Description

Technical Field

[0001] This utility model belongs to the technical field of drill bit auxiliary equipment, specifically a device for restraining the vibration of a drill bit during initial operation. Background Technology

[0002] Drill bits are widely used in drilling operations in fields such as machining and construction. However, during initial operation, drill bits are prone to noticeable vibration due to factors such as instantaneous impact force and their own inertia. This vibration not only affects the accuracy and quality of drilling but may also shorten the lifespan of the drill bit and even pose a potential threat to the safety of operators.

[0003] Currently, while there are some devices on the market for securing drill bits, most of them use screws to tighten the screws, which is cumbersome to both tighten and loosen. Therefore, developing a device that can effectively control drill bit vibration during initial operation is of significant practical importance. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device to restrain the vibration of the drill bit during the initial operation.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A device for restraining drill bit vibration during initial operation includes a base, a support plate rotatably mounted on the upper end of the base, two slide rods fixedly mounted on the upper end of the support plate, a slider slidably mounted between the two slide rods, a drill bit motor fixedly mounted on the side end of the slider, and a constraint ring fixedly mounted on the side end of the support plate directly below the drill bit motor. A groove is formed inside the support plate, and a clamping assembly for clamping and fixing the drill bit motor is installed in the groove. The clamping assembly includes a hydraulic telescopic rod, a clamping plate, a moving block, and an anti-slip pad. The hydraulic telescopic rod is fixed within the groove inside the support plate. There are two clamping plates, symmetrically mounted within the groove of the support plate, and the clamping plates are slidably connected to the support plate. The moving block has a trapezoidal structure, with both ends slidably connected to the side ends of the clamping plates. The telescopic end of the hydraulic telescopic rod is fixedly connected to the side end of the moving block. The anti-slip pad is fixedly mounted on the side end of the clamping plate.

[0007] Furthermore, the side end of the support plate is inclined. When the hydraulic telescopic rod is extended, the moving block moves away from the hydraulic telescopic rod, at which time the two clamping plates open to both ends. When the hydraulic telescopic rod is retracted, the moving block moves towards the hydraulic telescopic rod, at which time the two clamping plates move towards the middle to achieve clamping.

[0008] Furthermore, the support plate has a first sliding groove at the bottom of the groove, and the clamping plate has a first sliding plate fixedly installed at the bottom, the first sliding plate being adapted to the first sliding groove.

[0009] Furthermore, a second sliding groove is provided on the side end of the clamping plate, and a second sliding plate is fixedly installed on the side end of the moving block, the second sliding plate being adapted to the second sliding groove.

[0010] Furthermore, a circular groove is provided at the upper end of the base, and a circular block is fixedly installed at the lower end of the support plate, with the circular block rotatably installed in the circular groove of the base.

[0011] Furthermore, the base has a disc-shaped structure, and multiple insertion holes are evenly provided at the upper end of the base along the edge of the base. A through hole is provided at the upper end of the support plate, and the through hole corresponds to the position of the insertion hole. The insertion component is fixed at the through hole at the upper end of the support plate.

[0012] Furthermore, the plug-in assembly includes a pin, a connecting plate, and a connecting spring. The connecting plate is fixedly connected to the support plate by two connecting springs. The pin is fixedly installed at the lower end of the connecting plate, and the end of the pin away from the connecting plate is inserted into the through hole.

[0013] Furthermore, four self-locking casters are fixedly installed at the lower end of the base.

[0014] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0015] Fixed connection: refers to a connection in which parts or components are fixed in place and there is no relative movement. It is divided into two types: detachable connection and non-detachable connection.

[0016] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0017] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model, by setting up a clamping assembly, can stably clamp the drill bit motor. When the hydraulic telescopic rod retracts, the moving block drives the two clamping plates to move closer to the center, thereby clamping and fixing the drill bit motor. Combined with the anti-slip pad, it can effectively prevent the drill bit motor from shaking during operation, thus restraining the vibration of the drill bit during initial operation.

