Detailed implementation manners

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0030] As Figure 1-7 shown, the present invention is a coupling processing device, including a bottom plate 1, on which there are two vertical plates 11, and a cover plate 12 is jointly provided on the two vertical plates 11; it also includes a reset component,

[0031] A second motor 601 is installed on the cover plate 12. A drive shaft 602 is provided at the output end of the second motor 601. A circular plate 603 is provided at the lower end of the drive shaft 602. A double-connected gear assembly is provided on the outer side of the circular plate 603. The outer side of the double-connected gear assembly meshes with a first rack 605 and a second rack 607, and driven by the double-connected gear assembly, the first rack 605 and the second rack 607 move in opposite directions. The number of teeth on the first rack 605 is less than that on the second rack 607. A first connecting rod 606 is provided on the first rack 605, and a second connecting rod 608 is provided on the second rack 607. An opening component is respectively provided at the lower ends of the second connecting rod 608 and the first connecting rod 606.

[0032] Preferably, the double-connected gear assembly includes a first gear 604, a second gear 609, a first ring 610, a spring catch 611, a second ring 612, a card slot 613 and a gear connecting rod 614; a first ring 610 is provided on the outer ring surface of the circular plate 603, a second gear 609 is provided at the lower end of the first ring 610, and the second gear 609 meshes with the second rack 607;

[0033] The upper outer ring surface of the first ring 610 is rotatably sleeved with a first gear 604. A second ring 612 is provided on the first gear 604. At least two card slots 613 are opened on the inner ring surface of the second ring 612. A spring catch 611 is arranged in the middle of the first ring 610, and the spring catch 611 is adapted to the card slot 613;

[0034] During operation, when the second motor 601 is started and rotates, the second motor 601 drives the drive shaft 602 and the circular plate 603 to rotate. As the circular plate 603 rotates, it will drive the first ring 610 to rotate. Since the second gear 609 is provided at the lower end of the first ring 610, during the rotation of the first ring 610, the second gear 609 also rotates synchronously, thereby driving the second rack 607 to move; since the spring catch 611 is provided on the outer side of the first ring 610 and the spring catch 611 is adapted to the card slot 613, when the first ring 610 rotates, the spring catch 611 is caught in the card slot 613, thereby driving the second ring 612 to rotate, and further driving the second ring 612 to rotate. Also, since the second ring 612 meshes with the first rack 605, when the second motor 601 is driven, the first rack 605 and the second rack 607 move relatively;

[0035] Moreover, since the first rack 605 is provided with a first connecting rod 606 and the second rack 607 is provided with a second connecting rod 608, when the first rack 605 and the second rack 607 move relative to each other, the push plate 4 also moves relative to each other, thereby driving the drill bit 42 to move relative to each other, so as to synchronously open holes in the coupling and improve the hole-opening efficiency.

[0036] The number of teeth on the first rack 605 is less than that on the second rack 607. When the first rack 605 moves as the first gear 604 rotates, the first rack 605 stretches the return spring 51 at this time. Since the number of teeth on the first rack 605 is less than that on the second rack 607, during the rotation of the first gear 604, the first rack 605 is no longer engaged with the first gear 604. At this time, the return of the return spring 51 will pull the first rack 605 back to its initial state.

[0037] At this time, the second rack 607 continues to move, driving the drill bit 42 to continue to move and pass through the hole opened by another drill bit 42, so as to discharge the debris and waste in the hole.

[0038] When the second ring 612 rotates forward, the spring catch 611 is always caught in the card slot 613 to drive the two to move synchronously. When the second ring 612 rotates backward, the second ring 612 is not restricted by the spring catch 611 at this time.

[0039] Using the second motor 601 as the power source, during its rotation process, the two drill bits 42 are synchronously driven to move relative to each other. This processing method synchronously opens holes at the same position on the coupling, greatly improving the hole-opening efficiency.

