multiple pressure cylinders 463 are mounted on the mounting base;

[0092] Multiple pressing components 464 are respectively set at the drive end of multiple pressing cylinders 463.

[0093] In this embodiment, two pressing cylinders 463 and two pressing components 464 are provided. The two pressing components 464 are a large drill bit pressing component and a small drill bit pressing component. The pressing cylinders 463 are moved by moving the mounting base through the transverse cylinder 462 so that both the large drill bit pressing component and the small drill bit pressing component can be aligned with the drill bit to be processed. The user can select the appropriate pressing component according to the diameter of the drill bit to be processed.

[0094] In this embodiment, as Figure 6 As shown, the device also includes:

[0095] The adjusting device 5 is located near the advancing and retreating ring device 4, and is used to adjust the height of the collar on the drill bit.

[0096] Specifically, the adjustment device 5 includes:

[0097] The second positioning plate 51 has a positioning hole 511 on one side;

[0098] Adjustment mechanism 52 is disposed above the second positioning plate 51. The adjustment mechanism 52 includes an adjuster 521 and a probe 522 used in conjunction with the adjuster 521. The probe 522 is positioned opposite to the positioning hole 511.

[0099] The positioning mechanism 53 is located below the second positioning plate 51. The positioning mechanism 53 includes a positioning element 531, a positioning motor 532, and a lifting mechanism 533. The positioning element 531 is positioned opposite to the positioning hole 511. The positioning element 531 can move up and down by driving the lifting mechanism 533 through the positioning motor 532.

[0100] The second moving cylinder 541 moves the probe 522 and the second positioning plate 51 above the product, aligning the probe 522, positioning hole 511, and positioning element 531 on the same axis. The positioning motor 532 then drives the positioning element 531 upward via the lifting mechanism 533, which in turn moves the drill bit upward to the set position. The adjuster 521 fine-tunes the relative position of the drill bit and the collar via the probe 522, ensuring precise positioning of the drill bit.

[0101] In addition, the second positioning plate 51 is assembled and fixedly connected with the adjustment mechanism 52;

[0102] In the use of the adjustment device 5, if the position of the second positioning plate 51 is fixed, when the positioning fixture 12 moves to the advance and retreat ring device 4, the drill bit to be processed on the positioning fixture 12 will interfere with the second positioning plate 51 and cannot move to the positioning hole 511 on the second positioning plate 51. Therefore, a second moving cylinder 541 is provided on one side of the adjustment mechanism 52, and a second sliding mechanism 542 is provided at the bottom of the second positioning plate 51. The second moving cylinder 541 drives the adjustment mechanism 52 and the second positioning plate 51 to move as a whole through the second sliding mechanism 542.

[0103] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