[0020] 2. The support plate is rotatably connected to the base, allowing the device to adjust the working angle of the drill bit according to operational needs, thus improving the device's flexibility and applicability. Simultaneously, the support plate can be fixed at the desired angle via a plug-in assembly, ensuring stability during operation. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] A device for restraining drill bit vibration during initial operation, such as... Figures 1-5 As shown, the system includes a base 1, a support plate 2 rotatably mounted on the upper end of the base 1, two sliding rods 3 fixedly mounted on the upper end of the support plate 2, a slider 4 slidably mounted between the two sliding rods 3, a drill motor 5 fixedly mounted on the side end of the slider 4, and a constraint ring 6 fixedly mounted on the side end of the support plate 2 directly below the drill motor 5. A groove 7 is formed inside the support plate 2, and a clamping assembly 8 for clamping and fixing the drill motor 5 is installed in the groove 7. The clamping assembly 8 includes a hydraulic telescopic rod 9 and a clamping plate 1. The device comprises a movable block 11 and an anti-slip pad 12. The hydraulic telescopic rod 9 is fixed within a groove 7 inside the support plate 2. Two clamping plates 10 are symmetrically installed within the groove 7 of the support plate 2 and are slidably connected to the support plate 2. The movable block 11 has a trapezoidal structure, with both ends slidably connected to the side ends of the clamping plates 10. The telescopic end of the hydraulic telescopic rod 9 is fixedly connected to the side end of the movable block 11. The anti-slip pad 12 is fixedly installed on the side end of the clamping plate 10. This device effectively controls the initial vibration of the drill bit through "double constraint." On the one hand, the clamping assembly 8 drives the moving block 11 through the hydraulic telescopic rod 9, which in turn drives the two symmetrical clamping plates 10 to form a stable clamping of the drill motor 5. The sliding connection between the trapezoidal moving block 11 and the clamping plate 10 ensures that the clamping force is transmitted evenly. The symmetrical design ensures that the forces on both sides of the motor are balanced. The anti-slip pad 12 increases the friction to prevent the motor from slipping, thereby reducing the drill bit vibration caused by motor shaking from the source. On the other hand, the constraint ring 6 on the side of the support plate 2 is located directly below the drill motor 5, which directly forms a physical limit on the drill bit. During initial operation, it can limit the radial swing of the drill bit and work in conjunction with the clamping assembly 8 to further reduce the vibration amplitude.

[0030] As a preferred embodiment of this utility model, the side end of the support plate 2 is inclined. When the hydraulic telescopic rod 9 is stretched, the moving block 11 moves away from the hydraulic telescopic rod 9, and at this time the two clamping plates 10 open to both ends. When the hydraulic telescopic rod 9 is retracted, the moving block 11 moves closer to the hydraulic telescopic rod 9, and at this time the two clamping plates 10 move closer to the middle to achieve clamping.

[0031] In a preferred embodiment of this invention, the support plate 2 has a first sliding groove 13 at the bottom of the groove 7, and a first sliding plate 14 is fixedly installed at the bottom of the clamping plate 10. The first sliding plate 14 is adapted to the first sliding groove 13. The adaptation of the first sliding plate 14 and the first sliding groove 13 provides a precise guiding trajectory for the movement of the clamping plate 10. Since the first sliding groove 13 is located at the bottom of the groove 7 of the support plate 2, and the first sliding plate 14 is fixedly connected to the bottom of the clamping plate 10, their cooperation can strictly limit the movement direction of the clamping plate 10, ensuring that the clamping plate 10 can only move horizontally in a straight line along the groove, avoiding lateral deviation or tilting of the clamping plate 10 during movement. This stable guiding effect ensures that the two clamping plates 10 always maintain a symmetrical state when they approach or open, so that the clamping force is evenly distributed on both sides of the drill motor 5, enhancing the stability of the clamping.

[0032] In a preferred embodiment of this utility model, a second sliding groove 15 is provided on the side end of the clamping plate 10, and a second sliding plate 16 is fixedly installed on the side end of the moving block 11. The second sliding plate 16 is adapted to the second sliding groove 15. The compatibility between the second sliding plate 16 and the second sliding groove 15 ensures that the sliding connection between the moving block 11 and the clamping plate 10 is precise and firm. The shapes and sizes of the two are matched, which can limit the relative displacement between the moving block 11 and the clamping plate 10 in the direction perpendicular to the sliding direction, and avoid wobbling or deviation. This stable connection method makes the force transmission more direct and uniform when the moving block 11 drives the clamping plate 10 to move, reduces the energy loss caused by loose connection, and ensures the stability of the clamping assembly 8 during operation. This structure is the key link to realize the opening and closing action of the clamping plate 10. When the hydraulic telescopic rod 9 drives the moving block 11 to move, the second sliding plate 16 on the side end of the moving block 11 will slide along the second sliding groove 15 on the side end of the clamping plate 10, thereby pushing or pulling the clamping plate 10. Because the sliding fit between the second slide plate 16 and the second slide groove 15 is smooth, the power of the hydraulic telescopic rod 9 can be efficiently transmitted to the clamping plate 10, ensuring that the clamping plate 10 moves precisely towards the center or opens to both ends under the action of the moving block 11, thereby achieving reliable clamping or releasing of the drill motor 5 and ensuring the effective realization of the function of the clamping assembly 8.

[0033] In a preferred embodiment of this utility model, a circular groove 17 is provided at the upper end of the base 1, and a circular block 18 is fixedly installed at the lower end of the support plate 2. The circular block 18 is rotatably installed within the circular groove 17 of the base 1. The circular block 18 has a high shape compatibility with the circular groove 17, allowing it to rotate smoothly within the groove 17. This provides a stable trajectory and support point for the rotation of the support plate 2 relative to the base 1, ensuring the smoothness of the rotation process, avoiding jamming or offset, and reducing the impact of structural friction or jamming on the overall stability of the device.