[0040] First of all, since the two drill bits 42 work simultaneously, they can complete the same processing tasks in a shorter time. Compared with the method of processing one by one with a single drill bit, the method of the two drill bits working synchronously greatly reduces the processing time and improves the overall production efficiency.

[0041] Secondly, due to the synchronous movement of the two drill bits 42, they can maintain the same rotational speed and force when opening holes in the coupling, thus ensuring the uniformity and consistency of the holes. This uniform processing effect not only improves the overall quality of the product, but also reduces the rejection rate caused by uneven processing.

[0042] Furthermore, since the two drill bits 42 share the processing tasks at the same time, the burden on each drill bit is relatively reduced, thereby prolonging the service life of the drill bit 42. During the long-term processing process, this design can significantly reduce the wear and damage of the drill bit and reduce the production cost.

[0043] Finally, the way of synchronous operation of the double drills can also ensure the cleanliness inside the hole. During the machining process, since the two drills 42 act simultaneously, they can quickly discharge the debris and waste inside the hole, avoiding the decline in machining quality caused by the accumulation of debris;

[0044] In summary, the method of opening holes in the coupling by driving the two drills 42 to move synchronously by the second motor 601 not only improves the hole opening efficiency, increases the service life of the drills 42, but also ensures the cleanliness inside the hole.

[0045] Preferably, the reset assembly includes a spring limit frame 5 and a reset spring 51. The spring limit frame 5 is provided on the vertical plate 11. The reset spring 51 is arranged inside the spring limit frame 5. The reset spring 51 is connected to the first rack 605. The first rack 605 is slidably arranged inside the spring limit frame 5; through the arrangement of the reset spring 51, it is used to drive the first rack 605 to reset to the initial state for subsequent use of the coupling.

[0046] In this embodiment, the hole opening unit includes a first motor 3, a first telescopic rod 31, a first pulley 32, a second pulley 33, a belt 34, a second telescopic rod 35, a connecting rod 36, a rotating shaft 37 and a hole opening assembly; the second pulley 33 is sleeved on the rotating shaft 37 respectively, and the second telescopic rod 35 is arranged at one end of the rotating shaft 37 respectively. The second telescopic rod 35 is connected to the vertical plate 11. A third telescopic rod 7 is arranged between the two rotating shafts 37;

[0047] The first pulley 32 is sleeved on the first telescopic rod 31. A transmission connection is formed between the first pulley 32 and the second pulley 33 through the belt 34. The opposite ends of the first telescopic rod 31 are respectively connected to the hole opening assembly. The other end of one of the first telescopic rods 31 is connected to the output end of the first motor 3. The first motor 3 is installed on one of the vertical plates 11. The other end of the other first telescopic rod 31 is installed on the other vertical plate 11;

[0048] As Figure 2 shown: the first telescopic rod 31, the second telescopic rod 35 and the third telescopic rod 7 are all rectangular telescopic rods, so that during the telescopic process of the telescopic rod, it can not only telescopic, but also rotate; driven by the first motor 3, the output power of the first motor 3 will be transmitted to the first telescopic rod 31 on the left side, thereby driving the first pulley 32 to rotate. Since a transmission connection is formed between the first pulley 32 and the second pulley 33 through the belt 34, when the first pulley 32 rotates, the second pulley 33 also rotates synchronously;

[0049] Furthermore, through the arrangement of the second telescopic rod 35 and the third telescopic rod 7, the left and right second belt pulleys 33 are supported, and at the same time, the left and right second belt pulleys 33 can be ensured to rotate synchronously. Since the first belt pulley 32 and the belt 34 are also arranged on the right side and are also connected to the first telescopic rod 31, it can be obtained that under the drive of the first motor 3, the two first telescopic rods 31 rotate synchronously, and then synchronously drive the connected hole-opening assembly to rotate synchronously, which not only improves the hole-opening efficiency but also ensures the consistency and stability of the hole-opening quality.

