Description

Technical Field

[0001] The present invention relates to the technical field of drilling, and in particular to a drilling method and a drilling device for a flange fork. Background Art

[0002] A flange fork, a key connector in mechanical transmission systems, typically consists of a flange and a fork-shaped structure. To meet assembly and functional requirements, multiple holes must be machined into the flange fork. These holes include bolt holes for fastening, positioning holes for positioning, and shaft holes for axle pins. Currently, these holes are typically machined using a traditional drilling machine, which drills each hole sequentially by adjusting the position and angle of the flange fork.

[0003] Due to the large number of holes on the flange fork, drilling each hole sequentially makes it difficult to ensure the positioning accuracy of the flange fork during each drilling, which can easily lead to hole position deviations and affect drilling quality. Furthermore, to ensure drilling accuracy, the flange fork's posture must be frequently adjusted, interrupting the machining process and significantly reducing machining efficiency. Therefore, the existing technology has a problem of difficulty in simultaneously balancing machining efficiency and drilling quality. Summary of the Invention

[0045] The flange fork 60 consists of a flange and a fork-shaped structure. To meet assembly and functional requirements, multiple holes must be machined into the flange fork 60. Due to the large number of holes to be machined on the flange fork 60, each hole must be drilled sequentially. This makes it difficult to accurately position the flange fork 60 during each drilling operation, which can easily lead to positional deviations and affect drilling quality. Furthermore, to ensure drilling accuracy, the flange fork 60 must be frequently adjusted, disrupting the machining process and significantly reducing efficiency. Therefore, the existing technology presents a challenge in achieving both machining efficiency and drilling quality.

[0046] Example 1:

[0047] In order to solve the above problems, the present invention provides a drilling method for a flange fork 60 . The drilling method for the flange fork 60 involves a drilling device including a fixing table 10 , a main box 30 , a plurality of drill bits 40 , and a support seat 50 .

[0048] The fixed platform 10 is provided with a plurality of vertical guide channels 20, which can guide the drill bit 40 to rise and fall vertically to ensure that the drilling is vertical and avoid skew. The main chassis 30 can control the synchronous rotation and lifting of the plurality of drill bits 40 corresponding to the guide channels 20, so that each drill bit 40 can move stably along the corresponding guide channel 20 to ensure the accuracy of the drilling position. The shank 41 and the cutter head 42 of the drill bit 40 are integrally formed to enhance the overall structural strength and reduce the risk of breakage. The shank 41 is inserted into the corresponding guide channel 20, and the cutter head 42 is located at the bottom of the shank 41 for direct contact during drilling operations. The support seat 50 is located below the fixed platform 10, and a clamping position for clamping the flange fork 60 is formed between it and the fixed platform 10. It can stably clamp the flange fork 60 to prevent movement during processing, thereby ensuring the accuracy and stability of drilling, and ultimately achieving precise and efficient processing of the flange fork 60.

[0049] In this embodiment, if Figure 1 As shown, the drilling method of the flange fork 60 includes steps S10 to S70, and steps S10 to S70 are described in detail below:

[0050] In step S10, the multiple drill bits 40 of the drilling device are positioned to their initial positions, so that the shanks 41 of the drill bits 40 are inserted into the guide channels 20, and the drill bits 40 correspond one to one with the guide channels 20. This precise correspondence between the drill bits 40 and the guide channels 20 provides a basis for the stable operation of the drill bits 40 during subsequent drilling, ensuring that the drilling accuracy of the drill bits 40 will not be affected by position deviations during operation.

[0051] In step S20, based on the multiple drill bits 40 being in the initial position, the flange fork 60 is positioned to the clamping position so that the flange fork 60 is located below the drill bit 40, ensuring that the position of the hole to be processed on the flange fork 60 is precisely aligned with the drill bit 40, avoiding drilling position errors due to position deviation, thereby ensuring that the hole position of subsequent processing meets the requirements and achieves the effect of precise positioning.

[0052] In step S30, based on the flange fork 60 being in the clamping position, the drill bit 40 is controlled to rotate and descend along the first direction of rotation until the drill bit 40 is in the first position. The cutting force generated by the rotation and the descending feed motion are utilized to drill the flange fork 60. Multiple holes on the flange fork 60 are processed and formed, thereby improving the efficiency of simultaneous processing of multiple holes.