[0034] In a preferred embodiment of this utility model, the base 1 has a disc-shaped structure. Multiple insertion holes 19 are evenly distributed along the edge of the upper part of the base 1. A through hole 20 is provided at the upper part of the support plate 2, with the through hole 20 corresponding to the insertion holes 19. A plug-in assembly 21 is fixed at the through hole 20 at the upper part of the support plate 2. The disc-shaped structure of the base 1, combined with the multiple insertion holes 19 evenly distributed along its edge, provides ample fixing points for multi-angle adjustment of the support plate 2. Since the through hole 20 corresponds to the insertion hole 19, when the support plate 2 rotates to different angles within the circular groove 17 of the base 1 via the circular block 18, a corresponding insertion hole 19 will always align with the through hole 20, ensuring that the plug-in assembly 21 can be smoothly inserted and stably fixed, guaranteeing the continuity and reliability of the structure during angle adjustment. This structure further improves the angle adjustment and fixing system of the device. The multiple evenly distributed insertion holes 19 mean that the support plate 2 can achieve multiple angle fixations, meeting the precise requirements for drilling angles in different working scenarios. For example, when fine-tuning the drilling angle is required, the reasonable spacing between adjacent insertion holes 19 can provide a more precise angle selection, improving the operating accuracy of the device. At the same time, the cooperation between the insertion assembly 21 and the through hole 20 and insertion hole 19 can firmly fix the rotated support plate 2 on the base 1, preventing the support plate 2 from shifting angle due to drill bit vibration or external impact during drilling operations, thereby ensuring the accuracy of the drilling position and enhancing the overall effect of the device in restraining drill bit vibration.

[0035] In a preferred embodiment of this utility model, the plug-in assembly 21 includes a pin 22, a connecting plate 23, and connecting springs 24. The connecting plate 23 is fixedly connected to the support plate 2 via two connecting springs 24. The pin 22 is fixedly installed at the lower end of the connecting plate 23, with the end of the pin 22 away from the connecting plate 23 inserted into the through hole 20. The connecting plate 23 is fixed to the support plate 2 via two connecting springs 24. When the angle of the support plate 2 needs to be adjusted, the connecting plate 23 is pulled upward, the connecting springs 24 are stretched, and the pin 22 is pulled out from the through hole 20 and the corresponding insertion hole 19. This operation is convenient and can easily release the fixation of the support plate 2. After the connecting plate 23 is released, the rebound force of the connecting springs 24 can quickly drive the pin 22 to re-insert into the through hole 20 and the corresponding insertion hole 19, realizing the automatic locking of the support plate 2. No additional manual alignment and fixing are required, improving the efficiency of angle adjustment.

[0036] As a preferred embodiment of this utility model, four self-locking casters 25 are fixedly installed at the lower end of the base 1. The self-locking casters 25 have the characteristics of flexible steering and rolling, which allows the entire device to be easily moved between different work sites without laborious handling, saving manpower and time, and improving the flexibility of operation.

[0037] Working principle and usage process of this utility model:

[0038] When fixing the drill motor 5, the clamping assembly 8 plays a crucial role. The hydraulic telescopic rod 9 serves as the power source, and its telescopic movement drives the trapezoidal moving block 11 to move. When the hydraulic telescopic rod 9 retracts, the moving block 11 moves towards it. Since the two ends of the moving block 11 are slidably connected to the second sliding groove 15 on the side of the clamping plate 10 through the second sliding plate 16, and the bottom of the clamping plate 10 is slidably connected to the first sliding groove 13 at the bottom of the groove 7 of the support plate 2 through the first sliding plate 14, the movement of the moving block 11 forces the two symmetrical clamping plates 10 to move closer to the center. The anti-slip pads 12 on the side of the clamping plates 10 tightly clamp the drill motor 5, increasing friction and preventing it from shaking, thereby reducing the vibration caused by motor instability during the initial operation of the drill bit. When the hydraulic telescopic rod 9 extends, the moving block 11 moves in the opposite direction, and the two clamping plates 10 open to both ends, facilitating the placement or removal of the drill motor 5.

[0039] Regarding angle adjustment, the circular block 18 at the lower end of the support plate 2 is rotatably mounted in the circular groove 17 at the upper end of the base 1, allowing the support plate 2 to rotate relative to the base 1 to accommodate different drilling angle requirements. After adjusting to the appropriate angle, the pin 22 in the insertion assembly 21, under the elastic force of the connecting spring 24, passes through the through hole 20 of the support plate 2 and inserts into the corresponding insertion hole 19 of the base 1, fixing the support plate 2 and preventing angle deviation during drilling from causing increased vibration.

[0040] In addition, the four self-locking casters 25 at the lower end of the base 1 facilitate the overall movement of the device, and lock after being moved to the working position to ensure the stability of the device during operation. At the same time, the drill motor 5 is mounted on the slider 4, which can slide along the slide rod 3. Together with the constraint ring 6 located directly below the drill motor 5, it further provides auxiliary constraint on the drill bit and reduces the amplitude of vibration.