[0050] When the first motor 3 is started, it drives the two first telescopic rods 31 to rotate synchronously. As the first telescopic rods 31 rotate synchronously, the connected hole-opening assembly also rotates synchronously. The synchronous rotation mechanism ensures that the hole-opening assembly maintains a consistent rotational speed and angle during the processing, thus greatly improving the hole-opening efficiency. At the same time, due to the synchronous movement of the two hole-opening assemblies, they can act on the workpiece simultaneously, further enhancing the processing speed.

[0051] In addition, the synchronously rotating hole-opening assembly also ensures the consistency and stability of the hole-opening quality. During the hole-opening process, since the rotational speeds, angles, and positions of the two hole-opening assemblies are all consistent, the forces they exert on the workpiece are also uniform. This uniform force can ensure that the hole-opening effect on the workpiece surface is more uniform, avoiding defects and unevenness caused by uneven hole-opening.

[0052] Generally speaking, the drive of the first motor 3 and the synchronous rotation mechanism of the first telescopic rod 31 and the hole-opening assembly together constitute the core advantages of this hole-opening unit. They not only improve the hole-opening efficiency but also ensure the consistency and stability of the hole-opening quality.

[0053] In this embodiment, the hole-opening assembly includes a push plate 4, a chuck 41, and a drill bit 42. The opposite ends of the push plate 4 are respectively rotatably provided with chucks 41. The chucks 41 extend out of the push plate 4 and are connected to the first telescopic rod 31, and are driven by the first motor 3 to drive the chucks 41 to rotate. The opposite ends of the chucks 41 are respectively provided with drill bits 42. Driven by the motor 3, the two first telescopic rods 31 rotate synchronously, and then synchronously drive the connected chucks 41 and drill bits 42 to rotate synchronously, enabling the drill bits 42 to be used for opening holes in the coupling, which not only improves the hole-opening efficiency but also ensures the consistency and stability of the hole-opening quality.

[0054] In this embodiment, the bottom plate 1 serves as the foundation of the entire structure, and two support plates 2 are provided thereon. These two support plates 2 not only firmly support the entire structure but also play a role in stably placing the coupling in an appropriate position. The upper ends of the support plates 2 are commonly connected to a support frame 21. The upper end of the support frame 21 is open, facilitating the insertion or removal of the coupling. At the same time, one side of the support frame 21 is also open, further facilitating the placement and operation of the coupling.

[0055] To better observe the processed round holes on the coupling, an arc-shaped groove 211 is formed on the side surface of the support frame 21 close to the drill bit 42. The design of the arc-shaped groove 211 enables the staff to clearly see the situation of the round holes on the coupling during the processing, thus ensuring the processing accuracy and efficiency.

[0056] Preferably, at least two limiting springs 25 are provided on the support frame 21. A limiting plate 24 is commonly provided on the limiting springs 25. The lower end of the limiting plate 24 is slidably arranged with the bottom wall of the support frame 21.

[0057] Arc-shaped grooves 22 are respectively formed on the opposite inner sides of the inner cavity of the support frame 21. One end of each arc-shaped groove 22 is arc-shaped, and the arc-shaped groove 22 bends downward at a ninety-degree angle. A sliding rod 23 is commonly arranged in the two arc-shaped grooves 22.

[0058] When it is necessary to fix the coupling, the sliding rod 23 is pulled. The sliding rod 23 freely slides in the arc-shaped groove 22. At this time, the two ends of the sliding rod 23 slide to the position where the arc-shaped groove 22 bends downward at a ninety-degree angle. While the sliding rod 23 slides, the sliding rod 23 squeezes the coupling, thereby compressing the limiting springs 25. When the two ends of the sliding rod 23 are displaced to the position where the arc-shaped groove 22 bends downward at a ninety-degree angle, the coupling will be subjected to the pressure of the sliding rod 23 and the reaction force of the limiting springs 25, fixing the coupling, thereby preventing the coupling from moving or shaking during the processing. The sliding rod 23 contacts the edge of the coupling and applies a certain pressure, thereby further improving the stability of the coupling during the processing. Moreover, the processing accuracy and efficiency are improved.

[0059] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