[0053] Since the shank 41 of the drill bit 40 is inserted into the guide channel 20, when the flange fork 60 is processed, most of the debris will be discharged through the spiral hole on the shank 41. However, some debris will still adhere to the surface of the shank 41 and the cutter head 42 and the inside of the guide channel 20. These remaining debris will generate friction with the inner wall of the guide channel 20 and the drill bit 40 itself as the drill bit 40 rotates. As the drilling operation continues, the heat generated by the friction continues to accumulate, causing the temperature of the drill bit 40 to rise, making it vulnerable to damage. Therefore, the present application executes step S40, based on the drill bit 40 being in the first position, and controls the drill bit 40 to rotate and rise along the first direction of rotation after the processing is completed, until the drill bit 40 is reset to the initial position for the first time. This prevents the drill bit 40 from rubbing against the processed hole wall during the rising process and causing damage to the hole wall. At the same time, the drill bit 40 returns to its initial position, so that the drill bit 40 does not enter the guide channel 20 or is located at the bottom of the guide channel 20, avoiding scratches on the guide channel 20 and affecting the guiding effect of the tool handle 41.

[0054] In step S50, upon completion of the first reset of the drill bit 40, the flange fork 60 is removed from the clamping position. This prevents collision between the flange fork 60 and the drill bit 40 during removal, protects the drill bit 40 and the processed flange fork 60, and facilitates removal of the processed flange fork 60 in preparation for the next processing, thereby improving operational safety and convenience.

[0055] In step S60, upon completion of flange fork 60 removal, the drill bit 40 is controlled to rotate and descend in a second rotational direction until the drill bit 40 is in a second position. The first rotational direction is opposite to the second rotational direction. By controlling the drill bit 40 to rotate and descend in the second rotational direction, which is opposite to the first rotational direction, the reverse rotation can be used to clean the drill bit 40, removing any debris remaining on the drill bit 40 and preventing it from affecting subsequent machining accuracy, thereby ensuring the drill bit 40 is in good condition. Preferably, the height from the second position to the initial position is greater than the length of the guide channel 20 to allow for the complete removal of any debris obstructing the guide channel 20.

[0056] In step S70, based on the drill bit 40 being in the second position, the drill bit 40 is controlled to rise until the drill bit 40 is reset to the initial position for the second time, thereby completing the drilling process. By controlling the drill bit 40 to rise from the second position and reset to the initial position for the second time, the drill bit 40 is returned to its initial state, ready for the next drilling process, ensuring the integrity and standardization of the entire drilling process, and ultimately completing the entire drilling operation.

[0057] Furthermore, when the drill bit 40 is in its initial position, its cutter head 42 is located at the bottom of the guide channel 20. This allows the cutter head 42 to extend directly from the bottom of the guide channel 20 at the start of machining, reducing the distance the cutter head 42 must travel from the inside of the guide channel 20 to the machining position. This improves machining startup efficiency and allows for rapid entry into machining. Furthermore, the drill bit 40's initial position prevents the cutter head 42 from entering and exiting the guide channel 20, which could damage the cutter head 42 from the inner walls of the guide channel 20. Therefore, the drill bit 40's location at the bottom of the guide channel 20 improves efficiency while also extending the lifespan of the cutter head 42.

[0058] Furthermore, the drilling device includes a fixed platform 10. By setting the fixed platform 10, a stable installation base can be provided for the guide channel 20. There are multiple guide channels 20 on the fixed platform 10. The guide channel 20 is arranged vertically, so that the drill bit 40 can be lifted and lowered vertically, ensuring the verticality of the drilling direction and solving the problem of skewed drilling. A receiving groove 14 is provided at the bottom of the guide channel 20, and the diameter of the receiving groove 14 is larger than the diameter of the guide channel 20. When the drill bit 40 is in the initial position, the cutter head 42 is located in the receiving groove 14. Thereby, an accommodating space can be provided for the cutter head 42 in the initial position, avoiding direct contact between the cutter head 42 and the bottom of the guide channel 20 and causing wear. The cutter head 42 is located in the receiving groove 14, which can protect the cutter head 42 in the initial state and prevent external objects from colliding with the cutter head 42. At the same time, when the drill bit 40 is controlled to rotate and descend in the first direction of rotation, the debris generated by drilling rises and is discharged along the spiral groove of the drill bit 40. The addition of the guide channel 20 causes the chip removal channel to become longer, thereby increasing the chip removal resistance. Therefore, the accommodating groove 14 is provided to store the debris generated by the cutter head 42 drilling the flange fork 60. After drilling is completed, as the flange fork 60 is removed, the fine debris naturally falls due to gravity, thereby increasing the service life of the drill bit 40. The accommodating groove 14 also allows for the continuous release of debris, thereby reducing the friction generated by the debris with the inner wall of the guide channel 20 and the drill bit 40 itself as the drill bit 40 rotates. This in turn reduces the continuous accumulation of heat generated by friction, preventing the drill bit 40 from overheating and causing damage.

[0059] The drilling apparatus further includes an electromagnetic attraction unit, which is detachably connected to the fixing platform 10. This detachable connection facilitates installation, removal, and maintenance of the electromagnetic attraction unit. The electromagnetic attraction unit is used to generate an attraction force on debris within the receiving groove 14, thereby promptly absorbing the debris generated by drilling, preventing the accumulation of debris from affecting the operation of the drill bit 40.

[0060] Step S30 includes step S31, and step S60 includes step S61. The drilling method of the flange fork 60 is performed in sequence, step S10, step S20, step S31, step S40, step S50, step S61, and step S70.

[0061] In step S31, based on the flange fork 60 being in the clamping position, the electromagnetic attraction unit is activated, controlling the drill bit 40 to rotate in a first direction and descend until the drill bit 40 is in the first position, thereby forming multiple holes in the flange fork 60. By activating the electromagnetic attraction unit when the flange fork 60 is in the clamping position, debris generated during the drilling process can be absorbed in real time, preventing it from splashing into the hole of the flange fork 60 or the guide channel 20, thereby ensuring a clean machining environment and ensuring accurate hole machining.

[0062] In step S61, upon completion of the removal of the flange fork 60, the electromagnetic attraction unit is turned off, and the drill bit 40 is controlled to rotate and descend in the second rotational direction until the drill bit 40 is in the second position. After the flange fork 60 is completely removed, the electromagnetic attraction unit is turned off, and the drill bit 40 rotates and descends in the second rotational direction. This allows previously attracted debris to be removed from the receiving groove 14 by the rotating drill bit 40 after losing its attraction force, thereby achieving dual cleaning of the receiving groove 14 and the drill bit 40, ensuring that subsequent processing is not interfered with by debris.

[0063] Furthermore, in order to provide a better guiding effect for multiple drill bits, the length of the guide channel is greater than the depth of the hole required for the flange fork; thus, this solution sets the second position below the first position, so that the drill bit 40 has a longer stroke to clean the drill bit 40 when it rotates and descends along the second rotation direction, and can more comprehensively remove the debris remaining on the drill bit 40, thereby avoiding the debris from affecting the subsequent processing accuracy and ensuring the cleanliness of the drill bit 40 to meet the re-processing requirements.

[0064] Furthermore, based on the flange fork 60 being in the clamping position, the drill bit 40 is controlled to rotate in the first rotational direction and descend until the drill bit 40 is in the first position, and the multiple holes on the flange fork 60 are formed, the rotation speed of the drill bit 40 is the first rotation speed. The first rotation speed ensures the stability of the drilling process, avoids vibration of the flange fork 60 or roughness of the hole wall caused by excessive rotation speed, and achieves the effect of accurately drilling the holes.

[0065] After the flange fork 60 is removed, the drill bit 40 is controlled to rotate in the second direction and descend until the drill bit 40 is in the second position. The drill bit 40 rotates at a second speed that is greater than the first speed. This allows the drill bit 40 to descend in the opposite direction at the second speed, which is greater than the first speed. The higher speed generates a stronger centrifugal force, more effectively removing debris attached to the drill bit 40, thereby preventing debris from remaining and affecting subsequent processing, ultimately improving the cleanliness of the drill bit 40 and the reliability of the subsequent processing.

[0066] Example 2:

[0067] In this embodiment, the present invention provides a drilling device, which is applied to the drilling method of the flange fork 60 according to any one of the first aspects. Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the drilling device includes a fixing platform 10 , a main box 30 , a plurality of drill bits 40 , and a support base 50 .

[0068] The fixing platform 10 has a plurality of guide channels 20, which are arranged vertically. The guide channels 20 can guide the drill bit 40 to move up and down vertically to ensure that the drilling direction is vertical and avoid drilling skew.

[0069] The main box 30 is located above the fixed platform 10 and can provide installation and power support for the drill bit 40.

[0070] Multiple drill bits 40 are connected to the main chassis 30 by transmission. The main chassis 30 can control the synchronous rotation and lifting of the multiple drill bits 40 to improve processing efficiency. The multiple drill bits 40 correspond one-to-one to the guide channels 20, so that each drill bit 40 can move stably along the corresponding guide channel 20 to ensure the accuracy of the drilling position. The drill bit 40 includes a shank 41 and a cutter head 42. The shank 41 and the cutter head 42 are integrally formed to enhance the overall structural strength of the drill bit 40 and reduce the risk of breakage. The shank 41 is inserted into the corresponding guide channel 20, and the cutter head 42 is located at the bottom end of the shank 41.

[0071] The support base 50 is located below the fixed platform 10, and the support base 50 and the fixed platform 10 form a clamping position for clamping the flange fork 60. This can stably clamp the flange fork 60, preventing it from moving during machining, thereby ensuring the accuracy and stability of drilling, and ultimately achieving precise and efficient machining of the flange fork 60.

[0072] Furthermore, if Figure 5 、 Figure 6As shown, a receiving groove 14 is provided at the bottom end of the guide channel 20. The receiving groove 14 can provide a receiving space for the cutter head 42 of the drill bit 40 in the initial position, preventing the cutter head 42 from being directly exposed to the outside. The diameter of the receiving groove 14 is larger than the diameter of the guide channel 20. The receiving groove 14 is connected with the guide channel 20, so that the receiving groove 14 forms a relatively open space, which is convenient for accommodating more debris and at the same time avoids excessive friction between the cutter head 42 and the guide channel 20. The connection between the receiving groove 14 and the guide channel 20 enables the drill bit 40 to enter the receiving groove 14 from the guide channel 20 or return to the guide channel 20 from the receiving groove 14, thereby ensuring the continuity of the movement of the drill bit 40 during the drilling process. At the same time, the debris is collected by the receiving groove 14, reducing the impact of the debris on the guide channel 20 and the drill bit 40, thereby protecting the drill bit 40 and maintaining the stable operation of the drilling device.

[0073] Furthermore, if Figure 6 As shown, the receiving groove 14 is a tapered groove, or the connection between the receiving groove 14 and the guide channel 20 is stepped. The receiving groove 14 is a tapered groove with an inclined inner wall, which can guide debris to the bottom of the groove, facilitating subsequent cleaning and reducing debris residue in the groove. The stepped connection between the receiving groove 14 and the guide channel 20 can also guide debris to the bottom of the groove, reducing debris residue in the groove.

[0074] Furthermore, the drilling device includes an electromagnetic adsorption unit, which is detachably connected to the fixing platform 10, allowing for easy installation, removal, and maintenance of the electromagnetic adsorption unit, facilitating subsequent inspection and replacement. The electromagnetic adsorption unit is configured to generate an adsorption force on debris within the receiving groove 14. This adsorption force on the debris within the receiving groove 14 allows for timely adsorption of debris generated during the drilling process, preventing accumulation of debris within the receiving groove 14 and preventing the debris from affecting the normal operation of the drill bit 40, thereby ensuring a smooth drilling process and reducing machining failures caused by debris.

[0075] In other embodiments, the fixed platform 10 includes a platform body 11, a bottom mold 12, and a mold core 13. The platform body 11 is detachably connected to the base film, which has multiple guide channels 20. The guide channels 20 have a receiving groove 14 at the bottom, and the diameter of the receiving groove 14 is larger than that of the guide channels 20. The base film is detachably connected to the platform body 11, and the mold core 13 is detachably connected to the base film. The mold core 13 can be adapted to different models of flange forks 60, thereby facilitating the processing of the flange forks 60. By replacing the mold core 13, different models of flange forks 60 can be processed without changing equipment, thereby reducing the cost of drilling the flange forks 60.

[0076] The drilling device also includes multiple guide sleeves, each corresponding to a guide channel 20 and fixed within the guide channel 20. The provision of multiple guide sleeves can provide more precise guidance for the movement of the drill bit 40. The guide sleeves fixed within the guide channel 20 can enhance the stability and wear resistance of the guide structure, reducing direct wear on the guide channel 20 during the movement of the drill bit 40, thereby extending the service life of the guide channel 20. At the same time, the precise guidance of the guide sleeves makes the movement trajectory of the drill bit 40 more stable, improves the accuracy of drilling, and solves the problem of drilling deviation caused by wear of the guide channel 20.

[0077] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and that in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
